This application provides a sliding sealing mechanism and a compressed air energy storage device. The sliding sealing mechanism includes a first sleeve, a first tube body, and a connector. The first sleeve has a movable hole. The first tube body is sleeved in the movable hole. The first tube body can be connected to or detached from the first sleeve. The first tube body is connected to a sealing element. One end of the connector is inserted into the first sleeve, and the other end of the connector is inserted into the first tube body. When the outer end of the first sleeve is positioned at the external positioning sealing section, the first tube body impacts the connector as the upper tube body moves, until the connector changes from an intact state to a disconnected state. The first tube body can move relative to the first sleeve. The sealing element seals with the first sleeve as the first tube body moves. The connector ensures that the first tube body and the first sleeve are in a stationary state due to their contact. When the connector is in a disconnected state, the first tube body and the first sleeve are sealed, simplifying the structure of the sliding sealing mechanism.

The present invention discloses a line patrol robot and an obstacle crossing method using a winch. The winch is installed in the box of the line patrol robot. The rope of the winch is connected to a load-bearing gripper, and the load-bearing gripper is fixedly installed with a telescopic rod through a connecting piece. When the line patrol robot crosses an obstacle, the load-bearing gripper is placed on the wire, and cooperates with the front walking gripper or the rear walking gripper to ensure the stability of the center of gravity of the line patrol robot when crossing the obstacle. At the same time, when the line patrol robot needs to be removed from the cable, the winch releases the rope, and the line patrol robot can fall by itself, without the need for the staff to climb up the profiling tower or the pole again to remove it, which greatly saves labor costs and operation time. In addition, there are solar panels on the surface of the box, which can provide uninterrupted power supply to the equipment, ensuring the line patrol efficiency of the line patrol robot.
