When people need use drainage equipment, can use this kind of municipal administration with anti-storm urgent drainage equipment, at first people can install this equipment at the gate, and this equipment downside is installed on ground and is connected with the sewer, when rainstorm, the indoor rainwater can flow in collecting vessel 3 along installation grillage 2, thereby flow to rivers acceleration mechanism 4, when the water level in rivers acceleration mechanism 4 part constantly rises, make rivers acceleration mechanism 4 operate, thereby make drainage mechanism 5 operation and mechanism 6 that intakes operate, can open the water inlet of bottom plate 1, make subaerial hydroenergy flow inside bottom plate 1, thereby flow to the sewer, when rivers acceleration mechanism 4 water level constantly descends, make drainage mechanism 5 stop the operation and mechanism 6 that intakes reversely operate, can close the water inlet of bottom plate 1.

Rainwater in the collecting vessel 3 can flow in the stock solution bucket 41, when the water level of stock solution bucket 41 constantly rises, rainwater can flow in first catheter 44, thereby make turbine 45 rotate with higher speed, the rainwater is arranged inside bottom plate 1 through drainage mechanism 5 again, rethread bottom plate 1 is arranged in the sewer, realize the effect that rivers are with higher speed, when the water level of stock solution bucket 41 constantly descends, because the impact force that loses the rainwater makes turbine 45 stall with higher speed, the rainwater also can instil into in outlet pipe 42 through drip piece 43, rethread outlet pipe 42 flows on bottom plate 1.

When the water level of the liquid storage barrel 41 is continuously increased, the rainwater flows into the second liquid guide pipe 55 from the first liquid guide pipe 44, since the one-way rotation turbine 56 is rotated clockwise by the impact of the rainwater, and thus the second rotating shaft 54 is rotated clockwise, the rainwater can flow into the outlet pipe 42 through the second liquid guiding pipe 55, the clockwise rotation of the second rotating shaft 54 causes both the first transmission belt 53 and the third transmission belt 58 to transmit clockwise, thereby causing the first rotating shaft 52 to rotate clockwise, thereby driving the second transmission belt 57 to transmit, and then driving the waterwheel 51 to rotate clockwise, so that the rainwater discharged into the bottom plate 1 can be rapidly discharged into the sewer, realizing the effect of water discharge, when the water level of the reservoir 41 is continuously decreased, rainwater does not flow into the second liquid guide pipe 55 from the first liquid guide pipe 44, and the unidirectional rotation turbine 56 stops rotating due to the loss of the impact force of the rainwater.

When the water level in the stock solution bucket 41 constantly rises, make buoyancy plate 65 upward movement, thereby first slide bar 64 upward movement, first spring 66 is compressed, thereby drive link 63 upward movement, and then drive apron 61 upward movement, direction telescopic link 62 is extended, apron 61 upward movement can be opened the water inlet of bottom plate 1, make subaerial rainwater also can flow to on the bottom plate 1, realize the effect of intaking, when the water level in the stock solution bucket 41 constantly descends, because first spring 66 resets and drives buoyancy plate 65 downward movement, thereby drive first slide bar 64 downward movement, and then drive link 63 and the equal downstream of apron 61, make direction telescopic link 62 reset, apron 61 downward movement can be closed the water inlet of bottom plate 1.

When the buoyancy plate 65 moves upwards, the buoyancy plate 65 drives the second sliding rod 71 to move upwards, when the top end of the second spring 73 touches the water dripping block 43, the second spring 73 is compressed to drive the flow limiting block 72 to move upwards, when the flow limiting block 72 moves upwards and contacts with the limiting block 74, a water outlet at the upper part of the water outlet pipe 42 can be blocked, rainwater cannot flow out from the upper part of the water outlet pipe 42, so that the water flow flowing to the first liquid guide pipe 44 is increased, when the buoyancy plate 65 moves downwards, the buoyancy plate 65 drives the second sliding rod 71 to move downwards, the second spring 73 is reset, and the second spring 73 plays a buffering role to drive the flow limiting block 72 to move downwards, so that the flow limiting block 72 is not in contact with the limiting block 74.

When the cover plate 61 moves upwards, the cover plate 61 drives the connecting block 85 to move upwards so as to drive the wedge block 89 to move upwards, when the wedge block 89 moves upwards to contact with the top block 88, the top block 88 moves inwards so as to drive the fixture block 86 to move inwards, the third spring 87 is stretched so as to prevent the fixture block 86 from contacting with the swing rod 83, the swing rod 83 swings outwards under the reset action of the torsion spring 82, so that the warning flag on the swing rod 83 also moves outwards, the rotating rod 81 rotates outwards so as to facilitate a pedestrian to watch the warning flag, so as to play a warning role, when the warning flag is not needed to be used, the swing rod 83 can be pushed to swing inwards, so as to drive the rotating rod 81 to move inwards, so that the warning flag moves inwards, the torsion spring 82 deforms in a twisting manner, when the cover plate 61 moves downwards, the cover plate 61 drives the connecting block 85 to move downwards, so as to drive the wedge block 89 to move downwards, so that the wedge block 89 does not contact with the top block 88, under the action of the reset of the third spring 87, the top block 88 is moved outwards, so that the latch 86 is moved outwards, and the swing rod 83 is clamped.

Rainwater can flow to the screen cloth 93 through bottom plate 1 in, the sewer is flowed to rethread screen cloth 93, the great solid matter of rainwater is stayed in screen cloth 93, realize filterable effect, when people need clear up the impurity in the screen cloth 93, can manually take out cardboard 94, thereby make the screen cloth 93 take out, people can clear up the impurity in the screen cloth 93, the back of clearing up, can put the cardboard 94 back to the normal position, thereby make the screen cloth 93 put back to the normal position.

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.
