As the exploitation and unmanned plane during flying of low wind speed area wind field such as declare and supervise at the implementation of measures, the deicing capability of unmanned plane and remove
Ice efficiency is not also high, and the expense of deicing is also higher.
Blade heating deicing mode is to lay heating film or heater strip on leaflet inner faces in the vane manufacturing stage, and
Installation heating control apparatus, this mode need just to need to install, and due in leaf in the blade production phase in wheel hub or cabin
Laying heating film or heater strip etc. inside piece, the problems such as needing to consider temperature control and lightning protection, it is also necessary to extra consumption unit
A part of electric energy reduces the power generation performance of unit, while the blade of every unit is required for being pre-installed in advance, and cost also compares
It is higher.
Ultrasonic wave deicing mode generates vibration using ul-trasonic irradiation in blade surface, and the ice sheet of blade surface is shatter simultaneously
Come off to play the role of anti-deicing, generally comprise icing monitoring unit, ultrasonic wave control device, supersonic signal generator and
The devices such as amplifier, the Nomenclature Composition and Structure of Complexes is more complicated, and cost is also higher.
In summary, artificial deicing and unmanned plane deicing efficiency are low and of high cost.Deicing and ultrasonic wave deicing are heated, is needed
Heating unit or supersonic generator etc. are fixed in fan blade, increases the weight of fan blade, heavy blade exists
After installation can fan parts of bearings bring huge heavy burden pressure, increased weight can also in wind turbine operating lifting means
Fatigue strength shortens leaf longevity.Also it is unfavorable for the stability of anti-icing and de-icing device.Therefore, design one kind does not increase leaf weight
Anti-icing and deicing system, be those skilled in the art hot research problem.
