Embodiment Construction
[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.
[0017] Such as figure 1 , figure 2 , image 3 As shown, the present invention is a windmill blade of a vertical axis wind power generator. The windmill blade includes an upper baffle plate 3, a lower baffle plate 5, and a connecting end 7. The windmill blade is connected to the wind turbine through the connecting end 7. The windmill blade also includes a front sail board 1 and a rear sail board 4, the front sail board 1 and the rear sail board 4 are connected to a connecting angle 8, and the upper baffle plate 3 and the lower baffle plate 5 are connected to the front sail board respectively. 1. At the top and bottom positions of the rear sailboard 4, the wind blows the fron...

The invention discloses a windmill vane of a vertical axis wind driven generator. The windmill vane of the vertical axis wind driven generator comprises an upper baffle, a lower baffle and a connection end, wherein the windmill vane is connected with the wind driven generator through the connection end. The windmill vane of the vertical axis wind driven generator is characterized by further comprising a front sailboard and a rear sailboard, the front sailboard and the rear sailboard are connected to form a connection corner, the upper baffle is connected to the tops of the front sailboard and the rear sailboard, the lower baffle is connected to the bottoms of the front sailboard and the rear sailboard, and wind blows the front sailboard and the rear sailboard, so that the windmill vane rotates. The windmill vane of the vertical axis wind driven generator is simple in structure, convenient to install and free of noise, and starts at a low wind speed. The windmill vane of the vertical axis wind driven generator is higher than windmill vanes of wind driven generators of the same types in working efficiency, and widely applicable to the areas which are good in wind condition and far away from power grids or abnormal in power grid. The windmill vane of the vertical axis wind driven generator provides power for lighting, televisions and searchlights.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a windmill blade of a vertical axis wind power generator. Background technique [0002] In the 1990s, my country's independent power supply system mainly used horizontal axis wind turbines and solar photovoltaic systems to supply power, which were mainly used in special occasions such as base stations, border posts, and islands. It was mainly a logistics support system for troops. [0003] After a certain period of application, many problems were found. For example, during the typhoon, the equipment was seriously damaged, the noise was loud, which affected the normal rest of the personnel, and the interference to the communication equipment made some equipment unable to operate normally. The occurrence of these problems made the normal communication and Daily life is affected. [0004] In order to solve these problems, after a certain period of investigation and re...
