Embodiment Construction

[0030] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0031] Such as figure 1 As shown, a vertical axis wind impeller mainly consists of a main shaft 4, an upper bracket 2, a lower bracket 8, a first baffle 3, a second baffle 5, a third baffle 9, a fourth baffle 11, a first blade 1. Composed of the second blade 6, the third blade 7, the fourth blade 12 and the movable base 10.

[0032] Such as figure 2 As shown, the main shaft 4 is cylindrical, and there is a boss at the top and bottom of the main shaft, which are respectively the first boss 13 and the second boss 14 . The main shaft 4 is installed on the movable base 10 .

[0033] Both the first boss 13 and the second boss 14 are cylindrical, and both have the same diameter. Both the axis of the first boss 13 and the axis of the second boss 14 coincide with the axis of the main shaft 4 . The first boss 13 is located at the top of the main shaft 4 , and the se...

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a vertical axis wind power generation impeller with movable blades. Background technique [0002] Energy is the driving force and guarantee for the development and progress of human society. In recent years, with the rapid development of the global economy, conventional energy sources such as coal, oil, and natural gas have been consumed rapidly and in large quantities, which not only confronts human beings with the pressure of depletion of resources, but also is threatened by the continuous deterioration of the environment. Energy and environmental protection have become urgent problems that need to be solved urgently for human survival and development. As a clean and environmentally friendly new energy source, wind power neither consumes limited coal resources nor valuable underground wind resources, and is more conducive to the sustainable developmen...
