Description
Technical field
Technical field of wind power generation is the utility model is related to, specifically, is related to a kind of wind power generation unit blade deicer.
Background technology
Wind turbines are more in the higher windy region of height above sea level, and the low temperature environment brought therewith is to blade or even whole blower fan
All bring acid test, it is single for blade, the blade caused by low temperature environment freezes, material and structural behaviour change,
The problems such as load changes is, it is necessary to have more excellent solution and finer design to consider.
Low temperature factor influences the design of blower fan at many aspects：The rising of atmospheric density is to blower fan under ice and frost and low temperature
Pneumatically there is more significant influence, and then influence the load and power output of blower fan.Low temperature can cause blade to adhere to larger quality
Ice sheet, so as to which the frequency of fan blade can be changed, and then change its dynamic response behavior.Meanwhile control system also can be by shadow
Ring.The aerodynamic configuration of blade is changed due to freezing, may shift to an earlier date or delay than expected design so as to result in blade stall.That
Configuration corresponding to the control of electronic or hydraulic vane change should also change therewith.Blade, which freezes, can cause the detection signal system of blower fan to be sent out
Raw failure is so as to feedback error signal.Limit low temperature needs to change the material of fan section part, such as conventional steel can become
It is crisp.
Hinterland particularly mountain area, large scale blower fan can all be influenceed in operation and shutdown by ice formation issues.To the greatest extent
Pipe early stage considers the blower fan of ice formation issues, is mounted with the heating deicing system with special sensor and corresponding auxiliary facility during trial operation
System, have accumulated certain experience.But in the market also occurs without ripe and standardization low temperature blower fan so far.
In view of this, it is special to propose the utility model.
Utility model content
The utility model aims to provide a kind of wind power generation unit blade deicer, blade surface set can irrigate gas or
The sealing elastomeric membrane of liquid, the purpose for the ice sheet for removing blade surface is realized using the deformation of elastic membrane.
To achieve these goals, the utility model specifically adopts the following technical scheme that：
A kind of wind power generation unit blade deicer, blade 1 from blade root 14 along length of blade direction by extending to leaf tip
15 housing is formed, including fluoran stream surface 12, lee side 13 and the blade inlet edge 11 set windward, the fluoran stream surface 12 and/or the back of the body
