Description

Technical Field

[0001] This invention relates to the field of remote monitoring technology for synchronous condensers, specifically to a centralized control device for monitoring synchronous condensers in power grids. Background Technology

[0002] A synchronous condenser is a special type of synchronous motor whose main function is to provide or absorb reactive power to maintain grid voltage stability (especially in ultra-high voltage and long-distance transmission systems). When the grid load fluctuates or a fault occurs, the synchronous condenser can respond quickly to compensate for reactive power deficits and prevent voltage collapse. It is a key device for "reactive power support" of the power grid. However, for remote monitoring, operation management, and fault early warning, the synchronous condenser often needs to be equipped with existing centralized control and monitoring devices.

[0003] When using current synchronous condenser monitoring and control equipment, if the power of the internal modules increases abnormally, causing the internal temperature to rise abnormally, and if the temperature exceeds the threshold, it will shorten the lifespan of each module or even damage it, leading to distorted monitoring data. If the internal components short-circuit, causing the temperature to rise and triggering an arc fire, it will also affect the normal remote indication and monitoring of the synchronous condenser. Moreover, firefighting often requires separate fire-fighting equipment, which increases the overall space and cost. At the same time, firefighting can damage the normal components inside the equipment, rendering them unusable and increasing maintenance and replacement costs.

[0004] To address the above issues, a centralized control device for monitoring and controlling synchronous condensers in power grids is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a power grid synchronous condenser monitoring and control device. By using this invention, the problems mentioned above can be solved, such as when the power of the modules and components inside the device increases abnormally, leading to an abnormal rise in the internal temperature of the device, or when a fire occurs, the service life of each module and component is shortened or even damaged, resulting in the distortion of monitoring data. Furthermore, the fire extinguishing process can damage the normal components inside the device, rendering them unusable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power grid synchronous condenser monitoring and control device, comprising a monitoring chassis and a module plate installed in the middle of the inner side of the monitoring chassis, a pushing mechanism installed on the upper outer side of the monitoring chassis, and a vent provided on one side of the top of the monitoring chassis, a temperature sensor installed on the upper inner side of the monitoring chassis, and a smoke sensor installed on one side of the temperature sensor, a moving mechanism provided on the lower side of one side of the pushing mechanism, and a switching mechanism provided at the bottom of the moving mechanism; A circulation mechanism is provided on the top of the outer side of the monitoring box. A spraying mechanism is connected to one side of the moving mechanism, and the moving mechanism and the circulation mechanism are connected. A water inlet is provided at the bottom of the monitoring box, and a collection mechanism is installed at the bottom of the monitoring box, and the collection mechanism and the water inlet are connected. An installation cover is installed on one side of the top of the circulation mechanism.

[0007] Furthermore, the pushing mechanism includes an electric pusher cylinder fixed on one side above the monitoring housing, and a sealing plate is installed at the output end of the electric pusher cylinder. Limiting plates are fixed on both sides above the vent, and the sealing plate is slidably connected to the monitoring housing through the limiting plates.

[0008] Furthermore, a movable plate is fixed to the middle of one side of the sealing plate, and a first inclined surface is provided in the middle of the lower surface of the movable plate, and a second inclined surface is provided on one side of the lower surface of the movable plate.

[0009] Furthermore, the moving mechanism includes a liquid storage tank fixed to one side of the upper end of the monitoring box, and a lifting rod is slidably arranged inside the liquid storage tank, with a contact head fixed to the top of the lifting rod.

[0010] Furthermore, a support spring is provided on the lower exterior of the lifting rod, and a fixed support plate is fixed to the bottom of the lifting rod. The fixed support plate is elastically connected to the liquid storage tank through the support spring, and a sealing block is fixed in the middle of the lifting rod.

[0011] Furthermore, a mounting frame is fixed inside the monitoring chassis, and a conductive base is fixed at the front end of the mounting frame. Connecting springs are fixed on both sides inside the conductive base, and a conductive plate is fixed on the top of the connecting springs. Two sets of cables are connected to the bottom of the conductive base.

[0012] Furthermore, the circulation mechanism includes a heat dissipation box fixed to one side of the top of the monitoring chassis. A water pump is connected to the lower side of one side of the heat dissipation box, and the output end of the water pump is connected to a water outlet pipe, which is connected to a liquid storage tank.

[0013] Furthermore, a water pipe is connected to the upper side of one side of the liquid storage tank, and a water hood is connected to the bottom of the water pipe. A return water pipe is connected to the bottom of one side of the water hood, and the water hood is connected to the heat dissipation box via the return water pipe.

[0014] Furthermore, the spraying mechanism includes a water guide pipe connected to the lower side of one side of the liquid storage tank, and a water distribution pipe connected to one side of the water guide pipe. A connecting pipe is connected to the lower part of the water distribution pipe, and several spray nozzles are vertically installed on one side surface of the connecting pipe.

[0015] Furthermore, the collection mechanism includes a collection box fixed to the bottom of the monitoring chassis, and a second water pump is connected to one side of the collection box. The output end of the second water pump is connected to a return pipe, and the collection box is connected to the heat dissipation box through the second water pump and the return pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the internal temperature of the equipment is found to rise abnormally and exceed the threshold, the present invention will trigger the switching mechanism, which will disconnect the entire circuit of the monitoring chassis. The switching mechanism will record the instantaneous data of the circuit breaker's opening or closing status, as well as record and remotely transmit various data monitored by the power grid synchronous condenser. This avoids data loss after the switching mechanism cuts off the power. At the same time, after the switching mechanism cuts off the power to the whole system, it can prevent the equipment from malfunctioning and causing the temperature to continue to rise, which could easily lead to electrical short circuits and other expanded faults. This ensures the safety and lifespan of the monitoring chassis.

[0017] 2. When smoke is detected inside the equipment, this invention can perform contact cooling and fire extinguishing on the module components, cutting off the fire at its source and preventing the fire from spreading and causing serious damage to the equipment. At the same time, the sprayed fluorinated liquid is insulating, and direct contact with electrically powered components will not cause short circuits while extinguishing the fire. Moreover, the fluorinated liquid is chemically inert and does not react with the materials of components and circuit boards. There is no need to disassemble and clean after spraying, which can avoid damage to normal components inside the equipment. This allows other normal components to resume normal and timely operation, avoiding the problem of poor contact and heat dissipation obstruction of components due to the residue of traditional fire extinguishing agents, which leads to scrap and unusability.

[0018] 3. The fluorinated liquid sprayed in this invention can directly contact the surface of components to improve the cooling effect, ensuring that the equipment has good monitoring accuracy and service life. At the same time, the collection mechanism can recycle the fluorinated liquid, enabling the equipment to carry out long-term and effective cooling and fire protection treatment. Furthermore, the fluorinated liquid is used for circulating heat dissipation and can be directly sprayed in case of high temperature or fire, eliminating the need for a separate fire-fighting unit, realizing integrated heat dissipation and fire-fighting, and reducing the cost of independent equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical problem of distorted monitoring data caused by abnormally increased power in internal modules leading to abnormally high internal temperatures, which, if exceeding a threshold, shorten the lifespan of individual modules or even damage them, such as... Figure 1 - Figure 6 As shown, the following preferred technical solutions are provided: A centralized control device for monitoring and controlling synchronous condensers in a power grid includes a monitoring chassis 1 and a module plate 2 installed in the middle of the inner side of the monitoring chassis 1. A module assembly is located on the front side of the module plate 2. This module assembly is an internal module assembly of a prior art centralized control and monitoring device for synchronous condensers, capable of remotely indicating and monitoring the network status of the synchronous condensers, as well as controlling the switching on and off of the synchronous condensers. Its specific working principle is not detailed here. The monitoring chassis 1 is sealed to its external chassis door, preventing leakage during normal operation. A pushing mechanism 3 is installed on the upper outer side of the monitoring chassis 1, and a vent 20 is provided on one side of the top of the monitoring chassis 1. A dustproof net is fixed inside the vent 20 to ensure ventilation and heat dissipation inside the monitoring chassis 1. A temperature sensor 9 is installed on the upper inner side of the monitoring chassis 1. This temperature sensor 9 is based on existing principles and can monitor the temperature of the monitoring chassis. The internal temperature of the monitoring unit 1 is detected, and a smoke sensor 10 is installed on one side of the temperature sensor 9. The existing smoke sensor 10 can detect whether there is smoke inside the monitoring unit 1. A moving mechanism 4 is set below one side of the pushing mechanism 3, and a switching mechanism 5 is set at the bottom of the moving mechanism 4. The switching mechanism 5 is the overall circuit switch of the monitoring unit 1. The normal operating temperature of the monitoring unit 1 of the existing power grid synchronous condenser centralized control monitoring device is about 40 degrees Celsius. When the power of the module components increases abnormally, the internal temperature of the equipment rises abnormally. If the temperature exceeds the threshold, such as 70 degrees Celsius, it will shorten the service life of each module component or even damage it, resulting in the distortion of the monitoring data. If the components inside the equipment short-circuit, the temperature will also rise and trigger an electric arc fire, which will also affect the normal operation of remote indication and monitoring of the synchronous condenser.

[0023] At this point, using temperature sensor 9, when an abnormal increase in the internal temperature of the equipment is detected and exceeds the threshold, the existing principle controller independently installed outside the equipment will cause the push mechanism 3 to make an initial pushing action. Under the initial pushing movement of the push mechanism 3, the moving mechanism 4 will be triggered first, causing the moving mechanism 4 to move upward a certain distance initially. When the moving mechanism 4 moves upward initially, it will trigger the switching mechanism 5, causing the switching mechanism 5 to disconnect the overall circuit of the monitoring box 1. Before the switching mechanism 5 disconnects, the monitoring module components on the module board 2 will record the instantaneous data of the circuit breaker's opening or closing status, as well as the various monitoring data of the power grid synchronous condenser. Data is recorded and transmitted remotely to prevent data loss after the power is cut off by the switch mechanism 5. The data signals sent by the module components will also remind the staff to inspect and maintain the equipment. At the same time, after the power is cut off by the switch mechanism 5, it can prevent the equipment from malfunctioning and causing the temperature to rise continuously, which may easily lead to electrical short circuits and other expanded faults, thus ensuring the safety and lifespan of the monitoring box 1. After the power is cut off by the switch mechanism 5 and the staff has inspected and confirmed that the equipment is in good condition, the initial pushing mechanism 3 will move back, causing the initial upward moving mechanism 4 to move down again, so that the switch mechanism 5 can be powered on again, allowing the equipment to perform monitoring work normally.

[0024] A circulation mechanism 6 is installed on the top of the outer side of the monitoring housing 1. The circulation mechanism 6 is a cooling circulation structure that can circulate the fluorinated liquid inside the monitoring housing 1, thereby removing the heat generated when the monitoring housing 1 is working, achieving the effect of cooling the equipment. A spray mechanism 7 is connected to one side of the moving mechanism 4, and the moving mechanism 4 is connected to the circulation mechanism 6. When the monitoring housing 1 is working normally, and when the temperature rises abnormally, the moving mechanism 4 will always block the connection part of the spray mechanism 7 when the pushing mechanism 3 and the moving mechanism 4 move initially, and only maintain communication with the circulation mechanism 6. This ensures that the cooled fluorinated liquid will only circulate and cool in the circulation mechanism 6, and will not flow into the spray mechanism 7. When the smoke sensor 10 detects smoke generated inside the equipment, the pushing mechanism 3 will also move initially and eventually cut off the power to the switching mechanism 5. At the same time, the pushing mechanism 3 will push forward a second time. When the pushing mechanism 3 pushes forward a second time, it will block the vent 20, so that a closed space is formed inside the monitoring housing 1.

[0025] Simultaneously, when the pushing mechanism 3 pushes forward a second time, the moving mechanism 4 also moves upward a second time. During this upward movement, the circulating cooling path of the circulation mechanism 6 is blocked, while the path of the spraying mechanism 7 is opened. At this point, the fluorinated liquid is finally sprayed from the spraying mechanism 7 onto the surface of the module components on the module board 2, thus providing contact cooling and fire extinguishing. This cuts off the fire at its source, preventing the fire from spreading and causing serious damage to the equipment. This makes the remote indication and monitoring of the power grid synchronous condenser safer and more reliable. Furthermore, the sprayed fluorinated liquid is insulating; while extinguishing the fire, direct contact with electrically powered components will not cause a short circuit. The fluorinated liquid is also chemically inert and does not react with copper, aluminum, epoxy resin, or other components and circuit board materials. No disassembly and cleaning are required after spraying, avoiding damage to the equipment. Damage to normally functioning components within the equipment ensures that other normally functioning components can resume normal and timely operation. This avoids the problem of components becoming unusable due to poor contact and heat dissipation obstruction caused by residual fire extinguishing agents. The pushing mechanism 3, circulation mechanism 6, temperature sensor 9, and smoke sensor 10 are controlled by a separate existing principle controller outside the equipment and are powered independently by an external power source (not shown in the diagram). This ensures that the equipment can still detect and take protective actions even when power is off. At the same time, when the smoke sensor 10 detects fire extinguishing spray, the external controller will also transmit a signal, allowing personnel to perform timely maintenance. After fire extinguishing spray, the pushing mechanism 3 will return to its original position, causing the moving mechanism 4 to move down again, closing the spray mechanism 7 and restarting the cooling cycle with the circulation mechanism 6.

[0026] A water inlet 30 is installed at the bottom of the monitoring enclosure 1, and a collection mechanism 8 is installed at the bottom of the monitoring enclosure 1. The collection mechanism 8 is connected to the water inlet 30. After the fluorinated liquid is sprayed for fire extinguishing, the settled fluorinated liquid will flow into the collection mechanism 8. The collection mechanism 8 will then send the collected fluorinated liquid back into the circulation mechanism 6 for recycling. At the same time, when the temperature inside the equipment rises abnormally but no fire occurs, the pushing mechanism 3 can also be pushed forward a second time, causing the fluorinated liquid to spray out and directly contact the surface of the components to improve the cooling effect. This ensures that the equipment has good monitoring accuracy and service life. The boiling point of the fluorinated liquid is above 100 degrees Celsius, far exceeding... The temperature is higher than that under abnormal conditions inside the equipment, so the possibility of fluorinated liquid evaporation and loss is very small when spraying for cooling. At the same time, the collection mechanism 8 is used to recycle the fluorinated liquid, so that the equipment can carry out long-term and effective cooling and fire protection treatment. The fluorinated liquid is used for circulating heat dissipation and can be directly sprayed in case of high temperature or fire, without the need for a separate fire protection unit, realizing heat dissipation and fire protection integration, reducing the cost of independent equipment. A mounting cover 40 is installed on one side of the top of the circulation mechanism 6. The mounting cover 40 is installed on the circulation mechanism 6 with screws. When maintaining the monitoring box 1, the fluorinated liquid can be replenished by opening the mounting cover 40.

[0027] The pushing mechanism 3 includes an electric pusher cylinder 31 fixed on one side above the monitoring housing 1, and a sealing plate 32 is installed at the output end of the electric pusher cylinder 31. Limiting plates 33 are fixed on both sides above the vent 20, and the sealing plate 32 is slidably connected to the monitoring housing 1 through the limiting plates 33. The electric pusher cylinder 31 can push the sealing plate 32 along the limiting plates 33, so that the sealing plate 32 can move to cover the outside of the vent 20. In the event of a fire in the equipment, the vent 20 can be sealed to prevent the spread of smoke and isolate the air flow between the inside and outside of the equipment, thus ensuring the effectiveness of subsequent fire extinguishing.

[0028] A movable plate 34 is fixed to the middle of one side of the sealing plate 32, and a slope 35 is provided in the middle of the lower surface of the movable plate 34, and a slope 36 is provided on one side of the lower surface of the movable plate 34.

[0029] The moving mechanism 4 includes a liquid storage tank 41 fixed to one side of the upper end of the monitoring housing 1, and a lifting rod 42 is slidably arranged inside the liquid storage tank 41. A contact head 43 is fixed to the top of the lifting rod 42. Figure 4 As shown, when the monitoring chassis 1 is working normally, the electric push cylinder 31 and the sealing plate 32 are not pushed, and at this time the contact head 43 is in contact with the front end of the lower surface of the moving plate 34.

[0030] A support spring 44 is provided on the lower exterior of the lifting rod 42, and a fixed support plate 45 is fixed at the bottom of the lifting rod 42. The fixed support plate 45 is elastically connected to the liquid storage tank 41 through the support spring 44. When the contact head 43 is in contact with the front end of the lower surface of the moving plate 34, the support spring 44 is in a stretched state. A sealing block 46 is fixed in the middle of the lifting rod 42.

[0031] The monitoring housing 1 has a fixed bracket 51 inside, and a conductive base 52 is fixed to the front end of the fixed bracket 51. Connecting springs 53 are fixed to both sides inside the conductive base 52. The connecting springs 53 are made of non-conductive material. A conductive plate 54 is fixed to the top of the connecting springs 53. Two sets of cables 55 are connected to the bottom of the conductive base 52. The cables 55 are the power supply wires inside the monitoring housing 1. The two sets of cables 55 are respectively connected to the positive and negative terminals on both sides of the conductive base 52. The conductive plate 54 is made of conductive material. When the monitoring housing 1 is working normally, the conductive plate 54 contacts the conductive base 52 under the pull of the connecting springs 53, so that the cables 55 connect to the circuit inside the monitoring housing 1.

[0032] Using temperature sensor 9, when an abnormal increase in internal temperature is detected exceeding a threshold, the existing principle controller independently installed outside the equipment will cause the electric pusher cylinder 31 to drive the sealing plate 32 and the moving plate 34 to make an initial pushing action. Under the initial pushing movement of the moving plate 34, such as... Figure 5As shown, the contact head 43 will slide upward along the inclined plane 35, causing the lifting rod 42 to move upward along the liquid storage tank 41 under the elastic contraction of the support spring 44. As the lifting rod 42 moves upward, it simultaneously drives the fixed support plate 45 upward. The fixed support plate 45 is inserted between the conductive base 52 and the conductive plate 54. The elastic contraction force of the support spring 44 is much greater than the elastic force of the connecting spring 53. Therefore, when the fixed support plate 45 moves upward, it stretches the connecting spring 53, causing the conductive plate 54 to move upward and separate from the conductive base 52, thus disconnecting the circuit of the cable 55. This disconnects the overall circuit of the monitoring chassis 1. Before the cable 55 disconnects, the monitoring module components on the module board 2 record the instantaneous data of the circuit breaker's opening or closing status, as well as various data from the power grid synchronous condenser, and remotely record and monitor them. The transmission of data through the cable 55 prevents data loss after power failure, and the data signals transmitted by the module components also alert the staff to perform maintenance on the equipment. At the same time, after the cable 55 is powered off, it can prevent abnormal operation of the equipment, which could lead to continuous temperature rise and easily cause electrical short circuits and other expanded faults, thus ensuring the safety and lifespan of the monitoring chassis 1. After the cable 55 is powered off and the staff has inspected and confirmed that the equipment is in good working order, the initially pushed electric push cylinder 31 will drive the sealing plate 32 and the moving plate 34 to move back, causing the contact head 43 to slide down along the inclined plane 35. This allows the lifting rod 42 and the fixed support plate 45 to move down and re-stretch the support spring 44, causing the conductive plate 54 and the connecting spring 53 to lose their lifting force and re-contact with the conductive base 52, allowing the cable 55 to be powered on again and enabling the equipment to perform monitoring work normally.

[0033] To address the technical problem that if a short circuit occurs in the equipment's internal components, causing a temperature rise and triggering an electric arc fire, which would also affect the normal operation of the remote indication and monitoring of the synchronous condenser, and that extinguishing the fire would damage normal components within the equipment, rendering them unusable and increasing maintenance and replacement costs, such as... Figure 1 - Figure 8 As shown, the following preferred technical solutions are provided: The circulation mechanism 6 includes a heat sink 61 fixed to one side of the top of the monitoring housing 1. The heat sink 61 has a flow chamber for circulating the fluorinated liquid. The surface of the heat sink 61 is provided with heat dissipation fins to cool the circulating fluorinated liquid. A water pump 62 is connected to the lower side of one side of the heat sink 61. The output end of the water pump 62 is connected to a water outlet pipe 63, which is connected to a storage tank 41. The water pump 62 can pump the fluorinated liquid into the storage tank 41.

[0034] A water pipe 64 is connected to the upper side of the liquid storage tank 41, and a water hood 65 is connected to the bottom of the water pipe 64. The water hood 65 is arranged in an inverted U-shape along the inner wall of the monitoring box 1, and fluorinated liquid is placed inside the water hood 65. A return water pipe 66 is connected to the bottom of one side of the water hood 65, and the water hood 65 is connected to the heat dissipation box 61 through the return water pipe 66. By using the pump 62, the fluorinated liquid can be circulated inside the monitoring box 1, thereby removing the heat generated inside the monitoring box 1 during operation and achieving the effect of cooling the equipment.

[0035] The spraying mechanism 7 includes a water guide pipe 71 connected to the lower side of the liquid storage tank 41, and a water distribution pipe 72 connected to one side of the water guide pipe 71. A connecting pipe 73 is connected to the lower part of the water distribution pipe 72, and several spray nozzles 74 are vertically installed on one side surface of the connecting pipe 73. When the monitoring box 1 is working normally, and when the temperature rises abnormally and causes the moving plate 34 to initially move the lifting rod 42 upward, the blocking block 46 will initially move upward with the lifting rod 42. The blocking block 46, during the initial movement and the initial movement, will always block the inlet of the water guide pipe 71, so that the liquid storage tank 41 is only connected to the water pipe 64. This ensures that the cooling fluorinated liquid flows only from the water pipe 64 into the water hood 65 for cooling, and does not flow into the water pipe 71. When the module used for remote indication and monitoring inside the equipment short-circuits and catches fire, and the smoke sensor 10 detects smoke inside the equipment, the electric push cylinder 31 will initially move the sealing plate 32 and the moving plate 34. Finally, while the cable 55 is de-energized, the electric push cylinder 31 will push the sealing plate 32 and the moving plate 34 forward a second time. When the moving plate 34 pushes forward a second time, it will block the vent 20, thus forming a closed space inside the monitoring box 1.

[0036] Simultaneously, when the moving plate 34 pushes forward a second time, the contact head 43 will eventually slide upward along the inclined plane 36. This causes the lifting rod 42 to continue moving upward along the storage tank 41 under the elastic contraction of the support spring 44. As the lifting rod 42 moves upward, it simultaneously drives the sealing block 46 upward. When the sealing block 46 moves upward a second time, it blocks the passage of the water pipe 64 and opens the passage of the water guide pipe 71. At this time, the fluorinated liquid will flow from the storage tank 41 into the water guide pipe 71. Using the water distribution pipe 72 and connecting pipe 73, it will eventually be sprayed from the nozzle 74 onto the surface of the remote indicator and monitoring module components on the module board 2, thereby providing contact cooling and fire extinguishing for the module components. This cuts off the fire at its source, preventing the fire from spreading and causing serious damage to the equipment. Furthermore, the sprayed fluorinated liquid is insulating; while extinguishing the fire, direct contact with electrically powered components will not cause a short circuit. The extinguishing agent is chemically inert and does not react with components or circuit board materials such as copper, aluminum, and epoxy resin. After spraying, there is no need to disassemble and clean the machine, which can avoid damage to normal components inside the equipment. This allows other normal components to resume normal and timely operation, ensuring that the equipment can remotely indicate and monitor the power grid synchronous condenser in a timely manner. This avoids the problem of poor contact and heat dissipation obstruction of components caused by the residue of traditional fire extinguishing agents, which can lead to scrapping and unusability. This makes the remote indication and monitoring of the power grid synchronous condenser safer and more reliable. At the same time, when the smoke sensor 10 detects the spraying fire extinguishing, the external controller will also transmit a signal to the staff for timely maintenance. After the spraying fire extinguishing, the electric push cylinder 31 will drive the sealing plate 32 and the moving plate 34 to return to their original positions, allowing the lifting rod 42 and the sealing block 46 to move down again, so that the water pipe 71 is closed again and the water pipe 64 will circulate and cool again.

[0037] To address the technical issue that firefighting often requires separate fire-fighting equipment, leading to increased overall space and costs, such as... Figure 2 - Figure 9 As shown, the following preferred technical solutions are provided: The collection mechanism 8 includes a collection box 81 fixed to the bottom of the monitoring housing 1. A second water pump 82 is connected to one side of the collection box 81. The output end of the second water pump 82 is connected to a return pipe 83. The collection box 81 is connected to the heat sink 61 through the second water pump 82 and the return pipe 83. After the fluorinated liquid is sprayed for fire extinguishing, the settled fluorinated liquid will flow into the collection box 81 through the water inlet 30. The collected fluorinated liquid will be recycled back into the heat sink 61 using the second water pump 82 and the return pipe 83. At the same time, when the temperature inside the equipment rises abnormally but no fire occurs, the electric pusher cylinder 31 can also push the sealing plate 32 and the moving plate 34 forward a second time, so that the fluorinated liquid is sprayed out from the nozzle 74 and directly contacts the surface of the components to improve the cooling effect and ensure that the equipment can have good remote indication and monitoring accuracy. The system ensures the lifespan of the equipment. During normal operation, the fluorinated liquid circulates in the sealed circulation mechanism 6, allowing for long-term storage. The boiling point of the fluorinated liquid is above 100 degrees Celsius, far exceeding the temperature under abnormal conditions within the equipment. This minimizes the possibility of fluorinated liquid evaporation during spray cooling. After fire suppression spraying and during regular maintenance, personnel can replenish the fluorinated liquid in the heat dissipation box 61 by opening the mounting cover 40. The collection box 81 is used for recycling and circulating the fluorinated liquid, enabling the equipment to provide long-term and effective cooling and fire protection. Furthermore, the fluorinated liquid is used for circulating heat dissipation and can be directly sprayed in case of high temperatures or fire, eliminating the need for a separate fire suppression unit and achieving integrated heat dissipation and fire suppression, reducing the use of independent equipment.
