Visible acoustic-sonic grass carp trapping net cage

Abstract

Disclosed is a visible acoustic-sonic grass carp trapping net cage. A front sliding door and a rear sliding door are arranged at the front and the back of a net wall respectively. Two ends of the front and the back sliding doors are connected with a front door-pulling rope and a back door-pulling rope respectively. A fish taking box is connected with the net wall at the rear end of the back sliding door and is of a narrow long box body. A fish pulling plate is arranged in the fish taking box and capable of sliding back and forth in the narrow long box body. A fish inlet reviewer is mounted on one side of the net wall. A video lens, a fluorescent lamp and an acoustic-sonic are arranged in inner chambers of the fish inlet reviewer respectively. A video importing and storing device is connected to the video lens and a signal wire. A signal wire plug is connected to the signal wire and is in abutted connection with a port of a computer.

Description

technical field [0001] The invention relates to a net cage for trapping grass carp, in particular to a net cage for trapping grass carp with visible sonic sonar, and belongs to the technical field of net cages for fishing with visible sonic waves. Background technique [0002] At present, when people catch grass carp on the breeding water surface, they usually use pull nets for fishing. Due to the large water surface for grass carp breeding, and the complex bottom of the water, there are many pits and ditches, it is difficult to catch many grass carp on the breeding water surface by using pull nets. Not only is the labor intensity high, grass carp that have not been caught are easily injured and frightened, which affects their normal growth. Contents of the invention [0003] The object of the present invention is to provide a kind of visible sonic sonar grass carp trapping net cage with low labor intensity, no frightening and no damage to the caught fish, good fishing eff...

Problems solved by technology

[0005] Beneficial effects of the present invention: the present invention is designed according to the physiological and living habits of grass carp, using the law of activity of grass carp, the principle of sound transmission, and sound wave guidance. , coupled with the addition of sonic sonar and visual functions, a large range of natural fish news will be formed after more than ten days. When fishing, just open the fish to enter the observation mirror and sonar It emits strong sonic sonar and spreads rapidly to far waters. Grass fish will feel hungry after receiving the eating audio from the sonic sonar, and all kinds of grass fish will quickly The feeding frequency of the sonar sonar enters the trapping net cage to snatch the feed. The fisherman only needs to observe the grass carp entering situation according to the video lens. After reaching the required catch, he can close the front sliding door and open the rear sliding door to catch. Fish has achieved the purpose of the present invention. The present invention has the advantages of reasonable design, compact structure, ingenious fishing, low labor intensity, no frightening of fish, no harm to grass carp, good fishing effect, and high catch rate. The disadvantages of the existing dragnet grass carp catching are few, labor intensity is high, grass carp is easily injured, easily frightened, and affects its growth
