Abstract
The utility model discloses an electric ventilation door for a fan, which is designed mainly for overcoming many deficiencies of ventilation doors for current mining axial ventilating fans started by air pressure. The electric ventilation door for the fan provided by the utility model comprises the fan provided with an air barrel, a ventilation door connected with the air barrel and an electric connecting rod arranged in the air barrel and hinged with a hinge block arranged on the ventilation door. The air barrel is connected with the ventilation door through a door shaft arranged on the air barrel and the air barrel is further internally provided with a stroke switch. The electric ventilation door for the fan provided by the utility model is simple and compact in structure and electrically controlled, has a good controllable effect, and effectively guarantees immediate open and close of the ventilation door and safe operation of the ventilation door.
Description
Technical field
The utility model relates to a kind of blower fan and uses MOD.
Background technology
Mine ventilation is very important in the manufacturing process of a mine link, is directly connected to the personal safety of mine worker and the ordinary production in mine.In the mine ventilation process, need carry out ventilation, need two typhoon machines to be in parallel installed with and be used alternatingly with mining propeller fan; The air door that prevents the air-flow inverted ventilation is installed at fan outlet; With convenient maintenance and maintenance to blower fan, the normal open and close of air door seem particularly important.Owing to can't realize in the tunnel that hydraulic means and personnel are on duty; Domestic most employing blast principle makes air door switch voluntarily under distinguished and admirable effect, thereby plays the inverted ventilation effect that prevents; But this structural performance is unstable; Not only usually take place because air door switch freely influence the phenomenon of ventilating, and increase the blower fan extra duty and be used for opening or closing air door, do not meet the requirement of modern management, intellectuality production.
The utility model content
To the problems referred to above, the utility model provides a kind of control simple and compact for structure, electronic, controlled effective blower fan to use MOD.
For achieving the above object, the utility model blower fan is used MOD, in comprising air door that the blower fan that is provided with air duct, said air duct connect and being arranged on said air duct and the electronic connecting rod that is connected with said air door.
Further, said air duct connects said air door through the door-hinge that is provided with above that.
Further, the hinged block that is provided with on said electronic connecting rod and the said air door is hinged.
Especially, also be provided with travel switch in the said air duct.
Preferably, said air door is a double door.
The utility model blower fan is used MOD, simple and compact for structure, electronic control, controlled effective, and the installation travel switch controls the unlatching of MOD or cuts out in the air duct of blower fan; The motion that electronic connecting rod drives MOD is consistent this air door and the running orbit of this electronic connecting rod; Under the cooperatively interacting of travel switch and electronic connecting rod, the timely open and close and the safe operation of air door have been guaranteed.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with Figure of description the utility model is done further description.
As shown in Figure 1; The utility model blower fan is used MOD; A kind ofly be applied to mine ventilation with the embodiment of propeller fan with air door structure; Preventing of comprising that the propeller fan that is provided with air duct 3, said air duct the connect air door 1 that said axial flow blower air outlet produces the inverted ventilation air-flow be arranged on said air duct in the electronic connecting rod 2 that is connected with said air door; Wherein said air door is the double swing doors of good leak tightness, and said air duct connects said air door through the door-hinge 6 that is provided with above that, and said electronic connecting rod is connected with hinged block 5 on being arranged on said MOD; It is consistent that the running orbit that the running orbit of controlling said MOD makes this MOD and said electronic connecting rod remain, and guarantees the air door security of operation.In addition, also be respectively equipped with the travel switch 4 that the corresponding said MOD of control is opened or closed in the air duct of said axial flow blower, thereby the switch of having stopped air door is smooth, the phenomenon of the energy of the said axial flow blower of consumption.
During use, when the needs MOD is opened, send instruction by travel switch and open MOD, being moved with the track of setting by electronic connecting rod drive MOD is opened to suitable position again; When needs are closed said MOD, send the instruction of closing MOD by travel switch equally, there is electronic connecting rod to drive MOD again and gets back to closed condition with suitable running orbit.That MOD has been controlled in the travel switch acting in conjunction of installing in the electronic air duct of hinged electronic connecting rod and axial flow on the hinged block of MOD and open and close; Make its running orbit of in running, following electronic connecting rod all the time, guaranteed the security of operation of MOD.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
