Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, and in particular to a wind and wave resistant gravity cage. Background Technology

[0002] Gravity cages are an important piece of equipment used in deep-sea aquaculture. They rely mainly on buoyancy and gravity to maintain the tension and shape of the netting. They have good flexibility and can move with the waves, adapting to changes in water flow and waves. They are usually made of high-density polyethylene (HDPE) pipes.

[0003] In deep-sea aquaculture environments, wind and waves are common natural phenomena. Strong winds and waves can damage, break, or even lose net cages, resulting in economic losses and the escape of farmed fish. Therefore, a wind and wave resistant gravity net cage is proposed. For example, the prior art Chinese patent announcement number "CN218851637U" discloses a gravity aquaculture net cage structure, including a buoyancy ring pipe, a net cage upper line, a net cage lower line, and a net. The upper line is connected to the buoyancy ring pipe around its four sides by connecting rods. Several support columns are installed on the top of the upper line, and handrails are connected to the top of the support columns. The bottom of the upper line is connected to the net through a zipper. The bottom of the net is connected to the lower line. Several second floats are connected to the lower line, and several first floats are connected to the upper line. The main characteristic of this net cage is its excellent resistance to wind and waves. It mainly relies on buoyancy and the fixation of gravity-embedded counterweights to support the entire cage structure. In the marine environment, it lies vertically in the sea, with the floating frame part floating on the water surface. When a harsh marine environment occurs, it can be submerged below the sea surface to prevent damage, effectively preventing the impact on aquaculture resources caused by changes in the volume of net cage culture.

[0004] In actual operation, the buoys are responsible for providing sufficient buoyancy to keep the cage on the water surface. If the buoys cannot be used in combination, the buoyancy distribution of the cage may be uneven, affecting its stability in the water. Especially in the case of large winds and waves, the cage is more likely to tilt or capsize. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where multiple pontoons cannot be combined, affecting the stability of the net cage in water, and to propose a wave-resistant gravity net cage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a wave-resistant gravity cage, including a net set between a floating frame and a counterweight, characterized in that: the floating frame is fixedly connected to the upper line of the net, and several sets of buoyancy components and anchors are connected to its periphery, each set of buoyancy components has several units, and the multiple buoyancy components are combined and used through connecting parts;

[0008] An adjusting component is provided between the floating frame and the anchorage, and the adjusting component is used to adjust the height of the gabion.

[0009] Furthermore, the buoyancy component is a float, which consists of a pair of semi-cylindrical shells. The pair of shells are fixed together by fasteners, and their closure is used to fix a weight block located inside.

[0010] Furthermore, the connecting part includes a docking protrusion and a fixing protrusion, the docking protrusion and the fixing protrusion being integrally formed on the side of the pontoon, wherein the pontoons on adjacent sides are fixed together by the docking protrusion and the fixing protrusion.

[0011] Furthermore, the end face of the mating protrusion forms an elastic claw through a U-shaped groove. The elastic claw has a locking claw on the side of its free end. The fixed protrusion is provided with a mating groove, and a locking groove is opened on the side of the mating groove. The mating protrusion is located in the mating groove, so that the locking claw engages with the locking groove.

[0012] Furthermore, the adjusting component is a turnbuckle, which includes a pull rod and adjusting rods threaded to both ends of the pull rod. The opposing ends of the pair of adjusting rods have annular portions, and the pair of annular portions are respectively connected to the ropes of the anchor and the floating frame.

[0013] Furthermore, a handrail is fixedly installed on the inner edge of the top of the floating frame, and a walking channel is formed between its outer edge and the handrail. The buoy is fixed to the outer edge of the floating frame by ropes.

[0014] The beneficial effects of this invention's wave-resistant gravity-type net cage are as follows: This invention allows multiple floats to be fixed together via a connecting part. Increasing the number of floats means increasing the total buoyancy, thus improving the net cage's stability in the water and making it less prone to being capsized by waves. This enhances the buoyancy and stability of the netting. Furthermore, the height of the net cage can be adjusted by adjusting the turnbuckles. In situations with large waves, lowering the height of the net cage allows it to be positioned in a calmer water layer, reducing the direct impact of waves on the net cage. This enhances the net cage's wave resistance, ensuring that it is not easily damaged or sunk in severe weather conditions, thereby protecting the safety of aquaculture organisms.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A wave-resistant gravity cage includes a net 3 disposed between a floating frame 1 and a counterweight 2. The floating frame 1 is fixedly connected to the upper rope of the net 3, and several sets of buoyancy components 4 and anchors 7 are also connected to its periphery. Each set of buoyancy components 4 has several components, and multiple buoyancy components 4 are combined and used through connecting parts.

[0022] An adjusting member 5 is provided between the floating frame 1 and the anchor 7, and the adjusting member 5 is used to adjust the height of the cage.

[0023] Furthermore, the buoyancy component 4 is a float 41, which is composed of a pair of semi-cylindrical shells 411. The pair of shells 411 are fixed together by fasteners, and their closing is used to fix the weight block 412 located inside.

[0024] It is worth mentioning that the fastener is a locking bolt, which is used to fix or unlock a pair of housings 411 to facilitate the replacement of weight blocks 412 of different weights. The housing 411 has a groove inside, and the two grooves on both sides close together to form a mounting groove. The weight block 412 is placed in the mounting groove. Furthermore, weight blocks made of materials with different densities have different weights for the same volume. The weight block 412 plays a role in stabilizing the center of gravity of the float 41.

[0025] Furthermore, the connecting part includes a docking protrusion 42 and a fixing protrusion 43, which are integrally formed on the side of the float 41. The floats 41 on adjacent sides are fixed together by the docking protrusion 42 and the fixing protrusion 43.

[0026] More specifically, the end face of the mating protrusion 42 forms an elastic claw 421 through a U-shaped groove. The elastic claw 421 has a locking claw 422 on the side of its free end. The fixing protrusion 43 is provided with a mating groove 431, and a locking groove 432 is provided on the side of the mating groove 431. The mating protrusion 42 is located in the mating groove 431, so that the locking claw 422 engages with the locking groove 432.

[0027] It should be added that the float 41 is preferably made of rubber or plastic material. Such material has good buoyancy and a certain deformation capacity when it has a cavity inside. Therefore, by pressing the claw 422, the elastic claw 421 can be squeezed to deform, thereby enabling the claw 422 to engage or unlock with the slot 432.

[0028] Since the docking protrusion 42 is located within the docking groove 431, there is a certain amount of movement between the docking groove 431 and the docking protrusion 42 to prevent the elastic claw 421 from getting stuck. Alternatively, the elastic claw 421 can be located on both sides of the docking protrusion 42. In this case, the slot 432 is located on both sides of the fixed protrusion 43 and corresponds to the elastic claw 421. By docking left and right or unlocking, the situation of getting stuck can also be avoided.

[0029] The claw 422 is also provided with guide slopes on both sides to reduce friction.

[0030] In general, the adjusting component 5 is a turnbuckle, which includes a pull rod 51 and adjusting rods 52 threaded to both ends of the pull rod 51. The opposite ends of the pair of adjusting rods 52 have annular portions 521, and the pair of annular portions 521 are respectively connected to the ropes of the anchor 7 and the floating frame 1.

[0031] Finally, a handrail 6 is fixedly installed on the inner edge of the top of the float 1, and a walking channel is formed between the outer edge of the float 1 and the handrail 6. The float 41 is fixed to the outer edge of the float 1 by ropes.

[0032] Specifically, by adjusting the height of the net cage using the turnbuckles, the net cage can be placed in a calmer water layer, thereby reducing the direct impact of wind and waves on the net cage. Furthermore, the walking channel facilitates the assembly or disassembly of the pontoons 41.

[0033] Working method: When it is necessary to improve the wind and wave resistance of the cage, the staff will combine several floats 41 together through the walking passage;

[0034] The adjacent floats 41 are fixed together by the docking protrusion 42 and the fixing protrusion 43. In addition, the staff can also adjust the height of the net cage by diving to the bottom of the water and using the pull rod 51 and the adjusting rod 52 to improve the stability of the net cage and also to lower the height of the net cage.

[0035] When unlocking the float 41, pressing the claw 422 causes the elastic claw 421 to deform, and then the docking protrusion 42 disengages from the docking groove 431, and the floats 41 separate.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
