Description

Technical Field

[0001] This invention relates to the field of control cabinet technology, and in particular to an intelligent power control cabinet with electrical safety protection. Background Technology

[0002] As a core piece of equipment in the power system, electrical control cabinets are widely used in various power generation, distribution, and substations. Their core functions include real-time display of various electrical parameters during operation through measuring instruments, and support for precise adjustment of key parameters; under normal operating conditions, circuit connection and disconnection can be controlled manually or automatically; when equipment deviates from normal operating conditions, protective electrical devices can promptly issue warning signals or directly cut off the circuit to prevent the fault from escalating, thus providing an important guarantee for the stable operation of the power system.

[0003] In practical applications, traditional electrical control cabinets have gradually revealed their insufficient adaptability, mainly in terms of extreme environmental adaptability: In the high-temperature environment of summer, the heat continuously generated by the internal electronic components during operation is difficult to dissipate efficiently through the existing heat dissipation structure, resulting in the temperature inside the cabinet accumulating and rising, directly affecting the working stability of the electronic components, and even causing equipment failure, threatening the safe operation of the power system; while control cabinets equipped with photovoltaic panels as emergency power sources to achieve energy saving and consumption reduction are prone to frost or snow accumulation on the surface of the photovoltaic panels in the low-temperature environment of winter, blocking the light-receiving surface, resulting in a significant decrease in solar energy conversion efficiency, which cannot meet the emergency power supply needs. In response to the above problems, Chinese patent with announcement number "CN114040623B" discloses a dual-purpose intelligent energy-saving electrical control cabinet for both heating and cooling. This device sets up a liftable cover on the top of the cabinet, installs photovoltaic panels on the top surface of the cover, and is equipped with a sliding cleaning mechanism, a heat dissipation mechanism, and a ventilation mechanism, realizing the dual functions of efficient heat dissipation in summer and snow and frost removal for photovoltaic panels in winter, which improves the operational stability of the control cabinet in extreme temperature environments to a certain extent and has significant energy-saving effects;

[0004] Although the aforementioned patented solutions have solved the temperature adaptability problem, key safety protection deficiencies still exist in practical applications: Currently, electrical intelligent energy-saving control cabinets integrate a large number of electronic components and circuits, and the components are densely arranged and the circuits are intertwined and close together. During long-term operation, short circuit faults are easily caused by circuit aging, insulation damage, etc. When a short circuit occurs, a large amount of heat is generated instantly, causing the temperature inside the cabinet to rise sharply, which in turn causes a fire hazard. However, the existing technology lacks targeted fire prevention design and cannot prevent the occurrence and spread of fire from the source. Its safety protection performance is insufficient and it is difficult to meet the high safety requirements of power equipment. Therefore, further improvement and optimization are urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent power control cabinet with power safety protection to solve the problems mentioned in the background art.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Firstly, in this invention, during the application of this technical solution, by setting up a fire prevention device, it is possible to monitor fire hazards inside the cabinet in real time and promptly initiate fire extinguishing operations, thereby achieving the effect of containing the fire from its initial stage. This solves the problem that existing electrical control cabinets lack effective fire prevention design and cannot cope with the risk of fire caused by internal short circuits. The fire detection sensor in the fire prevention device can capture abnormal signals such as internal temperature and smoke in real time. The supply mechanism can stably provide the extinguishing agent required for fire extinguishing. The drive mechanism drives the fire extinguishing mechanism to rotate and move up and down, ensuring that the extinguishing agent covers the inside of the cabinet in all directions through the fire extinguishing nozzle, preventing the fire from spreading. At the same time, the pressure gauge of the supply mechanism can monitor the extinguishing agent storage in real time. The lifting ring and the corrective load ball of the fire extinguishing mechanism can ensure the stable operation of the extinguishing agent delivery hose. The synergistic effect of all parts greatly improves the safety protection performance of the control cabinet and reduces equipment damage and safety accidents caused by fire.

[0024] Firstly, in this invention, the technical solution utilizes a convenient maintenance mechanism to facilitate the inspection and maintenance of electronic components inside the cabinet during use. This improves maintenance efficiency and reduces operational difficulty, solving the problems of densely packed components inside electrical control cabinets, requiring personnel to penetrate deep into the cabinet for maintenance, leading to inconvenience and potential malfunctions. The lateral movement module of the convenient maintenance mechanism can move the entire load-bearing module out of the cabinet. The load-bearing module stably supports the electronic component mounting frame, which can slide along the rail. This allows personnel to inspect or replace components without entering the cabinet. Simultaneously, the magnetic suction plate within the rail ensures the frame remains stable during normal operation. The connecting rod links the load-bearing module to the cabinet door; opening the door allows the module to be moved out. Combined with the touch control operation of the controller, this further simplifies the maintenance process and reduces the risk of equipment failure due to improper maintenance operations.

[0035] Example

[0036] Please see Figures 1-9 In this embodiment of the invention, an intelligent power control cabinet with power safety protection includes a cabinet body 1 and a fireproof device 2. A base plate 3 is welded to the bottom of the cabinet body 1. A convenient maintenance mechanism 4 is installed inside the cabinet body 1. The fireproof device 2 is arranged on the outside of the convenient maintenance mechanism 4. The front of the cabinet body 1 is covered with a cabinet door 5. The rear side of the cabinet door 5 is connected to the front side of the convenient maintenance mechanism 4.

[0037] Fire protection device 2 includes a supply mechanism 21, a drive mechanism 22, a fire detection sensor 24, and a fire extinguishing mechanism 23. The supply mechanism 21 is fixedly connected to the middle of the back of cabinet 1. The drive mechanism 22 is fixedly connected to the top of cabinet 1. The fire extinguishing mechanism 23 is movably installed inside the top of cabinet 1. The top of the fire extinguishing mechanism 23 is connected to the bottom output end of the drive mechanism 22. The input end of the fire extinguishing mechanism 23 is connected to the supply mechanism 21 through the drive mechanism 22. The fire detection sensor 24 is fixedly connected to one side of the top inside cabinet 1. During application, the cabinet, fireproof device 2, and convenient maintenance mechanism 4 are designed to meet the maintenance needs of internal components while preventing fire risks. The base plate 3 at the bottom of the cabinet 1 provides stable support for the entire structure. The cabinet door 5 on the front of the cabinet 1 is connected to the convenient maintenance mechanism 4. When it is necessary to maintain the internal components of the cabinet 1, opening the cabinet door 5 will activate the convenient maintenance mechanism 4, allowing personnel to access the convenient maintenance mechanism 4 without having to go inside the cabinet 1, facilitating the inspection or maintenance of relevant components. This design reduces the complexity of maintenance operations. Meanwhile, the fireproof device 2, located outside the convenient maintenance mechanism 4, provides constant protection. The fire detection sensor 24 within the fireproof device 2 is installed on the top of the cabinet 1, allowing real-time monitoring for signs of fire inside the cabinet 1. Upon detection of an anomaly, the supply mechanism 21 of the fireproof device 2 activates to provide the necessary fire-fighting materials. The drive mechanism 22 then operates, driving the fire-extinguishing mechanism 23. Since the input of the fire-extinguishing mechanism 23 is connected to the supply mechanism 21 via the drive mechanism 22, the fire-extinguishing materials provided by the supply mechanism 21 are transported to the fire-extinguishing mechanism 23 via the drive mechanism 22. The fire-extinguishing mechanism 23 then extinguishes the fire inside the cabinet 1, effectively preventing the spread of fire. This design solves the problem of inconvenient maintenance operations in existing electrical control cabinets and compensates for the lack of targeted fire prevention measures in existing technologies. It enhances the convenience and safety of the device, ensuring more reliable operation and reducing equipment failures or safety accidents caused by maintenance difficulties or fire hazards.

[0038] Please see Figures 1-6The convenient maintenance mechanism 4 includes a horizontal movement module 41 and a load-bearing module 42. The horizontal movement module 41 is located in the middle of the bottom of the cabinet 1. The load-bearing module 42 is fixedly installed on the top moving end of the horizontal movement module 41. The horizontal movement module 41 includes a slide 411, which is located in the middle of the bottom of the cabinet 1. A first lead screw 412 is rotatably connected inside the slide 411. A slider 413 is threadedly connected to the outer surface of the first lead screw 412. The slider 413 is slidably connected inside the slide 411. A first motor 414 is installed at the rear end of the slide 411 by screws. The output end of the first motor 414 is connected to the rear end of the first lead screw 412 through a coupling. The load-bearing module 42 includes a base plate 421. The bottom of the base plate 421 is far from the cabinet door 5. A connecting plate 422 is fixedly connected to the side. The end of the connecting plate 422 away from the base plate 421 is bolted to the top of the slider 413. A bearing frame 423 is bolted to the top of the base plate 421. A rail frame 424 is linearly arranged at equal intervals inside the bearing frame 423 and screwed on. Electronic component mounting frames 425 are slidably connected inside the rail frame 424. A magnetic suction plate 426 is screwed to the rear side of the inside of the rail frame 424. The magnetic suction plate 426 is used to attract the electronic component mounting frames 425 to ensure that they are inside the rail frame 424. A connecting rod 427 is welded to the middle of the side of the base plate 421 away from the first motor 414. The outer end of the connecting rod 427 is connected to the cabinet door 5. A controller is provided at the top of the cabinet door 5. 6. The controller 6 has a touch screen on the front. During the application of this device, the convenient maintenance mechanism 4 makes it easier for staff to perform maintenance on the electronic components inside the cabinet 1 without having to go deep into the cabinet 1. When staff need to repair the electronic components, they open the cabinet door 5. Since the cabinet door 5 is connected to the base plate 421 through the connecting rod 427, opening the cabinet door 5 will cause the base plate 421 to move synchronously. If it is necessary to further adjust the position of the bearing module 42, a command can be issued through the touch screen of the controller 6 at the top of the cabinet door 5 to start the first motor 414 at the rear end of the slide 411. The output end of the first motor 414 drives the first lead screw 412 to rotate through the coupling. When 412 rotates, it drives the slider 413, which is threaded on its outer surface, to slide along the inside of the slide groove 411. The slider 413 is fixed to the base plate 421 via the connecting plate 422, thereby driving the entire support module 42 to move smoothly out of the cabinet 1. This avoids the inconvenience of workers having to crawl into the cabinet 1 to operate. The top of the base plate 421 of the support module 42 is bolted to a support frame 423. The linearly arranged rails 424 at equal intervals inside the support frame 423 provide a mounting carrier for the electronic component mounting frame 425. The electronic component mounting frame 425 can slide along the inside of the rails 424. Workers only need to pull the frame out of the rails 424 to inspect or replace the electronic components on the frame without disassembling the entire support frame 423.The magnetic plate 426 on the rear side of the rail frame 424 exerts an attractive force on the electronic component mounting frame 425 during normal operation, ensuring the frame remains stably within the rail frame 424. This prevents displacement due to slight vibrations of the cabinet 1 or shaking caused by equipment operation, thus guaranteeing a normal working environment for the electronic components. This design solves the problem of existing electrical control cabinets requiring deep access to confined spaces for maintenance, and reduces the risk of component damage due to frame displacement through the stabilizing effect of the magnetic plate 426. Furthermore, the touch operation of the controller 6 simplifies the movement control of the carrying module 42, improving maintenance efficiency and safety.

[0039] Please see Figures 1-4The supply mechanism 21 includes an annular fixing frame 211, which is welded to the lower back of the cabinet 1. An extinguishing agent compression tank 212 is bolted to the inner side of the annular fixing frame 211. An opening and closing solenoid valve 213 is welded to the top of the extinguishing agent compression tank 212. The output end of the opening and closing solenoid valve 213 is sealed to a high-pressure delivery hose 214 via a threaded joint. The output end of the high-pressure delivery hose 214 is connected to the drive mechanism 22. A pressure gauge 215 is welded to the upper side of one side of the extinguishing agent compression tank 212. The pressure detection end of the pressure gauge 215 is located on the extinguishing agent compression tank 212. Inside the device, during application, the supply mechanism 21 ensures a stable supply of extinguishing agent to meet the fire-fighting needs inside the cabinet 1. This also allows staff to monitor the extinguishing agent reserves in real time. When a fire hazard arises inside the cabinet 1 and the fire-fighting process needs to be initiated, a relevant control signal triggers the solenoid valve 213 on top of the extinguishing agent compression tank 212. Upon receiving the signal, the solenoid valve 213 opens, and the high-pressure extinguishing agent stored in the compression tank 212 is delivered to the drive mechanism 22 via the high-pressure delivery hose 214 at the output of the solenoid valve 213. The extinguishing agent is then transported by the drive mechanism... The actuation mechanism 22 transfers the extinguishing agent to the subsequent extinguishing mechanism 23, ensuring that the extinguishing mechanism 23 receives sufficient extinguishing agent in a timely manner to complete the fire extinguishing operation and preventing the fire from spreading due to insufficient extinguishing agent supply. During daily use, personnel can check the pressure inside the extinguishing agent compression tank 212 through the pressure gauge 215 on the upper side of one side. Since the pressure detection end of the pressure gauge 215 is located inside the extinguishing agent compression tank 212, it can accurately reflect the remaining amount of extinguishing agent in the tank. When the pressure gauge 215 shows that the pressure is too low, personnel can replace the extinguishing agent compression tank 212 in a timely manner to ensure the supply of the mechanism. 21 is always in a ready-to-use state to avoid affecting the fire extinguishing effect due to insufficient fire extinguishing agent. In addition, the ring-shaped fixing frame 211 can stably fix the fire extinguishing agent compression tank 212 to the lower back of the cabinet 1, preventing the fire extinguishing agent compression tank 212 from shifting or tipping over during the operation of the device or when affected by external forces, and ensuring the overall stability of the supply mechanism 21. This design not only solves the problems of unstable fire extinguishing agent supply and difficulty in timely monitoring of reserve status during fire extinguishing in the existing technology, but also ensures the safety of use of the supply mechanism 21 through the fixed structure, providing reliable material supply support for the fire protection function of the cabinet 1.

[0040] Please see Figures 5-9 The drive mechanism 22 includes a drive assembly 221 and a transmission assembly 222. The drive assembly 221 is fixedly connected to one side of the top of the cabinet 1, and the transmission assembly 222 is movably installed in the middle of the top of the cabinet 1. The drive assembly 221 and the transmission assembly 222 are connected in a transmission manner.

[0041] The transmission assembly 222 includes a movable ring 2221 and a rotary joint 2222. The rotary joint 2222 is rotatably connected to the top center of the cabinet 1. The movable ring 2221 is rotatably connected to the top of the cabinet 1 and located outside the rotary joint 2222. The outer side of the movable ring 2221 is welded to an external gear ring 2223. The drive assembly 221 and the external gear ring 2223 are connected in a transmission manner. A connecting frame 2224 is welded to the top of the movable ring 2221. The inner side of the connecting frame 2224 is fixedly connected to the upper end of the outer surface of the rotary joint 2222. The drive assembly 221 includes a side arm 2211. The side arm 2211 is installed on one side of the top of the cabinet 1 by screws. A second motor 2212 is installed on the top of the side arm 2211 by screws. The second motor 2212 outputs... An external gear 2213 is fixedly connected to the upper end of the through side arm 2211. The external gear 2213 and the external gear ring 2223 are meshed together. The top of the cabinet 1 is fitted with a cover shell 2214 by screws. The cover shell 2214 covers the outside of the drive assembly 221 and the transmission assembly 222. The input end of the rotary joint 2222 is connected to the opening and closing solenoid valve 213 on the top of the fire extinguishing agent compression tank 212 through the high pressure delivery hose 214. The fire extinguishing mechanism 23 includes a connecting rod 231 and a linkage assembly 232. The connecting rod 231 is fixedly connected to the bottom two sides of the rotary joint 2222. A vertical moving assembly 233 is fixedly connected to the outside of the connecting rod 231. The linkage assembly 232 is located at the top of the cabinet 1 and is connected to the vertical moving assembly 233 in a transmission manner.

[0042] The vertical moving assembly 233 includes a vertical rail 2331, which is installed on the outer end of the connecting rod 231 by screws. The interior of the vertical rail 2331 is rotatably provided with a second lead screw 2332 via ball bearings. The outer surface of the second lead screw 2332 is threaded with a longitudinal sliding block 2333. The inner side of the longitudinal sliding block 2333 is installed with a transverse conveying pipe 2334 by screws. The top of the transverse conveying pipe 2334 is connected to the bottom rotating conveying end of the rotary joint 2222 via a high-pressure conveying hose 214. The inner side of the transverse conveying pipe 2334 is integrally formed with fire extinguishing nozzles 2335 at equal intervals.

[0043] It also includes a lifting ring 2336, which is fixedly connected to the bottom outer end of the connecting rod 231. The high-pressure conveying hose 214 on the transverse conveying pipe 2334 passes through the inside of the lifting ring 2336. A corrective load ball 2337 is fixedly connected to the bottom of the high-pressure conveying pipe near the rotary joint 2222. The corrective load ball 2337 is used to adjust the tension of the high-pressure conveying pipe by the longitudinal sliding block 2333 and to adaptively slide and extend to avoid tangling.

[0044] The linkage component 232 includes a fixing ring 2321, which is installed on the top of the cabinet 1 by screws. The fixing ring 2321 is located on the outside of the output end of the rotary joint 2222, and an internal toothed ring 2322 is installed on the bottom of the fixing ring 2321 by screws.

[0045] It also includes an internal gear 2323, which is rotatably connected to the top of the vertical rail 2331. The bottom of the internal gear 2323 is connected to the top of the second lead screw 2332 via a coupling. The internal gear 2323 and the outer side of the internal gear ring 2322 are meshed. During the application of this device, by setting up a drive mechanism 22 and a fire extinguishing mechanism 23, it can accurately and comprehensively deliver the fire extinguishing agent supplied by the supply mechanism 21 to the area inside the cabinet 1 that needs fire extinguishing, effectively addressing fire hazards. When the fire extinguishing operation needs to be initiated, the second motor 2212 of the drive assembly 221 will start working. The output end of the second motor 2212 drives the external gear 2213 to rotate. Since the external gear 2213 and the external gear ring 222 of the transmission assembly 222 are meshed together, the internal gear 2323 is connected to the top of the vertical rail 2331. 3. When engaged, the external gear ring 2223 will drive the movable ring 2221 to rotate. The movable ring 2221 drives the rotary joint 2222 to rotate synchronously through the connecting frame 2224. The input end of the rotary joint 2222 is connected to the opening and closing solenoid valve 213 of the fire extinguishing agent compression tank 212 through the high-pressure delivery hose 214. At this time, the fire extinguishing agent delivered by the supply mechanism 21 will enter the rotary joint 2222. At the same time, the connecting rods 231 on both sides of the bottom of the rotary joint 2222 will rotate with the rotary joint 2222. The vertical rail 2331 on the outer side of the connecting rod 231 will also rotate. The internal gear 2323 at the top of the vertical rail 2331 meshes with the internal gear ring 2322 of the linkage component 232. When the vertical rail 2331 rotates, the internal gear 2323 will roll along the internal gear ring 2322. The device rotates itself, which in turn drives the second lead screw 2332 inside the vertical rail 2331 to rotate via the coupling. The rotation of the second lead screw 2332 drives the longitudinal sliding block 2333, which is threaded on its outer surface, to move up and down along the vertical rail 2331. The transverse conveying pipe 2334 inside the longitudinal sliding block 2333 also moves up and down synchronously. The top of the transverse conveying pipe 2334 is connected to the bottom rotating conveying end of the rotary joint 2222 via a high-pressure conveying hose 214. The extinguishing agent in the rotary joint 2222 enters the transverse conveying pipe 2334 through the high-pressure conveying hose 214, and then sprays out from the extinguishing nozzle 2335 inside the transverse conveying pipe 2334, achieving fire extinguishing coverage at different heights and positions inside the cabinet 1. During the movement of the transverse conveying pipe 2334... The high-pressure delivery hose 214, which passes through the lifting ring 2336, remains stable. The corrective weight ball 2337 exerts a downward pulling force on the high-pressure delivery hose 214, ensuring that the hose is always taut. At the same time, when the longitudinal sliding block 2333 moves up and down, it assists the hose in adaptive sliding and expansion, preventing the hose from tangling and affecting the delivery of extinguishing agent. In addition, the cover shell 2214 on the top of the cabinet 1 can cover the drive assembly 221 and the transmission assembly 222, preventing external dust and impurities from entering and affecting the operation of the components. This design not only solves the problems of limited coverage of the extinguishing mechanism 23 and easy interference with the delivery of extinguishing agent in the existing technology, but also realizes the rotation and up and down movement of the extinguishing mechanism 23 through the linkage structure, ensuring the comprehensiveness and stability of extinguishing.This improved the fire resistance of the device.

[0046] The working principle of this invention is as follows: In daily use, the convenient maintenance mechanism 4 of this intelligent power control cabinet with power safety protection can meet the maintenance needs of staff for the electronic components inside the cabinet 1. When the staff opens the cabinet door 5, the rear side of the cabinet door 5 is connected to the base plate 421 of the bearing module 42 in this convenient maintenance mechanism 4 via a connecting rod 427. The bottom side of the base plate 421 away from the cabinet door 5 is fixed to the slider 413 of the transverse module 41 via a connecting plate 422. The slider 413 is threaded to the outer surface of the first lead screw 412 inside the slide groove 411. Therefore, when the cabinet door 5 is opened, the base plate 421 will be pulled by the connecting rod 427. The base plate 421 drives the slider 413 to slide along the slide groove 411 via the connecting plate 422. At this time, if it is necessary to assist the movement of the base plate 421, a command can be issued through the touch screen of the controller 6 to start the first motor 414 at the rear end inside the slide groove 411. The output end of the first motor 414 drives the first lead screw 412 to rotate through the coupling. During the rotation of the first lead screw 412, the first lead screw drives the first motor 412 to rotate. The slider 413 slides stably along the slide groove 411, thereby driving the substrate 421 and the supporting module 42 above it to move out of the cabinet 1 simultaneously. The top of the substrate 421 of the supporting module 42 is fixed with a supporting frame 423 by bolts. The rails 424 arranged linearly at equal intervals inside the supporting frame 423 are used to support the electronic component mounting frame 425. The electronic component mounting frame 425 can slide along the inside of the rails 424, making it convenient for staff to pull it out for component inspection or replacement; the rear side of the inside of the rails 424 The magnetic plate 426 can generate an adsorption force on the electronic component mounting frame 425, ensuring that the electronic component mounting frame 425 is stably located inside the rail frame 424 when the cabinet 1 is running normally, avoiding frame displacement due to slight vibration of the cabinet 1. After maintenance is completed, push the cabinet door 5, or start the first motor 414 to rotate in the reverse direction through the controller 6, which drives the first lead screw 412 to drive the slider 413 to reset along the slide groove 411. The substrate 421 returns to the cabinet 1 with the slider 413, the cabinet door 5 closes, and the maintenance operation is completed.

[0047] When a fire hazard arises inside cabinet 1 due to a short circuit or other reasons, the fire detection sensor 24 at the top of cabinet 1 will monitor the internal temperature, smoke, and other fire signs in real time. If an abnormality is detected, it will immediately transmit a signal to the controller 6 at the top of cabinet door 5. After receiving the signal, controller 6 will first control the opening and closing of the solenoid valve 213 of the supply mechanism 21 in this fire protection device 2. The annular fixing bracket 211 of this supply mechanism 21 is welded to the lower back of cabinet 1 to fix the fire extinguishing agent compression tank 212 and ensure the fire extinguishing agent compression tank 212 is secure. 12. The pressure gauge 215 on the upper side of the fire extinguishing agent compression tank 212 can detect the pressure inside the tank in real time. During routine maintenance, the staff can use the pressure gauge 215 to determine whether the fire extinguishing agent in the tank is sufficient, so as to avoid the fire extinguishing effect being affected by insufficient pressure. After the solenoid valve 213 is opened, the fire extinguishing agent in the fire extinguishing agent compression tank 212 is delivered to the rotary joint 2222 of the drive mechanism 22 through the high-pressure delivery hose 214. At the same time, the controller 6 controls the second motor 2212 of this drive mechanism 22 to start. The side arm 2211 of the drive mechanism 22 is fixed to one side of the top of the cabinet 1 by screws to support the second motor 2212. The output end of the second motor 2212 passes through the upper end of the side arm 2211 and is fixedly connected to the external gear 2213. The external gear 2213 meshes with the external gear ring 2223 of the transmission assembly 222. Therefore, after the second motor 2212 starts, it drives the external gear 2213 to rotate, and the external gear 2213 drives the external gear ring 2223 to rotate. The external gear ring 2223 is welded to the outside of the movable ring 2221. 21 is rotatably connected to the top of the cabinet 1 and located outside the rotary joint 2222. The movable ring 2221 is fixed to the upper end of the outer surface of the rotary joint 2222 via the connecting frame 2224. Therefore, when the outer toothed ring 2223 drives the movable ring 2221 to rotate, the connecting frame 2224 simultaneously drives the rotary joint 2222 to rotate along the top of the cabinet 1. The cover shell 2214 on the top of the cabinet 1 covers the outside of the drive assembly 221 and the transmission assembly 222, which can prevent external dust and impurities from entering the drive and transmission structures and avoid affecting the transmission accuracy.

[0048] During the rotation of the rotary joint 2222, the connecting rods 231 on both sides of its bottom rotate synchronously with the rotary joint 2222. The vertical rail 2331 fixed on the outside of the connecting rod 231 rotates around the axis of the rotary joint 2222. At the same time, the linkage component 232 of this fire extinguishing mechanism 23 functions. The fixing ring 2321 of the linkage component 232 is installed on the top of the cabinet 1 by screws. The internal gear ring 2322 at the bottom of the fixing ring 2321 remains fixed. The internal gear 2323 rotatably connected to the top of the vertical rail 2331... The internal gear ring 2322 engages with the outer side. When the vertical rail 2331 rotates with the rotary joint 2222, the internal gear 2323 rolls along the outer side of the internal gear ring 2322 and rotates itself. The bottom of the internal gear 2323 drives the second lead screw 2332 inside the vertical rail 2331 to rotate through a coupling. The longitudinal sliding block 2333, which is threaded to the outer surface of the second lead screw 2332, moves up and down along the inside of the vertical rail 2331 under the action of the rotation of the second lead screw 2332. The inner side of the longitudinal sliding block 2333 is fixed by screws. The transverse conveying pipe 2334 moves up and down synchronously with the longitudinal sliding block 2333. The top of the transverse conveying pipe 2334 is connected to the rotating conveying end at the bottom of the rotary joint 2222 via a high-pressure conveying hose 214. The extinguishing agent conveyed by the rotary joint 2222 enters the transverse conveying pipe 2334 through the high-pressure conveying hose 214, and is then sprayed out through the extinguishing nozzles 2335 integrally formed at equal intervals on the inner side of the transverse conveying pipe 2334, realizing the fire extinguishing operation inside the cabinet 1. The bottom outer end of the connecting rod 427 is fixed with a hanging... Ring 2336 is used to pass through the high-pressure delivery hose 214 on the transverse delivery pipe 2334 to prevent the hose from swaying randomly during the movement of the transverse delivery pipe 2334; the correction weight ball 2337 fixed at the bottom of the high-pressure delivery hose 214 near the rotary joint 2222 can generate a downward pulling force on the hose to keep the hose taut. At the same time, when the longitudinal sliding block 2333 moves up and down, it assists the hose to adapt to sliding and expanding, avoiding the hose from getting tangled due to rotation or movement, and ensuring stable delivery of extinguishing agent.

[0049] This technical solution effectively addresses the problems existing in the background technology: The background technology points out that existing improvement solutions lack fire-resistant design and cannot contain fire hazards. This solution achieves a synergistic effect of all-round fire extinguishing through real-time monitoring by the fire detection sensor 24, supply of extinguishing agent by the supply mechanism 21, rotation of the extinguishing mechanism 23 by the drive mechanism 22, and vertical movement of the extinguishing mechanism 23. From fire detection to extinguishing agent spraying, a complete fire prevention process is formed, which can extinguish the fire source in its early stages, solving the problem of insufficient safety protection performance in existing technologies. Simultaneously, this convenient maintenance mechanism 4 drives the load-bearing module 41 through the transverse movement module 41. Group 42 enters and exits cabinet 1. The electronic component mounting frame 425 can slide along the rail frame 424, allowing staff to complete maintenance without entering the cabinet 1, reducing the probability of malfunctions caused by improper maintenance operations and further improving the safety and convenience of the control cabinet. The pressure gauge 215 of the supply mechanism 21 can monitor the extinguishing agent storage in real time. The housing 2214 of the drive mechanism 22 protects the transmission structure. The lifting ring 2336 and the straightening load ball 2337 of the fire extinguishing mechanism 23 ensure stable delivery of the hose. All structures cooperate with each other to ensure the stable realization of the fire prevention and maintenance functions of the control cabinet.
