Abstract
A floating counter-rotating vortex-eliminating device for a pump station and the pump station; the floating counter-rotating vortex-eliminating device for the pump station includes 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 surface near a water suction end of the pump station and is driven to rotate by power generated by a vortex; 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, and the plane bearing is connected to the balance weight through the elastic element to prevent inclination.
