Description

Technical Field

[0001] This utility model relates to the field of anchor bolt stress sensor technology, specifically an anchor bolt stress sensor with optical alarm function. Background Technology

[0002] The intrinsically safe anchor bolt (cable) stress sensor for mining is an automated monitoring device integrating microcomputer and computer technology that automatically measures and transmits the stress changes of anchor bolts and cables in underground coal mines. When the internal stress of the anchor bolt (cable) changes, the anchor bolt (cable) sensor head transmits the collected stress value to the sensor body in real time. The sensor body outputs the received data to the microcontroller circuit. The microcontroller circuit processes the collected signal and transmits it to the underground data acquisition substation. The data acquisition substation then transmits the data to the main equipment above ground via cable, realizing the surface monitoring of the stress changes of the underground anchor bolt (cable). It is an indispensable monitoring instrument for studying the stability of roadways and tunnels. Existing stress sensors lack a real-time alarm structure and cannot remind workers to react in time. Therefore, an anchor bolt and cable stress sensor with optical alarm function is needed.

[0003] The existing patent, CN213985467U, entitled "A Stress Sensor for Coal and Rock Anchor Bolts and Cables," relates to the field of stress sensor technology and discloses a stress sensor for coal and rock anchor bolts and cables. It includes a base with a receiving groove on the top side wall of the base. Symmetrical adjustment grooves are formed on opposite inner walls of the receiving groove. A locking hole is formed on the bottom of each adjustment groove near its bottom. Adjustment blocks are slidably connected within the adjustment grooves. The ends of two adjustment blocks away from the bottom of the adjustment grooves pass through the groove openings and extend outwards, and are jointly fixedly connected to a connecting plate. A sensor body is mounted on the top side wall of the connecting plate. A pull ring is fixedly connected to the upper end of the sensor body, and a first spring is fixedly connected to the bottom side wall of the connecting plate. When the stress sensor is needed, the pull ring disengages from the receiving groove; when not in use, the sensor body is stored back into the receiving groove, thus protecting the stress sensor.

[0004] The sensors in the aforementioned devices cannot effectively and quickly provide feedback to the outside world, and cannot quickly alert nearby staff to take appropriate measures when the stress exceeds the safety threshold, thus failing to meet people's usage needs. In response to the above situation, technological innovation is carried out based on the existing anchor cable stress sensor. Utility Model Content
