The invention provides a water filling nozzle protection device for a passenger train, a carriage and the passenger train. The protection device comprises a fixed plate, a protection plate and movableturning plates. A through hole for a water filling nozzle to penetrate through is formed in the fixed plate. The protection plate is arranged at the bottom of the fixed plate, and a cavity for accommodating the water filling nozzle is defined by the protection plate and the fixed plate. The movable turning plates comprise the first movable turning plate and the second movable turning plate whichare in butt joint with each other, the opposite sides of the first movable turning plate and the second movable turning plate are both rotationally connected with the protection plate, and the adjacent sides of the first movable turning plate and the second movable turning plate both rotate towards the interior of the cavity to open the cavity. The cavity is closed after the first movable turningplate and the second movable turning plate rotate in the opposite directions, and a limiting part is further arranged on the protection plate. The water filling nozzle is effectively wrapped and sealed, the water filling nozzle is prevented from being polluted by dust, cleanness and sanitation of the water filling nozzle are fully guaranteed, and the device is simple in structure, small in size, convenient to operate, stable in performance, practical, reliable and easy to maintain.
