Description

Technical Field

[0001] This invention relates to the field of energy-saving motor technology, specifically to a box-type permanent magnet synchronous motor with a cooling mechanism. Background Technology

[0002] Box-type synchronous permanent magnet motors are compact, highly efficient, and energy-saving motors widely used in industrial drives, new energy vehicles, wind power generation, and other fields. The motor adopts a closed box structure, and the outer shell is usually made of cast iron or aluminum alloy, which has high strength and good heat dissipation. Box-type synchronous permanent magnet motors are a model of energy-saving motors through optimized electromagnetic design, the use of low-loss materials, and improved process technology.

[0003] Currently available box-type permanent magnet synchronous motors typically employ water cooling or air cooling for heat dissipation. In air cooling, the rotation of fan blades coaxial with the motor dissipates heat from the surrounding environment through airflow into the heat sink assembly, where it exchanges heat with the copper fins. The heat is then transferred from the hot air to the copper fins, and finally to the casing, dissipating heat to the outside. However, due to the continuous heat transfer from the airflow over time, dust easily accumulates on the heat sinks. If not cleaned regularly, this can affect the heat transfer efficiency of the heat sinks. To prevent dust residue from remaining inside the casing after cleaning, existing box-type permanent magnet motors usually require disassembly and cleaning of the heat sinks. Therefore, a new box-type permanent magnet synchronous motor is needed to solve this problem. Summary of the Invention

[0004] This invention provides a box-type permanent magnet synchronous motor with a cooling mechanism, which facilitates cleaning of dust in the gaps of the heat sink assembly without disassembly, and allows for easy removal of the cleaned dust. This solves the problem mentioned in the background section where the heat sink assembly is subjected to heat transfer from airflow over many years, making it prone to dust accumulation.

[0007] Preferably, an electric telescopic rod is fixedly installed on the outer wall of the fixed frame, and a first slider is fixedly connected to the output end of the electric telescopic rod. A limiting frame is slidably sleeved on the outer wall of the first slider, and a first sliding groove is opened on the outer wall of the limiting frame. The first slider is slidably connected to the inner wall of the first sliding groove.

[0008] A first guide rod is fixedly connected to the inner wall of the first slide groove, the first slider is slidably connected to the outer wall of the first guide rod, a first return spring is fixedly connected to the outer wall of the first slider, one end of the first return spring is fixedly connected to the inner wall of the first slide groove, and the outer wall of the limiting frame is fixedly connected to the outer wall of the movable frame.

[0009] Preferably, an inclined guide plate is fixedly connected to the outer wall of the second guide rod, and the inclined guide plate is fixed to the second guide rod at an inclined angle.

[0010] Preferably, the outer wall of the rotating plate is provided with a first upper moving groove, a second upper moving groove and a third upper moving groove, and the wave-shaped track groove, the first upper moving groove, the second upper moving groove and the third upper moving groove are interconnected.

[0011] Preferably, the inner wall of the wave-shaped trajectory groove is fixedly connected with a plurality of evenly distributed first protrusions, and the inner wall of the second upward moving groove is fixedly connected with a plurality of evenly distributed second protrusions, wherein both the first protrusions and the second protrusions are configured as hemispherical shapes.

[0012] Preferably, the outer wall of the radiator box is fixedly connected to an outer mounting frame, the inner wall of the outer mounting frame is slidably connected to a motor box, the outer walls of both the radiator box and the motor box are fixedly connected to multiple limiting blocks, the inner walls of the limiting blocks are threaded with fixing bolts, the outer walls of the radiator box and the motor box are fixedly connected to multiple fixing blocks, and the outer wall of the mounting frame is provided with multiple air inlets.

[0013] Preferably, a corrugated telescopic plate is fixedly connected to the inner wall of the radiator box, and the outer wall of the corrugated telescopic plate is fixedly connected to the outer wall of the rotating plate.

[0014] Preferably, the permanent magnet synchronous motor body is fixedly installed on the inner wall of the motor box, and a rotating shaft is rotatably installed on the inner wall of the permanent magnet synchronous motor body.

[0015] Preferably, a first rotating disk and a second rotating disk are fixedly connected to the outer wall of the rotating shaft, and multiple fan blades are fixedly installed on the inner walls of both the first rotating disk and the second rotating disk.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this invention, when the moving frame and the cleaning brush are brushing away the gaps in the heat sink assembly, they also perform left and right pressing operations at the same time. The left and right pressing can make the cleaning brush clean the clumps of dust adhering to the gaps in the heat sink assembly more deeply, and the left and right vibration can prevent dust from adhering to the cleaning brush and causing secondary pollution of the heat sink assembly.

[0018] Because the inclined guide plate is set to be inclined, dust that falls onto the inclined guide plate will roll down the inclined slope to the left side of the rotating plate.

[0019] As the ball slides along the wavy track groove, the moving frame, carrying the cleaning brush, moves intermittently upwards and then quickly downwards. The upward movement allows the cleaning brush to press against the bottom of the heat sink assembly for cleaning, while the up-and-down shaking can better vibrate and remove the dust stuck to the cleaning brush.

[0020] 2. In this invention, when the ball slides into the second upper groove along the first upper groove, the rotating plate is tilted to the left, which causes a gap to be created between the rotating plate and the outer wall of the radiator box. The tilted rotating plate causes the dust to roll down from right to left along the outer wall of the rotating plate to the outside, thus completing the discharge of dust.

[0021] 3. In this invention, when the ball slides along the surface of the second protrusion, it causes the ball and the second guide rod to move downward quickly and strike the second upward groove, that is, to strike the rotating plate. The striking can accelerate the dust on the tilted rotating plate to roll off to the outside. Attached Figure Description

[0038] The inner wall of the first slide groove 20 is fixedly connected to the first guide rod 17, the first slider 16 is slidably connected to the outer wall of the first guide rod 17, the outer wall of the first slider 16 is fixedly connected to the first return spring 18, one end of the first return spring 18 is fixedly connected to the inner wall of the first slide groove 20, and the outer wall of the limiting frame 19 is fixedly connected to the outer wall of the movable frame 21.

[0039] An inclined guide plate 26 is fixedly connected to the outer wall of the second guide rod 25. The inclined guide plate 26 is fixed to the second guide rod 25 at an inclined angle.

[0040] The outer wall of the rotating plate 24 is provided with a first upper moving groove 28, a second upper moving groove 29 and a third upper moving groove 32, and the wave-shaped track groove 27, the first upper moving groove 28, the second upper moving groove 29 and the third upper moving groove 32 are interconnected.

[0041] The inner wall of the wave-shaped track groove 27 is fixedly connected with a plurality of evenly distributed first protrusions 30, and the inner wall of the second upward moving groove 29 is fixedly connected with a plurality of evenly distributed second protrusions 31. Both the first protrusions 30 and the second protrusions 31 are set to a hemispherical shape.

[0042] The outer wall of the radiator box 1 is fixedly connected to the mounting frame 12, and the inner wall of the mounting frame 12 is slidably connected to the motor box 2. The outer walls of both the radiator box 1 and the motor box 2 are fixedly connected to multiple limiting blocks 13. The inner wall of the limiting block 13 is threadedly connected to fixing bolts 14. The outer walls of the radiator box 1 and the motor box 2 are fixedly connected to multiple fixing blocks 35. The outer wall of the mounting frame 9 is provided with multiple air inlets 36.

[0043] The permanent magnet synchronous motor body 3 is fixedly installed on the inner wall of the motor box 2, and the rotating shaft 4 is rotatably installed on the inner wall of the permanent magnet synchronous motor body 3.

[0044] The outer wall of the rotating shaft 4 is fixedly connected to a first rotating disk 5 and a second rotating disk 7, and multiple fan blades 6 are fixedly installed on the inner walls of both the first rotating disk 5 and the second rotating disk 7.

[0045] In this embodiment: When using the box-type synchronous permanent magnet motor, before putting it into use, the radiator box 1 and the motor box 2 are first docked and fixed. The radiator box 1 and the motor box 2 are hoisted separately by passing the hoisting rope through the fixing block 35 on the outer wall of the radiator box 1 and the motor box 2. Finally, the mounting frame 12 outside the radiator box 1 is fitted onto the upper end of the motor box 2, completing the initial docking of the radiator box 1 and the motor box 2.

[0046] At this time, the multiple limiting blocks 13 on the outer walls of the radiator box 1 and the motor box 2 are aligned vertically. Simply screw the fixing bolts 14 into the upper and lower limiting blocks 13 in sequence to complete the docking of the radiator box 1 and the motor box 2. Then, screw the nuts that match the fixing bolts 14 onto the outside of the fixing bolts 14 to complete the final reinforcement.

[0047] After the radiator box 1 and the motor box 2 are properly connected, when the permanent magnet synchronous motor body 3 operates, the permanent magnet synchronous motor body 3 rotates with the rotating shaft 4, which in turn drives the first rotating disk 5 and the second rotating disk 7 fixed on the outer wall of the rotating shaft 4 to rotate synchronously. The rotation of the first rotating disk 5 and the second rotating disk 7 will drive multiple fan blades 6 to rotate. The rotation of the fan blades 6 will transport the hot air in the motor box 2 to the multiple air guide plates 8. The multiple arc-shaped air guide plates 8 will finally transport the air to the air inlet 36 and enter the mounting frame 9 through the air inlet 36. After entering the mounting frame 9, the hot air will pass through the dense heat sink fin group 11. During the flow through the heat sink fin group 11, the heat in the hot air will be conducted to the copper heat sink fin group 11 through heat transfer, completing the heat exchange. The cooled air flows to the end of the heat sink fin group 11, and is then guided by the rotating second rotating disk 7 and the corresponding fan blades 6 to blow towards the permanent magnet synchronous motor body 3 for a new round of air blowing and cooling.

[0048] After the permanent magnet synchronous motor body 3 has been used for a period of time, the dust of the heat sink assembly 11 can be cleaned. At this time, the electric telescopic rod 15 is started. It should be noted that the electric telescopic rod 15 is set to reset after reaching the longest end. During the reset process of the output end of the electric telescopic rod 15, the first slider 16, the limit frame 19 and the moving frame 21 move as a whole. When the moving frame 21 moves, the cleaning brush 22 on the outer wall moves synchronously. When the cleaning brush 22 moves, it can slide and brush the gaps in the heat sink assembly 11.

[0049] When the moving frame 21 moves, the second guide rod 25 on the outer wall of the moving frame 21 moves synchronously. The ball bearing 33 at the end of the second guide rod 25 slides along the wavy track groove 27. When sliding along the wavy track groove 27, since the track of the wavy track groove 27 is set to be wavy, the ball bearing 33 will carry the second guide rod 25 and the moving frame 21 to move while performing small reciprocating movements and reset actions in the left and right directions. This allows the moving frame 21 and the cleaning brush 22 to perform left and right pressing operations while brushing the gaps in the heat sink assembly 11. The left and right pressing can make the cleaning brush 22 clean the clumps of dust stuck in the gaps of the heat sink assembly 11 more deeply, and the left and right vibration can prevent dust from sticking to the cleaning brush 22 and causing secondary pollution of the heat sink assembly 11.

[0050] Dust vibrating off the cleaning brush 22 falls onto the inclined guide plate 26 below. Since the inclined guide plate 26 is inclined, the dust falls onto the inclined guide plate 26 and rolls down the inclined slope to the left side of the rotating plate 24.

[0051] Furthermore, as the ball bearing 33 slides along the wavy track groove 27, it will slide past multiple first protrusions 30. Since the first protrusions 30 are hemispherical, when the ball bearing 33 slides and climbs along the outer wall of the first protrusions 30, it causes the ball bearing 33 to move upward a certain distance along with the second guide rod 25 and the moving frame 21. When it passes a single first protrusion 30, the ball bearing 33, along with the second guide rod 25 and the moving frame 21, quickly moves downward and resets due to gravity. Since there are multiple first protrusions 30, when the ball bearing 33 slides along the wavy track groove 27, it also causes the moving frame 21 to move upward intermittently and then quickly move downward along with the cleaning brush 22. The upward movement allows the cleaning brush 22 to press against the bottom of the heat sink assembly 11 for cleaning, while the up-and-down shaking can better vibrate and remove the dust stuck on the cleaning brush 22.

[0052] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 - Figure 10 The inner wall of the radiator box 1 is fixedly connected to a corrugated telescopic plate 34, and the outer wall of the corrugated telescopic plate 34 is fixedly connected to the outer wall of the rotating plate 24.

[0053] In this embodiment: when the ball bearing 33 slides to the lowest end of the wavy track groove 27, the output end of the electric telescopic rod 15 begins to extend, causing the ball bearing 33 to slide from the wavy track groove 27 into the first upward moving groove 28. As the trajectory of the first upward moving groove 28 moves to the upper left, the ball bearing 33, along with the second guide rod 25, moves to the left under force. This movement causes the cleaning brush 22 to deform and adapt. It should be noted that the wavy track groove 27 is located at the central axis of the rotating plate 24. When the ball bearing 33 slides along the first upward moving groove 28 into the second upward moving groove 29, since the second upward moving groove 29 is located slightly to the left of the central axis, and the ball bearing 33 and the second guide rod 25, along with the moving frame 21 and the cleaning brush, are in the second upward moving groove 29... The overall weight of the rotating plate 22 causes the left side of the rotating plate 24 to be pressed downward. It should be noted that the combined weight of the moving frame 21 and the cleaning brush 22 at the left position can be greater than the torsional force of the torsion spring 37, causing the torsion spring 37 to twist. This causes the rotating plate 24, along with the first guide rod 23, to deflect along one end of the rotating connection. The rotating plate 24 is in a state of tilting to the left. Due to the leftward tilt of the rotating plate 24, it presses down on the corrugated telescopic plate 34. The corrugated telescopic plate 34 is compressed downward, creating a gap between the rotating plate 24 and the outer wall of the radiator box 1. The tilted rotating plate 24 causes dust to roll down from right to left along the outer wall of the rotating plate 24 to the outside, completing the dust discharge.

[0054] Furthermore, since the second upper moving groove 29 is provided with multiple hemispherical second protrusions 31, when the ball 33 slides along the surface of the second protrusion 31, it causes the ball 33 and the second guide rod 25 to move upward. After passing the second protrusion 31, it quickly moves downward and resets due to gravity, causing the ball 33 and the second guide rod 25 to move downward and strike the second upper moving groove 29, that is, to strike the rotating plate 24. The striking can accelerate the dust on the tilted rotating plate 24 to roll off to the outside.

[0055] Once the ball bearing 33 slides into the third upward groove 32 along the second upward groove 29, a new round of cleaning operation begins.
