Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cabin fire technology, specifically a cabin fire rapid suppression spray system. Background Technology
[0002] With the rapid growth of global demand for renewable energy, wind power has become a core component of the clean energy system. As the core compartment that houses key equipment such as generators, gearboxes, and transformers, the safety of wind turbine nacelles is directly related to power generation efficiency and equipment lifespan.
[0003] Since wind turbine nacelles are often unattended at high altitudes and generally lack efficient and reliable fire suppression systems, fires often lead to catastrophic consequences due to the inability to respond in time. Therefore, we propose a rapid fire suppression spray system for wind turbine nacelles. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a rapid fire suppression spray system for engine room fires, comprising an engine room body, electrical equipment installed within the engine room body, an infrared thermal imaging array installed within the engine room body, an infrared flame detector and a gas sensor installed within the engine room body, the infrared thermal imaging array, the infrared flame detector and the gas sensor being electrically connected, a fire extinguishing assembly installed on the engine room body, and a fire extinguishing delivery component installed within the engine room body, the fire extinguishing delivery component being connected to the fire extinguishing assembly via a delivery pipe.
[0005] The fire extinguishing conveyor includes a first arc-shaped conveyor and a second arc-shaped conveyor. The arc curvature radius of the first arc-shaped conveyor and the second arc-shaped conveyor match the curvature of the inner wall of the cabin body. The two are attached and fixed to the inner wall of the cabin body. The axes of the first arc-shaped conveyor and the second arc-shaped conveyor are perpendicular to each other, and the intersection point is located in the top center area of the inner wall of the cabin. Nozzles are provided on the first arc-shaped conveyor and the second arc-shaped conveyor.
[0006] Preferably, the fire extinguishing assembly includes a first fire extinguishing agent chamber and a second fire extinguishing agent chamber. The first and second fire extinguishing agent chambers are respectively connected to a delivery pipe via pipelines. The first fire extinguishing agent chamber contains perfluorohexanone, and the second fire extinguishing agent chamber contains a water mist fire extinguishing agent. The water mist fire extinguishing agent is a mixture of deionized water and a surfactant. Perfluorohexanone is a clean and efficient fire extinguishing agent with advantages such as fast fire extinguishing speed and no pollution to equipment, making it suitable for extinguishing electrical fires and precision equipment fires. The water mist fire extinguishing agent uses the cooling, suffocation, and emulsification effects of water mist to extinguish fires. It is environmentally friendly and leaves little residue after extinguishing, making it suitable for extinguishing various types of fires. This design allows the two fire extinguishing agents to be delivered to the fire extinguishing delivery component through the delivery pipe as needed, achieving simultaneous or timed spraying, fully utilizing the advantages of the two fire extinguishing agents, and improving the fire extinguishing effect.
[0007] Preferably, the nozzles are multiple and are evenly distributed circumferentially along the outer surfaces of the first and second arc-shaped conveyors. This ensures that the extinguishing agent is evenly sprayed inside the cabin, allowing it to cover all areas of the cabin, including critical components such as electrical equipment, thereby more effectively suppressing the spread of fire.
[0008] Preferably, the cross-section of the first arc-shaped conveyor and the second arc-shaped conveyor is a hollow tubular structure with an internal extinguishing agent flow channel, which facilitates the flow of the extinguishing agent inside the conveyor and ensures that the extinguishing agent can smoothly pass through the conveyor to reach the nozzle and be sprayed out from the nozzle.
[0009] Preferably, the intersection of the first arc-shaped conveyor and the second arc-shaped conveyor is connected to the conveying pipe, so that the extinguishing agent can smoothly enter the first arc-shaped conveyor and the second arc-shaped conveyor from the conveying pipe.
[0010] Preferably, the cabin body is equipped with an alarm, which improves the system's safety and emergency response capabilities, and can promptly notify relevant personnel in the early stages of a fire, reducing potential losses caused by the fire.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] During operation, the control unit receives signals from the infrared thermal imaging array, infrared flame detector, and gas sensor. It then performs comprehensive analysis and processing of these signals. If multiple detectors simultaneously or sequentially issue fire signals, the control unit determines that the likelihood of a fire is high and immediately activates the alarm. After confirming the fire, the control unit simultaneously activates the fire extinguishing components. The first and second fire extinguishing agent chambers begin operating, delivering perfluorohexanone and water mist fire extinguishing agents through pipelines to the delivery pipe. The delivery pipe then delivers the two fire extinguishing agents to the fire extinguishing delivery component. The fire extinguishing agent flow channels inside the first and second arc-shaped delivery components guide the fire extinguishing agents to the nozzles. The nozzles spray the two fire extinguishing agents into the cabin in a mist form. Due to the combined effect of the first and second arc-shaped delivery components... The axes of the arc-shaped conveyor components are perpendicular to each other, and the intersection point is located in the top center area of the cabin interior wall. The extinguishing agent sprayed from the nozzles can evenly cover all areas inside the cabin, including critical parts such as electrical equipment. The sensor unit continues to monitor changes in temperature, flame, and gas concentration inside the cabin in real time and transmits the data to the control unit. The control unit determines whether the fire has been completely extinguished based on the monitoring data. When the fire is completely extinguished, the control unit sends a reset signal to stop the operation of the extinguishing components and alarms. The system is manually inspected and maintained to ensure that it returns to normal working condition and prepares for the next possible fire. It can quickly and accurately detect fires and use the combined spraying of two extinguishing agents to rapidly suppress fires and protect the safety of personnel and equipment inside the cabin.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] Depend on Figure 1 The present invention includes a cabin body 1, an electrical device 2, an infrared thermal imaging array 10, an infrared flame detector 11, and a gas sensor 12, all electrically connected. A fire extinguishing assembly 3 is mounted on the cabin body 1, and a fire extinguishing delivery device 4 is located within the cabin body 1. The fire extinguishing delivery device 4 is connected to the fire extinguishing assembly 3 via a delivery pipe 5.
[0018] The fire extinguishing conveyor 4 includes a first arc-shaped conveyor 6 and a second arc-shaped conveyor 7. The arc curvature radius of the first arc-shaped conveyor 6 and the second arc-shaped conveyor 7 matches the curvature of the inner wall of the cabin body 1. The two are attached and fixed to the inner wall of the cabin body 1. The axes of the first arc-shaped conveyor 6 and the second arc-shaped conveyor 7 are perpendicular to each other, and the intersection point is located in the top center area of the inner wall 3 of the cabin. Nozzles 8 are provided on the first arc-shaped conveyor 6 and the second arc-shaped conveyor 7.
[0019] The fire extinguishing assembly 3 includes a first fire extinguishing agent chamber 9 and a second fire extinguishing agent chamber 14. The first fire extinguishing agent chamber 9 and the second fire extinguishing agent chamber 14 are respectively connected to the delivery pipe 5 through pipelines. The first fire extinguishing agent chamber 9 contains perfluorohexanone, and the second fire extinguishing agent chamber 14 contains water mist fire extinguishing agent. The water mist fire extinguishing agent is a mixture of deionized water and surfactant. Perfluorohexanone is a clean and efficient fire extinguishing agent with advantages such as fast fire extinguishing speed and no pollution to equipment. It is suitable for extinguishing electrical fires and precision equipment fires. The water mist fire extinguishing agent uses the cooling, suffocation and emulsification effects of water mist to extinguish fires. It is environmentally friendly and leaves little residue after extinguishing fires. It is suitable for extinguishing various types of fires. This design allows the two fire extinguishing agents to be delivered to the fire extinguishing delivery component through the delivery pipe as needed, so as to achieve simultaneous or timed spraying, give full play to the advantages of the two fire extinguishing agents, and improve the fire extinguishing effect.
[0020] The nozzle 8 has multiple nozzles, which are evenly distributed circumferentially along the outer surface of the first arc-shaped conveyor 6 and the second arc-shaped conveyor 7. This ensures that the extinguishing agent is evenly sprayed in the engine room, allowing the extinguishing agent to cover all areas in the engine room, including critical parts such as electrical equipment, thereby more effectively suppressing the spread of fire.
[0021] The first arc-shaped conveyor 6 and the second arc-shaped conveyor 7 have a hollow tubular cross-section and are provided with extinguishing agent flow channels inside, which facilitates the flow of extinguishing agent inside the conveyor and ensures that the extinguishing agent can smoothly pass through the conveyor to reach the nozzle and be sprayed out from the nozzle.
[0022] The intersection of the first arc-shaped conveyor 6 and the second arc-shaped conveyor 7 is connected to the conveying pipe 5, so that the extinguishing agent can smoothly enter the first arc-shaped conveyor and the second arc-shaped conveyor from the conveying pipe.
[0023] An alarm 13 is installed on the main body of the cabin, which improves the safety and emergency response capabilities of the system and can promptly notify relevant personnel in the early stages of a fire, reducing the potential losses caused by the fire.
[0024] Working Principle: During operation, the control unit receives signals from the infrared thermal imaging array 10, the infrared flame detector 11, and the gas sensor 12. These signals are comprehensively analyzed and processed. If multiple detectors simultaneously or sequentially issue fire signals, the control unit determines that the probability of a fire is high and immediately activates the alarm 13. After confirming the fire, the control unit simultaneously activates the fire extinguishing assembly 3. The first and second fire extinguishing agent chambers 9 begin operation, delivering perfluorohexanone and water mist fire extinguishing agents through pipelines to the delivery pipe 5. The delivery pipe 5 delivers the two fire extinguishing agents to the fire extinguishing delivery component 4. The fire extinguishing agent flow channels inside the first arc-shaped delivery component 6 and the second arc-shaped delivery component 7 of the fire extinguishing delivery component 4 guide the fire extinguishing agents to the nozzle 8. The nozzle 8 sprays the two fire extinguishing agents into the cabin in a mist form. The axes of the first and second arc-shaped conveyors are perpendicular to each other, and their intersection point is located in the top center area of the cabin's inner wall. The extinguishing agent sprayed from the nozzles can evenly cover all areas inside the cabin, including critical parts such as electrical equipment 2. The sensor unit continues to monitor changes in temperature, flame, and gas concentration inside the cabin in real time and transmits the data to the control unit. The control unit determines whether the fire has been completely extinguished based on the monitoring data. When the fire is completely extinguished, the control unit sends a reset signal to stop the operation of the extinguishing components and alarms. The system is manually inspected and maintained to ensure that it returns to normal working condition and prepares for the next possible fire. It can quickly and accurately detect fires and use the combined spraying of two extinguishing agents to rapidly suppress fires and protect the safety of personnel and equipment inside the cabin.
