Description

Technical Field

[0001] The utility model belongs to the technical field of marine ecological aquaculture, and particularly relates to a suspension power system and a marine ecological aquaculture cage. Background Art

[0002] Cages are important facilities for marine ecological aquaculture. Different from conventional water aquaculture, marine ecological aquaculture is usually in deeper waters and is subject to greater wind and wave impacts. Therefore, steel structure cages are required. At the same time, the cage needs to be sunk underwater, buoyancy is provided by floats, and guy wires are needed to be connected to the seabed for cage traction and fixation. The disadvantage of this cage structure is that it is difficult to adjust the position and height of the cage. When the water area needs to be changed, the guy wires need to be pulled out and the whole cage needs to float to the water surface for transfer, which is time-consuming and laborious, occupies a lot of labor and has poor flexibility. Therefore, it cannot meet the application needs of small-scale marine ranches and fishermen groups. Summary of the Utility Model

[0006] In some embodiments, each group of suspension air bags includes a plurality of flat air cushions arranged in a stacked manner up and down inside the frame body, and the flat air cushions are sequentially communicated; wherein, the buoyancy adjustment mechanism is used to inflate each flat air cushion from top to bottom in sequence and exhaust each flat air cushion from bottom to top in sequence.

[0007] Exemplarily, the flat air cushion of the top layer of each group of suspension airbags is fixedly connected to the frame, and the remaining layers of flat air cushions are respectively fixed to the flat air cushions of their respective upper layers.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the orientation or positional relationship indicated by terms such as "above", "below", "front", "rear", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0023] Please refer to Figures 1 to 5 , and now the suspension power system provided by the present utility model will be described. The suspension power system includes a connecting frame 10, a plurality of balance air bags 20, multiple groups of suspension air bags 30, and a buoyancy adjustment mechanism 40; wherein, the connecting frame 10 is used to be connected to the periphery of the cage body 50; the plurality of balance air bags 20 are sequentially distributed around the cage body 50, and each balance air bag 20 is connected to the top of the connecting frame 10; the multiple groups of suspension air bags 30 are sequentially distributed around the cage body 50 and are located below the balance air bags 20. Each group of suspension air bags 30 is disposed inside the connecting frame 10. Each group of suspension air bags 30 is used to inflate and expand synchronously to drive the cage body 50 to float, and is also used to exhaust and contract synchronously to make the cage body 50 sink, and is also used to maintain the current inflation amount to make the cage body 50 hover; the buoyancy adjustment mechanism 40 is connected to the four corner positions of the connecting frame 10, and the buoyancy adjustment mechanism 40 is respectively connected to each group of suspension air bags 30, and is used to synchronously adjust the inflation amount of each group of suspension air bags 30.

[0024] It should be noted that the cage body 50 is composed of a plurality of cells distributed in an array. Each cell forms an independent aquaculture space through a connecting net; the connecting frame 10 can be integral or assembled in a split manner. Considering the operation flexibility and convenience, the connecting frame 10 preferably adopts a split splicing structure here, that is, the connecting frame 10 is formed by sequentially assembling a plurality of parts matching the cell size to form a form that surrounds the cage body 50 as a whole around the periphery.

[0025] On the basis described above, the balance air bags 20 can be successively connected to the top of the connecting frame 10 corresponding to the side length dimensions of each cell, and the balance air bags 20 are used to form buoyancy obliquely above the four sides of the cage body 50, so as to improve the balance ability of the cage body 50 to resist wind waves and undercurrents; the inside of the connecting frame 10 can be understood as the space between the edges of its cuboid frame, and the floating air bags 30 are arranged inside the connecting frame 10. The floating air bags 30 are inflated or deflated through the buoyancy adjustment mechanism 40 to make the floating air bags 30 expand or contract, so as to realize the adjustment of buoyancy, and further meet the requirements of the cage body 50 for floating, sinking and hovering.

[0026] In this embodiment, the four waterproof boxes 41 are respectively connected to the four corner positions, which can ensure the overall structural balance. At the same time, the water pumps and exhaust valves 412 in each waterproof box 41 can be respectively used for one group of floating air bags 30, so as to improve the inflation and exhaust efficiency.

[0027] Compared with the prior art, for the floating power system provided in this embodiment, the connecting frame 10 is fixedly surrounded by the cage body 50 as the installation basis for the balance air bags 20 and the floating air bags 30. The balance air bags 20 arranged around the top of the connecting frame 10 and surrounding the cage body 50 can reduce the overall center of gravity, and further reduce the swaying amplitude of the cage body 50 under wind waves and undercurrents, improve the stability of the cage body 50. The buoyancy adjustment mechanism 40 inflates or exhausts each group of floating air bags 30 as needed, so that the volume of the floating air bags 30 changes due to the change of the inflation amount inside the floating air bags 30, so as to adjust the buoyancy generated by the floating air bags 30. When the overall buoyancy of the balance air bags 20 and the floating air bags 30 is greater than the gravity of the overall cage structure, floating can be realized, and vice versa for sinking. Thus, the cage body 50 can flexibly adjust the depth under the water surface, and when the cage body 50 reaches the target depth, the overall buoyancy is balanced with the overall gravity by adjusting the inflation amount of the floating air bags 30, so that the cage body 50 can hover at the current depth, can maintain the floating state and transfer the underwater position at the target depth, without making the cage body 50 surface, with high operation flexibility and labor saving, which is conducive to popularization and application in small-scale marine ranches and fishermen groups.

[0028] In some embodiments, referring to Figure 2 , the connecting frame 10 includes four rows of frame bodies 100, the four rows of frame bodies 100 are respectively connected to the four sides of the cage body 50, and each row of frame bodies 100 includes a plurality of frame bodies 100 corresponding to each cage cell of the cage body 50 one by one; wherein, one balance air bag 20 is connected above each frame body 100, and one group of floating air bags 30 is connected inside each frame body 100.

[0029] Here, the cage body 50 is a cube or cuboid frame composed of multiple cells distributed in an array. Therefore, the cage body 50 has four sides, and a row of frames 100 is connected to each side. Moreover, the length of each frame 100 corresponds to the side length of each cell. Adjacent frames 100 can be fixed by screwing. Thus, a balance airbag 20 and a group of floating airbags 30 can be installed on each frame 100. As a result, each frame 100 can form an independent modular unit, which is convenient for disassembling and transporting each modular unit when the cage needs to be disassembled as a whole later, thereby avoiding the large overall structure from affecting the transfer flexibility.

[0030] In some possible implementation manners, please refer to Figures 2 to 4 , each group of floating airbags 30 includes a plurality of flat air cushions 300 arranged in layers up and down inside the frame 100, and the flat air cushions 300 communicate with each other in sequence; among them, the buoyancy adjustment mechanism 40 is used to inflate each flat air cushion 300 in sequence from top to bottom and exhaust each flat air cushion 300 in sequence from bottom to top. By using a plurality of flat air cushions 300 stacked to form the floating airbag 30, and enabling each flat air cushion 300 to expand or contract in the manner of inflating from top to bottom and exhausting from bottom to top, it can always ensure that the center of gravity of the overall structure is at the lowest position, thereby improving the floating stability of the cage body 50.

[0031] Furthermore, the flat air cushion 300 at the top layer of each group of floating airbags 30 is fixedly connected to the frame 100, and the remaining flat air cushions 300 of each layer are respectively fixedly attached to the bottom surface of the flat air cushion 300 of their upper layer. Since the remaining flat air cushions 300 except the top layer will shrink and tightly adhere to the bottom surface of the flat air cushion 300 of the upper layer under the seawater pressure after being emptied, there will be a change in the relative position with the frame 100. Therefore, only the flat air cushion 300 at the top layer is fixedly connected to the frame 100, and the remaining flat air cushions 300 can be fixedly attached to each other in sequence by bonding or other means, which can ensure the smooth expansion and contraction of each group of floating airbags 30.

[0032] Specifically, in this embodiment, as Figures 3 to 5 shown, adjacent flat air cushions 300 are connected through one-way air valves 301, and each flat air cushion 300 is provided with an exhaust pipe 302; the buoyancy adjustment mechanism 40 includes four waterproof boxes 41 respectively connected to the corner positions of the connecting frame 10, and a float intake pipe 42; among them, the float intake pipe 42 is used to float on the water surface and communicate with each waterproof box 41; an air pump 411 and an exhaust valve 412 are provided in each waterproof box 41, the air pump 411 is connected to the flat air cushion 300 at the top layer of the floating airbag 30, and each exhaust pipe 302 is connected to the exhaust valve 412.

[0033] The one-way air valve 301 has a threshold for opening under a set pressure difference. In this embodiment, when the upper flat air cushion 300 is filled with air, the air pressure rises and drives the corresponding one-way air valve 301 to open, thereby starting to inflate the next lower flat air cushion 300. When the next lower flat air cushion 300 is filled, the air pressure rises and drives the corresponding one-way air valve 301 to open, thereby starting to inflate the flat air cushion 300 in the next lower layer. By repeating this process, each flat air cushion 300 can be filled from top to bottom in sequence. During the inflation process, air enters the waterproof box 41 through the float intake pipe 42, thereby meeting the continuous air intake requirement of the air pump 411. When exhausting, the valve holes connecting the exhaust valve 412 to each exhaust pipe 302 can be opened in sequence, so that each flat air cushion 300 can be emptied from bottom to top in sequence. It should be noted that in this embodiment, the emptying process of the flat air cushion 300 depends on the seawater pressure. When the flat air cushion 300 is connected to the waterproof box 41 through the exhaust pipe 302, the squeezing force of the seawater on it causes the air inside to be discharged into the waterproof box 41, and then discharged through the float intake pipe 42.

[0034] Here, the float intake pipe 42 can be specifically understood as using a float 421 floating on the sea surface to connect the air pipe, so that one end of the air pipe can always be above the water surface, and at the same time, the other end of the air pipe is connected to the waterproof box 41. This can ensure that the inside of the waterproof box 41 can always communicate with the outside space, thereby meeting the air intake requirement of the air pump 411 and the exhaust requirement of the exhaust valve 412. At the same time, the waterproof box 41 can avoid the water pump and the drain valve from touching the water as a closed cavity underwater, thereby ensuring the stability of inflation and exhaust.

[0035] It should be noted that in this embodiment, as Figure 5 shown, a controller 413 is provided in the waterproof box 41. The exhaust valve 412 and the air pump 411 are both electrically connected to the controller 413. When exhausting, the controller 413 controls the valve ports of the exhaust valve 412 to open and close in sequence. When inflating, the controller 413 controls all the valve ports of the exhaust valve 412 to remain closed, and at the same time controls the air pump 411 to start running. For the convenience of operation, a remote operation module commonly used in the prior art can be set in the controller 413 to facilitate the operator to operate the controller 413 on the offshore operation platform.

[0036] Optionally, in this embodiment, a power supply wire harness 422 is tied to the float intake pipe 42. The power supply wire harness 422 is used to connect to the power supply of the offshore operation platform. The power supply wire harness 422 is sealed and penetrates into the waterproof box 41 and is electrically connected to the air pump 411. Here, the air pump 411 is an electric pump with a small volume and high working efficiency, and draws power from the power supply port of the offshore operation platform through the power supply wire harness 422 extending out of the sea surface along with the float intake pipe 42 for operation, which is convenient and stable.

[0037] Exemplarily, as Figure 1As shown, a plurality of straps 200 are spaced apart and distributed on each balance airbag 20. Each strap 200 surrounds the balance airbag 20 and is detachably connected to the top of the connecting frame 10. The strap 200 can be adhesively fixed to the surface of the balance airbag 20, thereby improving the binding stability of the strap 200 to the balance airbag 20. At the same time, the strap 200 is fixedly connected to the connecting frame 10. The specific connection method can be that after a fastener passes through the strap 200, it is screwed onto the connecting frame 10, so that the balance airbag 20 can be conveniently disassembled and assembled.

[0038] Based on the same inventive concept, in combination with Figures 1 to 5 it is understood that the embodiment of the present application further provides a marine ecological aquaculture cage, including the above-mentioned suspension power system.

[0039] Compared with the prior art, the marine ecological aquaculture cage provided in this embodiment adopts the above-mentioned suspension power system. The main body 50 of the cage can flexibly adjust its depth under the water surface. When the main body 50 of the cage reaches the target depth, the overall buoyancy is balanced with the overall gravity by adjusting the inflation amount of the suspension airbag 30, so that the main body 50 of the cage can hover at the current depth, and can maintain a suspended state to transfer the underwater position at the target depth without making the main body 50 of the cage emerge from the water surface. It has high operation flexibility and saves labor, which is conducive to popularization and application in small-scale marine ranches and fishermen groups.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
