Technical Field

[0001] The utility model relates to the technical field of rainwater utilization in sponge cities, in particular to a municipal rainwater utilization device in sponge cities. Background Art

[0002] Sponge city municipal rainwater utilization refers to the collection, storage, purification and rational use of urban rainwater resources through a series of natural and artificial measures under the guidance of the sponge city construction concept, so as to reduce urban flood disasters, alleviate the urban heat island effect, replenish groundwater, improve the urban ecological environment, and effectively improve the recycling rate of water resources. Specific implementation strategies and facilities include: 1. Rainwater collection system: Use roof green space, permeable pavement, rain garden, biological retention pond, infiltration well, infiltration channel and other facilities to collect urban surface runoff, reduce rainwater directly discharged into the sewer system, and reduce drainage pressure. 2. Rainwater purification and storage: The collected rainwater is initially purified through natural or artificial wetlands, vegetation filtration, sand and gravel infiltration and other ecological technologies, and then stored in underground reservoirs, rainwater barrels or large underground reservoirs for subsequent reuse. 3. Rainwater reuse: The purified rainwater can be used for various non-drinking purposes such as urban greening irrigation, road washing, toilet flushing, fire water, landscape water replenishment, etc., saving urban tap water consumption. 4. Intelligent management: Through intelligent monitoring and control systems, real-time monitoring of rainwater collection, purification and use can be carried out to optimize the allocation and utilization efficiency of rainwater resources and achieve refined and automated rainwater management. 5. Policy and planning guidance: Formulate corresponding policies and regulations to encourage and regulate the construction of rainwater collection and utilization systems, incorporate rainwater utilization into urban planning and construction project approval, and ensure the implementation of the sponge city concept in urban development. The core of municipal rainwater utilization in sponge cities lies in building a rainwater management system of "natural accumulation, natural infiltration, natural purification, and natural utilization", which not only solves the problem of urban rainwater management, but also promotes the sustainable use of water resources, which is of great significance to enhancing urban resilience and improving the urban ecological environment.

The sponge city rainwater utilization device includes a water collection tank, a water storage tank, a collection box and a filter box arranged in the water collection tank. The top of the filter box is provided with a filter port, the top outer wall of the water collection tank is provided with at least one water inlet, the inner wall of the water collection tank is provided with at least one inclined water guide plate, the water guide plate is used to guide the rainwater flowing into the water inlet to flow into the filter box through the filter port, a liftable filter pressing plate is provided in the filter box, the water collection tank is connected to a driving mechanism for driving the filter pressing plate to lift and lower, the filter pressing plate is provided with a first filter screen penetrating its upper and lower surfaces, the side wall of the filter box is provided with at least one through hole, and the bottom of the water collection tank and the bottom of the filter box are connected to the water storage tank and the collection box through the first pipe and the second pipe respectively. The sponge city rainwater utilization device can collect rainwater and filter impurities in the collected water flow, which is convenient for the staff to clean up the impurities in the collection box and use the clean rainwater in the water storage tank.

[0004] In terms of the utilization of rainwater from surface runoff, the existing sponge city mainly uses rainwater floor drains to drain rainwater into the interior of the sewer pipe, and then flows back into the sewage treatment plant through the pipe for treatment. However, there are the following problems with directly flowing rainwater into the municipal sewer pipe: First, during the flood season, a large amount of rainwater flowing into the pipe may increase the burden on the pipe and may even cause urban waterlogging, which will violate the original design intention of the sponge city.

In the long run, the groundwater level will not be replenished and the water level will drop. Directly introducing the moisture of surface runoff into the sewer pipe is not conducive to the replenishment of groundwater and the scientific construction of sponge cities. Utility Model Content

[0029] Working principle:

[0030] In the actual design process of the utility model, in order to solve the following defects existing in the prior art: "In terms of the utilization of rainwater from surface runoff in sponge cities in the prior art, rainwater floor drains are mainly used to drain rainwater into the interior of the sewer pipe, and then the rainwater flows back into the sewage treatment plant through the pipe for treatment. However, there are the following problems with directly flowing rainwater into the municipal sewer pipe: First, during the flood season, a large amount of rainwater flowing into the pipe may increase the burden on the pipe and may even cause urban waterlogging, which will violate the original design intention of the sponge city. Second, the existing urban road construction mainly uses cement roads to separate the surface and the underground. If the groundwater level cannot be replenished in the long run, the water level will drop. Directly introducing the moisture of surface runoff into the interior of the sewer pipe is not conducive to the replenishment of groundwater and the scientific construction of the sponge city." A groundwater repair stamping component 2 is proposed in a targeted manner;

[0031] When in use, the device is embedded and installed in a specific part of the municipal road, and the water collection tank 1 can collect the surface runoff generated on the road in real time; the water flowing into the pipe 12 squeezes the pad 10, so that the pad 10 pulls the spring 9, and then the pad 10 moves downward, and the water enters the inside of the infiltration pipe 11 through the chute 14, and the infiltration pipe 11 is inserted into the underground soil to achieve the effect of groundwater replenishment. In order to increase the flow rate, we installed a cylinder 5 on the slide 7, and realized a stamping structure through the cylinder 5, the slide 7 and the slide box 3, which is used to pressurize the infiltrating water, thereby accelerating the infiltration effect. In order to avoid the backflow of water, we installed a hook plate 8 on the top inner side of the pipe 12, and the hook plate 8 is connected to the pad 10 through the spring 9. When the water backflows, it can squeeze the pad 10, and the pad 10 can be filled on the surface of the pipe 12, thereby avoiding the occurrence of backflow.
