Abstract
The invention discloses a kind of shutter used for electric motor, including window frame and many gates leaf, described many gates leaf is vertically arranged with the spacing less than 1mm successively, and is fixed in described window frame, the cross section undulate of described window leaf.Present configuration is simple, convenient for installation and maintenance, it is possible to prevent dabbling of any direction not enter in electric machine casing, owing to window leaf uses frivolous steel plate bending to be vertically welded, meet and under the function premise of the anti-foreign body of waterproof, have enough ventilation and heat areas, meet the requirement of IP24 degree of protection；Owing to employing integral frame structure, and louver board is welding after inserting one by one, whole shutter good rigidly, is unlikely to deform.
Description
Technical field
The invention belongs to electrical generator fields, particularly relate to a kind of shutter used for electric motor.
Background technology
Motor used in blinds is in ventilating for motor radiating, and conventional motors shutter generally adopts transverse vane type oblique weld structure, can prevent the diameter solid foreign materials more than 12mm from entering in shell, and prevent plumb line from becoming the trickle in 60 ° of angle ranges without adverse effect.
Requirement according to GB (GB4942.1), the shutter of IP24 degree of protection motor need to prevent the diameter solid foreign materials more than 1mm from entering in shell and can bear the dabbling without adverse effect of any direction, and traditional motor shutter cannot meet the requirement of IP24 degree of protection.
Summary of the invention
Based on this, for above-mentioned technical problem, it is provided that a kind of shutter used for electric motor.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of shutter used for electric motor, including window frame and many gates leaf, described many gates leaf is vertically arranged with the spacing less than 1mm successively, and is fixed in described window frame, the cross section undulate of described window leaf.
Wherein in an embodiment, the spacing between described window leaf is 0.3mm.
Wherein in an embodiment, the cross section of described window leaf is W-shaped.
Wherein in an embodiment, also including silk screen, described silk screen is fixed on rear side of described window frame.
Wherein in an embodiment, described silk screen is four order silk screens.
Present configuration is simple, convenient for installation and maintenance, it is possible to prevent dabbling of any direction not enter in electric machine casing, owing to window leaf uses frivolous steel plate bending to be vertically welded, meet and under the function premise of the anti-foreign body of waterproof, have enough ventilation and heat areas, meet the requirement of IP24 degree of protection；Owing to employing integral frame structure, and louver board is welding after inserting one by one, whole shutter good rigidly, is unlikely to deform.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the A-A sectional view of the present invention.
Detailed description of the invention
As it is shown in figure 1, a kind of shutter used for electric motor, including window frame 11, many gates leaf 12 and silk screen 13.
The cross section undulate of window leaf 12, as in figure 2 it is shown, adopt the wavy shaped configuration of W shape herein.Window leaf 12 is formed by frivolous steel plate bending.
Many gates leaf 12 is vertically arranged with the spacing less than 1mm successively, and is fixed in window frame 11, and after every gate leaf 12 inserts window frame 11, upper and lower side is all fixed with window frame 11 upper and lower side frame electric welding.It is possible to prevent dabbling of any direction not enter motor internal.
Herein, the line space design between window leaf 12 is 0.3mm, can reach preferably effect.
As in figure 2 it is shown, 1Cr18Ni9 rustless steel four order silk screen selected by silk screen 13, it is fixed on the rear side of window frame 11, it is possible to is entirely prevented from the diameter solid foreign materials more than 1mm and enters in shell.
But, those of ordinary skill in the art will be appreciated that, above embodiments is intended merely to the explanation present invention, and it is not used as limitation of the invention, as long as in the spirit of the present invention, to the change of embodiment described above, modification all by the Claims scope dropping on the present invention.
Claims (4)
