Embodiment Construction

[0021] according to Figure 1-3 The specific structure of the present invention is described in detail. The machine is composed of a turntable platform 13 and a semi-funnel-shaped wind gathering cover 14, impeller group, central shaft support 15, impeller support frame 10, etc. arranged on the platform. The turntable platform 13 can be directly arranged on the base of a high-rise building, or can be arranged on land or sea by using pillars. The turntable platform 13 is provided with a yaw motor (not shown in the figure) and rolling elements, which can adjust the direction as the wind direction changes. The impeller group is composed of rim 5, blade 4, central shaft 1, blade connection sleeve 11 arranged on central shaft 1, cable stay cable fixed plate 3, etc., wheel rim 5, transmission support ring 8, impeller support frame 10 and blade 4 can be manufactured in sections, transported in sections, and assembled on site. The two ends of the central shaft 1 are assembled on the...

Abstract

The invention relates to a reinforced type wind-driven generator which fundamentally solves the problems of poor mechanical strength, large execution difficulty, poor practicability and the like existing in the existing large-sized wind-driven generator. The reinforced type wind-driven generator has the technical key points that both ends of a central shaft of an impeller group are assembled on acentral shaft bracket arranged on a rotating disc type platform by utilizing a bearing and a bearing seat, the root of a vane of the impeller group is fixed on a vane connecting sleeve on the centralshaft, the tip of the vane is fixed on the wheel edge of the impeller group, the middle part of the vane is fixed on a transmission support ring arranged between the central shaft and the wheel edge,both sides of the vane connecting sleeve on the central shaft are respectively provided with an inclined pull rope fixing disc fixed with an inclined pull rope, the other end of the inclined pull rope penetrates through the transmission support ring to be fixed with the wheel edge, the vane is additionally provided with a vane inclined pull rope which is connected with the inclined pull rope fixing disc, and an impeller support rack used for supporting the impeller group is fixedly installed on the rotating disc type platform. The stress of the vane of the reinforced type wind-driven generator is uniform, the vane of the reinforced type wind-driven generator can be assembled on the spot, and the reinforced type wind-driven generator has wide speed adjustable range and does not need a transmission case. The reinforced type wind-driven generator is suitable for various wind-driven power generation places.

Description

technical field [0001] The invention relates to a reinforced wind power generating device, in particular to a strong and efficient reinforced wind power generator with super large impellers, which is suitable for various wind power generating places. Background technique [0002] At present, most of the widely used large-scale wind power generation devices powered by wind energy use blades on the traditional hub or blades between the central shaft and the wheel rim. Such power generation devices have fewer blades, so for the overall impeller, the force of the wind The smaller the impeller, the lower the efficiency. Both of these two impeller structures have the disadvantages of fewer blade fulcrums and poor mechanical strength. If you want to increase the length of the blades to improve the power generation efficiency, the blades will be easily bent and damaged when encountering strong winds. , is not suitable for large-scale power generation devices, so the improvement of t...
