Description

Technical Field

[0001] The present invention belongs to the technical field of power equipment, and particularly relates to a box-type power control cabinet. Background Art

[0002] The integrated cabin of box-type transformer and PCS is a comprehensive power equipment, which integrates a variety of devices such as a power conversion system (PCS), a step-up transformer, a high-voltage ring main unit, and a low-voltage distribution box in a container or combines them into one. In the traditional energy storage system, two voltage conversions are usually required during the conversion process, while the integrated PCS and step-up unit can combine these two processes into one, thereby reducing the loss of converted energy and improving the efficiency of the system.

[0003] The integrated cabin of box-type transformer and PCS also has some disadvantages. The following is a detailed analysis of its disadvantages:

[0004] Heat dissipation problem: Since the integrated PCS and step-up unit integrates a variety of devices in a relatively small space, its heat dissipation performance may be affected to a certain extent. Especially during high-load operation, if the heat dissipation design is unreasonable or the heat dissipation system fails, the device temperature may rise, which will affect the operation stability and lifespan of the device. However, due to the airtightness of the internal space of the existing integrated cabin of box-type transformer and PCS, the internal heat cannot be quickly dissipated.

[0005] Safety problem: Although safety factors are considered in the design of the integrated cabin of box-type transformer and PCS, there are still certain potential safety hazards during actual operation. For example, if the device fails or is operated improperly, electrical accidents may occur. When an electrical fire occurs, the traditional integrated cabin is not designed with a corresponding fire extinguishing system, resulting in the inability to hinder the development of the fire. In addition, traditional electrical fires are extinguished using dry powder fire extinguishers, but there is a risk that the dry powder particles may damage delicate electronic instruments. Therefore, how to reduce unnecessary damage to the device while achieving fire extinguishing is also an urgent problem to be solved. Summary of the Invention

[0006] The purpose of the present invention is to provide a box-type power control cabinet, which can have a ventilation function, optimize the heat dissipation effect by forming a pressure difference, reduce power consumption by means of heat energy doing work, and can also reduce unnecessary damage to the device while achieving fire extinguishing.

A guide sleeve is fixedly arranged on the outer wall of one end of the energy storage tank. Guide rods are fixedly installed at both ends of the end plate and movably penetrate through the corresponding guide sleeves. A second spring is connected between the ends of the guide rods and the side walls of the corresponding guide sleeves. The other end of the energy storage tank is connected to the end of an injection pipe and is also connected to an outlet pipe. The end of the outlet pipe is connected and assembled with a gas valve. Another interface of the gas valve is connected to a first air pipe. The end of the first air pipe is connected and assembled with a three-way regulating valve.

A waste discharge pipe for discharging waste is connected to the bottom of the other end of the heat-insulating tank.

[0024] The technical effects achieved by the present invention are:

[0025] (1)In the present invention, by means of controlling the downward movement of each half door panel through a through-component, each side box door is provided with a grille opening for ventilation. Under this condition, it is convenient to quickly export the heat inside the integrated control box. The movable half door panel can selectively open the side box door to achieve a ventilation effect, and the opening condition can be determined according to the internal temperature environment and the external weather environment.

[0026] (2)In the present invention, by opening the second air pipe on the low-pressure side, the high-speed air flow ejected by the inclined nozzle increases the air pressure difference on both sides of the integrated control box. By means of the air pressure difference, an air flow passing through the integrated control box is formed, and the heat accumulated inside the integrated control box is carried away by means of this air flow. In this way, the heat dissipation capacity of the integrated control box is greatly improved, and the power for forming the air pressure difference comes from the high-pressure gas stored inside the energy storage tank. And the power for inflating the energy storage tank comes from the kinetic energy of the movable pipe reciprocating due to the temperature difference. The whole process not only makes full use of the heat energy inside the integrated control box to achieve heat energy work, but also optimizes the power consumption plan of the electrical equipment, and reduces the electrical energy consumed in this process as much as possible.

[0027] (3)In the present invention, the inverted U-shaped air supply pipe can prevent rainwater from entering the injection tank. The setting of the pry bar can realize driving the link rod to move with less force. In addition, the four movable pipes move up and down synchronously and jointly drive the link rod to move, further sharing the required power, making it possible to use the thermal expansion and contraction of the liquid as the kinetic energy.

[0028] (4)In the present invention, when an electrical fire occurs, by introducing the high-pressure gas in the energy storage tank into the sodium bicarbonate storage tank, it promotes the reaction between the sodium bicarbonate substance and the citric acid substance and generates a large amount of carbon dioxide gas. By means of the carbon dioxide gas, the effect of extinguishing the fire inside the integrated control box is achieved. Among them, the heat insulation effect of the heat insulation tank can prevent the citric acid from decomposing due to heat, and the desiccant can be used to absorb the water generated by the reaction, avoiding damage to the electrical equipment caused by moisture. In addition, using carbon dioxide to extinguish the fire can reduce the damage to the electrical equipment compared with dry powder extinguishing, and avoid the risk of dry powder damaging precision instruments.

[0041] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.

[0042] As Figures 1 - 10 shown, a box-type power control cabinet includes an integrated control box 1. Side box doors 2 are symmetrically hinged and installed on the side walls of the main power equipment storage room of the integrated control box 1. A penetrating component 3 for opening the ventilation function of the cabinet body is arranged at the top inside the integrated control box 1. A temperature difference power component 4 is arranged at the top of one end of the integrated control box 1. A single negative pressure energy storage component 5 for making the air pressure on one side of the cabinet body lower than that on the other side is arranged at the top of the middle part of the integrated control box 1. A fire fighting component 6 for fire fighting is arranged at the top of the other end of the integrated control box 1. Anemometers 7 for detecting wind speed are fixedly installed at the top of the middle parts of both side walls of the integrated control box 1.

[0043] Embodiment 1:

[0044] See attached Figure 6 A door blocker 101 and a swivel seat 102 are fixedly provided on the inner wall of the integrated control box 1 and at the top of each side box door 2 , and the swivel seat 102 is provided on the inner side of the door blocker 101 .

[0045] See attached Figures 3 - 4 The upper part of the inner wall of the side box door 2 is provided with a door groove 201, and the upper part of the side box door 2 is penetrated with a through hole 202 in an array manner, the inner wall of the side box door 2 is fixedly provided with a bottom block 203 at the bottom of the door groove 201, the inside of the door groove 201 is slidably assembled with a half door panel 204, and the half door panel 204 is penetrated with a through hole 205 in an array manner, the bottom of the half door panel 204 is connected with a spring 206 and connected to the corresponding bottom block 203, and the top of the inner wall of the half door panel 204 is fixedly welded with a vertical pin 207.

[0046] According to the above structure, when all the side box doors 2 are closed and the half door panel 204 slides down and squeezes the corresponding spring 1 206, the opening 1 202 on the upper part of the side box door 2 and the opening 2 205 on the half door panel 204 will overlap and communicate with each other. At this time, the integrated control box 1 will have a large window for air circulation, which is convenient for quickly discharging the internal heat of the integrated control box 1.

[0047] See attached Figure 3 The through assembly 3 includes a cylinder 302 and a base 304 fixedly mounted on the top of the inner wall of the integrated control box 1, and the base 304 is arranged on the inner side of the junction of the two side box doors 2. The top of the inner wall of the integrated control box 1 is slidably assembled with a plate frame 301, and the telescopic output end of the cylinder 302 is fixedly connected to the plate frame 301, and the four corners of the plate frame 301 are integrally provided with groove rods 303;

[0048] See attached Figures 3 - 5 The bottom of the base 304 is rotatably assembled with gear 1 305 and gear 2 306, gear 1 305 is meshed with gear 2 306, and the bottom of gear 1 305 is coaxially fixedly assembled with a sprocket 307, the top of gear 2 306 is coaxially fixedly assembled with an eccentric wheel, and the end of the eccentric wheel away from the center of the circle is fixedly welded with a vertical rod 308, and the vertical rod 308 movably passes through the corresponding slot rod 303.

[0049] See attached Figures 3 - 5, a sleeve frame 309 is fixedly arranged on the inner wall of the integrated control box 1 and above each turntable 102. A rotating cylinder 310 is rotationally assembled inside each turntable 102, and a spiral guide groove 311 is formed on the inner wall of the rotating cylinder 310. A rectangular through rod 312 is slidably assembled inside the sleeve frame 309. A through column 313 penetrating the corresponding rotating cylinder 310 is integrally arranged at the bottom of the rectangular through rod 312. A spherical protrusion 314 is fixedly arranged on the outer wall of the through column 313, and the spherical protrusion 314 is slidably embedded inside the corresponding spiral guide groove 311. A semi-cylindrical body 315 is integrally arranged at the bottom of the through column 313. When the side box door 2 is closed, the vertical pin 207 is embedded inside the corresponding semi-cylindrical body 315. The sprocket 307 is drivingly connected with the adjacent two rotating cylinders 310 through a sleeved chain 316.

[0050] According to the above structure, after the side box door 2 is closed, the vertical pins 207 at the tops of the half door panels 204 will be embedded inside the corresponding semi-cylindrical bodies 315. When the ventilation function of the control box needs to be turned on, the air cylinder 302 is started to drive the plate frame 301 to move horizontally. Since each of the vertical rods 308 penetrates the corresponding groove rod 303, when the plate frame 301 moves, it will drive each second gear 306 to rotate together. Then, by means of the meshing of the first gear 305 and the second gear 306, the sprocket 307 is driven to rotate, and then the corresponding rotating cylinder 310 is driven to rotate through the chain 316. After the rotating cylinder 310 rotates, according to the helix direction of the spiral guide groove 311, the through column 313 and the rectangular through rod 312 will move straight down, and finally the vertical pin 207 is pushed downward through the semi-cylindrical body 315. Each half door panel 204 will move downward simultaneously, causing the first vent 202 and the second vent 205 to coincide, so that the integrated control box 1 has a large-area window for air flow. In the above process, by means of the through component 3 controlling the downward movement of each half door panel 204, each side box door 2 has a grille for ventilation. Under this condition, it is convenient to quickly export the heat inside the integrated control box 1. The movable half door panel 204 can selectively open the ventilation effect of the side box door 2, and the opening condition can be determined according to the internal temperature environment and the external weather environment.

[0051] The working principle of the present invention is as follows: After the side box door 2 is closed, the vertical pins 207 at the tops of the half door panels 204 will be inserted into the inner sides of the corresponding half cylinders 315. When the ventilation function of the control box needs to be activated, the cylinder 302 is started to drive the plate frame 301 to move horizontally. Since each of the vertical rods 308 passes through the corresponding groove rod 303, when the plate frame 301 moves, it will drive each of the second gears 306 to rotate together. Then, by means of the meshing of the first gear 305 and the second gear 306, the sprocket 307 is driven to rotate, and then the corresponding rotating cylinder 310 is driven to rotate through the chain 316. After the rotating cylinder 310 rotates, according to the helix direction of the spiral guide groove 311, the through column 313 connecting the rectangular through rod 312 will move straight down, and finally the vertical pin 207 will be pushed downward through the half cylinder 315. When each half door panel 204 moves downward and compresses the corresponding first spring 206, the through hole one 202 in the upper half of the side box door 2 and the through hole two 205 in the half door panel 204 will coincide and communicate. At this time, the integrated control box 1 has a large-area window for air flow, which is convenient for quickly discharging the heat inside the integrated control box 1.

[0052] Embodiment 2:

[0053] Refer to the attached Figures 6 - 7 , the temperature difference power assembly 4 includes several groups of integrated copper pipes one 401 and copper pipes two 404. There are four groups of integrated copper pipes one 401 and copper pipes two 404, which are symmetrically distributed. The copper pipes one 401 are fixedly installed on the lower surface of the top plate of the integrated control box 1, and the copper pipes two 404 are fixedly installed on the upper surface of the top plate of the integrated control box 1. The copper pipes two 404 are located directly above the corresponding copper pipes one 401, and a heat insulation filler 408 is filled between the two. A movable pipe 402 is slidably assembled inside the copper pipe one 401. A liquid plug 405 is fixedly arranged inside the copper pipe two 404, and the liquid plug 405 extends into the corresponding movable pipe 402. A copper sleeve 403 is embedded and sleeved on the outer wall of the top of the movable pipe 402, and silicone oil 406 is filled in the upper half of the inside of the movable pipe 402. A coolant tank 407 is hermetically assembled on the top of each copper pipe two 404, and cooling water is stored inside the coolant tank 407. A connecting block 409 is fixedly arranged at the bottom of each movable pipe 402.

[0054] Refer to the attached Figures 6 - 7, at the top of one end of the integrated control box 1, pry bars 410 are rotatably installed. The four pry bars 410 are divided into two groups and are symmetrically arranged. The end of the pry bar 410 away from the fulcrum is connected to the corresponding connecting block 409. One end of the top plate of the integrated control box 1 is fixedly installed in a penetrating manner with an air injection tank 412. An air plug member is telescopically assembled inside the air injection tank 412, and the bottom end of the air plug member extending outside the air injection tank 412 is fixedly connected to a connecting rod 411. The connecting rod 411 is connected to the ends of the four pry bars 410 close to the fulcrum, and the connecting rod 411 is arranged in a lifting manner at the top of one end of the integrated control box 1. The top of the air injection tank 412 is fixedly connected with an air injection pipe 413 and a supplementary air pipe 414 respectively, and one-way valves are assembled at the ends of the air injection pipe 413 and the supplementary air pipe 414 close to the air injection tank 412. The supplementary air pipe 414 is in an inverted U shape.

[0055] According to the above structure, the copper pipe 401 inside the integrated control box 1 is heated by the high temperature inside the box. When the copper sleeve 403 is placed inside the copper pipe 401, the high temperature of the copper pipe 401 is conducted to the copper sleeve 403 and directly heats the silicone oil 406 inside the movable pipe 402. By virtue of the high-temperature resistance and heat-induced expansion characteristics of the silicone oil 406, the movable pipe 402 moves upward under the power of liquid expansion. As the movable pipe 402 moves, the copper sleeve 403 will move into the copper pipe 404. The cooling water inside the coolant tank 407 directly cools the silicone oil 406 through the temperature conduction between the copper pipe 404 and the copper sleeve 403. The silicone oil 406 contracts when cooled, causing the movable pipe 402 to move downward again. The heat insulation filling 408 is used to prevent temperature conduction between the copper pipe 401 and the copper pipe 404. In this way, the movable pipe 402 will continuously move up and down, and the movable pipe 402 can reciprocally pry the corresponding pry bar 410. Finally, the connecting rod 411 will be driven to reciprocally move up and down, and the air plug member continuously moves telescopically inside the air injection tank 412, causing positive and negative pressures to be continuously formed inside the air injection tank 412. External air is inhaled into the air injection tank 412 through the supplementary air pipe 414 and is then extruded through the air injection pipe 413;

[0056] Furthermore, the inverted U-shaped supplementary air pipe 414 can prevent rainwater from entering the air injection tank 412. The setting of the pry bar 410 can achieve driving the movement of the connecting rod 411 with a smaller force. In addition, the four movable pipes 402 move up and down synchronously and jointly drive the movement of the connecting rod 411, further sharing the required power, making it possible to use the thermal expansion and contraction of liquid as kinetic energy.

[0057] Refer to the appendix Figures 8 - 9, the single negative pressure energy storage component 5 includes an energy storage tank 501 fixedly installed above the integrated control box 1. A piston 502 is telescopically assembled inside the energy storage tank 501, and one end of the piston 502 extending outside the energy storage tank 501 is fixedly connected to an end plate 503. A guide sleeve 505 is fixedly arranged on the outer wall of one end of the energy storage tank 501. Guide rods 504 movably penetrating the corresponding guide sleeves 505 are fixedly installed at both ends of the end plate 503, and a second spring 506 is connected between the end of the guide rod 504 and the side wall of the corresponding guide sleeve 505. The other end of the energy storage tank 501 is connected to the end of the injection pipe 413 and is also connected to an outlet pipe 507. The end of the outlet pipe 507 is connected and assembled with a gas valve 508. Another interface of the gas valve 508 is connected to a first air pipe 509. The end of the first air pipe 509 is connected and assembled with a three-way regulating valve 514. The other three interfaces of the three-way regulating valve 514 are respectively connected to two second air pipes 515 and a relief pipe 519. The two second air pipes 515 are fixedly installed at the top of both sides inside the integrated control box 1, and inclined nozzles 516 inclined towards the side box door 2 are arrayedly installed on the outer wall of the second air pipe 515.

[0058] Refer to the appendix Figures 8 - 9 , a valve core 510 for controlling the dredging of the outlet pipe 507 and the first air pipe 509 is slidably installed inside the gas valve 508. A lever 512 is fixedly connected to the bottom of the end plate 503, and ejector rods 513 for pushing the valve core 510 are symmetrically and fixedly welded at both ends of the lever 512. A channel 511 is penetratively opened in the middle of the valve core 510. The three-way regulating valve 514 is electrically connected to two anemometers 7. One end of the outlet pipe 507 is fixedly connected to a branch pipe 517, and a solenoid valve 518 is connected and assembled at the end of the branch pipe 517 close to the outlet pipe 507. A fire alarm is installed on the inner wall of the integrated control box 1, and the fire alarm is electrically connected to the solenoid valve 518.

[0059] According to the above structure, when the ventilation function of the control box is not turned on, the three-way regulating valve 514 is controlled to make the air pipe 1 509 and the air release pipe 519 open. When the ventilation function of the control box is turned on, the anemometers 7 located on both sides of the integrated control box 1 are used to detect the wind speed on both sides of the box. According to the principle that the wind speed has a small atmospheric pressure, the three-way regulating valve 514 is controlled to open the air pipe 2 515 located at the low pressure position. In addition, air is continuously injected into the energy storage tank 501 through the air injection pipe 413, the piston 502 will move and the corresponding spring 2 506 will be compressed at the same time. When the piston 502 moves to the limit position, the push rod at one end of the lever 512 513 will push the valve core 510, so that the channel 511 connects the air outlet pipe 507 and the air pipe 1 509. At this time, the high-pressure gas inside the energy storage tank 501 will be quickly squeezed into the air pipe 2 515 on the corresponding side, and finally sprayed to the side box door 2 on one side through the oblique nozzle 516. At this time, a high-speed airflow will pass through the vicinity of the side box door 2 located at the low-pressure position, and the air pressure in this position will be further reduced by this airflow. At this time, the air pressure on the other side of the integrated control box 1 is higher than that on this side. With the help of the air pressure difference on both sides, the air on the other side is driven to pass through the integrated control box 1 to move to this side, and the heat accumulated inside the integrated control box 1 is taken away by this airflow;

[0060] In the above process, by opening the air pipe 2 515 on the low-pressure side, the high-speed airflow ejected from the oblique nozzle 516 increases the pressure difference on both sides of the integrated control box 1, and forms an airflow passing through the integrated control box 1 with the help of the pressure difference. The heat accumulated inside the integrated control box 1 is taken away with the help of the airflow, and the heat dissipation capacity of the integrated control box 1 is greatly improved in this way. The power for forming the pressure difference comes from the high-pressure gas stored in the energy storage tank 501, and the power for inflating the energy storage tank 501 comes from the kinetic energy of the reciprocating motion of the live tube 402 with the help of the temperature difference. The whole process not only makes full use of the thermal energy inside the integrated control box 1 to achieve thermal energy work, but also optimizes the scheme for using power equipment to reduce the power consumed in the process as much as possible.

[0061] The working principle of the present invention is: when the ventilation function of the control box is not turned on, the three-way regulating valve 514 is controlled to open the air pipe 1 509 and the air release pipe 519. When the ventilation function of the control box is turned on, the anemometers 7 located on both sides of the integrated control box 1 are used to detect the wind speed on both sides of the box. Based on the principle that the wind speed has a small atmospheric pressure, the three-way regulating valve 514 is controlled to open the air pipe 2 515 located at the low pressure position.

[0062] The copper pipe 401 inside the integrated control box 1 is heated by the high temperature inside the box. When the copper sleeve 403 is placed inside the copper pipe 401, the high temperature of the copper pipe 401 conducts to the copper sleeve 403 and directly heats the silicone oil 406 inside the movable pipe 402. By virtue of the high temperature resistance and thermal expansion characteristics of the silicone oil 406, the movable pipe 402 moves upward under the power of liquid expansion. As the movable pipe 402 moves, the copper sleeve 403 will move into the copper pipe 404. The cooling water inside the coolant tank 407 directly cools the silicone oil 406 through the temperature conduction between the copper pipe 404 and the copper sleeve 403. The cold shrinkage of the silicone oil 406 causes the movable pipe 402 to move downward again. The heat insulation filling 408 is used to prevent temperature conduction between the copper pipe 401 and the copper pipe 404. In this way, the movable pipe 402 will continuously move up and down, and the movable pipe 402 can reciprocally pry the corresponding pry bar 410. Finally, the connecting rod 411 will be driven to reciprocally move up and down, and the air plug will continuously expand and contract inside the air injection tank 412, causing positive and negative pressures to be continuously formed inside the air injection tank 412. External air is inhaled into the air injection tank 412 through the air supply pipe 414 and is then extruded through the air injection pipe 413;

[0063] Air is continuously injected into the energy storage tank 501 through the air injection pipe 413, and the piston 502 will move and the corresponding spring two 506 will be compressed simultaneously. When the piston 502 moves to the limit position, the ejector rod 513 at one end of the lever 512 will push the valve core 510, causing the passage 511 to connect the air outlet pipe 507 and the air pipe one 509. At this time, the high-pressure gas inside the energy storage tank 501 will be quickly squeezed into the air pipe two 515 on the corresponding side and will finally be sprayed towards the side box door 2 on one side through the inclined nozzle 516. At this time, high-speed air flow will pass through near the side box door 2 in the low-pressure position. By virtue of this air flow, the air pressure in this position is further reduced. At this time, the air pressure on the other side of the integrated control box 1 is higher than that on this side. By virtue of the air pressure difference between the two sides, the air on the other side is driven to pass through the integrated control box 1 and move to this side, and the heat accumulated inside the integrated control box 1 is taken away by this air flow. When the gas inside the energy storage tank 501 is exhausted, the piston 502 and the lever 512 return to their original positions, and the ejector rod 513 at the other end of the lever 512 will also push the valve core 510 to return to its original position. The air outlet pipe 507 and the air pipe one 509 will be disconnected and closed, and the air injection pipe 413 will re-inflate the energy storage tank 501.

[0064] Embodiment 3:

[0065] Refer to the appendix Figure 10, the fire-fighting component 6 includes a heat-insulating tank 601 fixedly installed above the integrated control box 1. Inside the heat-insulating tank 601, a sodium bicarbonate storage tank 602 and a citric acid storage tank 605 are fixedly arranged. One end of the sodium bicarbonate storage tank 602 extending out of the interior of the heat-insulating tank 601 is connected to the end of the branch pipe 517, and the end of the sodium bicarbonate storage tank 602 away from the branch pipe 517 is connected to the citric acid storage tank 605 through a conduit. A push plug 603 is slidably assembled inside the sodium bicarbonate storage tank 602 near the branch pipe 517, and a first stopper 604 is slidably assembled inside the sodium bicarbonate storage tank 602 near the conduit. A second stopper 606 is installed inside the outlet pipe of the citric acid storage tank 605.

[0066] Refer to the appendix Figure 10 , one end of the heat-insulating tank 601 is connected to a fire-fighting pipe 607, and a filter cover 608 is sleeved on the end of the fire-fighting pipe 607 located inside the heat-insulating tank 601. The interior of the heat-insulating tank 601 is filled with a desiccant. The fire-fighting pipe 607 extends and is installed at the top end inside the integrated control box 1, and a nozzle 609 is arrayedly connected and installed on the outer wall of the fire-fighting pipe 607. A waste discharge pipe 610 for discharging waste is connected to the bottom of the other end of the heat-insulating tank 601.

[0067] According to the above structure, when the fire alarm inside the integrated control box 1 detects a fire, the solenoid valve 518 is opened, and the high-pressure gas in the energy storage tank 501 will be injected into the sodium bicarbonate storage tank 602 through the branch pipe 517. The push plug 603 will push the sodium bicarbonate substance, the first stopper 604 will be pushed open, and the sodium bicarbonate substance will enter the citric acid storage tank 605 through the conduit. The reaction between the sodium bicarbonate substance and the citric acid substance will generate a large amount of carbon dioxide gas and water. Among them, the water will be absorbed by the desiccant inside the heat-insulating tank 601, and the carbon dioxide gas will be injected into the integrated control box 1 through the fire-fighting pipe 607 and the nozzle 609 to achieve the effect of extinguishing the fire. In the above process, when an electrical fire occurs, by introducing the high-pressure gas in the energy storage tank 501 into the sodium bicarbonate storage tank 602, it prompts the reaction between the sodium bicarbonate substance and the citric acid substance and generates a large amount of carbon dioxide gas, and uses the carbon dioxide gas to achieve the effect of extinguishing the fire inside the integrated control box 1. Among them, the heat-insulating effect of the heat-insulating tank 601 can prevent the citric acid from decomposing due to heat, and the desiccant can be used to absorb the water generated by the reaction to avoid water damage to electrical equipment. In addition, using carbon dioxide to extinguish the fire can reduce the damage to electrical equipment compared with dry powder extinguishing and avoid the risk of dry powder damaging precision instruments.

[0068] The working principle of the present invention is as follows: When the fire alarm inside the integrated control box 1 detects a fire, the solenoid valve 518 is opened, and the high-pressure gas in the energy storage tank 501 will be injected into the sodium bicarbonate storage tank 602 through the branch pipe 517. The push plug 603 will push the sodium bicarbonate substance, the first blocking plug 604 will be pushed open, and the sodium bicarbonate substance will enter the citric acid storage tank 605 through the conduit. The reaction between the sodium bicarbonate substance and the citric acid substance will generate a large amount of carbon dioxide gas and water. Among them, the water will be absorbed by the desiccant inside the heat insulation tank 601, and the carbon dioxide gas will be injected into the integrated control box 1 through the fire pipe 607 and the nozzle 609. By reducing the oxygen concentration in the air, the combustion of the flame is suffocated, achieving the effect of extinguishing the fire. Moreover, when the carbon dioxide is released to the fire scene, it will expand into a gas and absorb heat, thereby reducing the temperature around the flame and further suppressing the combustion of the flame.

[0069] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
