Description

Technical Field

[0001] This invention relates to the field of fire extinguishing system technology, and more particularly to a jet fire extinguishing system for tunnels. Background Technology

[0002] In the field of firefighting, tunnel fires are more dangerous and destructive than fires in other open spaces. This is because tunnels are long, narrow, and semi-enclosed spaces, preventing the rapid dissipation of heat and smoke generated by a fire. This leads to a rapid temperature increase and flashover, turning the entire tunnel section into an inferno. Simultaneously, the chimney effect of a fire acts like a fan, providing ample oxygen to the fire source, accelerating its spread, and causing hot, toxic smoke to fill the tunnel at an extremely rapid pace. Furthermore, the tunnel structure makes it difficult to coordinate personnel evacuation and the approach of external firefighters. Therefore, developing a new tunnel firefighting system that can improve the speed of fire detection within tunnels and effectively coordinate evacuation and firefighting operations after a fire is confirmed, thereby overcoming the aforementioned problems in existing technologies, is a direction that requires further research by those skilled in the art. Summary of the Invention

[0003] The purpose of this invention is to provide a jet fire extinguishing system for tunnels, which can improve the speed of fire detection in tunnels and achieve effective coordinated operation of evacuation and fire extinguishing after the fire is confirmed.

[0004] This invention provides a jet fire extinguishing system for tunnels, comprising:

[0005] An image detection component is distributed within the tunnel and is used to acquire images within the tunnel in real time and generate image signals.

[0006] The on-site fire-fighting components are distributed within the tunnel and are used to output fire-extinguishing liquid into the tunnel after entering the activation state.

[0007] An evacuation alarm component, which is used to perform an evacuation alarm task after entering the activation state;

[0008] A decision control component is provided, which is signal-connected to the image detection component, the on-site fire protection component, and the evacuation alarm component. The decision control component is used to read the image signal and determine a fire based on the image signal; and to control the evacuation alarm component to activate in real time when the fire determination result is true, and to control the evacuation alarm component to activate after a delay. The evacuation alarm component includes, but is not limited to, audible and visual alarms, broadcast alarms, lane indicators, and traffic lights.

[0009] By employing this technical solution: when a fire ignites within the tunnel, the image detection component on the fire monitor near the ignition point remotely monitors the area, generates image signals, and feeds them back to the decision control component. Based on the image signals, the decision control component determines that a fire has occurred and first activates the evacuation alarm component in real time to evacuate personnel from the tunnel. After a certain delay, it activates the on-site fire-fighting component with a delayed start. This ensures that the delayed activation of the on-site fire-fighting component does not affect the on-site personnel evacuation. Thus, effective coordinated operation of evacuation and firefighting is achieved after a fire is confirmed.

[0010] A preferred embodiment is that, in the aforementioned jet fire extinguishing system for tunnels, the on-site fire-fighting components include:

[0011] A fire monitor, which is configured to be rotatably mounted on the inner top wall of the tunnel boundary;

[0012] A ring-shaped liquid supply network is connected to the fire monitor and is used to pump extinguishing liquid to the fire monitor; the ring-shaped liquid supply network is fixedly installed on the inner wall of the tunnel.

[0013] The image detection component includes an image detector, which is fixedly installed on the fire monitor. The probe of the image detector moves synchronously with the muzzle of the fire monitor. The image detector is used to collect image signals within its probe coverage area in real time.

[0014] The decision control component is connected to the image detection component and the fire monitor signal respectively. The control system is used to receive the image signal and control the direction and operation of the fire monitor.

[0015] A preferred embodiment is that, in the aforementioned tunnel jet fire extinguishing system, the number of fire monitors is configured as several; these fire monitors are arranged at equal height and spacing along the tunnel's extension direction, on the same side boundary of the tunnel; the liquid supply pipeline is installed on the inner wall of the side of the tunnel where the fire monitors are installed. Specifically, the interval between two adjacent fire monitors is configured to be smaller than the detection coverage area of ​​a single detection system.

[0016] This technical solution employs a series of fire monitors distributed at equal intervals to achieve segmented monitoring and fire management within the tunnel. Furthermore, the decision control component can maintain the initial orientation of the fire monitors, ensuring that each image detection component, while stationary, covers the blind spots of its adjacent preceding component, thus guaranteeing the rapid detection of fire ignition points within the tunnel.

[0017] A preferred embodiment is that, in the aforementioned jet fire extinguishing system for tunnels, the detection system includes:

[0018] The number of field control cabinets is configured to match the number of fire monitors; and each field control cabinet is respectively connected to one of the fire monitors and the detection system signal connected to the fire monitor.

[0019] The control center is connected to each of the field control boxes via a fiber optic ring network.

[0020] This technical solution utilizes individual field control cabinets to locally operate the fire monitors connected to their respective signals, while the control center provides distributed control and signal exchange to these field control cabinets. In practice, regional control cabinets can be installed between the control center and the field control cabinets, allowing one regional control cabinet to simultaneously control several field control cabinets, and the control center to simultaneously control several others, thus achieving two-tiered distributed management. The control center is further configured to interact with external fire alarm systems and facilitate signal exchange.

[0021] A preferred embodiment is that, in the aforementioned tunnel jet fire extinguishing system, the fire monitor is configured to have a maximum horizontal rotation angle of 360° and a maximum vertical pitch angle of 120°.

[0022] In a preferred embodiment, the decision control component in the aforementioned tunnel jet fire extinguishing system further includes an external communication module, which is used to enable the decision module to access external fire alarm signals; the decision control component is also used to control the image detection component to start fire detection when the external fire alarm signal is accessed.

[0023] By adopting this technical solution, when an external fire alarm signal is received, the control image detection component actively searches for and locates the fire point, further improving the evacuation and firefighting response speed during a fire.

[0024] Preferably, in the above-mentioned jet fire extinguishing system for tunnels, the decision control component is configured to initiate fire detection based on the following steps:

[0025] The decision control component is configured to initiate fire detection based on the following steps:

[0026] Step 110: After receiving an external fire alarm signal, control the image detection component to start at the initial position and perform a 10-second detection. If the image detection component detects a flame, the image detection component will remain at the current position and locate the fire point; otherwise, proceed to step 111.

[0027] Step 111: The image detection component rotates from its initial horizontal position to a preset first horizontal field of view in the horizontal direction and keeps its position unchanged in the vertical direction for 10 seconds; if the image detection component detects a flame, the image detection component remains in its current position and locates the ignition point; otherwise, proceed to step 112.

[0028] Step 112: The image detection component rotates from its initial vertical position to a preset near-field vertical position in the vertical direction, and keeps its position unchanged in the horizontal direction for 10 seconds. If the image detection component detects a flame, it stays in its current position and locates the ignition point; otherwise, proceed to step 113.

[0029] Step 113: The image detection component rotates to its initial horizontal position and remains unchanged in the vertical direction for 10 seconds. If the image detection component detects a flame, it remains in its current position and locates the ignition point; otherwise, proceed to step 114.

[0030] Step 114: The image detection component rotates vertically from the near vertical field of view to the initial vertical position, while maintaining its position in the horizontal direction. At this time, the image detection component device moves to the initial position.

[0031] By adopting the above technical solution, when an external fire alarm signal is received, the automatic stand-alone mode is used to automatically locate the fire point using the image detection component on the adjacent fire monitor closest to the fire point. After the location is completed, the fire monitor with the image detection component is used to automatically locate and extinguish the fire.

[0032] Another preferred embodiment is that, in the aforementioned jet fire extinguishing system for tunnels, the decision control component is configured to initiate fire detection based on the following steps:

[0033] Step 210: After receiving an external alarm signal, control the first image detection component to start detection for 10 seconds at its initial position. If the first image detection component detects a flame, control the first image detection component to remain at its current position and locate the ignition point, and then proceed to step 220.

[0034] Step 220: Control the second image detection component adjacent to the first image detection component to start, rotate it from its initial horizontal position to a preset second horizontal position in the horizontal direction, and keep its position unchanged in the vertical direction; when the field of view of the second image detection component in the horizontal direction partially overlaps with the field of view of the first image detection component at its initial position and completely covers the current field of view of the first image detection component; instruct the second image detection component to perform detection for 10 seconds. If the second image detection component detects a flame, the second image detection component remains in its current position and performs fire point location; otherwise, proceed to step 230.

[0035] Step 230: Control the second image detection component to rotate vertically to a preset near-field vertical view position, while keeping the horizontal position unchanged; instruct the second image detection component to perform a 10-second detection. If the second image detection component detects a flame, it remains in its current position and locates the ignition point; otherwise, proceed to step 240.

[0036] Step 240: Control the second image detection component 300 to rotate vertically to a preset remote vertical field of view position and horizontally to a third horizontal position, so that the second image detection component 300 can perform a 10-second detection. If the second image detection component 300 detects a flame, the second image detection component 300 will remain in the current position and locate the ignition point; otherwise, proceed to step 250.

[0037] Step 250: Control the second image detection component 300 to remain stationary in the horizontal direction and rotate it to a near vertical field of view position in the vertical direction, so that the second image detection component 300 can perform detection for 10 seconds. Once the second image detection component 300 detects a flame, the second image detection component 300 will remain in the current position and locate the ignition point.

[0038] By adopting the above technical solution, when an external fire alarm signal is received, the automatic online mode is used to automatically locate the fire point using image detection components installed on two adjacent fire monitors near the fire point. After the location is completed, the two adjacent fire monitors can work together to extinguish the fire.

[0039] Compared with the prior art, the present invention has achieved the following technical advancements:

[0040] First, this equipment can implement the working logic of "alarm priority and delayed spraying", putting personnel safety first and avoiding the obstruction of evacuation work caused by fire extinguishing operations.

[0055] The image detection component 300 includes an image detector, the number of which is the same as the number of fire monitors 100. Each fire monitor 100 is equipped with one image detector, and the probe of the image detector moves synchronously with the movement of the nozzle of the fire monitor 100. The image detector is used to collect image signals within its probe coverage area in real time.

[0056] The decision control component is connected to the image detection component 300 and the fire monitor 100 respectively. The control system is used to receive the image signals and control the turning and operation of the fire monitor 100.
