【Specific implementation mode】
Technical solutions of the utility model are described in further detail below in conjunction with Figure of description, it is notable that Following specific examples is only to illustrate the technical solution of the utility model, and non-limiting.
Referring to attached drawing 1 to 3, a kind of positive draft switchgear house includes the air inlet for being connected to switchgear house 10 and exterior space Portion 20.The inlet section 20 includes blast pipe 21, filter house 22, elastic component 23 and wind turbine 24, and blast pipe 21 runs through switchgear house 10 Wall sets up in blast pipe 21 to be connected to switchgear house 10 and exterior space and is equipped with wind turbine 24, when wind turbine 24 operates, outside Portion's air draught is flowed into from blast pipe 21 in switchgear house 10.Pass through elastic component 23 and filter house 22 at the air inlet port of blast pipe 21 Elastic connection, when elastic component 23 is pressurized, the lid of filter house 22 seals air inlet port, and filter house 22 is to the sundries in air draught Filtering intercepts.In the present embodiment, the filter house 22 is composed of filter screen and filter cloth, the covering filtering of filter screen outer layer Cloth.
Such as Fig. 2, blind hole 211 is radially offered at the air inlet port of blast pipe 21.23 one end of the elastic component is fixed on 211 bottom surface of blind hole, the other end are fixedly connected with the filter house 22, and the length of elastic component 23 is longer than 211 depth of blind hole, elastic component Expose blind hole 211.Wherein, the elastic component 23 can be spring, and length is longer than 211 depth of blind hole, and spring exposes blind hole 211.Further, in order to obtain more stable filter effect, it is described blind that the air inlet port of blast pipe 21 is provided with several Hole 211 is provided with the spring for being fixedly connected with blast pipe 21 and filter house 22 at each blind hole 211.
Wind turbine 24, which is powered, to be operated, and the air draught outside switchgear house 10 enters switchgear house 10, and switchgear house 10 compares external pressure It is higher, prevent inflammable and explosive property gas from slipping into switchgear house 10.When wind turbine 24 operates, elastic component 23 is squeezed by filter house 22, filtering 21 port of blast pipe is close in portion 22, and filter house 22 is filtered interception to impurity in outer air stream;When wind turbine 24 stops transporting Turn, elastic component 23 is acted on by elastic restoring force, and filter house 22 vibrates back and forth with elastic component 23, remains in the sundries quilt of filter house 22 Oscillation is fallen down, the remaining sundries without artificial processing filter house 22.The remaining of filter house 22 is preferably handled in order to obtain The effect of sundries, 24 intermittence of wind turbine shut down, and stop frequency is pressed depending on actual conditions.
Such as Fig. 3, which further includes having intelligence control system 30, control system 30 include controller 31, First pressure sensor 32 and second sensor 33.The controller 31 is pressed with the first pressure sensor 32, second respectively Force snesor 33 and wind turbine 24 are electrically connected.The first pressure sensor 32 is incited somebody to action to sense the atmospheric pressure value in switchgear house 10 Atmospheric pressure value feeds back to controller 31, and second pressure sensor 33 is to sense the atmospheric pressure value outside switchgear house 10, and by atmospheric pressure value Feed back to controller 31.
Power on, controller 31 is started to work, and controller 31 controls wind turbine 24 and starts running, and is provided just for switchgear house 10 Press strip part, every N time intervals, controller 31 controls wind turbine 24 and shuts down, the oscillation removing sundries of filter house 22, in switchgear house 10 Atmospheric pressure value declines, and controller 31 judges the draught head of switchgear house 10 and exterior space, and when draught head is 0, controller 31 controls Wind turbine 24 operates again.
In another embodiment, the switchgear house 10 is also equipped with another air inlet being oppositely arranged with the inlet section 20 Portion 20, two inlet sections 20 being oppositely arranged are that switchgear house 10 provides positive pressure, when the wind turbine 24 of a wherein inlet section 20 stops When operating, in order to obtain the positive pressure stablized in switchgear house 10, the wind turbine 24 of another inlet section 20 increases running speed, makes up The air pressure of loss.
