The invention relates to the field of well lids, in particular to a drainage anti-explosion well lid. The drainage anti-explosion well lid comprises a top cover, wherein an annular groove is formed in the top cover, water inlets are formed in the top cover in an annular array mode, the lower end face of the top cover is fixedly connected with four water inlet pipes evenly distributed below the annular groove, an anti-explosion plate is arranged below the top cover, a bottom plate is arranged below the anti-explosion plate, a first through hole is formed in the center of the anti-explosion plate, a center shaft is rotationally arranged between the top cover and the anti-explosion plate through the first through hole, a rotary blade is fixedly connected to the center shaft, a first limiting ring is arranged at the contact position of the upper end of the center shaft and the top cover, the limiting ring is fixedly connected with the top cover, a second limiting ring is arranged at the contact position of the lower end of the center shaft and the bottom plate, a torsional spring is arranged between the rotary blade and the anti-explosion plate around the center shaft for connection, the water inflow of the well lid is increased in heavy rain to prevent rainwater deposition on a road, and when explosion occurs in the well lid, explosion is limited in one area, and water spraying is conducted to prevent reburning.
本发明涉及井盖领域，具体是一种排水防爆井盖，包括顶盖，所述顶盖开设有环形槽，所述顶盖上环形阵列设有进水口，所述顶盖下端面固定连接均匀分布在所述环形槽下的四根进水管，所述顶盖下方设有防爆板，所述防爆板下方设有底板，所述防爆板中心设有第一通孔，所述顶盖与防爆板之间通过所述第一通孔转动设有中心轴，所述中心轴上固定连接有旋页，所述中心轴上端与顶盖接触处设有第一限位环，所述限位环与顶盖固定连接，所述中心轴下端与底板接触处设有第二限位环，所述旋页与所述防爆板间围绕中心轴设有扭簧连接，实现了在下大雨时增大井盖的进水量防止道路上雨水淤积，井盖内爆炸时，将爆炸限制在一个区域内并进行喷水防止复燃。
