Description

Technical Field

[0001] This utility model relates to the field of deep-sea cage technology, and in particular to a fishing device for deep-sea cages. Background Technology

[0002] Existing technologies for catching fish in net cages cannot achieve multi-layered catching at once, and single-catch catching easily causes fish to be crushed and killed within the net. Multiple catches require repeated net changes, resulting in low catching efficiency. To address this problem, Chinese Patent Publication No. CN222216916U discloses a device for catching adult fish in aquaculture net cages. This device allows auxiliary equipment to move along the cage wall, enabling flipping and catching of fish, and also allows for the separate catching of fish fry.

[0003] In applying the above-mentioned existing technologies, it was found that they cannot be used in larger-sized aquaculture cages, especially in deep-sea cages. They also cannot be used for layered fishing, and the fish are still squeezed due to the large number of fish caught at once. In addition, fishing nets cannot be quickly set up and dismantled on aquaculture cages. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where it is difficult to achieve layered fishing in aquaculture cages, and at the same time, fishing nets cannot be quickly installed and removed from the cages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deep-sea net cage fishing device includes a net cage with a floating tube connecting truss. A connecting pipe is provided between the floating tubes of the net cage. A fishing device is mounted on the connecting pipe. The fishing device includes a fishing net. Several connecting components are provided between the fishing net and the net cage. Each connecting component includes a base, a movable baffle hinged to the base, a movable claw hinged to the base and engaging with the movable baffle, a limiting device engaged with the connecting pipe, a net hook connected to the fishing net, a cable frame, a locking block, and a locking groove.

[0007] Preferably, a first torsion spring is provided between the movable baffle and the base, and a second torsion spring is provided between the movable claw and the base.

[0008] Preferably, the connecting pipe is provided with a plurality of first ratchet teeth, and the movable pawl is provided with a plurality of second ratchet teeth, the first ratchet teeth meshing with the second ratchet teeth, and the first ratchet teeth engaging with the limiting device.

[0009] Preferably, the limiting device includes a limiting frame, the limiting frame is U-shaped, the limiting frame is hinged to the base, a third torsion spring is provided between the limiting frame and the base, the limiting frame is engaged with the first ratchet, and a U-shaped locking member is provided on the limiting frame, the U-shaped locking member abutting against the base.

[0010] Preferably, the card block corresponds to the outer dimensions of the card slot, and the cross-section of the card block is quadrilateral.

[0011] Preferably, the fishing net is provided with several buoyancy chambers.

[0012] The beneficial effects proposed by this utility model are as follows:

[0013] The connecting pipe is fitted onto the float pipe inside the net cage. During fishing operations, the operator connects the connecting assembly to the connecting pipe. In this process, the operator holds the base, moves the movable baffle toward the connecting pipe, and moves the base until the movable baffle abuts against the connecting pipe. Then, the base is continuously moved toward the axial direction of the connecting pipe. At this point, the connecting pipe pushes up the movable baffle. When the movable baffle is pushed up and flipped, the engagement between the movable baffle and the movable claw is released. Simultaneously, the movable baffle pushes up the movable claw, causing it to flip. The connecting pipe then passes through the movable baffle and abuts against the base. The limiting device fixes the connecting pipe in place. This completes the installation of the connecting assembly on the net cage. At this time, the fishing net is fixed to the base by the net hook. The operator installs several connecting assemblies on the net cage and spreads out the fishing net. When the fishing net is hauled in, a lifting device pulls the cable, which is connected to the cable frame. During this pulling process, the cable frame moves the base, at which point the connecting pipe engages with the movable claw, and the base continues to move, pushing open the movable claw until the connecting pipe separates from the base, thus separating the connecting component from the net cage. This connecting component enables rapid installation and connection of the fishing net and the net cage, improving efficiency during fishing operations. Furthermore, the locking block 9 of one base 4 engages with the locking groove 10 of another base 4. This engagement allows the bases 4 to be stacked, enabling batch and layered fishing using a "net within a net" method. Layered fishing reduces the risk of fish crushing caused by large-scale fishing at once. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1 to 10A deep-sea net cage fishing device includes a net cage 1 with a floating tube connecting truss. A connecting pipe 2 is provided between the floating tubes on the net cage 1. A fishing device is mounted on the connecting pipe 2. The fishing device includes a fishing net 3. Several connecting components are provided between the fishing net 3 and the net cage 1. Each connecting component includes a base 4. A movable baffle 5 is provided on the base 4 and is hinged to the base 4. A movable claw 6 is provided on the base 4 and is hinged to the base 4. The movable claw 6 engages with the movable baffle 5. A limiting device is provided on the base 4 and is engaged with the connecting pipe 2. A net hook 7 is provided on the base 4 and is connected to the fishing net 3. A cable frame 8 is provided on the base 4. A locking block 9 is provided on the base 4. A locking groove 10 is provided on the base 4. Specifically, the connecting pipe 2 is fitted onto the floating pipe in the net cage 1. During fishing operations, the operator connects the connecting assembly to the connecting pipe 2. In this process, the operator holds the base 4, moves the movable baffle 5 toward the connecting pipe 2, and moves the base 4 until the movable baffle 5 abuts against the connecting pipe 2. Then, the operator continues to move the base 4 toward the axial diameter of the connecting pipe 2. At this time, the connecting pipe 2 lifts the movable baffle 5. When the movable baffle 5 is lifted and flipped, the engagement between the movable baffle 5 and the movable claw 6 is released. At the same time, the movable baffle 5 lifts the movable claw 6, and the movable claw 6 flips. Subsequently, the connecting pipe 2 passes through the movable baffle 5 and abuts against the base 4. The limiting device fixes the connecting pipe 2. The above achieves the installation of the connecting assembly on the net cage 1. At this time, the fishing net 3 is fixed to the base 4 by the hook 7. The operator installs several connecting components on the net box 1 and spreads out the fishing net 3. When the fishing net 3 is to be retrieved, the lifting equipment pulls the cable, which is connected to the cable frame 8. During the pulling of the cable, the cable frame 8 moves the base 4. At this time, the connecting pipe 2 abuts against the movable claw 6, and the base 4 continues to move, pushing open the movable claw 6 until the connecting pipe 2 separates from the base 4, thus separating the connecting components from the net box 1. The above-mentioned connecting components enable the rapid installation and connection of the fishing net 3 and the net box 1, improving the efficiency of fishing operations using the fishing net 3. Furthermore, the locking block 9 of the base 4 is engaged with the locking slot 10 of another base 4. The base 4 can be stacked and connected through the engagement between the locking block 9 and the locking slot 10, thereby enabling batch and layered fishing in the "net within a net" manner during the fishing process. By using layered fishing, the risk of fish being crushed due to a large number of fish caught at once can be reduced.

[0027] Specifically, a first torsion spring 11 is provided between the movable baffle 5 and the base 4, and a second torsion spring 12 is provided between the movable claw 6 and the base 4. When a pushing force is applied to the movable baffle 5 and causes it to flip, the force, along with the base 4, acts on both ends of the first torsion spring 11. At this time, the movable baffle 5 and the base 4 compress the first torsion spring 11, causing the first torsion spring 11 to generate and store elastic force. When the applied pushing force is released, the first torsion spring 11 releases its elastic force and pushes the movable baffle 5 to rotate in the opposite direction until the movable baffle 5 returns to its original position, thus achieving automatic reset of the movable baffle 5. Similarly, the second torsion spring 12 is used for the reset of the movable claw 6. The working principle of the reset of the movable claw 6 under the action of the second torsion spring 12 is the same as that of the movable baffle 5, and will not be described again.

[0028] Specifically, the connecting pipe 2 is provided with several groups of first ratchet teeth 13, and the movable claw 6 is provided with several groups of second ratchet teeth 14. The first ratchet teeth 13 and the second ratchet teeth 14 engage, and another group of first ratchet teeth 13 engages with the limiting device. The connecting pipe 2 can be used to connect the floating pipe on the cage 1. When the connecting pipe 2 is engaged with the base 4, one end face of the movable claw 6 abuts against the connecting pipe 2. At this time, the second ratchet teeth 14 provided on the movable claw 6 engage with the first ratchet teeth 13, thereby fixing the connecting pipe 2 in the base 4 and reducing the possibility of the connecting pipe 2 rotating. Furthermore, the limiting device engages with another group of first ratchet teeth 13, making the support of the connecting pipe 2 in the base 4 balanced, further improving the stability of the connecting pipe 2 in the base 4 and reducing the loosening problem of the connecting pipe 2 due to its own problems.

[0029] Specifically, the limiting device includes a limiting frame 15, which is U-shaped and hinged to the base 4. A third torsion spring 18 is provided between the limiting frame 15 and the base 4. The limiting frame 15 engages with the first ratchet 13, and a U-shaped locking member 16 is provided on the limiting frame 15, which abuts against the base 4. During the movement of the connecting pipe 2 within the base 4, the first ratchet 13 initially abuts against the limiting frame 15. As the connecting pipe 2 continues to move, the first ratchet 13 pushes the limiting frame 15 to rotate. At this time, a gradually decreasing angle is formed between the limiting frame 15 and the base 4, compressing the third torsion spring 18. When the first ratchet 13 passes the limiting frame 15, the limiting frame 15 falls into the tooth groove between the first ratchet 13. The third torsion spring 18 releases its stored elastic force, causing the limiting frame 15 to lock in the tooth groove. At this time, when the moving thrust on the connecting pipe 2 is released, the limiting frame 15 and the second ratchet 14 provide a supporting force for the connecting pipe 2, thereby fixing the connecting pipe 2 in the base 4. Based on this, in order to lock the limiting frame 15 when it engages with the first ratchet 13, the U-shaped locking piece 16 engages with the base 4. This process creates a pulling force on the limiting frame 15 relative to the U-shaped locking piece 16 and the base 4, thereby limiting the movement of the limiting frame 15 during operation.

[0030] Specifically, the locking block 9 corresponds to the outer dimensions of the locking groove 10, and the cross-section of the locking block 9 is quadrilateral. The quadrilateral cross-sections of the locking block 9 and the locking groove 10, when engaged, prevent relative rotation between them during the engagement process, thus contributing to the stability of the fishing net 3 laying and reducing the risk of knots between nets.

[0031] Specifically, the fishing net 3 is equipped with several buoyancy chambers 17. Each buoyancy chamber 17 is connected to the fishing net 3 via cables. Each buoyancy chamber 17 has an inlet valve (not shown) and an outlet valve (not shown), each connected to a pipe (not shown) and an external water pump. When the buoyancy chamber 17 submerges, the external water pump starts, and water is injected through the pipes into the inlet valve and then into the buoyancy chamber 17, increasing its weight. The buoyancy chamber 17 then causes the fishing net 3 to sink. By controlling the amount of water injected, the sinking depth of the fishing net 3 can be controlled, enabling stratified fishing. When the lifting equipment lifts the fishing net 3, the outlet valve opens, and the external water pump pumps out the water from the buoyancy chamber 17 through the pipes, reducing the burden on the lifting equipment and improving lifting efficiency. The structure and working principle of the buoyancy chamber 17 described above, including the inlet valve and the outlet valve, are all technical means commonly used by those skilled in the art in the prior art. They will not be described in detail here, and the relevant technical features are not marked in the accompanying drawings.

[0032] 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.
