Sound wave generator for trapping silver carp

Abstract

The invention discloses a sound wave generator for trapping silver carp. The sound wave generator for trapping the silver carp comprises a transformer, a capacitor and a triode; the output end of the oscillating coil of the transformer is connected in series with the capacitor, the center tab of the control coil of the transformer is connected with the cathode of a power supply and the emitter of the triode through resistors, and the other two ends of the control coil are connected with the base of the triode through diodes respectively; and the center tab of the power coil of the transformer is connected with the anode of the power supply through a shunt resistor of an ampere meter 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 ampere meter is connected in parallel to the shunt resistor. The sound wave generator for trapping the silver carp has simple structure and small volume, and is convenient to use; and the oscillating wave of the sound wave generator generates resonance with the sleeping frequency of the silver carp, so that the silver carp is trapped in sleeping. The sound wave generator does not affect the living habit of the silver carp, and has low labor intensity during fishing.

Description

technical field [0001] The invention relates to a sonic fishing device, in particular to a sonic generator for trapping silver carp. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Silver carp is also known as silver carp, water carp, jumping carp and silver carp. The side of the body is flat, slightly taller, fusiform, the head is big and the snout is short, the mouth is wide, the eyes are small, the scales are very thin, the body is silvery white, and the abdomen has flesh ribs. Silver carp is a large-scale freshwater fish raised artificially. It grows fast, has few diseases, and has a high yield. It is mostly mixed with grass carp and carp. Its meat is tender and nutritious, and it is one of the excellent fish species that are more suitable for breeding. Silver carp is a pelagic fish. In the three seasons of spring, summer and autumn, most of the time they swim in the middle and upper layers of the ...

AI Technical Summary

Problems solved by technology

Catching silver carp cannot be done exclusively. It is inefficient to use a cast net to catch 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 caught fish are easily injured or missing catch, the fish that escape due to injury or missing 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, it is difficult to use the net, and the efficiency of catching silver carp is low
