The input of said concussion pusher is connected with the output of said o controller, and output is connected with the input of inverter circuit, be used for to said inverter circuit input concussion electric current,
The concussion current conversion that said inverter circuit is used for the input of said concussion pusher is the alternating current that frequency changes in preset range,, the frequency of wherein said alternating current in the 0-20HZ scope,
The input of said output transformer is connected with the output of said inverter circuit, is used for the alternating current after the water body output transformation that is electrically connected with said ultrasonic transducer, output ultrasonic wave.
Optional, said o controller passes through the control to relay, thereby controls hyperacoustic output.
Optional, said o controller is the TC4069 chip.
Optional, said o controller is the GC3524 chip.
Therefore, the technical scheme of the application 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, and this pulsation is generally 2-16HZ, with the topic these intrinsic pulsation 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 nerve, the body of fish; 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, and is beneficial to catch and puts 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 sketch map that Fig. 1 provides for the embodiment of the invention 1;
A kind of circuit of the ultrasonic transducer that Fig. 2 provides for the embodiment of the invention 2 is realized sketch map.
The specific embodiment
To combine accompanying drawing and specific embodiment to specify the present invention below, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as to qualification of the present invention.
Embodiment 1:
The structure of ultrasonic transducer sketch map 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, 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 through 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; Through controlling the galvanic transmission of being imported; Thereby the output of this ultrasonic transducer is controlled in the output of controlling this input filter 101, promptly is controlled at the output of the sound wave in the water.
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 circuit 104 is that the concussion current conversion with 103 inputs of concussion pusher is the alternating current that frequency changes within the specific limits, and the operation principle of inverter circuit 4 is, through a concussion chip; Perhaps specific circuit is being controlled 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 output transformer 105 is connected with the output of inverter circuit 104, the alternating current after the water body output transformation that is electrically connected with the output of said output transformer, and the frequency of the alternating current of output is in the 0-20HZ scope.
Therefore, the technical scheme of the application embodiment of the invention, the ultrasonic transducer that is suitable for present embodiment is fished; Because the alternating current of output transformer output is propagated in the water body that is electrically connected with this ultrasonic transducer (when promptly utilizing this ultrasonic transducer to carry out " electric fish ", probe being put in the waters of desire " electric fish ") and produced sound wave effect (frequency is in the 0-20HZ scope), this sound 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; The intrinsic pulsation of these of fish body just in time in the frequency range of this sound wave, in case suitably this sound wave of power acts on the fish body, can cause strong resonance; This resonance acts on nerve, the body of fish; 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, and is beneficial to catch and puts little greatly and the realization ecological balance.
Embodiment 2:
Fig. 2 realizes sketch map for a kind of circuit of the ultrasonic transducer that present embodiment provides; Like diagram; In a single day can be not limited to use chip GC3524 to realize said o controller, o controller 102 be through the control to relay, thereby the output of this ultrasonic transducer is controlled in the output of control input filter; Thereby the output of control underwater acoustic wave can use chip TC4069 to realize o controller.
More than the technical scheme that the embodiment of the invention provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
