[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides an automatic inspection device for underground tunnels, such as Figure 1-Figure 3As shown, it includes a motor drive device, an inspection module, a pulley track device and a control system. The motor drive device includes: a drive motor 101, which forms a complete rotary mechanism with a drive wheel 103, a transmission belt 104, and a fixed pulley 102; the inspection module includes: an inspection box 202, a connecting rod 201 connecting the inspection module and the mobile wheel 303, and a rigid connecting rope 207 between the connecting rod 201 and the transmission belt 104; the pulley track device includes a limiting track 301, a pulley groove 302 is provided on the inner side of the limiting track 301, and a mobile wheel 303 is provided on the inner side of the pulley groove 302. A transmission belt hanging ring 304 is installed on one side of the upper part of the limiting track 301, and a lower transmission belt groove 305 is installed on one side of the lower part of the limiting track 301. Since the transmission belt 104 itself does not bear weight, this design not only simplifies the drive device but also improves the stability of the entire drive system. The inspection module's movement direction is controlled by controlling the direction of the drive motor 101, which drives the transmission belt in both forward and reverse directions. Meanwhile, the mobile wheel 303 and the limiting track 301 carrying the inspection module are mounted on the side of the roadway, which reduces space usage and is easy to install and maintain. The pulley track assembly is not directly connected to the drive system, making it simple and easy to maintain.

[0023] In this embodiment, the transmission belt 104 is a closed belt structure, one end of which is connected to the driving wheel 103 and the other end is connected to the fixed pulley 102. The driving wheel 103 and the fixed pulley 102 are connected and transmitted through the transmission belt 104. The driving motor 101 directly drives the driving wheel 103 to rotate. The driving motor 101 is connected to an external control system, and the speed and direction of the driving motor 101 are adjusted by the control system.

[0024] Specifically, the bottom end of the connecting rod 201 is fixed to the top of the inspection box 202, and a cross bar is installed on the top of the connecting rod 201. The bottom of the cross bar is fixed to the upper surface of the lower transmission belt 104 through a rigid connecting rope 207. One end of the cross bar is rotatably connected to the axis of the moving wheel 303 through a bearing. When the transmission belt 104 moves, the connecting rod 201 is driven to move through the rigid connecting rope 207, and then the inspection module is driven to move horizontally, and the stability of the operation is ensured by the moving wheel 303.

[0025] Furthermore, a network camera 204, an air quality sensor 205, a temperature and humidity sensor 206, and a battery 203 are installed inside the inspection box 202. The network camera 204, the air quality sensor 205, and the temperature and humidity sensor 206 are powered by the battery 203. The inspection box 202 contains two sets of batteries 203 to power the network camera 204, the air quality sensor 205, the temperature and humidity sensor 206 and other equipment in the inspection box 202, and the battery 203 is replaceable. The network camera 204 directly transmits image information in the lane, and the air quality sensor 205 and the temperature and humidity sensor 206 directly detect whether the working environment in the lane is safe. The image information and working environment information are directly transmitted to the command center via the network to realize remote monitoring. The air quality sensor 205 and the temperature and humidity sensor 206 can also be replaced with smoke sensors, noise sensors, air pressure sensors, etc. according to the needs of the working environment.

[0026] Furthermore, the pulley groove 302 is used to place the moving wheel 303, and the limiting track 301 is used to guide the movement of the inspection module. The moving wheel 303 moves in the pulley groove 302 to ensure the stable operation of the inspection box 202.

[0027] Furthermore, the transmission belt hanging ring 304 is used to limit and support the upper transmission belt 104, and the lower transmission belt groove 305 is used to lift and support the lower transmission belt 104 to ensure that the transmission belt 104 will not be deformed or broken due to tension.

[0028] Furthermore, the limiting track 301 is installed on an inner wall of one side of the pipeline, the driving motor 101 is installed at one end of the pipeline, and the fixed pulley 102 is installed at the other end of the pipeline.

[0029] When using the automatic underground tunnel inspection device of the present invention, the drive motor 101 is first activated through an external control system. This activates the drive motor 101 and drives the drive wheel 103 to rotate. Because the drive wheel 103 is connected to one end of a transmission belt 104, the rotation of the drive wheel 103 also drives the transmission belt 104. The other end of the transmission belt 104 is connected to the fixed pulley 102, forming a complete rotary mechanism. This allows the transmission belt 104 to circulate between the drive wheel 103 and the fixed pulley 102.

[0030] When the transmission belt 104 moves, it drives the connecting rod 201 via the rigid connecting rope 207. The bottom end of the connecting rod 201 is fixed to the top of the inspection box 202, so the movement of the connecting rod 201 drives the inspection box 202 along with it. Simultaneously, the top end of the connecting rod 201 is rotatably connected to the axis of the moving wheel 303 via a bearing. The moving wheel 303 is positioned in the pulley groove 302. This ensures the stable operation of the inspection box 202 and guides its movement along the limiting track 301.

[0031] As inspection box 202 moves, its internal network camera 204 transmits real-time image information from the tunnel. Air quality sensor 205 and temperature and humidity sensor 206 monitor the safety of the tunnel's working environment in real time and transmit this information directly to the command center via the network, enabling remote monitoring. If necessary, air quality sensor 205 and temperature and humidity sensor 206 can be replaced with other types of sensors, such as smoke sensors, noise sensors, or air pressure sensors, depending on the working environment.

[0032] When the movement direction of the inspection box 202 needs to be changed, the control system only needs to adjust the direction of the drive motor 101. Since the transmission belt 104 itself does not bear weight, the stability of the entire drive system is improved, and the structure of the drive device is also simplified.

[0033] In general, this automatic inspection device for underground tunnels realizes the automatic operation of the inspection module through the ingenious combination of motor drive and pulley track device, improves the inspection efficiency of underground tunnels, reduces the labor intensity of inspection personnel, and provides strong data support for mine safety management.

[0034] Finally, it should be noted that the electronic components of the network camera 204, air quality sensor 205, temperature and humidity sensor 206, etc. in this embodiment are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
