Problems solved by technology

The connecting rod is made of a material as thin as a steel wire between the wind wheel and the rotating shaft. The steel wire connecting rod in this utility model only bears tension, so the structure of the whole device is not fixed, which affects the stability of the impeller when it is rotated by the wind. , which in turn affects the power generation efficiency

Embodiment Construction

[0021] As shown in the figure, the embodiment of the present invention is a straight-axis multi-blade horizontal wheeled wind power device, which includes 24 blades 2 that are uniformly sleeved on the main circle 7 in the direction, and the main circle 7 is approximately perpendicular to the wind blades 2. The angle of the wind surface passes through the blade 2, and fits with the raised part of the blade 2 at the point where the blade 2 is passed through, and is reinforced with fasteners. The purpose of setting more blades here is to improve the continuity of the device receiving wind. The four auxiliary rings 8 pass through the edge of the blade 2 at an angle approximately perpendicular to the wind-receiving surface of the blade 2, and are attached to the lifted part of the blade 2 and reinforced with fasteners. The lift-up part of the blade 2 does not necessarily lift up the part through which the blade 2 passes, and may also directly obtain a lift-like structure through sh...

Abstract

The invention discloses a straight axle multi-blade and horizontal wheel type wind power generation device, which comprises a rotating axle perpendicular to the level surface and a main ring which encloses the rotating axle and parallels to the level surface, wherein, a plurality of blades penetrate through the main ring and are fixed on the main ring, the main ring is interlocked and matched with the rotating axle, and auxiliary rings are arranged around the rotating axle, penetrate through extension ends of the wind surfaces of all the blades, and are fixedly connected and matched with all the blades. The straight axle multi-blade and horizontal wheel type wind power generation device is mainly characterized in that the wind areas of the blades are increased; the staying time of the wind on the blades is prolonged, thereby strengthening the wind pressure of the blades; the continuity of wind reception is maintained; the weights of all parts are realized to be lightest on the premise of invariant mechanical strength; the running is ensured to be stable, and the service life is prolonged.

Description

technical field [0001] The invention relates to a wind power device, in particular to a straight-axis multi-blade horizontal wheel wind power device with a vertical axis and a rim. Background technique [0002] Wind turbines are divided into horizontal-axis wind turbines and vertical-axis wind turbines. Horizontal-axis wind turbines are currently the most mature technology and occupy the mainstream market. However, due to the late start of research on vertical axis wind turbines, the research tools and methods are backward, which led to the belief that the utilization rate of wind energy of vertical wind turbines is not as good as that of horizontal generators. In fact, vertical-axis wind turbines have significant advantages over horizontal-axis wind turbines in terms of power generation efficiency and starting wind speed. With the rapid development of computer fluid dynamics, this point is increasingly recognized by people. But today's vertical-axis wind turbines are diffi...
