Anemometer for meteorological monitoring

Abstract

The invention belongs to the technical field of anemometers, in particular to an anemometer for meteorological monitoring, which comprises a cylinder shell, a swinging mechanism, a wind measuring mechanism, a hydraulic mechanism and a measuring module, wherein the greater the rotating speed of a parabolic cone empty cup blown by the wind is, the shorter the distance of the parabolic cone empty cupstretching out of the cylinder shell is, further the shorter the distance of the first rotating shaft stretching out of the cylinder shell is; thus, the vibration amplitude generated when the first rotating shaft is blown by the wind is smaller, so as to protect the first rotating shaft indirectly. When the parabolic cone empty cup is subjected to special large-scale wind blowing, the parabolic cone empty cup can completely stretch into the cylinder shell, so as to achieve the purpose of protecting the parabolic cone empty cup; in addition, when the wind outside is small, the parabolic cone empty cup can move and restore out of the cylinder shell again to continue to measure the wind speed.

Description

technical field [0001] The invention belongs to the technical field of anemometers, in particular to an anemometer for meteorological monitoring. Background technique [0002] At present, 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 our 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 th...

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 blown by the wind and rotate at a very high speed, and the gust of wind or a particularly large level of wind will continue to blow the anemometer, which will easily damage the parabolic cone empty cup and the auxiliary bracket mechanism, thus affecting the use of the entire anemometer
