Basic concept and application range of anemometer
Anemometer, as the name suggests, is an instrument for measuring air velocity. There are many types of it, 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 concave surfaces of the empty cups are all in one direction. The whole induction part is installed on a vertical rotating shaft, and under the action of wind force, the wind cup rotates around the shaft at a speed proportional to the wind speed. Another rotary anemometer is the propeller anemometer, which consists of a three-blade or four-blade propeller as the sensing part, which is installed on the front end of a wind vane so that it is always aligned with the direction of the wind. The blades rotate around a horizontal axis at a speed proportional to the wind speed.
The anemometer is an instrument for measuring the speed of the wind. Maybe we ignore the speed of the wind many times because we think that the wind speed has nothing to do with us. In fact, the wind speed is closely related to many industries. Many industries use anemometers. The following Let's look at some examples.
Anemometers were used to measure the table tennis and badminton venues for the 2008 Beijing Olympic Games. Because the venues are equipped with air-conditioning, the original designer wanted to deliver air-conditioning through large vents. It has an impact on table tennis and badminton games. Too much wind will cause the ball to deflect. After some thinking, the designer decided to change the large vent to a small vent, that is, install a small air outlet on each seat, so that It can also achieve the effect of air-conditioning. Although the cost of this idea is relatively high, after the measurement of the anemometer, the venue meets the airflow standard required by the International Olympic Committee.
Anemometers have other applications in the Beijing Olympic Games, such as sailing competitions, rowing competitions, field shooting competitions, etc., all need to use anemometers for measurement. The current anemometer is relatively advanced, in addition to measuring wind speed, it can also measure wind temperature and air volume. There are many industries that need to use anemometers, but people have not realized it. With it, your work may be easier and the quality of work will be higher.
Recommended industries: sea fishing, various fan manufacturing industries, industries that require ventilation and exhaust systems, etc.
