[0034] A further improvement of the technical solution of the present invention is as follows: a lower annular groove is provided on the annular seat; the lower rotating ring is rotatably embedded in the lower annular groove through an annular bearing disc or roller; a lower annular air inlet slot is provided on one side of the lower rotating ring; the lower annular air inlet slot is connected to the hollow rod; sealing sliding washers are respectively provided above and below the lower annular air inlet slot; the sealing sliding washers, the lower rotating ring, and the inner wall of the lower annular groove form a lower sealed air inlet cavity; the lower annular air inlet slot and the air outlet pipe of the fire extinguishing pump are respectively connected to the lower sealed air inlet cavity; a first solenoid valve is provided on the air outlet pipe of the fire extinguishing pump; a straight tooth forming a gear ring is provided on the inner wall of the lower rotating ring above or below the lower sealed air inlet cavity, and a first motor meshes with the gear ring through a gear system. The upper rotating ring is driven to rotate; an upper annular groove is provided on the upper body; the upper rotating ring is rotatably embedded in the upper annular groove through an annular bearing disc or roller; an upper annular air inlet slot is provided on one side of the upper rotating ring; the upper annular air inlet slot is connected to the hollow rod body; sealing sliding washers are respectively provided above and below the upper annular air inlet slot; the sealing sliding washers, the upper rotating ring, and the inner wall of the upper annular groove form an upper sealed air inlet cavity; the upper annular air inlet slot and the air outlet pipe of the heat pump are respectively connected to the upper sealed air inlet cavity; a second solenoid valve is provided on the air outlet pipe of the heat pump; above or below the upper sealed air inlet cavity, a straight tooth forming a gear ring is provided on the inner wall of the upper rotating ring, and a second motor drives the upper rotating ring to rotate through a gear system meshing with the gear ring.

[0035] The protection method of the protection device includes the following steps:

[0036] ① Under normal conditions, the hollow rod body is tilted at a certain angle, and the first motor and the second motor drive the lower rotating ring and the upper rotating ring to rotate at the same speed; thereby driving the hollow rod body as a whole to rotate around the power outage treatment terminal;

[0037] ② During the rotation, the second solenoid valve opens; the cooling pump draws in air from the outside and pumps compressed air into the hollow rod from the top. The compressed air is further compressed inside the hollow rod and sprayed out through the air outlet slit. The sprayed compressed air expands and cools down, blowing on the power outage treatment terminal to help it dissipate heat.

[0038] ③ When the fire alarm system detects a fire in the power outage management terminal or computer room, it controls the cooling pump to stop working and closes the second solenoid valve; it controls the fire extinguishing pump to work and opens the first solenoid valve; the fire extinguishing pump extracts compressed carbon dioxide from the sealed cavity in the pit and pumps compressed carbon dioxide into it from the lower end of the hollow rod. The carbon dioxide is further compressed in the hollow rod and sprayed out through the air outlet slit. The sprayed compressed carbon dioxide expands and cools down, blowing on the power outage management terminal to help cool it down and extinguish the fire.

[0039] ④ As the carbon dioxide in the sealed cavity of the pit is extracted, the carbon dioxide pressure decreases, making it unable to support the weight of the power outage control terminal. The piston seat, carrying the power outage control terminal, gradually descends into the pit. After the piston seat descends past the upper solid part, the upper and lower parts of the piston seat are connected by the airflow channel enclosed by the inner and outer cylinders. The carbon dioxide in the pit flows upward through the airflow channel through the through hole of the inner cylinder and is sprayed out again through the through hole of the inner cylinder to blow on the surface of the power outage control terminal to further help cool it down and extinguish the fire. Because the carbon dioxide in the pit increases the escape channels, the carbon dioxide escapes faster, and the descent of the power outage control terminal accelerates.

[0040] ⑤ When the power outage control terminal descends to its final stage, the insulation board fixed at the top and the upper solid part are sealed and nested. At this time, the fire extinguishing pump is still pumping air outward, and the air pressure in the pit is further reduced to below the outside atmospheric pressure. Under the action of the outside atmospheric pressure, the insulation board and the upper solid part are tightly squeezed, so that a sealed space is formed in the pit again. At this time, the fire extinguishing pump continues to pump air outward, which is called vacuuming. The vacuuming process takes away the oxygen present in the sealed space and the power outage control terminal. Without the oxidizing agent, any possible fire on or inside the power outage control terminal is quickly extinguished. At this time, the power outage control terminal is sealed in the pit, and any possible fire in the external machine room is isolated from the outside.

[0041] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0042] 1. The power outage management terminal of the present invention utilizes the cooperation between the connecting sleeve, top plate, tightening spring, toothed plate, drive wheel, threaded rod, threaded slider, connecting rod, and protective baffle. The tightening spring actuates the top plate, which in turn drives the drive wheel to rotate via the toothed plate. The threaded rod then drives the threaded slider to move, which in turn drives the protective baffle to rotate via the connecting rod. This protective baffle is positioned inside the connecting sleeve to protect the interface, preventing dust corrosion and avoiding poor contact at the interface.

[0043] 2. The power outage management terminal of this invention utilizes the cooperation between a heat dissipation box, a heat-absorbing copper plate, heat dissipation fins, a heat dissipation chamber, a dustproof net, a fan, and a semiconductor cooling chip. The heat-absorbing copper plate absorbs heat from inside the equipment, the heat dissipation fins dissipate the absorbed heat, and the fan circulates air in the heat dissipation chamber, improving heat dissipation. The semiconductor cooling chip further enhances the heat dissipation effect, facilitating equipment use and preventing damage.

[0044] 3. The power outage management terminal of this invention, through the cooperation of a drive rod, a drive wheel, a driven wheel, a rotating rod, a cam, a lifting plate, a support leg, and a moving wheel, allows the equipment to be moved easily when needed. Rotating the drive rod drives the drive wheel, which in turn drives the rotating rod. The cam then actuates the lifting plate, causing the support leg to extend. The moving wheel facilitates the movement of the equipment, making its use more convenient and avoiding any limitations on its operation.

[0045] 4. The protection device of this invention uses a hollow rod rotating around the power outage management terminal to pressurize and circulate external air to the terminal. This works in conjunction with the heat sink and heat dissipation shell on the terminal's surface to help cool it down, thereby ensuring the operational stability and efficiency of the power outage management terminal. The air outlet slits on the hollow rod allow the pressurized air to expand, depressurize, and cool down as it exits, resulting in a lower airflow temperature that effectively assists in cooling the power outage management terminal. Furthermore, the pumped air is drawn in from the upper body, which is suspended above the power outage management terminal, preventing the intake of ground dust. The hollow rod rotates at an angle, and combined with the air outlet slits extending along its length, it achieves a combined effect of posture, rotation, and airflow. The airflow has a cyclone effect, allowing the air to exchange heat with the power outage treatment terminal while spreading downwards and outwards. This effectively removes heat from the bottom, preventing it from escaping upwards and being re-drawn in by the cooling pump, thus ensuring effective heat dissipation during long-term operation. It also employs a rotating ring, annular air inlet slot, and sealing sliding gasket design, ensuring that the continuous and stable airflow is not affected during the rotation of the rotating ring. Furthermore, it is equipped with a corrugated expansion tube. By controlling the speed and speed difference between the first and second motors, combined with the corrugated expansion tube, the tilt angle and direction of the hollow rod can be easily controlled, even during operation, allowing for continuous and unimpeded adjustment, thereby enabling the control and variation of the generated airflow.

[0046] 5. The protective device of this invention utilizes pits and piston seats, and pressurized carbon dioxide as support, thus placing the power outage management terminal in a state of suspension. This effectively buffers vibrations of various degrees, especially minute vibrations, preventing the long-term adverse effects of imperceptible minor vibrations from the surrounding environment on the power outage management terminal. It also provides excellent earthquake-resistant buffering for larger vibrations such as earthquakes. Furthermore, the pressurized carbon dioxide, acting as support, suspension, and buffer, also functions as a fire extinguisher and elevator in a cleverly designed manner. When the fire alarm system detects a power outage at the power outage management terminal 1 or the machine room... In the event of a fire, compressed carbon dioxide is extracted from the sealed cavity by a fire pump and sprayed onto the power outage control terminal using a hollow rod. Simultaneously, the pressure in the sealed cavity decreases due to the release of carbon dioxide, making it unable to support the weight of the power outage control terminal. The piston seat, carrying the terminal, gradually descends into the pit. Once the piston seat has passed the upper solid section, the upper and lower parts of the piston seat are connected by an airflow channel formed by the inner and outer cylinders. Carbon dioxide in the pit flows upward through the airflow channel via the through-holes in the inner cylinder and is then sprayed out again through the through-holes in the inner cylinder to further cool the surface of the power outage control terminal. On the one hand, the fire extinguishing mechanism facilitates fire suppression; on the other hand, the increased carbon dioxide in the pit increases the escape routes, thus accelerating the escape of carbon dioxide and accelerating the descent of the power outage control terminal, acting as an elevator to automatically, quickly, and smoothly lower the power outage control terminal into the pit. When the power outage control terminal reaches its final descent, the insulation board fixed at its top seals and nests with the upper solid part. At this time, the fire extinguishing pump is still pumping air outward, further reducing the air pressure in the pit to below the outside atmospheric pressure. Under the action of the outside atmospheric pressure, the insulation board and the upper solid part are tightly compressed, creating a sealed space in the pit again. At this time, the fire extinguishing pump continues to pump air outward, which is called vacuuming. The vacuuming process... The oxygen present in the sealed space and the power outage management terminal is removed, and without the oxidizing agent, any potential fire on or inside the power outage management terminal is quickly extinguished. At this time, the power outage management terminal is sealed in the pit, and any potential fire in the external computer room is isolated. Therefore, the protection device of this system, through its ingenious design, enables the hollow rod, carbon dioxide, pit, etc., to perform multiple effective functions simultaneously or automatically in sequence. The functions of each component are closely integrated and interact with each other, thereby effectively protecting the power outage management terminal in the event of a fire in the power outage management terminal itself or in the computer room where it is located, avoiding hardware and data loss.

[0063] The present invention will be further described in detail below with reference to embodiments:

[0064] Example 1

[0065] Firstly, such as Figure 1-7As shown, this invention provides a support system for managing frequent power outages in low-voltage meter boxes, including a power outage management terminal 1. A display screen 11 is installed at the front end of the power outage management terminal 1. A data interface 2 is fixedly connected to the top right side of the power outage management terminal 1. A heat dissipation mechanism 3 is fixedly connected to the middle right side of the power outage management terminal 1. A moving mechanism 4 is installed at the bottom right end of the power outage management terminal 1. The data interface 2 includes a connecting sleeve 21, which is fixedly connected to the top right side of the power outage management terminal 1. A top plate 2 is movably connected to the inner side of the connecting sleeve 21. 2. A top plate 22 is fixedly connected to a top tensioning spring 23. A toothed plate 24 is fixedly connected to the inside of the top plate 22. A drive wheel 25 is movably connected to the side of the toothed plate 24. A threaded rod 26 is fixedly connected to the left side of the drive wheel 25. The threaded rod 26 is movably connected to the inside of the connecting sleeve 21. A threaded slider 27 is threadedly connected to the side of the threaded rod 26. A connecting rod 28 is movably connected to the side of the threaded slider 27. A protective baffle 29 is movably connected to one end of the connecting rod 28. The protective baffle 29 is movably connected to the inside of the connecting sleeve 21.

[0066] In this embodiment, when the power outage management terminal 1 is in use, the moving mechanism 4 facilitates its movement. The protective baffle 29, which is placed inside the connecting sleeve 21, protects the data interface 2. During use, by pushing the top plate 22 and pressing the clamping spring 23, the toothed plate 24 drives the drive wheel 25 to rotate, and the threaded rod 26 drives the threaded slider 27 to move. This allows the connecting rod 28 to open the protective baffle 29, enabling the connection of the data transmission line for data transmission. This facilitates the analysis of power distribution faults and the maintenance of the lines. During use, the heat dissipation mechanism 3 can also dissipate heat from the equipment, preventing damage caused by prolonged use.

[0067] Example 2

[0068] like Figure 1-7 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the protective baffle 29 includes a rotating baffle 291, the rotating baffle 291 is movably connected to the inner side of the connecting sleeve 21, a protective pad 292 is fixedly connected to the side of the rotating baffle 291, a telescopic pad 293 is fixedly connected to the middle of the protective pad 292, a push spring 294 is provided inside the rotating baffle 291, a push rod 295 is fixedly connected to the bottom end of the push spring 294, and the bottom end of the push rod 295 is fixedly connected to the inner side of the protective pad 292.

[0069] In this embodiment, when the connecting sleeve 21 is protected by the protective baffle 29, as the rotating baffle 291 rotates, the push spring 294 pushes the push rod 295, and drives the telescopic pad 293 to extend and retract. Thus, the upper and lower rotating baffles 291 can be pressed together by the protective pad 292, avoiding gaps between the rotating baffles 291, and making the protection effect on the connecting sleeve 21 better.

[0070] Example 3

[0071] like Figure 1-7 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the heat dissipation mechanism 3 includes a heat dissipation box 31, which is fixedly connected to the side of the power outage management terminal 1. A heat-absorbing copper plate 32 is fixedly connected to the left side of the heat dissipation box 31, and a heat dissipation fin 33 is fixedly connected to the right side of the heat-absorbing copper plate 32. A heat dissipation chamber 34 is opened inside the heat dissipation box 31. A dustproof net 35 is fixedly connected to the side of the heat dissipation box 31. A fan 36 is fixedly connected to the left side of the dustproof net 35. A semiconductor cooling chip 37 is fixedly connected to the left side of the heat-absorbing copper plate 32, and one end of the semiconductor cooling chip 37 extends into the interior of the heat dissipation chamber 34.

[0072] In this embodiment, when the device is used for a long time, the heat-absorbing copper plate 32 can absorb the heat inside the device, and the heat dissipation fins 33 can dissipate the absorbed heat, thereby cooling the device. The fan 36 allows the air to circulate in the heat dissipation chamber 34 under the filtration of the dust filter 35, which improves the heat dissipation effect. The semiconductor cooling chip 37 enables heat exchange between the inside of the device and the inside of the heat dissipation chamber 34, which improves the heat dissipation effect and prevents damage to the device.

[0073] Example 4

[0074] like Figure 1-7As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the moving mechanism 4 includes a drive rod 41, which is movably connected to the side of the power outage management terminal 1. One end of the drive rod 41 is fixedly connected to a drive wheel 42, which is movably connected inside the power outage management terminal 1. A driven wheel 43 is meshed with the side of the drive wheel 42, and a rotating rod 44 is fixedly connected to the side of the driven wheel 43. A cam 45 is fixedly connected to the side of the rotating rod 44, and a lifting plate 46 is provided on the side of the cam 45. The lifting plate 46 is movably connected inside the power outage management terminal 1, and the bottom end of the lifting plate 46 is fixedly connected to the drive rod 43. A support leg 47 is fixedly connected, and a movable wheel 48 is movably connected to the bottom end of the support leg 47. The support leg 47 includes a support column 471, which is located at the bottom end of the lifting plate 46. A fixing spring 472 is installed inside the support column 471.

The pull plate 474 is fixedly connected to the bottom end of the lifting plate 46. A sliding groove 475 is opened inside the fixing block 473. A sliding block 476 is movably connected inside the sliding groove 475. The sliding block 476 is fixedly connected inside the pull plate 474.

[0075] In this embodiment, when the equipment needs to be used, the drive rod 41 is rotated, which drives the drive wheel 42 to rotate. The driven wheel 43 drives the rotating rod 44 to rotate, which in turn drives the cam 45 to push the lifting plate 46, thereby causing the support leg 47 to extend from the bottom of the power outage management terminal 1. The fixing spring 472 pushes the fixing block 473, which can be locked into the interior of the power outage management terminal 1, thereby fixing the support leg 47. The moving wheel 48 facilitates the movement of the equipment, making the equipment more convenient to use. At the same time, the return of the lifting plate 46 will pull the pull plate 474, and the sliding block 476 can slide in the sliding groove 475 to pull back the fixing block 473, which facilitates the retraction of the moving wheel 48.

[0077] Secondly, such as Figure 1-7 As shown, the present invention also provides a method for managing and supporting frequent power outages in low-voltage meter boxes, which includes the following steps:

[0078] Step 1: User Data Collection;

[0079] Step 2: Fault model matching;

[0080] Step 3: Link user information;

[0081] Step 4: Categorize faulty users;

[0082] Step 5: Troubleshooting and repair.

[0083] Step two also includes the following steps:

[0084] A1: Determine the fault model based on user electricity consumption data;

[0085] A2: Based on the user's electricity consumption data, match it with the defined fault model to generate the first fault user list;

[0086] A3: Analyze the faulty users in the first faulty user list and fit the faulty user's electricity consumption data to the fault model matching degree, thereby generating the second faulty user list.

[0087] Step three also includes the following steps:

[0088] B1: Associate the fault information in the second fault user list to generate a fault user information list;

[0089] B2: Analyze all faulty users in the faulty user information list using a backtracking algorithm;

[0090] B3: Obtain the list of faulty users under different transformer substations to identify the faults.

[0091] Step five also includes the following steps:

[0092] C1: Generate corresponding work orders from the categorized list of faulty users;

[0093] C2: Notify maintenance personnel to refer to the generated work order and handle the fault promptly.

[0094] In this embodiment, when the low-voltage meter box experiences frequent power outages due to circuit faults, user information is collected and matched with fault models to generate a first list of faulty users. This is then matched again to generate a second list of faulty users. Furthermore, by associating fault information, a list of faulty user information is generated. Through a backtracking algorithm, the faulty users are easily identified, facilitating the handling by maintenance personnel.

[0095] Example 6

[0096] like Figure 8-15As shown, in addition, since the power outage management terminal 1 is very important and stores a large amount of important data, in order to improve the security of the power outage management terminal 1, especially in the event of fires or other situations that may occur in servers and computer rooms, this application also specifically designs a protective device for protecting the power outage management terminal 1. The protective device includes a pit 51 that is vertically sunken into the ground, an annular base 52 fixed to the ground and arranged around the pit 51, and an upper body 53 fixedly arranged above the power outage management terminal 1 corresponding to the annular base 52; a lower rotating ring 521 is provided on the annular base 52; an upper rotating ring 531 is provided on the upper body 53 corresponding to the lower rotating ring 521; one or more hollow rods 54 are connected between the lower rotating ring 521 and the upper rotating ring 531; The hollow rod 54 has an air outlet slit along its length on the side facing the power outage management terminal 1; a cooling pump 55 pumps air in through the upper end of the hollow rod 54 (which can be opened and closed) and blows it out under pressure through the air outlet slit for heat dissipation; a fire extinguishing pump 56 pumps carbon dioxide in through the lower end of the hollow rod 54 (which can be opened and closed) and blows it out under pressure through the air outlet slit for fire extinguishing; a piston seat 58 is installed at the bottom of the power outage management terminal 1 and an insulation plate 59 is installed at the top; the piston seat 58 is in a sealed sliding fit with the upper part of the inner wall of the pit 51, and the sealed cavity formed by the piston seat 58 and the pit 51 is filled with carbon dioxide under pressure to support the power outage management terminal 1; an exhaust pipe 511 is provided at the bottom of the pit 51; the exhaust pipe 511 is connected to the air inlet of the fire extinguishing pump 56; the insulation plate 59 can be sealed and nested with the upper part of the inner wall of the pit 51.

[0097] In this embodiment, the inner wall of the pit 51 includes an upper solid portion 512 and a lower double-layer portion; the upper solid portion 512 has an inclined surface at its upper part and a vertical surface at its lower part; the piston seat 58 is in a sealing sliding fit with the vertical surface, and the upper solid portion 512 has a protruding protrusion 515 at its upper part; the protrusion 515 interferes with the piston seat 58 to prevent the piston seat 58 from being squeezed out of the pit 51; the inner diameter of the inclined surface gradually decreases from top to bottom until it is the same as the inner diameter of the vertical surface; the lower double-layer portion includes an inner cylinder 513 with multiple through holes and a solid outer cylinder 514; the inner diameter of the inner cylinder 513 is the same as the inner diameter of the vertical surface of the upper solid portion 512. The inner cylinder 513 and outer cylinder 514 are connected in a smooth transition; the distance between them is set to enclose an airflow channel; when the piston seat 58 sinks over the upper solid part 512, the carbon dioxide in the pit 51 flows upward through the through hole of the inner cylinder 513, through the airflow channel, and is sprayed out again through the through hole of the inner cylinder 513 to blow on the surface of the power outage management terminal 1; the outer circumferential surface of the insulation plate 59 has an inclined surface corresponding to the inclined surface of the upper solid part 512, so that the insulation plate 59 can be sealed and nested with the upper solid part 512 at the end of the sinking of the power outage management terminal 1; the two ends of the hollow rod 54 are respectively connected to the corrugated expansion and deformation tubes 542.

[0098] In this embodiment, a lower annular groove 524 is provided on the annular seat 52; a lower rotating ring 521 is rotatably embedded in the lower annular groove 524 via an annular bearing disc or roller; a lower annular air inlet slot 522 is provided on one side of the lower rotating ring 521; the lower annular air inlet slot 522 is connected to the hollow rod 54; sealing sliding washers 523 are respectively provided above and below the lower annular air inlet slot 522; the sealing sliding washers 523, the lower rotating ring 521, and the inner wall of the lower annular groove 524 form a lower sealed air inlet cavity; the lower annular air inlet slot 522 and the air outlet pipe of the fire extinguishing pump 56 are respectively connected to the lower sealed air inlet cavity; a first solenoid valve 561 is provided on the air outlet pipe of the fire extinguishing pump 56; above or below the lower sealed air inlet cavity, a straight toothed gear ring is provided on the inner wall of the lower rotating ring 521, and a first motor 525 drives the lower rotating ring 52 through a gear system meshing with the gear ring. 1. Rotation; An upper annular groove 534 is provided on the upper body 53; An upper rotating ring 531 is rotatably embedded in the upper annular groove 534 through an annular bearing disc or roller; An upper annular air inlet slot 532 is provided on one side of the upper rotating ring 531; The upper annular air inlet slot 532 is connected to the hollow rod body 54; Sealing sliding washers 523 are respectively provided above and below the upper annular air inlet slot 532; The sealing sliding washers 523, the upper rotating ring 531, and the inner wall of the upper annular groove 534 form an upper sealed air inlet cavity; The upper annular air inlet slot 522 and the air outlet pipe of the heat pump 55 are respectively connected to the upper sealed air inlet cavity; A second solenoid valve 551 is provided on the air outlet pipe of the heat pump 55; Above or below the upper sealed air inlet cavity, a straight tooth forming a gear ring is provided on the inner wall of the upper rotating ring 531, and a second motor 535 drives the upper rotating ring 531 to rotate through a gear system meshing with the gear ring.

[0099] In this embodiment, the protection method of the protection device includes the following steps:

[0100] ①For example Figure 8 As shown, under normal conditions, the hollow rod 54 is tilted at a certain angle, and the first motor 525 and the second motor 535 drive the lower rotating ring 521 and the upper rotating ring 531 to rotate at the same speed; thereby driving the hollow rod 54 to rotate around the power outage management terminal 1 as a whole.

[0101] ② During the rotation process, the second solenoid valve 551 is opened; the cooling pump 55 draws in air from the outside and pumps compressed air into the hollow rod 54 from the top end. The compressed air is further compressed inside the hollow rod 54 and sprayed out through the air outlet slit. The sprayed compressed air expands and cools down, blowing on the power outage treatment terminal 1 to help it dissipate heat.

[0102] ③ When the fire alarm system detects a fire in the power outage management terminal 1 or the computer room, it controls the cooling pump 55 to stop working and the second solenoid valve 551 to close; it controls the fire extinguishing pump 56 to work and the first solenoid valve 561 to open; the fire extinguishing pump 56 extracts compressed carbon dioxide from the sealed cavity in the pit 51 and pumps compressed carbon dioxide into the hollow rod 54 from the lower end of the hollow rod 54. The carbon dioxide is further compressed in the hollow rod 54 and sprayed out through the air outlet slit. The sprayed compressed carbon dioxide expands and cools down, blowing on the power outage management terminal 1 to help cool it down and extinguish the fire.

[0103] ④ For example Figure 9 As shown, as the carbon dioxide in the sealed cavity of the pit 51 is extracted, the carbon dioxide pressure decreases, making it unable to support the weight of the power outage control terminal 1. The piston seat 58, carrying the power outage control terminal 1, gradually descends into the pit 51. After the piston seat 58 descends past the upper solid part 512, the piston seat 58 is connected vertically through the airflow channel enclosed by the inner cylinder 513 and the outer cylinder 514. The carbon dioxide in the pit 51 flows upward through the airflow channel through the through hole of the inner cylinder 513 and is sprayed out again through the through hole of the inner cylinder 513 to blow on the surface of the power outage control terminal 1 to further help cool it down and extinguish the fire. Because the carbon dioxide in the pit 51 has increased escape channels, the carbon dioxide escapes faster, and the descent of the power outage control terminal 1 accelerates.

[0104] ⑤ For example Figure 10 As shown, when the power outage management terminal 1 descends to its final stage, the insulation plate 59 fixed at its top and the upper solid part 512 are sealed and nested together. At this time, the fire extinguishing pump 56 is still pumping air outward, and the air pressure in the pit 51 is further reduced to below the external atmospheric pressure. Under the action of the external atmospheric pressure, the insulation plate 59 and the upper solid part 512 are tightly squeezed together, so that a sealed space is formed again in the pit 51. At this time, the fire extinguishing pump 56 continues to pump air outward, which is called vacuuming. The vacuuming process takes away the oxygen present in the sealed space and in the power outage management terminal 1. Without the oxidizing agent, any possible fire on or inside the power outage management terminal 1 is quickly extinguished. At this time, the power outage management terminal 1 is sealed in the pit 51, and any possible fire in the external machine room is isolated from the outside.

[0105] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

8. The support system for managing frequent power outages in low-voltage meter boxes according to claim 7, characterized in that: The protection method of the protection device includes the following steps: ① Under normal conditions, the hollow rod (54) is tilted at a certain angle, and the first motor (525) and the second motor (535) drive the lower rotating ring (521) and the upper rotating ring (531) to rotate at the same speed; thereby driving the hollow rod (54) to rotate around the power outage management terminal (1) as a whole. ② During the rotation process, the second solenoid valve (551) is opened; the cooling pump (55) draws in air from the outside and pumps compressed air into the hollow rod (54) from the top end. The compressed air is further compressed inside the hollow rod (54) and sprayed out through the air outlet slit. The sprayed compressed air expands and cools down, blowing on the power outage treatment terminal (1) to help it dissipate heat. ③ When the fire alarm system detects a fire in the power outage management terminal (1) or the computer room, it controls the cooling pump (55) to stop working and the second solenoid valve (551) to close; it controls the fire extinguishing pump (56) to work and the first solenoid valve (561) to open; the fire extinguishing pump (56) extracts compressed carbon dioxide from the sealed cavity in the pit (51) and pumps compressed carbon dioxide into it from the lower end of the hollow rod (54). The carbon dioxide is further compressed in the hollow rod (54) and sprayed out through the air outlet slit. The sprayed compressed carbon dioxide expands and cools down, blowing on the power outage management terminal (1) to help it cool down and extinguish the fire. ④ As the carbon dioxide in the sealed cavity of the pit (51) is extracted, the carbon dioxide pressure decreases and can no longer support the weight of the power outage control terminal (1). The piston seat (58) carries the power outage control terminal (1) and gradually descends into the pit (51). After the piston seat (58) descends past the upper solid part (512), the piston seat (58) is connected to the upper and lower parts through the airflow channel enclosed by the inner cylinder (513) and the outer cylinder (514). The carbon dioxide in the pit (51) flows upward through the airflow channel through the through hole of the inner cylinder (513) and is sprayed out again through the through hole of the inner cylinder (513) to blow on the surface of the power outage control terminal (1) to further help it cool down and extinguish the fire. Since the carbon dioxide in the pit (51) increases the escape channel, the carbon dioxide escapes faster and the descent of the power outage control terminal (1) accelerates. ⑤ When the power outage management terminal (1) descends to its final stage, the insulation board (59) fixed on its top and the upper solid part (512) are sealed and nested. At this time, the fire extinguishing pump (56) is still pumping air outward, and the air pressure in the pit (51) is further reduced to below the outside atmospheric pressure. Under the action of the outside atmospheric pressure, the insulation board (59) and the upper solid part (512) are tightly squeezed, so that a sealed space is formed in the pit (51) again. At this time, the fire extinguishing pump (56) continues to pump air outward, which is called vacuuming. The vacuuming process takes away the oxygen in the sealed space and the power outage management terminal (1). Without the oxidizing agent, the fire on or inside the power outage management terminal (1) is quickly extinguished. At this time, the power outage management terminal (1) is sealed in the pit (51), and the fire in the external machine room is isolated from the outside.
