Description

Technical Field

[0001] This utility model relates to the field of shrimp fishing tools, specifically to an assemblable net shrimp trap. Background Technology

[0002] Currently, there are two main design directions for shrimp traps on the market: box-shaped shrimp traps with a completely sturdy structure and net-shaped shrimp traps that can be deployed underwater. Box-shaped shrimp traps are mostly rigid structures and usually have an opening for catching shrimp. However, due to their rigid structure, box-shaped shrimp traps cannot be deployed in the water, limiting their catching range. They are also often less portable than net-shaped shrimp traps, as their multiple frames make them relatively heavy and difficult to lift from the water with ropes. Most netted shrimp traps are foldable flexible structures, consisting of a frame and netting. Because a significant portion is netting, they are foldable and lighter than box-shaped shrimp traps, making them easier to carry. The netting can be fully extended in water, increasing the catching area compared to box-shaped traps. However, netted shrimp traps lack a disassembly mechanism. Most existing traps have an opening at one end or a central opening, but when actually catching shrimp, their limbs often get caught in the netting. The flexible structure of the netting causes the netting to overlap, making catching the shrimp difficult. Utility Model Content

[0003] To address the above problems, this utility model provides an assemblable mesh shrimp trap.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An assemblable mesh shrimp trap comprises an enclosure net and a bottom net. The enclosure net includes a first rigid frame, which is a long V-shaped frame structure composed of an upper frame, two lower frames, and several transverse frames. A first mesh sheet is covered on the first rigid frame and fixed to the lower frames by a first waterproof tarpaulin. Several first metal round buckles are provided on the first waterproof tarpaulin. Several shrimp inlets are provided on both sides of the first rigid frame on the first mesh sheet. Protruding sections are provided at both ends of the upper frame. The bottom net includes a second rigid frame, which is a rectangular frame structure composed of two outer frames and several transverse inner frames. The rectangular frame structure matches the rectangle formed by the lower frames. A second mesh sheet is covered on the second rigid frame and fixed to the outer frames by a second waterproof tarpaulin. Several second metal round buckles are provided on the second waterproof tarpaulin, which match the positions of the first metal round buckles on the first waterproof tarpaulin and can be fastened to each other. Extension sections are left on both sides of the transverse sides of the rectangular frame structure on the second mesh sheet, and the ends of the extension sections are connected to binding ropes.

[0006] The materials selected for the first and second waterproof tarpaulins need to be non-absorbent and have a certain density so that the cage can sink. Optional materials include PVC and PE.

[0007] The binding rope needs to be of a certain length and toughness to facilitate binding and securing, as well as to retrieve the cage from the water;

[0008] This utility model design achieves the assembly and disassembly of the enclosure net and the bottom net through the interlocking and disassembly of metal round buckles and the raising and lowering of the binding rope, which facilitates relocation, cleaning and shrimp removal; the cage has a large fishing range and is convenient to use.

[0009] In some preferred embodiments, the transverse skeleton is evenly distributed on the upper skeleton and the lower skeleton; the evenly distributed transverse skeleton can improve the stability of the shrimp trap.

[0010] In some preferred embodiments, the cross-section of the long V-shaped skeleton structure is an isosceles triangle to further improve the stability of the shrimp trap.

[0011] In some preferred embodiments, the included angle of the long V-shaped skeleton structure is 60 degrees.

[0012] In some preferred embodiments, the first metal buckle is evenly distributed along the lower skeleton to improve the structural stability of the shrimp cage.

[0013] In some preferred embodiments, the shrimp inlet is a funnel shape formed by the inward concave connection of mesh panels, which is wider on the outside and narrower on the inside, ensuring that the shrimp can enter smoothly and reducing the chance of escape.

[0014] In some preferred embodiments, stainless steel hooks are welded to both ends of the upper frame to facilitate the binding of ropes.

[0015] In some preferred embodiments, the extension section matches the cross-section of the long V-shaped skeleton structure to prevent shrimp from escaping from the cage.

[0016] In some preferred embodiments, the ropes connected to the ends of the extended sections on both sides of the rectangular frame structure are of different lengths, with the longer rope facilitating the retrieval of the cage when the net is pulled ashore.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) In view of the problems of small fishing range and difficulty in carrying existing box-shaped shrimp traps and difficulty in taking shrimp from net-shaped shrimp traps, this utility model provides an assemblable net-shaped shrimp trap with simple structure and easy operation. Assembly and disassembly are achieved only by the metal round buckles set on the waterproof tarpaulin on the enclosure net and the bottom net, as well as the raising and lowering of iron hooks and ropes.

[0019] (2) The net shrimp cage described in this utility model is easy to harvest. After disassembly, the shrimp caught in the cage can be directly poured into a container. The shrimp in the shrimp cage can be easily harvested. Shrimp whose limbs are hooked on the net can also be carefully removed without damaging the shrimp, ensuring the integrity of the shrimp limbs to ensure the survival rate of subsequent transportation and breeding.

[0020] (3) The mesh shrimp cage described in this utility model is easy to carry, and the cage structure after disassembly is regular, making it easier to carry than the traditional box-type shrimp catching device.

[0021] (4) The disassembly and assembly structure of the net shrimp cage described in this utility model is simple. Even if the size of the cage is increased, it will not affect its assembly and disassembly function. On the contrary, it expands the fishing range and meets the usage requirements.

Detailed Implementation

[0028] The present invention will be further described in conjunction with the following embodiments.

[0029] An embodiment of this utility model relates to an assemblable mesh shrimp trap, see attached drawing. Figure 1-4The assemblable shrimp trap consists of a perimeter net 1 and a bottom net 2. The perimeter net 1 includes a first rigid frame, which is a long V-shaped frame structure composed of an upper frame 7, two lower frames 8, and several transverse frames 9. The cross-section of the long V-shaped frame structure is an isosceles triangle. The transverse frames 9 are evenly distributed on the upper frame 7 and the lower frames 8. A first net sheet 10 is covered on the first rigid frame. The first net sheet 10 is fixed to the lower frames 8 by a first waterproof tarpaulin 6. Several first metal round buckles 4 are provided on the first waterproof tarpaulin 6, which are evenly distributed along the lower frames 8. Several shrimp inlets 3 are provided on both sides of the first rigid frame of the first net sheet 10. The shrimp inlets 3 are funnel-shaped, formed by the inward indentation of the net sheet, and are wider on the outside and narrower on the inside. Stainless steel hooks 5 are welded to both ends of the upper frame 7. The bottom net 2... The system includes a second rigid frame, which is a rectangular frame structure composed of two outer frames 15 and several transverse inner frames 14. The rectangular frame structure matches the rectangle formed by the lower frame 8. The second rigid frame is covered with a second mesh 16, which is fixed to the outer frames 15 by a second waterproof tarpaulin 12. The second waterproof tarpaulin 12 is provided with several second metal round buckles 11 that match the positions of the first metal round buckles 4 on the first waterproof tarpaulin 6 and can be fastened to each other. The second mesh 16 has extension sections 17 on both transverse sides of the rectangular frame structure. The extension sections 17 are isosceles triangles that match the cross-section of the long V-shaped frame structure. The ends of the extension sections 17 are connected to net ropes 13. The net ropes 13 connected to the ends of the extension sections 17 on both transverse sides of the rectangular frame structure are of different lengths.

[0030] In this embodiment, the mesh shrimp cage is assembled by fastening the first metal round buckle 4 and the second metal round buckle 11, which are respectively set on the first waterproof tarpaulin 6 and the second waterproof tarpaulin 12. The mesh rope 13, which is connected to the ends of the isosceles triangular extensions 17 left on both sides of the rectangular frame structure, is tied to the stainless steel hooks 5 welded to both ends of the upper frame 7. This achieves the combination of the enclosure net 1 and the bottom net 2, forming a closed cage. Disassembly is achieved by opening the first metal round buckle 4 and the second metal round buckle 11 on the enclosure net 1 and the bottom net 2, and untying the hooks 5 attached to the upper frame 7. The stainless steel hooks 5 welded to both ends of the frame 7 can completely separate the enclosure net 1 and the bottom net 2. After disassembly, the shrimp in the shrimp trap can be easily harvested. Even if the shrimp's limbs are caught on the net, the shrimp can be easily removed. This avoids the problem of shrimp limbs being caught on the net when using traditional net traps, making it difficult to remove the shrimp. Due to its detachable overall structure, even if the overall length and width of the trap are increased, it will not affect the trap's portability. This allows the trap to catch shrimp even without bait, simply by virtue of its large catch range. Of course, bait can also be added to further increase the catch.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
