Automatic control wind sail type swing wing vertical shaft wind motor

Abstract

The invention relates to an automatic control sailing wind generator which comprises: wing foil (1), cross bar (3), wing crank (2), driving vertical axis (7), tower (6), generator (8), overriding clutch (9), centrifugal clutch (10), speed increasing gear (11). It is characterized in that the wing foil (1) comprises wing tip (14), wing panel (17), wing segment (16) and wing root (18). In the wing panel installed a feathering mechanism, in the wing root installed a feathering mechanism and swing mechanism; in the wing crank installed a control device and an over speed feathering sensor. The feathering mechanism can ensure the simultaneous feathering and unloading of each wing foil, in the case of over speed or typhoon, the swing mechanism can ensure to start at low speed and smooth speed automatically. The invention also adopts the sloping drawing wire (5) to draw the wing foil (1) and the cross bar (3), the sloping drawing wire (12) and (13) take each cross bar and the steel cable (4) draws the power (6) to the ground to make the system stable.

Description

technical field [0001] The invention relates to a self-controlled sail-type swing-wing vertical-axis wind turbine. Background technique [0002] The inventor's patent No. <98111548.9> has been able to ensure the automatic start of the wind turbine, and maintain the rated speed after reaching the rated wind speed; when encountering a typhoon, the blades will automatically feather, and the wind turbine will be unloaded to ensure safety through the typhoon; the vertical shaft, There is no windward mechanism, the speed-increasing gear and the generator are on the ground, and the maintenance is convenient, so the structure is simple, the weight is light, and the manufacturing cost is very low, but its efficiency is low, and the speed ratio is also low, and its wings and horizontal bars are cantilever beam structures , the bending distance at the root is very large, which requires a bulky structure, and the feathering mechanism cannot ensure that the wings are feathered sync...
