Description

The fan structure of wind generator

The present invention relates to a wing configuration of a wind turbine.

Recently, while researching alternative energy, wind power generation has been attempted, and the construction of wind farms is being promoted in windy areas. The generator using the wind power is mainly configured to generate the electricity by rotating the pinwheel by the wind speed after directing the propeller-type pinwheel in a constant direction in which the wind blows, but in the direction of the wind. Therefore, it was insufficient to allow the pinwheel to rotate automatically, and there was a costly problem with a complicated structure to be designed to rotate 360 ° regardless of the direction of the wind.

In addition, since the pinwheel is installed to be used in a vertical state with the ground should be installed in the form of a huge structure. In addition, since the vane wings are enlarged to receive a lot of wind resistance even when the wind speed is weak, there is a problem that the structure is also enlarged by increasing the load. In addition, there is a problem of low economic feasibility in low wind areas and small power generation purposes.

The present invention is designed to solve such a problem, it is designed to achieve the best power generation efficiency regardless of the direction of the wind and wind speed, with a feature that can increase the power generation efficiency as a compact.

The pinwheel used in the present invention is configured in a form similar to an outdoor fan. The vane wing of the outdoor fan is configured to drive the generator by applying it because it can receive the wind effectively and rotate well even on a low windy day.

In the present invention, the pinwheel was always rotated at a fixed position, but the guide plate was configured to move along the direction of the wind to the outer circumferential surface of the vane. The guide plate is connected to the frame, and since the frame is equipped with a tail wing at the rear, the front side of the guide plate always faces in the windy direction. The guide plate is configured to bend the inlet to collect the wind toward the wing, so that the wind can be effectively supplied to the wing (about 1.5 times the existing wind power). In operation, the wind contacts the guide plate and is configured to hit the vane wings along the guide plate. Also, since the wind covers the wing behind the bent guide plate, the wind does not directly reach the wing. The wind resistance to try to rotate in the reverse direction is eliminated so that it can rotate smoothly.

Therefore, it can be miniaturized by a structure different from the existing generators, and since the generator can be manufactured in a small size, it can be used smoothly even in an area where a lot of wind is not blown. It is made up.

The present invention is designed to improve the power generation efficiency by improving the structure of the blade used in the wind power generator.

In the present invention, the guide plate (1) and the tail wing (4) is configured to rotate on the outer circumferential surface of the vane-shaped wing (2). The guide plate 1 is connected to the frame 5, and the tail wing 4 is configured vertically on the other side. The bearing 7 is attached to the center of the frame 5, and the frame 5 is comprised so that it may rotate. Therefore, the guide plate 1 is always located on the outer circumferential surface of the wing 2 and configured to face the windy side by the tail blades 4. Tail wing (4) part has a larger surface area than the guide plate (1) is configured to receive a lot of wind resistance, the wind always blows the guide plate (1) to face the direction of the wind.

Since the guide plate 1 is bent in a slightly open shape when viewed from the wing 2 side, the blowing wind flows along the guide plate 1 and the wings 2 along the bent portion of the guide plate 1. Inflow).

Since the inlet of the guide plate 1 is formed wide, and the part flowing into the wing 2 has the shape of being retracted, it acts like a nozzle, and the flow velocity of the wind hitting the wing 2 is Since it is about 1.5 times faster than the flow rate, it acts to amplify the strength of the wind even on windy days.

Since the bent guide plate 1 is configured to cover the wings 2 to the rear thereof, the wing 2 is not exposed to the rear of the guide plate 1 when viewed from the wind blowing direction. Therefore, when the wind blows to prevent the wind blowing to the rear of the guide plate (1) was configured to not rotate in the reverse direction. When the wind blows, the wind contacts only the front of the guide plate 1 and the wing 2 adjacent to the guide plate, so that the wing 2 opened on the side of the guide plate 91 with the wind concentrated at the entrance of the guide plate. To be driven by the wind to act on.

Each vane 2 is radially constructed about the central axis 6 and connected to the gear about the center. In the center, gears of multiple stages were installed to adjust the generator speed by gear ratio.

The vane wing 2 used in the present invention is designed to be horizontal to the ground, and has a form similar to a blower wing for discharging air in a building, so that it can easily rotate even when a weak wind blows, and has a huge structure shape. It can not be achieved, the structure can be easily configured, and can be applied to small generators.

In the present invention, since the wind is always guided to the generator's wings, it can generate power irrespective of the direction of the wind.In addition, the induction plate mounted to the front of the generator has the effect of increasing the wind speed. It can be driven. In addition, since the scale is smaller than the conventional generator, there is a feature that can be miniaturized. In particular, the simplicity of manufacture and use has the effect of increasing the economics by minimizing the failure and saving of materials.
