Description

Technical Field

[0001] The present invention relates to the technical field of urban rainwater treatment, and in particular to a sponge city rainwater collection and treatment device. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "resilience" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called a "water-resilient city". The internationally accepted term is "low-impact development rainwater system construction". It absorbs, stores, infiltrates and purifies water when it rains, and "releases" and utilizes the stored water when needed. The construction of sponge cities should follow the principles of ecological priority, combine natural approaches with artificial measures, and maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and flood prevention, promote the utilization of rainwater resources and the protection of the ecological environment. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, and all aspects of water recycling such as water supply and drainage should be coordinated, and its complexity and long-term nature should be considered.

[0003] The most convenient way to collect urban rainwater is to collect it in roadside sewers. However, the accumulated fallen leaves, garbage and other debris on the sewer covers will cause blockage of the sewers and affect the speed at which rainwater is discharged downward, causing the water level on the road to rise. In addition, the existing sewers will not remove impurities, particles and bacteria in the rainwater, making it impossible to use the collected rainwater directly. Summary of the Invention

[0037] In the present invention, vertical rods 9 are fixedly connected to both sides of the bottom of the top plate 1, and movable plates 10 are fixedly connected to the opposite sides of the two processing boxes 41. The interior of the movable plates 10 is slidably connected to the surface of the vertical rods 9.

[0038] Specifically, the vertical rod 9 and the movable plate 10 are provided to provide a certain stability for the movement of the processing box 41 .

[0039] In the present invention, a second chute 11 adapted to the slide plate 59 is provided on the top of the top plate 1 , and silicone rods 12 are fixedly connected to both sides of the inner wall of the second chute 11 .

[0040] Specifically, the silicone rod 12 has a certain degree of flexibility. When the slide 59 moves, it can move freely from the inside of the second slide groove 11. The silicone rod 12 will fold or bend under the movement of the slide 59 and will not cause obstruction. The setting of the silicone rod 12 is to prevent debris from directly entering the interior of the fixed frame 3 from the second slide groove 11, and play a certain role in blocking debris.

[0041] In the present invention, a through hole 13 is opened at the bottom of the inner frame 7, and the top and bottom between the surface of the inner frame 7 and the inner wall of the protective frame 6 are fixedly connected with a first filter screen 14, and a first filter material 15 is arranged between the opposite sides of the two first filter screens 14.

[0042] Specifically, the first filter material 15 is a quartz sand filter material, which can be replaced. The particle size of the quartz sand filter material is larger than the mesh diameter of the first filter screen 14 .

[0043] In the present invention, water outlet holes 16 are provided at the tops of both sides of the protective frame 6, and second filter screens 17 are fixedly connected to the top and bottom between the surface of the protective frame 6 and the inner wall of the fixed frame 3, a second filter material 18 is provided between the opposite sides of the two second filter screens 17, and water outlet buckets 19 are fixedly connected to both sides of the bottom of the fixed frame 3.

[0046] Specifically, the retractable brush 25 is provided to process the debris dropped on the protective cover 2 or to push it to the periphery of the protective cover 2 to prevent the impurities from causing the rainwater to flow in poorly.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] When in use, the device is placed under the sewer outlet, and the limit plate 8 limits the device as a whole so that the protective cover 2 is flush with the ground. When it rains, the electric telescopic rod 20 is started by the external switch, and the electric telescopic rod 20 drives the horizontal plate 21 to rise, and the horizontal plate 21 drives the vertical plate 22 to move upward, pushing the processing box 41 to move upward, so that the through slot 42 on the processing box 41 exceeds the height of the top plate 1. At this time, the motor 52 is started, and the motor 52 drives the first movable rod 53 to rotate. When the gear 55 rotates, it is in meshing with the tooth plate 57. When the worm gear 412 is in the state, it will rotate and move on the tooth plate 57, thereby driving the scraper 51 to move on the top plate 1 as a whole, and the gear 55 on the second movable rod 54 will also rotate together. The slide plate 59 moves inside the top plate 1, and the threaded rod 510 connected to the internal thread of the slide plate 59 rotates under the movement of the slide plate 59, driving the worm gear 412 to rotate. The worm sleeve 44 engaged with the worm gear 412 will drive the cross bar 43 to rotate, and the scraper 51 moves left and right, pushing the debris on the top of the top plate 1 into the inside of the processing boxes 41 on both sides;

[0049] Debris enters the processing box 41 through the through slot 42 on the processing box 41. The rotation of the crossbar 43 drives the blade 45 to rotate, crushing the debris that falls into the processing box 41. Under the transmission action of the pulley 48 and the belt 49, the screw 46 drives the extrusion plate 47 to move left and right, squeezing the crushed debris that falls on the filter plate 410 to reduce its volume. The water filtered by the filter plate 410 enters the interior of the fixed frame 3 through the hose. The rotation of the first movable rod 53 and the second movable rod 54 drives the turbine blade 58 to rotate, and the rainwater entering the inner frame 7 through the first chute 56 rotates, causing it to be discharged in a vortex shape, accelerating its flow rate.

[0050] Rainwater enters between the protective frame 6 and the inner frame 7 through the through hole 13, and after being filtered by the first filter material 15, flows from the water outlet 16 to between the fixed frame 3 and the protective frame 6, and after being filtered by the second filter material 18, is discharged from the water outlet 19 at the bottom of the fixed frame 3.
