When the second slider 51 slides linearly and reciprocally, the L-shaped frame 511 fixedly connected to the second slider 51 moves synchronously, and then the latch 512 fixedly connected to the L-shaped frame 511 moves synchronously, at this time, the latch 512 drives the cam 612 to slide on the spiral tube 611, so that the spiral tube 611 generates vibration, the vibration generated by the empty spiral tube 611 is transmitted to the return tube 61, the return tube 61 vibrates to shake down impurities such as dust attached to the return tube 61, and the transformer oil flowing in the return tube 61 can be further cooled.

When the second slider 51 slides, the rack 72 fixedly connected to the second slider 51 slides synchronously, because the rack 72 is meshed with the second gear ring 7, and then the rack 72 sliding in a reciprocating manner can drive the second gear ring 7 to rotate in a reciprocating manner, because the one-way bearing 71 is arranged, the second gear ring 7 can only rotate on the screw pump shaft 621 in a one-way manner, and further, the second gear ring 7 rotating when the second gear ring 7 rotates on the screw pump shaft 621 cannot drive the screw pump shaft 621 to rotate, and when the second gear ring 7 does not rotate relative to the screw pump shaft 621, the second gear ring 7 driven by the rack 72 can drive the screw pump shaft 621 to rotate, at the moment, the screw pump shaft 621 can rotate, so that the transformer oil in the transformer box 1 is conveyed into the cooling box 6 through the suction pipe 62, and the cooling effect is improved.
The working principle of the first embodiment of the application is as follows: the transmission temperature oil level temperature controller utilizing the magnetic coding angular displacement chip controls the number of positive and negative rotation turns of the magnetic coding motor 33 by writing an encoder on the magnetic coding motor 33 during use, the rotating shaft 34 on the magnetic coding motor 33 rotates when the magnetic coding motor 33 is in a working state, so that the first gear 341 on the rotating shaft 34 synchronously rotates along with the rotating shaft 34, the first gear 341 is meshed with the teeth 32 on the mounting bar 3, so that the first gear 341 rolls on the mounting bar 3 when rotating, the mounting block 31 linearly slides on the mounting bar 3, the first gear 341 reciprocally rolls on the mounting bar 3, so that the mounting block 31 linearly reciprocally slides on the mounting bar 3, and the probe 343 on the rotating shaft 34 synchronously moves along with the rotating shaft 34, so that the probe 343 can detect the temperature of the transformer oil in a larger range in the transformer box 1, and the lead 342 reversely rotates under the states of the rotating shaft 34 and the rotating shaft 34 alternately appears in a state of being accommodated in the rotating shaft 34 and being released from the rotating shaft 34 So that the wire 342 can be always in a tensed state, and the wire 342 is prevented from being wound by a component outside the rotating shaft 34 to cause tension fracture.
When the mounting block 31 makes a linear reciprocating sliding motion, the mounting handle 311 on the mounting block 31 and the mounting block 31 move synchronously, and then the first connecting rod 312 rotatably connected to the mounting handle 311 and the first slide block 42 is pushed by the mounting block 31 to swing around the joint of the first connecting rod 312 and the first slide block 42, the first slide block 42 is gradually pushed by the first connecting rod 312 swinging in the vertical direction to slide along the first slide base 4 in the process that the mounting block 31 gradually approaches the first slide base 4, the first slide block 42 slides to the maximum stroke when the first connecting rod 312 is parallel to the first slide base 4, and then the first slide block 42 slides to the original position in the process that the mounting block 31 gradually leaves the first slide base 4, and as the mounting block 31 makes a linear reciprocating motion, the first slide block 42 slides in the first slide base 4 in a reciprocating manner, and then the spoiler 421 fixedly connected to the first slide block 42 moves synchronously with the first slide block 42, therefore, the movement of the spoiler 421 enables the transformer oil inside the transformer tank 1 to be disturbed so that the transformer oil flows in the transformer tank 1, and the transformer oil can uniformly absorb the heat generated in the transformer tank 1.
When the second slider 51 moves, the L-shaped rod 631 moves synchronously and is fixedly connected to the second slider 51, and then the mounting plate 632 on the L-shaped rod 631 moves synchronously along with the second slider 51, and at this time, the two wedge blocks 633 on the mounting plate 632 alternately push teeth on the first toothed ring 63, so that the first toothed ring 63 rotates, and then the screw pump shaft 621 rotates, and the transformer oil in the transformer box 1 is conveyed into the cooling box 6 through the suction pipe 62, thereby increasing the cooling effect.
The cooling box 6 is arranged outside the transformer box 1, so that the transformer oil in the cooling box 6 outside the transformer box 1 can be naturally cooled, when the transformer oil with higher temperature enters the cooling tank 6, the transformer oil which is remained in the cooling tank 6 and is cooled is squeezed by the transformer oil with higher temperature and flows out through the return pipe 61, the flowing transformer oil enters the spiral pipe 611 again and is discharged into the transformer tank 1 from the spiral pipe 611 to cool the transformer tank 1, when the spoiler 421 slides linearly, the second link 422 connected to the spoiler 421 swings around the connection point with the second slider 51, the spoiler 421 moving linearly and reciprocally pushes and pulls the second link 422 to swing, and the swinging second link 422 continuously pushes the second slider 51 to linearly slide back and forth in the second slider 5, the piston cylinder 52, which is fixedly connected to the second carriage 5, then slides along the second slide 51.
When the temperature in the transformer tank 1 is higher than sixty degrees, the expansion rate of the air in the piston cylinder 52 is increased, at this time, the expanded air pushes the piston plate 522 to slide, and further, the piston rod 521 extends out from the piston cylinder 52, at this time, the total length of the piston rod 521 and the second slider 51 is increased, further, when the second slider 51 is farthest from the pressure sensitive switch 643, the piston rod 521 can also contact the pressure sensitive switch 643, the reciprocating second slider 51 and the stationary pressure sensitive switch 643 jointly press the piston rod 521, so that the piston rod 521 slides against the resistance of the expanded air in the piston cylinder 52, when the pressure sensitive switch 643 is pressed by the piston rod 521, the second motor 64 operates, further, the vane 641 rotates at high speed to blow air to the cooling tank 6, so that the transformer oil in the cooling tank 6 can be cooled rapidly, and the expanded air in the piston cylinder 52 recovers after the temperature of the transformer oil is reduced, at this time, the piston rod 521 no longer contacts the pressure sensitive switch 643, and the second motor 64 stops operating.
When the second slider 51 slides linearly and reciprocally, the L-shaped frame 511 fixedly connected to the second slider 51 moves synchronously, and then the latch 512 fixedly connected to the L-shaped frame 511 moves synchronously, at this time, the latch 512 drives the cam 612 to slide on the spiral tube 611, so that the spiral tube 611 generates vibration, the vibration generated by the empty spiral tube 611 is transmitted to the return tube 61, the return tube 61 vibrates to shake down impurities such as dust attached to the return tube 61, and the transformer oil flowing in the return tube 61 can be further cooled.
