Description
Technical Field
[0001] This utility model relates to the field of fishing net array technology, specifically a large-scale net array structure for fishing. Background Technology
[0002] Fishing nets are indispensable tools in fisheries production. Coastal fishermen initially used simple nets to fish near the sea. During the Ming Dynasty, shallow-sea fishing nets such as scooping nets and rod nets appeared. After the Qing Dynasty, deep-sea fishing nets emerged, while inland river fishermen mostly used small fishing gear. A fishing net array refers to a large fishing facility composed of multiple fishing nets or tackle arranged in a certain way. It is usually used for large-scale fishing operations. Compared to a single net, a net array can cover a larger water area, increasing the fishing range and thus increasing the catch.
[0003] Traditional fishing net arrays are mostly one-piece structures, which are inconvenient to disassemble, making it difficult to increase or decrease the number of nets to adjust the length of the net array, thus limiting their practicality. To address these issues, a large-scale fishing net array structure is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a large-scale fishing net array structure, which solves the problem that most traditional fishing net array structures in the background art are one-piece, which are inconvenient to disassemble, and thus inconvenient to increase or decrease the number of nets to adjust the length of the net array.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a large net array structure for fishing, comprising a first net body, a second net body disposed on the left side of the first net body, and a third net body disposed on the left side of the second net body. A first mounting ring is fixedly connected to the outer left side of both the first and second net bodies. A limiting ring is fixedly connected to the left side of each of the two first mounting rings. Four limiting holes are provided on the outer side of each limiting ring. A second mounting ring is fixedly connected to the outer right side of both the second and third net bodies. A limiting groove is provided on the right side of each of the two second mounting rings. Four fixing cylinders are fixedly connected to the outer side of each of the two fixing cylinders. A telescopic groove is provided on the inner side of each fixing cylinder. A pull rod is slidably connected through and within the telescopic groove. A plug is fixedly connected to one end of each pull rod. An actuating element is provided on the outer side of each fixing cylinder. An escape door is provided at the left end of each of the first, second, and third net bodies. A fish inlet is provided on the right side of each of the escape doors at the left end of each of the first, second, and third net bodies.
[0006] By adopting the above technical solution, the pull rod slides by rotating the lever, which causes the insert post to retract and compress the spring, causing the insert post to exit the limiting hole, thus allowing the net body to be quickly disassembled.
[0007] As a further description of the above technical solution: a fish inlet is fixedly connected to the right side of the first net body.
[0008] By adopting the above technical solution, the funnel-shaped fish inlet expands the entrance area and guides the fish into the first net by using water flow or the swimming inertia of the fish.
[0009] As a further description of the above technical solution: the insertion post is disposed in the telescopic groove, and the insertion post penetrates the second mounting ring.
[0010] By adopting the above technical solution, it is convenient for the insert to be pulled out from the limiting hole and retracted into the expansion groove.
[0011] As a further description of the above technical solution: a rotating shaft is rotatably connected through the center of the lever, and the outer ring of the rotating shaft is rotatably connected to one end of the pull rod.
[0012] By adopting the above technical solution, the actuator and the pull rod are connected by a rotating shaft.
[0013] As a further description of the above technical solution: the outer ring of the pull rod is fitted with a spring, and the spring is disposed in the telescopic groove.
[0014] By adopting the above technical solution, the spring reset can drive the insertion post to extend out of the telescopic groove.
[0015] As a further description of the above technical solution: support rings are fixedly connected to the middle of the outer rings of the first mesh body, the second mesh body, and the third mesh body.
[0016] By adopting the above technical solutions, the structure of the net is maintained, the fishing space is expanded, and the net collapse is prevented.
[0017] As a further description of the above technical solution: the left end of the third net body is connected to a fish-catching net box.
[0018] By adopting the above technical solution, the fish-catching net cage is a closed structure that can be quickly disassembled. After the operation is completed, it is convenient to disconnect the connection between the third net body and the fish-catching net cage (such as untying the fixing rope or buckle) and directly lift the entire net cage off the water surface, reducing the risk of the catch escaping within the net array.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] This utility model provides a large-scale net array structure for fishing. The structure consists of a first mounting ring, a limiting ring, a limiting hole, a second mounting ring, a limiting groove, a fixing cylinder, a telescopic groove, a pull rod, an insert, a lever, and a rotating shaft working in coordination. The lever rotates, causing the pull rod to slide, which in turn causes the insert to contract and compress the spring, causing the insert to exit the limiting hole. Then, the limiting ring of the first mounting ring can be pulled out of the limiting groove of the second mounting ring for quick disassembly of the net. The length of the net array can be adjusted by increasing or decreasing the number of nets. Furthermore, the escape gate on the left side of the net adopts a one-way opening and closing structure, allowing fish to swim into the next net from the inlet but preventing them from escaping in the opposite direction, thus preventing fish backflow.

[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. 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.
[0026] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0027] Reference Figure 1-3This utility model discloses a large-scale net array structure for fishing, comprising a first net body 1, a second net body 2 disposed on the left side of the first net body 1, and a third net body 3 disposed on the left side of the second net body 2, with the first net body 1, second net body 2, and third net body 3 decreasing in size sequentially. First mounting rings 5 are fixedly connected to the outer left sides of both the first net body 1 and the second net body 2, facilitating the connection of the net bodies. Limiting rings 6 are fixedly connected to the left sides of both first mounting rings 5, serving a limiting function. Four limiting holes 7 are provided on the outer side of the limiting rings 6, which, in conjunction with inserts 13, also serve a limiting function. Second mounting rings 8 are fixedly connected to the outer right sides of both the second net body 2 and the third net body 3, with limiting grooves 9 provided on the right sides of both second mounting rings 8, which limit the limiting rings 6, improving the stability of the connection. Four fixing cylinders 10 are fixedly connected to the outer sides of the two second mounting rings 8. An expansion groove 11 is provided on the inner side of each fixing cylinder 10, through which a pull rod 12 is slidably connected. The pull rod 12 can drive the insertion post 13 to move. The insertion post 13 is fixedly connected to one end of the pull rod 12. A lever 14 is provided on the outer side of the fixing cylinder 10. An escape door 17 is provided at the left end of the first net body 1, the second net body 2, and the third net body 3. The escape door 17 adopts a one-way opening and closing structure, allowing fish to swim into the next net body through the fish inlet 20, but preventing them from escaping in the opposite direction, thus preventing the fish from flowing back. An escape door 17 is provided at the left end of the first net body 1, the second net body 2, and the third net body 3, and a fish inlet 20 is provided on the right side. The size of the fish inlets 20 decreases sequentially from the first net body 1 to the third net body 3.
[0028] Reference Figure 1-3 A fish inlet 4 is fixedly connected to the right side of the first net body 1. The funnel-shaped fish inlet 4 expands the entrance area and guides the fish into the first net body 1 using water flow or the inertia of fish swimming. The insertion post 13 is set in the telescopic groove 11 and passes through the second mounting ring 8, so that the insertion post 13 can be pulled out from the limiting hole 7 and retracted into the telescopic groove 11. A rotating shaft 15 is rotatably connected through the middle of the lever 14. The outer ring of the rotating shaft 15 is rotatably connected to the outward end of the pull rod 12. The lever 14 and the pull rod 12 are connected through the rotating shaft 15. A spring 16 is sleeved on the outer ring of the pull rod 12 and is set in the telescopic groove 11. The spring 16 can drive the insertion post 13 to extend out of the telescopic groove 11 by resetting. Support rings 18 are fixedly connected to the middle of the outer rings of the first net body 1, the second net body 2 and the third net body 3 to maintain the structure of the net body, expand the fishing space and prevent the net body from collapsing. The third net body 3 is connected to the fish-catching net box 19 at its left end. The connection between the end of the third net body 3 and the fish-catching net box 19 is detachable, which makes it easy to remove the fish from the fish-catching net box 19.
[0029] Working principle: Based on the distribution of the fish school, the first net body 1 to the third net body 3 are inserted into the limiting hole 7 through the insert post 13 and locked together with the first mounting ring 5 and the second mounting ring 8, forming a straight net array. This array is fixed to the fishing ground using anchors or buoys. Fish enter the net array through the fish inlet 4 and swim sequentially towards the third net body 3 along the fish inlet 20. The escape gate 17 prevents them from swimming in the opposite direction, and they eventually gather in the fish-collecting net box 19. Finally, the third net body 3 is disassembled from the fish-collecting net box 19, the fish-collecting net box 19 is lifted to harvest the catch, and the empty net box is replaced before continuing the operation. When it is necessary to disassemble the net body, the lever 14 is pulled outwards sequentially, rotating the lever 14 90° until its bottom is perpendicular to the outside of the fixing cylinder 10, thus limiting its position. The lever 14 rotates along the pivot 15, which in turn pulls the lever 12. The lever 12 drives the insert 13 to compress the spring 16 and retract it into the telescopic groove 11. At this time, the insert 13 disengages from the limiting hole 7, and the limiting ring 6 can be pulled out from the limiting groove 9 to achieve the disassembly of the two nets. During installation, the limiting ring 6 on the left side of one net is inserted into the limiting groove 9 on the right side of the other net, ensuring that the limiting hole 7 corresponds to the fixing cylinder 10. Then, the lever 14 is turned back, and the spring 16 returns to its original position, causing the insert 13 to extend out of the telescopic groove 11, pass through the second mounting ring 8, and be inserted into the limiting hole 7 outside the limiting ring 6, completing the installation between the two nets. If the length of the net array needs to be adjusted, the number of nets can be increased or decreased and reconnected.
