Description
Technical Field
[0001] The utility model relates to the technical field of tunnel ventilation, in particular to a tunnel smoke exhaust device. Background Art
[0002] In tunnel construction, smoke exhaust devices are crucial to ensure air quality and safety in tunnels. Traditionally, tunnel smoke exhaust devices mainly rely on a combination of fans and smoke exhaust ducts to remove smoke. However, these traditional methods have shortcomings such as low smoke exhaust efficiency, long response time, and high installation and maintenance costs when dealing with emergencies such as sudden fires. In addition, under extreme weather conditions, the performance of traditional smoke exhaust systems may be severely affected and cannot effectively meet the needs of smoke removal in tunnels.
[0003] A Chinese patent with publication number CN219910835U discloses a smoke exhaust device for a tunnel, which includes a mounting body, a fan assembly and a smoke exhaust assembly. A smoke push duct and a smoke collecting duct are provided on the mounting body, and a smoke outlet is provided at either end of the smoke push duct; a partition wall is provided on the mounting body to separate the smoke push duct and the smoke collecting duct, and a smoke outlet is provided on the partition wall; the fan assembly is provided at the smoke outlet; the smoke exhaust assembly is provided at the smoke outlet, and when the smoke exhaust assembly is in a smoke exhaust working condition, the smoke outlet is opened. In the smoke exhaust device for a tunnel described in the utility model, the fan assembly is used for ventilation inside the tunnel from the outside, and at the same time, the fan assembly can push the smoke in the smoke push duct to the outside of the tunnel; when the smoke inside the tunnel is too much, the smoke exhaust assembly is in a smoke exhaust working condition, thereby opening the smoke outlet, allowing the smoke in the smoke collecting duct to enter the smoke push duct, and then the smoke is pushed out of the tunnel by the fan assembly.
[0004] Based on the above search and combined with the prior art, we found that:
[0005] A smoke push duct and a smoke collecting duct are arranged on the installation body of the existing device, and a smoke outlet is arranged at either end of the smoke push duct; a partition wall is arranged on the installation body to separate the smoke push duct and the smoke collecting duct, and a smoke outlet is arranged on the partition wall. Smoke appears in the tunnel mostly because of a fire somewhere. When the fire just starts, the smoke here is large and spreads to the surroundings. The position of the smoke outlet of the existing device is fixed, and the smoke exhaust effect is relatively scattered. It is impossible to exhaust the smoke in the area with large smoke in time, which causes the smoke to spread quickly to various places in the tunnel. The smoke exhaust efficiency is too low, and there are limitations during use. Utility Model Content

[0036] like Figure 1-Figure 4 As shown, this embodiment provides a tunnel smoke exhaust device, which is used in conjunction with a tunnel wall 1. The tunnel smoke exhaust device includes a support frame 2 for installation on the tunnel wall 1. The support frame 2 is provided with a plurality of bolts 3, which are respectively arranged at the corners of the support frame 2. The support frame 2 is fixed to the tunnel wall 1 by the plurality of bolts 3. A first slide groove 4 is provided on the support frame 2, and a plurality of electric sliders 5 are slidably connected to the first slide groove 4. Each electric slider 5 is fixedly connected to a connecting column 6, and a smoking box 7 is fixedly connected to the end of the connecting column 6 away from the electric slider.
[0037] Furthermore, a negative pressure fan 8 is fixedly installed on the smoking box 7, a connecting block 9 is fixedly connected to the bottom of the smoking box 7, a second slide groove 10 is provided on the support frame 2, the connecting block 9 is slidably connected to the second slide groove 10, an opening is provided on the smoking box 7, an activated carbon box 11 is placed in the opening, the activated carbon box 11 is movably connected to the opening, and the activated carbon box 11 can be pulled out from the opening, so as to facilitate replacement.
[0038] Furthermore, each smoking box 7 is connected to a smoke hose 12, a strip hole 13 is provided on the support frame 2, the length direction of the strip hole 13 is the same as the extension direction of the first chute, a smoke collecting box 14 is fixedly installed on the tunnel wall 1, a tunnel top layer 15 is fixedly connected to the tunnel wall 1, the smoke collecting box 14 is connected to the tunnel top layer 15, the smoke hose 12 on the smoking box is passed through the strip hole 13, and is connected to the smoke collecting box 14. A smoke exhaust port 16 is provided on the tunnel top layer 15, the smoke exhaust port 16 is connected to the smoke collecting box 14, and a protective net 17 is fixedly installed on the smoke exhaust port 16.
[0039] With such a design, the tunnel smoke exhaust device in this embodiment installs the support frame 2 on the tunnel wall 1, and a first slide groove 4 is provided on the tunnel wall 1. The electric slider 5 can slide on the first slide groove 4. Each electric slider can be independently controlled to control the position of the corresponding cigarette box. That is, when the electric slider slides in the first slide groove, the cigarette box 7 connected to the electric slider 5 through the connecting column 6 can also be driven to move on the support frame 2. The connecting block 9 connected to the bottom of the cigarette box 7 slides on the second slide groove 10 to ensure the stability of the cigarette box 7 when moving.

In the tunnel smoke exhaust device provided in this embodiment, a pair of water outlet pipes 18 are connected to the water inlet pipe 20 through the connector 19, and water can be supplied to the plurality of water sprinklers 21. When smoke is generated, water is sprayed by the plurality of water sprinklers 21, so that harmful particles in the smoke can be settled to prevent harmful substances from floating in the air and causing danger.
[0043] In addition, each water spray head can be set to a swing structure, which can adjust the angle when spraying water, thereby expanding the treatment range. The swing structure of the water spray head can refer to the existing known structure, and this embodiment will not be described in detail.
[0044] The working process of the tunnel smoke exhaust device provided in this embodiment is as follows:
[0045] The tunnel smoke exhaust device provided in this embodiment installs the support frame 2 on the tunnel wall 1, and a first slide groove 4 is opened on the tunnel wall 1. The electric slider 5 can slide on the first slide groove 4, and the smoking box 7 connected to the electric slider 5 through the connecting column 6 can also be driven to move on the support frame 2. The connecting block 9 connected to the bottom of the smoking box 7 slides on the second slide groove 10 to ensure the stability of the smoking box 7 when moving. The negative pressure fan 8 installed on the smoking box 7 can inhale the smoke, and the smoke is filtered through the activated carbon box 11 to prevent impurities in the smoke from clogging the smoke outlet hose 12. The activated carbon box 11 can be withdrawn and replaced to ensure the filtering effect. After the smoke is filtered, it enters the smoke collecting box 14 through the smoke outlet hose 12 , and then discharged from the smoke exhaust port 16 on the top layer 15 of the tunnel. A protective net 17 is installed on the smoke exhaust port 16 to prevent foreign objects from entering and causing blockage. When encountering a place with heavy smoke, the smoke exhaust effect of a single smoking box 7 is poor. The electric slider 5 drives other smoking boxes 7 to move to the location with heavy smoke, so as to achieve the effect of smoking in a concentrated manner in multiple smoking boxes 7, and the smoke exhaust efficiency is high. Harmful substances in the smoke float in the air together. A pair of water outlet pipes 18 of the device are connected to the water inlet pipe 20 through a connector 19, and water can be supplied to multiple water sprinklers 21. When smoke is generated, water is sprayed by multiple water sprinklers 21, which can settle harmful particles in the smoke and prevent harmful substances from floating in the air and causing danger.
