Abstract

The invention relates to a cable device anti-theft anti-injury technology, in particular to an anti-theft anti-injury cable well lid which solves the technical problem that facilities in a cable well are easy to steal, and pedestrians may be injured easily after a well lid is open at present. The anti-theft anti-injury cable well lid comprises a double-layer well lid which comprises an annular base located under the well lid and a top lid arranged above the base. An opening is formed in the annular edge of the base, a travel switch is arranged in the opening, and the travel switch is connected with a signal transmitter in series through a loop. The signal output end of the signal transmitter is connected with a data transmission unit (DTU) through a cable. The signal output end of the DTU is connected with a receiver through an optical fiber, and the travel switch is in opening-closing fit with the top lid. The anti-theft anti-injury cable well lid can effectively achieve real-time monitoring of the cable well lid and is simple in structure, low in production cost and very convenient to install.

Description

technical field [0001] The invention relates to an anti-theft and anti-mistake technology for cable equipment, in particular to an anti-theft and anti-mistake cable well cover. Background technique [0002] Nowadays, the original overhead lines in many cities have been changed into ground cables through engineering construction and transformation, and many cable inspection shafts have been added at the same time. Some communication optical cables also enter the ground through the cable channel from the original overhead. [0003] However, in actual operation, it was found that there are some potential safety hazards in the cable inspection shaft. 1. Some communication optical cable management units do not pay attention to safety precautions because they do not understand the knowledge related to power safety when they enter the cable inspection shaft privately to construct their optical cables. 2. The manhole cover of the cable inspection well is easy to open. After openin...
