Description

Technical Field

[0001] The utility model relates to the technical field of tunnel ventilation and smoke exhaust, in particular to a partition intelligent lifting system based on a tunnel flat-guide ventilation and smoke exhaust mode. Background Art

[0002] Tunnel ventilation and smoke exhaust refers to the process of exhausting smoke, exhaust gas and pollutants from the tunnel through a reasonable ventilation system to ensure the air quality and safety in the tunnel. In the tunnel, vehicle exhaust, combustion substances and other emissions will produce a large amount of smoke and harmful gases. If these substances accumulate and concentrate in the tunnel, they will pose a serious threat to the safety of personnel and vehicles.

[0003] The main purpose of the smoke exhaust system is to maintain the air quality in the tunnel: by removing smoke and pollutants, the air in the tunnel is kept fresh to ensure the comfort and safety of drivers and passengers.

[0004] Reduce the spread of fire and smoke: In the event of a fire, the smoke exhaust system can effectively exhaust smoke from the tunnel, reduce the speed of fire spread, and increase the time window for evacuation.

[0005] Provide escape conditions: The smoke exhaust system can provide clear sight and relatively clean air environment for personnel evacuation, improving escape efficiency and safety.

[0006] However, as the length of national and provincial highway tunnels is developing towards the 10km level, the smoke spread length in the main tunnel when a fire occurs may exceed 5km, far exceeding the requirement of the specification that it should not be greater than 3km, which seriously threatens the safety of personnel, vehicles and equipment facilities in long-distance tunnels. The installation of a separate smoke exhaust duct will greatly increase the cost. The flat guide has a horseshoe-shaped cross-section (drilling and blasting method) or a circular cross-section (TBM method), and there is a certain amount of usable space on the top. It is only used as an air intake and emergency escape channel, which also makes the utilization rate of large-scale flat guides not high.

[0007] Therefore, in order to improve the ventilation and smoke exhaust efficiency of super-long highway tunnels, increase the utilization rate of flat guides, and reduce the comprehensive construction and operation costs, it is urgent to explore and study a new mode of coordinated control of flat guide ventilation and smoke exhaust, that is, to adopt efficient layered utilization of flat guides, use partitions to separate the upper and lower parts of the flat guide, with the lower part as the air intake and escape channel and the upper part as the smoke exhaust channel, and optimize the traditional flat guide air intake main tunnel smoke exhaust control mode to flat guide ventilation and smoke exhaust coordinated control.

[0008] Therefore, in order to be able to judge the fire situation when a fire occurs and realize automatic adjustment of the position of the horizontal channel and the horizontal guide partition, according to the needs of fire smoke exhaust or large-volume air supply, the partition position is automatically adjusted to change the effective ventilation and smoke exhaust cross-section, improve the smoke exhaust efficiency or increase the fresh air flow, and ensure the sealing after the adjustment is completed. An intelligent lifting system for partitions based on the tunnel horizontal guide ventilation and smoke exhaust mode. Utility Model Content

[0009] The utility model aims to provide a partition intelligent lifting system based on the tunnel flat ventilation and smoke exhaust mode, so as to solve the problem of the prior art that when a fire occurs in the tunnel and a large amount of smoke is generated, the flow rate of the smoke exhaust channel can be adjusted by adjusting the height of the partition.

[0010] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0012] Furthermore, a smoke exhaust passage is provided above the partition, and an air inlet passage is provided below the partition.

[0016] Furthermore, a jet fan is adapted to be provided above the partition.

[0017] The beneficial effects of the basic technical solution are:

[0018] (1) In order to facilitate the lifting and lowering of the partition and adjust the efficiency of the smoke exhaust channel by lifting and lowering the partition, lifting devices are evenly arranged on both sides of the horizontal guide. When in use, according to the smoke generated by the fire, the smoke sensor is received through the main control platform, so that the main control platform controls the operation of the hydraulic telescopic rod, so that the lifting of the hydraulic telescopic rod drives the T-shaped steel plate to lift, and the T-shaped steel plate drives the reinforcement plate on the surface to lift, so that the T-shaped steel plate and the reinforcement plate support the partition and drive the partition to lift, so that the lifting of the partition can adjust the size of the smoke exhaust channel and the air inlet channel.

When the lifting device completes the lifting of the partition, the main control platform controls the operation of the electric telescopic rod, so that the electric telescopic rod drives the sealing strip to extend and retract. The sealing strip is made of rubber material and has a certain elasticity. The electric telescopic rod pushes the sealing strip to contact the two sides of the inner wall of the flat guide, thereby sealing the intersection of the two sides of the partition and the flat guide to prevent smoke from diffusing to the flat guide.
