A novel municipal road drainage structure's theory of operation:

when raining, rainwater flows into the drainage well 1 together with garbage such as garbage bags, stones, silt and the like from the water inlet hole 12 of the well lid 11. Firstly, rainwater flows into the primary filter tank 2, the primary filter tank 2 performs primary filtering on the rainwater, and at the moment, garbage such as garbage bags in the rainwater is filtered in the primary filter tank 2 under the action of the baffle rod 24. Then the rainwater flows out from the primary filter tank 2 and flows into the secondary filter tank 3, and the secondary filter tank 3 carries out secondary filtration with impurities such as stones and silt in the rainwater at this moment. Then the rainwater flows out from the secondary filter tank 3 and flows into the tertiary filter tank 4, and at the moment, the tertiary filter tank 4 deodorizes the peculiar smell in the rainwater under the action of the activated carbon. Finally, the rainwater flows out from the third-stage filter box 4 and flows to the bottom of the drainage well 1, and finally flows out of the drainage well 1 through the drainage pipe 13.

When needs clear up the rubbish in the drainage shaft 1, first step, the staff opens well lid 11 earlier, then at first rotates first hand wheel 51, first hand wheel 51 drives first lead screw 5 and rotates, first lead screw 5 drives fixed ear 25 and removes towards the direction that is close to the drainage shaft 1 opening end, fixed ear 25 drives one-level rose box 2 and removes towards the direction that is close to the drainage shaft 1 opening end, and when one-level rose box 2 removed to the opening end of drainage shaft 1, the staff dismantles first hand wheel 51 earlier, then takes out one-level rose box 2 from drainage shaft 1 through carrying hand ring 26.

When rubbish in the primary filter box 2 needs to be cleared up, the staff slides the driving box body 21 in the direction away from the passive box body 22, the driving box body 21 drives the T-shaped block 211 to slide in the direction close to the placing groove 221, and when the T-shaped block 211 is separated from the locking groove 222, the staff pulls the driving box body 21 in the direction away from the passive box body 22, the driving box body 21 drives the T-shaped block 211 to move in the direction away from the passive box body 22, at the moment, the T-shaped block 211 is separated from the placing groove 221, the driving box body 21 and the passive box body 22 are separated from each other, and at the moment, the staff can clear up the rubbish in the driving box body 21 and the passive box body 22.

The second step, the staff rotates second hand wheel 81 again, second hand wheel 81 drives second lead screw 8 and rotates, second lead screw 8 drives engaging lug 64 and removes towards the direction that is close to the drainage shaft 1 opening end, engaging lug 64 drives connector pole 61 and removes towards the direction that is close to the drainage shaft 1 opening end, connector pole 61 drives and supports daughter board 62 and the direction removal of second grade rose box 3 towards being close to the drainage shaft 1 opening end, and when second grade rose box 3 removed to the drainage shaft 1 opening end, the staff pulls down second hand wheel 81 earlier, then take out second grade rose box 3 and backup pad 6 through pull ring 31, clear up the rubbish in the second grade rose box 3 at last again.

When needing to overhaul secondary filter tank 3, the staff presses according to the piece 71 towards the direction that is close to support daughter board 62 earlier, presses according to piece 71 this moment and compresses tightly adjusting spring 73, and elasticity latch hook 63 breaks away from in butt groove 72, then the staff swings elasticity latch hook 63 towards the direction of keeping away from fixed cylinder 7 again, moves secondary filter tank 3 towards the direction of supporting daughter board 62 again at last, and secondary filter tank 3 breaks away from each other with backup pad 6 this moment, then overhauls secondary filter tank 3. When the maintenance is finished and the secondary filter box 3 is installed again, after the steps are repeated, a worker releases his hands to loosen the pressing block 71, the adjusting spring 73 is restored to a natural state, the adjusting spring 73 drives the pressing block 71 to move towards the direction away from the supporting sub-plate 62, the elastic locking hook 63 is hooked in the abutting groove 72 at the top of the pressing block 71, and the secondary filter box 3 is fixed on the supporting plate 6.

To sum up, the staff clears up the rubbish in first order rose box 2 and the second grade rose box 3 respectively, is favorable to clearing up the rubbish in the drainage shaft 1.

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.
