Intelligent weather station wind speed detector

Abstract

The invention relates to the technical field of wind speed detection and discloses an intelligent meteorological station wind speed detector. The detector comprises a shell, wherein a shaft rod is rotatably sleeved with the shell, the top end of the shaft rod penetrates through the top of the shell and extends to the outer side of the shell, a wind cup is fixedly sleeved with the top end of the shaft rod, and a supporting plate is arranged in an inner cavity of the shell; and a pre-rotating device is arranged above the supporting plate, a driving assembly and a damping mechanism which are located below the supporting plate are arranged in an inner cavity of the shell, and a movable magnet is fixedly connected to the bottom of the shaft rod. According to the detector, the shaft lever can also move up and down along with the change of the wind speed by utilizing the action of the rising force of the wind speed on the streamline supporting plate in the vertical direction, and the rotation of the shaft lever can be intermittently hindered through the damping mechanism when the wind speed is reduced; therefore, the rotating speed of the shaft lever is reduced to balance the problem of slow reduction of the rotating speed caused by the rotational inertia of the shaft lever, and the wind speed measurement precision of the wind speed measurement instrument is improved.

Description

technical field [0001] The invention relates to the technical field of wind speed detection, in particular to an intelligent weather station wind speed detector. Background technique [0002] The anemometer is an instrument for measuring the air velocity. There are many types of it, including cup anemometers, ultrasonic anemometers and acoustic anemometers. The wind cup anemometer consists of three conical empty cups fixed on the bracket at 120 degrees to each other to form the sensing part, and the concave surfaces of the empty cups are all in the same direction. The entire induction part is installed on a vertical rotating shaft. Under the action of the wind, the wind cup rotates around the shaft at a speed proportional to the wind speed, and at the same time drives the coaxial multi-tooth cutting disc or magnetic rod to rotate, and the wind cup is obtained through the circuit. The pulse signal proportional to the rotation speed, the pulse signal is converted by the count...
