DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example 1: Please refer to Figure 1 - Figure 5 A dust removal device for a surveillance camera of the present embodiment includes a base 1 and a transparent ball cover 2. A fixed ring 4 is fixedly connected to the top of the base 1. A rotating ring 5 is movably connected to the top of the fixed ring 4. A motor 8 is arranged inside the base 1. A rotating shaft 9 is fixedly connected to the top of the motor 8. A gear 10 is fixedly connected to the top of the rotating shaft 9. An inner gear ring 11 is meshingly connected to one side of the gear 10. The inner gear ring 11 is movably connected to the inside of the fixed ring 4. The top of the inner gear ring 11 is fixedly connected to the bottom of the rotating ring 5.

[0025] When dust accumulates on the surface of the transparent ball cover 2 and needs to be cleaned, the motor 8 is started, the motor 8 will drive the rotating shaft 9 to rotate, the rotating shaft 9 will drive the gear 10 to rotate, the gear 10 will drive the inner gear ring 11 to rotate, the inner gear ring 11 will drive the rotating ring 5 to rotate, and the rotating ring 5 will drive the rotating rod 6 to rotate along the outside of the transparent ball cover 2, so as to facilitate the cleaning of the dust on the surface of the transparent ball cover 2;

[0026] Among them, one end of the rotating ring 5 is fixedly connected to a rotating rod 6, a brush 7 is arranged on the inner side of the rotating rod 6, and the brush 7 is movably connected to the outer surface of the transparent ball cover 2. Two slots 20 are processed inside the rotating rod 6, and two plug blocks 19 are fixedly connected to the outside of the brush 7. The plug blocks 19 are plug-connected inside the slots 20. The transparent ball cover 2 is located at the top of the rotating ring 5. A camera 3 is arranged inside the transparent ball cover 2. A groove is processed on the top of the plug block 19, and the bottom of the limit block 21 is plug-connected inside the groove.

[0027] When the brush 7 needs to be replaced and cleaned after being used for a long time, the limit block 21 is separated from the inside of the plug block 19, so that the brush 7 can be moved laterally, so that the brush 7 drives the plug block 19 to be separated from the inside of the slot 20, so as to facilitate the cleaning and replacement of the brush 7;

[0028] Since the two plug-in blocks 19 connected to the outside of the brush 7 are plugged into the inside of the rotating rod 6, and the two plug-in blocks 19 are tilted to each other to form a certain angle, the brush 7 cannot fall when it is on the inside of the rotating rod 6, which plays a limiting role for the brush 7;

[0029] Furthermore, the outer part of the inner gear ring 11 is fixedly connected with a limit ring 12, and a limit groove 13 is processed on the inner side of the fixed ring 4. The limit ring 12 is movably connected inside the limit groove 13. When the gear 10 drives the inner gear ring 11 to rotate, the inner gear ring 11 will drive the limit ring 12 to rotate, and the limit ring 12 will rotate along the inner part of the limit groove 13. By providing the limit ring 12, the movement of the inner gear ring 11 is limited, and the movement of the rotating ring 5 is limited by the inner gear ring 11.

[0030] Furthermore, the top of the rotating rod 6 is fixedly connected with a movable shaft 14, and the bottom of the movable shaft 14 is rotatably connected to the top of the transparent ball cover 2. When the rotating ring 5 drives the rotating rod 6 to rotate, the rotating rod 6 will drive the movable shaft 14 to rotate, and the bottom of the movable shaft 14 will rotate along the top of the transparent ball cover 2.

[0031] Further, a movable groove 17 is processed inside the rotating rod 6, and a connecting block 16 is movably connected inside the movable groove 17. One end of the connecting block 16 is fixedly connected to a movable block 15. The movable block 15 is located on one side of the rotating rod 6. The bottom of the connecting block 16 is fixedly connected to a limiting block 21, and the bottom of the limiting block 21 is movably connected to the inside of the slot 20.

[0032] When the brush 7 needs to be replaced, the movable block 15 is pushed upward, the movable block 15 will drive the connecting block 16 to move, and the connecting block 16 will drive the limiting block 21 to move, so that the limiting block 21 is separated from the top groove of the inserting block 19, so that the brush 7 can be moved horizontally, so that the inserting block 19 is separated from the inside of the slot 20, and the brush 7 is convenient to remove;

[0033] Furthermore, a return spring 18 is provided inside the movable groove 17, one end of the return spring 18 is fixedly connected to the top inner wall of the movable groove 17, and the other end of the return spring 18 is fixedly connected to the top of the connecting block 16. When the movable block 15 is pushed upward, the movable block 15 will drive the connecting block 16 to move, and the connecting block 16 will compress the return spring 18. When the movable block 15 is released, the return spring 18 will reset and extend, pushing the connecting block 16 and the slot 20 to move, so that the slot 20 is inserted into the top groove of the insertion block 19.

[0034] Working principle: By starting the motor 8, the motor 8 will drive the rotating shaft 9 to rotate, the rotating shaft 9 will drive the gear 10 to rotate, the gear 10 will drive the inner gear ring 11 to rotate, the inner gear ring 11 will drive the rotating ring 5 to rotate, and the rotating ring 5 will drive the rotating rod 6 to rotate along the outside of the transparent ball cover 2, so as to facilitate the cleaning of the dust on the surface of the transparent ball cover 2. By pushing the movable block 15 upward, the movable block 15 will drive the connecting block 16 to move, and the connecting block 16 will drive the limit block 21 to move, so that the limit block 21 is disengaged from the top groove of the plug block 19, so that the brush 7 can be moved laterally, so that the plug block 19 is disengaged from the inside of the slot 20, so as to facilitate the removal of the brush 7 for cleaning and replacement.
