Self-navigation wind gathering device for vertical axis wind driven generator

Abstract

The invention discloses a self-navigation wind gathering device for a vertical axis wind driven generator. A wind gathering frame is provided with an upper bearing sleeve and a lower bearing sleeve which are close to a circle center part, and the bearing sleeves are connected to a main axis of the vertical axis wind driven generator through an upper bearing and a lower bearing. A front wind gathering plate, a side wind gathering plate and a balance rod which can radially move along the wind gathering frame are vertically distributed inside the wind gathering frame, wherein an included angle alpha between the front wind gathering plate and a Y axis in a negative direction is 30-70 degrees; an included angle beta between the side wind gathering plate and an X axis in a positive direction is0-90 degrees; included angles theta1 and theta2 between both side plates of an empennage and the Y axis in the positive direction are 0-30 degrees; and the empennage is arranged above the wind gathering frame. The self-navigation wind gathering device for the vertical axis wind driven generator has reasonable structure, and compared with a vertical axis wind driven generator without the wind gathering device, the self-navigation wind gathering device for the vertical axis wind driven generator can effectively improve the rotating speed of blades of the vertical axis wind driven generator, thereby improving the utilization rate of wind energy by 100-150 percent.

Description

Technical field: [0001] The invention relates to the field of wind power generation, in particular to a self-navigating wind gathering device for a vertical axis wind power generator. Background technique: [0002] Human beings have used wind energy for thousands of years. However, limited by the development level of productivity and science and technology, the utilization of wind energy has not attracted enough attention and interest. With the maturity of other energy applications and people's concerns about energy depletion, especially the oil crisis in the 1970s and the nuclear power and environmental crisis in the 1980s, people once again realized the importance and importance of developing renewable energy. The urgency of wind power generation has gradually attracted people's attention due to its many advantages compared with traditional energy sources such as its own renewability and environmental protection, thus promoting the development of wind power generator tech...

[0009] After searching the literature of the prior art, it was found that the utility model patent (Patent No. ZL 200720084077.7) disclosed by Wang Zhengyi discloses a wind lifting device. By setting a conical tube and its auxiliary structure, the narrow tube effect of the cone is used to improve the wind power. The wind speed on the blade improves the utilization efficiency of wind energy, but the device needs to manually adjust the direction of the conical tube according to the wind direction, which is inconvenient to use; the invention patent (application number 200710066022.8) disclosed by Gao Tianrong et al. A trumpet-shaped wind collection hood is set to improve the utilization efficiency of wind energy; the invention patent disclosed by Wang Qi et al. (application number 200710171834.9) discloses a vertical axis wind wheel device with wind speed boost and double flow guide. The utility model patent (Patent No. ZL 200720067635.9) disclosed by Shao Boran and others discloses a new type of wind energy generator, which reduces the wind energy by setting a semicircular windshield at the outer end of the blade Reverse rotation force, the windshield can ensure that only one side can be rotated by the wind, and the wind energy can be utilized to a greater extent, thereby improving the utilization rate of wind energy; the invention patent (application number 200810055205.4) disclosed by Zhang Guanglei et al. In the high-speed wind power generation device, 6 to 8 fixed blades are evenly distributed around the rotor blades with the rotor shaft as the axis. No matter what the wind direction is, it will always be blo
