Background technology
In China a lot of fish culture specialist is arranged at present, they are in the results time or when checking the healthy fish state, still adopt the catching method of more original clumsiness, such as adopting electric shock, agricultural chemicals, explosive, sonic attraction, fishnet seizure etc. down, these modes cause fish death easily, cause water body pollution in wide area, the death together of big fish small fish, can not accomplish not put very much and keep the ecological balance for a short time.
Summary of the invention
The embodiment of the invention provides a kind of ultrasonic transducer, uses this ultrasonic transducer can make that fishing is more convenient and fish is not caused death, and is beneficial to catch to put little greatly and realize the ecological balance.
The ultrasonic transducer that the embodiment of the invention provides comprises:
Input filter, direct current to input carries out current limliting filtering, output output galvanic current at described input filter, the input of o controller is connected with the output of described input filter, by controlling described galvanic transmission, control hyperacoustic output, the input of concussion pusher is connected with the output of described o controller, the output of concussion pusher is connected with the input of inverter circuit, to described inverter circuit input concussion electric current, described inverter circuit changes and exports the frequency of described concussion electric current, the input of described transducing output transformer is connected with the output of described inverter circuit, output ultrasonic wave, wherein said frequency of ultrasonic is in the 0-20HZ scope.
Optionally, described o controller passes through the control to relay, thereby controls hyperacoustic output.
Optionally, use chip TC4069 to realize described o controller.
Optionally, use chip GC3524 to realize described o controller.
By on see, use the technical scheme of the embodiment of the invention, the ultrasonic transducer that is suitable for present embodiment is fished, because ultrasonic wave has stronger penetration capacity, can be in water body energy lasting, propagate at a distance, when it runs into the fish body in communication process, and all there is trickle rhythmical pulsation in fish body each several part, this pulsation is generally 2-16HZ, with these intrinsic pulsation of topic just in time in the frequency of ultrasonic scope, in case suitably the ultrasonic wave of power acts on the fish body, can cause strong resonance, this resonance acts on the nerve of fish, body, make fish sensation expiratory dyspnea, thereby emerge, the user just can be according to own required fishing for like this, feasible fishing is more convenient, and fish is not caused death, be beneficial to catch and put little greatly and the realization ecological balance.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper qualification of the present invention, in the accompanying drawings:
The structure of ultrasonic transducer schematic diagram that Fig. 1 provides for the embodiment of the invention 1;
Fig. 2 realizes schematic diagram for a kind of circuit of the ultrasonic transducer that the embodiment of the invention 2 provides.
The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment 1:
The structure of ultrasonic transducer schematic diagram that Fig. 1 provides for present embodiment, as shown in the figure, this ultrasonic transducer comprises: input filter 101, o controller 102, concussion pusher 103, inverter circuit 104, transducing output transformer 105.
Input filter 101 carries out current limliting filtering to the direct current of importing, at its output output galvanic current.Input filter 101 inserts the direct current of 12V, makes electric current through input filter 101.Because supply network is a three-phase sine-wave, the frequency of per second 50HZ, but in actual use, his sine wave all can distort, and consumer requires than under the condition with higher electrical network, this electric current spreads all over the application that is fit to consumer.
Input filter 101 is by the harmonic wave in the capacitance-resistance absorption plant filtering electric current, and wherein, resistance refers to inductance, and it mainly plays current limliting; Hold referring to electric capacity, its effect is filtering, and both add up and just constitute the capacitance-resistance absorption plant, and both combine the effect that can also play power factor compensation.
The input of o controller 102 is connected with the output of input filter 101, by the galvanic transmission that control is imported, controls hyperacoustic output.
The input of concussion pusher 103 is connected with the output of o controller 102, the output of concussion pusher 103 is connected with the input of inverter circuit 104, to inverter circuit 104 input concussion electric currents, the frequency that inverter circuit 104 changes and electric current is shaken in output.
The effect of inverter 104 is the direct current of input is converted to the alternating current that frequency changes within the specific limits, the operation principle of inverter 104 is, by a concussion chip, perhaps specific circuit, controlling the output of oscillator signal, such as output 50HZ signal, then this signal is amplified, promote FET or IGCT and constantly carry out the switch switching, like this after the direct current input, action through this FET or IGCT, just form certain AC characteristic, the correction through reconditioning circuit just can obtain the sort of sine wave AC on the similar electrical network, in the present embodiment, the frequency range of the interchange of its output is: 0-20HZ.
The input of transducing output transformer 105 is connected with the output of inverter circuit 104, output ultrasonic wave, and wherein said frequency of ultrasonic is in the 0-20HZ scope.
By on see, use the technical scheme of the embodiment of the invention, the ultrasonic transducer that is suitable for present embodiment is fished, because ultrasonic wave has stronger penetration capacity, can be in water body energy lasting, propagate at a distance, when it runs into the fish body in communication process, and all there is trickle rhythmical pulsation in fish body each several part, this pulsation is generally 2-16HZ, with these intrinsic pulsation of topic just in time in the frequency of ultrasonic scope, in case suitably the ultrasonic wave of power acts on the fish body, can cause strong resonance, this resonance acts on the nerve of fish, body, make fish sensation expiratory dyspnea, thereby emerge, the user just can be according to own required fishing for like this, feasible fishing is more convenient, and fish is not caused death, be beneficial to catch and put little greatly and the realization ecological balance.
