Problems solved by technology

[0002]At present, small and medium-sized wind turbines are used more and more widely, such as street lamps, remote areas, etc.; in the process of use, people usually think about safety, efficiency and other issues At present, the wind power generator used includes the body and the blades. With this structure, the blades may fly away from the body due to the centrifugal force during the rotation process, which may cause safety problems. In addition, most of the wind energy comes from The blade tip is lost; in order to solve these problems, some small wind turbine blades are now equipped with steel rings, which can keep the energy from being lost from the blade tip and make the blades difficult to fly out. However, due to the structure and weight of the steel ring , therefore, it is difficult to implement on a medium-sized wind turbine, and it is inconvenient to carry and install

Abstract

The invention discloses a flexible outer ring type windmill generator, which comprises a generator body and a wind wheel, wherein the wind wheel comprises a hub, vanes and flexible rings arranged on outer end parts of the vanes; the vanes are evenly arranged on the hub; connecting devices for the equant flexible rings with the same number as the vanes are arranged between the flexible rings and the vanes; reducing sheets are arranged outside the flexible rings; coatings are coated on the flexible rings; the reducing sheets are pivoted on the flexible rings; and the pivoting points divide the reducing sheets into two sections with anisomerous weights. The tips of the vanes are provided with the flexible rings, so the energy is not easy to loss from the tips of the vanes, and rotational flowis formed in the flexible rings, so as to contribute to improving the work efficiency; the flexible rings are light and can be folded, thereby being convenient in carrying and installation, and beingused on middle and small-size windmill generators; and reducing sheets and elastic elements are arranged outside the flexible rings, so the rotating speed of the vanes can be better controlled automatically.

Description

Technical field [0001] The invention involves a wind turbine, especially a wind turbine with a flexible circle on the outside of the blade. Background technique [0002] At present, the use of small and medium -sized wind turbines is becoming more and more extensive, such as street lights, remote areas, etc.; In the process of use, people usually think of safety and efficiency problems. At present, the wind generator usedDuring the spinning process, the leaves may fly away from the body during the rotation process, which may cause safety problems. In addition, most of the wind energy is lost from the tip of the leaves; in order to solve these problems, there are some small wind power generation in some small wind power generation.Steel rings are set on the blades, so that the energy can not be easily lost from the tip of the leaves, and it can make the leaves not easy to fly out. However, due to the structure and weight of the steel ring, it is difficult to achieve on the medium...
