Acousto-optic-electric comprehensive fish driving device

Abstract

The invention discloses an acousto-optoelectronic comprehensive fish-dispelling instrument, which relates to an acousto-optoelectronic comprehensive instrument that is used for dispelling fish, and is characterized in that the output voltage value of the direct current power supply of the instrument is less than or equal to 24V; the input terminal of a pulse generator is electrically connected with the direct current power supply, and the output terminal of the pulse generator outputs a pulse with a voltage value less than or equal to 24V; the input terminal of a pulse booster is electrically connected with the output terminal of the pulse generator, the output terminal of the pulse booster outputs a pulse with the voltage value more than or equal to 100V, an underwater electrode comprises two beam electrode long lines, the input terminal of a pulse power generator is electrically connected with the direct current power supply, while the output terminal of the pulse power generator outputs a pulse with the voltage value less than or equal to 24V; a flash generator comprises a transparent casing and a luminescent lamp, the input terminal of a terrifying sound generator is connected with the direct current power supply, while the output terminal of the terrifying sound generator outputs prerecorded cry sound signals sent out by various fishes when being electrically shocked; an underwater speaker is used for displaying the cry sound signals which are sent out by the fishes when being electrically shocked and are output by the terrifying sound generator; and the underwater electrode, the underwater speaker, and the flash generator are respectively and fixedly connected with the bottom of a fishing net.

Description

technical field [0001] The invention relates to an acousto-optic comprehensive instrument for repelling fish, in particular to an acousto-optic comprehensive instrument for urging benthic fish dormant in the mud to escape from the mud layer. Background technique [0002] Bottom-dwelling fish such as yellow catfish, loach, and rice field eel have high nutritional value and delicious taste, and are very popular in domestic and foreign markets. The artificial breeding of this kind of fish has been popularized in the north and south of the country, but in order to reduce the cost of breeding, most of them are cultured in natural waters or earthen ponds. Since bottom fishes, no matter they are fry or adult fish, have special living habits of sticking to mud or drilling mud, when raising bottom fish such as yellow catfish, loach, and eel, there is generally a problem of difficulty in catching. Among the currently used methods of catching, the efficiency of catching with conventio...

Problems solved by technology

Due to the special living habits of bottom dwelling fish, whether fry or adult fish, sticking to mud or drilling mud, it is common to have difficulties in catching bottom dwelling fish such as yellow catfish, loach, and eel.

Among the currently used starting methods, the efficiency of using conventional nets is very low, forcing farmers to adopt the method of manual capture after pumping water. This method is labor-intensive and consumes electricity and water, so the cost is quite high

However, most of the existing auxiliary electric fishing equipment uses continuous AC, DC, or high-voltage switching of DC into high-voltage pulses to emit electric fields into the water to shock fish. This method is only suitable for wild waters. have a devastating impact on the survival of individuals in the water and put those who work in the water at risk

At present, there is no fish repelling instrument that integrates sound and light
