Description

Technical Field

[0001] This invention relates to the field of monitoring device technology, and in particular to an intelligent power fire monitoring device. Background Technology

[0002] When electrical equipment is installed in a power distribution room or cabinet, smoke detectors or similar early warning devices are typically added to prevent fires caused by faults such as leakage, short circuits, poor contact, or aging wiring. Additionally, surveillance cameras are often installed for security reasons. With technological advancements, fire monitoring and early warning functions can now be added to these cameras. AI can be used to capture smoke or accurately identify electric arcs, thus enabling fire monitoring and early warning.

[0003] In practical applications of surveillance cameras, since they are generally installed at high locations, the smoke generated by power equipment due to a fault may be located at a lower level or blocked by other power equipment. This causes a delay in the actual monitoring process, which can lead to the further development of the fault or even directly develop into a fire. This results in untimely monitoring of power equipment. Furthermore, once a fire forms, the difference in location or obstruction by power equipment can also cause untimely warnings, preventing the fire from being effectively contained and ultimately causing severe damage to the power equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent power fire monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A smart fire monitoring device for power systems includes a monitoring mounting bracket and a monitoring host, wherein the monitoring host is mounted on the monitoring mounting bracket.

[0007] It also includes an active extraction and detection device, which is installed on the monitoring mounting bracket and is used to actively extract smoke. The active extraction and detection device includes a smoke hood, which is installed on the monitoring mounting bracket. An exhaust fan is installed on the monitoring mounting bracket, and a follow-up smoke extraction pipe is connected to the exhaust fan. The follow-up smoke extraction pipe is installed on the smoke hood, and multiple smoke extraction heads are installed on the smoke hood.

[0008] The monitoring mounting bracket is equipped with a linkage lifting device, and the active extraction detection device is mounted on the linkage lifting device. The linkage lifting device is used to drive the active extraction detection device to move up and down. The linkage lifting device includes a lifting drive seat, which is mounted on the fume hood. A drive rotating column is rotatably mounted inside the lifting drive seat. The drive rotating column is connected to the exhaust fan. When the exhaust fan is started, it drives the drive rotating column to rotate, thereby driving the lifting drive seat to move up and down.

[0009] The active extraction and detection device is equipped with an emergency fire extinguishing device for emergency fire suppression of electrical equipment. The emergency fire extinguishing device includes four fire extinguishers, which are respectively installed on the top sides of the four sides of the fume hood.

[0013] An extension adapter shaft is installed on the output shaft of the exhaust fan. The extension adapter shaft passes through the smoke inlet filter plate. A rotating brush strip is installed on the extension adapter shaft. The rotation of the extension adapter shaft drives the rotating brush strip to rotate, which is used to clean the smoke inlet filter plate.

[0014] Furthermore, in a preferred embodiment of the present invention, the smoke hood has multiple connecting holes on all four sides, and the multiple smoke heads are respectively inserted into the multiple connecting holes;

[0015] An emergency stop switch is installed on the inner wall of the bottom of all four sides of the fume hood, and the emergency stop switch is electrically connected to the exhaust fan.

[0016] Furthermore, in a preferred embodiment of the present invention, the linkage lifting device further includes four guide rods, which are mounted on the monitoring mounting bracket;

[0017] The smoke hood has guide holes at each of its four corners, and the four guide rods are respectively movably installed in the four guide holes.

[0018] Furthermore, in a preferred embodiment of the present invention, bottom brackets are installed on the bottom sides of the two guide rods located on the same side, and a rotating groove is provided on one of the bottom brackets, and the driving rotating column is rotatably installed in the rotating groove;

[0019] The inner wall of the rotating groove is provided with a telescopic groove, and a wedge-shaped locking rod is movably installed in the telescopic groove. Multiple wedge-shaped slots are provided in a ring at equal intervals on the driving rotating column, and the wedge-shaped locking rod is locked in one of the wedge-shaped slots at a corresponding position.

[0020] An ejector spring is installed on the inner wall of the telescopic groove, and the ejector spring is mounted on the wedge-shaped clamp.

[0021] Furthermore, in a preferred embodiment of the present invention, a rotating hole is provided on the lifting drive seat, and the driving rotating column is rotatably installed in the rotating hole;

[0022] A drive ring groove is provided on the drive rotating column, and a drive block is installed on the inner wall of the rotating hole, with the drive block extending into the drive ring groove.

[0023] Furthermore, in a preferred embodiment of the present invention, a transfer rotating shaft is rotatably mounted on the transfer cover, and the transfer rotating shaft is mounted on the drive rotating column;

[0024] A drive gear is mounted on the extension adapter shaft, and an amplifying gear is mounted on the adapter rotating shaft. The drive gear meshes with the amplifying gear.

[0025] Furthermore, in a preferred embodiment of the present invention, the emergency fire extinguishing device further includes multiple limiting support rods, and two pull-down holes are provided on each of the four sides of the smoke hood, with pull-down brackets movably installed in the two pull-down holes on the same side.

[0026] The conversion bracket is mounted on the two pull-down brackets, and the limiting support rod is inserted into the fume hood and the pull-down brackets.

[0027] Furthermore, in a preferred embodiment of the present invention, a squeeze handle is installed on the bottom side of the fire extinguisher, and the conversion bracket is moved down to squeeze the squeeze handle;

[0028] Two pull-down springs are installed on the top side of the conversion bracket, and the two pull-down springs are installed on the inner wall of the smoke hood.

[0029] The beneficial effects of the intelligent power fire monitoring device proposed in this invention are:

[0030] In this invention, by setting up an active extraction detection device, when the monitoring host is installed in a power distribution room or power cabinet, the exhaust fan is activated, causing the air around the electrical equipment to be drawn into the fume hood by multiple smoke extraction heads. The air then enters the transfer hood through a follow-up smoke extraction pipe, then enters the exhaust fan through the transfer hood, and finally enters the smoke guide hood through the exhaust hood before being delivered to the monitoring host. Therefore, if electrical equipment burns out and generates smoke, the active extraction of smoke allows the monitoring host to detect it more promptly, enabling faster action and preventing damage to the electrical equipment due to monitoring delays. It also effectively avoids monitoring blind spots caused by obstruction between electrical devices.

[0031] Furthermore, in this invention, by setting up a linkage lifting device, when the exhaust fan drives the extension adapter shaft to rotate, it drives the drive gear to rotate, which in turn drives the amplifying gear to rotate. The rotation of the amplifying gear drives the drive rotating column to rotate through the adapter rotating shaft. The drive rotating column rotates within the rotating hole. Simultaneously, when the drive rotating column rotates, it drives the drive block to move through the drive ring groove. The movement of the drive block drives the lifting drive seat to move, and the movement of the lifting drive seat drives the fume hood to move. This causes the fume hood to move vertically up and down, achieving the purpose of fully extracting the smoke around the power equipment, further improving the monitoring efficiency of the monitoring host. It should be noted that in the event of a fire that causes the exhaust fan to stop abruptly, the wedge-shaped lever can be inserted into the corresponding wedge-shaped slot, stopping the smoke hood in that position. This allows for effective and continuous fire suppression at that location, ensuring the safety of the electrical equipment. Simultaneously, the amplifying gear design ensures that when the drive gear rotates multiple times, it drives the amplifying gear to rotate one full turn, causing the smoke hood to move vertically once. This also reduces the speed of the smoke hood during vertical lifting and lowering, ensuring effective air extraction around the electrical equipment and improving the accuracy of smoke detection by the monitoring host.

[0032] Furthermore, in this invention, by setting up an emergency fire extinguishing device, when the monitoring equipment is monitoring the electrical equipment, if a fire occurs on one side, the limiting support rod on the corresponding side will soften due to heat and lose its supporting force. At this time, under the contraction force of the two pull-down springs, the conversion bracket will move down. At this time, the positions of multiple spray branches correspond to multiple smoke extraction heads. Simultaneously, the downward movement of the conversion bracket will press down the squeeze handle. At this time, the fire extinguisher will deliver the extinguishing material through the spray pipe to the multiple spray branches, and then spray it out through the multiple smoke extraction heads to achieve the function of active fire extinguishing. In addition, the downward movement of the conversion bracket will press down and trigger the emergency stop switch, causing the exhaust fan to stop abruptly and the smoke extraction hood to stay at the position of the fire, achieving precise fire extinguishing and further protecting the safety of the electrical equipment.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] Please refer to the attached instruction manual. Figures 1-12 This invention provides an intelligent fire monitoring device for electrical systems, comprising a monitoring mounting bracket 1 and a monitoring host 2, the monitoring host 2 being mounted on the monitoring mounting bracket 1; and an active extraction detection device 3, also mounted on the monitoring mounting bracket 1, for actively extracting smoke; the active extraction detection device 3 includes a smoke hood 301, mounted on the monitoring mounting bracket 1, an exhaust fan 303 mounted on the monitoring mounting bracket 1, a follow-up smoke extraction pipe 304 connected to the exhaust fan 303, the follow-up smoke extraction pipe 304 being mounted on the smoke hood 301, and multiple smoke extraction heads 302 mounted on the smoke hood 301.

[0053] It should be noted that, in this embodiment of the invention, when the monitoring host 2 is installed in a power distribution room or power cabinet, the exhaust fan 303 is started to perform ventilation, thereby drawing the air around the power equipment into the fume hood 301 through multiple smoke extraction heads 302. Then, the air enters the transfer cover 306 through the follow-up smoke extraction pipe 304, then enters the exhaust fan 303 through the transfer cover 306, and then enters the smoke guide hood 312 through the smoke outlet hood 305, and is then delivered to the monitoring host 2. If the power equipment burns out and produces smoke, the smoke can be actively extracted so that the smoke can be detected by the monitoring host 2 more promptly, allowing for faster action to be taken. This avoids damage to the power equipment due to monitoring delays and effectively avoids monitoring blind spots caused by obstruction between different power devices.

[0054] Furthermore, in this invention, a linkage lifting device 4 is installed on the monitoring mounting bracket 1, and an active extraction detection device 3 is installed on the linkage lifting device 4. The linkage lifting device 4 is used to drive the active extraction detection device 3 to move up and down. Specifically, the linkage lifting device 4 includes a lifting drive seat 401, which is installed on the fume hood 301. A drive rotating column 402 is rotatably installed inside the lifting drive seat 401. The drive rotating column 402 is connected to the exhaust fan 303. When the exhaust fan 303 starts, it drives the drive rotating column 402 to rotate, thereby driving the lifting drive seat 401 to move up and down. It should be noted that in this embodiment of the invention, when the exhaust fan 303 is performing exhaust work, it drives the extension adapter shaft 308 to rotate, thereby causing the drive rotating column 402 to drive the fume hood 301 to move vertically up and down, achieving the purpose of fully extracting the smoke around the power equipment, and further improving the monitoring efficiency of the monitoring host 2.

[0055] More specifically, in this embodiment of the invention, an emergency fire extinguishing device 5 is installed on the active extraction detection device 3. The emergency fire extinguishing device 5 is used to extinguish fires in electrical equipment in an emergency. The emergency fire extinguishing device 5 includes four fire extinguishers 501, which are respectively installed on the top sides of the four sides of the smoke hood 301. A conversion bracket 503 is movably installed inside each of the four sides of the smoke hood 301. Multiple spray branches 504 are installed on the conversion bracket 503. The positions of the multiple spray branches 504 correspond to the positions of the multiple smoke heads 302. A spray pipe 502 is installed on the fire extinguisher 501, and the multiple spray branches 504 are all connected to the spray pipe 502. It should be noted that in this embodiment of the invention, when the monitoring host 2 monitors the power equipment, if a fire occurs on one side, the fire extinguisher 501 on the corresponding side will be automatically activated, and the fire extinguishing material will be delivered through the spray pipe 502 to multiple spray branch pipes 504, and then sprayed out through multiple smoke extraction heads 302 to achieve the function of active fire extinguishing, thereby achieving active and precise fire extinguishing and effectively protecting the safety of the power equipment.

[0056] Please refer to the instruction manual attached. Figures 3-7 Furthermore, the intelligent fire monitoring device for power provided in this embodiment of the invention, the active extraction detection device 3 also includes a transfer cover 306, the transfer cover 306 is installed on the bottom side of the exhaust fan 303, the bottom side of the exhaust fan 303 is provided with a smoke inlet 311, the smoke inlet 311 is located inside the transfer cover 306;

[0057] In addition, a smoke hood 305 is installed on the exhaust fan 303, and a smoke guide hood 312 is installed on the smoke hood 305. The position of the smoke guide hood 312 corresponds to that of the monitoring host 2. It should be noted that, in this embodiment of the invention, during monitoring, the exhaust fan 303 is started, causing the exhaust fan 303 to perform ventilation, thereby drawing the air around the electrical equipment into the smoke hood 301 through multiple smoke extraction heads 302. Then, the air enters the transfer cover 306 through the follow-up smoke extraction pipe 304, then enters the exhaust fan 303 through the transfer cover 306, and then enters the smoke guide hood 312 through the smoke hood 305, and is then delivered to the monitoring host 2. If the electrical equipment burns out and produces smoke, the smoke can be actively extracted, allowing the monitoring host 2 to detect the smoke more promptly and take measures more quickly.

[0058] More specifically, in this embodiment of the invention, an inlet filter plate 307 is installed inside the adapter hood 306, which is used to filter the flue gas. Furthermore, an extension adapter shaft 308 is installed on the output shaft of the exhaust fan 303. The extension adapter shaft 308 passes through the inlet filter plate 307, and a rotating brush strip 309 is installed on the extension adapter shaft 308. The rotation of the extension adapter shaft 308 drives the rotating brush strip 309 to rotate, thereby cleaning the inlet filter plate 307. It should be noted that in this embodiment of the invention, when the flue gas enters the adapter hood 306, it is blocked and filtered by the inlet filter plate 307, preventing impurities or foreign objects such as insects from entering the exhaust fan 303. Simultaneously, when the exhaust fan 303 starts, it synchronously drives the extension adapter shaft 308 to rotate, which in turn drives the rotating brush strip 309 to rotate, thereby filtering the inlet filter plate 307 and ensuring its filtration effect.

[0059] More specifically, in this embodiment of the invention, the fume hood 301 has multiple connecting holes 310 on all four sides, and multiple cigarette exhaust heads 302 are respectively inserted into the multiple connecting holes 310; an emergency stop switch 313 is installed on the inner wall of the bottom side of all four sides of the fume hood 301, and the emergency stop switch 313 is electrically connected to the exhaust fan 303. It should be noted that in this embodiment of the invention, when a fire occurs, causing the limiting support rod 507 on the corresponding side to soften due to heat and lose its supporting force, the conversion bracket 503 moves down to compress and trigger the emergency stop switch 313, causing the exhaust fan 303 to stop abruptly, and causing the fume hood 301 to remain at the position of the fire, achieving precise fire extinguishing and further protecting the safety of electrical equipment.

[0060] Please refer to the instruction manual attached. Figures 2-4 and Figures 8-10 Furthermore, in this embodiment of the invention, the linkage lifting device 4 also includes four guide rods 406, which are mounted on the monitoring mounting bracket 1; guide holes 408 are provided at each of the four corners of the smoke hood 301, and the four guide rods 406 are respectively movably installed in the four guide holes 408. It should be noted that in this embodiment of the invention, the smoke hood 301 slides vertically on the four guide rods 406 through the four guide holes 408, thereby achieving the purpose of vertical movement of the smoke hood 301.

[0061] More specifically, in this embodiment of the invention, a bottom bracket 407 is installed on the bottom side of two guide rods 406 located on the same side. A rotating groove 409 is provided on one bottom bracket 407, and a driving rotating column 402 is rotatably installed in the rotating groove 409. A telescopic groove 413 is provided on the inner wall of the rotating groove 409, and a wedge-shaped locking rod 414 is movably installed in the telescopic groove 413. A plurality of wedge-shaped locking slots 415 are provided in a ring at equal intervals on the driving rotating column 402, and the wedge-shaped locking rod 414 is locked in a wedge-shaped locking slot 415 at a corresponding position.

[0062] In addition, an ejector spring 416 is installed on the inner wall of the telescopic groove 413, and the ejector spring 416 is mounted on the wedge-shaped locking rod 414. It should be noted that, in this embodiment of the invention, when the drive rotating column 402 rotates, it rotates within the rotating groove 409. Simultaneously, the drive rotating column 402 rotates and squeezes the wedge-shaped locking rod 414 through the wedge-shaped locking groove 415, causing the wedge-shaped locking rod 414 to be squeezed and retracted into the telescopic groove 413. At the same time, it drives the ejector spring 416 to retract. When the wedge-shaped locking rod 414 rotates to the next wedge-shaped locking groove 415, under the rebound force of the ejector spring 416, the wedge-shaped locking rod 414 is inserted into the wedge-shaped locking groove 415, and the drive rotating column 402 repeats this action while rotating. In the event of a fire, when the exhaust fan 303 stops suddenly, the wedge-shaped locking rod 414 can be inserted into the corresponding wedge-shaped locking groove 415, thereby stopping the smoke hood 301 in that position, which can effectively and continuously extinguish the fire at that position.

[0063] Please continue to refer to the instruction manual appendix. Figures 2-4 and Figures 8-10 More specifically, in this embodiment of the invention, the lifting drive seat 401 has a rotating hole 403, and the driving rotating column 402 is rotatably installed in the rotating hole 403; the driving rotating column 402 has a driving ring groove 404, and a driving block 405 is installed on the inner wall of the rotating hole 403, extending into the driving ring groove 404. It should be noted that in this embodiment of the invention, when the driving rotating column 402 rotates, it rotates within the rotating hole 403. Simultaneously, the rotation of the driving rotating column 402 drives the driving block 405 to move through the driving ring groove 404. The movement of the driving block 405 drives the lifting drive seat 401 to move, thereby achieving the purpose of the lifting drive seat 401 moving to move the fume hood 301.

[0064] More specifically, in this embodiment of the invention, a connecting rotating shaft 411 is rotatably mounted on the connecting cover 306, and the connecting rotating shaft 411 is mounted on the driving rotating column 402; in addition, a driving gear 410 is mounted on the extending connecting shaft 308, and an amplifying gear 412 is mounted on the connecting rotating shaft 411, with the driving gear 410 and the amplifying gear 412 meshing. It should be noted that, in this embodiment of the invention, when the extending connecting shaft 308 rotates, it drives the driving gear 410 to rotate, which in turn drives the amplifying gear 412 to rotate. The rotation of the amplifying gear 412 drives the driving rotating column 402 to rotate via the connecting rotating shaft 411. The rotation of the driving rotating column 402 drives the lifting driving seat 401 to move, and the movement of the lifting driving seat 401 drives the smoke hood 301 to move, thereby realizing the lifting and lowering of the smoke hood 301.

[0065] Please refer to the instruction manual attached. Figures 3-4 and Figures 11-12 Furthermore, the intelligent fire monitoring device for electricity provided in this embodiment of the invention includes an emergency fire extinguishing device 5 that further comprises multiple limiting support rods 507. Each of the four sides of the smoke hood 301 has two pull-down holes 509, and pull-down brackets 506 are movably installed in the two pull-down holes 509 on the same side. A conversion bracket 503 is installed on the two pull-down brackets 506, and the limiting support rods 507 are inserted into the smoke hood 301 and the pull-down brackets 506. It should be noted that in this embodiment of the invention, when a fire occurs, the limiting support rods 507 on the corresponding side soften due to heat and lose their supporting force, thereby causing the conversion bracket 503 to move downwards. At this time, the positions of multiple spray branches 504 correspond to the positions of multiple smoke extraction heads 302. Simultaneously, the downward movement of the conversion bracket 503 presses down the squeeze handle 505. The fire extinguisher 501 then delivers the extinguishing material through the spray pipe 502 into the multiple spray branches 504, and then sprays it out through the multiple smoke extraction heads 302, achieving the function of active fire extinguishing.

[0066] More specifically, in this embodiment of the invention, a squeeze handle 505 is installed on the bottom side of the fire extinguisher 501, and the conversion bracket 503 moves downward to squeeze the squeeze handle 505; in addition, two pull-down springs 508 are installed on the top side of the conversion bracket 503, and the two pull-down springs 508 are installed on the inner wall of the smoke hood 301. It should be noted that, in this embodiment of the invention, when a fire occurs, the contraction force of the two pull-down springs 508 causes the conversion bracket 503 to move downward, and the conversion bracket 503 moves downward to press down the squeeze handle 505. At this time, the fire extinguisher 501 delivers the extinguishing material through the spray pipe 502 to multiple spray branch pipes 504, and then sprays it out through multiple smoke hoods 302, realizing the function of active fire extinguishing.

[0067] In summary, the working principle of the intelligent power fire monitoring device provided in this embodiment of the invention is as follows:

[0068] When the monitoring host 2 is installed in the power distribution room or power cabinet, the monitoring mounting bracket 1 and the bottom bracket 407 are installed inside it, and then the monitoring host 2 is installed on the monitoring mounting bracket 1. When the monitoring host 2 monitors the power equipment in the power distribution room or power cabinet, it analyzes the smoke or accurately identifies the electric arc through intelligent algorithms, making the fire monitoring of power equipment more intelligent.

[0069] Furthermore, during monitoring, the exhaust fan 303 is activated to perform ventilation, thereby drawing the air around the electrical equipment into the fume hood 301 through multiple smoke extraction heads 302. The air then enters the transfer cover 306 through the follow-up smoke extraction pipe 304, then enters the exhaust fan 303 through the transfer cover 306, and finally enters the smoke guide hood 312 through the smoke outlet hood 305, before being delivered to the monitoring host 2. It should be noted that if electrical equipment burns out and generates smoke, the smoke can be actively extracted, allowing the monitoring host 2 to detect it more promptly and take action more quickly. This avoids damage to the electrical equipment due to monitoring delays and effectively prevents monitoring blind spots caused by obstructions between electrical devices. Furthermore, when the smoke enters the adapter hood 306, it is filtered by the smoke inlet filter plate 307, preventing impurities or foreign objects such as insects from entering the exhaust fan 303. In addition, when the exhaust fan 303 starts, it simultaneously drives the extension adapter shaft 308 to rotate, which in turn drives the rotating brush strip 309 to rotate, thereby filtering the smoke inlet filter plate 307 and ensuring its filtration effect.

[0070] It should be further explained that when the extension adapter shaft 308 rotates, it drives the drive gear 410 to rotate, which in turn drives the amplification gear 412 to rotate. The rotation of the amplification gear 412 drives the drive rotating column 402 to rotate via the adapter rotating shaft 411. The drive rotating column 402 rotates within the rotating hole 403. When the drive rotating column 402 rotates, it drives the drive block 405 to move via the drive ring groove 404. The movement of the drive block 405 drives the lifting drive seat 401 to move. The movement of the lifting drive seat 401 drives the smoke hood 301 to move. The smoke hood 301 slides vertically on the four guide rods 406 through the four guide holes 408. When the drive rotating column 402 rotates one revolution, the drive smoke hood 301 moves vertically up and down once, thereby achieving the purpose of fully extracting the smoke around the power equipment and further improving the monitoring efficiency of the monitoring host 2.

[0071] Furthermore, when the drive rotating column 402 rotates, it rotates within the rotating groove 409. Simultaneously, the drive rotating column 402 rotates and squeezes the wedge-shaped clamp 414 through the wedge-shaped clamp groove 415, causing the wedge-shaped clamp 414 to be squeezed and retracted into the telescopic groove 413, while simultaneously driving the ejector spring 416 to retract. It should be noted that when the wedge-shaped lever 414 rotates to the next wedge-shaped slot 415, the rebound force of the ejector spring 416 causes the wedge-shaped lever 414 to insert into the wedge-shaped slot 415, causing the drive rotating column 402 to repeat this action while rotating. In the event of a fire, when the exhaust fan 303 stops suddenly, the wedge-shaped lever 414 can be inserted into the corresponding wedge-shaped slot 415, causing the smoke hood 301 to stop at that position, allowing for effective and continuous fire extinguishing at that location, thus ensuring the safety of the electrical equipment. In addition, the amplifying gear 412, when the drive gear 410 rotates multiple times, drives the amplifying gear 412 to rotate one revolution, thereby causing the smoke hood 301 to move vertically once. This reduces the speed of the smoke hood 301 during vertical lifting and lowering, ensuring effective extraction of air around the electrical equipment and improving the accuracy of the monitoring host 2 in detecting smoke.

[0072] Furthermore, when the monitoring host 2 monitors the power equipment, if a fire occurs on one side, the limiting support rod 507 on the corresponding side softens due to heat and loses its supporting force. At this time, under the contraction force of the two pull-down springs 508, the conversion bracket 503 moves down. At this time, the positions of multiple spray branch pipes 504 and multiple smoke extraction heads 302 correspond. Simultaneously, the conversion bracket 503 moves down and presses down the squeeze handle 505. At this time, the fire extinguisher 501 delivers the extinguishing material through the spray pipe 502 to the multiple spray branch pipes 504, and then sprays it out through the multiple smoke extraction heads 302, realizing the function of active fire extinguishing. In addition, the downward movement of the conversion bracket 503 squeezes and triggers the emergency stop switch 313, causing the exhaust fan 303 to stop suddenly and the smoke extraction hood 301 to stay at the position of the fire, realizing precise fire extinguishing and further protecting the safety of the power equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
