Description
Technical field
The utility model belongs to tunnel ventilation technical field, particularly a kind of highway tunnel ventilation structure.
Background technology
Air conditions good in traffic tunnel is the necessary condition of traffic safety, and ventilation is in order to the concentration of the pernicious gas in tunnel or pollutant is reduced, and ensures safety and the comfortableness of running car.
The common draft type of existing tunnel has following several:
Natural ventilation: so-called natural ventilation refers to piston action by the automobile of process in tunnel and natural wind action, pernicious gas and flue dust is got rid of in tunnel.Adopt Natural Ventilation Mode to be limited to the size of vehicle flowrate in tunnel, and the air-flow that the unstability of natural wind and complexity can affect in tunnel greatly exchange.
Longitudinal Ventilation: so-called Longitudinal Ventilation introduces fresh air, the mode of the air that decontaminated by another hole from a hole.This mode, air pollution degree is linearly increased to Way out by entrance, and entrance pollution concentration is minimum, surveys pollution concentration large in outlet.Meeting fire situation can cause outlet hole place concentration high, smoke evacuation inconvenience.The ventilator power ratio that existing Longitudinal Ventilation adopts is comparatively large, and cost is higher and noise pollution serious, economic not environmental protection.
Ventilation installation of the prior art can not change the opening and closing of each ventilation installation at any time according to weather and other special circumstances, easily can cause the wasting of resources and the low problem of drafting efficiency.
Summary of the invention
The utility model provides a kind of and can ventilate for highway tunnel, changes the opening and closing of each ventilation installation according to weather and special circumstances at any time simultaneously, also has a kind of highway tunnel ventilation structure of the amount of smoke of early warning system at any time in monitoring channel.
For solving the problem, the scheme that the utility model adopts is as follows:
A kind of highway tunnel ventilation structure, comprise tunnel inner wall and ground, described tunnel inner wall is provided with several air-out passage, it is characterized in that: described air-out passage is provided with several air exhausting device, and air exhausting device is connected with air-out passage by tube connector, and tube connector is provided with smoke alarm, tube connector is arranged with cover body, be provided with base plate bottom cover body, base plate be provided with several air vents, in cover body, be provided with air exhauster; Ground is provided with rhone, rhone is provided with several outfall, described tunnel inner wall distance Ban meter position, ground is provided with water level alarm.
Further, described air-out passage end is provided with ventilation controller.
Further, described base plate one end is provided with the locking device that restriction base plate moves downward.
Further, described air exhauster is provided with several blade.
Further, described air-out passage is provided with is no less than five air exhausting devices.
Further, described air-out passage is provided with six air exhausting devices.
Further, described air-out passage cross section is square.
Further, described air-out passage cross section is square.
Compared with prior art, the utility model has the advantage of: can ventilating, can discharge fume when fire occurs can early warning control maximized exhaust smoke level simultaneously, and being unlikely to waterflooding when there is large rainfall has good draining and early warning system.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As shown in Figure 1-2, a kind of highway tunnel ventilation structure, comprise tunnel inner wall 1 and ground 4, described tunnel inner wall 1 is provided with several air-out passage 2, it is characterized in that: described air-out passage 2 is provided with several air exhausting device 3, air exhausting device 3 is connected with air-out passage 2 by tube connector 16, tube connector 16 is provided with smoke alarm 9, tube connector 16 is arranged with cover body 12, base plate 13 is provided with bottom cover body 12, base plate 13 is provided with several air vents 15, in cover body 12, is provided with air exhauster 10; Ground 4 is provided with rhone 6, rhone 6 is provided with several outfall 5, described tunnel inner wall 1 is provided with water level alarm 7 apart from Ban meter position, ground.
Further, described air-out passage 2 end is provided with ventilation controller 8.
Further, described base plate 13 one end is provided with the locking device 14 that restriction base plate moves downward.
Further, described air exhauster 10 is provided with several blade 11.
Further, described air-out passage 2 is provided with is no less than five air exhausting devices 3.
Further, described air-out passage 2 is provided with six air exhausting devices 3.
Further, described air-out passage 2 cross section is square.
Further, described air-out passage 2 cross section is square.
At ordinary times air-out passage 2 is only opened consistent two air exhausting devices 3, when smoke alarm 9 detects a large amount of smog, open ventilation controller 8, all the other all air exhausting devices 3 are all opened, open locking device to make base plate 13 depart from cover body 12 a large amount of smog can directly be discharged by air-out passage 2, increases smoke exhaust efficiency simultaneously.When setting is no less than five air exhausting devices 3, smoke exhaust efficiency is the highest.Also be conducive to smoke evacuation when air-out passage 2 cross section is square simultaneously, during square, smoke exhaust efficiency is the highest.Ground 4 being arranged rhone 6 facilitates ponding to discharge, tunnel inner wall 1 arranges water level alarm 7 simultaneously, when water arrives water level alarm 7, water level alarm 7 touches water can there is alarm, timely notice relevant departments carry out rescuing and dredge vehicle, avoid causing unnecessary loss and casualties.
A kind of highway tunnel ventilation structure described in the utility model has and can ventilate, and changes the opening and closing of each ventilation installation at any time according to weather and special circumstances simultaneously, also has the feature of the amount of smoke of early warning system at any time in monitoring channel.
