Description

Technical Field

[0001] The invention relates to the technical field of drainage equipment, and in particular to a sponge city drainage structure with a water purification function. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and respond to natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". The internationally accepted term is "low-impact development rainwater system construction". It absorbs, stores, infiltrates and purifies water when it rains. When needed, the stored water is released and utilized to achieve the free migration of rainwater in the city. Starting from the ecosystem service, the water ecological infrastructure is constructed across scales and combined with a variety of specific technologies to build water ecological infrastructure. It is the core of the sponge city and effectively alleviates the urban heat island effect, so that the urban road surface no longer heats up.

[0003] A road drainage device for preventing blockage in sponge cities disclosed in the Chinese invention patent application disclosure specification CN213625959U includes a water inlet device and a waste collection bucket, the lower surface of the water inlet device is provided with an inclined deflector cover, the lower surface of the inclined deflector cover is provided with a square duct, the square duct is fixedly connected to a mounting bracket plate, the square duct is slidably connected to a filter screen, and a waste pushing device is provided on one side of the waste collection bucket. The road drainage device for preventing blockage in sponge cities effectively filters out larger solid particles through the filter screen to avoid blockage of waterways. At the same time, solid garbage or sludge passing through the filter screen will be deposited in the waste collection bucket, and can be discharged under the action of the waste pushing device, further preventing blockage of waterways, thereby improving the ability to collect wastewater and drain water.

[0004] A road drainage device for a sponge city disclosed in the Chinese invention patent application publication specification CN211171485U includes a drainage device, a mounting plate is arranged at the upper end of the drainage device, the drainage device is composed of a waterway and a waste box, a water inlet is arranged on the upper side of the waterway, a garbage outlet is arranged on the upper side of the waste box, a curved pipe is arranged inside the waterway, the upper end of the curved pipe is welded at the water inlet at the upper end of the waterway, a filter screen is arranged at the bottom end of the middle arc section of the waterway, the filter screen is welded on the upper side of the curved pipe, the bottom end of the curved pipe extends into the middle position of the waste box, the curved pipe is connected with the waste box, and the curved pipe is welded on the upper side of the waste box. After the water enters the water inlet, it first flows into the curved pipe, and the filter screen at the bottom end of the curved pipe will filter the solid garbage in the water, and the filtered garbage will be introduced into the waste box along the water flow to prevent large garbage from entering the waterway and causing waterway blockage.

[0005] However, in the above-mentioned Chinese invention patents, there is a problem that it is inconvenient for personnel to disassemble the internal components. After long-term use, the internal components are prone to wear and deformation, resulting in reduced filtering effect on impurities in rainwater and shortening the overall service life of the equipment.
