Abstract

The invention provides a field rapid installation device for a sensing optical cable. The device comprises a metal panel; the metal panel is provided with a positioning installation hole and a fine adjustment installation hole; an optical cable slot is formed in the lower part of the metal panel; and a plurality of metal protruding points are arranged in the optical cable slot. The device is smallin size, easy to manufacture, easy to operate, rapid in installation, low in reworking rate, low in cost, small in optical path micro-bending loss and reliable in anchoring effect, and is suitable for installation of sensing optical cables with different sizes, structures and cladding materials; and the sensing optical cable can be effectively fixed on the surfaces of concrete and steel structures.

Description

Technical field: [0001] The invention belongs to the technical field of optical cable installation, and in particular relates to a device for rapid on-site installation of sensor optical cables. Background technique: [0002] Optical fiber sensing technology is a new type of sensing technology that has gradually developed and matured in recent years. Because of its long-distance, corrosion resistance, anti-electromagnetic interference, and good durability, it has been widely used in underground engineering, slope engineering, bridge and tunnel engineering , Pipeline engineering and other large-scale basic engineering fields, and achieved good results, successfully overcoming the disadvantages of traditional sensor measuring points, such as cumbersome layout, low survival rate, and susceptibility to electromagnetic interference. The sensing optical cable in the sensing system is both a sensing element and an optical signal transmission channel, and is an important part of the enti...

Problems solved by technology

[0003] At present, there have been many project examples at home and abroad that use sensing optical cables to monitor tunnel deformation and pipeline stress, but the monitoring range is relatively small, and most of them are used as engineering demonstration sites, and the scale length is not completely covered. The reason for this phenomenon is There are many aspects, but the installation speed of the sensing optical cable is a problem to be solved urgently in its large-scale application, so it is necessary to provide a new installation process that can effectively improve the installation speed and accuracy to solve such problems
