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...

Problems solved by technology

[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 blown into the rotor blade from the guide air duct of 2 to 3 blades, driving the rotor blade to rotate, thus The rotor blade shaft drives the generator to rotate, so as to achieve the purpose of generating electricity; the invention patent published by Huang Diangui et al. (application number 200810034101.5) discloses a wind power generation device with energy-gathering-shading expandable curved blades. Equipped with an air inlet guide device, the air inlet guide device is composed of several energy-gathering-wind shields arranged symmetrically around the center of the rotor to form a contracted airflow channel for the intake air to increase the wind speed, thereby improving the utilization rate of wind energy; published by Li Siqing et al. A utility model patent (Patent No. ZL 200720063104.2) discloses a cyclone-type wind power generator, which improves the utilization efficiency of wind energy by setting a fairing, wind gathering cover and wind deflector; a utility model patent disclosed by Wang Hongbin (Patent No. ZL 200720012724.3) Disclosed is a fan blade of a wind-collecting type wind power generator, which improves the utilization efficiency of wind energy by arranging structures such as a wind-collecting box, a wind-collecting box, and an air-collecting direction-regulating partition

[0010] Based on the literature review, it can be concluded that the reported wind gathering (or wind collecting) devices to improve the wind energy utilization efficiency of vertical axis wind turbines are all fixed relative to the base of the wind turbine, and cannot automatically adjust the angle according to the wind direction
