detailed description

Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in detail.

In one embodiment of the present utility model, as shown in Figure 1, a kind of rainwater recovery device is provided, including the sump pool 2, filter pool 3 and water storage tank 16 that are connected as a whole; The sewage sink 14 that precipitates impurities, the water inlet pipe 1 is connected to the water pan 23 for collecting rainwater; the filter tank 3 is set above the sewage sink 14, and is connected to the water storage tank 16 through the water pipe 10; the side of the water storage tank 16 near the top An overflow pipe 17 is provided, and an irrigation device is provided at the lower end. The irrigation device includes a water outlet pipe 18, a main water valve 19 connected to the water outlet pipe, a water pump 20 and several shower heads 22 connected to the water pump.

Rainwater collects in the water tray 23 and flows into the water inlet pipe 1, the other end of the water inlet pipe 1 is perpendicular to one end of the sump 2, the other end of the sump 2 shares the wall with the filter layer pool support part 7, and the other end of the filter layer pool support part 7 One end is provided with a sinking tank 14, and above the sinking tank 14 is provided with a filter tank 3. The side of the filter tank 3 near the top is provided with a water pipe 10 connected to the water storage tank 16, and the side of the water storage tank 16 near the top is provided with an overflow The lower end of the pipe 17 is provided with an irrigation device, and the rainwater in the water storage tank 16 is sprayed out through the connection of the outlet pipe 18 with the water pump 20 and the sprinkler head 22, so as to achieve the purpose of irrigating the green space.
