Eel fishing sound wave generator

Abstract

The invention relates to an eel fishing sound wave generator which is provided with a transformer, a capacitor and triodes; the output end of an oscillating coil of the transformer is connected in series with the capacitor; a central shaft head of a control coil of the transformer is connected with a cathode of a power supply and emitting electrodes of the triodes by a resistor; another two ends of the control coil are respectively connected with base electrodes of the triodes through diodes; a central shaft head of a power coil of the transformer is connected with an anode of the power supply by a shunt resistor of an amperemeter and a switch; one end of the power coil is connected with a collecting electrode of one triode, and the other end is grounded after being connected with a collecting electrode of the other triode; the input end of the power supply is connected in parallel with a voltmeter; and the shunt resistor is connected in parallel with the amperemeter. The fishing device has the advantages of simple structure, small size and convenient use; an oscillating wave and the sleeping frequency of an eel generate resonance so that the eel is fished during sleeping. The invention does not influence the living habit of the eel 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 eels. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Eel aliases: white eel, white eel, river eel, eel, green eel, wind steamed bun, Japanese eel, etc., eel is the meat or whole of eel, an animal of the eel family. Adult eels grow fast, round and cone-shaped in appearance, black in color and firm in body, and more artificially bred in recent years, with crispy meat. Eel is a fish that looks like a snake but has no scales. It is generally found in seas where brackish and fresh waters meet. Mainly distributed in the Yangtze River, Minjiang River, Pearl River Basin, Hainan Island and rivers and lakes in China. It is one of the famous and special breeding species in my country. Eel grows in fresh water. Our country mainly relies on the natural eel fry from the Yangtze River for artificial...

AI Technical Summary

Problems solved by technology

It is not possible to specialize in fishing eels. It is inefficient to use cast nets for fishing in a wider water surface. Fishing with drag nets is labor-intensive, and it is very inconvenient to catch fish. When using cast nets or drag nets, the caught fish are easily 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, it is difficult to use the net, and the efficiency of catching eels is low
