Embodiment 1

[0025] An accidental explosion-proof manhole cover includes a well circle 1 and a cover body 2, and the cover body 2 is embedded in the well circle 1. A through hole 3 is arranged on the cover body 2, and the through hole 3 may be a rainwater hole or a cover flip hole. The bottom of the well ring 1 or the cover body 2 is provided with a sealing device 4, the inside of the sealing device 4 is provided with a cavity 5, the through hole 3 communicates with the cavity 5, and a plurality of water outlet holes are provided on the side wall of the sealing device 4 6. The sealing device provided can effectively prevent the through hole from being directly connected with the sewage pipe, so that cigarette butts and firecrackers fall into the cavity of the sealing device instead of directly falling into the sewage pipe, thereby effectively preventing cigarette butts and firecrackers from falling into the sewage pipe to cause damage. Explosion; water outlet holes are set on the side wal...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to an accidental explosion-proof manhole cover. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. When the biogas produced by the sewage in the sewage pipe or the sewage well is mixed with the oxygen in the pipe or well to a certain ratio, a violent explosion will occur when it encounters an open flame. Every year in our country, there are several accidents where children throw firecrackers into the sewage pipes through the sewage manhole cover, causing injuries. The rainwater hole and cover hole of the old-fashioned manhole cover are directly connected to the pipe or the sewage well. The open flame cigarette butts and the firecrackers played by children can easily fall into the sewage pipe or the sewage well, causing an explosion. At present, there is no well cover that can solve the above...
