Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electric motor, and particularly relates to a mine-used electric motor. BACKGROUND

[0002] The coal seam is usually located near the underground aquifer, and the underground water in the rock fissure continuously seeps into the roadway, resulting in the increase of ground and air humidity. Due to geological structure such as fault and landslide zone, the water seepage of some mines is intensified, and even water accumulation is formed in local area. Although the temperature of the underground rock is increased with the increase of depth due to the influence of geothermal gradient, the relative humidity of the shallow mine is often above 95%, and even up to 100% in some areas.

[0003] The condensation temperature of the moisture depends on the dew point temperature of the air, that is, the critical temperature at which the water vapor in the air reaches saturation and begins to condense. The dew point temperature is determined by the actual temperature and relative humidity of the air, and is not a fixed value. For example, in the air with a temperature of 20℃ and a relative humidity of 90%, the water vapor will condense on the surface below 18.3℃.

[0004] At this time, the dust prevention of the electric motor is extremely important. In combination with the humid environment in the mine, the high-power and high-heat electric motor, such as the hoist, will adopt liquid cooling heat dissipation to lead out the heat inside the electric motor. However, this method is easy to produce condensed water in the low-temperature parts such as the cooling flow passage wall surface and bearing sealing ring in the condensation risk area, so the sealing requirement of the electric motor is extremely high.

[0005] At present, when the high-power electric motor is applied in the mine, only the sealing device such as the sealing ring is used to isolate the inside and outside of the electric motor. The condensed water around the bearing sealing ring of the electric motor may enter the inside of the electric motor. These condensed water will reduce the insulation resistance between the windings, cause high-voltage breakdown, have the risk of short circuit and electric leakage, and also corrode the copper winding under the electric field, and even immerse in the lubricating grease to form emulsion, resulting in lubrication failure and aggravation of wear and tear, and poor safety.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a mine-used electric motor.

[0007] The information disclosed in this BACKGROUND section is only intended to increase an understanding of the general background of the application and should not be taken as an acknowledgement or any form of suggestion that this information forms prior art that is already known to those of ordinary skill in the art.

DETAILED DESCRIPTION

[0031] In order to make the personnel in the technical field better understand the technical solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by the person of ordinary skill in the art without making creative labor should belong to the protection scope of the present disclosure.

[0032] As Figures 1 to 7As shown, the mine motor in the embodiment of the present application comprises: a motor body 1, a centrifugal protection mechanism 2, a barrier guide mechanism 3 and a dehumidification mechanism 4. The motor body 1 is fixedly installed with a motor mounting shaft 11 on one side. The centrifugal protection mechanism 2 is arranged on one side of the motor body 1, and comprises a centrifugal protection bin 21, a centrifugal moisture absorption assembly 22 and a centrifugal power assembly 23. The centrifugal protection bin 21 is installed on the motor mounting shaft 11, can effectively protect various structures in the centrifugal protection bin 21, reduces the damage of various structures in the centrifugal protection bin 21, improves the sealing degree in the centrifugal protection bin 21, and reduces the probability of moisture entering the centrifugal protection bin 21. The centrifugal moisture absorption assembly 22 is fixedly installed in the centrifugal protection bin 21, can act on the moisture in the centrifugal protection bin 21 through centrifugal force, can make the moisture be thrown to the periphery of the centrifugal protection bin 21, and effectively reduces the moisture in the central part of the centrifugal protection bin 21, that is, the bearing sealing ring of the motor body 1. The centrifugal power assembly 23 is fixedly installed on one side of the motor body 1, can provide corresponding power for the rotation of the centrifugal protection bin 21, and can provide corresponding controllability for the centrifugal protection bin 21. The barrier guide mechanism 3 is fixedly installed on the motor body 1, can effectively seal the centrifugal protection bin 21, reduces the interaction of air in the centrifugal protection bin 21 and external air, reduces the entry of external moisture when the air in the centrifugal protection bin 21 is dried, can protect the periphery of the bearing sealing ring of the motor body 1, can isolate the air exchange between the periphery of the bearing sealing ring of the motor body 1 and the outside, and further reduces the moisture gathering around the bearing sealing ring of the motor body 1. The dehumidification mechanism 4 is fixedly installed on the motor body 1, can effectively collect the moisture in the centrifugal protection bin 21 when the moisture gathers in the centrifugal protection bin 21, and discharge the moisture in the centrifugal protection bin 21, so that the moisture in the centrifugal protection bin 21 can no longer flow back.

[0033] The use method of the mine motor is as follows: the centrifugal protection bin 21 is driven to rotate by the centrifugal power assembly 23, the centrifugal moisture absorption assembly 22 is synchronously driven to rotate by the centrifugal protection bin 21, the moisture can be absorbed when the moisture exists in the centrifugal moisture absorption assembly 22, the centrifugal force is generated through rotation, the moisture is thrown out and collected by the centrifugal protection bin 21, the air in the centrifugal protection bin 21 can be absorbed by the barrier guide mechanism 3 and injected into the centrifugal protection bin 21 again, the moisture around the bearing sealing ring is guided through the circulation of the air, and the dehumidification mechanism 4 can suck out the moisture in the centrifugal protection bin 21, reducing the residue of the moisture.

[0034] As Figures 1 to 5As shown, the motor mounting shaft 11 penetrates the centrifugal protection bin 21, which can position the centrifugal protection bin 21 and not affect the centrifugal protection bin 21 when the motor mounting shaft 11 rotates, thereby reducing the possibility of the centrifugal protection bin 21 being driven by the motor mounting shaft 11, not affecting the normal installation of the motor mounting shaft 11, reducing the influence on the normal operation of the motor body 1, improving the stability of the operation of the motor body 1, and reducing the driving of the centrifugal protection bin 21 by the rotation of the motor mounting shaft 11, thereby reducing the mutual influence of the motor mounting shaft 11 and the centrifugal protection bin 21, improving the rotation stability of the centrifugal protection bin 21, and making the rotation of the centrifugal protection bin 21 more stable.

[0035] The centrifugal protection bearing 211 is installed between the motor mounting shaft 11 and the centrifugal protection bin 21, which can position the centrifugal protection bin 21 and reduce the friction between the motor mounting shaft 11 and the centrifugal protection bin 21, thereby effectively improving the service life of the motor mounting shaft 11 and the centrifugal protection bin 21, improving the operation stability of the motor mounting shaft 11, reducing the vibration caused by wear, and effectively improving the smoothness of the motor mounting shaft 11.

[0036] As shown, Figures 1 to 4 The centrifugal moisture absorption assembly 22 includes centrifugal moisture absorption cotton 221 and a plurality of centrifugal moisture absorption rollers 222. The centrifugal moisture absorption cotton 221 is fixedly installed in the centrifugal protection bin 21 and can absorb moisture in the centrifugal protection bin 21, thereby reducing the moisture in the centrifugal protection bin 21 and the possibility of moisture entering the motor body 1, providing a certain guarantee for the sealing of the motor body 1, reducing the accumulation of moisture around the bearing sealing ring of the motor body 1, reducing the corrosion of the bearing sealing ring by condensed water, improving the service life of the bearing sealing ring of the motor body 1, thereby reducing the probability of the bearing sealing ring of the motor body 1 leaking moisture, effectively avoiding the entry of external moisture into the motor body 1, effectively improving the operation safety of the motor body 1, and thereby reducing the risk of damage to the motor body 1. The plurality of centrifugal moisture absorption rollers 222 are arranged in the centrifugal moisture absorption cotton 221 and can extrude the centrifugal moisture absorption cotton 221, so that the moisture absorbed in the centrifugal moisture absorption cotton 221 is extruded, and through the cooperation of the centrifugal force, the water can be thrown out, the centrifugal moisture absorption cotton 221 can absorb moisture again, the centrifugal moisture absorption cotton 221 can be circulated multiple times, the situation of excessive moisture cannot be absorbed is reduced, the centrifugal moisture absorption cotton 221 can absorb moisture more efficiently, and the formation of condensed water is reduced.

[0037] As shown, Figures 1 to 6As shown, the centrifugal moisture absorption roller 222 matches the centrifugal moisture absorption cotton 221, which facilitates the extrusion of the centrifugal moisture absorption roller 222 on the centrifugal moisture absorption cotton 221, makes the extrusion of the centrifugal moisture absorption roller 222 on the centrifugal moisture absorption cotton 221 more comprehensive, and at the same time improves the area of the centrifugal moisture absorption cotton 221 subjected to the extrusion of the centrifugal moisture absorption roller 222, so that the centrifugal moisture absorption cotton 221 can absorb more moisture, thereby reducing the free moisture in the centrifugal protection bin 21, and more moisture can be absorbed by the centrifugal moisture absorption cotton 221.

[0038] In addition, the centrifugal moisture absorption bracket 223 is rotatably installed in the centrifugal moisture absorption roller 222, which can position the centrifugal moisture absorption roller 222 and support the centrifugal moisture absorption roller 222, thereby providing corresponding support for the rotation of the centrifugal moisture absorption roller 222. The centrifugal moisture absorption bracket 223 is fixedly installed with the motor body 1, which can improve the stability of the centrifugal moisture absorption bracket 223 and reduce the probability of disengagement of the centrifugal moisture absorption bracket 223. The centrifugal moisture absorption roller 222 can effectively support the centrifugal moisture absorption cotton 221, and the centrifugal moisture absorption bracket 223 can support the centrifugal moisture absorption roller 222 to rotate. When the centrifugal moisture absorption cotton 221 is driven to rotate by the centrifugal protection bin 21, the centrifugal moisture absorption roller 222 can be effectively rubbed, and the centrifugal moisture absorption bracket 223 can be displaced relative to the centrifugal moisture absorption roller 222 to drive the rotation of the centrifugal moisture absorption roller 222, thereby reducing the damage of the centrifugal moisture absorption roller 222 to the centrifugal moisture absorption cotton 221.

[0039] As shown in FIG. 6, the centrifugal moisture absorption roller 222 is rotatably installed in the centrifugal protection bin 21, and the centrifugal moisture absorption roller 222 is rotatably installed in the centrifugal protection bin 21. Figures 1 to 5As shown, the centrifugal power assembly 23 includes a centrifugal power motor 231, a centrifugal power driven wheel 232, a centrifugal power driving wheel 233 and a centrifugal power transmission belt 234. The centrifugal power motor 231 is fixedly installed on one side of the motor body 1, and can drive the rotation of the centrifugal power driving wheel 233, providing corresponding power for the rotation of the centrifugal power driving wheel 233, making the rotation of the centrifugal power driving wheel 233 more controllable, and enabling the centrifugal power driving wheel 233 to control the operation of the centrifugal power transmission belt 234. The centrifugal power driven wheel 232 is fixedly installed on the side of the centrifugal protection bin 21 away from the motor body 1, and can be driven by the centrifugal power driving wheel 233, and through the fixed connection with the centrifugal protection bin 21, provides corresponding power for the rotation of the centrifugal protection bin 21. The centrifugal power driving wheel 233 is fixedly installed on one side of the centrifugal power motor 231, and can be driven by the centrifugal power motor 231 to rotate, and at the same time can drive the centrifugal power transmission belt 234, so that the centrifugal power transmission belt 234 drives the centrifugal power driven wheel 232 to rotate. The centrifugal power transmission belt 234 is sleeved and installed on the centrifugal power driven wheel 232 and the centrifugal power driving wheel 233, and connects the centrifugal power driven wheel 232 and the centrifugal power driving wheel 233, so that the centrifugal power driving wheel 233 can drive the rotation of the centrifugal power driven wheel 232, and at the same time plays a synchronous role, so that the centrifugal power driven wheel 232 and the centrifugal power driving wheel 233 have the same rotating speed.

[0040] As shown in Figures 1 to 6 The barrier guiding mechanism 3 includes a barrier guiding ring 31 and a barrier airflow assembly 32. The barrier guiding ring 31 is fixedly installed on the motor body 1 and matches the centrifugal protection bin 21. The barrier guiding ring 31 can close the centrifugal protection bin 21, reduce the probability of moisture entering the centrifugal protection bin 21, improve the dryness degree in the centrifugal protection bin 21, and at the same time, reduce the exchange of air between the outside and the centrifugal protection bin 21, reduce the moisture entering the centrifugal protection bin 21, and more effectively improve the dryness degree in the centrifugal protection bin 21. The barrier airflow assembly 32 is fixedly installed on the side of the barrier guiding ring 31 away from the centrifugal protection bin 21, can guide the air from the center of the centrifugal protection bin 21 to the periphery of the centrifugal protection bin 21, and can effectively avoid the gathering of moisture around the bearing sealing ring of the motor body 1, thereby avoiding the condensate water around the bearing sealing ring of the motor body 1.

[0041] As shown in Figures 1 to 3As shown, the barrier airflow assembly 32 includes a barrier air pump 321, a barrier sealed bin 323, a barrier communication pipe 324 and a pair of barrier sealing rings 322. The barrier air pump 321 is fixedly installed on the barrier guide ring 31 and can extract air in the centrifugal protection bin 21 and inject the air into the barrier communication pipe 324. At the same time, the barrier air pump 321 is arranged on the upper side of the barrier guide ring 31, and a certain amount of moisture is gathered at the bottom of the centrifugal protection bin 21, which effectively avoids the probability of the barrier air pump 321 extracting moisture, effectively improves the service life of the barrier air pump 321, reduces the probability of damage of the barrier air pump 321, and improves the operation stability of the barrier air pump 321. A pair of barrier sealing rings 322 are fixedly installed on the side of the centrifugal protection bin 21 away from the motor body 1, which can seal the barrier sealing ring 322, provide a corresponding guide for the sliding of the barrier sealed bin 323, and reduce the possibility of air leakage. Moreover, due to the circulation of airflow in the barrier sealed bin 323, the air pressure in the barrier sealed bin 323 will rise, and even if a gap occurs, external air will not enter the barrier sealed bin 323, effectively reducing the entry of external moisture into the barrier sealed bin 323. The barrier sealed bin 323 is slidingly installed in the pair of barrier sealing rings 322, which can seal the barrier sealing ring 322 and provide a corresponding space for the circulation of air. The position of the barrier communication pipe 324 can be changed by rotating, which reduces the rotation of the centrifugal protection bin 21 and the probability of damage of the barrier communication pipe 324. The barrier communication pipe 324 is installed between the barrier air pump 321 and the barrier sealed bin 323, which can inject air into the barrier sealed bin 323 and provide help for the circulation of air.

[0042] As shown in Figures 1 to 6 The barrier air pump 321 penetrates the barrier guide ring 31 and is arranged in the barrier sealed bin 323, which can communicate the centrifugal protection bin 21 and the barrier sealed bin 323, improve the sealing between the centrifugal power driven wheel 232 and the barrier sealing ring 322, and reduce the probability of air leakage. The barrier communication pipe 324 penetrates the barrier sealed bin 323.

[0043] As shown in Figures 1 to 7 The dehumidification mechanism 4 includes a dehumidification water pump 41, a dehumidification guide plate 42 and a dehumidification communication pipe 43. The dehumidification water pump 41 is fixedly installed on the side of the barrier guide ring 31 away from the centrifugal protection bin 21, and can extract and discharge the moisture in the dehumidification guide plate 42. The dehumidification guide plate 42 is fixedly installed on the lower side of the motor body 1, can guide the moisture in the centrifugal protection bin 21, and can block the moisture in the centrifugal protection bin 21. The dehumidification communication pipe 43 is fixedly installed on the side of the dehumidification water pump 41 close to the barrier guide ring 31, and can communicate the dehumidification water pump 41 and the dehumidification guide plate 42.

[0044] As shown in Figures 1 to 7 The dehumidification communication pipe 43 is arranged through the dehumidification guide plate 42 and the blocking guide ring 31, the dehumidification guide plate 42 is provided with a plurality of evenly distributed liquid inlet grooves, which is convenient for absorbing the moisture in the centrifugal protection bin 21, and the dehumidification guide plate 42 is matched with the centrifugal protection bin 21, which is convenient for the dehumidification guide plate 42 to guide the moisture.
