The motor includes a stator and a rotor. The stator includes a stator core and a coil winding wound on the stator core. The rotor includes a rotating shaft and a rotor core sleeved on the rotating shaft. A permanent magnet is provided on the outer edge of the rotor core. When the internal parts of the motor are working, heat is generated on the motor casing. The motor casing is usually equipped with cooling fins to quickly disperse the heat to protect the motor.
[0003] Existing motors are widely used in factories, outdoor places and other dusty places. When a large amount of dust covers the surface of the heat sink fins, the heat dissipation capacity of the heat sink fins will be greatly reduced, resulting in excessive heat inside the motor and shortening the service life of the motor. The surface of the heat sink fins is full of grooves, which makes manual cleaning time-consuming and labor-intensive, and not easy to clean. Therefore, an integrated motor casing is urgently needed. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide an integrated motor casing to solve the problem that motors are widely used in factories, outdoors and other dusty places. When dust covers the surface of the cooling fins in large quantities, the heat dissipation capacity of the cooling fins will be greatly reduced, resulting in excessive heat inside the motor, shortening the service life of the motor, and the surface of the cooling fins is full of grooves, which makes manual cleaning time-consuming and labor-intensive, and not easy to clean.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated motor casing, comprising a motor housing and an arc-shaped plate, wherein the outer surface of the motor housing is provided with heat dissipation fins, and the lower end of the motor housing is integrally welded with a base, and a mounting platform is arranged below the base.
[0006] The arc plate covers the outer side of the heat dissipation fin, and a cleaning cotton is fixedly installed on the inner wall of the arc plate. Limiting plates are welded on both sides of the arc plate, and a circular hole is opened inside the limiting plate. A long rod passes through the inside of the circular hole, and a connecting rod is integrated at the rear end of the long rod.
[0007] Preferably, connecting plates are fixedly provided on both left and right sides of the base, and countersunk threads are provided inside the connecting plates, and screws penetrate the inside of the countersunk threads.
[0008] Preferably, the arc-shaped plate is connected to the heat dissipation fins through cleaning cotton, and the outer surface of the heat dissipation fins is in contact with the cleaning cotton.
[0009] Preferably, a pull ring is fixedly mounted on the top end of the arc-shaped plate, and the outer side of the pull ring is covered with a rubber sleeve.
[0010] Preferably, two ends of the connecting rod are respectively fixed to the motor housing and the long rod, and the long rod passes through the limiting plate through a circular hole, and the inner wall of the circular hole is smooth.
[0011] Preferably, an external thread is distributed on the outer side of the front end of the long rod, and a nut is screwed on the outer side of the external thread.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model uses a connecting rod, a long rod, a limit plate and a round hole in coordination, so that the arc plate has the function of moving forward and backward. The heat generated during the operation of the motor is discharged through the heat dissipation fins. When a large amount of dust adheres to the surface of the heat dissipation fins, the worker holds the pull ring and pulls the arc plate back and forth, so that the cleaning cotton fits on the surface of the heat dissipation fins and moves, and the dust on the surface of the heat dissipation fins can be scraped off, which is conducive to the normal heat dissipation of the heat dissipation fins;
[0014] 2. In the utility model, the nut is threadedly connected to the front end of the long rod through an external thread, so the nut is detachable. When the cleaning cotton is damaged due to long-term use and cannot effectively clean the heat dissipation fins, the nut can be unscrewed to remove the arc plate, which is convenient for replacing the cleaning cotton.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0021] The following describes an embodiment of the utility model based on its overall structure.
[0022] See also Figure 1-4 An integrated motor housing includes a motor housing 1 and an arc-shaped plate 8. The outer surface of the motor housing 1 is provided with heat dissipation fins 2, and the lower end of the motor housing 1 is integrally welded with a base 3, a mounting platform 4 is arranged below the base 3, and connecting plates 5 are fixedly arranged on both sides of the left and right sides of the base 3, and a countersunk thread 6 is provided inside the connecting plate 5, and a screw 7 is passed through the inside of the countersunk thread 6. The base 3 of the motor housing 1 is fixed on the top of the mounting platform 4 by the use of the connecting plate 5, the countersunk thread 6 and the screw 7. Compared with welding, this connection method is detachable and can be replaced after damage;
[0023] The arc plate 8 covers the outer side of the heat dissipation fin 2, and a cleaning cotton 9 is fixedly installed on the inner wall of the arc plate 8. The arc plate 8 is connected to the heat dissipation fin 2 through the cleaning cotton 9, and the outer surface of the heat dissipation fin 2 is in contact with the cleaning cotton 9. The heat generated during the operation of the motor is discharged through the heat dissipation fin 2. Since most motors are installed in factories and other places, a large amount of dust is easily adhered to the surface of the heat dissipation fin 2. By moving the arc plate 8 back and forth, the cleaning cotton 9 is in contact with the surface of the heat dissipation fin 2 and moves, which is convenient for scraping off the dust on the surface of the heat dissipation fin 2, so that the heat dissipation fin 2 can dissipate heat normally. A pull ring 12 is fixedly installed on the top of the arc plate 8, and the outer side of the pull ring 12 is covered with a rubber sleeve 13. The arc plate 8 is pulled by the pull ring 12. The setting of the rubber sleeve 13 prevents the worker's fingers from being strangled when pulling the pull ring 12. Limiting plates 10 are welded on both sides of the arc plate 8, and a circular hole 11 is opened inside the limiting plate 10. The inside of the circular hole 11 A long rod 14 runs through it, and a connecting rod 15 is integrally provided at the rear end of the long rod 14. The two ends of the connecting rod 15 are respectively fixed to the motor housing 1 and the long rod 14, and the long rod 14 passes through the limit plate 10 through the circular hole 11, and the inner wall of the circular hole 11 is smooth. Through the coordinated use of the connecting rod 15, the long rod 14, the limit plate 10 and the circular hole 11, the moving direction of the arc plate 8 is fixed, which is convenient for the cleaning cotton 9 to move back and forth to scrape off the dust adhered to the surface of the heat dissipation fin 2. An external thread 16 is distributed on the outer side of the front end of the long rod 14, and a nut 17 is screwed on the outer side of the external thread 16. The nut 17 is threadedly connected to the front end of the long rod 14 through the external thread 16, so the nut 17 is detachable. When the cleaning cotton 9 is severely damaged after long-term use and cannot effectively clean the heat dissipation fin 2, the nut 17 can be unscrewed to remove the arc plate 8. The cleaning cotton 9 is fixed to the arc plate 8 by Velcro, so only the cleaning cotton 9 needs to be replaced.
[0024] Working principle: When in use, the base 3 of the motor housing 1 is fixed on the top of the mounting platform 4 through the connection plate 5, countersunk thread 6 and screws 7. The heat generated during the operation of the motor is discharged through the heat dissipation fins 2. Since most motors are installed in dusty places such as factories, a large amount of dust is easily adhered to the surface of the heat dissipation fins 2. At this time, the staff holds the pull ring 12, and the connection rod 15, long rod 14, limit plate 10 and round hole 11 are used together to move the arc plate 8 back and forth, so that the cleaning cotton 9 fits on The surface of the heat dissipation fin 2 moves, which makes it easy to scrape off the dust on the surface of the heat dissipation fin 2, so that the heat dissipation fin 2 can dissipate heat normally. Since the inner wall of the circular hole 11 is smooth, the friction between the long rod 14 and the limit plate 10 is small, which is conducive to the flexible movement of the arc plate 8. The nut 17 is threadedly connected to the front end of the long rod 14 through the external thread 16, so the nut 17 is removable. When the cleaning cotton 9 is severely damaged due to long-term use and cannot effectively clean the heat dissipation fin 2, the nut 17 can be unscrewed, and then the arc plate 8 and the cleaning cotton 9 can be removed and replaced.
