Background technique

The shortage of water resources and serious water pollution have constituted the current situation of my country's water resource crisis. In summer, our country suffers from floods in the south and drought in the north. In garden management, a large amount of irrigation is required. Irrigation of planted plants requires a large amount of water resources in irrigation. If rainwater can be used to irrigate plants, it will bring great convenience to garden irrigation and planting, which is convenient for gardening. Management, rainwater harvesting is a problem we need to face and solve.

A patented municipal garden rainwater collection and irrigation device and its collection method (application number: 201610637733.5) provides a rainwater collection and irrigation device for municipal gardens, which directly introduces rainwater from the rainwater underground channel through water pipes, and at the same time sets rainwater collection above the surface The modules are used to collect rainwater, and sprinklers are also installed for irrigation. However, it is inconvenient to clean or maintain the water tank if the water storage tank is buried underground. Separate installations for rainwater collection and irrigation increase the floor area of the device and increase the use of piping materials, which is not conducive to improving the utilization rate of resources.

Residual branches, leaves, mud, fine sand and other debris make the rainwater clean enough for irrigation. At the same time, the funnel-shaped rainwater collector is used to directly collect the rainwater that does not fall on the ground surface. The diversified collection makes the rainwater utilization rate higher. To ensure that the garden irrigation needs are met, when the rainwater storage capacity in the water storage tower reaches the maximum, the diversion well can temporarily store a part of the untreated rainwater for later use;

(2) When irrigation is required, close the valve, turn on the second water pump, and the rainwater in the water storage tower will be sprayed out through the second water collection pipe, spray pipe, and sprinkler head in turn for irrigation. The second water collection pipe is used for spraying at this time , improve the utilization rate of the device pipeline and save resources;

(3) The height of the funnel-shaped rainwater collector is the same as that of the filter layer, ensuring that the rainwater in the funnel-shaped rainwater collector can automatically flow into the storage tower without external force, simplifying equipment and saving resources. The number of spray pipes is 4 , to expand the spraying area, the spraying surface of the spraying head is a convex curved surface, so that the spraying surface reaches 180 degrees, and the spraying effect is enhanced.
