Abstract
The utility model discloses a kind of roof natural ventilation, belong to aeration technology field, including the skeleton of circular arc, be arranged on the end plate at skeleton both ends, be enclosed in the peripheral backplate of skeleton side and installed in intraskeletal weather shield；The top surface of skeleton is provided with protection network；The top of weather shield is provided with least two groups and is used for the flow distribution plates that are shunted and be arranged symmetrically to rainwater, and the bottom of weather shield and flow distribution plate is equipped with tank；Skeleton is provided with movable valve at the throat positioned at ventilator.Roof natural ventilation of the present utility model has that ventilation effect is good, while has good rain and snow and wind sheltering performance, and any size, the natural wind in direction are all without the exhaust effect for influenceing roof ventilator.Roof ventilator can also be clapped arrangement more, may be arranged at the ridge of double slope surface with single arrangement, be also disposed on Sloping roof and arranged along slope.Strong adaptability.It can be widely applied to all kinds of power house ventilations of the departments such as electric power, metallurgy, chemical industry, oil, machinery.
Description
Technical field
Aeration technology field is the utility model is related to, specifically, is related to a kind of roof natural ventilation.
Background technology
The blast that roof natural ventilation is the hot pressing that is formed using indoor/outdoor temperature-difference and wind-force is formed changes to realize
Gas, often there is infiltration in natural ventilator of the prior art.
Notification number discloses a kind of large workshop that is applied to for CN200986285Y patent document needs roof outwards to lead to
A kind of roof natural ventilation of wind, the device are mainly made up of deflector, flashing board, peripheral skeleton and column.Wherein, it is peripheral
The end " A " of skeleton is not intersected directly with column, and leaves space.Because the tie point of column and circular arc skeleton is not in circle
The end of arc skeleton, so flashing plate can be entered in ventilator with whole, rainwater can flow out along flashing plate completely divulges information
Device, can essence solve the hidden danger of ventilator storm seepage in use.
The utility model is disadvantageous in that when amount of rainfall is larger, or even rainstorm weather occurs, single simple layer rain-proof
Plate is easy to be destroyed because of the impact by rainwater.When rainfall is small, rainwater is easy to back in the bottom of flashing board
The phenomenon oozed, flow to the inwall of flashing board along wooden partition and then down drip, do not have the effect of waterproof thus.In addition, by
Rubbish, fallen leaves or birds in the open by design of ventilating opening, external environment condition be easy to be fallen on flashing board by ventilating opening or
Within doors.
Utility model content
The purpose of this utility model effectively can avoid heavy rain from rushing weather shield to provide a kind of roof natural ventilation
Hit, moreover it is possible to prevent rainwater from bleeding back, meanwhile, also prevent extraneous rubbish fallen leaves from being flown within doors or being fallen on weather shield by ventilating opening.
To achieve these goals, roof natural ventilation provided by the utility model includes the skeleton of circular arc, set
End plate at skeleton both ends, it is enclosed in the peripheral backplate of skeleton side and installed in intraskeletal weather shield；The top surface of skeleton is set
There is protection network；The top of weather shield is provided with least two groups flow distribution plates for being used to shunt rainwater and be arranged symmetrically, weather shield
Tank is equipped with the bottom of flow distribution plate；Skeleton is provided with movable valve at the throat positioned at ventilator.
In above-mentioned technical proposal, by setting flow distribution plate to shunt rainwater above weather shield, when there is heavy rain day
During gas, rainwater, which is shunted, can effectively prevent impact failure of the rainwater to weather shield.Protected by being set at the top of skeleton
Net, the rubbish fallen leaves or birds that can prevent the external world are fallen on indoor or weather shield.Meanwhile set in the bottom of weather shield and flow distribution plate
Set sink, the bottom of weather shield and flow distribution plate is stretched into tank, the dew at rainwater or night is along weather shield and flow distribution plate stream
Enter in tank, then discharged by tank, so can prevent a small amount of water from occurring bleeding back phenomenon in the bottom of weather shield.Movable valve is set
With to reach the purpose of any regulation, valve when opening from guide functions, ensure that ventilation effect is good, closure is tight during closing
It is close, it is ensured that heating system presses design conditions normal operation, if factory building water capacity is higher, throat's valve and peripheral backplate can be adopted
Insulation is taken, with antifrost.
Specific scheme is provided with a cross bar for the top of skeleton, and movable valve includes being symmetrical arranged two fans along its movable axis,
Lead provided with the drawstring being wound on cross bar at the edge of valve movable end.
Preferable scheme is that cross bar is provided with pulley, and drawstring is drawn or put by manual control around pulley.
Another preferable scheme is that cross bar drives rotation to control the drawing of drawstring or put by motor.
Compared with prior art, the beneficial effects of the utility model are：
Roof natural ventilation of the present utility model has that ventilation effect is good, while has good rain and snow and wind sheltering
Can, any size, the natural wind in direction eliminate all without the exhaust effect for influenceing roof ventilator and separately set deep bead.Roof
Ventilator can also be clapped arrangement more, may be arranged at the ridge of double slope surface with single arrangement, be also disposed on Sloping roof and
Arranged along slope.Strong adaptability.It can be widely applied to all kinds of power house ventilations of the departments such as electric power, metallurgy, chemical industry, oil, machinery.
