The invention discloses a double safety protection device for a fire extinguishing unmanned helicopter with a high-altitude slow descending function. The double safety protection device comprises an unmanned aerial vehicle body, a slow descending base and a supporting plate; the slow descending base is connected with the bottom of the supporting plate through a plurality of damping shock absorbers which are symmetrically arranged, and the top of the slow descending base is fixedly connected with two stand columns which are symmetrically arranged; the two stand columns are rotationally connected through a rotating rod, the outer portion of the rotating rod is fixedly sleeved with a friction wheel, and the bottom of the supporting plate is fixedly connected with a plurality of friction plates corresponding to the friction wheel; four supports arranged in a rectangular shape are fixedly connected to the bottom of the unmanned aerial vehicle body, connecting plates are fixedly connected to the bottoms of the four supports, supporting legs are arranged below the connecting plates, and two sleeves symmetrically arranged are fixedly connected to the tops of the supporting legs. The double safety protection device is simple in structure and convenient to operate, a fire extinguishing mechanism is convenient to disassemble and assemble, the overall damping and buffering performance is high, and the service life is greatly prolonged.
