The invention belongs to the field of pantograph maintenance, and particularly relates to a low-wind-resistance protection device for preventing a pantograph from icing, which comprises two fixed spheres, a fixing groove is formed between the two fixed spheres, and a fixing mechanism for connecting the two fixed spheres is arranged outside the fixed spheres. A conversion cavity is formed in each fixed sphere, an energy conversion mechanism is arranged in the conversion cavity, a fan is arranged in each fixed sphere, one side of the fan is communicated with the outside, the other side of the fan is communicated with a heating cavity, an eddy current mechanism is arranged in the heating cavity, and a temperature measuring mechanism for controlling the eddy current mechanism to work is arranged in each fixed sphere. According to the device, the vibration energy of the pantograph can be absorbed and converted into electric energy in a normal state, then the pantograph is heated by the electric energy in a resistance heating mode and an eddy current heating mode under the low-temperature condition, and the situation that the pantograph is frozen is avoided.

    本发明属于受电弓维护领域,尤其是涉及一种防止受电弓结冰的低风阻防护装置,包括固定球体,所述固定球体设有两个,且所述固定球体之间设有固定槽,所述固定球体外部设有将两个固定球体相连接的固定机构,所述固定球体内设有转换腔,所述转换腔内设有换能机构,所述固定球体内设有风机,所述风机一侧与外界连通设置,所述风机另一侧连通有加热腔,所述加热腔内设有涡流机构,所述固定球体内设有控制涡流机构工作的测温机构。本发明中装置能够通过常态下吸收受电弓的振动能量转换为电能,然后在低温情况下将会电能通过电阻加热以及涡流加热的方式共同使得受电弓升温,避免受电弓出现结冰的情况。
