Power generation device

Abstract

The invention discloses a power generation device to thoroughly solve the problem of the rotating overpseed of generator sets. The power generation device comprises a stand column and at least one generator set located on the same column. Each generator set comprises a support, blades connected with the support and a generator rotationally generating power through the blades. Each generator set further comprises an adjusting device located on the support, wherein the adjusting device is used for moving or rotating the blades so as to adjust the windward area of the blades according to the windspeed. By means of the wind power generation device, when the wind force is too large, the effective windward area can be reduced to zero, the stability of the device and applicability of the devicein various environments are improved, and the service life of the device is prolonged. A solar cell panel can be laid on the outer surface of the power generation device, the device can collect wind energy and solar energy at the same time, and wind force and solar energy combined power generation is achieved. All the parts of the generator sets in the power generation device are directly connected with the stand column or directly connected with the stand column through bearings, demounting and assembling are convenient, application and popularization are facilitated, and very high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a power generation device for wind energy and solar energy combined power generation. Background technique [0002] Wind turbine is a kind of power generation equipment that is both environmentally friendly and relatively low in power generation cost. At present, the horizontal axis propeller wind turbine is widely used. The rotating shaft of this type of wind generator is set horizontally, and the blades are driven by the wind to convert the wind into electrical energy. However, the structure of the control system of this type of wind generator is complex and technical The difficulty is high, large-scale units have high requirements on materials, and the manufacturing cost is very high, which is not conducive to the popularization and wide application of wind power generation. Compared with the defects of horizontal-axis wind turbines, vertical-axis wind turb...

AI Technical Summary

Problems solved by technology

At present, there are many new wind power generator patents for controlling the overspeed rotation of fans, such as CN 102094761 A, which discloses a wind power generator with a vertical axis, but the wind receiving area of ​​its blades is extremely limited, and the wind energy in the start-up stage The utilization rate is low; when the wind speed is high, the centrifugal force is used to expand the blades outward, increasing the moment of inertia, and limiting the speed to prevent the fan from rotating overspeed

However, this method cannot reduce the wind receiving area of ​​the fan to zero, so it cannot fundamentally solve the problem of overspeeding of the fan in strong wind or stormy weather, and this method will also increase the overall lateral wind receiving area of ​​the fan. The wind speed makes the wind turbine more likely to shake, become unstable, and even risk overturning and damage
