Problems solved by technology

For normal or large-level winds, the anemometer can measure the wind speed normally, and the anemometer will not be damaged by the wind; however, when encountering strong winds or particularly large-level winds, the parabolic cone on the anemometer The empty cup will be rotated by the wind at a very high speed, and the gust of wind or a particularly large level of wind will blow the speedometer continuously, which will easily damage the parabolic cone empty cup and the auxiliary bracket mechanism, thus affecting the use of the entire anemometer

specific Embodiment approach

[0068] Specific embodiments: When the parabolic cone empty cup 41 is not blown by the wind, the drive sleeve 40 and the centrifugal wheel 9 will not rotate, and then the output shaft 2 will not rotate; in this state, the centrifugal friction in each actuator 8 The arc surface of the block 18 is in frictional contact with the outer surface of the output shaft 2, and there is pressure between the centrifugal friction block 18 and the output shaft 2. For each actuator 8: the end of the ejector rod 23 away from the square piston 22 is in contact with the centrifugal piston block 15 is in contact with each other, the first spring 24 is in a stretched state, the sides of the centrifugal piston block 15 away from the first spring 24 are respectively in contact with the large inclination slopes 31 of the two limit blocks 25 and the centrifugal piston block 15 is opposite to the two limit blocks. The pressure at 25 is zero. When the centrifugal friction block 18 is in friction fit with...

Abstract

The invention belongs to the technical field of anemometers, and particularly relates to an anemometer. The anemometer comprises a clutch mechanism, an output shaft, a cylinder shell, an arc-shaped swing plate, a parabolic cone hollow cup and a measuring module, wherein the clutch mechanism can guarantee that the friction force between a centrifugal friction block and the output shaft is kept unchanged basically when a centrifugal wheel does not exceed a set critical value, so that a centrifugal friction block keeps the position of the whole clutch mechanism unchanged for a long time by the centrifugal friction block and the output shaft through the friction force. After the anemometer meets fierce wind or high-grade wind, the parabolic cone hollow cup can automatically retract into the cylinder shell, and the situation that the parabolic cone hollow cup on the anemometer is blown out by the fierce wind or especially high-grade wind is avoided; meanwhile, the mechanical damage caused by a driving sleeve and the centrifugal mechanism during ultra-high-speed rotation is avoided, and the effect of protecting the anemometer is achieved. The anemometer is simple in structure and has a good use effect.

Description

technical field [0001] The invention belongs to the technical field of anemometers, in particular to an anemometer. Background technique [0002] For the anemometer among the measuring instruments of the meteorological monitoring station, the anemometer is a mandatory verification measuring instrument stipulated by the Metrology Law of my country. The anemometer is an instrument for measuring air velocity, and the most commonly used one in meteorological stations is the wind cup anemometer, which consists of three parabolic cone empty cups fixed on the bracket at 120° to each other to form the sensing part, and the parabolic cone empty cups are all forward One direction; the entire induction part is installed on a vertical rotating shaft, and under the action of wind force, the parabolic cone hollow cup rotates around the shaft at a speed proportional to the wind speed. For normal or large-level winds, the anemometer can measure the wind speed normally, and the anemometer w...
