[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and cope with natural disasters caused by rain like a sponge, with good elasticity. It can also be called a "water-elastic city". The city can adapt to environmental changes and cope with natural disasters like a sponge. The internationally common term is "low-impact development rainwater system construction". It absorbs, stores, infiltrates and purifies water when it rains. When needed, the stored water will be released and utilized to achieve the free migration of rainwater in the city.

[0003] In this regard, China's patent application number: CN 213268245 U discloses a self-circulating infiltration and storage structure of a sponge city rain garden, which includes: a water collection well and a water storage well, a filtering component and an irrigation component. The water storage well is connected to the water collection well through a connecting pipe, the filtering component is installed in the water storage well to filter the water in the water storage well, and the irrigation component is arranged in the water storage well to pump water to irrigate the plants. This application has the effect of improving the difficulty of collecting and utilizing rainwater.

[0004] However, in actual use, this structure can only use simple seepage water storage. When pumping water for irrigation, it is impossible to complete the comprehensive and uniform circulation of the stored water, which affects the planting effect of sponge city greening plants. At the same time, the equipment cannot perform efficient drainage during the rainy season and efficient cleaning and maintenance operations at the water storage area, and cannot meet daily use needs. Therefore, it is urgent to design a sponge city rainwater self-circulating seepage storage structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a self-circulating rainwater infiltration and storage structure for a sponge city, so as to solve the problem that the existing structure proposed in the above background technology can only adopt simple infiltration and water storage in actual use, and cannot complete the comprehensive and uniform circulation of the stored water during pumping and irrigation, which affects the planting effect of green plants in the sponge city. At the same time, the equipment cannot perform efficient drainage during the rainy season and efficient cleaning and maintenance operations at the water storage area, and cannot meet the daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a sponge city rainwater self-circulation infiltration and storage structure, comprising a flow frame, the top of which is fixedly connected to an embedded frame, the top of which is fixedly connected to a planting frame, and a guide cone frame is arranged inside the planting frame;

[0007] A water storage tank, wherein the bottom end of the flow rack is fixedly connected to the water storage tank, the bottom end of the water storage tank is fixedly connected to a supporting bottom plate, a pumping unit is arranged on one side of the top end of the water storage tank, and a water level measuring device is arranged on one side of the inner wall of the water storage tank.

[0008] Preferably, the front of the water storage tank is movably connected to a side panel, and mounting bolts are provided at the four corners of the side panels.

[0009] Preferably, a liquid control valve is fixedly connected to the side of the water pumping unit, and a delivery pipe is fixedly connected to the top of the liquid control valve.

[0010] Preferably, a pouring ring seat is fixedly connected to the top of the planting rack, and a pouring grid is provided on the inner wall of the pouring ring seat.

[0011] Preferably, a seepage plate is provided on the inner bottom wall of the guide cone frame, and a seepage filter element is provided on the inner wall of the seepage plate.

[0012] Preferably, a first drain valve is provided at one end of the flow rack, and a second drain valve is provided at the other end of the flow rack.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The rainwater self-circulation infiltration and storage structure of the sponge city can make the equipment more efficient in the self-circulation infiltration and storage of rainwater in the sponge city through the flow rack, embedded rack, planting rack, guide cone rack, water storage tank, supporting bottom plate, pumping unit, liquid control valve, delivery pipe, pouring ring seat, pouring grid, seepage plate and seepage filter element. In the actual use process, the staff first planted the green plants in the sponge city in the guide cone rack of the planting rack through the soil. When it rains daily, the rainwater can penetrate into the soil and pass through the guide cone rack from the seepage filter element of the seepage plate. It infiltrates into the flow rack and falls into the water storage tank along the flow rack guide for water storage. Later, the pumping unit can be started to quickly pump the stored water to the pouring ring seat at the top of the planting rack through the liquid control valve and the delivery pipe, and then the pouring grid on the inner wall of the pouring ring seat can be used to evenly water the green plants as a whole, thereby improving the watering efficiency. The watering water can infiltrate into the guide cone frame of the planting rack and then infiltrate into the flow rack from the seepage filter element of the seepage plate again, so that rainwater can be quickly circulated and irrigated, thereby improving the watering effect and reflecting the practicality of the equipment design.

[0015] 2. The rainwater self-circulating infiltration and storage structure of the sponge city further improves the overall use effect of the equipment through the flow rack, embedded rack, planting rack, water tank, water level meter, side plate, mounting bolt, first drain valve and second drain valve. In daily use, the internal water storage volume of the water tank can be quickly measured by the water level meter, and the water tanks can also quickly flow with each other to realize the operation of artificial addition of water storage. The side of the water tank can be quickly disassembled and assembled through the side plate and mounting bolt to realize internal cleaning and maintenance operations. At the same time, when the rainwater is heavy and the water tank is full, the first drain valve and the second drain valve at both ends of the flow rack can be used to quickly divert the rainwater, thereby realizing protection during the flood season and reducing the problem of urban waterlogging that may occur in the sponge city due to rainwater, which reflects the comprehensiveness of the equipment design.
