Description

Technical Field

[0001] The present application belongs to the field of power transformation and distribution equipment, and specifically relates to a multi-layer prefabricated cabin and a substation. Background Art

[0002] Prefabricated substations are factory-produced, with the majority of assembly and commissioning work completed in-house, reducing on-site construction time. Compared to traditional substations, construction cycles can be shortened by 50% or more. Furthermore, with increasingly scarce land resources, multi-story substations with two or more floors are rapidly gaining popularity, significantly reducing their footprint. Furthermore, their compact structure and rational layout facilitate road transport and adapt to diverse terrains and environments, such as narrow streets, mountainous areas, or densely built-up areas.

[0003] The middle deck of a three-dimensional substation features a stair access. Access stairs can be installed or temporarily constructed in the compartments below the deck. Operations and maintenance personnel can ascend to the compartments above the deck via the access stairs. However, the presence of the access stairs can significantly reduce the level of protection between the compartments of the three-dimensional substation if a fire or other emergency occurs in one of the compartments above or below the deck.

[0045] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0046] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0047] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0048] See also Figures 1 to 3 As shown, in this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, an intermediate layer 200, and a protective isolation device 500. The cabin body 100 includes a bottom plate 110 and a top plate 120 spaced apart, and side walls 130 disposed between the bottom plate 110 and the top plate 120. The side walls 130 surround the edges of the bottom plate 110 and the top plate 120. The bottom plate 110, the top plate 120, and the side walls 130 can be connected by welding or fasteners. The side walls 130 are cylindrical structures with a rectangular cross-section. The bottom plate 110, the top plate 120, and the side walls 130 enclose a space for installing power substation equipment.

[0049] The cabin 100 comprises n layers of cabins arranged vertically from bottom to top, with adjacent cabins separated by intermediate panels 200, where n is an integer greater than or equal to 2. For example, if n is 2, one intermediate panel 200 divides the cabin 100 into two layers of cabins; if n is 3, two intermediate panels 200 are spaced apart along the height, and the two intermediate panels 200 divide the cabin 100 into three layers of cabins. For ease of understanding, this embodiment illustrates the cabin 100 as divided into two layers of cabins. The principles of dividing the cabin 100 into three or more layers of cabins are the same, and therefore will not be further described. The intermediate panels 200 are provided with access holes 210.

[0050] The protective isolation device 500 is disposed at the passage hole 210 and is used to open or close the passage hole 210. The protective isolation device 500 is disposed at the passage hole 210, that is, the protective isolation device 500 can be disposed on the upper side, the lower side or in the passage hole 210 of the intermediate layer 200.

[0051] The protective isolation device 500 includes a closed state and an open state. In the open state, a boarding ladder 300 can be set up in the lower cabin or a temporary boarding ladder 300 can be built. The operation and maintenance personnel can enter the upper cabin through the boarding ladder 300 and the passage hole 210, and the operation and maintenance personnel in the upper cabin can also enter the lower cabin through the passage hole 210; in the closed state, the passage hole 210 is closed by the protective isolation device 500, and the upper cabin and the lower cabin are physically isolated.

[0052] It should be noted that each intermediate panel 200 can be entirely disposed within the cabin 100, but is not limited thereto. The intermediate panel 200 can also extend into the sidewall 130 of the cabin 100, or penetrate the sidewall 130 of the cabin 100 and extend outside the cabin 100, depending on the specific circumstances. In other words, the sidewall 130 can be vertically segmented, with a section of the sidewall 130 being disposed between the bottom plate 110 and the intermediate panel 200, and a section of the sidewall 130 being disposed between the intermediate panel 200 and the top plate 120.

[0053] Existing three-dimensional substations have access hatches on the middle deck. Cabin access stairs can be installed or temporarily constructed in the compartments below the middle deck, allowing maintenance personnel to ascend to the compartments above the middle deck via the hatches. However, the presence of these hatches can significantly reduce the level of protection between compartments in a three-dimensional substation if a fire or other emergency occurs in one of the compartments above or below the middle deck.

[0054] In this embodiment, the cabin 100 includes n layers of cabins arranged vertically from bottom to top. Adjacent cabins are separated by an intermediate panel 200, where n is an integer greater than or equal to 2. The intermediate panel 200 is provided with an access hole 210. A protective isolation device 500 is disposed at the access hole 210 and is configured to open or close the access hole 210. The protective isolation device 500 has a closed state and an open state. In the open state, operation and maintenance personnel can enter the upper cabin via the cabin ladder 300 and the access hole 210. In the closed state, the access hole 210 is sealed by the protective isolation device 500, physically isolating the upper and lower cabins. This physical isolation prevents an emergency, such as a fire, in one cabin from affecting the adjacent cabin, thereby improving the level of protection between the cabins.

[0055] See also Figures 1 to 3 As shown, the protective isolation device 500 includes an isolation assembly 510, which includes a protective baffle 511. The protective baffle 511 is movably connected to the cabin 100. The protective baffle 511 can be made of high-temperature resistant fireproof material. In the closed state, the protective baffle 511 is located within the passage hole 210 or on the upper side of the intermediate layer 200, thereby closing the passage hole 210. The orthographic projection of the passage hole 210 on the protective baffle 511 coincides with the protective baffle 511 or is located within the protective baffle 511. The protective baffle 511 is located within the passage hole 210, and the upper surface of the protective baffle 511 can be flush with the upper surface of the intermediate layer 200; the protective baffle 511 is located on the upper side of the intermediate layer 200, that is, the protective baffle 511 is slightly higher than the intermediate layer 200. In the open state, the protective baffle 511 is away from the passage hole 210, thereby opening the passage hole 210.

[0056] The protective partition 511 is used to open or close the passage hole 210, so that the upper cabin and the lower cabin are physically isolated, thereby improving the protection level between the cabins.

[0057] See also Figures 1 to 3 As shown, the protective baffle 511 is hingedly connected to the cabin 100 or the intermediate panel 200. For example, the isolation assembly 510 includes a first pivot 512, and a first end of the protective baffle 511 is hingedly connected to the side wall 130 of the cabin 100 or the intermediate panel 200 via the first pivot 512. In the open state, the protective baffle 511 is substantially perpendicular to the intermediate panel 200. The protective baffle 511 can be rotated around the first pivot 512 until it is substantially parallel to the intermediate panel 200, i.e., it can be switched from the open state to the closed state.

[0058] The protective partition 511 is hingedly connected to the cabin 100 or the middle layer plate 200. In the event of an emergency such as a fire, the protective partition 511 can quickly close the passage hole 210 under the action of its own gravity, thereby physically isolating the upper cabin from the lower cabin.

[0059] It should be noted that the protective baffle 511 may be hingedly connected to the cabin 100 or the intermediate layer 200, but is not limited thereto. The protective baffle 511 may also be slidably connected to the intermediate layer 200. For example, the protective baffle 511 may be slidably disposed on the intermediate layer 200. In the open state, the protective baffle 511 is located at the mouth of the passage hole 210. In the closed state, the protective baffle 511 slides to the side of the passage hole 210.

[0060] In some embodiments, the protective isolation device 500 further includes a guardrail 520, which is disposed on the upper side of the intermediate layer plate 200 and located on at least one side of the passage hole 210. For example, the passage hole 210 includes a first side and a second side opposite to each other in the length direction, and a third side and a fourth side opposite to each other in the width direction. The boarding ladder 300 connects the first side of the passage hole 210 and the bottom plate 110 of the cabin 100. The guardrail 520 can surround the passage hole 210 and be disposed on the second side, the third side, and the fourth side of the passage hole 210. When the passage hole 210 is disposed close to the side wall 130 of the cabin 100, for example, the fourth side of the passage hole 210 is the side wall 130, the guardrail 520 can surround the passage hole 210 and be disposed on the second side and the third side of the passage hole 210, as shown in FIG. Figure 2 The protective partition 511 is connected to the middle layer plate 200 through the guardrail 520.

[0061] The guardrail 520 is arranged around the channel hole 210 to prevent operation and maintenance personnel or equipment from falling from the channel hole 210, thereby reducing safety risks.

[0062] In some embodiments, the protective baffle 511 has opposing first and second ends. The first end of the protective baffle 511 is hingedly connected to the end of the guardrail 520 near the intermediate layer 200 via a first pivot 512. In the open state, the protective baffle 511 is located on the side of the guardrail 520 near the access hole 210, and the second end of the protective baffle 511 is detachably connected to the guardrail 520. For example, a latch lock 530 is provided on the guardrail 520, and the second end of the protective baffle 511 is detachably connected to the guardrail 520 via the latch lock 530. When the latch lock 530 extends, the protective baffle 511 is fixed to the side of the guardrail 520 near the access hole 210. When the latch lock 530 retracts, the protective baffle 511 can rotate about the first pivot 512 to the mouth of the access hole 210, forming a closed state.

[0063] The first end of the protective partition 511 is hinged to the guardrail 520, and the second end of the protective partition 511 is detachably connected to the guardrail 520 through a latch lock 530. In the event of an emergency such as a fire, the latch of the latch lock 530 retracts, and the protective partition 511 can quickly close the passage hole 210 under the action of its own gravity, thereby physically isolating the upper cabin from the lower cabin.

[0064] See also Figures 4 to 7As shown, the multi-layer prefabricated cabin 10 also includes a cabin ladder 300, which is installed in cabins other than the nth cabin of the cabin body 100. The cabin ladder 300 has a stowed state and an deployed state. The sidewall 130 of the cabin body 100 is provided with a receiving groove 131. In the stowed state, the cabin ladder 300 is located in the receiving groove 131. The thickness of the cabin ladder 300 is less than or equal to the depth of the receiving groove 131. In the deployed state, the cabin ladder 300 is at least partially located outside the receiving groove 131. The cabin ladder 300 connects the access hole 210 to the bottom plate 110 or the intermediate layer plate 200 of the cabin body 100 below the access hole 210.

[0065] The cabin ladder 300 can be folded and stored in the accommodating groove 131 as a whole, without occupying the installation space and maintenance space of the power transformation equipment in the lower cabin.

[0066] It should be noted that the boarding ladder 300 connects the access hole 210 and the floor 110 of the cabin 100 below the access hole 210. This means that maintenance personnel on the floor 110 of the cabin 100 can ascend to the second-level cabin via the boarding ladder 300. The boarding ladder 300 does not need to contact the floor 110 of the cabin 100 or the intermediate layer 200. Furthermore, the multi-layer prefabricated cabin 10 may be provided with a boarding ladder 300, but this is not limited to this. The multi-layer prefabricated cabin 10 may also be provided without a boarding ladder 300, depending on the specific circumstances. If the multi-layer prefabricated cabin 10 is not provided with a boarding ladder 300, a temporary boarding ladder 300 can be constructed when boarding is required and then removed after use.

[0067] In some embodiments, the boarding ladder 300 includes a first bracket assembly 310, a second bracket assembly 320, and a plurality of steps 330 disposed between the first and second bracket assemblies 310, 320. The steps 330 are hingedly connected at both ends to the first and second bracket assemblies 310, 320, respectively. The first bracket assembly 310 is connected to the bottom surface of the receiving slot 131. The second bracket assembly 320 can rotate about the hinge axis between the steps 330 and the first bracket assembly 310, allowing the boarding ladder 300 to be folded or unfolded.

[0068] The two ends of the pedal 330 are hingedly connected to the first bracket assembly 310 and the second bracket assembly 320 respectively. The second bracket assembly 320 rotates around the hinge axis of the pedal 330 and the first bracket assembly 310 to realize the folding and storage or unfolding of the boarding ladder 300. This design can make the thickness of the boarding ladder 300 in the stored state small enough so that it can be folded and stored as a whole into the accommodating groove 131.

[0069] See also Figures 4 to 7As shown, in the deployed state, the pedal board 330 is parallel to the horizontal direction. The pedal board 330 comprises a rectangular frame and a plurality of grille bars arranged crisscrossly within the rectangular frame. In the deployed state, the pedal board 330 is parallel to the horizontal direction, that is, the upper and lower end surfaces of the rectangular frame of the pedal board 330 are parallel to the horizontal direction.

[0070] In the unfolded state, the pedal 330 is parallel to the horizontal direction, making it convenient for operation and maintenance personnel to board the cabin via the cabin ladder 300.

[0071] In some embodiments, the horizontal direction includes a length direction and a width direction that are perpendicular to each other (the length direction is Figure 1 In the left and right directions, the width direction is Figure 1 The first bracket assembly 310 and the second bracket assembly 320 are spaced apart along the width direction. Each of the first bracket assembly 310 and the second bracket assembly 320 includes a tilt link 311, a horizontal link 312, and a vertical link 313. The horizontal link 312 extends along the length direction, and multiple horizontal links 312 are spaced apart along the length direction and the height direction.

[0072] The first ends of all horizontal links 312 are connected to the tilt links 311. In the first bracket assembly 310, the horizontal links 312 are located above the tilt links 311, and in the second bracket assembly 320, the horizontal links 312 are located below the tilt links 311. Vertical links 313 extend in the vertical direction, connecting the second ends of the horizontal links 312 to the tilt links 311 and supporting the horizontal links 312. The pedals 330 are connected to the horizontal links 312 of the first bracket assembly 310 and the horizontal links 312 of the second bracket assembly 320. The tilt links 311 of the first bracket assembly 310 are connected to the bottom surface of the receiving slot 131.

[0073] The horizontal connecting rod 312 is used to connect the pedal 330 so that the pedal 330 is parallel to the horizontal direction. The vertical connecting rod 313 supports the horizontal connecting rod 312, thereby improving the structural strength of the boarding ladder 300.

[0074] In some embodiments, the boarding ladder 300 further includes a telescopic rod 340, a first end of the telescopic rod 340 being hingedly connected to the tilt link 311 of the first bracket assembly 310, and a second end of the telescopic rod 340 being hingedly connected to the pedal 330. Figure 3 The telescopic rod 340 includes a pneumatic telescopic rod, a hydraulic telescopic rod or an electric telescopic rod.

[0075] The first bracket assembly 310 and the step 330 are connected by a telescopic rod 340. The telescopic rod 340 can assist in folding and storing the boarding ladder 300. In addition, the telescopic rod 340 can also act as a limiter to prevent the boarding ladder 300 from folding during use and unfolding when not in use.

[0076] See also Figure 8 As shown, the multi-layer prefabricated cabin 10 further includes a linkage isolation device 400, which is used to open or close the access hole 210. The linkage isolation device 400 includes a linkage partition 410 and a slide rail 420. The slide rail 420 is disposed on the side of the intermediate layer 200 near the bottom plate 110 of the cabin body 100. The linkage partition 410 is slidably mounted on the slide rail 420. The linkage partition 410 can be made of a high-temperature resistant and fireproof material.

[0077] When the boarding ladder 300 is stored in the accommodating groove 131, the linkage partition 410 can be slid out to close the passage hole 210, thereby isolating the two cabins connected by the passage hole 210, delaying or blocking the spread of dangerous situations such as fire in one cabin to another cabin.

[0078] In some embodiments, the linkage partition 410 is movably connected to the second bracket assembly 320. The second bracket assembly 320 can drive the linkage partition 410 to slide within the slide rail 420, allowing the linkage partition 410 to open or close the channel hole 210. For example, a slide groove extending along the length of the linkage partition 410 is provided on the side of the linkage partition 410 near the second bracket assembly 320, and a slide groove extending along the direction of the linkage partition 210 is provided on the side of the tilt link 311 of the second bracket assembly 320 near the linkage partition 410. Slide blocks are provided in the two slide grooves to connect the tilt link 311 and the linkage partition 410. When the second bracket assembly 320 rotates, the slide blocks slide in the two slide grooves, driving the linkage partition 410 to slide on its slide rail 420.

[0079] It should be noted that the linkage partition 410 and the second bracket assembly 320 are movably connected, that is, the linkage partition 410 and the second bracket assembly 320 are mechanically linked, but this is not limited to this. The linkage partition 410 and the second bracket assembly 320 can also be linked by a controller, depending on the specific situation. For example, the linkage isolation device 400 also includes a driver, which drives the linkage partition 410 to slide, and the telescopic rod 340 to drive the pedal 330 to rotate, and the driver and the telescopic rod 340 are both connected to the controller. When boarding is required, the controller controls the linkage partition 410 via the driver to open the access hole 210, and simultaneously controls the pedal 330 to rotate via the telescopic rod 340, thereby deploying the boarding ladder 300. When not in use, the controller controls the pedal 330 to rotate via the telescopic rod 340, thereby folding and storing the boarding ladder 300, and simultaneously controls the linkage partition 410 via the driver to close the access hole 210.

[0080] The second bracket assembly 320 drives the linkage partition 410 to slide, achieving linkage between the boarding ladder 300 and the linkage partition 410. When the boarding ladder 300 is folded, the access hole 210 is automatically closed, thereby enhancing the protection level of the multi-story prefabricated cabin 10. When the boarding ladder 300 is deployed, the upper end of the boarding ladder 300 extends into the access hole 210, and the linkage partition 410 cannot close the access hole 210. In the event of an emergency such as a fire, the access hole 210 can be closed by the isolation assembly 510, achieving physical isolation between the upper and lower cabins.

[0081] See also Figure 2 and Figure 3 As shown, in the closed state, the receiving groove 131 and the protective baffle 511 are located on opposite sides of the passage hole 210. The protective isolation device 500 also includes a limit assembly 540, which is disposed on the side wall 130 of the cabin 100 and can lock the second end of the protective baffle 511 in the open state.

[0082] When an emergency such as a fire occurs, the protective baffle 511 isolates the upper compartment from the lower compartment, and the limiting assembly 540 locks the second end of the protective baffle 511 to prevent the airflow from lifting the protective baffle 511.

[0083] In some embodiments, the limiting assembly 540 includes a limiting baffle 541 and a second pivot 542. A clearance groove 132 is provided on the side of the receiving slot 131 away from the bottom plate 110 of the cabin 100. In the open state, the limiting baffle 541 is located within the clearance groove 132. The limiting baffle 541 has a first end and a second end that oppose each other. The first end of the limiting baffle 541 is hingedly connected to the lower side of the clearance groove 132 via the second pivot 542, and the second end of the limiting baffle 541 is detachably connected to the side wall 130 of the cabin 100. For example, a latch lock 530 is provided on the side wall 130 of the cabin 100, and the second end of the limiting baffle 541 is detachably connected to the side wall 130 of the cabin 100 via the latch lock 530. The latch of the latch lock 530 extends and retracts, and the limiting baffle 541 can rotate about the second pivot 542, so that the second end of the limiting baffle 541 contacts the protective baffle 511 to form a closed state. In the closed state, the limiting baffle 541 at least partially overlaps the accommodating groove 131.

[0084] When the linkage partition 410 contacts the sidewall 130 of the cabin 100, the boarding ladder 300 cannot completely fill the accommodating groove 131, and the upper and lower cabins are connected through the gap in the accommodating groove 131. The limiting baffle 541 at least partially overlaps the accommodating groove 131, which not only serves as a limit but also blocks the gap in the accommodating groove 131, thereby improving the protection level between the cabins.

[0085] See also Figures 9 to 12The first cabin layer of the cabin body 100 from bottom to top is provided with a boarding door 141 for personnel to enter and exit. The boarding door 141 is used for emergency escape from the first cabin layer and daily entry and exit of the first cabin layer of the cabin body 100. The number of the boarding doors 141 can be set according to demand. For example, two boarding doors 141 are set in the length direction of the cabin body 100 ( Figure 9 and Figure 10 on both sides of the middle and upper and lower directions).

[0086] The middle layer board 200 is provided with a first cable channel 220, which is used for routing cables between layers. Figure 9 and Figure 10 A first cable channel 220 is provided on each side (in the left-right direction). The substation equipment in the upper and lower compartments on one side of the cabin 100 is connected via the first first cable channel 220, while the substation equipment in the upper and lower compartments on the other side of the cabin 100 is connected via the second first cable channel 220. Second cable channels 111 may be provided on the bottom plate 110 of the cabin 100. These second cable channels 111 are used to route external cables into the cabin 100. The number and position of second cable channels 111 may correspond to those of the first cable channels 220, with one second cable channel 111 provided below each first cable channel 220.

[0087] Cable channels are provided on the middle layer plate 200 and the bottom plate 110 to facilitate the entry of external cables into the cabin 100 and the electrical connection of power conversion equipment between the upper and lower cabins of the cabin 100.

[0088] In some embodiments, the multi-layer prefabricated cabin 10 is divided into a plurality of cabin sections along the length direction or the width direction, and adjacent cabin sections are connected by welding or fasteners. For example, the multi-layer prefabricated cabin 10 is divided into two cabin sections along the width direction, namely Figure 9 The first compartment 11 on the left and Figure 9 The second cabin section 12 on the right side is welded to the first cabin section 11 and the second cabin section 12. It should be understood that the multi-layer prefabricated cabin 10 can be divided into multiple cabin sections along the length or width direction according to its length or width dimension, and can also be divided into multiple cabin sections along the height direction according to its height dimension.

[0089] The multi-layer prefabricated cabin 10 is divided into multiple cabin sections along the length direction, which can realize modular division. On the one hand, it can be prefabricated in the factory to shorten the construction period of the substation. On the other hand, it can reduce the difficulty and cost of road transportation.

[0090] The present application also provides a substation, which includes a multi-layer prefabricated cabin 10 and a power transformation device, and the power transformation device is arranged in the multi-layer prefabricated cabin 10.

[0091] For example, a first cable duct 220 and a second cable duct 111 are provided in the middle of the length of the first compartment 11, with transformer equipment 20 provided on both sides of the length of the second cable duct 111, and switchgear 30 provided on both sides of the length of the first cable duct 220. A wall 600 can be installed in the area where the transformer equipment 20 and the second cable duct 111 of the first compartment 11 are located to isolate the transformer equipment 20 and the second cable duct 111. An access door 142 can be provided on the wall 600 of the first compartment 11 or on the sidewall 130 of the transformer equipment 20 of the first compartment 11 to provide access to the area enclosed by the wall 600. Accordingly, a wall 600 and an access door 142 can also be provided in the area where the first cable duct 220 and the switchgear 30 are located.

[0092] The second compartment 12 is equipped with a first cable channel 220 and a second cable channel 111. Power distribution equipment 40 is located on one longitudinal side (e.g., the upper side) of the second cable channel 111, and switchgear 30 is located on the other longitudinal side (e.g., the lower side) of the second cable channel 111. Power transformation equipment includes transformer equipment 20, switchgear 30, and power distribution equipment 40. The channel hole 210 can be located on the side of the first cable channel 220 away from the first compartment 11. Power transformation equipment can be located on both longitudinal sides of the first cable channel 220, depending on the application.

[0093] The first-floor cabin of the second compartment 12 is also equipped with an outdoor air conditioner 51. This outdoor air conditioner 51 can be installed on the floor 110 and located on the side of the power distribution equipment 40 away from the first compartment 11. Ventilation holes can be provided on the sidewall 130 facing the outdoor air conditioner 51 to exhaust air from the outdoor air conditioner 51. The first-floor cabin of the second compartment 12 is also equipped with an indoor air conditioner 52. This indoor air conditioner 52 can be installed on one or both of the longitudinal sidewalls 130 and located near the intermediate deck 200. The second floor of the second compartment 12 is also equipped with an indoor air conditioner 52. A boarding door 141 can be installed on the sidewall 130 of the first-floor cabin of the second compartment 12. Furthermore, an emergency escape module 700 can be installed on the sidewall 130 of the second-floor cabin of the second compartment 12. This emergency escape module 700 can be located on the sidewall 130 facing the first compartment 11. When an emergency such as a fire occurs in the first-floor cabin, the operation and maintenance personnel do not have to go down to the first-floor cabin, and can directly escape from the cabin body 100 from the second-floor cabin through the emergency escape module 700.

[0094] It should be understood that the positions of the boarding door 141, the inspection door 142, the transformer equipment 20, the switch equipment 30, the power distribution equipment 40, the air-conditioning outdoor unit 51, the air-conditioning indoor unit 52 and the emergency escape module 700 are not limited to the above examples, and their specific positions can be adjusted as needed.

[0095] In this embodiment, the cabin 100 includes n layers of cabins arranged vertically from bottom to top. Adjacent cabins are separated by an intermediate panel 200, where n is an integer greater than or equal to 2. The intermediate panel 200 is provided with an access hole 210. A protective isolation device 500 is disposed at the access hole 210 and is configured to open or close the access hole 210. The protective isolation device 500 has a closed state and an open state. In the open state, operation and maintenance personnel can enter the upper cabin via the cabin ladder 300 and the access hole 210. In the closed state, the access hole 210 is sealed by the protective isolation device 500, physically isolating the upper and lower cabins. This physical isolation prevents an emergency, such as a fire, in one cabin from affecting the adjacent cabin, thereby improving the level of protection between the cabins.
