The embodiments of the present invention will be described below according to its overall structure.

[0033] Please refer to Figures 1 to 8 , in the embodiment of the present invention, a sedimentation device for a waterworks with a water intake and filtration structure includes a sedimentation tank 1. A honeycomb inclined tube filler 2 is installed at the bottom end of the inner wall of the sedimentation tank 1. A water inlet pipe 3 and a water outlet pipe 4 are respectively fixedly connected to both ends of the sedimentation tank 1. A U-shaped water collecting pipe 5 is fixedly connected to one end of the inner wall of the sedimentation tank 1. The water collecting pipe 5 is communicated with the water outlet pipe 4. The water entering the water collecting pipe 5 is filtered by a water intake and filtration mechanism 6.

[0034] The water intake and filtration mechanism 6 includes a water intake 601 and a baffle 602. The water intake 601 is opened at the top of one side of the collecting pipe 5. The baffle 602 is slidably connected to the inside of the collecting pipe 5 and extends into the inner wall of the water intake 601. A cross plate 603 is fixedly connected to the top of the collecting pipe 5 at the top of the water intake 601. Fixed blocks 604 are symmetrically and slidably connected to both sides of the water intake 601 inside the collecting pipe 5. A first spring 605 is connected between the fixed blocks 604 and the collecting pipe 5. Fixed grooves 606 are symmetrically opened on the outer walls of both sides of the baffle 602. A connecting groove 607 is opened on the outer wall of one end of the baffle 602. A connecting block 608 is slidably connected to the inner wall of the connecting groove 607. A filter frame 609 is fixedly connected to one end of the connecting block 608. The height of the baffle 602 is adjusted by an adjusting mechanism 7. The water intake and filtration mechanism 6 further includes a pushing frame 610. The pushing frame 610 is slidably connected to the inside of the baffle 602. Both ends of the pushing frame 610 respectively extend into the inner cavities of the connecting groove 607 and the fixed groove 606. A positioning groove 611 is opened at the top of the connecting block 608. A positioning block 612 that extends into the inner cavity of the connecting groove 607 is slidably connected to the inside of the baffle 602.

[0036] When installing the filter box 609, insert the connecting block 608 into the connecting slot 607. At this time, the connecting block 608 contacts the pushing frame 610, pushing the pushing frame 610 to displace. The displacement of the pushing frame 610 contacts the fixed block 604, pushing the fixed block 604 to move out of the fixed slot 606, canceling the fixation of the baffle 602. Then, through the cooperation of the parts in the adjusting mechanism 7, move the baffle 602 downward. The baffle 602 moves and separates from the cross plate 603. The positioning block 612 is engaged into the positioning slot 611 under the elastic force of the second spring 613 to fix the connecting block 608, thereby fixing the filter box 609, facilitating the filtration operation of the water entering the water collecting pipe 5, and facilitating the replacement and cleaning of the filter box 609. And when replacing, close the water intake 601 to prevent water from entering the water collecting pipe 5 without passing through the filter, and when the water intake 601 is opened, prevent the filter box 609 from loosening and affecting the filtration.

5. The settling device for a waterworks with a water intake and filtration structure according to claim 1, 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).

6. A settling device for a waterworks with a water intake and filtration structure according to claim 1, 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).

7. A settling device for a waterworks with a water intake and filtration structure according to claim 2, 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).

8. The settling device for a waterworks with a water intake and filtration structure according to claim 2, 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.

9. A method for using a settling device for a waterworks with a water intake and filtration structure according to any one of claims 1 to 8, 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.
