The invention relates to an icing detector based on grating fiber deformation. The detector comprises an icing rod, and a plurality of periodically arranged ice crystal collecting holes are formed inthe icing rod in the axial direction of the icing rod; the ice crystal collecting holes penetrate from the windward side of the freezing rod to the leeward side, windward nets are arranged at the ends, located on the windward side, of the ice crystal collecting holes, leeward nets are arranged at the other ends, located on the leeward side, of the ice crystal collecting holes, elastic supporting columns are further arranged between the windward nets and the leeward nets, and grating optical fibers are arranged on the elastic supporting columns in the axial direction. The invention discloses anicing detector based on grating fiber deformation, the windward net and the leeward net are arranged in an ice crystal collecting holes, the grating optical fibers are arranged between the windward net and the leeward net, when ice crystals are collected by the ice crystal collecting holes, the ice crystals extrude the windward net, the windward net moves to extrude the grating optical fibers, sothat the resonant wavelength of the grating optical fibers is changed, and the icing state can be detected by detecting the change of the resonant wavelengths of the grating optical fibers.

    本发明涉及一种基于光栅光纤形变的结冰探测器,包括结冰杆,结冰杆沿其轴向设置有多个周期排列的冰晶收集孔,冰晶收集孔由结冰杆的迎风面贯穿至背风面,冰晶收集孔位于迎风面的一端设置有迎风网,冰晶收集孔位于背风面的另一端设置有背风网,迎风网与背风网之间还设置有弹性支柱,弹性支柱沿其轴向设置有光栅光纤;该基于光栅光纤形变的结冰探测器,通过在冰晶收集孔内设置迎风网和背风网,在迎风网和背风网之间设置光栅光纤,当冰晶收集孔收集到冰晶的时候,冰晶会挤压迎风网,迎风网发生位移挤压光栅光纤,从而导致光栅光纤的谐振波长发生改变,通过检测光栅光纤的谐振波长的变化,就可以检测到结冰的状态。
