See fig. 1 and 3.

As shown in fig. 1, the utility model provides a waterproof permanent magnet motor, including casing 1, the rotor 2 of setting in casing 1, the pivot 3 of being connected with rotor 2 and install sealed bearing 4 at 3 both ends of pivot, still include:

the moisture-proof disc 5 is sleeved on the rotating shaft 3 and is positioned on one side of the corresponding shell 1 of the sealing bearing 4, the moisture-proof disc 5 rotates along with the rotating shaft 3, and a drying agent 6 is arranged in the moisture-proof disc 5 and used for absorbing water vapor in the shell 1.

In the concrete implementation, because of the invasion of the unable thoroughly isolated steam of sealed bearing 4 at 3 both ends of pivot, consequently, set up dampproofing dish 5 through sealed bearing 4 department in casing 1, the steam that invades in the casing 1 can be absorbed by drier 6 in the dampproofing dish 5 to this dry condition in maintaining casing 1 for a long time, the life of extension motor can be in the periodic maintenance stage of motor, change drier 6 in the dampproofing dish 5, make dampproofing dish 5 can play a role all the time.

Wherein, the desiccant 6 can be solid granular desiccant 6, such as molecular sieve desiccant 6, mineral desiccant 6; it may also be a powdered desiccant 6, such as lime powder. The solid granular drying agent 6 is the most preferred embodiment, and since the drying agent 6 is various and common knowledge in the prior art, the style of the drying agent 6 is not listed here.

As shown in fig. 3, the moisture proof disk 5 is formed in a disk shape, and the moisture proof disk 5 is coaxial with the rotation shaft 3. Thus, when the moisture-proof disc 5 is driven by the rotating shaft 3 to rotate, the rotating center of the moisture-proof disc is coaxial with the rotating shaft 3, and large vibration cannot be caused.

Specifically, the moisture-proof disc 5 comprises a disc body 51 and a disc cover 52, wherein the disc body 51 is in a groove shape and is used for containing the desiccant 6, the disc cover 52 is arranged at an opening of the disc body 51 in a covering mode and is used for preventing the desiccant 6 in the disc body 51 from leaking outwards and allowing water vapor to enter the disc body 51 through the disc cover 52, and the disc cover 52 faces to one side of the corresponding sealed bearing 4. The cover 52 is a grating plate or a cover plate with a plurality of air holes, a water-absorbing film 53 is disposed on one side of the cover 52 corresponding to the plate body 51, and the film 53 can prevent the chips of the desiccant 6 from leaking out of the cover 52 and keep the inside of the housing 1 clean.

In specific implementation, when moisture invades into the shell 1, the humidity at the position of the sealing bearing 4 is the largest, so that the disc cover 52 faces the sealing bearing 4, the moisture directly faces the disc cover 52 after invading into the shell 1, and the moisture is captured by the drying agent 6 in the disc body 51 after passing through the disc cover 52, and the moisture is intercepted and captured from the source.

As shown in fig. 1, a raised shoulder 31 is provided at a position corresponding to the moisture-proof disc 5 on the rotating shaft 3, and the shoulder 31 is in spacing fit with the moisture-proof disc 5. Can prevent like this that dampproofing dish from along the axial displacement of pivot, avoid the distance grow between dampproofing dish and the sealed bearing, dampproofing dish influences the capture to steam.

As shown in fig. 1 and 2, a fan housing 7 is disposed at the tail of the housing 1, one end of the rotating shaft 3 extends out of the housing 1 to the inside of the fan housing 7, and one end of the rotating shaft 3 located in the fan housing 7 is provided with a fan blade 8;

the wind shield 7 is further provided with a wind disturbing component 9, and the wind disturbing component 9 comprises a base plate 91 sleeved on the position of the corresponding sealing bearing 4 on the rotating shaft 3 and a plurality of blades 92 uniformly distributed on the base plate 91.

In specific implementation, the rotation of the rotating shaft 3 drives the fan blades 8 to make external air flow enter the fan cover 7 and blow towards the shell 1, so as to cool the motor. Contain steam in the air current because of getting into in the fan housing 7, thereby in the invasion of avoiding steam to take advantage of the wind speed to accelerate to sealed bearing 4 gets into the box body, through set up wind disturbing part 9 in sealed bearing 4 department, the rotation of pivot 3 drives wind disturbing part 9 and rotates, wind disturbing part 9 is when rotating, can produce vortex wind around it, vortex wind can disturb the wind that flows towards sealed bearing 4 department and block, the wind of avoiding containing steam blows directly to sealed bearing 4, delay the speed in steam entering box body.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
