Abstract

A telescopic wind power generation device comprises a cabin and blades, the blades are fixed to the cabin, the interiors of the blades communicate with the interior of the cabin, and the blades comprise the first-stage blade, the second-stage blade, the third-stage blade and a telescopic rod. The first-stage blade is internally provided with a first-stage guide rail, the second-stage blade is internally provided with a second-stage guide rail, a limiting plate is arranged on the second-stage guide rail, the second-stage blade can slide along the first-stage guide rail, the third-stage blade can slide along the second-stage guide rail, the top end of the telescopic rod is fixedly connected with the third-stage blade, the third-stage blade is driven to slide on the second-stage guide rail, and the limiting plate can limit the sliding distance of the third-stage blade on the second-stage guide rail. When the telescopic rod contracts, the third-stage blade can slide along the second-stageguide rail, is contracted into the second-stage blade and is further contracted along with the telescopic rod, the third-stage blade is limited by the limiting plate and cannot continue sliding on thesecond-stage guide rail, and the second-stage blade and the third-stage blade are integrally contracted into the first-stage blade along the first-stage guide rail.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a retractable wind power generating device. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind is a non-polluting energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. With the advancement of blade materials and manufacturing technology, the power of wind power generation devices is increasing, and the length of large wind power blades can reach nearly 100 meters long. The application of large-scale wind power blades improves the efficiency of wind energy capture, but their wind resistance is very considerable. When encountering severe and strong winds, the blades will be damaged. For example, in July 2014, typhoon "Wamasun" caused 15 wind turbines in Zh...
