The self-cleaning grid device is composed of a power unit, a frame, a pear-shaped rake tooth, a cleaning mechanism, and an electric control box.

Working principle of self-cleaning grille: 

When running, the lower part of the rake tooth chain is immersed in water. Driven by the power unit, the rake tooth chain performs a rotary motion to separate the debris in the liquid. When it runs to the upper part, due to the guide of the sprocket and the curved rail The function is to produce relative movement between the Meizu rake teeth, most of the solid debris fall off by its own weight, and the other part of the debris sticking to the rake is cleaned by rubber brushes and washed by pressure washing water.
