The invention provides an anti-intrusion alarm system for cable trenches. The cable trench anti-intrusion alarm system includes: a receiving box, a circuit board, an alarm module, a detection module, a switch and a traction structure. The cable trench anti-intrusion alarm system is used for installation in the well. When the opening of the well is closed by the well cover, the switch can be turned off, thereby saving electricity. If a thief opens the well cover, the well cover rotates in the first direction, so that the well cover can pull the switch through the traction structure, so that the switch is closed, and then the circuit where the detection module and the alarm module are located is connected. When a thief enters the shaft, the detection module detects an obstacle in the shaft, and the detection signal generated by the detection module triggers an alarm from the alarm module, which can remind the shaft staff to check the condition of the shaft in time to prevent the thief from entering the cable trench through the shaft theft.
Description
technical field [0001] The invention relates to the technical field of cable trenches, in particular to an anti-intrusion alarm system for cable trenches. Background technique [0002] Usually, when laying optical cables, it is necessary to set up special trenches underground. In addition to protecting the optical cables, it is also convenient for later maintenance and management. Cable trenches of different specifications can be set up according to the laying base. Generally, the cable trenches are formed by cement pipes. Shafts are set at intervals to facilitate the entry of maintenance personnel. However, because the shafts are left unattended most of the time, and some shafts are in remote locations, there are currently some criminals illegally entering the shafts to steal various types of wires. [0003] In order to prevent the illegal intrusion of the above-mentioned trench wells, monitoring and alarm devices are often installed inside the wells, but the traditional an...
