[0071] The dust suction duct 4 is fixedly connected to the side wall of the fixing plate 10 , and the dust suction duct 4 is communicated with the fixing plate 10 .

[0072] One end of the dust collecting barrel 8 passes through the partition 16 and is fixedly connected to the first driving motor 17. A connecting rod 18 is fixedly connected to the output shaft of the first driving motor 17. The fan blade 5 is fixedly connected to the circumferential wall of the connecting rod 18. Ventilation holes are provided on the top and bottom of the box body 1. The ventilation holes are not only convenient for the heat dissipation of the first driving motor 17, but also convenient for the fan blade 5 to discharge the air in the dust collecting barrel 8 to the outside. A dustproof net 44 is fixedly connected to the inner wall of the dust collecting barrel 8. The dustproof net 44 can prevent dust in the dust collecting barrel 8 from entering the box body 1, thereby preventing dust from affecting the heat dissipation of the first driving motor 17.

[0073] Among them, one end of the dust collecting barrel 8 is open, and the other end of the dust collecting barrel 8 is provided with a circular through hole 19, the fan blade 5 is located in the circular through hole 19, and a fixed block is fixedly connected to the outer wall of the dust collecting barrel 8 through an L-shaped rod, and the first drive motor 17 is fixedly connected to the fixed block, and the first drive motor 17 is located between the fixed block and the dust collecting barrel 8.

[0074] The dust cleaning mechanism includes an annular rotating plate 20, which is rotatably connected to the inner side wall of the dust collecting barrel 8. At least two arc plates 21 are fixedly connected to the side wall of the annular rotating plate 20. The outer arc wall of the arc plate 21 fits the inner ring wall of the dust collecting barrel 8. A slider is fixedly connected to the outer ring wall of the annular rotating plate 20. An annular groove is provided on the inner ring wall of the dust collecting barrel 8. The slider is slidably connected in the annular groove to facilitate the annular rotating plate 20 to be rotatably connected to the dust collecting barrel 8. The two ends of the arc plate 21 are inclined. In the process of the annular rotating plate 20 driving the arc plate 21 to rotate, the arc plate 21 scrapes off the dust attached to the inner wall of the dust collecting barrel 8.

[0075] The scraper 22 is fixedly connected to the inner wall of the dust collecting barrel 8, and the lower surface of the scraper 22 contacts the inner arc wall of the arc plate 21. In the process of the annular rotating plate 20 driving the arc plate 21 to rotate, the scraper 22 scrapes the dust on the arc plate 21 to one side, so that part of the dust falls downward into the connecting pipe 7, thereby facilitating the discharge of the dust in the dust collecting barrel 8.

[0076] The inner gear ring 23 is rotatably connected to the inner ring wall of the dust collecting barrel 8 , and the inner gear ring 23 is fixedly connected to one end of the arc plate 21 .

[0077] A driving rod 24 is rotatably connected to the side wall of the dust collecting barrel 8 , an incomplete gear 25 is fixedly connected to the driving rod 24 , the incomplete gear 25 is meshed with the inner gear ring 23 , and a gear 26 is fixedly connected to the driving rod 24 .

[0078] A driving plate 27 is fixedly connected to the connecting rod 18, and the driving plate 27 is meshed with the gear 26. The driving plate 27 drives the gear 26 to rotate intermittently, and the gear 26 drives the driving rod 24 to rotate intermittently. During the rotation of the driving rod 24, the inner gear ring 23 is driven to rotate intermittently, and the arc plate 21 and the annular rotating plate 20 are driven to rotate through the inner gear ring 23, thereby reducing the rotation speed of the annular rotating plate 20, so that the upper port of the connecting pipe 7 is intermittently opened, which is convenient for discharging the dust in the dust collecting barrel 8 into the connecting pipe 7.

[0079] The connecting pipe 7 is fixedly connected to the bottom of the dust collecting cylinder 8 , and the upper end of the connecting pipe 7 is flush with the inner ring wall of the dust collecting cylinder 8 .

[0080] The side wall of the cover plate 2 is provided with a receiving groove 28 , which cooperates with the dust suction pipe 4 and the power detection probe 3 , and both the dust suction pipe 4 and the power detection probe 3 are located in the receiving groove 28 .

[0081] A water-absorbing sponge 29 is fixedly connected to the side wall of the cover plate 2. The water-absorbing sponge 29 is in contact with the digital mark 37. The water-absorbing sponge 29 is used to apply stamp ink on the digital mark 37. When the cover plate 2 is closed on the box body 1, the digital mark 37 is in contact with the water-absorbing sponge 29, and the stamp ink absorbed in the water-absorbing sponge 29 adheres to the digital mark 37. When the digital mark 37 is in contact with the power equipment, the digital mark 37 copies the stamp ink on the power equipment, thereby marking the test and maintenance parts of the power equipment, which is convenient for the staff to find the faulty parts of the power equipment in time.

[0082] Working principle: When it is necessary to test and repair the power equipment, the staff will rotate the cover plate 2 upwards. At this time, through the elastic force of the first spring 15, the first spring 15 pushes the connecting plate 12 to the outside of the box body 1, and drives the dust collection pipe 4, the power detection probe 3 and the digital mark 37 to move to the outside of the box body 1. Since the dust collection pipe 4 is a bellows, the dust collection pipe 4 is in a stretched state at this time. At the same time, the length of the wire between the connecting plate 12 and the fixed plate 10 on the power detection probe 3 is equal to the length of the dust collection pipe 4 in the stretched state, which is convenient for the power detection probe 3 to test the power equipment. Then the box body 1 is placed on one side of the power equipment, so that the power detection probe 3 can detect the wiring port of the power equipment. The power detection probe 3 transmits the detection result to the display screen 9 through the wire and displays it on the display screen 9. When the power detection probe 3 tests the power equipment, the digital mark 37 is in contact with the surface of the power equipment and is located on one side of the power detection probe 3, thereby marking the part detected by the power detection probe 3. When the power detection probe 3 detects the faulty part of the power equipment, it is displayed on the display screen 9. The staff can determine the faulty part of the power equipment through the part marked by the digital mark 37 corresponding to the display screen 9 showing the fault, thereby facilitating the staff to troubleshoot the faulty part on the power equipment and saving the staff's time for testing and repairing the power equipment.

[0083] During the process of the power detection probe 3 testing and repairing the power equipment, the first drive motor 17 is turned on, and the output shaft of the first drive motor 17 drives the connecting rod 18 and the fan blade 5 to rotate. The fan blade 5 sucks the dust on the surface of the power equipment into the dust collecting cylinder 8 through the dust suction pipe 4, thereby reducing the dust attached to the surface of the power equipment and avoiding the staff from manually cleaning the dust on the power equipment. In the process of the first drive motor 17 driving the connecting rod 18 to rotate, the connecting rod 18 drives the gear 26 to rotate intermittently through the drive plate 27, and the drive gear 26 drives the drive rod 24 to rotate, and when the drive rod 24 rotates During the process, the inner gear ring 23 is driven to rotate intermittently through the meshing of the incomplete gear 25 and the inner gear ring 23, and the arc plate 21 and the annular rotating plate 20 are driven to rotate. During the rotation of the arc plate 21, the arc plate 21 pushes the dust on the inner ring wall of the dust collecting barrel 8 in the rotation direction of the arc plate 21. When the arc plate 21 rotates and disengages from the upper port of the connecting pipe 7, the upper port of the connecting pipe 7 is in an open state, so that the arc plate 21 can push the dust on the inner ring wall of the dust collecting barrel 8 into the connecting pipe 7, and make the dust slide into the dust exhaust pipe 6 through the connecting pipe 7, and then be discharged through the dust exhaust pipe 6.

[0084] In the process of the inner gear ring 23 driving the arc plate 21 to rotate, when the arc plate 21 contacts the scraper 22, the scraper 22 will scrape one side of the dust attached to the inner arc wall of the arc plate 21 during the rotation of the arc plate 21, wherein the scraper 22 is located directly above the connecting pipe 7. When the arc plate 21 rotates to one side of the connecting pipe 7, the scraper 22 will scrape the dust on the inner arc wall of the arc plate 21 away from the arc plate 21, and part of the scraped dust will slide into the connecting pipe 7 through the upper port of the connecting pipe 7, thereby realizing the discharge of dust in the dust collecting barrel 8.

When the moving block 32 pushes the circular block 35 in the direction of the rotating shaft 40 and the card plate 41 is inserted into the card slot 42, the arc-shaped through hole 34 is located between the circular block 35 and the moving block 32. When the rotating shaft 40 rotates, it drives the circular block 35 and the cleaning plate 43 to rotate, and the cleaning plate 43 scrapes the dust on the moving block 32, and the scraped dust slides out of the dust treatment pipe 30 through the arc-shaped through hole 34.

[0090] Among them, an annular groove 38 is opened on the side wall of the circular block 35, and a sliding block 39 is slidably connected in the annular groove 38. One end of the second spring 36 is fixedly connected to the sliding block 39, and a telescopic tube is sleeved on the outside of the second spring 36. The length value of the telescopic tube in the contracted state is consistent with the length value of the second spring 36 in the contracted state, and the length value of the telescopic tube in the extended state is consistent with the length value of the second spring 36 in the extended state, thereby preventing the circular block 35 from driving the second spring 36 to rotate during the rotation process.

[0091] A second drive motor 33 is fixedly connected to the outer wall of the box body 1, and the output shaft of the second drive motor 33 passes through the side wall of the box body 1 and is fixedly connected to the end of the screw 31. The second drive motor 33 is a prior art, and the second drive motor 33 and the first drive motor 17, and the wires on the display screen 9 are electrically connected to the power storage device in the prior art, and the output of the second drive motor 33 can achieve forward and reverse rotation. The output shaft of the second drive motor 33 is fixedly connected to one of the rotating shafts 40, and the output shaft of the second drive motor 33 drives the moving block 32 to move horizontally through the screw 31. When the moving block 32 pushes the circular block 35 toward the direction of the card plate 41 and inserts the card plate 41 into the card slot 42, the output shaft of the second drive motor 33 drives the screw 31 to rotate in the opposite direction, thereby driving the moving block 32 to move back through the screw 31.

[0092] Working principle: the arc plate 21 pushes the dust in the dust collecting barrel 8 into the connecting pipe 7, so that the dust in the connecting pipe 7 slides downward through the dust exhaust pipe 6 to the dust processing pipe 30, and the second drive motor 33 is started. The output shaft of the second drive motor 33 drives the rotating shaft 40 and the lead screw 31 to rotate. During the rotation of the lead screw 31, the movable block 32 is driven to move horizontally by the restriction of the thread. The movable block 32 pushes the dust at the bottom of the dust processing pipe 30 to one side. When the movable block 32 contacts the circular block 35, the lead screw 31 continues to drive the movable block 32 to move. The movable block 32 pushes the circular block 35 in the direction of the card plate 41, and due to the elastic force of the second spring 36, the second spring 36 pushes the circular block 35 in the direction of the movable block 32. At this time, the movable block 32 and the circular block 35 push each other, thereby squeezing the dust between the movable block 32 and the circular block 35 into blocks, so as to facilitate the dust to be discharged from the dust processing pipe 30 in blocks, and avoid the dust from flying around in the falling process when the dust is in a loose state.

[0093] When the card plate 41 is inserted into the card slot 42, the circular block 35 is located on one side of the arc-shaped through hole 34. At the same time, the rotation of the rotating shaft 40 drives the rotation of the circular block 35. The cleaning plate 43 on the circular block 35 scrapes off the dust attached to the moving block 32, and the scraped dust slides down through the arc-shaped through hole 34 to the outside of the box body 1. A through hole matching the arc-shaped through hole 34 is opened at the bottom of the box body 1 to facilitate the discharge of dust in the dust treatment pipe 30.

[0094] When the rotating shaft 40 drives and the card plate 41 is fully inserted into the card slot 42, at this time, the output shaft of the second drive motor 33 drives the rotating shaft 40 and the screw 31 to rotate in the opposite direction, and the screw 31 drives the moving block 32 to move back through the limitation of the thread. In the process of the moving block 32 moving back, the dust that continues to fall in the dust exhaust duct 6 is pushed toward the other end of the screw 31, and the moving block 32 and the circular block 35 at the other end of the screw 31 squeeze the dust into blocks, thereby facilitating the discharge of dust in the dust treatment duct 30 in blocks, and preventing the dust from flying around when discharged in a loose state.
