The utility model relates to a nameplate recognition device for power equipment. The device comprises a bottom plate, a lead screw is rotatably fixed to the right end face of the bottom plate, a motoris fixed to the top end of the lead screw, the lead screw is connected with an output shaft of the motor, a supporting sliding block is fixed to the lead screw, a camera is fixed to the left inner side of the supporting sliding block, and the motor rotates to drive the lead screw to rotate and further drive the camera to move up and down along the lead screw to adjust the height. A chip, a storage unit and an image sensor are arranged in the camera, and the image sensor is used for collecting nameplate information, transmitting the collected information to the chip for processing and storingthe information. The system has the advantages that nameplate equipment, models, parameters and other information can be automatically collected, operators can conveniently carry out on-site investigation operation, the working efficiency is improved, the checking accuracy is improved, and the situation that internal and external service archive information corresponds to mistakes is avoided. Andthe lifting mechanism can well adapt to collection of nameplates of power equipment at various heights.
