Wind direction and wind speed monitoring device

Abstract

The invention discloses a wind direction and wind speed monitoring device, and belongs to the field of wind direction and wind speed measuring instruments. A first rotating shaft is connected with a cover plate and a box body through bearings and penetrates through a through hole of the box body to be connected with a wind cup; a second rotating shaft is respectively connected with the box body, an upper turntable and a lower turntable through bearings, and the upper turntable is provided with a plurality of light emitters and light receivers which are circumferentially and uniformly distributed for wind direction monitoring; a plurality of rotating wheels are uniformly distributed on the circumference of the rotating piece and are connected with the first rotating shaft through flat keys; a sliding sheet of a force transmission block is matched with the cover plate and a sliding groove of the box body; the tail end of the force transmission block and a spring are connected with the box body, and the tail end of the force transmission block is fixed to the center of a simply supported beam; an optical fiber processed with a light leakage area is adhered to the simply supported beam through flexible glue; and two ends of the optical fiber are respectively connected with a light source and a photoelectric triode. According to the invention, remote wind direction and wind speed monitoring is realized, the structure is simple, and wind direction and wind speed monitoring can be realized in strong electromagnetic interference and flammable and combustible environments.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a wind direction and wind speed monitoring device. Background technique [0002] Most wind direction anemometers on the market measure wind speed through rotating parts such as wind cups and propellers, and measure wind direction through wind vanes. However, most of these anemometers measure wind direction and speed directly or indirectly through the correspondence between electrical signals, wind direction and wind speed, and cannot be applied to wind direction and speed monitoring in specific environments such as inflammable and explosive environments. Optical fiber sensing technology has the advantages of high sensitivity, good linearity, anti-magnetic and explosion-proof, and strong adaptability to the environment. Therefore, the use of optical fiber sensing technology for wind direction and speed monitoring can overcome the shortcomings of current wind direction and anemometers. C...
