[0027] Embodiment: Refer to Figures 1-3 A power cable trench cleaning and maintenance device shown, including a mounting plate 1, a motor 2 is installed on the mounting plate 1, a plurality of universal wheels 4 are installed at the lower end of the mounting plate 1, a mounting plate 6 is installed below the mounting plate 1 through a transmission member, and the motor 2 drives the mounting plate 6 to rotate through a transmission member;

[0028] At the lower end of the mounting disc 6, there are a plurality of movable cleaning brushes 7 that are slidably connected through connecting members and are circumferentially arrayed along the axis of the mounting disc 6. The movable cleaning brushes 7 slide radially along the mounting disc 6;

[0029] At the upper end of the mounting disc 6, a first fastening bolt 8 is also installed. The first fastening bolt 8 is used to fix the movable cleaning brush 7 so that the movable cleaning brush 7 is fixed to the mounting disc 6.

[0030] Based on the above structure, during use, the staff can pull the movable cleaning brush 7, causing the movable cleaning brush 7 to slide radially along the mounting disc 6, thereby adjusting the position of the movable cleaning brush 7. After adjustment, the cleaning range formed by the plurality of movable cleaning brushes 7 changes, thereby expanding or shrinking the cleaning range of the power cable trench cleaning and maintenance device, and is used to complete the cleaning operation of cable trenches with different widths. Good usage effects are achieved during actual use, expanding the applicable range of the power cable trench cleaning and maintenance device. After adjustment, the movable cleaning brush 7 can be limited by the first fastening bolt 8, making the movable cleaning brush 7 fixed to the mounting disc 6, thereby fixing the cleaning range during use and avoiding changes in the range caused by the movement of the movable cleaning brush 7.

[0031] Further, the connecting member includes a slider 9, and the slider 9 is fixed to the upper end of the movable cleaning brush 7;

[0032] A chute 10 is formed on the bottom surface of the mounting disc 6, and the slider 9 is slidably connected within the chute 10;

[0033] The lower end of the first fastening bolt 8 threadedly penetrates through the first fastening bolt 8 and abuts against the upper end of the slider 9.

[0034] Through the arrangement of the slider 9 and the chute 10, the movable cleaning brush 7 can be slidably installed on the mounting disc 6, thus meeting the requirement of adjusting the cleaning range of the movable cleaning brush 7 to expand or shrink. At the same time, when the lower end of the first fastening bolt 8 abuts against the slider 9, it can also limit the movable cleaning brush 7, thus meeting the requirement of fixing the range of the movable cleaning brush 7.

[0035] Further, a first spring 11 is fixed to the inner side wall of the chute 10 close to the axis of the mounting disc 6, and the other end of the first spring 11 is fixed to the side of the slider 9 close to the axis of the mounting disc 6. Through the arrangement of the first spring 11, according to actual usage requirements, the limit of the first fastening bolt 8 on the slider 9 can be released, so that the movable cleaning brush 7 is elastically slidably connected to the mounting disc 6. During use, the output speed of the motor 2 can be changed to change the magnitude of the centrifugal force received by the movable cleaning brush 7. When the centrifugal force is greater, the extended length of the movable cleaning brush 7 is longer, so that the cleaning range can be changed in real time during use by changing the speed, making the use more flexible and convenient.

[0036] Further, the transmission member includes a driving sleeve shaft 3 and a driven shaft 5. The driving sleeve shaft 3 is rotatably connected to the lower end of the mounting plate 1 and fixed to the output shaft of the motor 2.

[0037] The upper end of the driven shaft 5 is integrally formed with a square shaft 13, and the square shaft 13 is slidably inserted into the square groove 14;

[0038] A second fastening bolt 16 is threadedly penetrated through one side of the driving sleeve shaft 3, and one end of the second fastening bolt 16 abuts against one side of the square shaft 13;

[0039] When the motor 2 is started, the mounting disc 6 is driven to rotate through the driving sleeve shaft 3 and the driven shaft 5, so as to realize the cleaning operation. At the same time, the relative fixation or relative sliding of the driving sleeve shaft 3 and the driven shaft 5 can be achieved by screwing the second fastening bolt 16, so as to adjust the length formed by the driving sleeve shaft 3 and the driven shaft 5 for cleaning cable trenches with different depths.

[0040] Further, a second spring 15 is fixed to the inner top wall of the square groove 14, and the lower end of the second spring 15 is fixed to the top surface of the square shaft 13.

[0041] Through the arrangement of the second spring 15, after the second fastening bolt 16 releases the limit on the square shaft 13, the driving sleeve shaft 3 and the driven shaft 5 can be elastically connected, so that the driving sleeve shaft 3 and the driven shaft 5 can adaptively expand and contract according to the extrusion force (the reaction force from the bottom of the cable trench) during use, so that the cleaning and maintenance device for the power cable trench can adaptively change the cleaning depth during use and is more flexible and convenient to use.

[0042] Further, a connecting ring 12 is fixedly sleeved on the lower end of the driven shaft 5. The driven shaft 5 is detachably fixed to the upper end of the mounting disc 6 through the connecting ring 12, so that the mounting disc 6 and the movable cleaning brush 7 can be detachably replaced or maintained, which is convenient for maintaining the cleaning and maintenance device for the power cable trench and also improves the convenience of use.

[0043] Working principle of the utility model: During daily use, after the motor 2 is turned on, the motor 2 drives the mounting disk 6 to rotate through the driving sleeve shaft 3 and the driven shaft 5 for cleaning operations. Before and after the cleaning operations, the staff can pull the movable cleaning brush 7 to make the movable cleaning brush 7 slide radially along the mounting disk 6, thereby adjusting the position of the movable cleaning brush 7. After adjustment, the cleaning range formed by multiple movable cleaning brushes 7 changes, so as to expand or shrink the cleaning range of the power cable trench cleaning and maintenance device, and be used to complete the cleaning operations of cable trenches with different widths, achieving good use effects in actual use, expanding the applicable range of the power cable trench cleaning and maintenance device. After adjustment, the movable cleaning brush 7 can be limited by the first fastening bolt 8 to fix the movable cleaning brush 7 to the mounting disk 6, thereby fixing the cleaning range during use and avoiding the change of the range caused by the movement of the movable cleaning brush 7;

[0044] Meanwhile, through the setting of the first spring 11, according to actual use requirements, the limit of the first fastening bolt 8 on the slider 9 can be released, so that the movable cleaning brush 7 is elastically slidably connected to the mounting disk 6. During use, the output speed of the motor 2 can be changed to change the magnitude of the centrifugal force received by the movable cleaning brush 7. When the centrifugal force is greater, the extending length of the movable cleaning brush 7 is longer, so that the cleaning range can be changed in real time during use by changing the speed, making the use more flexible and convenient.
