Abstract
The present invention relates to one kind of air filled blade for wind driven generator. The air filled blade consists of one casing filled with high pressure air and is one powerful rigid capable of resisting strong wind destruction. The present invention makes the wind driven generator possess high wind energy efficiency, easy manufacture, convenient installation and transportation and low cost.
Description
What technical field patent of the present invention related to is a kind of power-driven generator leaf of inflation.
The background technique fan blade is the vitals of wind-driven generator, and it is the primary device that obtains wind energy straight and determine fan efficiency.Its cost accounts for the 20%-30% of whole blower fan total cost.Most in the world at present power-driven generator leafs adopt composite material, its structure adopts D, O and C type beam, as framework, outer then composite panel, inner interlayer filling timber or the plastic or other material of covering, because timber is easy to make moist, rotten rotting, its processing cost is also high, and these materials increase leaf weight and cost undoubtedly, increase the wind wheel rotary inertia, be unfavorable for brake and startup, and take wind energy efficiency, because the material that uses all is a rigid material, the vibration ability that turbulent flow produces between Shun is relatively poor for resisting, the antifatigue degree is low, because fan blade requires height to surface flatness, body is long in addition, bring great difficulty to transportation, increase bigger cost of transportation.
The purpose of summary of the invention patent of the present invention is to overcome above-mentioned defective, and a kind of power-driven generator leaf of inflation is provided.For reaching above-mentioned purpose, the present invention adopts following scheme, adopts the high strength cord, is coated with rubber, through the uniform temperature sulfuration, suppresses the typing of its shape of leaf tire of the inner hollow that forms at high pressure and determines by the length of middle two wall connecting tendons in mould.Through being loaded on the wheel hub with sealing to cooperate.Sealing corresponding each hollow chamber all has the pipe fitting that adapts to inflation pressure to pick out, and joins with the solenoid valve that adapts to inflation pressure, and solenoid valve end in addition is attempted by on the pipe, and the pipe outlet is drawn, with as the inflation suction tude.
Supported flange dish, leaf tire, sealing with wheel hub and be pressed together with several bolts, because the leaf tire is enclosed within and seals, and be taper fit, just can keep sealing no longer to leak gas after compressing for this reason.Fill the gas of certain pressure of requirement when the leaf tire after, leaf tire and cavity pressure air be common to form a rigid body blade of resisting external force, its intensity:
δ＝∑Sh·ρ+δ
K·S
K……(1)
δ: blade strength, ∑ Sh: the stressed place of leaf tire cavity cross section sum, ρ: chamber inner air pressure, δ
K: the leaf tire strength of materials, S
K: the sectional area at the stressed place of leaf tire material.
The intensity of blade and leaf tire inner air pressure, blade maximum weighted cross section and leaf tire selected materials are relevant
The maximal destruction power that blade is subjected to is by F
b=1/2 ρ CrSV
2(2) determine
F
b: maximal destruction power; ρ: air density; Be air pressure, the function of temperature and temperature.
ρ＝1.276/1+0.00366t×(ρ
x-0.378e)/1000……(3)
ρ
x: the air pressure at blower fan place, t=temperature, e: water vapor pressure, Cr: pneumatic coefficient, S: fan blade generally is averaged the product of chord length and fan blade length L, V for the area of contour of plane of rotation: the maximal destruction wind speed.
Maximal destruction power is different with the location according to power of fan, can not impose unanimity, have nothing in common with each other both at home and abroad, selecting the 70/s wind speed is design considerations, also selecting the 60m/s wind speed is foundation, as long as δ＞Fb ... (4) this impeller of blower just has the ability of resisting selected collapsing force.
This scheme has increased the ability that ∑ Sh ρ resists external force significantly than prior art, and its blade materials can correspondingly reduce for this reason.Its another advantage is when manufacturing can to slow down the impact shock that turbulent flow caused between Shun at therebetween one deck rubber.
The fan blade of making by this programme greatly facilitates transportation, need not consider to bump brokenly the surface, can be coated with after fan blade is installed and inflated with epoxy resin paint to improve smoothness and to prevent ultraviolet ray ageing and moisture proof effect again.
This programme does not consider that blade tip flow spoiler and change slurry are apart from system, and its brake mainly reaches the flow spoiler braking action by discharging the interior air of the horizontal tail of blade (referring to the cross-section and wind outlet of blade) end place cavity.
Do not establish to become and starch apart from system, its generator power is regulated, and takes other scheme.With in another patent of invention case in explanation.Take a long view, if power of fan can separate leaf tire transversal centerline more greatly again, leaf tire cavity number will double so, increase multiway valve and air pump again, just reach and to carry out the change of certain limit to profile front end portion and rear portion camber at any time, adapting to change of wind velocity, and make fan operation in preferable power factor scope, to obtain bigger power output.This conciliation may not reach the effect that becomes the slurry distance.But it makes things convenient for manyly than the conciliation that becomes the slurry distance.Only need switch valve, open pump and just can realize.
Description of drawings Fig. 1, blade A-A sectional view, Fig. 2, blade cooperates erection drawing with wheel hub, Fig. 3, blade view.
Concrete enforcement as shown in the figure: 1, leaf tire, 2, seal, 3, the supported flange dish, 4, firm bolt, 5, solenoid valve, 6, tracheae, 7, wheel hub, 8, leaf tire inner chamber, 9, lightning-arrest part, 10, pressure transducer, 11, pneumatic tube.
Supported flange 3 is enclosed within on the footing of leaf tire 1, and the two sides is pressed leaf tire 1,1 and is enclosed within and seals on 2, place on the wheel hub 7, pass wheel hub 7, seal 2 by bolt 4, leaf tire 1 enters in the supported flange 3, because the firm effect of each bolt, 1 and 2 contact position is tightly forced together, can guarantee no longer slack gas leakage body, and guarantee the complete gas of independently depositing of each cavity, solenoid valve 5 inserts, from 2 pipes of drawing 12, the other end is connected on the pipe 6, and several solenoid valves air inlets simultaneously or open simultaneously also can separate air inlet.At ring leaf tire two ends lightening conductor 9 is set; so that thunder and lightning is introduced pylon to be entered underground; before wind-driven generator starts; should inflate earlier, its gas pressure should satisfy the design strength requirement, because air expands with heat and contract with cold; can provide information at any time it to be replenished or venting according to pressure transducer; bleed off horizontal afterbody air chamber gas separately, can play the damping plate effect, wind wheel speed is descended rapidly reach the purpose of shutdown.
