And a second stage: when raining, rainwater flows into the device from a road and a sidewalk in a flood way, firstly, the rainwater enters the device through the well cover 2, the well cover 2 can primarily intercept large-size muck carried in the rainwater, the rainwater after the muck blocking enters the well chamber 1, firstly, the rainwater enters the water passing chamber 5, flows into the first sub-diversion chamber 12 in the middle of the well chamber 1 through the water flowing port 8 on the upper baffle plate 3, firstly flows through the muck opening 9 before entering the first sub-diversion chamber 12, the muck in the rainwater falls into the muck catcher 10, a small part of the rainwater flows into the first water filling box 23 through the first water filling pipe 22, the water filling box 23 is filled with water, meanwhile, the rainwater in the first water filling box 23 is discharged into the intercepting pipe 15 corresponding to the first sub-diversion chamber 14 through the first water draining pipe 24 in a drip pipe draining mode, and finally, the rainwater is discharged into the corresponding municipal pipeline; most of the rainwater is discharged into the first sub-intercepting chamber 14 through the first water discharge orifice 7 of the middle baffle 4, and finally is discharged into the corresponding municipal rainwater intercepting pipe through the intercepting pipe 15 corresponding to the first sub-intercepting chamber 14. Since the water amount filled into the first water filling tank 23 through the first water filling pipe 22 is larger than the dripping and draining amount of the first water draining dropper 24, the first water filling tank 23 is slowly filled, and in the process, the first water filling tank pulls the first lower spring 19 under the action of self gravity to further drive the first upper cover plate 18 and the first lower cover plate 21 to move downwards, so that the first upper cover plate 18 covers the first water draining hole 7, and meanwhile, the first lower cover plate 21 drives the first pulling piece 20 to pull the first blocking plate 25 to move downwards until penetrating the first yielding hole 26 on the middle baffle plate 4, so that the notch at the lower end of the first upper baffle plate 28 is gradually and completely opened; when the accumulated rainfall reaches a set value, the first water filling tank 23 is filled with rainwater, and at the moment, the upper end of the first plugging plate 25 is not lower than the lower surface of the middle baffle 4.
And a third stage: at this time, the first water-filling tank 23 is still filled with a small portion of rainwater through the first water-filling pipe 22 and drained through the first water-draining drop pipe 24, but the total amount of rainwater flowing in and out is balanced, the first water-filling tank 23 is kept full, and most of the rainwater does not enter the first sub-intercepting chamber 14 through the first water-draining hole 7 on the middle baffle 4, but enters the second sub-intercepting chamber 12 through the notch at the lower end of the opened first upper baffle 28, and the operation similar to that of the rainwater in the first sub-intercepting chamber 12 is also performed in the sub-intercepting chamber, that is, most of the rainwater is discharged into the second sub-intercepting chamber 14 through the second water-draining hole 7 and finally discharged into the corresponding municipal rainwater intercepting pipe through the second intercepting pipe 15. Since the water amount filled into the second water filling tank 23 through the second water filling pipe 22 is larger than the dripping and draining amount of the second water draining dropper 24, the second water filling tank 23 is slowly filled, in the process, the second water filling tank 23 is filled with rainwater, at the moment, the second water filling tank pulls the second lower spring 19 under the action of self gravity to further drive the second upper cover plate 18 and the second lower cover plate 21 to move downwards, so that the second upper cover plate 18 covers the second draining hole 7, and meanwhile, the second lower cover plate 21 drives the second pulling piece 20 to pull the second plugging plate 25 to move downwards until passing through the second yielding hole 26 of the middle baffle plate 4, so that a notch at the lower end of the second upper baffle plate 28 is gradually and completely opened; when the accumulated rainfall reaches a set value, the second water filling tank 23 is filled with rainwater, and the upper end of the second plugging plate 25 is not lower than the lower surface of the middle baffle 4.
Fourth stage: at this time, the first water filling tank 23 and the second water filling tank 23 still have a small part of rainwater filled through the first water filling pipe 22 and the second water filling pipe 22 respectively, and drain through the first water draining dropper 24 and the second water draining dropper 24 respectively, but the total amount of rainwater entering and exiting is balanced, the first water filling tank 23 and the second water filling tank 23 keep full, most of rainwater does not enter the first intercepting chamber 14 and the second intercepting chamber 14 through the first water draining orifice 7 and the second water draining orifice 7 on the middle baffle 4 respectively, but enters the third intercepting chamber 12 through the notch at the lower end of the first upper baffle 28 and the second upper baffle 28 in sequence, and the operation similar to the operation of the first intercepting chamber and the second intercepting chamber 12, namely, most of rainwater enters the third intercepting chamber 14 through the corresponding intercepting pipe 14 through the third intercepting pipe 14, is also carried out in the sub-dividing chamber. Since the water amount filled into the third water filling tank 23 through the third water filling pipe 22 is larger than the drip amount of the third water discharging dropper 24, the third water filling tank 23 is slowly filled, in the process, the third water filling tank 23 is filled with rainwater, at the moment, the third water filling tank is pulled by the self gravity to further drive the third lower spring 19 to move the third upper cover plate 18 and the third lower cover plate 21 downwards, so that the third upper cover plate 18 covers the third water discharging hole 7, and meanwhile, the third lower cover plate 21 drives the third pulling piece 20 to pull the third blocking plate 25 downwards until passing through the third position yielding hole 26 of the middle baffle plate 4, so that the notch at the lower end of the third first upper baffle plate 11 is gradually and completely opened; when the accumulated rainfall reaches a set value, the third water filling tank 23 is filled with rainwater, and at the moment, the upper end of the third plugging plate 25 is not lower than the lower surface of the middle baffle 4. At this time, the first water filling tank 23, the second water filling tank 23 and the third water filling tank 23 still have less part of rainwater filled through the first water filling pipe 22, the second water filling pipe 22 and the third water filling pipe 22 respectively, and simultaneously drain through the first water draining dropper 24, the second water draining dropper 24 and the third water draining dropper 24 respectively, but the total amount of the rainwater entering and exiting is balanced, the first water filling tank 23, the second water filling tank 23 and the third water filling tank 23 keep full, most of the rainwater does not enter the first water draining hole 7, the second water draining hole 7 and the third water draining hole 7 on the middle baffle 4 into the first water intercepting chamber 14, the second water intercepting chamber 14 and the third water intercepting chamber 14 respectively, but sequentially enters the water draining pipe 6 through the opened first upper partition 28, the second upper partition 28 and the second water intercepting chamber 28 into the water draining pipe 6 at the corresponding water draining hole 27.
Fifth stage: after the rain is stopped, the first water filling pipe 22, the second water filling pipe 22 and the third water filling pipe 22 do not fill the first water filling tank 23, the second water filling tank 23 and the third water filling tank 23 respectively, the first water discharging dropper 24, the second water discharging dropper 24 and the third water discharging dropper 24 continue water discharging, the first water filling tank 23, the second water filling tank 23 and the third water filling tank 23 are respectively emptied gradually, in the process, the first upper spring 17, the second upper spring 17, the third upper spring 17 are respectively reset upwards due to the restoring tension, in the process, the first upper cover plate 18 and the first lower cover plate 21, the second upper cover plate 18 and the second lower cover plate 21, the third upper cover plate 18 and the third lower cover plate 21 respectively move gradually, the first upper cover plate 18, the second upper cover plate 26, the third upper cover plate 26 and the third upper cover plate 26 respectively move gradually, the first upper cover plate 18, the second upper cover plate 7, the third cover plate 21, the third cover plate 20 and the third cover plate 20 are respectively pulled gradually, the second cover plate 26 and the third cover plate 20 are respectively opened gradually, the first upper cover plate 21, the third cover plate 20 and the third cover plate 20 are respectively opened gradually, the second cover plate 20 and the third cover plate 20 are respectively, and the third cover plate 20 is respectively opened gradually, and the drain is respectively opened gradually, and the first upper cover plate is opened, and the second cover plate is opened, and the third cover plate is opened, and the second cover plate is opened, and the drain is opened, and a third drain is a drain is opened, and a drain, the notch at the lower end of the second upper partition 28 and the first upper partition 11 is gradually completely blocked.
