Description
Technical field
The utility model relates to municipal piping lane Design of ventilation fields, specially the distributing natural ventilating structure of piping lane, special
It Shi Yongyu not the biggish electric compartment piping lane of excess heat.
Background technique
The most important draft type of piping lane is ventilating shaft formula force ventilation at present, the force ventilation of ventilating shaft formula generally with nature into
Based on wind, mechanical exhaust.For electric compartment, the heat dissipation capacity of cable is very big, and the air quantity requirement for eliminating waste heat is also very big.It adopts
With ventilating shaft formula force ventilation, concentrated into, air draft point, the selection of the ventilation equipment model such as blower, air-valve can very big and single-point into
The exhaust effect of wind mode is bad.Due to the heat dissipation capacity of cable be it is lasting, ventilation equipment need to be in long-time opening state
State can greatly reduce the service life of ventilation equipment, bring lasting, huge noise, and cause huge energy consumption.
It is computed, air quantity needed for eliminating cable heat dissipation capacity in electric compartment is very big, is difficult to meet by single-point ventilation.
Summary of the invention
In order to overcome the above technical defects and insufficient, the utility model provides a kind of distributing gravity-flow ventilation knot of piping lane
Structure solves existing piping lane and divulges information the technical problem that unsmooth, noise is big, energy consumption is big.
The following technical solution is employed for the utility model:
The distributing natural ventilating structure of piping lane, including long and narrow piping lane, the piping lane include subsurface native interlayer and
Piping lane cabin under the soil interlayer, which is characterized in that it is perpendicular that multiple air inlets are arranged in the piping lane on the outside of one side wall along its length
Well, the air-intake shaft air inlet setting on the ground, the bottom surface of the air-intake shaft is concordant with piping lane bilge face, it is described into
Piping lane cabin described in open communication is arranged in wind shaft wall bottom, setting air inlet Electric air valve in the opening；The piping lane into
Multiple exhaust air shafts for leading to ground are arranged in the inside sidewalls of wind vertical shaft opposite side, and the exhaust air shaft bottom surface is the cabin in piping lane cabin
Top, exhaust air shaft bottom surface setting cabin push up ventilation opening and are connected to piping lane cabin, and the electronic wind of air draft is arranged in cabin top ventilation opening bottom
Valve；The air-intake shaft and exhaust air shaft are staggered；
Piping lane cabin both ends are exhaust air shaft, and fire-fighting is arranged on the cabin top ventilation opening in one exhaust air shaft
Electronic smoke exhaust fire damper is arranged in blower, bottom.
In the interlayer, the air-intake shaft and exhaust air shaft periphery are soil.
Metallic grid is covered on the well head of the air-intake shaft and exhaust air shaft.
The air-intake shaft and exhaust air shaft cross sectional shape are rectangle or circle.
The utility model piping lane distributing first outstanding feature of natural ventilating structure is exactly to disperse.The structure shape of piping lane
Formula be it is long and narrow, the lasting heat dissipation capacity of cable is difficult effectively to exclude especially in electric compartment.Distributing gravity-flow ventilation changes
In a traditional ventilation subregion, an air inlet point is set, the draft type of an air draft point improves multiple into, row to have
The structure of wind point, and firefighting fan and smoke exhaust fire damper are mounted in piping lane, the use discharged fume after fire is not influenced.
The utility model piping lane distributing second outstanding feature of natural ventilating structure is exactly nature.Piping lane distributing is certainly
So hot pressing function that ventilation is formed using piping lane inside and outside temperature difference, relative low temperature atmospheric density out of my cabin is big, settles downwards, from pipe
Corridor lower part air port enters, and the high temperature air density in piping lane is small, can rise, and naturally drains from the air port on top, in this way, in piping lane
Waste heat just by with the form of " draught " discharge.Due to reducing the frequency of use of ventilation equipment, energy consumption can be substantially reduced.
The utility model energy conservation, noise abatement, reduce equipment size, extend equipment life, do not influence the premise discharged fume after calamity
Under, the exclusion of huge waste heat in piping lane can be effectively realized.
For synthesis, the beneficial effects of the utility model are as follows:
1) hot pressing function is utilized, the waste heat in piping lane is excluded by gravity-flow ventilation；
2) quantity and size for reducing the ventilation equipment such as blower, air-valve, reduce type selecting number；
3) by the arrangement of multiple ventilation points, effectively solve the problems, such as that electric compartment heat extraction is difficult；
4) ventilation equipment continuous service bring noise is eliminated；
5) number of run for reducing ventilation equipment, extends the ventilation equipment service life, reduces energy consumption；
6) waste heat not only can be effectively excluded, but also can effectively be discharged fume after fire.
