Description
Technical Field
The present invention relates to a wind power generation apparatus, and more particularly, to a wind power generation apparatus capable of generating rotational wind.
Background
Currently, wind power generation is generally classified into a horizontal axis generator set and a vertical axis generator set according to the structure.
1. For a horizontal axis genset:
① The device has the advantages of compact structure, mature technology, safety and reliability.
② The horizontal shaft has the defects that the direction of rotation of the wind wheel is adjusted by adjusting the direction of wind (also called yaw and deflection), so that the structure is complex, the transmission and generator set is arranged in a working machine bin positioned at the top of the tower, large parts cannot be replaced and maintained inconveniently, the manufacturing cost of the blades, bearings and gear boxes of the horizontal shaft set is very high, the whole set is basically damaged and scrapped if a large fault and typhoon happen, great economic loss is caused, the horizontal shaft set has extremely high requirement on the installation foundation, and the fan blades cut wind when the wind turbine set works.
The wind power generation system has the advantages that the utilization rate of natural wind energy is low, the wind power generation system is generally limited to wind power generation in horizontal wind directions (wind energy of incoming wind in various directions is not uniformly utilized), the wind power can be utilized only in one plane, wind power synthesis is not performed, the wind power is converted into vortex wind direction development which continuously enhances the rotation torque force like a tornado, so that larger energy is further obtained, the wind wheel is pushed to rotate, the power generation efficiency is furthest improved, the defect in the aspect of power generator system facilities also exists, a wireless Internet of things automatic remote video monitoring system is not realized by using an inexpensive wind power generation and power supply mode, the running condition of each wind power generator is managed by an all-weather 24-hour video automatic monitoring mode, and meanwhile the problems of lightning protection, theft prevention, fire prevention and the like in jurisdiction are solved, and the safety protection is further improved, and the running cost is reduced.
2. For a vertical axis wind turbine:
① The vertical axis wind turbine generator system has the advantages that the vertical axis wind turbine generator system can receive incoming wind in any direction, a yaw device of a wind wheel is not required to be arranged, and the mechanical transmission and generator system can be installed on the ground and is convenient to maintain.
② The vertical axis wind generating set in the current market has the defects that the wind energy utilization coefficient is not high, the available wind energy is limited due to the small volume and is difficult to start by self due to dead weight when the volume is slightly larger. For a large vertical axis wind turbine, the complex problems of gravity friction, dynamic balance during rotation of a main driving structure and the like need to be solved, and the vertical axis wind turbine cannot be enlarged with the current technical level.
In addition, in the field of wind power generation, the wind generating set is of a horizontal shaft type active wind-aligning type, the length of a blade of the wind generating set is long, and the length of a single blade of the wind generating set is over 40 meters by taking a 3MW set with the best economical performance as an example. The method for increasing the capacity of the single wind power engine unit mainly increases the length of the blades, and the length of the blades is continuously increased, so that the method is limited by the strength of the blades, and the manufacturing cost of the engine is increased. How to obtain larger power without increasing the size of the engine motor is one of the research directions in the field of wind turbines.
The patent number CN201120318357.6 discloses a wind-gathering fan, which is characterized in that a gradually-expanding conical wind-gathering short cylinder is sleeved on the periphery of a turbine blade, and the front-back caliber ratio of the wind-gathering short cylinder is only 1.3 times, but the generated energy can be improved by three times by adopting the fan. The blades can obtain more energy by means of the wind-collecting short cylinder. Because the length of the turbine blade is longer, the wind-collecting short cylinder needs to be sleeved on the periphery of the turbine blade, so that the wind-collecting short cylinder is huge in volume and heavy in weight. Therefore, such a wind turbine can be installed only on a low ground, but cannot be installed on a mountain or a high-rise building. The application range is limited. Because the wind collecting short cylinder is sleeved on the periphery of the long and heavy turbine blade, the whole weight is heavier, the turbine and the wind collecting short cylinder cannot rotate along with wind, only wind energy in a single direction can be utilized, and the utilization rate of the wind energy is not high.

the device can regulate unidirectional incoming wind into whirlwind with rotary power, and the whirlwind plate is converted into stable horizontal wind power output through a special arc passage, wherein the basic included angle between the air inlet plate 1 of the ① main receiving wind plate and the whirlwind plate 2 of the ② arc main body is 130 degrees (adjustable), and the length ratio of the main receiving wind plate to the arc main body is 1:5.
The device utilizes an omnibearing vertical wind-guiding wind-collecting device with a main body in a three-page structure to collect and guide wind power in a nearly vertical mode, and the page of the device guides natural wind into the device as much as possible by a specific design curved surface to improve the wind power utilization rate. Natural wind enters the device from the air inlet plate 1 of the ① main air receiving plate, which accounts for four fifths of the whole flow, and the rest five-fifth flow enters from the turbulent flow opening of the ③ turbulent flow plate 8 and generates wind power difference with the main air inlet to form a rotary vortex. And then the rotary wind power is guided to ④ rotary wind output port 4 and the outlet of wind collecting pipe 12 by the arc-shaped guide bar (groove) downwards. ② The cyclone plate 2 is a curve auxiliary rib plate of the arc-shaped main body, and wind power adjustment is needed through the guide strips and the spoiler because natural wind power has uncertainty of incoming direction.

The device designs that the normal working wind speed interval is 3-28 m/s. The invention also considers that the main wind receiving plate and the spoiler can adjust the wind inlet angle due to different conditions of wind farms in each place, the adjustable included angle between the main wind receiving plate and the main body is about 15 degrees, the spoiler can be adjusted to 21 degrees, the fixed flow output after the matching of the wind inlet of the main wind inlet and the wind quantity of the spoiler is ensured, the series of adjustable wind discharging openings are designed on the main arc-shaped backboard, and the influence on the device caused by super typhoons is avoided
