[0003] The distribution of wind resources is extensive and abundant. Due to the great difference in wind power at different heights in different seasons, the height of the blades of current wind power generation equipment is fixed and non-adjustable, and cannot be at the position with the largest wind resources at any time to achieve the maximum utilization of resources. Therefore, it causes waste of energy and low power generation efficiency

The invention relates to wind power generating equipment capable of improving power generation efficiency. The equipment comprises a base, a primary tower barrel, a secondary tower barrel, a shaft base, a hub, blades and a tail wing, wherein the secondary tower barrel also comprises a telescopic mechanism and a stabilizing mechanism; the telescopic mechanism comprises a first motor, a worm, a worm gear, a lead screw, a sleeve and a fixed assembly; the fixed assembly comprises a fixed block and a fixed rod; the stabilizing mechanism comprises two stabilizing assemblies; and each stabilizing assembly comprises a driving chamber, and a second motor, a driving wheel, a driving rod, a driving block, a stabilizing rod and a guiding unit which are positioned in the driving chamber. According to the wind power generating equipment capable of improving power generation efficiency disclosed by the invention, the height of the blade on the wind power generating equipment is adjusted up and down by the telescopic mechanism, which is beneficial for adjusting the optimal height of the blade according to distribution of wind power, the utilization maximization of wind power resources can be realized, and the power generation efficiency is improved; and meanwhile, after the height is adjusted, the stabilizing mechanism works, so that the stability of the blades is improved, and the shaking of the blades is avoided when the wind is too intense.
Description
technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a wind power generation device for improving power generation efficiency. Background technique [0002] Wind power generation equipment is a power device that converts wind energy into mechanical energy, which drives the rotor to rotate, and finally outputs alternating current. In recent years, wind power generation equipment has been used as a power source to replace human and animal power, and has played an important role in the development of productivity. [0003] The distribution of wind resources is extensive and abundant. Due to the great difference in wind power at different heights in different seasons, the height of the blades of current wind power generation equipment is fixed and non-adjustable, and cannot be at the position with the largest wind resources at any time to achieve the maximum utilization of resources. As a result, energy is wasted and powe...
