In this way, when the covering column (204c) moves along with the covering top (204a), it is embedded into the downward movement groove (201a) to realize the limitation of the installation position of the infrared detector (201c).

9. The device for infrared detection of carbon brushes according to claim 8, characterized in that: The locking member (205) comprises a left limiting column (205a) fixedly connected to the covering top (204a) at a position corresponding to the left limiting groove (203b), and a right limiting column (205b) fixedly connected to the covering top (204a) at a position corresponding to the right limiting groove (203c). The left limiting column (205a) and the right limiting column (205b) are engaged with the positions of the clamping plate (202c) and the upper blocking block (203a) as the covering top (204a) moves, thereby further improving the limitation on the installation of the infrared detector (201c).

10. A method for infrared detection of carbon brushes, characterized in that: The device for infrared detection of carbon brushes according to any one of claims 1 to 9 comprises the following steps: First, by installing the detector, data collection is performed to accurately monitor the extent and location of carbon brush use; Secondly, by analyzing the data, detailed reports of trend analysis and location distribution maps are generated to assist maintenance decision-making; Then, it supports remote access via the network to achieve real-time data viewing and management, improving convenience and efficiency; Finally, abnormal warnings are issued based on preset thresholds, with fault detection and diagnosis functions, providing timely reminders and maintenance information.
