Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to an incubator-type transformer for high-precision power consumption requirements of industrial equipment. Background Art

[0002] An incubator-type transformer is designed to meet the high-precision power consumption requirements of industrial equipment. In traditional industrial production, ordinary transformers are vulnerable to environmental temperature, resulting in unstable output voltage, affecting the normal operation of equipment and product quality. In addition, temperature changes will accelerate the aging of internal components of the transformer, reducing the service life and increasing the maintenance cost. Therefore, an incubator-type transformer that can stably control the internal temperature and ensure the accuracy of output voltage has emerged, which can meet the high requirements of industrial equipment for power consumption.

[0003] In the patent with the publication number CN220873397U, an automatic temperature control box-type transformer is disclosed, which includes a box body, a transformer body, a controller, an electric fan, a support block and a heat sink. The transformer body is installed in the middle of the box body, the controller is installed on the front right side of the top of the box body, electric fans are embedded on both left and right sides of the box body, support blocks are symmetrically fixed on the front and back of the upper left and right sides of the box body, and a plurality of heat sinks are arranged on the tops of the support blocks on both left and right sides. The internal temperature is sensed by a detector and the information is transmitted to the controller. By controlling and adjusting the power of the first water pump, the speed of oil circulation can be controlled, so as to take away the internal heat of the transformer body. By adjusting the power of the electric fan, the air flow rate can be controlled, so as to control the cooling effect of the hot oil, realizing automatic constant temperature control of the temperature inside the transformer, and enabling the transformer to work at a suitable temperature.

[0004] The existing technology has the following defects:

[0005] High energy consumption of the heat dissipation mechanism: The existing heat dissipation methods of transformers usually adopt air cooling and oil cooling. Air cooling relies on the continuous operation of the fan, which needs to operate at high power during high-temperature periods, and will consume a large amount of electric energy after long-term use. Oil cooling requires the operation of the oil pump and the cooling device, and the entire system has high energy consumption. Moreover, the oil cooling equipment itself has a high power and high maintenance cost. Therefore, a structure for cooling and heat preservation by wetting sand can be set. The heat dissipation of wet sand mainly relies on the natural evaporation of water to take away heat. The water evaporation process does not require additional consumption of a large amount of electric energy, and only consumes a small amount of electric energy in auxiliary links such as automatic water replenishment. The overall energy consumption is significantly reduced, and the procurement cost of sand is extremely low, which can greatly reduce the initial construction cost of the transformer, achieving the effects of reducing energy consumption and cost.

[0006] The ventilation window cannot be adjusted: The existing ventilation windows are generally fixedly opened and cannot be adjusted. In a high-temperature environment, the opening of the ventilation window cannot be increased, resulting in poor heat dissipation, continuous increase in the temperature inside the box, affecting the performance and lifespan of the transformer, and even potentially causing faults. In a low-temperature environment, the opening of the ventilation window cannot be reduced, allowing a large amount of cold air to enter, making the temperature inside the box too low, which is also not conducive to the stable operation of the transformer. Therefore, a structure that can adjust the ventilation window is needed to make the temperature distribution inside the box more uniform, improve the power usage stability, and meet the high-precision power consumption requirements of industrial equipment. Summary of the Invention

[0007] In view of the problems in the prior art such as high energy consumption of the heat dissipation mechanism and inability to adjust the ventilation window, a constant-temperature box-type transformer for high-precision power consumption requirements of industrial equipment is proposed.

[0008] This application provides a constant-temperature box-type transformer for high-precision power consumption requirements of industrial equipment, and its purpose is: by setting the platform component and the adjustment mechanism, wetting the sand for cooling and heat preservation. The heat dissipation of wet sand mainly relies on the natural evaporation of water to take away heat. The water evaporation process does not require a large amount of additional electrical energy consumption, and only consumes a small amount of electricity in auxiliary links such as automatic water replenishment. The overall energy consumption is significantly reduced, and the procurement cost of sand is extremely low, which can greatly reduce the initial construction cost of the transformer, achieving the effects of reducing energy consumption and cost. At the same time, the ventilation window can be adjusted to make the temperature distribution inside the box more uniform, improve the power usage stability, and meet the high-precision power consumption requirements of industrial equipment.

[0009] The technical solution of the present invention is: a constant-temperature box-type transformer for high-precision power consumption requirements of industrial equipment, including a housing, a platform component fixedly installed at the bottom of the housing, a top cover fixedly installed at the top of the housing, an adjustment mechanism fixedly installed inside the housing frame, and a voltage transformation device located in the middle of the housing. The adjustment mechanism maintains the constant temperature of the voltage transformation device through adjustment. The top cover is used to collect rainwater, the platform component is used to store water, the adjustment mechanism includes a protection net, a sand storage component and a sealing component arranged inside the housing frame, a driving component arranged above the sand storage component and the sealing component, and a stirring component arranged inside the sand storage component;

[0010] The sand storage component includes a support block slidably connected to the inner wall of the housing. Three support rods are fixedly connected to the bottom of the support block. An air-permeable membrane is fixedly connected between any two of the support rods. The three support rods and the three air-permeable membranes together enclose a sand storage cylinder. The bottoms of the three support rods are fixedly connected with a wetting frame. A water-permeable plate is fixedly connected to the inner wall of the wetting frame. Sand is filled between the water-permeable plate and the sand storage cylinder.

[0011] With the above - mentioned solution, through the sand - storage component provided, when the temperature of the voltage - transformation equipment is relatively high and auxiliary cooling is required, the platform component inputs water into the wetting frame through the through - holes. After the water in the wetting frame is full, the water will flow through the water - permeable plate into the sand - storage cylinder, gradually wetting the sand in the sand - storage cylinder, and the moisture will spread upward. The heat dissipated by the voltage - transformation equipment enters the wetted sand - storage cylinder through the breathable membrane. Since sand has good thermal conductivity, it can adsorb heat and take away a large amount of heat with the evaporation of moisture. When the temperature of the voltage - transformation equipment is relatively low and heat preservation is required, the driving component drives the support block and the wetting frame to rotate by 54°. This rotation makes the hypotenuses of multiple sand - storage cylinders connected, forming a plane parallel to the protection net, thus enhancing the resistance to external impacts. Moreover, after the moisture in the wetted sand evaporates, the remaining sand can also slow down the heat dissipation to a certain extent, helping to maintain the temperature inside the box in a low - temperature environment.

[0012] Furthermore, the sand - storage component further includes a first driving shaft rotatably connected to the inner wall of the outer shell. Connecting rods are fixedly connected between the first driving shaft and both the support block and the wetting frame, and a first driving gear is fixedly connected to the outer wall of the first driving shaft.

[0013] With the above - mentioned solution, through the first driving gear and the driving shaft provided, the first driving gear can drive the support block and the wetting frame to rotate through the first driving shaft and the connecting rod, playing a role in adjusting the shape.

[0014] Furthermore, the stirring component includes a connecting rope slidably connected inside the support block and the wetting frame. A plurality of stirring blocks are fixedly connected to the outer wall of the connecting rope, and all the plurality of stirring blocks are arranged inside the sand - storage cylinder.

[0015] Furthermore, one end of the connecting rope close to the support block is fixedly connected to the inner wall of the outer shell, and a gravity block is fixedly connected to the end of the connecting rope close to the wetting frame. The gravity block is slidably connected to the inner wall of the outer shell, and a telescopic spring is fixedly connected between the top of the gravity block and the inner wall of the outer shell.

[0016] With the above - mentioned solution, through the stirring component provided, when the sand - storage cylinder rotates, the stirring blocks inside it will move upward under the traction of the connecting rope, driving part of the sand to move upward. When the sand - storage cylinder returns to its original position, the stirring blocks will move downward and reset under the combined action of the telescopic spring and the gravity block. In this way, the sand in the sand - storage cylinder is stirred to prevent the sand from caking and ensure the uniformity of heat dissipation and heat absorption.

[0017] Furthermore, the sealing component includes a second driving shaft rotatably connected to the inner wall of the outer shell. A sealing plate is fixedly connected to the outer wall of the second driving shaft. A plurality of ventilation grooves are opened on the inner wall of the outer shell, and the sealing plate rotates inside the corresponding ventilation grooves. A second driving gear is also fixedly connected to the outer wall of the second driving shaft.

[0018] With the above - mentioned solution, through the set sealing component, when the temperature of the voltage - transforming equipment is relatively high and auxiliary cooling is required, the sealing plate in the ventilation slot is in an open state. When the temperature of the voltage - transforming equipment is relatively low and heat preservation is required, the second driving gear drives the sealing plate to rotate 90° in the ventilation slot through the second driving shaft, so that the sealing plate completely seals the ventilation slot, effectively reducing heat dissipation and playing a role in heat - preservation and sealing.

[0019] Furthermore, the driving component includes a rotating cylinder fixedly installed on the inner wall of the outer shell and a plurality of rack seats. A double - sided rack is slidably connected between two rack seats on the same side, and both sides of the double - sided rack are meshed with a plurality of first driving gears and a plurality of second driving gears respectively.

[0020] Furthermore, threaded rods are threadedly connected to the inner walls of both double - sided racks, and a synchronous transmission belt is drivingly connected between the outer walls of the two threaded rods. One of the threaded rods is sleeved on the output shaft of the rotating cylinder.

[0021] With the above - mentioned solution, through the set driving component, when the sand - storage cylinder needs to adjust its position, the rotating cylinder is operated. The output shaft of the rotating cylinder drives the two threaded rods to rotate simultaneously inside the two double - sided racks through the synchronous transmission belt. Subsequently, the two double - sided racks will slide in the corresponding rack seats, thereby driving a plurality of first driving gears and second driving gears to rotate, playing a role in providing power.

[0022] Furthermore, the platform component includes a water - storage platform fixedly installed at the bottom of the outer shell. An external connecting pipe and a vertical groove are communicated inside the water - storage platform, and the vertical groove penetrates through the inside of the outer shell and is communicated with the top cover.

[0023] Furthermore, a water - pump is fixedly connected to the inner wall of the water - storage platform. The output end of the water - pump is fixedly connected to a main water - conveying pipe. The main water - conveying pipe is branched into a plurality of connecting branch pipes. One end of each of the plurality of connecting branch pipes away from the main water - conveying pipe is communicated with a through - hole, and the plurality of through - holes are respectively arranged inside a plurality of wetting frames.

[0024] With the above - mentioned solution, through the set platform component and through - holes, when the temperature of the voltage - transforming equipment is relatively high and auxiliary cooling is required, the water - pump is operated. The water - pump will input the water inside the water - storage platform into the wetting frames through the main water - conveying pipe, connecting branch pipes, and through - holes. And when it rains, the rainwater collected by the top cover will be discharged into the water - storage platform through the vertical groove, which helps to save water resources. In addition, the external connecting pipe connected to the water - storage platform can directly access water from the outside to timely supplement the water volume in the water - storage platform and ensure the normal operation of the entire system.

[0025] The beneficial effects of the present invention:

[0026] With the provided platform component and sand storage component, when the temperature of the voltage transformation device is relatively high and auxiliary cooling is required, the water pump is operated. The water pump will pump the water inside the water storage platform through the main water pipeline and connecting branch pipes, and input it into the wetting frame through the through holes. After the wetting frame is filled with water, the water will flow through the water permeable plate into the sand storage cylinder, gradually wetting the sand in the sand storage cylinder, and the moisture will spread upward. At this time, the sealing plate in the ventilation slot is in the open state, and the heat dissipated by the voltage transformation device will pass through the ventilation slot and enter the wetted sand storage cylinder through the breathable film. Since the sand has good thermal conductivity, it can adsorb heat and take away a large amount of heat with the evaporation of moisture. At the same time, the water pump continuously supplies water, ensuring the continuity of the cooling process and effectively playing an auxiliary cooling role.

[0027] With the provided driving component and sealing component, when the temperature of the voltage transformation device is relatively low and heat preservation is required, the driving component is operated to drive multiple first driving gears and second driving gears to rotate. Among them, the first driving gear drives the support block and the wetting frame to rotate 54° through the first driving shaft and the connecting rod. This rotation causes the hypotenuses of multiple sand storage cylinders to be connected, forming a plane parallel to the protective net, thereby enhancing the resistance to external impacts. And after the water in the wetted sand evaporates completely, the remaining sand can also slow down the heat dissipation to a certain extent, helping to maintain the temperature inside the box in a low-temperature environment. At the same time, the second driving gear drives the sealing plate to rotate 90° in the ventilation slot through the second driving shaft, making the sealing plate completely seal the ventilation slot, effectively reducing heat dissipation and playing a role in closed heat preservation.

[0028] With the provided stirring component, when the sand storage cylinder rotates, the stirring block inside it will move upward under the traction of the connecting rope, driving part of the sand to move upward. When the sand storage cylinder returns to its original position, the stirring block will move downward and reset under the combined action of the telescopic spring and the gravity block. In this way, the sand in the sand storage cylinder is stirred to prevent the sand from caking and ensuring the uniformity of heat dissipation and heat absorption. Brief Description of the Drawings

[0042] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0043] Refer to Figure 1 - Figure 11, a constant-temperature box-type transformer for the high-precision power consumption requirements of industrial equipment is provided, including a housing 1, a base component 2 fixedly installed at the bottom of the housing 1, a top cover 3 fixedly installed at the top of the housing 1, an adjustment mechanism 5 fixedly installed inside the frame of the housing 1, and a voltage transformation device 4 located in the middle of the housing 1. The adjustment mechanism 5 maintains the constant temperature of the voltage transformation device 4 through adjustment. The top cover 3 is used to collect rainwater, the base component 2 is used to store water, the adjustment mechanism 5 includes a protective net 51 arranged inside the frame of the housing 1, a sand storage component 52 and a sealing component 54, a driving component 53 arranged above the sand storage component 52 and the sealing component 54, and a stirring component 55 arranged inside the sand storage component 52.

[0044] Refer to Figure 3 - Figure 5 , the sand storage component 52 includes a support block 521 slidably connected to the inner wall of the housing 1. Three support rods 528 are fixedly connected to the bottom of the support block 521. An air-permeable membrane 529 is fixedly connected between any two support rods 528. The three support rods 528 and the three air-permeable membranes 529 together enclose a sand storage cylinder 527. The bottoms of the three support rods 528 are fixedly connected to a wetting frame 525. A water-permeable plate 526 is fixedly connected to the inner wall of the wetting frame 525. Sand is filled between the water-permeable plate 526 and the sand storage cylinder 527.

[0045] Specifically, the sand storage cylinder 527 is jointly enclosed by the support block 521 at the top, the wetting frame 525 at the bottom, the three support rods 528 at the three top corners, and the three-sided air-permeable membrane 529. Sand is filled above the water-permeable plate 526 and inside the sand storage cylinder 527, and the filling amount is 80%. The holes of the air-permeable membrane 529 are smaller than water molecules and can only pass air. The holes of the water-permeable plate 526 are smaller than sand and can pass water molecules.

[0046] Through the arranged sand storage component 52, when the temperature of the voltage transformation device 4 is relatively high and auxiliary cooling is required, the base component 2 inputs water into the wetting frame 525 through the through hole 56. After the water in the wetting frame 525 is full, the water will pass through the water-permeable plate 526 and flow into the sand storage cylinder 527, making the sand in the sand storage cylinder 527 gradually get wet, and the moisture will spread upward. The heat dissipated by the voltage transformation device 4 enters the wet sand storage cylinder 527 through the air-permeable membrane 529. Since sand has good thermal conductivity, it can adsorb heat and take away a large amount of heat with the evaporation of moisture. When the temperature of the voltage transformation device 4 is relatively low and heat preservation is required, the driving component 53 drives the support block 521 and the wetting frame 525 to rotate 54°. This rotation makes the hypotenuses of multiple sand storage cylinders 527 connected together to form a plane parallel to the protective net 51, thus enhancing the resistance to external impacts. And after the moisture in the wet sand evaporates, the remaining sand can also slow down the heat dissipation to a certain extent, which helps to maintain the temperature inside the box in a low-temperature environment.

[0047] Refer toFigure 5 The sand storage assembly 52 further includes a first drive shaft 524 rotatably connected to the inner wall of the housing 1. Connecting rods 523 are fixedly connected between the first drive shaft 524 and both the support block 521 and the wetting frame 525. A first drive gear 522 is fixedly connected to the outer wall of the first drive shaft 524.

[0048] Through the arranged first drive gear 522 and first drive shaft 524, the first drive gear 522 can drive the support block 521 and the wetting frame 525 to rotate through the first drive shaft 524 and the connecting rod 523, playing a role in adjusting the shape.

[0049] Refer to Figure 5 - Figure 6 The stirring assembly 55 includes a connecting rope 551 slidably connected inside the support block 521 and the wetting frame 525. A plurality of stirring blocks 552 are fixedly connected to the outer wall of the connecting rope 551. The plurality of stirring blocks 552 are all arranged inside the sand storage cylinder 527. One end of the connecting rope 551 close to the support block 521 is fixedly connected to the inner wall of the housing 1. One end of the connecting rope 551 close to the wetting frame 525 is fixedly connected to a gravity block 554. The gravity block 554 is slidably connected to the inner wall of the housing 1. A telescopic spring 553 is fixedly connected between the top of the gravity block 554 and the inner wall of the housing 1.

[0050] Specifically, one end of the connecting rope 551 above is fixed to the inner wall of the housing 1, and the lower end is connected to the gravity block 554 which slides inside the housing 1. When the sand storage cylinder 527 rotates, the upper part of the connecting rope 551 is pulled, causing the stirring block 552 to move upward. When the sand storage cylinder 527 resets, the upper part of the connecting rope 551 is relaxed, and the lower part of the connecting rope 551 is pulled under the gravity of the gravity block 554 and the rebounding force of the telescopic spring 553, causing the stirring block 552 to move downward.

[0051] Through the arranged stirring assembly 55, when the sand storage cylinder 527 rotates, the stirring block 552 inside it will move upward under the traction of the connecting rope 551, driving part of the sand to move upward. When the sand storage cylinder 527 resets, the stirring block 552 will move downward and reset under the combined action of the telescopic spring 553 and the gravity block 554. In this way, the sand in the sand storage cylinder 527 is stirred to prevent the sand from caking and ensure the uniformity of heat dissipation and heat absorption.

[0052] Refer to Figure 7 - Figure 8 The sealing assembly 54 includes a second drive shaft 541 rotatably connected to the inner wall of the housing 1. A sealing plate 543 is fixedly connected to the outer wall of the second drive shaft 541. A plurality of ventilation grooves 544 are formed in the inner wall of the housing 1. The sealing plate 543 rotates inside the corresponding ventilation grooves 544. A second drive gear 542 is also fixedly connected to the outer wall of the second drive shaft 541.

[0053] Through the provided sealing component 54, when the temperature of the transformer equipment 4 is relatively high and auxiliary cooling is required, the sealing plate 543 in the ventilation slot 544 is in an open state. While when the temperature of the transformer equipment 4 is relatively low and heat preservation is required, the second driving gear 542 drives the sealing plate 543 to rotate 90° in the ventilation slot 544 through the second driving shaft 541, so that the sealing plate 543 completely seals the ventilation slot 544, effectively reducing heat dissipation and playing a role in heat preservation and enclosure.

[0054] Refer to Figure 7 - Figure 8 As shown in FIG. Figure 8 , the driving component 53 includes a rotating cylinder 531 fixedly installed on the inner wall of the housing 1 and a plurality of rack seats 535. A double-sided rack 534 is slidably connected between two rack seats 535 on the same side. The two sides of the double-sided rack 534 are respectively meshed with a plurality of first driving gears 522 and a plurality of second driving gears 542. Threaded rods 533 are threadedly connected to the inner walls of the two double-sided racks 534. A synchronous transmission belt 532 is drivingly connected between the outer walls of the two threaded rods 533. One of the threaded rods 533 is sleeved on the output shaft of the rotating cylinder 531.

[0055] Through the provided driving component 53, when the sand storage cylinder 527 needs to adjust its position, the rotating cylinder 531 is operated. The output shaft of the rotating cylinder 531 drives the two threaded rods 533 to rotate simultaneously inside the two double-sided racks 534 through the synchronous transmission belt 532. Subsequently, the two double-sided racks 534 will slide in the corresponding rack seats 535, thereby driving a plurality of first driving gears 522 and second driving gears 542 to rotate, playing a role in providing power.

[0056] Refer to Figure 9 - Figure 11 As shown in FIG. Figure 11 , the platform component 2 includes a water storage platform 21 fixedly installed at the bottom of the housing 1. An external connecting pipe 23 and a vertical groove 24 are communicated inside the water storage platform 21. The vertical groove 24 penetrates through the inside of the housing 1 and communicates with the top cover 3. A water pump 22 is fixedly connected to the inner wall of the water storage platform 21. The output end of the water pump 22 is fixedly connected to a main water delivery pipe 25. The main water delivery pipe 25 branches into a plurality of connecting branch pipes 26. One end of each of the plurality of connecting branch pipes 26 away from the main water delivery pipe 25 is communicated with a through hole 56. The plurality of through holes 56 are respectively arranged inside a plurality of wetting frames 525.

[0057] Through the provided platform assembly 2 and through holes 56, when the temperature of the voltage transformation device 4 is relatively high and auxiliary cooling is required, the water pump 22 is operated. The water pump 22 will pump the water inside the water storage platform 21 through the main water delivery pipe 25 and connecting branch pipes 26, and input it into the wetting frame 525 through the through holes 56. Moreover, when it rains, the rainwater collected by the top cover 3 will be discharged into the water storage platform 21 through the vertical grooves 24, which helps to save water resources. In addition, the external connecting pipe 23 connected to the water storage platform 21 can directly access the water source from the outside to timely supplement the water volume in the water storage platform 21 and ensure the normal operation of the entire system.

[0058] During use and operation, the voltage transformation device 4 is placed in the middle position of the outer shell 1. Ventilation slots are provided on both the front and rear surfaces of the outer shell 1, and these ventilation slots are used for ventilation and heat dissipation of the voltage transformation device 4. In addition, adjustable adjustment mechanisms 5 are provided on both sides of the outer shell 1. This mechanism can make corresponding adjustments according to the actual temperature of the voltage transformation device 4. When the temperature of the voltage transformation device 4 is relatively high and auxiliary cooling is required, the platform assembly 2 will input water into the wetting frame 525 through the through holes 56. After the water in the wetting frame 525 is full, the water will flow through the water permeable plate 526 into the sand storage cylinder 527, gradually wetting the sand in the sand storage cylinder 527, and the moisture will spread upward. At this time, the sealing plate 543 in the ventilation slot 544 is in the open state, and the heat dissipated by the voltage transformation device 4 will pass through the ventilation slot 544 and enter the wetted sand storage cylinder 527 through the breathable membrane 529. Since sand has good thermal conductivity, it can adsorb heat and take away a large amount of heat with the evaporation of moisture. At the same time, the water pump 22 continuously pumps water, ensuring the continuity of the cooling process and effectively playing the role of auxiliary cooling. When the temperature of the voltage transformation device 4 is relatively low and heat preservation is required, the driving assembly 53 is operated to drive a plurality of first driving gears 522 and second driving gears 542 to rotate. Among them, the first driving gear 522 drives the support block 521 and the wetting frame 525 to rotate 54° through the first driving shaft 524 and the connecting rod 523. This rotation makes the hypotenuses of a plurality of sand storage cylinders 527 connected to form a plane parallel to the protection net 51, thereby enhancing the resistance to external impacts. Moreover, after the water in the wetted sand evaporates, the remaining sand can also slow down the heat dissipation to a certain extent, helping to maintain the temperature inside the box in a low-temperature environment. At the same time, the second driving gear 542 drives the sealing plate 543 to rotate 90° in the ventilation slot 544 through the second driving shaft 541, making the sealing plate 543 completely seal the ventilation slot 544, effectively reducing heat dissipation and playing the role of closed heat preservation. In addition, when the sand storage cylinder 527 rotates, the stirring block 552 inside it will move upward under the traction of the connecting rope 551, driving part of the sand to move upward. When the sand storage cylinder 527 returns to its original position, the stirring block 552 will move downward and reset under the combined action of the telescopic spring 553 and the gravity block 554. In this way, the sand in the sand storage cylinder 527 is stirred to prevent the sand from caking and ensuring the uniformity of heat dissipation and heat absorption.

[0059] Working principle of the present invention:

[0060] During operation, the voltage transformation device 4 is placed at the middle position of the outer shell 1. Ventilation slots are provided on both the front and rear surfaces of the outer shell 1 for ventilation and heat dissipation of the voltage transformation device 4. In addition, adjustable adjustment mechanisms 5 are provided on both sides of the outer shell 1, and this mechanism can make corresponding adjustments according to the actual temperature condition of the voltage transformation device 4.

[0061] When the temperature of the voltage transformation device 4 is relatively high and auxiliary cooling is required, the water pump 22 is operated. The water pump 22 will pump the water inside the water storage platform 21 through the main water delivery pipe 25 and the connecting branch pipes 26, and input it into the wetting frame 525 through the through holes 56. After the water in the wetting frame 525 is full, the water will flow through the water permeable plate 526 into the sand storage cylinder 527, making the sand in the sand storage cylinder 527 gradually get wet, and the moisture will spread upward.

[0062] At this time, the sealing plate 543 in the ventilation slot 544 is in an open state. The heat dissipated by the voltage transformation device 4 will pass through the ventilation slot 544 and enter the wetted sand storage cylinder 527 through the breathable film 529. Since the sand has good thermal conductivity, it can adsorb heat and take away a large amount of heat with the evaporation of moisture. At the same time, the water pump 22 continuously supplies water, ensuring the continuity of the cooling process and effectively playing the role of auxiliary cooling.

[0063] When the temperature of the voltage transformation device 4 is relatively low and heat preservation is required, the rotating cylinder 531 is operated. The output shaft of the rotating cylinder 531 drives two threaded rods 533 to rotate simultaneously inside two double-sided racks 534 through the synchronous transmission belt 532. Subsequently, the two double-sided racks 534 will slide in the corresponding rack seats 535, thereby driving a plurality of first driving gears 522 and second driving gears 542 to rotate.

[0064] Among them, the first driving gear 522 drives the support block 521 and the wetting frame 525 to rotate 54° through the first driving shaft 524 and the connecting rod 523. This rotation makes the hypotenuses of a plurality of sand storage cylinders 527 connected to form a plane parallel to the protection net 51, thereby enhancing the resistance to external impacts. And after the water in the wetted sand evaporates, the remaining sand can also slow down the heat dissipation to a certain extent, helping to maintain the temperature inside the box in a low-temperature environment.

[0065] Meanwhile, the second driving gear 542 drives the sealing plate 543 to rotate 90° in the ventilation slot 544 through the second driving shaft 541, so that the sealing plate 543 completely seals the ventilation slot 544, effectively reducing heat dissipation and playing the role of closed heat preservation.

[0066] In addition, when the sand storage cylinder 527 rotates, the stirring block 552 inside it will move upward under the traction of the connecting rope 551, driving part of the sand to move upward. When the sand storage cylinder 527 resets, the stirring block 552 will move downward and reset under the combined action of the telescopic spring 553 and the gravity block 554. In this way, the sand in the sand storage cylinder 527 is stirred to prevent the sand from caking, ensuring the uniformity of heat dissipation and heat absorption.

[0067] It is worth mentioning that the top cover 3 has the function of rainwater collection. When it rains, the rainwater collected by the top cover 3 will be discharged into the water storage platform 21 through the vertical groove 24, which helps to save water resources. In addition, the external connecting pipe 23 connected to the water storage platform 21 can directly access the water source from the outside to timely supplement the water volume in the water storage platform 21 and ensure the normal operation of the entire system.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
