[0024] The functional mechanism 4 includes a cleaning component 41 and a grille component 42 . The cleaning component 41 is disposed at the top and inside of the cleaning chamber 1 , and the grille component 42 is engaged with the outside of the cleaning component 41 .

[0025] Furthermore, the cleaning component 41 includes a rotating shaft 411, a water spray cage 412, a water spray port 413 and a rolling cage 414. The top and bottom ends of the inner wall of the cleaning chamber 1 are rotatably connected with the rotating shaft 411, and the rotating shaft 411 passes through the top of the cleaning chamber 1. The outer side of the rotating shaft 411 is sleeved with a water spray cage 412, and the outer side of the water spray cage 412 is sleeved with a water spray port 413. A rolling cage 414 is arranged on the outer side of the water spray cage 412. The rolling cage 414 and the rotating shaft 411 are clamped. The rotating shaft 411 is connected to an external motor, and the rotating shaft 411 is driven by the motor to drive the rotating shaft 411, and then drive the rolling cage 414 to rotate, so that the grille component 42 moves, and the water spray port 413 at the water spray cage 412 sprays water, thereby flushing away the garbage on the surface of the grille knife 421, and completing the cleaning of the grille component 42.

In the first step, water flows through the grille assembly 42, and the hooks on the surface of the grille blade 421 complete the capture and interception of pollutants. In the second step, after a certain amount of pollutants are removed from the surface of the grille assembly 42, the operator starts the machine, and the motor drives the rotating shaft 411 to work to complete the collection of the grille assembly 42. In the third step, start the water spray cage 412, and high-pressure water is sprayed from the water spray port 413 to flush the pollutants on the surface of the grille blade 421. In the fourth step, the pollutants fall into the recovery chamber 2 under the dual action of water flow and gravity. In the fourth step, the staff retracts the roller shutter 3 and recycles the pollutants inside the recovery chamber 2. In this way, the use process of a sewage interception grille for environmental protection engineering is completed.
