Integrated monitoring links for underwater moorings

Abstract

An integrated monitoring chain ring used for underwater mooring equipment comprises a ring and a mounting cover which is fixedly connected to the transverse direction of the ring; the mounting cover comprises a shell section; the external walls of the two ends of the shell section are fixedly connected to the internal peripheral walls of the two ends of the ring in the transverse direction; two strain sensing modules, two data collection modules and a wireless signal transmission module are mounted in the mounting cover, wherein the two strain sensing modules are correspondingly arranged on the internal walls of the two ends of the shell section fixedly connected to the internal peripheral wall of the ring; signal transmission cables are arranged between the strain sensing modules and thedata collection modules; the two data collection modules correspondingly receive strain signals output by the two strain sensing modules; communication cables are arranged between the two data collection modules and the wireless signal transmission module; and a watertight wireless signal transmission hole is formed in the mounting cover. According to the integrated monitoring chain ring used forthe underwater mooring equipment, an appearance of an anchor chain connecting piece with a cross rail is realized; and the problems of dispersed structure and complicated assembling of an existing like device are solved while stress real-time monitoring is realized.

Description

technical field [0001] The invention relates to the technical field of ship and marine engineering testing, in particular to an integrated monitoring chain link for underwater mooring equipment. Background technique [0002] Mooring positioning is the most commonly used offshore positioning method in the field of ships and ocean engineering. It is widely used in marine engineering equipment such as floating platforms, offshore airports, floating production systems, and marine engineering ships. Mooring equipment includes anchor chains, mooring cables, shackles, etc. On the one hand, mooring equipment reduces the movement of the floating platform in the vertical plane (such as rolling, The horizontal movement under load ensures the normal operation and survival of the floating platform. However, the floating body is subjected to alternating loads such as wind, waves, and currents for a long time at sea, so that the mooring equipment is constantly subjected to random dynamic ...

AI Technical Summary

Problems solved by technology

The disadvantages of this monitoring structure are: (1) The shape of the stress sensing device is quite different from that of the anchor chain, and it cannot be well integrated into the mooring equipment. A series of cumbersome work such as installation, debugging, protection, and disassembly are required when retracting (2) The mooring cable is in the form of a "catenary" underwater, and there is an action angle between the anchor chain links, and the stress sensing device arranged at the end cannot well reflect the force of the entire mooring chain Happening

The above defects make this kind of monitoring device installed on the anchor chain with a clamp carrying a sensor device greatly reduce the usability of the equipment, and also prevent it from being widely used in the civilian field
