[0013] Preferably, a group of controllers are connected to the outside of the fire rail, and the controller is electrically connected to the angle adjustment motor, the vacuum pump, the electric shaft, the telescopic cylinder, the first electrically controlled valve, and the second electrically controlled valve. The inner and outer walls of the distribution cabinet body are provided with temperature sensors and smoke alarms, and the temperature sensors and smoke alarms are located at multiple positions on the side of the distribution cabinet body. At least one group of infrared cameras electrically connected to the angle adjustment motor through the controller is provided outside the installation position of the distribution cabinet body, and the temperature sensor and smoke alarm are electrically connected to the angle adjustment motor through the controller.

[0014] Preferably, the operation process of the controller connected externally to the firefighting track is as follows: Sp1: Monitoring and early warning: The temperature sensors on the inner and outer walls of the power distribution cabinet and the smoke alarm 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 a signal to the controller; Sp2: Start and prepare: 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.

[0015] Beneficial effects: The present invention provides an outdoor electric cabinet fire fighting device. It has the following beneficial effects: 1. The present invention has the characteristics of efficient fire extinguishing capability and high utilization optimization of space. The angle of the linear fire extinguishing support arm is adjusted by the angle adjustment motor, and the rotating fire extinguishing support arm is extended and rotated under the cooperation of the telescopic cylinder and the electric shaft, so that the spray hole can cover different positions and height ranges of the distribution cabinet body. Whether it is a fire source at a lower position inside the distribution cabinet or a fire spreading at a higher place, it can be effectively extinguished, greatly improving the comprehensiveness and accuracy of fire extinguishing, and effectively preventing the spread and spread of fire. The device relies on the temperature sensors and smoke alarms arranged inside and outside the distribution cabinet body for real-time monitoring. Once an abnormal situation is detected, the signal can be quickly transmitted to the controller. Then the entire fire-fighting device can be quickly started to achieve timely response and handling of fires. The linear fire-fighting arm can be stored in the storage recovery slot of the fire-fighting track when not in use, and the rotating fire-fighting arm can also be retracted into the linear fire-fighting arm. The entire fire-fighting device is in a retracted state when there is no fire, and will not occupy additional space around the distribution cabinet, ensuring the smooth installation and maintenance of the distribution cabinet. There is no need to reserve a special large-area operating space for the fire-fighting device, making the daily maintenance and maintenance of the distribution cabinet more convenient and efficient. At the same time, it also avoids obstacles to the passage of personnel and equipment operation around the distribution cabinet due to the presence of the fire-fighting device, thereby improving the space utilization and work convenience of outdoor electrical cabinets.

[0016] 2. The present invention uses an air pump in conjunction with an air guide pipe and a negative pressure hole to perform negative pressure recovery on the sprayed fire-extinguishing materials, so that these materials can be collected and can be used again for fire-fighting operations after proper treatment, thereby realizing the recycling of materials, reducing the consumption of fire-fighting materials, and reducing fire-fighting costs. At the same time, it also complies with the concepts of environmental protection and sustainable development. By recycling the fire-extinguishing materials, it avoids the random scattering and accumulation of materials around the distribution cabinet, and prevents the pollution of the surrounding soil, water bodies and other environments due to material residues, thereby protecting the ecological environment. Especially in outdoor use scenarios, it helps to maintain the cleanliness and stability of the surrounding natural environment, promote green development, save natural resources, and reduce the maintenance cost of the natural environment.

[0017] 3. The fire-fighting rails of the present invention can be stacked vertically when not in use, saving transportation space; when in use, according to the position and needs of the distribution cabinet body, they can be spliced ​​into polygonal shapes such as regular quadrilaterals, regular pentagons, regular hexagons, and can even be spliced ​​into circular or runway structures. This flexible splicing method enables the device to adapt to distribution cabinet bodies of different numbers and distribution positions. Whether it is a single distribution cabinet or a cluster composed of multiple distribution cabinets, it can provide appropriate fire protection, greatly improving the versatility and practicality of the device, and can meet various complex outdoor cabinet layout scenarios. Under the unified management of the controller, the various components of the entire fire-fighting device can be flexibly adjusted and work in coordination according to the actual situation at the fire scene. For example, according to the size of the fire, the direction of spread and the specific structure of the distribution cabinet, the controller can accurately control the action of components such as the angle adjustment motor, telescopic cylinder and electric shaft, optimize the fire-fighting strategy, ensure the best fire-fighting effect in different fire scenes, effectively respond to various complex and changeable fire situations, and provide reliable fire safety protection for the distribution cabinet.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 19 As shown, an outdoor electric cabinet fire fighting device comprises a distribution cabinet body 1 and a fire fighting track 2. A plurality of fire fighting tracks 2 of the same structure connected end to end are arranged on the outer side of the distribution cabinet body 1. The distribution cabinet body 1 is used to accommodate and protect electrical equipment. It is the core component of the entire power distribution system and is also the object of protection of the fire fighting device to prevent fire from damaging its internal electrical components and ensure the stability and safety of power supply. The fire fighting track 2 serves as the supporting structure and installation basis of the entire fire fighting device, and provides a stable installation position and running track for components such as the linear fire fighting arm 17, the angle adjustment motor 16, the rotating fire fighting arm 21, the material storage box 14, and the vacuum pump 11, ensuring that each component can accurately perform its function when working and cooperate to complete the fire fighting task. The internal negative pressure recovery chamber 8 and the storage recovery groove 5 and other structures are used for the recovery of fire fighting materials and the storage of fire fighting arms, respectively, realizing the material recycling and space optimization utilization of the device, and improving the environmental protection and practicality of the device.

[0022] A storage recovery groove 5 is provided on the top surface of the fire-fighting track 2, and a linear fire-fighting support arm 17 is provided at one end of the storage recovery groove 5. The storage recovery groove 5 is used to store the linear fire-fighting support arm 17 in a non-fire state, so that it can be neatly hidden inside the fire-fighting track 2 to avoid occupying additional space, thereby ensuring that the space around the power distribution cabinet body 1 is clean and unobstructed, facilitating the installation and maintenance of other equipment as well as the operation and passage of personnel. When a fire occurs, the necessary space and guidance are provided for the extension of the linear fire-fighting support arm 17, ensuring that the linear fire-fighting support arm 17 can quickly and accurately reach the predetermined fire-fighting position and smoothly carry out the fire-fighting operation. At the same time, it can also protect the linear fire-fighting support arm 17 from damage by the external environment when not in use, thereby extending its service life. An angle adjustment motor 16 is connected to the end of the arm 17, an adjustment slot 19 is provided near the center of the linear fire-fighting support arm 17, a rotating fire-fighting support arm 21 is slidably provided inside the adjustment slot 19, a telescopic cylinder 23 is bolted to the bottom surface of the adjusting slot 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-fighting support arm 21, and spray holes 22 are provided on the surfaces of the rotating fire-fighting support arm 21 and the linear fire-fighting support arm 17. The shape of the linear fire-fighting support arm 17 can be a straight line or an arc. The "straight line" in its name means that the fire-fighting material is sprayed along a straight line, that is, the fire-fighting state, and does not limit the shape of the fire-fighting support arm. The "rotation" in the rotating fire-fighting support arm 21 has the same meaning as its meaning, which is a rotating state. Fire extinguishing, the linear fire extinguishing arm 17 is one of the main executive parts of the fire extinguishing operation. The fire extinguishing material is sprayed to the fire source position of the distribution cabinet body 1 through the spraying holes 22 opened on its surface, and the fire is directly extinguished to prevent the spread and expansion of the fire. During the fire extinguishing process, the angle can be adjusted by the angle adjustment motor 16 to achieve accurate fire extinguishing of fire sources in different directions and heights, improve the effect and scope of fire extinguishing, and ensure that all parts of the distribution cabinet body 1 can be effectively protected by fire extinguishing. The fire extinguishing material in the storage box 14 is transported to the U-shaped spraying cavity through the guide pipe 15, and then evenly sprayed out from the spraying holes 22 on the surface of the linear fire extinguishing arm 17 to form a fire extinguishing jet to cover and extinguish the fire source. The angle adjustment of the arm 17 is achieved through the angle adjustment motor 16. The controller continuously adjusts the angle of the angle adjustment motor 16 and the material delivery amount of the storage box 14 to ensure the maximum fire extinguishing effect. If the fire is large and the fire extinguishing range needs to be expanded, the controller will start the telescopic cylinder 23 to push the rotating fire extinguishing support arm 21 out of the adjustment slide slot 19 of the linear fire extinguishing support arm 17, further improving the height and range of the fire extinguishing, and driving the linear fire extinguishing support arm 17 to rotate within a certain range, thereby adjusting the spraying direction of the spray hole 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 support arm 17 to stop spraying materials, and slowly retracts it into the storage recovery slot 5 to restore it to its initial state.

[0023] The adjusting slot 19 provides a sliding track and a supporting structure for the rotating fire-extinguishing support arm 21, so that it can perform telescopic movement inside the linear fire-extinguishing support arm 17, thereby changing the height and range of fire extinguishing, achieving effective fire fighting of fire sources at different heights, and improving the fire-fighting ability 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 support arm 21. When the telescopic cylinder 23 receives the command of the controller, its piston rod will perform telescopic movement, thereby pushing the rotating fire-extinguishing support arm 21 to slide up and down along the predetermined track in the adjusting slot 19, realizing the extension and retraction action of the rotating fire-extinguishing support arm 21, changing its position and height relative to the linear fire-extinguishing support arm 17, and then adjusting the range and height of fire extinguishing. In a non-fire state, the rotating fire-extinguishing support arm 21 is received in the adjusting slot 19 of the linear fire-extinguishing support arm 17 and is in a contracted state. At this time, the piston rod of the telescopic cylinder 23 is also in a retracted state. When a fire occurs and the fire is large, and it is necessary to expand the fire extinguishing range and height, the controller sends a start signal to the telescopic cylinder 23, and the piston rod of the telescopic cylinder 23 begins to extend, pushing the rotating fire extinguishing support arm 21 to slide upward along the adjustment slide 19, gradually extending from the linear fire extinguishing support arm 17, and stopping after reaching the predetermined fire extinguishing height. During the fire extinguishing process, according to the changes in the fire and the instructions of the controller, the telescopic cylinder 23 can adjust the telescopic length of the piston rod in real time, thereby changing the height of the rotating fire extinguishing support arm 21 to ensure effective fire fighting at different heights. After the fire is extinguished, the controller sends a contraction signal to the telescopic cylinder 23, and the piston rod of the telescopic cylinder 23 retracts, slowly pulling the rotating fire extinguishing support arm 21 back into the adjustment slide 19, restoring it to the initial contracted state, waiting to be activated again when the next fire occurs.

[0024] The rotating fire extinguishing arm 21 works in conjunction with the linear fire extinguishing arm 17 to form a multi-level, multi-angle fire extinguishing system that can adapt to distribution cabinet bodies 1 of different shapes and sizes and complex and changeable fire situations, thereby enhancing the versatility and practicality of the fire-fighting device.

[0025] The electric shaft 24 provides rotational power for the rotating fire-fighting support arm 21, so that it can rotate 360 ​​degrees in the horizontal direction, thereby evenly spreading the fire-fighting materials to a larger range, realizing all-round fire fighting of fire sources in different directions around the power distribution cabinet body 1, further expanding the fire-fighting coverage area of ​​the fire-fighting device, and improving the fire-fighting effect. The electric shaft 24 is usually composed of a motor, a reducer, a coupling, and an output shaft. When the controller sends a rotation instruction to the electric shaft 24, the motor starts to run, and the high-speed rotation of the motor is converted into a low-speed, high-torque output suitable for the rotation of the rotating fire-fighting support arm 21 through the reducer, and then the torque is transmitted to the output shaft through the coupling, driving the rotating fire-fighting support arm 21 to rotate around the output shaft. The rotation speed and direction of the electric shaft 24 can be accurately controlled by the controller according to the actual situation of the fire scene. By adjusting the speed and direction of the motor, the rotating fire-fighting support arm 21 can be rotated quickly and accurately, so that it can spray the fire-fighting materials to the location of the fire source that needs to be extinguished, forming an effective fire-fighting coverage area.

[0026] The design of the injection hole 22 usually takes into account the principle of fluid mechanics, and its aperture size, shape and distribution are optimized to ensure that the fire extinguishing material can form a stable and uniform jet during the injection process. When the fire extinguishing material enters the injection hole 22 under pressure, due to the throttling effect of the injection hole 22, the flow rate of the material increases, and the pressure energy is converted into kinetic energy, so that the fire extinguishing material is ejected at a high speed and rushes to the fire source, achieving the purpose of extinguishing the fire.

[0027] A U-shaped spraying cavity 18 is provided between the outer wall of the adjusting slide 19 and the inner wall of the linear fire extinguishing support arm 17, and the spraying hole 22 on the surface of the linear fire extinguishing support arm 17 penetrates the inside of the U-shaped spraying cavity 18, and the interior of the rotating fire extinguishing support arm 21 is a cavity structure, and a second mounting groove 13 is provided at one end of the fire-fighting track 2 close to the angle adjustment support arm, and a storage box 14 is provided inside the second mounting groove 13, and a guide pipe 15 is connected to the side of the storage box 14, and the top of the guide pipe 15 is connected to the inside of the U-shaped spraying cavity 18, and the storage box 14 is used to store the materials required for fire extinguishing, which is a fire-fighting device. The material reserve of the device ensures that when a fire occurs, it can provide continuous and sufficient fire-fighting materials to the linear fire-fighting support arm 17 and the rotating fire-fighting support arm 21, ensuring the smooth progress of the fire-fighting operation. It is an important material basis for the fire-fighting device to realize the fire-fighting function. The material guide pipe 15 serves as a channel for transporting the fire-fighting materials from the storage box 14 to the U-shaped spraying chamber, ensuring that the fire-fighting materials can be smoothly and stably transferred from the storage box 14 to the linear fire-fighting support arm 17 under pressure, providing a continuous material supply for the spraying hole 22, and ensuring the continuity and effectiveness of the fire-fighting operation.

[0028] A first electrically controlled valve 20 is embedded in the inner wall of the end of the U-shaped spray chamber 18 away from the angle adjustment motor 16, and second electrically controlled valves 25 are embedded on both sides of the end of the rotating fire extinguishing support arm 21 close to 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 support arm 17, and evenly distributes the fire extinguishing materials transported from the storage box 14 to the spray holes 22 on the surface of the linear fire extinguishing support arm 17, ensuring that the spray holes 22 can continuously and stably spray out fire extinguishing materials to effectively extinguish the fire source, and acts as a bridge connecting the storage box 14 and the spray holes 22, ensuring the smoothness and stability of the fire extinguishing materials during the transportation process, and also 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 equipment.

[0029] When the fire fighting device is in standby mode, the first electric control valve 20 is in a closed state, and there is no fire extinguishing material in the U-shaped spraying chamber. When a fire occurs and the controller starts the fire fighting device, the pressure valve set inside the guide pipe 15 is first opened, and the fire extinguishing material in the storage box 14 enters the U-shaped spraying chamber through the guide pipe 15 under pressure, and then is evenly distributed to each spraying hole 22, and starts to spray and extinguish the fire. During the fire extinguishing process, the controller adjusts the opening of the pressure valve in real time according to the size of the fire, the feedback information of the temperature sensor and the smoke alarm, and controls the flow and pressure of the fire extinguishing material entering the U-shaped spraying chamber to meet different fire extinguishing needs. When the fire is extinguished, the controller closes the pressure valve and stops the material delivery. The remaining material in the U-shaped spraying chamber can be recycled through the corresponding recovery device, such as connected to the negative pressure recovery chamber 8, and waits to be activated again when the next fire occurs.

[0030] A negative pressure recovery chamber 8 is provided inside the firefighting track 2, and negative pressure holes 9 are provided in a linear array on the bottom surface of the storage recovery groove 5, and the negative pressure holes 9 penetrate the inside of the negative pressure recovery chamber 8. A first installation groove 10 is provided on the side surface of the end of the firefighting track 2 away from the second installation groove 13, and an air pump 11 is provided inside the first installation groove 10. An air guide pipe 12 is connected to the surface of the air pump 11, and the end of the air guide pipe 12 penetrates the end of the negative pressure recovery chamber 8. The negative pressure recovery chamber 8 cooperates with the negative pressure holes 9 on the bottom surface of the storage recovery groove 5 and the air guide pipe 12 connected to the air pump 11. Under the action of the air pump 11, a negative pressure environment is generated, and the materials sprayed during the fire extinguishing process are sucked back to the negative pressure recovery chamber 8 for collection and subsequent treatment. , to achieve the recycling of materials, the negative pressure recovery chamber 8 is used to collect and recycle the fire extinguishing materials sprayed during the fire extinguishing process, to achieve the recycling of fire extinguishing materials, to reduce material waste and environmental pollution, and at the same time, it also helps to keep the environment around the power distribution cabinet body 1 clean and safe, and reduce the risk of secondary accidents caused by material residues. The negative pressure recovery chamber 8 is located inside the fire track 2, and cooperates with the negative pressure hole 9 on the bottom of the storage recovery slot 5 and the air guide pipe 12 connected to the vacuum pump 11. When the vacuum pump 11 is started, a negative pressure environment is formed in the negative pressure recovery chamber 8. The materials sprayed during the fire extinguishing process are sucked into the negative pressure recovery chamber 8 through the negative pressure hole 9 under the action of negative pressure for collection. The internal structure design of the negative pressure recovery chamber 8 is conducive to the precipitation and aggregation of materials. For example, guide plates, filters and other devices may be provided to enable the sucked materials to be distributed and deposited in an orderly manner in the cavity, which is convenient for subsequent recycling and processing.

[0031] The negative pressure hole 9 serves as the entrance for the fire extinguishing material to enter the negative pressure recovery chamber 8, and works in coordination with the negative pressure recovery chamber 8 and the vacuum pump 11. Under the action of the negative pressure generated by the vacuum pump 11, the fire extinguishing material scattered on the bottom surface and the surrounding of the storage recovery groove 5 during the fire extinguishing process is sucked into the negative pressure recovery chamber 8, thereby realizing the recovery of the material. The negative pressure hole 9 is a key component of the material recovery system.

[0032] The vacuum pump 11 is usually a centrifugal, piston or vacuum pump, and its working principle is based on the suction and compression mechanism of gas. When the vacuum pump 11 is started, the motor drives the impeller or piston and other components to run at high speed, so that a negative pressure area is formed at the air inlet of the pump, and the outside air is sucked into the pump under the action of the pressure difference, and then discharged through the exhaust port. In the material recovery system for fire-fighting equipment, the air inlet of the vacuum pump 11 is connected to the negative pressure recovery chamber 8 through the air duct 12, and the exhaust port leads to the outside atmosphere. As the pump continues to run, the air in the negative pressure recovery chamber 8 is continuously extracted, and the pressure gradually decreases, thereby forming a sufficient pressure difference inside and outside the cavity, prompting the fire-extinguishing material to enter the recovery chamber through the negative pressure hole 9. Specific embodiment 2: like Figures 1 to 19 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed: The entire firefighting track 2 is stacked in the vertical direction through the splicing strips 3 and the splicing grooves 4 during handling or transportation, which reduces the occupied space and facilitates handling. The cross-section of the end of the firefighting track 2 is an inverted convex structure. The width of the storage recovery groove 5 is the same as the width of the bottom end of the firefighting track 2, and the depth of the storage recovery groove 5 is twice the height of the bottom end of the firefighting track 2. The thickness of the linear fire-extinguishing support arm 17 is 1 / 2 of the depth of the storage recovery groove 5, and the width of the linear fire-extinguishing support arm 17 is the same as the width of the inner wall of the storage recovery groove 5. Such a size design enables the linear fire-extinguishing support arm 17 to be tightly embedded in the storage recovery groove 5, and During the extension and retraction process, it can move smoothly along the groove wall without jamming or offset. The splicing strips 3 are located on both sides of the bottom end of the fire rail 2, and the positions of the splicing strips 3 and the splicing grooves 4 correspond in the vertical direction. The two ends of the splicing groove 4 are blind grooves, and the two ends of the storage recovery groove 5 penetrate the two ends of the fire rail 2. The penetrating structure at the two ends of the storage recovery groove 5 ensures that the linear fire extinguishing support arm 17 is not hindered during extension and retraction, and can be fully extended to the predetermined fire extinguishing position. At the same time, it also facilitates the linear fire extinguishing support arm 17 to be smoothly retracted into the storage recovery groove 5 for storage and protection after the fire is extinguished.

[0034] When stacking the fire rails 2: place the fire rails 2 vertically, align the bottom splicing strip 3 of one fire rail 2 with the top splicing groove 4 of the other fire rail 2, and then slowly lower it to insert the splicing strip 3 into the splicing groove 4 to achieve the initial stacking of the two rails. In the same way, stack the other fire rails 2 in turn 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, clamps, etc. can be used to temporarily fix the stacked fire rails 2 to increase the stability of the stacking structure and facilitate transportation and storage.

[0035] It is mainly suitable for the storage and transportation of the fire rail 2 when it is not in use. For example, in a fire equipment warehouse, stacking the fire rail 2 can save a lot of space and improve the storage efficiency of the warehouse; when transporting the fire equipment to different places of use, the stacked fire rail 2 takes up little space, which is convenient for vehicle loading and transportation, reduces transportation costs and difficulties, and significantly saves storage space. Whether in warehouse storage or during transportation, it can effectively utilize limited space resources and reduce the space requirements for sites and transportation tools. This not only reduces storage costs and transportation costs, but also improves logistics efficiency and facilitates the management and deployment of fire equipment. At the same time, the neatly stacked fire rails 2 are easy to count and use quickly, and can be put into use quickly in an emergency, which improves the timeliness and effectiveness of fire response and provides strong support for ensuring the fire safety of the distribution cabinet.

[0036] The limiting groove 7 and the limiting strip are key structural components for the fire rail 2 to achieve flexible splicing and combination. The limiting groove 7 is used to accommodate the limiting strip, so that multiple fire rails 2 can be closely connected together to form encirclements of different shapes and sizes to adapt to the layout and installation position requirements of various distribution cabinet bodies 1, improve the versatility and adaptability of fire-fighting equipment, and are connected in a clearance fit manner. Splicing grooves 4 are provided on both sides of the top surface of the fire rail 2, and splicing strips 3 are provided on both sides of the bottom surface of the fire rail 2, and the splicing strips 3 are clearance-matched with the splicing grooves 4. A limiting block 6 is provided at one end of the fire rail 2, and a limiting groove 7 is provided at the other end of the fire rail 2, and the limiting groove 7 is clearance-matched with the limiting strip. Through the design of the splicing strips 3 and the splicing grooves 4, the fire rail 2 can be easily assembled and spliced ​​to form encirclements of different shapes and sizes to adapt to the layout and installation position requirements of different distribution cabinet bodies 1. During the splicing process, the clearance 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 limit block 6 and the limit groove 7 further ensures that the track structure after splicing is firm and reliable, and there will be no loosening or displacement. During the splicing process, the limit strip of one fire track 2 is aligned with the limit groove 7 of another fire track 2, and then the limit strip is smoothly inserted into the limit groove 7 through appropriate external force or with the assistance of installation tools to achieve the initial connection of the two tracks. In order to ensure the firmness and stability of the splicing, at the same time, the cooperation of the limit block 6 and the limit groove 7 further limits the relative position of the fire track 2 after splicing, avoids loosening or dislocation, and ensures the integrity and reliability of the entire splicing structure.

[0037] During the installation phase of the fire-fighting device, select the appropriate number and specifications of fire-fighting rails 2 according to the actual shape, quantity and distribution position of the power distribution cabinet body 1. First, place the first fire-fighting rail 2 in the predetermined position, and then insert the limit bars of other fire-fighting rails 2 into the limit grooves 7 of the installed rails in turn to complete the splicing operation, forming an encirclement of the fire-fighting rails 2 around the power distribution cabinet body 1. During the splicing process, the operator needs to ensure that the limit bars are fully inserted into the limit grooves 7, and that the connections between the rails are tight and firm. After the splicing is completed, check and adjust the entire splicing structure to ensure that it meets the installation requirements and the operating standards of the fire-fighting device. During the use of the fire-fighting device, the spliced ​​fire-fighting rail 2 structure can stably support and fix other components to jointly complete the fire-fighting task. When the fire-fighting device needs to be disassembled or moved, the splicing process is reversed, and the limit bar is pulled out from the limit groove 7, so that the fire-fighting track 2 can be separated, which is convenient for transportation and storage, and improves the flexibility and adaptability of the fire-fighting device. It can be customized according to the layout of different distribution cabinets. Whether it is a single distribution cabinet or a complex cluster composed of multiple distribution cabinets, a suitable fire protection structure can be quickly and accurately built, which greatly expands the application scope of the fire-fighting device. At the same time, the design of the limit groove 7 and the limit bar facilitates the installation, disassembly and transportation of the fire-fighting device, reduces the installation time and labor costs, and improves work efficiency. In addition, the firm and reliable splicing structure ensures the stability and reliability of the fire-fighting device during operation, avoids the fire-fighting effect affected by the loosening or displacement of the track, provides reliable protection for the fire safety of the distribution cabinet, reduces the economic losses that may be caused by fire accidents, and reflects its economic practicality from many aspects. Specific embodiment three: like Figures 1 to 19 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed: A group of controllers are connected to the outside of the fire track 2, and the controller is electrically connected to the angle adjustment motor 16, the vacuum pump 11, the electric shaft 24, the telescopic cylinder 23, the first electrically controlled valve 20, and the second electrically controlled valve 25. Temperature sensors and smoke alarms are provided on the inner and outer walls of the distribution cabinet body 1, and the temperature sensors and smoke alarms are located at multiple positions on the side of the distribution cabinet body 1. At least one group of infrared cameras electrically connected to the angle adjustment motor 16 through the controller is provided outside the installation position of the distribution cabinet body 1, and the temperature sensor and smoke alarm are electrically connected to the angle adjustment motor 16 through the controller.

[0039] The operation process of the controller connected externally to Fire Track 2 is as follows: Sp1: Monitoring and early warning: The temperature sensors on the inner and outer walls of the power distribution cabinet body 1 and the smoke alarm 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 the smoke alarm send a signal to the controller; Sp2: Start and prepare: 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 support arm 17 to open from the inside of the storage recovery slot 5, so that the linear fire-fighting support arm 17 is in the initial position ready for fire extinguishing; Sp3: Material supply and transmission: The controller controls the material storage box 14 to introduce the fire extinguishing material into the U-shaped spraying cavity 18 through the material guide pipe 15, and provides the linear fire extinguishing support arm 17 and the rotating fire extinguishing support arm 21 with the materials required for fire extinguishing. For the rotating fire extinguishing support arm 21, when the second electric control valve 25 at the end of the rotating fire extinguishing support arm 21 coincides with the first electric control valve 20, the controller controls the opening of the two electric control valves to make the U-shaped spraying cavity 18 and the cavity inside the rotating fire extinguishing support arm 21 connected, so as to realize the transmission of materials to the inside of the rotating fire extinguishing support arm 21. After the material supply is completed, the controller controls the two to close; Sp4: Fire extinguishing operation: The spray holes 22 on the surface of the linear fire extinguishing support arm 17 and the rotating fire extinguishing support arm 21 begin to spray fire extinguishing materials to extinguish the fire. At the same time, the controller controls the telescopic cylinder 23 to push the rotating fire extinguishing support arm 21 out from the inside of the linear fire extinguishing support arm 17, and controls the electric shaft 24 to drive the rotating fire extinguishing support arm 21 to rotate, and extinguish the high altitude range through the spray holes 22 to expand the fire extinguishing coverage area. The controller adjusts the working state of the angle adjustment motor 16, the electric shaft 24 and the telescopic cylinder 23 in real time according to the information fed back by the temperature sensor, the smoke alarm and the 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 support arm 17 and the rotating fire extinguishing support arm 21 are accurately adjusted 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 vacuum pump 11, and the vacuum pump 11 recovers the ejected materials under negative pressure through the air guide pipe 12 and the negative pressure hole 9, so as to prevent the materials from accumulating around the power distribution cabinet body 1, thereby reducing the pollution to the environment and the impact on the normal operation of the equipment; Sp6: End of fire extinguishing and reset: When the temperature sensor and smoke alarm detect that the temperature and smoke concentration inside the distribution cabinet body 1 have returned to normal, that is, the fire has disappeared, the controller controls the angle adjustment motor 16 to retract the linear fire extinguishing arm 17 into the storage recovery slot 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-fighting device returns to its initial state and waits for the next fire monitoring and alarm.

[0040] As the control core of the entire fire-fighting device, the controller is responsible for receiving and processing signals from various sensors such as temperature sensors, smoke alarms, infrared cameras, etc., and according to preset programs and logics, it accurately controls and coordinates various components of the fire-fighting device such as the angle adjustment motor 16, the vacuum pump 11, the electric shaft 24, the telescopic cylinder 23, the first electric-controlled valve 20, the second electric-controlled valve 25, etc., to achieve automated operation and intelligent fire extinguishing of the fire-fighting device, ensure rapid and effective response and take the best fire-fighting measures when a fire occurs, and protect the safety of the distribution cabinet body 1.

[0041] The controller usually adopts technologies such as microprocessor or programmable logic controller PLC, and has functions such as data acquisition, signal processing, logic judgment and command output. It is connected to various sensors through sensor interface circuits, receives data information such as temperature, smoke concentration, flame image, etc. collected by the sensors in real time, and converts these analog signals into digital signals for processing and analysis. According to the preset fire judgment algorithm and threshold, when the controller judges that a fire has occurred, it immediately starts the corresponding fire extinguishing program and sends control instructions to each execution component in a predetermined logical order. For example, an angle adjustment instruction is sent to the angle adjustment motor 16 to adjust the linear fire extinguishing arm 17 to a suitable angle; a start signal is sent to the vacuum pump 11 to establish a negative pressure recovery environment; a rotation instruction is sent to the electric shaft 24 to drive the rotating fire extinguishing arm 21 to rotate; a telescopic instruction is sent to the telescopic cylinder 23 to control the extension and retraction of the rotating fire extinguishing arm 21; an opening and closing instruction is sent to the first electric control valve 20 and the second electric control valve 25 to adjust the flow rate and flow direction of the fire extinguishing material, etc. During the fire-fighting process, the controller continuously monitors the data fed back by the sensors and the operating status of each component, adjusts the control instructions in real time according to the changes in the fire intensity, optimizes the fire-fighting strategy, and ensures the maximum fire-fighting effect until the fire is extinguished. It then controls each component to return to standby mode and records and stores the fire event for subsequent data analysis and equipment maintenance.

[0042] In the daily operation of the fire-fighting device, the controller is in standby mode, continuously inspecting the sensors and monitoring the environmental parameters around the power distribution cabinet body 1. Once the sensor detects an abnormal signal such as a temperature rise exceeding the set threshold or the smoke concentration reaching the alarm value, the signal is immediately transmitted to the controller. After receiving the signal, the controller first verifies and analyzes the signal to confirm whether a fire has occurred. If it is determined that a fire has occurred, the controller quickly starts the fire-fighting program and sends control instructions to each component in sequence according to the preset logical sequence, so that the fire-fighting device switches from the standby state to the fire-fighting working state. During the fire-fighting process, the controller continuously adjusts the working parameters and operating status of each component based on the real-time data fed back by the sensor, such as adjusting the injection flow of the fire-fighting material according to the size of the fire, adjusting the angle and rotation speed of the fire-fighting arm according to the location of the fire source, etc., to adapt to changes in the fire and ensure the efficient implementation of the fire-fighting operation. When the temperature sensor and smoke alarm detect that the fire has been extinguished and the environmental parameters have returned to normal, the controller controls each component to stop working, restores the fire-fighting device to the initial standby state, and records and stores the data of the entire fire-fighting process, including the time of fire occurrence, duration, working status of each component, etc., so as to analyze and summarize the fire accident later, and also provide a basis for the performance evaluation and maintenance of the fire-fighting device. Through automated and intelligent control, the controller realizes the rapid response and precise fire-fighting of the fire-fighting device, greatly improves the fire-fighting efficiency, can quickly take effective fire-fighting measures at the early stage of the fire, put out the fire in the bud, reduces the damage caused by the fire to the distribution cabinet body 1, and reduces the power outage accidents and economic losses caused by the fire. At the same time, the precise coordination and control of the controller to each component optimizes the material consumption and equipment operation in the fire-fighting process, improves the resource utilization rate, and reduces the fire-fighting cost. In addition, the recording and storage function of the controller helps to conduct in-depth analysis of fire accidents, provide data support for the improvement and upgrading of fire-fighting devices, and further improve their performance and reliability. In the long run, it provides a strong guarantee for the safe and stable operation of the power system, with significant economic and social benefits.

[0043] The temperature sensor and smoke alarm are the front-end components of fire monitoring of the fire-fighting device. They are responsible for real-time monitoring of the temperature changes and smoke concentration inside and outside the distribution cabinet body 1, timely discovering fire hazards and signs of fire, and providing accurate fire alarm signals to the controller to start the fire-fighting device for fire extinguishing operations. They are key equipment for achieving early warning and rapid response to fires.

[0044] The temperature sensor usually adopts the principle of thermistor, thermocouple or semiconductor temperature sensor, and uses the characteristics of the resistance value or electromotive force of the material changing with temperature to convert the ambient temperature into an electrical signal and output it to the controller. When the temperature inside the power distribution cabinet body 1 or the surrounding environment rises, the resistance value or electromotive force of the temperature sensor changes accordingly. The controller detects the change signal and compares it with the preset temperature threshold to determine whether there is a fire risk. The smoke alarm mainly works based on optical principles such as scattered light, dimming or ion smoke sensing principles. In an optical smoke alarm, when smoke enters the detection chamber, it will cause light to be scattered or absorbed, causing the light intensity received by the photosensitive element to change, thereby generating an electrical signal change and transmitting it to the controller; the ion smoke alarm uses radioactive elements to ionize the air. When the smoke enters the ionized area, it will change the conductivity of the ions, thereby triggering an alarm signal. When the smoke concentration reaches a certain level and exceeds the alarm threshold preset by the controller, the smoke alarm will send an alarm signal to the controller to indicate that a fire may occur.

[0045] In the daily operation of the fire-fighting device, the temperature sensor and the smoke alarm continuously monitor the internal and external environment of the power distribution cabinet body 1. At certain time intervals, such as a few seconds or minutes, the temperature and smoke concentration are sampled according to the specific equipment and application scenario settings, and the sampled data are transmitted to the controller in real time. The controller analyzes and processes these data in real time and compares them with the preset normal working temperature range and smoke concentration threshold. When the temperature or smoke concentration exceeds the corresponding threshold, the controller immediately determines that a fire has occurred and starts the fire-fighting device's fire-fighting program. During the fire, the temperature sensor and the smoke alarm continue to monitor the changes in environmental parameters and feed back real-time data to the controller so that the controller can adjust the fire-fighting strategy and control the operating status of each component according to the development of the fire. After the fire is extinguished, the temperature sensor and smoke alarm continue to work for a period of time to monitor whether the environmental parameters have returned to normal. After confirming that the fire is completely extinguished and there is no sign of re-ignition, it returns to the normal monitoring state and waits for the next fire alarm signal to be triggered, realizing early warning and real-time monitoring of the fire in the distribution cabinet body 1, and being able to promptly detect signs of fire in the early stages of the fire, buying precious time for the rapid response and fire-fighting operations of the fire-fighting equipment, greatly improving the success rate of fire fighting, and reducing the degree of damage to the distribution cabinet body 1 and its internal equipment caused by the fire. By timely discovering and handling fire hazards, power outages and equipment maintenance costs caused by fire are reduced, and the stable operation of the power system is guaranteed, which has important economic significance and safety value. At the same time, accurate fire monitoring also helps to avoid unnecessary losses and confusion caused by false alarms or missed alarms, and improves the reliability and practicality of fire-fighting equipment.

[0046] As an auxiliary monitoring device of the fire-fighting device, the infrared camera can obtain infrared image information of the surrounding environment of the power distribution cabinet body 1 in real time, provide the controller with more intuitive and detailed fire scene conditions, including the location of the fire source, the size of the fire, the direction of spread, etc., assist the controller to formulate and adjust the fire-fighting strategy more accurately, improve the fire-fighting effect and pertinence of the fire-fighting device, and enhance the ability to respond to complex fire scenes. The infrared camera uses the infrared radiation emitted by the object itself for imaging, and its core components include infrared detectors and optical lenses. The infrared detector can convert the received infrared radiation signal into an electrical signal, and then convert the electrical signal into a visual infrared image through signal processing and image generation algorithms. When a fire occurs, the fire source and the surrounding high-temperature area will emit strong infrared radiation. The infrared camera can capture these radiation signals and convert them into clear infrared images, and transmit the image data to the controller through the video transmission line. The controller uses image processing technology to analyze the infrared image and extract key information such as the location, shape, and temperature distribution of the fire source, thereby providing a basis for fire-fighting decisions.

[0047] When the fire fighting device is in standby mode, the infrared camera continuously monitors the environment around the power distribution cabinet body 1, takes an infrared image every certain time interval, such as a few seconds, and transmits the image data to the controller. When a fire occurs, the controller immediately starts the fast acquisition mode of the infrared camera after receiving the alarm signal from the temperature sensor or smoke alarm, and increases the image acquisition frequency, such as collecting several frames of images per second, so as to obtain the dynamic change information of the fire scene more timely and accurately. The controller analyzes and processes the image data transmitted by the infrared camera in real time, and adjusts the working parameters of the angle adjustment motor 16, the electric shaft 24, the telescopic cylinder 23 and other components according to the location of the fire source and the development of the fire, so that the linear fire extinguishing support arm 17 and the rotating fire extinguishing support arm 21 can be more accurately aimed at the fire source for fire extinguishing operations. During the fire extinguishing process, the infrared camera continuously provides the latest fire scene images to the controller, and the controller continuously optimizes the fire extinguishing strategy according to the image information until the fire is extinguished. After the fire is extinguished, the infrared camera returns to the normal monitoring state and continues to monitor the environment around the power distribution cabinet body 1, waiting for the next fire alarm signal to be triggered, providing the fire-fighting device with more intuitive and comprehensive fire scene information, assisting the controller to achieve more accurate fire-fighting control, improving the efficiency and success rate of fire-fighting, reducing the damage caused by the fire to the power distribution cabinet body 1, and reducing the economic losses caused by the fire. At the same time, the use of infrared cameras enhances the adaptability of fire-fighting devices to complex fire scenes, and can better deal with situations such as hidden fire sources and large-scale fire spread, thereby improving the safety of the entire fire-fighting system.

[0048] The entire system control procedure, through the close coordination of various components and precise regulation of the controller, realizes the timely discovery of distribution cabinet fires, effective firefighting and automatic resetting of the device, improves the reliability and safety of outdoor cabinet fire protection, and can flexibly respond and handle according to different fire situations, ensuring the efficiency and stability of fire-fighting operations. Specific embodiment four: like Figures 1 to 19 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed: The specific steps and scenarios applicable to the fire track 2 when it is spliced ​​into different shapes further include the following: Stitching into a pentagon: Steps: First, prepare five identical firefighting rails 2, place the first firefighting rail 2 at the predetermined position as a reference, then align the limit strip of the second firefighting rail 2 with the limit groove 7 of the first rail in turn to complete the splicing of one side, and in the same way, splice the third, fourth and fifth firefighting rails 2 in turn to form a closed pentagonal structure. Pay attention to ensuring that the connection between the rails is tight and stable during the splicing process, and the angle is accurate to ensure the regularity and stability of the entire pentagon. The spliced ​​structure is as follows: Fig.17 shown.

[0050] Applicable scenarios: Suitable for protecting pentagonal distribution cabinet groups, or in some limited spaces, the pentagonal splicing method can better fit the shape of the site and provide 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. This splicing method can maximize the use of space and achieve effective fire protection coverage.

[0051] Beneficial effects: It can closely surround the pentagonal layout of the distribution cabinet, provide customized fire protection, ensure that the fire extinguishing device can fully cover all sides of the distribution cabinet, and improve the fire fighting effect. Compared with other general-shaped protection, the pentagonal splicing is more in line with the actual layout, reduces the blind spots of protection, and reduces the risk of fire spreading to unprotected areas, thereby better protecting the distribution cabinet and the electrical equipment therein, reducing the losses caused by fire, and improving the utilization efficiency of fire fighting resources, with better economic benefits and safety.

[0052] Stitching into hexagons: Steps: Take six firefighting rails 2, fix the first rail first, align the limit strip of the second rail with the limit slot 7 of the first rail and insert it, and so on, splice the remaining rails in sequence until the sixth rail is connected to the first rail end to end to form a complete hexagon. During the splicing process, carefully check the connection of each splicing point to ensure that the hexagonal structure is stable and symmetrical, and the length of each side is consistent, so as to ensure the reliability of the firefighting device during operation. The structure after splicing is as follows: Fig.18 shown.

[0053] Applicable scenarios: It is commonly used in hexagonally arranged distribution cabinet clusters. This layout is more common in some large industrial plants or power distribution centers. Multiple distribution cabinets are combined in a hexagonal manner. The hexagonal fire track 2 can perfectly surround them, providing all-round fire protection for the entire distribution cabinet group, ensuring rapid response and fire extinguishing operations in the event of a fire, and protecting the safe operation of power equipment.

[0054] Beneficial effects: Hexagonal splicing can provide uniform and comprehensive protection for the distribution cabinet, effectively cover potential fire sources in all directions, and improve the applicability and fire extinguishing effect of the fire-fighting device. By closely fitting the layout of the distribution cabinet, the possibility of fire spreading due to improper protection is reduced, the degree of damage to the power system caused by fire is reduced, the continuity of production is guaranteed, and the economic losses caused by power outages are reduced. At the same time, the hexagonal structure has good stability and symmetry, which is conducive to the uniform distribution and coordinated work of various components on the fire track 2, and improves the overall performance and reliability of the fire-fighting device.

[0055] Stitching into a circle: Steps: For circular stitching, such as Figures 13 to 16 As shown, Fig.13 The arc-shaped firefighting track 2 is spliced ​​together to form a complete shape. Fig.14 The arc-shaped firefighting track 2 is spliced ​​into a circle and then opened. Fig.15 and Fig.16 The arc-shaped fire rail 2 is in a stacked state. Since the cross-section of the end of the fire rail 2 is an inverted convex structure and is designed to be arc-shaped, the first arc-shaped fire rail 2 is first placed near the center of the circle, and then the splicing strips 3 of the subsequent arc-shaped fire rails 2 are spliced ​​with the splicing grooves 4 of the previous rail in sequence along the circumferential direction to gradually form a circular structure. During the splicing process, attention should be paid to adjusting the curvature and splicing angle of each section of the rail to ensure that the spliced ​​circle is smooth and continuous without obvious gaps or misalignments. At the same time, the spliced ​​circular rail is inspected and fine-tuned as a whole to ensure that its center of the circle is accurate and the radius meets the requirements to meet the protection needs of the fire protection device for the circular distribution cabinet or circular electrical equipment.

[0056] 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 spliced ​​fire rail 2 can fit the contour of the equipment tightly, providing all-round and no-dead-angle fire protection, ensuring that when a fire occurs, the fire extinguishing device can quickly and effectively extinguish the equipment, prevent the fire from causing serious damage to the equipment, and ensure the stable operation of the power system.

[0057] Beneficial effects: The biggest advantage of circular splicing is that it can achieve perfect fit for circular objects, provide 360-degree seamless fire protection, and greatly improve the fire extinguishing effect and coverage of fire-fighting equipment. This tightly fitting design reduces the possibility of fire spreading to the inside of the equipment or the surrounding unprotected areas, effectively protects the integrity and functionality of the equipment, reduces the equipment maintenance and replacement costs caused by fire, and also reduces the impact of power outages caused by damage to power equipment on production and life, with significant economic and social benefits.

[0058] Splicing into a runway shape: Steps: First, splice two parallel straight fire rails 2, ensuring that the distance between them meets the design requirements and remains parallel and horizontal. Then, splice the curved fire rails 2 at both ends of the two straight rails, so that the joints of the curved rails and the straight rails are tightly connected to form a closed runway-type structure. During the splicing process, attention should be paid to ensure that the transition between the curved rails and the straight rails is smooth, the connection at the joints is firm and reliable, and the installation positions of each component are accurate. At the same time, the entire runway-type structure is inspected and debugged to ensure that its dimensional accuracy and stability meet the operating requirements of the fire-fighting device, so that it can function normally in the event of a fire and provide effective fire protection for the distribution cabinet. The spliced ​​structure is as follows: Fig.19 shown.

[0059] Applicable scenarios: Suitable for distribution cabinets with long strips and curved turns at both ends, which are commonly seen in the power distribution area of ​​some large industrial production lines or narrow distribution rooms. In this layout, the runway-type spliced ​​firefighting track 2 can effectively protect along the arrangement direction of the distribution cabinets, while taking into account the curved parts at both ends, ensuring that the entire distribution cabinet area is within the protection range of the fire-fighting device, and can respond and implement fire-fighting operations in a timely manner when a fire occurs, protecting the safety of power equipment.

[0060] Beneficial effects: The runway-type splicing method can provide customized protection according to the specific layout of the distribution cabinet, make full use of the space, improve the adaptability and practicality of the fire-fighting device, and reduce the risk of fire spread and damage to the power system caused by fire by fully covering the long strip distribution cabinet area, ensuring the continuity of the production process and avoiding production stagnation and economic losses caused by power outages. In addition, the runway-type structure is relatively simple and easy to splice and install, which reduces the installation cost and construction difficulty of the fire-fighting device, and also facilitates subsequent maintenance and overhaul work, improving the overall cost performance of the fire-fighting system.

[0061] When the above-mentioned entire structure is actually spliced, all the contents of the above-mentioned specific implementation one can be directly adopted for the linear fire rail 2. For the curved fire rail 2, in actual use, the shape of the linear fire extinguishing support arm 17 is the same as the shape of the curved fire rail 2, which is an arc-shaped structure. Since the linearly guided telescopic cylinder 23 and the rotating fire extinguishing support arm 21 are arranged inside the curved structure, it is easy to be blocked during telescoping. Therefore, when the curved fire rail 2 and the curved linear fire extinguishing support arm 17 are arranged, the rotating fire extinguishing support arm 21 and its corresponding connecting structure are not arranged inside the linear fire extinguishing support arm 17. At the same time, the first electric control valve 20 arranged on the linear fire extinguishing support arm 17 is also removed, so that the material storage box 14 can directly feed the linear fire extinguishing support arm 17 through the material guide pipe 15. Compared with the linear linear fire extinguishing support arm 17, the curved linear fire extinguishing support arm 17 has a larger and more concentrated fire extinguishing range at the same height due to the curved design. The shape of the corresponding linear fire extinguishing support arm 17 is selected according to actual use requirements.

[0062] Furthermore, since the angles between adjacent fire rails 2 are different when the entire fire rail 2 is spliced ​​into other structures other than quadrilaterals such as circles, pentagons, hexagons, etc., the angles of the limit blocks 6 and the limit grooves 7 are selected according to the actual assembly shape during splicing. For example, for a structure spliced ​​into a circle, the limit blocks 6 and the limit grooves 7 are arranged at the two ends of the arc-shaped fire rail 2 for ease of splicing. When splicing a regular hexagonal fire rail 2, the installation position angle of the limit groove 7 and the limit block 6 is set to 60 degrees or 120 degrees to ensure the closure of the splicing between adjacent fire rails 2. Specific embodiment five: like Figures 1 to 19 As shown, according to the contents in the above specific embodiments, the following contents are further disclosed: To ensure the stability of the installation, the fire rail 2 can be connected to the bottom surface through a bolt after splicing to increase stability.

[0064] According to all the above contents, in the structure of the entire device, the vacuum pump 11 and the storage box 14 both adopt the built-in structure of the fire track 2. In actual use, the vacuum pump 11 and the storage box 14 can adopt an external structure due to volume limitations, that is, they can be installed on one side of the fire track 2 to ensure the stable operation of the entire device.

[0065] The material storage box 14 increases the pressure of the material feed through a pressure valve or an external pressure pump at the end of the material guide pipe 15 to facilitate rapid spraying. At the same time, the material storage box 14 stores existing public fire extinguishing materials such as water or foam fire extinguishing agent for use.

[0066] The entire device is controlled as a whole by a controller during actual use, and is powered by an external power supply device to ensure the operation of the entire device. The specific connection structure is set according to the needs of the actual use scenario and the publicly available prior art.

At least one group of infrared cameras electrically connected to the angle adjustment motor (16) through the controller is externally provided at the installation position of the power distribution cabinet body (1), and the temperature sensor and the smoke alarm are electrically connected to the angle adjustment motor (16) through the controller.

9. The outdoor electric cabinet fire fighting device according to claim 8, characterized in that: The operation process of the controller externally connected to the firefighting track (2) is specifically as follows: Sp1: Monitoring and early warning: The temperature sensors on the inner and outer walls of the power distribution cabinet (1) and the smoke alarm 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 the smoke alarm send a signal to the controller; Sp2: Startup 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 support arm (17) to open from the inside of the storage recovery slot (5), so that the linear fire-fighting support arm (17) is in the initial position ready for fire extinguishing; Sp3: Material supply and transmission: The controller controls the material storage box (14) to guide the fire extinguishing material into the U-shaped spraying cavity (18) through the material guide pipe (15), and provides the linear fire extinguishing support arm (17) and the rotating fire extinguishing support arm (21) with the materials required for fire extinguishing. For the rotating fire extinguishing support arm (21), when the second electric control valve (25) at the end of the rotating fire extinguishing support arm (21) overlaps with the first electric control valve (20), the controller controls the opening of the two electric control valves to make the U-shaped spraying cavity (18) and the cavity inside the rotating fire extinguishing support arm (21) connected, so as to realize the transmission of materials to the inside of the rotating fire extinguishing support arm (21). After the material supply is completed, the controller controls the two to close; Sp4: Fire extinguishing operation: The spray holes (22) on the surfaces of the linear fire extinguishing support arm (17) and the rotating fire extinguishing support arm (21) begin to spray fire extinguishing materials to extinguish the fire. At the same time, the controller controls the telescopic cylinder (23) to push the rotating fire extinguishing support arm (21) out from the inside of the linear fire extinguishing support arm (17), and controls the electric shaft (24) to drive the rotating fire extinguishing support arm (21) to rotate, and extinguishes the fire in the high altitude range through the spray holes (22) to expand the fire extinguishing coverage area. The controller adjusts the working state of the angle adjustment motor (16), the electric shaft (24) and the telescopic cylinder (23) in real time according to the information fed back by the temperature sensor, the smoke alarm and the 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 support arm (17) and the rotating fire extinguishing support arm (21) are accurately adjusted so that the spray holes (22) can be accurately aimed at the fire source for efficient fire extinguishing. Sp5: Material recovery: During the fire extinguishing process, the controller starts the vacuum pump (11), and the vacuum pump (11) recovers the ejected material by negative pressure through the air guide pipe (12) and the negative pressure hole (9), thereby preventing the material from accumulating around the power distribution cabinet body (1), reducing 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 the smoke alarm detect that the temperature and smoke density inside the power distribution cabinet body (1) return to normal, that is, the fire is extinguished, the controller controls the angle adjustment motor (16) to retract the linear fire extinguishing support arm (17) into the storage recovery slot (5), and at the same time controls the telescopic cylinder (23) to retract the rotating fire extinguishing support arm (21) into the linear fire extinguishing support arm (17), so that the entire fire-fighting device returns to the initial state and waits for the next fire monitoring and alarm.
