Manhole cover preventing accidental explosions
The invention discloses a manhole cover preventing accidental explosions, and relates to the technical field of manhole covers. The manhole cover preventing the accidental explosions comprises a well ring and a cover body. A through hole is formed in the cover body, a sealing device is arranged at the bottom of the well ring or the cover body, a cavity is arranged in the sealing device, the through hole is communicated with the cavity, and water outlet holes are formed in the side wall of the sealing device. Compared with the prior art, the manhole cover has the advantages that the sealing device is arranged on the lower portion of the well ring or the cover body, so that cigarette butts and fireworks fall into the cavity of the sealing device rather than directly fall in pollution discharge pipes, and accordingly the explosions caused due to the fact that the cigarette butts and the fireworks fall into the pollution discharge pipes are effectively avoided. Besides, the water outlet holes are formed in the side wall of the sealing device, and normal use of the manhole cover is not affected.
