Abstract
A double-set blade-switching high-power wind power station belongs to a wind power generation technical field and mainly solves problems of low utilization ratio, large volume, low generated output and easy damage upon strong wind of conventional wind power generating equipment. The double-set blade-switching high-power wind power station includes wind-driven blades, a generator, a wind rudder and a supporting column and is characterized in that a movable pillar (5), a support (4) and a rudder (2) are disposed on the supporting column (6); two generating sets (3) are connected by the support (4); the lower blade is driven by the wind to rotate upwards; and two sets of blades (1) are opened and closed under the control of the wind. An output power of the double-set blade-switching high-power wind power station is beyond twice the sum of the output power of two conventional power generating equipment in a size equal to the high-power wind power station, that is to say, the output power of the double-set blade-switching high-power wind power station is beyond four times that of unit power generating equipment in the size equal to the high-power wind power station. The double-set blade-switching high-power wind power station is applied to windy occasions and is adaptive to a manufacturer of the wind power generating equipment.
Description
Technical field: the utility model belongs to technical field of wind power generation.
Technical background: the many employings of wind-power electricity generation in the prior art are lateral rotation formula air blade and fixed Blade Design down with the wind, in reality is used, are used widely, are suitable for the bigger area of wind-force and use.
Summary of the invention: the utility model solves mainly that existing technology wind power utilization rate is low, and floor space is big, and generated output is little, problem such as damage easily during high wind.The utility model is made up of pneumatic blade, generator, wind-force rudder and supporting post; It is characterized in that supporting post (6) is provided with portable stanchion (5), supporting frame (4) and rudder (2); Connect two generators group (3) and wind-drive lower blade through supporting frame (4); Facing the wind to produce and go up the thrust rotation, and two groups of folding blades (1) that can open and close with the wind.Folding blade (1) laterally arranges with rudder (2); One group of folding blade (1) and generator set (3) are that mirror is to setting with another group folding blade (1) and generator set (3); Quantity of each group folding blade (1) is 3 to 5, and rudder (2), supporting frame (4) and portable stanchion (5) are for being fixedly connected, and portable stanchion (5) and supporting post (6) are flexible connection; By rudder (2) control portable stanchion (5) twisting, make folding blade (1) forward rotation down with the wind all the time.Folding blade (1) is made up of rachis (7), movable half vane A (8), movable half vane B (9), and movable half vane A (8), movable half vane B (9) are provided with the connection set (10) that flexibly connects with rachis (7) and restraint half vane A (8), movable half vane B (9) limit stoper (11) along rachis (7) opening angle.Connection set (10) is axle sleeve type, clamping type or the comings and goings Placement that is used with bearing.Movable half vane A (8), movable half vane B (9) serve as an axle folding with rachis (7), and slewing area is 0 to positive and negative 90 to spend, and is controlled by the closed buffering stop block (12) on the rachis (7) and opens buffering stop block (13).The shape of movable half vane A (8), movable half vane B (9), big I are identical, also can be different, movable half vane A (8), movable half vane B (9) can be simultaneously and rachis (7) combination use, also can make up use with rachis (7) separately.The windward side that movable half vane A (8), movable half vane B (9) constitute is plate shaped, spill, flute profile, spoon shape, leaf shape or other streamline shape.Principle is when the F wind direction the wind comes from, and is positioned at the folding blade (1) of bottom, and wind-receiving face is big, under the effect of wind-force, rotates from bottom to top, promptly presses the rotation of R sense of rotation, drives generator set (3) generating.Rudder (2) plays to adjust automatically direction, drives portable stanchion (5) and goes up rotation at supporting post (6), makes folding blade (1) be in the forward rotary state that facings the wind all the time.The utility model and existing technology are relatively; Usefulness is on a supporting post (6), to be provided with two groups of high-power generating folding blades (1) and generator set (3); Practice thrift a supporting post (6), owing to be vertically to rotate between folding blade (1) and the wind, supporting post (6) receives the generation technology of wind-force less than existing lateral rotation fan blade; So wind loading rating is strong, should not damage.Because folding blade (1) can be designed to far be wider than the blade of existing technology; So generated output also is improved, have two groups of power generating equipment output powers to double on the supporting post (6) than single group power generating equipment output powers in addition since folding blade (1) adopt the open-close type design; When effectively having reduced folding blade (1) and being positioned at top and facining the wind dorsad; Therefore upper blade, has increased generated energy to the negative work influence that lower blade produces.Owing to adopted the mode of lower blade acting; Make movable half vane A (8) on the folding blade (1), movable half vane B (9) when rotating with the wind; Folding smoothly under the double action of centrifugal force and wind-force; The phenomenon that two half vanes collide each other be can not produce, the reliability and the Security of blade folding in the using process guaranteed.More than the twice of the utility model greater than two same ratio existing technology power generating equipment output power summations, promptly the output power than the wind power plant of separate unit same size is big more than 4 times.
