Supersonic transducer

Abstract

The invention discloses an ultrasonic transducer which relates to the fishing device field. The ultrasonic transducer comprises an input filter, an output controller, an oscillation thruster, an inverting circuit and a transduction output transformer. The input filter limits current and filters wave of the input direct currents. Stable direct currents are input at the output end of the input filter. The input end of the output controller is connected with the output end of the input filter. The output of input filter is controlled by controlling the transfer of the direct currents so as to control the output of the ultrasonic transducer. The input end of the oscillation thruster is connected with the output end of the output controller and the output end is connected with the input end of the inverting circuit. The oscillation current is input to the inverting circuit. The inverting circuit changes and outputs the frequency of the oscillation current, and the frequency is within a range of 0-20Hz. The water electrically connected to the output end of the transduction output transformer outputs the alternating current with the voltage transformation. By using the ultrasonic transducer, the fishing can be more convenient and the fish is not killed, which is beneficial to the principle of ''catching the big fish, releasing the small fish'', thus realizing ecological equilibrium.

Description

technical field [0001] The invention relates to the field of fishing equipment, in particular to an ultrasonic transducer used for fishing. Background technique [0002] At present, there are many professional fish farming households in our country. When they are harvesting or checking the health status of fish, they still use relatively primitive and clumsy fishing methods, such as electric shocks, pesticides, explosives, sound lures, fishing nets, etc. These methods easily lead to the death of fish, causing large-scale pollution of water bodies, and the death of large and small fish together. Contents of the invention [0003] An embodiment of the present invention provides an ultrasonic transducer. Using the device can make fishing more convenient and prevent fish from dying, which is beneficial to catch big and let go of small to achieve ecological balance. [0004] The ultrasonic transducer provided by the embodiment of the present invention includes: an input filter...

[0002] At present, there are many professional fish farming households in our country. When they are harvesting or checking the health status of fish, they still use relatively primitive and clumsy fishing methods, such as electric shocks, pesticides, explosives, sound lures, fishing nets, etc. These methods easily lead to the death of fish, causing large-scale pollution of the water body, and the death of both large and small fish. It is impossible to maintain ecological balance without letting go of large and small fish.
