Description

Technical Field

[0001] The invention belongs to the technical field of permanent magnet electric rollers, and in particular relates to a direct-driven permanent magnet electric roller device. Background Art

[0002] In many industrial transmission scenarios, such as mines, ports, logistics warehousing and other fields, electric rollers are widely used as key power transmission equipment. Traditional electric rollers have some shortcomings. For example, in terms of heat dissipation, a large amount of heat is generated due to long-term operation. If the heat is not dissipated in time, the equipment temperature will be too high, affecting the performance of permanent magnets, reducing motor efficiency and even shortening the service life of the equipment.

[0003] The Chinese patent with the authorization announcement number CN216489963U discloses an air-cooled permanent magnet drum motor. The rotor drum rotates under the action of the magnetic field, thereby driving the breathable end cover to rotate. The breathable end cover drives the fan to rotate through the intermediate connector. During operation, the heat generated by the stator will increase the air temperature in the rotor drum. The rotating fan will promote the flow of air in the rotor drum, discharge the hotter air out of the rotor drum, and draw the cooler external air into the rotor drum, thereby taking away the heat generated by the stator and achieving heat dissipation and cooling of the stator. Moreover, the heat dissipation support assembly is arranged at both ends of the rotor drum, and the installation direction and rotation direction of the fan are the same. The effects of the fans at both ends are superimposed on each other, which can further enhance the flow rate of the gas.

[0004] However, this technical solution still has at least the following defects: a conventional permanent magnet electric drum (equivalent to a permanent magnet drum motor) is provided with a driver at the end, which makes it inconvenient to install the heat dissipation support assembly at both ends at the same time. When the heat dissipation support assembly is installed at only one end for circulating heat dissipation, it is difficult to ensure that the airflow circulates fully inside the permanent magnet electric drum. At the same time, the above solution needs to keep the inside of the permanent magnet electric drum connected to the outside during the heat dissipation process, which will cause dust in the air to enter the inside of the permanent magnet electric drum and cause damage. In view of this, the present invention is specially proposed. Summary of the invention

[0033] The implementation principle of a direct-driven permanent magnet electric roller device of this embodiment is as follows: when the permanent magnet electric roller 100 is working, it will drive the inner gear ring 101 to rotate, the inner gear ring 101 drives the first gear 102 to rotate, the first gear 102 drives the second gear 103 to rotate, and the second gear 103 drives the rotating ring 105 to rotate by meshing with the outer gear ring 106, so as to rotate the fan blade 107, and the fan blade 107 transports the hot air inside the permanent magnet electric roller 100 to the cooling unit through the first connecting pipe 109, and cools down under the contact of the multi-layer heat sink 203, and the heat sink 203 is connected to the coolant through the connector 204 to quickly achieve cooling, and at the same time, the air gradually moves to the outer ring after passing through the multi-layer heat sink 203, and enters the air box 300 through the guide pipe 501, and then enters the permanent magnet electric roller 100 through the second connecting pipe 301, so as to realize air circulation; The second gear 103 rotates while driving the second bevel gear 407 to rotate, the second bevel gear 407 drives the first bevel gear 406 to rotate, the first bevel gear 406 drives the second sprocket 404 to rotate through the rotating shaft 405, and then drives the first sprocket 402 to rotate through the chain 403, the first sprocket 402 drives the worm wheel 400 to rotate through the worm 401, and the worm wheel 400 drives the toggle plate 309 to rotate, at this time, the toggle plate 309 abuts against the first push rod 307 through the groove 310 and the slider 308, thereby pushing the connecting block 306 to move, and pulling the movable rod 303 and the piston 302 during the movement, at this time the first spring 304 is in a compressed state; When one end of the toggle plate 309 rotates to the guide block 509, the toggle plate 309 drives the limit block 508 to move by pushing the guide block 509. At this time, the limit block 508 drives the hook lock 506 to deflect upward by resisting the top rod 507 and disengages from the connecting plate 505. At this time, the tension of the second spring 504 drives the connecting plate 505 to move, thereby moving the blocking block 502 and blocking the guide tube 501. At this time, the air box 300 is connected to the permanent magnet electric drum 100 only through the second connecting tube 301. When the toggle plate 309 rotates to a state parallel to the first push rod 307, the slider 308 is aligned with the slide groove 311. At this time, the slider 308 is no longer blocked by the groove 310 and slides in the slide groove 311. At the same time, the elastic force of the first spring 304 acts on the piston 302 and causes the piston 302 to move quickly, so that the air accumulated in the air box 300 is quickly blown into the deep part of the permanent magnet electric drum 100, so that the heat exchange effect is more comprehensive. When the piston 302 moves to the end of the air box 300, it pushes the third push rod 513 to move, and the third push rod 513 pushes the second push rod 510 to move through the rocker plate 512, thereby driving the connecting plate 505 to reset, and the connecting plate 505 drives the blocking block 502 to reset, so that the air box 300 and the guide tube 501 are connected again; At the same time, the slider 308 moves to the groove 310 at the other end of the toggle plate 309. When the toggle plate 309 continues to rotate, the first push rod 307 continues to move through the groove 310 and the slider 308 to continue to move the piston 302. When the toggle plate 309 is offset from the guide block 509, the hook lock 506 descends under the action of gravity and re-locks the connecting plate 505.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
