Abstract

The invention relates to an acoustic wave generator for trapping alepidote fish, which belongs to the acoustic wave generators for trapping the alepidote fish. The generator for trapping the fish comprises a transformer, a capacitor and a triode, wherein the output end of an oscillator coil of the transformer is series-connected with the capacitor; a center tap of a control coil of the transformer is connected with a negative electrode of a power supply and an emitter of the triode through a resistor, and the other two ends of the control coil are respectively connected with a base of the triode through a diode; and the center tap of a power coil of the transformer is connected with a positive electrode of the power supply through a shunt resistor of a current meter and a switch, one end of the power coil is connected with a collector of the triode, the other end is connected with the collector of another triode and then grounded, a voltmeter is parallel-connected on the input end of the power supply, and the current meter is parallel-connected on the shunt resistor. The fishing device has simple structure, small volume and convenient use, and the shock waves generate resonance with the frequency of sleep of the alepidote fish, thereby catching the sleeping alepidote fish. The acoustic wave generator does not affect the living habits of the alepidote fish and leads the labor intensity when fishing to be low.

Description

technical field [0001] The invention relates to a sonic fishing device, in particular to a sonic generator for trapping scaleless fish. 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 cannot specialize in catching scaleless fish. 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 easy Injured or missed catches, the escaped fish due to injuries or missed catches will be frightened, thus affecting the normal growth of fish and the occurrence of various fish diseases; , 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 scaleless fish is low. Contents of the invention [0003] The purpose of the present invention is to pr...
