The invention provides a fire-fighting unmanned aerial vehicle lens cleaning device capable of preventing smoking based on magnetic force change. The fire-fighting unmanned aerial vehicle lens cleaning device comprises a lens barrel body, wherein a sliding groove is formed in the inner part of the lens barrel body and is positioned on the outer side of a protective lens; a sliding seat is movablyconnected to the inner part of the sliding groove and is positioned above a storage seat; cleaning cotton is arranged between the sliding seat and the storage seat; a heat conducting rod extending into an air cavity is fixedly inserted into the front surface of the lens barrel body; uniformly distributed conducting strips are fixedly arranged on the left side of the sliding groove; and electromagnets corresponding to the conducting strips are fixedly arranged at the bottom of the sliding groove. The closer an unmanned aerial vehicle is to a fire area, the higher the air temperature is, heat istransmitted into the air cavity through the heat conducting rod, the inner pressure of the air cavity is increased to a certain degree and then ejects a valve, the air flow pushes the sliding seat torotate along the sliding groove, power is provided through the conducting strips and the electromagnets, the sliding seat pulls the cleaning cotton to wipe and clean the protective lens, and the problem that the protective lens of a camera on the unmanned aerial vehicle is smoked and blurred is avoided.
本发明提供一种基于磁力变化防止烟熏的消防无人机镜头清洁装置,包括镜筒主体,镜筒主体的内部且位于防护镜片的外侧设置有滑槽,滑槽的内部且位于收纳座的上方活动连接有滑座,滑座与收纳座之间安装有清洁棉,镜筒主体的正面固定插接有延伸至气腔内部的导热杆,滑槽的左侧固定安装有均匀分布的导电片,滑槽的槽底固定安装有与导电片对应的电磁铁。无人机越靠近火灾区域,空气温度越高,通过导热杆将热量传输到气腔内,气腔的内压升高到一定程度后顶开阀门,气流推动滑座沿着滑槽转动,通过导电片和电磁铁提供动力,滑座拉动清洁棉对防护镜片进行擦拭清理,避免了无人机上摄像机的防护镜片被烟熏模糊的问题。
