When river level is lower, cylindrical culvert location is higher than water level, and water flow cannot be introduced into cylindrical culvert, thus Vane wheel oar 4 will not generate rotation, and buoyancy tank 10 is not also contacted with the water surface at this time, therefore remaining each component will not generate movement.

After river level goes up, river flow velocity is accelerated, water flow, which enters in cylindrical culvert, generates thrust to vane wheel oar 4, Buoyancy tank 10 is floated by buoyancy and drives 8 upward sliding of push rod through telescopic rod 9 simultaneously, after 8 upward sliding certain distance of push rod The gasket 20 of the upper end blocks drainage hole 7, at this point, push rod 8 slide into pop-up slot 12 it is corresponding with 13 position of cylindricality card slot, because And block pin 11 under the twisting force of elastic hinge joint to the periphery of telescopic rod 9 rotation make the movable end of block pin 11 into Enter in cylindricality card slot 13, so that push rod 8 is locked at current location；With the continuous rising of water level, vane wheel oar 4 by water flow by Cumulative big thrust and generate and rotate and ramp up, and then drive water pump 5 to operate through gear pair 14 and shaft coupling 15, water pump 5 After operating, enters through the filtered water of screen element 19 through water inlet pipe 17 and pressurize in the pump housing and pump out through outlet pipe 18 to tank 6 In；Continuous promotion with water flow to vane wheel oar 4, the water in tank 6 are gradually increased, to the push rod 8 of 7 lower section of drainage hole Downward pressure is generated, but since the vertical position of push rod 8 has been locked by block pin 11, therefore drainage hole 7 will not generate leakage, protect The middle water of card tank 6 continues to increase.

When the water in tank 6 increases above spillway hole 24, extra water is discharged through spillway hole 24, so that The water quantity holding dynamic stability of tank 6 avoids rated load of the ever-increasing water beyond beam body 2 and damages beam body 2 by pressure.

In addition, under high wind state, even if river level does not go up, but due to the impetus of wind-force, vane wheel oar 4 Rotation can be generated and beam body 2 is made to increase weight, can equally play stable bridge beam action.
