Description
Technical field
Fire service inventory field is the utility model is related to, is concretely a kind of firefighting fan.
Background technology
Firefighting fan had both referred to continuously to run under 300 DEG C of hot conditions more than 60 minutes and had connected under 100 DEG C of temperature conditionss
It is continuous 20 it is small when/industrial fan that time does not damage.When fire occurs for building, firefighting fan, which is opened, send air into building,
Dense smoke and other pernicious gases for endangering personal security are exported, in order to ensure exhaust efficiency, the body of wind turbine often compared with
Greatly, strong noise can be produced in use.
The noise source of wind turbine mainly has the following aspects：Induction and exhaust noises and air-flow flow through the air force of body generation
Property noise；The rigidity such as slave body Surface Radiation Noise and pipeline is transaudient；Impact, the machinery for rubbing and producing when pressing members are run
Noise；The noise that the air-flow of pressuring machine air inlet/outlet pipeline hits, radiated from body and pipe surface etc.；Cooled down by motor
Electromagnetic noise caused by the pulsation of magnetic field between the pneumatic noise of fan, rotor, and the bearing machinery that rotation produces at a high speed are made an uproar
Sound.
Existing denoising device is arranged on wind turbine vane or on motor more, although noise reduction is excellent, production and peace
It is higher to dress up this, is unfavorable for promoting the use of.
Therefore need one kind simple in structure, using muffling device and peculiar defeated wind passage, the air-flow being adjusted into wind turbine,
Be allowed to steadily so as to reduce because and air-flow flow through body generation air power noise a kind of firefighting fan.
Utility model content
The utility model is arranged on wind turbine vane or on motor, although noise reduction is excellent more for existing denoising device
It is good, but production and installation cost are higher, the problem of being unfavorable for promoting the use of, there is provided a kind of firefighting fan.

The effect of body flow velocity, noise when being greatly reduced into wind turbine vane.
Further, the turning of air-permeating hole and No.1 choke plate be fillet, and the turning of air-permeating hole and No. two choke plates is to justify
Angle.
The purpose so designed is, by the way that turning is arranged to fillet, can reduce when air-flow impinges upon choke plate and produce
Raw noise.
Optionally, noise reduction inside pipe wall is coated with sound absorbing layer.
The purpose so designed is that sound absorbing layer absorbs sound, it can be acoustical cotton or impedance complex formula
Abatvoix.
Further, No. two wind-guiding blocks are additionally provided between partition plate and hush pipe, No.1 wind-guiding block one side is connected with partition plate, separately
Simultaneously it is connected with wind turbine organism bottom, inclined-plane is recessed circular arc.
Optionally, No.1 wind-guiding block is additionally provided between partition plate and motor, No.1 wind-guiding block one side connects with wind turbine organism sidewall
Connect, for another side with being connected at the top of wind turbine body, inclined-plane is recessed circular arc.
The purpose so designed is, the air-flow entered by hush pipe is imported wind turbine vane by No.1 wind-guiding block,
Its inclined-plane is recessed circular arc, can reduce air-flow and noise caused by wind turbine internal body protrusion structural impact, make air-flow
Can be steady, the air-flow discharged from wind turbine vane is imported into discharge pipe by No. two wind-guiding blocks, air-flow and wind turbine machine can be reduced
Noise caused by internal portion's protrusion structural impact, allows the flow to steady.
The beneficial effects of the utility model include at least one below；
1st, by setting hush pipe to carry out preliminary noise reduction to the air-flow of entrance in the air intake vent of wind turbine body, at the same by every
Wind turbine body is divided into two parts by plate, and a part is connected with hush pipe, another part is connected with discharge pipe, partition plate with
The spacing of hush pipe is more than the diameter of hush pipe, and the air intake vent of existing wind turbine is since for beauty, often its pipe diameter is much small
In the diameter of wind turbine vane, so when wind turbine vane rotates, other enter larger space due to air-flow from less pipeline
It is unstable easily to produce the sound of similar detonation, so as to produce noise, the straight of hush pipe is more than by the spacing of partition plate and hush pipe
Footpath, i.e. air-flow are just being in larger space before entering wind turbine vane, and noise can be greatly lowered.
2nd, the gas of entrance is realized by rectification by the choke plate of setting and air-permeating hole, the gas of flow velocity inequality is from air-permeating hole
Tend to be close through its rear speed, noise when being greatly reduced into wind turbine vane.
3rd, by the way that the air-permeating hole on two pieces of choke plates is shifted to install, the effect of adjustment gas flow rate can be improved, significantly
It is lowered into noise during wind turbine vane.
4th, by the way that turning is arranged to fillet, air-flow can be reduced and impinge upon noise caused by choke plate.
5th, the air-flow entered by hush pipe is imported by wind turbine vane by No.1 wind-guiding block, its inclined-plane is recessed circle
Arc, can reduce air-flow and noise caused by wind turbine internal body protrusion structural impact, allow the flow to steadily, pass through No. two
The air-flow discharged from wind turbine vane is imported discharge pipe by wind-guiding block, can be reduced air-flow and be protruded structural impact with wind turbine internal body
Caused noise, allows the flow to steady.
