Problems solved by technology

However, due to the presence of four wind rods 21-24 in this wind speed sensor, they are easily affected by each other when the wind blows, and there is a problem of inconsistency in the wind, which leads to the reduction of measurement accuracy or the inability to measure accurately at all.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0019] As shown in the figure: a strain-type wind direction sensor, including a support base 1, a strain beam 2, a wind rod 3, and a strain sensor 4; the support base 1 is provided with a strain beam 2, and the wind rod 3 is arranged on the support At the center of the base 1 , the strain beam 2 is arranged radially along the support base 1 with the wind pole 3 as the center, and the strain sensor 4 is arranged on the strain beam 2 .

[0020] The supporting base 1 is circular or cylindrical, and the strain beams 2 can be made of materials such as metal or engineering plastics. The number of the strain beams 2 is at least 4, and one end of all the strain beams 2 is connected at the center of the top of the supporting base 1. The other ends of all the strain beams 2 are connected to the side of the support base 1 and are evenly distributed in the center of the circle. ...

Abstract

The invention relates to a strain-type wind direction sensor, which belongs to the technical field of atmospheric sounding. The strain-type wind direction sensor comprises a supporting base, strain beams, a wind pole, and strain sensors, wherein the strain beams are arranged on the supporting base; the wind pole is arranged in the center of the supporting base; the strain beams are radially arranged along the supporting base with the wind pole as the center; and the strain sensors are arranged on the strain beams. According to the strain-type wind direction sensor provided by the invention, one wind pole is adopted, mutual interference between wind poles and inconsistency of wind effects can be effectively prevented, the strain sensor and the wind pole are separated, and wind effects on the strain sensor are reduced.

Description

technical field [0001] The invention relates to a strain-type wind direction sensor, which belongs to the technical field of atmospheric detection. Background technique [0002] Wind speed and wind direction are important meteorological parameters, which are of great significance to atmospheric scientific research, daily life, industrial and agricultural production, and transportation. Therefore, wind speed and wind direction measuring instruments have been widely used in many occasions. There are many kinds of wind speed and wind direction measurement principles and corresponding measuring instruments, among which the most widely used is the rotating anemometer, which is composed of a wind cup anemometer and a wind vane. The wind cup anemometer consists of three or four hemispherical or parabolic empty cups, which are evenly distributed to form a rotating structure. Under the action of wind force, its rotational speed is proportional to the wind speed, and the wind speed ...
