Flexible universal fan blade wheel

Abstract

The invention discloses a flexible universal fan blade wheel with a compact structure, which can realize wind driving function irrelevant to the wind direction and very high wind power efficiency and ensures that running and maintenance difficulties and the workload are greatly reduced with a simple blade structure. The fan blade wheel consists of a plurality of flexible fan blades which are fixedly connected to a rotor-shaft structure, wherein each flexible fan blade consists of an upper guide fan blade section, a main windward vortex fan blade section and a lower guide fan blade section to form a flexible curved face body with a concave vortex surface and a convex surface; the fan blades are in the same tangential direction of concave vortex surface and are fixedly connected to the post side face of the rotor-shaft structure; included angles between connecting lines of the outer side edges and the inner side edges of every two fan blades in the axial direction are the same as each other; and the connecting line between the upper top point and the lower top point of each fan blade is parallel with an axial lead in the radial direction.

Description

technical field [0001] The invention relates to a wind impeller of a wind power engine. Background technique [0002] At present, the wind impellers of almost all wind turbines or other wind-powered wind impellers are driven in one direction, and their wind efficiency is guaranteed by constantly adjusting the windward or downwind direction, which makes the structure of the wind power engine system complicated, so that additional Set the wind direction follow-up control system. Like this, not only cause cost to raise, but also can make running cost raise, work efficiency reduces. Especially for high-power system wind turbines, even with an excellent wind direction follow-up control system, it is difficult to achieve high-sensitivity follow-up of rapid and frequent wind direction changes. Therefore, it is an urgent problem to be solved urgently to develop a kind of wind-driven engine which has nothing to do with the wind direction. The existing universal wind impeller is a ...

AI Technical Summary

Problems solved by technology

The existing universal wind impeller is a frame-type unidirectional vertical turbofan structure, which can realize the wind power independent of the wind direction, but its wind power efficiency is very low

The recently developed universal wind impeller is a structure with a large leaf fan and a small movable leaf fan. Although it can realize the wind power function independent of the wind direction and high wind power efficiency, its complex blade structure will make operation and maintenance difficult and difficult. Increased workload, but also high operating noise and wear
