Problems solved by technology
[0002] The wind blades of the vertical axis wind turbine must overcome the wind force to perform reverse work on its blade surface when the vertical axis blades rotate in a circular motion. Although some problems can be solved in the design of the blades, it must In this state, it is necessary to solve the reaction work of the wind force on the blades, and to solve the problem of the excessive diameter of the blade circular motion. At the same time, it is necessary to overcome the starting torque resistance of the motor, so it is very difficult to start and run.

Embodiment Construction
[0010] The present invention as figure 1 As shown, the outer rotor generator stator 10 is installed on the stator shaft 4 of the outer rotor generator, and the outer rotor generator stator is positioned at the center of the outer rotor of the outer rotor generator. The fan blades 1 and 8 are fixed on the outer rotor 2 of the outer rotor generator through the fan blade fixing part 3, and the lower bearing 5 of the shroud and the upper bearing 6 of the shroud are installed on the stator shaft. The wind direction navigation indicator 7 is installed on the shroud 9, and is fixed on the upper bearing and the lower bearing as a whole, and at the same time, the wind blade is freely moved in a 360° circle, and the fixed end 11 is fixed on the support. At the same time, a solar photovoltaic power generation device is installed on the surface of the wind deflector.
[0011] The above application case: the diameter of the shroud is 1.5m, the fan blades are 5 pieces, the breeze is 4.4m / s...

The invention belongs to the field of vertical shaft generator fan blade apparatuses, and the vertical shaft generator fan blade apparatus comprises an external rotor generator and fan blades. The vertical shaft generator fan blade apparatus is characterized in that a dome is mounted at the outside of the fan blades of a vertical shaft wind generator, wind acts on a half of fan blades at a windward side under the function of a wind direction guide sign, the other haft of fan blades are covered by the dome, the energy of the wind will not act on the fan blades in the dome in the reverse direction, the dome will always face to the windward side under the function of the wind direction guide sign, and the dome can freely move 360 degrees surrounding the fan blades.
Description
Technical field: [0001] The invention relates to the field of vertical axis wind power generation devices, in particular to the category of wind blade devices. Background technique: [0002] The wind blades of the vertical axis wind turbine must overcome the wind force to do reverse work on the blade surface when the vertical axis blades rotate in a circular motion. Although some problems can be solved in the design of the blades, it must In this state, it is necessary to solve the reaction work of the wind force on the blades, and to solve the problem of too large diameter of the blade circular motion. At the same time, it is necessary to overcome the starting torque resistance of the motor, so it is very difficult to start and run. Invention content: [0003] The purpose of the present invention is to provide a shroud-type vertical-axis generator fan blade device, which not only solves the problem of starting the vertical-axis motor in the breeze, but also has a small ci...
