Technical Field
[0001] This utility model relates to the field of rainwater purification technology for sponge cities, specifically a rainwater purification and recycling device for sponge cities. Background Technology
[0002] A sponge city refers to a city that, like a sponge, possesses excellent resilience in adapting to environmental changes and responding to natural disasters. It absorbs, stores, infiltrates, and purifies rainwater during rainfall, and releases and utilizes the stored water when needed. The construction of sponge cities should adhere to principles such as ecological priority, combining natural methods with artificial measures. While ensuring urban drainage and flood control safety, it should maximize the accumulation, infiltration, and purification of rainwater in urban areas, promoting the utilization of rainwater resources and ecological environmental protection. Rainwater is an important source of urban water resources. Collecting, purifying, and reusing rainwater can alleviate urban flood control and drainage pressures, reduce pipeline construction costs, and regulate and replenish regional water resources. As a pathway to restore urban aquatic ecosystems, sponge cities can achieve water recycling and reuse, conserve water, and address the increasingly severe ecological crisis facing many cities, minimizing damage to the original urban aquatic ecosystem. Therefore, a rainwater purification and recycling device for sponge cities is urgently needed.
[0003] Currently, when rainwater is purified and utilized in sponge cities, it is inconvenient to use the rainwater for irrigating urban green vegetation, which makes it difficult to save irrigation water. Utility Model Content

[0010] Preferably, the connecting support shell is provided with water guiding holes evenly distributed.
[0011] Preferably, the top of the rainwater pipe is provided with linearly distributed fixing bolts.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This sponge city rainwater purification and recycling device involves laying rainwater pipes along city streets, placing flower planting boxes on both sides of the rainwater pipes, and supporting filter panels on the top of the rainwater pipes via connecting brackets. The filter panels facilitate the filtration of branches and leaves in the rainwater. Rainwater flows through the rainwater pipes, and drainage holes allow the rainwater to be sequentially directed into pebble troughs, gravel troughs, and expanded clay troughs. By placing corresponding filter stones inside the pebble troughs, gravel troughs, and expanded clay troughs, the rainwater is easily filtered. The pebbles, gravel, and expanded clay granules are larger than the drainage holes, facilitating layer-by-layer filtration of the collected rainwater. The filtered rainwater is then easily directed through the drainage holes into the connecting bracket, which is also filled with pebbles, enhancing both aesthetics and further filtration of the rainwater. 2. This sponge city rainwater purification and recycling device connects the flower planting box to the rainwater pipe via a connecting bracket and a connecting frame. The flower planting box uses the connecting bracket and water guide holes to guide filtered rainwater to the bottom of the flower planting box for storage. The cross bracket in the middle of the flower planting box facilitates the fixing of the connecting plate. The connecting plate can easily seal the middle of the flower planting box, making it convenient to place planting soil inside for planting urban greening flowers and plants. The water inlet holes on the connecting plate allow rainwater at the bottom of the flower planting box to enter the soil through the plant roots, providing supplementary water supply.

The cross bracket 21 in the middle part of the flower planting box 2 facilitates the fixing of the connecting plate 12. The connecting plate 12 facilitates the sealing of the middle of the flower planting box 2, making it convenient to place planting soil inside for planting urban greening flowers and plants. The water inlet hole 23 on the connecting plate 12 facilitates the rainwater at the bottom of the flower planting box 2 to enter the soil through the plant roots, which helps to provide water.
[0018] Working principle: Rainwater pipes 1 are laid on city streets, and flower planting boxes 2 are placed on both sides of the rainwater pipes 1. The top of the rainwater pipes 1 is supported by a filter plate 13 via a connecting bracket 12. The filter plate 13 facilitates the filtration of branches and leaves in the rainwater. Rainwater flows through the rainwater pipes 1, and the drainage holes 14 facilitate the sequential introduction of rainwater into the pebble trough 15, the gravel trough 16, and the expanded clay trough 17. By placing corresponding filter stones inside the pebble trough 15, the gravel trough 16, and the expanded clay trough 17, the rainwater is easily filtered. The pebbles, gravel, and expanded clay granules are larger than the drainage holes 14, facilitating the layered filtration of the collected rainwater.
