In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1-3:

the utility model provides an overhead wisdom street lamp, includes lamp pole 1, built-in fitting 2 and water conservancy diversion subassembly 4, the lamp pole is fixed with built-in fitting 2, and built-in fitting 2 bottom side is connected with leading guide rod 3; the water conservancy diversion subassembly 4 includes a plurality of concentric setting's horizontal grounding ring 43, horizontal grounding ring 43 center sets up electrically conductive cover 41, is radial connection a plurality of conducting strips 42 between electrically conductive cover 41 and the horizontal grounding ring 43, all sets up conducting block 44 in the crossing position of horizontal grounding ring 43 and conducting strip 42, and conducting block 44 downside is connected with a plurality of perpendicular ground inserts 45, and electrically conductive cover 41 installs the downside that is located built-in fitting 2 on main guide arm 3.

When electric leakage and lightning stroke occur, current is guided by a lightning rod at the top end of the lamp pole, is downwards transmitted through the lamp pole, and enters the bottom surface through the main guide rod 3 by the embedded part 2, so that good grounding performance is ensured, damage to electric appliances is avoided, main current is downwards and vertically introduced into the deep ground by the main guide rod 3, step voltage peaks around the lamp pole are restrained, and step voltage restraining effects are effectively improved.
