Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, not to limit the utility model.

As shown in Figure 1, in this embodiment, the rainwater collection and utilization system of the present utility model includes a gutter 2 arranged around the base of the greenhouse 1, a filter layer 5 and a soft permeable pipe arranged in the gutter 2 4, and rainwater storage tank 6, wherein,

The gutter 2 is set on the lower side of the ceiling of the greenhouse 1, the soft permeable pipe 4 is set close to the bottom of the gutter 2, the filter layer 5 is set outside the soft permeable pipe 4, and the water outlet of the soft permeable pipe 4 Connect to rainwater storage tank6.

The utility model collects the rainwater falling on the greenhouse 1 to the water collecting ditch 2 provided at the base of the lower side of the ceiling, and a filter layer 5 is arranged in the water collecting ditch 2 to filter the rainwater for the first time and filter out large volume debris, etc., and then the rainwater is filtered again through the soft permeable pipe 4. The soft permeable pipe 4 can filter out impurities such as muck in the rainwater, which can ensure the water quality of the filtered rainwater. The rainwater flows into the rainwater through the soft permeable pipe 4. storage tank6. Therefore, the utility model can utilize the greenhouse to collect and utilize rainwater, and collect rainwater with better water quality.

In order to prevent the rainwater collected by the gutter 2 from penetrating into the soil, an anti-seepage layer 3 can be laid on the gutter 2 . Then the soft permeable pipe 4 is laid on the anti-seepage layer 3, so that the rainwater collected in the gutter 2 can all enter the soft permeable pipe 4 through filtering. Further, the anti-seepage layer 3 is preferably an anti-seepage composite geomembrane.

Simultaneously in order to reduce cost, filter layer 4 of the present utility model can adopt crushed stone layer, and it is easy to obtain materials, and the effect of filtering larger particle fragments is good.

When collecting rainwater, in order to make the rainwater in the soft permeable pipe 4 smoothly flow into the rainwater storage tank 6, the gutter 2 can be provided with a slope, and the water outlet of the soft permeable pipe 4 is located at the lowest slope of the gutter 2. Further, the water collecting ditch 2 forms the lowest end of the slope at its middle position, that is, the bottom of the slope, and the water outlet of the soft permeable pipe 4 is connected to the rainwater storage tank at the middle position of the water collecting ditch 2 .

As can be seen from accompanying drawings 1 and 2, the rainwater storage tank 6 is arranged close to the gutter 2, and the rainwater storage tank 6 can be arranged at any suitable position according to different needs. In addition, the greenhouse described in the present invention can be but not limited to solar greenhouses, plastic greenhouses and other agricultural facilities and buildings, which can also be equivalently replaced with non-agricultural facilities and buildings such as outdoor equipment rooms and warehouses.

The utility model also provides a method for collecting and utilizing rainwater, the method comprising the steps of:

S10: collecting rainwater into a gutter arranged around the base of the greenhouse;

S20: Using the filter layer to filter the rainwater initially collected in the gutter;

S30: The rainwater filtered for the first time is filtered for the second time by using the soft permeable pipe, and the rainwater filtered for the second time is collected into the rainwater storage tank.

In the rainwater collection and utilization method provided by the utility model, the rainwater is initially collected in the gutter arranged around the base of the greenhouse, then passes through the filter layer and the soft permeable pipe in the gutter, and finally passes through the outlet of the soft permeable pipe It flows into the rainwater storage tank and is collected. Therefore, the utility model can utilize the greenhouse to collect rainwater, and collect rainwater with better water quality.

In order to prevent rainwater from permeating and flowing away in the gutter, the gutter has an anti-seepage effect. The rainwater collected in the gutter can all be filtered and enter the soft permeable pipe like this.

Simultaneously, in order to reduce the cost, the filter layer is a crushed stone layer, which is convenient to obtain materials and has a good effect of filtering large-volume particle fragments.
