Sonic-sensing lobster catching cage

Abstract

A sonic-sensing lobster catching cage is characterized in that a cage frame is round, the outer periphery of the cage frame is covered with a wire net, the middle of the front of the cage frame covered with the wire net is provided with a lobster entry, reverse steel wires which extend inward are connected to the lobster entry, a waterproof tiered box is disposed at the rear end of the cage frame covered with the wire net, the waterproof tiered box is fixed through stay ropes, a lobster acoustic apparatus, a lobster sonic apparatus, a lobster frequency modulator, a far-sonic apparatus and a sensor are disposed in inner cavities of the waterproof tiered box, an acoustic wire of the lobster acoustic apparatus is connected with a sonic wire of the lobster sonic apparatus, the sonic wire of the lobster sonic apparatus is connected with a frequency modulation wire of the lobster frequency modulator, a frequency modulation wire of the lobster frequency modulator is connected with a far-sonic wire of the far-sonic apparatus, and the far-sonic wire of the far-sonic apparatus is abutted to a sensing wire of the sensor.

Description

technical field [0001] The invention relates to a lobster catching cage, in particular to a sonar sensing lobster catching cage, which belongs to the technical field of sonar lobster catching cages. Background technique [0002] At present, when people are catching lobsters, they generally use hanging nets and cages, and put the bait that lobsters like into the water in hanging nets and cages to catch them. The special fragrance and the lack of auxiliary equipment can easily lead to high labor intensity, small catches and poor lobster catching effect. Contents of the invention [0003] The purpose of the present invention is to provide a sonar sensing lobster cage with simple structure, small size, easy to carry, more lobsters, and good lobster catching effect, which overcomes the limitations of the existing lobster hanging nets and cages. The above-mentioned defects that exist. [0004] The technical solution adopted by the present invention to solve its technical probl...

AI Technical Summary

Problems solved by technology

[0005] Beneficial effects of the present invention: Since the present invention adopts the above-mentioned scheme, after the lobster cage with sonar sensor enters the water, the sonic device, sonar device, frequency modulator, and remote device installed in the cage will pass through The sensor emits sound waves and sonar. Under the action of the frequency modulator, the sensor works. The sound waves and sonar emitted by the sensor have the same audio frequency as the sonic waves of the lobster. After receiving the sonic sonar emitted by the sensor, the lobsters within a radius of tens of meters will all Crawl quickly and get into the cage without knowing it. Because the entrance of the cage is big and small, all the lobsters entering the cage are caught, and the purpose of the present invention is achieved. The present invention has simple structure, small size The advantages of being small, easy to carry, catching many lobsters, and good lobster catching effect effectively overcome the existing hanging nets and cages that have no special fragrance, and there are no other auxiliary equipment, which may easily cause labor intensity and catch lobsters. Defects of small quantity and poor lobster catch effect
