Description

Technical Field

[0001] This utility model relates to the field of fishing tools, specifically a double-sided fish trap. Background Technology

[0002] A fish trap, also known as a fish cage net, is used to catch fish, shrimp, crabs and other aquatic products in rivers, lakes, ponds, reservoirs, streams and shallow seas.

[0003] Currently used fish traps typically have only one fish inlet per section, with inlets spaced apart on both sides. This limits the number of inlets and results in low fishing efficiency. For example, Chinese invention patent application CN114027271A discloses a selectively catching fish trap net, the specification of which includes... Figure 1 The structure of this part represents the commonly used bottom trap structure. It can be seen that there is only one inlet on each section. Therefore, the effective fish-entry area can only reach a maximum of 25% of the surface area of ​​the main body of the trap (excluding the tip of the net), resulting in limited fishing efficiency.

[0004] For the reasons mentioned above, it is necessary to propose a bottom trap that increases the proportion of fish-intake area and improves fishing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a double-sided fish trap, which solves the problems of small fish-entry area ratio and low fishing efficiency in existing fish traps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A double-sided fish trap includes a frame and a net. The net forms conical net pockets at the front and rear ends of the frame and is connected to the frame. The net forms net walls on the upper and lower surfaces of the frame and is connected to the frame. Multiple fish inlets are provided on both the left and right sides of the frame. The fish inlets on the same side of the frame are connected sequentially and arranged along the length of the frame. The fish inlets gradually narrow towards the inside of the frame to form inner openings. The inner openings of the fish inlets on both sides of the frame are arranged alternately.

[0008] Preferably, the skeleton includes several square keels, the upper and lower parts of the square keels are connected by a mesh wall, the square keels at both ends of the skeleton are connected to the net, and the fish inlet is connected between two adjacent square keels.

[0009] Preferably, the outer opening of the fish inlet is rectangular, with its top and bottom sides connected to the net wall and its left and right sides connected to the sides of the square keel.

[0010] Preferably, the line connecting the center point of the outer opening and the center point of the inner opening forms an angle of 50°-70° with the central axis of the skeleton.

[0011] Preferably, the net bag has a fish inlet, one end of which is connected to one end of the skeleton, and the other end gradually narrows and extends into the net bag.

[0012] Beneficial effects:

[0013] 1. This utility model has fish inlets continuously set on both sides of the fish trap. With the main body length of the fish trap remaining unchanged, the number of fish inlets and the area for fish entry are at least doubled, which greatly improves the fishing efficiency.

[0014] 2. The fish inlets on both sides of this utility model are arranged in an alternating manner, and the line connecting the center point of the outer inlet and the center point of the inner inlet forms an angle of 50°-70° with the central axis of the skeleton, which effectively prevents fish from escaping and further improves the fishing efficiency.

[0025] like Figure 1 , Figure 5 As shown, this utility model provides a double-sided fish trap, including a frame 1 and a net. The net forms conical net pockets 2 at the front and rear ends of the frame 1 and is connected to the frame 1. The net forms net walls 5 on the upper and lower surfaces of the frame 1 and is connected to the frame 1. Multiple fish inlets 4 are provided on both the left and right sides of the frame 1. The fish inlets 4 on the same side of the frame 1 are connected sequentially and arranged along the length of the frame 1. The fish inlets 4 gradually narrow towards the inside of the frame 1 to form inner openings 401. The inner openings 401 of the fish inlets 4 on both sides of the frame 1 are arranged alternately.

[0026] like Figure 2 , Figure 3 , Figure 5 As shown, the fish inlets 4 located on the same side of the frame 1 are connected sequentially and arranged along the length of the frame 1. That is to say, each section of the frame 1 has two fish inlets, and the fish inlet area is 50% of the main body of the fish trap excluding the net. Figure 1 , Figure 4 As shown, the inner openings 401 of the fish inlet 4 are arranged in an alternating pattern, which effectively prevents fish from escaping.

[0027] Furthermore, such as Figure 6 As shown, the skeleton 1 includes several square keels 101, the upper and lower parts of the several square keels 101 are connected by a mesh wall 5, the square keels 101 located at both ends of the skeleton 1 are connected to the net bag 2, and the fish inlet 4 is connected between two adjacent square keels 101.

[0028] The number of keels 101 is set according to the length and number of sections of the cage. The distance between each two adjacent square keels 101 is one section. At the same time, a ring keel support can be set in the net bag 2 as needed. The preferred material for the frame is steel.

[0029] Furthermore, such as Figure 2 , Figure 3 As shown, the outer opening 402 of the fish inlet 4 is rectangular, with its upper and lower sides connected to the net wall 5 and its left and right sides connected to the sides of the square keel 101. The outer opening 402 of the fish inlet 4 occupies the entire side surface of the fish cage frame 1.

[0030] Furthermore, such as Figure 7 As shown, the line connecting the center point of the outer opening 402 and the center point of the inner opening 401 forms an angle of 50°-70° with the central axis of the skeleton 1;

[0031] To facilitate folding, if a soft nylon barbed inlet is used as the fish inlet, the inner opening 401 of the fish inlet 4 can be tied to the square keel 101 with a nylon rope so that the position of the inner opening 401 is fixed when the fish trap is unfolded.

[0032] Furthermore, such as Figure 1 As shown, the net bag 2 is provided with a fish inlet 3. One end of the fish inlet 3 is connected to one end of the frame 1, and the other end gradually narrows and extends into the net bag 2.

[0033] The fish are further prevented from escaping by having a fish inlet 3 inside the net bag 2.
