Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture fishing devices, specifically, to a fishing device for raising giant salamanders. Background Technology
[0002] The Chinese giant salamander is native to the central provinces of China. Its habitat is lush vegetation, excellent water quality, and regular water temperature changes throughout the year. Its production efficiency is greatly affected by water temperature in streams or rivers that do not freeze in winter.
[0003] When raising giant salamanders, it is necessary to use fishing devices to catch them. Currently, most of the fishing methods use nets. However, the mucus on the surface of giant salamanders is slippery, making it easy for them to slip out of the net, thus affecting the fishing results. How to invent a fishing device for giant salamander farming to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a fishing device for giant salamander farming, aiming to improve the current practice of using nets for catching fish, but the mucus on the surface of giant salamanders is slippery, making them easy to slip out of the net and thus affecting the catching effect.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a fishing device for raising giant salamanders, including a connecting rib and a telescopic handle set on the connecting rib. A fishing net is connected to the side wall of the connecting rib. An escape-proof net is provided on the inner side wall of the fishing net. Multiple sets of first elastic support ribs and second elastic support ribs are provided on the outer side wall of the escape-proof net. One end of each set of first elastic support ribs and second elastic support ribs is connected to the inner side wall of the fishing net.
[0007] Preferably, the first elastic support rib, the second elastic support rib, and the sidewall of the escape-proof net form a triangular shape, and both the first elastic support rib and the second elastic support rib are made of silicone material.
[0008] Preferably, the escape-proof net is arranged in the shape of an inverted frustum, and the escape-proof net has an opening.
[0009] Preferably, the bottom of the fishing net is provided with an elastic feeding net connected thereto, the side wall of the elastic feeding net is provided with a strap, and the side wall of the strap is provided with a Velcro strap.
[0010] Preferably, the escape-proof net and the fishing net have the same mesh size, and the escape-proof net and the fishing net are integrally formed.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model uses an inverted truncated cone-shaped anti-escape net and a cone-shaped entrance design to prevent the giant salamander from retreating by taking advantage of its forward movement. When the giant salamander struggles, the elastic support ribs squeeze the anti-escape net, thereby reducing the escape space and preventing the giant salamander from slipping out of the net.
[0013] 2. The elastic support rib of this utility model is made of silicone material, so that when the salamander jumps and touches the elastic support rib, it will not cause scratches to the salamander's skin. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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 scope of protection of this utility model.
[0020] Example, refer to Figures 1-3A fishing device for raising giant salamanders includes a connecting rib 5 and a telescopic handle 6 disposed on the connecting rib 5. The outer wall surface of the connecting rib 5 is smooth. A fishing net 1 is connected to the side wall of the connecting rib 5. An escape-proof net 4 is provided on the inner side wall of the fishing net 1. The escape-proof net 4 has the same mesh size as the fishing net 1 and is integrally formed with the fishing net 1. The outer side wall of the escape-proof net 4 is provided with multiple sets of first elastic support ribs 7 and second elastic support ribs 8. One end of each set of first elastic support ribs 7 and second elastic support ribs 8 is connected to the inner side wall of the fishing net 1.
[0021] The first elastic support rib 7, the second elastic support rib 8, and the side wall of the escape-proof net 4 form a triangle. Both the first elastic support rib 7 and the second elastic support rib 8 are made of silicone material.
[0022] It should be noted that: the first elastic support rib 7 is arranged longitudinally, and the second elastic support rib 8 is arranged laterally to form a triangular mesh elastic cavity. The silicone material can provide flexible wrapping to adapt to the twisting of the fish body.
[0023] The escape-proof net 4 is set in the shape of an inverted frustum and has an opening.
[0024] It should be noted that the inverted truncated cone opening utilizes the giant salamander's habit of moving forward without retreating to prevent it from escaping from the fishing net 1. When the salamander struggles and squeezes the escape-proof net 4, the first elastic support rib 7 and the second elastic support rib 8 can generate radial contraction force, forming an adaptive enveloping cavity, which greatly reduces the chance of the giant salamander escaping from the fishing net 1.
[0025] The bottom of the fishing net 1 is provided with an elastic feeding net 2 connected to it. The side wall of the elastic feeding net 2 is provided with a strap 3, and the side wall of the strap 3 is provided with a Velcro strap.
[0026] It should be noted that when it is time to release the fish, the staff will tear open the Velcro strap 3, the elastic feeding net 2 will automatically unfold, and the salamander will slide out.
[0027] Working principle: When capturing the giant salamander, the telescopic handle 6 extends to the bottom of the salamander's body, and then the net is lifted. The giant salamander slides into the bottom of the net along the inverted truncated cone anti-escape net 4. When the salamander struggles, it squeezes the anti-escape net 4, and the elastic support ribs 7 / 8 deform and contract to form an adaptive enveloping cavity. As a result, the opening is squeezed and the aperture shrinks, preventing the giant salamander's head from drilling out. When the fish is released, the staff tears open the Velcro strap 3, and the elastic feeding net 2 automatically unfolds, allowing the giant salamander to slide out.
[0028] It should be noted that the specific model and specifications need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
