Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to an outdoor electrical cabinet fire protection device. Background Technology

[0002] According to Chinese patent application CN220443081U, a fire cylinder fixing device for an outdoor energy storage cabinet includes an outdoor energy storage battery cabinet. The cabinet has an internal frame positioned in the middle, dividing the cabinet's interior into two parts. Two sets of frames are provided, forming a cavity between them after installation. The fixing device is located within this cavity and includes a base with at least one set of clamps. The fire cylinder is fixed to the base via these clamps. A sliding groove is provided within the cavity, allowing the base to slide within it. By engaging the fire cylinder with the sliding groove in the frame via the base, a drawer-like structure is formed. This not only facilitates the installation and maintenance of the fire cylinder but also saves considerable space within the outdoor energy storage battery cabinet. Furthermore, this fire cylinder fixing device can be adjusted by changing the positions of the front and rear clamps to provide a precise positioning function for the fire cylinder, thus better satisfying the need for fixed placement.

[0003] According to Chinese patent application CN113813542B, a multi-linkage fire control method, device, and outdoor cabinet system relate to the field of fire protection technology. The multi-linkage fire control method includes controlling the activation of corresponding fire-fighting equipment when the energy storage battery cabinet meets thermal runaway conditions; obtaining the capacity value of the extinguishing agent in the fire-fighting equipment; determining whether the capacity value is less than or equal to a first preset value; if the capacity value is less than or equal to the first preset value, then controlling the activation of any one of multiple control valves to transport the extinguishing agent from other fire-fighting equipment to the fire-fighting equipment corresponding to the energy storage battery cabinet that meets the thermal runaway conditions, thereby delivering extinguishing agent to the energy storage battery cabinet that meets the thermal runaway conditions. This enables timely control of fires occurring in the energy storage battery cabinet and improves the overall fire control capability of the outdoor cabinet.

[0004] The aforementioned patent documents and prior art have the following technical problems when used:

[0005] Problem 1: Common outdoor power distribution cabinet fire protection equipment may occupy a large space in non-fire conditions, affecting the installation and maintenance of the power distribution cabinet and the normal activities of surrounding personnel and equipment. In addition, traditional outdoor power distribution cabinet fire protection devices may not be able to fully and accurately extinguish fire sources at different heights and locations inside the power distribution cabinet, making it easy for the fire to spread.

[0006] Problem 2: Previous fire-fighting devices may have delays in fire monitoring and fire extinguishing procedures, and they cannot be adjusted to extinguish fires in a targeted manner, resulting in waste of fire-fighting materials. Some existing fire-fighting devices do not effectively recycle fire-fighting materials, which leads to material waste and is easy to cause environmental pollution, and is not conducive to practical use.

[0007] Thirdly, traditional fire protection systems often cannot adapt well to the different numbers and locations of electrical distribution cabinets. When faced with complex outdoor electrical cabinet layouts, they may not be able to provide effective fire protection. Summary of the Invention

The interior of the rotating fire extinguishing arm is a hollow structure. A second mounting groove is provided at one end of the fire track near the angle adjusting arm. A storage box is provided inside the second mounting groove. A guide pipe is connected to the side of the storage box, and the top end of the guide pipe penetrates into the interior of the U-shaped spray chamber.

[0016] Preferably, a first electrically controlled valve is embedded in the inner wall of the end of the U-shaped spray chamber away from the angle adjustment motor, and a second electrically controlled valve is embedded on both sides of the end of the rotating fire extinguishing arm near the electric shaft, and the second electrically controlled valve is electrically connected to the first electrically controlled valve.

[0017] Preferably, the fire-fighting rail is provided with a negative pressure recovery chamber, the bottom surface of the storage recovery trough is provided with a straight array of negative pressure holes, and the negative pressure holes penetrate into the interior of the negative pressure recovery chamber. The side of the fire-fighting rail away from the second installation trough is provided with a first installation trough, the first installation trough is provided with an air pump, the surface of the air pump is connected with an air guide pipe, and the end of the air guide pipe penetrates into the end of the negative pressure recovery chamber.

[0018] Preferably, splicing grooves are provided on both sides of the top surface of the fire-fighting rail, splicing strips are provided on both sides of the bottom surface of the fire-fighting rail, and the splicing strips are fitted with the splicing grooves with a gap. A limiting block is provided at one end of the fire-fighting rail, and a limiting groove is provided at the other end of the fire-fighting rail, and the limiting groove is fitted with the limiting strip with a gap.

[0019] Preferably, the end section of the fire-fighting rail is an inverted convex structure, the width of the item collection trough is the same as the width of the bottom end of the fire-fighting rail, and the depth of the item collection trough is twice the height of the bottom end of the fire-fighting rail. The thickness of the linear fire-fighting arm is half the depth of the item collection trough, and the width of the linear fire-fighting arm is the same as the width of the inner wall of the item collection trough.

[0020] Preferably, the splicing strip is located on both sides of the bottom end of the fire-fighting rail, and the positions of the splicing strip and the splicing groove are corresponding in the vertical direction. The two ends of the splicing groove are blind grooves, and the two ends of the storage and recycling groove penetrate through the two ends of the fire-fighting rail.

[0021] Preferably, a set of controllers is externally connected to the fire-fighting rail, and the controllers are electrically connected to the angle adjustment motor, the air pump, the electric shaft, the telescopic cylinder, the first solenoid valve, and the second solenoid valve. Temperature sensors and smoke detectors are provided on both the inner and outer walls of the main body of the distribution cabinet, and the temperature sensors and smoke detectors are located at multiple positions on the side of the main body of the distribution cabinet. At least one set of infrared cameras electrically connected to the angle adjustment motor via the controller is provided on the outside of the installation position of the main body of the distribution cabinet, and the temperature sensors and smoke detectors are electrically connected to the angle adjustment motor via the controller.

[0022] Preferably, the operation process of the controller externally connected to the fire-fighting rail is as follows:

[0023] Sp1: Monitoring and Early Warning: Temperature sensors on the inner and outer walls of the main body of the distribution cabinet and smoke detectors continuously monitor the internal environment of the distribution cabinet. When the temperature or smoke concentration reaches the preset alarm threshold, the temperature sensors and smoke detectors send signals to the controller.

[0024] Sp2: Start-up and preparation: After receiving the alarm signal, the controller starts the control system of the entire fire-fighting device and sends a command to the angle adjustment motor. The angle adjustment motor drives the linear fire-fighting arm to open from inside the storage and recovery tank, so that the linear fire-fighting arm is in the initial position ready to extinguish the fire.

[0025] Sp3: Material Supply and Transfer: The controller controls the storage tank to guide the fire extinguishing material into the U-shaped spray chamber through the guide pipe, providing the material required for fire extinguishing for the linear fire extinguishing arm and the rotating fire extinguishing arm. For the rotating fire extinguishing arm, when the second solenoid valve at the end of the rotating fire extinguishing arm coincides with the first solenoid valve, the controller controls the opening of these two solenoid valves, so that the U-shaped spray chamber and the cavity inside the rotating fire extinguishing arm are connected, realizing the transfer of material into the rotating fire extinguishing arm. After the material supply is completed, the controller controls both valves to close.

[0026] SP4: Fire Extinguishing Operation: The spray nozzles on the surfaces of the linear and rotary fire extinguishing arms begin to spray extinguishing materials for fire suppression. Simultaneously, the controller controls the telescopic cylinder to push the rotary fire extinguishing arm out from inside the linear fire extinguishing arm and controls the electric shaft to drive the rotary fire extinguishing arm to rotate. Through the spray nozzles, the fire extinguishing is carried out in the high-altitude area, expanding the fire suppression coverage area. The controller adjusts the angle and working status of the motor, electric shaft, and telescopic cylinder in real time based on information from temperature sensors, smoke detectors, and infrared cameras to ensure the fire suppression effect. For example, according to the location and range of the fire, the angle and position of the linear and rotary fire extinguishing arms are precisely adjusted so that the spray nozzles can accurately aim at the fire source for efficient fire suppression.

[0027] SP5: Material Recovery: During the fire extinguishing process, the controller starts the air pump, which recovers the sprayed material under negative pressure through the air pipe and negative pressure hole to prevent the material from accumulating around the main body of the power distribution cabinet, thereby reducing environmental pollution and the impact on the normal operation of the equipment.

[0028] SP6: Fire Extinguishing End and Reset: When the temperature sensor and smoke alarm detect that the temperature and smoke concentration inside the main body of the distribution cabinet have returned to normal, that is, after the fire has disappeared, the controller controls the angle adjustment motor to retract the linear fire extinguishing arm into the storage recovery tank, and at the same time controls the telescopic cylinder to retract the rotating fire extinguishing arm into the linear fire extinguishing arm, so that the entire fire protection device returns to its initial state and waits for the next fire monitoring and alarm.

[0029] Beneficial effects:

[0030] This invention provides an outdoor electrical cabinet fire-fighting device. It has the following beneficial effects:

[0031] 1. This invention features highly efficient fire extinguishing capabilities and optimized space utilization. An angle-adjusting motor drives the linear fire extinguishing arm to adjust its angle, while the rotating fire extinguishing arm, in conjunction with a telescopic cylinder and an electric shaft, achieves extension and rotation. This allows the spray nozzles to cover different positions and heights within the electrical cabinet, effectively extinguishing fires from both lower locations and higher areas. This significantly improves the comprehensiveness and precision of fire suppression, effectively preventing the spread of fire. The device relies on temperature sensors and smoke detectors installed inside and outside the electrical cabinet for real-time monitoring. Upon detecting any abnormalities, it quickly transmits signals to the controller. This allows for rapid activation of the entire fire-fighting system, enabling timely response and handling of fires. When not in use, the linear fire-fighting arm can be stored in the storage and recycling slot of the fire-fighting rail, and the rotating fire-fighting arm can also be retracted into the linear fire-fighting arm. The entire fire-fighting system is in a retracted state when not in a fire, without occupying additional space around the distribution cabinet. This ensures the smooth installation and maintenance of the distribution cabinet and eliminates the need to reserve a large operating space for the fire-fighting system. This makes the daily maintenance and repair of the distribution cabinet more convenient and efficient, and also avoids obstructing personnel passage and equipment operation around the distribution cabinet due to the presence of the fire-fighting system. This improves the space utilization and work convenience of outdoor distribution cabinet locations.

[0032] 2. This invention employs an air pump in conjunction with an air duct and negative pressure orifice to recover the sprayed fire extinguishing material under negative pressure. This allows the material to be collected and, after appropriate treatment, reused in fire extinguishing operations, achieving material recycling, reducing the consumption of fire extinguishing materials, lowering fire protection costs, and aligning with the concepts of environmental protection and sustainable development. By recovering the fire extinguishing material, it prevents the material from being scattered and accumulated around the power distribution cabinet, preventing pollution of the surrounding soil, water bodies, and other environments due to material residue, thus protecting the ecological environment. Especially in outdoor use scenarios, it helps maintain the cleanliness and stability of the surrounding natural environment, promoting green development, saving natural resources, and reducing the maintenance costs of the natural environment.

[0033] 3. This invention utilizes fire-fighting rails that can be vertically stacked when not in use, saving transport space. When in use, depending on the location and requirements of the distribution cabinet, it can be assembled into polygonal shapes such as squares, pentagons, and hexagons, or even circular or racetrack-shaped structures. This flexible assembly method allows the device to adapt to different numbers and distribution locations of distribution cabinets. Whether it's a single distribution cabinet or a cluster of multiple cabinets, it provides appropriate fire protection, greatly improving the device's versatility and practicality. It can meet various complex outdoor distribution cabinet layout scenarios. Under the unified management of the controller, all components of the fire-fighting device can be flexibly adjusted and work collaboratively according to the actual situation at the fire scene. For example, based on the size of the fire, its spread direction, and the specific structure of the distribution cabinet, the controller can precisely control the actions of components such as angle adjustment motors, telescopic cylinders, and electric shafts, optimizing the fire-fighting strategy and ensuring optimal fire-fighting effects in different fire scenarios. This effectively addresses various complex and changing fire situations, providing reliable fire safety guarantees for the distribution cabinet. Attached Figure Description

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figures 1 to 19As shown, an outdoor electrical cabinet fire-fighting device includes a distribution cabinet body 1 and fire-fighting rails 2. Multiple identical fire-fighting rails 2, connected end-to-end, are provided on the external side of the distribution cabinet body 1. The distribution cabinet body 1 is used to house and protect electrical equipment and is the core component of the entire power distribution system. It is also the object protected by the fire-fighting device, preventing damage to its internal electrical components from fire and ensuring the stability and safety of the power supply. The fire-fighting rails 2 serve as the supporting structure and installation foundation for the entire fire-fighting device, providing stable installation positions and running tracks for components such as the linear fire-fighting arm 17, the angle adjustment motor 16, the rotating fire-fighting arm 21, the storage box 14, and the air pump 11. This ensures that each component can accurately perform its function and work together to complete the fire-fighting task. Its internal negative pressure recovery chamber 8 and material recovery trough 5 are used for the recovery of fire-fighting materials and the storage of the fire-fighting arm, respectively, realizing the recycling of materials and optimized space utilization, thus improving the environmental friendliness and practicality of the device.

[0057] A storage and recovery trough 5 is provided on the top surface of the fire-fighting rail 2. A linear fire-fighting arm 17 is located at one end of the storage and recovery trough 5. In non-fire conditions, the storage and recovery trough 5 is used to store the linear fire-fighting arm 17, allowing it to be neatly concealed inside the fire-fighting rail 2, avoiding the occupation of additional space and ensuring the cleanliness and unobstructed space around the main body of the distribution cabinet 1. This facilitates the installation and maintenance of other equipment and the operation and passage of personnel. In the event of a fire, it provides the necessary space and guidance for the extension of the linear fire-fighting arm 17, ensuring that the linear fire-fighting arm 17 can quickly and accurately reach the predetermined fire-fighting position and smoothly carry out fire-fighting operations. It also protects the linear fire-fighting arm 17 from external environmental damage when not in use, extending its service life. An angle adjustment motor 16 is connected to the end of the arm 17. An adjustment groove 19 is located near the center inside the linear fire extinguishing arm 17. A rotating fire extinguishing arm 21 slides inside the adjustment groove 19. A telescopic cylinder 23 is bolted to the bottom surface of the adjustment groove 19. An electric shaft 24 is connected to the movable end of the telescopic cylinder 23, and the end of the electric shaft 24 is connected to the bottom end of the rotating fire extinguishing arm 21. Both the rotating fire extinguishing arm 21 and the linear fire extinguishing arm 17 have spray holes 22 on their surfaces. The linear fire extinguishing arm 17 can be straight or curved; the term "straight" in its name means that the fire extinguishing material is sprayed in a straight line, i.e., in the fire extinguishing state, and does not restrict the shape of the fire extinguishing arm. The "rotating" in the rotating fire extinguishing arm 21 has the same meaning, indicating that it is in a rotating state. The linear fire extinguishing arm 17, as one of the main components for fire extinguishing operations, sprays extinguishing materials onto the fire source of the electrical cabinet body 1 through spray holes 22 on its surface, directly extinguishing the fire and preventing its spread. During the fire extinguishing process, the angle adjustment motor 16 can adjust its angle to accurately extinguish fire sources at different directions and heights, improving the effectiveness and range of fire extinguishing and ensuring that all parts of the electrical cabinet body 1 are effectively protected by fire extinguishing. The extinguishing materials in the storage tank 14 are transported to the U-shaped spray chamber through the guide pipe 15, and then evenly sprayed out from the spray holes 22 on the surface of the linear fire extinguishing arm 17, forming an extinguishing jet to cover and extinguish the fire source. The angle adjustment of arm 17 is achieved through angle adjustment motor 16. The controller continuously adjusts the angle of angle adjustment motor 16 and the material conveying volume of storage tank 14 to ensure the maximization of fire extinguishing effect. If the fire is large and the fire extinguishing range needs to be expanded, the controller will activate telescopic cylinder 23 to push the rotating fire extinguishing arm 21 to extend from the adjustment groove 19 of the linear fire extinguishing arm 17, further increasing the height and range of fire extinguishing, and driving the linear fire extinguishing arm 17 to rotate within a certain range, thereby adjusting the spray direction of the spray nozzle 22 so that it can be aimed at different positions of the fire source to achieve multi-angle fire extinguishing. After the fire is extinguished, the controller controls the linear fire extinguishing arm 17 to stop spraying material and slowly retracts it into the storage and recovery tank 5 to restore it to its initial state.

[0058] The adjusting groove 19 provides a sliding track and support structure for the rotating fire extinguishing arm 21, enabling it to extend and retract within the linear fire extinguishing arm 17. This changes the height and range of the fire extinguishing action, allowing for effective suppression of fires at different heights and improving the fire extinguishing capability and adaptability of the fire-fighting device. The movable end of the telescopic cylinder 23 is connected to the bottom end of the rotating fire extinguishing arm 21. When the telescopic cylinder 23 receives a command from the controller, its piston rod extends and retracts, pushing the rotating fire extinguishing arm 21 to slide up and down along a predetermined track within the adjusting groove 19. This allows the rotating fire extinguishing arm 21 to extend and retract, changing its position and height relative to the linear fire extinguishing arm 17, thereby adjusting the range and height of the fire extinguishing action. In non-fire conditions, the rotating fire extinguishing arm 21 is retracted within the adjusting groove 19 of the linear fire extinguishing arm 17, and the piston rod of the telescopic cylinder 23 is also retracted. When a fire breaks out and becomes large, requiring an expansion of the firefighting range and height, the controller sends a start signal to the telescopic cylinder 23. The piston rod of the telescopic cylinder 23 extends, pushing the rotating fire extinguishing arm 21 upwards along the adjusting groove 19, gradually extending from the straight fire extinguishing arm 17 until it reaches the predetermined fire extinguishing height and stops. During the firefighting process, the telescopic cylinder 23 can adjust the extension length of the piston rod in real time according to changes in the fire and instructions from the controller, thereby changing the height of the rotating fire extinguishing arm 21 to ensure effective extinguishing of fire sources at different heights. After the fire is extinguished, the controller sends a retraction signal to the telescopic cylinder 23. The piston rod of the telescopic cylinder 23 retracts, slowly pulling the rotating fire extinguishing arm 21 back into the adjusting groove 19, restoring it to its initial retracted state, ready to be activated again for the next fire.

[0059] The rotating fire extinguishing arm 21 and the linear fire extinguishing arm 17 work together to form a multi-level, multi-angle fire extinguishing system, which can adapt to the main body of the power distribution cabinet 1 of different shapes and sizes as well as complex and ever-changing fire situations, thus enhancing the versatility and practicality of the fire-fighting equipment.

[0060] The electric shaft 24 provides rotational power to the rotating fire extinguishing arm 21, enabling it to rotate 360 ​​degrees horizontally. This allows for the even distribution of extinguishing materials over a wider area, achieving comprehensive fire suppression of fire sources in different directions around the main body of the distribution cabinet 1. This further expands the fire suppression coverage area of ​​the fire-fighting device and improves the fire suppression effect. The electric shaft 24 typically consists of a motor, a reducer, a coupling, and an output shaft. When the controller sends a rotation command to the electric shaft 24, the motor starts running. The reducer converts the high-speed rotation of the motor into a low-speed, high-torque output suitable for the rotation of the rotating fire extinguishing arm 21. The torque is then transmitted to the output shaft via the coupling, driving the rotating fire extinguishing arm 21 to rotate around the output shaft. The rotational speed and direction of the electric shaft 24 can be precisely controlled by the controller according to the actual situation at the fire scene. By adjusting the motor's speed and direction, the rotating fire extinguishing arm 21 can rotate quickly and accurately, enabling it to spray extinguishing materials to the fire source that needs to be extinguished, forming an effective fire suppression coverage area.

[0061] The design of the nozzle 22 typically takes into account fluid dynamics principles. Its aperture size, shape, and distribution are optimized to ensure that the extinguishing material can form a stable and uniform jet during the spraying process. When the extinguishing material enters the nozzle 22 under pressure, the flow velocity of the material increases due to the throttling effect of the nozzle 22. Pressure energy is converted into kinetic energy, thereby causing the extinguishing material to be ejected at high speed and rush towards the fire source to achieve the purpose of extinguishing the fire.

[0062] A U-shaped spray chamber 18 is provided between the outer wall of the adjusting slide 19 and the inner wall of the linear fire extinguishing arm 17. The spray holes 22 on the surface of the linear fire extinguishing arm 17 penetrate into the interior of the U-shaped spray chamber 18. The interior of the rotating fire extinguishing arm 21 is a hollow structure. A second mounting groove 13 is provided at one end of the fire rail 2 near the angle adjusting arm. A storage box 14 is provided inside the second mounting groove 13. A guide pipe 15 is connected to the side of the storage box 14, and the top end of the guide pipe 15 communicates with the interior of the U-shaped spray chamber 18. The storage box 14 is used to store the materials required for fire extinguishing and is a fire extinguishing device. The equipment's material storage warehouse ensures a continuous and sufficient supply of extinguishing materials for the linear fire extinguishing boom 17 and the rotating fire extinguishing boom 21 during a fire, guaranteeing the smooth progress of fire extinguishing operations. It is an important material basis for the fire-fighting equipment to realize its fire extinguishing function. The guide pipe 15 serves as a channel for transporting extinguishing materials from the storage tank 14 to the U-shaped spray chamber, ensuring that the extinguishing materials can be smoothly and stably transferred from the storage tank 14 to the linear fire extinguishing boom 17 under pressure, providing a continuous supply of materials to the spray nozzle 22, and ensuring the continuity and effectiveness of fire extinguishing operations.

[0063] A first electrically controlled valve 20 is embedded in the inner wall of the U-shaped spray chamber 18 at the end furthest from the angle adjustment motor 16. A second electrically controlled valve 25 is embedded on both sides of the rotating fire extinguishing arm 21 near the electric shaft 24, and the second electrically controlled valve 25 is electrically connected to the first electrically controlled valve 20. The U-shaped spray chamber serves as a temporary storage and distribution channel for fire extinguishing materials in the linear fire extinguishing arm 17, evenly distributing the fire extinguishing materials transported from the storage tank 14 to the spray holes 22 on the surface of the linear fire extinguishing arm 17. This ensures that the spray holes 22 can continuously and stably spray fire extinguishing materials, effectively extinguishing the fire source. It also acts as a bridge connecting the storage tank 14 and the spray holes 22, ensuring the smoothness and stability of the fire extinguishing materials during transportation. At the same time, it provides a certain space and conditions for adjusting the flow and pressure of the fire extinguishing materials, which helps to improve the fire extinguishing performance of the fire-fighting device.

[0064] When the fire-fighting device is in standby mode, the first electrically controlled valve 20 is closed, and there is no extinguishing material in the U-shaped spray chamber. When a fire occurs and the controller activates the fire-fighting device, the pressure valve inside the feed pipe 15 is opened first. The extinguishing material in the storage tank 14 enters the U-shaped spray chamber under pressure through the feed pipe 15, and is then evenly distributed to each spray hole 22 to begin spraying for fire extinguishing. During the fire extinguishing process, the controller adjusts the opening of the pressure valve in real time based on the size of the fire, feedback information from the temperature sensor and the smoke alarm, to control the flow rate and pressure of the extinguishing material entering the U-shaped spray chamber to adapt to different fire extinguishing needs. After the fire is extinguished, the controller closes the pressure valve to stop the material delivery. The remaining material in the U-shaped spray chamber can be recycled through a corresponding recovery device, such as connecting to the negative pressure recovery chamber 8, and is ready to be used again when the next fire occurs.

[0065] The fire-fighting rail 2 has a negative pressure recovery chamber 8 inside. The bottom surface of the storage recovery trough 5 has a linear array of negative pressure holes 9, which penetrate the interior of the negative pressure recovery chamber 8. A first installation groove 10 is located on the side of the fire-fighting rail 2 away from the second installation groove 13. An air extraction pump 11 is installed inside the first installation groove 10. An air guide pipe 12 is connected to the surface of the air extraction pump 11, and its end penetrates the end of the negative pressure recovery chamber 8. The negative pressure recovery chamber 8, through its interaction with the negative pressure holes 9 on the bottom surface of the storage recovery trough 5 and the air guide pipe 12 connected to the air extraction pump 11, generates a negative pressure environment under the action of the air extraction pump 11, drawing back the materials sprayed during the fire extinguishing process into the negative pressure recovery chamber 8 for collection and subsequent processing. The negative pressure recovery chamber 8 is used to collect and recover the extinguishing materials sprayed during the fire extinguishing process, realizing the recycling of extinguishing materials, reducing material waste and environmental pollution. It also helps maintain the cleanliness and safety of the environment around the main body of the distribution cabinet 1, reducing the risk of secondary accidents caused by material residue. The negative pressure recovery chamber 8 is located inside the fire-fighting rail 2 and works in conjunction with the negative pressure holes 9 on the bottom of the material recovery trough 5 and the air duct 12 connected to the air pump 11. When the air pump 11 is started, a negative pressure environment is formed in the negative pressure recovery chamber 8. Under the action of negative pressure, the materials sprayed during the fire extinguishing process are sucked into the negative pressure recovery chamber 8 through the negative pressure holes 9 for collection. The internal structure design of the negative pressure recovery chamber 8 is conducive to the sedimentation and aggregation of materials. For example, it may be equipped with baffles, filters, and other devices to allow the sucked-in materials to be distributed and deposited in an orderly manner within the chamber, facilitating subsequent recycling.

[0066] The negative pressure hole 9 serves as the inlet for fire extinguishing materials to enter the negative pressure recovery chamber 8. It works in conjunction with the negative pressure recovery chamber 8 and the air pump 11. Under the negative pressure generated by the air pump 11, the fire extinguishing materials scattered on the bottom and surrounding surface of the material recovery tank 5 during the fire extinguishing process are sucked into the negative pressure recovery chamber 8, thereby realizing the recovery of materials. It is a key component of the material recovery system.

[0067] The air extraction pump 11 is typically a centrifugal, piston, or vacuum pump, and its working principle is based on the gas suction and compression mechanism. When the air extraction pump 11 starts, the motor drives the impeller or piston and other components to rotate at high speed, creating a negative pressure zone at the pump's inlet. Outside air is drawn into the pump under the pressure difference and then discharged through the exhaust port. In the material recovery system used in fire-fighting equipment, the air inlet of the air extraction pump 11 is connected to the negative pressure recovery chamber 8 via a guide pipe 12, while the exhaust port is open to the outside atmosphere. As the pump continues to run, air is continuously extracted from the negative pressure recovery chamber 8, and the pressure gradually decreases, thus creating a sufficient pressure difference between the inside and outside of the chamber, prompting the extinguishing material to enter the recovery chamber through the negative pressure port 9. Specific Implementation Example 2:

[0069] like Figures 1 to 19 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0070] During handling or transportation, the entire fire-fighting rail 2 is vertically stacked using splicing strips 3 and splicing grooves 4, reducing space occupation and facilitating handling. The end cross-section of the fire-fighting rail 2 is an inverted convex structure. The width of the storage and recovery trough 5 is the same as the bottom width of the fire-fighting rail 2, and the depth of the storage and recovery trough 5 is twice the height of the bottom of the fire-fighting rail 2. The thickness of the linear fire-fighting arm 17 is half the depth of the storage and recovery trough 5, and the width of the linear fire-fighting arm 17 is the same as the width of the inner wall of the storage and recovery trough 5. This dimensional design allows the linear fire-fighting arm 17 to be tightly embedded in the storage and recovery trough 5, and... During extension and retraction, it can move smoothly along the groove wall without jamming or deviation. The splicing strip 3 is located on both sides of the bottom end of the fire rail 2, and the positions of the splicing strip 3 and the splicing groove 4 correspond in the vertical direction. The two ends of the splicing groove 4 are blind grooves. The two ends of the storage and recovery groove 5 are connected to the two ends of the fire rail 2. Through the through structure at both ends of the storage and recovery groove 5, it is ensured that the linear fire extinguishing arm 17 is not obstructed during extension and retraction and can be fully extended to the predetermined fire extinguishing position. At the same time, it is also convenient for the linear fire extinguishing arm 17 to be smoothly retracted into the storage and recovery groove 5 for storage and protection after the fire is extinguished.

[0071] When stacking fire-fighting rails 2: Place the fire-fighting rails 2 vertically, align the bottom splicing strip 3 of one fire-fighting rail 2 with the top splicing groove 4 of another fire-fighting rail 2, and then slowly lower it so that the splicing strip 3 is inserted into the splicing groove 4, thus achieving the initial stacking of the two rails. In the same way, stack the other fire-fighting rails 2 in sequence to form a vertical stacking structure. During the stacking process, ensure that each rail is placed stably and stacked neatly to avoid tilting or shaking. At the same time, some fixing devices such as ropes and clamps can be used to temporarily fix the stacked fire-fighting rails 2 to increase the stability of the stacking structure and facilitate handling and storage.

[0072] Primarily applicable to the storage and transportation of fire-fighting rails 2 during non-use periods, such as in fire equipment warehouses, stacking fire-fighting rails 2 can save significant space and improve warehouse storage efficiency. When transporting fire-fighting equipment to different locations, the stacked fire-fighting rails 2 occupy little space, facilitating vehicle loading and transportation, reducing transportation costs and difficulties, and significantly saving storage space. Whether in warehouse storage or during transportation, it effectively utilizes limited space resources, reducing the space requirements for site and transportation vehicles. This not only reduces storage and transportation costs but also improves logistics efficiency and facilitates the management and allocation of fire-fighting equipment. Simultaneously, the neatly stacked fire-fighting rails 2 facilitate rapid inventory and retrieval, enabling rapid deployment in emergencies, improving the timeliness and effectiveness of fire response, and providing strong support for ensuring the fire safety of distribution cabinets.

[0073] The limiting groove 7 and the limiting strip are key structural components for the flexible splicing and combination of fire-fighting rails 2. The limiting groove 7 is used to accommodate the limiting strip, so that multiple fire-fighting rails 2 can be tightly connected together to form enclosing rings of different shapes and sizes to adapt to the layout and installation position requirements of various power distribution cabinet bodies 1, thereby improving the versatility and adaptability of the fire-fighting device. The connection is made by means of clearance fit. The top surface of the fire-fighting rail 2 has splicing grooves 4 on both sides, and the bottom surface of the fire-fighting rail 2 has splicing strips 3 on both sides, and the splicing strips 3 are in clearance fit with the splicing grooves 4. One end of the fire-fighting rail 2 has a limiting block 6, and the other end of the fire-fighting rail 2 has a limiting groove 7, and the limiting groove 7 is in clearance fit with the limiting strip. Through the design of the splicing strips 3 and splicing grooves 4, the fire-fighting rails 2 can be easily assembled and spliced ​​to form enclosing rings of different shapes and sizes to adapt to the layout and installation position requirements of different power distribution cabinet bodies 1. During the splicing process, the gap fit between the splicing strip 3 and the splicing groove 4 ensures the tightness and stability of the connection. At the same time, the design of the limiting block 6 and the limiting groove 7 further ensures that the spliced ​​track structure is firm and reliable, and there will be no loosening or displacement. During the splicing process, the limiting strip of one fire track 2 is aligned with the limiting groove 7 of another fire track 2. Then, with appropriate external force or the assistance of installation tools, the limiting strip is smoothly inserted into the limiting groove 7, realizing the initial connection of the two tracks. In order to ensure the firmness and stability of the splicing, the cooperation of the limiting block 6 and the limiting groove 7 further restricts the relative position of the fire track 2 after splicing, avoiding loosening or misalignment, and ensuring the integrity and reliability of the entire splicing structure.

[0074] During the installation phase of the fire protection system, based on the actual shape, quantity, and distribution location of the main body 1 of the distribution cabinet, select an appropriate number and specifications of fire protection rails 2. First, place the first fire protection rail 2 in the predetermined position, and then sequentially insert the limiting strips of the other fire protection rails 2 into the limiting grooves 7 of the installed rails to complete the splicing operation, forming a ring of fire protection rails 2 surrounding the main body 1 of the distribution cabinet. During the splicing process, the operator needs to ensure that the limiting strips are fully inserted into the limiting grooves 7 and that the connection between each rail is tight and secure. After the splicing is completed, the entire spliced ​​structure is inspected and adjusted to ensure that it meets the installation requirements and the operating standards of the fire protection system. During the use of the fire protection system, the spliced ​​fire protection rail 2 structure can stably support and fix other components to jointly complete the fire extinguishing task. When the fire-fighting device needs to be disassembled or moved, the assembly process is reversed. The limiting strip is pulled out of the limiting groove 7, separating the fire-fighting rail 2 for easy handling and storage. This improves the flexibility and adaptability of the fire-fighting device, allowing for customized assembly combinations based on different distribution cabinet layouts. Whether it's a single distribution cabinet or a complex cluster of multiple distribution cabinets, a suitable fire protection structure can be quickly and accurately constructed, greatly expanding the application range of the fire-fighting device. Simultaneously, the design of the limiting groove 7 and the limiting strip facilitates the installation, disassembly, and handling of the fire-fighting device, reducing installation time and labor costs, and improving work efficiency. Furthermore, the robust and reliable assembly structure ensures the stability and reliability of the fire-fighting device during operation, preventing the fire-fighting effect from being affected by loose or displaced rails. This provides reliable protection for the fire safety of the distribution cabinet and reduces potential economic losses due to fire accidents, demonstrating its economic practicality in multiple aspects. Specific Implementation Example 3:

[0076] like Figures 1 to 19 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0077] A set of controllers is externally connected to the fire-fighting rail 2, and the controllers are electrically connected to the angle adjustment motor 16, the air pump 11, the electric shaft 24, the telescopic cylinder 23, the first electric control valve 20, and the second electric control valve 25. Temperature sensors and smoke detectors are installed on both the inner and outer walls of the main body of the distribution cabinet 1, and the temperature sensors and smoke detectors are located at multiple positions on the side of the main body of the distribution cabinet 1. At least one set of infrared cameras is installed on the outside of the installation position of the main body of the distribution cabinet 1, which is electrically connected to the angle adjustment motor 16 through the controller, and the temperature sensors and smoke detectors are electrically connected to the angle adjustment motor 16 through the controller.

[0078] The specific operation flow of the controller externally connected to fire protection rail 2 is as follows:

[0079] Sp1: Monitoring and Early Warning: Temperature sensors and smoke detectors on the inner and outer walls of the main body of the distribution cabinet 1 continuously monitor the internal environment of the distribution cabinet. When the temperature or smoke concentration reaches the preset alarm threshold, the temperature sensors and smoke detectors send signals to the controller.

[0080] Sp2: Start-up and preparation: After receiving the alarm signal, the controller starts the control system of the entire fire-fighting device and sends a command to the angle adjustment motor 16. The angle adjustment motor 16 drives the linear fire-fighting arm 17 to open from inside the storage and recovery tank 5, so that the linear fire-fighting arm 17 is in the initial position ready to extinguish the fire.

[0081] Sp3: Material Supply and Transfer: The controller controls the storage tank 14 to introduce fire extinguishing material into the U-shaped spray chamber 18 through the guide pipe 15, providing the material required for fire extinguishing to the linear fire extinguishing arm 17 and the rotating fire extinguishing arm 21. For the rotating fire extinguishing arm 21, when the second solenoid valve 25 at the end of the rotating fire extinguishing arm 21 coincides with the first solenoid valve 20, the controller controls the opening of these two solenoid valves, so that the U-shaped spray chamber 18 and the cavity inside the rotating fire extinguishing arm 21 are connected, realizing the transfer of material into the rotating fire extinguishing arm 21. After the material supply is completed, the controller controls both to close.

[0082] Sp4: Fire Extinguishing Operation: The spray nozzles 22 on the surfaces of the linear fire extinguishing arm 17 and the rotating fire extinguishing arm 21 begin to spray extinguishing materials for fire extinguishing. At the same time, the controller controls the telescopic cylinder 23 to push the rotating fire extinguishing arm 21 out from inside the linear fire extinguishing arm 17, and controls the electric shaft 24 to drive the rotating fire extinguishing arm 21 to rotate. Through the spray nozzles 22, the fire is extinguished in the high-altitude area, expanding the fire extinguishing coverage area. The controller adjusts the angle adjustment of the motor 16, the electric shaft 24 and the telescopic cylinder 23 in real time based on the information fed back by the temperature sensor, smoke alarm and infrared camera to ensure the fire extinguishing effect. For example, according to the location and range of the fire, the angle and position of the linear fire extinguishing arm 17 and the rotating fire extinguishing arm 21 are precisely adjusted so that the spray nozzles 22 can accurately aim at the fire source for efficient fire extinguishing.

[0083] SP5: Material Recovery: During the fire extinguishing process, the controller starts the air pump 11. The air pump 11 recovers the sprayed material under negative pressure through the air pipe 12 and the negative pressure hole 9 to prevent the material from accumulating around the main body of the power distribution cabinet 1, thereby reducing environmental pollution and the impact on the normal operation of the equipment.

[0084] Sp6: Fire Extinguishing End and Reset: When the temperature sensor and smoke alarm detect that the temperature and smoke concentration inside the main body of the power distribution cabinet 1 have returned to normal, that is, after the fire has disappeared, the controller controls the angle adjustment motor 16 to retract the linear fire extinguishing arm 17 into the storage and recovery tank 5, and at the same time controls the telescopic cylinder 23 to retract the rotating fire extinguishing arm 21 into the linear fire extinguishing arm 17, so that the entire fire protection device returns to its initial state and waits for the next fire monitoring and alarm.

[0085] As the core of the entire fire protection system, the controller is responsible for receiving and processing signals from various sensors such as temperature sensors, smoke detectors, and infrared cameras. According to the preset program and logic, it precisely controls and coordinates various components of the fire protection system, such as the angle adjustment motor 16, the air pump 11, the electric shaft 24, the telescopic cylinder 23, the first solenoid valve 20, and the second solenoid valve 25, to realize the automated operation and intelligent fire extinguishing of the fire protection system. This ensures that the system can respond quickly and effectively and take the best fire extinguishing measures when a fire occurs, protecting the safety of the main body of the distribution cabinet 1.

[0086] The controller typically employs technologies such as microprocessors or programmable logic controllers (PLCs), possessing functions including data acquisition, signal processing, logic judgment, and instruction output. It connects to various sensors via sensor interface circuits, receiving real-time data such as temperature, smoke concentration, and flame images, and converts these analog signals into digital signals for processing and analysis. Based on preset fire detection algorithms and thresholds, when the controller determines a fire has occurred, it immediately initiates the corresponding fire extinguishing program, sending control commands to each actuator in a predetermined logical sequence. For example, it sends an angle adjustment command to the angle adjustment motor 16, adjusting the linear fire extinguishing arm 17 to a suitable angle; sends a start signal to the air pump 11, establishing a negative pressure recovery environment; sends a rotation command to the electric shaft 24, driving the rotating fire extinguishing arm 21 to rotate; sends a telescopic command to the telescopic cylinder 23, controlling the extension and retraction of the rotating fire extinguishing arm 21; and sends opening and closing commands to the first and second solenoid valves 20 and 25, adjusting the flow rate and direction of the fire extinguishing materials, etc. During the firefighting process, the controller continuously monitors the data fed back by the sensors and the operating status of each component. It adjusts the control commands in real time according to the changes in the fire, optimizes the firefighting strategy, and ensures the maximum firefighting effect until the fire is extinguished. Then, it controls each component to return to standby state and records and stores the fire event for subsequent data analysis and equipment maintenance.

[0087] During the daily operation of the fire-fighting system, the controller remains in standby mode, continuously inspecting the sensors and monitoring environmental parameters around the main body of the distribution cabinet 1. Once a sensor detects an abnormal signal, such as a temperature rise exceeding a set threshold or smoke concentration reaching an alarm value, it immediately transmits the signal to the controller. Upon receiving the signal, the controller first verifies and analyzes it to confirm whether a fire has occurred. If a fire is detected, the controller quickly initiates the fire extinguishing procedure, sending control commands to each component sequentially according to a preset logical order, switching the fire-fighting system from standby mode to fire extinguishing operation mode. During fire extinguishing, the controller continuously adjusts the operating parameters and status of each component based on real-time data from the sensors. For example, it adjusts the spray flow rate of the extinguishing material according to the fire size, and adjusts the angle and rotation speed of the fire-extinguishing boom according to the fire source location, adapting to changes in the fire intensity and ensuring efficient fire extinguishing operations. Once the temperature sensor and smoke detector detect that the fire has been extinguished and environmental parameters have returned to normal, the controller stops all components, restoring the fire-fighting equipment to its initial standby state. It also records and stores data from the entire fire-fighting process, including the time of the fire, its duration, and the operational status of each component. This data is used for subsequent fire accident analysis and summarization, and provides a basis for performance evaluation and maintenance of the fire-fighting equipment. Through automated and intelligent control, the controller achieves rapid response and precise fire suppression, significantly improving fire-fighting efficiency. It enables rapid and effective fire-fighting measures in the early stages of a fire, extinguishing it in its initial stages, reducing damage to the main body of the distribution cabinet, and minimizing power outages and economic losses caused by the fire. Simultaneously, the controller's precise coordination and control of all components optimizes material consumption and equipment operation during the fire-fighting process, improving resource utilization and reducing fire-fighting costs. Furthermore, the controller's recording and storage functions facilitate in-depth analysis of fire accidents, providing data support for the improvement and upgrading of fire-fighting equipment, further enhancing its performance and reliability. In the long term, this provides strong protection for the safe and stable operation of the power system, resulting in significant economic and social benefits.

[0088] Temperature sensors and smoke detectors are front-end components of fire monitoring systems. They are responsible for real-time monitoring of temperature changes and smoke concentration inside and outside the main body of the distribution cabinet, timely detection of fire hazards and signs of fire, and providing accurate fire alarm signals to the controller so as to activate the fire-fighting system for fire suppression operations. They are key equipment for achieving early fire warning and rapid response.

[0089] Temperature sensors typically employ the principles of thermistors, thermocouples, or semiconductor temperature sensors. They utilize the characteristic that the resistance or electromotive force of a material changes with temperature to convert ambient temperature into an electrical signal, which is then output to the controller. When the temperature inside or around the main body of the distribution cabinet rises, the resistance or electromotive force of the temperature sensor changes accordingly. The controller detects this change and compares it with a preset temperature threshold to determine if there is a fire risk. Smoke detectors primarily operate based on optical principles such as light scattering, light reduction, or ionization. In optical smoke detectors, when smoke enters the detection chamber, it scatters or absorbs light, causing a change in the light intensity received by the photosensitive element, thereby generating a change in electrical signal that is transmitted to the controller. Ionization smoke detectors utilize radioactive elements to ionize the air. When smoke enters the ionization area, it changes the conductivity of the ions, triggering an alarm signal. When the smoke concentration reaches a certain level, exceeding the controller's preset alarm threshold, the smoke detector sends an alarm signal to the controller, indicating a potential fire.

[0090] During the daily operation of the fire protection system, temperature sensors and smoke detectors continuously monitor the internal and external environment of the main body of the distribution cabinet 1. At regular intervals, such as every few seconds or minutes, temperature and smoke concentration are sampled according to the specific equipment and application scenario, and the sampled data is transmitted to the controller in real time. The controller analyzes and processes this data in real time, comparing it with preset normal operating temperature ranges and smoke concentration thresholds. When the temperature or smoke concentration exceeds the corresponding threshold, the controller immediately determines that a fire has occurred and activates the fire extinguishing procedure of the fire protection system. During the fire, the temperature sensors and smoke detectors continue to monitor changes in environmental parameters, feeding back real-time data to the controller so that the controller can adjust the fire extinguishing strategy and control the operating status of various components according to the development of the fire. After the fire is extinguished, the temperature sensor and smoke detector continue to operate for a period of time to monitor whether environmental parameters have returned to normal. Once it is confirmed that the fire is completely extinguished and there are no signs of reignition, they return to normal monitoring status, awaiting the next fire alarm signal. This achieves early warning and real-time monitoring of fires in the main body of the distribution cabinet 1, enabling timely detection of fire signs in the early stages of a fire. This buys valuable time for rapid response of fire-fighting equipment and fire suppression operations, significantly improving the success rate of fire suppression and reducing the damage to the main body of the distribution cabinet 1 and its internal equipment. By promptly detecting and addressing fire hazards, power outages and equipment maintenance costs caused by fires are reduced, ensuring the stable operation of the power system, which has significant economic and safety value. At the same time, accurate fire monitoring also helps avoid unnecessary losses and chaos caused by false alarms or missed alarms, improving the reliability and practicality of fire-fighting equipment.

[0091] Infrared cameras, as auxiliary monitoring devices for fire suppression systems, can acquire real-time infrared images of the environment surrounding the main body of the distribution cabinet 1. This provides the controller with more intuitive and detailed information about the fire scene, including the location of the fire source, the size of the fire, and the direction of its spread. This assists the controller in more accurately formulating and adjusting fire suppression strategies, improving the effectiveness and targeting of fire suppression systems, and enhancing the ability to respond to complex fire scenarios. Infrared cameras utilize the infrared radiation emitted by objects themselves for imaging. Their core components include infrared detectors and optical lenses. The infrared detector converts the received infrared radiation signals into electrical signals, which are then processed and image generation algorithms convert into visualized infrared images. During a fire, the fire source and surrounding high-temperature areas emit strong infrared radiation. The infrared camera captures these radiation signals and converts them into clear infrared images, which are then transmitted to the controller via video transmission lines. The controller uses image processing technology to analyze the infrared images, extracting key information such as the location, shape, and temperature distribution of the fire source, thus providing a basis for fire suppression decisions.

[0092] When the fire-fighting equipment is in standby mode, the infrared camera continuously monitors the environment around the main body of the distribution cabinet 1, taking infrared images at regular intervals, such as every few seconds, and transmitting the image data to the controller. When a fire occurs, upon receiving an alarm signal from the temperature sensor or smoke detector, the controller immediately activates the infrared camera's rapid acquisition mode, increasing the image acquisition frequency to several frames per second, in order to obtain more timely and accurate information about the dynamic changes at the fire scene. The controller analyzes and processes the image data transmitted from the infrared camera in real time, adjusting the operating parameters of components such as the angle adjustment motor 16, electric shaft 24, and telescopic cylinder 23 according to the location of the fire source and the development of the fire, enabling the linear fire-fighting arm 17 and the rotating fire-fighting arm 21 to more accurately target the fire source for firefighting operations. During the firefighting process, the infrared camera continuously provides the controller with the latest images of the fire scene, and the controller continuously optimizes the firefighting strategy based on the image information until the fire is extinguished. After the fire was extinguished, the infrared camera resumed normal monitoring, continuing to monitor the environment around the main body of the distribution cabinet 1, awaiting the next fire alarm signal. This provided the fire-fighting equipment with more intuitive and comprehensive information about the fire scene, assisting the controller in achieving more precise fire-fighting control, improving fire-fighting efficiency and success rate, reducing damage to the main body of the distribution cabinet 1, and minimizing economic losses caused by the fire. Simultaneously, the use of the infrared camera enhanced the adaptability of the fire-fighting equipment to complex fire scenarios, enabling it to better handle situations such as concealed fire sources and large-scale fire spread, thus improving the overall safety of the fire protection system.

[0093] Through the close cooperation of various components and the precise control of the controller, the entire system control process enables timely detection, effective extinguishing, and automatic reset of fires in distribution cabinets. This improves the reliability and safety of outdoor electrical cabinet fire protection and allows for flexible response and handling based on different fire situations, ensuring the efficiency and stability of firefighting operations. Specific Implementation Example 4:

[0095] like Figures 1 to 19 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0096] The specific steps and applicable scenarios for assembling fire-fighting rail 2 into different shapes are further included below:

[0097] Piece together to form a pentagon:

[0098] Steps: First, prepare five identical fire-fighting rails 2. Place the first fire-fighting rail 2 in the predetermined position as a reference. Then, align the limiting strip of the second fire-fighting rail 2 with the limiting groove 7 of the first rail, completing the splicing on one side. Following the same method, splice the third, fourth, and fifth fire-fighting rails 2 sequentially to form a closed pentagonal structure. During the splicing process, ensure that the connections between each rail are tight and stable, and that the angles are accurate, to ensure the regularity and stability of the entire pentagon. The spliced ​​structure is as follows: Figure 17 As shown.

[0099] Applicable scenarios: Suitable for protecting pentagonal layout distribution cabinet groups, or in some limited spaces, the pentagonal splicing method can better fit the shape of the site, while providing comprehensive fire protection for the distribution cabinets. For example, in some small substations or specific industrial equipment layout areas, the distribution cabinets are distributed in a pentagonal shape. Using this splicing method can maximize the use of space and achieve effective fire coverage.

[0100] Beneficial effects: The pentagonal layout of the distribution cabinet provides customized fire protection, ensuring that fire extinguishing devices fully cover all sides of the cabinet, thus improving fire fighting effectiveness. Compared to other common shapes, the pentagonal design better fits the actual layout, reducing blind spots and the risk of fire spreading to unprotected areas. This better protects the distribution cabinet and its electrical equipment, reduces fire damage, and improves the efficiency of fire-fighting resource utilization, resulting in better economic benefits and safety.

[0101] Piecing them together to form a hexagon:

[0102] Steps: Take six fire-fighting rails 2. First, fix the first rail. Align the limiting strip of the second rail with the limiting groove 7 of the first rail and insert it. Continue in this manner, splicing the remaining rails until the sixth rail is connected end-to-end with the first rail, forming a complete hexagon. During the splicing process, carefully check the connection at each joint to ensure the hexagonal structure is stable, symmetrical, and that all sides are of consistent length. This ensures the reliability of the fire-fighting device during operation. The spliced ​​structure is as follows: Figure 18 As shown.

[0103] Applicable scenarios: Commonly used in hexagonal arrangement of distribution cabinet clusters. This layout is common in some large industrial plants or power distribution centers. Multiple distribution cabinets are combined in a hexagonal manner, and the fire-fighting rail 2 with hexagonal splicing can perfectly surround it, providing all-round fire protection for the entire distribution cabinet group, ensuring that a rapid response and fire-fighting operation can be carried out in the event of a fire, and protecting the safe operation of electrical equipment.

[0104] Beneficial effects: The hexagonal arrangement provides uniform and comprehensive protection for the distribution cabinet, effectively covering potential fire sources from all directions, and improving the applicability and extinguishing effect of the fire-fighting equipment. The close fit to the distribution cabinet layout reduces the possibility of fire spread due to inadequate protection, lowers the damage to the power system caused by fire, ensures production continuity, and reduces economic losses caused by power outages. Simultaneously, the hexagonal structure has good stability and symmetry, which is conducive to the uniform distribution and coordinated operation of components on the fire-fighting track 2, improving the overall performance and reliability of the fire-fighting equipment.

[0105] Piece together to form a circle:

[0106] Steps: For circular splicing, such as Figures 13 to 16 As shown, Figure 13 The completed shape is the arc-shaped fire-fighting track 2. Figure 14 The curved fire-fighting track 2 is in its open state after being assembled into a circle. Figure 15 and Figure 16 The image shows the stacked state of the arc-shaped fire-fighting rails 2. Since the end section of the fire-fighting rails 2 is an inverted convex structure and designed to be arc-shaped, the first arc-shaped fire-fighting rail 2 is first placed near the center position. Then, along the circumference, the splicing strips 3 of the subsequent arc-shaped fire-fighting rails 2 are spliced ​​with the splicing grooves 4 of the previous rail, gradually forming a circular structure. During the splicing process, attention should be paid to adjusting the curvature and splicing angle of each rail segment to ensure that the spliced ​​circle is smooth and continuous, without obvious gaps or misalignments. At the same time, the completed circular rails are inspected and fine-tuned to ensure that their center position is accurate and the radius meets the requirements, so as to meet the protection needs of the fire-fighting device for circular distribution cabinets or circular layout electrical equipment.

[0107] Applicable scenarios: Suitable for fire protection of circular distribution cabinets or electrical equipment arranged around circular objects, such as some large circular power transformers, special-shaped electrical control cabinets, etc. In these scenarios, the circular splicing fire rail 2 can closely fit the outline of the equipment, providing all-round, no-dead-angle fire protection, ensuring that in the event of a fire, the fire extinguishing device can quickly and effectively extinguish the fire, prevent the fire from causing serious damage to the equipment, and ensure the stable operation of the power system.

[0108] Beneficial Effects: The greatest advantage of circular splicing lies in its ability to perfectly fit circular objects, providing 360-degree seamless fire protection and greatly improving the extinguishing effect and coverage of fire-fighting devices. This tight-fitting design reduces the possibility of fire spreading to the interior of equipment or surrounding unprotected areas, effectively protecting the integrity and functionality of the equipment, reducing equipment maintenance and replacement costs caused by fire, and also reducing the impact of power outages caused by electrical equipment damage on production and daily life, resulting in significant economic and social benefits.

[0109] Assembled into a runway shape:

[0110] Steps: First, assemble two parallel straight fire-fighting rails 2, ensuring the distance between them meets design requirements and that they remain parallel and horizontal. Then, at both ends of the two straight rails, assemble curved fire-fighting rails 2, ensuring a tight connection between the curved and straight rails to form a closed racetrack-like structure. During the assembly process, ensure a smooth transition between the curved and straight rails, a firm and reliable connection at the joints, and accurate installation of all components. Simultaneously, inspect and adjust the entire racetrack-like structure to ensure its dimensional accuracy and stability meet the operational requirements of the fire-fighting equipment, enabling it to function properly in the event of a fire and provide effective fire protection for the distribution cabinet. The assembled structure is as follows: Figure 19 As shown.

[0111] Applicable Scenarios: Suitable for long, narrow distribution cabinet layouts with curved turns at both ends, commonly found in power distribution areas of large industrial production lines or narrow distribution rooms. In this layout, the racetrack-shaped fire-fighting track 2 can effectively protect the distribution cabinets along their arrangement direction, while also taking into account the curved sections at both ends, ensuring that the entire distribution cabinet area is within the protection range of the fire-fighting equipment. This allows for timely response and fire-fighting operations in the event of a fire, protecting the safety of electrical equipment.

[0112] Beneficial effects: The racetrack-shaped splicing method allows for customized protection based on specific power distribution cabinet layouts, making full use of space and improving the adaptability and practicality of fire protection equipment. By comprehensively covering long, narrow power distribution cabinet areas, it reduces the risk of fire spread, minimizes damage to the power system caused by fire, ensures the continuity of production processes, and avoids production stoppages and economic losses due to power outages. Furthermore, the racetrack-shaped structure is relatively simple and easy to assemble and install, reducing the installation cost and construction difficulty of fire protection equipment, while also facilitating subsequent maintenance and repair work, thus improving the overall cost-effectiveness of the fire protection system.

[0113] When assembling the entire structure, for the straight fire-fighting rail 2, all the contents of the above-mentioned specific implementation one can be directly adopted. For the arc-shaped fire-fighting rail 2, in actual use, the shape of the straight fire-fighting arm 17 is the same as that of the arc-shaped fire-fighting rail 2, which is an arc-shaped structure. Since the telescopic cylinder 23 and the rotating fire-fighting arm 21 with linear guidance inside the arc-shaped structure are prone to obstruction during extension and retraction, when setting the arc-shaped fire-fighting rail 2 and the arc-shaped straight fire-fighting arm 17, the rotating fire-fighting arm 21 and its corresponding connecting structure are not set inside the straight fire-fighting arm 17. At the same time, the first solenoid valve 20 set in the straight fire-fighting arm 17 is also removed, so that the storage box 14 can directly supply materials to the straight fire-fighting arm 17 through the guide pipe 15. Compared with the straight straight fire-fighting arm 17, the arc-shaped straight fire-fighting arm 17 has a larger and more concentrated fire-fighting range at the same height. The shape of the corresponding straight fire-fighting arm 17 is selected according to the actual use requirements.

[0114] Furthermore, since the included angle between adjacent fire rails 2 varies when they are spliced ​​into circular, pentagonal, hexagonal, or other structures other than quadrilaterals, the angles and positions of the limiting blocks 6 and limiting grooves 7 are selected according to the actual assembly shape during splicing. For example, for a circular structure, the limiting blocks 6 and limiting grooves 7 are set at both ends of the arc-shaped fire rail 2 for easy splicing. When splicing a regular hexagonal fire rail 2, the included angle between the installation positions of the limiting grooves 7 and the limiting blocks 6 is set to 60 degrees or 120 degrees to ensure the closure of the splicing between adjacent fire rails 2. Specific Implementation Example 5:

[0116] like Figures 1 to 19 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0117] To ensure installation stability, the fire-fighting rail 2 can be connected to the bottom surface via a fire hydrant after splicing, thus increasing stability.

[0118] Based on all the above, in the entire device structure, the air pump 11 and the storage tank 14 are both built into the fire rail 2. In actual use, due to volume limitations, the air pump 11 and the storage tank 14 can be externally mounted, that is, installed on one side of the fire rail 2, to ensure the stable operation of the entire device.

[0119] The material storage tank 14 increases the pressure of the material feed through the pressure valve at the end of the feed pipe 15 or an external pressure pump, so as to facilitate rapid spraying. At the same time, the material storage tank 14 stores existing publicly available fire extinguishing materials such as water or foam fire extinguishing agent for use.

[0120] In actual use, the entire device is controlled by a controller and powered by an external power supply to ensure its operation. The specific connection structure is set according to the needs of the actual use scenario and the publicly available technologies.

At least one set of infrared cameras is provided outside the installation position of the main body of the power distribution cabinet (1) and electrically connected to the angle adjustment motor (16) through the controller, and the temperature sensors and smoke alarms are electrically connected to the angle adjustment motor (16) through the controller.

6. The outdoor electrical cabinet fire-fighting device according to claim 5, characterized in that: The specific operation process of the controller externally connected to the fire-fighting rail (2) is as follows: Sp1: Monitoring and early warning: Temperature sensors and smoke alarms on the inner and outer walls of the main body of the power distribution cabinet (1) continuously monitor the internal environment of the power distribution cabinet. When the temperature or smoke concentration reaches the preset alarm threshold, the temperature sensor and smoke alarm send the signal to the controller. Sp2: Start-up and preparation: After receiving the alarm signal, the controller starts the control system of the entire fire-fighting device and sends a command to the angle adjustment motor (16). The angle adjustment motor (16) drives the linear fire-fighting arm (17) to open from inside the storage and recovery tank (5), so that the linear fire-fighting arm (17) is in the initial position ready to extinguish the fire. Sp3: Material supply and transmission: The controller controls the storage tank (14) to introduce the fire extinguishing material into the U-shaped spray chamber (18) through the guide pipe (15), providing the material required for fire extinguishing for the linear fire extinguishing arm (17) and the rotating fire extinguishing arm (21). For the rotating fire extinguishing arm (21), when the second solenoid valve (25) at the end of the rotating fire extinguishing arm (21) coincides with the first solenoid valve (20), the controller controls the opening of these two solenoid valves, so that the cavity inside the U-shaped spray chamber (18) and the rotating fire extinguishing arm (21) are connected, realizing the transmission of material into the rotating fire extinguishing arm (21). After the material supply is completed, the controller controls both to close. Sp4: Fire Extinguishing Operation: The spray holes (22) on the surfaces of the linear fire extinguishing arm (17) and the rotating fire extinguishing arm (21) begin to spray fire extinguishing materials for fire extinguishing. At the same time, the controller controls the telescopic cylinder (23) to push the rotating fire extinguishing arm (21) to extend from inside the linear fire extinguishing arm (17), and controls the electric shaft (24) to drive the rotating fire extinguishing arm (21) to rotate. The fire is extinguished in the high-altitude area through the spray holes (22), expanding the fire extinguishing coverage area. The controller adjusts the working status of the angle adjustment motor (16), electric shaft (24) and telescopic cylinder (23) in real time according to the information fed back by the temperature sensor, smoke alarm and infrared camera to ensure the fire extinguishing effect. According to the location and range of the fire, the controller precisely adjusts the angle and position of the linear fire extinguishing arm (17) and the rotating fire extinguishing arm (21) so that the spray holes (22) can accurately aim at the fire source for efficient fire extinguishing. Sp5: Material recovery: During the fire extinguishing process, the controller starts the air pump (11). The air pump (11) recovers the sprayed material under negative pressure through the air pipe (12) and negative pressure hole (9) to prevent the material from accumulating around the main body of the power distribution cabinet (1) and reduce the pollution to the environment and the impact on the normal operation of the equipment. Sp6: Fire Extinguishing End and Reset: When the temperature sensor and smoke alarm detect that the temperature and smoke concentration inside the main body of the distribution cabinet (1) have returned to normal, that is, after the fire has disappeared, the controller controls the angle adjustment motor (16) to retract the linear fire extinguishing arm (17) into the storage and recovery tank (5), and at the same time controls the telescopic cylinder (23) to retract the rotating fire extinguishing arm (21) into the linear fire extinguishing arm (17), so that the entire fire protection device is restored to its initial state and waits for the next fire monitoring and alarm.
