It is arranged on the water pump 43, and a water outlet pipe 45 is fixedly arranged at one end of the heat dissipation pipe 41 away from the water inlet pipe 44, and the end of the water outlet pipe 45 away from the heat dissipation pipe 41 is fixedly arranged in the water tank 42, and symmetrically distributed positioning holes 16 are opened through the substation box 1, and fan blades 17 are arranged in the positioning holes 16. The upper surface of the substation box 1 is fixedly provided with symmetrically distributed first positioning blocks 18, and a positioning plate 19 is fixedly arranged between the two first positioning blocks 18. A symmetrically distributed rotating rod 2 is rotatably arranged on the positioning plate 19, and the end of the rotating rod 2 away from the positioning plate 19 is fixedly arranged on the fan blade 17.

[0019] A belt 21 is rotatably provided at one end of the two rotating rods 2 away from the fan blades 17 ; the belt 21 can make the two rotating rods 2 rotate together, thereby driving the two fan blades 17 to rotate together.

[0020] The upper surface of the substation box 1 is fixed with symmetrically distributed fixing blocks 22, and symmetrically distributed air outlets 23 are formed between the two fixing blocks 22. The two fixing blocks 22 are commonly fixed with a plurality of equally spaced inclined plates 24 near the outlets, and a fixing plate 25 is solidly fixed between the two fixing blocks 22; the air outlet 23 can discharge the heat in the substation box 1 through the air outlet 23 to reduce the temperature in the substation box 1, and the inclined plate 24 can prevent rainwater and other debris from entering the substation box 1 through the air outlet 23 to cause damage to the components.

[0021] A motor 3 is fixedly provided on a fixed block 22 on one side, a first bevel gear 31 is fixedly provided on the end of the output shaft of the motor 3, and a second bevel gear 32 is fixedly provided on one end of the rotating rod 2 close to the belt 21 on one side, and the first bevel gear 31 and the second bevel gear 32 are meshed with each other; the first bevel gear 31 can be driven by the motor 3, and since the first bevel gear 31 and the second bevel gear 32 are meshed with each other, when the first bevel gear 31 rotates, it will drive the second bevel gear 32 to rotate, and then drive the rotating rod 2 to rotate through the second bevel gear 32.

[0022] A plurality of baffles 33 are fixedly provided near the air inlet 12 of the box door 11 and are distributed at equal intervals. The baffles 33 can prevent debris from entering the transformer substation box body 1 through the air inlet 12 to avoid damage to the components.

[0023] A second positioning block 34 is fixedly provided on one side of the box door 11 close to the transformer body 13, and a positioning groove 35 is opened on the second positioning block 34. A filter 36 is movably provided in the positioning groove 35, and a handle 37 is fixedly provided on the filter 36; the air entering through the air inlet 12 can be filtered through the filter 36, and dust is filtered through the filter 36 to prevent dust accumulation in the substation box 1 from affecting the normal operation of electronic components.

[0024] Working principle: When in use, since the transformer body 13 is fixedly arranged on the upper surface of the soaking plate 4, the heat generated by the transformer body 13 when working will be conducted to the soaking plate 4. Since the lower surface of the soaking plate 4 is fixedly provided with a heat dissipation pipe 41, and there is coolant in the heat dissipation pipe 41, the heat on the soaking plate 4 will be absorbed by the coolant, and the heated coolant will enter the water tank 42 through the water outlet pipe 45. At the same time, the new coolant will flow back into the heat dissipation pipe 41 through the water inlet pipe 44 under the action of the water pump 43 to absorb the heat on the soaking plate 4. Through the above operation, the transformer body 13 can be continuously cooled down;

[0025] When the motor 3 is working, the first bevel gear 31 fixedly connected to the end of the output shaft of the motor 3 will rotate under the drive of the motor 3. Because the first bevel gear 31 and the second bevel gear 32 are meshed with each other, the first bevel gear 31 will drive the second bevel gear 32 to rotate when it rotates. Because the rotating rod 2 is fixedly set on the second bevel gear 32, when the second bevel gear 32 is turned, it will drive the rotating rod 2 to rotate. Because the end of the rotating rod 2 away from the positioning plate 19 is fixedly provided with a fan blade 17, and a belt 21 is provided between the two rotating rods 2 for common rotation, when one rotating rod 2 rotates, the other rotating rod 2 will rotate synchronously, and drive the fan blade 17 to rotate through the rotating rod 2. As the fan blade 17 rotates, the hot air in the substation box 1 is discharged. At this time, the substation box 1 forms a negative pressure, allowing external air to enter through the air inlet 12. Through the above operation, air circulation can be formed in the substation box 1 to prevent the temperature in the substation box 1 from being too high and causing damage to the components.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
