This method can eliminate the need for the staff to support the device when the device is cleaning and wiping, reducing the labor intensity of the staff and avoiding the cleaning operation of the device due to sore hands At the same time, the use of medium drive can also ensure that the clamping force of the two clamping plates on the SF6 meter is consistent, thereby improving the clamping effect. At the same time, when the clamping plate moves, under the action of the connecting rod, the guide plate will follow The clamping plate moves synchronously, and the dust is guided by the top slope of the guide plate, and the dust will automatically enter the collection frame. It directly enters into the collection frame. When the operation is not being cleaned, the guide plate will cover the collection frame to prevent the dust in the collection frame from dumping when the device is not moving.

4) The present invention sets the handheld structure and telescopic structure, and when the SF6 meter is at a low place, the L-shaped connecting rod moving device can be directly used, and the length of the telescopic structure is adjusted according to the height of the SF6 meter, and the telescopic rod is pulled. After the telescopic rod is moved to a suitable position, use the fixed rod and the circular hole to fix the height of the telescopic rod and the handle rod. For example, when the SF6 meter is at a high place, use the telescopic structure to hold it. At the same time, the arc block is more sufficient for the telescopic structure Adjust the angle to facilitate the SF6 meter to better enter the inside of the frame, which is convenient for the early fixing work. Rotate the telescopic rod. The angle of the structure is fixed to avoid a large range of shaking of the frame when the device is moved.
