[0030] When performing a power-off process, the arc can be extinguished by filling a sufficient amount of oil medium inside the arc-extinguishing tube body 1. After long-term use, more impurities will be generated inside the oil medium in the middle of the arc-extinguishing tube body 1. At this time, a cleaning component can be used to clean the impurities stuck in the middle of the arc-extinguishing gasket 5, thereby reducing the accumulation of impurities in the middle of the arc-extinguishing gasket 5 and causing the elimination of the arc to be affected. The impurities at the bottom of the arc-extinguishing tube body 1 can be cleaned out to the outside through the cleaning component at the bottom of the inner side of the arc-extinguishing tube body 1, thereby reducing the situation where the arc elimination is affected by the large amount of impurities in the oil medium when using the oil medium to eliminate the arc.

[0031] The cleaning assembly includes a collar 9, a connecting rod 10, a cleaning brush 11, a slide groove 12, and a rotating rod 13. The collar 9 is rotatably connected to the middle of the rotating groove 8, and the collar 9 further rotates in the middle of the rotating groove 8. A plurality of connecting rods 10 are fixedly connected to the middle of the collar 9. A cleaning brush 11 is fixedly connected to the end of the connecting rod 10. The connecting rod 10 can support the cleaning brush 11. The cleaning brush 11 is slidably connected to the arc extinguishing gasket 5. A slide groove 12 is opened in the middle of the sliding rod 3, and a transmission assembly is arranged inside the slide groove 12.

[0032] When it is necessary to clean the impurities stuck in the middle of the arc extinguishing gasket 5, the transmission component can transfer kinetic energy to the rotating groove 8 through the slide groove 12, and then the ring 9 can be rotated in the middle of the rotating groove 8, and then the cleaning brush 11 can be supported by the connecting rod 10 to slide in the middle of the arc extinguishing gasket 5, and then the impurities stuck in the middle of the arc extinguishing gasket 5 can be cleaned by the cleaning brush 11, which can reduce the situation where impurities stuck in the middle of the arc extinguishing gasket 5 affect the elimination of the arc.

[0033] The transmission assembly includes a rotating rod 13, a transmission plate 14, and a twisting knob 15. The rotating rod 13 is rotatably connected inside the slide rod 3. Multiple groups of transmission plates 14 are fixedly connected to the end of the rotating rod 13. The transmission plates 14 are slidably connected to the slide grooves 12. The ends of the transmission plates 14 are fixedly connected to the inner wall of the sleeve 9. The end of the rotating rod 13 away from the transmission plates 14 is fixedly connected to the twisting knob 15. The transmission plates 14 can be rotated by turning the twisting knob 15. The twisting knob 15 is slidably connected to the slide rod 3.

[0034] When it is necessary to use the cleaning brush 11 to clean the impurities stuck in the middle of the arc extinguishing gasket 5, the rotating rod 13 can be rotated by turning the twist 15, and then the ring 9 can be rotated in the middle of the rotating groove 8 through the fixed connection between the transmission plate 14 and the ring 9, so that the cleaning brush 11 can be driven by the connecting rod 10 to slide in the middle of the arc extinguishing gasket 5, and then when there is no need to remove the oil medium inside the arc extinguishing tube body 1, the impurities stuck in the middle of the arc extinguishing gasket 5 can be cleaned, which can reduce the situation where the oil medium contains a large amount of impurities and affects the elimination of the arc.

[0035] The cleaning assembly includes a sweeping rod 22, a cleaning plate 23, a guide hole 24, and a rubber plug 25. The sweeping rod 22 is fixedly connected to the middle part of the support rod 6. The sweeping rod 22 can be driven to rotate inside the arc-extinguishing tube body 1 by rotating the support rod 6. The cleaning plate 23 is fixedly connected to the end of the sweeping rod 22. The cleaning plate 23 is slidably connected to the bottom of the arc-extinguishing tube body 1. The cleaning plate 23 can clean impurities at the bottom of the arc-extinguishing tube body 1. A guide hole 24 is opened at the bottom of the arc-extinguishing tube body 1. Impurities at the bottom of the arc-extinguishing tube body 1 can be cleaned to the outside through the guide hole 24. A rubber plug 25 is slidably connected inside the guide hole 24.

[0036] When the oil medium inside the arc-extinguishing tube body 1 contains a large amount of impurities, the rubber plug 25 can be taken out from the middle of the guide hole 24, and then the support rod 6 can be rotated, so that the cleaning plate 23 at the end of the sweeping rod 22 can clean the impurities accumulated at the bottom of the arc-extinguishing tube body 1, and then the impurities can be cleaned out of the interior of the arc-extinguishing tube body 1 through the guide hole 24, and then when it is necessary to replace the oil medium inside the arc-extinguishing tube body 1, the residual impurities inside the arc-extinguishing tube body 1 can be reduced, and the impact on the arc elimination can be reduced.

[0037] Example 2

[0038] like Figure 3 to Figure 6 As shown, a groove 16 is opened in the middle of the first disc 4, a retaining ring 17 is fixedly connected to the middle of the groove 16, a spring 19 is fixedly connected inside the retaining ring 17, a pressure block 20 is fixedly connected to the end of the spring 19, the pressure block 20 is slidably connected to the retaining ring 17, an elastic sheet 21 is fixedly connected to the end of the pressure block 20, and the elastic sheet 21 is slidably connected to the second disc 7.

[0039] When the end of the first disc 4 is brought into contact with the end of the second disc 7, the elastic sheet 21 can be brought into contact with the end of the second disc 7 first, and then the pressing block 20 can squeeze the spring 19 as the first disc 4 and the second disc 7 approach each other, so that the pressing block 20 can slowly enter the interior of the retaining ring 17. In the process of the elastic sheet 21 contacting the second disc 7, the oil medium between the contact surfaces will be gradually squeezed outward and discharged, so that after the first disc 4 and the second disc 7 are brought into contact, the poor contact caused by the presence of a large amount of oil medium in the middle can be reduced.

[0040] A conical pad 26 is fixedly connected to the bottom of the arc-extinguishing tube body 1, and the oil medium inside the arc-extinguishing tube body 1 can slide to the bottom of the arc-extinguishing tube body 1 through the conical pad 26. A plurality of guide grooves 27 are provided in the middle of the conical pad 26, and the guide grooves 27 can guide the oil medium in the middle of the conical pad 26. The side of the conical pad 26 is slidably connected to the cleaning plate 23, and at this time, the cleaning plate 23 can push and clean the oil medium sliding down from the middle of the conical pad 26.

[0041] When the oil medium inside the arc-extinguishing tube body 1 needs to be replaced, the conical pad 26 can be used to reduce the oil medium inside the arc-extinguishing tube body 1 from staying in the middle of the arc-extinguishing tube body 1. The guide groove 27 can make the oil medium flow to the bottom of the arc-extinguishing tube body 1 more quickly, and then the cleaning plate 23 can be rotated to discharge the oil medium to the outside through the guide hole 24. Therefore, when the oil medium inside the arc-extinguishing tube body 1 needs to be replaced, the completeness of the oil medium cleaning can be improved, and the oil medium containing impurities can be reduced from staying inside the arc-extinguishing tube body 1.

[0042] Example 3

[0043] like Figure 3 As shown, a connecting rod 30 is fixedly connected to the middle of the support rod 6. The rotation of the support rod 6 can drive the connecting rod 30 to rotate. A stirring blade 31 is fixedly connected to the end of the connecting rod 30 to stir the oil medium inside the arc-extinguishing tube body 1. A plurality of groups of circular holes 32 are opened in the middle of the stirring blade 31. The oil medium pushed by the middle of the stirring blade 31 can flow from the middle of the circular hole 32.

[0044] The oil medium inside the arc-extinguishing tube body 1 can be stirred by the rotation of the stirring blade 31, thereby reducing the occurrence of local overheating of the oil medium when the arc is extinguished. The circular hole 32 can reduce the thrust of the middle part of the stirring blade 31 when the stirring blade 31 is used to stir the oil medium inside the arc-extinguishing tube body 1, thereby increasing the stirring rate of the oil medium inside the arc-extinguishing tube body 1.

[0045] A hollow tube 28 is fixedly connected to the middle of the arc extinguishing gasket 5, which can absorb the heat generated by the arc elimination in the middle of the arc extinguishing gasket 5. A plurality of groups of heat dissipation fins 29 are fixedly connected to the middle of the arc extinguishing tube body 1. The ends of the hollow tube 28 are fixedly connected to the heat dissipation fins 29, and the heat dissipation fins 29 can transfer the heat in the middle of the hollow tube 28 to the outside.

[0046] When the arc extinguishing gasket 5 is used to extinguish the arc generated at the end of the first disk 4, the heat generated in the middle of the arc extinguishing gasket 5 can be absorbed by the hollow tube 28, and then the heat can be transferred to the heat dissipation fins 29 through the hollow tube 28, so that the arc extinguishing gasket 5 can be cooled and the over-temperature of the arc extinguishing gasket 5 can be reduced during the arc extinguishing process.

[0047] Example 4

[0048] like Figure 2 to Figure 7 As shown, an arc-shaped cavity 33 is provided at the bottom of the support rod 6, a screw rod 34 is rotatably connected to the middle of the arc-shaped cavity 33, a transmission rod 35 is fixedly connected to the end of the screw rod 34, a metal rod 36 is fixedly connected to the end of the transmission rod 35, and a clamping assembly is provided in the middle of the metal rod 36.

[0049] When the oil medium inside the arc-extinguishing tube body 1 needs to be replaced, the arc-extinguishing tube body 1 can be removed from the middle of the metal rod 36. At this time, the metal rod 36 can be rotated, and then the screw rod 34 can be rotated in the middle of the support rod 6 through the transmission action of the transmission pull rod 35, and then the support rod 6 can be taken out from the end of the metal rod 36. When the metal rod 36 is connected to the support rod 6, the support rod 6 and the metal rod 36 can be fixed by a clamping assembly.

[0050] A plurality of groups of arc-shaped spring pieces 37 are fixedly connected to the middle of the metal rod 36 , and a limiting piece 38 is fixedly connected to the end of the arc-shaped spring piece 37 . The limiting piece 38 is slidably connected to the arc-shaped cavity 33 .

[0051] When the screw rod 34 is placed inside the support rod 6 for rotation, the limiting plate 38 can be used to contact the bottom of the support rod 6, and then during the rotation of the screw rod 34, the arc-shaped spring piece 37 and the inner wall of the arc-shaped cavity 33 can gradually fit together, thereby improving the stability of the connection between the metal rod 36 and the support rod 6 and reducing the separation between the support rod 6 and the metal rod 36 during operation.

[0052] When power is cut off, the arc can be extinguished by filling a sufficient amount of oil medium inside the arc extinguishing tube body. After long-term use, more impurities will be generated inside the oil medium in the middle of the arc extinguishing tube body. At this time, a cleaning component can be used to clean the impurities adhering to the middle of the arc extinguishing gasket, thereby reducing the accumulation of impurities in the middle of the arc extinguishing gasket and the impact on the elimination of the arc. The impurities at the bottom of the arc extinguishing tube body can be cleaned out to the outside through the cleaning component at the bottom of the inner side of the arc extinguishing tube body, thereby reducing the impact on the elimination of the arc caused by the large amount of impurities in the oil medium when the oil medium is used to eliminate the arc. When it is necessary to clean the impurities adhering to the middle of the arc extinguishing gasket, the transmission component can transfer the impurities to the rotating groove through the slide groove. Kinetic energy, and then the sleeve ring can be rotated in the middle of the rotating groove, and then the cleaning brush can be driven by the supporting effect of the connecting rod to slide in the middle of the arc extinguishing gasket, and then the impurities stuck in the middle of the arc extinguishing gasket can be cleaned by the cleaning brush, which can reduce the situation where the impurities stuck in the middle of the arc extinguishing gasket affect the elimination of the electric arc. When it is necessary to use the cleaning brush to clean the impurities stuck in the middle of the arc extinguishing gasket, the rotating rod can be rotated by twisting, and then the sleeve ring can be rotated in the middle of the rotating groove through the fixed connection between the transmission plate and the sleeve ring, so that the cleaning brush can be driven by the connecting rod to slide in the middle of the arc extinguishing gasket, and then when there is no need to take out the oil medium inside the arc extinguishing tube body, the impurities stuck in the middle of the arc extinguishing gasket can be cleaned, which can reduce the oil medium. The medium contains a large amount of impurities and affects the elimination of the arc. When the oil medium inside the arc-extinguishing tube body contains more impurities, the rubber plug can be taken out from the middle of the guide hole, and then the support rod can be rotated, and then the cleaning plate at the end of the sweeping rod can clean the impurities accumulated at the bottom of the arc-extinguishing tube body, and then the impurities can be cleaned out of the interior of the arc-extinguishing tube body through the guide hole, and then when it is necessary to replace the oil medium inside the arc-extinguishing tube body, the situation of residual impurities in the arc-extinguishing tube body can be reduced, and then the situation of affecting the arc elimination can be reduced. When the end of the first disc is in contact with the end of the second disc, the elastic sheet can be first in contact with the end of the second disc, and then in the process of the first disc and the second disc approaching each other, the pressing block can be pressed on the elastic sheet. The spring is squeezed, so that the pressure block can slowly enter the interior of the clamping ring. In the process of the elastic sheet and the second disc contacting, the oil medium between the contact surfaces will be gradually squeezed outward and discharged, so that after the first disc and the second disc are in contact, the poor contact caused by the presence of a large amount of oil medium in the middle can be reduced. When it is necessary to replace the oil medium inside the arc-extinguishing tube body, the conical pad can be used to reduce the oil medium inside the arc-extinguishing tube body from staying in the middle of the arc-extinguishing tube body. The guide groove can make the oil medium flow to the bottom of the arc-extinguishing tube body more quickly, and then the cleaning plate can be rotated to discharge the oil medium to the outside through the guide hole, so that when it is necessary to replace the oil medium inside the arc-extinguishing tube body,The completeness of cleaning the oil medium can be improved, and the situation that the oil medium containing impurities stays in the arc-extinguishing tube body can be reduced. The oil medium in the arc-extinguishing tube body can be stirred by the rotating action of the stirring blade, and the local overheating of the oil medium can be reduced when the arc is extinguished. The role of the circular hole can reduce the thrust of the middle part of the stirring blade when the stirring blade is used to stir the oil medium in the arc-extinguishing tube body, and the stirring rate of the oil medium in the arc-extinguishing tube body can be improved. When the arc generated at the end of the first disc is extinguished by the arc-extinguishing gasket, the heat generated in the middle part of the arc-extinguishing gasket can be absorbed by the hollow tube, and then the heat can be transferred to the heat dissipation fins through the hollow tube, and the arc-extinguishing gasket can be heat-dissipated, reducing the time required for arc extinguishing. In addition to the situation that the temperature of the arc-extinguishing gasket is too high during the process, when the oil medium inside the arc-extinguishing tube body needs to be replaced, the arc-extinguishing tube body can be removed from the middle of the metal rod. At this time, the metal rod can be rotated, and then the screw rod can be rotated in the middle of the support rod through the transmission action of the transmission pull rod, and then the support rod can be taken out from the end of the metal rod. When the metal rod and the support rod are connected, the support rod and the metal rod can be fixed by the clamping assembly. When the screw rod is placed inside the support rod and rotated, the limit plate can be used to contact the bottom of the support rod. Then, during the rotation of the screw rod, the arc-shaped spring piece and the inner side wall of the arc-shaped cavity can gradually fit each other, thereby improving the stability of the connection between the metal rod and the support rod and reducing the separation of the support rod and the metal rod during the working process.
