Description

Technical Field

[0001] The present invention relates to the technical field of motor insulation, and specifically to an insulation structure for high-voltage motors. Background Art

[0002] A high-voltage motor refers to a motor with a rated voltage above one thousand volts. It has the advantages of large power and strong impact resistance. When the starting and braking coils of a high-voltage motor cut the magnetic field, a strong current will be generated, which is likely to break through the insulation layer outside the wire, causing the motor casing to be electrified.

[0003] For example, an insulation structure of a high-speed motor with the publication number CN215267927U includes a housing. The bottom inner wall of the housing is slidably connected with two fastening plates. A high-speed motor is clamped and connected between the two fastening plates. The output end of the high-speed motor is provided with a motor rotor shaft, and the motor rotor shaft penetrates and connects with one side of the housing. One side of the inner arc of the fastening plate is provided with a spring column, and one end of the spring column close to the high-speed motor is connected with an insulation anti-collision pad. By setting a protection and shock-absorption structure outside the high-speed motor, the loss of the high-speed motor is reduced and the service life is improved. However, the device seals and protects the motor through the housing, which is not convenient for the heat generated by the motor during operation to be discharged in time. When the temperature inside the motor is too high, it will cause the insulation material to age, thereby reducing the insulation performance of the high-voltage motor, and further affecting the safety of the motor. Moreover, when the motor operates in a humid environment, the moisture in the air will also reduce the insulation performance, and even cause the motor winding to crack, discolor or peel off.

[0004] Therefore, an insulation structure for high-voltage motors is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an insulation structure for high-voltage motors to solve the problem that the motor is sealed and protected by the housing, which is not convenient for the heat generated by the motor during operation to be discharged in time, and may cause the insulation material to age and reduce the insulation performance of the high-voltage motor.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An insulation structure for high-voltage motors includes an insulation housing, a high-voltage motor main body, and a base fixedly installed at the bottom of the insulation housing through bolts. An insulation sleeve ring is fixedly installed at the lower part of one side of the insulation housing.

[0007] It further includes:

[0008] An insulation protection component is arranged in the middle of the insulation housing, and a ventilation component is arranged above the insulation housing.

[0009] The insulation protection assembly includes a moving unit and a rotating unit. The moving unit includes a moving seat that can linearly slide on the top of the insulation shell. A pulling rope is fixedly connected to the bottom of the moving seat. The pulling rope passes through the insulation shell and is connected to a sliding plate. A fixing ring is fixedly connected to the bottom of the sliding plate. A rotating ring is rotatably installed on one side of the fixing ring.

[0010] The rotating unit includes fixing plates symmetrically and fixedly installed on both sides of the inner bottom surface of the base. An electric motor part is fixedly installed outside the left fixing plate. The output end of the electric motor part passes through the left fixing plate and is fixedly connected to a fixing rod. A sleeve is slidably installed on the outer side of the fixing rod, and the sleeve can slide on the outer side of the fixing rod. A first gear ring is fixedly connected to the outer side of the rotating ring. A second gear ring is fixedly connected to the outer side of the sleeve. The first gear ring is meshed and connected with the second gear ring.

[0011] Preferably, a linear motor and a sliding table are fixedly installed on the top of the insulation shell. The linear motor drives the moving seat to slide outside the sliding table. A guiding roller is fixedly installed on one side of the inner top surface of the insulation shell. One end of the pulling rope away from the moving seat bypasses the guiding roller and is fixedly connected to the sliding plate. The pulling rope is slidably connected with the insulation shell. A guiding groove is formed in the middle of the inner top surface of the insulation shell. The sliding plate is slidably connected with the guiding groove.

[0012] By adopting the above technical solution, through the extrusion and scraping of the arc-shaped plate in cooperation with the movement and self-rotation scraping of the rotating ring, the obstruction of dust and the like to the heat dissipation of the high-voltage motor main body is reduced, and the overheating of the high-voltage motor main body is avoided.

[0013] Preferably, clamping strips are symmetrically and fixedly connected to the outer side of the fixing rod. A fan blade part is fixedly connected to the end of the fixing rod away from the electric motor part. The sleeve is slidably connected with the clamping strips. A return spring is sleeved on the outer side of the fixing rod. Both ends of the return spring are fixedly connected with fixing rings. One fixing ring abuts against the left fixing plate, and the other fixing ring abuts against the sleeve.

[0014] By adopting the above technical solution, the fixing rod will drive the fan blade part to rotate synchronously. The fan blade part blows air to the bottom of the high-voltage motor main body for heat dissipation. The return spring is used to assist the sliding and resetting of the sleeve and the rotating ring.

[0015] Preferably, a rotating part is fixedly connected to the side of the rotating ring close to the fixing ring. The rotating part is rotatably installed with the fixing ring. The first gear ring and the second gear ring are both arranged in an array. Limiting rings are also symmetrically and fixedly connected to the outer side of the rotating ring. The two limiting rings are respectively located on both sides of the first gear ring. The second gear ring is located below the middle of the two limiting rings.

[0016] By adopting the above technical solution, the sleeve can drive the first gear ring and the rotating ring to rotate through the cooperation of the second gear ring. The rotating ring drives the rotating member to rotate inside the fixed ring, so that the rotating ring will also rotate by itself.

[0017] Preferably, an arc-shaped block is fixedly connected to one side of the outer part of the sleeve close to the motor part. The arc-shaped blocks are arranged in an array, and there are no less than three arc-shaped blocks. Adjusting grooves are arranged in an array on the inner side of the rotating ring. There are no less than four adjusting grooves, and a sliding rod is slidably connected inside the adjusting groove.

[0018] By adopting the above technical solution, when the sliding rod rotates to contact the arc-shaped block, the arc-shaped block presses the sliding rod.

[0019] Preferably, one end of the sliding rod is fixedly connected with a pressing block. The pressing block is slidably connected with the adjusting groove. A pressing spring is sleeved on the outer side of the sliding rod. Two ends of the pressing spring are respectively fixedly connected with the inner wall of the adjusting groove and the pressing block.

[0020] By adopting the above technical solution, the sliding rod stretches the pressing spring and drives the pressing block to move, so that the pressing block slides out and presses against the outer side of the high-voltage motor main body. An arc-shaped plate can be installed at the end of the pressing block.

[0021] Preferably, the ventilation component includes air ducts symmetrically opened in the upper parts of both sides of the insulating shell. A drying plate is fixedly installed inside the air ducts. A cover shell is also fixedly installed on the upper part of the other side of the insulating shell. The cover shell is used to seal the air duct on the right side.

[0022] By adopting the above technical solution, the left air duct is used for air intake, and the right air duct is used for air outlet. By pumping air through an external connecting pipe, the air passes through the drying plate to remove water and is filtered by the inclined filter plate.

[0023] Preferably, an external connecting pipe is fixedly installed on the outer part of the cover shell. Inclined filter plates are symmetrically and fixedly connected above the inner part of the insulating shell. The ventilation component further includes two symmetrically arranged collecting boxes. The collecting boxes are fixedly installed on the inner wall of the insulating shell. The collecting boxes are located below the inclined filter plates.

[0024] By adopting the above technical solution, the hot air is discharged from the external connecting pipe through the right air duct. The collecting boxes are used to collect particulate impurities.

[0025] Preferably, positioning bolts are symmetrically installed on both sides of the insulating shell. The positioning bolts are threadedly connected with the insulating shell. One end of the positioning bolt is fixedly connected with a positioning disc. The positioning disc is located inside the insulating shell. A receiving groove is opened in the lower part of the inner side of the insulating shell. The positioning disc is snap-fitted with the receiving groove.

[0026] By adopting the above technical solution, the positioning bolts on both sides are rotated, and the positioning bolts drive the positioning disks to tightly press against both sides of the high-voltage motor main body, facilitating the positioning of the high-voltage motor main body.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. An insulation protection component is provided. The operator passes the output shaft of the high-voltage motor main body through the insulating sleeve ring, and fixedly installs the insulating shell on the base, so that the fixing plate supports the high-voltage motor main body. The first gear ring meshes with the second gear ring. Then, the positioning bolts on both sides are rotated, and the positioning bolts drive the positioning disks to tightly press against both sides of the high-voltage motor main body, facilitating the positioning of the high-voltage motor main body. By starting the linear motor and the motor part to work, the sliding table guides the moving seat. The linear motor can drive the moving seat to move linearly back and forth. When the moving seat moves, it will pull the pull rope. The pull rope is guided by the guide roller and drives the sliding plate to move. The sliding plate slides on the inner top surface of the insulating shell and drives the fixed ring to move. The fixed ring drives the rotating ring to move, so that the rotating ring performs dust cleaning treatment on the outside of the high-voltage motor main body, thereby improving the heat dissipation efficiency of the high-voltage motor main body. Through the cooperation of the limiting ring, the rotating ring can drive the second gear ring and the sleeve to move linearly. The sleeve slides on the outside of the fixed rod. The clamping strips provided on the outside of the fixed rod ensure the synchronous rotation of the fixed rod and the sleeve. When the sleeve moves, it will squeeze the return spring through the fixed ring. The return spring is used to assist the sliding and reset of the sleeve and the rotating ring. The motor part drives the fixed rod and the sleeve to rotate. Through the cooperation of the sleeve and the second gear ring, it can drive the first gear ring and the rotating ring to rotate. The rotating ring drives the rotating part to rotate inside the fixed ring, so that the rotating ring will also rotate by itself, further improving the dust cleaning effect. And when the sliding rod rotates to contact the arc-shaped block, the arc-shaped block squeezes the sliding rod. The sliding rod stretches the pressing spring and drives the pressing block to move, so that the pressing block slides out and presses against the outside of the high-voltage motor main body. An arc-shaped plate can be installed at the end of the pressing block. Through the extrusion and scraping of the arc-shaped plate and the movement and self-rotation scraping of the rotating ring, the obstruction of dust and the like to the heat dissipation of the high-voltage motor main body is reduced, and the problem that the temperature of the high-voltage motor main body is too high is avoided. It solves the problem that when the motor is sealed and protected by the outer shell, it is not convenient for the heat generated by the motor during operation to be discharged in time, which may cause the aging of the insulating material and reduce the insulation performance of the high-voltage motor.

[0029] 2. A ventilation component is provided. The left air duct is used for air intake, and the right air duct is used for air exhaust. During use, the operator connects the external connecting pipe to the pipeline of the external exhaust equipment, and exhausts air through the external connecting pipe. External air enters from the left air duct. The air is dehumidified by the drying plate and filtered by the inclined filter plate to reduce the influence of water vapor on the insulation effect of the high-voltage motor main body, and drives the hot air inside the insulating shell to move. The hot air is discharged from the external connecting pipe through the right air duct. The collection box is used to collect particulate debris. When the motor part drives the fixed rod to rotate, the fixed rod will drive the fan part to rotate synchronously. The fan part blows air to the bottom of the high-voltage motor main body to dissipate heat, thereby assisting in the heat dissipation of the high-voltage motor main body, and solving the problem that when the motor works in a humid environment, the moisture in the air will also reduce the insulation performance, and even cause the motor winding to crack, discolor or peel off.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1 - 3 , the present invention provides a technical solution: an insulating structure for a high-voltage motor, including an insulating shell 1, a high-voltage motor main body 3, and a base 2 fixedly installed at the bottom of the insulating shell 1 by bolts. An insulating sleeve ring 4 is fixedly installed at the lower part of one side of the insulating shell 1.

[0047] An insulating protection component 5 is arranged in the middle of the insulating shell 1. The insulating protection component 5 includes a moving unit and a rotating unit. The moving unit includes a moving seat 53 that can linearly slide on the top of the insulating shell 1. A pulling rope 55 is fixedly connected to the bottom of the moving seat 53. The pulling rope 55 passes through the insulating shell 1 and is connected to a sliding plate 56. A circular groove is opened at the top of the insulating shell 1. The pulling rope 55 passes through the circular groove and is fixedly connected to the sliding plate 56. A fixing ring 57 is fixedly connected to the bottom of the sliding plate 56. A rotating ring 58 is rotatably installed on one side of the fixing ring 57.

[0048] At the top of the insulating shell 1, a linear motor 51 and a sliding table 52 are fixedly installed. The linear motor 51 drives the moving seat 53 to slide outside the sliding table 52. On one side of the inner top surface of the insulating shell 1, a guiding roller 54 is fixedly installed. One end of the pulling rope 55 away from the moving seat 53 bypasses the guiding roller 54 and is fixedly connected to the sliding plate 56. The pulling rope 55 is slidably connected to the insulating shell 1. In the middle of the inner top surface of the insulating shell 1, a guiding groove is opened, and the sliding plate 56 is slidably connected to the guiding groove.

[0049] The rotating unit includes fixing plates 59 symmetrically and fixedly installed on both sides of the inner bottom surface of the base 2. Outside the left fixing plate 59, a motor part 510 is fixedly installed. The output end of the motor part 510 passes through the left fixing plate 59 and is fixedly connected to a fixing rod 511. A sleeve 513 is slidably installed on the outside of the fixing rod 511, and the sleeve 513 can slide on the outside of the fixing rod 511. A first gear ring 517 is fixedly connected to the outside of the rotating ring 58, and a second gear ring 519 is fixedly connected to the outside of the sleeve 513. The first gear ring 517 is meshed and connected with the second gear ring 519.

[0050] On the outside of the fixing rod 511, clamping bars are symmetrically and fixedly connected. One end of the fixing rod 511 away from the motor part 510 is fixedly connected to a fan blade part 512. The sleeve 513 is slidably connected to the clamping bars. A return spring 514 is sleeved on the outside of the fixing rod 511. Both ends of the return spring 514 are fixedly connected with fixing rings 515. One fixing ring 515 abuts against the left fixing plate 59, and the other fixing ring 515 abuts against the sleeve 513.

[0051] On the side of the rotating ring 58 close to the fixed ring 57, a rotating part 516 is fixedly connected. The rotating part 516 is rotatably installed with the fixed ring 57. The first gear ring 517 and the second gear ring 519 are both arranged in an array. On the outside of the rotating ring 58, limiting rings 518 are also symmetrically and fixedly connected. The two limiting rings 518 are respectively located on both sides of the first gear ring 517, and the second gear ring 519 is located below the middle of the two limiting rings 518.

[0052] On the outside of the sleeve 513, close to one side of the motor part 510, arc-shaped blocks 520 are fixedly connected. The arc-shaped blocks 520 are arranged in an array, and there are no less than three arc-shaped blocks 520. On the inner side of the rotating ring 58, adjusting grooves 521 are arrayed. There are no less than four adjusting grooves 521. A sliding rod 522 is slidably connected inside the adjusting groove 521.

[0053] On both sides of the insulating shell 1, positioning bolts 7 are symmetrically installed. The positioning bolts 7 are threadedly connected to the insulating shell 1. One end of the positioning bolt 7 is fixedly connected to a positioning disc 8. The positioning disc 8 is located inside the insulating shell 1. A storage groove is opened in the lower part of the inner side of the insulating shell 1, and the positioning disc 8 is snap-fitted with the storage groove.

[0054] Example 1: As Figures 4 - 12As shown, the operator passes the output shaft of the high-voltage motor main body 3 through the insulating sleeve ring 4, and fixedly installs the insulating shell 1 and the base 2, so that the fixing plate 59 supports the high-voltage motor main body 3, the first gear ring 517 meshes with the second gear ring 519, and then rotates the positioning bolts 7 on both sides. The positioning bolts 7 drive the positioning disc 8 to tightly press against both sides of the high-voltage motor main body 3, facilitating the positioning of the high-voltage motor main body 3.

[0055] By starting the linear motor 51 and the motor part 510 to work, the sliding table 52 guides the moving seat 53. The linear motor 51 can drive the moving seat 53 to move linearly back and forth. When the moving seat 53 moves, it will pull the pull rope 55. The pull rope 55 is guided by the guide roller 54 and will drive the sliding plate 56 to move. The sliding plate 56 slides on the inner top surface of the insulating shell 1 and drives the fixed ring 57 to move. The fixed ring 57 drives the rotating ring 58 to move, so that the rotating ring 58 performs dust cleaning on the outside of the high-voltage motor main body 3, thereby improving the heat dissipation efficiency of the high-voltage motor main body 3.

[0056] Through the cooperation of the limiting ring 518, the rotating ring 58 can drive the second gear ring 519 and the sleeve 513 to move linearly. The sleeve 513 slides on the outside of the fixed rod 511. The clamping strips arranged on the outside of the fixed rod 511 ensure the synchronous rotation of the fixed rod 511 and the sleeve 513. When the sleeve 513 moves, it will squeeze the return spring 514 through the fixed ring 515. The return spring 514 is used to assist the sliding and reset of the sleeve 513 and the rotating ring 58. The motor part 510 will drive the fixed rod 511 and the sleeve 513 to rotate.

[0057] Through the cooperation of the second gear ring 519, the sleeve 513 can drive the first gear ring 517 and the rotating ring 58 to rotate. The rotating ring 58 drives the rotating part 516 to rotate inside the fixed ring 57, so that the rotating ring 58 will also rotate by itself, further improving the dust cleaning effect. And when the sliding rod 522 rotates to contact the arc-shaped block 520, the arc-shaped block 520 squeezes the sliding rod 522. The sliding rod 522 stretches the pressing spring 524 and drives the pressing block 523 to move, so that the pressing block 523 slides out and presses against the outside of the high-voltage motor main body 3. An arc-shaped plate can be installed at the end of the pressing block 523. Through the extrusion scraping of the arc-shaped plate and the movement and self-rotation scraping of the rotating ring 58, the obstruction of heat dissipation of the high-voltage motor main body 3 by dust and the like is reduced, avoiding the overheating of the high-voltage motor main body 3, and solving the problem that when the motor is sealed and protected by the outer shell, it is not convenient for the heat generated by the motor during operation to be discharged in time, which may cause the aging of the insulating material and reduce the insulation performance of the high-voltage motor.

[0058] A ventilation component 6 is arranged above the inside of the insulating shell 1. The ventilation component 6 includes air ducts 61 symmetrically opened in the upper parts of both sides of the insulating shell 1. A drying plate 62 is fixedly installed inside the air ducts 61. A cover shell 63 is also fixedly installed on the upper part of the other side of the insulating shell 1. The cover shell 63 is used to seal the right air duct 61.

[0059] An external connection pipe 64 is fixedly installed outside the housing 63. Above the interior of the insulating housing 1, inclined filter plates 65 are symmetrically and fixedly connected. The ventilation assembly 6 further includes two collecting boxes 66 symmetrically arranged. The collecting boxes 66 are fixedly installed on the inner wall of the insulating housing 1 and are located below the inclined filter plates 65.

[0060] Embodiment 2: As Figures 13 - 14 shown, the left air duct 61 is used for air intake, and the right air duct 61 is used for air outlet. During use, the operator connects the external connection pipe 64 to the pipeline of an external air extraction device. Air is extracted through the external connection pipe 64. External air enters from the left air duct 61. The air passes through the drying plate 62 to remove water and the inclined filter plates 65 for filtration, reducing the influence of water vapor on the insulation effect of the high-voltage motor main body 3 and driving the hot air inside the insulating housing 1 to move.

[0061] The hot air is discharged from the external connection pipe 64 through the right air duct 61. The collecting boxes 66 are used to collect particulate debris. When the motor part 510 drives the fixed rod 511 to rotate, the fixed rod 511 will drive the fan part 512 to rotate synchronously. The fan part 512 blows air at the bottom of the high-voltage motor main body 3 to assist in dissipating heat from the high-voltage motor main body 3, solving the problem that when the motor works in a humid environment, the moisture in the air will also reduce the insulation performance, and even cause the motor winding to crack, discolor or peel off.

[0062] Working principle: When using this device, first, as Figures 1 - 14 shown, the operator fixedly installs the insulating housing 1 on the base 2. The positioning disks 8 are pressed against both sides of the high-voltage motor main body 3. The external connection pipe 64 is connected to the pipeline of an external air extraction device. Air is extracted through the external connection pipe 64. External air enters from the left air duct 61. The air passes through the drying plate 62 to remove water and the inclined filter plates 65 for filtration. The hot air is discharged from the external connection pipe 64 through the right air duct 61. The collecting boxes 66 are used to collect particulate debris. The fan part 512 blows air at the bottom of the high-voltage motor main body 3 to dissipate heat. By starting the linear motor 51 and the motor part 510 to work, the linear motor 51 can drive the moving seat 53 to reciprocate linearly. The movement of the moving seat 53 will pull the pull rope 55, causing the rotating ring 58 to move and clean the ash on the outside of the high-voltage motor main body 3. The rotating ring 58 can drive the second gear ring 519 and the sleeve 513 to move linearly. The return spring 514 is used to assist the sliding and reset of the sleeve 513 and the rotating ring 58. The motor part 510 will drive the fixed rod 511 and the sleeve 513 to rotate, causing the rotating ring 58 to also rotate simultaneously. When the sliding rod 522 rotates to contact the arc-shaped block 520, the pressing block 523 slides out and presses against the outside of the high-voltage motor main body 3. An arc-shaped plate can be installed at the end of the pressing block 523. Through the extrusion and scraping cooperation of the arc-shaped plate and the movement and rotation of the rotating ring 58 for scraping, the obstruction of heat dissipation of the high-voltage motor main body 3 by dust and the like is reduced.
