Technical Field
[0001] This utility model relates to the field of tunnel firefighting, and in particular to a portable barrier for tunnel firefighting. Background Technology
[0002] Tunnel firefighting refers to a series of firefighting and rescue operations carried out in response to fire accidents occurring inside tunnels.
[0003] Currently, Chinese patent CN210948794U discloses a tunnel fire door and a tunnel fire protection system. In a static state, the rotatable blades rotate to return to the closed door state. A unidirectional airflow acts on the door, and the airflow acts on the rotatable blades, causing them to rotate at a certain angle, forming an airflow channel between the rotatable blades that can maintain the air pressure balance between the inside and outside of the door. This prevents the door from deforming or loosening after being subjected to air pressure for a long time, and even prevents it from being easily carried into the driving lane H by the airflow in accidental circumstances, which could pose a certain safety hazard to vehicles and occupants.
[0004] After conducting a search of existing tunnel firefighting operations, the applicant found that: in some existing tunnel firefighting operations, firefighters use water hoses to extinguish the fire. Because the tunnel space is relatively enclosed, heat accumulates when a fire occurs and is difficult to dissipate. Even if firefighters are wearing protective clothing, the protective performance will gradually decrease if they are close to the fire for a long time. High temperatures may still penetrate the protective equipment, causing discomfort or even burns to the body. There is also a risk of explosion that could injure firefighters. Utility Model Content
[0005] The main purpose of this utility model is to provide a portable barrier for firefighting in tunnels, which aims to solve the problem that in some existing firefighting operations inside tunnels, firefighters use water guns to extinguish the fire. Because the tunnel space is relatively closed, heat accumulates when a fire occurs and is difficult to dissipate. Even if firefighters are wearing protective clothing, the protective performance will gradually decrease if they are close to the fire for a long time. High temperatures may still penetrate the protective equipment, causing discomfort or even burns to the body. There is also a risk of explosion that could injure firefighters.
[0006] To achieve the above objectives, the present invention proposes a portable partition for tunnel firefighting, which includes a first partition plate, a protective mechanism on the top of the first partition plate, and casters on the front and rear sides of the bottom of the first partition plate.
[0007] The protective mechanism includes two protective felts, explosion-proof glass, a second baffle plate, and a through hole. The front side of the top protective felt is fixedly connected to the rear side of the second baffle plate. The through hole is opened inside the second baffle plate. The explosion-proof glass is fixedly connected to the inner wall of the through hole. The front side of the bottom protective felt is fixedly connected to the rear side of the first baffle plate. Both the first baffle plate and the second baffle plate are made of lightweight puncture-resistant material.
[0008] Preferably, the second baffle plate has a fire extinguishing hole inside, and an anti-slip pad is fixedly connected to the inner wall of the fire extinguishing hole. The protective felt is made of aluminum silicate fiber.
[0009] Preferably, brackets are provided on both sides of the bottom of the first partition plate, and the casters are rotatably connected to the bottom of the brackets.
[0010] Preferably, the bottom of the bracket is provided with a fixed shaft, the top of the fixed shaft passes through the bracket and is fixedly connected to the bottom of the first partition plate, and the surface of the fixed shaft is in movable contact with the interior of the bracket.
[0011] Preferably, magnets for use with the bracket are embedded on both sides of the bottom of the first partition plate, and there is damping at the movable connection between the fixed shaft and the bracket.
[0012] Preferably, hinges are provided on both sides of the top rear side of the first partition plate, and the rotatable connection between the first partition plate and the second partition plate is rotatably connected by the hinges.
[0013] Preferably, both sides of the front of the first and second partitions are fixedly connected with locking blocks, and magnetic plates are movably engaged between the interiors of adjacent locking blocks.
[0014] Preferably, handles are fixedly connected to both sides of the front side of the first partition, and pull rings are fixedly connected to the surface of the magnetic plate.
[0015] In this invention, when a fire occurs in a tunnel, rescuers can quickly push a portable partition towards the fire scene. The casters allow the partition to move flexibly within the tunnel, facilitating rapid position adjustments by rescuers. Simultaneously, damping exists between the bracket and the fixed shaft, ensuring stability of the casters during movement and preventing uncontrolled swaying. Since both the first and second partitions are made of lightweight, puncture-resistant materials, they can withstand impacts from flying debris at the fire scene, protecting the safety of rescuers. The explosion-proof glass on the second partition not only effectively blocks flames and high-temperature radiation but also allows rescuers to observe the fire scene without obstructing their view. The protective felt is made of aluminum silicate fiber, possessing excellent fireproof and heat insulation properties, further protecting the safety of rescuers. The fire extinguishing holes inside the second partition allow for the insertion of fire hoses, and the anti-slip pads on the inner walls of the fire extinguishing holes increase friction with the fire hoses. This design makes the partition more stable, facilitating firefighting operations behind the barrier and reducing the risk of direct exposure to danger for rescuers. After using the first and second partitions, the magnetic plate can be pulled out from between the two clips to easily rotate and fold the second partition backward for storage. Then, the bracket can be rotated until it is magnetically attracted to the magnet to fold it, making it easy to stack and store the first and second partitions. This also facilitates carrying the first and second partitions, avoiding the current practice in some tunnels where firefighters use water hoses to extinguish fires. Because tunnel spaces are relatively enclosed, heat accumulates during a fire and is difficult to dissipate. Even if firefighters wear protective clothing, prolonged proximity to the fire will gradually reduce the protective performance, and high temperatures may still penetrate the protective equipment, causing discomfort or even burns. There is also the risk of explosions that could injure firefighters. Attached Figure Description

[0028] This utility model provides a portable barrier for firefighting in tunnels, aiming to solve the problem that in some existing firefighting operations inside tunnels, firefighters use water guns to extinguish the fire. Due to the relatively enclosed space of the tunnel, heat accumulates when a fire occurs and is difficult to dissipate. Even if firefighters are wearing protective clothing, the protective performance will gradually decrease if they are close to the fire for a long time. High temperatures may still penetrate the protective equipment, causing discomfort or even burns to the body. There is also a risk of explosion that could injure firefighters.
[0029] like Figure 1-5 As shown in the figure, a portable partition for tunnel firefighting provided by this utility model embodiment includes a first partition plate 1, a protective mechanism 2 is provided on the top of the first partition plate 1, and casters 12 are provided on the front and rear sides of the bottom of the first partition plate 1.
[0030] The protective mechanism 2 includes two protective felts 201, explosion-proof glass 202, a second baffle 203, and a through hole 204. The front side of the top protective felt 201 is fixedly connected to the rear side of the second baffle 203. The through hole 204 is opened inside the second baffle 203. The explosion-proof glass 202 is fixedly connected to the inner wall of the through hole 204. The front side of the bottom protective felt 201 is fixedly connected to the rear side of the first baffle 1. Both the first baffle 1 and the second baffle 203 are made of lightweight puncture-resistant material.
[0031] In the technical solution of this utility model, when a fire occurs in a tunnel, rescuers can quickly push the portable partition to the fire scene. The casters 12 allow the partition to move flexibly within the tunnel, facilitating quick position adjustments for rescuers. Simultaneously, damping exists between the bracket 4 and the fixed shaft 13, ensuring the casters 12 remain stable during movement and preventing erratic swaying. Since both the first partition 1 and the second partition 203 are made of lightweight, puncture-resistant material, they can withstand impacts from flying debris at the fire scene, protecting the safety of rescuers. The explosion-proof glass 202 on the second partition 203 not only effectively blocks flames and high-temperature radiation but also allows rescuers to observe the fire scene without obstructing their view. The protective felt 201, made of aluminum silicate fiber, has excellent fireproof and heat insulation properties, further protecting the safety of rescuers. The fire extinguishing hole 5 inside the second partition 203 can be used to insert a fire hose, and the anti-slip pad 6 on the inner wall of the fire extinguishing hole 5 increases the slip resistance with the fire hose. The friction makes it more stable, making it easier for rescuers to carry out firefighting operations behind the barrier, reducing the risk of rescuers being directly exposed to danger. After using the first barrier 1 and the second barrier 203, the magnetic plate 9 can be pulled out from between the two clips 3, making it easy to rotate and fold the second barrier 203 backward for storage. Then, the bracket 4 can be rotated until it is magnetically attracted to the magnet 8, making it easy to fold the bracket 4, making it easy to stack and store the first barrier 1 and the second barrier 203. This makes it easy to carry the first barrier 1 and the second barrier 203. This avoids the problem that in some existing tunnel firefighting operations, firefighters use water guns to extinguish the fire. Because the tunnel space is relatively closed, heat accumulates when a fire occurs and is difficult to dissipate. Even if firefighters wear protective clothing, the protective performance will gradually decrease if they are close to the fire for a long time. High temperatures may still penetrate the protective equipment, causing discomfort or even burns to the body, and there is also the risk of explosion that could injure firefighters.
[0032] Please refer to the following: Figure 2 The second partition 203 has a fire extinguishing hole 5 inside, and an anti-slip pad 6 is fixedly connected to the inner wall of the fire extinguishing hole 5. The protective felt 201 is made of aluminum silicate fiber. In this embodiment, the fire can be extinguished by inserting a fire hose into the fire extinguishing hole 5. The anti-slip pad 6 can stably support the fire hose, and the protective felt 201 made of aluminum silicate fiber has good fireproof and heat insulation properties, protecting the safety of rescue personnel.
[0033] For further information, please continue to refer to [link / reference]. Figure 1 and Figure 4 The first partition 1 has brackets 4 on both sides of its bottom, and casters 12 are rotatably connected to the bottom of the brackets 4. In this embodiment, the first partition 1 and the second partition 203 can be easily moved by the casters 12 rotatably connected to the bottom of the brackets 4.
[0034] Please continue to refer to this. Figure 1 and Figure 4 The bottom of the bracket 4 is provided with a fixed shaft 13, the top of the fixed shaft 13 passes through the bracket 4 and is fixedly connected to the bottom of the first partition plate 1, and the surface of the fixed shaft 13 is in movable contact with the interior of the bracket 4. In this embodiment, by having the top of the fixed shaft 13 pass through the bracket 4 and be fixedly connected to the top of the first partition plate 1, the bracket 4 can be rotated and folded for storage.
[0035] Please refer to Figure 1 and Figure 4 Magnets 8, which cooperate with the bracket 4, are embedded on both sides of the bottom of the first partition plate 1. There is damping at the movable connection between the fixed shaft 13 and the bracket 4. In this embodiment, because there is damping at the movable connection between the fixed shaft 13 and the bracket 4, the bracket 4 can be limited to any position, preventing the bracket 4 from rotating arbitrarily.
[0036] Additionally, please refer to Figure 3 Hinges 11 are provided on both sides of the top rear side of the first partition 1, and the first partition 1 and the second partition 203 are rotatably connected by the hinges 11. In this embodiment, the first partition 1 and the second partition 203 are rotatably connected by the hinges 11, so that the second partition 203 can be folded backward for easy carrying.
[0037] Please refer to Figure 1 , Figure 2 and Figure 3 Both sides of the front of the first partition plate 1 and the second partition plate 203 are fixedly connected to locking blocks 3, and magnetic suction plates 9 are movably engaged between the interiors of adjacent locking blocks 3. In this embodiment, by rotating the second partition plate 203 upwards and opening it, the magnetic suction plate 9 is inserted between the opposite sides of the two locking blocks 3, which can limit the first partition plate 1 and the second partition plate 203 together and prevent rotation. The magnetic attraction between the magnetic suction plate 9 and the locking blocks 3 can prevent the magnetic suction plate 9 from detaching from the locking blocks 3.
[0038] Additionally, please refer to Figure 2 Handles 7 are fixedly connected to both sides of the front side of the first partition 1, and pull rings 10 are fixedly connected to the surface of the magnetic plate 9. In this embodiment, the first partition 1 and the second partition 203 can be easily moved by holding the handles 7, and the magnetic plate 9 can be easily pulled by holding the pull rings 10.
[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
