When maintenance is required, the vacuum pump body 1 can be maintained by opening the bin cover 3 through the provided maintenance bin 2. An observation window 4 is fixedly installed on the top surface of the bin cover 3. Through the provided observation window 4, it is convenient for staff to observe the internal working conditions from the outside, thereby improving the efficiency of fault point judgment. In this way, the bin cover 3 can be opened only when the fault is determined, thereby improving efficiency. A heat sink 5 is fixedly installed on the surface of the vacuum pump body 1. The heat generated during the operation of the vacuum pump body 1 can be conducted to the heat sink 5. At this time, heat can be dissipated through the heat sink 5, and the heat sink 5 is arranged in a circular shape on the surface of the vacuum pump body 1.

[0026] See also Figure 1-5 A heat-conducting block 6 is fixedly installed on the surface of the heat sink 5. The heat-conducting block 6 can also conduct the heat on the heat sink 5, and then the heat can be conducted to the long rod 8. The long rod 8 can then conduct part of the heat to the handle 10, so that when the handle 10 is pulled in winter and some cold areas, freezing of hands can be avoided. An auxiliary sheet 7 is fixedly installed on the side of the heat-conducting block 6. The heat dissipation effect can be further improved by the auxiliary sheet 7. The auxiliary sheets 7 are arranged at equal distances on the side of the heat-conducting block 6. A long rod 8 is set through the side of the heat-conducting block 6 and the bin cover 3. The long rod 8 is slidably connected to the heat-conducting block 6 and the bin cover 3. A brush plate 9 is fixedly installed on one end of the long rod 8, and a handle is fixedly installed on the other end of the long rod 8. 10. When there are residual stains on the observation window 4 that affect the staff's observation, the staff only needs to pull the handle 10 outward, and the handle 10 then drives the long rod 8 to move, and the long rod 8 then drives the brush plate 9 to move. The brush plate 9 can now rub the surface of the observation window 4, and the surface of the observation window 4 can be cleaned. A tension spring 11 is provided on the surface of the long rod 8, one end of the tension spring 11 is fixedly connected to the handle 10, and the other end of the tension spring 11 is fixedly connected to the heat conduction block 6. After releasing the handle 10, due to the tension of the tension spring 11, the tension spring 11 can also pull the handle 10 to move, and the handle 10 then drives the long rod 8 to move, and the long rod 8 can then drive the brush plate 9 to reset, to prevent the brush plate 9 from being displaced when not in use.

[0027] Embodiment 2

[0028] See also Figure 4-5The top surface of the mounting plate 12 is provided with a fixing mechanism, and the fixing mechanism includes a bolt 13, and the bolt 13 is inserted into the top surface of the mounting plate 12. A nut 14 is fixedly installed on the top of the bolt 13. The nut 14 is a hexagonal structure. When installing and fixing the vacuum pump body 1, it is only necessary to fit the mounting plate 12 to the mounting surface, and then screw the bolt 13 into the mounting plate 12 and the mounting surface. At this time, the vacuum pump body 1 can be fixed. A slide groove 15 is provided on the top surface of the mounting plate 12, and a slider 16 is slidably connected to the inner wall of the slide groove 15. A moving block 17 is fixedly installed on the top of the slider 16, and a card plate 18 is fixedly installed on the side of the moving block 17. A vertical block 19 is fixedly installed on the top surface, and a threaded rod 20 is rotatably connected to the side of the moving block 17. When the threaded rod 20 is turned, since the vertical block 19 is provided with threads inside, the threaded rod 20 can move inside the vertical block 19. The threaded rod 20 then drives the moving block 17 to move. The moving block 17 then slides in the slide groove 15 through the slider 16. The moving block 17 then drives the clamping plate 18 to move until the clamping plate 18 blocks the nut 14. At this time, the bolt 13 can be prevented from loosening, thereby improving the stability of the bolt 13 and avoiding accidental falling off. The vertical block 19 is provided with threads inside, and the threads are meshed with the threaded rod 20.

[0029] Working principle: the heat generated during the operation of the vacuum pump body 1 can be conducted to the heat sink 5, and the heat sink 5 can be used for heat dissipation. At the same time, through the maintenance bin 2, when maintenance is needed, the vacuum pump body 1 can be maintained by only opening the bin cover 3, and the observation window 4 is provided, which is convenient for the staff to observe the internal working conditions from the outside, thereby improving the efficiency of fault point judgment. In this way, the bin cover 3 can be opened only when the fault is determined, which improves the efficiency. When there are residual stains on the observation window 4 that affect the staff's observation, the staff only needs to pull the handle 10 outwards, and the handle 10 then drives the long rod 8 to move, and the long rod 8 then drives the brush plate 9 to move. The brush plate 9 can then rub the surface of the observation window 4, and the surface of the observation window 4 can be cleaned. At the same time, after releasing the handle 10, due to the tension of the tension spring 11, the tension spring 11 can also pull the handle 10 to move, and the handle 10 then drives the long rod 8 to move, and the long rod 8 then drives the brush plate 9 to reset, so as to avoid the brush plate 9 from being used. When the vacuum pump body 1 is installed, it only needs to fit the mounting plate 12 to the mounting surface, and then screw the bolts 13 into the mounting plate 12 and the mounting surface. At this time, the vacuum pump body 1 can be fixed, and the staff can also screw the threaded rod 20. At this time, since the interior of the vertical block 19 is provided with threads, the threaded rod 20 can move inside the vertical block 19 at this time, and the threaded rod 20 then drives the moving block 17 to move. The moving block 17 slides in the slide groove 15 through the slider 16 at this time, and the moving block 17 then drives the card plate 18 to move until the card plate 18 blocks the nut 14. At this time, the bolt 13 can be prevented from loosening, thereby improving the firmness of the bolt 13 and avoiding accidental falling off.
