Description
Technical field
This utility model relates to a kind of motor, particularly a kind of motor shield.
Background technology
Under some specific conditions, motor must be positioned in water and operate, and existing motor self is waterproof
Performance does not reaches the most far away this requirement, so by some external instruments waterproof effect must reach, but this situation
Under often motor be closed under water, the heat dispersion of motor is excessively poor, have impact on the normal operation of motor, even can bring peace
Full hidden danger.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, it is provided that one is prevented from water and enters into protective cover
The motor shield of good heat dispersion performance in inside and protective cover.
Technical scheme: for achieving the above object, this utility model provides a kind of motor shield, including for placing motor
Protective cover, the end face of described protective cover is provided with at least two ventilation duct, the exit of described ventilation duct is provided with ventilation
Lid, described cowling offers some air vents, and a side of described protective cover and the end face of protective cover are by roller bearing phase
Even, the side of the described protective cover being connected with roller bearing is provided with screwed hole, described protection with the contact jaw of the bottom surface of protective cover
The side of cover coordinates the fixing bolt in screwed hole to fix with the underrun of protective cover and is connected, and the rotating shaft of described motor is from anti-
The side of guard shield is protruding.
Design principle of the present utility model is: by stretching out outside the water surface by the ventilation duct on protective cover so that extraneous and anti-
Guard shield inner air can be circulated by the air vent on cowling, has preferably so that be positioned at protective cover under water
Heat dispersion, and also be able to ensure water will not enter in protective cover.
Further, being provided with filter screen in described ventilation duct, filter screen can filter out the dust in air and some are tiny
Magazine, it is to avoid in protective cover, dust accumulation affects the normal operation of motor.
Further, the quantity of described ventilation duct is three.
Further, described rotating shaft is provided with rubber seal with the contact surface of the side of protective cover, rubber seal
Arrange and make that there is between rotating shaft and protective cover fabulous sealing, it is to avoid water enters from the gap between rotating shaft and protective cover
Inside protective cover.
Beneficial effect: this utility model compared with prior art, ensure that water will not enter into the feelings within protective cover
Under condition, protective cover is internal itself has also possessed good ventilation and heat performance, thus improves the work of motor operation under water
Make efficiency, eliminate because heat cannot disperse the potential safety hazard brought, extend the service life of motor the most further.
