<P>PROBLEM TO BE SOLVED: To simplify a constitution, and to reduce equipment cost and running cost. <P>SOLUTION: This aircraft airframe cleaning device includes: an actuator 81 arranged between piping 33 and a branch pipe 34 and having a cylinder 83, a piston 84 stored in the cylinder 83 and a rod 85 fixed to the piston 84; and a link mechanism 82 connected to the rod 85. The aircraft airframe cleaning device is constituted so that when supplying wash water, the piston 84 and the rod 85 move in one direction by pressure exerted by the wash water, the piping 33 and the branch pipe 34 are communicated, and the branch pipe 34 swings so that an injection nozzle approaches an aircraft by the link mechanism 82, and when the wash water is not supplied, the piston 84 and the rod 85 move in the other direction by an energizing means 95 arranged in the actuator 81, communication between the piping 33 and the branch pipe 34 is cut off, and the branch pipe 34 swings so that the injection nozzle goes away from the aircraft by the link mechanism 82. <P>COPYRIGHT: (C)2013,JPO&INPIT |
