Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to an aquaculture cage. Background Technology

[0002] The practice of setting up giant net cages in the ocean to raise fish, shrimp, and other marine life has been widely adopted. However, existing net cages are primarily composed of numerous trusses, resulting in a complex structure, high material consumption, and consequently, high costs. Furthermore, the connections between the trusses are rigid, and the net cages are secured primarily by the cage body connected to several steel wire ropes, each anchored to a stake. This makes the net cages less adaptable and less resistant to wind and waves, unable to withstand the impact of large waves. When large waves occur, the net cages shake and collide, and the ropes facing the wind may break under the impact, causing the cages to overturn and become damaged, crushing the aquatic products and severely impacting the survival of the organisms inside. Damage to the net cages can also cause injury, death, or escape of the farmed aquatic products, resulting in economic losses for farmers.

[0003] Therefore, we have made improvements to this and proposed an aquaculture cage. Summary of the Invention

[0004] The purpose of this invention is to provide an aquaculture cage to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, the present invention provides an aquaculture cage, comprising an aquaculture cage, a connecting frame fixedly connected to the upper end of the aquaculture cage, a floating platform installed above the connecting frame, second connecting ropes connected to all four sides of the bottom of the aquaculture cage, a first connecting rope connected to the outer end of the connecting frame, and a buffer device for fixed connection connected between the first connecting rope and the second connecting rope.

[0006] As a further embodiment of the present invention, the aquaculture cage includes a net, which is a corrugated pleated cylindrical shape, and each of the four corners of the net is connected to a lifting lug, which is fixedly connected to a second connecting rope.

[0007] As a further embodiment of the present invention, the floating platform includes four L-shaped steel frames, which are spliced ​​diagonally to form a cross shape. A connecting hole is provided in the middle of the steel frame, and a bolt is fixedly installed inside the connecting hole. A cross-shaped float plate is connected to the bottom of the bolt, and the bottom of the bolt is fixedly installed on the connecting frame. A fixing sleeve is installed at both ends of the steel frame, and a float ball is fixedly installed inside the fixing sleeve.

[0008] As a further embodiment of the present invention, the connecting frame includes a guide plate and four sets of connecting rods. The connecting rods are fixedly sewn to the four sides of the upper edge of the mesh. Each set of connecting rods has a first folding rod and a second folding rod at its upper end. A screw is fixedly connected to the upper end face of the connecting rod. The connecting rod, the first folding rod, and the second folding rod are all fixedly connected by the screw. A second connecting block is rotatably connected to the middle of the first folding rod and the second folding rod. A rope is connected to one end of the inner side of the second connecting block. The rope passes around the guide plate and is fixedly connected to the floating platform. A hinge hole is opened at the end of the first folding rod away from the second connecting block and the end of the second folding rod away from the second connecting block. A first connecting block is installed inside the hinge hole. There are four first connecting blocks and four second connecting blocks. The four first connecting blocks and the four second connecting blocks form a closed loop connection between all the first folding rods and the second folding rods on the four sets of connecting rods.

[0009] As a further embodiment of the present invention, the guide plate includes a base plate, four guide rollers are fixedly connected to the upper end of the base plate, and four vertical positioning holes are opened in the middle of the base plate, the positioning holes being threadedly connected to bolts.

[0010] As a further embodiment of the present invention, the fixed connection buffer device includes a connecting buffer mechanism, the connecting buffer mechanism includes a rope ring and a fixing plate, a guide rod is fixedly connected to the bottom end of the rope ring, a sleeve is connected to the upper end of the fixing plate, a piston disc is fixedly connected to the bottom end of the guide rod, the piston disc is slidably installed inside the sleeve, and a plurality of buffer components are also sleeved on the guide rod, the buffer components are installed inside the sleeve near the rope ring and between the piston disc.

[0011] As a further embodiment of the present invention, the number of buffer components is not less than four.

[0012] As a further embodiment of the present invention, the buffer assembly includes a first connecting piece and a second connecting piece, with a spring fixedly connected between the first connecting piece and the second connecting piece. The first connecting piece, the second connecting piece, and the spring are all sleeved on the cylindrical surface of the guide rod. Four first connecting rods are connected to the first connecting piece, and four second connecting rods are connected to the second connecting piece. The other end of the first connecting rod is hinged to the other end of the second connecting rod.

[0013] The aquaculture cage provided by this invention has the following beneficial effects:

[0014] 1. By tightening the four corners of the bottom of the aquaculture net cage with a second connecting rope, the net cage is shaped and prevented from swaying under the impact of waves, which would severely affect the normal survival of the organisms inside. At the same time, when the net cage is subjected to large waves and a large drop in water level, a fixed foldable connecting frame is installed at the upper end of the aquaculture net cage to prevent it from overturning. The upper opening of the aquaculture net cage closes and sinks to the seabed, separating it from the waves and preventing damage to the aquaculture net cage and escape of farmed fish. This reduces losses in aquaculture, decreases the frequency of replacing aquaculture net cages, and is beneficial to the development of aquaculture.

[0015] 2. By installing fixed connection buffer devices around the bottom and top of the aquaculture net cage, and by setting multiple compressible and deformable buffer components in the middle of the sleeve and piston plate, when the first or second connecting rope connected to the connecting buffer mechanism is subjected to large wind and waves, a few ropes facing the wind direction will buffer the impact force through the deformation of the buffer components, preventing the ropes from being pulled apart or broken.

Detailed Implementation

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] like Figures 1-11As shown, this embodiment proposes an aquaculture cage, including an aquaculture cage 1. A connecting frame 3 is fixedly connected to the upper end of the aquaculture cage 1. A floating platform 2 is installed above the connecting frame 3. Second connecting ropes 5 are connected to all four sides of the bottom of the aquaculture cage 1. A first connecting rope 4 is connected to the outer end of the connecting frame 3. The first connecting rope 4 is threaded through the bottom partition of the floating platform 2, so that the connecting frame 3 can be unfolded and positioned on the bottom surface of the floating platform 2 under the traction of the first connecting rope 4, making the upper opening of the aquaculture cage 1 wide open, which is convenient for aquaculture production. A fixed connection buffer device is connected between the first connecting rope 4 and the second connecting rope 5. The fixed connection buffer device buffers the upper and lower ends of the aquaculture cage 1, ensuring the overall outline and shape of the aquaculture cage 1, and preventing the deformation of the aquaculture cage 1 by wind and waves from affecting the growth of aquatic products in the water.

[0031] The aquaculture cage 1 includes a net 11, which is a corrugated pleated cylindrical shape. Each of the four corners of the net 11 is connected to a lifting lug 12, which is fixedly connected to a second connecting rope 5. The pleated shape of the net 11 facilitates the raising and lowering deformation of the aquaculture cage 1 in the water. Each pleat at the four corners of the net 11 is provided with a lifting lug 12. In other words, multiple second connecting ropes 5 can be pulled at the four corners of the net 11 at the same time to fix the net 11 in shape and prevent the net 11 from swaying with the water and rubbing against the aquatic products in the water.

[0032] The floating platform 2 includes four L-shaped steel frames 21, which are joined diagonally to form a cross shape. A connecting hole 22 is provided in the middle of each steel frame 21, and a bolt 23 is fixedly installed inside the connecting hole 22. A cross-shaped float plate 24 is connected to the bottom of each bolt 23, and the bottom of the bolt 23 is fixedly installed on a connecting frame 3. Fixing sleeves 25 are installed at both ends of each steel frame 21, and float balls 26 are fixedly installed inside each fixing sleeve 25. The steel frame 21 floats on the water surface via the float plates 24 and float balls 26, facilitating the positioning and installation of the aquaculture cage 1. Furthermore, the steel frame 21 being positioned on the water surface facilitates the movement of personnel. The floating platform 23 facilitates observation and maintenance of the aquaculture cage 1. Bolt 23 connects the steel frame 21 to the connecting frame 3. When the wind and waves are large, bolt 23 comes out from the inside of the connecting frame 3, causing the connecting frame 3 to lose the fixation of the floating platform 2. The connecting frame 3 and the aquaculture cage 1 sink to the seabed, and are only flexibly connected to the steel frame 21 by rope 38. This allows the aquaculture cage 1 to avoid the wind and waves on the sea surface, ensuring the integrity of the aquaculture cage 1 and the aquatic products inside, and reducing losses for farmers. The upper end of the rope 38 can be connected and fixed by a winch to control the sinking distance of the aquaculture cage 1, and also facilitates the subsequent pulling of the aquaculture cage 1 back up.

[0033] The connecting frame 3 includes a guide plate 39 and four sets of connecting rods 31. The connecting rods 31 are fixedly sewn to the four sides of the upper edge of the mesh 11. Each set of connecting rods 31 has a first folding rod 32 and a second folding rod 33 at its upper end. A screw 34 is fixedly connected to the upper end face of the connecting rod 31. The connecting rods 31 and the first folding rod 32, the connecting rods 31 and the second folding rod 33 are all fixedly connected by the screw 34. A second connecting block 37 is rotatably connected between the middle of the first folding rod 32 and the second folding rod 33. A rope 38 is connected to one end of the inner side of the second connecting block 37. The rope 38 passes around the guide plate 39 and is fixedly connected to the floating platform 2. A hinge hole 35 is opened at the end of the first folding rod 32 away from the second connecting block 37 and the end of the second folding rod 33 away from the second connecting block 37. A first connecting block 36 is installed inside the hinge hole 35. There are four connecting blocks 36 and four connecting blocks 37. The four first connecting blocks 36 and the four second connecting blocks 37 form a closed loop connection between all the first folding rods 32 and the second folding rods 33 on the four sets of connecting rods 31. The connecting rods 31 are woven and fixed to the aquaculture cage 1 as a whole. The upper end of the connecting rods 31 is fixed to the first folding rods 32 and the second folding rods 33 by screws 34. The second folding rods 33 and the first folding rods 32 are connected by the second connecting blocks 37 and the first connecting blocks 36. When the second connecting blocks 37 are subjected to the tension of the ropes 38, they will drag the first folding rods 32 and the second folding rods 33 along the first connecting blocks 36 and the second connecting blocks 37, and finally close them in a cross shape, sealing the upper end of the aquaculture cage 1. This prevents the aquaculture cage 1 from sinking at the bottom of the water body and from escaping from the top opening when it floats with the waves, thus reducing the losses of aquaculture farmers.

[0034] The guide plate 39 includes a base plate 391. Four guide rollers 392 are fixedly connected to the upper end of the base plate 391. Four vertical positioning holes 393 are opened in the middle of the base plate 391. The positioning holes 393 are threadedly connected to the bolts 23. The guide plate 39 is installed directly below the floating platform 2, so that the rope 38 can pull the second connecting block 37 towards the middle, so that the connecting frame 3 can shrink and deform towards the middle when deformed, thus completing the closure of the top of the aquaculture cage 1.

[0035] The fixed connection buffer device includes a connecting buffer mechanism 6, which includes a rope ring 61 and a fixing plate 65. A guide rod 62 is fixedly connected to the bottom end of the rope ring 61, and a sleeve 64 is connected to the upper end of the fixing plate 65. A piston disc 63 is fixedly connected to the bottom end of the guide rod 62. The piston disc 63 is slidably installed inside the sleeve 64, and multiple buffer components 66 are also sleeved on the guide rod 62. The buffer components 66 are installed inside the sleeve 64 near the rope ring 61 and between the piston disc 63; the number of buffer components 66 is not less than four. Each buffer component 66 includes a first connecting piece 661 and a second connecting piece 662. A spring 663 is fixedly connected between the first connecting piece 661 and the second connecting piece 662. Plate 661, second connecting plate 662, and spring 663 are all sleeved on the cylindrical surface of guide rod 62. Four first connecting rods 664 are connected to the first connecting plate 661, and four second connecting rods 665 are connected to the second connecting plate 662. The other end of the first connecting rod 664 is hinged to the other end of the second connecting rod 665. The fixed connection buffer device is installed around the bottom and top of the aquaculture net cage. By setting multiple compressible and deformable buffer components 66 in the middle of sleeve 64 and piston disc 63, when the first connecting rope 4 or the second connecting rope 5 connected to the connecting buffer mechanism 6 is subjected to large wind and waves, a few ropes facing the wind direction are buffered by the deformation of the buffer components 66 to prevent the ropes from being pulled and broken.

[0036] Specifically, when using this aquaculture cage: the four corners at the bottom of the cage 1 are tightened with second connecting ropes 5 to shape the cage 1. A foldable connecting frame 3 is installed and fixed at the upper end of the cage 1. The connecting frame 3 is connected to the floating platform 2 by ropes 38. The ropes 38 are wound up and fixed to the floating platform 2 by a winch. The other end of the second connecting block 37 is connected to the first connecting rope 4. The first connecting rope 4 passes around the end of the floating platform 2 and is fixed to the bottom of the water. The middle of the first connecting rope 4 and the second connecting rope 5 is buffered by a connecting buffer mechanism 6. If the first connecting rope 4 connected to the upper end of the cage 1 breaks due to impact, When the aquaculture cage 1 loses its upward pull, it will sink to the seabed. At this time, the descent rope 38 of the aquaculture cage 1 will pull the second connecting block 37 inward, bringing the first folding rod 32 and the second folding rod 33 together. The upper opening of the aquaculture cage 1 will close and sink to the seabed, separating it from the sea surface waves, thus preventing damage to the aquaculture cage and preventing the farmed fish from escaping, reducing losses in the aquaculture industry. After the waves subside, the rope 38 will be pulled up again by the winch, and the aquaculture cage 1 will be repositioned and the first connecting rope 4 will be re-fixed to complete the repair of the aquaculture cage 1.

Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
