Acoustic wave generator for trapping red coat

Abstract

The invention relates to an acoustic wave generator for trapping a red coat. The generator for trapping the red coat comprises a transformer, a capacitor and a triode, wherein the output end of an oscillating coil of the transformer is connected with the capacitor in series; a center shaft head of a control coil of the transformer is connected with the negative electrode of a power supply and an emitter electrode of the triode through a resistor; the other two ends of the control coil are connected with a base electrode of the triode through the diode; a center tap of a power coil of the transformer is connected with the positive electrode of the power supply through a shunt resistor of an ampere meter and a switch; one end of the power coil is connected with a collector electrode of the triode, and the other end is connected with the collector electrode of another triode and then is grounded; a voltmeter is connected with the input end of the power supply in parallel; and the ampere meter is connected with the shunt resistor in parallel. The fishing device has the advantages of simple structure and small size, is convenient for use; because oscillating waves of the fishing device are resonant with the sleep frequency of the red coat, the red coat is caught while sleeping without influencing the life habit of the red coat; and the labor intensity is low when people fish.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping golden thread fish. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Golden thread fish, common names: Hongshan, Hongge carp, Diaosan, Tuosan, Guasan, Huangdu. The body is elongated, flattened, and the dorsal and ventral margins are blunt. The general body length is 19-31 cm, the weight is 50-150 grams, the snout is blunt and pointed, and the mouth is slightly inclined. There are five large conical teeth at the front of the upper jaw. There are small conical teeth on the sides. The body is covered with thin ctenoid scales, the whole body is dark red, the abdomen is lighter, there are 6 obvious yellow longitudinal bands on both sides of the body, the dorsal fin is long; the caudal fin is forked, and the end of the upper lobe is extended into a filament . The upper edge of the d...

AI Technical Summary

Problems solved by technology

It is not possible to specialize in catching golden thread fish. It is inefficient to use a cast net to fish in a wider water surface. It is labor-intensive to use a pull net to fish, and it is very inconvenient to catch fish. When using a cast net or a pull net, the fish caught are easy Injured or missed catch, fish that escape due to injury or missed catch will be frightened, thus affecting the normal growth of fish and the occurrence of various fish diseases; , there are many aquatic plants and rocks at the bottom of the river, it is difficult to use the net, and the efficiency of catching gold thread fish is low
