Description

Technical Field

[0001] This utility model relates to the technical field of bridge fire extinguishing, specifically to an integrated bridge fire extinguishing system. Background Technology

[0002] Bridges, as key hubs in modern transportation networks, are of paramount importance for safe operation. However, bridge structures, especially long-span cable-stayed bridges, face severe fire risks. Incidents such as vehicle fires on bridges and fuel leaks from traffic accidents are common. Once a fire occurs, it not only causes traffic disruptions and significant economic losses, but can also cause irreversible damage to the main bridge structure (such as steel box girders and cables), leading to catastrophic consequences.

[0003] Currently, fire protection measures for bridges are relatively limited and have significant shortcomings. Common methods mainly rely on the following two: First, rely on external rescue. This means waiting for fire trucks to arrive at the scene from under the bridge or at both ends of the bridge. However, bridges are usually located on major traffic arteries, especially during peak traffic hours, making it difficult for fire trucks to arrive quickly. At the same time, the height and special structure of bridges make it difficult for the elevated spray devices on fire trucks to effectively cover all fire points, especially for fires below the bridge deck or in the cable-stayed areas, often leaving them helpless and easily missing the best opportunity to extinguish the fire.

[0004] Secondly, simple fire-fighting facilities are provided. Some bridges are equipped with portable fire extinguishers or fixed fire hydrants. However, portable fire extinguishers have a small capacity, which is insufficient for larger fires such as vehicle fuel fires, and they require close-range operation, posing a high risk. For example, CN218552941U discloses a fire extinguishing device for steel main beam bridges, which has a housing for the fire extinguisher, requiring the user to hold the extinguisher to put out the fire.

[0005] Some fire suppression systems can only spray water, which is ineffective against oil and electrical fires; while some systems can release foam or dry powder, they mostly provide localized protection and lack the ability to monitor and coordinate the entire bridge deck and critical structures. When a fire occurs, they cannot intelligently select the most effective extinguishing medium (water, foam, or dry powder) and spraying device (high-flow jet device or covering spray device) for precise targeting based on the type, location, and scale of the fire source.

[0006] Therefore, there is an urgent need in this field for a highly efficient integrated bridge fire extinguishing system that can overcome the above-mentioned defects, achieve all-weather automatic monitoring, rapid response, and intelligently select multiple fire extinguishing methods according to the fire situation. Utility Model Content

[0007] This utility model proposes an integrated bridge fire extinguishing system, which realizes 24-hour automatic monitoring of bridges. The system integrates a water source and a fire extinguishing agent storage tank, and can intelligently select to spray water or release foam / dry powder according to the fire situation, thus solving the defects of existing facilities with single functions.

[0008] An integrated bridge fire extinguishing system designed for this purpose includes a controller, a water supply mechanism and / or a storage tank, a monitoring mechanism installed on the bridge, an automatic jet fire extinguishing device and / or a spraying device; The monitoring mechanism is used to detect the bridge status in real time and is electrically connected to the controller. The water inlet of the automatic jet fire extinguishing device is connected to the water outlet of the water supply mechanism. The electrical control part of the water supply mechanism is electrically connected to the controller. The controller drives the water supply mechanism to deliver liquid for fire extinguishing to the automatic jet fire extinguishing device according to the monitoring status of the monitoring mechanism. The storage tank is used to store fire extinguishing foam or dry powder, and the input end of the spraying device is connected to the outlet end of the storage tank so that the storage tank can deliver foam or dry powder to the spraying device.

[0009] It also includes a back-end terminal, which is connected to the spraying device remotely to remotely start the spraying device; Alternatively, the spraying device may have a manual button for manually activating the spraying device. Alternatively, the spraying device can be electrically connected to the monitoring agency, which can trigger the spraying device to start based on the bridge monitoring status.

[0010] The water supply mechanism includes a delivery pipeline and a water pump. The water pump input end is connected to a water source, and the water pump output end is connected to the delivery pipeline. The water source is delivered to the automatic jet fire extinguishing device via the water pump and the delivery pipeline. The water pump is electrically connected to the controller.

[0011] The bridge is equipped with a first column for supporting the installation of an automatic jet fire extinguishing device. The automatic jet fire extinguishing device includes a housing, a spray pipe, an infrared locator, and a camera.

[0012] The automatic jet fire extinguishing device and the spraying device are provided in several units, and the automatic jet fire extinguishing device and the spraying device are respectively arranged at intervals along the length of the bridge on the side of the bridge.

[0013] The monitoring mechanism includes temperature sensors and / or infrared imagers and / or cameras, heat source monitoring equipment and / or dual-wavelength / multi-band flame detectors and / or temperature-sensing optical fibers.

[0014] The temperature sensor and the infrared imager are respectively installed on the bridge deck, and a second column is provided on the bridge to support the camera and heat source monitoring equipment.

[0015] The bridge is equipped with a third column for supporting the installation of the spraying device.

[0016] The integrated bridge fire extinguishing system also includes an alarm module, which is electrically connected to the controller. The alarm module includes an audible alarm and / or a light alarm.

[0017] A supply pipe is provided between the storage tank and the input end of the spraying device. A power mechanism is connected to the outside of the storage tank to transport the foam or dry powder in the storage tank to the spraying device. The power mechanism is electrically connected to the controller.

[0018] The bridge is equipped with a fire-fighting robot that replaces the automatic jet fire extinguishing device and spraying device. The bridge has a slide rail on the guardrail. The bottom of the fire-fighting robot has a slide plate that slides on the slide rail. A drive mechanism for moving the fire-fighting robot is provided between the slide plate and the slide rail. The automatic jet fire extinguishing device, spraying device and fire extinguishing robot constitute the fire extinguishing equipment. The fire extinguishing equipment is remotely or wiredly connected to a monitoring platform via WiFi. The fire extinguishing equipment is also remotely or wiredly connected to a monitoring agency on the bridge via WiFi.

[0019] It also includes an emergency communication module and a processing module for identifying vehicle types from the collected images. The identified types include: cars, light trucks, medium trucks, large trucks, special vehicles, and engineering vehicles. Based on the identification results from the processing module, the controller determines the vehicle type and fire situation, selects and activates the corresponding fire extinguishing equipment, and executes the appropriate fire extinguishing strategy. The emergency communication module includes a wireless intercom device installed on the side of the bridge, which can establish voice communication with the driver when the vehicle is identified as a special vehicle or a vehicle transporting flammable materials or dangerous goods.

[0020] A control method for an integrated bridge fire extinguishing system as described above, wherein the integrated bridge fire extinguishing system further includes an image processing module with built-in corresponding image data; the image processing module is communicatively connected to the monitoring agency 2 and is used to identify vehicle type from the acquired images; Its control method includes the following steps: S1: Real-time collection of images, temperature, and flame signal data from the bridge via monitoring agencies; S2: The processing module analyzes the collected data to identify the location of the fire and the type of vehicle involved; S3: Determine whether the vehicle type is a special vehicle or other dangerous goods transport vehicle; S4: Select and activate the appropriate fire extinguishing equipment based on the vehicle type and the fire situation.

[0021] The vehicle type identification in step S2 includes: classifying vehicles into cars, small trucks, medium trucks, large trucks, special vehicles, or engineering vehicles by comparing their appearance and size characteristics through image recognition; if it is a special vehicle carrying hazardous materials, after issuing a warning signal to the control center, the system is connected to the network in real time, and a wireless intercom system and a communication medium for the driver are set up on the side of the bridge. If the driver cannot connect, the system is activated through on-site video to communicate the appropriate fire extinguishing agent for fire extinguishing operations.

[0022] The beneficial technical effects of this utility model are as follows: By integrating monitoring mechanisms, automatic jet fire extinguishing devices, and spraying devices, and linking them with a controller, the system achieves 24-hour unmanned automatic monitoring and rapid response to bridge fires, overcoming the delays caused by relying on external rescue. At the same time, the system integrates water sources and fire extinguishing agent storage tanks, and can intelligently select to spray water or release foam / dry powder according to the fire situation, solving the shortcomings of existing facilities in terms of single function and insufficient ability to deal with complex fires, and achieving precise and efficient fire extinguishing.

[0023] The independent water supply system, consisting of pumps and pipelines, can quickly draw water directly from the water source under the bridge or the municipal pipe network, providing a stable and sufficient water source for the automatic jet fire extinguishing device. This ensures the continuity of fire extinguishing and meets the demand for large flow rates, overcoming the bottleneck of limited water storage capacity in traditional fire trucks.

[0024] The automatic jet fire extinguishing device is erected on the first column and combined with an infrared locator and a camera, giving the automatic jet fire extinguishing device the function of "eyes". This allows it to automatically scan and accurately locate the fire source and drive the spray pipe to aim, achieving precise strikes on the bridge surface or specific areas and greatly reducing the waste of fire extinguishing agent.

[0025] By arranging various fire extinguishing devices at intervals along the length of the bridge, a fire extinguishing network covering the entire bridge protection zone is formed, eliminating blind spots in monitoring and firefighting. No matter where a fire occurs on the bridge deck, the nearest device can be quickly activated to achieve early suppression and prevent the fire from spreading. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0039] See Figures 1-12 An integrated bridge fire extinguishing system includes a controller 1, a water supply mechanism 6 and / or a storage tank 7, a monitoring mechanism 2 installed on the bridge 5, an automatic jet fire extinguishing device 3 and / or a spraying device 4. The monitoring mechanism 2 is used to detect the status of the bridge 5 in real time and is electrically connected to the controller 1. The water inlet of the automatic jet fire extinguishing device 3 is connected to the water outlet of the water supply mechanism 6. The electrical control part of the water supply mechanism 6 is electrically connected to the controller 1. The controller 1 drives the water supply mechanism 6 to deliver liquid for fire extinguishing to the automatic jet fire extinguishing device 3 according to the monitoring status of the monitoring mechanism 2. The storage tank 7 is used to store fire extinguishing foam or dry powder, and the input end of the spraying device 4 is connected to the outlet end of the storage tank 7 so that the storage tank 7 can deliver foam or dry powder to the spraying device 4.

[0040] The monitoring unit 2 monitors the status of bridge 5 in real time and feeds it back to controller 1, achieving uninterrupted fire monitoring around the clock. Controller 1, based on the monitoring results, activates the water supply unit 6 or the storage tank 7. The automatic jet extinguishing device 3 can obtain extinguishing liquid through the water supply unit 6, enabling rapid response to ordinary fires. The spraying device 4 can receive foam or dry powder from the storage tank 7, and can handle special fires such as oil and electrical fires, overcoming the shortcomings of traditional systems that rely on a single extinguishing medium. The system integrates monitoring, control, and extinguishing functions, with a response speed far exceeding traditional methods, and eliminates the need for close-range personnel operation, reducing operational risks.

[0041] The integrated bridge fire extinguishing system also includes a back-end terminal 8, which is connected to the spraying device 4 via a remote network to remotely activate the spraying device 4. Alternatively, the spraying device 4 may be equipped with a manual button 9 for manually activating the spraying device 4. Alternatively, the spraying device 4 is electrically connected to the monitoring agency 2, and the monitoring agency 2 triggers the spraying device 4 to start based on the monitoring status of the bridge 5.

[0042] The back-end terminal 8 remotely activates the sprinkler system 4 via network connection, enabling fire suppression without on-site arrival. This is suitable for scenarios with high fire risk or where personnel cannot approach, enhancing emergency response flexibility. A manual button 9 serves as a backup activation method, allowing the sprinkler system 4 to still activate even if automatic or remote control fails, preventing delays in fire suppression due to a single activation method malfunction and ensuring system reliability. The sprinkler system 4 is electrically connected to the monitoring unit 2, allowing it to be directly triggered by fire monitoring results, maintaining the automation and continuity of fire suppression actions. These three activation methods complement each other, forming multiple safeguards to ensure timely activation of the sprinkler system 4 for fire suppression in various scenarios.

[0043] The water supply mechanism 6 includes a delivery pipe 601 and a water pump 602. The input end of the water pump 602 is connected to a water source, and the output end of the water pump 602 is connected to the delivery pipe 601. The water source is delivered to the automatic jet fire extinguishing device 3 via the water pump 602 and the delivery pipe 601. The water pump 602 is electrically connected to the controller 1.

[0044] The water pump 602 provides stable power to the water supply mechanism 6, ensuring that water can be quickly delivered to the automatic jet fire extinguishing device 3. The water source can be municipal water or river water, etc.

[0045] The bridge 5 is provided with a first column for supporting the installation of the automatic jet fire extinguishing device 3. The automatic jet fire extinguishing device 3 includes a housing 301, a spray pipe 302, an infrared locator, and a camera 303.

[0046] The first column provides a stable installation support for the automatic jet fire extinguishing device 3. The infrared locator and camera 303 of the automatic jet fire extinguishing device 3 can accurately identify the location of the fire source and guide the spray pipe 302 to spray the fire extinguishing liquid in a directional manner, so as to extinguish the fire according to the source of the disaster.

[0047] The automatic jet fire extinguishing device 3 and the spraying device 4 are provided in several units. The automatic jet fire extinguishing device 3 and the spraying device 4 are respectively arranged at intervals along the length of the bridge 5 on the side of the bridge 5.

[0048] Several automatic jet fire extinguishing devices 3 and spraying devices 4 are spaced apart along the length of bridge 5, achieving full coverage of the entire length of bridge 5. This eliminates the fire extinguishing blind spots present in traditional local protection methods, and is particularly suitable for the long-distance protection needs of large-span bridges. When multiple devices work together, they can be activated simultaneously to deal with large-scale fires, quickly suppressing the spread of fire and preventing irreversible damage to the main structure of bridge 5 from the fire escalating.

[0049] The monitoring device 2 includes a temperature sensor and / or an infrared imager and / or a camera, a heat source monitoring device and / or a dual-wavelength / multi-band flame detector and / or a temperature-sensing fiber optic cable.

[0050] Temperature sensors can capture bridge surface temperature anomalies in real time, infrared imagers can visually present the distribution of fire sources, camera heat source monitoring equipment can visually track changes in the fire situation, dual-wavelength / multi-band flame detectors can accurately identify flame signals, and temperature-sensing fiber optics are adapted for long-distance bridge surface temperature monitoring. Multiple devices form a complementary monitoring system.

[0051] Using multiple sensors simultaneously solves the problem of false alarms and missed alarms caused by single monitoring devices. By cross-validating multi-dimensional monitoring data, the accuracy and reliability of fire identification are improved, ensuring early detection of fires and accurate assessment of fire status, and providing comprehensive data support for controller 1 to formulate fire extinguishing strategies.

[0052] The temperature sensor and the infrared imager are respectively installed on the bridge surface of bridge 5, and a second column is provided on bridge 5 for installing and supporting the camera heat source monitoring equipment.

[0053] The bridge 5 is equipped with a third column for supporting the installation of the spraying device 4.

[0054] Temperature sensors and infrared imagers are mounted on the bridge deck of Bridge 5, allowing for close-range monitoring of the area and enhancing the sensitivity of detecting temperature anomalies and fires, enabling early and rapid fire detection. The second column provides a suitable installation height for the camera-based heat source monitoring equipment, expanding the monitoring field of view and ensuring coverage of a larger area of ​​the bridge deck, minimizing blind spots. The third column provides stable support for the spraying device 4.

[0055] The integrated bridge fire extinguishing system also includes an alarm module 10, which is electrically connected to the controller 1. The alarm module 10 includes an audible alarm and / or a light alarm.

[0056] The alarm module 10 is electrically connected to the controller 1. After the monitoring agency 2 detects a fire, it immediately triggers an alarm. The sound alarm quickly reminds people on the bridge to evacuate or stay away through sound and light signals. The light alarm can still clearly transmit alarm information during the day or in noisy environments, ensuring that the alarm effect is not affected by the environment.

[0057] A supply pipe 11 is provided between the storage tank 7 and the input end of the spraying device 4. A power mechanism is connected to the storage tank 7 to transport the foam or dry powder in the storage tank 7 to the spraying device 4. The power mechanism is electrically connected to the controller 1.

[0058] The supply pipe 11 establishes a stable transmission channel between the storage tank 7 and the spraying device 4, ensuring that the foam or dry powder does not leak or clog during transportation, thus guaranteeing the effective transmission of the extinguishing medium. The power mechanism provides sufficient thrust for the transportation of the extinguishing medium, solving the problem of poor transportation caused by the poor flowability of foam or dry powder, ensuring that the spraying device 4 can obtain extinguishing medium with sufficient pressure, and achieving large-area, long-distance spraying. The controller 1 automatically controls the start and stop of the power mechanism, enabling the spraying of foam or dry powder to accurately match the fire monitoring results, and to respond quickly to special fires such as oil and electrical fires, improving the extinguishing efficiency and effectiveness of special fires.

[0059] It also includes an emergency communication module and a processing module for identifying vehicle types from the collected images. The identified types include: cars, light trucks, medium trucks, large trucks, special vehicles, and engineering vehicles. The controller 1 determines the vehicle type and fire situation based on the identification results of the processing module, selects and activates the corresponding fire extinguishing equipment to execute the corresponding fire extinguishing strategy.

[0060] The emergency communication module includes a wireless intercom device installed on the side of the bridge, which can establish voice communication with the driver when the vehicle is identified as a special vehicle or a vehicle transporting flammable materials or dangerous goods.

[0061] For foam delivery structures, please refer to the foam fire extinguishing system and foam fire extinguishing method disclosed in Chinese Patent Application No. 202010906185.8.

[0062] For a dry powder conveying structure, please refer to the annular dry powder fire extinguishing hood system disclosed in Chinese Patent Application No. 201611193316.2.

[0063] The bridge 5 is equipped with a fire-fighting robot 12 to replace the automatic jet fire extinguishing device 3 and the spraying device 4. The bridge 5 is equipped with a slide rail 13 on the guardrail. The bottom of the fire-fighting robot 12 is equipped with a slide plate 15 that slides on the slide rail 13. A drive mechanism for driving the fire-fighting robot 12 to move is provided between the slide plate 15 and the slide rail 13. The automatic jet fire extinguishing device 3, the spraying device 4, and the fire extinguishing robot 12 constitute a fire extinguishing equipment. The fire extinguishing equipment is remotely or wired to a monitoring platform via WiFi. The fire extinguishing equipment is also remotely or wired to the monitoring agency 2 on the bridge 5, so that the fire extinguishing equipment is not only connected to the bridge's own monitoring platform but also linked with the fire department.

[0064] The slide 15 is equipped with a motor 14, the bridge 5 has a rack on the guardrail, and the bottom of the slide 15 is equipped with a rotating gear. The drive shaft of the motor 14 is connected to the gear, and the gear meshes with the rack to drive the fire extinguishing robot 12 to slide back and forth on the slide rail 13. The electrical control part of the fire extinguishing robot 12, the motor 14, and the monitoring mechanism 2 are respectively electrically connected to the controller 1 to drive the fire extinguishing robot 12 to move according to the monitoring status of the monitoring mechanism 2. The fire extinguishing robot 12 includes a spray head, a water pump, and a water hose reel. The output end of the water hose reel is connected to the spray head, the input end of the water hose reel is connected to the water pump outlet, and the water pump inlet is connected to a water source.

[0065] The fire-fighting robot 12 moves along the rails 13 of the guardrail via a sliding plate 15. Its drive mechanism provides flexible power, enabling it to quickly reach any fire source on the bridge 5, overcoming the location limitations of fixed fire-fighting devices. The fire-fighting robot 12 can at least replace the automatic jet fire-fighting device 3, saving costs. The fire-fighting equipment connects to the monitoring platform and monitoring agency 2 via WiFi, enabling real-time synchronization of fire information. The monitoring platform can remotely dispatch the fire-fighting robot 12 without on-site personnel operation, improving the safety and flexibility of fire-fighting.

[0066] The monitoring unit 2 uses temperature sensors, infrared imagers, cameras, heat source monitoring equipment, dual-wavelength / multi-band flame detectors, and temperature-sensing fiber optics to monitor the status of bridge 5 around the clock. It captures real-time fire information such as abnormal temperatures and flame signals and transmits it to controller 1. Simultaneously, it synchronizes the data to the monitoring platform via WiFi. Upon receiving the information, controller 1 quickly analyzes the fire type (ordinary fire, oil fire, electrical fire, etc.), location, and scale. If it is an ordinary fire, it immediately controls the water pump 602 of the water supply unit 6 to start. Water is transported to the automatic jet fire extinguishing device 3 via pipeline 601. The infrared locator and camera 303 of the automatic jet fire extinguishing device 3 accurately locate the fire source, and the spray nozzle 302 sprays extinguishing liquid in a directional manner. If it is a special fire, controller 1 activates the power mechanism of the storage tank 7, and foam or dry powder is transported to the spraying device 4 via supply pipe 11, initiating the spraying fire extinguishing process.

[0067] When a fire occurs, controller 1 simultaneously triggers the sound and light alarms of alarm module 10 to remind personnel to evacuate and vehicles to avoid the fire. The monitoring platform transmits the fire location, type, scale, bridge structure information, and real-time video to the fire department's emergency command system in real time, enabling fire department coordination. The fire department can obtain complete fire data without waiting for manual alarms, and based on this information, plan the optimal rescue route in advance, allocate appropriate rescue equipment and extinguishing agents, and communicate with the bridge management department in real time through a dedicated channel.

[0068] If remote intervention is required, staff can remotely activate the spraying device 4 via the back-end terminal 8; in case of automatic or remote system failure, the spraying device 4 can be activated manually via button 9. If the fire location is unusual, the monitoring platform can dispatch the fire-fighting robot 12, whose drive mechanism moves the sliding plate 15 along the rail 13, allowing the robot to precisely reach the fire source and flexibly switch fire-fighting methods to extinguish the fire. After the fire department's rescue vehicles arrive, they can coordinate with the system's automatic fire-fighting progress to conduct follow-up operations, forming a seamless closed loop of "automatic initial fire suppression + remote dispatch + professional fire department rescue," minimizing fire losses.
