Problems solved by technology

The most used wind power generation system is to install the wind blades on the middle shaft along its length direction perpendicular to the shaft. Such a wind generator produces a lot of wind shear noise, and the machine itself is too heavy and takes up a lot of space. ; Not suitable for ordinary families and small companies

Embodiment Construction

[0021] like figure 1 shown. The device adopts a vertical shaft type, and a vertical rotating shaft 2 is arranged in the middle. The rotating shaft 2 is connected with three blades 1 through a connecting mechanism, and the lower end of the rotating shaft 2 is connected to a generator 6 through a hollow sleeve 5 .

[0022] like figure 1 , image 3 , Figure 5 shown. Wind blade 1 is solidified and molded by polymer composite material, which is light and durable, and the weight of a single blade is less than 2 kg; its cross section is designed using modern aviation technology, and adopts NACA0009 airfoil: double-sided symmetrical convex arc shape, The chord length is 200 mm, the maximum wall thickness is 18 mm, and the length is 2400 mm. Aluminum alloy mounting joints 10 are prefabricated on the fan blades 1 respectively. The potential of the polymer composite material used in the fan blade 1 is close to that of the aluminum alloy parts used in the installation joint 10 to p...

Abstract

The breeze leaf device of the wind power system that the invention provide, includes the breeze leaf, rotate shaft, cannula, generator and adopt the perpendicular axis type, the breeze leaf presents a long form, the cross section adopt the NACA0009 wing type, breeze leaf is parallel with the shaft axis line in its length, the string perpendicularity toward the shaft axis line by the length direction, through the conjunction of horizontal beam and shafts, need not to change the windmill direction according to the direction of wind, the space take up is small, the noise is small; the Breeze leaf is solid to become the type adoption the macromolecule compound material, the shaft adoption carbon steel material to manufacture, the contact installation adopt the aluminum metal alloy material, which have good and enduring, anti-causticity, safety, applicably to the temperature changing from minus 55 deg.C to plus 70 deg.C in land, deserts, follow various bad environment of the region of etc. of sea, such as sand dust, salt fog, damp weather etc., enduring time is 20 years long.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a fan blade device of a wind power generation system. Background technique [0002] Utilizing the inexhaustible wind energy in nature to generate electricity is the most economical and feasible power supply method in windy areas, especially in remote rural areas. The wind energy conversion component is one of the key components of the wind power generation system. It converts wind energy into mechanical energy to provide the rotational torque required by the wind generator; the wind blade is the key among the keys. Whether the design of the wind blade is reasonable or not is related to The size of the wind shear noise generated by it and the amount of space it occupies. The most used wind power generation system is to install the wind blades on the middle shaft along its length direction perpendicular to the shaft. Such a wind generator produces a lot of wind shear noise, an...
