[0002] A transformer is a static electrical device used to transform AC voltage and current and transmit AC electrical energy. It realizes the transmission of electrical energy based on the principle of electromagnetic induction. Transformers can be classified into power transformers, test transformers, instrument transformers, and transformers for special purposes according to their uses: power transformers are necessary equipment for power transmission and distribution and power user distribution; test transformers are equipment for performing withstand voltage (boost voltage) tests on electrical equipment.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0025] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a multi - directional cooling structure, the multi - directional cooling structure includes two legs 1 and a disc 2 fixedly installed between the two legs 1, and a pump gas mechanism for absorbing the heat generated during the operation of the transformer is installed on the upper part of the disc 2, and the pump gas mechanism is connected to a rotating pipe 6 rotatably installed on the disc 2;

[0026] The rotating tube 6 extends to the bottom of the disc 2, and a cross plate 7 parallel to the disc 2 is fixed at the end. A suction head 9 is movably arranged below the cross plate 7 through a reciprocating driving mechanism. The suction head 9 is connected to the air pumping mechanism through a connecting pipe group. A circumferential rotating mechanism is also installed on the cross plate 7. The circumferential rotating mechanism is triggered during the rotation of the cross plate 6, and the circumferential rotating mechanism also cooperates with the reciprocating driving mechanism.

[0027] In the specific implementation of the present invention, the air pumping mechanism works, and absorbs the heat generated during the operation of the transformer through the connecting pipe group and the suction head 9. At the same time, the air pumping mechanism drives the rotating tube 6 and the cross plate 7 to rotate, and the suction head 9 makes a circular motion around the transformer. During this process, the circumferential rotating mechanism is triggered to move and cooperate with the reciprocating driving mechanism, so that the reciprocating driving mechanism drives the suction head 9 to swing up and down during the circular motion. In this way, the multi-directional heat absorption function is realized, greatly improving the heat dissipation efficiency of the transformer and providing guarantee for the normal operation of the transformer.

[0028] The air pumping mechanism includes an air pump 3 installed on the upper part of the disc 2. A driving motor 4 is installed on the side of the air pump 3. The output end of the driving motor 4 is connected to the driving shaft of the air pump 3. The driving shaft of the air pump 3 is also connected to the rotating tube 6 through a transmission belt 21 and a first bevel gear set 17. Its air inlet is connected to the suction head 9 through the connecting pipe group and the rotating tube 6.

[0029] The connecting pipe group includes a collar 5 installed on the air inlet of the air pump 3, a conduit 20 installed on the cross plate 7 and communicated with the rotating tube 6, and a hose 8 connecting the conduit 20 and the suction head 9. The collar 5 is sleeved on the outer periphery of the rotating tube 6 and is in sealed rotational connection with it;

[0030] Wherein, a circle of through holes is opened on the inner wall of the collar 5, and a circle of through holes is also opened on the part of the rotating tube 6 covered by the collar 5.

[0031] When the driving motor 4 works, it drives the air pump 3 to work. Thus, the air pump 3 absorbs the heat generated during the operation of the transformer through the collar 5, the rotating tube 6, the conduit 20, the hose 8 and the suction head 9. At the same time, the driving shaft of the air pump 3 drives the rotating tube 6 to rotate through the transmission belt 21 and the first bevel gear set 17, so that the cross plate 7 rotates, and the suction head 9 absorbs the heat in a circular manner.

[0032] The circumferential rotating mechanism includes an engaging component installed on the cross plate 7 and a rotating component installed at the bottom of the cross plate 7 and connected to the engaging component. The engaging component is triggered to move during the rotation of the cross plate 7 and drives the rotating component to cooperate with the reciprocating driving mechanism.

[0033] The meshing assembly includes a gear 18 rotatably mounted on the upper part of the cross plate 7 and a fixed ring 19 provided at the bottom of the disc 2. A plurality of teeth meshing with the gear 18 are equidistantly arranged along the circumference on the inner wall of the fixed ring 19, and the central axes of the fixed ring 19, the rotating tube 6, and the disc coincide with each other.

[0034] The rotating assembly includes a turntable 14 rotatably mounted below the cross plate 7. The central axes of the turntable 14 and the disc 2 are perpendicular to each other, and the rotating shafts of the turntable 14 and the gear 18 are connected by a second bevel gear set 22. A protruding column 16 is also provided at the eccentric position of the turntable 14, and the protruding column 16 cooperates with the reciprocating driving mechanism during the rotation of the turntable 14.

[0035] Among them, it should be further noted that the first bevel gear set 17 includes a first bevel gear fixed on the driving shaft of the air pump 3 and a second bevel gear fixed on the rotating tube 6 and meshing with the first bevel gear;

[0036] Similarly, the second bevel gear set 22 includes a third bevel gear and a fourth bevel gear respectively fixed at the ends of the rotating shafts of the gear 18 and the turntable 14, and the third bevel gear meshes with the fourth bevel gear.

[0037] The reciprocating driving mechanism includes a guide plate 10 fixed to the lower part of the cross plate 7, a sliding plate 11 slidably fitted on the side of the guide plate 10, and a reciprocating plate 12 rotatably mounted at the bottom of the guide plate 10. The suction head 9 is provided on the reciprocating plate 12;

[0038] The reciprocating plate 12 is connected to the sliding plate 11 through a push rod 13, and both ends of the push rod 13 are rotatably connected to the sliding plate 11 and the reciprocating plate 13 respectively. Two long rods 15 are also fixed on the side of the sliding plate 11, and a gap is reserved between the two long rods 15, and the protruding column 16 extends into the gap.

[0039] During the process of the rotating tube 6 driving the cross plate 7 to rotate, the gear 18 moves and meshes with the teeth on the inner wall of the fixed ring 19 to rotate. Its rotating shaft drives the turntable 14 to rotate through the second bevel gear set 22. The protruding column 16 is slidably fitted with the sliding plate 11 through the two long rods 15. Thus, the sliding plate 11 reciprocates up and down on the side of the guide plate 10 and drives the reciprocating plate 12 and the suction head 9 to swing reciprocally through the push rod 13. In this way, the circular motion and the reciprocating swing of the suction head 9 occur simultaneously, causing the heat absorption direction of the suction head 9 to change continuously, improving the heat dissipation range and effect.
