Embodiment

Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but do not limit the scope of the invention.

A kind of annular of embodiment of the invention sail type wind generator Structure of can inclining is as depicted in figs. 1 and 2, comprises that annular flat is layered on the track 3 on the scaoffold 13, and the plan view of said scaoffold 13 is as shown in Figure 3; Be arranged on generator unit 6 and sprocket wheel 10 on the said track 3, said generator unit 6 is connected with said sprocket wheel 10, and it is as shown in Figure 7 that it connects schematic representation; Be arranged on a plurality of chassis 2 on the said track 3, said chassis 2 is through connection set and 10 engagements of said sprocket wheel; Said chassis 2 is provided with tilting-type sail 4, and the lower end of said tilting-type sail 4 is equipped with counterweight 12, and the whole center of gravity that said counterweight 12 is used to regulate chassis 2 is under the turning axle of tilting-type sail 4; Said chassis 2 is provided with the flexible block 11 that is used to support said tilting-type sail 4, and the plan view of said chassis 2 and plan view are respectively like Fig. 4 and shown in Figure 5.In the present embodiment, because chassis 2 is circular layout on track 3, the tilting-type sail 4 of the side of doing work on the ring track 3 under the wind is in erectility under the cooperation of flexible block 11, to greatest extent absorbing wind energy; Do the tilting-type sail 4 meeting inclination several angles of negative work one side, play and let out the effect that wind reduces resistance, reduce the negative work effect.The pretightening force of flexible block 11 is F, and when wind-force during less than power F, the tilting-type sail 4 of doing positive work one side is in uprightly, to greatest extent absorbing wind energy.Wind-force is during greater than power F, and flexible block 11 is compressed, and the tilting-type sail 4 of doing positive work one side also can promote flexible block 11 and recede, and when the side tilting-type sail 4 that guarantees to do manual work was upright, it was stressed to reduce tilting-type sail 4.Thereby on ring track 3 wind direction center line both sides, form an energy difference, promote chassis 2 and do circulatory motion.

In the present embodiment, connect through hinged 8 head and the tail of elasticity between per two chassis; Said chassis 2 comprises the wheel that four arcs are arranged, wherein, three wheels are for rigidly fixing, and a wheel is that elastic compression is fixed.In the present embodiment, the bogie wheels arc arranges that schematic representation is as shown in Figure 9, and chassis 2 moves in a circle on track 3; For avoiding sliding friction chassis 2 wheel design is the arc arrangement, and then there is the problem of coplane in four wheels of chassis 2 if be designed to rigidity entirely; Therefore chassis 2 being designed to three wheels is what rigidly fix; Another is elastic compression wheel, all contacts steady when the maintenance dolly moves on ring track 3 with track with these four wheels that guarantee chassis 2.

The structure of the connection set of the embodiment of the invention is as shown in Figure 8; Said connection set comprises arc plate 5 and sleeve 14, and said arc plate 5 is parallel and middlely have the steel plate of a fixed gap to constitute by two, contains pin shaft hole on the said arc plate 5; Said sleeve 14 is fixed on the said arc plate 5 through bearing pin 9; When chassis 2 was done circulatory motion, said sleeve 14 and said sprocket wheel 10 engagement driving were converted into electric energy with the revolution kinetic energy of chassis 2 through generator unit 6.

Said tilting-type sail 4 comprises skeleton and covering, and said skeleton is processed by aluminum alloy, and said covering is processed by organic material, and said tilting-type sail 4 comprises the aerofoil profile end face with lift effect.Because the adjusting of counterweight 12, the whole center of gravity O that makes chassis 2 utilizes roly-poly principle under tilting-type sail 4 turning axlees, realizes that tilting-type sail 4 tilts with upright under wind automatically.The present invention's contrary wind side has tilting-type sail 4 designs of tumbler characteristic, adopts and lets out the wind principle against the wind, realizes energy difference in ring track 3 center line both sides, the realization wind-power electricity generation, and its tilting-type sail and counterweight roly-poly principle are as shown in Figure 6.

As shown in Figure 3; Maintenance channel 1 and maintenance stair 15 are installed on the said scaoffold 13; Said maintenance channel 1 is installed in said track 3 outsides, and said maintenance stair 15 are arranged between said maintenance channel 1 and the ground, and maintenance channel 1 is passages of workman's installation and maintenance with maintenance stair 15.The outside of said maintenance channel 1 is equipped with guardrail.

In embodiments of the present invention, major parameter is: footpath 100m in the ring track 3; Monomer chassis 2 length 4m, width 2.5m; 70 of chassis 2 quantity; Tilting-type sail 4 high 5m, the wide 2.5m in top, the wide 3.2m in bottom; Track 3 is 3m apart from ground, and height overall of the present invention is no more than 10m, belongs to the overhead system electricity generating device.

If neargale is a Limit of Wind Speed, blast is tabled look-up: w=18.28 * 10=182.8N/m ², S=LB=32 * 5=16m ², F=wS=1828 * 16=2925N,

$q=\frac{F}{l}=585N/m$

Mast is equivalent to the overhang that a linearity is all carried, and receives the linear wind-force that all carries and the resistance of block, wind-force arm l ₁Be 5.5m, resistance arm l ₂Be 0.5m, that is:

$M=\frac{1}{2}{{\mathrm{ql}}_1}^2=\frac{1}{2}\×585\×5.5=8900N\·m$

According to initial tension of spring F ₀L ₂=M gets F ₀=17800N.

Calculate according to intensity, the employing external diameter is that the steel strength of 120mm wall thickness 10mm will meet the demands.We adopt the beam of uniform strength here, help to strengthen the rigidity of mast.

Generated energy calculates:

Blast W ₀Unit be [KN/m ²], the unit of air density ρ is [Kg/m ³], the unit of wind speed V is [m/s].

Can know that according to Bernoulli's equation the dynamic pressure of wind is calculated as

Get number V=12m/s in the strong breeze speed,

Then: $W_0=\frac{1}{2}\&times;1.293\&times;{12}^2=0.093\mathrm{KN}/{\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="HDA0000153478150000021.png"\; state="\{\{state\}\}">m</figure-callout>}}^2=0.093\mathrm{KPa}$

The sail area of effectively doing manual work is calculated in programming

Can get S _∑=320m ²,

Acting on the power generation system effective power is: F _∑=W ₀* S _∑, i.e. F _∑=0.093 * 320=29.76KN

Torque and torsion and action radius concern T=F * R, if sprocket diameter is 1m, then R=0.5m

So torque T=29760 * 0.5=14880 (Nm) of sprocket wheel

Generator system efficiency eta=0.6, chassis speed is got V=6m/s

Chain wheel speed then $n=\frac{60\&times;\mathrm{<figure-callout\; id="2"\; label="V"\; filenames="HDA0000153478150000021.png"\; state="\{\{state\}\}">V</figure-callout>}}{2\&times;\mathrm{\&pi;}\&times;R}=\frac{60\&times;6}{2\&times;3.14\&times;0.5}=114.6r/\mathrm{Min}$

Generator system power $P=\frac{T\&CenterDot;n\&CenterDot;\mathrm{\&eta;}}{9550}\frac{14880\&times;144.6\&times;0.6}{9550}=107.14\mathrm{Kw}$

As if with the annual effective wind speed time being calculating in 4000 hours:

Then: N=pt=107.14 * 4000=4.29 * 10 ⁵Kwh

Annual generated energy is for can get generated output under the different wind speed, and its corresponding relation is as shown in table 1:
