the rotating unit 11 is connected with a connecting shaft 13 above the plate to be cleaned and is used for driving the connecting shaft 13 to rotate.

When the scraper 2 needs to be driven to move upwards, the rotating unit 11 drives the connecting shaft 13 above the ash removing plate to rotate, the connecting shaft 13 drives the top chain wheel 121 connected with the connecting shaft to rotate synchronously, under the meshing action of the top chain wheel 121, the bottom chain wheel 122 and the chain 123, the bottom chain wheel 122 drives the connecting shaft 13 below to rotate synchronously, the chain 123 rotates around the top chain wheel 121 and the bottom chain wheel 122, in the same chain wheel unit 12, the connecting line of the top chain wheel 121 and the bottom chain wheel 122 serves as a boundary, the chain 123 is divided into a first chain section and a second chain section, the first chain section moves upwards, the second chain section moves downwards, and two ends of the scraper 2 are connected to the first chain section, so that the upward movement of the scraper 2 is realized;

When the number of the plates to be cleaned is 2n, the cleaning device needs n cleaning units, and when the number of the plates to be cleaned is 2n+1, the cleaning device may include 2n+1 cleaning units of the first embodiment, or may include n cleaning units of the second embodiment, and one cleaning unit of the first embodiment, n-0,1,2, ….
