Drop, this structure solve the problems, such as that rainwater pours into ventilation shaft, still, since the direction at this structural tube road junction is still to be in
Face upward wind face, when head-on wind, which has, flows backward in pipeline, equally causes adverse effect to blower, therefore there is no complete for this structure
It solves the problems, such as.
Utility model content
In order to solve the above technical problems, the utility model provides cap structure outside a kind of new blower intake stack room, not only
It can effectively prevent air port water inlet, moreover it is possible to natural wind be avoided to flow backward.
For achieving the above object, the technological means that the utility model uses is:
Blast cap outside a kind of new blower intake stack room, including the blast pipe connecting with ventilation shaft, blast pipe outer end is equipped with
Umbrella shape shielding cap, shielding cap include inside and outside two layers of baffle, and outer layer baffle is affixed in top and two sides conjunction side with internal layer baffle；Two
There is cavity, cavity bottom is blocked by bottom plate between layer baffle；Blast pipe and internal layer baffle are affixed, and blast pipe nozzle is located at cavity
Interior, internal layer baffle gathers ventilation hole.
The utility model all shelters from the top of wall hole, side, front, and rainwater can not flow into intake stack, into
The upper and lower, left and right of air hose and the positive cap that is all blocked block, and blast pipe air inlet direction is contrary with air hose air draught, in fresh air
When machine not air draught natural wind can not blow-through blast pipe, solve the problems, such as head-on wind flow backward.
Preferably, outer layer baffle and internal layer baffle inner wall are equipped with acoustical cotton layer.Wind can be effectively reduced and disturb making an uproar for generation
Sound.
Preferably, the bottom plate is by outer layer baffle connecting side to the acclivitous setting of internal layer baffle connecting side.
Preferably, bottom plate is equipped with drainage hole, if there is the water of inflow, is flowed out by bottom drain holes.
Preferably, the outer layer baffle center line L and horizontal line are in 45-70 ° of angle, internal layer baffle center line N and level
Line is in 40-65 ° of angle.And preferred 5-15 ° of the angle between two baffles.
The 1/5 of the minimum air inlet pipe diameter of interval H, H, maximum to equal than air inlet should be kept between internal layer baffle, outer layer baffle
Pipe diameter value.
Shielding cap whole height is entered the wind between 1.5-2 times of pipe diameter.
Can interspace≤blast pipe radius in advance between blast cap part and wall.Blast cap part can also be allowed closely to connect with wall
It connects.
Detailed description of the invention
Fig. 1 is the utility model structure chart；
Fig. 2 is the utility model angle of depression figure；
Fig. 3 is line A-A cross-sectional view in l Fig. 2；
Fig. 4 is the utility model installation condition elevation structure figure；
Fig. 5 is that the utility model air inlet moves towards schematic diagram.
In figure: outer layer baffle 1, internal layer baffle 2, blast pipe 3, bottom plate 4, ventilation hole 5.
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing:
New blower ventilation shaft outer end is located at outside wall, is usually open in the piping outside the house port.New blower fortune
Risk in row from outdoor mainly includes two kinds of factors of rainwater and downdraught.Rainwater includes the rainwater to flow downward along exterior wall
With the rainwater being blended in wind.In the indefinite natural environment of wind direction, at pipeline tapping no matter towards it is left, towards it is right or downward all without
Method has avoided head-on wind blow-through completely.
The utility model provide it is a kind of can not only stop rainwater, the structure of blow-through wind can also be blocked, specifically:
Blast cap outside a kind of new fan wind inleting tube Room 3 as shown in Figs 1-4, including the blast pipe 3 being connect with ventilation shaft,
3 outer end of blast pipe is equipped with umbrella shape shielding cap, and shielding cap includes inside and outside two layers of baffle, and outer layer baffle 1 and internal layer baffle 2 are in top
And two sides conjunction side is affixed；There is cavity, cavity bottom is blocked by bottom plate 4 between two layers of baffle；Blast pipe 3 and internal layer baffle 2 are solid
It connects, 3 nozzle of blast pipe is located in cavity, and internal layer baffle 2 gathers ventilation hole 5.
The utility model all shelters from the top of outer wall opening, side, front, and rainwater can not flow into intake stack, this
Structure air inlet direction is contrary with fan induced draught, and natural wind can not be directly blown into the ventilation shaft of blower, be efficiently solved
The problem of head-on wind flows backward.
Preferably, outer layer baffle 1 and 2 inner wall of internal layer baffle are equipped with acoustical cotton layer.Wind can be effectively reduced and disturb generation
Noise.
Preferably, the bottom plate 4 is by 1 connecting side of outer layer baffle to the acclivitous setting of 2 connecting side of internal layer baffle.
Preferably, bottom plate 4 is equipped with drainage hole, if there is the sundries such as the water of inflow that can flow out by bottom drain holes.
1 center line L of outer layer baffle and horizontal line are in 45 ° to 70 ° angles, and 2 center line N of internal layer baffle and horizontal line are in 40 °
To 65 ° of angles.There is 5-15 ° of angle to be more conducive to enter the wind between preferred two baffle.
Should keep interval H between internal layer baffle 2, outer layer baffle 1, the 1/5 of minimum 3 diameter of blast pipe of H, it is maximum to equal than into
3 diameter value of air hose.Shielding cap whole height is between 1.5-2 times of 3 diameter of blast pipe.
The size of above-mentioned each section is adjusted according to the intake of new fan design, and the low then angle of intake increases,
Height reduces, and angle on the contrary reduces, and increases height, increases incoming air area.
Blast pipe 3 can paste sponge or weld the connection sheet of other fixed functions in surface layer according to the actual situation, facilitate fixation.
Interspace≤blast pipe radius in advance between blast cap part and wall, can then allow screening than the region of comparatively dense in rainwater
It is bonded between gear cap and wall, while doing encapsulation process, air inlet is upwardly into cavity, blast pipe below blast cap.
The ventilation hole 5 of internal layer baffle 2 can suitably increase and decrease according to demand, and 5 area summation of ventilation hole should be greater than 3 nozzle of blast pipe
Area.Internal layer baffle aperture size determines that hole shape is arbitrarily selected according to service condition.
