Sound generator for trapping crucian carps

Abstract

The invention discloses a sound generator for trapping crucian carps, which comprises a transformer, a capacitor and a triode, wherein the capacitor is connected in series with the output end of an oscillating coil of the transformer; a central tap of a control coil of the transformer is connected with an emitting electrode of the triode by resistance and a negative electrode of a power supply, and the other two ends of the control coil are respectively connected by bases of a diode and the triode; a central tap of a power coil of the transformer is connected with a positive electrode of the power supply by a shunt resistance and a switch of an ampere meter; one end of the power coil is connected with a triode collector, while the other end is grounded after being connected with another triode collector; and a voltmeter is connected in parallel with an input end of the power supply, and the ampere meter is connected in parallel with the shunt resistance. The sound generator for trapping the crucian carps has the advantages of simple structure, small volume, convenient use, capability of trapping the crucian carps in the dreams due to resonance generated by a shock wave and a sleeping frequency of the crucian carps, no influence on the life habit of the crucian carps and low labor intensity when fishing.

Description

technical field [0001] The invention relates to a sonic fishing device, in particular to a sonic generator for trapping crucian carp. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Crucian carp is a kind of crucian carp of Cyprinidae Cyprinidae, commonly known as Xitou. Crucian carp, crucian crucian crucian carp, crucian crucian carp, crucian carp, crucian crucian carp, crucian crucian carp, boy crucian carp, etc., were called abalone and cold in ancient times. Crucian carp has a flat and tall body with a body length of 2.2-2.8 times its body height. It has a small ventral head, blunt snout, no beards, small eyes, and a row of hypopharyngeal teeth. The base of the dorsal fin is long, and both dorsal and anal fins have a thick and thick And there are rough serrated hard spines on the rear edge; the scales are larger, the lateral line scales are 27-30 pieces, the back of the body is gray-black, the side o...

AI Technical Summary

Problems solved by technology

It is not possible to catch crucian carp exclusively. 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 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 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 crucian carp is low
