Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, specifically to a deep-sea aquaculture cage. Background Technology

[0002] In recent years, my country's coastal fisheries have experienced sustained and rapid development, making significant contributions to social progress. However, my country's fisheries facilities and equipment are outdated, and inland or near-shore aquaculture severely pollutes waterways. Therefore, adjusting and optimizing the fisheries industry structure, promoting the transformation and upgrading of fisheries, vigorously developing standardized and healthy aquaculture, reducing inland and near-shore aquaculture, and exploring offshore and developing deep-sea aquaculture are gradually becoming a development trend.

[0003] Currently, floating cages are widely used in deep-sea aquaculture. Floating cages make it easy to observe the aquaculture conditions inside, have a lower cost, and a relatively stable structure. However, they are susceptible to the effects of wind and waves. Most existing floating cages are circular or square, with a rigid beam frame that cannot be folded or retracted. This results in poor resistance to ocean currents and waves, and the steel pipes of the cages are directly subjected to the impact of wind and waves, making them prone to damage. Summary of the Invention

[0004] To address the shortcomings of existing aquaculture cages, such as poor resistance to ocean currents and waves and susceptibility to damage, this invention provides a deep-sea aquaculture cage.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A deep-sea aquaculture cage includes a first buoy, support rods, and a stop mechanism. The support rods are evenly distributed on the first buoy. A net is provided on the inner side of the support rod, and a gravity adjustment device is provided at the bottom of the net. The support rod includes an upper frame, a middle frame, and a lower frame. The upper frame is fixed to the first buoy. One end of the middle frame is hinged to the upper frame, and the other end of the middle frame is hinged to the lower frame. A connecting plate is fixedly connected to the middle of the middle frame. A through groove is provided in the middle of the lower frame, and a connecting rod is provided in the through groove. The stop mechanism is provided on the connecting rod. The connecting plate is connected to the connecting rod. Movable plates are respectively hinged to both ends of the connecting rod. The movable plates between two adjacent support rods are hinged.

[0007] Furthermore, a second float is connected to the bottom of the first float via a fixing frame, and the second float is connected to the third float via a walking platform, which facilitates the operation of the cage by technicians.

[0008] Furthermore, the stopping mechanism includes an upper stopping mechanism and a lower stopping mechanism. The upper stopping mechanism includes a support block, a first baffle, a second baffle, and an intermediate shaft. The support block is fixedly mounted on the connecting rod. The first baffle and the second baffle are sequentially arranged between the support block. The intermediate shaft passes through the support block, the first baffle, and the second baffle. Springs are provided between the first baffle and the second baffle and the support block. The upper stopping mechanism and the lower stopping mechanism have the same structure. The upper stopping mechanism and the lower stopping mechanism are symmetrically arranged with respect to the connecting rod, which facilitates the control of the contraction and extension of the middle frame and the lower frame.

[0009] Furthermore, the cross-sectional shape of the through groove is I-shaped, which facilitates the stop mechanism to limit the retraction of the support rod.

[0010] Furthermore, the gravity adjustment device is connected to the bottom of the support rod via a steel wire rope, which provides good control over the retraction of the support rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When encountering wind and waves, the middle and lower frames of the cage of the present invention can retract inward, so as to avoid the cage frame being damaged by excessive force. It is simple to operate, has low production cost, can be mass-produced, and is also suitable for use in groups with supporting equipment. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The embodiments of the present invention include: like Figure 1-4 As shown, a deep-sea aquaculture cage includes a first buoy 1, support rods 4, and a stop mechanism 5. The support rods 4 are evenly distributed on the first buoy 1. A net 6 is provided on the inner side of the support rod 4. A gravity adjustment device 7 is provided at the bottom of the net 6. The support rod 4 includes an upper frame 401, a middle frame 402, and a lower frame 403. The upper frame 401 is fixed on the first buoy 1. One end of the middle frame 402 is hinged to the upper frame 401, and the other end of the middle frame 402 is hinged to the lower frame 403. A connecting plate 9 is fixedly connected to the middle part of the middle frame 402. A through groove 8 is provided in the middle part of the lower frame 403. A connecting rod 10 is provided in the through groove 8. The stop mechanism 5 is provided on the connecting rod 10. The connecting plate 9 is connected to the connecting rod 10. Movable plates 11 are respectively hinged to both ends of the connecting rod 10. The movable plates 11 between two adjacent support rods 4 are hinged.

[0020] In this embodiment, a second float 2 is connected to the bottom of the first float 1 via a fixed frame, and the second float 2 is connected to the third float 3 via a walking platform, which facilitates the operation of the cage by technicians.

[0021] In this embodiment, the stopping mechanism 5 includes an upper stopping mechanism 501 and a lower stopping mechanism 502. The upper stopping mechanism 501 includes a support block 503, a first baffle 504, a second baffle 505, and an intermediate shaft 506. The support block 503 is fixedly mounted on the connecting rod 10. The first baffle 504 and the second baffle 505 are sequentially arranged between the support block 503. The intermediate shaft 506 passes through the support block 503, the first baffle 504, and the second baffle 505. A spring 507 is provided between the first baffle 504 and the second baffle 505 and the support block 503. The upper stopping mechanism 501 and the lower stopping mechanism 502 have the same structure. The upper stopping mechanism 501 and the lower stopping mechanism 502 are symmetrically arranged with respect to the connecting rod 10, which facilitates the control of the contraction and extension of the middle frame 402 and the lower frame 403.

[0022] In this embodiment, the cross-sectional shape of the through groove 8 is I-shaped, which facilitates the stop mechanism 5 to limit the contraction of the support rod 4.

[0023] In this embodiment, the gravity adjustment device 7 is connected to the bottom of the support rod 4 by a steel wire rope, which provides good control over the retraction of the support rod 4.

[0024] The workflow and working principle of this invention are as follows: First, the components are assembled and placed in the ocean. The gravity adjustment device 7 begins to increase weight, and the components below the second float 2 are submerged in water. When encountering large waves, the lower frame 403 of the net cage is pulled up, the gravity adjustment device 7 begins to reduce weight, the lower frame 403 begins to retract inward, and at the same time, the movable plate 11 moves downward, the connecting plate 9 moves inward, the stop mechanism 5 moves downward, and the lower stop mechanism 502 moves to the bottom of the channel 8 and is locked. When the waves stabilize, the lower frame 403 of the net cage is lowered, the gravity adjustment device 7 begins to increase weight, the connecting plate 9 moves outward, the stop mechanism 5 moves upward, and the upper stop mechanism 501 moves to the top of the channel 8 and is locked.
