Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as figure 1 with figure 2 with Figure 4 with Figure 5 As shown, the present invention provides a kind of power-increasing wind machine suitable for valley wind, which is mainly used in areas with valley wind such as hills. The vertical incoming flow is the valley wind, and the wind power machine of the present invention can utilize and transform these two kinds of winds simultaneously. The main output region of the horizontal incoming flow action blade 1 is outside the blade span 30%, so the quasi-vertical incoming flow action blade 13 is increased within the horizontal incoming flow action blade 1 near the blade root 30%, to capture the valley wind. Compared with the original horizontal axis wind turbine, this invention can rationally utilize and transform the horizontal inflow and vertical inflow in the valley area, increas...

Abstract

The invention discloses a power-increasing wind turbine suitable for valley wind. The power-increasing wind turbine comprises a tower drum, wherein a cabin is arranged at the top of the tower drum, the input end of the cabin is connected with a wind wheel shaft, a power generator is arranged in the cabin and used for converting mechanical energy transmitted by the wind wheel shaft into electric energy, a hub is connected to the wind wheel shaft, horizontal incoming flow action blades are connected to the hub, the plurality of horizontal incoming flow action blades are arrayed in the circumferential direction of the hub, a plurality of quasi-vertical incoming flow action blades are annularly arrayed in the rotating direction of the hub, and are bionic airfoils, the rear edges of the quasi-vertical incoming flow action blades are connected with the horizontal incoming flow action blades, the windward sides of the quasi-vertical incoming flow action blades face the blade root directions of the horizontal incoming flow action blades, the quasi-vertical incoming flow action blades on the same circle diameter are the same in structure and the wing chord lengths of all sections are the same by taking the spanwise direction of the horizontal incoming flow action blade as the reference, and the wing chord lengths of the quasi-vertical incoming flow action blades are gradually reduced in the direction from the blade tip to the blade root of the horizontal incoming flow action blade. According to the invention, the utilization rate of wind energy is increased.

Description

technical field [0001] The invention belongs to the technical field of renewable resource utilization, in particular to a power-increasing wind turbine suitable for valley wind and a power generation method. Background technique [0002] In recent years, with the intensification of energy shortages, people's awareness of environmental protection and the concept of sustainable development have also been continuously strengthened, and they have realized the importance of clean energy and renewable energy. Wind energy has attracted everyone's attention due to its advantages such as wide distribution, green and pollution-free, clean and renewable, and wind power has also developed rapidly. Wind energy resources mainly include onshore wind power and offshore wind power. Onshore wind power is mainly built in Gobi, Shanbao and other sparsely populated areas. There are two main types of wind turbines commonly used: horizontal axis wind turbines and vertical axis wind turbines. Ho...
