Detailed Description
The invention will be further elucidated and described with reference to the embodiments and drawings of the specification:
referring to fig. 1, a municipal road rainwater filtration system includes a collection unit 10, a filtration unit 20, an application unit 30, a lifting pipeline 51, and a back-flushing pipeline 52 and a return pipeline 53. Meanwhile, it should be noted that the system mentioned in this embodiment is a medium-small system, and is built in a city in a distributed manner.
The collecting unit 10, the filtering unit 20 and the applying unit 30 are connected in sequence.
The collection unit 10 includes a plurality of road drainage mechanisms 11, a plurality of settling wells 12, a rainwater collection tank 13, and a flood discharge line 14. The road surface drainage mechanism 11 is embedded in the road surface, and the sedimentation well 12 and the rainwater collecting tank 13 are sequentially and deeply buried underground.
Referring to fig. 2, the pavement drainage mechanism 11 includes a manhole cover grate 111, a "y" drainage channel 112, a plurality of fixed shafts 114, a plurality of "V" buffer flow plates 115, a connecting rod 116, and a blocking elastic member 117. The fixed shafts 114 are sequentially fixed on the side wall of the y-shaped drainage channel 112, and a cavity 113 is formed on the adjacent side wall of the y-shaped drainage channel 112. The number of the fixed shaft 114 is the same as that of the V-shaped flow delaying plates 115, the middle part of the V-shaped flow delaying plates 115 is rotatably connected to the fixed shaft 114, so that the V-shaped flow delaying plates 115 can rotate around the fixed shaft 114, and meanwhile, one part of the V-shaped flow delaying plates 115 is arranged in the y-shaped drainage channel 112, and the other part of the V-shaped flow delaying plates 115 is arranged in a cavity 113. The V-shaped buffer plates 115 arranged in the cavity 113 are rotatably connected with the connecting rods 116, and two ends of the blocking elastic piece 117 are respectively fixed on the connecting rods 116 and the inner wall of the cavity 113. When the rainfall is in a medium or small scale, the V-shaped buffer plate 115 can buffer the entering rainwater in a blocking way. So as to prevent the rapid flow entering from forming vortex or turbulent water flow and improve the stability of the system. When heavy rainstorm occurs, collection is carried out according to the principle of rapid dispersion. In combination with the impact force of the rapid water flow, the "V" shaped baffle 115 is pressed and attached to the inner wall of the "y" shaped drainage channel 112, and the rotating fixed shaft 114 lifts the connecting rod 116 to drive the blocking elastic member 117 to extend. The stiffness coefficient of the blocking elastic member 117 in this embodiment is determined by the impact force generated by the amount of rainwater entering the manhole cover grate 111 per unit time in heavy rain. When the rainfall is reduced to the middle rain level, the elastic piece 117 is hindered to contract and pull the connecting rod 116 to move, and then the V-shaped slow flow plate 115 is driven to rotate and lift a part of the V-shaped slow flow plate 115, which is arranged in the y-shaped drainage channel 112, so that the rainwater is rectified again.
The y-shaped drainage channel 112 of each road drainage mechanism 11 in the embodiment is correspondingly communicated with the top of one settling well 12. An interconnected water inlet pipe 131 is arranged between the settling well 12 and the rainwater collecting tank 13, and the flood discharge pipeline 14 is communicated with the bottom of the rainwater collecting tank 13. A pressing flood discharge mechanism 40 is arranged between the rainwater collecting tank 13 and the flood discharge pipeline 14.

The end part of the pressing valve 41 is fixed with the door shaft 42, the two ends of the door shaft 42 are rotatably connected to the top of the flood discharge pipeline 14, the two ends of the first rod body 43 are rotatably connected with the pressing valve 41 and the connecting rod 45, the middle rotating shaft 44 is rotatably connected to the top of the flood discharge pipeline 14 in an embedded mode, the rod body of the connecting rod 45 is rotatably connected with the middle rotating shaft 44, the two ends of the connecting rod 45 are arranged on the inner side and the outer side of the flood discharge pipeline 14, the other end of the connecting rod 45 is rotatably connected with the second rod body 46, the fixing plate 47 is arranged on the outer wall of the top of the flood discharge pipeline 14, and the two. Specifically, the stiffness coefficient of the elastic member 48 is set according to a preset threshold of the amount of rainwater received by the rainwater collection tank 13.
When extreme weather, i.e. heavy rainfall, is encountered, the rainwater in the rainwater collecting tank 13 will quickly reach a saturated state. At this time, the pressure at the bottom of the rainwater collecting tank 13 will reach the limit value, so the rainwater will push the pressing valve 41 to rotate, the pressing valve 41 will push the connecting rod 45 to rotate around the central rotating shaft 44 through the first rod 43, and the rotating connecting rod 45 will drive the elastic member 48 to extend through the second rod 46. At the moment, excessive rainwater is discharged into a surrounding water system from the inside of the system, so that the excessive rainwater is prevented from impacting the system, and the overall stability of the system is finally ensured. When the amount of rainwater in the rainwater collection pool 13 drops to a preset threshold value, the elastic member 48 recovers to a natural state, the second rod 46 is pulled to move backwards, the connecting rod 45 is rotated to push the first rod 43 to move forwards, and finally the first rod 43 pushes the pressing valve 41 to separate the rainwater collection pool 13 from the flood discharge management 14. The system can directly and quickly process the impact problem of excessive rainwater on the system through a non-electronic means, and the stability of the system is improved, so that the construction cost of the system is relatively reduced. Meanwhile, the system does not depend on layer-by-layer filtration of the mountain, and is very suitable for most cities.
Preferably, the length of the rod body of the connecting rod 45 arranged inside the flood discharge pipeline 14 is less than the length of the rod body of the connecting rod 45 arranged outside the flood discharge pipeline 14. By using the lever principle, the power generated by the elastic member 48 can be reduced by extending the length of the external connecting rod 45 of the flood discharge pipeline 14, so that the service life of the elastic member 8 can be prolonged, and the stability of the whole system can be improved.
Preferably, the middle parts of two adjacent settling wells 12 are provided with a communicating pipeline 121, so that overload of part of systems caused by heavy rainfall weather in part of urban areas is avoided. When a part of the area is exposed to heavy rainfall weather, the settling well 12 distributes rainwater into the adjacent settling well 12 to relieve the pressure of the settling well. And then a plurality of systems in the whole city are communicated to relieve the rainwater collection pressure in partial areas.
Referring to fig. 4, the water inlet pipe 131 is disposed at a tenth of the bottom of the settling well 12. Rainwater will flow into the rainwater collecting tank 13 through the water inlet pipe 12, and sediment precipitation mixed in the rainwater is precipitated to the bottom of the precipitation well 12. The end of the water inlet pipe 131 connected with the settling well 12 is provided with a filter screen 1311, and the end face of the end is inclined, and the inclined end face points to the inclined lower part of the settling well. Carry out prefiltration to the rainwater through filter screen 1311, and the silt that is blockked will receive in self the reason sink to the bottom of sediment well 12, cut the inlet tube 131 design of inclined end face, then effectively avoided the silt of whereabouts to adhere to and hinder the entering of rainwater on filter screen 1311.

And the part of the lifted rainwater flows back into the rainwater collecting tank 13 again, so that the impurities in the inner part are precipitated into the rainwater collecting tank 13.
A purifying device 21 is arranged between the filtering unit 20 and the application unit 30, and the rainwater filtered by the filtering unit 20 enters the application unit 30 through the purifying device 21. The purification device 21 is embodied as an ultraviolet sterilizer. The filtered rainwater is further purified by the purification device 21, killing microorganisms contained therein.
