The utility model discloses a further set up to: the rubber ball and the energy discharging column are made of elastic materials.

Through adopting above-mentioned technical scheme, the mechanical energy of rivers transmission can be in the collision between the rubber ball and unload the swing of ability post and disperse.

The utility model discloses a further set up to: the outer layer of the pressure-bearing damping cushion is provided with an elastic ring.

Through adopting above-mentioned technical scheme, can strengthen the elastic deformation ability between pressure-bearing damping pad and the sealed lid, strengthen the effect that pressure-bearing damping pad absorbed the impact, can effectively reduce the noise.

The utility model discloses a further set up to: one or more of the flow dividing columns can be arranged on the pressure-bearing damping cushion in the center.

By adopting the technical scheme, the flow dividing columns with proper quantity can be selected according to the estimated water quantity so as to reduce the resistance loss of water flow, and the flow dividing columns are dispersed as far as possible.

The utility model has the advantages that: through setting up the energy dissipation device that falls into water, differentiate the impact force of big strand rivers into the striking between the impact of the little strand rivers of multi-beam and the rubber ball, recycle the impact that most rivers were absorbed to the pressure-bearing damping pad, final greatly reduced drainage pipe riser and violently manage the impact noise between, the device is simple, and the effect is obvious, easily installation and use.
