Embodiment
[0026] Example: such as Figure 1-Figure 8 As shown, a tunnel operation safety monitoring and protection system includes a running device 1, a collecting device 2, and a detection device 3. The running device 1 includes a bottom plate 101, and a bracket 105 is fixedly installed on the top surface of the bottom plate 101. The bracket The top of the bracket 105 is provided with a collection device 2 for cooperating with the detection device 3 to collect gases of different densities. The top of the support 105 is also provided with a detection device 3 for detecting the collected gas. tube 205 , the collection device 2 is connected with the detection device 3 through the communication hose 205 .
[0027] When the construction workers need to enter the tunnel for construction, start the walking device 1, and the walking device 1 carries the construction workers into the tunnel. The construction workers move quickly in the tunnel by controlling the walking device 1, and start the col...

The invention discloses a tunnel operation safety monitoring and protecting system, and relates to the technical field of electric power safety, the tunnel operation safety monitoring and protecting system comprises a walking device, a collecting device and a detecting device, the walking device comprises a bottom plate, and a support is fixedly mounted on the top surface of the bottom plate; the top of the support is provided with a collecting device used for being matched with the detection device to collect gas with different densities, the top of the support is further provided with the detection device used for detecting the collected gas, the collecting device comprises a communicating hose, and the collecting device is connected with the detection device through the communicating hose. When harmful gas with high strength is detected, constructors and related construction tools can be carried to rapidly retreat; the collecting device can assist the detection device in collecting gases with different densities and different heights in the tunnel, so that the detection result is more comprehensive and accurate; the detection device can perform dual detection of toxicity and flammability on collected gas, so that potential safety hazards caused by harmful gas in the tunnel to constructors are reduced.
Description
technical field [0001] The invention relates to the technical field of electric power safety, in particular to a tunnel operation safety monitoring and protection system. Background technique [0002] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. During tunnel mining or construction, various toxic and harmful gases will appear, such as carbon monoxide, carbon dioxide, oxygen, sulfur dioxide, methane, PM10 hydrogen sulfide, etc. These gases accumulate in the tunnel, and as the concentration increases, it will bring Various hidden dangers. If tunnel construction personnel rush into without protection and detection, there will be a fatal risk. Therefore, it is very important to protect the personal safety of construction personnel in the tunnel. [0003] In...
