Description

A high-low dual-voltage dual-frequency integrated shaded-pole motor

Technical Field

The present invention relates to the technical field of motors, and more specifically, to a high-low dual-voltage dual-frequency integrated shaded-pole motor.

Background technique

The high and low dual voltage dual frequency integrated shaded pole motor is a new type of motor that combines the technical characteristics of high and low voltage and dual frequency. This type of motor can meet the voltage and frequency requirements in different regions, that is, the voltage and frequency can be integrated into one motor, reducing the types of materials and increasing versatility. In order to prevent external water, dust and other impurities from affecting and damaging the motor, a protective shell is usually set on the outside of the motor. In order to solve the problem of motor heat dissipation, heat dissipation ports and heat dissipation fins are also required on the protective shell to dissipate the heat generated inside the motor from the heat dissipation ports in time to prevent heat accumulation in the motor and causing damage to the motor. A dustproof plate is also required at the heat dissipation port to prevent dust from entering the protective shell.

The current high and low dual voltage dual frequency integrated shaded pole motor dissipates heat through cooling fins, resulting in low heat dissipation efficiency. There is no air flow inside the protective shell, and the heat cannot be exported from the protective shell, resulting in heat accumulation in the protective shell and still causing damage to the motor. In addition, the area of the dust shield holes set on the heat dissipation port cannot be changed, resulting in the inability to meet the needs of rapid heat dissipation of the motor. When the motor needs to dissipate heat quickly, the smaller heat dissipation holes of the dust shield cannot quickly discharge heat. After the dust shield has been used for a long time, a large amount of dust and mosquito corpses will adhere to the side of the dust shield that is in contact with the outside world, causing the holes of the dust shield to be blocked, affecting the heat dissipation of the motor. The current motor cannot clean the dust shield.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Referring to Figures 1, 2 and 9, a high-low dual-voltage dual-frequency integrated shaded-pole motor includes a motor body 1, an output shaft 2 arranged on the motor body 1, an upper shell 3 and a lower shell 4 arranged outside the motor body 1, the upper shell 3 and the lower shell 4 are fixedly installed, a plurality of heat dissipation ports 5 are opened at the bottom of the lower shell 4, and a first dustproof plate 6 is arranged in each of the heat dissipation ports 5, a plurality of heat dissipation fins 7 are fixedly connected between the motor body 1 and the upper shell 3 and the lower shell 4, and a plurality of first heat dissipation holes 8 are opened on the heat dissipation fins 7, and further includes:

A cooling mechanism is arranged in the upper housing 3 and the lower housing 4, and the cooling mechanism is used to quickly dissipate heat and cool the motor body 1;

A detection component is provided on the top of the motor body 1, and the detection component is used to detect the heat generated by the motor body 1;

A replacement component is arranged on the lower housing 4, and the replacement component is used to change the area of the heat dissipation hole;

A scraping assembly is arranged on the lower shell 4, and the scraping assembly is used to scrape and clean the bottom of the first dustproof plate 6; when in use, the motor body 1 is protected by the upper shell 3 and the lower shell 4, which can prevent external dust, water and other substances from entering the interior of the motor body 1 and causing damage to the motor body 1. The output shaft 2 can be connected to an external structure that needs to be driven. During the operation of the motor body 1 driving the output shaft 2, the motor body 1 will generate heat, which will be dissipated to the upper shell 3 and the lower shell 4 through the heat dissipation fins 7 and the first heat dissipation holes 8. The heat is accumulated in the upper shell 3 and the lower shell 4, and the heat will be discharged through the heat dissipation port 5. The first dustproof plate 6 can prevent dust and mosquitoes from entering the upper shell 3 and the lower shell 4.

3 and 4, the cooling mechanism includes an air cooling component and a water cooling component. The air cooling component includes a transmission shaft 9 fixedly connected to the bottom end of the output shaft 2, and the bottom end of the transmission shaft 9 is fixedly connected to a heat dissipation fan blade 10. The water cooling component includes a spiral cooling tube 11 fixedly connected to the heat dissipation fin 7, and a connecting tube 12 is fixedly connected between the two ends of the cooling tube 11. The internal rotation of the connecting tube 12 is connected to a first rotating shaft 13, and the outer wall of the first rotating shaft 13 is fixedly connected to a plurality of rotating blades 14. When the motor body 1 is operating normally, the motor body 1 can drive the transmission shaft 9 to rotate through the output shaft 2, and the transmission shaft 9 drives the heat dissipation fan blade 10 to rotate. The heat dissipation fan blade 10 can rotate the upper shell 3 and the lower shell 4. The air is discharged from the heat dissipation port 5, thereby dissipating the heat generated by the motor body 1, accelerating the heat dissipation of the motor body 1, and achieving the purpose of air cooling the motor body 1. When the motor body 1 is overloaded for a long time, relying solely on air cooling to dissipate heat cannot meet the heat dissipation requirements. The heat in the upper shell 3 and the lower shell 4 will still accumulate and increase, so it is necessary to use a water cooling component for auxiliary heat dissipation. The rotating blades 14 are driven to rotate in the connecting tube 12 by the first rotating shaft 13. The rotating blades 14 can drive the coolant in the connecting tube 12 and the cooling tube 11 to circulate. The circulating coolant can take away the heat around the motor body 1 and the heat dissipation fins 7, thereby accelerating the heat dissipation of the motor body 1.

The induction block 23 is directly above the motor body 1; the motor body 1 generates heat during operation, and part of the heat will be transferred to the conical shell 15 through the heat dissipation block 16 and the second heat dissipation hole 17. As the heat in the conical shell 15 increases, the air in the conical shell 15 expands to lift the lifting block 20, the first spring 22 is compressed, and the lifting block 20 drives the contact block 21 to move. When the heat accumulation in the upper shell 3 and the lower shell 4 increases, it means that the heat cannot be discharged in time. The greater the movement distance of the contact block 21, until the contact block 21 contacts the induction block 23, the system can know that there is too much heat in the upper shell 3 and the lower shell 4, and the water cooling component can be started to assist in heat dissipation.

The first dustproof plate 6 is slidably inserted in the storage groove 48. A plurality of second dustproof plates 49 located directly above the corresponding heat dissipation ports 5 are fixedly connected to the inner wall of the bottom of the lower shell 4. The heat dissipation holes of the second dustproof plates 49 are larger than those of the first dustproof plates 49. The heat dissipation hole size of the dustproof plate 6, the second dustproof plate 49 is provided with an avoidance opening for avoiding the connecting rod 47; when the water cooling component is needed for heat dissipation, the micro-electric cylinder 30 will drive the connecting frame 31 to move, the connecting frame 31 can drive the L-shaped block 39 to move, the L-shaped block 39 drives the connecting plate 40 and the fixed shaft 41 to move, the fixed shaft 41 drives the fourth rotating shaft 43 to rotate through the limit block 42 and the limit opening, the fourth rotating shaft 43 can drive the circular gear 44 to rotate, the circular gear 44 can drive the rack 45 to operate, and the gear The strip 45 drives the multiple first dustproof plates 6 to move through the cross bar 46 and the connecting rod 47, so that the first dustproof plate 6 enters the storage groove 48, and the second dustproof plate 49 is in contact with the outside world and prevents dust and other impurities from entering the shell. Since the heat dissipation hole size of the second dustproof plate 49 is larger than the heat dissipation hole size of the first dustproof plate 6, the heat dissipation efficiency of the second dustproof plate 49 is better. When rapid heat dissipation is not required, the first dustproof plate 6 needs to be reset. The smaller heat dissipation holes of the first dustproof plate 6 can prevent fine dust and mosquitoes from entering.

Referring to Figure 11, the scraping assembly includes a scraper rod 50 fixedly connected to a side wall of the heat dissipation port 5, the top end of the scraper rod 50 contacts the bottom of the first dustproof plate 6, and a fixing rod 51 is fixedly connected to one side wall of the scraper rod 50.

When passing through the heat dissipation holes of the first dustproof plate 6, under the action of the third spring 54, the top cone 52 will pierce into the heat dissipation holes, and can break the impurities blocking the heat dissipation holes, so that the impurities fall out of the holes. Since the top end of the top cone 52 is set in a slope shape, the top cone 52 can smoothly leave the hole.

10, 11 and 12, the scraper rod 50 is provided with a vibration assembly, and the vibration assembly includes a rotating block 55 rotatably connected to the bottom of the scraper rod 50, and a side wall of the rotating block 55 is provided with an arc groove, and the bottom of the first dustproof plate 6 is fixedly connected with a toggle column 56 corresponding to the arc groove through an L-shaped plate, and a connecting rope 57 is fixedly connected to the bottom end of the rotating block 55, and a cavity 58 is provided in the scraper rod 50, and one end of the connecting rope 57 is fixedly connected to a collision block 59 slidably connected in the cavity 58, and the collision block 59 contacts with a side wall of the cavity 58, and a fourth spring is fixedly connected between the collision block 59 and the other side wall of the cavity 58 60; Before the first dustproof plate 6 is about to completely enter the storage groove 48, the toggle column 56 will contact the rotating block 55, causing the rotating block 55 to rotate, and the rotating block 55 pulls the impact block 59 to move through the connecting rope 57, causing the impact block 59 to leave one end of the cavity 58, and the fourth spring 60 is compressed. When the toggle column 56 is not in contact with the rotating block 55, under the action of the fourth spring 60, the impact block 59 suddenly hits the cavity 58, and the impact generates vibration.

The staff can observe the red ink and know that the motor body 1 generates too much heat. The motor body 1 is in overload operation and the state of the motor body 1 needs to be adjusted to prevent long-term overload from causing damage to the motor body 1. When the heat in the upper shell 3 and the lower shell 4 gradually decreases, under the action of the second spring 28, the red ink is reset, and the first rubber block 27 and the second rubber block 29 are reset.

Working principle: When in use, the motor body 1 is protected by the upper shell 3 and the lower shell 4, which can prevent external dust, water and other substances from entering the motor body 1 and causing damage to the motor body 1.

During the operation of the motor body 1 driving the output shaft 2, the motor body 1 will generate heat, which will be dissipated to the upper shell 3 and the lower shell 4 through the heat dissipation fins 7 and the first heat dissipation holes 8. The heat is accumulated in the upper shell 3 and the lower shell 4, and the heat will be discharged through the heat dissipation port 5. The first dustproof plate 6 can prevent dust and mosquitoes from entering the upper shell 3 and the lower shell 4; when the motor body 1 is operating normally, the motor body 1 can drive the transmission shaft 9 to rotate through the output shaft 2, and the transmission The shaft 9 drives the heat dissipation fan blades 10 to rotate, and the heat dissipation fan blades 10 can discharge the air in the upper shell 3 and the lower shell 4 from the heat dissipation port 5, so as to discharge the heat generated by the motor body 1, accelerate the heat dissipation of the motor body 1, and achieve the purpose of air cooling the motor body 1. When the motor body 1 is overloaded for a long time, the heat dissipation requirement cannot be met by simply relying on air cooling. The heat in the upper shell 3 and the lower shell 4 will still accumulate and increase, so it is necessary to use a water cooling component for auxiliary heat dissipation. The rotating blades 14 are driven to rotate in the connecting tube 12 by the first rotating shaft 13. The rotating blades 14 can drive the coolant in the connecting tube 12 and the cooling tube 11 to circulate, and the circulating coolant can take away the surrounding and heat dissipation of the motor body 1. The heat on the thermal fins 7 can accelerate the heat dissipation of the motor body 1; the motor body 1 will generate heat during operation, and part of the heat will be transferred to the conical shell 15 through the heat dissipation block 16 and the second heat dissipation hole 17. As the heat in the conical shell 15 increases, the air in the conical shell 15 expands and can lift the lifting block 20. The first spring 22 is compressed, and the lifting block 20 drives the contact block 21 to move. When the heat accumulation in the upper shell 3 and the lower shell 4 increases, it means that the heat cannot be discharged in time. The greater the movement distance of the contact block 21, until the contact block 21 contacts the induction block 23, the system can know that there is too much heat in the upper shell 3 and the lower shell 4, and the water cooling component can be started to assist in heat dissipation; when it is needed When the water cooling component is started for heat dissipation, the micro electric cylinder 30 is started, the micro electric cylinder 30 drives the connecting frame 31 to move, the connecting frame 31 drives the second rotating shaft 32 and the first bevel gear 35 to move toward the third bevel gear 38, so that the first bevel gear 35 is meshed with the third bevel gear 38, that is, the transmission shaft 9 can drive the first bevel gear 35 and the second rotating shaft 32 to rotate through the two second bevel gears 37, the third rotating shaft 36 and the third bevel gear 38, the second rotating shaft 32 drives the first rotating shaft 13 to rotate through the hexagonal prism 33 and the hexagonal groove 34, and the first rotating shaft 13 can drive the coolant to circulate in the cooling pipe 11 through the rotating blades 14 to dissipate heat and cool the motor body 1; when the water cooling component needs to be used for heat dissipation ... the second rotating The electric cylinder 30 drives the connecting frame 31 to move, the connecting frame 31 can drive the L-shaped block 39 to move, the L-shaped block 39 drives the connecting plate 40 and the fixed shaft 41 to move, the fixed shaft 41 drives the fourth rotating shaft 43 to rotate through the limit block 42 and the limit opening, the fourth rotating shaft 43 can drive the circular gear 44 to rotate, the circular gear 44 can drive the rack 45 to run, the rack 45 drives multiple first dustproof plates 6 to move through the cross bar 46 and the connecting rod 47, so that the first dustproof plate 6 enters the storage groove 48, the second dustproof plate 49 is in contact with the outside world and prevents dust and other impurities from entering the shell, because the heat dissipation hole size of the second dustproof plate 49 is larger than the heat dissipation hole size of the first dustproof plate 6, the heat dissipation efficiency of the second dustproof plate 49 Preferably, when rapid heat dissipation is not required, the first dustproof plate 6 needs to be reset. The heat dissipation holes of the first dustproof plate 6 are small to prevent fine dust and mosquitoes from entering. When the first dustproof plate 6 enters the storage groove 48, the scraper rod 50 can scrape and clean the bottom of the first dustproof plate 6 to scrape off the attached dust and mosquito corpses. When passing through the heat dissipation holes of the first dustproof plate 6, under the action of the third spring 54, the top cone 52 will penetrate into the heat dissipation holes, which can break the impurities blocking the heat dissipation holes and make the impurities fall out of the holes. Since the top of the top cone 52 is set in a slope shape, the top cone 52 can smoothly leave the hole. Before the first dustproof plate 6 is about to completely enter the storage groove 48, the toggle column 56 will contact with the rotating block 55. The contact block 59 is pulled by the connecting rope 57 to move the impact block 59, so that the impact block 59 leaves one end of the cavity 58, and the fourth spring 60 is compressed. When the toggle column 56 is not in contact with the rotating block 55, under the action of the fourth spring 60, the impact block 59 suddenly hits the cavity 58, and the impact generates vibration. The vibration can make the dust and mosquito corpses on the scraper rod 50 fall off, and the vibration is transmitted to the first dustproof plate 6, so that the impurities in the heat dissipation holes can fall out, and the impurities can be taken out after the first dustproof plate 6 leaves the storage groove 48; when the heat in the upper shell 3 and the lower shell 4 is increasing, the lifting block 20 drives the contact block 21 to move toward the sensing block 23. In this process, the lifting block 20 will first contact with the moving ring The lifting block 20 will drive the moving ring block 25 to move. The moving ring block 25 drives the first rubber block 27 to move upward through the vertical rod 24. The first rubber block 27 drives the second rubber block 29 to move through the red ink, so that the second spring 28 is compressed, and the red ink is pressed into the horizontal section of the L-shaped tube 26. The staff can observe the red ink and know that the motor body 1 generates too much heat. The motor body 1 is in overload operation and the state of the motor body 1 needs to be adjusted to prevent long-term overload from causing damage to the motor body 1. When the heat in the upper shell 3 and the lower shell 4 gradually decreases, under the action of the second spring 28, the red ink is reset, and the first rubber block 27 and the second rubber block 29 are reset.
