[0002] With the continuous acceleration of urbanization, urban waterlogging is becoming increasingly serious. Traditional urban drainage systems rely primarily on pipelines and pumping stations. These facilities often struggle to quickly remove large amounts of rainwater during short, intense rainfall events, leading to frequent problems such as waterlogging on roads and traffic disruptions. To address this issue, the concept of sponge city development has emerged. Through a comprehensive approach of "infiltration, retention, storage, purification, utilization, and drainage," sponge cities aim to enhance a city's ability to absorb, infiltrate, and slowly release rainfall, effectively controlling stormwater runoff and achieving natural accumulation, infiltration, and purification.

[0003] However, in the process of sponge city construction, how to efficiently collect and utilize road rainwater has become a pressing issue. Therefore, a sponge city road rainwater collection and utilization device that can efficiently collect road rainwater, ensure water quality, and has stable installation and convenient water collection is urgently needed to solve the above problems.

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0032] See also Figure 1-8 As shown, the present invention is a rainwater collection and utilization device for sponge city roads. It includes a water collection device installed on the side of the road and a water storage device buried underground. The water storage device includes a water storage tank 1 and a water collection and storage upper tank 2. The water collection device and the water collection and storage upper tank 2 are connected by a water pipe 3. When it rains, water on the road flows to the water collection device on the side of the road, and then is directed to the water storage device through the water pipe 3 for use.

[0033] To ensure water quality within tank 1, ventilation is provided between the water inside and the ground. Several ventilation holes 11 are provided at the bottom of tank 1. A gauze layer 4 is laid on the bottom of tank 1. A breathable, anti-seepage sand layer 5 is placed above this layer. This layer effectively ensures ventilation within tank 1 while reducing water loss through the ground. A gravel layer 6 is placed above this layer to buffer any water entering tank 1 from above, preventing it from damaging the effectiveness of the layer.

[0034] Among them, the water collection device specifically includes a water collection tank body 7 and a cover plate 8. The water collection tank body 7 is a rectangular tank structure with an upper opening. A first joint 71 connected to the water pipe 3 is fixed through one side wall of the water collection tank body 7. The cover plate 8 is an inverted U-shaped folded plate. A plurality of water filter holes 81 are provided on the top surface of the cover plate 8. When the cover plate 8 is buckled inside the water collection tank body 7, the top surface of the cover plate 8 is flush with the open end surface of the water collection tank body 7. A diversion groove 82 that cooperates with the first joint 71 is provided on one side wall of the cover plate 8.

[0035] To ensure a stable connection between the water collection tank body 7 and the underlying paving layer during installation, a number of V-shaped plates 72 are symmetrically fixed to the bottom surface of the water collection tank body 7. In addition, to reduce the risk of rainwater flowing over the cover plate 8 without entering the water collection tank body 7 below, an upwardly extending water retaining plate 73 is provided on the upper end of one side wall of the water collection tank body 7 to block rainwater and increase the collection rate of road rainwater by the water collection device.

[0036] The water storage tank 1 specifically includes a cylindrical tank body. A first plug-in tube 12 is provided at the upper end of the water storage tank 1. The water collection and storage upper tank 2 specifically includes a cylinder 21. A first semicircular cover plate 22 is fixed to the upper end of the cylinder 21. The first semicircular cover plate 22 is rotatably connected to a second semicircular cover plate 23 via a hinge. A second plug-in tube 24 is fixed to the lower end of the inner wall of the cylinder 21, which plugs into and cooperates with the first plug-in tube 12. A rectangular trough body 25 with a side opening is fixed through the side wall of the cylinder 21. A row of second connectors 26 connected to the water pipe 3 are fixed through the trough wall opposite the open end of the rectangular trough body 25, and the inner end of the second connector 26 is placed directly above the inner space of the second plug-in tube 24. The water collection and storage upper tank 2 can be connected to multiple water collection devices, and the installation and distribution are flexible. When water is needed, the second semicircular cover plate 23 at the upper end of the water collection and storage upper tank 2 is flipped open, and water can be pumped out using a water pump. It provides convenience for watering landscaping, flushing and cleaning roads, and achieves the overall goal of saving water resources and being green and environmentally friendly.

[0037] In order to prevent the second joint 26 where the water pipe 3 is not installed from entering with dirt and other debris to pollute the water in the water storage tank 1 , a wooden plug is installed at the outer end of the second joint 26 where the water pipe 3 is not installed.
