Specific embodiment
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail.
Embodiment: referring to Fig. 1, Fig. 2, a kind of lift car automatic ventilation fan, including shell 1, motor 2 and flabellum 3.Institute
Stating shell 1 is horizontally disposed rectangular parallelepiped structure, and the four corners on the downside of shell are respectively equipped with a Rubber shock-absorbing pad 8；Such energy
The vibration generated by draft fan work is enough effectively reduced, to further decrease the noise generated when elevator operation.In shell 1
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, which operates, simultaneously drives flabellum 3 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.
In assembly use process referring to Fig. 3 above-mentioned lift car automatic ventilation fan, the temperature-detecting device and red
Outer line detector is connected with electric life controller, and the electric life controller is connected to the motor after blast regulator.It is specific
Control process is as follows:
1) self-test is carried out after elevator starting；Start elevator operation after self-test.
2) elevator operate normally when, by infra-red ray detection device detect carriage in whether someone, if someone, elevator control
Device processed controls draft fan by blast regulator and is actuated for divulging information.
3) temperature detection in carriage is carried out by temperature-detecting device, then electric life controller area depending on the temperature
Between the ventilation of corresponding air quantity is carried out by blast regulator.Wherein, the draft fan is divided into fourth gear according to air output from small to large,
The temperature that wherein temperature detector detects corresponding outlet air when corresponding air output is one grade, 10-20 DEG C when being 10 DEG C or less
Amount when be two grades, 20-30 DEG C corresponding air output be third gear, 30 DEG C or more whens, corresponding air output was fourth gear；In such manner, it is possible to more
The energy consumption of elevator operation is reduced well, and improves the comfort of boarding.
4) when elevator, which breaks down, shuts down, if carriage someone that infra-red ray detection device detects, electric life controller
The signal detected according to infra-red ray detection device controls draft fan restarting by blast regulator；Meanwhile elevator controlling
Device sends elevator rescue alarm signal to middle control or maintenance staff.
When temperature-detecting device detects that carriage temperature is higher, electric life controller is issued a signal to, electric life controller turns
Order is issued to blast regulator after changing signal, and blast regulator improves motor rotation speed according to instruction, to increase draft fan
Air output；When temperature-detecting device detects that carriage temperature is lower, electric life controller, which issues to enable, arrives blast regulator, air quantity tune
Saving device reduces motor rotation speed according to instruction, to reduce draft fan air output.
When elevator faults stop ladder, cab interior illumination, the wholly off operation of fan；At this point, if infrared sensor is examined
Measuring cab interior has passenger, issues a signal to electric life controller immediately, and electric life controller issues instructions to wind after receiving signal
Adjuster is measured, blast regulator is restarted according to instruction control draft fan, guarantees car ventilation；Meanwhile central processing unit is straight
Sending and receiving go out to rescue alarm signal to middle control or maintenance staff or gate sentry, security personnel etc., accurately rescue to be conveyed to refer in time
It enables, ensures that rescue is timely.
Finally, it should be noted that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application technology
Scheme, those skilled in the art should understand that, those are modified to the technical solution of the utility model or are equal
Replacement, without departing from the objective and range of the technical program, should all cover in the scope of the claims of the utility model.
