[0040] like Figure 3 and 6 As shown, a spherical valve ball 41 is movably arranged in the water passage chamber 35. When the spherical surface of the valve ball 41 abuts against the lower edge of the upper inlet 34, the valve ball 41 closes the upper inlet 34 to restrict the flow of water.

[0045] The detailed working process of this embodiment is as follows:

[0046] S1: When it rains, rainwater mixed with mud and stones passes through the rainwater inlet 24 and falls into the sedimentation tank 17. When the rainfall is small, the rainwater mixed with mud and stones will settle in the sedimentation tank 17. The mud and small stones will settle in the sedimentation tank 17. The relatively clean rainwater on the upper part will enter the groove 18 after being filtered by the primary filter 20. Then the rainwater falls downward under the action of gravity and enters the sedimentation chamber 11.

[0047] S2: Rainwater is precipitated again in the sedimentation chamber 11. The relatively clean rainwater in the upper part of the sedimentation chamber 11 is filtered by the secondary filter 29 and then enters the water storage chamber 12. When the vegetation needs to be sprinkled, the sprinkler pump 49 extracts water from the water storage chamber 12 through the water inlet pipe 50. The water extracted by the sprinkler pump 49 passes through the water delivery pipe 51 and the riser 52 in turn and is sprayed to the surrounding area through the atomizing nozzle 53;

[0048] S3: When the water in the sedimentation chamber 11 reaches the preset water level, the gravity of the water and sediment acts on the valve ball 41, causing the valve ball 41 to move downward, and the reset spring 45 is compressed. At this time, the spherical surface of the valve ball 41 is separated from the lower edge of the upper inlet 34, and the sediment and water at the bottom of the sedimentation chamber 11 enter the water chamber 35 through the upper inlet 34, and then the sediment and water pass through the lower outlet 37 and the sewage inlet 47 in turn and enter the sewage pipe 46, and the sediment and water will be discharged along the sewage pipe 46.

[0049] The green ecological slope protection structure utilizes rainwater resources to irrigate vegetation by setting up a multi-stage filtering pool 9, a water inlet pipe 50, a sprinkler pump 49, a water delivery pipe 51, a vertical pipe 52, and an atomizing nozzle 53, which is beneficial to saving water resources.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
