Elaborate embodiments of the invention and working principle with reference to accompanying drawing.
Accompanying drawing 1 expression general structure.(1) be two fins, the fin number is one or more.Fin is contained in the end of whippletree (2), can be around the axle small angle of aa beat (＜30 °) that hangs down.Wing tip (7) can temporarily be thrown off when keeping away strong wind automatically in when work and fin pinning.Whippletree (2) connects the upper end of vertical shaft (3).Vertical shaft (3) lower end connects with universal joint (6) and driving mechanism (5), and its base is fixed in ground, and hawser (4) pulling on ground is fixed in by supporting sleeve (35) in the upper end with an end.Vertical shaft (3) is made with steel pipe, can load onto the supporting sleeve (28) that several tape spools hold on vertical shaft (3) steel pipe as required, holds with steel cable (4), to guarantee its rigidity.
Below more in conjunction with the accompanying drawings 2, narrate its working principle.See wind energy conversion system from top to bottom, O is the axis of rotation of vertical shaft (3), and ω is the wind energy conversion system rotating speed, and r is the turning radius of wind energy conversion system, and W is a wind speed, and p is the fulcrum of two fins, is exactly that fin beat center line aa(sees accompanying drawing 1) pass 2 points of the scraps of paper.When fin forwarded windward to, because the fulcrum P of fin swing axis, before Pneumatic pressure center C P, the outside beat of fin leading edge was kept off at the δ angle by a, at this moment, relative velocity is V, gets angle of attack α, therefore produces lift L, resistance D makes a concerted effort to be R that the thrust of then effectively rotating wind energy conversion system is F.And fin is when forwarding leeward to, and wind speed has dropped to W ', and the transposition of the relative fin of wind direction, at this moment, the inside beat of fin leading edge at δ ' angle, is correspondingly produced thrust F ' by a ' retaining again.Deflection angle δ, δ ' suitably are set, can obtain angle α, α ' increase effective push F, the F ' of optimum range.So Wing swinging type vertical shaft wind motor starting that Here it is easily, the reason that efficient is high.Deflection angle δ and δ ' control (seeing accompanying drawing 4) with simple centrifugal mechanism.When proper functioning, can control rotating speed and be no more than limit.When wind speed reached hazard level, wing tip was thrown off automatically, and the wind energy conversion system stall sees accompanying drawing 3 for details.
Accompanying drawing 3 shows the action principle of wing tip, and when its left side illustrated proper functioning, wing tip (7) and fin (1) pinned, and the two is in aggregates, and in last joint explanation, resultant thrust F promotes wind energy conversion system and rotates action principle at this moment.When wind speed increased to hazard level, wing tip (7) was thrown off automatically, and action principle is at this moment seen right figure.The fulcrum of wing tip (7) is at P, Pneumatic pressure center c, the p ' of wing tip (7), and before fulcrum, when wind speed was excessive, the aerodynamic force that is produced was thrown off wing tip (7) automatically, deflects into position shown in the right figure, unlocking mechanism such as accompanying drawing 5.At this moment fin (1) useful area reduces, so lift is reduced to L by L
1, resistance is reduced to D by D
1, the effective push that is produced is reduced to F by F
1, at this moment the angle of attack of wing tip (7) is α ", near 90 °, so its lift is approaching zero, but the negative thrust that resistance D " very big, resistance D " produces is F
2, direction is opposite with F.As long as choose enough wing tip areas, just can make the negative thrust F of wing tip
2Thrust F greater than fin
1Thereby, wind energy conversion system is slowed down, up to stall.
Fig. 4 is the beat and the speed limiting mechanism schematic representation of fin.
The left side is the schematic representation of fin among the figure.It has forward and backward spar and some ribs as framework, and plain cotton fabric is coated with dope and paint.(47) and (46) are forward and backward spars among the figure.(45) be rib.The right of figure is whippletree end, beat and the speed limiting mechanism of having taken apart.(8) are the whippletree end among the figure, and there are upper and lower two bearing holes (20) its outer end.Whippletree is hollow, and its inside has slidably has a slide block (19) of V-notch (44), holds with spring (21).Spring (21) is fixed in the whippletree (8).Bearing hole (20) is inserted with a minor axis (16).Minor axis passes two center holes (42) of beat (14) simultaneously, makes the beat (14) can be at the whippletree end around optio binormal deflection.The preceding pin (43) that is equipped with of the center hole (42) of beat (14) passes the V-notch (44) of slide block (19).During beat (14) left and right sides deflection, pin (43) is subjected to the restriction of V-notch (44), can only small angle of beat.Beat (14) is fixed on spar (46), (47) middle part, so fin can be with beat (14) around small angle of optio binormal deflection.When wind energy conversion system rotated, slide block (19) was subjected to centrifugal action outwards sliding, but was subjected to the pulling force of spring (21) and stops at certain position.Therefore the wind energy conversion system rotating speed is depended in the position of slide block (19), and rotating speed is big, and centrifugal force is big, and slide block is more to overhanging.At this moment the shelves V-notch (44) of living lever (43) narrows down, and deflection angle is diminished.Therefore the deflection angle of fin also diminishes, and the angle of attack that this changes fin reduces pneumatic effectiveness, and wind energy conversion system is speedup more not just.Suitably select the angle of opening (44) and the rigidity of spring (21) etc., can make wind energy conversion system when wind speed increases, keep constant speed substantially, can not exceed the speed limit.
Accompanying drawing 6 is bamboo wood rib structure figure.It is light more good more that the wind energy conversion system fin requires, because of it is the structure of decision complete machine, and weight, a key factor of cost and benefit.The thirties, wooden aircraft wing added the structure of plain cotton fabric with wood truss, and is light and firmly, can use for reference.Bamboo wood is light, and intensity is good, and is easy to process, treated can never degenerating all the year round, and china natural resources is abundant, to stressed not too big member, is desirable truss material.But in truss fabrication, the connection of bamboo wood end is very difficult, does not adopt the bamboo wood truss structure so see wind machine oar leaf always.Joining method of the present invention has solved this problem.Be a rib shown in the figure, the spar structure is identical.Truss is formed by bamboo wood (25) connection.Bamboo wood (25) terminal jagged (12) fastens with tinsel (26), tightens also available glue or additive method fixing metal sheet (26) with line (27).This bond strength, adds plain cotton fabric or paper and adds the fin that coating is made by rib and the spar that bamboo truss is made near bamboo wood intensity, and is in light weight, less than 1/40th of solid aluminum fin weight.
Accompanying drawing 7 is a whippletree vertical shaft structural drawing, and left figure is an overall diagram, and whippletree (2) is one whole steel pipe, connects with pin (30) with the top of vertical shaft (3) in central authorities, sees right two figure for details.A pellet (29) is filled at the center of whippletree (2).The minor axis on vertical shaft top (31) puts in the center of pellet (29) and whippletree (2), and with pin (30) pinning, the effect of pellet (29) is a moment of flexure of eliminating pin (30), makes it be subjected to shearing.Minor axis (31) is by an annular bearing with rolling contact (33) and an axial antifriction bearing (32) supporting.Two bearings are contained in the wirerope cover (35).Minor axis (31) pins vertical shaft (3) with pin.Seeing left image.
Vertical shaft be rotating shaft be again support.Different with former patent, the present invention makes vertical shaft with steelframe, but adopts steel pipe to make vertical shaft, makes total simple, and is in light weight.The vertical shaft top puts in the wirerope cover (35), with three wireropes (4) wirerope cover (35) is tied on the wirerope Chinese toon of ground.The steel pipe vertical shaft both can adopt overall structure, also can adopt segmental structure, when vertical shaft is higher, adopted segmental structure more suitable.Vertical shaft is high more, and wind speed is big more, and is favourable more to wind energy conversion system, but vertical shaft is high more, and then the vertical shaft steel pipe is elongated, is easy to bend.In order to guarantee the structure stability of very high vertical shaft, the available supporting sleeve (28) that has only radial bearing, being contained in the vertical shaft waist also holds with hawser, when adopting the vertical shaft of segmental structure, each steel pipe that connects vertical shaft with custom-designed shaft coupling (34), shaft coupling (34) is a sleeve pipe, with pin and vertical shaft (3) pinning.Segmentation vertical shaft steel pipe length between two shaft couplings is unsuitable long, otherwise is not easy to transportation.In addition, for make belt pulley or other air horsepower output mechanisms not the reason vertical shaft rock and wave, different with former patent, universal joint (6) is housed in the vertical shaft lower end, avoided rocking of driving mechanism base like this.This universal joint (6) can also make vertical shaft fall on the ground together with fin, the lifting and the maintenance of big convenience wind energy conversion system.Removed the requirement of axis between the two of vertical shaft and transmission shaft simultaneously.The driving mechanism fixed bottom boundary has also made things convenient for the connection of ground machine.
Accompanying drawing 8 shows the combination of two wind energy conversion systems, the assembling of right illustrated parts.Schematic representation when left side figure is the wind energy conversion system rotation of assembling back, (50) are a plane trigonometry frame among the figure, set of gears case and generator component (49) are contained in the plane trigonometry frame (50), a wind energy conversion system (48) turns around with the following universal joint of gear-box (49) and is connected with the universal joint above the universal joint connection gear case (49), another same wind energy conversion system (51).Each tightens two wind energy conversion systems with three short wireropes and plane tripod (50), and the power of Zu He wind-driven generator is two times of a typhoon power generator like this.
Accompanying drawing 9 is the combination of high-power wind-driven generator.Have six covers combined wind power machine (53) as shown in Figure 8 to be installed in six roots of sensation boom (52) end among the figure, the inner of per three booms is connected on the mast (55) together, and six roots of sensation boom forms two layers of identical structure, is bundled into integral body with 15 wireropes.In addition, the end of uppermost three booms (52) is tightened with the top of mast, also had six roots of sensation wirerope (54) that the end and the ground of following boom are tied with three wireropes.This mast that fastens with wirerope.The boom framework is light and economical than the angle bar pylon.Be not less than seven times of its diameter as the spacing of little wind energy conversion system, the power of the little wind energy conversion system of lee face seldom is subjected to the influence of the little wind energy conversion system in windward side, and this framework is also very ventilative, thus by the power of the wind energy conversion system of 12 little wind energy conversion systems combinations near 12 times.As long as increase the boom level again, can also increase the power of combined wind power machine continuously.Framework high because mast and wirerope ground take up an area of very little and ventilative, to the farming on ground, herd operation and low Influence on Architecture is very little.Be combined into the largest benefit of high-power wind-driven generator by many single small-power wind energy conversion systems, be to produce same single small-power wind energy conversion system in a large number.The manufacture cost of wind energy conversion system is significantly reduced.
Accompanying drawing 10 is the combination of another kind of high-power wind mill, and left side figure is the pylon structure schematic representation, and the summit that pylon is made column and many level triangle steel pipe frames (57) with 3 steel pipes (56) connects, and forms the triangle pylon that is divided into multilayer.Tighten with wirerope (58) on each summit of triangle steel pipe support (57).A little wind energy conversion system is adorned in the centre of each layer, (be clear wash rice meter, only draw the vertical shaft (59) of a little wind energy conversion system among the right figure).The pylon interlayer is many more, and the little wind energy conversion system of dress is many more, and power is also big more.Right figure is little wind energy conversion system scheme of installation.Different with aforementioned little wind energy conversion system, its whippletree (60) is fixed on the central authorities of vertical shaft (59).Vertical shaft (59) two ends up and down all connects universal joint (61).Universal joint (61) connects minor axis (63) minor axis (63) and passes rolling bearing (62), and rolling bearing (62) is contained in the central authorities of triangle steel pipe support (57).In order to reduce or remit the moment of flexure that vertical shaft (59) center causes because of lift, the summit of vertical shaft (59) and the outer end of whippletree (60) are held with four wireropes (64).Seeing left image, the pylon bottom is higher, and the vertical shaft of bottom central authorities (65) is also longer, and this vertical shaft also uses the driving mechanism (66) on universal joint (61) and ground to connect, and can drive generator or other machinery equipment.The wind energy conversion system on upper strata be vertical shaft by following each layer with power concentration to the driving mechanism (66) on ground.Driving mechanism and generator etc. are the advantages of this pylon all on ground.More powerful driving mechanism on ground can directly drive the agricultural machinery on ground or water pump etc., has exempted generator and motor, reduce investment outlay, and also be an advantage.This pylon can successively be assembled, and does not need to start crane, and convenient backland assembling also is an advantage.
