Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises radiating circuit module, emission transducing head, receives transducing head, receiving circuit module, control circuit module and external connection display apparatus, the output terminal of described radiating circuit module is connected with the input end of described emission transducing head, be connected by ultrasonic wireless between described emission transducing head and the described reception transducing head, the output terminal of described reception transducing head is connected with the input end of described receiving circuit module, and described receiving circuit module is connected with described external connection display apparatus by described control circuit module.
As shown in Figure 2, described control circuit module comprises triode BG, slide rheostat W and diode D, the emitter of triode BG is connected with the electrode input end of described control circuit module, the base stage of triode BG and collector are in parallel with slide rheostat W, the positive pole of diode D is connected with the base stage of triode BG, and the negative pole of diode D is connected with the negative input of described control circuit module.
As shown in Figure 2, described control circuit module also comprises the first capacitor C 1, the second capacitor C 2 and resistance R, the first capacitor C 1 is in parallel with the both positive and negative polarity input end of described control circuit module, the second capacitor C 2 and described control circuit module the both positive and negative polarity output terminal in parallel, the two ends of resistance R are base stage and the collector of connecting triode BG respectively.
In conjunction with Fig. 1 and Fig. 2, in the utility model course of work, the electric signal that is produced by the radiating circuit module becomes ultrasonic signal by the emission transducing head, constantly towards periphery radiation in the medium, when liquid not yet will be launched transducing head and receive the transducing head submergence, medium between them is air, and the signal that receives the transducing head reception is not enough to promote the work of control circuit module after amplifying.In case when liquid-immersed emission transducing head and reception transducing head, receive signal and greatly strengthen, work through promoting the control circuit module after amplifying.
As shown in Figure 2, the inductance connecting three point type that is formed by triode BG, it produces the sinusoidal wave oscillator signal about 113KH Z, through delivering to base stage after the resistance R current limliting and emitter directly carries out half-wave rectification, then the collector at triode BG obtains the half-wave amplifying signal, becomes the smooth direct current signal by the first capacitor C 1 and 2 filtering of the second capacitor C and goes to promote triode BG work.After receiving signal, provide enough bias currents by diode D to triode BG, can change the sensitivity of reception by resistance R and adjusting slide rheostat W.
In order to prevent transmitting and receiving signal by electrical short and acoustic short circuit, must and receive transducing head to the emission transducing head and carry out encapsulation process.The lower needs of situation that use at normal temperature are coated with lek to emission transducing head and reception transducing head and cable pigtail and receive glue, be noted that especially, in the gluing process, should guarantee to make the surface of emission and the glue on the receiving plane that are coated in transducing head not to produce bubble.After the whole dryings of coating, put into water and soaked one hour,, more than 2M Ω, can use with the insulation resistance between 500V megger measurement transducer outgoing cable two wires and a polar curve and the water.
