specific Embodiment approach 1

[0028] Specific implementation mode one: combine Figure 1 to Figure 11 To illustrate this embodiment, the vertical wind power aluminum alloy fan blade system in this embodiment includes N blades, a shaft 3, an upper flange 4 and a lower flange 8, and the vertical wind power aluminum alloy fan blade system also includes 2N 1 fixed connecting piece 5, 2N reinforced triangular plates 6 and 2N supporting pieces 7, each fan blade includes fan blade frame 1 and fan blade body 2, fan blade frame 1 and fan blade body 2 are integrally pressed and stretched by aluminum alloy Formed to form the fan blade, the longitudinal section of the fan blade body 2 is a wing streamline shape, the cross section of the fan blade body 2 is a protruding curved surface, and the upper flange 4 and the lower flange 8 are installed on the shaft from top to bottom. 3, N fan blades are in an annular array around the machine shaft 3, and the upper and lower ends of two adjacent fan blades are respectively con...

specific Embodiment approach 2

[0034] Specific implementation mode two: combination Figure 1 to Figure 3 To illustrate this embodiment, the fan blade frame 1 of this embodiment adopts a C-shaped aluminum alloy frame member, or adopts an aluminum alloy square tube or two right-angled triangular aluminum alloy tubular sections to make a rectangular frame body. Such setting reduces the weight of the fan blade and increases the strength of the fan blade. It is mainly used as a support carrier for the blade body of the fan blade. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0035] Specific implementation mode three: combination Figure 4 with Figure 5 This embodiment will be described. The number of blades in this embodiment is three. In this way, the angles of the three blades are 120 degrees apart, and the three blades complement each other to generate a balanced rotational moment, the best dynamic balance characteristics, and stable rotation. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a vertical wind power aluminium alloy fan blade system. The invention relates to a vertical wind power fan blade system. The invention aims to solve the problems that a fan blade has a heavy weight and low integral strength; the fan blade is indirectly pushed by the wind power to rotate; the wind resistance is high; and the fan blade cannot obtain a good wind power refraction guide channel when rotating to any position and angle. The first scheme adopted by the invention is that each two adjacent fan blades are connected by a supporting and pulling part; a reinforcing triangle plate is welded on a fan blade frame of each fan blade; the reinforcing triangle plates are connected with a flange plate by fixed connecting pieces; and the fan blades are formed by integrated pressing and stretching. The second scheme has the following different points from the first scheme that the fan blades are formed in a mode that the fan blade frames and fan blade bodies are welded after being manufactured in a split mode; the integrated fan blade bodies are made of carbon fibers; the third scheme has the following different points from the first scheme that the fan blades are formed in a mode that the fan blade frames and fan blade bodies are welded after being manufactured in a split mode; the insides of the fan blade bodies are made into netted skeletons by aluminium alloy belts; and the outer surfaces of the netted skeletons are coated with the carbon fiber or glass reinforced plastic. The vertical wind power aluminium alloy fan blade system is used in a vertical wind power system.

Description

technical field [0001] The invention relates to a vertical wind power fan blade system, in particular to a vertical wind power aluminum alloy fan blade system, which belongs to the technical field of wind power generation. Background technique [0002] With the development of the world's energy crisis, the use of wind kinetic energy as a new energy source for the development of modern society has become a hot spot in social development. Traditional wind turbines use huge and heavy wind blades without wind collection and protection systems, so the utilization rate of wind power is low and the volume of wind turbines is large. There are large start-up dead angles and reversing dead angles in the rotating motion; the existing airfoil blades have a small wind receiving area, low wind utilization rate, and there is a wind resistance surface on the front airfoil, and there are reversing dead angles in the rotating motion, making it difficult to increase the capacity. [0003] Acc...
