Sail type generator

Abstract

The invention discloses a sail type generator, which comprises a tower body base, wherein a tower body pedestal is arranged on the tower body base, a group of swing bearing is arranged on the tower body pedestal and is internally provided with a tower body spindle, the lower end of the tower body spindle is fixedly connected with the upper end of a coupler, the lower end of the coupler is connected with a generator, the outer side of the tower body spindle is provided with a plurality of sails through sail supporting arms, and the sails drive the tower body spindle to revolve by obtaining wind power and are connected with external driving devices which control the sails to rotate. The rotation direction of the sails and the revolution direction of the tower body spindle are opposite, the sails rotate once while the tower body spindle revolves once towards the reverse direction, the leading edges of the sails always point at a wind direction, and mathematical analysis is carried out on an included angle between an equivalent plane of the sails and wind direction on the circumference on which the tower body spindle revolves according to function rules. The sail type generator disclosed by the invention has high wind-electricity conversion efficiency, and large unit output power.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a sail generator. Background technique [0002] Usually, when people talk about wind turbines, they will think of a huge propeller standing in the air, and its blades are fixed on the horizontal axis to rotate against the wind, so the wind-receiving surface of the blades is a windward circular disc-shaped plane. It is usually also called a propeller-type wind turbine, and here it is simply referred to as a propeller-type wind turbine. Its structure is as follows: figure 1 shown. [0003] In fact, there is another kind of practical wind generator at present. It is a bit like an upright egg beater, which rotates around a vertical axis during operation and receives wind from the side. It is called a Darrieus type wind generator. Its arc-shaped blade is fixed on the vertical axis and rotates around the vertical axis, so the wind-receiving surface of the blade is a c...

Problems solved by technology

[0004] However, the above two wind turbines have problems such as low wind-to-electricity conversion efficiency, poor wind coupling effect, low single-unit power, and large disturbance to the wind field.
