A magnetic wind speed and direction sensor

Abstract

The application relates to a magnetic wind speed and direction sensor, which includes an antimagnetic housing and a bottom fixing part. A plurality of equal-strength cantilever beams are evenly distributed on the outer circumference of the antimagnetic housing, and horizontally arranged on the inner side wall of the antimagnetic housing. Equal-strength cantilever beams, the ends of the equal-strength cantilever beams are equipped with magnetic ligands, and fiber gratings are pasted on the surface, universal balls are installed in the middle of the bottom fixing part, and there is a channel in the middle of the universal balls for rigid wires. Pass through, the lower end of the rigid wire is connected to the magnetic ball, and there are multiple long shafts on the side wall of the antimagnetic housing. The ends of the long shafts are respectively connected with pulleys to form a pulley block for the rigid wire to bypass. The rigid wire passes through the magnetic ball in turn. The ball, the universal ball and multiple pulleys are finally connected to the lever. The end of the lever is also provided with a magnetic ligand. Ligand relative settings. The magnetic wind speed and direction sensor of the application has high precision, high sensitivity, little damage, long service life and simple and convenient operation.

Description

technical field [0001] The application relates to a magnetic wind speed and direction sensor, which is suitable for the technical field of wind direction detection. Background technique [0002] Due to the long-term use of the engineering structure, it is constantly affected by factors such as wind impact, rain and snow erosion, resulting in dynamic softening of the foundation of the engineering structure and erosion and aging of materials, resulting in the attenuation of the engineering structural components and the overall resistance, affecting the structure. safety and durability. Therefore, long-term monitoring of the wind load of structures is of great importance to grasp the performance evolution of engineering structures, evaluate the working state of structures, carry out targeted and reasonable maintenance, avoid various safety accidents, ensure the safety of structures and improve the service life.

Problems solved by technology

Through the review of domestic and foreign materials, it is found that the research on the fiber grating wind speed and direction sensor is not perfect so far. Generally, the cantilever beam where the fiber grating is located is collided, and the change of the fiber reflection wavelength caused by the expansion is measured. Measuring strain

The collision will cause the cantilever beam to generate a lot of friction, which is easy to damage, and the accuracy is not high

The existing fiber grating wind speed and direction sensors are difficult to be applied to the safety monitoring of engineering structures due to their shortcomings such as low accuracy and sensitivity, short life, and large volume.
