The invention discloses an anti-explosion inspection well cover which comprises a base and a seat; an upper cover plate is fixedly installed at the upper end of the base; a gearbox is fixedly installed at the lower end of the base; and a plurality of exhaust cavities and drainage cavities are formed between the upper cover plate and the base, so that gas and solid at the upper end and the lower end of the inspection well cover can be completely separated on the premise that a drainage function is not affected, combustible gas below the inspection well cover cannot overflow to the ground, firecrackers, cigarette ends and other fire sources on a well can only fall into the drainage cavities, and the drainage cavities can extinguish the fire sources through accumulated water. When accidental explosion of underground gas occurs, arc-shaped buffer blocks can pull the inspection well cover to prevent the inspection well cover from flying out under the action of explosion airflow, and a pressure relief device can discharge residual airflow to protect a inspection well cover body.
本发明公开了一种防爆窨井盖，包括底座、基座，所述底座上端固定安装有上盖板，所述底座下端固定安装有齿轮箱，所述上盖板与所述底座之间含有若干个排气腔与排水腔，能够实现在不影响排水功能的前提下将窨井盖上下端的气体与固体完全分离，窨井盖下方的可燃气体不会溢出到地面上，井上的鞭炮、烟头等火源只可能落入排水腔，排水腔能够利用积水熄灭火源，如果井下气体发生意外爆炸时，弧形缓冲块能够拉住井盖，防止其在爆炸气流的作用下飞出，泄压装置能够将剩余的气流排出，保护窨井盖本体。
