Problems solved by technology

It is not possible to specialize in fishing perch. 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 caught fish are easily injured

Abstract

The invention discloses a sound generator for trapping weever, 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 a resistance and the cathode of a power supply; the other two ends of the control coil are respectively connected with the base electrode of the triode 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; after the other end of the power coil and the collector electrode of the other triode are grounded, the input end of the power supply is connected with a voltmeter in parallel; and the shunt resistance is connected with the ammeter in series. The fishing device has the advantages of simple structure, small volume and convenient use, and the shockwave thereof and weever sleeping frequency generate resonance, thus the weever is captured in the sleep state. The invention does not affect the living habit of the weever and has the advantage of low labor intensity during fishing.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping perch. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Bass, the body is elongated and flattened, generally 30-40 cm in length, 400-800 g in weight, and slightly concave between the eyes. There are 4 raised lines in between. Mouth large, lower jaw longer than upper jaw. The snout is pointed, the teeth are small, and they are arranged in villi-like dental bands on the two jaws, the vomer and the palatine. The posterior margin of the preopercle has fine serrations, and the corners and lower margins have blunt spines. The lateral line is completely parallel to the dorsal edge of the body, the body is covered with fine ctenoid scales, the cortex is rough, the scales are not easy to fall off, and the back of the body is blue-gray. The ventral side is grayish white, with black sp...
