Description

An intelligent three-dimensional rainwater reuse ecological landscape corridor and its work flow

Technical field

The invention relates to landscape corridors, and in particular to an ecological landscape corridor for intelligent three-dimensional rainwater reuse and its work flow.

Background technique

Corridors are set up in many residential areas, squares, parks and other public areas. Various flowers and plants are planted around and on top of the corridors to green the surrounding environment. Corridors are generally composed of two rows of side wall bases and beams located on top of the bases. The frame structure materials of the corridor include reinforced concrete, wood, steel structure, etc. Plants around the corridor require regular maintenance. Only a small amount of plant maintenance relies on natural rainwater irrigation, and most of the rest rely on artificial watering.

At present, most corridors have a single landscape effect and lack a sense of three-dimensional space. If prefabricated plant boxes are arranged on both sides and top of the corridor, and various flowers and plants are planted in the plant boxes, this will greatly improve the landscape effect of the corridor. In recent years, the concept of "sponge city" has become more and more popular, and people have paid more and more attention to the collection and reuse of rainwater. Landscape maintenance after the corridor is built requires a lot of manpower and water resources. If the rainwater in the corridor landscape coverage and surrounding areas can be captured and stored, and with the help of the PLC control system, when the corridor landscape needs irrigation, the stored rainwater can be used to achieve intelligent irrigation. This will greatly reduce the subsequent maintenance work and have good economic benefits.

The rainwater from the surface around the corridor flows into the water collection ditch after being filtered by the filter box and then flows into the reservoir; when there is too much rainwater in the reservoir, it is discharged into the urban rainwater pipe network through the overflow ditch;

4) When the humidity sensor in any prefabricated plant box detects that the water content of the soil layer in the prefabricated plant box is low, the PLC controller issues an instruction to start the water pump, close the first control valve, and open the second control valve. At this time, the water pump extracts rainwater from the reservoir through the irrigation water pipes and irrigation branch pipes to the sprinklers on both sides of the corridor, or extracts rainwater and transports it through multi-functional water pipes to the sprinklers of the irrigation branch pipes at the top of the corridor to achieve irrigation;

While irrigating, a beautiful fountain dynamic waterscape is formed above the cover. The fountain water falling on the cover is filtered by the filter filler in the round hole and then falls back into the reservoir;

When the humidity sensor in the prefabricated plant box detects that the moisture content of the soil layer in the prefabricated plant box reaches a reasonable value, the PLC controller issues an instruction to turn off the water pump to stop irrigation, open the first control valve, and close the second control valve; In this way, rainwater is used to realize intelligent irrigation of corridor landscape;

5) When the water pump is working, the water level sensor detects that the amount of rainwater in the reservoir is low, and the PLC controller issues an instruction to shut down the water pump. (The water level sensor detects that the amount of rainwater in the reservoir is low. At the same time, the humidity sensor detects that the water content of the soil layer in the prefabricated plant box is low.
