Description

Technical Field

[0002] Tunnels are crucial components of subways, high-speed railways, and highways. Thorough preparation is essential for tunnel breakthrough to ensure project safety. During tunnel construction, the limited space at the tunnel entrance and poor air circulation, coupled with the generation of dust, engine exhaust, and even blasting fumes during construction, all contribute to the accumulation of harmful substances within the tunnel entrance, seriously impacting the health of workers inside. Therefore, during tunnel construction, it is necessary to expel dust, exhaust fumes, and blasting fumes from the tunnel entrance while simultaneously supplying fresh air into the tunnel to ensure the safety of workers during the tunnel breakthrough process.

[0003] To address the above issues, Chinese patent application CN114995272A discloses an intelligent centralized control system and method for blasting ventilation in tunnel construction. This system includes a monitoring unit and a first programmable logic controller (PLC), both located on the blasting equipment. The monitoring unit is communicatively connected to the first PLC and can collect environmental data from the tunnel blasting operation, sending it to the first PLC. The first PLC judges the environmental data based on a preset logical relationship. In response to the environmental data satisfying the preset logical relationship, the first PLC issues a control command. A second PLC is located at the tunnel entrance and is communicatively connected to the first PLC, controlling the ventilation unit to operate at a variable frequency according to the received control command. The ventilation units are installed inside the tunnel and are all communicatively connected to the second PLC, thereby achieving high-precision unmanned control of tunnel construction.

[0029] Example 1:

[0030] like Figures 1 to 3 As shown, a smart control platform for tunnel breakthrough construction safety includes: a work platform 1, an exhaust assembly 2, and a walking assembly 3; a control system is installed on the work platform 1; the work platform 1 is located outside the tunnel entrance; the exhaust assembly 2 includes an intake duct 21, an exhaust duct 22, and a fan 23; the intake end of the fan 23 is connected to one end of the intake duct 21, and its exhaust end is connected to one end of the exhaust duct 22; the intake duct 21 is a flexible hose; the fan 23 is connected to the control system circuit; the walking assembly 3 includes a walking platform 31 and a monitoring unit 32; the monitoring unit 32 is installed on the walking platform 31 and moves with the walking platform 31; the monitoring unit 32 includes a dust sensor and a hazardous gas sensor, wherein the hazardous gas sensor includes a methane transmitter and a carbon dioxide transmitter to monitor the dust, methane, and carbon dioxide levels inside the tunnel in real time; the walking platform 31 and the monitoring unit 32 are connected to the control system circuit; the end of the intake duct 21 away from the fan 23 is connected to the walking platform 31, and this end moves together with the walking platform 31. Additionally, it should be noted that the connection method between the control system and the fan, the traveling platform, and the monitoring unit is a conventional connection. The specific models of the control system, the fan, and the monitoring unit are not improvements in this application and will not be elaborated here.

[0031] Work style:

[0032] In use, the walking platform 31, exhaust duct 22, and workbench 1 are placed outside the opening. The walking platform 31 is controlled by the control system to move forward into the opening. One end of the exhaust duct 22 is also moved into the opening by the walking platform 31. The monitoring unit 32 is activated to monitor the environment inside the opening, detecting the presence of dust, methane, carbon dioxide, etc. Once the concentrations of dust, methane, and carbon dioxide reach preset values, the control system activates the fan 23. The suction duct 21, connected to the suction end of the fan 23, begins to draw in air, removing the dust, methane, and carbon dioxide from the opening. Dust, methane, and carbon dioxide are drawn in by the suction duct 21, passed through the fan 23, and finally discharged from the exhaust duct 22, removing dust, methane, and carbon dioxide from the tunnel entrance until their concentrations are reduced to preset values ​​to ensure the air environment inside the tunnel and protect the health of the workers. As the length of the tunnel increases, the control system controls the traveling platform 31 to move forward a certain distance into the tunnel to monitor the dust, methane, and carbon dioxide levels ahead. This process is repeated to adapt to the increase in tunnel length and achieve safe construction control during tunnel breakthrough.

[0033] Example 2:

[0034] like Figures 3 to 5 As shown, compared with Embodiment 1, the difference lies in the structural form of the traveling platform 31 provided. The traveling platform 31 includes a traveling component 311, a first plate 312, a first motor 313, and a frame 314. The two sides of the frame 314 are connected to the traveling component 311. Preferably, the traveling component 311 is a tracked structure to adapt to the on-site construction environment. The tracked structure includes a traveling wheel and a track. The traveling wheel is rotatably connected to the frame 314, and the track covers the traveling wheel. The first motor 313 is mounted on the frame 314, and its output end is connected to the traveling component 311, that is, the first motor 313 is connected to the traveling wheel and drives the traveling wheel to rotate. Preferably, there are two first motors 313, located diagonally opposite each other on the frame 314 to facilitate the turning of the frame 314. The first plate 312 is mounted on the top surface of the frame 314. The monitoring unit is mounted on the first plate 312. The first motor 313 is connected to the control system circuit, and the control system controls the first motor 313. Additionally, it should be noted that the connection between the first motor and the control system is a conventional connection, and the specific model of the first motor is not an improvement point of this application, so it will not be elaborated here.

[0035] like Figures 3 to 5 As shown, preferably, the walking platform 31 further includes a second plate 315 and a rod 316; one end of the second plate 315 is vertically connected to the first plate 312, and the other end is connected to the rod 316; the rod 316 is detachably connected to the suction pipe 21, and the ends of the rod 316 and the suction pipe 21 can be tied together by ropes or the like to achieve a detachable connection, and the overall structure is simple.

[0036] like Figures 3 to 5 As shown, preferably, the walking platform 31 further includes a rotating wheel 317 and a second motor 318; the rotating wheel 317 is rotatably disposed at the end of the second plate 315 away from the first plate 312; the axis of the rotating wheel 317 is horizontally distributed; the rod 316 is rotatably disposed on the second plate 315 via the rotating wheel 317; one end of the rod 316 is connected to the side of the rotating wheel 317, and the rod 316 rotates when the rotating wheel 317 rotates; the second motor 318 is disposed on the second plate 315, and its output end is connected to a rotating mechanical transmission; the second motor 318 is disposed on the second plate 315, and its output end is connected to a rotating mechanical transmission. The second motor 318 is connected to the control system circuit. Optionally, the second motor 318 and the rotating wheel 317 are connected via belt drive. When it is necessary to change the angle of the suction duct 21, the control system controls the second motor 318 to start. The second motor 318 rotates and drives the rotating wheel 317 to rotate at a certain angle. The rod 316 rotates at a certain angle with the rotating wheel 317, changing the original tilt angle. It can tilt upwards, downwards, or be horizontally distributed. The suction duct 21 rotates with the rod 316, thereby achieving multi-angle suction. In addition, it should be noted that the connection method between the second motor and the control system is a conventional connection. The specific model of the second motor is not an improvement point of this application and will not be described here.

[0037] like Figures 3 to 5 As shown, preferably, this application also includes a ranging radar 319; the ranging radar 319 is disposed at the front end of the vehicle frame 314, and its detection end is consistent with the traveling direction of the vehicle frame 314; the ranging radar 319 is connected to the control system circuit; the ranging radar 319 can be a laser ranging radar, ultrasonic ranging radar, or millimeter-wave radar, etc., and the ranging radar 319 faces the side of the tunnel to be opened, detecting the distance between the vehicle frame 314 and the tunnel surface to be opened. When the distance between the ranging radar 319 and the tunnel surface to be opened increases, the control system controls the first motor 313 to start, causing the ends of the vehicle frame 314 and the suction duct 21 to move forward, automatically shortening the distance between the vehicle frame 314 and the tunnel surface to be opened, so as to maintain the distance between the suction duct 21 and the tunnel surface to be opened, thereby realizing intelligent control. In addition, it should be noted that the connection method between the ranging radar and the control system is a conventional connection, and the specific model of the ranging radar is not an improvement point of this application, and will not be described in detail here.

[0038] Example 3:

[0039] like Figure 1 and Figure 2As shown, compared with Embodiment 1, the difference is that the exhaust assembly 2 also includes a first housing 24; the first housing 24 is filled with water; the end of the exhaust pipe 22 away from the fan 23 extends into the first housing 24 and communicates with the first housing 24; the top of the first housing 24 has a first opening to exhaust the air inside the first housing 24; dust, methane, carbon dioxide, etc. are discharged from the exhaust pipe 22 and enter the first housing 24, and come into contact with the water inside the first housing 24, so that the dust accumulates inside the first housing 24, avoiding a large amount of dust being discharged into the atmosphere and causing environmental pollution.

[0040] like Figure 1 and Figure 2 As shown, preferably, the exhaust duct 22 extends into one end of the first housing 24 without contacting the water inside the first housing 24. The exhaust assembly 2 also includes a second housing 25 and a connecting duct 26. The second housing 25 is filled with water. One end of the connecting duct 26 is connected to the first housing 24 through a first opening (this end does not contact the water inside the first housing 24), and the other end extends into the top of the second housing 25 and towards the bottom of the second housing 25, contacting the water in the second housing 25 (i.e., this end is submerged in water). A second opening is provided at the top of the second housing 25. The air in the second chamber 25 is discharged through the outlet; dust, methane, and carbon dioxide first enter the first chamber 24. Some of the dust comes into contact with the water in the first chamber 24 and accumulates there. The other part of the dust enters the second chamber 25 through the connecting pipe 26. Because one end of the connecting pipe 26 and the second chamber 25 is submerged in water, the dust discharged from the connecting pipe 26 comes into direct contact with the water in the second chamber 25 and cannot disperse. It accumulates in the second chamber 25, enhancing the purification of the dust. At the same time, the first chamber 24 acts as a buffer.

[0041] like Figure 1 and Figure 2 As shown, preferably, the exhaust assembly 2 also includes an activated carbon filter element 27; the activated carbon filter element 27 is disposed on the second opening. Since methane is poorly soluble in water, after the methane passes through the first chamber 24 and the second chamber 25, it is discharged from the second opening. The activated carbon filter element 27 absorbs the methane, preventing the methane from being discharged into the atmosphere and polluting the environment.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
