A scour protective device around piles with bidirectional flow power generation. A smooth water flow channel is formed by guide walls and baffle walls. A power generation device is placed at smallest section of the channel. The piles are wrapped by smooth normal distributional surfaces, and the water flow is divided to outsides of normal distributional surfaces. The guide walls at both ends are tangent to eliminate downflow of the incident flow surface and horseshoe vortex around the piles, to avoid local scour. The tidal current is introduced into the channel to accelerate, and contraction panels are further compressed to realize hydropower generation and improve the utilization rate of tidal energy. The swing door makes hydraulic turbines rotate in the same direction when the tide rises and falls, realizing reliable bidirectional hydropower generation. The system provides efficient and environmentally friendly renewable power for bridge lighting, signal lights and vessels.
A scour protective device around piles with bidirectional flow power generation, comprising a first smooth normal distributional surface guide wall, a first vertical baffle wall, a first flat-plate variable-diameter scour prevention bottom plate, a first variable-diameter semicircular cover plate, a first power generation device, a second smooth normal distributional surface guide wall, a second vertical baffle wall, a second flat-plate variable-diameter scour prevention bottom plate, a second variable-diameter semicircular cover plate and a second power generation device;
