Megalobrama amblycephala trapping sound generator

Abstract

The invention relates to a megalobrama amblycephala trapping sound generator which comprises a transformer, a capacitor and triodes, wherein an output end of an oscillation coil of the transformer is connected with the capacitor in series, a central shaft head of the oscillation coil of the transformer is connected with a negative electrode of a power supply and emitting electrodes of the triodes, and another two ends of the oscillation coil are respectively connected with base electrodes of a diode and the triodes; a central shaft head of a power coil of the transformer is connected with a positive electrode of the power supply through a shunt resistor of an ampere meter and a switch, one end of the power coil is connected with a collecting electrode of one triode, and the other end is connected with a collecting electrode of another triode and is grounded; an input end of the power supply is connected with a voltmeter in parallel, and the shunt resistor is connected with the ampere meter in parallel. The fish trapping device has the advantages of simple structure, small size and convenient use, and the oscillation wave of the fish trapping device resonates with the sleeping frequency of megalobrama amblycephala so that the megalobrama amblycephala is captured in sleep. The life habit of the megalobrama amblycephala is not influenced, and the lobar intensity of fish trapping is low.

Description

technical field [0001] The invention relates to a sonic fishing device, in particular to a sonic generator for trapping bream. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] At present, when people fish in large rivers, large lakes or large areas of water, they generally use dragnets and cast nets. It is not possible to specialize in catching bighead bream. 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 fish, and it is very inconvenient to catch fish. When using a cast net or a pull net, the fish caught are very It is easy to be injured or missed catch, and the 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; The water is shallow, there are many aquatic plants and rocks at the bottom of the river, it is difficult to use the net, and the...
