Description
Technical field
The utility model belongs to tunnel construction facility technology field more particularly to a kind of tunnel ventilation device.
Background technique
Currently, the prior art commonly used in the trade is such that
Toxic and harmful gas present in tunnel is always the main hazard source in constructing, if construction wrong easily occurs
Serious accident.
Pernicious gas in tunnel engineering typically refers to gas, biogas (methane CH4), carbon dioxide (CO2), hydrogen sulfide
(H2S) and the natural-gas such as radon gas, these pernicious gases are not only harmful to the health of human body, and are all inflammable gas, often
It sprays suddenly, causes catastrophic failure, these pernicious gases frequently occur in the coal measure strata of relative closure construction, it is also possible to
Occur in non-coal seam stratum.
Pernicious gas is mostly to encounter in construction in the tunnel for penetrate coal seam, also has minority to be because being on the verge of coal seam construction, and
Neighbouring geological structure is convenient for the infiltration or transmission of gas.
Tunnel ventilation blower is mainly used for discharge in tunnel construction, when due to explosive charge, the use of internal combustion engine, excavation
Pernicious gas is released in layer, is that good construction environment is provided for tunnel construction, upkeep operation personnel's health ensures just
Often, smooth construction improves working efficiency, ensures the essential condition of construction quality.
Pernicious gas in tunnel is very large for the injury of human body, if do not arranged gas therein
It removes, cleans, it is easy to cause that worker is poisoned or even the risk of Tunnel explosion, existing ventilation device generally use multiple air blast
Machine carries out air draft, and blower noise is too big, in this closed space of tunnel, can generate very big echo, influence constructor
The health of member, and a large amount of dust floatings are be easy to cause in air by air blower, it is not easy to it is cleared up.
In conclusion problem of the existing technology is:
(1) existing tunnel ventilation device noise is too big, in this closed space of tunnel, can generate very big return
Sound influences the health of construction personnel；
(2) air blower can blow afloat the dust in tunnel, cause a large amount of dust floatings in air, it is not easy to carry out clear
Reason.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of tunnel ventilation device.
The utility model is realized in this way a kind of tunnel ventilation device is provided with
Exhaust fan；
It is welded with air outlet on exhaust fan, is provided with suction opening below exhaust fan, suction opening is fixedly connected by connecting hoop
There is air draft pipe, air draft pipe outer cover is equipped with multiple pipeline fixing bolts, and air draft pipe tail end is welded with suction opening in hole；
Blower duct is fixed with by the support bar welded inside air draft pipe, the blowing mouth of blower duct tail end is sheathed on
In hole in suction opening.
Exhaust fan and air blower are mounted on the outside of tunnel by the utility model, so that the noise generated can not be in tunnel
Construction personnel impacts, and blower duct is arranged in air draft pipe, the carry out exhausting that can be independent of each other and blowing, to tunnel
While being sent into fresh air in hole, effectively the pernicious gas in hole can be sucked out, avoid being poisoned in tunnel
Or the phenomenon that explosion；And this device is additionally provided with protective net at the suction opening of bottom end, and can be effectively prevented will be in tunnel
Small article intake line in result in blockage.
Further, there are two pipeline connection buckles for two sides setting up and down for adjacent air draft pipe junction, and junction is connected with close
Seal.
It is even closer that the utility model by pipeline connection buckle fixes adjacent air draft pipe, passes through sealing ring
It can prevent gas leakage.
Further, air draft pipe outer wall offers multiple exhausting holes.
The utility model is aspirated by the air that exhausting hole can will be far from suction opening in hole, convenient for will float in air
Floating dust is cleared up.
Further, protective net has been bolted on the inside of suction opening and exhausting hole in hole.
The utility model can prevent the small article of sucking construction site by protective net, to cause air draft pipe stifled
Plug.
