Drainage structure in sponge city

Technical Field

The application relates to the field of drainage structures, in particular to a drainage structure of a sponge city.

Background

The sponge city is a new generation of city rainfall flood management concept, and refers to a city which can be like a sponge and has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and the city can also be called as a water elasticity city. When raining, the rainwater can absorb water, store water, seep water and purify water, and the stored water is released and utilized when needed, so that the rainwater can freely migrate in the city. However, rainwater is collected in a centralized manner after forming water flow on the ground and needing to be guided to a certain extent, so that the drainage structure is an essential water treatment device in a sponge city.

In the prior art, the drainage structure is usually connected with a municipal drainage pipeline, and a filter screen is added in the drainage structure. After the water flow on the ground enters the drainage structure, impurities in the water flow are filtered by the filter screen, and then the water flow enters the municipal drainage pipeline to be collected or treated in a centralized manner.

In view of the above-mentioned related technologies, the inventor thinks that the water flow often carries solid waste pollutants, and the solid waste pollutants on the filter screen are not easy to be cleaned due to the effect of the water flow, and are easy to pollute water resources.

Detailed Description

The embodiment of the application discloses drainage structures in sponge city. Referring to fig. 1, a drainage structure of a sponge city includes a filter tank 1, a material collecting tank 2 and a material leaking channel 3. The filter tank 1 is used for filtering water flow, and the material leakage channel 3 is used for allowing solid waste pollutants and other impurities to fall into the material collection box 2 from the filter tank 1. The material collecting box 2 is used for temporarily storing solid waste pollutants and other sundries, workers regularly clean the material collecting box 2, the solid waste pollutants and other sundries are classified and processed, the pollution of the solid waste pollutants to water resources is reduced, and the method is green and environment-friendly.

Referring to fig. 2, the upper end of the filter tank 1 is provided with a water inlet pipe 11 for water inlet, and the lower end of the filter tank 1 is provided with a water outlet pipe 12 for water outlet. Rainwater in a city enters the interior of the filter box 1 from the water inlet pipe 11 and then is discharged out of the filter box 1 from the water outlet pipe 12. The inside of rose box 1 is equipped with clearance piece 15 and filter 13, and clearance piece 15 is arranged in promoting the debris on the filter 13 to leaking in the material passageway 3. The cleaning part 15 comprises a shaft rod 151 which is rotatably connected with the filter box 1 through a bearing, the shaft rod 151 is horizontally arranged, and the axial lead of the shaft rod 151 is positioned between the axial leads of the material leakage channel 3 and the water inlet pipe 11. The outer peripheral surface of the shaft rod 151 is connected with a plurality of material pushing plates 152, and after the water flow in the water inlet pipe 11 enters the filter box 1, the water flow falls on the material pushing plates 152 because the shaft rod 151 is positioned at one side close to the material leaking channel 3. The pusher plate 152 is driven by the impact force of the water flow and its own gravity to rotate the shaft 151, thereby driving the entire cleaning member 15 to rotate.

Referring to fig. 2, the filter plate 13 is provided with a plurality of filter holes 14, and the filter plate 13 is configured as an arc-shaped plate. The filter plate 13 is bent toward the outlet pipe 12, and the bending radius of the filter plate 13 is equal to the radial length of the pusher plate 152 along the shaft 151. Solid waste pollutants and other impurities in the water flow are filtered by the filter plate 13 and are retained on the filter plate 13. After the material pushing plate 152 rotates, the solid waste pollutants and other impurities on the filter plate 13 are pushed into the material leaking channel 3.

Referring to fig. 2, the material leaking channel 3 is obliquely arranged, and the height of the material leaking channel 3 near one end of the filter box 1 is higher than the height of the material leaking channel 3 near one end of the material collecting box 2.

Referring to fig. 2, a box door 21 is rotatably connected to one side of the material collecting box 2, and a drain pipe 22 is connected to the lower end of the material collecting box 2. Two vertical inner walls of the material collecting box 2 opposite to each other are provided with first limiting convex edges 24, and first limiting grooves 25 are formed in the first limiting convex edges 24. The height of the first limiting convex edge 24 is lower than that of the end of the material leaking channel 3 close to the material collecting box 2. The first filter screen 23 is slidably disposed in the first limiting groove 25.

Referring to fig. 2, a second limiting rib 27 connected with the vertical inner wall of the material collecting box 2 is arranged below the first limiting rib 24, and a second limiting groove 28 is arranged in the second limiting rib 27. The second filter screen 26 is slidably disposed in the second limiting groove 28. The first filter 23 filters the water flow and impurities entering the material collecting box 2, the water flow enters the water discharging pipe 22, and solid waste pollutants and other impurities are remained on the first filter 23. The second filter 26 can improve the filtering effect, so that the solid waste pollutants are not easy to enter the drain pipe 22, and the water resource is polluted.

Referring to fig. 2, the lower end of the door 21 is lower than the second limiting groove 28, and the lower end of the door 21 is higher than the drain pipe 22 near the end of the material collecting box 2. The lateral wall of the material collecting box 2 below the box door 21 limits the water flow in the material collecting box 2, and the water flow is prevented from flowing out from the side surface of the material collecting box 2 to pollute the environment.

The implementation principle of the drainage structure of the sponge city in the embodiment of the application is as follows: the water flow carries impurities to enter the filter box 1 through the water inlet pipe 11, and the pushing plate 152 is driven by the pushing plate 152 to rotate to enable the cleaning piece 15 to rotate as the pushing plate 152 is hit by the water flow and the impurities. After the cleaning piece 15 rotates, the water flow contacts with the filter plate 13, and solid waste pollutants and other impurities in the water flow are retained on the filter plate 13 after being filtered by the filter plate 13. The subsequent water flow sequentially hits each material pushing plate 152, so that the material pushing plates 152 push the solid waste pollutants and other impurities along the surface of the filter plate 13, and then the solid waste pollutants and other impurities enter the material leaking channel 3. The solid waste contaminants and other impurities in the accept channel 3 fall by gravity onto the first filter screen 23 of the head box 2. The worker regularly cleans the first filter 23, and since the amount of water in the material collecting box 2 is smaller than that in the filter box 1, the impurities on the first filter 23 are more easily cleaned and recognized. The solid waste pollutant and other sundries can be classified and treated by workers conveniently, the pollution of the solid waste pollutant to water resources is reduced, and the method is green and environment-friendly.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
