Description
Affiliated technical field:
The utility model provides a kind of hydraulic control equipment of vertical axial wind driven generator integrated form pressure oil-source device.It belongs to the hydraulics field, can be applicable among the vertical axis aerogenerator hydraulic control system.
Background material:
Because to the further investigation of vertical axis aerogenerator, its wind energy conversion efficiency is constantly higher, discovery might approach the potentiality of horizontal axis wind-driven generator, has therefore caused the strong interest of people to it.Because vertical axis aerogenerator still is in the low power range at present, the mounting type of wind wheel blade is fixed, can not rotate, and is an impediment to the wind energy conversion efficiency and further improves.Along with the single-machine capacity of vertical axis aerogenerator constantly increases, the demand that improves the wind energy conversion efficiency seems important all the more.The mounting type of wind wheel blade is by the fixed rotary type that is improved to, and drives the development trend that is inevitable by hydraulic control mode.Therefore, hydraulic control equipment of vertical axial wind driven generator should be the problem that must consider with the pressure oil-source device.
