Description

Wind power generator

The present invention relates to a wind power generation device, and more particularly to a technology for fixing to a fixed object or an object moving at a speed, thereby effectively generating electricity and improving assembly and maintenance convenience.

As previously known to us, a conventional wind power generation device, such as Patent No. 092215285, patent name: Turbine wind power generation device, is a structural improvement of a turbine type wind power generation device, which includes a turbine ventilator and a transmission system. , gearbox, generator and tower; characterized in that: the turbine ventilator is a fixed shaft that is arranged at the center of the frame body, the frame body is round tubular and is provided with a plurality of reinforcing ribs at the top end of the fixed shaft and the frame body The upper part is provided with a blade seat, the blade seat is circular, and a bearing is arranged at the center thereof, and the bearing is fixed to the fixed shaft, and a gear is superposed and fixed under the center of the lower blade seat, and the gear can be combined with the lower fan blade The seat rotates synchronously, and a spiral blade is fixed on the side of the upper and lower blade seat, and a lightning protection device is arranged at the top of the fixed shaft above the upper blade seat. The entire turbine ventilator is fixed to the upper end of the tower by the frame body. A control box is installed under the tower seat, and the control box has a gearbox and a generator. This is a patented structure.

However, the lack of the conventional wind power generation system is:

1. The wind power generation device needs to be fixed at a fixed fixed point, and then the airflow rising in the natural environment causes the turbine ventilator to rotate naturally to drive the generator to rotate to generate electric current, and generally the turbo ventilator is fixed on the air ventilator. At a height, the wind power installation is required to operate in accordance with the conditions of nature, which is limited by its environment and height.

2. When there is no airflow in the environment or the air volume is weak, the speed at which the turbo ventilator cannot rotate or rotate is relatively slow without generating a power source.

However, the absence of this patent is based on:

1. As shown in the second diagram of the bulletin, the wind power generation unit is installed on the electric vehicle, and the expansion is not sufficient only on the electric vehicle.

2. Please refer to the bulletin 21, the wind power generation unit as a whole is flat, so that the wind power generation unit and the windward surface are planar, that is, the plurality of fan blades of the wind power generation unit and the electric vehicle are mutually Vertically, although the wind power generation unit can supply power to the electric vehicle during power generation, the vertical wind power generation unit generates a lot of wind resistance when the wind power generation unit travels on the electric vehicle.

3. The wind collecting device is provided with a servo motor and a damper, and the collecting device is a combination of a plurality of components, and has a relatively high cost.
