Description
Technical field
The present invention relates to the fields of pipe gallery intelligently realizing explosion-proof and venting of dust explosion cover board and real-time detection.
Background technique
Underground blood vessels of the city integrated piping lane as city are the lifelines of the goods and materials such as water, electricity, natural gas conveying.It is comprehensive
The dangerous source of piping lane itself easily becomes the attack of terrorism and wartime enemy launches air raids strike under current complicated international situation
Emphasis.Feeding port (inspection shaft) is the important component of pipe gallery oral area, enters corridor being usually mainly used for pipeline.Due to
The size of feeding port (inspection shaft) is larger, and the shock wave that wartime explosion generates is easily accessible pipe gallery, thus in piping lane
Lifeline engineering generates destruction.Therefore, feeding port (inspection shaft) needs emphasis to consider as the weak link in people's air defense design.
Secondly, on June 1st, 2014, Kaohsiung City, Taiwan Province street occurs fuel gas and leaks, and causes multiple huge explosion, in explosion accident,
Due to the destruction of shock wave, most of well lid is caused directly to be blown up without enough venting of dust explosion apertures again in the underground space.Work as punching
When hitting wave source outside piping lane, cover board should resist shock wave effectively to guarantee the steady of underground pipe gallery inside lifeline engineering
It is fixed.It explodes inside piping lane, shock wave should be discharged in time, prevent structure from bigger destruction occurs.Therefore, it is necessary to
The requirement that people's air defense is taken into account for current city integrated piping lane feeding port (inspection shaft) designs a kind of novel, practical intelligent chemoprevention
Quick-fried and venting of dust explosion cover board.
Summary of the invention
People's air defense Air Defense Requirement is taken into account in order to meet while feeding port in pipe gallery (inspection shaft) meets normal use, together
When consider disaster prevention (fire and explosion etc.) in piping lane, the present invention, which devises, a kind of takes into account people's air defense design for pipe gallery
Feeding port (inspection shaft) intelligently realizing explosion-proof and venting of dust explosion cover board, on cover plate main body, ventilation, explosion-proof and venting of dust explosion orifice module can be real
Existing cover board respectively corresponds the ventilation requirement in daily piping lane use, fights in ventilation, explosion-proof and three kinds of functional modes of venting of dust explosion conversion
When piping lane take precautions against natural calamities in protection requirements (anti-external impact wave) and piping lane inside disaster three kinds of situations of row pressure demand (venting of dust explosion mouth),
And record is realized by cover board monitoring control module and is calculated, and analyzes explosion-proof and venting of dust explosion cover board state.Cover board monitoring control mould
Block includes pressure monitoring module, angular transducer etc., it can be determined that the working conditions such as cover board, aperture, pair of automatic online
