Description

Technical Field

[0001] The utility model relates to the field of ecological environmental protection, and in particular to a rainwater recycling device for a sponge city. Background Art

[0002] At present, many cities adopt the fast-discharge mode. When rainwater falls on the hardened ground, it can only be quickly discharged from the pipes. This mode causes 70% of the rainwater in the city to be lost in vain. If most of the rainwater is left instead of being discharged, the accumulation, infiltration and purification of rainwater in urban areas can be maximized, promoting the utilization of rainwater resources and the protection of the ecological environment. In order to solve the above problems, the concept of sponge city is proposed. The international common term for sponge city is "low-impact development rainwater system construction", which means building the city into a sponge body that can absorb, store, infiltrate and purify water when it rains, and release and utilize the stored water when needed.

[0003] The sponge city rainwater collection and recycling system with the publication number CN215105673U is retrieved, and includes: a road water collection module, a filter well, a filter module and a water storage tank. The above-mentioned sponge city rainwater collection and recycling system is set up on the road surface of the road, and the rainwater is discharged into the drainage channel through the permeable bricks and the water collection device. The rainwater is discharged into the filter well through the drainage channel and filtered by the filter module in the filter well. The filtered rainwater is finally collected in the underground water storage tank for storage. The water storage tank is equipped with a pump and corresponding pumping pipes, which can pump out the water in the water storage tank when needed, realizing the collection, filtration and storage of surface rainwater, making full use of natural resources and being green and environmentally friendly.

[0004] However, the above technical solution has the following problems: 1. Rainwater collection depends entirely on the road water collection modules, and the rainwater collection method is single and the collection amount is small; 2. Rainwater is filtered by setting filtration gravel in the filter well, but since the drainage channel is set at an angle and the filtration gravel is at the bottom of the drainage channel, when setting up large-scale road water collection modules, it is necessary to dig too deep a filter well to fill the gravel, which makes the construction difficult.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-9The utility model provides a rainwater recycling device for a sponge city, wherein an ordinary floor tile 1 is arranged on the ground of the sponge city, and a plurality of ordinary floor tiles 1 are laid on the ground, and an installation groove 10 is left between the ordinary floor tiles 1, and a collecting bucket 3 is arranged in the installation groove 10, and an infiltration pipe 4 is installed at the inner bottom of the collecting bucket 3, and an infiltration collection pipe 8 is connected to the bottom of the infiltration pipe 4 through a connecting pipe 7, and the infiltration collection pipe 8 is connected to a municipal water pool or a storage pool, and gravel loaded with a grid frame 6 is arranged inside the collecting bucket 3. As a preferred embodiment, the gravel in the grid frame 6 is divided into large-grain gravel, medium-grain gravel and small-grain gravel from top to bottom according to the particle diameter size, and rainwater is filtered by gravel of different particles to remove large-volume garbage mixed in the rainwater. A support frame 5 is provided on the upper surface of the grid frame 6, and a permeable floor tile 2 flush with the top of the mounting groove 10 is provided on the top of the support frame 5. The permeable floor tile 2 mentioned in this specification is a common technology in the existing sponge city technology. Rainwater can quickly penetrate from the surface of the permeable floor tile 2 to the ground. Its specific structure and working principle will not be explained in detail here.

[0031] In this embodiment, a positioning edge is provided on the inner wall of the opening of the installation groove 10, and the top of the collecting bucket 3 extends outward to form a limiting edge 303, and the limiting edge 303 corresponds to the positioning edge. In this way, the collecting bucket 3 can be fixed in the installation groove 10 through the cooperation of the limiting edge 303 and the positioning edge, and the collecting bucket 3 is prevented from sinking into the soil inside the installation groove 10.

[0032] In this embodiment, a water-permeable hole 302 is provided on the upper part of the collecting bucket 3, a circular water-permeable groove 301 is provided at the bottom center of the collecting bucket 3, a clamp ring 401 is provided on the outer side of the infiltration tube 4, and the infiltration tube 4 is installed in the water-permeable groove 301 through the clamp ring 401. The infiltration tube 4 can be fixed in the water-permeable groove 301 through the clamp ring 401. When there is too much rainwater in the collecting bucket 3 to be filtered in time, the excess rainwater penetrates into the surrounding soil through the water-permeable hole 302, so that the rainwater in the collecting bucket 3 is quickly discharged, so that more rainwater can be collected to prevent rainwater from accumulating on the ground.

[0033] In this embodiment, a first infiltration hole 402 is provided on the infiltration tube 4. By providing the first infiltration hole 402 on the infiltration tube 4, rainwater is filtered by gravel and then enters the infiltration collection tube 8 through the first infiltration hole 402. At the same time, the first infiltration hole 402 is provided to prevent gravel from entering the infiltration collection tube 8 and clogging the pipe.

[0034] In this embodiment, the support frame 5 includes a first porous plate 501 at the top and a second porous plate 502 at the bottom, the first porous plate 501 and the second porous plate 502 are fixedly connected by a support column 503, and a through slot 504 is provided on the second porous plate 502. In this way, the permeable floor tile 2 is supported by the support frame 5 to prevent the permeable floor from being stepped on and broken due to lack of bottom support, and the first porous plate 501 and the second porous plate 502 are provided to facilitate rainwater penetration and facilitate rainwater to flow into the collection bucket 3.

[0035] In this embodiment, a handle 601 passing through the through slot 504 is provided at the top of the grid frame 6, and a limiting slot 602 corresponding to the infiltration tube 4 is provided at the bottom of the grid frame 6. This arrangement facilitates the lifting of the grid frame 6 by the handle 601, facilitates the placement and removal of the grid frame 6 together with the gravel, and facilitates the positioning and fixing of the grid frame 6 by providing the limiting slot 602.

[0036] In this embodiment, the upper part of the infiltration collection tube 8 is provided with a second infiltration hole 801, and the two ends of the infiltration collection tube 8 are provided with corresponding matching plug-in ports 803 and plug-in rings 802. By providing the second infiltration hole 801 on the surface of the upper part of the infiltration collection tube 8 and using the filter cotton cloth 9, rainwater in the soil can pass through the filter cotton cloth 9 and the filtration of the second infiltration tube 4 to enter the infiltration collection tube 8, so that rainwater in the soil can be collected, the collection range can be improved, and the amount of rainwater collected can be increased. When in use, the plug-in ring 802 can be inserted into the plug-in port 803, and the plug-in ring 802 can be fixed with waterproof tape and screws to quickly complete the connection and fixation of the infiltration collection tube 8.

[0037] In this embodiment, the outer side of the infiltration collection tube 8 is wrapped with a filter cotton cloth 9. As a preferred embodiment, the filter cotton cloth 9 is divided into an outer permeable cloth structure and an inner sponge layer structure. By wrapping the filter cotton cloth 9 on the surface of the infiltration collection tube 8, rainwater in the soil can be filtered, and the filtered rainwater enters the infiltration collection tube 8 through the second infiltration hole 801.

[0038] When the amount of rainwater in the city is too much and needs to be discharged, the rainwater quickly penetrates into the collection bucket 3 through the first filtration of the permeable floor tiles 2. The rainwater flowing into the collection bucket 3 is filtered for the second time by gravel with particles of different diameters. The filtered rainwater enters the infiltration pipe 4 from the first infiltration hole 402, and flows to the municipal water pool or storage pool through the infiltration collection pipe 8 for storage. When needed, the rainwater is pumped out for use by a water pump.

[0039] When there is too much rainwater in the collecting bucket 3, the rainwater that cannot be filtered in time penetrates into the soil around the collecting bucket 3 through the water-permeable holes 302, so that the rainwater in the collecting bucket 3 is quickly discharged, which makes it convenient for the collecting bucket 3 to continue to collect rainwater, avoids rainwater accumulation on the ground, and facilitates the rapid penetration of rainwater.

[0040] At the same time, the filter cotton cloth 9 is used to allow rainwater in the soil to pass through the filter cotton cloth 9 and the filtration of the second infiltration tube 4 and enter the infiltration collection tube 8, thereby collecting the rainwater in the soil, improving the collection range, and increasing the amount of rainwater collected.
