Interior horizontal equipped with a sharf, the sharf is located at the middle part of shell 1, and both ends pass through the both ends of bearing Yu shell 1 respectively
It is connected.The motor 2 is installed on one end of shell 1, and 2 axis of motor is connected by shaft coupling with sharf；When it is implemented, institute
It states motor 2 to be connected by mounting bracket with shell 1, sharf passes through shaft coupling and electricity after one end of motor 2 stretching shell 1
2 axis of machine is connected；The installation of motor 2 and motor 2 and the connection of sharf are more convenient in this way.The flabellum 3 is installed on the leaf
On bobbin, sharf is able to drive by motor 2 and flabellum 3 rotates；Wherein, the length direction of the flabellum 3 and sharf
Length direction is consistent, width direction and sharf it is radially consistent.
It is provided with several air inlet holes 4 on the both side plate of the shell 1, the both side plate of shell 1 is made to form hollowed-out board；Specific implementation
When, strip-shaped hole that the air inlet hole 4 is vertically arranged；To keep the area of air inlet bigger, intake can effectively ensure that.?
The downside of shell 1 is provided along its length an air outlet, is equipped with a wind deflector 5 vertically respectively in the two sides of air outlet；Two lead
Air-out passage is formed between aerofoil 5.For the flow direction for being further ensured that wind, it is respectively equipped with a baffle in the two sides of air-guiding aisle, it should
Baffle is connected with two wind deflectors, 5 end；To make air-out passage form enclosed construction.Temperature is equipped between two wind deflectors 5 to examine
It surveys device 6 and infra-red ray detection device 7, the temperature-detecting device 6 and infra-red ray detection device 7 is respectively arranged in wind deflector 5
On；When it is implemented, temperature-detecting device 6 and infra-red ray detection device 7 are installed on the lower part of the opposite side of two wind deflectors 5,
And respectively close to the both ends of shell 1；In such manner, it is possible to make the easier for installation of draft fan, and detection effect is more preferable.Wherein,
The temperature-detecting device 6 is temperature sensor；Cost is lower, and it is more preferable to detect stability.
This draft fan reserves air inlet in car top, air outlet and car top when in use, by draft fan setting
Docking, when work：Motor 2 operates and flabellum 3 is driven to rotate, and air enters inside fan from the enterprising air holes 4 of hollowed-out board, from wind-guiding
The air-out passage formed between plate 5 enters carriage.
Referring to Fig. 3, a kind of control method based on above-mentioned lift car automatic ventilation fan, the temperature-detecting device and infrared
Line detector is connected with electric life controller, and the electric life controller is connected to the motor after blast regulator.It is specifically controlled
