The every rubber strip is hanging for one end and the affixed other end in shell side of the anti-icing noise reduction wind electricity blade, often
Root is whole and shell side is in 25 ~ 35 ° of angles, and every two adjacent rubber strip inclined directions are on the contrary, so as in rubber strip
Portion, adjacent two rubber strip cross-contacts but not affixed；Diameter per two adjacent rubber strips differs, wherein one is
2 times of other one, the rubber strip for setting of gathering integrally are divided into end rubber strip and tip rubber strip, and the end rubber strip is close
Cloth degree is gathered 1.5 ~ 2 times of degree for tip rubber strip.
The rubber strip count in parts by weight containing：Vinylsiloxane rubber：62 ~ 69 parts, butyl rubber：1 ~ 3 part, hard charcoal
It is black：16~23 parts, zinc oxide：1 ~ 2 part, calcium sulfate：0.5 ~ 1.1 part, hydroxy silicon oil：2~3 parts.
Preferably, the diameter per two adjacent rubber strips differs, it is whole to incline to anti-icing noise reduction wind electricity blade tip
The diameter of oblique one is 1.8 ~ 2.3 times to a piece diameter of sloped-end（Optimal is 2 times）.
Preferably, being additionally provided with temperature detection part inside the heat conducting pipe, detected when temperature detection part
After threshold value of the temperature value less than setting, start power supply part and power to heating wire.
Preferably, the organic acid is at least one of sebacic acid, isononanoic acid.
Preferably, the nitrogenous protection auxiliary agent is hexamethylenetetramine and/or 4-methylimidazole.
Preferably, the antifoaming agent is dimethyl silicone polymer.
Preferably, the antifoaming agent is polyoxypropylene ethylene oxide glycerin ether.
Preferably, the length of the lower end heat conducting pipe is the upper end heat conducting pipe and the tip heat conducting pipe overall length

Effect of the invention is that：
1, by setting conductive fluid and heating wire in heat conducting pipe, by electric-heating-wire-heating conductive fluid, and the specific heat phase of conductive fluid
To larger, a large amount of heat can be renewed, therefore blade is transferred heat to by conductive fluid again, temperature can be reached and transmit effect
The effect that rate is higher and the retention time is longer.
It is set by the arrangement to heat conducting pipe so that conductive fluid Temperature Distribution in heat conducting pipe is substantially equal
It is even.Since wind electricity blade is to want rotary work, when rotation, due to centrifugal force, conductive fluid will be to outside（Blade point
Portion）It is mobile, and for the influence of the factors to heat conducting pipe such as exclude to expand with heat and contract with cold, complete 100% it can't be full of heat conduction in heat conducting pipe
Liquid, therefore the conductive fluid meeting phase tip after heating is concentrated, so as to cause tip temperature and end region temperature uneven, so as to not only can
The waste of heat is caused, can also cause portion that can form icing when serious.Therefore by by heat conducting pipe lower end
Position is set as snakelike, so as to which when blade rotates, the portion tangent with rotation direction can be in part in snakelike
It forms liquid to disconnect, so as to retain fluid within end so that the temperature of conductive fluid is substantially uniformly distributed.When blade temporarily stops
After rotation stop is moved, partly flow to the conductive fluid of tip and can flow back into heat conducting pipe again and be uniformly distributed.By by the heat conduction of serpentine portion
The length of pipe is set longer（It is the summation of other length of tube）So that it is maximum in the conductive fluid total amount of the section store, so as to
Tip conductive fluid proportion shared in total amount is further reduced, further such that conductive fluid temperature in blade rotation process is equal
Even distribution.（The heat conducting pipe of blade interior can not be integrally both configured to it is snakelike because if doing so since conductive fluid has
Weight can cause the rotation of blade to be affected, while also blade interior stress distribution can be produced bigger effect, so as to
It can cause the shortening of leaf longevity）.
2, by being provided with rubber strip and by the specific setting to rubber strip in blade exterior so that while noise reduction
So that blade surface generates heat, reduce the generation of icing phenomenon.
It realizes that the noise reduction in blade rotation process is existing known technology in the densely covered rubber strip of blade surface setting, grinds
Study carefully how specifically being absorbed in for personnel to set every rubber strip to reach maximized noise reduction, but the inventors discovered that, if
Two adjacent rubber strips are arranged in a crossed manner, this two rubber strips can be collided mutually in blade rotation process, and this collision
Frictional heat can be generated, so as to which these rubber strips are while noise reduction is realized, can also be reached in blade by the setting of ad hoc fashion
Contribute the effect of heat in surface.By setting adjacent two rubber strips one thick one thin, and the two diameter proportion is set, is made
It obtains in blade rotation process, thinner rubber strip chattering frequency is higher（Wind-force is blown deformation, then due to rubber
Characteristic and spring back）, so as to higher with the collision frequency of a thicker rubber strip, and a thicker rubber strip chattering frequency is relatively
It is low, the problem of being shaken in the same direction so as to avoid two rubber strips and collision frequency is caused to reduce, so as to generate opposite rub
The heat is simultaneously transmitted on wind electricity blade surface by chafing according to the principle that even heat conducts.So as to be realized while noise reduction
Noise-reducing components generate the purpose of heats, reach more preferably deicing effect.
3, exist in heat conducting pipe since the conductive fluid needs in heat conducting pipe are long-term, for the ingredient of conductive fluid
It needs to adapt to the specific structure, by being improved its constituent content, appropriate reduces the content of water wherein, simultaneously
Temperature according to residing for blade and other components are changed so that the conductive fluid more adapts to the specific ring of the present invention
Border.
Pass through the improvement to rubber strip material so that the performance of its heat transfer is improved（Conventional reducing noise rubber item is simultaneously
The performance of heat transfer is not needed to, therefore is had not focused on to the improved motivation in this direction）, especially white carbon and calcium sulfate contain
The restriction of amount coordinates the incorporation of butyl rubber so that its heat-conductive characteristic gets a promotion.
