The top of the movable tube 506 is fixedly connected with an air blowing tube 507 connected thereto, the outer movable sleeve of the movable tube 506 is provided with a movable ring 508, the outer ring of the movable ring 508 is fixedly connected with a toggle rod 509, the outer movable sleeve of the toggle rod 509 is provided with a torsion plate 510, the torsion plate 510 is fixedly connected with a screw rod 511 on the side away from the movable tube 506, the screw rod 511 is fixedly connected with a double-axis motor 512 on the end away from the torsion plate 510, and the double-axis motor 512 is fixedly connected to the water guide plate 4, and the double-axis motor The output shaft of the motor 512 at one end away from the screw 511 is fixedly connected to the transmission shaft 513, and the end of the transmission shaft 513 away from the dual-axis motor 512 is fixedly connected to the driving bevel gear 514. The air pump 502 sends gas into the coil 503, and the coil 503 is immersed in water. Ice cubes are added to the water tank 3 to lower the water temperature. In this way, after heat exchange through the coil 503, the cold air will enter the fixed pipe 504 and the movable pipe 506, and finally enter the blowing pipe 507, and the blowing pipe 507 is used to heat the transformer body 1. To blow cold air, the dual-axis motor 512 drives the screw 511 to rotate, and the rotation of the screw 511 will drive the torsion plate 510 to rotate, and the torsion plate 510 will drive the toggle rod 509 and the movable ring 508 to deflect. When deflecting, the movable ring 508 will rise and fall on the outside of the movable tube 506, and at the same time drive the movable tube 506 to move, so that the movable tube 506 will drive the blowing tube 507 to move, so that the blowing tube 507 can not only blow air to the bottom of the transformer body 1, but also blow air to both sides of the transformer body 1.

[0038] like Figure 6 and Figure 7As shown, the drip assembly 6 includes a drip frame 601 sleeved on the outside of the transformer body 1, fixed rods 602 are fixedly connected to both sides of the drip frame 601, and the bottom end of the fixed rod 602 is fixedly connected to the water guide plate 4, and a water supply channel connected to the drip frame 601 is opened inside the fixed rod 602 on the left side, and a hose 603 connected to the water supply channel is connected to the fixed rod 602, and a sleeve 604 connected to the bottom end of the hose 603 is fixedly connected, and the sleeve 604 is fixedly connected to the inner wall of the water tank 3, and a spring 605 is fixedly connected to the inner wall of the left side of the sleeve 604, and a hollow piston ring 606 is fixedly connected to the right end of the spring 605, and the hollow piston ring 60 6 is in close contact with the inner wall of the sleeve 604, and an extrusion block 607 is provided in the internal movable sleeve of the hollow piston ring 606. A push rod 608 is fixedly connected to one side of the extrusion block 607, and a moving frame 609 is fixedly connected to the end of the push rod 608 away from the extrusion block 607, and the moving frame 609 is threadedly sleeved on the outside of the screw rod 511. The dual-axis motor 512 drives the screw rod 511 to rotate, and the rotation of the screw 511 also drives the moving frame 609 to move. The moving frame 609 drives the extrusion block 607 to extrude the hollow piston ring 606, so that the extrusion block 607 and the hollow piston ring 606 compress the spring 605 to move, thereby sending water into the drip frame 601 through the hose 603.

[0039] like Figure 7 and Figure 8 As shown, the wetting component 7 includes a movable plate 701 movably sleeved on the outside of the fixed rod 602, a lifting frame 702 is fixedly connected between the two movable plates 701, and the lifting frame 702 is movably sleeved on the outside of the transformer body 1, a plurality of sponges 703 are fixedly connected inside the lifting frame 702, and the sponges 703 wet the heat sink, the internal thread sleeve of the movable plate 701 located on the right side is provided with a reciprocating screw 704, and the reciprocating screw 704 is rotatably connected to the water guide plate 4, the bottom end of the reciprocating screw 704 is fixedly connected to a driven bevel gear 705, and the active bevel gear 514 is meshed with the driven bevel gear 705 for transmission, the water in the drip frame 601 will fall onto the sponge 703 to wet the sponge 703, and the sponge 703 moves and wets the heat sink and the shell of the transformer body 1 after being soaked in water.

[0040] like Fig.10 As shown, the active bevel gear 514 includes a gear plate 51401 fixedly connected to the transmission shaft 513, and the outer array of the gear plate 51401 is hinged with a plurality of teeth 51402. The teeth 51402 on the active bevel gear 514 can only be engaged with the driven bevel gear 705 in one-way rotation, and can only be engaged normally when the extrusion block 607 and the hollow piston ring 606 push the water to be delivered. When the extrusion block 607 is away from the hollow piston ring 606, the teeth 51402 and the driven bevel gear 705 cannot be engaged for transmission.

[0041] like Figure 7 and Fig. 9 As shown, a fixing hole is provided at the bottom of the water tank 3, and the coil 503 is sealed and passes through the fixing hole, two plug holes are provided on the torsion plate 510, and the toggle rod 509 is movably sleeved in the plug holes, and installation holes 9 are provided on the two side walls of the water tank 3, and the transition tube 505 is fixedly sleeved in the installation holes 9.

[0042] like Fig. 9 As shown, a water inlet pipe 8 is fixedly mounted on one side of the water tank 3, and the other end of the water inlet pipe 8 is connected to a faucet. The faucet is turned on to replenish the water tank 3 with water through the water inlet pipe, and the water tank 3 is filled with water to increase the counterweight, which is beneficial to the stability of the installation of the transformer body 1.

[0043] like Figure 4 and Figure 7 As shown, the vertical and top sides of the movable frame 609 slide closely on the surface of the water tank 3, a guide hole is provided on the movable plate 701, and the movable plate 701 is movably mounted on the outside of the fixed rod 602 with the help of the guide hole, and the movable frame 609 slides closely on the inner wall of the water tank 3, so that the movable frame 609 can be guided to prevent the movable frame 609 from deflecting.

[0044] like Figure 7 As shown, a plurality of drip holes are arranged in an array at the bottom of the drip frame 601, through which water drips downward.

[0045] Working principle: ice cubes are added to the water tank 3 in hot weather, and the coil 503 is exchanged with ice water. The air pump 502 sends gas into the coil 503. After the coil 503 is immersed in ice water for heat exchange, cold air will enter the fixed pipe 504 and the movable pipe 506, and finally enter the blowing pipe 507. The blowing pipe 507 is used to blow cold air to cool the transformer body 1. The double-axis motor 512 is driven forward to drive the screw 511 to rotate. The rotation of the screw 511 will drive the torsion plate 510 to rotate horizontally. The torsion plate 510 rotates the water During the leveling process, the toggle rod 509 and the movable ring 508 will be deflected. When the movable ring 508 is deflected, it will rise and fall outside the movable tube 506, and at the same time, it will drive the movable tube 506 to move. In this way, the movable tube 506 will drive the blowing tube 507 to move, so that the two blowing tubes 507 move from the bottom of the transformer body 1 to both sides. In this way, the blowing tube 507 can not only blow air to the bottom of the transformer body 1, but also blow air to both sides of the transformer body 1. When the screw 511 rotates, it also drives the moving frame 609 to move. The moving frame 609 moves from the right side to the left side of the screw rod 511, and the moving frame 609 drives the extrusion block 607 to squeeze the hollow piston ring 606, so that the extrusion block 607 and the hollow piston ring 606 compress the spring 605 to move, thereby sending water into the drip frame 601 through the hose 603, and the water drips downward through the drip hole to wet the sponge 703. When the dual-axis motor 512 is driven in the forward direction, it also drives the transmission shaft 513 to rotate, and the transmission shaft 513 drives the driven bevel gear 514 and the driven bevel gear 705 to drive the transmission shaft 513 to rotate. The movable reciprocating screw rod 704 rotates, and the rotation of the reciprocating screw rod 704 will drive the movable plate 701 and the lifting frame 702 to move downward, and the lifting frame 702 will drive the sponge 703 to move downward, so that the sponge 703 will wet the heat sink and the shell of the transformer main body 1, and the evaporation of water will be used to improve the efficiency of heat dissipation. When driven in the forward direction, the teeth 51402 on the active bevel gear 514 can only be engaged with the driven bevel gear 705 in one-way rotation, that is, they can only be engaged normally when the extrusion block 607 and the hollow piston ring 606 push the water to deliver.

[0046] When the dual-axis motor 512 is driven in the reverse direction, the tooth 51402 and the driven bevel gear 705 cannot be meshed for transmission, which will drive the two blowing pipes 507 to close in the middle and blow air to the bottom of the transformer body 1 again, and the screw 511 drives the moving frame 609 to move right, and the moving frame 609 drives the extrusion block 607 to move right through the push rod 608. Since the hollow piston ring 606 is in close contact with the inner wall of the sleeve 604, the hollow piston ring 606 is relatively slow to reset by the elastic force of the spring 605, while the extrusion block 607 can quickly move away. The lifting frame 702 drives the sponge 703 to move to the middle of the heat sink and stay there. Only when the dual-axis motor 512 is driven forward again, the lifting frame 702 drives the sponge 703 to move to the bottom of the heat sink, which is also the bottom of the reciprocating screw rod 704. This reciprocating process can drive the sponge 703 to move up and down to continuously moisten the heat sink and the shell of the transformer main body 1, and then use wind to accelerate the evaporation of water, thereby greatly improving the heat dissipation efficiency of the transformer.
