Abstract
The utility model discloses a novel axial -flow type fire control fan, including fan shell, motor, a protection section of thick bamboo and wind wheel, being equipped with the stator that links together both between a protection section of thick bamboo and the fan shell, the motor is fixed in a protection section of thick bamboo, and motor shaft one end is stretched out and is protected a section of thick bamboo and wind wheel fixed connection, the fan shell is equipped with the air inlet, and a protection section of thick bamboo is equipped with the air duct of an intercommunication protection section of thick bamboo and air inlet keeping away from wind wheel one side, and a protection section of thick bamboo is being equipped with a plurality of negative pressure hole on one side of the wind wheel being close to. Compared with the prior art, the utility model discloses a be equipped with the air inlet at the fan shell, a protection section of thick bamboo is equipped with the air duct of an intercommunication protection section of thick bamboo and air inlet keeping away from wind wheel one side, and a protection section of thick bamboo is being equipped with a plurality of negative pressure hole being close to wind wheel one side, forms a negative pressure when wind wheel rotates in the protection section of thick bamboo, again from the negative pressure hole cooling system of formation that discharges, has the advantage of simple structure, reduction in production cost and energy -conservation after cooling air gets into the air duct and cools off the motor in the leading -in protection section of thick bamboo from the air inlet of fan shell.
Description
Technical field
This utility model relates to Novel firefighting device, particularly to a kind of novel axial-flow type firefighting fan.
Background technology
Traditional firefighting fan includes blower housing, motor, protection cylinder and wind wheel; wind wheel is contained in machine shaft one end; the other end loads onto a centrifugal impeller; protection tube rear end is provided with one and extends to bend pipe outside casing; forcing during centrifugal impeller work, from bend pipe, the importing of new wind is cooled down motor, there is structure complexity, production cost height and the shortcoming adding energy consumption of electrical machinery in above-mentioned firefighting fan.
Utility model content
Main purpose of the present utility model is in that to provide a kind of simple in construction, reduce production cost and energy-conservation novel axial-flow type firefighting fan.
For achieving the above object; the technical scheme that this utility model adopts is: a kind of novel axial-flow type firefighting fan; including blower housing, motor, protection cylinder and wind wheel; it is provided with stator between protection cylinder and blower housing; motor is fixed in protection cylinder; machine shaft one end is stretched out protection cylinder and wind wheel and is fixed and be connected; described blower housing is provided with air inlet; protection cylinder is being communicated with the airway of protection cylinder and air inlet away from wind wheel side, and protection cylinder is being provided with several negative pressure holes near wind wheel side.
Compared with prior art; this utility model is by being provided with air inlet at blower housing; protection cylinder is being communicated with the airway of protection cylinder and air inlet away from wind wheel side; protection cylinder is being provided with several negative pressure holes near wind wheel side; negative pressure is formed in protection cylinder when wind wheel rotates; cooling air imports from the air inlet entrance airway of blower housing to discharge from negative pressure hole again after motor being cooled down in protection cylinder again and forms a cooling system, has simple in construction, reduces production cost and energy-conservation advantage.
As the improvement of such scheme, several negative pressure holes described are located on the circumferential side wall of protection cylinder.
As the improvement of such scheme, several negative pressure holes described are evenly distributed on the circumferential side wall of protection cylinder.
As the improvement of such scheme, described negative pressure hole is 1��6.
As the improvement of such scheme, described airway cross section is rugby shape. Airway cross section is that rugby shape can be substantially reduced aerodynamic noise and improve the efficiency of blower fan.
Accompanying drawing explanation
Fig. 1 is a kind of axial-flow type firefighting fan structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish. The embodiment described below with reference to accompanying drawing is illustrative of, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Specifically describe according to this utility model embodiment below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2; a kind of novel axial-flow type firefighting fan of the present utility model; including blower housing 1, motor 2, protection cylinder 3 and wind wheel 4; it is provided with stator 5 between protection cylinder 3 and blower housing 1; motor 2 is fixed in protection cylinder 3, and motor 2 rotating shaft one end is stretched out protection cylinder 3 and wind wheel 4 and fixed and be connected, and blower housing 1 is provided with air inlet 11; protection cylinder 3 is being communicated with the airway 6 of protection cylinder 3 and air inlet 11 away from wind wheel 4 side, and protection cylinder 3 is being provided with multiple negative pressure hole 31 near wind wheel 4 side.
Preferably, multiple negative pressure holes 31 are located on the circumferential side wall of protection cylinder 3.
Preferably, multiple negative pressure holes 31 are evenly distributed on the circumferential side wall of protection cylinder 3.
Preferably, negative pressure hole 31 is 1 to 6.
Preferably, airway 6 cross section is rugby shape. Airway 6 cross section is that rugby shape can be substantially reduced aerodynamic noise and improve the efficiency of blower fan.
The operation principle of a kind of novel axial-flow type firefighting fan of the present utility model is as follows: during the work of axial-flow type firefighting fan; wind wheel 4 rotates and makes to be formed in protection cylinder 3 negative pressure; cooling air from the air inlet 11 of blower housing 1 enter airway 6 imports again in protection cylinder 3, motor 2 is cooled down after discharge from negative pressure hole 31 again and form a cooling system, there is simple in construction, reduction production cost and energy-conservation advantage.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
