Sound generator for trapping Chinese hooksnout carp

Abstract

The invention discloses a sound generator for trapping a Chinese hooksnout carp, which comprises a transformer, a capacitor and triodes. An output end of an oscillating coil of the transformer is connected in series with the capacitor; a central axle head of a control coil of the transformer is connected with a negative pole of a power source and emitters of the triodes through resistors; the other two ends of the control coil are respectively connected with base electrodes of the triodes through diodes; a centre tap of a power coil of the transformer is connected with a positive pole of the power source through a shunt resistor of an ampere meter and a switch; one end of the power coil is connected with a collector of a triode and the other end of the power coil is connected with a collector of another triode and then is grounded; a voltmeter is connected in parallel with a power input end; and the ampere meter is connected in parallel with the shunt resistor. The device for trapping the Chinese hooksnout carp has the advantages of simple structure, small volume and convenient use. Resonance is generated between the shock waves of the device and the sleeping frequency of the Chinese hooksnout carp, so that the Chinese hooksnout carp is trapped in sleep. The device for trapping the Chinese hooksnout carp does not influence the life habit of the Chinese hooksnout carp and has the advantage of low labor intensity when trapping the Chinese hooksnout carp.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping horse mouth fish. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] The horse mouth fish belongs to Cyprinidae, Cyprinidae, and the horse mouth fish. Commonly known as: peach blossom fish, mountain fish, pit crawling, wide mouth, big mouth grill, pull mouth woman, red car public. The body is long and flattened, with a round abdomen. The snout is long and the mouth is large; the cleft of the mouth is inclined upwards, and the rear end of the mandible extends to the edge of the eye. The eyes are equal in size. The lateral line is complete, the front part bends to the side of the body, and the back part extends upwards to the middle of the caudal peduncle. The back of the body is gray-black, the abdomen is silvery-white, there are light blue vertical stripes on the side of the b...

AI Technical Summary

Problems solved by technology

It cannot specialize in catching horse mouth 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 catch 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 horse mouth fish is low
