Problems solved by technology

Here's why existing wind turbines are inefficient
In addition, the existing wind turbines are supported by a single column, which is a cantilever structure, and the strength will be very low
Restricted by the strength conditions, the blades cannot be made very wide, nor can they be designed into other heavy shapes, and it is even more impossible to withstand the huge axial wind force generated by greatly increasing the wind receiving area.

Embodiment Construction

[0014] Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. as attached figure 1 , 2 Shown, weld the metal wheel frame (2) of a circular frame structure with steel pipe. as attached Figure 5 As shown, the steel pipe (8) is penetrated and embedded in the sail board along the edge of the sail board (3), and the two ends are welded with end thin rods (9) to block the two ends of the steel pipe to prevent rainwater from flowing into the steel pipe inner wall. On the other hand, the diameter of the thin rod (9) at the end is smaller than that of the steel pipe (8) to form a shoulder, thereby preventing the steel pipe from loosening and stringing in the sailboard. The steel pipe (8) runs through the entire sailboard (3), and plays the role of skeleton and reinforcement for the sailboard. The two ends (9) of the steel pipe (8) stretch out and are fixed on the metal wheel frame (2). as attached f...

Abstract

A double-column sailboard type wind turbine relates to the field of wind power generation, overcomes the problem that the existing wind driven generator is low in efficiency, and dramatically raises generator efficiency. The double-column sailboard type wind turbine is technically characterized in that a steel pipe is welded into a circular or equilateral polygon metal wheel rim (2) of frame structure to be a framework of the wind turbine; a plurality of sailboards (3) are fixed on the metal wheel rim (2) to form a huge wind turbine; and two ends of a turbine central shaft extend out and are supported by vertical columns (1) built by reinforced concrete. Compared with the existing three-blade wind-driven generator, the wind turbine is enlarged by tens of times in windage area, with the windage surface far from the center and good wind effect. The utilization rate of wind energy and generator power can be dramatically improved. The wind turbine can drive a generator group consisting of a plurality of generating units.

Description

technical field [0001] The present invention relates to wind power generators, and in particular to wind power generator turbines. technical background [0002] In the existing wind generators, wind energy is captured by several blades (usually three blades), and the wind-receiving surface of the blades is very small, so the acquisition of wind energy is extremely limited, and most of the wind energy is not utilized. And restricted by weight and strength, the root of the blade is relatively wide and thick, but the tip is very narrow. According to the principle of mechanics, the closer the force is to the center, the smaller the torque will be, and the farther the force is from the center, the greater the force distance will be. Therefore, the most effective place to capture wind energy should be near the tip of the blade away from the center, and increasing the width of the root of the blade is ineffective. This is the reason for the inefficiency of existing wind turbines....
