When the lightning arrester is used, the lightning arrester body 5 is used for wiring, the lightning arrester has a main lightning protection grounding function, the mounting component 2 is used for fixed mounting, and the adjusting component 4 is used for adjusting the mounting height of the lightning arrester body 5 and ensuring the stability after height adjustment.
When the height of the arrester body 5 is adjusted by using the adjusting assembly 4, the crank 403 is rotated, the transmission shaft 401 is driven by the crank 403 to drive the bevel gear set 404 to move, the hollow sleeve 402 is rotated by the transmission of the bevel gear set 404 and the change of the transmission direction, and the hollow sleeve 402 drives the lifting screw 405 engaged with the inner thread of the hollow sleeve 402 to move along the central axis of the hollow sleeve 402.
The movement of the lifting screw 405 causes the height of the arrester body 5 connected through the bottom plate 406 to be changed, thereby changing the installation height of the arrester body 5.
The backup pad 408 is used for maintaining the stability of arrester body 5 after the height-adjusting, after the altitude mixture control is accomplished, the bracing piece 408 all is located the draw-in groove 409 that corresponds, and all offsets with the lateral wall of the draw-in groove 409 that corresponds, the backup pad 409 through a plurality of directions and the effort that corresponds the counterbalance between the draw-in groove 409, a oppression for offsetting that trend is rocked to the lifting screw 405 to the arrester body 5 and cause, avoid lifting screw 405 to damage in the oppression, lead to the trouble of whole device and the trouble of lightning grounding function.
After adjusting the arrester body 5 to a certain height through the lifting screw 405, the support rod 408 is located in the corresponding clamping groove 409, a certain distance is left between the side walls of the support rod 408 and the corresponding clamping groove 409 at the moment, and the operating crank 403 is rotated reversely at the moment, so that the support plate 408 and the side wall of the corresponding clamping groove 409 are tightly abutted.
