The following describes the specific working procedure of the elevated road environment-friendly rainwater treatment system for sponge city according to the embodiment of the present application with reference to the above embodiments:
when not raining:
the first expansion block 504 in the filter box 300 extends out of the first groove 306 under the action of the third elastic member (not shown in the figure), the first filter plate 500 is in an initial state under the action of the first expansion block 504, the second expansion block 604 extends out of the second groove 308 under the action of the fourth elastic member (not shown in the figure), the first movable plate 600 is in an initial state under the action of the first expansion block 504, and the baffle ring 505 on the first filter plate 500 is in the mesh on the first movable plate 600, so that the first movable plate 600 is equivalent to a water-proof plate without meshes, and a water storage cavity capable of storing water is formed between the first filter plate 500 and the first movable plate 600. The inlet of the sediment collection tank 803 is blocked by the sliding plate 910 in a closed state, the movable frame 700 is in an initial state under the action of the fifth elastic member, so that the first top column 701 is far away from the hole of the first filter plate 500, and the second movable plate 920 is in an initial position under the action of the sixth elastic member in the transverse chute 310, so that the second top column 921 is far away from the water through hole of the partition 304 of the suspended matter collection tank 303. The hinged plate 802 on the second filter plate 800 is in the same plane as the second filter plate 800, so that the sediment collection tank 803 under the second filter plate 800 is in a closed state.
When it rains slightly:
the water flow of the drainage pipe 200 is small, the water flow enters the filter box 300 through the water inlet 301, the water flow is insufficient to overcome the friction force of the first elastic piece 502 and the first telescopic block 504 on the first filter plate 500, the water flow passes through the first filter plate 500, suspended matters filtered by the first filter plate 500 are temporarily placed on the first filter plate 500, the rainwater passing through the first filter plate 500 enters the first movable plate 600, the rainwater cannot pass through the first movable plate 600 because the meshes on the first movable plate 600 are blocked by the baffle ring 505 of the first filter plate 500, the water storage cavity formed between the first filter plate 500 and the first movable plate 600 starts to store water until the weight of the water stored on the first movable plate 600 overcomes the elastic force of the second elastic piece 602 on the first movable plate 600 and the friction force of the second telescopic block 604, the first movable plate 600 starts to slide downwards so that the meshes on the first movable plate 600 are separated from the baffle ring 505 of the first filter plate 500, and the water stored on the first movable plate 600 is discharged through the meshes, and simultaneously the first movable plate 600 slides downwards to drive the slide plate 500 to open the suspended matters to drain into the suspended matters collecting box 303. The water discharged from the first movable plate 600 passes through the second filter plate 800, and the sediment on the second filter plate 800 is accumulated above the sediment collecting box 803, when the sediment is accumulated to a certain amount, the sediment overcomes the elasticity of a seventh elastic element (not shown in the figure) between the hinge rod 801 and the hinge plate 802, and then the hinge plate 802 rotates downwards with the hinge rod 801 as an axis, so that the sediment collecting box 803 is opened, and the accumulated sediment enters the sediment collecting box 803.
When heavy rain is applied:
the water flow in the drainage pipeline 200 is larger, the water flow enters the filter box 300 through the water inlet 301, the water flow entering the filter box 300 is larger, the water flow directly acts on the first filter plate 500, the water flow overcomes the elasticity of the first elastic piece 502 on the first filter plate 500 and the friction force of the first telescopic block 504, the first filter plate 500 slides downwards, the sliding plate 910 is driven to slide downwards, the suspended matter collecting box 303 is opened, suspended matters filtered by the first filter plate 500 enter the suspended matter collecting box 303, the first filter plate 500 slides downwards, the baffle ring 505 is separated from the sealing fit of the meshes, the rainwater passing through the first filter plate 500 flows through the second filter plate 800 through the meshes of the first movable plate 600, sediment filtered by the second filter plate 800 is accumulated above the sediment collecting box 803, after the weight of the accumulated sediment overcomes the elasticity of the seventh elastic piece between the hinge rod 801 and the hinge plate 802, the hinge plate 802 rotates downwards by taking the hinge rod 801 as an axis, the hinge plate 803 is opened, and the accumulated sediment collecting box 803 enters the sediment collecting box 803.
The cleaning process comprises the following steps:
the rainwater flowing through the second filter plate 800 flows through the propeller 900, the water flow drives the propeller 900 to rotate, the propeller 900 rotates to drive the threaded rod 702 to rotate, and the threaded rod 702 rotates to drive the movable frame 700 to slide up and down in the sliding groove 311 because the threaded rod 702 is in threaded connection with the movable frame 700, so that the first jacking column 701 on the movable frame 700 guides and stretches out and draws back in the hole on the first filter plate 500, and suspended matters blocking the first filter plate 500 are cleaned. The up-and-down movement of the movable frame 700 drives the second movable plate 920 contacted with the movable frame 700 to slide in the transverse sliding groove 310 along the extending direction of the sliding groove, so that the second top column 921 on the second movable plate 920 guides and stretches in the water through hole of the partition plate 304 of the suspended matter collecting box 303, and further cleans suspended matters blocking the water through hole of the partition plate 304, and prevents the suspended matters from blocking the water through hole.
