Description

Technical Field

[0001] The utility model relates to the field of data collection boxes, in particular to a tunnel safety automatic monitoring data collection box. Background Art

[0002] The tunnel construction safety tracking warning system uses safety monitoring sensors and data acquisition devices installed at various sections within the tunnel to collect real-time information on the surrounding rock safety status. Base stations are also installed within the tunnel's working area to provide real-time three-dimensional positioning of workers. This information is then transmitted via a self-built industrial wireless network within the tunnel to a collection substation at the tunnel entrance or on the surface. The collection substation aggregates the data and transmits it via wired connections to a central server. The monitoring center processes and analyzes the data to determine the surrounding rock installation status and personnel location. When the monitoring data indicates an unsafe surrounding rock in a specific area, a software program establishes an electronic fence. When a construction worker's coordinates are within this area, the system transmits the surrounding rock safety status and warning information to the worker's mobile device via the self-built industrial wireless network, alerting them to leave immediately. The warning ends when the worker successfully leaves the area and reaches a safe zone. The system primarily consists of two subsystems: hardware and software. The hardware subsystem comprises an automatic structural displacement monitoring system and a personnel locator. The software system provides functions such as monitoring data collection, analysis, and early warning. The monitoring system consists of an automatic structural displacement monitor, a dome reflector, and the like. The automatic structural displacement monitor consists of a housing, a laser sensor, a communication module, a gimbal, a power supply (a high-energy lithium battery), and a data acquisition device, and the laser sensor, communication module, gimbal, power supply, and data acquisition device are all installed inside the housing. During use, it is often necessary to disassemble and assemble the housing so as to inspect and repair the laser sensor, communication module, gimbal, power supply, and data acquisition device installed therein. However, traditional housings are often assembled with multiple bolts, so when disassembling and assembling the housing, tools are required to disassemble and assemble the multiple bolts one by one. This process is relatively cumbersome and complicated, which in turn results in a low efficiency in disassembly and assembly of the housing, and ultimately, a low efficiency in the inspection and repair of the equipment installed inside the housing.

The baffle 7 is fixedly mounted on the inner side of the inner wall of the frame 6. The wall of both sides of the frame 6 is symmetrically provided with a second jack 8. When it is necessary to inspect the equipment in the data acquisition box body 1, and thus it is necessary to remove the protective door 2 from the data acquisition box body 1, the rotating circular plate 13 and the elliptical plate 14 on the fixing assembly 4 can be rotated ninety degrees on the mounting frame 9, so that the elliptical plate 14 is Figure 5 The horizontal state shown in the figure is changed to a horizontal horizontal state. At this time, the moving block 16 and the insertion rod 19 will lose the obstruction of the elliptical plate 14, so that under the elastic force of the return spring 12, the moving block 16 and the insertion rod 19 will slide inward on the guide rod 11 on the limit assembly 3. Finally, when the insertion rod 19 is removed from the first insertion hole 5 on the data acquisition box body 1, the fixation of the protective door 2 is released, and then the protective door 2 can be taken out from the data acquisition box body 1; when the protective door 2 needs to be installed in the data acquisition box body 1, the rotating circular plate 13 and the elliptical plate 14 can be rotated ninety degrees on the mounting frame 9, so that the elliptical plate 14 is in a state of being fixed.
