Floating counter-rotating vortex-eliminating device for pump station, and pump station

A floating counter-rotating vortex-eliminating device for a pump station, comprising:

• a floating driving disc, a counter-rotating gear box, a reverse-rotating disc, a plane bearing, an elastic element, and a balance weight;
• the floating driving disc floats on a liquid water surface near a water suction end of the pump station and is driven to rotate by power generated by a vortex of the water surface;
• the floating driving disc is connected to the reverse-rotating disc through the counter-rotating gear box, such that the reverse-rotating disc and the floating driving disc have different rotating directions;
• the plane bearing is mounted at a bottom of the reverse-rotating disc, the plane bearing is connected to the balance weight through the elastic element to prevent inclination;
• the floating driving disc comprises a plurality of driving blades, a buoyancy disc, a driving disc hub, a driving shaft, and a driving bevel gear;
• the plurality of driving blades are uniformly distributed between the buoyancy disc and the driving disc hub, an upper end of the driving shaft is connected to the driving disc hub, a lower end of the driving shaft is connected to the driving bevel gear, the power generated by the vortex is applied to the plurality of driving blades, such that the floating driving disc and the vortex have a same rotating direction.
