Far wave megalobrama amblycephala trapping acoustic wave device

Abstract

The invention discloses a far wave megalobrama amblycephala trapping acoustic wave device. A far wave transformer is provided with a short wave oscillating coil, a frequency modulation control coil and a sonar power coil. A voice wave capacitor is connected to an output end of the short wave oscillating coil in series, and the short wave oscillating coil has two output ends. The frequency modulation control coil is provided with two symmetrical coil bodies, a center tap of the frequency modulation control coil is jointly connected with emitters of two sets of voice frequency triodes through a resistor and a negative electrode of a power source, the other two ends of the frequency modulation control coil are respectively connected with bases of the voice frequency triodes through diodes and connected with bases of the voice frequency triodes through diodes, the sonar power coil is provided with two symmetrical coil bodies, a center tap of the sonar 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 sonar power coil is connected with collectors of one set of voice frequency triodes, the other end of the sonar power coil is connected with collectors of one set of voice frequency 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 trapping sound wave device, in particular to a far-wave sound wave device for trapping bream, and belongs to the technical field of sound wave sensing electronics. Background technique [0002] At present, when people are fishing in large surface waters, they generally use cast nets. It is not possible to specialize in the catch of bighead bream. It is inefficient to use cast nets in a wide water surface. The caught fish are easily injured or missed. The fish that escape due to injury or missed catch will be frightened, thus affecting the The normal growth of species and the occurrence of various fish diseases, and because of the depth of the water, there are many aquatic plants and rocks at the bottom of the river, it is difficult to use the net, and the efficiency of catching pomfret is low. Contents of the invention [0003] The purpose of the present invention is to provide a convenient and quick trapping effe...
