Highly effective power generation windmill group

Abstract

The invention relates to a power generation windmill group, belonging to the technical field of generating sets. The power generation windmill group comprises a main shaft, vanes, vane sleeve shafts, a supervoltage sensor, a connector for a phase converter at the root parts of the vanes, a power transmission gear, a fan cover, vane groups with diverse directions. The power generation windmill group is characterized in that the diameters of the vanes of the windmill can be designed to be from large to small, or be equal to one another, or be small to large; a plurality of vane groups are connected in series on the same shaft, and the forced directions of the vanes are mutually reversed. When wind passes through the first vane group, and the second vane group is blown to rotate by the rest energy to do work, and so on. When the wind force exceeds a preset insurance value, the supervoltage sensor automatically causes the vanes to rotate, surfaces contacting the wind become smaller and smaller until being smallest, and the direction is not changed, thereby playing the function of protecting equipment and increasing the power generation efficiency.

Description

Technical field: [0001] The invention relates to a wind turbine group for generating electricity. Background technique: [0002] Traditional windmills are installed on the horizontal shaft at the upper end of a high pole or elevated frame. The blades are generally similar to the blade shape of a fan, and most of them are narrow and long, and can only work independently. Therefore, the output power of power generation is relatively small, and the utilization rate of wind power per unit area Low, encounter typhoons and storms without protection measures and other ills. Invention content: [0003] The technical problem to be solved by the present invention is to provide a multi-group windmill with variable blades connected by rings at the ends. Just like the multi-layer impeller group of a thermal power turbine, it can make full use of the residual wind energy multiple times, and can automatically change the angle of the blades in the event of a typhoon or storm to ensure th...
