A typhoon-resistant marine wind power generation platform with foldable blades

Abstract

The invention discloses a typhoon-resistant marine wind power generation platform with foldable blades in the technical field of wind power generation, including a generator connected to an installation cylinder through a first rotating shaft, and a U-shaped Fixed seat, the U-shaped fixed seat is connected with a second rotating shaft, the outer wall of the second rotating shaft is provided with a movable seat, one end of the second rotating shaft is connected with a turntable, a connecting rod is hinged on the rotating disk, and a telescopic device is hinged at the other end of the connecting rod, and the movable seat There is a mounting groove on the top, a blade shaft is arranged in the mounting groove, a driven gear is provided on the outer wall of the blade shaft, and a driving gear is meshed on the driven gear, and a mounting plate is provided on the other side of the blade shaft, and the blade is fixedly connected to the mounting plate. The structure design of the invention is reasonable. By rotating the mounting plate, the wind-receiving area of ​​the blades can be changed, so as to prevent the blades from rotating too fast, which may cause overloading of the generating set. A fixed seat and a movable seat are arranged, and the movable seat can be rotated to fold the blades, avoiding the breakage of the blades, and realizing Protection of wind turbines.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a typhoon-resistant marine wind power generation platform with foldable blades. Background technique [0002] As onshore wind resources have entered a saturated state, offshore wind resources have higher wind speed, low turbulent intensity, and stable wind direction, so that offshore wind turbines have better output power. In addition, offshore wind farms are close to developed coastal cities, which can slow down the energy demand of coastal cities. The vast sea area does not have advantages such as occupying land. Therefore, the development of offshore wind power has attracted more and more attention. [0003] Compared with land-based wind turbines, offshore wind turbines generally use larger wind turbines. Large-scale wind turbines are conducive to improving the utilization coefficient of wind energy, reducing the cost of infrastructure such as towers, and reducin...
