Abstract

The wind power plant includes blades mounted on an annular pontoon. The pontoon is rotatable about a vertical axis. An energy converter is situated on a platform that is encircled by the annular pontoon. A kinematic mechanism is designed so as to be capable of transmitting the rotational energy of the annular pontoon to the receiving unit of the energy converter. The floating platform is equipped with positioning means that include at least six anchors located on the bottom of a body of water. The anchors are connected to the platform by flexible members and are offset in a direction opposite to the direction of rotation of the annular pontoon relative to the point at which the flexible member is attached to the platform. The technical result is an increase in the number of places where the wind power plants can be installed and an increase in electric power generation.

Claims5

Dependent claims

A wind power plant comprising:

blades arranged on an annular pontoon made rotatable relative to a vertical axis thereof,
an energy converter for rotational energy, being arranged on a platform encircled by said annular pontoon,
a means for kinematic transfer of rotational energy of the annular pontoon to a receiving unit of the energy converter;
wherein said platform is made floatable and provided with positioning means including at least six anchors located on a bottom of a body of water, said at least six anchors being arranged in pairs and being connected to the platform by flexible members, wherein a horizontal plane projection of one flexible member is oriented radially to an annular pontoon rotation axis, and wherein a horizontal plane projection of a second flexible member is oriented tangentially to a peripheral portion of the platform, an anchor connected thereto being offset in a direction opposite to the annular pontoon rotation direction relative to the point at which the flexible member is attached to the platform.
