Far wave voice frequency carp trapping acoustic wave device

Abstract

The invention discloses a far wave voice frequency carp trapping acoustic wave device. A far wave voice frequency transformer is provided with a far frequency oscillating coil, a voice wave control coil and a far wave power coil. A frequency modulation capacitor is connected to an output end of the far frequency oscillating coil in series, and the far frequency oscillating coil has two output ends. The voice wave control coil is provided with two symmetrical coil bodies, a center tap of the voice wave control coil is jointly connected with emitters of two sets of sonar triodes through a resistor and a negative electrode of a power source, the other two ends of the voice wave control coil are respectively connected with bases of the triodes through diodes and connected with bases of the triodes through diodes, the far wave power coil is provided with two symmetrical coil bodies, a center tap of the far wave power coil is connected with a positive electrode of the power source through a shunting resistor of an ampere meter and a switch, one end of the far wave power coil is connected with collectors of one set of sonar triodes, the other end of the far wave power coil is connected with collectors of one set of triodes to be connected to the ground, a voltmeter is connected to the input end of the power source in parallel, and the ampere meter is connected to the shunting resistor in parallel.

Description

technical field [0001] The invention relates to a far-wave audio sonic device, in particular to a far-wave audio sonic device for carp trapping, and belongs to the technical field of sound wave 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 winter (e...

Problems solved by technology

[0003] At present, when people catch carp in large rivers, lakes or large areas of water, they generally use pull nets. Using pull nets to catch carp on a wider water surface is labor-intensive, and it is very inconvenient to take fish. The caught fish are easy to be injured or leaked. 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
