Anemometer capable of protecting parabolic cone empty cup

Abstract

The invention belongs to the technical field of anemometers, and particularly relates to an anemometer capable of protecting a parabolic cone empty cup. The anemometer comprises a base, a rectangularshell, a position-limit mechanism, a trigger mechanism, an actuating mechanism, and a measuring module. When the wind speed of the outside is larger, the distance from the rotating shaft to the rectangular shell is shorter, the amplitude of the vibration generated when the rotating shaft is blown by the wind is smaller, and the rotating shaft is protected indirectly. When the parabolic cone emptycup is subjected to a particularly large grade of wind blowing, the parabolic cone empty cup can completely enter the rectangular shell, so that the purpose of protecting the parabolic cone empty cupis achieved; in addition, when the outside wind is small, the parabolic cone empty cup can be moved again from the rectangular shell to continue measuring the wind speed. The design of the four position-limit mechanisms can ensure that when the wind blows the position-limit mechanism in a pulsating manner, at least one of the position-limit plates in the position-limit mechanism has a position-limit relationship with the position-limit ring, so that the position-limit ring disc can be continuously limited by the corresponding position-limit plate, and the parabolic cone empty cup can be continuously maintained in the rectangular shell.

Description

technical field [0001] The invention belongs to the technical field of anemometers, in particular to an anemometer capable of protecting parabolic cone empty cups. Background technique [0002] The anemometer is an instrument for measuring air velocity, and the most commonly used one is the wind cup anemometer, which is composed 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 in one direction; The whole 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 will not be damaged by the wind; however, when encountering strong winds or particularly large-level winds, the parabolic cone empty cup rotation speed Super fast, so the parabolic cone e...

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 empty cup rotation speed Super fast, so the parabolic cone empty cup that rotates at super fast speed for a long time is easy to be blown out, thus affecting the use of the entire anemometer
