PURPOSE:To obtain an automatic device which can perform reliable operation by fixing a plate shaped liquid sucking member, which can be contacted with a surface which is to be checked and located at a ceiling, to the upper end face of a rotary tube. CONSTITUTION:A small arm 109 of a manipulator 100 which is provided in a water chamber 4 is moved to the position directly over a manhole 5, and the osmosis device 10 is mounted to the small arm 109. Then, the osmosis device 10 is transferred to the position directly under the end hole of a small vapor pipe 2 in the water chamber 4, i.e, where a blank plug 7 which requires the osmosis flaw detecting check is welded for sealing by the rotation and the stretching and contracting movement of a main arm 107. Then, osmosis liquid which is supplied from an osmosis liquid supplying tube 48 is flowed into felt 42 through an osmosis liquid supplying tube 47 and a supply hole 46, and attached to the seal welded part of the blank plug 7, which is contacted with the felt 42. When a rotary motor 35 is operated, the rotary tube is rotated together with the felt 42, and the attachement of the osmosis liquid to the seal welded part is further ensured. |
