Connecting rod transmitting folding blade vertical shaft impeller

Abstract

The invention provides a connecting rod transmitting folding blade vertical shaft impeller. A main shaft is arranged on a bearing base, blade supports are respectively and fixedly arranged at the upper end and the lower end of the main shaft, four blade units are respectively located between the upper blade support and the lower blade support, rotating shafts of all blades are respectively provided with gear units, the two groups of symmetrical blades can rotate synchronously through two connecting rod transmitting mechanisms which connect the two groups of symmetrical blades, and when one group of blades gradually closes, the other group of blades gradually open. The impeller blades rotate around the shaft and can change the positions of the blades, so that the blades can be unfolded as a plane board when facing the wind, the wind facing area is increased, the received rotating torque is improved, the blades can be folded and form NACA wing type blades when facing against the wind, the wind against resistance is reduced, so that the impeller blades have good self-starting performance, the energy catching efficiency can be further improved, and the connecting rod transmitting folding blade vertical shaft impeller has a higher power generating efficiency.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a folding blade type vertical axis fan impeller driven by connecting rods. 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 nation...
