PURPOSE:To facilitate the development, lifting and reception of an apparatus and to make it possible to lower an accommodation height on a ship, by hanging a rope for connecting a buoy and the gun supported by the buoy in a twofold state. CONSTITUTION:A gun 3 is attached to one end of the rope 34 connected to buoys 9 floated on the surface of the sea to emit a sonic wave. An intermediate beam 35 is provided to the intermediate position of the rope 34 which is, in turn, hung in a twofold state while said beam is suspended from the trolley 18 of a rail 31. The attracting part of a magnet 33 is adhered to the beam 35 to successively move the gun 3 above a well 30 and, subsequently, the beam 35 is separated from the trolley 18 to be immersed in the sea. Therefore, the developing lifting and receiving work of a probing apparatus becomes safe and easy, a large number of workers are not necessary and, because the connecting rope 34 is hung in a twofold state through the intermediate beam 35, an accommodation height on a ship can be lowered. |
