A settling device for a waterworks with a water intake and filtration structure according to claim 2, characterized in that: The outer walls of the positioning block (612) and the extrusion rod (615) are both provided with tooth grooves, and the tooth grooves are meshed with the spur gear (614).

7. A settling device for a waterworks with a water intake and filtration structure according to claim 2, characterized in that: The pushing frame (610) is in a T-shape, and a second inclined surface is provided at one end of the pushing frame (610) located in the inner cavity of the connecting groove (607).

8. The settling device for a waterworks with a water intake and filtration structure according to claim 3, characterized in that: The outer wall of the rotating disk (701) is provided with gear teeth, which mesh with the bevel gear (702); a threaded hole is provided at the top of the baffle (602), which matches the threaded rod (703).

9. A settling device for a waterworks with a water intake and filtration structure according to claim 3, characterized in that: The inner wall of the slot (708) fits with the outer wall of the insert block (707); a circular hole is provided on the outer wall of the telescopic plate (706); the inner wall of the circular hole fits with the outer wall of the rotating rod (705); and the outer wall of the rotating rod (705) is fixedly connected to a limiting plate (8) on both sides of the circular hole.

10. A method for using a settling device for a water plant with a water intake and filtration structure, characterized in that: The specific steps are as follows: Step 1: Insert the connection block (608) into the connection slot (607) and then install the filter frame (609); Step 2: Rotate the rotating rod (705). The rotating rod (705) rotates through the insert block (707) to drive the rotating disk (701) to rotate. The rotating disk (701) rotates to drive the bevel gear (702) to rotate. The bevel gear (702) rotates to drive the threaded rod (703) to rotate. The threaded rod (703) rotates to drive the baffle (602) to move, and the water intake (601) is opened. At this time, the positioning block (612) is engaged into the positioning groove (611) by the elastic force of the second spring (613), and the connecting block (608) is fixed, thereby fixing the filter frame (609). Step 3: The water in the sedimentation tank (1) enters the water collecting pipe (5) through the water intake (601), and then flows into the water outlet pipe (4) through the water collecting pipe (5). When the water enters the water collecting pipe (5) through the water intake (601), the water passes through the filter frame (609), and the filter frame (609) performs a filtering operation on the water.
