Description

Technical Field

[0001] This invention belongs to the field of motor equipment technology, and in particular relates to an energy-saving high-voltage motor air circuit. Background Technology

[0002] During operation, high-voltage motors generate a large amount of heat due to various electrical and magnetic losses. If this heat cannot be dissipated in time, the temperature of the motor's internal structure will continue to rise, affecting the motor's performance and lifespan, and may even cause overheating and burnout, as well as equipment failure. The energy-saving high-voltage motor airflow path is the flow path and channel for cooling air inside the high-voltage motor, designed to effectively dissipate heat and ensure stable motor operation.

[0003] Existing motor ventilation systems typically involve creating heat dissipation holes in the motor housing and optimizing the ventilation gap between the stator and rotor. However, the presence of these holes allows dust and impurities from the air to enter the housing, affecting the stable operation of the drive components. Although some motors have filters installed at the heat dissipation holes, these filters are prone to clogging over time due to their limited ventilation area, thus impacting the motor's heat dissipation performance.

[0004] Therefore, it is necessary to invent an energy-saving high-voltage motor air circuit to solve the above problems. Summary of the Invention

[0008] Furthermore, the mounting slot is equipped with a sealing assembly for sealing or opening the air inlet and exhaust ports. The sealing assembly includes a cover plate, a sealing plate, a pull rod, a U-shaped clamping plate, and a power mechanism. The cover plate is detachably installed at the opening of the mounting groove, and the cover plate is located between the air inlet and the exhaust port. There are two sealing plates, which are respectively aligned with the air inlet and the exhaust port. The pull rod is vertically fixedly connected to the side of the sealing plate near the cover plate. The U-shaped clamp is slidably engaged with the pull rod, and the U-shaped clamp is fixedly connected to the inner wall of the mounting groove.

[0009] Furthermore, the power mechanism includes a drive component, a drive shaft, and gears; The drive shaft is located at the symmetrical center of the two sealing plates, and the drive shaft is vertically rotated and inserted through the cover plate. The drive component is connected to the end of the drive shaft away from the housing. The gear is fixedly sleeved on the end of the drive shaft away from the drive component. The two pull rods are distributed vertically and are rotationally symmetrical about the gear. The pull rods and the gear are provided with teeth at the positions directly opposite each other, and the teeth are always meshed with the gear.

[0010] Furthermore, the cleaning assembly includes a brush plate, brush bristles, and a baffle. The ash discharge hole is opened through the bottom of the air inlet on the side of the housing, and the bottom inner walls of the ash discharge hole, air inlet, and exhaust hole all gradually slope downward away from the housing. The brush plate is hinged to the top inner wall of the ash discharge hole by a torsion spring. The bristles are evenly distributed on the side of the brush plate near the annular filter screen, and the bristles can always be in contact with the annular filter screen under the action of the torsion spring. The baffle is hinged at the opening of the ash discharge hole, and the bottom end of the baffle can only deflect away from the brush plate.

[0011] Furthermore, an air guide hole is provided through the arc-shaped protective plate at the position directly opposite the ash discharge hole, and an air guide cover is fixedly connected to the inner side of the arc-shaped protective plate at the position directly opposite the air guide hole. The air guide cover is located on the side of the mounting ring close to the second heat dissipation fan, and the opening of the air guide cover is directly opposite to the direction of the first heat dissipation fan.

[0012] Furthermore, a heat dissipation plate matching the length of the support bar is provided between two adjacent support bars.

Several strip-shaped heat dissipation grooves are opened along the axial direction of the housing on the side of the heat dissipation plate that is directly opposite to the stator, and the two ends of the heat dissipation grooves are connected to the two ends of the heat dissipation plate.

[0013] Furthermore, the first and second cooling fans have the same diameter, and both the first and second cooling fans can generate airflow towards the exhaust port as the shaft rotates.

[0014] Furthermore, a protective cover is fitted onto the outer side of the drive component, and the protective cover is detachably connected to the cover plate.

[0015] Furthermore, the brush plate is hollow and filled with desiccant. A strip-shaped drying hole is provided on the top surface of the brush plate.

A shock-absorbing spring is sleeved on the telescopic rod, and the rubber roller is able to remain in close contact with the annular filter screen under the action of the shock-absorbing spring.

[0016] The technical effects and advantages of this invention are as follows: 1. The present invention features a rotating annular filter screen. During the rotation of the mounting ring driven by the rotating shaft, the first magnetic block on the mounting ring can generate a magnetic pull on the second magnetic block on the annular filter screen, thereby enabling the annular filter screen to rotate within the annular groove. This allows the position of the annular filter screen facing the air inlet to continuously change, enabling the annular filter screen to filter the air entering the housing more evenly. Compared with the filter screen fixed on the existing motor, this reduces the probability of the annular filter screen being clogged. 2. The present invention is equipped with bristles. During the rotation of the annular filter screen, the brush plate can adhere the bristles to the annular filter screen under the action of the torsion spring. As the annular filter screen rotates, the bristles can brush along the outer side of the annular filter screen, thereby brushing the dust attached to the annular filter screen off the annular filter screen and into the dust discharge hole, avoiding the annular filter screen from being blocked by dust and impurities and ensuring the filtration effect of the annular filter screen. 3. By incorporating a sealing component, when the motor finishes operating, the drive component can drive the gear to rotate in the opposite direction via the drive shaft. This allows the two pull rods to push the two sealing plates in a disjointed direction under the action of the gear, thereby blocking the air inlet and outlet. This prevents dust and impurities in the outside air from adhering to the filter plate and the annular filter screen when the motor is not in use. It also blocks moisture in the air, reducing the probability of moisture entering the housing. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides, for example Figures 1 to 10 The diagram illustrates an energy-saving high-voltage motor airflow system, comprising a housing 1, a stator 2 disposed inside the housing 1, and several support bars 3 evenly distributed axially on the outer side of the stator 2, the support bars 3 being fixedly connected to the inner wall of the housing 1. A rotor 4 is disposed inside the stator 2, and a rotating shaft 5 is inserted through both ends of the rotor 4. Sealing covers 6 are fitted near both ends of the rotating shaft 5, and the two sealing covers 6 are detachably connected to both ends of the housing 1. A first cooling fan 7 and a second cooling fan 8 are respectively fitted onto the inner surfaces of the rotating shaft 5 at both ends of the housing 1. A mounting groove is provided on the side of the housing 1, connecting the housing 1 to the first cooling fan 7 and the second cooling fan 8. The two cooling fans 8 have vertical air inlets and exhaust outlets respectively, with a filter plate 9 installed at the exhaust outlet to block dust and impurities in the outside air and prevent them from entering the inside of the housing 1 through the exhaust outlet. The first cooling fan 7 has a filter device on the side close to the second cooling fan 8. The filter device includes an annular filter screen 10, an arc-shaped protective plate 11, and a drive assembly. The first cooling fan 7 and the second cooling fan 8 have the same diameter, and both the first cooling fan 7 and the second cooling fan 8 can blow the air inside the housing 1 to the outside of the housing 1 through the exhaust outlet as the rotating shaft 5 rotates. An annular groove 12 is provided on the side wall of the housing 1. The annular filter screen 10 is rotatably installed in the annular groove 12. The arc-shaped protective plate 11 is coaxial with the annular filter screen 10, and the two ends of the arc-shaped protective plate 11 are respectively aligned with the inner wall of the top and bottom of the air inlet. The outer side of the arc-shaped protective plate 11 is provided with a groove matching its length. The arc-shaped protective plate 11 is fixedly connected to the inner wall of the housing 1, and the annular filter screen 10 is located in the groove. The driving component is set in the inner area of ​​the arc-shaped protective plate 11 and is used to drive the annular filter screen 10 to rotate when the rotating shaft 5 rotates. A dust discharge hole 25 is provided on the side wall of the housing 1. A cleaning component for cleaning the annular filter screen 10 is provided in the dust discharge hole 25. The drive assembly includes a fixed ring 13, a mounting ring 14, a connecting rod 15, a first magnetic block 16, and a second magnetic block 17. The fixed ring 13 is detachably sleeved on the rotating shaft 5, and the mounting ring 14 is sleeved on the periphery of the fixed ring 13, and the two are coaxial. There are multiple connecting rods 15, which are evenly fixedly connected between the fixed ring 13 and the mounting ring 14. There are the same number of first magnetic blocks 16 and second magnetic blocks 17, and multiple first magnetic blocks 16 are evenly fixedly connected on the outer surface of the mounting ring 14, and multiple second magnetic blocks 17 are evenly fixedly connected on the inner surface of the annular filter screen 10, and the magnetic poles of the first magnetic blocks 16 and the second magnetic blocks 17 on the opposite side are opposite. During the operation of the motor, as the rotating shaft 5 drives the rotor 4 to rotate inside the stator 2, the first cooling fan 7 and the second cooling fan 8 can rotate together with the rotating shaft 5. At this time, the first cooling fan 7 and the second cooling fan 8 can generate wind towards the exhaust port. At the same time, outside air can continuously enter the housing 1 through the air inlet under the siphon effect and blow onto the stator 2 and rotor 4 under the action of the first cooling fan 7, thereby directly cooling the stator 2 and rotor 4. Due to the presence of the support bars 3, when the air generated by the first cooling fan 7 blows onto the stator 2 and rotor 4, the air can flow through the gap between two adjacent support bars 3 to the area where the second cooling fan 8 is located. When the air carrying heat moves to the area where the second cooling fan 8 is located, as the second cooling fan 8 rotates, the second cooling fan 8 can discharge the air carrying heat through the exhaust port to the housing 1, thereby realizing the rapid discharge of heat from the housing 1. In addition, during the rotation of the second cooling fan 8, in addition to being able to discharge the hot air gathered near it through the exhaust port to the housing 1, since the second cooling fan 8 and the first cooling fan 7 generate air in the same direction, the side of the second cooling fan 8 close to the first cooling fan 7 can generate suction on the area where the rotor 4 and stator 2 are located, thereby accelerating the speed of the air generated by the first cooling fan 7 through the gap between two adjacent support bars 3, thereby improving the heat dissipation effect of the first cooling fan 7 on the rotor 4 and stator 2. In addition, since the annular filter 10 is rotatably installed in the annular groove 12, as the rotating shaft 5 drives the mounting ring 14 to rotate through the fixed ring 13 and the connecting rod 15, the multiple first magnetic blocks 16 on the mounting ring 14 can move in annular motion with the mounting ring 14. During this process, the first magnetic blocks 16 on the mounting ring 14 can generate magnetic pull on the second magnetic blocks 17 on the annular filter 10, thereby enabling the annular filter 10 to rotate in the annular groove 12. This allows the position of the annular filter 10 facing the air inlet to change continuously, so that the annular filter 10 can filter the air entering the housing 1 more evenly. This reduces the probability of the annular filter 10 being blocked compared to the filter fixed on the existing motor. During the process of the annular filter 10 filtering the air entering the housing 1, the cleaning component can clean the annular filter 10 and discharge the cleaned dust and impurities into the housing 1 through the dust discharge hole 25. This effectively prevents the annular filter 10 from being blocked by dust and impurities, ensuring the filtration effect of the annular filter 10. In addition, due to the presence of the arc-shaped protective plate 11, during the cleaning process of the annular filter 10, the arc-shaped protective plate 11 can isolate the remaining part of the annular filter 10 that is not directly opposite the air inlet, preventing the cleaned dust from directly entering the inner area of ​​the housing 1 as the annular filter 10 rotates.

[0021] like Figures 1 to 3 As shown, a sealing assembly for closing or opening the air inlet and exhaust port is installed in the mounting slot. The sealing assembly includes a cover plate 18, a sealing plate 19, a pull rod 20, a U-shaped clamping plate 21, and a power mechanism. The cover plate 18 is detachably installed at the opening of the mounting slot and is located between the air inlet and exhaust port. There are two sealing plates 19, which are respectively aligned with the air inlet and exhaust port. The pull rod 20 is vertically fixedly connected to the side of the sealing plate 19 near the cover plate 18. The U-shaped clamping plate 21 is slidably engaged with the pull rod 20 and is fixedly connected to the inner wall of the mounting slot. The power mechanism includes a drive component 22, a drive shaft 23, and a gear 24. The drive shaft 23 is located at the symmetrical center of the two sealing plates 19, and the drive shaft 23 is vertically rotatably inserted into the cover plate 18. The drive component 22 can be a motor. The drive component 22 is connected to the end of the drive shaft 23 away from the housing 1. The gear 24 is fixedly sleeved on the end of the drive shaft 23 away from the drive component 22. The two pull rods 20 are distributed vertically and are rotationally symmetrical about the gear 24. The pull rods 20 and the gear 24 are provided with teeth at the positions directly opposite each other, and the teeth are always meshed with the gear 24. A protective cover 31 is sleeved on the outside of the drive component 22. The protective cover 31 is detachably connected to the cover plate 18 to protect the drive component 22. By incorporating a closed assembly, the drive unit 22 can be activated when the motor is running, thereby driving the gear 24 to rotate via the drive shaft 23. As the gear 24 rotates, the two pull rods 20, under the action of the gear 24, pull the two sealing plates 19 to move closer to each other, thus gradually opening the air inlet and outlet, facilitating the exchange and flow of outside air with the air inside the housing 1. When the motor finishes running, the drive unit 22 can drive the gear 24 to rotate in the opposite direction via the drive shaft 23. As the gear 24 rotates in the opposite direction, the two pull rods 20, under the action of the gear 24, push the two sealing plates 19 to move away from each other, thereby blocking the air inlet and outlet. This prevents dust and impurities in the outside air from adhering to the filter plate 9 and the annular filter screen 10 when the motor is not in use, and also blocks moisture in the air, reducing the probability of moisture entering the housing 1.

[0022] like Figure 6 As shown, the cleaning assembly includes a brush plate 26, bristles 27, and a baffle 28; the dust discharge hole 25 is opened through the bottom of the air inlet on the side of the housing 1, and the bottom inner walls of the dust discharge hole 25, the air inlet, and the exhaust hole are all gradually inclined downwards away from the housing 1. The brush plate 26 is hinged to the top inner wall of the dust discharge hole 25 by a torsion spring. The bristles 27 are evenly arranged on the side of the brush plate 26 near the annular filter screen 10, and the bristles 27 can always be in contact with the annular filter screen 10 under the action of the torsion spring. The baffle 28 is hinged to the opening of the dust discharge hole 25, and the bottom end of the baffle 28 can only deflect away from the brush plate 26. With the brush bristles 27 provided, as the annular filter screen 10 rotates, the brush plate 26 can adhere the brush bristles 27 to the annular filter screen 10 under the action of the torsion spring. Thus, as the annular filter screen 10 rotates, the brush bristles 27 can brush along the outer side of the annular filter screen 10, thereby brushing the dust attached to the annular filter screen 10 off the annular filter screen 10 and into the dust discharge hole 25, preventing the annular filter screen 10 from being blocked by dust and impurities and ensuring the filtration effect of the annular filter screen 10. After the annular filter 10 has been used for a period of time, the baffle 28 can be pulled, causing the bottom of the baffle 28 to deflect away from the housing 1, thereby opening the dust discharge hole 25. Then, the dust in the dust discharge hole 25 can be swept out along the inclined bottom inner wall of the dust discharge hole 25. After cleaning, the baffle 28 can be released, and the baffle 28 can automatically block the opening of the dust discharge hole 25 under the action of gravity, thereby preventing external debris and some insects from entering the dust discharge hole 25.

[0023] like Figures 7 to 9As shown, an air guide hole is provided through the arc-shaped protective plate 11 at the position directly opposite to the ash discharge hole 25. An air guide cover 29 is fixedly connected to the inner side of the arc-shaped protective plate 11 at the position directly opposite to the air guide hole. The air guide cover 29 is located on the side of the mounting ring 14 close to the second cooling fan 8. The opening of the air guide cover 29 is directly opposite to the direction of the first cooling fan 7. By providing an air guide shroud 29, when the air generated by the first cooling fan 7 blows onto the air guide shroud 29, the air guide shroud 29 can blow the air through the air guide holes onto the position where the annular filter 10 and the dust discharge hole 25 are directly opposite each other. This, together with the brush bristles 27, makes it easier to blow the dust attached to the annular filter 10 out through the dust discharge hole 25, thereby improving the cleaning effect of the brush bristles 27 on the annular filter 10. In addition, when the wind blows onto the baffle 28 through the ash discharge hole 25, the bottom of the baffle 28 can be deflected away from the housing 1 under the action of the wind force, so that the ash discharge hole 25 is automatically opened, making it easier for the dust in the ash discharge hole 25 to be removed from the ash discharge hole 25.

[0024] like Figure 5 As shown, a heat dissipation plate 30 matching the length of the support bar 3 is provided between two adjacent support bars 3. The heat dissipation plate 30 has a hollow design and is filled with coolant. Several strip-shaped heat dissipation grooves are opened along the axial direction of the housing 1 on the side of the heat dissipation plate 30 that is directly opposite to the stator 2, and the two ends of the heat dissipation grooves are connected to the two ends of the heat dissipation plate 30. By providing a heat dissipation plate 30, the heat generated by the rotor 4 and stator 2 during motor operation can be absorbed by the heat dissipation plate 30 and its internal coolant, thereby improving the heat dissipation effect of the motor in conjunction with the heat dissipation effect of the first cooling fan 7 and the second cooling fan 8 on the rotor 4 and stator 2. As the air generated by the first cooling fan 7 flows through the heat dissipation groove of the heat dissipation plate 30, the heat dissipation groove not only provides a flow path for the air inside the housing 1, but also increases the contact area between the heat dissipation plate 30 and the air generated by the first cooling fan 7. This allows the air generated by the first cooling fan 7 to quickly dissipate the heat absorbed by the heat dissipation plate 30 and its internal coolant through the heat dissipation groove, ensuring the heat dissipation effect of the heat dissipation plate 30 and its internal coolant on the motor.

[0025] like Figure 6 and Figure 10As shown, the brush plate 26 is hollow and filled with desiccant. The top surface of the brush plate 26 has strip-shaped drying holes 32. A guide plate 33 is slidably installed on the top of the brush plate 26. The side of the guide plate 33 closest to the annular filter screen 10 is curved upwards, and a rubber roller 34 is installed at the edge of the curved edge of the guide plate 33. Two telescopic rods 35 are symmetrically fixedly connected to the side of the guide plate 33 away from the annular filter screen 10. The end of the telescopic rod 35 away from the guide plate 33 is fixedly connected to the top of the brush plate 26. A shock-absorbing spring 36 is sleeved on the telescopic rod 35, and the rubber roller 34 can always be in contact with the annular filter screen 10 under the action of the shock-absorbing spring 36. By providing a desiccant inside the brush plate 26, when the invention is not in use, the desiccant inside the brush plate 26 can dry the air entering the ash discharge hole 25, thus preventing moisture from the ground and the air from entering the housing 1 through the ash discharge hole 25 because the ash discharge hole 25 is too close to the ground. Furthermore, by providing a rubber roller 34, during the rotation of the annular filter screen 10, the rubber roller 34 can remain in contact with the annular filter screen 10 under the action of the damping spring 36 and rotate together with the annular filter screen 10, thereby providing a pressing effect on the annular filter screen 10. When the annular filter screen 10 vibrates during rotation, the rubber roller 34 can transmit the vibration generated by the annular filter screen 10 to the damping spring 36, so that the damping spring 36 can adaptively extend and retract, thereby converting the vibration generated by the annular filter screen 10 into the elastic potential energy of the damping spring 36. This ensures the stable rotation of the annular filter screen 10 while reducing the noise generated when the annular filter screen 10 rotates. In addition, by providing the guide plate 33, during the operation of this invention, when the air generated by the first cooling fan 7 blows into the ash discharge hole 25, the air can carry some of the heat inside the housing 1 and blow it onto the guide plate 33. Then the guide plate 33 can introduce the hot air into the brush plate 26 through the drying hole 32, thereby using the heat to heat the desiccant inside the brush plate 26. Subsequently, the water vapor in the desiccant can be discharged through the ash discharge hole 25, thereby ensuring the dryness of the desiccant and improving the drying effect of the desiccant on the air entering the housing 1 when this invention is not in use.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
