Abstract
The utility model discloses a ventilation and water prevention structure for a motor, which is mounted on a ventilation opening formed on a frame of the motor and comprises a louver window and a steel mesh, wherein the louver window comprises a window frame and a plurality of louver blades parallelly fixed in the window frame; cross sections of the louver blades are V-shaped; a plurality of drain holes are formed at the bottoms of the louver blades; two ends of each of the louver blades are respectively fixed on the left frame and the right frame of the window frame, so as to enable the louver blades to arrange from up to down sequentially; and the steel mesh is mounted at the inner side end of the window frame. By adopting the ventilation and water prevention structure for the motor, rainwater is prevented from entering into the motor even though the motor does not ventilate or is in an exhaust state, so that the insulation of the motor is guaranteed.
Description
Technical field
The utility model relates to a kind of ventilation waterproof structure of motor.
Background technology
Motor is discharged the internal heat air by the ventilating opening of offering on the support in running, suck extraneous air, and motor is cooled.Therefore in the open outdoor, the operational site of some motor must have to ventilating opening that anti-rainwater drenches, anti-requirement such as dabble.Ventilating opening on the support generally adopts shutter 1 to add the protection mode (see figure 1) of steel wire 2 at present.Shutter 1 comprises window frame 11 and louvre blade 12, because this louvre blade 12 be slab construction, is setting abreast between louvre blade 12 and the louvre blade 12, and every louvre blade 12 is provided with in the mode of 60 ° of window frames about low inside and high outside and the inclination.When motor during with the extraneous air inspiration, suction also can be drawn into base inner together with the part rainwater, and then enters motor internal, and this insulation to motor is very unfavorable.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of ventilation waterproof structure of motor to be provided, and rainwater can not enter motor internal when it can guarantee that motor is drenched with rain, thereby had guaranteed the insulation of motor.
The technical scheme that realizes above-mentioned purpose is: a kind of ventilation waterproof structure of motor, be installed on the ventilating opening of offering on the support of described motor, this ventilation waterproof structure comprises a shutter and a steel wire, described shutter comprises that window frame and multi-disc are fixed on the louvre blade in the window frame abreast, wherein:
The cross section of described every louvre blade is in the shape of the letter V, offer several osculums the bottom interval of every louvre blade, the two ends of described multi-disc louvre blade are separately fixed on the left and right sides frame of described window frame, so that the multi-disc louvre blade is arranged above and below in the mode of a coverage at interval;
Described steel wire is installed in the medial extremity of described window frame.
The ventilation waterproof structure of above-mentioned motor, wherein, the osculum on the described every louvre blade has two at least.
The ventilation waterproof structure of above-mentioned motor, wherein, the V font angle of described every louvre blade is 90 °.
The technical scheme of the ventilation waterproof structure of a kind of motor of the present utility model changes cross section into by the louvre blade with shutter and is in the shape of the letter V, and the bottom interval of every louvre blade offer the plurality of rows water hole.When the part rainwater sucks V font louvre blade with air, upper and lower settings V font louvre blade forms a V font groove, can stop that rainwater enters motor internal, rainwater is contained in the V-shaped valley, simultaneously the osculum of V-shaped valley bottom does not stop enters down rainwater one deck V-shaped valley, finally water is discharged air inlet by the osculum on the undermost louvre blade, rainwater does not enter motor internal when guaranteeing that motor is drenched with rain, more can not make rainwater enter motor internal when motor during stuffy or air draft, thereby guarantee the insulation of motor.

Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 2 to Fig. 4, the ventilation waterproof structure of a kind of motor of the present utility model is installed on the ventilating opening of offering on the support of motor, and this ventilation waterproof structure comprises a shutter 1 and a steel wire 2.Wherein:
Shutter 1 comprises that window frame 11 and multi-disc are fixed on the louvre blade 12 in the window frame 11 abreast;
It is 90 ° V font that the cross section of every louvre blade 12 is angle, offers several osculums 120 bottom interval of every louvre blade 12;
The two ends of multi-disc louvre blade 12 are separately fixed on the left and right sides window frame 111 of window frame 11, so that multi-disc louvre blade 12 is arranged above and below in the mode of a coverage at interval; This coverage is advisable with the air-conditioning requirement that does not influence motor;
In illustrated embodiments, the osculum 120 on every louvre blade 12 is offered two at least.
The operation principle of the ventilation waterproof structure of a kind of motor of the present utility model is: when the part rainwater sucks V font louvre blade 12 with air, upper and lower settings V font louvre blade 12 forms a V font groove, can stop that rainwater enters motor internal, rainwater is contained in the V-shaped valley, simultaneously the osculum 120 of V-shaped valley bottom does not stop enters down rainwater one deck V-shaped valley, finally water is discharged air inlet by the osculum on the undermost louvre blade 12, rainwater does not enter motor internal when guaranteeing that motor is drenched with rain, and more can not make rainwater enter motor internal when motor during stuffy or air draft.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
