[0002] Modern fishing nets are mainly processed with raw materials such as polyethylene and nylon. They have a longer service life and higher fishing efficiency, and are classified according to different usage methods. For example, the throwing net used in traditional fishing, the trawl net powered by a boat, the drift net that catches fish by hanging gills with different mesh sizes, etc. These nets are woven with different mesh sizes and net lines of different materials for different fishing targets.

[0003] The patent document with the publication number of CN220490728U discloses an anti-corrosion detection device for polyethylene fishing nets, including a detection box. There is a box cover at the top of the detection box. A motor is fixedly installed in the middle of the top of the box cover. The transmission shaft of the motor passes through the box cover and is fixedly connected to a rotating rod arranged inside the detection box. A filter box is fixedly installed at the bottom of the rotating rod; the utility model has the advantages that the fishing net can be fully immersed in the corrosion liquid, the contact time between the corrosion liquid and the fishing net is increased, it is convenient for the fishing net to be fully mixed with the corrosion liquid, and the anti-corrosion detection effect of the fishing net itself is prevented from being affected.

At this time, the electric push rod 26 is started to drive the lifting frame 25 to rise in the direction of the electric inspection guide sleeve 27 and the guide rod 28 until the mounting frame 2 is higher than the detection box 1. At this time, the second threaded rod 31 is driven by the second motor 32, so that the mounting frame 2 slides on the linear slide rail 29 through the chute 30, and the mounting frame 2 is above the detection box 1. Further, the mounting frame 2 is lowered by the electric push rod 26 until the box cover 21 is covered on the detection box 1, so that the fishing net 11 is immersed in the corrosive liquid. Further, the first motor 16 drives the worm 15, and the worm 15 drives the annular slide block 4 to rotate in the annular slide rail 3 through the cooperation with the worm gear 14, so that the rectangular frame 5 rotates, and further the fishing net 11 rotates in the detection box 1. The air pump 19 continuously supplies gas to the aeration box 17 through the pipeline 20, and the gas drives the corrosive liquid to blow towards the fishing net 11 through the nozzle 18, improving the contact effect of the fishing net 11. The exploded air is discharged through the gap between the box cover 21 and the detection box 1, so as to perform anti-corrosion detection on the fishing net 11. During the detection, the corrosion situation of the fishing net 11 can be continuously observed through the observation window 24.
