Definitions
- the invention relates to the field of small energy and can be used to create wind power stations.
- a wind power installation comprising an energy converter configured to convert rotational energy, an annular pontoon rotatably rotatable about a vertical axis, rotary blades mounted on an annular pontoon rotatable around vertical axes, flexible rods connected with an annular pontoon and with the hub of the energy transducer mounted rotatably coaxially with the annular pontoon, a kinematic mechanism configured to the ability to transfer rotational energy of the ring pontoon to the receiving node of the energy converter (RF patent ⁇ "2330989, IPC F 03 D 3/06, 2008)
- the disadvantage of this solution is expressed in large hydrodynamic energy losses and low productivity, since the floating platform is made rotating.
- Also known is a wind power installation comprising blades mounted on an annular pontoon rotatably relative to a vertical axis, an energy converter configured to convert rotational energy located on a platform covered by an annular pontoon, a kinematic mechanism configured to transmit rotational energy of the annular pontoon to the receiving unit of the energy converter (RF patent Jvfe 21 18705, MKI 6 F 03 D 3/06, 1998)
- the disadvantage of the prototype is the impossibility of placing a wind power installation in the deepwater section of the shelf, since the platform in the known solution is stationary.
- the problem to which the claimed solution is directed is expressed in the removal of restrictions on the location of the wind power installation on the water surface.
- the technical result achieved in solving the problem is expressed in expanding the possible locations of wind power plants due to the free surface of the shelf of the seas with depths of more than 50 meters in the zone of the strongest and most stable winds with low turbulence, which also ensures an increase in electricity generation.
- the problem is solved in that the wind power installation containing the blades mounted on an annular pontoon made to rotate about a vertical axis, an energy converter configured to convert rotational energy, placed on a platform covered by an annular pontoon, a kinematic mechanism configured to transmit rotational energy of the annular pontoon to the receiving unit of the energy converter, characterized in that the platform is floating and equipped with positioning means, including at least six anchors placed on the bottom, predominantly pairwise connected to the platform by flexible elements so that the projection onto the horizontal plane of one flexible element is oriented radially to the axis of rotation ring pontoon, and the projection of the second flexible element is oriented tangentially, and the anchor attached to it is shifted to the side opposite to the direction of rotation of the ring pontoon relative to the fixing point of the flexible element on the platform.
- positioning means including at least six anchors placed on the bottom, predominantly pairwise connected to the platform by flexible elements so that the projection onto the horizontal plane of one flexible element is oriented radially to the axi
- the anchors are located outside the platform projection to the bottom.
- the platform contains a floating base and an overhead part equipped with an energy converter connected with a floating base completely submerged in water, sealed columns, the length of which is greater than the sum of the surface height of the platform and the depth of the zone of influence of wind waves, while the length of their cross section is greater than the width, moreover, the long axis of their cross section is oriented radially to the axis of rotation of the annular pontoon, in addition, the distance from the axis of rotation of the annular pontoon to the most remote portion of the sealed column he longer inner radius of the annular pontoon.
- the floating base of the platform is shaped into a regular polygon, with flexible elements attached to the floating base of the platform at points farthest from the axis of rotation of the ring pontoon, preferably placed at equal distances from each other. Also horizontal the dimensions of the floating base of the platform exceed the corresponding dimensions of its surface part.
- the sign "... the platform is floating and equipped with positioning means " allows you to place the wind power installation on the shelf with depths of more than 50 meters, where the use of a stationary platform is impossible or unprofitable.
- the positioning means include “at least six anchors placed on the bottom, predominantly pairwise connected to the platform by flexible elements so that the projection onto the horizontal plane of one flexible element is oriented radially to the axis of rotation of the annular pontoon”, allow to hold the floating bases from drift over the surface of the water. And the presence of flexible elements facilitates the work of the structure during waves and fluctuations in water level.
- the location of the anchors outside the limits of the projection of the platform to the bottom provides a decrease in tensile forces in the flexible elements and a decrease in the mass of the anchors, and also improves the stability of the position of the floating wind power installation.
- the signs of the third paragraph of the claims allow to reduce the influence of waves on the movement of a floating wind power installation, to increase reliability by reducing wave effects.
- the sign "... contains ... the surface part connected with the floating base, completely immersed in water, hermetic columns " provides vertical stabilization of the platform, and the signs "... while their cross-sectional length is greater than the width, moreover, the long axis of their cross section is oriented radially to the axis of rotation of the annular pontoon "can increase the mass of the attached water and, thereby, reduce the dynamic component of the tensile forces in the flexible elements and reduce the mass of the anchors.
- the sign "... the distance from the axis of rotation of the annular pontoon to the most remote portion of the pressurized column is less than the inner radius of the annular pontoon" provides rotation of the annular pontoon relative to the floating platform.
- the features of the fourth claim allow to increase the mass of the attached water and, thereby, reduce the dynamic component of the tensile forces in the flexible elements and reduce the mass of the anchors.
- a sign indicating that 11 flexible elements are attached to the floating base of the platform at points farthest from the axis of rotation of the annular pontoon, preferably placed at equal distances from each other "provides a decrease in the static component of the tensile forces in the flexible elements and a decrease in the mass of the anchors.
- the features of the fifth claim provide a reduction in tensile forces in the flexible elements and a reduction in the weight of the anchors, and also improves the stability of the position of the floating wind power installation.
- FIG. 1 shows a wind power plant in a horizontal form
- FIG. 2 is a plan view
- FIG. 3 is a horizontal section along the surface of the water.

- the wind power installation comprises a platform 1 covered by an annular pontoon 2, a kinematic mechanism 3 configured to transmit rotational energy of the annular pontoon 2 to the receiving unit 4 of the energy converter (the energy converter is not shown completely in the drawings).
- the platform 1 is made floating and equipped with positioning means, including at least six anchors 7 located on the bottom 8, mainly in pairs, associated with the platform 1 with flexible elements (cables or chains) 9 and 10 so that the projection on the horizontal plane of one flexible element 9 is oriented radially to the axis of rotation 6 of the annular pontoon 2, and the projection of the second flexible element 10 is oriented tangentially, and the anchor 7 attached to it is shifted in the direction opposite to the direction of rotation of the annular pontoon 2 relative to the fixing point 1 1 of the flexible elements 9 and 10 on the floating base 12.
- the anchors 7 are located outside the projection of the platform 1 to the bottom 8.
- the platform 1 contains um, a floating base 12 and equipped with an energy converter 4, the surface portion 13 connected to the floating base 12 completely immersed in water, sealed columns 14, the length of which is greater than the sum of the surface height of the platform 1 and the depth of the zone of action of wind waves, while the length of their cross section more than the width, and the long axis 15 of their cross section is oriented radially to the axis of rotation 6 of the annular pontoon 2, which coincides with the vertical axis of the platform 1.
- the floating base 12 of the platform 1 is given the shape of a regular polygon, p
- the flexible elements 9 and 10 are attached to the platform 1 at points 11 of the floating base 12, which are maximally distant from the axis of rotation 6 of the annular pontoon 2, preferably placed at equal distances from each other.

Attach the anchors 7 with flexible elements 9 and 10 to the floating base 12 of the platform 1 at points 1 1. Moreover, the flexible elements 9 through the anchors 7 attached to them ensure a stable position of the platform 1 in the horizontal plane, and the displaced volume of the floating base 12 and pressurized columns 14 ensures the stability of the vertical position of the platform 1.
- the wind flow acting on the blades 5 creates a torque that is transmitted through the kinematic mechanism 3 to the receiving unit 4 of the energy converter, and from the energy converter to the platform 1.
- This torque is balanced by the moment created by the horizontal components of the tensile forces in the flexible elements 10.
- the slope of the flexible elements 9 and 10 due to the remoteness of the anchors 7 from the projection of the platform 1 to the bottom 8 allows to reduce the forces and mass of the anchors 7.
- the dynamic component of the torque arising due to discontinuities wind smoothed inertia platform 1 and the associated large masses of water, which promotes non-circular shape of the floating base 12 and extended in the radial direction form columns 14 airtight.
