Embodiment Construction

[0026] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0027] This embodiment is a folding blade type vertical axis impeller based on belt transmission, including a bearing seat 1, a main shaft 2, two blade supports, four sets of gear sets 4, two belt drive sets, four blade sets and four gears. pole 9. Wherein: the main shaft 2 is installed on the bearing seat 1 through the bearing. The blade brackets are respectively fixedly installed on the upper end and the lower end of the main shaft 2, forming an upper blade bracket 10 and a lower blade bracket 3; Be fixedly connected on each bar of lower blade support 3. The four blade groups are respectively located between the upper blade support 10 and the lower blade support 3 , and are mounted on the top ends of the respective rods of the blade support 10 and the lower blade support 3 through shaft hole clearance fit. Gears are respectively installed on the rotating sha...

Abstract

The invention relates to an impeller of a foldable-blade vertical shaft based on belt drive. The impeller of the foldable-blade vertical shaft based on the belt drive comprises a bearing base, a spindle, an upper blade bracket, a lower blade bracket, four groups of gear sets, four groups of stop rods, four outer blades, four inner blades and two belt drive sets. The blades of the impeller are regularly rotated while revolved around an axis, the positions of the blades are changed so that the blades are expanded as the plate in the windward direction, the windward area is increased, and the received driving torque is improved; and the blades are folded against the wind, the headwind resistance is reduced, so the impeller of a blower has better self-startability, and higher generating efficiency.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a belt-driven vertical axis impeller with foldable 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 development of the national eco...
