[0024] Furthermore, the cleaning assembly includes a scraper 13, a pull ring 14, a guide hole 15, a guide rod 16 and a spring B17. Guide holes 15 are opened at the top and bottom of one side of the mounting seat 1. The inner sides of the two groups of guide holes 15 are sleeved with guide rods 16. A pull ring 14 is commonly provided on one side of the two groups of guide rods 16. The inner sides of the two groups of pull rings 14 are provided with scrapers 13 that match the filter screen 8. The outer sides of the two groups of guide rods 16 are sleeved with springs B17. A limit block is provided on one side of the guide rod 16, and the diameter of the limit block is larger than the spring B17. The movable range of the guide rod 16 can be limited by the limit block. The operator can pull the pull ring 14 to clean six groups of filter screens 8 at one time, thereby improving the cleaning speed.

[0025] Furthermore, a groove matching with the swivel 9 is opened on one side of the outer side of the heat dissipation bin 2, and an annular groove is opened on one side of the inner side of the groove. Slide blocks matching with the annular groove are provided on the top and bottom of the inner side of the swivel 9. When the swivel 9 rotates, the slide block can be driven to rotate along the annular groove, thereby improving the rotation stability of the swivel 9.

[0026] Furthermore, an oil filling pipe is provided on the top of the mounting base 1 away from the heat dissipation bin 2, and a sealing cover is provided on one side of the oil filling pipe. Lubricating oil can be injected into the main bearing 6 through the oil filling pipe to ensure its lubrication effect and reduce friction heat.

[0027] Working principle: When installing the device, the shaft can be inserted into the inner side of the main bearing 6 and the auxiliary bearing 3 for installation, and at the same time, the four groups of pull ropes 18 are driven by rotating the swivel 9, and then the guide block 10 is pulled away from each other by the elastic force of the spring A11 through the pull rope 18. After the shaft is inserted, the swivel 9 is loosened. At this time, the elastic force of the spring A11 can be used to push the four groups of rollers 4 to clamp on the outside of the shaft, which can assist in limiting the shaft. Later, when the shaft is running, the four groups of rollers 4 can be driven to roll along the outside through the rotation of the shaft, so that the small impeller 5 can be driven to rotate through the roller 4, so that the external airflow enters the heat dissipation bin 2 through the air inlet 7, and then enters the mounting seat 1 through the heat dissipation bin 2, so as to cool the shaft bearing. When the airflow enters the heat dissipation bin 2, the dust in the airflow can be filtered through the filter 8 to prevent dust from entering the heat dissipation bin 2 and damaging the internal parts.

[0028] When the filter 8 needs to be cleaned, the operator only needs to pull the pull ring 14 to drive the pull ring 14 to move to one side along the guide of the guide rod 16 to overcome the elastic force of the spring B17. The scraper 13 can be used to scrape off the dust filtered by the six groups of filter screens 8 at one time, and the cleaning is very convenient. After cleaning, the elastic force of the spring B17 can be used to drive the pull ring 14 to reset.
