Embodiment 1

[0025] Such as figure 1 As shown, a wind power generation device provided by the present invention includes a generator 1, a vertical pole 2, a connecting rod 3 and blades 4, a mounting plate 5 is installed above the vertical pole 2, and a mounting plate 5 is installed above the mounting plate 5 Generator 1, a plurality of connecting rods 3 are installed on the top of the generator 1, blades 4 are installed on the ends of the connecting rods 3, and the mounting plate 5 can facilitate the integrated installation of the generator 1, and at the same time facilitate replacement and maintenance. Ribs 14 can be connected between the mounting plate 5 and the pole 2 to improve stability.

[0026] Among them, such as figure 2 As shown, the generator 1 includes a rotor 6, a stator 7, a bearing 8 and a rotating shaft 9, the stator 7 is fixed on the mounting plate 5 by a fastener 10, and the fastener 10 can be a fastening bolt or other fastening components, the middle part of the stato...

Embodiment 2

[0029] Such as image 3 As shown, the blade 4 is a hollow blade, and the outer surface of the blade 4 is arc-shaped, and a spacer 13 is arranged inside the blade 4, and the outer surface of the spacer 13 is arc-shaped, and the spacer 13 The upper and lower intervals are arranged, and the hollow blades are supported by pads 13 to ensure the stability of the hollow blades.

[0030] Wherein, the spacer 13 is provided with a bolt connection hole, and the spacer 13 is two pieces, arranged at intervals up and down, so as to ensure that the blade will not be twisted.

[0031] The shape of the blade in the invention adopts an aircraft airfoil with good aerodynamic performance, and the internal cavity of the blade adopts a box structure, which improves the strength and stability of the blade and can maximize the use of the lift characteristics of the airfoil.

Embodiment 3

[0033] Such as image 3 As shown, the connecting rod 3 can be an elastic telescopic rod. When it is first started, the speed is low, the centrifugal force is small, the telescopic rod is in a contracted state, the diameter of the blade track circle is small, and the solidity of the blade is large. The starting torque is larger at lower wind speeds, so that the fan can self-start at lower wind speeds; after starting, the centrifugal force increases, the telescopic rod extends, and the diameter of the blade track circle increases, thereby reducing the solidity of the blades, making the fan The tip speed ratio is increased, the aerodynamic efficiency of the fan is improved, and the blade diameter is increased to increase the windward area, increase the converted wind energy, and greatly increase the power generation; when encountering strong winds, due to the small blade solidity, the aerodynamic efficiency of the fan The stall performance is good. When the speed is controlled at...

Abstract

The invention discloses a wind power generating device. The wind power generating device comprises a generator, a vertical rod, connecting rods and blades. The upper portion of the vertical rod is provided with a mounting disc. The upper portion of the mounting disc is provided with the generator. The upper portion of the generator is provided with the connecting rods. The end parts of the connecting rods are provided with the blades. By means of the wind power generating device, the technical problems that a wind power generating device is low in wind catching efficiency, poor in wind resistance and inconvenient in maintenance in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generation device. Background technique [0002] Wind energy and photovoltaics - as one of the new energy sources closest to the cost of thermal power today, has very broad development prospects. The national "13th Five-Year Plan" will also promote the implementation of wind power grid parity. In China, wind energy and solar energy are used as supplementary energy to traditional energy; however, in foreign countries, wind energy has already become one of the mainstream energy sources. Germany's wind energy meets about 10% of energy demand, and Denmark's proportion has exceeded 50%, but the domestic wind power generation system cannot be widely promoted, partly because of the low wind capture efficiency of wind turbines, and partly because of the low starting torque , it is difficult to start; some are due to poor wind resistance, which affects the use....
