Background

Gardens refer to natural environments and recreation areas which are specially cultivated, engineering technology and artistic means are applied to a certain region, and the natural environments and recreation areas are created through the means of modifying terrains, planting trees, flowers and plants, building buildings, arranging garden paths and the like.

In the construction maintenance process in gardens, need regularly water to vegetation trees etc. in order to keep the survival rate of vegetation, generally adopt running water to water, the water consumption is big, causes the water waste easily, when rainy weather, because the direct drainage sewer of rainwater flows away, very easily causes the waste of rainwater resource, although there is the cistern to store up the rainwater at present, the rainwater in the cistern can have the impurity such as leaf, silt, and the leaf putrefaction in aqueous easily probably to lead to water to give off the peculiar smell, thereby influence the environment in gardens when watering. Therefore, more and more gardens can be configured with rainwater water collection and utilization device and be used for collecting the rainwater, collect the storage through filtering the rainwater to the rainwater of collecting is utilized, in order to reach comprehensive utilization rainwater resource and water economy's purpose.

The utility model discloses a gardens rainwater collection and reuse device as disclosed in publication number CN113123426a, which can collect and filter rainwater and then reuse the rainwater, but still has the following defects in the rainwater collection and utilization process:

1. Since a large amount of sediment is carried in rainwater in the early period of raining, the rainwater is adsorbed by an active carbon filter screen in the early period, and the filter screen is easily blocked due to accumulation;

2. In the process of collecting rainwater, the dead branches and the dead leaves are accumulated at the positions of the rainwater grate along with the flowing of the rainwater, so that the attractiveness of gardens is affected;

3. Only rainwater can be simply utilized, and accumulated dead branches and the dead leaves cannot be effectively utilized.

For this reason, we propose a hierarchical treatment rainwater purification device for gardens for solving the above-mentioned problems.
