Description
Technical field
What the present invention relates to is a kind of vertical axis aerogenerator, specifically is meant a kind of constant speed span type vertical axis aerogenerator.
Background technique
Wind-driven generator can be divided into two kinds of horizontal axis and vertical shaftes by the direction of running shaft.At present, horizontal axis wind-driven generator is widely used.Horizontal axis wind-driven generator manufacture and design more complicated, have following deficiency: 1) impeller take up space and floor space big; 2) blade of impeller wind-engaging inequality, particularly unsettled installation also will bear the huge positive pressure of wind, 3) the cost height, single-machine capacity is big more, and cost is high more.By contrast, vertical axis aerogenerator has a lot of advantages.But, the wind speed round of present vertical axis aerogenerator changes along with change of wind velocity, caused the unstability of generating, in order to overcome power generation stabilization, usually on wind-driven generator, be provided with a blade turning mechanism, make mechanism complicated, also consumed the energy of wind greatly, restricted applying of vertical axis aerogenerator.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, proposed a kind of novel constant speed span type vertical axis aerogenerator.This wind-power electricity generation function is regulated the blowing area of wind wheel by the variation of mechanism when wind speed changes, and change the height apart from ground, thereby keeps the wind wheel constant speed to rotate, and operates steadily, and it is little, simple in structure to start wind speed.
Technological scheme of the present invention is as follows: constant speed span type wind-driven generator is made up of wind wheel, pylon, oil hydraulic cylinder, hydraulic power system, gear-box, generator, braking system.
The rectilinear installation of wind-driven generator, wherein: braking system, generator, gear-box, hydraulic power system, oil hydraulic cylinder is installed in pylon inside successively.
Described wind mill wind wheel is made up of blade, quadrilateral connecting rod mechanism, pole, last steel cylinder, following steel cylinder, wherein: blade is connected with quadrilateral connecting rod mechanism, quadrilateral connecting rod mechanism is connected with last steel cylinder, pole is connected with following steel cylinder, wind wheel has six blades, six groups of blade shrouds are equally spaced around following steel cylinder, guarantee the stationarity of wind wheel running.
The described steel cylinder of going up is connected with bearing with pylon, can only be around axis rotation, and following steel cylinder is connected with pylon with linear bearing, can rotate around pylon, can do axial motion under the oil hydraulic cylinder effect again.
Described oil hydraulic cylinder places down steel cylinder inside, can promote down steel cylinder and move up and down.
During wind-driven generator work: when the input wind speed is big, oil hydraulic cylinder is initiatively withdrawn, steel cylinder is descended, driving pole moves downward, pole is inwardly moved quadrilateral connecting rod mechanism, thereby cause downward simultaneously, the inwardly motion of blade, the blowing area and the height off the ground of wind wheel diminish simultaneously, and the input wind energy tails off; On the contrary, when the input wind speed hour, oil hydraulic cylinder stretches out, make down the steel cylinder rising drive pole and move upward, pole makes quadrilateral connecting rod mechanism outwards move again, thereby causes wind wheel blade upwards and outwards to move simultaneously, the blowing area of wind wheel and height off the ground become greatly simultaneously, and the input wind energy increases.Initiatively extend and shrink by oil hydraulic cylinder, regulate the blowing area and the height off the ground of wind wheel, in the time of can guaranteeing the wind speed size variation, wind energy conversion system keeps constant speed to rotate preferably, thereby has guaranteed the stability of generating.
Wind powered generator system of the present invention adopts six groups of blades, and the adjusting by linkage mechanism changes the blowing area and the height off the ground of wind wheel, makes when the wind speed size variation, and wind wheel keeps constant speed to rotate.Native system is simple in structure, has advantages such as to start wind speed little, and noise interference is low.
