Problems solved by technology

[0003] An important issue in the installation of the optical fiber strain sensor is the fixing of the signal transmission cable of the optical fiber strain sensor, because the vibration, tension and compression caused by the combined action of wind, waves and currents on the offshore platform are relatively fragile to themselves. fiber optic cable is a severe test
After searching the existing technology, it is found that the current optical fiber fixing device and fixing method are mainly focused on the fixing of the optical cable on the ground, such as patent CN200910197339, and there is no related patent for the optical fiber fixing device and fixing method of the underwater rod of the marine jacket platform

Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0042] In this example, if figure 1 , figure 2 , image 3 , Figure 4 As shown, the selection of monitoring and control room 1: sunshade and rainproof and stable power supply are the basic conditions, and air conditioning temperature control and air filtering device are the preferred locations. At the same time, you can also choose to use the field cabinet, which must be equipped with an air circulation system and a temperature control system. A monitoring control room 1 is placed at the plac...

Abstract

The invention provides a cable fixing device which comprises a groove body, shackles and supporting cards. The shackles and the supporting cards are arranged on the inner sides of the groove body, arranged on the same axis and the same in height. The height of the shackles and the supporting cards is lower than that of the side walls of the groove body. The shackles are two in number. The supporting cards are two in number. The two shackles are arranged at the two ends of the groove body respectively and arranged between the two supporting cards. The invention further provides a cable fixing system. By means of the cable fixing device and system, effective fixing of cables of fiber optic sensors of underwater rod pieces of an ocean guide pipe frame platform can be achieved, and severe shaking, pulling and pressing of the cables are avoided.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an optical cable fixing device and system. Background technique [0002] At present, there are not many structural health monitoring of jacket platforms in service, but with the emphasis on the safety of offshore platforms, structural health monitoring will become more and more important. Therefore, real-time online and accurate assessment of the health status of the jacket platform, real-time monitoring of the safety and integrity of the structure, and early positioning and repair of damaged rods can reduce the incidence of offshore oil and gas accidents. small economic loss. However, relying on manual detection or ROV detection, ultrasonic method, and radiation method detection can only be "post-event" monitoring, and online real-time monitoring of structural integrity and safety cannot be realized under harsh sea conditions. Therefore, it is more and more inclined...
