Multiple three-way valves are movably connected to the left surface of the exhaust pipe. A rotating block is fixedly connected to the outer side of each three-way valve. An air injection assembly is installed so that when a fault occurs inside the oil-immersed transformer, the push rod two moves to the left, causing the triangular protrusion to drive the rotating block to rotate. This allows the inert gas in the high-pressure gas storage tank to be quickly injected into the oil-immersed transformer through the exhaust pipe, thus isolating the interior from the air, preventing the fire from spreading, and protecting the safety of the transformer's internal components as much as possible.

[0009] Preferably, the number of fixing columns is two, each of the fixing columns is symmetrically distributed about the centerline of the oil-immersed transformer, the number of nozzles is five, the number of triangular protrusions is five, the number of three-way valves is five, and the number of rotating blocks is five.

This prevents secondary damage to the transformer's interior from the burning cooling oil, ensuring a more reliable mechanical structure and preventing electronic control component failure due to fire.

[0015] The transformer body's rapid oil drainage device works by increasing the internal pressure of hydraulic block one, which, in conjunction with heat-resistant conduit two, hydraulic block three, push rod two, triangular protrusion, and rotating block, causes the rotating block to drive the three-way valve to rotate, allowing inert gas from the high-pressure gas storage tank to be injected into the oil-immersed transformer. This improves the oil drainage efficiency inside the oil-immersed transformer and simultaneously isolates the air to prevent the spread of fire.

[0016] The transformer body's rapid oil drainage device, when push rod two moves to the left, works in conjunction with the insulating push rod, conductive slide rod, alarm housing, PCB board, and conductive interface to close the two conductive interfaces, forming a closed circuit, thereby activating the alarm. This allows the device to issue an alarm without relying on sensors, saving costs and making it more reliable. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1, please refer to Figures 1-4 A transformer body rapid oil drainage device, comprising: The base plate 100 has a support base 200 on its top. An oil-immersed transformer 300 is fixedly connected to the top of the support base 200. A circulating oil draining device 400 with oil drainage and impurity removal function is set on the right side of the oil-immersed transformer 300. A first oil storage tank 500 and a second oil storage tank 600 are set on the outside of the circulating oil draining device 400. The first oil storage tank 500 and the second oil storage tank 600 enable the equipment to automatically replace the cooling oil under normal conditions, thereby ensuring normal operation of the equipment. An oil filling port 700 is opened on the top of the oil-immersed transformer 300, which allows the cooling oil inside the oil-immersed transformer 300 to be added through the oil filling port 700. A lifting ring 800 is fixedly connected to the top of the oil-immersed transformer 300, which makes the installation of the oil-immersed transformer 300 more convenient. A vent 901 is fixedly connected to the top of the oil-immersed transformer 300. The outer side of the vent 901 is fixedly connected to a fixed circular shell 903 via a fixing rod 902. A second fixed circular shell 906 is fixedly connected inside the first fixed circular shell 903. A push rod 905 is movably connected inside the second fixed circular shell 906. A vent block 904 is fixedly connected to the bottom of the push rod 905. The vent block 904 is installed to keep the inside of the oil-immersed transformer 300 sealed and to prevent air from flowing back into the oil-immersed transformer. Inside the transformer 300, a spring 907 is fixedly connected to the outer side of push rod 905. The spring 907 is set so that the vent block 904 blocks the vent 901 to maintain a seal. A push block 908 is fixedly connected to the top of push rod 905. A hydraulic block 909 is movably connected to the top of push block 908. The top of hydraulic block 909 is fixedly connected to the top of fixed round shell 906 through fixed bracket 910. Hydraulic block 909 is movably connected to quick oil drain pipe 915 through transmission component. The transmission components include a heat-resistant conduit 911, a hydraulic block 912, a rotating push block 913, and a valve 914. The bottom of the oil-immersed transformer 300 is fixedly connected to a quick-drain oil pipe 915, and the bottom of the quick-drain oil pipe 915 is fixedly connected to a closed oil tank. The top of the hydraulic block 909 is fixedly connected to one end of the heat-resistant conduit 911, and the other end of the heat-resistant conduit 911 is fixedly connected to the top of the hydraulic block 912. The heat-resistant conduit 911 is set so that the interior of the hydraulic block 909 communicates with the interior of the hydraulic block 912. The side of the hydraulic block 912 is fixedly connected to the outside of the quick-drain oil pipe 915 through a fixed block. The bottom of the hydraulic block 912 is movably connected to a rotating push block 913, and the rear side of the rotating push block 913 is fixedly connected to a valve 914. There are two vent ports 901, each vent port 901 is symmetrically distributed about the centerline of the oil-immersed transformer 300, there are eight fixing rods 902, four fixing rods 902 form a group, there are two fixing round shells 903, there are two vent plugs 904, there are two push rods 905, there are two fixing round shells 906, there are two springs 907, there are two push blocks 908, and there are two hydraulic blocks 909. The system is equipped with a vent 901 and a quick-drain oil pipe 915. When a fire occurs inside the oil-immersed transformer 300, the high temperature causes some of the cooling oil to vaporize, increasing the internal pressure of the transformer 300. This allows the internal steam to be discharged through the vent 901, preventing the transformer 300 from exploding due to excessive internal pressure. Simultaneously, the valve 914 is opened by the internal pressure of the hydraulic block 909, allowing the cooling oil inside the transformer 300 to drain into the sealed oil tank at the bottom through the quick-drain oil pipe 915 by its own gravity. This prevents the burning cooling oil from causing secondary damage to the internal components of the transformer 300, thus achieving the purpose of rapid oil drainage and fire extinguishing.

[0021] When a fault occurs inside the oil-immersed transformer 300 during operation, the high temperature of local components causes some of the cooling oil inside the transformer 300 to vaporize. The vaporized cooling oil is discharged to the outside through the vent 901, making the internal pressure of the oil-immersed transformer 300 controllable. This prevents the transformer 300 from exploding due to high pressure. The vent block 904 is moved upward by the gas, causing the push block 908 to move upward. This increases the internal pressure of the right hydraulic block 909, which is then transmitted to the hydraulic block 912 through the heat-resistant conduit 911. This increases the internal pressure of the hydraulic block 912, causing the rotating push block 913 to move outward. This causes the valve 914 to rotate, allowing the cooling oil inside the oil-immersed transformer 300 to be directly discharged into the sealed oil tank through the quick drain pipe 915. This prevents the cooling oil from burning and causing greater losses. Under high-temperature conditions, the entire equipment does not involve electronic controllers, making the fire protection effect of the equipment more reliable.

[0022] Example 2, please refer to Figures 1-6 Based on Embodiment 1, the gas injection assembly 1000 includes a second heat-resistant conduit 1001, a fixed column 1002, a high-pressure gas storage tank 1003, an exhaust pipe 1004, a second fixing frame 1005, a third hydraulic block 1006, a second push rod 1007, a triangular protrusion 1008, and a rotating block 1009. The top of the left-side first hydraulic block 909 is fixedly connected to one end of the second heat-resistant conduit 1001, and the other end of the second heat-resistant conduit 1001 is fixedly connected to the right side of the third hydraulic block 1006. The second heat-resistant conduit 1001 is provided so that the interior of the first hydraulic block 909 communicates with the interior of the third hydraulic block 1006. The top of the oil-immersed transformer 300 is fixedly connected to the high-pressure gas storage tank 1003 through the fixed column 1002. The high-pressure gas storage tank 1003 is provided to make the interior of the high-pressure gas storage tank 1003 inert. Gas can be quickly injected into the oil-immersed transformer 300. A vent pipe 1004 is fixedly connected to the rear side of the high-pressure gas storage tank 1003. Multiple nozzles are fixedly connected to the bottom of the vent pipe 1004. The nozzles are set to make the inert gas in the vent pipe 1004 more evenly discharged into the oil-immersed transformer 300. The right side of the vent pipe 1004 is fixedly connected to the top of the oil-immersed transformer 300 through the fixing bracket 2 1005. The left side of the hydraulic block 3 1006 is movably connected to the push rod 2 1007. The bottom of the push rod 2 1007 is slidably connected to the top of the oil-immersed transformer 300. Multiple triangular protrusions 1008 are fixedly connected to the top of the push rod 2 1007. Multiple three-way valves are movably connected to the left surface of the vent pipe 1004. A rotating block 1009 is fixedly connected to the outside of the three-way valve. There are two fixed columns 1002, each symmetrically distributed about the centerline of the oil-immersed transformer 300; there are five nozzles; there are five triangular protrusions 1008; there are five three-way valves; and there are five rotating blocks 1009. The gas injection assembly 1000 is installed so that when a fault occurs inside the oil-immersed transformer 300, the push rod 1007 moves to the left, causing the triangular protrusion 1008 to drive the rotating block 1009 to rotate. This allows the inert gas in the high-pressure gas storage tank 1003 to be quickly injected into the oil-immersed transformer 300 through the exhaust pipe 1004, thus isolating the interior from the air, preventing the fire from spreading, and protecting the safety of the transformer's internal components as much as possible.

[0023] In use, based on Example 1, when the internal pressure of the left hydraulic block 909 increases, the internal pressure of the left hydraulic block 909 is transmitted to the internal pressure of the hydraulic block 1006 through the heat-resistant conduit 1001, causing the internal pressure of the hydraulic block 1006 to increase. This causes the push rod 1007 to move to the left, and the triangular protrusion 1008 on the push rod 1007 drives the rotating block 1009 to rotate, thereby opening the five three-way valves. This allows the inert gas inside the high-pressure gas tank 1003 to be quickly injected into the oil-immersed transformer 300 through the exhaust pipe 1004, thus isolating the interior from the air and preventing the fire from spreading. This protects the safety of the internal components of the transformer as much as possible. At the same time, the injection of inert gas into the oil-immersed transformer 300 improves the efficiency of cooling oil drainage.

[0024] Example 3, please refer to Figures 1-8 Based on Embodiment 1 and Embodiment 2, the alarm triggering component 1100 includes an insulating push rod 1101, a conductive slide rod 1102, an alarm housing 1103, a PCB board 1104, and a conductive interface 1105. The insulating push rod 1101 is fixedly connected to the left side of the push rod 1007. The insulating push rod 1101 is set to prevent the circuit of the PCB board 1104 from being affected by other components and to avoid false alarms. The conductive slide rod 1102 is fixedly connected to the left side of the insulating push rod 1101. The alarm housing 1103 is fixedly connected to the top of the oil-immersed transformer 300. The PCB board 1104 is fixedly connected inside the alarm housing 1103. The conductive interface 1105 is fixedly connected to the surface of the PCB board 1104. There are two conductive interfaces 1105. The spacing between the two conductive interfaces 1105 is the same as the width of the conductive slide bar 1102; The alarm triggering component 1100 is set up so that the push rod 1007 drives the conductive slide rod 1102 to move to the left, so that the conductive interface 1105 contacts the conductive slide rod 1102, thereby realizing the circuit closed loop on the PCB board 1104, so that the alarm can sound an alarm without the need for a sensor, saving costs.

[0025] In use, based on Embodiment 1 and Embodiment 2, when push rod 2 1007 moves to the left, insulating push rod 1101 moves to the left, causing insulating push rod 1101 to drive conductive slide rod 1102 to move to the left, so that the inner side of conductive interface 1105 contacts the outer wall of conductive slide rod 1102, thereby closing the circuit on PCB board 1104, thus activating the alarm and enabling operators to receive a fire signal. This avoids the damage to the circuit of traditional sensors under high-temperature conditions, thus preventing greater damage to the equipment, saving costs, and making the equipment more reliable.
