Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a prefabricated non-metallic cabin. Background Technology

[0002] Currently, with the increasing scarcity of urban land, prefabricated substations are being widely used. Existing prefabricated substations are generally made by assembling metal skins onto a main frame. The electrical equipment in a prefabricated substation is centrally located within the prefabricated substation, which, compared to traditional concrete substations, features a compact structure, small size, convenient transportation, and easy assembly.

[0003] Existing prefabricated cabins have several shortcomings: First, it's inconvenient to reserve space for future equipment installation. When large equipment is brought in, wall panels typically need to be dismantled. Furthermore, when equipment enters from the side, it's crucial to avoid collisions between the hoisting ropes and the cabin structure. Usually, the equipment is simply hoisted at the entrance and then lifted into the cabin by personnel, which is quite laborious. Second, the equipment inside the prefabricated cabin generates significant heat, especially in hot summer weather. The high internal temperature is detrimental to stable equipment operation. Moreover, due to varying heat output from different equipment areas, temperatures differ between zones. Existing prefabricated cabins only rely on air conditioning for overall internal cooling, failing to provide zoned cooling based on the actual temperature of each area, resulting in insufficient temperature control. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a prefabricated, non-metallic cabin with a sliding, openable roof for easy equipment installation and reduced labor requirements. Furthermore, heat dissipation structures are incorporated into the cabin's support columns, allowing for zoned temperature control based on the specific area's temperature, thus enhancing overall temperature management.

[0005] The present invention is achieved through the following technical solution: a prefabricated non-metallic cabin, including a cabin body and a cabin roof. The cabin body includes a bottom plate, and main columns are fixedly connected to the four corners of the top surface of the bottom plate. The top of the four main columns jointly supports a top beam frame. Multiple support columns are provided between two adjacent main columns. The upper and lower ends of the support columns are fixedly connected to the top beam frame and the bottom plate, respectively. Composite wall components are fixedly connected between the support columns and the main columns, as well as between adjacent support columns. The top of the cabin includes two sliding covers arranged opposite each other. The two sliding covers are distributed along the width of the cabin and extend along the length of the cabin and are slidably connected to the top beam frame. The cabin is provided with a drive mechanism that drives the two sliding covers to slide closer or further apart. When the two sliding covers are close to each other, the top opening of the cabin is closed. When the two sliding covers are far apart, the top opening of the cabin is opened.

[0006] As an optimization, the sliding top cover includes multiple support frames and a cover plate. The multiple support frames are arranged along the length of the cabin, and adjacent support frames are fixedly connected by connecting rods. The top surface of the support frame is an inclined surface, and the cover plate is fixedly connected to the inclined surface of the support frame and covers the multiple support frames inside. The bottom surface of the support frame is a flat surface, and two of the support frames are fixedly connected to slide rails on their bottom surfaces. The top of the top beam frame is fixedly connected to two guide rails, and the two slide rails slide in cooperation with the two guide rails one by one.

[0007] As an optimization, the lower inclined ends of the top surfaces of the two sliding top covers are far apart from each other, and an arc-shaped baffle is fixed to the upper inclined end of the top surface of one of the sliding top covers. The arc-shaped baffle extends along the length of the sliding top cover. When the two sliding top covers approach and contact each other, the arc-shaped baffle blocks the gap between the two sliding top covers.

[0008] As an optimization, the drive mechanism includes two spur racks, two spur gears, two driven bevel gears, and two driving bevel gears. The two spur racks are respectively fixed to the support frames of the two sliding cover plates. The two spur gears mesh with the two spur racks respectively. The spur gears are fixed to a rotating shaft, which is rotatably connected to the side wall of the top beam frame. The two driving bevel gears are respectively fixed to the two rotating shafts. A transmission shaft is also rotatably mounted on the side wall of the top beam frame. The two driven bevel gears are respectively fixed to both ends of the transmission shaft and mesh with the two driving bevel gears respectively.

[0009] As an optimization, the number of drive mechanisms is two sets, with the two drive mechanisms located on both sides of the length direction of the top beam frame. The two rotating shafts of the two drive mechanisms are fixedly connected by a coupling, and a drive motor for driving the coupling to rotate is fixed on the cabin.

[0010] As an optimization, the support column is a hollow structure with closed upper and lower ends. A ventilation fan is fixed on the upper end of the side wall of the support column facing the outside of the cabin. The ventilation fan is connected to the inner cavity of the support column. A long heat dissipation hole is opened on the upper part of the side wall of the support column facing the inside of the cabin. The long heat dissipation hole extends vertically from top to bottom and its length is 1 / 4 to 1 / 3 of the length of the support column. The support column is equipped with a sliding plug that slides up and down. The outer diameter of the plug is adapted to the inner diameter of the support column. The length of the plug is greater than the length of the elongated heat dissipation hole. A spring is installed in the inner cavity of the support column below the plug. A temperature-sensing propulsion mechanism is fixed to the side wall of the support column facing the interior of the cabin. The temperature-sensing propulsion mechanism is used to sense the temperature inside the cabin and drive the plug to slide down to compress the spring.

[0011] As an optimization, the temperature-sensing propulsion mechanism includes an upper fixed plate and a lower fixed plate fixed to the side wall of the support column. The upper and lower fixed plates are located below the elongated heat dissipation holes and are arranged opposite each other. A guide rod is fixed between the upper and lower fixed plates. An elastic telescopic tube and a sliding plate are sleeved on the guide rod. The upper end of the elastic telescopic tube is sealed and fixed to the upper fixed plate, and the lower end of the elastic telescopic tube is sealed and fixed to the sliding plate. The elastic telescopic tube is filled with thermal expansion fluid. The sliding plate is connected and fixed to the lower end of the blocking column through a connecting block. An elongated sliding hole is opened on the side wall of the support column for the connecting block to pass through and move up and down. A temperature-sensing and heat-conducting probe is fixed on the upper fixed plate and inserted into the thermal expansion fluid.

[0012] As an optimization, the cabin is equipped with two rows of air ducts that extend along the length of the cabin. The two rows of air ducts are located on both sides of the width of the cabin. The bottom of the air ducts is equipped with multiple air outlets. The number of air outlets is the same as the number of support columns along the length of the cabin and corresponds one-to-one. Each air outlet is equipped with an air conditioning splitter and an electric gate.

[0013] As an optimization, the temperature-sensing heat conduction probe is connected to a temperature monitor, which is connected to a controller. The ventilation fan and the electric gate are both connected to the controller, which is used to control and adjust the speed of the ventilation fan and the opening amount of the electric gate.

[0014] The beneficial effects of this invention are as follows: 1. The top of the cabin in this design consists of two sliding covers. A drive mechanism moves these covers relative to each other, opening and closing the top of the cabin. When the two covers move away from each other, the top opening of the cabin is open. During subsequent equipment installation, the equipment can be directly hoisted into the cabin through this opening for placement and installation, eliminating the need for personnel to lift the equipment inside, significantly reducing labor and making it easier to accommodate future equipment. After the equipment is inside, simply bringing the two sliding covers together closes the top opening of the cabin, making it convenient to use.

[0015] 2. When the two sliding top covers approach each other, their ends come into contact and fit together through sealing gaskets, greatly improving the sealing performance after docking. The upper arc-shaped baffle further enhances rainproofing, preventing rainwater from seeping into the cabin through gaps and ensuring internal electrical safety.

[0016] 3. The drive mechanism causes the rotating shaft to drive the spur gear to rotate, which in turn drives the spur rack to move, causing the sliding top cover to slide. At the same time, the driving bevel gears on the rotating shafts of the two sliding top covers are linked through the driven bevel gears on the transmission shaft. When the rotating shaft of one sliding top cover rotates, it can drive the rotating shaft of the other sliding top cover to rotate synchronously in the opposite direction, thus causing the two sliding top covers to move relative to each other.

[0017] 4. The two sliding top covers are driven by two sets of drive mechanisms, which are distributed on both sides and connected by a coupling. In this way, the two sets of drive mechanisms can be synchronized by a single motor, saving energy consumption and making the sliding of the two sliding top covers more stable.

[0018] 5. This solution integrates a temperature-regulating structure within each support column. This structure on each column regulates the temperature of the corresponding area, saving space and improving zoned temperature control. During temperature control, a temperature-sensing probe detects the temperature and directs heat into the thermal expansion fluid. The fluid expands due to heat, causing the elastic telescopic tube to elongate, which in turn pushes the sliding plate downwards, causing the blocking column to slide downwards, gradually enlarging the opening of the elongated heat dissipation holes. The larger the opening of the elongated heat dissipation holes, the more efficiently heat can be dissipated. When the temperature decreases, the thermal expansion fluid contracts, and the blocking column slides upwards under the push of the spring, gradually closing the elongated heat dissipation holes, thus adjusting the heat dissipation effect according to the temperature of each area.

[0019] 6. After sensing the temperature, the heat-conducting temperature probe transmits the temperature value to the temperature monitor for processing. The controller then adjusts the speed of the ventilation fan on the corresponding support column. When the temperature is high, the speed is increased to accelerate ventilation and heat dissipation. At the same time, the opening amount of the electric gate is controlled. When the temperature is high, the opening amount is increased to allow more cool air to be discharged, thereby improving the cooling effect of the corresponding area. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figures 1-17 As shown, a prefabricated non-metallic cabin includes a cabin body 1 and a cabin roof 2. The cabin body 1 includes a base plate 11, and main columns 12 are fixedly connected to the four corners of the top surface of the base plate 11. The tops of the four main columns 12 jointly support a top beam frame 13. Multiple support columns 14 are provided between two adjacent main columns 12. The upper and lower ends of the support columns 14 are fixedly connected to the top beam frame 13 and the base plate 11, respectively. Composite wall components 16 are fixedly connected between the support columns 14 and the main columns 12, as well as between adjacent support columns 14.

[0023] like Figure 1As shown, specifically, the base plate 11 is a rectangular plate structure. The top beam frame 13 is a rectangular frame structure. The upper ends of the four main columns 12 are fixed to the four bottom corners of the top beam frame 13 of the rectangular frame. In this embodiment, the upper ends of the main columns 12 and the top beam frame 13, as well as the lower ends of the main columns 12 and the base plate 11, are detachably fixed using angle bracket bolts for easy assembly.

[0024] like Figure 1 As shown, in this embodiment, five support columns 14 are arranged between two adjacent main columns 12 along the length direction, and two support columns 14 are arranged between two adjacent main columns 12 along the width direction. The upper end of the support column 14 is detachably fixed to the top beam frame 13, and the lower end of the support column 14 is fixed to the bottom plate 11 by means of angle bracket bolts, which facilitates assembly. Furthermore, a door frame is fixed between two of the five support columns 14 located on the front side of the cabin 1, and a hatch 15 is installed on the door frame.

[0025] like Figure 3 , 6 As shown in Figures 7 and 8, the composite wall assembly 16 is a non-metallic composite wall assembly. Specifically, the composite wall assembly 16 includes an inner wall panel 162, an outer wall panel 161, an insulation layer 163, and a transverse reinforcing beam 164. The reinforcing beam 164 is detachably fixed at both ends to the middle of the support column 14 and the upright column, or between the middle of adjacent support columns 14, using angle bracket bolts for easy assembly. The inner wall panel 162 and the outer wall panel 161 are respectively fixed to the inner and outer sides of the reinforcing beam 164 using self-tapping screws. The insulation layer 163 fills the space between the inner wall panel 162 and the outer wall panel 161 and is fixed using self-tapping screws. During assembly, the reinforcing beam 164 is installed first, then the inner wall panel 162 is fixed to the reinforcing beam 164. Next, the insulation layer 163 is placed within the upper and lower frames of the reinforcing beam 164. Then, the outer wall panel 161 is fixed to the reinforcing beam 164 to form the composite wall assembly 16. Finally, the upper and lower ends of the composite wall assembly 16 are fixed to the top beam frame 13 and the bottom plate 11 respectively using angle bracket bolts to enhance stability. After installation, weather-resistant sealant is filled at the joints to enhance sealing and greatly improve assembly efficiency.

[0026] The exterior wall panel 161 of this non-metallic composite wall component uses 10mm thick fiber-reinforced calcium silicate board, which has UV resistance, corrosion resistance, and impact resistance. The insulation layer 163 is 80mm thick B1-grade flame-retardant polyurethane foam, providing excellent thermal insulation performance. The interior wall panel 162 is a 6mm thick fire-resistant board (with calcium silicate board as the base material, and the surface of the base material is covered with a fireproof skin, a UV penetrating layer, and a PUR hot-melt layer).

[0027] like Figure 6 , 7As shown in Figure 8, the top of the cabin 2 includes two sliding top covers 21 arranged opposite each other. The two sliding top covers 21 are distributed along the width direction of the cabin body 1 and extend along the length direction of the cabin body 1 and are slidably connected to the top beam frame 13. The cabin body 1 is provided with a drive mechanism 3 that drives the two sliding top covers 21 to slide closer or further apart. When the two sliding top covers 21 are close to each other, the top opening of the cabin body 1 is closed; when the two sliding top covers 21 are far apart, the top opening of the cabin body 1 is opened.

[0028] like Figure 4 As shown, specifically, the sliding top cover 21 includes multiple support frames 211 and a cover plate 212. The multiple support frames 211 are arranged along the length of the cabin 1, and adjacent support frames 211 are fixedly connected by connecting rods 213. The multiple support frames 211 are connected into a whole by connecting rods 213, resulting in higher structural strength. The top surface of the support frame 211 is a slope, and the cover plate 212 is fixedly connected to the slope of the support frame 211 and covers the multiple support frames 211 inside. The bottom surface of the support frame 211 is a plane, and two support frames 211 have slide rails 214 fixedly connected to their bottom surfaces. The top of the top beam frame 13 has two guide rails 131 fixedly connected to its top, and the two slide rails 214 slide in cooperation with the two guide rails 131.

[0029] like Figure 4 As shown, in this embodiment, the support frame 211 has a right-angled trapezoidal structure. The vertical side of the right-angled trapezoid is the base of the support frame 211, and the inclined side is the top surface of the support frame 211. The cover plate 212 also has a right-angled trapezoidal cross-section, thus enclosing multiple support frames 211 inside. The inclined lower ends of the top surfaces of the two sliding top covers 21 are far apart from each other, while the inclined upper ends of the top surfaces of the two sliding top covers 21 are close to each other. This allows rainwater to be discharged outward through the two inclined surfaces.

[0030] like Figure 4 , 11 As shown, preferably, an arc-shaped baffle 23 is fixed to the inclined upper end of the top surface of one of the sliding top covers 21, and the arc-shaped baffle 23 extends along the length direction of the sliding top cover 21. When the two sliding top covers 21 approach and contact each other, the arc-shaped baffle 23 blocks the gap between the two sliding top covers 21.

[0031] like Figure 4 , 11As shown, preferably, sealing gaskets 22 are also provided on the end faces of the two sliding top covers 21 that are close to each other. That is, the sealing gaskets 22 are fixed to the side wall of the cover plate 212, and the sealing gaskets 22 are rubber gaskets. When the two sliding top covers 21 are close to each other, the sealing gaskets 22 at the ends of the two sliding top covers 21 contact and fit together, which greatly improves the sealing performance after the two sliding top covers 21 are joined. Furthermore, the arc-shaped baffle 23 above blocks the gap between the two, further improving the rainproof performance and preventing rainwater from seeping into the interior of the cabin 1 from the gap between the two, thus ensuring the safety of internal electrical use.

[0032] like Figure 4 , 5 As shown, in this embodiment, the bottom of the two outermost support frames 211 of each sliding top cover 21 is fixedly connected to the slide rail 214. The length of the slide rail 214 is the same as the bottom length of the support frame 211, and the distance between the two outermost support frames 211 is the same as the length of the top beam frame 13. Figure 1 , 2 As shown, in this embodiment, the top of the two wide sides of the rectangular top beam frame 13 is fixedly connected to the guide rail 131, and the length of the guide rail 131 is the same as the width of the top beam frame 13. The guide rail 131 is a T-shaped guide rail 131, and the bottom of the slide rail 214 is provided with a T-shaped groove that matches the T-shaped guide rail 131. The T-shaped guide rail 131 is slidably engaged in the T-shaped groove, so that the slide rail 214 slides along the guide rail 131, thereby realizing the sliding connection between the sliding top cover 21 and the top beam frame 13. The two sliding top covers 21 slide in opposite directions through the drive mechanism 3. Figure 9 As shown, there are two sets of drive mechanisms 3. The two sets of drive mechanisms 3 are located on both sides of the length direction of the top beam frame 13, that is, the two sets of drive mechanisms 3 are respectively set on the two wide side walls of the rectangular top beam frame 13. The two sets of drive mechanisms 3 drive the two ends of the two sliding top covers 21 to move simultaneously, ensuring the stability of sliding.

[0033] like Figure 10 , 12As shown in Figures 13 and 15, specifically, the drive mechanism 3 includes two racks 31, two spur gears 32, two driven bevel gears 35, and two driving bevel gears 34. The two racks 31 are respectively fixed to the support frames 211 of the two sliding covers, with the teeth of the racks 31 facing downwards. The racks 31 extend along the width direction of the top beam frame 13, and their length is less than the length of the support frame 211. The two spur gears 32 mesh with the two racks 31 respectively. A rotating shaft 33 is fixed to each spur gear 32, and the rotating shaft 33 is rotatably connected to the side wall of the top beam frame 13 via bearings. The two spur gears 32 are located at opposite ends of the top beam frame 13 in the width direction. The rotating shaft 33 drives the spur gears 32 to rotate, thereby driving the meshing racks 31 to move along the width direction, causing the sliding top cover 21 to slide along the width direction. Since the spur gears 32 are located at the ends of the top beam frame 13 in the width direction, the sliding top cover 21 can be opened outwards to its maximum extent. As can be imagined, limiting plates can be set at both ends of the rack 31 to prevent the rack 31 from disengaging from the spur gear 32. The two sliding top covers 21 can slide independently through the cooperation of their respective racks 31 and spur gears 32.

[0034] like Figure 10 , 12 As shown in Figure 13, furthermore, two driving bevel gears 34 are respectively fixedly connected to two rotating shafts 33, that is, the two driving bevel gears 34 are respectively coaxially arranged with two spur gears 32. A drive shaft 36 is also rotatably mounted on the wide side wall of the top beam frame 13. The drive shaft 36 extends along the width direction of the top beam frame 13, that is, the drive shaft 36 is parallel to the spur rack 31. Two driven bevel gears 35 are respectively fixedly connected to both ends of the drive shaft 36, and the two driven bevel gears 35 mesh with the two driving bevel gears 34 respectively. The rotating shafts 33 corresponding to the two sliding top covers 21 are linked through the cooperation of the drive shaft 36, the driven bevel gears 35 and the driving bevel gears 34, so that the two independently sliding sliding top covers 21 form an integral linkage structure. When the shaft 33 of one of the sliding top covers 21 rotates, it drives the driving bevel gear 34 and the driven bevel gear 35 on the shaft 33 to rotate, which in turn drives the transmission shaft 36 to rotate, and finally drives the shaft 33 of the other sliding top cover 21 to rotate synchronously in opposite directions, so that the two sliding top covers 21 slide closer to each other or further away from each other.

[0035] like Figure 9 , 14As shown in Figure 15, since only one sliding cover 21 needs to be driven to move, the other sliding cover 21 can be driven synchronously, so only one drive motor 5 is needed. To ensure that the two sets of drive mechanisms 3 can move synchronously, in this embodiment, the two opposing rotating shafts 33 of the two sets of drive mechanisms 3 are fixedly connected by a connecting shaft 4, and the drive motor 5 that drives the connecting shaft 4 to rotate is fixedly installed on the cabin 1. That is, the corresponding rotating shafts 33 at both ends of one sliding cover 21 are fixedly connected as one unit by the connecting shaft 4. In this way, by driving the connecting shaft 4 to rotate by the drive motor 5, the rotating shafts 33 at both ends of the connecting shaft 4 can rotate synchronously, so that the corresponding sliding cover 21 slides. In this embodiment, the connecting shaft 4 is rotatably connected to the long side wall of the top beam frame 13, and a driven sprocket is fixedly connected to the center of the connecting shaft 4. The drive motor 5 is fixedly installed on the inner wall of the cabin 1, and a driving sprocket is fixedly connected to the output end of the drive motor 5. The driving sprocket and the driven sprocket are connected by chain drive.

[0036] The top of the cabin 2 consists of two sliding covers 21. A drive mechanism 3 drives the two sliding covers 21 to slide relative to each other, opening or closing the top of the cabin 1. When the two sliding covers 21 move away from each other, the top opening of the cabin 1 is open. When equipment is later installed, it can be directly hoisted into the cabin 1 through the top opening for placement and installation, eliminating the need for personnel to lift the equipment into the cabin, greatly reducing labor and making it more convenient to install future equipment. After the equipment is installed, simply bringing the two sliding covers 21 together close together closes the top opening of the cabin 1, making it easy to use.

[0037] like Figure 17 As shown, the support column 14 is a hollow structure, with its upper and lower ends closed. A ventilation fan 6 is fixed to the upper part of the side wall of the support column 14 facing the outside of the cabin 1, and the ventilation fan 6 is connected to the inner cavity of the support column 14. An elongated heat dissipation hole 7 is formed on the upper part of the side wall of the support column 14 facing the inside of the cabin 1. The elongated heat dissipation hole 7 extends vertically from top to bottom and its length is 1 / 4 to 1 / 3 of the length of the support column 14. Utilizing the principle of hot air rising, heat can enter the interior of the support column 14 through the elongated heat dissipation hole 7, and then the heat inside the support column 14 is quickly discharged to the outside through the ventilation effect of the ventilation fan 6. In this embodiment, two elongated heat dissipation holes 7 are formed on the side wall of the support column 14 facing the inside of the cabin 1, allowing more heat to enter the support column 14.

[0038] like Figure 17 As shown, the support column 14 has a sliding plug 8 inside, the outer diameter of which matches the inner diameter of the support column 14, and the length of the plug 8 is greater than the length of the elongated heat dissipation hole 7. A spring 10 is installed inside the support column 14 below the plug 8, and the elastic force of the spring 10 is greater than the weight of the plug 8. A temperature-sensing propulsion mechanism 9 is fixed to the side wall of the support column 14 facing the interior of the cabin 1. The temperature-sensing propulsion mechanism 9 is used to sense the temperature and drive the plug 8 to slide downwards to compress the spring 10.

[0039] like Figure 17As shown, in this embodiment, the support column 14 is a rectangular tube, and the blocking column 8 is also a rectangular tube, with both the upper and lower ends of the blocking column 8 closed. The length of the blocking column 8 is twice the length of the elongated heat dissipation hole 7. Since the elastic force of the spring 10 is greater than the weight of the blocking column 8, the spring 10 will push the blocking column 8 upward in its natural state, causing the upper end of the blocking column 8 to contact the upper end of the support column 14. At this time, the blocking column 8 completely seals the elongated heat dissipation hole 7.

[0040] The temperature-sensing propulsion mechanism 9 utilizes the principle of thermal expansion and contraction. When the temperature is high, it expands, thus pushing the block downwards and compressing the spring 10. When the temperature decreases, it contracts, and the spring 10 elastically returns to its original position, pushing the block upwards. As the temperature-sensing propulsion mechanism 9 drives the block 8 downwards, the elongated heat dissipation hole 7 gradually opens, and the ventilation fan 6 connects with the inner cavity of the support column 14 above the block 8. Heat can then enter the inner cavity of the support column 14 above the block 8 through the elongated heat dissipation hole 7 and be quickly dissipated through the ventilation fan 6. Furthermore, as the block 8 gradually slides down, the opening of the elongated heat dissipation hole 7 increases, allowing more heat to enter simultaneously and resulting in faster heat dissipation.

[0041] like Figure 17 As shown, specifically, the temperature-sensing propulsion mechanism 9 includes an upper fixed plate 91 and a lower fixed plate 92 fixed to the side wall of the support column 14. The upper fixed plate 91 and the lower fixed plate 92 are located below the elongated heat dissipation hole 7 and are arranged vertically opposite each other. A guide rod 93 is fixed between the upper fixed plate 91 and the lower fixed plate 92. An elastic telescopic tube 94 and a sliding plate 95 are sleeved on the guide rod 93. The upper end of the elastic telescopic tube 94 is sealed and fixed to the upper fixed plate 91, and the lower end of the elastic telescopic tube 94 is sealed and fixed to the sliding plate 95. The elastic telescopic tube 94 is filled with thermal expansion fluid 96. The sliding plate 95 is connected and fixed to the lower end of the blocking column 8 through a connecting block. An elongated sliding hole 98 is opened on the side wall of the support column 14 for the connecting block to pass through and move up and down. A temperature-sensing and heat-conducting probe 97 is fixed on the upper fixed plate 91 and is inserted into the thermal expansion fluid 96.

[0042] In this embodiment, the length of the guide rod 93 is greater than the sum of the natural lengths of the elongated heat dissipation hole 7 and the elastic telescopic tube 94, and the length of the elongated sliding hole 98 is not less than the length of the elongated heat dissipation hole 7, so that the plug 8 has sufficient sliding allowance, thereby fully opening the elongated heat dissipation hole 7.

[0043] In this embodiment, when the upper end of the plug contacts the upper end of the support column 14, i.e., when the plug completely seals the elongated heat dissipation hole 7, the elastic expansion tube 94 is in its natural state, and at this time, the filling amount of the thermal expansion fluid 96 inside it is 100%. The upper and lower ends of the elastic expansion tube 94 are sealed. The elastic expansion tube 94 is preferably a metal corrugated pipe, which satisfies axial expansion and contraction while having radial strength to avoid radial deformation. The thermal expansion fluid 96 is preferably kerosene or mercury, which has a high coefficient of expansion.

[0044] Heat is transferred to the thermal expansion fluid 96 via the temperature-sensing heat conduction probe 97. The thermal expansion fluid 96 expands due to the heat, thereby pushing the slide plate 95 to slide downwards along the guide rod 93, which in turn causes the plug 8 to slide downwards, gradually opening the elongated heat dissipation hole 7. The higher the temperature, the greater the expansion of the thermal expansion fluid 96, the more the plug slides downwards, the greater the opening of the elongated heat dissipation hole 7, and the faster the heat dissipation.

[0045] like Figure 10 , 16 As shown, the cabin 1 has two rows of air ducts 200 extending along the length of the cabin 1. The two rows of air ducts 200 are located on both sides of the cabin 1 in the width direction, and each row of air ducts 200 is connected to an air conditioning unit 100. The bottom of each air duct 200 has multiple air outlets 300, the number of which corresponds to the number of support columns 14 along the length of the cabin 1. Each air outlet 300 is equipped with an air conditioning distributor (not shown in the figure) and an electric damper (not shown in the figure). The air conditioning distributor is used to distribute the cold air from the air ducts 200. The electric damper is an electric damper valve used to control the opening and closing of the air outlets 300.

[0046] Equipment such as transformers is typically installed in the middle of the cabin 1, thus forming corridors on both sides of the equipment. Therefore, the two rows of air ducts 200 are positioned above these corridors, i.e., on both sides of the equipment. When the equipment generates heat to both sides, the two rows of air ducts 200 cool and dissipate heat to each of the two corridors, resulting in better cooling. The air conditioning unit 100 supplies cool air to the air ducts 200, and each air outlet 300 distributes the cool air from the air ducts 200 through an air conditioning distributor. The opening amount of the air outlets 300 is controlled by an electric damper to regulate the amount of cool air output. The air conditioning unit 100, air conditioning distributor, and electric damper are all existing technologies and can be directly purchased and used.

[0047] In this embodiment, the temperature-sensing thermal conductivity probe 97 is connected to a temperature monitor (not shown in the figure), and the temperature monitor is connected to a controller. The ventilation fan 6 and the electric gate are both connected to the controller, which controls and adjusts the speed of the ventilation fan 6 and the opening amount of the electric gate. The temperature-sensing thermal conductivity probe 97 uses a PT100 temperature sensor probe, which has temperature sensing and thermal conductivity effects and transmits the temperature signal to the temperature monitor for processing. The temperature monitor can be a Tiankang XTRM series remote temperature monitor. The temperature monitor monitors the temperature change and transmits the signal to the controller, which then adjusts the speed of the ventilation fan 6 and the opening amount of the electric gate. The higher the temperature, the faster the speed of the ventilation fan 6 and the greater the opening amount of the electric gate, until the ventilation fan 6 reaches its maximum speed and stops, and the electric gate opens to its maximum stop. The control program of the controller is existing technology and was programmed and implemented by those skilled in the art; it will not be described in detail here.

[0048] like Figure 16 As shown, in this embodiment, since the cabin 1 has 5 support columns 14 along its length, each row of air ducts 200 has 5 air outlets 300. The temperature sensing and heat conduction probe 97 on each support column 14, its corresponding ventilation fan 6, and the electric gate on the corresponding air outlet 300 form an independent control program. The temperature adjustment between each support column 14 does not affect each other, thus achieving zoned temperature control.

[0049] This application integrates a blocking column 8 structure inside each support column 14 for temperature regulation, allowing for individual temperature adjustment of each area, saving space and enabling zoned temperature control. During temperature control, a temperature-sensing heat conduction probe 97 senses the temperature and directs the heat into the thermal expansion fluid 96. The thermal expansion fluid 96 expands due to heat, causing the elastic telescopic tube 94 to extend, which in turn pushes the sliding plate 95 downwards, causing the blocking column 8 to slide downwards, opening the elongated heat dissipation hole 7. Simultaneously, the temperature-sensing heat conduction probe 97 transmits the sensed temperature value to a temperature monitor for processing. The controller then adjusts the speed of the ventilation fan 6 on the corresponding support column 14; when the temperature is high, the speed is increased to accelerate ventilation and heat dissipation. Simultaneously, the opening amount of the electric gate is controlled; when the temperature rises, the opening amount is increased to expel more cold air, thereby improving the cooling effect of the corresponding area. When the temperature decreases, the thermal expansion fluid 96 contracts, and the blocking column 8 slides upwards under the push of the spring 10, gradually closing the elongated heat dissipation hole 7. This achieves automatic adjustment of the heat dissipation effect according to the area temperature.

[0050] Working principle: The support columns 14 on both sides of the length of the chamber 1 and the air outlets 300 of the side air ducts 200 work together to regulate and dissipate heat in the corresponding areas on both sides of the length of the equipment. The support columns 14 on both sides of the width of the chamber 1 regulate and dissipate heat in the corresponding areas on both sides of the width of the equipment, realizing zoned temperature regulation and heat dissipation in each area around the equipment. When the temperature inside the chamber begins to rise, the heat is transferred to the thermal expansion fluid 96 through the temperature-sensing heat conduction probe 97. The thermal expansion fluid 96 expands, causing the elastic telescopic tube 94 to extend, which in turn pushes the slide plate 95 down, thereby causing the blocking column 8 to slide down and open the long strip heat dissipation hole 7. The higher the heat, the larger the opening of the long strip heat dissipation hole 7. At the same time, the temperature-sensing heat conduction probe 97 transmits the temperature signal to the temperature monitor. The temperature monitor transmits the signal to the controller based on the temperature change. The controller controls the corresponding ventilation fan 6 to increase its speed and the opening amount of the electric damper on the corresponding air outlet 300. The ventilation fan 6 accelerates to expel the hot air entering the support column 14. At the same time, the opening amount of the electric damper increases, allowing the corresponding air outlet 300 to output more cold air, improving the cooling effect on the area. This allows different areas to adaptively adjust the output of cold air and the discharge of hot air according to the temperature, achieving a zoned temperature control effect.

[0051] When the reserved equipment is installed in the compartment, the drive motor 5 drives the connecting shaft 4 to rotate. The connecting shaft 4 drives the rotating shafts 33 at both ends to rotate, causing the spur gears 32 on the two rotating shafts 33 to drive the rack 31 to move. This causes the sliding top cover 21 to slide outward. At the same time, the connecting shaft 4 drives the rotating shafts 33 at both ends to rotate, and the driving bevel gear 34 on the rotating shaft 33 drives the driven bevel gear 35 on the transmission shaft 36 to rotate, causing the transmission shaft 36 to rotate. The other end of the transmission shaft 36 drives the rotating shaft 33 of the other sliding top cover 21 to rotate, causing the other sliding top cover 21 to slide outward as well. The two sliding top covers 21 slide in opposite directions synchronously, thereby opening the top opening of the compartment 1. In this way, the equipment can be directly hoisted into the compartment 1 from the top opening by a crane for installation, making it more convenient to use.
