WIPO Patent Application WO/2022/000525
Kind Code:
A1
Abstract:
Disclosed is a fire-fighting unmanned aerial vehicle cable traction device, comprising a winding device (20) and a throwing device (10). The winding device (20) comprises a winding wheel main shaft (23) and winding wheel wire blocking plates (24), wherein two ends of the winding wheel main shaft (23) are rotatably installed on two winding wheel wire blocking plates (24), the two winding wheel wire blocking plates (24) are respectively connected to winding wheel fixing plates (21), and the winding wheel fixing plates (21) are connected to an unmanned aerial vehicle foot stand (32). The throwing device (10) comprises a first supporting rod (14), a second supporting rod (19), a counterweight box (11), a guide ring (13), a first steering engine (16) and a rotary buckle (17), wherein two ends of the first supporting rod (14) and two ends of the second supporting rod (19) are respectively connected to the unmanned aerial vehicle foot stand (32), one side of the counterweight box (11) is movably connected to the first supporting rod (14) by means of rotary clamps (12), the other side of the counterweight box (11) is provided with a clamping groove (111), the first steering engine (16) is connected to the second supporting rod (19) by means of a steering engine fixing member (18), and the first steering engine (16) drives the rotary buckle (17) to rotate in the clamping groove (111) in order to loosen or lock the counterweight box (11). The traction device prevents a fire-fighting rope (40) from interfering with an unmanned aerial vehicle paddle during the descent of an unmanned aerial vehicle by means of the arrangement of the counterweight box (11).
