Description

An easy-to-catch eel trap Technical Field

[0001] This utility model relates to the field of eel trap technology, specifically to an easy-to-catch eel trapping device. Background Technology

[0002] A swamp trap is a fishing gear specifically designed for catching swamp eels, commonly known as a "haozi" or "swamp cage." Traditional swamp traps are made of materials such as bamboo strips or plastic, and are mostly cylindrical in shape, thicker at one end, and equipped with barbs (commonly called "sumata") to prevent eels from swimming out once inside. Using a swamp trap is relatively simple. It is usually placed in waters where swamp eels are active, such as lakes, ponds, and river branches, in the evening. Bait, such as poultry entrails, eggshells, clam meat, or earthworms, is placed inside to attract the eels. When setting it, the trap is placed horizontally in the water at least one meter from the shore, with the part above the water covered with aquatic plants to simulate a natural environment. The trap is retrieved the next morning.

[0003] As shown in Figure 5, existing eel traps are supported in the middle by multiple frame-shaped steel wires (indicated by arrow A in Figure 5), and both ends are tied with ropes. In use, the eel trap is placed in water with one end remaining above the surface for the eels to breathe. While this type of trap is easy to fold and open, it has a drawback: because the net is soft, it bends and folds when opened. Therefore, after placing the trap in water, it needs to be covered with aquatic plants or other heavy objects for support; otherwise, the net is prone to collapse. To address this, we propose a more convenient eel-catching device. Summary of the Invention

[0004] This invention provides an easy-to-catch eel trapping device that keeps the support net in a supported state at all times, preventing the support net from collapsing and deforming. Moreover, the support net is easy to store, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A catching device for catching eels is designed, including a support rod, a support tube movably sleeved on the support rod, both ends of the support rod being located outside the support tube, and multiple strip rods parallel to each other on the outer periphery of the support tube. At least two annular seats are provided from one end of the support tube to the other end, and multiple elastic support rods inclined in the same direction are rotatably connected to the edges of the annular seats. The strip rods are rotatably connected to the ends of the elastic support rods respectively. When the support tube moves back and forth along the support rod, the multiple strip rods simultaneously retract or open towards the support tube. When the elastic support rods are nearly perpendicular to the axis of the support tube, the ends of the support tube and the support rod are fixed by a positioning device. A support net is provided outside the strip rods, and multiple first conical nets are provided on the support net. The end of the support net away from the positioning device is connected to a collection net.

[0006] Preferably, the collection net has a strip-shaped structure with a binding rope threaded through its end to secure the collection net.

[0007] Preferably, a second conical mesh is provided inside the end of the collecting net body near the supporting net body.

[0008] Preferably, the smaller diameter end of the second conical net faces outward from the collecting net body, and a ring-shaped tightening rope is threaded through the end of both the second and first conical nets. At least two symmetrically arranged connecting ropes are connected to the tightening ropes, and the connecting ropes are respectively connected to the supporting net body and the collecting net body.

[0009] Preferably, the positioning device includes a connecting sleeve coaxially disposed on the end of the support tube, the connecting sleeve having a bayonet, the surface of the support rod near the connecting sleeve having an opening, a limiting piece being provided in the opening, the limiting piece being connected to an elastic device located inside the support rod, the limiting piece being always located outside the opening under the action of the elastic device, and the end of the support net body away from the collection net body being connected to the connecting sleeve.

[0010] Preferably, the elastic device includes a U-shaped spring sheet, the end of which is connected to a limiting piece.

[0011] Preferably, the side of the limiting piece facing the support tube is inclined.

[0012] Preferably, a limiting seat is provided at the end of the support rod near the limiting piece.

[0013] Preferably, the surface of the support rod is provided with a groove parallel to its axis, and a slider is provided inside the support tube and is movably placed in the groove.

[0014] Compared with existing technologies, this utility model, when in use, places the supporting net portion of the trapping device inside the breeding pond, and places the end of the collection net on the bank. The eels will enter the supporting net from the first conical net, and then enter the collection net from the second conical net. In the eel trapping device proposed in this application, the supporting net is supported by strip rods, ensuring that the supporting net remains open in the water, without tilting or deforming.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Referring to Figures 1 to 4, this utility model provides a technical solution: a catching device for catching eels, including a support rod 5, a support tube 8 movably sleeved on the support rod 5, allowing the support tube 8 to slide freely back and forth along the support rod 5, both ends of the support rod 5 are located outside the support tube 8, and multiple strip rods 9 are arranged parallel to each other on the outer periphery of the support tube 8.

[0024] As shown in Figure 2, at least two annular seats 10 are provided from one end of the surface of the support tube 8 to the other end. When there are two annular seats 10, the two annular seats 10 are distributed at both ends of the support tube 8. However, when the number of annular seats 10 is ≥3, two of the annular seats 10 are distributed at both ends of the support tube 8, and the remaining annular seats 10 are distributed in the middle of the support tube 8.

[0025] Multiple elastic support rods 14 inclined in the same direction are rotatably connected to the edge of the annular seat 10. Strip rods 9 are rotatably connected to the ends of the elastic support rods 14. Since the support tube 8 can slide freely on the support rod 5, when the support tube 8 moves back and forth along the support rod 5, the elastic support rods 14 rotate around the annular seat 10, causing the angle between the elastic support rods 14 and the support tube 8 to increase or decrease. This causes the multiple strip rods 9 to simultaneously converge or expand towards the support tube 8. As shown in Figure 3, it should be noted that three annular seats 10 are sufficient. The elastic support rods 14 located in the middle of the support tube 8 are used to support the strip rods 9, preventing the strip rods 9 from bending in the middle due to their large length.

[0026] When the elastic support rod 14 is nearly perpendicular to the axis of the support tube 8, that is, when the distance between the strip rod 9 and the support tube 8 is at its maximum, the end of the support tube 8 and the support rod 5 are fixed by a positioning device. As shown in Figure 2, the positioning device includes a connecting sleeve 16 coaxially disposed on the end of the support tube 8. The connecting sleeve 16 is provided with a bayonet 15. The surface of the support rod 5 near the connecting sleeve 16 is provided with an opening 17. A limiting piece 6 is provided in the opening 17. The limiting piece 6 is connected to an elastic device located inside the support rod 5. The elastic device includes a U-shaped spring piece 7. The end of the U-shaped spring piece 7 is connected to the limiting piece 6. Under the action of the elastic device, that is, under the action of the U-shaped spring piece 7, the limiting piece 6 is always located outside the opening 17.

[0027] It should be noted that the side of the limiting piece 6 facing the support tube 8 is inclined. When the connecting sleeve 16 moves towards the limiting piece 6, the limiting piece 6 and the connecting sleeve 16 are squeezed together, so that the limiting piece 6 retracts into the opening 17. When the limiting piece 6 moves to the bayonet 15, the limiting piece 6 automatically springs into the bayonet 15. At this time, each bar rod 9 is opened to the maximum. When each bar rod 9 is to be stored, simply press the limiting piece 6 to let it disengage from the bayonet 15.

[0028] In order to enable the support tube 8 to slide stably on the surface of the support rod 5 without rotating, as shown in Figure 3, a groove 19 parallel to its axis is provided on the surface of the support rod 5, and a slider is provided in the support tube 8 and is movably placed in the groove 19.

[0029] Furthermore, the strip rod 9 is provided with a support mesh 4 on the outside, and each elastic support rod 14 has a certain elasticity. When the limiting piece 6 is placed in the slot 15, the strip rod 9 supports the support mesh 4. Due to the compression of the support mesh 4 on the elastic support rod 14, the elastic support rod 14 will bend to a certain extent, so that the elastic support rod 14 can support the support mesh 4 and prevent the support mesh 4 from wrinkling.

[0030] Multiple first conical nets 3 are provided on the support net body 4, as shown in Figure 1. The first conical nets 3 are distributed between the strip rods 9. The small ends of the first conical nets 3 are all located inside the support net body 4. The end of the support net body 4 away from the positioning device is connected to the collection net body 1. The end of the collection net body 1 close to the support net body 4 is provided with a second conical net 13, as shown in Figure 2. The end of the second conical net 13 with a smaller diameter faces the outside of the collection net body 1. A ring-shaped tightening rope 12 is threaded through the end of the second conical net 13 and the end of the first conical net 3. At least two symmetrically arranged connecting ropes 11 are connected to the tightening ropes 12 respectively. The connecting ropes 11 are connected to the support net body 4 and the collection net body 1 respectively.

[0031] The tightening rope 12 prevents the openings at the ends of the second conical net 13 and the first conical net 3 from being torn, and the connecting rope 11 stretches the second conical net 13 and the first conical net 3 to prevent them from deforming and wrinkling. The second conical net 13 and the first conical net 3 are like barbels, which are used to prevent the eels from swimming back.

[0032] Furthermore, the collection net 1 has a strip-shaped structure with a binding rope 2 threaded through its end for securing it. As shown in Figure 4, in actual use, due to the relatively long length of the collection net 1, when the tail opening of the collection net 1 is opened, bait can be placed inside the collection net 1. The supporting net 4 of the baiting device is placed in the breeding pond, with the end of the collection net 1 placed on the bank. Eels will enter the supporting net 4 through the first conical net 3, and then enter the collection net 1 through the second conical net 13. The eels can also breathe air from the top of the collection net 1. The supporting net 4 is supported by the strip rod 9, ensuring that the supporting net 4 remains open in the water, without tilting or deforming.

[0033] Based on the above embodiments, further optimizations can be made. As shown in Figures 2 and 3, a limiting seat 18 is provided at one end of the support rod 5 near the limiting piece 6. In actual use, the limiting seat 18 can be used as a handle, that is, the operator can grasp the limiting seat 18 with one hand and pull the connecting sleeve 16 towards the limiting piece 6 with the other hand.

[0034] Based on the above embodiments, it should be further explained that, in actual use, as shown in Figure 2, the end of the support net body 4 away from the collection net body 1 needs to be connected to the connecting sleeve 16, so that the support net body 4 and the connecting sleeve 16 are connected as a whole, and the end of the connecting sleeve 16 and the bayonet 15 should protrude outside the end of the support net body 4.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
