Abstract

The invention provides a wind power generation device with blades capable of achieving self-adjusting protection. The wind power generation device comprises a shaft part, wind power generation bladesand elastic protection devices making the wind power generation blades rotate and move. Fixing shafts movably connected with the bottom edges of the wind power generation blades are arranged on the shaft part, and the fixing shafts are in a J shape and are divided into long shafts and short shafts. Each elastic protection device comprises a connecting curve ring penetrating through the corresponding wind power generation blade, a spring and an anti-sliding piece, wherein the spring is arranged on the connecting curve ring is a sleeving mode, one end of the connecting curve ring penetrates through an open hole in the corresponding wind power generation blade and is sleeved with the anti-sliding piece to be fixed, and the other end of the connecting curve ring is fixed to the short shaft ofthe corresponding fixing shaft. When wind force is too large or the wind direction changes suddenly, the wind power generation blades compress or release the springs to adjust self-angles to protect against damage and adjust the area, subjected to wind pressure , of the blades, and stable working is ensured. The wind power generation device is light in structure, not prone to damage, convenient toinstall, low in labor cost, high in wind power resource utilization rate, low in manufacturing cost and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generation device whose blades can be self-adjusted and protected. Background technique [0002] With the continuous development of social economy, the electricity consumption in various fields is constantly rising, and it is difficult to meet people's electricity demand by using firepower, waterpower and other resources to generate electricity. Therefore, more and more people begin to pay attention to the wind energy. A clean renewable energy, in order to increase power generation and ensure the smooth progress of various social activities. [0003] Wind power generation uses wind power to drive wind power generation blades to rotate. The wind power generation blades are connected to a speed increaser, and the speed increaser increases the speed through the speed change mechanism to drive the generator cabin to generate electricity. Obviou...
