When the blade 11 leaves the slide base 16, the slide base 16 is restored again by the restoring force of the strip spring piece 15. Thus, when the siphon phenomenon occurs, the bar-shaped spring piece 15 continuously dredges the siphon 4 to avoid the blockage of the siphon 4. The invention can automatically dredge the interior of the siphon 4 and prevent garbage from blocking the siphon 4. The invention utilizes the rotation of the rotating ring 10 caused by the siphonage to drive the strip-shaped spring piece 15 to continuously stretch and retract, dredges the interior of the siphon 4, prevents garbage from blocking the siphon 4, improves the drainage efficiency and is beneficial to drainage of eave 17.

As shown in figures 1 and 4, the invention is provided with two siphons 4 and a strip-shaped spring piece 15, when one siphon 4 is blocked, rainwater can enter the second siphon 4 through the rainwater hole 3, and because the two siphons 4 share the same rotating shaft 9, when the second rotating ring 10 rotates to drive the strip-shaped spring piece 15 to dredge the siphon 4 due to rainwater washing, the first rotating ring 10 also rotates and drives the strip-shaped spring piece 15 to dredge the blocked first siphon 4, so that the first siphon 4 is recovered to be unblocked, and the blockage is avoided. The invention can drive the strip-shaped spring piece 15 in the first siphon 4 to dredge the blocked siphon 4 by utilizing the rotation of the second rotating ring 10 under the condition that the single siphon 4 is blocked, so that the blocked siphon 4 is recovered smoothly, the blockage is avoided, the double insurance is realized, the rainwater can wash the garbage in the rainwater tank 1 and discharge the garbage, the structure is simple and stable, and the drainage of the eave 17 is facilitated.

The strip-shaped spring piece 15 is a bamboo strip. The bamboo strips are strong in elasticity and light in weight, and the blades 11 can be jacked up conveniently.
