Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection equipment, in particular to a rainwater collection and reuse system for landscapes. Background Technique

[0002] In current urban construction, the maintenance and management of landscape green spaces often rely on traditional irrigation systems, which usually directly use municipal water supply. This not only incurs high costs but also consumes a large amount of water resources. Especially in arid regions or cities with water shortages, this irrigation method that depends on municipal water supply is particularly unsustainable.

[0003] The patent with the publication number CN206486927U discloses a rainwater collection and reuse system based on the integration of community green landscapes, including a roof rainwater collection system, a ground rainwater collection system, and a rainwater storage and reuse system. The roof rainwater collection system includes a roof garden rainwater collection system, downspouts, and a high-position filtration and purification device. The roof garden rainwater collection system conveys excess rainwater through the downspouts to the high-position filtration and purification device for purification. The end of the high-position filtration and purification device and the end of the ground rainwater collection system are both connected to the water inlet pipe of the rainwater storage and reuse system. The utility model effectively combines landscape greening and rainwater collection and reuse, solves the need for greening water, and at the same time purifies and filters rainwater through vegetation, making full use of rainwater resources. It has good treatment effects, low treatment costs, is easy to use widely, and has the characteristics of beauty, practicality, and convenient management, facilitating the achievement of water volume balance.

[0004] The above-mentioned prior art uses a horizontal flow type transmission vegetation shallow trench to introduce rainwater into the ground rainwater delivery pipe, and a intercepting and filtering device is provided at the pipe orifice of the ground rainwater delivery pipe to prevent impurities from entering the rainwater storage and reuse system. However, the horizontal flow type transmission vegetation shallow trench is easily blocked by fallen leaves and dust after long-term use, resulting in the failure of the water guiding function of the horizontal flow type transmission vegetation shallow trench. Moreover, the shape and structure of the horizontal flow type transmission vegetation shallow trench make it difficult to clean, presenting difficulties in maintenance. In view of this, we propose a rainwater collection and reuse system for landscapes. Content of the Utility Model

The output end of the water injection pipe penetrates through the right side of the water storage tank to the inside of the water storage tank. When the electromagnetic valve is opened, the water injection pipe replenishes water into the water storage tank, avoiding damage to the pump body due to water shortage in the water storage tank and avoiding water shortage in the irrigation system at the same time.

When the second water level sensor 85 detects that the water level reaches the high water level, the controller 83 controls the solenoid valve 82 to close and stop replenishing water. If the rainwater in the water tank 6 exceeds a certain water level, the overflow pipe 60 discharges the excess rainwater into the municipal rainwater pipe to prevent the water tank 6 from overflowing. The first filter box 20 and the second filter box 51 are both detachable in design, which is convenient for the staff to regularly take out and clean the filtered objects to maintain the normal operation of the system. Through the above-mentioned usage, the system can efficiently collect and reuse rainwater, reduce dependence on municipal water supply, and reduce the cost of greening water use, especially in drought or water-scarce areas, with significant water-saving and economic benefits.
