Wherein: each ultrasonic transmitter-receiver be triangle and transmitting-receiving mouth be inner side inclined side and towards troughs for collecting energy, the indent arc groove that described troughs for collecting energy is is the center of circle with the center of ultrasound wave dash receiver.
Wherein: the below of described ultrasound wave expelling plate is also provided with installation portion, described installation portion is truncated cone shape so that carry out insertion installation, and described installation portion is provided with multiple shrinkage pool.
Wherein: be provided with internal thread in described shrinkage pool to be secured by bolts on the cabin of blower fan.
Wherein: between described ultrasound wave expelling plate and installation portion, be also provided with transition connection portion, described transition connection portion is gradual shrinkage ripple struction.
Wherein: described ultrasound wave expelling plate, ultrasonic transmitter-receiver, transfer tube and ultrasound wave dash receiver are equipped with heating element.
Known by said structure, modified form anemoscope of the present utility model has following effect:
1, structure is simple, and easy to use, structural strength can be guaranteed;
2, anemoscope better transmits maximized absorption and utilization by troughs for collecting energy, the ultrasound wave launched can be concentrated on reflecting plate center by ball-type design, then receiving trap is reflected back by collecting in next set of signals, ultrasonic wavelength-division can be changed so completely and spread the signal loss caused, strengthen signal receiving strength, measuring error is reduced to and minimizes.
Detailed content of the present utility model obtains by explanation described later and institute's accompanying drawing.
