Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, specifically to a vibration monitoring sensor for power equipment that is resistant to electromagnetic interference. Background Technology
[0002] A sensor is a detection device that can sense the measured information and transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording and control. In power equipment, sensors are often used to detect the operating status of the equipment to ensure stable operation.
[0003] For example, the Chinese patent with announcement number CN218298317U, entitled "(A Condition Monitoring Sensor for Power Equipment)," includes: a mounting frame, a sensor body movably mounted on the inner surface of the mounting frame, a shock-absorbing block movably connected to the bottom of the mounting frame, and a connection hole fixedly connected to the outer surface of the sensor body. A clamping plate is provided inside the mounting frame. This invention utilizes the cooperation of a shock-absorbing block and a second spring. The shock-absorbing block transmits the electromagnetic vibration of the power equipment to the spring, pushing the slide rod to move within the slide rail. Simultaneously, it pushes the second slider and the buffer block. Through the buffering and energy dissipation of the first and second buffer pads, the amplitude is effectively eliminated, thereby improving the monitoring accuracy of the sensor body. This solves the problem that electromagnetic vibrations generated during the operation of power equipment transmit the vibration force to the monitoring sensor, leading to inaccurate sensor data, and achieves the effect of improving the sensor's monitoring accuracy.
[0004] However, the environment in which existing power equipment is located is usually subject to complex and strong electromagnetic interference, which places extremely high demands on the performance of vibration monitoring sensors. In such a strong electromagnetic environment, vibration monitoring sensors are easily affected by interference signals, resulting in inaccurate and unstable monitoring data, and in severe cases, even failure to work properly. Therefore, it does not meet the existing requirements. In response, we propose a vibration monitoring sensor for power equipment that is resistant to electromagnetic interference.
