UNDERWATER WORK AND PHOTOGRAPHING DEVICE FOR UNDERWATER WORK

摘要

PURPOSE: To dispense with movement and mounting of a photographing device by a diver and to perform safe and efficient underwater work by a method wherein a photographing robot is moved according to the change of a working side through remote control on a working ship and seated on the bottom to be monitored most suitable to photograph the vicinity of the working site. ;CONSTITUTION: By operating a propulsion thruster 24A and right and left thrusters 24B through the working of the robot operation device of an assist part 3 on a working ship 2, a photograph robot 1 is moved. A ballast tank control device is driven and ultrasonic pulses from ultrasonic oscillators 14A and 4B are received by ultrasonic receivers 21A and 21B for detecting the position of a position detecting means to detect a position and a robot body 20 is moved to a given bottom to be monitored as depth is confirmed by a depth meter, and seated on a bottom through seating legs 39. An illumination light 35 is lighted ON, and a dredging work is carried out through operation of a graph operating device 5 as a picture signal for a sea bottom photographed by a television camera 33 is watched.;COPYRIGHT: (C)1996,JPO
