Description

Intelligent new energy floating type offshore pipeline truss connection type deep-open sea cultivation complex

Technical Field

The invention belongs to the field of ocean engineering devices, in particular to deep-open sea cultivation equipment, and particularly relates to an intelligent new energy floating type offshore pipeline truss connection type deep-open sea cultivation complex.

Background

Compared with the international culture technology, the offshore mariculture technology in China is mature, mainly adopts a household small-scale production mode, has no scale effect, is difficult to support the large-scale production mode of the deep and open sea culture, and really has little experience of the deep and open sea culture. Besides the fact that fishing boats and breeding equipment lag behind other advanced countries, deep and open sea breeding also faces the problem that natural sea conditions are more complex.

The natural geographic environment becomes a great objective factor affecting the deep-open sea cultivation. The coastal sea condition of China is more complex than other developed countries, the coastal of China is shallow, the pollution is heavy, typhoons are more, the wind-avoiding harbor is less, the sea condition is bad, and the like. 60% typhoons are concentrated in the southeast coast of China, which is extremely unfavorable for deep sea water production and cultivation in China.

In addition, the deep-open sea aquaculture industry chain of China lacks policy and fund support, and a support system is not established, for example: 1. a large number of qualified seedlings which are matched with the cultivation net cages with the volume of tens of thousands of cubic meters are required to be put into one-time cultivation; the net cage is used for harvesting seasons, and the capability of processing thousands of tons of fished objects and the capability of transporting and accommodating cold chain logistics in the market are required to be treated in a short period of time. The offshore cold chain logistics technology cannot realize seamless connection from sea to land to dining tables, and the life guarantee system of deep and open sea breeders is not perfect (such as fresh water and fresh vegetables). The development of a new deep-open sea culture space is a strategic requirement for guaranteeing the food protein supply of people, a new deep-open sea culture mode needs to be explored, a key engineering technology is overcome, and the trend of the aquaculture industry in China is promoted to be deep blue.

The development of the fishery equipment such as the key technology and major equipment development, the development of the deep sea large-scale cultivation platform, the large-scale cultivation boat, the deep diving observation, the automatic measurement and classification of the size of the fish body, the behavior observation and counting of the fish, the automatic feeding, the culling of dead fish, the harvesting of the cultivated fish, the field processing and the like is enlarged. The method has the advantages that the interconnection and intercommunication of enterprises in the relevance and commonality fields are guided, the deep-open sea cultivation system of a whole industry chain with combination of 'raising-catching-adding' and 'sea-island-land' is constructed, national strategic investment of policies, funds and the like is increased, inclination is given from industrial policies and scientific research expenses, multiparty capital is introduced, an enterprise platform is built, and a brand-new industry chain mode is formed.

The traditional offshore net cage culture mode is a (net cage and working ship) mode, a plurality of culture net cages are distributed on the offshore close sea area, the net cages are charged with feeding and maintenance by small working ships which come and go to an onshore base several times a day, and the culture mode is generally only suitable for small-scale non-intelligent traditional culture close to the shore. However, as the cage culture goes to deep sea, the defects of the cage culture are revealed. In the large-scale intelligent deep and open sea net cage cultivation process far away from coastline, such as the coastal (net cage and working ship) cultivation mode, not only is economic and rationality lacking, but also the mode is not feasible in the actual operation of the deep blue first large-scale open sea net cage in China. The traditional offshore net cage culture mode is a (net cage-transport ship) mode, and typical prior technologies such as CN107343482A and CN105918198A distribute a plurality of culture net cages on offshore close sea areas, the net cages are charged with feeding and maintenance by a plurality of small transport ships which travel to and from an onshore base every day, and the culture mode is generally only suitable for small-scale non-intelligent artificial culture on offshore.

As the cage culture goes to the open sea step by step, the defects of the cage culture are shown:

first, if the cage is placed in the sea area more than hundred kilometers from the coast, the carrier will travel for more than ten hours a second time, and it is obviously impossible to travel a plurality of times a day.

Secondly, if severe weather and sea conditions are met, the transport ship cannot go out of the sea, the net cage cannot be fed, and the cultivation process is interrupted.

Thirdly, the cultivation net cage is far away from the coast, and the monitoring, the regulation and the maintenance of the net cage are extremely difficult.

Fourth, in harvest season, fish can not be processed and refrigerated in time after water is obtained, leading to the front end cold chain loss, seriously affecting the quality of fish.

Fifth, the underwater aquaculture conditions cannot be monitored in time and other unaccounted for adverse factors.

The analysis shows that in the large-scale intelligent cultivation net cage cultivation process far away from the coastline, such as the on-edge (net cage-transport ship) cultivation mode, the method is completely infeasible, and the actual operation of the deep blue first large cultivation net cage in China also proves that the mode is not feasible.

In the aspect of the cultivation net cage, two outstanding problems of wind and wave resistance and benefit output are also existed.

In deep open sea cultivation, the cultivation equipment needs to be fixed in a certain area, so that the cultivation equipment has strong wind and wave resistance capability, strong energy source giving capability and self-sustaining capability, and can avoid the wind and wave before the extreme wind and wave comes. The research shows that when the sea waves come, the action strength of the sea waves is reduced along with the increase of the distance from the sea surface, and when the distance from the sea surface is 6-7 meters, the action strength of the sea waves is only about 10% of the sea surface. Therefore, if the cultivation net cage is submerged to a semi-submerged state of 6-10 meters below the sea level before a large storm comes, the damage of stormy waves to cultivation equipment and cultivation objects can be effectively avoided.

The problem that the deep water net cage is deformed by ocean currents cannot be ignored, and under the condition that the water flow is 1 m/s, the volume loss rate of the net cage can be up to 80%, so that the culture water body is greatly compressed, and the growth of fishes is not facilitated.

The cleaning and replacement of the netting mainly depend on manual operation, the underwater operation difficulty is high, and the technical requirement for pollution prevention is high.

The problem of stress response of fishes in aquaculture is also prominent, the environment of deep and open sea aquaculture is more complex, factors such as wind, air pressure, water flow, temperature, illumination, salinity and the like are numerous and uncertain, the existing net cage limits natural actions of fishes to overcome the stress response, and lacks technical means and capability of adapting and adjusting the environment, so that the stress response of fishes is serious and uncontrollable, and the damage of the fishes is caused, so that the fishes grow slowly, have low reproductive capacity, have low immune function, increase morbidity, even die suddenly and the like.

Moreover, the net boxes such as the CN109874716A have the functions of suspension ropes and floating, but the net boxes are integrally used for vertical floating, and in the harvesting process, the direct pumping effect is poor due to the overlarge volume of the culture water body, and the net boxes are usually required to be caught in a net collecting mode, but the net boxes and the net bodies are required to be separated firstly by relying on external ship machinery, entanglement and incomplete separation are easy to occur, and the net is broken by machinery to cause great loss of fishes, so that the net collecting of the machinery is carefully performed slightly, time is very consumed and the efficiency is low (the same is true when the net is cleaned and replaced). The problem is temporarily solved in unpredictable severe external environments such as wind and current waves, the problem is more prominent, the ship sailing book is a big problem, even if sailing is carried out, the window period is not enough to finish fish collection or transfer, the strength of a general suspension net cage is not enough, and the risk avoiding capability is also not enough, so that the suspension net cage frequently has the accident that the fish is destroyed after storm, and huge economic loss is brought.

The net cage frame is constructed and expanded in a modularized manner by truss nodes and truss members, and the net cage frame can be in various shapes such as a sphere, a cylinder, a quadrangular prism, a penta-prism, a hexa-prism, an octa-prism and the like. The shape of the net cage frame recommended by the invention is regular hexagonal prism.

As shown in fig. 12a-d, at least part of the cage frame is a multi-layer truss in the inner-outer direction, the multi-layer truss comprises a buoyancy adjustable layer and a buoyancy non-adjustable layer, the innermost layer is the buoyancy non-adjustable layer, and the outer side of the innermost layer at least comprises one buoyancy adjustable layer. Further, in the multi-layered truss in the inner-outer direction, the buoyancy-adjustable layers and the buoyancy-non-adjustable layers alternate in sequence.

The truss nodes comprise buoyancy adjustable nodes 10 (preferably buoyancy adjustable nodes) and buoyancy non-adjustable mechanical nodes 11 (preferably spherical mechanical nodes), and the truss members comprise inter-node connecting rods 12, mechanical inter-node connecting rods 13, inter-layer inter-node connecting rods 14 and truss reinforcing cross diagonal bracing members 15.

The buoyancy adjustable layer comprises the buoyancy adjustable node 10 and the inter-node connecting rod 12, and the buoyancy non-adjustable layer comprises the mechanical node 11 and the mechanical inter-node connecting rod 13; the layers are connected by the inter-layer node links 14 between the corresponding truss nodes.

The buoyancy adjustable node 10 is a thin-wall hollow shell (preferably a thin-wall hollow shell) which is expanded compared with truss rods, and the hollow node is used for generating the buoyancy required in the operation of the aquaculture net cage 1 and adjusting the floating, carrying capacity and underwater posture of the aquaculture net cage 1 on the premise of keeping the mechanical property of the original node, wherein the underwater posture adjustment comprises switching between any two of a generally vertical state, a generally horizontal state and a rolling state in a vertical plane. The buoyancy adjustable joint 10 adjusts buoyancy in a manner of adjusting the mutual proportion of the air intake and exhaust amount and the water intake and exhaust amount in the shell.

The buoyancy non-adjustable layer is at least partially fixed on the innermost layer in the culture net, and a closed culture water space is formed.

The device of the culture net cage at the truss node is called a node buoyancy device, the shape of the node buoyancy device can be arbitrary in theory, the optimization of the mechanical property and the material volume comparison of the buoyancy node device is considered, the shape of the first-selected expanded buoyancy adjustable node is a hollow spherical body, and the interior of the spherical body cavity is provided with lighter-weight gas or other light materials, which are collectively called a buoyancy adjustable node. The center of the buoyancy adjustable node is the center of the truss mechanical node. In a specific application, the buoyancy nodes are combined in a mode corresponding to the structural relationship and arranged according to a certain space rule. Whatever the shape, the effect of generating the primary buoyancy, even the vast majority of the buoyancy, is the same. For example, "deep blue No. 1" of the prior art, the buoyancy required in the operation of creating the aquaculture net cage 1 is the lower float, there is no buoyancy node of the present invention; some prior art systems have rods and rod nodes, but the buoyancy required to create the operation of the aquaculture net 1 is rod and not rod nodes, which cannot be referred to as buoyancy node devices in the sense of the present invention.

Because the buoyancy adjustable nodes and the mechanical nodes are independently and uniformly distributed on each truss node of the truss structure, the whole structure generates supporting buoyancy corresponding to the structure, and the stress distribution state of the whole net cage frame is improved.

Due to the independence between each buoyancy-adjustable point device, when the buoyancy of the individual buoyancy-adjustable points fails, the overall buoyancy level of the whole aquaculture net cage 1 is still maintained above a safe level, thereby ensuring the safety of the aquaculture net cage 1.

The buoyancy node truss structure has the characteristics of light weight, high industrialization degree, high overall strength and rigidity, easy assembly and expansion, low investment cost and the like. The floating type floating net cage can completely meet the requirements of strength and safety, replaces the traditional large floating type floating net cage, reduces the difficulty and cost of design, manufacture and construction, shortens the construction period, reduces the limitation of natural conditions and is simple to maintain.

As shown in fig. 11a-d, the buoyancy of the space truss structured aquaculture net cage 1 is adjusted, in particular as follows, by adjusting the buoyancy of the single or multiple buoyancy-adjustable points at different positions in the aquaculture net cage 1, either synchronously or in a distributed manner.

According to the requirements of the cultivation working conditions, the cultivation net cage 1 can be adjusted in the floating, semi-submerged, bottoming and superficially floating conditions, and the cultivation net cage can be floated as much as possible to facilitate operation during fish collection and net coat replacement or cleaning.

As shown in fig. 11a, in normal use (vertical, i.e. substantially vertical), the operation of the farming box 1 is divided into:

1. a normal full-floating state in which the buoyancy of the farming net cage 1 is greater than the gravity of the farming net cage 1;

2. a semi-submerged operating state in which the buoyancy of the farming net cage 1 is slightly greater than the gravity of the farming net cage 1;

3. a bottoming operation state in which the buoyancy of the farming net cage 1 is less than the gravity of the farming net cage 1;

4. the ultra-floating working state, in which the buoyancy of the aquaculture net cage 1 is much greater than the gravity of the aquaculture net cage 1.

The four working states are specifically applied, the working states can be set to be full-floating or semi-submerged in normal cultivation, the waterline of the cultivation net cage 1 in the normal full-floating state is located on the central maximum diameter line of the buoyancy adjustable node of the truss on the top layer of the cultivation net cage 1, namely, the top layer of the netting is located below an offshore plane, and when the sea condition is good, the cultivation net cage 1 is located at the working position, so that daily cultivation works such as observation, feeding and the like of a cultivation body are facilitated; the semi-submerged working state has the advantages that the water level line of the culture net cage 1 is positioned on the central maximum diameter line of the buoyancy adjustable node of the top layer of the semi-submerged truss of the culture net cage 1, namely, the top layer of the netting is positioned at the semi-submerged depth below the sea level, namely, 6 to 12 meters, so that the impact of stormy waves on the culture net cage 1 is effectively avoided, the stable and safe structure of the culture net cage 1 is ensured, the damage of stormy waves to culture facilities and culture objects can be reduced, and the batch death of cultured fish shoals due to stress reaction is avoided; when the special requirements of stormy waves, ocean currents and water temperature are met, the cultivation net cage 1 can be set to be in a bottom-sitting working state. For example, when the sea surface water temperature is too high in stormy waves, the temperature of the culture water body needs to be reduced, for example, when the Atlantic salmon is cultured in a yellow sea cold water mass in summer. Or the sea water temperature is too low, when the temperature of the breeding water body needs to be increased, such as the situation of winter breeding of the large yellow croaker in the east sea; when the culture net cage 1 is inspected and maintained, the net is replaced, and the cultured fish is put in and harvested, the culture net cage 1 can be set to be in an ultra-floating state, and the operation difficulty can be greatly reduced.

As shown in fig. 11b-d, the adjustment of the draft or bearing capacity of the aquaculture net cage 1 in water is realized; the posture of the culture net cage 1 is adjusted, and the culture net cage comprises any two of a generally vertical state, a generally horizontal state and a rolling state in a vertical plane. The switching can be completed in water completely, and the influence of sea storms is avoided by utilizing the relatively calm ocean current environment under water; the device can also be completed in a normal full-floating working state and an ultra-floating working state, for example, when the seaborne stormy waves are small, and the gravity of the part above the sea surface is more beneficial to being matched with the underwater buoyancy.

As shown in fig. 11b, when the culture net cage 1 is used horizontally (approximately in a horizontal state), besides the same working state and the same state as the normal upright working state, a rolling working state is added, particularly but not limited to an ultra-floating working state, in which the structure of the culture net cage 1 can be all lifted out of the water one by one in the rotation process, which brings great convenience for maintenance of the culture net cage 1, such as cleaning and coating of attachments, replacement of parts, and the like.

As shown in fig. 11c, is a switch between a substantially horizontal state and a substantially vertical state; fig. 11d shows a switch between a substantially horizontal state or a substantially vertical state and a rolled state in a vertical plane.

In deep sea cultivation, the rolling and switching of the posture of the cultivation net cage 1 can enable different surfaces to face upwards and even float out of the water surface in sequence, so that aquatic products in the cultivation net cage 1 are not affected, the cleaning operation of the attachment of the cultivation net cage 1 in rolling and turning and self-falling off of the water surface and timely maintenance on water of the cultivation net cage 1 component are facilitated, the posture is adjusted according to the sun azimuth, the direction of sunshade objects (such as the attachment) of the cultivation net cage 1 and an aquatic product illumination scheme, the light shielding and flow blocking effect of the sunshade objects of the net cage is utilized, the illumination duration, the direction and the control flow rate in the cultivation net cage 1 are independently controlled, the fish stress reaction is avoided, and the aquatic product quality and the yield are improved. The benefits of the active improvement of the cultivation environment created by this are not listed one by one.

As shown in fig. 11d, the method for adjusting the posture of the cultivation net cage 1 comprises the following steps:

s1, determining the direction of posture adjustment and the gravity balance middle longitudinal surface of the culture net cage 1 of the whole space truss structure;

s2, exhausting and feeding water into the buoyancy adjustable point 10 positioned at the front of the posture adjustment direction of the gravity balance middle longitudinal surface, reducing the buoyancy, and exhausting and feeding water into the buoyancy adjustable point 10 positioned at the rear of the posture adjustment direction of the gravity balance middle longitudinal surface, and increasing the buoyancy;

S3, rolling over the culture net cage 1 of the whole space truss structure, and achieving a middle temporary rebalancing state;

s4, repeating the steps S1-S3 until the preset posture is reached.

After the intermediate temporary rebalancing state is reached, in step S4, the direction of the posture adjustment determined again and the gravity balance middle longitudinal plane of the whole aquaculture net cage 1 may be different from those determined previously, for example, fig. 11d shows a roll-over in the vertical plane of the paper, and when 45 ° it may be changed to a roll-over in the vertical plane with an included angle of 45 ° with the paper, and when 90 ° it may be changed to a roll-over in the vertical plane perpendicular to the paper. That is, from the initial state to the final predetermined posture, the intermediate scroll path needs to be planned and designed in advance, and an optimal path needs to be selected among a plurality of possible scroll paths, and then S1 to S4 are performed.

As shown in fig. 17c, the switching between the substantially horizontal state and the substantially vertical state in the collapsed posture is performed.

As shown in fig. 11d, the method for adjusting the posture of the robot comprises the following steps:

That is, from the initial state to the final predetermined posture, the intermediate scroll path needs to be planned and designed in advance, and an optimal path needs to be selected among a plurality of possible scroll paths, and then S2 to S4 are performed.

Further, the buoyancy adjustable node 10 adjusts the buoyancy in a manner of adjusting the mutual proportion of the air intake and exhaust amount and the water intake and exhaust amount in the shell, and the specific scheme is as follows.

As shown in fig. 18, the buoyancy adjustable point 10 includes a housing 101, a central air pipe 102 is disposed in the housing 101, an elastic air bag 103 is disposed between the housing 101 and the central air pipe 102, an air inlet and outlet 104 is disposed on the central air pipe 102, at least one end of the central air pipe 102 is connected with an air source, an air inlet and outlet 105 is disposed on the housing 101 and outside the elastic air bag 103, and the air inlet and outlet 105 can be communicated with an external water body; the shells at two ends of the central air pipe 102 are provided with a connecting flange 106 and a sealing pressing plate 107, which are used for being in sealing connection with truss rods, the upper connecting flange is provided with an air inlet 108 and a corresponding air inlet valve 1081, an air outlet 109 and a corresponding air outlet valve 1091, which are all communicated with the upper end of the central air pipe 102, and the air inlet valve and the air outlet valve are communicated with an air source, such as an air compression device (such as an air pump) or a spherical storage node 10' for storing compressed air; of course, the air inlet and the air outlet, the air inlet valve and the air outlet valve controlled by external signals can be combined into one; the lower connection flange inlet and outlet 105 is correspondingly provided with an inlet and outlet valve 1051 controlled by an external signal, and is preferably also provided with an inlet filter 1010 between the external water body and the internal water body. The air intake and exhaust amount of the elastic air bag 103 is adjusted to adjust the air bag expansion degree, so as to adjust the water intake and exhaust amount between the shell 101 and the elastic air bag 103, and further adjust the buoyancy of the buoyancy adjustable point. During operation, when the inlet valve 1081 and the inlet and outlet valve 1051 are opened simultaneously, compressed gas enters the elastic air bag 103, the air bag expands, the volume is increased, and water with corresponding volume is discharged into external water body from the inlet and outlet valve 1051, so that the buoyancy of the buoyancy adjustable point is increased. Conversely, when the exhaust valve 1091 and the intake and exhaust valve 1051 are simultaneously opened, the gas pressure in the elastic balloon 103 decreases, the balloon contracts, the volume decreases, and a corresponding volume of water enters the buoyancy-adjustable point from the intake and exhaust valve 1051, at which time the buoyancy of the buoyancy-adjustable point increases. During the above adjustment process, if the inlet and outlet valves and the inlet and outlet valve 1051 are closed at the same time, the water-air ratio inside the buoyancy adjustable node will maintain the state when the valve is closed, and the buoyancy of the buoyancy adjustable node is stabilized at a specific value adjusted.

As shown in fig. 19a-c, the buoyancy of the buoyancy node is greatest when all of the interior of the buoyancy adjustable point is gas, and the buoyancy of the buoyancy node is reduced as the gas pressure is reduced and the water of the external body of water gradually enters the interior of the sphere, and the buoyancy of the buoyancy node is minimized when the gas pressure is reduced to the point where the water of the external body of water completely fills the interior of the sphere.

Further, the central air tube 102 serves as an internal reinforcing support structure for the housing 101. Further, each central air pipe 102 in the cultivation net cage is arranged in the main stress direction of the respective casing 101.

Further, the central air pipe 102 is mutually communicated with the hollow truss rod, and the hollow inter-node connecting rod 12 is used as an air supply channel of an air source, so that the air supply device is suitable for the condition that the diameter of the truss rod, the length of an air path, the power of the air source and the like are mutually matched. If the matching condition is not good, further, the air supply and exhaust pipeline between the air source and the central air pipe 102 is arranged by using the hollow space of the connecting rod 12 between the nodes, so that the air supply and exhaust pipeline is well protected in the truss rod, and in the whole manufacturing process of the aquaculture net cage, the air supply and exhaust pipeline is prefabricated in the truss rod for assembly, thereby improving the production efficiency.
