Abstract

PURPOSE:To observe the surface condition of a machine, etc., installed under water by putting a main body which floats on the surface of water closely to a target and sucking it fixedly with a mouthpiece, and sending an observing device upwardly out of a sending-out device suspended below the main body. CONSTITUTION:Water is fed from a pump 17 for propulsion to nozzles 13 and 14 through a flexible hose 8 to put a mother ship 1 closely to a pumping pipe 11 by utilizing the reaction force of injected water, and the mouthpiece 3 is sucked fixedly to the pumping pipe 11 by the suction of an underwater pump 4. A cable 10 is sent out of the sending-out device 6 suspended below the mother ship 1 through an air cylinder and the observing device 7 provided atop it is sent to near the impeller 12 of the pumping pipe 11 while facing up. Consequently, the surface condition of the object (impeller 12) under water is observed regardless of the water turbidity.
