[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a wetland water purification ecological restoration structure.

[0027] The utility model provides Figure 1-4 A wetland water purification ecological restoration structure shown includes a water retaining dam 1 and a first filter area 2, a second filter area 3 and a restoration area 4 arranged outside the water retaining dam 1. The surface of the restoration area 4 is planted with emergent plants 5. The surfaces of the first filter area 2, the second filter area 3 and the restoration area 4 are paved with a suspended interception net 6. The suspended interception net 6 is a polyethylene suspended interception net. A support frame 7 is fixedly provided on the upper end of the side wall of the water retaining dam 1. The support frame 7 is a U-shaped support frame. Rotating rods 8 are rotatably penetrated on both sides of the support frame 7. A winding roller 9 is fixedly provided between the two rotating rods 8. One end of the suspended interception net 6 is fixedly wound with the roller wall of the winding roller 9. A pull ring 16 is fixedly provided on the top of the suspended interception net 6 and at the end away from the support frame 7.

[0028] The sewage passes through the retaining dam and then through the first filter area 2 and the second filter area 3 for purification and then flows into the repair area 4 for repair. Prior to this, the suspended interception net 6 is laid above the purification area 4. Since the suspended interception net 6 is suspended on the water surface, the debris falling into the water surface can be intercepted. Thereafter, the rotating rod 8 can be rotated, and the suspended interception net 6 is wound by the rotating rod 8 and the winding roller 9. At this time, the debris on the suspended net is removed and cleaned on the retaining dam 1 to avoid impurities from infiltrating into the repair area 4 and affecting the repair work. At the same time, when the suspended interception net 6 is laid, the pull ring 16 can be set and the regional pulling component can be used to stably lay the suspended interception net 6 on the water surface.

[0029] In order to determine the location of the suspended interception net 6 and to facilitate the convenient winding of the suspended interception net 6, as shown in FIG. Figure 2-4As shown, a rotation limiting mechanism is provided between the rotating rod 8 and the supporting frame 7, and the rotation limiting mechanism includes an annular plate 10, which is fixedly arranged on the outer side of the supporting frame 7 and sleeved with the rotating rod 8. The inner wall of the annular plate 10 is provided with a plurality of positioning grooves 11 which are symmetrically arranged in a circle, and the outer wall of the rotating rod 8 is provided with a groove, and the inner wall of the groove is fixedly provided with a cross bar 12, and the rod wall of the cross bar 12 is rotatably sleeved with a positioning plate 13, and the interior of the positioning plate 13 is provided with a pulling hole 15, and the positioning plate 13 is plugged into the positioning groove 11, and both ends of the cross bar 12 are sleeved with torsion springs 14, and the two ends of the torsion spring 14 are respectively fixedly connected to the cross bar 12 and the positioning plate 13.

[0030] Before winding the suspended intercepting net 6, the positioning plate 13 can be pulled through the pulling hole 15, so that the positioning plate 13 rotates around the cross bar 12 and twists the torsion spring 14. At this time, the positioning plate 13 is pulled out from the positioning groove 11, and then the positioning plate 13 can drive the rotating rod 8 to rotate, so that the rotating rod 8 drives the winding roller 9 to rotate and wind the suspended intercepting net 6, which is convenient for collecting debris on its surface. When the suspended intercepting net 6 needs to be laid, the positioning plate 13 is loosened, and the torsion of the torsion spring 14 can make the positioning plate 13 rebound and be inserted into the positioning groove 11 again, the position of the rotating rod 8 is determined, and the winding position of the suspended intercepting net 6 can be fixed to ensure its stability in use.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
