Description

Technical Field

[0001] This utility model relates to the field of gas elimination technology, and more specifically, to a gas elimination device for tunnel construction. Background Technology

[0002] During tunnel construction, the complexity of geological conditions and the disturbance caused by construction activities often generate harmful gases such as methane. The accumulation of these gases not only threatens the lives of construction workers but may also trigger serious accidents such as explosions. Therefore, methane removal during tunnel construction is a crucial step in ensuring the safe and smooth progress of the project. Traditional methane removal methods mostly rely on ventilation, which, while diluting the methane concentration to some extent, is inefficient and has limited effectiveness in areas with high methane concentrations. To improve the efficiency and effectiveness of methane removal, devices utilizing adsorption materials, such as activated carbon, for methane purification have gradually emerged on the market.

[0003] However, existing gas elimination devices present numerous inconveniences in the installation and replacement of activated carbon mesh. Typically, the installation process is cumbersome, requiring tools for screw fixing or bolt connection. This not only increases installation time but can also lead to poor sealing due to improper operation, affecting the purification effect. Furthermore, the adsorption capacity of activated carbon gradually decreases after prolonged use, necessitating regular replacement to maintain purification efficiency. However, replacing the activated carbon mesh in existing devices is often time-consuming and labor-intensive, requiring the disassembly of numerous fasteners, which not only affects construction efficiency but also increases maintenance costs. Therefore, to address these technical problems, a gas elimination device for tunnel construction is proposed. Utility Model Content

Through a cleverly designed installation plate and partition connection mechanism, the activated carbon mesh can be quickly installed and easily replaced, ensuring that the gas elimination device can continuously maintain a high gas elimination capacity, effectively improving the safety and efficiency of tunnel construction.

An air inlet is provided on the upper side of the device body. An installation cylinder is fixedly connected to the top of the air inlet. A dustproof net is provided on one side of the installation cylinder. A flow guiding mechanism is installed on the inner side of the installation cylinder.

[0007] A partition is fixedly connected to the inner side of the main body of the device, and the partition is located near the open side of the main body of the device. An opening is opened on the outside of the partition. An activated carbon mesh is opened on the outside of the mounting plate. A slot is opened on the outside of the partition. An installation groove is opened on the inside of the slot, and the slot and the installation groove are perpendicular to each other. A wedge block is slidably connected to the inside of the installation groove, and the end of the wedge block is located inside the slot. A spring is fixedly connected to the inside of the installation groove, and the end of the spring is fixedly connected to one side of the wedge block. A plug rod is fixedly connected to one side of the mounting plate. A locking hole is opened on the outside of the plug rod, and the locking hole matches the wedge block. A synchronous tensioning mechanism is installed on the inside of the main body of the device.

[0008] Preferably, a walking device is fixedly connected to the bottom of the main body of the device.

[0009] Preferably, the flow guiding mechanism includes a fixed rod and a fan, the fixed rod being fixedly connected to the inner side of the mounting cylinder, and the fan being fixedly connected to the outer side of the fixed rod.

[0010] Preferably, the activated carbon mesh is a mesh-like perforated structure made of activated carbon material.

[0011] Preferably, the insertion rod and the slot are matched, and the insertion rod and the slot are respectively installed at the four corners of the mounting plate and the partition.

[0012] Preferably, the synchronous tensioning mechanism includes a rotating rod and a connecting rope.

[0013] Preferably, the rotating rod has a screw fixedly connected to one end protruding from the outer side of the device body.

[0014] The technical solution of this utility model has at least the following beneficial effects:

[0015] This utility model proposes a gas elimination device for tunnel construction. Because the mounting plate is equipped with an activated carbon mesh, and the four corner rods match the slots on the partition plate, the rods automatically compress spring-driven wedges during insertion until the wedges are locked into the slots by the spring force, achieving stable positioning. This process requires no additional tools, greatly simplifying the installation steps. When the activated carbon mesh becomes saturated and the purification effect weakens, simply rotating the external screw of the device drives the rotating rod to wind the connecting rope, causing the wedges to retract synchronously and disengage from the slots, thus easily removing the mounting plate and activated carbon mesh. The entire process is quick and simple, ensuring that the gas elimination device can continuously maintain a high efficiency in gas elimination, effectively improving the safety and efficiency of tunnel construction.

[0027] A partition 8 is fixedly connected to the inner side of the main body 1 of the device, and the partition 8 is located on the open side near the main body 1 of the device. An opening 9 is opened on the outside of the partition 8. An activated carbon mesh 11 is opened on the outside of the mounting plate 10. A slot 12 is opened on the outside of the partition 8. An installation groove 13 is opened on the inside of the slot 12. The slot 12 and the installation groove 13 are perpendicular to each other. A wedge block 14 is slidably connected to the inside of the installation groove 13. The end of the wedge block 14 is located inside the slot 12. A spring 15 is fixedly connected to the inside of the installation groove 13. The end of the spring 15 is fixedly connected to one side of the wedge block 14. A rod 16 is fixedly connected to one side of the mounting plate 10. A locking hole 17 is opened on the outside of the rod 16. The locking hole 17 matches the wedge block 14. A synchronous tensioning mechanism is installed on the inside of the main body 1 of the device.

[0028] The bottom of the main body 1 is fixedly connected to a walking device 2. The walking device 2 is set to facilitate the movement of this device in the tunnel and to dynamically remove gas in the tunnel.

[0029] The flow guiding mechanism includes a fixed rod 6 and a fan 7. The fixed rod 6 is fixedly connected to the inside of the mounting cylinder 4, and the fan 7 is fixedly connected to the outside of the fixed rod 6. The activated carbon mesh 11 is a mesh-like hollow structure made of activated carbon material.

[0030] The insertion rod 16 and the slot 12 are matched, and the insertion rod 16 and the slot 12 are respectively installed at the four corners of the mounting plate 10 and the partition plate 8, which facilitates the stable installation of the mounting plate 10.

[0031] The synchronous tensioning mechanism includes a rotating rod 18 and a connecting rope 19. The rotating rod 18 is rotatably connected to the inner side of the device body 1 and one end protrudes from the outside of the device body 1. The rotating rod 18 is located at the center of the partition 8 in the vertical direction. The connecting rope 19 is fixedly connected to the upper and lower sides of the rotating rod 18. The end of the connecting rope 19 passes through the partition 8 and the mounting groove 13 and is fixedly connected to one side of the wedge block 14. The spring 15 is sleeved on the outside of the connecting rope 19.

[0032] The rotating rod 18 protrudes from the outer side of the main body 1 and is fixedly connected to a screw 20. The screw 20 is provided to facilitate the control of the rotation of the rotating rod 18.

[0033] The working principle of a gas elimination device for tunnel construction based on an embodiment is as follows: When using this device to eliminate gas in the air inside the tunnel, firstly, an installation plate 10 equipped with an activated carbon mesh 11 needs to be installed. The insertion rods 16 at the four corners of one side of the installation plate 10 are aligned with the slots 12 on one side of the partition plate 8. The insertion rods 16 are inserted straight into the slots 12, allowing them to contact the wedge block 14. Since one side of the wedge block 14 is inclined, when the insertion rod 16 applies pressure to the inclined surface, it causes the wedge block 14 to retract into the installation groove 13 and compress the spring 15, allowing the insertion rod 16 to continue inserting until the wedge block 14 aligns with the locking hole 17. Then, under the elastic force of the spring 15, the wedge block 14 automatically locks into the locking hole 17, thus completing the positioning of the insertion rod 16 and the rapid installation of the activated carbon mesh 11. Next, only the blower 7 needs to be operated to... Air from inside the tunnel is guided through the air inlet 3 into the main body 1 of the device via the mounting cylinder 4. Upon contact with the activated carbon mesh 11, the gas molecules are firmly fixed inside the activated carbon due to its rich microporous structure and intermolecular forces, thus eliminating gas in the tunnel air to a certain extent. When the activated carbon mesh 11's gas-eliminating ability decreases after a period of use, simply rotating the screw 20 on the outside of the main body 1 will rotate the rotating rod 18, causing it to simultaneously wind all the connecting ropes 19. The ends of the connecting ropes 19 will then cause all the wedge blocks 14 to retract synchronously into the mounting groove 13 and be pulled out through the locking hole 17, easily disassembling the mounting plate 10. This achieves the effect of quick and easy replacement of the activated carbon mesh 11, ensuring the device maintains its ability to eliminate gas in the tunnel air.
