Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage engineering technology, and in particular to a rainwater runoff collection and regulation system for urban ecological green spaces. Background Technology
[0002] After rainwater falls to the ground, it infiltrates into the soil, replenishing groundwater, and also forms water flows on the surface, which are called rainwater runoff. The formation of rainwater runoff is affected by rainfall intensity, rainfall duration, and the material and slope of the ground. During its flow, it carries various pollutants and becomes sewage, which flows along the terrain into the city's drainage network and into surrounding natural water bodies, thereby increasing the burden on urban sewage treatment plants and polluting the aquatic environment, affecting the health of aquatic ecosystems. Therefore, a runoff collection and regulation system is needed to achieve the initial storage and natural purification of rainwater runoff, improve the efficiency of rainwater resource utilization, alleviate the risk of urban flooding, reduce the pollution of the urban water environment caused by rainwater runoff, and promote the sustainable development of the urban ecological environment.
[0003] A search revealed Chinese Patent Publication No. CN219459884U, which discloses a rainwater collection and storage system for terraced greenhouses. Rainwater intercepted by the greenhouse flows entirely into a collection ditch built at the base of the greenhouse. Rainwater runoff from the planting area outside the greenhouse is diverted into a micro-sedimentation tank through segmented interception methods such as ridge planting or straw mulching. The runoff carrying sediment is filtered and settled here. Submersible pumps are installed in the collection ditch and the micro-sedimentation tank, allowing the purified rainwater to be pumped to a storage tank via water pipes for irrigation of crops in the greenhouse. This utility model achieves efficient regulation and utilization of rainwater runoff through collection. The greenhouse intercepts rainfall, blocking erosion runoff flowing into the outside of the greenhouse and also intercepting rainwater runoff in the planting area outside the greenhouse, thus reducing the erosion of the terraced soil. Irrigation is carried out using rainwater stored in the reservoir, maximizing the use of rainwater resources. This effectively improves the ecological environment of the terraced ecosystem and promotes the sustainable development of high-efficiency agriculture. However, the above structure does not take into account stratified filtration. When the rainfall is heavy, the purification effect will decrease significantly, making it difficult to meet high water quality standards. It is also prone to problems such as pipeline pressure and waterlogging. The lack of automatic irrigation results in low resource utilization, increases labor and material costs, and makes it difficult to meet the usage needs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an urban ecological green space rainwater runoff collection and regulation system, which aims to improve the problems of poor water filtration, high pipeline pressure, easy flooding, and high cost due to lack of automation in the existing technology.

[0040] Specifically, the water collection tank 1 is an important device for temporarily storing water.

At the end of the water channel 12, the rotating nozzles 11 are evenly arranged, so as to ensure that the water can be sprayed evenly on the trees and improve the irrigation effect.
[0045] Please see the appendix Figure 1 and attached Figure 5The protective shell 202 has a plate slot 16 on the front side, and a nameplate 17 is fixedly connected to the inner wall of the plate slot 16.

The solar panel 207 is designed to be at the same horizontal height to ensure that it can receive solar energy evenly under sunlight, thereby improving energy conversion efficiency. A controller 18 is fixedly connected to the right side of the protective shell 202. The controller 18 is an important component for controlling the entire structure.

[0047] Working principle: Rainwater is introduced into the filtration area through the water pipe 6 beside the road. The rainwater is first initially filtered by the coarse filter 5 to remove large particles of impurities. Then it enters the sand and gravel layer 4 for a second filtration to settle the impurities. Finally, it enters the activated carbon layer 3 for filtration to adsorb organic matter and odors. Then it is collected in the water collection tank 1. The rainwater filtered in the water collection tank 1 is transported to the water storage tank 8 by the submersible pump 7. When the rainwater accumulates to the designated water level, the liquid level sensor 15 is triggered, which controls the submersible pump 9 to transport the rainwater in the water storage tank 8 to the water supply pipe 10. Since multiple rotating nozzles 11 are installed on the water supply pipe 10, the purified and usable rainwater inside is sprayed out from the rotating nozzles 11. Through reasonable layout and water pump control, spraying is carried out at specific times and frequencies to supply water to the trees in the square. This multi-stage filtration improves the quality of rainwater, ensures the healthy growth of the trees in the square, alleviates the pressure on the urban drainage network and the problem of waterlogging. Automatic irrigation improves the utilization rate of resources, reduces the cost of manpower and materials, and meets the needs of use.
[0048] By setting a support frame 201 above the water storage area, the rotating column 206 is rotatably connected between two support frames 201. A protective shell 202 is installed on the support frame 201 to prevent the external spraying environment from affecting the servo motor 203 fixedly connected inside. When the servo motor 203 rotates slowly in both directions, it drives the gear 204 at its output end to rotate synchronously. The gear 204 meshes with the transmission gear 205 to form a reduction mechanism, thereby controlling the rotation of the rotating column 206. Since multiple solar panels 207 are installed on the rotating column 206, the solar panels 207 can rotate slowly over time, so that the side receiving solar energy receives the maximum amount of solar energy. This structure improves the utilization rate of solar energy, increases the energy self-sufficiency rate of the structure, reduces dependence on the external power grid, and has high economic and environmental benefits, meeting the electricity demand.
