DETAILED DESCRIPTION

[0022] The utility model will be further described below with reference to the drawings.

[0023] As shown in Figure 1 and Figure 2 , the tunnel environment monitoring device of an embodiment of the utility model includes fixed support 1 and monitor 2, fixed support 1 includes base 11, extension 12 and fixed seat 13, fixed seat 13 includes bottom plate 131 and side plate 132 oppositely arranged on both sides of bottom plate 131, and the side of side plate 132 away from bottom plate 131 is folded to the middle part of bottom plate 131. Base 11 is fixed on the wall of the tunnel by bolts, extension 12 provides space for the installation of bolts, and fixed seat 13 can clamp monitor 2.

[0024] As shown in Figure 3 , monitor 2 includes shell 21 and oxygen content sensor 221, toxic gas sensor 222, combustible gas sensor 223 and dust sensor 224 arranged outside shell 21, and shell 21 can be clamped between the two side plates 132.

[0025] Fixed support 1 is simple in structure and high in reliability, fixed seat 13 can clamp inserted monitor 2 by deforming to a certain extent, monitor 2 can be directly pulled out of fixed seat 13 when it needs to be disassembled for maintenance, and the operation is very simple. Oxygen content sensor 221, toxic gas sensor 222, combustible gas sensor 223 and dust sensor 224 on monitor 2 can monitor the environment in the tunnel in multiple aspects to ensure the safety of construction.

[0026] In an embodiment, the inside of shell 21 is provided with a control module, a communication module, a positioning module and a power supply module electrically connected with the control module, and oxygen content sensor 221, toxic gas sensor 222, combustible gas sensor 223 and dust sensor 224 are all electrically connected with the control module. The control module is responsible for receiving the monitoring data of each sensor and processing and storing the data; the communication module connects the control module and sends the processed data to the monitoring center through wireless or wired mode; the power supply module is used to provide stable power supply for each sensor and the control module; and the positioning module is used to determine the specific installation position of the tunnel environment monitoring device in the tunnel.

[0027] When the tunnel is long, the positioning module can be used to quickly locate areas where environmental anomalies occur, thereby determining the area where the dangerous environment is located.

[0028] like Figure 3 As shown, a mounting base 23 is provided at the bottom of the housing 21, and the mounting base 23 is fixed to the bottom of the housing 21 by a connecting column 24. The oxygen content sensor 221, the toxic gas sensor 222, the combustible gas sensor 223, and the dust sensor 224 are all arranged on the side of the mounting base 23 facing away from the housing 21. The centralized arrangement of the various sensors on the mounting base 23 simplifies the assembly process and facilitates the unified arrangement of the sensor cables.

[0029] Furthermore, a protective mesh 25 is provided on the side of the mounting base 23 facing away from the housing 21. The oxygen sensor 221, toxic gas sensor 222, combustible gas sensor 223, and dust sensor 224 are all housed within this mesh. This mesh protects the sensors, reducing their exposure to direct external forces. Furthermore, it does not block the sensors from contact with the tunnel air, allowing air to flow smoothly through it, allowing each sensor to accurately reflect the current tunnel environment.

[0030] like Figure 3 As shown, mounting base 23 is spaced apart from the bottom of housing 21. A wind speed sensor 225 is located on the side of mounting base 23 closest to housing 21. Wind speed sensor 225 monitors the air velocity within the tunnel, providing a more comprehensive view of the tunnel environment. Wind speed sensor 225 and other sensors are located on either side of mounting base 23, minimizing interference from other sensors on wind speed sensor 225.

[0031] In this embodiment, the connecting column 24 is a hollow structure, and the interior of the connecting column 24 can allow cables to pass through, thereby reducing exposure of the cables, providing a certain degree of protection for the cables, and being more beautiful overall.

[0032] like Figure 2 and Figure 3 As shown, an audible and visual alarm 26 is also provided on the top of the housing 21. The audible and visual alarm 26 is electrically connected to the control module inside the housing 21. When the indicators monitored by the various sensors exceed the safe value, the audible and visual alarm 26 will sound an audible and visual alarm, thereby providing a warning and prompting construction workers to evacuate the tunnel.

[0033] like Figure 2 and Figure 3 As shown, a display screen 27 is further provided on the surface of the housing 21. The display screen 27 can intuitively display various index data of the current tunnel environment, so that construction workers can conveniently view them.

[0034] In the embodiment, the tunnel environment monitoring devices are arranged at equal intervals along the length direction of the tunnel, so that the environment of the tunnel can be well monitored.

[0035] Further, the interval between the two adjacent tunnel environment monitoring devices is 15 meters.

[0036] Although the utility model has been described with reference to the preferred embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, the technical features mentioned in each embodiment can be combined in any way as long as there is no structural conflict. The utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
