Device for cleaning indoor ceiling lamps in batches

The invention discloses a device for cleaning indoor ceiling lamps in batches. The device comprises a case, and a fixing groove fixed to the indoor top wall is formed in the upper side of the case. Symmetrical wheel cavities are formed in the left side and the right side of the fixing groove. A pulley shaft extending into the wheel cavities is rotationally connected to the case. A pulley is fixedly arranged on the pulley shaft extending into the wheel cavities. The pulley can enable the case to move back and forth along the fixing groove. A moving device capable of driving the pulley shaft torotate to drive the case to move back and forth is arranged in the case. Compared with a traditional ceiling lamp cleaning mode, firstly, the device is driven by a motor, and labor is saved; secondly,the device can clean a plurality of ceiling lamps which are distributed linearly; and thirdly, a cleaning plate is mounted on the lower side of a soft belt and can be wound on a disc together with the soft belt, so that the d
