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.

Embodiment Construction

[0026] Hereinafter, the state monitoring system of the marine hose of this invention is demonstrated based on embodiment shown in a drawing.

[0027] Figure 1 ~ Figure 3 The exemplified marine hose state monitoring system (hereinafter referred to as a monitoring system) of the present invention includes a specific embodiment of the marine hose 1 , a resistance sensing mechanism 9 for sensing a resistance value, and a storage unit 10 . The marine hose 1 has a hose main body 3 and connecting metal fittings 2 respectively connected to both longitudinal ends of the hose main body 3 .

[0028] The hose main body 3 has: an inner surface layer 4; a reinforcement layer 5 (a main reinforcement layer 5A and a main body wire layer 5B) arranged on the outer peripheral side of the inner surface layer 4; and an outer surface layer 7 arranged on the reinforcement layer 5 the outer peripheral side. Other required members are appropriately provided on the hose main body 3 . Since the marin...

Abstract

Provided is a marine hose status monitoring system capable of definitively ascertaining the status of a marine hose even in harsh operating environments. The present invention involves: extending a conductive rubber 8 inside the outer-surface layer 7 of a marine hose 1 obtained by connecting a connection fitting 2 to both end sections in the lengthwise direction of a hose body 3 constructed by layering an inner-surface layer 4, a reinforcing layer 5, and an outer-surface layer 7, in order from the inner-circumferential side; using a resistance detection mechanism 9 to detect the electric resistance between two or more locations separated from one another in the direction of extension of the conductive rubber 8; storing the detection data in a storage unit 10; and ascertaining the status ofthe marine hose 1 on the basis of the detection data.

Description

technical field [0001] The present invention relates to a state monitoring system of a marine hose, and more specifically, to a state monitoring system of a marine hose capable of reliably grasping the state of a marine hose even in a harsh use environment. Background technique [0002] Marine hoses are used to connect oil tankers and other facilities at sea to transport crude oil and the like. Marine hoses are used in various environments with different natural environments such as waves, wind, and tides, and these natural environments change constantly. For example, when a typhoon or the like approaches and the waves become high, larger external forces from various directions act on the marine hose. Along with this, various deformations such as stretching, bending, and torsion occur in marine hoses. If the external force acting on the marine hose is too large and the deformation increases, there is a risk of damage to the marine hose. If fatal damage occurs to a marine ...
