Background technology
Especially diasonograph and sonicator widespread use is used in the Ultrasonic Detection treatment on clinical medicine.Early stage ultrasonic power measuring device adopts analog element and discrete component, the volume of instrument is big, power consumption is big, control is inconvenient, and adjust repeatedly by the radiant force sedimentation balance method, transducer is not aimed at absorbing target fully, cause power meter all not receive it and transmit, cause data not accurate enough.The error that produces human factor when this measurement mechanism is popped one's head in the acoustic field that sends for high strength simultaneously is bigger, and power deviation is too big, and the distance of ultrasonic probe and pyramid absorbing target is located artificially, and each measuring error is all different.
Summary of the invention
The purpose of this utility model is that the precision that exists at existing sedimentation balance method ultrasonic power measurement is low, be subjected to the big problem of interference from human factor, it is comparatively accurate to design a kind of location, and it is more accurate that the focal zone of ultrasonic transducer is measured, practical ultrasonic power measuring device.
The technical solution of the utility model is:
A kind of ultrasonic power measuring device, it is characterized in that it comprises sound absorbing water tank 1 and the absorbing target 2, force cell 3 and the probe bracket 4 that are installed in the sound absorbing water tank, ultrasonic transducer 5 is installed on the probe bracket 4, absorbing target 2 be positioned at ultrasonic transducer 5 under, absorbing target 2 is installed on the pallet 6, pallet 6 is bearing in force cell 3, force cell 3 is installed on the base 9, the output of force cell 3 links to each other with sensor control circuit, and sensor control circuit is electrically connected with the LCDs 7 and the printer 8 that are positioned at outside the sound absorbing water tank 1.
Described absorbing target 2 is the absorbing target of stainless steel hollow pyramid structure.
Described probe bracket 4 is the scalability probe bracket, and it can be with doing moving up and down with respect to absorbing target 2 by ultrasonic transducer 5.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of ultrasonic power measuring device, it is characterized in that it comprises sound absorbing water tank 1 and the absorbing target 2 that is installed in the sound absorbing water tank, force cell 3 and probe bracket 4, ultrasonic transducer 5 is installed on the probe bracket 4, absorbing target 2 be positioned at ultrasonic transducer 5 under, absorbing target 2 is installed on the pallet 6, pallet 6 is bearing in force cell 3, force cell 3 is installed on the base 9, the output of force cell 3 links to each other with sensor control circuit (as shown in Figure 2), sensor control circuit is electrically connected with the LCDs 7 and the printer 8 that are positioned at outside the sound absorbing water tank 1, as shown in Figure 1.Absorbing target 2 can adopt stainless steel hollow pyramid structure, and measuring accuracy is improved through electroplating to increase reflection potential in the surface.Measurement for the sound power level that adapts to different capacity, probe bracket 4 of the present utility model adopts monolithic processor controlled small-sized electric push rod, be the scalability probe bracket thereby it is become, it can be with doing moving up and down with respect to absorbing target 2 by ultrasonic transducer 5.
The ultrasonic transducer ultrasonic waves transmitted forms radiation pressure on pyramid absorbing target 2.Sound wave reaches on the pallet 6 through film, the change of acoustic pressure causes the variation of pallet 6, this pressure is delivered on the dynamometry quantity sensor 3, force cell 3 is converted to electric signal to pressure, carries out drawing ultrasonic power after the signal Processing through sensor control circuit then, and digital display demonstrates the intensity of acoustic energy, thermal printer real time print power waveform and numerical value (peak power, average power, test duration, peak time etc.).Sensor control circuit can adopt 51 microcontroller C8051F060 at a high speed, carries out signal with operational amplifier LTC-1100 and amplifies.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
