Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, specifically a sponge city infiltration and drainage device. Background Technology

[0002] Sponge city infiltration and drainage devices are technical systems designed to meet the needs of urban stormwater management. Their core functions include rainwater infiltration, retention, purification, and discharge. They aim to alleviate urban flooding, replenish groundwater, and improve water resource utilization efficiency. These devices typically combine permeable paving, sunken green spaces, bioretention facilities, infiltration wells, and rain gardens with low-impact development (LID) technologies to control rainwater runoff by simulating the natural hydrological cycle.

[0003] When traditional infiltration and drainage devices are in operation, pollutants such as mud, leaves, and garbage carried by rainwater will accumulate inside the drainage pipe network, forming a silt layer. This will reduce the cross-sectional area of ​​the pipe network and decrease the drainage capacity. Cleaning the device requires disassembling it, which is not only cumbersome but also increases operation and maintenance costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown in the embodiment of this utility model, a sponge city infiltration and drainage device includes an underground layer 1; a load-bearing frame 19 is detachably connected to the top of the underground layer 1; multiple permeable concrete bodies 111 distributed at equal intervals are detachably connected to the top of the load-bearing frame 19; a filter assembly is slidably connected to the middle of the underground layer 1 near the load-bearing frame 19; an infiltration pipe 11 is detachably connected to the middle of the filter assembly; a drainage network pipe 13 is fixedly connected to the middle of the infiltration pipe 11; a water storage tank 110 is fixedly connected to the end of the drainage network pipe 13; a fixing frame 14 is fixedly connected to the end of the drainage network pipe 13 near the water storage tank 110; an elastic rope 15 is fixedly connected to the middle of the fixing frame 14; a fixing buckle 18 is fixedly connected to the middle of the drainage network pipe 13 away from the fixing frame 14; two symmetrically arranged elastic balls 17 are slidably connected to the middle of the elastic rope 15; the elastic rope 15 A cleaning brush 16 is slidably connected to the middle of the elastic ball 17; a recovery pipe 12 is fixed to the side wall of the water storage tank 110 away from the drainage network pipe 13; during operation, as the drainage network pipe 13 transports rainwater to the middle of the water storage tank 110, the impact force of the water flow will cause the cleaning brush 16 to come into contact with the elastic ball 17. The elasticity of the elastic ball 17 allows the cleaning brush 16 to slide back and forth in the middle. While sliding, the brush in the middle of the cleaning brush 16 can be used to clean the inner wall of the drainage network pipe 13, preventing the drainage network pipe 13 from being blocked and affecting work efficiency. Through the above structure, the sediment such as mud, leaves and other deposits attached to the inner wall of the drainage network pipe 13 can be effectively removed, avoiding the reduction of the diameter of the drainage network pipe 13, which would lead to problems such as reduced drainage capacity and local water accumulation due to blockage, thus reducing the risk of urban flooding.

[0025] like Figures 2 to 3 As shown, two sets of buckles 22 are detachably connected to the side wall of the underground layer 1 near the load-bearing frame 19; a placement rack 2 is fixed to the side wall of the buckles 22; a protective net 21 is fixed to the side wall of the placement rack 2 near the underground layer 1; a first filter plate 23 is fixed to the middle of the placement rack 2 near the protective net 21; when in operation, water-tolerant plants can be planted in the middle of the placement rack 2, and pollutants in rainwater can be removed by the physical adsorption and biodegradation of the plants, reducing the burden on the filter components when filtering them. The detachable design makes it easier to clean. Through the above structure, not only can the corrosion of the filter components by pollutants in rainwater be reduced, but also the problems of surface pollution and soil erosion can be effectively avoided, which can beautify the urban environment and enhance the ecological value of the city.

[0026] like Figure 2As shown, the filter assembly includes sliders 3; two sets of symmetrically arranged sliders 3 are slidably connected to the middle of the basement 1 near the support frame 19; a trapezoidal plate 31 is fixed to the middle of the placement frame 2; a second filter plate 32 is fixed to the middle of the trapezoidal plate 31; during operation, when the filter element is placed in the middle of the second filter plate 32, rainwater can flow from top to bottom. At this time, the particulate matter in the rainwater will be gradually intercepted by gravity, forming a graded filtration. The detachable design makes it easier to clean. Through the above structure, the filtration effect can be achieved by physical interception and gravity sedimentation. Moreover, the graded filtration can reduce the frequency of clogging of the second filter plate 32, prevent impurities from depositing on the surface of the second filter plate 32, extend the cleaning cycle, and reduce the maintenance frequency of the device.

[0027] like Figure 4 As shown, a fixing ring 4 is detachably connected to the end of the recycling pipe 12 near the fixing frame 14; a purifier 41 is fixedly connected to the middle of the fixing ring 4; during operation, the fixing ring 4 and the purifier 41 can reduce the impact of pipe vibration on the purification effect, and the purifier 41 can physically filter the rainwater to remove heavy metals, organic matter and other substances from the rainwater, thereby improving water quality. Through the above structure, pollutants can be effectively and deeply removed, and the purified rainwater can be directly used for greening irrigation or to replenish groundwater, avoiding problems such as substandard purity of recycled water causing harm to plant growth or soil pollution.

[0028] like Figure 4 As shown, two grid plates 5 are fixedly connected to the middle of the water storage tank 110 near the purifier 41; the two grid plates 5 are symmetrically arranged; when working, the grid plates 5 can not only intercept larger solid particles carried by rainwater, but also place adsorption plates in the middle to remove suspended solids and other organic pollutants in the rainwater, thereby improving the water purification effect. Through the above structure, the combination of the two can effectively achieve interception and adsorption, significantly improve the rainwater purification capacity, reduce the risk of equipment damage, avoid secondary pollution, and ensure the safety of reclaimed water quality.

[0029] like Figure 2 As shown, an anti-slip mat 6 is fixed to the top of the permeable concrete body 111; the anti-slip mat 6 is made of rubber; during operation, the permeable concrete body 111 allows rainwater to quickly and vertically penetrate downwards, while the anti-slip mat 6 increases the friction between the road surface and the tires, providing better anti-slip performance for pedestrians and vehicles. Through the above structure, not only can drainage be effectively carried out to avoid road water accumulation, but also the problem of slipping and falling and traffic accidents caused by wet road surfaces can be effectively avoided, thus improving safety.

[0030] like Figure 1As shown, the middle part of the trapezoidal plate 31 and the second filter plate 32 are coated with polytetrafluoroethylene. During operation, this coating has a low surface layer, making it difficult for pollutants in rainwater to adhere to the filter material surface in the middle of the second filter plate 32. Through the above structure, it can effectively resist the corrosion of strong acids, strong alkalis and other chemicals, and always maintain the integrity of the filter layer structure and good filtration effect.

[0031] During operation, as rainwater is transported from the drainage network 13 to the middle of the storage tank 110, the impact of the water flow causes the cleaning brush 16 to come into contact with the elastic ball 17. The elasticity of the elastic ball 17 allows the cleaning brush 16 to slide back and forth in the middle. While sliding, the brush in the middle of the cleaning brush 16 can clean the inner wall of the drainage network 13, preventing the drainage network 13 from being blocked and affecting work efficiency. Water-tolerant plants can be planted in the middle of the shelf 2. The plants remove pollutants from the rainwater through physical adsorption and biodegradation, reducing the burden on the filter components. The detachable design makes cleaning easier. When the filter element is placed in the middle of the second filter plate 32, the rainwater can flow from top to bottom. At this time, the particulate matter in the rainwater will be gradually removed by gravity. The system intercepts and forms a tiered filtration system. Its detachable design makes it easier to clean. The fixing ring 4 and purifier 41 reduce the impact of pipe vibration on the purification effect. The purifier 41 can physically filter rainwater, removing heavy metals, organic matter, etc., and improving water quality. The grating plate 5 can not only intercept larger solid particles carried in rainwater, but also has an adsorption sheet in its middle to remove suspended solids and other organic pollutants from rainwater, improving the water purification effect. The permeable concrete body 111 allows rainwater to quickly and vertically infiltrate downwards, while the anti-slip mat 6 increases the friction between the road surface and tires, providing better anti-slip performance for pedestrians and vehicles. This coating has a low surface layer, making it difficult for pollutants in rainwater to adhere to the filter material surface in the middle of the second filter plate 32.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
