AI Technical Summary
Technical Problem
Existing wind speed sensors are susceptible to dust intrusion in dusty environments, which can cause bearing jamming or failure, resulting in unstable operation and affecting measurement accuracy and lifespan.
Method used
A labyrinth sealing assembly, including a labyrinth ring and a labyrinth seat, is used to form a tortuous labyrinth channel, which prolongs the path of sand and dust intrusion and consumes airflow energy, preventing sand and dust from entering the bearing area.
Benefits of technology
This significantly improves the reliability and lifespan of the sensor in dusty environments, ensures clean bearing operation, and enhances the accuracy of wind speed measurement and the stability of the sensor.

Abstract
The utility model discloses a dustproof wind speed sensor belongs to wind speed measurement technical field. Including the wind cup, the rotating shaft, the base and set up between the wind cup and the base's labyrinth seal component, the labyrinth seal component is by with the wind cup synchronous rotation's labyrinth ring and with the fixed base's labyrinth seat constitutes, and the zigzag labyrinth passage with multiple gyration parts is formed between two, when the airflow carries the dust and attempts to invade, the labyrinth passage passes through the extension invasion path and multiple change airflow direction, effectively consumes the airflow kinetic energy, promotes the dust particle settlement to block its into the bearing area on the basis of keeping traditional wind speed sensor appearance, through the innovative labyrinth seal structure has promoted the dustproof capacity significantly, especially suitable for desert, construction site and so on dust environment, effectively solved the bearing easy to jam, the sensor short life technical problem.
