Abstract
The utility model relates to a fan blade structure for vertical-axis wind power generation equipment and belongs to the technical field of wind power generation equipment. The fan blade structure adopts the following technical scheme: the fan blade structure comprises fan blades (1), supporting rods (2) and a central shaft (4), wherein the fan blades are connected with the central shaft through the supporting rods; the fan blade structure is characterized in that support fan blades are arranged on the supporting rods (2); more than two supporting rods are transversely arranged between fan blades and the central shaft in parallel; and support fan blades are arranged between the upper supporting rod and the lower supporting rod. The fan blade structure for the vertical-axis wind power generation equipment has the positive effects that wind-driven capacity of the fan blade structure is improved due to the adoption of the dual-layer fan blades, the fan blade structure can be started even with breeze, and meanwhile, the strength of the fan blade structure is improved.
Description
Technical field
The utility model relates to a kind of blade structure of wind power generating set with vertical shaft, belongs to technical field of wind power generating equipment.
Background technique
At present; Wind-power electricity generation has obtained extensive use; Vertical axis aerogenerator has characteristics such as operate steadily, generating efficiency is high, the generating curve is full; Mainly be divided into flabellum part and master section, vertical axis aerogenerator catch Safety performance and the generating efficiency that wind energy power, structural strength etc. affect vertical axis aerogenerator.At present, there is following problem in the vertical axis aerogenerator blade structure of background technique: structural strength is perfect inadequately, catch a little less than the wind energy power.
The model utility content
The purpose of the utility model provides a kind of blade structure of wind power generating set with vertical shaft, improves intensity, strengthens the wind energy power of catching, and solves the problems referred to above that background technique exists.
The technological scheme of the utility model is:
A kind of blade structure of wind power generating set with vertical shaft comprises flabellum, pole, central shaft, and flabellum is connected with central shaft through pole, and its specialization is that pole is provided with the support flabellum.
Said pole quantity is more than two, between the flabellum that is connected, central shaft laterally, be arranged in parallel, the support flabellum is arranged on up and down between two poles.
Said support flabellum sectional shape is arbitrarily, and preferable sectional shape is a crescent shape; The two ends of support flabellum are connected through bolt with lower fulcrum bar with upper rack posts respectively.
Flabellum is provided with support, and an end of said pole is plugged on the support of flabellum, connects through bolt, and the other end of pole is connected with the central shaft flange through bolt.
Said flabellum has four, the even branch of ring central shaft; The support flabellum also is provided with four, is an angle of 90 degrees with flabellum.
The two ends of flabellum are the streamline shape of wing blade.
The good effect of the utility model is: owing to adopt double-deck flabellum, thus having improved band wind energy power, under the situation of gentle breeze, can start, improved intensity simultaneously.
