Description

Technical Field

[0001] The present invention relates to the technical field of switched reluctance motors, and specifically to a switched reluctance motor capable of actively ventilating and cooling. Background Technique

[0002] The switched reluctance motor is a new type of speed-regulated motor. Its speed regulation system combines the advantages of DC and AC speed regulation systems. It is the latest generation of stepless speed regulation system after the variable frequency speed regulation system and the brushless DC motor speed regulation system. It has a simple and robust structure, a wide speed regulation range, excellent speed regulation performance, and high efficiency throughout the speed regulation range. The system has high reliability. The operation of the switched reluctance motor follows the "principle of minimum reluctance", that is, the magnetic flux always closes along the path with the minimum reluctance. When an iron core with a certain shape moves to the position of minimum reluctance, its main axis must coincide with the axis of the magnetic field. When the stator winding is energized, a magnetic field is generated. Due to the change in reluctance between the stator and rotor salient poles, the rotor will be subjected to a magnetic pulling force and rotate. Moreover, the rotation direction of the rotor is related to the energization sequence of the phase windings and has nothing to do with the current direction.

[0003] When the switched reluctance motor achieves high output power, it will cause the temperature of each part of the motor to rise, and it is necessary to cool it down. However, the existing cooling means usually improve the heat dissipation of the motor by modifying the motor housing, and it is difficult to actively cool it down. Therefore, we propose a switched reluctance motor capable of actively ventilating and cooling. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a switched reluctance motor capable of actively ventilating and cooling, including:

[0005] A motor housing, on one side of which a driving rod is provided;

[0006] An active ventilation and cooling device, which is used to actively guide the gas to be discharged from the motor interior and re-enter the motor interior to form a ventilation-type heat dissipation;

[0007] A blocking device, which is used to cover and block the exhaust holes that are not actively ventilated and cooled;

[0008] The inner wall of the motor housing is rotatably connected to one end of the driving rod through a rotating bolt. The inner wall of the motor housing is fixedly connected to the outer side of the active ventilation and cooling device. The outer side of the active ventilation and cooling device is connected to one end of the blocking device;

[0009] Among them, the active ventilation and cooling device includes:

[0010] A ventilation pipe, at one end of which a high-pressure air pump is provided;

[0011] Annular ventilation plate, which is set as an annular shell with an annular cavity inside. Small ventilation holes I are arranged on the inner side of the annular ventilation plate. By filling gas into the inner side of the annular ventilation plate and then discharging it through the exhaust round holes from the plugging device for ventilation heat dissipation, it can prevent the existing cooling means from usually improving the heat dissipation of the motor shell by transforming it, making it difficult to actively cool down.

[0012] One end of the ventilation pipe is communicated with the air outlet of the high-pressure air pump, and the other end of the ventilation pipe far from the high-pressure air pump is communicated with the outer side of the annular ventilation plate. There are multiple small ventilation holes I, and the multiple small ventilation holes I are distributed on the inner side of the annular ventilation plate.

[0013] The outer side of the annular ventilation plate is fixedly connected to the inner wall of the motor shell.

[0014] Heat dissipation arc holes are opened on the outer side of the motor shell. There are multiple heat dissipation arc holes, and the multiple heat dissipation arc holes are distributed on the outer side of the motor shell.

[0015] An auxiliary cleaning mechanism is sleeved and fixedly connected to the outer side of the high-pressure air pump. An exhaust round hole is opened at a position on the outer side of the annular ventilation plate far from the ventilation pipe. An internal partition plate is fixedly connected to the inner wall of the annular ventilation plate. By setting the internal partition plate in the annular ventilation plate, the inner part of the annular ventilation plate is divided into two areas to facilitate gas ventilation, preventing the gas from flowing back when it enters the area near the exhaust round hole in the annular ventilation plate again through the small ventilation holes I, which affects the heat dissipation efficiency. An arc-shaped baffle is fixedly connected to the inner wall of the annular ventilation plate. By setting the arc-shaped baffle on the inner wall of the annular ventilation plate to resist the gas sprayed by the high-pressure air pump, preventing the gas sprayed from the ventilation pipe from directly spraying out from a part of the small ventilation holes I on the opposite side and making it difficult to spray gas evenly. Small ventilation holes II are opened on the outer side of the arc-shaped baffle. By opening the small ventilation holes II staggered with the small ventilation holes I on the arc-shaped baffle, the gas can be evenly distributed around each small ventilation hole I and discharged evenly, preventing the gas from still pouring in from the local areas at the top and bottom when the gas is about to fill the area near the ventilation pipe in the annular ventilation plate and making it difficult to be evenly distributed around each small ventilation hole I.

[0016] One end of the auxiliary cleaning mechanism is fixedly connected to the outer side of the motor shell, and the outer side of the annular ventilation plate is communicated with one end of the plugging device through the exhaust round hole.

[0017] There are two internal partition plates, and the two internal partition plates are respectively distributed at the positions of the inner wall of the annular ventilation plate at the top and bottom. There are two arc-shaped baffles, and the two arc-shaped baffles are respectively distributed at the positions of the inner wall of the annular ventilation plate near the exhaust round hole and the ventilation pipe. There are multiple small ventilation holes II, and the multiple small ventilation holes II are distributed on the arc-shaped baffle and are staggered with the small ventilation holes I.

[0018] Furthermore, the auxiliary cleaning mechanism includes a dust filter plate and an arc-shaped fixed sleeve plate. A dust filter plate is arranged at the air inlet of the high-pressure air pump to filter the dust in the gas to be inhaled, preventing excessive dust in the gas inhaled into the motor from gradually accumulating inside the motor and affecting the use of the motor. A first fixed circular block is fixedly connected to the inner side of the arc-shaped fixed sleeve plate. The high-pressure air pump and the motor housing are fixedly connected through the arc-shaped fixed sleeve plate and the first fixed circular block for firm anti-vibration, preventing continuous vibration during the high-frequency operation of multiple high-pressure air pumps due to lack of firm fixation and affecting the use of the motor. A second fixed circular block is fixedly connected to the outer side of the arc-shaped fixed sleeve plate. One end of the second fixed circular block away from the arc-shaped fixed sleeve plate is fixedly connected to an annular electric slide rail. A square slider is rotatably connected to the inner wall of the annular electric slide rail. A strip-shaped scraping rod is fixedly connected to the side of the square slider close to the dust filter plate. When the strip-shaped scraping rod rotates, it scrapes the surface of the dust filter plate to prevent excessive dust particle impurities from gradually adsorbing on the surface of the dust filter plate after long-term use and blocking the dust filter holes, affecting the ventilation efficiency. Arc-shaped blocking rods are fixedly connected to both sides of the square slider. By arranging arc-shaped blocking rods that rotate together on both sides of the square slider to cover and block the chute of the annular electric slide rail, preventing a part of the dust particle impurities from gradually accumulating in the chute of the annular electric slide rail due to the chute of the annular electric slide rail being close to the gas flow area and affecting the use. The side of the dust filter plate away from the strip-shaped scraping rod is fixedly connected to one side of the high-pressure air pump. The arc-shaped fixed sleeve plate is sleeved on the high-pressure air pump and fixedly connected to the high-pressure air pump. One end of the first fixed circular block away from the arc-shaped fixed sleeve plate is fixedly connected to the outer side of the motor housing. The inner side of the annular electric slide rail is fixedly connected to the outer side of the high-pressure air pump. Multiple square sliders are provided, and the multiple square sliders are respectively distributed on the inner wall of the annular electric slide rail. Multiple arc-shaped blocking rods are provided, and the multiple arc-shaped blocking rods are respectively distributed on the inner wall of the annular electric slide rail.

[0019] Further, the plugging device includes an annular docking plate. An arc-shaped through hole is formed on the outer side of the annular docking plate. A strip-shaped stop bar is fixedly connected to a portion of the inner wall of the annular docking plate away from the arc-shaped through hole. By arranging the strip-shaped stop bar inside the annular docking plate, sliding limit is imposed on the circular baffle, preventing the circular baffle and the annular baffle from gradually moving to the outside of the annular docking plate under the influence of a large gas thrust and being prone to tilt and shift and being difficult to reset due to the elastic connection of the retraction spring. A cross-shaped ring plate is fixedly connected to a portion of the inner wall of the annular docking plate close to the arc-shaped through hole. A retraction spring is fixedly connected to one side of the cross-shaped ring plate. When the annular baffle is driven back by the retraction force of the retraction spring to contact the cross-shaped ring plate, the arc-shaped through hole is plugged, preventing external gas from freely flowing through the arc-shaped through hole and mixing with dust to enter the motor interior when the gas is not discharged to the outside and being difficult to handle. The end of the retraction spring away from the cross-shaped ring plate is fixedly connected to a circular baffle. An annular baffle is fixedly connected to one side of the circular baffle close to the retraction spring. When the annular baffle moves back, scraping cleaning is performed on the inner wall of the annular docking plate, preventing a part of the gas mixed with dust particles from seeping into the annular docking plate when the annular baffle reciprocates multiple times, resulting in a small amount of dust accumulating on the inner wall of the annular docking plate and being difficult to handle. By arranging an annular baffle whose inner wall is always in contact with the annular docking plate on one side of the circular baffle, sliding limit is imposed on the circular baffle, preventing the circular baffle elastically connected by the retraction spring from tilting and shifting due to uneven gas thrust and affecting gas discharge. One side of the annular docking plate is communicated with the outer side of the annular ventilation plate through an exhaust round hole. A plurality of arc-shaped through holes are provided, and the plurality of arc-shaped through holes are distributed on the outer side of the annular docking plate.

[0020] The present invention provides a switched reluctance motor capable of actively ventilating and cooling. It has the following beneficial effects:

[0021] 1. For the switched reluctance motor capable of actively ventilating and cooling, by filling gas into the inner side of the annular ventilation plate and then discharging it through the exhaust round hole from the plugging device for ventilation heat dissipation, it is prevented that the existing cooling means usually improve the heat dissipation of the motor by modifying the motor housing and it is difficult to perform active cooling. When the strip-shaped scraping rod rotates, scraping cleaning is performed on the surface of the dust filtering plate, preventing the dust filtering plate from gradually adsorbing too many dust particle impurities on its surface after long-term use and blocking the dust filtering holes and affecting the ventilation efficiency. When the annular baffle is driven back by the retraction force of the retraction spring to contact the cross-shaped ring plate, the arc-shaped through hole is plugged, preventing external gas from freely flowing through the arc-shaped through hole and mixing with dust to enter the motor interior when the gas is not discharged to the outside and being difficult to handle.

[0022] 2. The switched reluctance motor capable of active ventilation cooling is provided with an active ventilation cooling device. By arranging arc-shaped baffles on the inner wall of the annular ventilation plate, the gas injected by the high-pressure air pump is blocked, preventing the gas injected from the ventilation pipe from directly spraying out from a part of the small ventilation holes I on the opposite side and making it difficult to spray the gas evenly. By opening small ventilation holes II staggered from the small ventilation holes I on the arc-shaped baffle, the gas can be evenly distributed around each small ventilation hole I and discharged evenly, preventing the gas from still being poured in from the local areas at the top and bottom when the annular ventilation plate is about to be filled with gas in the area near the ventilation pipe and making it difficult to be evenly distributed around each small ventilation hole I. By arranging an internal partition plate in the annular ventilation plate, the inner part of the annular ventilation plate is divided into two areas to facilitate gas replacement, preventing the gas from flowing back when passing through the small ventilation holes I again and entering the area near the exhaust round hole inside the annular ventilation plate, which affects the heat dissipation efficiency. By filling the gas into the inner side of the annular ventilation plate and then discharging it through the exhaust round hole from the sealing device for replacement heat dissipation, it is prevented that the existing cooling means usually improve the heat dissipation of the motor by modifying the motor housing and it is difficult to perform active cooling and temperature reduction on it.

[0023] 3. The switched reluctance motor capable of active ventilation cooling is provided with an auxiliary cleaning mechanism. By arranging a dust filter plate at the air inlet of the high-pressure air pump, the dust in the gas to be inhaled is filtered, preventing the gas inhaled into the motor interior from being mixed with too much dust and gradually accumulating inside the motor, which affects the use of the motor. The high-pressure air pump and the motor housing are fixedly connected and stabilized against vibration through an arc-shaped fixed sleeve plate and a fixed round block I, preventing the high-frequency operation of multiple high-pressure air pumps from not being tightly fixed and continuously vibrating, which affects the use of the motor. When the strip-shaped scraping rod rotates, it scrapes the surface of the dust filter plate, preventing the surface of the dust filter plate from gradually adsorbing too many dust particle impurities after long-term use and blocking the dust filter holes, which affects the ventilation efficiency. By arranging arc-shaped blocking rods that rotate together on both sides of the square slider, the chute of the annular electric slide rail is covered and blocked, preventing the chute of the annular electric slide rail from being close to the gas flow area and causing some dust particle impurities to gradually accumulate in the chute of the annular electric slide rail, which affects the use.

[0024] 4. The switched reluctance motor capable of active ventilation cooling is provided with a plugging device. By arranging strip-shaped blocking rods inside the annular docking plate, sliding limit is imposed on the circular baffle to prevent the circular baffle and the annular baffle from gradually moving to the outside of the annular docking plate when the gas thrust is large and being prone to tilt and shift and being difficult to reset under the influence of the elastic connection of the retraction spring. When the annular baffle is driven back by the retraction force of the retraction spring and contacts the cross-shaped ring plate, the arc-shaped through hole is plugged to prevent external gas from freely flowing through the arc-shaped through hole and mixing with dust and entering the motor interior when the gas is not discharged to the outside, which is difficult to handle. When the annular baffle moves back, it scrapes and cleans the inner wall of the annular docking plate to prevent a part of the gas mixed with dust particles from seeping into the annular docking plate when the annular baffle reciprocates multiple times, resulting in a small amount of dust accumulating on the inner wall of the annular docking plate, which is difficult to handle. By arranging an annular baffle on one side of the circular baffle whose inner wall is always in contact with the annular docking plate, sliding limit is imposed on the circular baffle to prevent the circular baffle elastically connected by the retraction spring from tilting and shifting when the gas thrust is uneven, affecting gas discharge.

There are multiple square sliders 3056, and the multiple square sliders 3056 are respectively distributed on the inner wall of the annular electric slide rail 3055. There are multiple arc-shaped blocking rods 3058, and the multiple arc-shaped blocking rods 3058 are respectively distributed on the inner wall of the annular electric slide rail 3055. During use, the active ventilation and cooling device 3 fills the motor with gas and pushes the gas inside the motor out from the plugging device 4 on the other side, so that the inside of the motor continuously conducts ventilation-type heat dissipation and cooling. The high-pressure air pump 302 inhales external gas into the ventilation pipe 301 and enters an area separated by the built-in partition plate 307 in the annular ventilation plate 303. The gas ejected from the ventilation pipe 301 contacts the arc-shaped baffle 308 and diffuses around along the arc surface of the arc-shaped baffle 308. By arranging the arc-shaped baffle 308 on the inner wall of the annular ventilation plate 303 to resist the gas injected by the high-pressure air pump 302, when the gas flows along the arc surface of the arc-shaped baffle 308, it will sequentially pass through the second small ventilation holes 309 and contact the inner wall of the annular ventilation plate 303. By arranging the second small ventilation holes 309 on the arc-shaped baffle 308 that are staggered from the first small ventilation holes 304, the gas can be evenly distributed around each first small ventilation hole 304 and evenly discharged. Until the gas fills the arc-shaped area near the ventilation pipe 301 inside the annular ventilation plate 303, it will be discharged to the inner side of the annular ventilation plate 303 through the first small ventilation holes 304. When the gas gradually enters the inner side area of the annular ventilation plate 303, it will push the original gas to pass through the first small ventilation holes 304 near the exhaust round hole 306 and enter the area inside the annular ventilation plate 303 near the exhaust round hole 306. At this time, the gas entering the area inside the annular ventilation plate 303 near the exhaust round hole 306 will contact the arc-shaped baffle 308 and gradually fill this area and then be discharged to the outside through the exhaust round hole 306. By arranging the built-in partition plate 307 inside the annular ventilation plate 303, the inside of the annular ventilation plate 303 is divided into two areas to facilitate gas replacement.Ventilation and heat dissipation are carried out by filling gas into the inner side of the annular ventilation plate 303 and then discharging it from the exhaust round holes 306 through the sealing device 4.

At the same time, the annular electric slide rail 3055 drives the square slider 3056 to drive the strip-shaped scraping rod 3057 and the arc-shaped blocking rods 3058 on both sides to rotate together. When the strip-shaped scraping rod 3057 rotates, the surface of the dust filter plate 3051 is cleaned by scraping.

[0049] Please refer to Figures 1-8 , the present invention provides a switched reluctance motor capable of actively ventilating and cooling: the sealing device 4 includes an annular docking plate 401, an arc-shaped through hole 402 is formed on the outer side of the annular docking plate 401, a strip-shaped blocking rod 403 is fixedly connected to a portion of the inner wall of the annular docking plate 401 far from the arc-shaped through hole 402, a cross-shaped ring plate 404 is fixedly connected to a portion of the inner wall of the annular docking plate 401 close to the arc-shaped through hole 402, a retraction spring 405 is fixedly connected to one side of the cross-shaped ring plate 404, a circular baffle 406 is fixedly connected to an end of the retraction spring 405 far from the cross-shaped ring plate 404, an annular baffle 407 is fixedly connected to a side of the circular baffle 406 close to the retraction spring 405, one side of the annular docking plate 401 is communicated with the outer side of the annular ventilation plate 303 through the exhaust round hole 306, a plurality of arc-shaped through holes 402 are provided, and the plurality of arc-shaped through holes 402 are distributed on the outer side of the annular docking plate 401. During use, after the gas is discharged from the exhaust round hole 306, it enters the annular docking plate 401. When the gas gradually fills the inside of the annular docking plate 401, it pushes the circular baffle 406 to drive the annular baffle 407 to move together in the direction of the strip-shaped blocking rod 403. When the annular baffle 407 gradually moves in the direction of the strip-shaped blocking rod, it disengages from the covering and blocking of the arc-shaped through hole 402. At this time, the gas inside the annular docking plate 401 can be discharged to the outside through the arc-shaped through hole 402. The strip-shaped blocking rod 403 is arranged inside the annular docking plate 401 to slide and limit the circular baffle 406. When the motor is not actively ventilated and cooled, the circular baffle 406 loses the push of the gas. At this time, the retraction spring 405 drives the circular baffle 406 to move back through the retraction force. When the circular baffle 406 moves back, it drives the annular baffle 407 on one side to move back together. When the annular baffle 407 moves back to contact the cross-shaped ring plate 404 through the retraction force of the retraction spring 405, the arc-shaped through hole 402 is blocked. When the annular baffle 407 moves back, it scrapes and cleans the inner wall of the annular docking plate 401. The annular baffle 407 whose inner wall is always in contact with the annular docking plate 401 is arranged on one side of the circular baffle 406 to slide and limit the circular baffle 406.

[0049]

[0050] When the present invention is in operation, gas is filled into the motor through the active ventilation and cooling device 3 and the gas inside the motor is pushed out from the plugging device 4 on the other side, so that the inside of the motor continuously conducts ventilation-type heat dissipation and cooling. The external gas is inhaled into the ventilation pipe 301 by the high-pressure air pump 302 and enters an area separated by the built-in partition plate 307 in the annular ventilation plate 303. The gas ejected from the ventilation pipe 301 contacts the arc-shaped baffle 308 and diffuses around along the arc surface of the arc-shaped baffle 308. By arranging the arc-shaped baffle 308 on the inner wall of the annular ventilation plate 303 to resist the gas injected by the high-pressure air pump 302, when the gas flows along the arc surface of the arc-shaped baffle 308, it will sequentially pass through the small ventilation holes II 309 and contact the inner wall of the annular ventilation plate 303. By arranging the small ventilation holes II 309 on the arc-shaped baffle 308 that are staggered from the small ventilation holes I 304, the gas can be evenly distributed around each small ventilation hole I 304 and evenly discharged. Until the gas fills the arc-shaped area near the ventilation pipe 301 inside the annular ventilation plate 303, it will be discharged to the inner side of the annular ventilation plate 303 through the small ventilation holes I 304. When the gas gradually enters the inner side area of the annular ventilation plate 303, it will push the original gas to pass through the small ventilation holes I 304 near the exhaust round hole 306 and enter the area inside the annular ventilation plate 303 near the exhaust round hole 306. At this time, the gas entering the area inside the annular ventilation plate 303 near the exhaust round hole 306 will contact the arc-shaped baffle 308 and gradually fill this area and then be discharged to the outside through the exhaust round hole 306 into the plugging device 4. By arranging the built-in partition plate 307 inside the annular ventilation plate 303, the inside of the annular ventilation plate 303 is divided into two areas to facilitate gas ventilation. By filling the gas into the inner side of the annular ventilation plate 303 and then passing through the exhaust round hole 306 to be discharged from the plugging device 4 for ventilation-type heat dissipation. By arranging the dust filter plate 3051 at the air inlet of the high-pressure air pump 302 to filter the dust of the gas to be inhaled. The high-pressure air pump 302 and the motor housing 1 are fixedly connected through the arc-shaped fixing sleeve plate 3052 and the fixing round block I 3053 for firm anti-vibration. At the same time, the square slider 3056 is driven by the annular electric slide rail 3055 to drive the strip-shaped scraping rod 3057 and the arc-shaped blocking rods 3058 on both sides to rotate together. When the strip-shaped scraping rod 3057 rotates, it scrapes and cleans the surface of the dust filter plate 3051. By arranging the arc-shaped blocking rods 3058 that rotate together on both sides of the square slider 3056 to cover and block the sliding groove of the annular electric slide rail 3055. After the gas is discharged from the exhaust round hole 306, it enters the annular docking plate 401. When the gas gradually fills the inside of the annular docking plate 401, it pushes the circular baffle 406 to drive the annular baffle 407 to move together towards the strip-shaped blocking rod 403 direction. When the annular baffle 407 gradually moves towards the strip-shaped blocking rod direction, it disengages from the covering and blocking of the arc-shaped through hole 402. At this time, the gas inside the annular docking plate 401 can be discharged to the outside through the arc-shaped through hole 402.The circular baffle 406 is slidably limited by arranging a strip-shaped stop rod 403 inside the annular docking plate 401. When the circular baffle 406 loses the push of gas when the motor is not actively ventilated and cooled, the retraction spring 405 drives the circular baffle 406 to move back through the retraction force. When the circular baffle 406 moves back, it drives the annular baffle 407 on one side to move back together. When the annular baffle 407 is driven by the retraction force of the retraction spring 405 to move back and contact the cross-ring plate 404, the arc-shaped through hole 402 is blocked. When the annular baffle 407 moves back, it scrapes and cleans the inner wall of the annular docking plate 401. The circular baffle 406 is slidably limited by arranging an annular baffle 407 on one side of the circular baffle 406 whose inner wall is always in contact with the annular docking plate 401.,
