Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, specifically to a fixing anchor for deep-water aquaculture cages. Background Technology

[0002] Aquaculture cages are an important type of aquaculture facility that enables high-density intensive aquaculture by setting up cages consisting of frames, nets, and fixing systems in water bodies.

[0003] The aquaculture cage structure includes a net body, a frame structure made of bamboo or plastic pipes at the top of the net body, floats fixed to the side of the frame structure to make the frame structure float on the water surface, and anchors set at the bottom of the net body or frame structure to position the cage.

[0004] However, existing net cage anchors generally have four counterweight anchors evenly placed on the lower edge of the net body to ensure the structure of the net body and improve its resistance to wind and waves. However, when the net cage is placed, the sinking of multiple counterweight anchors can easily pull on the net body, causing damage to the net body. In addition, the position of each anchor body needs to be properly positioned to prevent the net body from getting tangled. The overall installation process of aquaculture net cages is quite complicated. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing net cage anchors often have four counterweight anchors evenly placed on the lower edge of the net body to protect the structure and improve its resistance to wind and waves. However, during installation, the net body is prone to sinking and being damaged, and the anchors also need to be positioned to prevent entanglement, making the overall installation process of the aquaculture net cage quite complicated.

[0006] To solve the above problems, the technical solution adopted by this utility model is a deep-water aquaculture cage fixing anchor, including a cage structure, a cage body, a frame fixed at the top of the cage body, floats fixed at the corners of the frame, an anchor body structure at the bottom of the cage body, the anchor body structure including four connecting anchor ropes fixed to the lower side of the cage body, a base rope fixed to the middle of the lower side of the cage body, the bottom ends of the four connecting anchor ropes fixed to the side of the base rope, a limiting rope connecting the connecting anchor ropes and the base rope, a supporting sleeve sleeved on the outside of the limiting rope, a positioning float fixed to one end of the base rope, a traction rope fixed to one side of the cage body, one end of the traction rope sleeved on the outside of the base rope, and a counterweight anchor body sleeved on the outside of the base rope.

[0007] As a further embodiment of this utility model: a stop block 1 is fixed on the side of the base rope above the counterweight anchor body, and its position is located at the water depth, which can block the position of the counterweight anchor body; a stop block 2 is fixed on the side of the base rope below the traction rope sleeve, which can position the traction position of the traction rope.

[0008] As a further embodiment of this utility model: the positioning float is connected and fixed to the base ropes of the four net cage structures to position the net cage structures. The float is red or a color that differs from the color of the sea surface, which facilitates the determination of the position of the base rope end.

[0009] As a further embodiment of this invention, the length of the base rope is greater than twice the depth of the water body, ensuring that the counterweight anchor can sink to the bottom and that a certain distance is maintained between multiple cage structures.

[0010] As a further embodiment of this utility model: a ring lug is fixed at the top of the counterweight anchor body, and the base rope is threaded through the ring lug.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This application adds an anchor structure, which can pull the counterweight anchor body slowly down through the base rope without dragging the net body. In addition, it is equipped with a support sleeve structure, which can ensure the structural positioning of the net body when it is lowered and prevent the net body from getting tangled.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0020] Combined with appendix Figure 1-3 It can be seen that the structure includes a net cage, which includes a net body 1. A frame 2 is fixed at the top of the net body 1, and floats 3 are fixed at the corners of the frame 2. An anchor structure is provided below the net body 1. The anchor structure includes four connecting anchor ropes 4 fixed to the lower side of the net body 1. A base rope 5 is fixed in the middle of the lower side of the net body 1. The length of the base rope 5 is greater than twice the water depth to ensure that the counterweight anchor 10 can sink to the bottom and to maintain a certain distance between multiple net cage structures. The bottom ends of the four connecting anchor ropes 4 are fixed to the sides of the base rope 5. A limiting rope 6 is provided between the connecting anchor ropes 4 and the base rope 5. A support sleeve 7 is sleeved on the outside of the limiting rope 6.

[0021] A positioning float 8 is fixed at one end of the base rope 5. The positioning float 8 is connected and fixed to the base rope 5 of the four net cage structures to position the net cage structures. Its color is red or a color that differs from the color of the sea surface, which makes it easy to determine the position of the end of the base rope 5. A traction rope 9 is fixed on one side of the net body 1. One end of the traction rope 9 is sleeved on the outside of the base rope 5. A counterweight anchor 10 is sleeved on the outside of the base rope 5. A ring lug is fixed at the top of the counterweight anchor 10. The base rope 5 is passed through the ring lug. A stop block 11 is fixed on the side of the base rope 5 above the counterweight anchor 10. Its position is located at the water depth and can block the position of the counterweight anchor 10. A stop block 2 12 is fixed on the side of the base rope 5 below the sleeve of the traction rope 9, which can locate the traction position of the traction rope 9.

[0022] The working principle of this application is as follows: When placing the net cage structure, firstly, the net body 1, frame 2, and float 3 are placed above the water surface. At the same time, the connecting anchor rope 4, base rope 5, and support sleeve 7 are lowered into the water. The support sleeve 7 can ensure that the structure of the net body 1 will not deform. Then, one end of the base rope 5 is passed through the lug of the counterweight anchor body 10, and a stop block 11 is fixed on the side of the base rope 5 at the water depth. A stop block 2 12 is fixed near one end of the base rope 5. Then, one end of the base rope 5 is passed through the buckle of one end of the traction rope 9 and limited by the stop block 2 12. Then, the base rope 5 is slowly lowered into the water below the counterweight anchor body 10 using a traction device so that the counterweight anchor body 10 can sink to the bottom without pulling on the net body 1. Then, one end of the base rope 5 is connected and fixed to the positioning float 8, and the placement is completed.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
