WORKING VESSEL ROUTE DEVIATION PREVENTION WORKING SPEED CONTROL MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a device capable of accurately and easily performing treatment work of a net and whole control work such as navigation of a vessel as a movement work navigation means of a treatment work vessel of the net stretched by a strut or a buoy with a fixed interval such as a laver net.;SOLUTION: A pressure sensitive control valve 3 is activated while utilizing load pressure variation applied to a pressure flow rate type drive device 11 of a net winding/feeding machine in order to automatically control the whole working speed constant by adjusting the working speed of the net winding/feeding machine 1 by a net winding/feeding machine operation valve 2. Thereby, while a linear advancement propulsion unit 4 is driven and thrust is adjusted, and while load balance of the net winding/feeding machine and the linear advancement propulsion unit is retained, the working navigation speed is adjusted to meet the working pace. A sensitive rope is stretched to an inner edge of a passage and it is sensed by a deviation sensitive control valve, such that an advancement direction of the working vessel is not deviated to left and right sides by a tidal current or a wind pressure. While automatically controlling the thrust of the lateral advancement propulsion unit to adjust the deviation, the working navigation can be performed.;COPYRIGHT: (C)2008,JPO&INPIT
