The invention relates to a three-degree-of-freedom
manipulator for an automatic fire-fighting
robot of a
power station. The three-degree-of-freedom
manipulator for the automatic fire-fighting
robot of the
power station comprises a three-degree-of-freedom parallel mechanism and a fire-extinguishing device. The three-degree-of-freedom parallel mechanism is located under the fire-extinguishing device, and the upper end of the three-degree-of-freedom parallel mechanism is connected with the fire-extinguishing device. The three-degree-of-freedom
manipulator for the automatic fire-fighting
robot can be used for fire fighting and fire extinguishing when a fire happens to the
power station, the
automation degree is high, movement is stable and flexible during fire extinguishing, the fire-extinguishing spraying range is wide, the fire-extinguishing efficiency is high, the safety performance is high, and the problem that the risk of manual fire fighting and fire extinguishing for the power
station is high is solved; and since the three-degree-of-freedom parallel mechanism is of a 3-RPS parallel mechanism form, on the one hand, the adjustment of the
azimuth of the fire-extinguishing device is achieved, and all-directional fire extinguishing work at various postures can be achieved through the three-degree-of-freedom manipulator; and on the other hand, a shock
absorption effect on the fire-extinguishing device is achieved, the fire-extinguishing device can be in a horizontal
stable state all the time when traveling under the bumpy condition, and potential safety hazards, caused by excessive shaking, to stored fire extinguishers are prevented.
