Description

Corrected replacement page M410107 on March 30, 100. 5.· New description: [New technical field] [0001] This creation is about a rotating wheel structure for fixed blades of wind turbines, especially for fixed blades. The structure of the rotating wheel is improved, and the utility model has the advantages of simple manufacture, good structure, light weight, light starting force and good efficiency. [Prior Art] [0002] According to the wind power generator, it is a renewable energy source, because renewable energy does not exist.

In the possibility of energy depletion, so under the dual pressure of conventional energy emergency and ecological environment deterioration since the oil crisis, the benefits have been valued by many countries, especially the energy shortage of the country’s power to smash the key to the use of air flow Pushing the windmill to rotate, the windmill turns to $Fafa's 'Electricity' to generate electricity. Because wind energy is a non-polluting and renewable new energy source, it has great potential for development, especially for coastal islands, remote mountainous areas with inconvenient transportation, sparsely populated grassland pastures, and rural and frontier areas. As a reliable way to solve production and life: energy, even in developed countries, wind energy as a high-policy clean new energy is also benefited. The structure of the conventional wind power generator is mainly that one end of the transmission shaft of the fixed generator is fixed to a blade drum, and the circumferential surface of the drum is fixed to the turbine blade which is radiated outward. Among them, the blades are driven by the wind to convert the wind energy into mechanical energy, which drives the drive shaft of the generator to rotate; the generator converts the mechanical energy into electrical energy, and outputs power through the power conversion system for power storage or use. In the above wind power generator, the blade is radiated outward from the periphery of the drum, and the center portion of the blade drum is replaced by a near-axis, the torque form number A0101, page 3/12 pages, M410107, March 30, 100, and the correction is small, and Turbine blade >{ directly fixed on the drum of the generator drive shaft, the number of turbine blades is small (about 3-6 pieces), which will result in the lack of effective area and lack of efficiency. In order to improve the above-mentioned missing, only the length of the blade is increased to increase the torque and increase the area of the wind. However, the change of the blade structure strength is required, and the blade does not break, but the weight is increased, and the wind is large. It can be started. Therefore, the blade provided in the near-axis portion of the wind turbine of the conventional wind power generator has a small torque, a low efficiency, and a large wind blocking area, and the windmill has low rotation efficiency and a large lack of starting wind force exists.

This creator has been designed and improved in view of the fact that the wind turbines have the above-mentioned lack of application in the application, and this creation has not been produced. ·. ·:. ..;

[0003] The main purpose of this creation is to provide a rotating wheel structure that is simple in construction, good in structure, light in weight, large in torque, large in wind blade area, and small in wind turbine fixed blades. The main feature of this creation is that the drum is connected to one end of the generator drive shaft, and the radially arranged wires on the outer edge of the drum are connected to the inner surface of one wheel, and the turbine blades are fixed on the outside of the wheel. With these settings, the small torque part of the wind turbine shaft center is a radially arranged steel wire. The part of the wind blocking area is small, and the lateral wind can pass smoothly, the wind resistance is small, and the weight of the windmill can be reduced. The outer part of the rim with a large torque is installed with the blade, so that the windmill is light, the starting wind is small, the torque is large, and the efficiency is high.

M410107 » I On March 30, 100, according to the replacement section and its structure, the following examples are given. Referring to Figures 1 to 4, the components of the wind turbine are mainly composed of a generator 10, a rotating wheel 20 (i.e., a windmill) fixed to one end of the propeller shaft 1 of the generator 10, and a The power output from the generator 10 is composed of a power conversion system for voltage transformation, rectification, output or storage, and is supported by a support column as a whole. The rotating wheel 20 mainly includes: a drum 2 1 is fixed to one end of the transmission shaft 1 1 of the generator 10; a wheel 2 2, also shown in the fifth figure, is located on the drum 2 1 The outer side is arranged coaxially with the drum 2 1 , and is made of a high-strength and light-weight composite material or a light alloy (such as a combination of gold, release, and alloy); 2 3, the IT-like shape > column is fixed between the drum 2 1 and the rim 22, one end is fixed to both ends of the circumferential surface of the drum 2 1 , and the other end is fixed to the center position of the inner end of the rim 2 2 , the steel wire 2 3 At the two ends of the drum 2, the left and right sides are placed at the left and right sides, and the rim 22 is stably supported and fixed; and the plurality of supporting blades 24 are arranged in a radial manner. The uniform configuration is fixed to the outside of the rim 22, and is fixed at an angle with the rim 22. When the above components are sequentially assembled, as shown in the first and second figures, the wind driven blades 24 rotate, so that the drum 2 1 drives the transmission shaft 1 1 of the generator 10 to rotate synchronously, thereby making the generator 10 Power generation to achieve the effect of wind power generation. Since the creation has the following improvements in structural design, the following effects are derived. 1 · Rotating wheel 2 0 (windmill) axis part (that is, the form number A0101 with a small torque is 5th page/12 pages, revised on March 30th, 100th). It consists of steel wire 23, The partial wind resistance area composed of the steel wire 23 is small, and the lateral wind force is easily passed by the gap between the steel wires 23, so that the wind resistance of the rotating wheel 20 is reduced; and the wind resistance area is small, and the entire rotating wheel is also reduced. The weight of 20, plus the rim 22 is also hollowed out, and is made of composite material or light alloy. Therefore, the rotating wheel 20 is light in weight and the starting wind is small; the axial part has a small wind resistance area and undertakes wind power. The blades 24 of the energy are installed outside the rim 22 having a large torque, and are arranged in a plurality of pieces, and the wind receiving area is large, resulting in high efficiency. 2. The rim 22 is evenly supported by the left and right wires 23, ’

Not only is the support structure good, but the balance of the rim 2 2 can be adjusted by adjusting the wire 2 3 to make the rotation of the rotating wheel 20 more stable and not eccentric. As can be seen from the above description, this creation is not only creative, but also has industrial use, and proposes a new type of patent application according to law. However, the above is only a preferred and feasible embodiment of the present invention, and all equivalent structural changes using this creation should be covered by the scope of the present invention.
