Hucho taimen trapping sound wave generator

Abstract

The invention discloses a hucho taimen trapping sound wave generator. The hucho taimen trapping generator is provided with a voltage transformer, a capacitor and triodes, wherein the output end of an oscillating coil of the voltage transformer is connected in series with the capacitor, the central shaft head of a control coil of the voltage transformer is connected with a power supply cathode and the emitters of the triodes through resistors, and the other two ends of the control coil are connected with the bases of the triodes through diodes respectively; and the central shaft head of a power coil of the voltage transformer is connected with a power supply anode through a shunt resistor of an ammeter and a switch, one end of the power coil is connected with the collector of one triode, the other end of the power coil is connected with the collector of the other triode and then grounded, a voltmeter is connected in parallel at the input end of the power supply, and the ammeter is connected in parallel on the shunt resistor. The trapping device has the advantages of simple structure, small volume and convenient use; and the oscillating wave of the device and the sleep frequency of hucho taimen generate resonance so that the hucho taimen is trapped in sleep. The hucho taimen trapping sound wave generator does not affect the life habit of the hucho taimen, and has low labor intensity during trapping.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping salmon. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] The body of Zheluo fish is long, slightly flattened and cylindrical. The head is flat, the snout is pointed, the mouth is large, and the end is positioned. Maxilla prominent, free, extending posteriorly to posterior edge of eye. There are sharp teeth inclined inward on the upper and lower jaws, vomer and tongue. The scales are very small, elliptic, and the rings on the scales are arranged very clearly, without radial grooves. The lateral line has 193-242 scales, and the lateral line is complete. The adipose fins are more developed. The back is blue-brown, and the abdomen is silvery white. There are numerous dense, miliary-like dark black cross-shaped spots on the head and sides of the body. During the spawning period...

AI Technical Summary

Problems solved by technology

It is not possible to specialize in the fishing of jellyfish. 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 a net, and the efficiency of catching salmon is low
