Description
Technical field
A kind of blower fan is the utility model is related to, in particular it is related to a kind of abutment wall formula blower fan.
Background technology
Ventilation blower is by the mechanical energy of input, improves gas pressure and supplies gas side by side the machinery of body, it is a kind of driven
Fluid machinery.Pressure at expulsion is less than 1.5 × 10 pas.Ventilation blower is widely used in factory, mine, tunnel, cooling tower, vehicle, ship
With the ventilation, dust discharge and cooling of building, the ventilation of boiler and industrial furnace and air inducing, the apparatus of air conditioning and household electrical appliance are set
Cooling and ventilation in standby, the drying of cereal and are selected and recommended, inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc..Embedded wall at present
The wall type fan of installation, catch net or shutter mostly are filled in outdoor side, when running into larger wind and rain, it is impossible to prevent well
The situation that only rainwater and winged insect get at blower fan.
Publication No. CN204783767U patent document discloses a kind of rain-proof insect prevention abutment wall blower fan, which describe including
There are casing, motor, impeller, certainly vertical shutter and rain cover；The casing has an air channel, and the inner of casing is provided with connection
The air inlet of the inner in air channel, the motor and impeller be may be contained within air channel, and impeller is installed on the output shaft of motor, should
The outer end of casing is mounted on from vertical shutter and rain cover, being covered outside rain cover from the shutter that hangs down, rain cover has air outlet,
Air outlet connects the outer end in air channel, and the air outlet tilts down, and the inner side of air outlet is covered with fly net.By being equipped with
Rain cover, hang down shutter and fly net certainly, effectively can prevent outdoor rain from getting in using rain cover and from the shutter that hangs down, profit
It can prevent that insects are from the outside into the room with fly net, it is achieved thereby that the purpose of rainwater-proof and anti-insects.But the technical side
Case circulates, what wind can only be voluntarily will hang down certainly there is the place of deficiency to the wind for forming impeller in casing and rain cover
Blade on shutter is blown open, therefore certain energy need to be lost when blowing blade open for wind, therefore causes energy to a certain extent
The waste in source；On the other hand, when stuck situation be present from the blade on the shutter that hangs down, blade is caused to damage when wind is to blade
It is bad, or wind can not effectively circulate.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of abutment wall formula blower fan, ensures the air-flow that impeller is formed
Effectively circulated in casing and rain cover.
To achieve the above object, the utility model provides following technical scheme：
A kind of abutment wall formula blower fan, including casing and shutter, shutter in the casing, the shutter include framework and
More blades, more rotating shafts are provided with the framework, the blade described in multi-disc is connected in rotating shaft, it is characterized in that：Also wrap
Drawstring and cylinder are included, the upside of the blade described in every is connected with drawstring, the lower end of the drawstring and the piston rod of cylinder
Connection, the cylinder are installed on the lower surface of casing.
Pass through above-mentioned technical proposal, during the piston rod retracted downward of cylinder, drawstring is pulled to move down, drawstring linkage is each
The upside of piece blade moves down so that the downside per a piece of blade up tilts, and shutter is opened, on shutter
Blade open after, the air-flow that impeller is formed just effectively can circulate in casing and rain cover, while also ensure that blade
Normal service life；When needing to close shutter, the piston rod of drive cylinder pushes up, and drawstring is in relaxed state,
In this case, the downside of blade can naturally droop in the presence of deadweight, shutter is closed, plays the effect of rain-proof insect prevention.
Preferably, the upside of the blade described in every offers connector, and the drawstring passes through connector and blade
Upside connects.
Pass through above-mentioned technical proposal, the connected mode can facilitate the connection between drawstring and blade, and upon connection,
Drawstring can realize upper and lower displacement, and can also realize the displacement of left and right simultaneously, therefore can be sent out with blade in rotation process
Raw left and right displacement is adapted.
Preferably, it is equipped with thicken strip on the downside of the blade described in every.
Pass through above-mentioned technical proposal, the thicken strip can increase the weight on the downside of blade so that shape of the drawstring in no pulling force
Under state, the downside of blade can be naturally drooped under self-acting power, and shutter is closed.
Preferably, the thicken strip is magnet, per a piece of described equal iron plate of blade.
Pass through above-mentioned technical proposal, when being in hang per a piece of blade, magnet can be next with blade where it
Blade mutually adsorbs, and to ensure the sealing between blade, plays more efficiently rain-proof and vermins-proof effect.
