Double-layer reverse rotation vertical-shaft wind-power machine using horizontal combination active wing

Abstract

The invention discloses a novel vertical spindle wind machine which is mainly formed by support devices, vanes and the like that are respectively arranged on an upper layer and a lower layer and are almost completely the sane as each other; the wind machine also comprises a movable wing link gear, a speed governing device, a rhachis, a locating device, a limiting device, an auxiliary limiting device and an auxiliary starting device. The movable wing link gear adopts a labile equilibrium form to lead the vane group to easily open and shut, so as to not only ensure the best holding state, but also reduce the requirements for the manufacturing materials, thus greatly improving the cost performance of the wind machine; the machine adopts simple and effective mode of mechanical speed regulation, so as to absolutely ensure the service life of the wind machine; all movable linking parts of the machine are in a state of sealing, so that rain, snow dust and sand are avoided damaging the wind machine; as the machine is designed to be a form of double-layer reverse rotation, the utilization rate of wind energy can be improved, and the torsional force of the whole machine can be reduced; meanwhile, the machine is provided with a device which can keep the whole machine flat, so that the whole machine can be easily put down when being necessary, and the novel vertical spindle wind machine is more suitable for ships. When in design, the processing technique and installation technique are fully taken into consideration, so that the invention is suitable for commercial process.

Description

technical field [0001] The invention relates to a wind energy utilization device, in particular to a double-deck counter-rotating vertical-axis wind turbine using horizontal combined movable wings. Background technique [0002] The development and utilization of wind energy has attracted people's attention day by day. In order to further improve the utilization rate of wind energy, the vertical axis wind turbine is undoubtedly a better model than the horizontal axis wind turbine. Therefore, humans have been trying to manufacture vertical-axis wind turbines since the 1950s, and an inventor in the United States has also created a large vertical-axis wind turbine with a diameter of 50 meters. But, although people's research on the vertical axis wind turbine has continued for more than half a century, there has been no breakthrough progress. According to the information from various aspects, the deficiencies of the current known public vertical shaft wind turbines mainly lie i...

Problems solved by technology

However, in this way, the manufacturing cost will inevitably be greatly increased; if it is a side-shaft type, the wind turbine may not be able to return to the best standby state after each shutdown, and dirt is easy to accumulate on the lower end of the wing shaft , will inevitably cause poor operation... All in all, this machine has not completely jumped out of the traditional mode of known vertical axis wind turbines
