Referring to Fig. 1, the vertical axis wind power generation wind collection device includes a vertical axis 10, in the four-blade blade structure, four cantilevers 7 are arranged on the sleeve of the vertical axis 10, and the intersecting angles between the four cantilevers 7 are all 90 degrees . The four cantilevers 7 are respectively connected with the four fan blades, and the fan blades include the movable blade 4 , the fixed blade 3 and the fan blade frame 1 .

A plurality of fixed blades 3 are evenly installed inside the fan blade frame 1 , and a movable blade 4 is respectively installed above the fixed blades 3 , and there is a connection between the movable blade 4 and the movable blade control rod 2 .

On the top of the blade frame 1, there is a movable blade controller casing 5, and a right-angle impeller 6 is arranged inside the movable blade controller casing 5, and the right-angle impeller 6 includes several right-angle impeller blades 9. In addition, several air guide vanes 8 are arranged inside the movable vane controller casing 5 . The wind guide vanes 8 are arranged vertically, the right-angle impeller blades 9 are evenly distributed from the horizontal plane to the vertical plane, and the outer edges of the right-angle impeller vanes 9 and the wind guide vanes 8 are perpendicular to each other.

Fig. 2 is a top view of the utility model, and this figure is a four-blade blade structure. The four cantilevers 7 are respectively connected with the four fan blades, above the four fan blades is the movable blade controller housing 5, and the movable blade controller housing 5 is provided with a right-angle impeller 6, and the movable blade controller housing 5 can be seen from the right side The inside is also provided with guide vanes 8 and right-angle impeller blades 9. A movable blade control rod 2 is arranged on the four fan blades, and the movable blade control rod 2 is connected with the right-angle impeller 6 and is controlled by the right-angle impeller 6 .

Referring to FIG. 3 , there is a movable blade controller 11 above the fan blades of the vertical axis wind turbine, and the movable blade controller 11 includes a movable blade controller housing 5 , a right-angle impeller 6 , and a wind deflector 8 . There is a vertical shaft 10 in the middle of the vertical axis wind power generating set, the bottom of the vertical shaft 10 is connected to the gearbox 12 , the gearbox 12 is connected to the generator 13 , and the vertical axis wind power generating set also includes a bracket 14 .

Fig. 4 is A_A sectional view of the utility model. The structure of the movable vane controller 11 is shown above, including the movable vane controller housing 5 , right-angle impeller 6 , wind guide vane 8 and right-angle impeller blade 9 . Shown below is the fan blade structure, including the movable blade control rod 2 , the fixed blade 3 and the movable blade 4 . As can be seen from the figure, the movable vane control rod 2 and the movable vane 4 are hingedly connected by a lever. Meanwhile, the movable blade 4 is arranged above the fixed blade 3 .

FIG. 5 is a schematic structural diagram of the movable vane controller 11 . The movable vane controller 11 also includes a wind collecting cover 15 . The right-angle impeller 6 and the movable blade control rod 2 are hingedly connected by a lever. When the wind enters the inside of the right-angle impeller 6, a rotational moment will be generated, which will drive the movable blade control rod 2 to move downward, as shown in Figure 4 After the movable blade control rod 2 moves downward, it will drive the movable blade 4 to close the fan surface of the fan blade.

Referring to Fig. 6, the air guide vane 8 is arc-shaped, and the air guide vane 8 can guide the wind blowing from a certain angle direction to the front of the right-angle impeller blade 9, so that the right-angle impeller 6 can run better.

The working principle of the utility model is that when the wind blows to the slope of a certain fan blade, the movable blade controller 11 will act to drive the movable blade control rod 2, so that the movable blade 4 in the fan blade will be lifted up, which is the same as the fixed blade above. 3 form a closed fan surface to block the wind, generate the thrust of the wind on the fan blades, and form the rotational moment of the entire structure. The rotational moment is transmitted to the vertical shaft 10 through the cantilever 7, and then transmitted to the gearbox 12 through the vertical shaft 10, and then to the generator 13, thereby driving the generator 13 to rotate and generate electricity.

When another fan blade rotates to its slope and begins to accept the wind force and reaches a certain angle, the wind guide vane 8 in the movable blade controller 11 will guide the wind with a certain angle as the front blowing force to the right-angle impeller 6, and due to the collection of wind When the angle of the angle increases to reach enough blowing force, this other fan blade also produces the same as last fan blade and stops wind from the action of fan blade and forms the thrust of wind to it. When it rotates to a certain angle, the movable blade controller 11, due to the influence of the wind deflector 8, the power to promote the upward movement of the movable blade 4 disappears at first, but because the thrust of the wind to the movable blade 4 still exists and continues to keep it rising to a certain level. angle. When the angle of the wind to the fan blade plane is not enough to produce the thrust that prevents the movable blade 4 from falling on the fixed blade 3 below it, the gravity of the movable blade 4, the reset gravity of the movable blade controller 11 and the movable blade control lever Under the resultant force of the gravity of 2, the movable blade 4 falls to the fixed blade 3 below it, so that the air passes through the blade smoothly, thereby reducing the rotational resistance of the blower fan to the greatest extent.

The utility model sets movable blades 4 on the wind collection device, and the movable blades 4 move to form a closed fan surface during work, and use the largest wind resistance area to generate rotational torque, while the movable blades 4 are opened in the non-working position to allow the air to pass through with the largest area. Minimizes air resistance to rotational torque, thus producing maximum rotational torque. By setting the movable blade controller 11, the wind collection device can form a closed fan in advance, increasing the wind collection angle. The principle of the utility model is to close the maximum area of the fan blades when the wind collecting work is started, so as to generate the maximum wind-blocking area, which may hinder the flow velocity of the wind to the greatest extent, and greatly improve the utilization efficiency of wind energy.
