AI Technical Summary

Technical Problem

The existing wind power generation devices have low wind conversion rates, high blade assembly and maintenance costs, and are prone to damage under strong wind conditions, which increases maintenance costs.

Method used

The rim support frame and the roulette are used to form a blade placement area, in which the blades are densely distributed and arranged in a twisted structure, the first end is connected to the roulette, and the second end can be detached and connected to the rim support frame, and the blades are quickly disassembled and stored through a cable and a winding device.

Benefits of technology

It improves the wind catchment efficiency and wind conversion rate of wind power generation devices, enhances the structural strength of the blades, reduces maintenance costs, and protects the blades from damage under strong wind conditions.

Abstract

According to the wind power generation device, a wheel flange supporting frame and a wheel disc are matched to form a blade placement area, a plurality of blades are densely distributed in the blade placement area, projection lines of the adjacent side edges of every two adjacent blades are located on the same straight line, the blades are matched with one another and closely distributed, the wind catching area of the blades is increased, and meanwhile the wind catching effect is improved. The first ends of the blades are connected with the wheel disc, the second ends of the blades are detachably connected with the wheel flange supporting frame, and projection lines of the first ends and the second ends are distributed in an included angle mode, so that the blades can better adapt to changes of wind flow in the twisting and rotating process, high lift force and low resistance are kept, the wind catching efficiency is improved, and therefore the wind power conversion efficiency is improved; the structural strength of the blades can be enhanced, deformation and vibration caused by wind loads can be resisted, the stability and safety of the whole wind power generation device are improved, when the wind loads are large, the blades can be detached from the rim supporting frame, the blades are prevented from being damaged, and the maintenance cost of the wind power generation device is reduced.
