The upper rod body 3021 and the lower rod body 3022 are detached from the bent rod 301 and the grounding bus end 303, and then the conductive grounding rod body 302 is moved out, so as to avoid wear of the contact positions of the upper and lower ends and affect the subsequent use. When a new set of conductive grounding rod bodies 302 moves between the bent rod 301 and the grounding bus end 303, the upper rod body 3021 and the lower rod body 3022 are moved toward the side away from each other and docked with the upper and lower ends. The driving assembly 15 includes a driving rod 151, a driving gear disc 152, a driving motor 153 and a driving gear ring 154. The rod 151 is rotatably arranged in the sliding groove 14 and passes through the upper and lower groups of extension plates 922. The first reciprocating spiral groove 16 is arranged on the circumferential outer walls on the upper and lower sides of the driving rod 151. The extension plate 922 is provided with a plate hole for the driving rod 151 to pass through. The plate hole is provided with a first guide block 17 that slides with the first reciprocating spiral groove 16. The bottom of the driving rod 151 passes through the annular base 4. A linkage toothed disc 18 is fixed to the bottom end of the driving rod 151. The driving gear ring 154 is rotatably arranged at the bottom of the annular base 4. The teeth on the inner circumference of the driving gear ring 154 are meshed and connected with the linkage toothed discs 18 at the bottom of all the driving rods 151. The driving electric The motor 153 is fixed on the annular base 6. A hidden groove is provided on the annular base 6 for hiding the power supply motor to prevent the motor from protruding above the annular base 6. The output end of the driving motor 153 extends to the lower end of the annular base 4 and is fixedly connected to the driving gear disc 152. The driving gear disc 152 is meshedly connected with the driving gear ring 154. The driving motor 153 drives the driving gear disc 152 to rotate, which can drive the driving gear ring 154 to rotate, thereby driving each set of linkage gear discs 18 to rotate, and driving the driving rod 151 to rotate, and driving the extension plate 922 to move up and down through the cooperation of the first guide block 17 and the first reciprocating spiral groove 16.

[0024] See also Figure 5 , 910. In order to drive the driving gear disc 152 to rotate forward and reversely through the driving motor 153 to realize the rotation of the annular base 6 and the up and down movement of the driving extension plate 922, an inner gear ring 19 is coaxially provided at the bottom of the annular base 4. The inner gear ring 19 is rotatably arranged at the bottom of the annular base 4. The teeth on the circumferential outer wall of the inner gear ring 19 are meshed and connected with the driving gear disc 152. A first one-way bearing 20 is connected between the inner gear ring 19 and the annular base 4. The inner gear ring 19 is rotatably arranged at the bottom of the annular base 4 through the first one-way bearing 20. An outer bearing 21 is connected between the driving gear ring 154 and the bottom of the annular base 4. The ring 154 is rotatably arranged at the bottom of the annular base 4 through the outer bearing 21, and a second one-way bearing 22 is arranged between the annular base 6 and the annular base 4. The annular base 6 is rotatably arranged at the bottom of the annular base 4 through the second one-way bearing 22, wherein the direction in which the first one-way bearing 20 allows the inner gear ring 19 to rotate is the same as the direction in which the second one-way bearing 22 allows the annular base 6 to rotate (both can only rotate clockwise). When the driving gear disc 152 rotates clockwise, since the inner gear ring 19 cannot rotate counterclockwise, the motor and the annular base 6 will rotate clockwise. In addition, the annular base 6 is interference-fitted with the ring The bottom of the annular base 4, the inner gear ring 19 is also interference-fitted with the bottom of the annular base 4, and the force required to drive the annular base 6 to rotate is greater than the force to simultaneously drive the inner gear ring 19 and the driving gear ring 154 to rotate. When the driving toothed disc 152 rotates counterclockwise, the annular base 6 will not rotate, the inner gear ring 19 will rotate clockwise, and the driving gear ring 154 will rotate counterclockwise. The counterclockwise rotation of the driving gear ring 154 will drive the linkage toothed disc 18 to rotate, so that the extension plate 922 can be driven up and down by the driving rod 151. It should be noted that: in order to rotate the driving gear ring 154 clockwise When the linkage gear plate 18 is driven to rotate, the extension plate 922 will not move up and down. A third one-way bearing 23 is connected between the drive rod 151 and the linkage gear plate 18. When the drive gear ring 154 rotates clockwise to drive the linkage gear plate 18 to rotate counterclockwise, the linkage gear plate 18 cannot drive the drive rod 151 to rotate under the action of the third one-way bearing 23, thereby unable to drive the extension plate 922 to move up and down. When the drive gear ring 154 rotates counterclockwise to drive the linkage gear plate 18 to rotate counterclockwise, the drive rod 151 will rotate with the linkage gear plate 18, thereby driving the extension plate 922 to move up and down.

[0029] See also Figure 1-10 When the device is in use, when the conductive grounding rod body 302 needs to be replaced after a period of use, the drive motor 153 is started, and the drive motor 153 is started and drives the drive gear plate 152 to rotate counterclockwise. The counterclockwise rotation of the drive gear plate 152 will drive the drive gear ring 154 to rotate counterclockwise. The counterclockwise rotation of the drive gear ring 154 will drive the linkage gear plate 18 to rotate counterclockwise, thereby driving the drive rod 151 to rotate. Under the cooperation of the first guide block 17 and the first reciprocating spiral groove 16, the upper and lower extension plates 922 will be driven to move toward the side close to each other, so that the upper rod body 3021 and the lower rod body 3021 are close to each other. 022 moves toward the side approaching each other, so that the conductive grounding rod body 302 of the notch area 8 is separated from the bent rod 301 and the grounding bus end 303, and when the upper rod body 3021 and the lower rod body 3022 in the notch area 8 slide relative to each other, the upper rod body 3021 and the lower rod body 3022 located in the isolation cleaning chamber 10 will also slide relative to each other, and with the cooperation of the third guide block 36 and the spiral groove 37 and the first synchronous tooth 351 and the second synchronous tooth 352, the upper rod body 3021 and the lower rod body 3022 will rotate during the relative sliding process, thereby obtaining better cleaning of the cleaning brush 11.

[0030] After the conductive grounding rod body 302 of the notch area 8 is separated from the bent rod 301 and the grounding busbar end 303, the driving motor 153 drives the driving toothed disc 152 to rotate clockwise. Since the inner toothed ring 19 cannot rotate counterclockwise, the clockwise rotation of the driving toothed disc 152 will drive the annular base 6 to rotate clockwise. At this time, the driving toothed ring 154 will follow the clockwise rotation. Under the action of the third one-way bearing 23, the driving toothed ring 154 drives the linkage toothed disc 18 to rotate, which will not drive the driving rod 151 to rotate. The rotation of the annular base 6 will drive the conductive grounding rod body 302 of the notch area 8 to enter the isolation cleaning chamber 10 from the inlet end of the annular base 4, and at the same time drive the isolation cleaning chamber 10 to rotate. A group of conductive grounding rod bodies 302 in the chamber 10 move from the outlet end to the notch area 8, and then the driving motor 153 drives the driving gear plate 152 to rotate counterclockwise again. At this time, with the cooperation of the first guide block 17 and the first reciprocating spiral groove 16, the upper rod body 3021 and the lower rod body 3022 will be driven again to move toward the side away from each other and dock with the bent rod 301 and the grounding bus end 303 respectively. Each time the conductive grounding rod body 302 docks with the notch area 8 or the conductive grounding rod body 302 in the notch area 8 is separated from the notch area 8, the upper rod body 3021 and the lower rod body 3022 in the isolation cleaning chamber 10 will move and rotate and perform a cleaning.
