Description

Technical Field

[0001] The utility model relates to the technical field of fishing gear, in particular to a sinking depth adjusting device for a fishing net. Background Art

[0002] A fishing net is a net used for fishing. In ancient times, people used coarse cloth and hemp as raw materials and made fishing nets by bundling and rolling. Although this kind of fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of the fishing industry, the objects of fishing are not only fish, but also the fishing tools have kept pace with the times. Fishing nets are divided into gillnets, trawls, purse seines, pound nets and set nets in terms of function. High transparency (partially nylon nets) and strength, good impact resistance, wear resistance, mesh size stability and softness, and appropriate breaking elongation (22% - 25%) are required. It is processed from monofilaments, multifilament twisted yarns or monofilaments through weaving, primary heat treatment, dyeing and secondary heat treatment.

[0003] Application No.: CN202221452759.X discloses a fishing net with a function of adjustable sinking position, which relates to the technical field of fishing nets. In order to solve the problem that when the existing fishing nets are in use, most of the suspended positions are relatively fixed and cannot meet the fishing operations at different depths. The air inlet pipes are installed on both sides of the upper end surface of the suspended connecting rod body, and there are two suspended connecting rod bodies. Both of the air inlet pipes are rotationally connected to the suspended connecting rod body through the threaded walls, and the threaded walls are integrally formed with the inner wall of the suspended connecting rod body. The first pumping mechanism is installed on the lower end surface of the suspended connecting rod body. There are three first pumping mechanisms, and all three first pumping mechanisms are fixedly connected to the suspended connecting rod body. The lower end surfaces of all three first pumping mechanisms are provided with conveying rod bodies, and there are three conveying rod bodies. The lower end surfaces of all three conveying rod bodies are provided with storage mechanisms and penetrate and extend into the inner wall of the storage mechanism.

[0004] However, when the above device is in use, the up and down adjustment of the position of the fishing net main body is achieved by the entry or output of gas and liquid. However, the air inlet end of the above device must be arranged above the water surface, which has certain limitations. Therefore, a sinking depth adjusting device for a fishing net needs to be proposed. Summary of the Utility Model

[0013] The connector includes a communicating pipe penetrating through the outer side wall of the installation box. One end of the communicating pipe is communicated with an air inlet pipe. The other end of the communicating pipe is communicated with a gas guide pipe. A control valve is fixedly installed on the communicating pipe. The air outlet of the high-pressure gas cylinder is communicated with the air inlet pipe. The gas guide pipe is communicated with the gas guide hose.

[0014] For adjusting the volume of the gas collecting balloon to facilitate the floating treatment of the fishing net main body, install the high-pressure gas cylinder into the installation box so that the air outlet of the high-pressure gas cylinder is communicated with the air inlet pipe. When floating treatment is required for the device, start the control valve so that the gas in the high-pressure gas cylinder is transported to the gas collecting balloon through the air inlet pipe, the communicating pipe, the gas guide pipe and the gas guide hose, thereby adjusting the volume of the gas collecting balloon and facilitating the floating treatment of the fishing net main body.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up a floating component, the high-pressure gas cylinder is installed in the installation box, making the gas outlet of the high-pressure gas cylinder communicate with the inlet pipe. When it is necessary to float the device, the control valve is activated, so that the gas in the high-pressure gas cylinder is transported to the balloon through the inlet pipe, the connecting pipe, the guide pipe and the gas guide hose, thereby adjusting the volume of the balloon and facilitating the floating treatment of the main fishing net body.

[0017] 2. By setting up a sinking component, when sinking is required, the two-way pump transports the external water source to the sinking water tank through the inlet pipe and the guide pipe. When floating is required, the two-way pump discharges the water in the sinking water tank through the inlet pipe and the guide pipe. BRIEF DESCRIPTION OF THE DRAWINGS
