Problems solved by technology

However, due to the small wind receiving area and weak wind suction capacity of the existing wind turbine blades, the effective utilization of wind energy cannot be realized.
In addition, the conventional material used in existing wind power blades is glass fiber reinforced resin, which is an inorganic polymer material. The blades of this material also determine their own weak structural strength. In order to avoid wind damage, wind power blades are generally It is designed in a structural form with successively decreasing widths. This structural form cannot absorb wind well and cannot realize the maximum utilization of wind energy.

Embodiment 1

[0023] see figure 1 , 2 , a wind power blade, including a blade body 1, the side of the tail end of the blade body 1 is a planar structure, which increases the wind receiving area of ​​the tail end, increases the resistance of the tail end, and reduces the speed of the wind power blade, but due to the wind suction The capacity is stronger, and the overall power generation efficiency will not be reduced. On the contrary, the noise reduction effect is achieved by reducing the speed of the wind turbine blades.

[0024] The wind power blade of this embodiment is designed as a plane structure on the side of the tail end of the blade body 1 to ensure that the end of the wind power blade has a high structural strength, is not easily damaged by wind force, and has a long service life.

[0025] In this embodiment, after the blade body 1 is installed, the projected side edges along the direction of the rotation axis are all linear structures. The blade body 1 includes a connecting por...

Embodiment 2

[0031] see image 3 The difference between this embodiment and Embodiment 1 is that the tail end side of the blade body 1 is a curved surface structure, and the blade body 1 is made of aluminum alloy, which is lighter in weight, higher in strength, and higher in wind energy conversion efficiency. , the rest of the structure is the same as in Example 1.

Abstract

The invention discloses a wind power blade which comprises a blade body, the side face of the tail end of the blade body is of a plane structure or a curved surface structure, and the invention further discloses a wind power system comprising the wind power blade. According to the wind power blade, wind energy can be utilized to the maximum extent, and the wind power blade is high in strength, not prone to being damaged by wind power and long in service life.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power blade and an application thereof. Background technique [0002] Wind turbine blades are the key components of wind turbines. The wind turbine blades are driven by the wind to rotate the hub, and the hub transmits the torque to the main shaft, and finally converts wind energy into electrical energy through the generator. With its clean and environment-friendly features, wind power has become an important part of new energy and has drawn more and more attention from people. [0003] In order to reduce the resistance at the tail of the existing wind power blades, the tail end of the wind power blades is generally set in a pointed structure, that is, a point-like or linear structure. Small, the resistance is also relatively small. However, due to the small wind-receiving area and weak wind suction capacity of the existing wind power blades, the effective utilizatio...
