Description

Technical Field

[0001] The utility model relates to a field, in particular to a guide rail type vertical axis wind power generation equipment. Background Art

[0002] Vertical axis wind turbines are divided into resistance type and lift type. Resistance type has low utilization rate of wind energy and cannot be used in the design of large-scale wind power generation. Lift type blades can be driven by the lift of air, and have high utilization rate of wind energy. One of the reasons why existing vertical axis high-power wind turbines are not as popular as horizontal axis wind turbines is that the larger the power, the larger the blades. The weight of the blades makes it difficult to enlarge the cantilever beam structure. Some designers support the bottom of the blades or use the buoyancy of water as support, which can make it possible to enlarge the blades, but the blades move in a circle around the vertical axis. Although the blades are connected to the vertical axis and can be pitched at a certain angle, the blades generate negative resistance in some areas within the 360° range of rotation around the vertical axis, which is not as good as the horizontal axis blades that can generate lift during rotation. Therefore, the efficiency of existing vertical axis wind turbines is relatively low. The existing horizontal axis high-power wind turbines have a large impeller rotation diameter, so they need to set up a tower with a high installation height and high strength requirements, and need to erect motor gearboxes and other components at high altitudes. Therefore, the cost of manufacturing, transportation, installation, and maintenance is very high, and the blade molding is difficult. Utility Model Content
