Abstract

A wind power collection device, a gas storage device, and a power generation system, where the wind power collection device includes an impeller, an outer side wall of the impeller is composed of four mutually spliced flow guide surfaces, radial cross sections of the four mutually spliced flow guide surfaces correspond to four mutually spliced flow guide curves, the flow guide surfaces are formed by rotating and stretching the flow guide curves around an axis line of the impeller in an axial direction; and the flow guide curves include a segment of convex first logarithmic spiral line and a segment of concave second logarithmic spiral line, and the first logarithmic spiral line and the second logarithmic spiral line of the flow guide curves are smoothly and transitionally connected at one side close to the axis line.
