Title:
UNDERWATER FLOATING DEVICE AND DEPTH CONTROL METHOD
Document Type and Number:
Japanese Patent JP2017149195
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable control for floatation/precipitation without increasing in size of a control mechanism to solve a conventional issue that an increase in weight of a device requiring floatation/precipitation may cause the mechanism for adjusting floatation of the device to also increase in size.SOLUTION: An underwater floating device 1 moored in water by a mooring rope comprises: a propeller 11 as thrust control means, which controls a thrust in a substantially horizontal direction and changes a depth where the own device is in; a rotary shaft 12; and a control part 14. Changing the thrust of the underwater floating device by this thrust control means can control the depth. Thereby, controlling floatation/precipitation of the underwater floating device is enabled without providing a large-sized mechanism and the like for the floatation adjustment.SELECTED DRAWING: Figure 2
