Embodiment Construction

[0031] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0032] Such as figure 1 As shown in -8, the fan impeller with movable arc-shaped blades is mainly composed of a support frame, an energy-harvesting mechanism, a deployment and recovery mechanism, and a transmission mechanism.

[0033] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 The support frame is composed of the impeller support rod 3, the eccentric rod 5, the eccentric support rod 4 and the impeller 2, and the frame can be installed on the power generation equipment. The impeller support rod 3 is concentric with the impeller 2, and its main function is to support the impeller 2; the main function of the eccentric rod 5 is to connect the connecting rod and the arc-shaped energy-harvesting blade 1, and when the wind energy is captured, the eccentric rod 5 rotates itself to expand and recover the arc-shaped trap. Can blade...

Abstract

The invention relates to a vertical shaft fan impeller with a moving arc vane. The vertical shaft fan impeller mainly comprises a supporting machine frame, an energy capturing mechanism, a stretching and recycling mechanism and a transmissions mechanism. Wind energy is converted into rotating kinetic energy of the impeller by rotating of impeller. Kinetic energy captured by the fan impeller is converted into electric energy through a power generation device. The arc energy capturing vane can fully stretch at a windward face and be fully attached to the surface of the impeller at an against-wind face, so that energy capturing efficiency is high, and great application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a vertical axis fan impeller with movable arc-shaped 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 th...
