The invention relates to the field of wind power, in particular to wind turbines, and can be used for obtaining mechanical and electrical energy. The technical result consists in increasing the efficiency of using wind energy by a wind turbine with the help of wind control screens. The windmill contains a rotating wind turbine with a vertical axis of rotation and external wind turbines along the circumference of the vertically free winding screens around each vertical axis, where each wind control screen is provided with rollers and mounted in a frame on guides located along its upper and lower edges, Direction. Moreover, the wind control screens in the frame consist of several parts and are made sliding with the possibility of forced change in their width depending on the natural wind speed. The frame together with the wind control screens is hinged on a vertical axis with the possibility of freely rotating it around a vertical axis in a given sector. The location of the frame fastening on the vertical axis is designed so that when the parts of the wind control panels are positioned in the extreme position in the frame, it is able to freely rotate about the vertical axis under the influence of the air flow.
DESCRIPTION OF THE INVENTION
The invention relates to the field of wind power, in particular to wind turbines, and can be used for obtaining mechanical and electrical energy.
A wind turbine is known, which contains a rotating wind turbine with a vertical axis of rotation and wind turbines located around the circumference of the vertical winding screens around the vertical axes.
A disadvantage of this device is that the wind control screens can not control the speed of airflow through the wind turbine when the wind speed changes and prevent free airflow from the volume of the windmill.
The aim of the invention is to increase the efficiency of using wind energy by a wind turbine using wind-guided screens.
This goal is achieved by the fact that in a known windmill containing a rotating wind turbine with a vertical axis of rotation and wind turbines located around the circumference of the free winding screens around each vertical axis, where each wind control screen is located in the free turn sector and the extreme positions are given by a straight line passing through the rotation axis A wind turbine and a wind control screen and a tangent to the circle formed by the rotation of the outermost point of the movable plane of the blade passing through the axis of rotation of the wind control screen, according to the invention, each wind control screen is provided with rollers and mounted in a frame on guides located along its upper and lower faces, Moving the screens along them in the horizontal direction. Vetronapravlyayuschie screens in the frame consist of several parts and are made sliding with the possibility of a forced change in their width, depending on the natural wind speed.
The frame together with the wind control screens is hinged on a vertical axis with the possibility of freely rotating it around a vertical axis in a given sector.
The location of the frame fastening on the vertical axis is designed so that when the parts of the wind control panels are positioned in the extreme position in the frame, it is able to freely rotate about the vertical axis under the influence of the air flow.

FIG. 1 is a schematic diagram of a windmill in plan with wind control screens and a wind turbine that are adjustable in width and freely movable in the frame. The dashed line shows the position of frames with width-adjustable wind control screens when the direction of the wind changes by 90 degrees and the position of the screens in the frame changes. FIG. 2 shows a diagram of the arrangement of frames with wind control screens for hurricane air flows with retracted stoppers. FIG. FIG. 3 shows portions of a wind screen that are freely movable on the rollers along the guide rails. |
The windmill includes a wind turbine 1 with a vertical axis of rotation 2, blades 3, wind control screens 4, provided with rollers 5 and mounted on rails 6 in frame 7. The frame can freely rotate about a vertical axis 8 in a predetermined sector defined by stoppers 9.
Wind turbine works as follows. When the wind appears, the air flow 10 is directed to the wind turbine 1 through the wind-guiding screens 4 which are made sliding relative to each other and can be forced to increase or decrease in width when the wind speed changes. In this way, the speed of the airflow passing through the volume of the wind turbine 1 is maintained. When the airflow 10 leaves the volume of the wind turbine, which slides along the surface of the wind control panel 4 located on the windward side of the windmill, it moves it on the rollers 5 along the guides 6 to the extreme position of the frame 7 This causes the frame, under the influence of wind, to turn around the vertical axis 8 and align with the movement of the air flow, which will facilitate free airflow from the volume of the windmill. In the case of hurricane air currents 11, the stoppers 9 limiting the sector of rotation of the frame are retracted and the frames 7 together with the wind control screens 4 begin to work in the weathervane mode, easing the pressure on the wind control screens and the supporting structure, preventing their destruction.
The proposed design of wind control screens will allow to regulate the speed of air flow in the volume of the wind turbine and will not allow the destruction of the supporting structure and wind control screens during the action of hurricane air currents.
