Condition Monitoring System for Marine Hose

Abstract

The present invention provides a state monitoring system for a marine hose that can reliably grasp the state of the marine hose even in a harsh use environment. The conductive rubber (8) is extended in the outer surface layer (7) of the marine hose (1) that connects the connecting metal piece (2) to the inner surface layer sequentially from the inner peripheral side. Layer (4), reinforcing layer (5), and outer surface layer (7) are stacked to form the two ends of the hose body (3) in the longitudinal direction, and the conductive rubber (8) is connected to the conductive rubber (8) through the resistance sensing mechanism (9). ), the resistance value between at least two places spaced apart in the extending direction of ) is sensed, the sensed data is stored in the storage unit (10), and the state of the marine hose (1) is grasped based on the sensed data.

Description

Technical field [0001] The present invention relates to a state monitoring system for a hose for a ship. In more detail, it is more detailed to reliably grasp the state monitoring system of a hose for a state in which a motor hose is capable of reliably grasp the state of the hose of the ship. Background technique [0002] The hose is used when connecting the oil wheel or the like from the sea to the land facility or the like. The ship is used in various environments where the hoses are different in the natural environment such as waves, wind, and tides. In addition, these natural environments change. For example, when a typhoon is close to the waves, a larger external force from each direction acts on a hose for ships. Along this, there is a variety of deformations such as stretching, bending, and twisting on the hose of the ship. If the external force acting is too large to be too large, there is a risk of hose damage to the ship. If a fatal injury is generated in the hose of t...

Problems solved by technology

That is, in this marine hose, when the fluid does not leak from the inner rubber layer, abnormality in the state of the marine hose cannot be grasped in advance.

In addition, since only the presence or absence of fluid leakage from the inner rubber layer is sensed, it is impossible to know what kind of external force and what kind of deformation is usually applied to the marine hose.

Therefore, there is still room for improvement in order to grasp in advance and avoid fatal damage to marine hoses.
