Abstract
The invention relates to the ventilation technology of urban highway tunnels, and discloses an automatic wind-catching ventilation system at the top of an urban highway tunnel, which is suitable for urban highway tunnels with openings at the top. The heat collecting device can collect solar radiation heat and convert the solar radiation heat into kinetic energy for air circulation. The automatic wind catching device can quickly catch the main wind of the incoming flow from any direction. When the incoming wind outside the tunnel sweeps across the device horizontally, the wind catching opening can automatically face the incoming wind direction by utilizing the moment balance principle regardless of the incoming wind direction, and the external air is introduced into the tunnel. The solar heat collecting device and the automatic wind catching device are arranged at intervals, automatic ventilation can be realized in the road tunnel with the top opening, no running power is needed, and the solar heat collecting device and the automatic wind catching device are simple and easy to use and have obvious energy-saving effect.
Description
Technical field
The invention belongs to HVAC and building energy saving field, be specifically related to urban road tunnel top automatic wind-trapping ventilation system, belong to tunnel ventilation technical field.
Background technology
At present, for alleviating growing urban traffic pressure, some cities adopted erection viaduct to construct Urban Rapid-Transport passage in the past.The traffic aisle formed due to viaduct has larger negative effect for civic landscape, Urban conservation, produces larger traffic noise simultaneously, and many cities start selection and build city underground traffic tunnels in recent years.Can predict the continuous growth along with Forecast of Urban Traffic Flow, the exploitation of the underground space will be strengthened greatly, and this kind of tunnel will constantly continue to increase.
Subterranean tunnel air ambient solution not only has influence on the form of structure in tunnel, more mainly determines the height of tunnel day-to-day operation cost to a great extent.Different from ordinary highway tunnel, this kind of city inner tunnel belongs to shallow embedding formula tunnel (tunnel top is apart from ground about 2 ~ 6m) more, but length of tunnel more and more increases, last century the nineties based on 200 ~ 300 meter Guo street short tunnels, present then based on zonal passage, length reaches more than 3000 meters.Traditional ventilation settling mode adopts jet blower mechanical ventilation, but this mode causes tunnel internal noise high, and environment is poor, consumes again a large amount of operation electric power.The air ambient problem actually adopting which kind of mode effectively to solve this kind of tunnel is the significant problem that Urban Underground Space Excavation application needs conscientiously to solve.
Summary of the invention
The object of the invention is for prior art above shortcomings, a kind of urban road tunnel top automatic wind-trapping ventilation system is provided.Native system can realize automatic ventilation in open-topped highway tunnel, does not need to run electric power, and put things right once and for all, energy-saving effect is self-evident.
Technical scheme of the present invention is:
This is caught wind ventilation system and is applicable to open-topped urban road tunnel, and this system comprises the air chimney of tunnel top, heat collector and automatic wind catcher.Heat collector can collect solar radiation heat, and is translated into the kinetic energy of air circulation.Automatic wind catcher can capture rapidly the incoming flow prevailing wind from any direction.When tunnel outer incoming flow wind levels skims over this device, no matter incoming flow wind direction how, utilizes principle of moment balance, catch air port and all can automatically meet to incoming flow wind direction, outside air is introduced tunnel internal.Solar energy heat collector and automatic wind catcher interval are arranged, and can realize automatic ventilation in open-topped highway tunnel.
Feature of the present invention and further improvement are:
Heat collector and automatic wind catcher are placed in the top of highway tunnel.
Heat collector utilizes hot pressing function to be formed in tunnel and pulls out wind effect.
Automatic wind catcher utilizes Action of Wind pressure that tunnel upper air is introduced tunnel internal, forms air inlet effect.
Heat collector and automatic wind catcher interval use simultaneously, make in tunnel, form multiple natural circulation ventilation effect.
Beneficial effect of the present invention:
System of the present invention can realize automatic ventilation in open-topped highway tunnel, does not need to run electric power, and put things right once and for all, energy-saving effect is self-evident.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of urban road tunnel top automatic wind-trapping ventilation system, comprises heat collector and automatic wind catcher, and heat collector and automatic wind catcher interval are placed in the top of highway tunnel.
Heat collector comprises transparent blast cap 5 and solar energy heating vertical shaft 6, and solar radiation can shine directly into thermal-arrest vertical shaft 6 through transparent blast cap, posts the thermal-arrest material of black inside solar energy heating vertical shaft, collects solar radiant heat for colleges and universities.The heat collected in thermal-arrest vertical shaft can be converted into hot pressing, and air is formed and pulls out wind effect under the effect of hot pressing.
Automatic wind catcher comprises tumbler 2, air intake 3 and wind deflector 4.When incoming flow wind levels skims over this device, no matter incoming flow wind direction how, and incoming flow wind can produce certain rotating torque on wind deflector, and air intake is met to incoming flow wind direction.Utilize Action of Wind pressure that tunnel upper air is introduced tunnel internal, form air inlet effect.
Heat collector and automatic wind catcher are arranged at tunnel top interval, and the air inlet effect pulling out wind effect and automatic wind catcher formation of heat collector formation complements each other, and makes in tunnel, form multiple natural circulation ventilation effect
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
