Description

Technical Field

[0001] The utility model relates to the technical field of wind generator production, in particular to a limit sensing structure of a wind generator. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind wheel, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. A limit sensor is a sensor used to detect the position of an object. Its basic principle is to detect the position of an object through electrical signals or the movement changes of mechanical parts. The limit sensor can be used to detect the movement of the wind turbine blades. According to different principles, the limit sensor can be divided into contact and non-contact types. The principle of the contact limit sensor is to detect its position by contacting the object. It has a simple structure and low cost, but is easily affected by factors such as the contact area, material and shape of the object. The non-contact limit sensor uses principles such as photoelectric, magnetoelectric or ultrasonic. It can detect the position without contacting the object. It has high accuracy and long service life. The limit sensor is widely used in automated production lines, machinery, tools and robots to detect information such as the position, movement and state of the object. For example, limit sensors are used on machine tools to detect the completion of part processing; limit sensors are used on production lines to detect whether assembly parts are in place and control automated operations; limit sensors are used in robots to detect whether the robot arm has reached the specified position, etc. The main difference between limit sensors and other sensors lies in their application scenarios and control methods. Limit sensors are mainly used in the detection of object position, movement and status, while temperature sensors, pressure sensors, etc. are mainly used to detect different parameters. In terms of control methods, limit sensors are mainly used to control the movement of machinery or robots, while other sensors are used to control the changes in various parameters.

The limit sensing structure of the wind turbine adopts a contactless sensing method to sense the steering angle of the cabin of the wind turbine, avoids mechanical wear, and effectively improves the service life of the limit sensing structure.
