Embodiment
As shown in Figure 1, the present invention includes casing supporting base assembly 1, vertical shaft assembly 2, blade assembly 3 and screw 4.
Casing supporting base assembly 1 is made up of combination bearing 102, bearing support 103, radial bearing 104 and bearing (ball) cover 105 that gearbox casing 101, circular hole are built-in with steel ball; Combination bearing 102 is installed in the gearbox casing 101; Bearing support 103 is installed in gearbox casing 101 tops; Inside is equipped with radial bearing 104 and bearing (ball) cover 105 is housed, and plays supports vertical axle assembly 2, bears the thrust load and the radial load that come from vertical shaft.
The vertical shaft assembly 2 pin 202 fixing transmission shafts 201 of serving as reasons connect to form with blade installation shaft 203; Be processed with keyway on the transmission shaft 201, in order to installation gear transferring power, but the other end mounting blades assembly 3 also can be connected with blade installation shaft 203; Blade installation shaft 203 is for each other can end to end quill, and is fixing by pin 202; Blade installation shaft 203 all can be in order to mounting blades assembly 3 with transmission shaft 201, and blade assembly 3 produces wind-force and drives blade installation shaft 203 rotations, through transmission shaft 201 outputting powers.
Blade assembly 3 is a wind-drive device, by torsion spring 301, and horizontal axis 302, stop screw 303, axle sleeve 304, bearing 305, bearing (ball) cover 306, adjusting screw 307, fastening screw trip bolt 308, link 309 is formed with vane plate 310; Torsion spring 301 is sleeved on the horizontal axis 302, the angle of relative swing between adjustment horizontal axis 302 and the axle sleeve 304, and then regulate rotation speed of fan; Horizontal axis 302 left ends pass vertical shaft 2 and fixing by screw 4, are with torsion spring 301 on it, and fixing by stop screw 303, right-hand member and bearing 305 inner rings are equipped, and bearing (ball) cover 306 is housed; Axle sleeve 304 left ends are processed into half-axile sleeve, have torsion spring 301 spacing in the bottom of vertical guide, and axle sleeve 304 endoporus and bearing 305 outer rings are equipped, and right-hand member links to each other with link 309, can be together around horizontal axis 302 rotations; Adjusting screw 307 is fixing with link 309 with axle sleeve 304, and the equalising torque of 310 pairs of horizontal axis 302 of adjusting vane plate; Fastening screw trip bolt 308 is fixed on vane plate 310 on the link 309; Link 309 plays connecting bushing 304 and vane plate 310.Horizontal axis 302 is not around rotational; Vane plate 310, link 309 and the axle sleeve 304 that connected together by adjusting screw 307 are around horizontal axis 302 swings; When vane plate 310 spacing by stop screw 303 when horizontal axis 302 is put to substantially horizontal by vertical, spacing by torsion spring 301 when in the other direction being rocked to the plumb position.
Vane plate 310, link 309 are connected with axle sleeve 304 among the present invention, can rotate (or swing) around horizontal axis 302 but need satisfy vane plate 310 together with axle sleeve 304 according to the design of size situation.
All part materials and size require to confirm by the output and the product technology of actual product among the present invention.
Can devote oneself to work after according to above-mentioned principle casing supporting base assembly 1, vertical shaft assembly 2 and 3 assemblings of blade assembly.Be that example is explained working procedure of the present invention with the wind energy conversion system that four groups of blades, every group two leaf are installed below:
At first, under calm situation, vane plate 310 is adjusted to the state at an inclination angle by adjusting screw 307.When wind is moving; The vane plate 310 of vertical shaft 2 both sides is under wind; Swing in the opposite direction around horizontal axis respectively; Spacing when the vane plate 310 of present dynasty Vertical direction swing is rocked to the vertical guide state by torsion spring 301, spacing by stop screw 303 when the vane plate 310 of substantially horizontal swing is rocked to level; At this moment, the suffered wind-force of the vane plate of vertical state 310 is much larger than the vane plate 310 suffered wind-force of level, and blade assembly 3 begins to rotate outputting power around vertical shaft 2; When wind speed strengthened, the elastic force that the vane plate 310 suffered wind-force of vertical state can overcome torsion spring 301 made vane plate 310 continue swing, no longer keeps the vertical state, has reduced wind-exposuring area, to reduce rotating speed, stabilized (steady-state) speed has been played certain effect.When wherein a vane plate 310 was vertical with wind speed direction, the suffered wind-force of blade was maximum, turned over 45 when spending, and just had a blade (adjacent blades) that maximum value is arranged again; In fact, every when 45 spend, just there is a vane plate 310 to reach maximum collection wind area, two adjacent blades before and after it also have certain collection wind area simultaneously, and each blade circulation is constantly worked like this, and wind energy conversion system then can ceaselessly rotate outputting power.
