WIND-DRIVEN POWER PLANT ON WATER SURFACE Russian patent published in 2010 - IPC F03D11/00 

FIELD: power industry.

SUBSTANCE: plant contains solid foundation with bearing unit, hub and energy converter that converts hub rotation energy into electric energy, and annular platform that is flexibly connected with the hub with support on pontoon with the possibility of rotation on which there located are the blades. The platform is performed in a form of annular deck with pedestrian walkway that is located above the water surface and leaned upon the semisubmersible annular pontoon. Additionally, there provided are radial passages that are performed with the possibility of torque transmission from annular platform to the hub. The hub is equipped with subsidiary annular pedestrian path for going to the solid foundation, which is connected with the immovable pier by underwater radial passage. Annular platform is equipped with trolley that moves along the rail track. The rail track is located at the outer side of the platform periphery. Immovable pier has a support that maintains the trolley.

EFFECT: possibility to increase diametre of facility many times without increasing of whole object area with decreasing of wind and wave load on the structure that will help to use it in cultural and entertainment industry.
