At this time, the L-shaped rotating rod 804 rotates within the slotted frame 803, thereby driving the slotted frame 803 to swing back and forth. Then, the slotted frame 803 drives the connected L-shaped swing rod 802 to swing back and forth, causing the other end of the L-shaped swing rod 802 to slide within the slide groove 801, thereby driving the arc-shaped brush plate 8 to move back and forth, so that the bristles on the arc-shaped brush plate 8 can clean the outer wall of the lightning rod 6.

[0030] Working principle: When a lightning protection device needs to be installed on a pavilion in an ancient building, first, the mounting base 1 is placed on the top of the pavilion, and then multiple eaves positioning plates 301 are placed on the outside of the pavilion eaves. Then, by rotating the threaded rod 302, the threaded rod 302 can drive the eaves clamp frame 304 connected to the hinge seat 303 to move, and the eaves positioning plates 301 are clamped and fixed on the eaves of the pavilion for installation and fixation; Then align the positioning rod 401 at the bottom end of the protective seat 4 with the mounting hole 201 and insert it. At this time, due to the tapered structure of the bottom end of the positioning rod 401, the limiting rod 202 will be pushed open. Then, under the action of the spring 203, the limiting rod 202 will be inserted into the annular groove 402 on the positioning rod 401 to be fixed in position. When the lightning rod 6 is needed, the motor 501 is used to drive the connected mounting frame 5 to rotate so that the opening of the receiving slot 502 on the mounting frame 5 faces upward. During this process, the adjusting wheel 705 engages with the arc-shaped rack 403, thereby driving the transmission rod 704 connected to the adjusting wheel 705 to rotate, so that the transmission rod 704 can drive the worm 703 connected to the universal joint 702 to rotate; Then the worm 703 can drive the worm wheel 603 to rotate, so that the worm wheel 603 drives the connected rotating shaft 602 to rotate, and then the rotating shaft 602 can drive the connected rotating base 601 to rotate, so that the lightning rod 6 on the rotating base 601 is removed from the mounting frame 5 and erected for lightning protection; When the lightning rod 6 is not in use, the mounting frame 5 is driven to rotate in the opposite direction to drive the lightning rod 6 back into the mounting frame 5, and then the storage slot 502 on the mounting frame 5 opens downward, cooperating with the protective seat 4 to protect the lightning rod 6; At the same time, when the mounting frame 5 rotates, under the action of the annular rack 404, the transmission wheel 805 will rotate. At this time, the transmission wheel 805 will drive the connected L-shaped rotating rod 804 to rotate. At this time, the L-shaped rotating rod 804 will rotate in the slotted frame 803, thereby driving the slotted frame 803 to swing back and forth, and then the slotted frame 803 will drive the connected L-shaped swinging rod 802 to swing back and forth, so that the other end of the L-shaped swinging rod 802 slides in the slide groove 801, thereby driving the arc-shaped brush plate 8 to move back and forth, so that the bristles on the arc-shaped brush plate 8 can clean the outer wall of the lightning rod 6, which can effectively remove dirt and dust on the surface of the lightning rod 6, keep the equipment clean, improve the conductive performance, extend the service life and reduce maintenance costs, and also improve the intelligence and automation level of the device, enhance the safety and reliability of the equipment.
