Problems solved by technology

However, as the power increases, the method of using a vertical shaft to carry the blade or using a roller to support a single blade cannot withstand the increased material weight due to the continued increase in power, nor can it meet the increased structural strength of the cantilever structure. Require
[0004] To sum up, under the condition of ensuring a sufficient wind receiving area, how to ensure that the vertical axis wind turbine can withstand a larger wind load structure with the increase of power, so far there is no good solution

Abstract

A squirrel-cage vertical shaft wind generating set comprises a support frame (1), a wheel (2), a blade plate (3), a squirrel cage (4), a squirrel cage shaft (5), a locating bearing seat (6), a generator (7), a small coupler (8), a gear case (9) and a big coupler (10). In the support frame (1), the squirrel cage (4) is integrally arranged in the support surface of the support frame and rotates under the action of wind load; and the squirrel cage shaft (5) drives the generator (7) to rotate and output electrical energy by means of the gear case (9).

Description

technical field [0001] The invention relates to a wind power generating set, in particular to a large, high-power, low-cost squirrel-cage vertical axis wind power generating set. Background technique [0002] Wind turbines are divided into two categories: horizontal axis and vertical axis. At present, large-scale wind power equipment is mainly based on the horizontal axis. However, when large horizontal axis wind turbines are developed to a power of 1MW or more, they are already approaching the limits of existing material strength, design and manufacturing. For example, the installation height of a large horizontal axis wind turbine exceeds 100 meters, and the cost of equipment manufacturing, engineering construction and maintenance is huge. It requires expensive precision dynamic balancing blades, precise yaw system, huge force variable pitch speed control system, and a tower that consumes a lot of materials. Due to the high installation height, the wind resistance of th...
