The top of the water inlet trough 3 is tilted so that rainwater can flow into the water inlet trough 3 more smoothly, thereby improving the collection efficiency of rainwater. At the same time, the tilted setting is also conducive to the impurities and pollutants in the rainwater being washed away during the flow process, thereby further improving the quality of the rainwater.

[0027] As a preferred embodiment of the present invention, a partition plate 24 is fixedly connected to the inside of the water storage tank 2 near the bottom, and a connecting pipe 20 is arranged horizontally below the partition plate 24, both ends of the connecting pipe 20 extend to the outside of the water storage tank 2, and a water outlet pipe 21 connected to the connecting pipe 20 is installed in the middle of the partition plate 24, and a first manual valve 22 is installed on the water outlet pipe 21. The partition plate 24 can make the water storage tank 2 have the function of storing water, and the connecting pipe 20 and the water outlet pipe 21 are convenient for controlling the water outlet of the water storage tank 2. It should be added that flanges are installed at both ends of the connecting pipe 20, and when the two walls 1 are spliced, the two connecting pipes 20 in the two walls 1 can be connected by the flanges.

[0028] As a preferred embodiment of the present invention, a diverter plate 23 is fixedly connected to the inside of the water storage tank 2 near the top, and the two sides of the diverter plate 23 are inclined toward the middle, and the diverter plate 23 is provided with a plurality of evenly distributed diverter holes. The diverter plate 23 is provided to divert the rainwater inside the water storage tank 2, so that the rainwater can be more evenly distributed on the filter assembly, thereby improving the filtering effect and processing efficiency. The diverter holes on the diverter plate 23 further enhance the dispersion effect of the rainwater, so that each part of the rainwater can be fully processed.

[0029] As a preferred embodiment of the present invention, the filter assembly includes a primary filter 25, a secondary filter 26, filter cotton 27 and an adsorption layer 28 arranged in sequence from top to bottom, and the mesh diameter of the secondary filter 26 is smaller than that of the primary filter 25. The filter assembly includes a primary filter 25, a secondary filter 26, filter cotton 27 and an adsorption layer 28 arranged in sequence from top to bottom, thereby realizing multi-stage filtration and treatment of rainwater. The mesh diameters of the primary filter 25 and the secondary filter 26 gradually decrease, and impurities and pollutants of different sizes can be filtered out in turn. The filter cotton 27 further removes tiny particles and suspended matter in the rainwater, thereby improving the clarity of the rainwater. The adsorption layer 28 can absorb harmful substances and odors in the rainwater, thereby improving the quality of the rainwater. Overall, the filter assembly has an efficient and stable filtering effect, and can meet the requirements for rainwater treatment in the construction of sponge cities.

[0030] As a preferred embodiment of the present invention, the filter assembly is fixedly installed between the diverter plate 23 and the partition plate 24. A conical groove is provided on the top of the partition plate 24, and the bottom of the groove points to the top nozzle of the outlet pipe 21. The filter assembly is fixedly installed between the diverter plate 23 and the partition plate 24, so that the filter assembly can be stably supported and positioned, ensuring the filtering effect and processing efficiency. The conical groove design on the top of the partition plate 24 is conducive to guiding the treated rainwater to the outlet pipe 21, which is convenient for users to take.

[0031] As a preferred embodiment of the present invention, an external pipe 29 is installed on the front outer wall of the water storage tank 2, the external pipe 29 is connected to the connecting pipe 20, and a second manual valve 290 is installed on the external pipe 29. The setting of the external pipe 29 and the second manual valve 290 provides the user with an additional water intake and control means. The user can connect other equipment or pipelines through the external pipe 29 to guide the rainwater inside the water storage tank 2 to the required place for use. The second manual valve 290 can control the on-off and flow rate of the external pipe 29, which is convenient for the user to flexibly adjust and operate.

[0032] As a preferred embodiment of the present invention, a planting box 50 is fixedly mounted on each planting hole of the mounting plate 5, and a guide plate 6 is fixedly connected to the top of the water inlet trough 3 between the blocking net 30 and the planting box 50. The arrangement of the planting box 50 provides an independent growth space for the plants, so that each plant can obtain sufficient nutrients and growth conditions, and the guide plate 6 mainly plays a role of partition.

[0033] When the retaining wall device based on sponge city construction of the utility model is in use, when rainwater falls on the device, it will first fall on the top of the water inlet trough 3. Subsequently, the rainwater is guided to the inside of the water storage tank 2 through the downpipe 4, realizing the transfer and storage of rainwater.

[0034] Inside the water storage tank 2, rainwater first contacts the diverter plate 23. The diverter plate 23 is set to divert the rainwater so that it can be more evenly distributed on the filter assembly. The rainwater is then filtered and processed by multiple stages of the filter assembly, including the primary filter 25, the secondary filter 26, the filter cotton 27 and the adsorption layer 28. These filter levels filter out impurities and pollutants of different sizes in turn, improving the quality of the rainwater.

[0035] The filtered rainwater continues to flow downward and is finally stored at the bottom of the water storage tank 2. When the rainwater needs to be used, the first manual valve 22 can be opened to allow the rainwater to flow out of the outlet pipe 21. In addition, the user can also control the outflow amount and flow direction of the rainwater through the external pipe 29 and the second manual valve 290 to meet different water needs.
