[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1-Figure 6 As shown, an adjustable box-type transformer cabinet with multi-mode heat dissipation provided by an embodiment of the present invention includes a cabinet 1, a multi-functional hole 11 is provided on the side wall of the cabinet 1, a plurality of heat dissipation holes are provided on the bottom wall of the cabinet 1, and a drive box 12 is provided at the bottom of the cabinet 1; and further includes:

[0027] The sealing module 2 comprises a flexible sealing cover 21 installed inside the cabinet 1, the flexible sealing cover 21 is fitted with the inner wall of the cabinet 1, and the flexible sealing cover 21 is provided with a matching hole 211 matching the multifunctional hole 11, and the four corners inside the cabinet 1 are provided with an adjustment shaft 22, and the drive box 12 is also provided with a transmission unit 4 for driving each adjustment shaft 22 to rotate synchronously, and the upper and lower ends of each adjustment shaft 22 are provided with a transmission gear 24, and the upper and lower ends of the inner wall of the flexible sealing cover 21 are provided with a toothed belt 23 meshing with the transmission gear 24;

[0028] The heat dissipation module 3 includes a driving motor 31 installed in a driving box 12, the output end of the driving motor 31 is connected to a driving shaft 32, a fan 33 is installed on the driving shaft 32, and the driving box 12 is also provided with an adjustment unit 5 for adjusting the connection state between the transmission unit 4 and the driving shaft 32.

[0029] In the embodiment of the present invention, when in use, the device has two states, one of which is when the matching hole 211 is aligned with the corresponding multifunctional hole 11, at which time the inside of the cabinet 1 is in a state of communication with the outside world, and the electrical components can be disassembled or repaired, and can also be used for ventilation and heat dissipation when the external environment is suitable (no rain, etc.). The second is that the matching hole 211 and the multifunctional hole 11 are mutually misaligned, and at this time, the multifunctional holes 11 can be blocked by the flexible sealing cover 21, and at this time, the inside of the cabinet 1 is not in communication with the outside world and is in a sealed state, which can prevent dust and water vapor from the outside from entering the inside of the cabinet 1. When in use, it is only necessary to start the drive motor 31, and the drive motor 31 can drive the drive shaft 32 to rotate, and the drive shaft 32 can drive the fan 33 to rotate, so that the hot air inside the cabinet 1 is discharged from the bottom of the cabinet 1. When the matching relationship between the multifunctional hole position 11 and the matching hole position 211 is to be switched, it is only necessary to connect the transmission unit 4 to the drive shaft 32 through the adjustment unit 5. The drive shaft 32 can drive the adjustment shafts 22 to rotate synchronously through the transmission unit 4. The adjustment shafts 22 drive the transmission gear 24 to rotate. Through the cooperation between the transmission gear 24 and the toothed belt 23, the flexible sealing cover 21 can be driven to move along the inner wall of the cabinet 1, so that the matching hole position 211 is aligned or misaligned with the multifunctional hole position 11.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment of the present invention, a bottom plate 13 and a top plate 14 are further provided inside the cabinet 1. The bottom plate 13 is provided above the transmission gear 24 located at the bottom, and the top plate 14 is provided below the transmission gear 24 located at the top. The transmission gear 24 and the toothed belt 23 can be separated in independent chambers by the bottom plate 13 and the top plate 14, thereby ensuring that the area inside the cabinet 1 for installing electrical components remains regular, which is convenient for the installation and placement of equipment.

[0031] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the two adjusting shafts 22 on the same side are connected by a pulley belt mechanism 25, so that the two adjusting shafts 22 on the same side can keep rotating synchronously through the pulley belt mechanism 25.

[0032] like Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the transmission unit 4 includes two driving pulleys 41 and two transmission pulleys 42, the two driving pulleys 41 are symmetrically mounted on the driving shaft 32, and the driving pulleys 41 and the driving shaft 32 are rotationally connected, the two transmission pulleys 42 are respectively mounted on an adjusting shaft 22 on both sides, and each driving pulley 41 is connected to a driving pulley 42 through a transmission belt 43, and two engaging seats 44 are symmetrically arranged on the driving shaft 32, and the two engaging seats 44 are located between the two driving pulleys 41, and the opposite end surfaces of the two driving pulleys 41 are provided with engaging grooves 411 matching the engaging seats 44, the engaging seats 44 are connected to the driving shaft 32 through a sliding key, and the two engaging seats 44 are connected to each other through a reset spring 45, and when not subjected to external force, the reset spring 45 is in a contracted state;

[0033] The adjusting unit 5 adjusts the connection state between the engaging seats 44 and the engaging grooves 411 by pushing the two engaging seats 44 to slide along the axial direction of the driving shaft 32 .

[0034] In the embodiment of the present invention, in the initial state, the return spring 45 is in a contracted state, at which time the two engaging seats 44 are not in contact with the engaging groove 411 in the driving pulley 41, so the driving shaft 32 will not drive the driving pulley 41 to rotate synchronously. When the adjusting shaft 22 is to be driven to rotate, it is only necessary to drive the two engaging seats 44 to move in opposite directions along the axial direction of the driving shaft 32 through the adjusting unit 5, so that the engaging seats 44 are engaged in the engaging groove 411, thereby driving the driving pulley 41 to rotate through the engaging seats 44, and the driving pulley 41 can drive the driving pulley 42 to rotate through the transmission belt 43, thereby driving the corresponding adjusting shaft 22 to rotate.

[0035] like Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the adjusting unit 5 includes two mounting plates 51 symmetrically arranged on both sides of the driving shaft 32, and a telescopic member 52 is installed on the opposite side of the two mounting plates 51, and an arc-shaped push block 53 is provided at the telescopic end of the telescopic member 52, and the upper and lower ends of the arc-shaped push block 53 on the side close to the driving shaft 32 are provided with a second inclined surface 531, and the end of the locking seat 44 is provided with a first inclined surface 441 matching the second inclined surface 531.

[0036] In the embodiment of the present invention, the telescopic member 52 is an electric telescopic rod. In the initial state, the telescopic member 52 is in a retracted state, and the arc-shaped push block 53 is not in contact with the engaging seat 44. When the driving pulley 41 is to be driven to rotate by the driving shaft 32, it is only necessary to control the telescopic member 52 to extend, and the telescopic member 52 can drive the arc-shaped push block 53 to move toward the side close to the driving shaft 32, so that the second inclined surface 531 abuts against the first inclined surface 441. As the telescopic member 52 continues to extend, the two engaging seats 44 can be pushed to move in opposite directions at the same time, thereby pushing the engaging seats 44 to engage with the engaging groove 411. When the telescopic member 52 returns to the initial state, the two engaging seats 44 will synchronously return to the initial position under the elastic force of the reset spring 45.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment of the present invention, the adjusting shaft 22 is a hollow structure, and the area where the adjusting shaft 22 is located between the bottom plate 13 and the top plate 14 is provided with a plurality of air outlet holes 221 equidistantly distributed, and the top of the cabinet 1 is also provided with an air supply pipe 26 for connecting an external air pump, and the top of each adjusting shaft 22 is connected to the air supply pipe 26.

[0038] In the embodiment of the present invention, the top of each adjusting shaft 22 can be connected to the gas pipe 26 through a rotating joint, and it is only necessary to ensure that the gas pipe 26 smoothly delivers gas to the adjusting shaft 22 and does not affect the rotation of the adjusting shaft 22. An external air pump can deliver gas to each adjusting shaft 22 through the gas pipe 26, and then blow air into the cabinet 1 through the air outlet 221 on the adjusting shaft 22, so as to cool the inside of the cabinet 1 and effectively prevent the temperature inside the cabinet 1 from being too high.

[0039] Working principle: When in use, the device has two states. One is when the matching hole 211 is aligned with the corresponding multifunctional hole 11. At this time, the inside of the cabinet 1 is in a state of communication with the outside world, and the electrical components can be disassembled or repaired. It can also be used for ventilation and heat dissipation when the external environment is suitable (no rain, etc.). The second is that the matching hole 211 and the multifunctional hole 11 are misaligned with each other. At this time, the multifunctional holes 11 can be blocked by the flexible sealing cover 21. At this time, the inside of the cabinet 1 is not connected to the outside world and is in a sealed state, which can prevent dust and water vapor from the outside from entering the inside of the cabinet 1. When in use, it is only necessary to start the drive motor 31, and the drive motor 31 can drive the drive shaft 32 to rotate, and the drive shaft 32 can drive the fan 33 to rotate, so that the hot air inside the cabinet 1 is discharged from the bottom of the cabinet 1. When the matching relationship between the multifunctional hole position 11 and the matching hole position 211 is to be switched, it is only necessary to control the telescopic member 52 to extend, and the telescopic member 52 can drive the arc-shaped push block 53 to move toward the side close to the drive shaft 32, so that the second inclined surface 531 abuts against the first inclined surface 441. As the telescopic member 52 continues to extend, the two engaging seats 44 can be pushed to move in opposite directions at the same time, so as to push the engaging seats 44 to engage with the engaging grooves 411. The drive shaft 32 can drive the driving pulley 41 to rotate through the engaging seat 44, and the driving pulley 41 can drive the driving pulley 42 to rotate through the transmission belt 43, thereby driving the corresponding adjustment shaft 22 to rotate. The two adjustment shafts 22 on the same side are kept in synchronous rotation through the pulley belt mechanism 25, so that each adjustment shaft 22 rotates synchronously. The adjusting shaft 22 drives the transmission gear 24 to rotate, and through the cooperation of the transmission gear 24 and the toothed belt 23, the flexible sealing cover 21 can be driven to move along the inner wall of the cabinet 1, so that the matching hole 211 is aligned or misaligned with the multifunctional hole 11. In addition, the external air pump can deliver gas to each adjusting shaft 22 through the air delivery pipe 26, and then blow air into the cabinet 1 through the air outlet 221 on the adjusting shaft 22, so as to cool the inside of the cabinet 1 and effectively prevent the internal temperature of the cabinet 1 from being too high.
