Floating structure for aquaculture with air pipes for buoyancy reinforcement {Floating structure for aquaculture.}

The present invention relates to a floating structure installed in an offshore aquaculture, and one or more reinforcing frames are installed inside the buoyancy pipe that provides buoyancy to the structure, so that the structure remains stable even in a sea with high waves, and at least one air pipe is It relates to a floating structure for aquaculture farm that is installed through a connection bracket to increase reinforcement and buoyancy while working in a balanced manner during offshore work.

In general, for cages or berthing facilities for ships installed in waters such as coastal waters or lakes, moorings are installed by tying buoyancy materials such as logs or styrofoam into a certain shape, and then a scaffolding on which people can move. On the other hand, it is necessary to install a net for a cage or a net rope or a buffer bumper necessary for the berth of the ship.

In general, a floating body is a term that collectively refers to an object floating on the surface or in the middle of a liquid by receiving buoyancy, and is classified into various forms depending on the purpose of use. These floats are used in the manufacture of floating structures such as floating piers, ship aprons, and cage farms. In particular, due to its excellent efficiency, the demand for water piers is gradually increasing.

In the past, mooring structures such as cages or berth facilities were mostly installed using buoyancy materials such as logs or styrofoam. As described above, the wooden structural material has an advantage of excellent strength, but only slight damage even with a large impact. However, such a mooring structure requires a lot of manpower in the installation process, is vulnerable to corrosion to seawater, deteriorates the life and safety of the mooring structure, and has a problem that debris from the buoyant material pollutes the sea or lake.

The floating structure is a structure that can mount people and expensive installations on the water.Since it is always exposed to seawater including salt or freshwater environments where ice pressure acts, and environments such as typhoons, floods, and waves, structural stability and durability are very important. In addition, in terms of functionality, not only should it be possible to combine it in various sizes and shapes, but it should also protect the facility safely and allow easy maintenance.

Recently, as shown in FIG. 1, it is possible to manufacture in various sizes and shapes, and are extruded and manufactured. The floating structure shown in Figure 1 is formed of a polymer compound such as polyethylene, a scaffold support having a semicircular groove portion formed on the lower surface thereof; A coupling plate in which a semicircular groove portion corresponding to the groove portion of the footrest support is formed; One or more fastening bolts for fastening the footrest support and the coupling plate are installed; It consists of a scaffold support and a pipe-shaped buoyancy body inserted into the grooves of each of the coupling plates. However, in the above structure, it is difficult to firmly maintain the supporting state of the buoyant body because the fastening bolt itself is easily damaged or loose.

Accordingly, as for the scaffold support, as published in Korean Utility Model Publication No. 20-2010-0005101, a device has been developed that provides a pipe-shaped buoyancy body and scaffold support in a bracket structure, but the current flow is strong or the wave is large. Installation on the shore can be very risky because the durability of the buoyancy pipe is weakened in proportion to the size of the structure.

In Korean Patent Application Publication No. 20-2010-0005101, coupling protrusions and coupling holes are formed on the left and right sides of the support frame, which is the assembly surface between the connection brackets, and handrail posts are assembled inside the upper two sides of the support frame. By forming a connecting pipe for the mooring structure, the installation work of the mooring structure using the connecting bracket can be performed more easily and accurately, while the facility strength of the mooring structure based on the connecting bracket can be greatly improved. In addition to providing a mooring structure that can be safely used for a long period of time even under harsh environmental conditions such as wave, etc., the rigid installation of the handrail post and the safety of the handrail based on this is further improved. A connection bracket for mooring structures is posted so that it can be improved. In Korean Patent No. 10-1639202, an air inlet for injecting air into the inner air receiving space of the buoyancy body is formed to protrude in the inner direction of the air receiving space to prevent external exposure, thereby causing cracks in the air inlet. It is posted on floating buoyancy bodies that can prevent loss of buoyancy function due to damage or damage. Japanese Patent Application Laid-Open No. 2000-064223 provides the required freeboard height through economically manufacturing period reduction and easily through high dimensional accuracy. Solution: The side plate 12 of the reinforced concrete deck is provided vertically along each side end of the lower plate 11 of the reinforced concrete deck, and the edge face 13 of the reinforced concrete deck is vertically along each end of the lower plate 11. It is provided, and thereby discloses a structure for a fluid structure and a method of manufacturing the same, each forming an outer frame. In Korean Patent No. 10-0823140, a floating block 10 in the shape of a housing is coupled by a coupling member 20, and a circular shape so that the coupling member 20 is fitted on the coupling surface of the floating block 10. The coupling hole 102 is formed, and the coupling member 20 is formed of an air tube, and when air is injected into the air inlet 201 formed on one side of the coupling member 20, a concave portion 202 in the center Is formed, and convex portions 203 and 203' are formed on both sides of the concave portion 202 so that the convex portions 203 and 203' are inserted into and coupled to the coupling hole 102 of the floating block. , Since a plurality of floating blocks 10 are coupled by the coupling member 20, the installation and disassembly work of the floating structure is easy, and the floating structure using an air tube is provided to maintain a stable shape without being disturbed. About.

One or more reinforcing frames are installed inside the buoyancy pipe of the present invention to keep the structure stable even in the sea with high winds, and one or more air pipes are installed through the connection bracket to adjust the buoyancy and tension the air pipe to load the sea To provide a floating structure for aquaculture that can float on the sea in a balanced manner.

In order to achieve the above object, the floating structure for aquaculture farm according to an embodiment of the present invention is installed with one or more buoyancy pipes spaced apart at regular intervals in the horizontal direction; At least one slat-shaped support frame is intersected at regular intervals in the horizontal and vertical directions to form a plurality of rectangular fitting holes, and a connecting bracket is installed at the lower part to form a fitting groove to fit and fix the buoyancy pipe; It may be made by installing a working plate providing a space on the sea above the connection bracket.

In addition, the buoyancy pipe is a pipe frame having a pipe structure with an empty inside of a predetermined length, and an end frame having an inclined downwardly formed at the openings at both ends of the pipe frame, and can be installed corresponding to the space inside the pipe frame. It may be made by installing one or more reinforcing frames in size.

The reinforcing frame may be a reinforcing frame having a diameter that can be accommodated in the pipe frame in a circular shape, and one or more reinforcing ribs installed so as to be supported from the center of the reinforcing frame toward the inner surface. An auxiliary connection bracket may be installed at the bottom of the bracket, and a fitting groove may be installed at a lower portion of the auxiliary connection bracket to fix the auxiliary buoyancy pipe, so that an auxiliary buoyancy pipe may be installed.

One side surface of the end frame forming the buoyancy pipe of the present invention has the effect of minimizing the resistance of seawater and minimizing interference with waves when moving the structure by forming an inclined downwardly. One or more reinforcing frames installed inside the buoyancy pipe may prevent the pipe frame forming the length of the buoyancy pipe from being damaged or bent by an external environment. In addition, since it is easy to increase or decrease the buoyancy, there is an effect of maintaining a stable sense of structure even with an increase in loading capacity, while maintaining a constant balance on the sea.

1 shows a conventional floating structure. The floating structure shown in FIG. 1 is formed of a polymer compound such as polyethylene and a scaffold support having a semicircular groove formed on a lower surface thereof; A coupling plate in which a semicircular groove portion corresponding to the groove portion of the footrest support is formed; One or more fastening bolts for fastening the footrest support and the coupling plate are installed; It consists of a scaffold support and a pipe-shaped buoyancy body inserted into the grooves of each of the coupling plates.

However, the above structure has a problem that it is difficult to maintain the support state of the buoyant body as it is easy to damage or loosen the fastening bolt itself, and if it is installed in an area where there is a strong wave or current, the buoyant body in the shape of a pipe may be damaged. There is a problem. Hereinafter, the accompanying drawings related to the floating structure for aquaculture of the present invention will be described in detail.

Figure 2 shows a perspective view of the floating structure for aquaculture of the present invention. One or more buoyancy pipes 300 are installed at regular intervals in the horizontal direction; At least one slat-shaped support frame is intersected at regular intervals in the horizontal and vertical directions to form a plurality of rectangular fitting holes, and a connecting bracket 200 is installed in the lower part of which a fitting groove is formed to fit and fix the buoyancy pipe. ; A working plate 100 providing space on the sea may be installed on the upper part of the connection bracket.

The floating structure for the farm is made of polyethylene (PE; polyethylene or HDPE; high density polyethylene). Such a material has an advantage of being light in weight and having a lower density than water, so that it floats well in water, has excellent durability, low moisture absorption, and high corrosion resistance to seawater. In addition, it can be crushed and reused 100% to prevent the generation of marine debris.

The working plate 100 is a space in which a user's work is performed or can be loaded, and may be formed of a scaffolding structure that is usually installed on a floating structure. A handrail may be formed on the upper part of the working plate so that the user can walk safely, and may be formed in various known shapes within a range that can ensure safety.

Figure 3 shows the buoyancy pipe of the present invention. The buoyancy pipe 300 of the present invention includes a pipe frame 302 having a pipe structure with an empty inside of a predetermined length, and an end frame 301 having an inclined downwardly at both end openings of the pipe frame. It is fitted and fixed to the opening, and at least one reinforcing frame 303 may be installed inside the pipe frame.

The pipe frame 302 is empty and provides buoyancy to the floating structure for aquaculture farm of the present invention. It is appropriate that the pipe frame of the present invention has a circular cross section, which is to minimize resistance to ocean currents and to prevent the structure from being worn. The pipe frame forming the buoyancy pipe is sealed at both ends and maintains a constant air pressure inside, so that the shape of the frame can be kept constant in its original state.

When the buoyant body is manufactured on land, the air pressure tends to expand according to the land temperature, and when it is installed in the actual sea site, the air inside the buoyant body decreases due to the seawater temperature and the air is contracted, so it is manufactured and maintained at atmospheric pressure + 0.5 atm. It is appropriate to do.

One side of the end frame 301 may have a downwardly inclined surface, and the other side may be formed with an insertion portion capable of inserting and fixing the end portion of the pipe frame into the inside. When the structure is moved on the water, the inclined surface minimizes interference due to waves to facilitate the movement operation, and when installed on the sea, it is possible to minimize shaking by dissipating the water pressure of seawater.

As the length of the pipe frame increases and the diameter of the cross section increases, durability against the external environment decreases. In addition, as the load on the structure increases, an increase in buoyancy is required, and durability that can withstand the pressure of the load through the frame must be improved.

To compensate for this, the buoyancy pipe 300 may have a thicker thickness compared to the diameter of the buoyancy pipe 300, but in this case, it may cause a decrease in buoyancy and an increase in manufacturing cost due to an increase in material cost. A reinforcing frame is installed. The reinforcing frame 303 has a reinforcing frame having a diameter that can be accommodated in the pipe frame, and reinforcing ribs capable of supporting the reinforcing frame are formed inside the reinforcing frame to support the force applied to the side surface. Accordingly, it is possible to prevent the pipe frame from being bent or damaged.

Figure 4 shows an embodiment of the buoyancy pipe according to the present invention. Typically, floating structures have to withstand a weight of about 150 tons or more, such as barges used in aquaculture farms. At this time, a lot of load may be applied, so that the buoyancy requirement of the structure may increase. Accordingly, Embodiment 1 according to the present invention can compensate for insufficient buoyancy by installing the auxiliary buoyancy pipe 304 under the connection bracket. In general, when an auxiliary buoyancy pipe is installed, an auxiliary connection bracket 201 is installed under the connection bracket, and the auxiliary connection bracket 201 is formed in a structure capable of inserting and fixing the upper side of the auxiliary buoyancy pipe.

5 shows a connection bracket 200 of the present invention. In the connection bracket 200 of the present invention, at least one plate-shaped support frame is cross-connected horizontally and vertically to form a square or rectangular fitting hole. The connection bracket 200 is installed perpendicular to the installation direction of the buoyancy pipe, and a fitting groove capable of fitting and fixing the upper portion of the buoyancy pipe may be formed at the lower portion. The connection bracket can be fixed to one or more buoyancy pipes while at the same time fixing one or more buoyancy pipes to improve the stability of the buoyancy pipe. In addition, the connection bracket is easy to install by fitting and inserting and fixing, and the strength of the facility is improved, so it can be installed for a long time even under poor environmental conditions such as strong winds and waves.

Figure 6 shows an embodiment of the floating structure for aquaculture of the present invention, Figure 7 shows an air pipe according to the embodiment. When a floating structure for aquaculture is used as an offshore workbench, it is necessary to maintain the level of the floating structure because the load can be concentrated only on one part of the scaffold, and in this case it is difficult to maintain and support horizontally at the sea level. have.

The air pipe 400 of the present invention is inserted into a fitting hole of a square or rectangular structure formed by crossing one or more horizontal and vertical support frames of the connection bracket. The air pipe has a pipe fixing part 401 having a diameter corresponding to the inside of the fitting hole, and a hollow part 402 to which an external pipe 403 is inserted and fixed on the side of the pipe fixing part, and penetrates the hollow part. An outer pipe 403 to be fitted and fixed, and an inner pipe 404 capable of injecting and discharging air may be formed inside the outer pipe.

The outer pipe has a circular pipe structure formed of a polyethylene material and may have a diameter that can be fixed through the hollow portion of the pipe fixing part. The outer pipe and the inner pipe installed therein are preferably formed in a circular shape, but may be formed in a polygonal shape formed by a fitting hole of the connection bracket.

The inner pipe 404 installed inside the outer pipe is formed of a material having excellent elasticity such as rubber or vinyl, and air is injected into the inner pipe. When the atmospheric pressure is set to 0, the pressure of air injected into the inner pipe is appropriate to be injected at a maximum of 50 to 90 psi. As the air pressure injected into the interior increases, the inner pipe expands primarily and the inner pipe fills the space inside the outer pipe. When a certain pressure is exceeded, the inner pipe expands and supports the inside of the outer pipe with elasticity, so the outer pipe maintains a straight tension and supports the connection bracket supported by the outer pipe in the horizontal direction.

In particular, when the air pipe is reinforced in a part where the load is applied, it prevents the phenomenon that the floating structure suffers from fatigue due to the bending of the floating structure according to the height difference between the swell and the swell while waves or swells pass. can do. In addition, by injecting air into the inner pipe to have a constant pressure, it is possible to easily balance the entire pipe while supplying buoyancy to the structure, and by connecting one or more connecting brackets, stability of the structure may be provided. In addition, since the air pressure is adjusted according to the injection and discharge of air, there is an effect of flexibly coping with the movement of the structure or waves and waves.

Since the structure installed on the sea receives continuous force from waves and ocean currents, when the outer pipe is formed in a circular pipe shape, when it is fitted and fixed in a fitting hole having a square or rectangular shape, it may be worn and shortened its lifespan. Accordingly, the pipe fixing portion is formed to have a size and diameter corresponding to the fitting hole, so that the external pipe can be more stably fixed even when the current shakes.

8 shows an embodiment of an air pipe according to the present invention. In the above embodiment, the inner pipe is installed at the inner center of the outer pipe, and one or more inner reinforcing pipes 405 may be formed in the upper, lower, left, and right directions around the inner pipe. The internal reinforcing pipe is made of metal rod material such as stainless steel wire or piano core, and it reinforces the horizontal tension together with the internal pipe, so that the external pipe is tensioned in the horizontal direction to maintain the level of the floating structure.

By providing a floating structure for aquaculture that has improved long-term installation and durability, it is possible to increase the utilization of marine space and to provide an eco-friendly device that can reduce marine pollution caused by the separation and dismantling of the existing aging structure, and the life of the device is improved. It is possible to use industrially because it can reduce the cost burden of fishermen.
