Sound generator for trapping carps

Abstract

The invention discloses a sound generator for trapping 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 carps has the advantages of simple structure, small volume, convenient use, capability of trapping the carps in the dreams due to resonance generated by a shock wave and a sleeping frequency of the carps, no influence on the life habit of the carps and low labor intensity when fishing.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping carp. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Carp is a benthic omnivorous fish that eats both meat and vegetables. It has a wide range of baits, well-developed kiss bones, and often feeds on mud. Carp is also a low-level temperature-changing animal, and its body temperature changes with the change of water temperature. It does not need to consume energy to maintain a constant body temperature, so the total amount of bait and food it needs is not large. At the same time, carp, like most freshwater fish, is a stomachless fish species with a thin and short intestinal tract and a fast metabolism, so the eating habit is to eat less and frequently. The digestive function of carp is greatly related to the water temperature, and the seasonality of feeding is very strong. In...

Problems solved by technology

Carp cannot be exclusively caught. It is inefficient to use a cast net to catch fish in a wide 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 carp is low
