摘要： A spiral water intake valve (19) and a fire-fighting robot. The spiral water intake valve (19) comprises a valve body (111). A main valve core (112) is provided in the valve body (111), and a spiral water intake mechanism (113) is provided in the valve body (111). The spiral water intake mechanism (113) comprises a butt joint (16) and a connecting base (115). The main valve core (112) comprises a main valve sealing base (116) and a main valve screw (117). A water intake channel (123) is provided in the middle of an upper valve cover (77) of the valve body (111), the butt joint (16) is provided in the water intake channel (123), the main valve sealing base (116) is sealedly connected to the upper valve cover (77), and the main valve screw (117) is threadedly connected to the connecting base (115). The fire-fighting robot comprises a chassis (14) and a track (15). At least one spiral water intake valve (19) is provided on the track (15). A valve opening mechanism (100) is provided on the chassis (14). The valve opening mechanism comprises a fixing stand (1) and a valve shaft (2), a lifting rotating mechanism (6) is provided at the upper end of the valve shaft (2), a valve opening wrench (7) is provided at the lower end of the valve shaft (2), the valve opening wrench (7) is matched with the butt joint (16) in an inserted mode, and a sealing butt mechanism (20) is provided between the spiral water intake valve (19) and the valve opening mechanism (100). The spiral water intake valve can be automatically aligned and is accurate in alignment and good in tightness.
