Description

Modularized offshore floating type self-adaptive solar seawater desalination storage platform

Technical Field

The invention belongs to the technical field of ocean platforms, and particularly relates to a modular offshore floating type self-adaptive solar seawater desalination storage platform.

Background

With the excessive development of mariculture in recent years, the resource environment bearing capacity near the coast reaches or approaches the upper limit. Therefore, more and more mariculture industries are developing into deep open sea farming, which has become an important means for building modern marine industrial systems.

However, there are significant differences in deep open sea farming compared to traditional offshore farming. Under the general condition, the offshore aquaculture net cage in the traditional form hardly meets the actual aquaculture requirement due to the fact that the wave height of many extra-bay sea areas in China is large and the flow rate of seawater is high. Meanwhile, the typhoon happens 28 times per year in the pacific in the northwest and the south China sea, wherein the typhoon which has an influence on the coastal areas of China has 7 times on average, and the stability and the reliability of the deep sea culture are greatly tested.

In addition, in the present mariculture process, the net cages are mostly arranged without opening, however, the net cage structure of the traditional offshore culture is difficult to meet the requirement of deep and open sea culture, and the limitation of application on equipment exists. In addition, in the deep and open sea cultivation process, a special cultivation net cage structure is required, and a corresponding ocean platform is required to be arranged so as to meet the matched use in the deep and open sea cultivation process, wherein the deep and open sea cultivation process comprises a seawater desalination storage platform.

It is worth noting that the design and construction of the deep sea aquaculture net cage or the seawater desalination storage platform are provided by large shipbuilding manufacturers all the time, so that most of maritime work equipment seen by people now has the figure of ships. Taking a semi-submersible offshore floating platform as an example, the semi-submersible offshore floating platform usually comprises a large lower floating body with the bottom evolved from a ship cabin, a large upright post with the diameter of 6 meters, an upper box body with the structure consistent with that of the ship cabin and a transverse stay bar below the upright post. Such designs tend to suffer from the following problems:

such equipment can only be built by professional large shipbuilding departments, and steel with special size and performance, special material cutting and welding equipment, special docks and large hoisting equipment, professional labor-intensive industrial workers, and on-site assembly and welding are needed during construction, and the structure brought by all factors is high in construction cost, which is acceptable in the high-profit industry with offshore oil exploitation as an object, but has great cost limitation in the application in the industry fields of deep and open sea farming and the like.

Meanwhile, the platform structure of the ocean engineering equipment formed by welding the steel plates into the functional cabins and splicing the functional cabins is poor in mechanical property, and the hot spot stress of the box-type floating body is often concentrated on a specific stress concentration node connected with the box body. Moreover, the natural frequency of the box-type floating body is usually about 0.5rad/s, and the box-type floating body is extremely easy to resonate with sea waves, surges and the like, so that the stress amplitude of a key node of the floating body is the largest. When the stress exceeds the fatigue fracture stress limit of the box body material, the box type floating body cabin structure can deform or the water sealing performance fails, so that the whole ocean engineering equipment topples or loses floating and sinking.

In the development process of the ocean platform, news about accidents, capsizing and sinking of the ocean platform appears endlessly, and huge economic loss and casualties are brought. How to promote platform's efficiency of setting up, set up stability and anti-stormy wave ability has become the designer and has more and more regarded the problem.

Example (b):

referring to fig. 1-28, the modular offshore floating adaptive solar seawater desalination storage platform in the preferred embodiment of the present invention comprises a buoyant body 100, a deck assembly, and a mooring system. The buoyancy main body 100 is arranged on the sea surface in a floating mode, the deck assembly is arranged above the buoyancy main body 100 and used for placing a load (the load comprises various devices and mechanisms arranged on the deck assembly and various loads temporarily placed/appeared on the deck assembly), and the top of the buoyancy main body 100 is not lower than the sea surface when the platform works stably, so that the full-floating seawater desalination storage platform is formed. In addition, the anchoring system is correspondingly connected to the bottom of the buoyancy body 100, and is used for anchoring the buoyancy body 100 at the bottom of the ocean, so that the buoyancy body 100 is prevented from being washed away by ocean waves, and the stability of the buoyancy body 100 is ensured.

For the seawater desalination storage platform of the preferred embodiment, the buoyancy of the buoyancy body 100 under normal operation should not be less than the buoyancy threshold, and for the "buoyancy threshold", it can be defined as: when the buoyancy magnitude of the buoyant body 100 is set to the buoyancy threshold and the heavy load on the deck assembly is at the extreme, the top of the buoyant body 100 is just level with the sea level. However, in actual installation, in order to avoid that the load on the seawater desalination storage platform can meet stable use even when a small amount of load exceeds the limit load, the water level line of the seawater desalination storage platform in the full load state is adjusted to the middle level line of the buoyancy node at the top layer of the buoyancy main body 100, so that if the load on the seawater desalination storage platform is further increased, the buoyancy main body 100 can also provide buoyancy by changing the draft.

Specifically, the buoyancy body 100 in the preferred embodiment is formed by one buoyancy module or is assembled by a plurality of buoyancy modules sequentially connected and disposed in the horizontal direction and the vertical direction, and the buoyancy modules are sequentially assembled by a plurality of buoyancy adjustable points 1 arranged in a spatial array in the preferred embodiment.

As shown in fig. 11 and 12, the buoyancy adjustable points 1 in the preferred embodiment include, but are not limited to, two types, i.e., a first buoyancy adjustable point 101 and a second buoyancy adjustable point 102, each of which includes a spherical node buoyancy body and a plurality of horizontal connecting members 103 disposed on an outer circumferential ring of the node buoyancy body, and two vertical connecting members 104 disposed on upper and lower sides of the node buoyancy body, and the greatest difference is the difference in the number of horizontal connecting members 103 disposed on the outer circumferential ring. For example, in the preferred embodiment, the number of the horizontal connecting members 103 provided on the outer periphery of the first buoyancy adjustable point 101 is 6 at intervals, and the number of the horizontal connecting members 103 provided on the outer periphery of the second buoyancy adjustable point 102 is 4 at intervals. Meanwhile, the horizontal connecting members 103 are preferably arranged at equal intervals, that is, each horizontal connecting member 103 in the first buoyancy adjustable point 101 is arranged at an interval of 60 °, and each horizontal connecting member 103 in the second buoyancy adjustable point 102 is arranged at an interval of 90 °. Through the corresponding setting of horizontal connecting piece 103 interval angle, can realize that the correspondence of different cross section shape buoyancy modules is assembled, like the buoyancy module of transversal personally submitting hexagon or rectangle, satisfy different setting demands and the application demand under the different environment.

In the preferred embodiment, the nodal buoyancy bodies of the buoyancy-adjustable points are spherical, but it is obvious that the above-described structure is not the only arrangement of nodal buoyancy bodies, which may also be arranged in an ellipsoidal shape, a cylindrical shape, a quadrangular prism shape, a pentagonal prism shape, a hexagonal prism shape, an octagonal prism shape, etc., as needed in actual arrangement. Meanwhile, the diameter of the buoyancy adjustable point 1 in the preferred embodiment is generally between 1 and 6m, and more preferably 2m, and the diameter of the horizontal connecting member 103 and/or the vertical connecting member 104 is generally 150 to 1200 mm.

Further, the buoyancy adjustable point 1 in the preferred embodiment is a thin-walled hollow structure forming a cavity therein, in which an elastic bladder 111 is disposed, as shown in fig. 13. Through the setting of elastic air bag 111, can be divided into inside and outside two parts with the cavity, note it as inboard cavity and outside cavity, inboard cavity wherein is used for holding gas, and the outside cavity is used for holding the water, and through adjusting the mutual proportion of air inlet and exhaust volume, water inlet and exhaust volume in the casing, can adjust the buoyancy of this buoyancy adjustable point 1. Obviously, the positions of the gas and the water in the inner/outer cavities can be interchanged according to actual needs.

Further, an air inlet valve 108 and an air outlet valve 109 are arranged corresponding to the inner side cavity, one end of the air inlet valve 108 is communicated with an air source, the other end of the air inlet valve is communicated with the inner side cavity, one end of the air outlet valve 109 is communicated with the inner side cavity, and the other end of the air outlet valve is communicated with an air extraction device. The two air valves are one-way valves, and the adjustment of the volume of the elastic air bag 111 can be realized through the corresponding control of the two air valves. Correspondingly, a water inlet and outlet valve 110 is arranged corresponding to the outer cavity, one end of the water inlet and outlet valve is communicated with the outer cavity, the other end of the water inlet and outlet valve is communicated with the outer side of the buoyancy adjustable point 1, and the volume of the outer cavity can be adjusted by expanding or reducing the volume of the elastic air bag 111, namely, the water body in the outer cavity is automatically sucked or discharged, so that the buoyancy of the buoyancy adjustable point 1 is adjusted.

In a preferred embodiment, the buoyancy adjustment corresponding to the buoyancy adjustable point 1 is provided with an air supply adjusting mechanism, which is preferably disposed on the upper deck of the platform or directly disposed on the buoyancy adjustable point 1 of the buoyancy main body 100, and the air supply adjusting mechanism is communicated with the air inlet valves 108 of one or more buoyancy adjustable points 1 through pipes. Of course, the intake valve 108 and the exhaust valve 109 of the preferred embodiment may be combined into one. In addition, a filtering mechanism can be correspondingly arranged at the outer end of the water inlet and outlet valve 110 to reduce solid impurities from entering the outer cavity.

Through the arrangement of the buoyancy adjustable points 1, the corresponding control of the buoyancy can be realized, when the peripheral wall surface of the elastic air bag 111 abuts against the inner side wall surface of the thin-wall hollow structure, the volume of the outer side cavity is minimum, and the buoyancy of the buoyancy adjustable points 1 is maximum; on the contrary, when the amount of gas in the elastic air bag 111 is small enough, the elastic air bag 111 is compressed to the limit, most of the thin-wall hollow structure is filled with water, and the buoyancy of the buoyancy adjustable point 1 is minimum. However, even if the ratio of gas and liquid in the buoyant body is adjusted, the actual configuration is not limited to the above-described specific configuration, and another configuration may be preferable as needed, and for example, in another preferred embodiment, the elastic bladder 111 may be eliminated, and the gas inlet/outlet adjusting mechanism and the liquid inlet/outlet adjusting mechanism may be provided separately for the buoyant body, and the gas-liquid ratio in the buoyant body may be directly adjusted, thereby adjusting the buoyancy.

Further, in the preferred embodiment, a plurality of first buoyancy adjustable points 101 are sequentially connected on a plane to form a single-layer buoyancy unit in a hexagonal shape, and then a plurality of layers of buoyancy units are connected in a stacked manner in a vertical direction to form a buoyancy module in a hexagonal prism shape as shown in fig. 5 and 6. Then, the buoyancy body 100 can be arranged by correspondingly assembling the plurality of buoyancy modules in the horizontal direction and the vertical direction. For the first buoyancy adjustable point 101, buoyancy modules formed by corresponding assembly are in a hexagonal prism structure, and a plurality of hexagonal prisms can be assembled in a cylindrical surface connection mode and an end surface connection mode to form the integral buoyancy main body 100. Of course, for the second buoyancy adjustable points 102, they may be assembled to form a buoyancy module in a "quadrangular prism" structure.

For a single buoyancy module, it can be regarded as formed by correspondingly connecting a plurality of node buoyancy bodies arranged in an array in space by using a space truss structure formed by a plurality of horizontal connecting pieces 103 and a plurality of vertical connecting pieces 104, and the buoyancy of the module is often determined by the number of buoyancy adjustable points 1 in the buoyancy module per unit volume and the buoyancy control of each buoyancy adjustable point 1. Meanwhile, the volume of the buoyancy module is often determined by the area of a single-layer buoyancy unit and the number of the arranged layers of the buoyancy units.

Specifically, the area of the single-layer buoyancy unit is determined by a horizontal node modulus l and the number S of unit nodes, wherein the horizontal node modulus l is the central distance after the two adjacent buoyancy adjustable points 1 are connected, and is 3m in the preferred embodiment; the number S of the unit nodes is the set number of the buoyancy adjustable points 1 on each side of the buoyancy unit, and is 4 in figure 5; meanwhile, the unilateral center distance of the buoyancy unit is 12 m. In actual arrangement, the closer the value of the horizontal node modulus is to the diameter of the buoyancy adjustable point 1, the greater the density of the buoyancy adjustable points in the single-layer buoyancy unit is, and the greater the buoyancy adjustable range of the correspondingly formed buoyancy unit is. According to the actual setting requirement, the buoyancy of the buoyancy unit can be adjusted by changing the distribution density of the buoyancy adjustable points 1 in the buoyancy unit, and the obtained buoyancy module is divided into a heavy-load buoyancy module, a medium-load buoyancy module and a light-load buoyancy module.

Considering that the design load of the seawater desalination storage platform is usually not large, a medium-load buoyancy module or a light-load buoyancy module is usually adopted. At this time, at least one truss rod 10 may be correspondingly disposed between adjacent buoyancy adjustable points 1, as shown in fig. 5 and 6, that is, the horizontal connecting members 103 of two adjacent buoyancy adjustable points 1 are respectively connected to one end of the truss rod 10, so as to correspondingly adjust the number of the buoyancy adjustable points 1 in a unit area, and change the load capacity of the buoyancy module or the size of the buoyancy adjustable range. If the flexible connecting member 2 is disposed between the two buoyancy adjustable points 1, the horizontal connecting member 103 of the two buoyancy adjustable points 1 may be connected to a truss rod 10, and then connected to one end of the flexible connecting member 2 through the truss rod 10, as shown in the arrangement form of a part of the buoyancy adjustable points 1 in fig. 5.

Furthermore, the plurality of layers of buoyancy units can be respectively connected in the vertical direction to form a buoyancy module with a certain volume. For example, the buoyancy body 100 in fig. 5 and 6 includes a buoyancy module having two layers of buoyancy units, that is, the number of vertical nodes is 2, and the two layers of buoyancy units are rigidly connected in the vertical direction by the vertical connecting member 104, so that the force integrity of the buoyancy body 100 in the vertical direction can be sufficiently ensured, and the level of each position of the buoyancy body 100 during operation can be ensured. When vertically spliced, the distance between two vertically adjacent buoyancy adjustable points 1 is a vertical modulus h, which in the preferred embodiment is 2.5 m. In general, if the buoyancy of the buoyancy module is ensured, the vertical modulus should be as close as possible to the diameter of the buoyancy adjustable point 1 on the premise of meeting the requirements of the production and installation process. Of course, when the buoyancy requirement of the buoyancy body 100 is not high or the number of the buoyancy units of the buoyancy body 100 is not large, the truss rods 10 with a certain length may be correspondingly disposed between two vertically adjacent buoyancy adjustable points 1, that is, the buoyancy adjustable points 1 may be vertically and directly rigidly connected by the vertical connecting member 104, or may be rigidly connected by the truss rods 10.

In actual setting, the number of the buoyancy units in a single buoyancy module is 2-4, and the buoyancy units can be optimized according to actual assembly and design requirements. Meanwhile, in the same seawater desalination storage platform, the number of the buoyancy modules can be a plurality of buoyancy modules which are sequentially arranged in the horizontal direction or a plurality of buoyancy modules which are sequentially arranged in the vertical direction.

It is further preferred that the buoyancy adjustable point 1 in the buoyancy body 100 may also be partially replaced by a storage node, further preferably a spherical storage node as shown in fig. 15.

The common characteristics of the two are that the storage node can lower the center of gravity and improve the stability of the buoyancy body 100; make full use of the storage space of self, improved self-sustaining power and duration, and provided better closure, storage temperature stability need not to carry out frequent goods and materials through boats and ships and transports and supply.

When the storage nodes are used for storing gaseous materials, the storage nodes can be used for storing compressed gas, and each storage node can provide a gas source for buoyancy adjustment of one or more buoyancy adjustable points 1 on the periphery. The structure of the storage node for storing compressed gas can be designed independently and can be similar to the buoyancy adjustable point 1, except that an elastic air bag, a water inlet and outlet port, a water inlet and outlet valve, a water inlet filter and the like are removed on the basis of the storage node, and an air inlet valve, an exhaust valve and the like are reserved. The air inlet valve can be communicated with the outside and is used for periodically supplementing the compressed air from the outside or supplementing the compressed air by a pipeline at proper time; the exhaust valve of the storage node for storing compressed gas is communicated with the intake valves 108 of the buoyancy adjustable points 1. By arranging the storage node for storing the compressed gas, the autonomous buoyancy adjustment can be completed without depending on external power and gas sources on the application occasion without frequently adjusting the buoyancy; the design of the gas supply and exhaust pipelines in the truss rod piece can be greatly simplified, and the maintenance difficulty is reduced.

Specifically, in the preferred embodiment mooring lines 6 are attached at one end to vertical connectors 104 at the bottom of buoyancy adjustment points 1 and at the other end to gravity anchor blocks 7. The gravity anchor block 7 is shown in fig. 22 and 23, and comprises a block body 701 in a block structure, wherein a mooring line hanging lug 702 is arranged at the top of the block body 701 and is used for connecting one end of a mooring line 6; meanwhile, the bottom of the block 701 is provided with a plurality of grip teeth 704, and a front chamfer 703 is provided at one side of the block 701. With the arrangement of the ground gripping teeth 704, a reliable arrangement of the gravity anchor block 7 on the sea floor can be achieved, avoiding that the gravity anchor block 7 moves on the sea floor under the influence of deep ocean currents or sea bottom animals. In addition, anti-rollover bar members 705 are respectively arranged on two sides of the block body 701, so that rollover of the gravity anchor block 7 at the bottom of the ocean is avoided, and the stability of arrangement of the gravity anchor block 7 is further ensured.

To ensure the stability of anchoring at each position in the circumferential direction of the bottom of the buoyant body 100, the number of gravity anchors 7 in the preferred embodiment is plural, for example, when the planar shape of the buoyant body 100 is hexagonal, the number of gravity anchors 7 is 6, and the gravity anchors are respectively arranged corresponding to the 6 buoyancy modules in the circumferential direction; and when the plane shape of the buoyancy body 100 is rectangular, the number of the gravity anchor blocks 7 is 4 or 8 arranged at intervals in the circumferential direction.

Further preferably, each mooring line 6 forms a certain inclination angle with the seabed surface when being arranged, and the gravity anchor block 7 is positioned outside the area of the buoyancy main body 100 facing the seabed surface, so that the stability of the seawater desalination storage platform can be ensured by further utilizing the mutual restraint among the mooring lines 6.

Preferably, to further ensure the stability of the mooring line 6 when it is installed, in a preferred embodiment, the first buoyancy adjustable point 101 or the second buoyancy adjustable point 102 may be modified to a third buoyancy adjustable point 105 as shown in fig. 14, in which third buoyancy adjustable point 105 a mooring line channel 106 is provided between the two vertical connecting members 104, and the mooring line channel 106 communicates with the end faces of the two vertical connecting members 104 for the passage of one end of the mooring line 6. Correspondingly, the lifting column 3 is arranged in correspondence with the third buoyancy adjustable point 105 in a configuration as shown in fig. 18, 19, wherein the lifting column 3 comprises a column 301 and end connections 302 arranged at both ends of the column 301, which end connections 302 may preferably be flanges when actually arranged. Meanwhile, a mooring cable pipe 303 penetrating through two end faces is axially arranged in the middle of the column 301. In addition, in order to reduce the abrasion of the mooring line 6, an abrasion-proof connector 107 is provided at the bottom of the buoyancy body 100, and can be correspondingly connected to the bottom of the third buoyancy adjustable point 105 at the bottom of the buoyancy body 100, so that the mooring line 6 can contact with a smooth piece at the bottom of the abrasion-proof connector 107 after being straightened, and the smooth piece can be a circular ring structure with a certain radian on the surface, namely, the contact part of the mooring line 6 and the buoyancy body 100 is an arc surface, thereby reducing the degree of local abrasion.

Through the arrangement, after the buoyancy body 100 is in butt joint with the lifting upright 3, the mooring cable 6 can sequentially pass through the mooring cable channels 106 from the bottom of the buoyancy body 100 and then penetrate into the mooring cable pipeline 303, and then pass through the upper deck 5 of the platform after passing through the mooring cable pipeline 303 until being connected with the corresponding anchor machine on the deck. Therefore, the mooring line 6 can be tightened or loosened by operating the anchor machine, so that the posture of the full-floating offshore floating platform can be adjusted. To achieve this, the buoyancy adjustable points 1 of the buoyant body 100 are spliced using the third buoyancy adjustable point 105, or the third buoyancy adjustable point 105 is selected only in the vertical row at the location of the mooring line 6 connection.

In practical use, the buoyancy of the buoyancy adjustable point 1 below the buoyancy main body 100 can be properly reduced, so that the center of gravity of the whole seawater desalination storage platform is reduced, and the stability and wave resistance of the seawater desalination storage platform are improved. As to how to specifically adjust the buoyancy of each buoyancy adjustable point 1 in the vertical direction of the buoyancy body 100, the buoyancy may be optimized according to actual needs, for example, the buoyancy of the vertical single-row upper buoyancy adjustable points 1 may be sequentially reduced from top to bottom, or the buoyancy of the buoyancy module at the bottom of the buoyancy body 100 may be reduced, or the buoyancy of several layers of buoyancy units at the bottom of the buoyancy body 100 may be reduced, etc.

During the in-service use, the processing raw and other materials (sea water) of sea water desalination storage platform and energy supply are provided by corresponding equipment on the platform by oneself, do not need external supply, only need carry out a small amount of manual control or maintain, and the energy source is the desalination water of output constantly, for other platforms in the ocean or facility provide the fresh water supply, reduces the cost of transportation of marine fresh water supply, promotes the convenience that ocean platform set up and use. In addition, for a single seawater desalination storage platform, the set working states at least comprise the following working states:

1. a normal low-load state in which the buoyant body 100 is mostly protruding above sea level, which is the light-load waterline shown in fig. 1;

2. a normal high load condition in which the draft of the buoyant body 100 is increased and the increased load on the deck assembly is fully or partially offset by the buoyancy of the buoyant body 100; when the load on the deck assembly reaches the design limit, the draft of the buoyant body 100 becomes large, at which point the sea level is the heavy waterline shown in fig. 1;

3. above a limit load condition in which the increased load on the deck assembly is greater than the buoyancy of the buoyant body 100, the draft of the buoyant body 100 has reached a maximum (fully submerged in seawater); at this time, the buoyancy of the buoyancy body 100 needs to be adjusted, so that the buoyancy of the whole seawater desalination storage platform is increased, and the top of the buoyancy body 100 is adjusted to be above the sea level.

The first two states belong to the operation state of the seawater desalination storage platform during normal operation, and the last state often occurs under the conditions that the load on the deck component is suddenly increased, part of buoyancy adjustable points fail or the surging effect is too large, and at the moment, the seawater desalination storage platform can be adjusted by the buoyancy corresponding to the buoyancy adjustable points to recover the normal operation state. Furthermore, if the offshore vessel in the preferred embodiment is located offshore or at a small depth in the sea, the buoyant body 100 may be submerged while ensuring that the deck assembly protrudes above the water surface.

Compared with the method that the buoyancy main body 100 needs to be assembled in advance in a shipyard and then transported to a target sea area through a large barge in the traditional ocean platform setting process, the assembling process and the transporting process of the buoyancy main body 100 in the preferred embodiment have obvious advantages and flexibility, can be directly and quickly assembled offshore, and can be transported to the target sea area in a towing manner. Of course, the buoyancy nodes and the truss rods 10 may be transported to the target sea area and then correspondingly assembled.

In addition, the transportation of the components such as the upper deck 5 and the lower deck 4 of the platform can be carried out in a mode of assembling and dragging, the assembled deck modules are fixed on the assembled buoyancy main body 100, and then the assembled buoyancy main body is dragged, so that the use of large ships can be avoided. Of course, the materials such as the metal grating 511 can also be transported to the target sea area, and the platform upper deck 5 and the platform lower deck 4 are correspondingly assembled on the lifting upright 3 which is arranged.

In addition, when the height of the buoyancy body 100 in the vertical direction is large and transportation is performed in a towing manner, the buoyancy body 100 can be towed horizontally after being turned over by 90 degrees in the transportation process, that is, each vertical connecting piece 104 of each buoyancy adjustable point 1 is switched from the vertical direction to the horizontal direction, and the buoyancy of each buoyancy adjustable point 1 is adjusted to the maximum (the draught is minimum). So set up, can bring abundant facility for the dragging of buoyancy main part 100, guarantee the efficiency and the stability of dragging. And (3) dragging and transporting the buoyancy main body 100 to a target sea area, changing the gravity center position of the buoyancy main body 100 by adjusting the buoyancy in the buoyancy adjustable point at the corresponding position, realizing the adjustment of the draft of the buoyancy main body 100 in the seawater and the overturning of the setting direction, and finally adjusting the buoyancy design value and the setting direction of the buoyancy main body 100. However, considering the horizontal flexible connection between the buoyancy adjustable points 1, before the buoyancy main body 100 is turned for 90 degrees, a plurality of horizontal connecting rods may be respectively arranged at the top and the bottom of the buoyancy main body 100, and the horizontal connecting rods are correspondingly connected with the vertical connecting pieces of the buoyancy adjustable points at the top, that is, the buoyancy adjustable points 1 in each row are rigidly connected, so as to avoid the displacement between the buoyancy units at each vertical layer after turning and the damage to the flexible connecting pieces 2.

The modular offshore floating type self-adaptive solar seawater desalination storage platform is simple in structure and convenient to set, and can quickly realize the assembly of the buoyancy main body and improve the setting efficiency of the platform through the array arrangement and connection of the buoyancy adjustable points in the space; meanwhile, once part of the buoyancy adjustable points fail or part of the upright columns fail, the buoyancy of other intact buoyancy adjustable points can be correspondingly adjusted, so that the balance of the overall stress of the buoyancy platform is ensured, the seawater desalination storage platform is prevented from rapidly failing and turning over, and sufficient time is obtained for emergency repair and rescue of the seawater desalination storage platform. Secondly, by utilizing the flexible connection of the buoyancy adjustable points in the horizontal direction and the rigid connection in the vertical direction, the wind and wave resistance of the buoyancy unit and the buoyancy main body can be improved while the vertical stability is ensured, and the layered buffering of the sea wave acting force is realized. In addition, the seawater desalination and storage component and the solar power generation and storage component are correspondingly arranged, so that the seawater desalination treatment process is realized, the whole process can effectively adapt to the deep sea environment arranged by the platform, excessive energy supply and material supply are not needed, the whole process is good in continuity, and the energy is saved and the environment is protected.
