Description

Assembling type Buoy}

The present invention relates to an assembled float.

In general, floats are floats on the surface of the water. Also called buoy or buoy. The floats are used in positions to direct the course to help the ship navigate safely. Buoys are also used to warn of the presence of nautical hazards, such as reefs and sinking ships. In addition, floats are also used to indicate the location of objects in water, such as fishing gear and anchors. In addition, the ball is used to fix the net installed in a certain range to fish, waste and algae.

These buoys are buoyant to float on the sea, and are fixed to the bottom or bottom of the seabed by means of an instrument that can be anchored to it. Dangling instruments include chains and wires.

Flags may be installed on the floats to identify them. In addition, the sub-ball may be provided with a variety of transmission and reception objects that can be identified by an electronic signal, and may be provided with an equalizing device that emits light so that it can be identified at night.

The general sphere is made of a foamed resin material obtained by foam molding a synthetic resin. The foamed resin material generates voids due to the gas introduced during the foaming of the synthetic resin. The foamed resin with voids thus generated has a buoyancy which can float on water. These foamed resins are buoyant due to internal voids and do not require a space for air storage. In addition, even if the foamed resin is partially damaged, there is an advantage that the buoyancy is generated in the remaining portion does not buried in the water.

However, the foamed resin is weak in strength because voids are formed therein. In other words, when the external impact of the foamed resin is transmitted, the impact propagates between the pores of the foamed resin and is easily broken. Therefore, the ball | bowl using the foamed resin with weak strength is short in time of replacement.

In addition, a buoy formed of a foamed resin floating in the sea is partially broken by waves. The foamed resin has voids in the interior, so that the binding force between internal tissues is poor. As a result, the waves hitting the float side continuously erode the foamed resin having a weak binding force. Foamed resins that fall off by erosion pollute the sea. In addition, the erosion-rich buoyancy is reduced buoyancy can not float in the water. Therefore, the replacement should be frequent.

In recent years, the conventional mouth is made of a synthetic resin material in which air is injected into the interior using a blow molding method. The conventional mouthpiece is manufactured integrally with the synthetic resin material in the state in which air is injected by the blow molding machine. The conventional buoys manufactured integrally have buoyancy by air filled therein. Compared with the foamed resin material, the conventional ball has a strong strength and does not cause erosion, and thus has a long service life.

However, since the conventional floats are formed integrally, it is difficult to have great buoyancy. In other words, the buckle should be made large so as to have an air-filled area for the required buoyancy as it is manufactured integrally. Accordingly, the manufacturing cost is increased due to the expansion of the blow molding machine.

In addition, conventional floats have been difficult to produce to increase the volume in order to increase buoyancy. In order to produce a volume-enhanced float, a heated synthetic resin material is supplied to the blow molding machine so as to deform the shape. In this way, by injecting air into the interior of the synthetic resin material supplied to the blow molding machine is made in the air filled state inside. At this time, when the volume produced in the mouth increases, it is difficult to maintain the temperature of the synthetic resin material as a whole during air filling. As a result, the heated synthetic resin material is lowered in part temperature, and is fixed at the lowered temperature part. That is, the synthetic resin material supplied to the blow molding machine was hardened in the form where the temperature was lowered or stuck to the molding machine, so that it was difficult to be processed in the correct form.

In addition, the conventional floats have to be made of a large weight of the synthetic resin material so that the volume is enlarged in order to increase the buoyancy, it was difficult to handle the synthetic resin material molded in the heated state. That is, it was difficult to blow a large amount of synthetic resin material by blowing air in the blow molding machine while maintaining a constant temperature so that the shape is deformed. In order to enlarge the volume, air is blown with a heavy-weight synthetic resin material supplied. At this time, air must be supplied until a large volume is reached quickly so that deformation of the mouth can be minimized. Accordingly, when the volume of the mouth and the weight of the synthetic resin material are increased, a large amount of high pressure compressed air is needed at a time, and the size of the inlet for introducing the same must be large. There is a limit to the supply amount of compressed air and thus the size of the inlet port through which air is introduced. In other words, if the compressed air is temporarily supplied excessively, the volume is not constant to increase and the thickness of the mouth is changed. Also, if the inlet is too large, the sealing operation cannot be performed after the air is filled. Therefore, the conventional floats cannot be made larger than a predetermined volume, so that it is difficult to increase buoyancy.

In addition, the conventional floats are manufactured integrally with the air filled therein, so that the buoyancy is temporarily lost when the internal air flows due to some damage. That is, there is a problem in that the air filled in the interior is temporarily discharged to the damaged portion, and water is introduced into the outside by the difference in the discharged air pressure to lose buoyancy.

The problem to be solved by the present invention is that the plurality of divided unit buoyancy body is formed according to the shape of the buoys consisting of a single ball, the molding cost is reduced, even if one of the divided unit buoyancy is broken to reduce the buoyancy remaining Floating as a buoyancy body can be replaced to improve the stability, it is possible to increase the volume of the float according to the degree of division, to provide an assembly-type float that can be produced according to the buoyancy desired by the user.

1 to 3, the assembled buoy 100 according to an embodiment of the present invention includes a buoyancy part 110 and a fixing part 120.

The buoyancy unit 110 includes a unit body 111 and a coupling body 113 divided into a plurality according to the shape of the buoy 100. The unit body 111 is divided into a plurality of divided so as to have the shape of the float 100 when assembled. The unit body 111 is formed in plural so that the divided inner surfaces come into contact with each other to form the buoy 100. An air layer 112 is formed inside the unit body 111. The air layer 112 is filled with air. The unit body 111 has an air layer 112 filled with air therein, and has a buoyancy to float on water. That is, the unit body 111 divided into a plurality has an air layer 112 inside each, the unit body 111 itself becomes a buoyancy body. The unit body 111 is a buoyancy body in which the air layer 112 is formed, and the divided objects are assembled into one to form the buoy 100.

Coupling body 113 is formed at the upper and lower ends of the inner surface of the divided unit body 111 is assembled. Coupling body 113 is protruded in a direction facing each other at the upper and lower ends of the inner surface of the plurality of unit body (111). When the plurality of unit bodies 111 are assembled, the coupling bodies 113 formed at the upper and lower ends, respectively, overlap each other. The coupling body 113 has a through hole 114 is formed therethrough. The coupling holes 114 are positioned such that the coupling holes 114 formed when the coupling bodies 113 overlap each other communicate with each other.

Coupling body 113 is provided integrally with the unit body (111). The coupling body 113 and the unit body 111 is made of synthetic resin.

The synthetic resins mentioned above are polyethylene (LDPE & HDPE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyester (PET), styrene acrylonitrile butadiene (ABS) resin and nylon (PA) and a group selected by any one or a mixture of two or more thereof. That is, it may be selected and used from the above-described synthetic resin group according to the use purpose and the installation place of the float 100.

In addition, the synthetic resin may be a degradable plastic.

Synthetic resin is a kind of high molecular compound and does not rot. When an incorruptible resin is thrown into the ocean, it destroys the food chain of fish, algae, and seaweed. In addition, when the resin is embedded in the ground, polluting the soil by preventing smooth air communication. In order to solve this pollution problem, degradable plastics that have been decomposed in a natural state have been developed. Degradable plastics may be classified into biodegradable plastics that are decomposed into microorganisms and photodegradable plastics that are decomposed by ultraviolet rays. Therefore, after a predetermined period of time, the unit body 111 and the coupling body 113 are integrally manufactured with degradable plastic that is naturally decomposed, thereby minimizing environmental destruction after disposal.

In addition, the unit body 111 and the coupling body 113 formed integrally may be molded by blow molding. Accordingly, the blow molding is determined in the shape and size of the unit body 111 is divided into a plurality of shape depending on the shape of the float 100 to be molded. A blow molding machine that can be molded according to a predetermined shape and size is adopted, and a mold is installed accordingly. The inside of the provided mold is supplied with a synthetic resin heated to a temperature at which the shape can be deformed. After the synthetic resin is supplied, air is injected to form the air layer 112. At this time, the air is injected to the position where the coupling body 113 is formed to protrude in the outward direction of the unit body 111 is formed. When the air is injected, the heated synthetic resin is expanded to form the unit body 111 having the air layer 112 formed therein by a mold. When the molding of the unit body 111 is finished, the coupling body 113 is formed by closing the air layer 112 into which the air is injected and protrudingly bonding the air injection portion outward. Accordingly, the unit body 111 and the coupling body 113 are integrally provided with an air layer 112 formed therein, and are blow-molded to form a coupling body 113 where the air injection position is joined and protruded. Can be made.

Aliphatic copolymers are mixed with polyesters to increase cold resistance. The thermal properties of the polyester remain undeformed at temperatures from -60 ° C to + 150 ° C. However, in extreme climates and glacier topography, sea temperatures can drop below -60 ° C. Thus, in order to prevent deformation of the float 100, the aliphatic copolymer may be mixed with polyester, or the cold resistance strength may be increased by using a synthetic resin containing an aliphatic copolymer in the preparation of the polyester. Therefore, deformation of the float 100 due to the temperature decrease can be prevented and the life can be increased.

Here, in the present specification, for convenience of description, the unit body 111 and the coupling body 113 are integrally molded with the air layer 112 by blow molding. The unit body 111 and the coupling body 113 includes all molding methods that may have an air layer 112 therein.
