Description

Technical Field

[0002] Tunnels are engineering structures buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels; the structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel door, and the ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] Announcement No.: CN105823510B discloses a tunnel environment real-time monitoring and early warning system based on the Internet of Things. The system's fixed points are fixed by using quick-drying cement or other strong adhesives, and then the tunnel is monitored. The collected tunnel environment information is then displayed through an information display platform and a receiving device client. The collected data can also be analyzed. When abnormal data values ​​appear, early warnings are issued through text messages, emails, and receiving device clients, thereby improving the quality and efficiency of tunnel environment monitoring. Announcement No.: CN110320177A discloses a tunnel gas monitoring, recording, and early warning system and a monitoring method thereof. The gas in the tunnel is monitored in real time by a gas detection sensor on a monitoring box body, and the display alarm device is used to facilitate the staff in the tunnel to understand in real time and to provide timely alarms. The monitoring results of the monitoring box body are transmitted to a remote server or a central control room in real time through a wireless relay device and a wireless transmission module, so that the staff outside the tunnel can monitor the environment in the tunnel in real time.

[0004] Although the above patents have achieved multi-point detection in the tunnel and have achieved the transmission of the situation in the tunnel to the staff through the network, the above content still has shortcomings, as follows: 1.

This technology is a prior art and will not be elaborated again, so that the data monitored by the detection component 7 can be displayed by the receiving device 12, and then the data transmitted to the controller 11 is transmitted to the Internet of Things, and then transmitted to the receiving device 12 through the Internet of Things, so that the staff can monitor the situation in the tunnel section 1 at all times, so as to warn the staff and enable them to take appropriate measures in advance.

[0062] In order to facilitate the transmission of information in the tunnel segment 1 to the drivers so that they can take appropriate driving measures in advance, in this embodiment, a plurality of vertically arranged support frames 4 are fixedly provided on the lower side of the rear end of the rearmost tunnel segment 1, and a display screen 5 is fixedly provided at the lower end of the support frame 4.

In this embodiment, an infrared receiver is provided in the shell 6, and an infrared transmitter is provided in the display screen 5. The display screen 5 will continuously emit infrared signals, and the shell 6 will transmit infrared signals through the display screen 5.

This infrared signal positioning is a prior art and will not be elaborated on again. When the plug connector 8 is inserted into the plug slot and electrically connected to the display screen 5, the detection data can be displayed on the display screen 5. When the plug connector 8 moves with the movement of the shell 6, the plug connector 8 passes through the plug slot and is connected to the receiving end of the display screen 5. After that, the display screen 5 can display the collected information on the display screen 5 so that the driver can see the information, so as to serve as an early warning to the driver, so as to improve driving safety. The connection between the plug connector 8 and the display screen 5 is a prior art and will not be elaborated on again.

[0063] The controller 11 is signal-connected to the plug connector 8 so as to transmit data to the display screen 5 via the plug connector 8 .

[0064] In order to facilitate the movement of the slide plate 9 to different heights, in the present embodiment, a detachable and multiple spaced arc-shaped slide bars 2 are provided on the inner top wall of each tunnel segment 1, and each arc-shaped slide bar 2 is transmission-connected with a first driving mechanism 3. The first driving mechanism 3 is driven to start so that the first driving mechanism 3 can slide back and forth along the arc-shaped slide bar 2 to adjust different heights, thereby also driving the detection component 7 to detect different heights. The first driving mechanism 3 is transmission-connected with a slide plate 9 extending along the direction of the tunnel segment 1, and the first driving mechanism 3 drives the slide plate 9 to reciprocate along the arc-shaped slide bar 2.

[0065] Specifically, the first driving mechanism 3 includes a first driving device 301, a fixed plate 302 and a plurality of roller limiting assemblies 303 rotatably arranged on the fixed plate 302. In this embodiment, the first driving device 301 is a first servo motor, and the slide plate 9 is fixedly arranged at the bottom of the fixed plate 302.

[0066] Two upper and lower adjacent roller stop assemblies 303 are clamped on the arc-shaped slide bar 2 , and the roller stop assemblies 303 are slidably connected to the arc-shaped slide bar 2 .

[0067] In this embodiment, each roller limiting assembly 303 is composed of two limiting wheels and a rolling rod. The rolling rod is fixedly inserted between the two limiting wheels. The rolling rod is located on the arc slide 2, and the two limiting wheels are clamped on both sides of the arc slide 2 to ensure that the rolling rod will not detach from the arc slide 2.

[0068] The first driving device 301 is fixed on one side of the fixed plate 302, and the output end of the first driving device 301 is transmission-connected to the arc-shaped slide bar 2. The setting of the fixed plate 302 can support the first driving device 301 to stabilize the first driving device 301.

[0069] Each arc-shaped slide bar 2 is fixed with an arc-shaped rack 13 extending along the arc-shaped slide bar 2. The output end of the first driving device 301 is fixedly connected to the first gear 14 through the fixed plate 302. When the first driving device 301 is started, it can drive the first gear 14 to rotate, and the first gear 14 and the arc-shaped rack 13 are meshed with each other.

[0070] In this embodiment, since the roller limiting assembly 303 clamps the fixed plate 302 on one side of the arc-shaped slide bar 2, the fixed plate 302 can be moved under the engagement of the first gear 14 and the arc-shaped rack 13 to drive the slide plate 9 to slide along the direction in which the arc-shaped slide bar 2 extends.

[0071] The first gear 14 cooperates with the arc-shaped rack 13 to enable the fixing plate 302 to move along the arc-shaped slide bar 2 .

[0072] In order to facilitate the movement of the shell 6 to different positions, in this embodiment, a second driving mechanism 10 that can move along the slide plate 9 is provided on the slide plate 9, and the shell 6 is connected to the second driving mechanism 10 in transmission to achieve the reciprocating movement of the shell 6 along the slide plate 9 under the action of the second driving mechanism 10. The second driving mechanism 10 is driven to start, so that the second driving mechanism 10 can drive the shell 6 to move along the direction in which the slide plate 9 extends, thereby adjusting the position of the detection component 7 to detect different positions of the detection tunnel segment 1.

[0073] Specifically, the second driving mechanism 10 includes a second driving device 1001 and a first lead screw 1002 extending along the extension direction of the tunnel segment 1. In this embodiment, the second driving device 1001 is a second driving servo motor, and the second driving device 1001 is fixed above the slide plate 9.

[0074] Two vertical plates are fixedly provided at the bottom of the slide plate 9, and the first lead screw 1002 is rotatably provided between the two vertical plates. The first lead screw 1002 is transmission-connected with the second driving device 1001 to rotate the first lead screw 1002.

[0075] A moving block 15 is mounted on the first lead screw 1002, and the moving block 15 is threadedly connected to the first lead screw 1002. The shell 6 is fixedly arranged at the lower end of the moving block 15, so that when the moving block 15 moves along the first lead screw 1002, the shell 6 will also move with the moving block 15. When the first lead screw 1002 rotates, since the moving block 15 is threadedly connected to the first lead screw 1002, it can drive the moving block 15 to move in the direction in which the slide plate 9 extends.

[0076] The output end of the second driving device 1001 is fixedly sleeved with a first sprocket 19, the slide plate 9 is provided with a through hole which is transparent from top to bottom, and the first lead screw 1002 is fixedly sleeved with a second sprocket 16, which drives the second driving device 1001 to start, so that the output end of the second driving device 1001 can drive the first sprocket 19 to rotate.

[0077] The first sprocket 19 is meshed with a chain 17, which passes through a through hole and is wound around the second sprocket 16, and meshes with the chain 17 and the second sprocket 16. The arrangement of the chain 17 can drive the second sprocket 16 to rotate. Since the second sprocket 16 is fixedly sleeved on the first lead screw 1002, the first lead screw 1002 can be driven to rotate.

[0078] The slide plate 9 is provided with a plurality of limit grooves 18 which are arranged at intervals on the left and right and extend along the tunnel segment 1. The setting of the limit grooves 18 can limit the moving block 15 and prevent the moving block 15 from tilting or deviating during the sliding process.

[0079] A plurality of limit blocks extending along the tunnel segment 1 are fixedly provided on the moving block 15. The limit blocks are slidably inserted into the limit grooves 18 to limit the moving block 15. Both the limit grooves 18 and the limit blocks are convex structures, so that they can not only slide but also play a limiting role.
