When the polarity of the magnetic valve 52 is the same as that of the first magnetic block 53, the gate 51 can be opened, meanwhile, as a certain pressure is generated at the bottom of the gate 51 after the previous water storage, the pressure can further assist in opening the gate 51, so that the gate 51 can be turned over and opened at a larger speed, the water pressure of the water storage can drive the water flow to quickly enter the drainage cavity 12 to be discharged, the drainage efficiency is improved, the water flow can quickly enter the drainage outlet, when the gate 51 is turned over at a larger speed, the gate 51 can prop against the clapping baffle 823, so that the clapping baffle 823 moves in a direction away from the gate 51, the clapping baffle 822 can drive the second connecting circular pipe 823 to move in the first connecting circular pipe 821, the transverse reset spring 824 is compressed, the clapping baffle 823 can drive the two transverse moving toothed bars 825 to move in a direction away from the gate 51, the movement of the two transversely moving toothed bars 825 can drive the two first linkage gears 833 to rotate, the two first linkage gears 833 can drive the linkage rotating rods 832 to rotate, the linkage rotating rods 832 can drive the two second linkage gears 834 to rotate, the two second linkage gears 834 can respectively drive the two moving racks 842 to move upwards, the moving racks 842 can slide on the sliding vertical grooves 15 through the two moving sliding plates 841, the two moving racks 842 can drive the moving connecting plates 843 to move upwards, the moving connecting plates 843 can drive the cleaning plate brushes 844 to move upwards, the upward movement of the cleaning plate brushes 844 can clean the water level monitor 81, dust and dirt on the water level monitor 81 are washed cleanly, the dust and dirt on the water level monitor 81 are prevented from affecting the accuracy of water level detection, the water level monitor 81 is enabled to malfunction or lower in accuracy, and the detection efficiency and the detection accuracy are improved.

When the clapping baffle 823 moves in the direction away from the gate 51, the second magnetic attraction block 826 can be driven to move in the direction away from the gate 51, so that the second magnetic attraction block 826 is close to the magnetic ball 96, a repulsive force is generated between the second magnetic attraction block 826 and the magnetic ball 96 due to the fact that the polarity of the second magnetic attraction block 826 is opposite to that of the magnetic ball 96, the magnetic ball 96 can strike the inner side wall of the shell 10, so that the inner side wall of the shell 10 slightly vibrates, part of dust and dirt attached to the inner side wall of the shell 10 can be vibrated or loosened, then taken away by water flow, and the situation that the space in the drainage cavity 12 is reduced and the drainage efficiency is reduced due to long-term accumulation of the dust and the dirt on the inner side wall of the shell 10 is prevented.

When the shutter 51 abuts against the clapping plate 823 and enables the clapping plate 823 to move to the maximum distance in the direction away from the shutter 51, the shutter 51 is turned over to the maximum distance, the transverse reset spring 824 is compressed to the maximum distance at the moment, larger elastic force is generated by the transverse reset spring 824, the moving slide plate 841, the moving rack 842, the moving connecting plate 843 and the cleaning plate brush 844 have downward movement trend under the influence of self gravity, the auxiliary linkage 83 has the trend of reversing and driving the transverse moving toothed bar 825 to move towards the direction close to the shutter 51, the pressure of water flow to the shutter 51 is reduced due to the fact that the shutter 51 is turned over to the maximum distance, the repulsive force generated by the fact that the distance between the first magnetic block 53 and the magnetic valve 52 is larger is smaller, the shutter 823 is reset and pushed to turn over towards the direction of the magnetic valve 52 by combining the factors, when the shutter 51 is turned back to a certain distance, the distance between the first magnetic block 53 and the magnetic valve 52 is shortened, the repulsive force is changed to be large, and the opening of the shutter 51 is reduced, so that the water pressure is gradually increased, the shutter 823 is driven to move towards the direction close to the shutter 51 again, the direction of the shutter 823 is not to the opposite to the direction of the magnetic valve 52, the shutter 823 is moved towards the direction of the magnetic valve 823, and the reciprocating device 823 is not to be compressed, the shutter 823 is gradually and the opposite to the direction of the shutter is moved towards the direction of the shutter 51, and the shutter 823 is slightly, the opposite to the direction of the shutter 823 is moved, and the direction of the shutter is moved.

6. A roof rainwater regulation method for urban inland inundation defense, characterized in that the roof rainwater regulation device for urban inland inundation defense as claimed in claim 5 is applied, the method comprising the steps of:

step one: the roof rainwater regulation device for urban inland inundation defense is arranged at a roof water outlet, when a rainfall detection mechanism (70) detects that the roof is raining at present, a gate (51) is in a normally closed state, water starts to be stored at the water outlet of the roof, when a water level monitor (81) detects that the water level reaches a preset height, a controller (20) controls a magnetic valve (52) to generate opposite polarity, the gate (51) is opened, the water is discharged downwards from the roof water outlet through a water discharging cavity (12), and an operator can observe the opening and closing state of the gate (51) in real time through a communication mechanism (40) and an opening and closing detection mechanism (60);

step two: the gate (51) can prop against the clapping baffle (823) when being opened and turned over at a larger speed, so that the movable connecting plate (843) drives the cleaning scrubber (844) to move upwards to clean the water level monitor (81), the gate (51) can prop against the clapping baffle (823) to move reciprocally, and the reciprocating movement of the clapping baffle (823) can enable the cleaning scrubber (844) to clean the water level monitor (81) for multiple times;

Step three: when the clapping baffle plate (823) moves in a direction away from the gate (51), the second magnetic attraction block (826) is driven to move in a direction away from the gate (51), so that the magnetic ball (96) impacts the inner side wall of the shell (10), and the reciprocating movement of the clapping baffle plate (823) can enable the magnetic ball (96) to impact the inner side wall of the shell (10) for a plurality of times;

step four: when the water level rises to the position above the overflow port (16), water flow can impact the drainage floating plate (92), so that the drainage floating plate (92) is gradually overturned, the rotation connecting plate (93) can be driven to overturne and move when the drainage floating plate (92) overturns, the rotation connecting plate (93) can drive the adjusting slide block (94) to move, the movement of the rotation connecting plate (93) can also drive the connecting elastic rope (95) to move upwards, and the connecting elastic rope (95) can drive the magnetic ball (96) to move upwards;

step five: when the rainfall detection mechanism (70) detects that the rainfall stops, and the water level reaches the requirement, the magnetic valve (52) generates polarity opposite to that of the first magnetic block (53) through the controller (20), and the gate (51) is turned over and closed towards the direction of the gate mounting groove (14).
