Abstract

PURPOSE: To operate drilling in water by remote control, by making all parts watertight except a drill and its chuck and by containing a drill unit in a sealed box.
CONSTITUTION: All parts of drill unit 18, which is placed in sealed box 19, that come into contact with water except chuck 16 and drill 15 fitted to it, which directly operate drilling, are completely isolated from water. At the back of the above- mentioned drill unit 18, there are control components required for remote control, such as limit switch 31, miniature cylinder 32, and check valve 33, which are closely connected with rod 32, which shows the moving-in and moving-out of the drill. These control components are connected by means of an in-air-operation panel and a plurality of watertight hoses. By remote operation of these components, instructions for various under-water operations of drill unit 18 are given and monitoring is carried out.
