Double sets of pole liftable vertical wind turbines

Abstract

The invention discloses a double-loop-bar vertical wind power generator capable of ascending and descending. The double-loop-bar vertical wind power generator comprises an outer bottom push rod, an inner bottom push rod, an outer telescopic push rod and an inner telescopic push rod, wherein the inner bottom push rod is arranged inside the outer bottom push rod, the outer telescopic push rod is glidingly inserted and arranged between the outer bottom push rod and the inner bottom push rod, the inner telescopic push rod is glidingly inserted and arranged in the inner bottom push rod in a sealing way, a blade assembly capable of being vertically folded in the inner telescopic push rod is glidingly arranged in the inner telescopic push rod in a sealing way, the upper end of the inner telescopic push rod is coaxially connected with the upper end of the outer telescopic push rod through a bearing in a way capable of relatively rotating, a clamping and connecting assembly used for fixing the relative position between the inner telescopic push rod and the inner bottom push rod is arranged between the lower end of the inner telescopic push rod and the upper end of the inner bottom push rod, the lower end of the inner bottom push rod is respectively provided with an air inlet assembly and an air extracting assembly in a sealing way, the air inlet assembly and the air extracting assembly are respectively communicated with an inner cavity of the inner bottom push rod, and the bottom surface of the inner bottom push rod is connected with a power generating assembly capable of being communicated with an electric network. The double-loop-bar vertical wind power generator is applicable to a power generating device.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a vertical wind power generator with double sets of poles that can be lifted and lowered. Background technique [0002] With the advancement of social and cultural life and people's emphasis on green energy, wind energy has been gradually used by people as a clean energy. Its low-carbon, environmentally friendly and renewable characteristics have made more and more people realize the potential of this energy. More and more wind power generation devices have also emerged as the times require. [0003] Existing wind power generation devices generally have the following problems: [0004] Since the wind power generation device is generally a fixed structure that cannot be raised and lowered, the wind blades of the wind power generation device are always at a high altitude, so that when encountering extremely bad weather, the wind blades and connecting bearings of the wind power gen...
