When it is not raining, the floating ball 23 in the inlet chamber 1 is pulled by its own gravity to pull the connecting line 22 to be in a release state, the pulley 21 is pulled by the connecting line 22 to be in an initial state, the corresponding torsion spring 24 is also in an initial state, the telescopic inlet pipe 34 of the drainage mechanism 17 is in a naturally drooping state, the gate plate 37 does not cover the drainage port of the drainage pipe 5, and the drainage port of the drainage pipe 5 is in an open state.

When raining, rainwater on the road surface flows from the road and the sidewalk to the device in a overflowing way, firstly enters the device through the water permeable well cover 10, the rainwater enters the water inlet chamber 1 through the water permeable well cover 10, and fills the water into the square tube 35 through the telescopic inflow tube 34, at the same time, the water is drained through the drainage holes in the square tube 35, but because the water filling amount is far larger than the drainage amount, the square tube 35 and the telescopic inflow tube 34 are quickly filled, due to the self gravity of the rainwater in the water inlet chamber, the telescopic inflow tube 34 is pulled downwards, the gate 37 is driven by the connecting rod 36 to close the drainage port of the drainage pipe 5, after the drainage pipe 5 is closed, rainfall continues, the rainwater flowing into the device enables the water level of the water inlet chamber 1 and the water through chamber 2 to rise, the water level of the water inlet chamber 1 can rise to float 23, and the connecting wire 22 is driven to move upwards and wind on the pulley 21, the pulley 21 is driven to rotate in the winding process, the torsion spring 24 is twisted in the rotation process of the pulley 21 to drive the rotating rod 25 to rotate, the rotating rod 25 rotates to drive the water outlet rotary disc 15 in the water passing chamber 2 to rotate, the rotating rod 25 rotates to drive the worm 19 to rotate at the same time, the worm 19 drives the turbine 18 to rotate through the meshing effect, the turbine 18 rotates to drive the rotating cylinder 26 to rotate, when the accumulated rainfall reaches a set value, the water levels of the water inlet chamber 1 and the water passing chamber 2 rise to corresponding set water levels, the water outlet rotary disc 15 rotates to a certain angle, at the moment, the hole 33 on the water outlet rotary disc 15 and the hole 32 with the lowest height on the longitudinal partition plate 12 are overlapped to form a water passing hole, and other holes 32 are blocked by the water outlet rotary disc 15 to prevent water from passing, at this time, the rainwater in the two water flowing chambers 2 respectively flow into the intercepting pipes 28 in the diversion chamber 3 from the corresponding water flowing ports, and are discharged from the water outlets of the two intercepting pipes 28 to form water flows perpendicular to each other and flow into the water outlet tank 27, the water flows in the two intercepting pipes 28 can form hydraulic cross-flow vortices to form a stirring effect, so that the silt in the rainwater is coagulated and settled, and the stirring blades 31 in the water outlet tank 27 stir the water in the water outlet tank 27 along with the rotation of the rotating cylinder 26 to further strengthen the coagulation and settlement of the silt in the rainwater. The settled silt sinks into the silt settling hopper 30, and the rainwater after settling is discharged through the water outlet pipe 29 and into a corresponding rainwater pipeline at the downstream; with the continuous increase of rainfall, the water levels of the corresponding water inlet chamber 1 and the corresponding water passing chamber 2 also continue to rise, the floating ball 23 continues to float in the rising process, and then the pulley 21, the torsion spring 24, the rotating rod 25, the water outlet rotary disc 15 and the like are sequentially driven to rotate by driving the connecting line 22, and in the rising process, the hole 33 on the water outlet rotary disc 15 is not overlapped with the hole 32 with the lowest height on the longitudinal partition plate 12 any more, so that a water passing hole is not formed any more; when the accumulated rainfall reaches another set value, the water levels of the water inlet chamber 1 and the water passing chamber 2 rise to another set water level (higher water level), the water outlet rotary disc 15 rotates to another angle, at this time, the hole 33 on the water outlet rotary disc 15 and the hole 32 with the second lower height on the longitudinal partition plate 12 are overlapped to form a water passing through port, the other hole 32 is blocked by the water outlet rotary disc 15, at this time, the rainwater in the two water passing chambers 2 respectively flow into the cut-off pipe 28 in the diversion chamber 3 from the corresponding water passing through port, and are discharged from the water outlets of the two cut-off pipes 28 to form mutually perpendicular water flows to flow into the water outlet tank 27, the water flows in the two cut-off pipes 28 can form hydraulic cross-flow vortex to form a stirring effect, so that silt in the rainwater is coagulated and settled, and the stirring piece 31 in the water outlet tank 27 forms a stirring effect on the water in the water outlet tank 27 along with the rotation of the rotary cylinder 26 And the silt in the rainwater is further strengthened by stirring and is condensed and settled. The settled silt sinks into the silt settling bucket 30, and the rainwater after settling is discharged through the water outlet pipe 29 and into a corresponding rainwater pipeline at the downstream; as the rainfall continues to increase, the water levels of the respective inlet and

outlet chambers

1, 2 also continue to rise, and a similar process as described above continues to occur.

After rainfall, no rainwater is injected into the telescopic inflow pipe 34 and the square tube 35, rainwater in the telescopic inflow pipe 34 and the square tube 35 is drained gradually through the drain hole in the square tube 35, in the process, the telescopic inflow pipe 34 gradually returns to an initial state due to the action of restoring force, the telescopic inflow pipe 34 pulls the connecting rod 36 upwards to drive the flashboard 37 to move upwards so as to open the drain port on the drain pipe 5, rainwater in the water inlet chamber 1, the water through chamber 2 and the communication chamber 4 is drained through the drain pipe 5, in the process, the floating ball 23 is not subjected to the buoyancy of the rainwater in the water inlet chamber 1 to pull the connecting wire 22 downwards under the action of gravity, so that the connecting wire 22 is released from the pulley 21 to pull the pulley 21, and the torsion spring 24, the torsion spring 21 and the torsion spring 21 are sequentially driven by the pulley 21, The rotating rod 25, the water outlet rotary disc 15, the worm 19, the worm wheel 18 and the like rotate to restore the initial state.

In the absence of rain, the watertight well cover 38 may be opened to remove the rotary drum 26, thereby removing the sediment from the sediment hopper 30.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
