PURPOSE:To prevent release of air supplied into a main unit and surely float a device even if the device is unsuccessfully seated to the sea bottom and laterally turned, by providing a flexible seawater circulative pipe, in the bottom end of which a weight part is formed, to a seawater circulative port provided to the bottom part of a diving main unit. CONSTITUTION:The bottom end of a flexible seawater circulative pipe 5 turnably inserted into a seawater circulative port 4 formed in the bottom part is formed to a weight part 6. By any chance even if a diving main unit 3 is unsuccessfully seated to the sea bottom and laterally turned, the pipe 5 is flexed and air in the unit 3 is never released, while a valve of a cylinder 2 is opened by an instruction signal from a ship and air is supplied into the unit 3 to lift the unit, and when the unit 3 recovers its vertical condition, a valve device 14 is opened to release air in the unit 3, and the main unit is again descended and seated. And then air is supplied into the unit 3 to surely float the unit. |
