Abstract

PURPOSE:To obtain a stable anemometer enabled to measure the high speed change or the fine change of air speed by fitting a piezo-electric body to a wind receiving part to constitute a piezo-electric vibrator and measuring the resonance frequency to find out the air speed. CONSTITUTION:The piezo-electric body 4 is fitted to the inside of the wind receiving plate 3 arranged on the front of a shelter hood 2 fitted to a supporting rod 1. The wind receiving plate 3 and the piezo-electric body 4 constitute the piezo-electric vibrator, and when wind pressure is generated on the wind receiving plate 3, the force corresponding to the wind pressure is applied to the piezo- electric body 4, so that the resonance frequency is changed. Thus, the high speed change or fine change of air speed can be stably measured by measuring the resonance frequency.

には十分でない。On the wind speed side, there are those that can measure wind speed but not wind direction (pitot tubes), and those that have mechanically moving parts that cannot detect subtle changes in wind speed (Dynes self-recording anemometer, wind cup type). , windmill type), and in hot wire anemometers and ultrasonic anemometers, wind speed is calculated from the time from when heat and ultrasonic waves are emitted from the transmitter to when they are received at the receiver. Therefore, it cannot be said that wind speed is measured in real time, and this is not sufficient to detect subtle wind speeds.

そこで本発明は微小な風速の変化、高速で変化する風速

ようとするものであり、以下本発明の一実施例について
図面を参照して説明する。Therefore, the present invention aims to provide a stable anemometer without mechanically moving parts that can measure minute changes in wind speed and wind speed that changes at high speed. explain.

る。５ａ、　５ｂは出力取出用リード線である。As shown in FIGS. 1 and 2, a windproof hood 2 is attached to the support rod 1. Several wind receiving plates 3 are provided on the front surface of the windproof hood 2, and a piezoelectric body 4 is attached to the inner surface of the wind receiving plates 3. 5a and 5b are output lead wires.

より、風速の測定ができる。The wind receiving plate 3 and the piezoelectric body 4 form a piezoelectric vibrator, and when the wind receiving plate 3 is directed toward the direction of the wind to be measured, wind pressure is generated on the wind receiving plate 3, and the force in response to this wind pressure is transmitted to the piezoelectric body. 4 and the resonant frequency changes. By measuring this resonance frequency, wind speed can be measured.
