The sensing system for opening and closing the bow door of a ship

Abstract

The invention relates to a raising and laying down sensing system of a ship bow door. The system comprises a hydraulic control system and a data acquisition and processing system; the hydraulic control system comprises an oil tank, an oil absorption filter, an oil pump, a one-way valve, an electro-hydraulic directional valve, a first one-way proportional flow valve, a second one-way proportional flow valve, a first double-action single-piston-rod oil cylinder, a second double-action single-piston-rod oil cylinder, a first one-way throttling valve, a second one-way throttling valve, a manual reversing valve, an overflow valve and an oil returning filter set; and the data acquisition and processing system comprises an information perceiving module, a data analysis and processing module, a master control table, a PLC, a man-machine interaction module and a sound-light alarm module. On the basis that the hydraulic control system is redesigned, control precision of bow door raising and laying down is improved through data measured by multiple sensors, and the aim that materials in a ship can be safely and rapidly unloaded and loaded is achieved.

Description

technical field [0001] The invention relates to a sensing system for launching and launching a bow door of a ship, in particular to a system for monitoring and real-time controlling the process of launching and launching a bow door of a ship. Background technique [0002] When the boat reaches the top beach to lift and release the bow door, because the view of the operator in the bridge is obstructed by the large hatch, it is impossible to accurately judge the opening of the bow door. An observer must stand in the large cabin at the bow The front end of the cover gives instructions to the operator who lifts and lowers the bow door. These technical means are outdated, and when the ship raises and lowers the bow door on the top of the beach under bad weather conditions, the traditional method will endanger the life safety of the observers and affect the safety of the inside of the ship. Safe and fast loading and unloading of materials. [0003] The bow door lift control adopt...

Problems solved by technology

Since the speed of the bow gate is controlled by controlling the flow of the one-way throttle valve, the flow through the throttle valve is realized by adjusting the opening of the throttle with the handle, and its accuracy is not high, and it still depends on the bow valve. The bow door is lowered by the weight of the door itself. If the oil cylinder is not synchronized during the bow door opening process, the bow door will be unbalanced. In severe cases, the bow door hinge will break and the bow door will fall.
