Abstract

A stacked three-dimensional wind-driven power generator is characterized in that a horizontal-shaft wind-driven power generator is disposed on a tower cylinder, and the shaft end of the horizontal-shaft wind-driven power generator is fixedly connected with the blades of the horizontal-shaft wind-driven power generator; the tower cylinder is fixedly connected with a vertical-shaft power generator support cylinder seat through upper and lower support rings disposed between the outer wall of the tower cylinder and the cylinder inner wall of the vertical-shaft power generator support cylinder seat, the upper-end and lower-end outer walls of the cylinder of the vertical-shaft power generator support cylinder seat are hinged to a rotation outer cylinder through thrust bearings, the blades of a vertical-shaft wind-driven power generator are fixed at the upper and lower ends of the rotation outer cylinder through evenly-distributed and fixedly-connected support rods, an upper cover plate is fixedly connected with the upper end of the rotation outer cylinder, a driven gear and the rotor of the vertical-shaft wind-driven power generator which are coaxially and fixedly connected are mounted at the upper and lower ends of the vertical-shaft wind-driven power generator support cylinder seat through bearings, and the inner drive teeth disposed at the upper and lower ends of the rotation outer cylinder are meshed with the driven gear; a brake device is disposed between the cylinder wall of the vertical-shaft wind-driven power generator support cylinder seat and the inner wall of the rotation outer cylinder.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and relates to a stacked three-dimensional wind power generator. Background technique [0002] According to the results of the third national wind energy census by the China Meteorological Administration, the onshore technically developable area is 200,000 km 2 (The wind power density is 150W / m 2 ), of which 2.548 billion KW can be developed by wind energy resource technology at a height of 10m (the National Climate Center used numerical simulation methods to evaluate China's wind resources in 2006), and the exploitable wind energy resources at a height of 50m above the ground in China reached 1.4 billion KW (2005 The United Nations Environment Program adopted a numerical simulation method in 2010), and the near-ground wind resources are extremely abundant. [0003] In the field of wind power generation, the existing technology mainly adopts the following three methods to increase...

Problems solved by technology

[0004] The above-mentioned three ways of setting up wind turbines have improved the utilization efficiency of near-earth wind resources to a certain extent, but there are still many problems: (1) The power generated by the combined vertical axis generator is small, and the combined type of more than 1.5MW Vertical axis wind turbines are difficult to realize, and the utilization rate of wind resources at high altitudes (above 50m) is 0; For wind turbines, the structural weight increases greatly, and the wind receiving surface increases at the same time. The uneven wind speed causes the deflection of the force on both sides of the tower to be different. (3) The method of alternately arranging the vertical axis and horizontal axis wind turbines in the wind field needs to add a whole set of equipment for the vertical axis wind turbines, and the bottom blades of the horizontal axis wind turbines rotate at the lowest point to There is no improvement in the utilization of wind resources in the 25-30m space between the ground surface. At the same time, during operation, the wakes of the horizontal axis wind turbine and the vertical axis wind turbine interfere with each other and cause power fluctuations. The real-time operation adjustment of the wind turbines is proposed. higher requirement

So far, there are no literature reports and practical applications of stacked three-dimensional wind turbines with vertical and horizontal shafts
