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 changes, resulting in unstable output voltage, which affects the normal operation of equipment and product quality. In addition, temperature changes can also accelerate the aging of internal components of the transformer, reducing its service life and increasing maintenance costs. 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] A patent with the publication number CN220873397U discloses an automatic temperature control box-type transformer, 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 multiple heat sinks are arranged on the tops of the support blocks on both left and right sides. By detecting the internal temperature with a detector and transmitting the information to the controller, the power of the first water pump can be controlled to adjust the speed of oil circulation, thereby taking away more or less heat inside the transformer body. By adjusting the power of the electric fan, the air flow rate can be controlled, thereby controlling 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 an appropriate temperature.

[0004] The existing technology has the following defects: 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 consumes a large amount of electric energy after long-term use. Oil cooling requires the operation of an oil pump and a 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.

[0005] 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 of the temperature inside the box, affecting the performance and lifespan of the transformer, and even potentially causing failures. 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 needs to be set up to make the temperature distribution inside the box more uniform, improve the power usage stability, and meet the high-precision power usage requirements of industrial equipment. Summary of the Invention

[0006] 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 usage requirements of industrial equipment is proposed.

[0007] This application provides a constant-temperature box-type transformer for high-precision power usage 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 the 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 usage requirements of industrial equipment.

[0008] The technical solution of the present invention is: A constant-temperature box-type transformer for high-precision power usage 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 keeps the voltage transformation device at a constant temperature 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; 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 jointly 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.

[0009] With the above - mentioned solution, through the provided sand - storage component, 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 to form 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.

[0010] Further, 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.

[0011] With the above - mentioned solution, through the provided first driving gear and driving shaft, 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.

[0012] Further, 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.

[0013] Further, 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.

[0014] With the above - mentioned solution, through the provided stirring component, 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.

[0015] Further, 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 formed in 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.

[0016] With the above solution, through the set sealing component, when the temperature of the voltage transformation equipment is relatively high and auxiliary cooling is required, the sealing plate in the ventilation groove is in an open state. When the temperature of the voltage transformation equipment is relatively low and heat preservation is required, the second driving gear drives the sealing plate to rotate 90° in the ventilation groove through the second driving shaft, so that the sealing plate completely seals the ventilation groove, effectively reducing heat dissipation and playing a role in closing and heat preservation.

[0017] 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 respectively meshed with a plurality of first driving gears and a plurality of second driving gears.

[0018] 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.

[0019] With the above 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.

[0020] 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.

[0021] 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 delivery pipe. The main water delivery pipe is branched into a plurality of connecting branch pipes. One ends of the plurality of connecting branch pipes away from the main water delivery pipe are all communicated with through holes, and the plurality of through holes are respectively arranged inside a plurality of wetting frames.

[0022] With the above solution, through the set platform component and through holes, when the temperature of the voltage transformation equipment 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 delivery pipe and the connecting branch pipes and input it into the wetting frames through the 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.

[0023] The beneficial effects of the present invention: Through 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 delivery pipe and connecting branch pipes, and input it 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. 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 pumps water, ensuring the continuity of the cooling process and effectively playing an auxiliary cooling role.

[0024] Through 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 a plurality of 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 makes the hypotenuses of a plurality of sand storage cylinders connected to form a plane parallel to the protection net, thus 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. 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.

[0025] Through 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 resets, 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 ensure the uniformity of heat dissipation and heat absorption. Description of the Drawings

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings of the specification.

[0029] 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 an outer shell 1, a platform component 2 fixedly installed at the bottom of the outer shell 1, a top cover 3 fixedly installed on the top of the outer shell 1, an adjusting mechanism 5 fixedly installed inside the frame of the outer shell 1, and a voltage transformation equipment 4 located in the middle of the outer shell 1. The adjusting mechanism 5 maintains the constant temperature of the voltage transformation equipment 4 through adjustment. The top cover 3 is used to collect rainwater, the platform component 2 is used to store water, the adjusting mechanism 5 includes a protection net 51, a sand storage component 52, and a sealing component 54 provided inside the frame of the outer shell 1, a driving component 53 provided above the sand storage component 52 and the sealing component 54, and a stirring component 55 provided inside the sand storage component 52.

[0030] 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 bottom of the three support rods 528 is 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.

[0031] 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 vertices, 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.

[0032] 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 platform 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, so that the sand in the sand storage cylinder 527 is gradually wetted, and the moisture will spread upward. The heat dissipated by the voltage transformation device 4 enters the wetted 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, forming a plane parallel to the protection net 51, thereby enhancing the resistance to external impacts. And after the moisture of the wetted 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.

[0033] Refer to Figure 5 , the sand storage component 52 further includes a first driving shaft 524 rotatably connected to the inner wall of the housing 1. Connecting rods 523 are fixedly connected between the first driving shaft 524 and the support block 521 and the wetting frame 525 respectively. A first driving gear 522 is fixedly connected to the outer wall of the first driving shaft 524.

[0034] Through the arranged first driving gear 522 and first driving shaft 524, the first driving gear 522 can drive the support block 521 and the wetting frame 525 to rotate through the first driving shaft 524 and the connecting rod 523, playing a role in adjusting the shape.

[0035] 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.

[0036] Specifically, one end of the connecting rope 551 above is fixed to the inner wall of the housing 1, and the other end below is connected to the gravity block 554 to slide 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 returns to its original position, 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.

[0037] 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 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 ensure the uniformity of heat dissipation and heat absorption.

[0038] 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.

[0039] Through the arranged sealing assembly 54, when the temperature of the voltage transformation device 4 is relatively high and auxiliary cooling is required, the sealing plate 543 in the ventilation groove 544 is in an open state. When the temperature of the voltage transformation device 4 is relatively low and heat preservation is required, the second drive gear 542 drives the sealing plate 543 to rotate 90° in the ventilation groove 544 through the second drive shaft 541, so that the sealing plate 543 completely seals the ventilation groove 544, effectively reducing heat dissipation and playing a role in sealing and heat preservation.

[0040] Refer to Figure 7 - Figure 8, the driving assembly 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 engaged 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 drive 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.

[0041] By providing the driving assembly 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 drive belt 532. Subsequently, the two double-sided racks 534 will slide in the corresponding rack seats 535, thereby driving the rotation of a plurality of first driving gears 522 and second driving gears 542, playing a role in providing power.

[0042] Refer to Figure 9 - Figure 11 , the platform assembly 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 is communicated 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 is branched 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.

[0043] By providing the platform assembly 2 and the 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 the connecting branch pipes 26, and input it into the wetting frames 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 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 water from the outside to timely supplement the water volume in the water storage platform 21 and ensure the normal operation of the entire system.

[0044] During operation, the voltage transformation device 4 is placed in the middle of the outer casing 1. Ventilation slots are provided on both the front and rear surfaces of the outer casing 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 casing 1, and 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 inputs water into the soaking frame 525 through the through hole 56. After the water in the soaking frame 525 is full, the water will flow through the water permeable plate 526 into the sand storage cylinder 527, gradually soaking 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 an open state, and the heat dissipated by the voltage transformation device 4 will pass through the ventilation slot 544 and enter the soaked sand storage cylinder 527 through the breathable membrane 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 an auxiliary cooling role. When the temperature of the voltage transformation device 4 is relatively low and heat preservation is required, the operation drive assembly 53 drives a plurality of first drive gears 522 and second drive gears 542 to rotate. Among them, the first drive gear 522 drives the support block 521 and the soaking frame 525 to rotate 54° through the first drive 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 protective net 51, thereby 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. At the same time, the second drive gear 542 drives the sealing plate 543 to rotate 90° in the ventilation slot 544 through the second drive shaft 541, making the sealing plate 543 completely seal the ventilation slot 544, effectively reducing heat dissipation and playing a role in 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.

[0045] Working principle of the present invention: During operation, the voltage transformation device 4 is placed in the middle of the outer casing 1. Ventilation slots are provided on both the front and rear surfaces of the outer casing 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 casing 1, and this mechanism can make corresponding adjustments according to the actual temperature of the voltage transformation device 4.

[0046] 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 pipe 25 and the connecting branch pipe 26, and input it into the wetting frame 525 through the through hole 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.

[0047] At this time, the sealing plate 543 in the ventilation groove 544 is in the open state. The heat dissipated by the voltage transformation device 4 will pass through the ventilation groove 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.

[0048] 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 bilateral racks 534 through the synchronous transmission belt 532. Subsequently, the two bilateral racks 534 will slide in the corresponding rack seats 535, thereby driving a plurality of first drive gears 522 and second drive gears 542 to rotate.

[0049] Among them, the first drive gear 522 drives the support block 521 and the wetting frame 525 to rotate 54° through the first drive shaft 524 and the connecting rod 523. This rotation causes the hypotenuses of a plurality of sand storage cylinders 527 to be connected, forming a plane parallel to the protective 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.

[0050] At the same time, the second drive gear 542 drives the sealing plate 543 to rotate 90° in the ventilation groove 544 through the second drive shaft 541, making the sealing plate 543 completely seal the ventilation groove 544, effectively reducing heat dissipation and playing the role of closed heat preservation.

[0051] 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 ensure the uniformity of heat dissipation and heat absorption.

[0052] 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 whole 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 within the scope of the claims of the present invention.
