Abstract

The invention discloses an optical fiber sensing device based on hydraulic linkage. The optical fiber sensing device comprises a driving cylinder body, a driving piston, a transmission connecting rod,a compression spring, a guide pipe, a driven cylinder body, a driven piston and an optical fiber hook, wherein the driving piston is sleeved with the driving cylinder body; the transmission connecting rod penetrates through an upper cover of the driving cylinder body to be connected with the driving piston; the compression spring sleeves the part, exposed out of the driving cylinder body, of thetransmission connecting rod; one end of the compression spring is connected with the upper cover of the driving cylinder body; one end of the compression spring is connected with one end, away from the driving piston, of the transmission connecting rod outside the driving cylinder body; the driving cylinder body is connected with the driven cylinder body through a guide pipe; the driven piston issleeved with the driven cylinder body; and the optical fiber hook is connected below the driven piston. Sensing is achieved by directly utilizing idle fiber cores in the optical fibers or optical cables, the optical fibers or optical cables used for optical fiber sensing do not need to be laid again, the adaptability of the device is improved, the technical difficulty of installation and construction is reduced, and the device has good adaptability in a severe underground tunnel environment.

Description

technical field [0001] The invention belongs to the technical field of safety precautions for cable tunnel inspection wells, and more specifically relates to an optical fiber sensing device based on hydraulic linkage. Background technique [0002] The inspection manhole cover of the cable tunnel is an openable closure for the inspection well head of the cable tunnel (ditch). In order to facilitate opening, it is often pressed directly on the well seat of the inspection wellhead. However, manhole covers are stolen and manhole covers are washed away by running water caused by heavy rains. Especially when water is flooded, inspection wells without manhole cover pressing have brought huge safety hazards to pedestrians and vehicles on the road. Most of the traditional manhole cover alarms are electronic alarms, which send alarm signals through the mobile network. When the electronic alarm is far away from the mobile communication base station or the alarm is blocked due to the ...
