Description

Technical Field

[0001] This application belongs to the technical field of tunnel disaster prevention and mitigation, and specifically relates to a gas-water curtain smoke isolation wind speed regulation system and its control method in a tunnel. Background Art

[0002] Tunnels are important structures for transportation and infrastructure construction. However, tunnel fires pose a serious safety threat, causing not only property damage but also potential casualties and traffic disruptions. In tunnel fires, smoke is one of the main factors leading to casualties and safety risks. Therefore, effective control and isolation of smoke are crucial in tunnel fire emergency response. Traditional tunnel fire control methods mainly rely on fire extinguishing systems and ventilation systems. However, these methods have some problems and limitations. For example, the ventilation system may accelerate the spread of smoke during a fire, and the fire extinguishing system may not respond immediately or may not be effective in extinguishing fires in some cases.

[0003] Currently, common smoke control methods also include mechanical smoke exhaust and gas / liquid barriers, etc. Among them, gas / liquid barriers mainly use gas curtains or water curtains to form an "air / liquid wall" to block and control the flow of smoke. However, existing gas-water curtain systems are relatively single and fixed in terms of spraying angle and speed, and cannot make timely adjustments according to different wind speed and direction conditions. When there is a large wind speed in the tunnel, the gas-water curtain sprayed at a fixed angle is easily broken by the wind, losing the shielding effect and making it difficult to fully play the role of the gas-water curtain in isolating smoke. Summary of the Invention

[0004] Aiming at the above defects or requirements for improvement in the prior art solutions, the present invention provides a gas-water curtain smoke isolation wind speed regulation system and its control method in a tunnel, which can start the gas-water curtain in a timely manner during a fire, dynamically adjust its operating parameters according to the ambient wind speed, effectively isolate the smoke, and prevent it from entering other smoke control zones, thereby reducing the harm and losses caused by the fire.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A gas-water curtain smoke isolation wind speed regulation system in a tunnel includes a tunnel, multiple smoke control zones, a tunnel fire extinguishing device, a gas curtain generating device, a water curtain generating device, a fire detection alarm, and a controller. Gas curtain generating devices and water curtain generating devices are arranged at the junctions of the smoke control zones. The gas curtain generating device is used to form a gas curtain, and the water curtain generating device is used to form a water curtain. The spraying angles and speeds of the gas curtain and the water curtain are adjustable. The fire detection alarm is used to detect the occurrence of a fire in the smoke control zones in the tunnel; A plurality of wind speed sensors are evenly arranged on the top plates of each smoke control zone. The controller is electrically connected to the gas curtain generating device, the water curtain generating device, and the wind speed sensors, and adjusts the spraying angles and speeds of the gas curtain and the water curtain based on the wind speed information collected by the wind speed sensors.

[0006] Preferably, two water curtain generating devices and one air curtain generating device are alternately arranged at the junction of the tobacco control zones, wherein the two water curtain generating devices are arranged on the outside, and one air curtain generating device is in the middle of the two water curtain generating devices, forming a water curtain - air curtain - water curtain structure.

[0007] Preferably, the air curtain generating device is provided with a plurality of air curtain electrically controlled nozzles, and the water curtain generating device is provided with a plurality of water curtain electrically controlled nozzles.

[0008] Preferably, the adjustment range of the spraying angle is within 30° deviating from the vertical direction.

[0009] Preferably, the controller pre - stores a wind speed threshold value, a preset spraying angle and speed, and selects the preset spraying angle and speed based on the wind speed threshold value.

[0010] The present invention also discloses a control method based on the above - mentioned air - water curtain smoke isolation wind speed regulation system in the tunnel, which is characterized by including the following steps:

[0011] S1: When the fire detection alarm detects a fire in a certain tobacco control zone in the tunnel, the air curtain generating device and the water curtain generating device are started to form an air curtain and a water curtain, and the air curtain and the water curtain are sprayed in the vertical direction;

[0012] S2: The controller obtains a plurality of wind speed values collected by a plurality of wind speed sensors in the tobacco control zone adjacent to the tobacco control zone where the fire occurs, and obtains the average wind speed V;

[0013] S3: When the average wind speed V of the adjacent tobacco control zone is greater than the first wind speed threshold value V1, the air curtain and the water curtain at the junction of the tobacco control zone where the fire occurs and the adjacent tobacco control zone are inclined to the outside of the tobacco control zone where the fire occurs by a first spraying angle. When the average wind speed V is greater than the second wind speed threshold value V2, the air curtain and the water curtain are inclined to the outside of the tobacco control zone where the fire occurs by a second spraying angle, and the second wind speed threshold value V2 is greater than the first wind speed threshold value V1;

[0014] S4: When the average wind speed V of the adjacent tobacco control zone is less than the third wind speed threshold value V3, the air curtain and the water curtain resume spraying in the vertical direction, and the third wind speed threshold value V3 is less than the first wind speed threshold value V1.

[0015] Preferably, in step S3, when the air curtain and the water curtain are inclined to the outside of the tobacco control zone where the fire occurs by the first angle, the spraying speed is increased to 1.5 times the initial spraying speed. When the air curtain and the water curtain are inclined to the outside of the tobacco control zone where the fire occurs by the second angle, the spraying speed is increased to 2 times the initial spraying speed.

[0016] Preferably, in step S4, when the air curtain and the water curtain resume spraying in the vertical direction, the spraying speed resumes to the initial spraying speed.

[0017] Preferably, when the average wind speed V of the adjacent smoke control zone is detected to be greater than the fourth wind speed threshold V4, where the fourth wind speed threshold V4 is greater than the second wind speed threshold V2, the air curtain and water curtain of the adjacent smoke control zone on the other side of the smoke control zone where the fire occurs are controlled to open.

[0018] Preferably, the controller monitors the states of the air curtain and water curtain in real time and transmits information to the remote monitoring center through the network.

[0019] The beneficial effects of the present invention are as follows: The present invention adopts an air-water curtain smoke isolation wind speed adjustment system, which can be quickly started during a fire to form an air-water curtain, effectively isolating the smoke, thereby improving the efficiency of tunnel fire emergency treatment. Compared with the traditional ventilation system and fire extinguishing system, this system can respond and control the smoke spread more quickly, reducing the losses caused by the fire. The present invention adopts a design that can adjust the spraying angle according to the wind speed. When the wind speed is large, the air-water curtain will automatically tilt at a certain angle to form an air-water curtain that is more conducive to resisting the wind force, avoiding being directly broken by the wind force. At the same time, the spraying speed also increases with the increase of the wind speed, further enhancing the stability and blocking ability of the air-water curtain. In addition, the system will also start the air-water curtain in the adjacent area to form a linkage prevention and control, effectively preventing the large-scale diffusion of smoke.

Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the present invention.

[0026] In addition, the described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be employed. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present application.

[0027] Please refer to Figures 1 - 3 , this embodiment provides a system for adjusting the wind speed of gas-water curtain smoke isolation in a tunnel, including a tunnel 1, multiple smoke control zones 2, a tunnel fire extinguishing device 3, a gas curtain generating device 4, a water curtain generating device 5, a fire detection alarm 6, and a controller. At the junction of two adjacent smoke control zones 2, a gas curtain generating device 4 and a water curtain generating device 5 are provided. The gas curtain generating device 4 is used to form a gas curtain 41, and the water curtain generating device 5 is used to form a water curtain 51. The gas curtain 41 and the water curtain 51 can adjust the spraying angle and spraying speed as needed to adapt to different wind speed and wind direction conditions. A fire detection alarm 6 is also arranged in each smoke control zone 2 to detect a fire in a timely manner and send an alarm signal. Considering that the wind speed and wind direction in the tunnel are important factors affecting smoke control, a plurality of wind speed sensors 7 are evenly arranged on the top plate of each smoke control zone 2 to collect the wind speed data in the tunnel in real time.

[0028] The controller is the control core of the entire system, and it is electrically connected to the gas curtain generating device 4, the water curtain generating device 5, and the wind speed sensors 7. The controller receives the data fed back by the wind speed sensors 7 in real time and adjusts the spraying angle and speed of the gas curtain 41 and the water curtain 51 based on the wind speed information collected by the wind speed sensors 7.

[0029] When a fire occurs in a certain smoke control zone 2, the gas curtain generating device 4 and the water curtain generating device 5 at the boundary of this area are activated to form a gas curtain 41 and a water curtain 51 on both sides, blocking the outflow of smoke. At the same time, the wind speed sensors 7 in the adjacent areas collect the wind speed data and transmit it to the controller. The controller adjusts the spraying angle of the gas curtain 41 and the water curtain 51 according to the wind speed, making it tilt at a certain angle on the windward side to increase the windward area with the incoming flow wind. In addition, the spraying speed is also correspondingly increased to further enhance the ability of the gas-water curtain to resist the wind. Through the optimized adjustment of the spraying angle and speed, a dynamic barrier with enhanced wind resistance is formed, effectively blocking the promoting effect of the wind speed on the spread of smoke and minimizing the smoke control in the fire occurrence area.

[0030] Further, at the junction of two adjacent smoke control zones 2, two water curtain generating devices 5 and one air curtain generating device 4 are alternately arranged. Specifically, the two water curtain generating devices 5 are arranged on the outside, and one air curtain generating device 4 is in the middle of the two water curtain generating devices. In this way, a sandwich-style smoke separation structure of "water curtain 51 - air curtain 41 - water curtain 51" will be formed when starting. By adopting the alternately arranged scheme, the respective advantages of the air curtain and the water curtain are further exerted, making the two complement each other, constructing a reliable smoke prevention barrier, so as to maximize the blocking and control of smoke, and having more excellent comprehensive smoke prevention performance than a single air curtain or water curtain scheme, and can meet the high safety requirements of places such as tunnels.

[0031] Specifically, in this embodiment, the air curtain generating device 4 is provided with a plurality of air curtain electrically controlled nozzles, and the water curtain generating device 5 is provided with a plurality of water curtain electrically controlled nozzles. These electrically controlled nozzles are respectively electrically connected to the controller and can independently adjust the spraying angle and spraying speed according to the instructions issued by the controller. By using a plurality of independently controllable electrically controlled nozzles, fine control of the air curtain 41 and the water curtain 51 can be realized, and the spraying parameters can be optimized and adjusted locally according to the actual situation.

[0032] Further, this embodiment preferably selects the adjustment range of the spraying angle and limits it within 30° from the vertical direction. Within 30° deviation, the air curtain 41 and the water curtain 51 can still maintain a good smoke separation effect. An excessive deviation angle will reduce the effective shielding height of the air curtain 41 and the water curtain 51, which is not conducive to blocking smoke. An appropriate angle adjustment range can meet the adaptability to the wind speed while avoiding the overly complex structure of the nozzle. Of course, this angle range is not the only limitation and can be adjusted appropriately according to actual needs.

[0033] In terms of the control strategy, a plurality of wind speed thresholds and a series of corresponding preset spraying angles and spraying speeds are pre-stored in the controller of this embodiment. When the wind speed data detected by the actual wind speed sensor 7 reaches a certain threshold, the controller can directly call the corresponding preset spraying parameters, respond quickly, and timely adjust the states of the air curtain 41 and the water curtain 51, without repeated calculation, improving the reaction speed of the system. At the same time, this hierarchical control method based on wind speed thresholds can avoid frequent small adjustments, reduce the wear of the nozzle mechanism, and extend the service life.

[0034] Please refer to Figure 4 , another embodiment of the present invention proposes a control method based on the above-mentioned air-water curtain smoke isolation wind speed adjustment system in the tunnel, including the following steps:

[0035] S1: When the fire detection alarm 6 detects a fire in a certain smoke control zone 2 in the tunnel 1, the air curtain generating device 4 and the water curtain generating device 5 are started to form an air curtain 41 and a water curtain 51, and the air curtain 41 and the water curtain 51 are initially sprayed in the vertical direction.

[0036] The purpose of this step is to quickly activate the air curtain 41 and the water curtain 51 at the first moment of a fire, and form a smoke isolation barrier at the junction of adjacent smoke control zones 2. Vertical spraying is the default state of the air curtain 41 and the water curtain 51, which can meet the basic smoke isolation requirements under windless or light wind conditions.

[0037] S2: The controller obtains multiple wind speed values collected by multiple wind speed sensors 7 in the smoke control zones adjacent to the smoke control zone 2 where the fire occurs, and calculates the average wind speed V.

[0038] The purpose of this step is to obtain the real-time wind speed data of the adjacent area through the wind speed sensor 7, and calculate the overall wind speed level of this area through the average value. This average wind speed V is an important basis for adjusting the spraying angles of the air curtain 41 and the water curtain 51 subsequently. Since the wind speed condition of the adjacent area has a direct impact on the smoke flow in the fire area, it is more reasonable and reliable to select the wind speed data of the adjacent area as the judgment basis.

[0039] S3: When the average wind speed V of the adjacent smoke control zone is greater than the first wind speed threshold V1, the air curtain 41 and the water curtain 51 at the junction of the smoke control zone 2 where the fire occurs and the adjacent smoke control zone tilt outward to the smoke control zone 2 where the fire occurs by the first spraying angle; when the average wind speed V is greater than the second wind speed threshold V2, the air curtain 41 and the water curtain 51 tilt outward to the smoke control zone 2 where the fire occurs by the second spraying angle, and the second wind speed threshold V2 is greater than the first wind speed threshold V1.

[0040] The purpose of this step is to adjust the spraying angles of the air curtain 41 and the water curtain 51 according to different wind speed levels, so that they can adapt to the wind speed change and better block and control the smoke. When the wind speed exceeds the first threshold V1, it indicates that the wind speed begins to have a certain impact on the smoke flow, and it is necessary to enhance the wind resistance by tilting the air and water curtains. As the wind speed further increases, the tilting angle also increases accordingly to provide a stronger blocking effect. The first spraying angle is less than the second spraying angle, corresponding to a smaller wind speed threshold, realizing a multi-level response, which is more refined and intelligent.

[0041] S4: When the average wind speed V of the adjacent smoke control zone is less than the third wind speed threshold V3, the air curtain 41 and the water curtain 51 resume vertical spraying, and the third wind speed threshold V3 is less than the first wind speed threshold V1.

[0042] The purpose of this step is to promptly resume the vertical spraying state of the air curtain 41 and the water curtain 51 when the wind speed drops to a certain extent and no longer has an obvious impact on the smoke flow. This can reduce unnecessary energy consumption while ensuring the basic smoke isolation effect. The setting of the third wind speed threshold V3 needs to comprehensively consider the smoke isolation performance and energy-saving factors, and is optimized through experiments and simulations.

[0043] The control method proposed in this embodiment makes full use of the data real-time monitored by the wind speed sensor 7. By setting different wind speed thresholds and corresponding tilt angles, it realizes the dynamic matching of the spraying states of the air curtain 41 and the water curtain 51 with the wind speed, greatly improving the adaptability of the system to wind speed changes. At the same time, by adopting a hierarchical response and an automatic recovery mechanism, it takes into account both the smoke separation effect and energy consumption optimization, and has a very high level of intelligence and practical value.

[0044] Furthermore, in step S3, when the air curtain 41 and the water curtain 51 tilt towards the outside of the smoke control zone 2 where the fire occurs by the first angle, the spraying speed increases to 1.5 times the initial spraying speed; when the air curtain 41 and the water curtain 51 tilt towards the outside of the smoke control zone 2 where the fire occurs by the second angle, the spraying speed increases to 2 times the initial spraying speed. While increasing the spraying angle, coordinating with increasing the spraying speed can further enhance the wind resistance ability of the air curtain 41 and the water curtain 51. A higher speed can make the gas and water column penetrate the wind field more effectively, forming a more stable smoke separation barrier. At the same time, as the angle increases, the spraying speed also increases accordingly, showing a synergistic effect and better adapting to different wind speed levels. The speed increase amplitudes of 1.5 times and 2 times are preferably obtained based on experience and experimental data, which can not only meet the performance requirements but also avoid excessive energy consumption waste.

[0045] In addition, in step S4, when the air curtain 41 and the water curtain 51 resume spraying in the vertical direction, the spraying speed also resumes to the initial spraying speed. When the wind speed drops below the third threshold and the influence of wind force on the smoke flow is small, not only the angles of the air curtain 41 and the water curtain 51 need to be restored to the vertical state, but also the spraying speed needs to be restored to the initial value. On the one hand, this can be consistent with the angle adjustment to avoid excessive spraying; on the other hand, reducing the spraying speed can save energy and water resources and reduce unnecessary consumption.

[0046] Furthermore, when it is detected that the average wind speed V of the adjacent smoke control zone is greater than the fourth wind speed threshold V4, the air curtain 41 and the water curtain 51 of the adjacent smoke control zone on the other side of the smoke control zone 2 where the fire occurs are controlled to be turned on, and the fourth wind speed threshold V4 is greater than the second wind speed threshold V2. In the case of a relatively high wind speed in the tunnel, the strong wind will exacerbate the spread of the smoke in the fire area downstream. It may be difficult for only the air and water curtains on the upstream side of the fire area to completely block the spread of the smoke. In order to fundamentally control the spread of the smoke in the tunnel, it is necessary to also turn on the air curtain 41 and the water curtain 51 in the adjacent smoke control zone in the downstream direction, which becomes the second line of defense, forming a linkage prevention and control to effectively prevent the large-scale spread of the smoke.

[0047] In some embodiments, the controller monitors the states of the air curtain 41 and the water curtain 51 in real time and transmits information to the remote monitoring center via the network. Real-time monitoring of the operating states of the air curtain 41 and the water curtain 51, including the spraying angles, speeds, and fault conditions, etc., can detect and handle problems in a timely manner to ensure the normal operation of the system. This remote monitoring mechanism improves the safety and maintainability of the system and is an important manifestation of modern intelligent management.

[0048] In summary, the present invention provides a system for regulating the smoke isolation wind speed of an air-water curtain in a tunnel and its control method. By setting multiple smoke control zones in the tunnel and arranging air curtain generating devices and water curtain generating devices with adjustable angles and speeds at the junctions of adjacent zones, and simultaneously using distributed wind speed sensors to monitor the wind speed conditions in the tunnel in real time, and dynamically adjusting the spraying parameters of the air curtain and the water curtain according to the wind speed, an adaptive matching between the smoke barrier ability and the wind speed in the tunnel is achieved. This system has important practical significance and popularization value for enhancing the smoke control ability in tunnel fire accidents and ensuring the safety of personnel and property. With the continuous maturity and improvement of technology, this innovative intelligent smoke prevention system will surely be widely applied in the field of tunnel engineering, providing a strong guarantee for the safe, efficient, and green operation and management of tunnels.
