[0020] The present invention has the following beneficial effects:

[0021] When the gas flows out to the discharge pipe through the connecting pipe, the inner wall of the pushing pipe and the outer wall of the discharge pipe are slidably sleeved, the column in the inner wall of the pushing pipe and the inner cavity of the discharge pipe are slidably sleeved, and a limit plate is provided on the outer edge of the column in the inner wall of the pushing pipe. The limit plate and the inner wall of the limit slide groove are slidably sleeved, so that the gas can push the pushing pipe to move downward. When the top of the column in the inner wall of the pushing pipe is located below the discharge connection hole, the gas one-way valve is used to communicate with the discharge connection hole through the guide groove. The gas one-way valve is a one-way valve, and its flow direction is from the discharge connection hole to the gas one-way valve, so that the gas is discharged through the gas one-way valve. At this time, the gas does not flow through the filler located in the inner cavity of the observation sealing pipe, thereby reducing the absorption energy efficiency of the filler and increasing its service life.

[0022] A screw rod is connected through the inner wall of the internal thread groove, so that when the push tube moves downward, the screw rod rotates, and then the screw rod drives the filter assembly to rotate through the one-way clutch bearing;

[0023] The top of the peristaltic pump shaft and the outer ring structure of the one-way clutch bearing are fixedly assembled, and the inner ring structure of the one-way clutch bearing and the screw are fixedly assembled. When the push tube moves downward, the screw is rotated, and then the screw drives the peristaltic pump shaft to rotate through the one-way clutch bearing. The peristaltic hose is arranged at the outer edge of the peristaltic rotating shaft, and the isolation plate separates the inner cavity of the filter oil bin into a filter bin and a storage bin. The filter bin and the storage bin are connected through the peristaltic hose. The contact surface of the isolation shell and the isolation plate is sealed and connected, so that the filtered oil located in the storage bin is transmitted to the filter bin through the peristaltic pump composed of the peristaltic hose, the isolation shell, the peristaltic pump shaft, the fixed plate 2, and the peristaltic rotating shaft, and the filtered oil in the filter bin is filtered to the storage bin through the filter plate, thereby realizing the filtering effect of the filtered oil;

[0024] By locating both ends of the gas flow groove at the top outer wall and inner wall of one side of the filter bin, the filter bin is connected with the inner cavity of the cleaning component through the gas flow groove, and the filter oil in the storage bin is reduced from absorbing too much dust.

[0025] The single-side filter plate is divided into a sealing surface and a filtering surface with the isolation plate as the center line. The filtering surface is located on one side of the storage bin, so that the air entering the inner cavity of the observation sealing tube can be further purified through the filtering component;

[0026] Once the gas is discharged through the gas one-way valve, the push tube stops moving downward. At the same time, the volume of the oil decreases due to the spring push and the temperature of the transformer oil decreases. The air in the transformer main body oil pillow is expanded and the pressure decreases. The pressure in the oil pillow sucks in air through the discharge pipe, causing the push tube to move upward. The one-way clutch bearing is used to make the push tube move upward to drive the screw rod to rotate in the opposite direction, while the peristaltic pump shaft can remain stationary.

[0027] The inner wall of one end of the support frame body 2 away from the piston and the bottom end of the screw rod are threadedly connected, and the fixed shaft and the support bottom plate are used for fixed assembly. The piston and the air pipe are slidably sleeved, so that when the screw rod rotates clockwise, the support frame body 2 slides downward along the inner cavity of the air pipe, so that the gas in the inner cavity of the air pipe is discharged through the filter membrane, thereby achieving the effect of cleaning the blockage of the filter membrane. At the same time, the rotating end of the annular motor and the filter membrane are fixedly assembled, and the main body end of the annular motor and the inner wall of the fixed shell are fixedly assembled, so that the annular motor drives the filter membrane to rotate, so that the air pipe can clean the filter membranes at different positions;

[0028] When the transformer oil is cooled, the volume of the oil decreases, the air in the transformer main body oil pillow is expanded, the pressure decreases, and the pressure in the oil pillow sucks in air through the discharge pipe, causing the push tube to move upward. The one-way clutch bearing is used to move the push tube upward to drive the screw rod to rotate in the opposite direction. The screw rod and the support frame are threadedly connected to each other, so that the support frame drives the piston to move upward along the air pipe direction, and then the piston and the air pipe can be repeatedly rotated by the screw rod to clean the filter membrane.

The main body and the rotating ring rotate through the principle of magnetic cutting, and the inner wall of the rotating ring is fixed to the outer edge of the filter membrane 12104.

[0068] Among them, the inner wall of one end of the support frame body 12108 away from the piston 12107 is threadedly connected to the bottom end of the screw rod 1218, the rotating end of the annular motor 12110 and the filter membrane 12104 are fixedly assembled, the main body end of the annular motor 12110 and the inner wall of the fixed shell 12101 are fixedly assembled, and the fixed shaft 12109 and the support base plate 12102 are fixedly assembled.

[0069] In the above structure, the inner wall of one end of the support frame 12108 away from the piston 12107 is threadedly connected with the bottom end of the screw rod 1218, and the fixed shaft 12109 and the support bottom plate 12102 are used for fixed assembly. The piston 12107 and the air pipe 12106 are slidably sleeved, so that when the screw rod 1218 rotates clockwise, the support frame 12108 slides downward along the inner cavity of the air pipe 12106, so that the gas in the inner cavity of the air pipe 12106 is discharged through the filter membrane 12104, thereby realizing the effect of cleaning the blockage of the filter membrane 12104, and at the same time utilizing the annular motor 12110 The rotating end and the filter membrane 12104 are fixedly assembled, and the main end of the annular motor 12110 and the inner wall of the fixed shell 12101 are fixedly assembled, so that the annular motor 12110 drives the filter membrane 12104 to rotate, so that the air pipe 12106 can clean the filter membranes 12104 at different positions, and the screw rod 1218 is rotated counterclockwise to make the support frame body 12108 drive the piston 12107 to move upward along the direction of the air pipe 12106, so that the piston 12107 and the air pipe 12106 can be repeatedly rotated by the screw rod 1218 to clean the filter membrane 12104.

[0070] Working principle,

[0071] By setting the installation pulley block 2, the equipment can be moved between the installation pulley block 2 and the equipment installation frame during installation, thereby increasing the convenience of equipment installation;

[0072] Since the temperature of the transformer oil in the transformer body 1 changes, when the temperature of the transformer oil rises, the volume of the oil increases, the air in the oil conservator of the transformer body 1 is compressed, the pressure increases, and part of the air in the oil conservator will be discharged through the respirator 12;

[0073] When the gas flows out to the discharge pipe 1203 through the connecting pipe 1201, the inner wall of the push pipe 1213 and the outer wall of the discharge pipe 1203 are slidably connected, the column in the inner wall of the push pipe 1213 and the inner cavity of the discharge pipe 1203 are slidably connected, and a limit plate is provided on the outer edge of the column in the inner wall of the push pipe 1213. The limit plate and the inner wall of the limit slide groove 1217 are slidably connected, so that the gas can push the push pipe 1213 to move downward, and the top of the column in the inner wall of the push pipe 1213 is pushed downward. When the gas is located below the discharge connection hole 1212, the gas one-way valve 1204 is used to communicate with the discharge connection hole 1212 through the guide groove 1211. The gas one-way valve 1204 is a one-way valve, and its flow direction is from the discharge connection hole 1212 to the gas one-way valve 1204, so that the gas is discharged through the gas one-way valve 1204. At this time, the gas does not flow through the filler located in the inner cavity of the observation sealing tube 1206, thereby reducing the absorption energy efficiency of the filler and increasing its service life;

[0074] A screw rod 1218 is threadedly connected to the inner wall of the internal thread groove 1215, so that when the push tube 1213 moves downward, the screw rod 1218 rotates, and then the screw rod 1218 drives the filter assembly 1209 to rotate through the one-way clutch bearing 1220;

[0075] The top of the peristaltic pump shaft 12098 is fixedly assembled with the outer ring structure of the one-way clutch bearing 1220, and the inner ring structure of the one-way clutch bearing 1220 is fixedly assembled with the screw 1218. When the push tube 1213 moves downward, the screw 1218 is rotated, and then the screw 1218 drives the peristaltic pump shaft 12098 to rotate through the one-way clutch bearing 1220. The peristaltic hose 12095 is arranged at the outer edge of the peristaltic shaft 120910, and the isolation plate 12093 separates the inner cavity of the filter oil tank 12091 into a filter tank. The filter bin and the storage bin are connected through a peristaltic hose 12095, and the contact surfaces of the isolation shell 120912 and the isolation plate 12093 are sealed and connected, so that the filtered oil in the storage bin is transmitted to the filter bin through the peristaltic pump composed of the peristaltic hose 12095, the isolation shell 120912, the peristaltic pump shaft 12098, the second fixing plate 12099, and the peristaltic rotating shaft 120910, and the filter plate 12097 is set, so that the filtered oil in the filter bin is filtered through the filter plate 12097 to the storage bin, thereby achieving the filtering effect of the filtered oil;

[0076] By locating both ends of the gas flow slot 12092 at the top outer wall and inner wall of one side of the filter bin, the filter bin is connected with the inner cavity of the cleaning component 1210 through the gas flow slot 12092, and the filter oil in the storage bin is prevented from absorbing too much dust.

[0077] The single-side filter plate 1208 is divided into a sealing surface and a filtering surface with the isolation plate 12093 as the center line. The filtering surface is located on one side of the storage bin, so that the air entering the inner cavity of the observation sealing tube 1206 is further purified through the filter assembly 1209;

[0078] After the gas is discharged through the gas one-way valve 1204, the push tube 1213 stops moving downward. At the same time, when the spring 1219 pushes and the transformer oil cools down, the volume of the oil decreases, the air in the oil pillow of the transformer body 1 is expanded, the pressure decreases, and the pressure in the oil pillow sucks air through the discharge pipe 1203, so that the push tube 1213 moves upward. When the push tube 1213 moves upward and drives the screw rod 1218 to rotate in the opposite direction by using the one-way clutch bearing 1220, the peristaltic pump shaft 12098 can remain stationary.

[0079] The inner wall of one end of the support frame 12108 away from the piston 12107 is threadedly connected with the bottom end of the screw rod 1218, and the fixed assembly is performed by the fixed shaft 12109 and the support bottom plate 12102. The piston 12107 and the air pipe 12106 are slidably sleeved, so that when the screw rod 1218 rotates clockwise, the support frame 12108 slides downward along the inner cavity of the air pipe 12106, so that the gas in the inner cavity of the air pipe 12106 is discharged through the filter membrane 12104, thereby achieving the effect of cleaning the blockage of the filter membrane 12104. At the same time, the rotating end of the annular motor 12110 and the filter membrane 12104 are fixedly assembled, and the main end of the annular motor 12110 and the inner wall of the fixed shell 12101 are fixedly assembled, so that the annular motor 12110 drives the filter membrane 12104 to rotate, so that the air pipe 12106 can clean the filter membranes 12104 at different positions;

[0080] When the transformer oil is cooled, the volume of the oil decreases, the air in the oil pillow of the transformer body 1 is expanded, the pressure decreases, and the pressure in the oil pillow draws in air through the discharge pipe 1203, causing the push tube 1213 to move upward. The one-way clutch bearing 1220 is used to move the push tube 1213 upward to drive the screw rod 1218 to rotate in the opposite direction. The screw rod 1218 and the second support frame 12108 are threadedly connected to drive the piston 12107 to move upward in the direction of the air pipe 12106, so that the piston 12107 and the air pipe 12106 can be cleaned through the repeated rotation of the screw rod 1218.
