Visual sonar lobster fishing net

Abstract

Disclosed is a visual sonar lobster fishing net. A lobster inlet is arranged at the front end of the lobster fishing net, and the lobster inlet extends inwards to be connected with an inner inverted beard. A shrimp entering observation mirror is mounted on the upper side of the front end of the lobster fishing net, a video lens, a light dispersing lamp and a shrimp acoustic wave sonar are mounted in an inner cavity of the shrimp entering observation mirror, a video transmission line is connected to the upper end of the video lens, a signal connecting line is connected on the video transmission line, a video plug is connected on the signal connecting line, and the video plug is connected with a port of a computer.

Description

technical field [0001] The invention relates to a lobster catching net, in particular to a visual sonar lobster catching net, which belongs to the technical field of sonar visual lobster catching net. Background technique [0002] At present, when people catch lobsters, the main fishing tools used are net pockets, end nets, lifting nets and other fishing tools. Lobster likes to live on complex water surface with many grass and rocks, so it is difficult for the above three nets to go to the bottom of the water, and because of the large water entry area, the water resistance is large when the water surface is raised, which is easy for the lobster to escape, resulting in a low catch. , The capture effect is poor. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a visual type sonar lobster catching net that is easy to fold, is easy to carry, has low labor intensity, high catch and good lobster fishing effect, and overcomes the existing prob...

Problems solved by technology

[0005] Beneficial effects of the present invention: because the present invention adopts the above scheme, after the lobster catching net enters the water, the shrimp can be opened to enter the observation mirror and the shrimp sonic sonar, and the shrimp sonic sonar will emit the shrimp sonic , and quickly spread to various aquatic plants, reeds, rock caves, caves and rock formations. After the lobsters received the sound waves of shrimp sonar, due to the effect of the oscillation wave frequency, they had a strong sense of hunger and swam to Pursue sound waves and sonar oscillating frequency waves, and enter the lobster fishing net unconsciously. Because the entrance of the net is large in front and small in the rear, the lobster in the net cannot escape. The catcher only needs to observe the shrimp entering through the video lens. The present invention has the advantages of being easy to fold, easy to carry, low labor intensity, high catch rate, and good lobster fishing effect, and effectively overcomes the existing net bags, end nets, lifting When the net is catching lobster, it is easy to make the lobster escape, resulting in the defects of low catch rate and poor catch effect
