Sound generator for trapping Erythroculter ilishaeformis

Abstract

The invention discloses a sound generator for trapping Erythroculter ilishaeformis, comprising a transformer, a capacitor and a triode, wherein the output end of the oscillating coil of the transformer is connected with the capacitor in series; the central spindle nose of the control coil of the transformer is connected with the emitting electrode of the triode by resistance and the cathode of a power supply; other two ends of the control coil are connected with the base electrode of the triode respectively by a diode; the central tap of the power coil of the transformer is connected with the anode of the power supply by the shunt resistance and the switch of an ammeter; one end of the power coil is connected with the collector electrode of the triode; the other end is grounded after being connected with the collector electrode of the other triode; the input end of the power supply is connected with a voltmeter in parallel; and the shunt resistance is connected with the ammeter in parallel. The fishing device has the advantages of simple structure and small volume and is convenient to use, the shockwave thereof and Erythroculter ilishaeformis sleeping frequency generate resonance, and thus Erythroculter ilishaeformis is captured during sleeping. According to the sound generator, the living habit of the Erythroculter ilishaeformis is not affected, and labor intensity is low during fishing.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping cockroaches. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Red carp with cocked mouth, commonly known as big white fish, cocked mouth, cocked shell, white silk, Xingkai big white fish, cocked scorpion, stinging fish, cocked white, white fish, pouting fish, etc. Larger in size, the largest weighs 10-16 kg. The body is slender, flat on the sides, in the shape of willow leaves. The back of the head is straight and the back of the head is raised. The mouth is superior, and the mandible is thick and sharply upturned, vertical in front of the mouth, so that the cleft of the mouth is vertical. The eyes are large and round. The scales are small. The lateral line is obvious, the front part is slightly upward curved, and the rear part traverses the side of the body slightly below ...

AI Technical Summary

Problems solved by technology

It is not possible to specialize in catching red bream. 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 fish caught are very It is easy to be injured or missed catch, and the 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; The water is shallow, 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 red bream is low
