[0040] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments 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 intended to explain the present application, and should not be construed as limiting the present application.

[0041] See Figures 1 to 3As shown, in this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, an intermediate layer 200, and an emergency escape module 300. The cabin body 100 includes a bottom plate 110 and a top plate 120 spaced apart, and a side wall 130 disposed between the bottom plate 110 and the top plate 120, the side wall 130 surrounding the edges of the bottom plate 110 and the top plate 120. The bottom plate 110, the top plate 120, and the side wall 130 can be welded together or connected by fasteners. The side wall 130 is a cylindrical structure with a rectangular cross-section, and the bottom plate 110, the top plate 120, and the side wall 130 enclose a space for installing electrical equipment.

[0042] n-1 intermediate shelves 200 are arranged within the cabin 100, dividing the cabin 100 into n layers, where n is an integer greater than or equal to 2. For example, if n equals 2, one intermediate shelf 200 divides the cabin 100 into two layers; if n equals 3, two intermediate shelves 200 are arranged vertically at intervals, dividing the cabin 100 into three layers. For ease of understanding, this embodiment uses the cabin 100 divided into two layers for illustration. When the cabin 100 is divided into three or more layers, the principle is the same as when the cabin 100 is divided into two layers, so it will not be described again.

[0043] An emergency escape module 300 is installed on at least one of the (n-1)th side walls 130 of the cabin 100 from top to bottom. For example, if the cabin 100 has two layers, the emergency escape module 300 can be installed on the side wall 130 of the first layer from top to bottom; if the cabin 100 has three layers, the emergency escape module 300 can be installed on the side walls 130 of the first and / or second layers from top to bottom. The emergency escape module 300 includes a retractable or foldable escape ladder 320, an escape rope ladder, an escape rope, and a descent device, etc., and is used for personnel to escape from the cabin 100.

[0044] It should be noted that each intermediate shelf 200 can be integrally installed within the cabin 100, but is not limited to this. The intermediate shelf 200 can also extend into or through the side wall 130 of the cabin 100, extending outside the cabin 100, depending on the specific circumstances. That is to say, the side wall 130 can be vertically segmented. A section of side wall 130 can be provided between the bottom plate 110 and the intermediate shelf 200, and a section of side wall 130 can be provided between the intermediate shelf 200 and the top plate 120.

[0045] In existing multi-level substations, the upper and lower levels are connected by stairs and inter-level cable channels. When a fire occurs on the lower level, the upper level will be directly affected, and the maintenance personnel on the upper level will have difficulty escaping, posing a significant safety hazard.

[0046] In this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, intermediate floor slabs 200, and an emergency escape module 300. The cabin body 100 includes a floor slab 110 and a top slab 120 spaced apart, and a side wall 130 disposed between the floor slab 110 and the top slab 120. The side wall 130 surrounds the edges of the floor slab 110 and the top slab 120. n-1 intermediate floor slabs 200 are disposed within the cabin body 100, dividing the cabin body 100 into n layers, where n is an integer greater than or equal to 2. The emergency escape module 300 is disposed on at least one of the side walls 130 of the n-1 layers of the cabin body 100 from top to bottom. In the event of an emergency such as a fire within the cabin body 100, maintenance personnel can escape directly from the upper layers through the emergency escape module 300 without having to descend to the first layer of the cabin body 100, thus solving the problem of difficult escape from the upper layers of the multi-layer prefabricated cabin 10 and reducing the safety risks for maintenance personnel.

[0047] See Figures 1 to 3 As shown, the emergency escape module 300 includes an escape and maintenance platform 310, an escape ladder 320, and a first pivot 331. The bottom end of the escape and maintenance platform 310 is hinged to the side wall 130 or the intermediate shelf 200 of the cabin 100 via the first pivot 331. An escape doorway 131 is provided on the side wall 130. The escape and maintenance platform 310 can be flipped into the escape doorway 131 or the cabin 100 to form a folded state, and the escape and maintenance platform 310 can also be flipped out of the cabin 100 to form an unfolded state.

[0048] An escape hatch 311 is provided on the escape and maintenance platform 310, and an escape ladder 320 is connected to the escape and maintenance platform 310. The escape doorway 131 is a rectangular opening, and the escape and maintenance platform 310 is also rectangular in shape, with its height being less than or equal to the height of the escape doorway 131. The escape hatch 311 is also a rectangular opening and is located in the central area of ​​the escape and maintenance platform 310. In the deployed state, the escape ladder 320 is located below the escape and maintenance platform 310.

[0049] In normal use, the escape and maintenance platform 310 and escape ladder 320 of the multi-story prefabricated cabin 10 are folded inside the cabin body 100. In case of emergency, maintenance personnel can unfold the escape and maintenance platform 310 and escape ladder 320 and escape through the escape doorway 131 and escape opening 311 to escape outside the cabin body 100. In addition, when the transformer equipment on the upper floor needs to be replaced, the transformer equipment can be hoisted onto the escape and maintenance platform 310 and then transported into the cabin body 100 through the escape doorway 131.

[0050] The escape maintenance platform 310 and escape ladder 320 are foldable, and the emergency escape module 300 has a small storage volume, which does not affect the installation of the power equipment inside the cabin 100 or the appearance of the cabin 100.

[0051] See Figures 2 to 5As shown, the escape ladder 320 includes multiple steps 321 and two telescopic links 322, with the two telescopic links 322 positioned at both ends of the multiple steps 321. A rectangular clearance slot 312 is provided on the outer side of the escape maintenance platform 310, with one side of the rectangular clearance slot 312 communicating with the escape opening 311. The emergency escape module 300 also includes a second pivot 332. The first end of the telescopic link 322 is hinged to the outer side of the escape maintenance platform 310 via the second pivot 332, which is located within the rectangular clearance slot 312. The second end of the telescopic link 322 is detachably connected to the escape maintenance platform 310. The axis of the second pivot 332 is approximately perpendicular to the side wall 130 of the adjacent compartment 100.

[0052] The first end of the telescopic link 322 is hinged to the escape and maintenance platform 310, and the second end of the telescopic link 322 is detachably connected to the escape and maintenance platform 310. In case of emergency, maintenance personnel can detach the second end of the telescopic link 322, rotate the escape ladder 320 to the bottom of the escape and maintenance platform 310, and extend the escape ladder 320 to the ground to escape the cabin 100 through the escape ladder 320.

[0053] In the folded state, the second end of the telescopic link 322 is detachably connected to the escape and maintenance platform 310, preventing the escape ladder 320 from accidentally opening and causing safety hazards. The axis of the second pivot 332 is approximately perpendicular to the side wall 130 of the adjacent cabin 100, which can prevent the escape ladder 320 from interfering with the cabin 100 and affecting the deployment angle of the escape ladder 320.

[0054] See Figures 2 to 5 As shown, the emergency escape module 300 also includes a limiting frame 340, which is mounted on the escape maintenance platform 310. The limiting frame 340 and the second pivot 332 are located on opposite sides of the escape opening 311. The limiting frame 340 can be positioned inside the escape opening 311. The second end of the telescopic link 322 is provided with an insertion hole 3221. In the folded state, the limiting frame 340 is located in the insertion hole 3221. Both the limiting frame 340 and the telescopic link 322 are provided with pin holes 341, and the limiting frame 340 and the telescopic link 322 are detachably connected through quick-release pins in the pin holes 341.

[0055] In case of an emergency, maintenance personnel can manually pull out the quick-release pin in the pin hole 341, slightly shorten the escape ladder 320, remove the limit bracket 340 from the insertion hole 3221 at the second end of the telescopic link 322, pull out the escape ladder 320 and rotate it downwards so that the second end of the escape ladder 320 contacts the ground. At this time, the emergency escape module 300 is in the deployed state, and maintenance personnel can escape the cabin 100 through the escape ladder 320.

[0056] Once the emergency has passed, the escape ladder 320 can be rotated upwards and shortened so that it is roughly parallel to the escape maintenance platform 310. Then, the escape ladder 320 can be slightly extended, and the limit frame 340 can be inserted into the insertion hole 3221 at the second end of the telescopic link 322. Then, the quick-release pin can be inserted to lock the limit frame 340 and the telescopic link 322. At this time, the emergency escape module 300 is in a folded state.

[0057] The second end of the telescopic link 322 is detachably connected to the limit frame 340 on the escape maintenance platform 310 via a quick-release pin. The connection structure is simple, highly reliable, and less prone to failure that could prevent the escape ladder 320 from unfolding.

[0058] See Figure 3 and Figure 4 As shown, the emergency escape module 300 also includes an escape manhole cover 350. One end of the escape manhole cover 350 is hinged to the escape opening 311 via a third pivot 333, and the other end of the escape manhole cover 350 is connected to the escape opening 311 via a bolt lock 334.

[0059] In case of emergency, maintenance personnel can open the latch lock 334 and flip the escape manhole cover 350 inward to open the escape hatch 311, and then unfold the escape ladder 320 to escape. During normal use, the escape manhole cover 350 closes the escape hatch 311 to prevent maintenance personnel or items from falling out of the escape hatch 311.

[0060] See Figure 3 As shown, the emergency escape module 300 also includes a folding lever 360. The first end of the folding lever 360 is hinged to the escape and maintenance platform 310, and the second end is hinged to the side wall 130 of the cabin 100. Both the connection between the folding lever 360 and the escape and maintenance platform 310, and the connection between the folding lever 360 and the side wall 130 of the cabin 100, are spaced apart from the third pivot 333.

[0061] The folding lever 360 includes two hinged connecting rods, and can be folded or unfolded. In the unfolded state, the angle between the two connecting rods is approximately 180 degrees, and the folding lever 360 is a straight rod that holds the escape and maintenance platform 310 and the side wall 130 of the cabin 100 together with the third pivot 333 to limit the angle between the escape and maintenance platform 310 and the intermediate shelf 200 to less than 180 degrees. In the folded state, the angle between the two connecting rods is close to 0 degrees, and the escape and maintenance platform 310 is approximately parallel to the side wall 130 of the cabin 100 on the same side.

[0062] When the escape and maintenance platform 310 is deployed, the folding lever 360 acts as a damping deceleration mechanism to reduce the impact force. In the deployed state, the folding lever 360 holds the escape and maintenance platform 310 and the side wall 130 of the cabin 100, thereby improving the structural strength of the escape and maintenance platform 310.

[0063] When it is necessary to replace the upper-level power equipment, a slide rail can be installed on the escape and maintenance platform 310, and then the power equipment can be hoisted onto the slide rail. Since the angle between the escape and maintenance platform 310 and the intermediate shelf 200 is less than 180 degrees, the power equipment can be easily transported into the cabin 100 via the slide rail.

[0064] In some embodiments, the emergency escape module 300 further includes a telescopic rod 370, which connects the escape manhole cover 350 and the escape maintenance platform 310. The connection ends of the telescopic rod 370 with the escape manhole cover 350 and the escape maintenance platform 310 are both located away from the third pivot 333. The telescopic rod 370 may be a pneumatic telescopic rod, a hydraulic telescopic rod, or an electric telescopic rod.

[0065] A telescopic rod 370 is installed between the escape manhole cover 350 and the escape maintenance platform 310. This can reduce the resistance to opening the escape manhole cover 350 and limit the rotation of the escape manhole cover 350, so as to prevent the escape manhole cover 350 from closing accidentally during the use of the emergency escape module 300 and injuring the maintenance personnel who are escaping through the emergency escape module 300.

[0066] In some embodiments, the emergency escape module 300 further includes a bolt lock 334 and a positioning baffle 335, the positioning baffle 335 being disposed inside the escape doorway 131. In the folded state, the escape maintenance platform 310 contacts the positioning baffle 335, which limits the inward tilting angle of the escape maintenance platform 310. Simultaneously, in the folded state, the escape maintenance platform 310 is connected to the escape doorway 131 via another bolt lock 334.

[0067] In the folded state, the escape and maintenance platform 310 contacts the positioning baffle 335. The positioning baffle 335 limits the angle at which the escape and maintenance platform 310 flips inward. The latch lock 334 locks the escape and maintenance platform 310 to prevent it from unfolding in a non-emergency situation.

[0068] See Figure 3 and Figure 6 As shown, the emergency escape module 300 also includes a guardrail 380, one end of which is provided with a waist eye hole 381. A positioning hole 313 is provided on the escape maintenance platform 310, and the positioning hole 313 and the first pivot 331 are located on opposite sides of the escape opening 311. A rotating shaft 336 is provided on the inner side of the escape maintenance platform 310, parallel to and above the escape maintenance platform 310, and passes through the waist eye hole 381.

[0069] In the unfolded state, the guardrail 380 is approximately perpendicular to the escape and maintenance platform 310, with the guardrail 380 inserted into the positioning hole 313, and the rotating shaft 336 contacting the first end of the eyelet hole 381. In the folded state, the guardrail 380 is approximately parallel to the escape and maintenance platform 310, with the guardrail 380 located inside the escape and maintenance platform 310, and the rotating shaft 336 contacting the second end of the eyelet hole 381. In case of emergency, maintenance personnel can flip the guardrail 380 so that it is approximately perpendicular to the escape and maintenance platform 310, then insert the guardrail 380 into the positioning hole 313, and then open the escape manhole cover 350. After the emergency is over, the guardrail 380 can be lifted and flipped inward so that it is approximately parallel to the escape and maintenance platform 310.

[0070] When using the emergency escape module 300, the guardrail 380 is flipped up and erected, blocking the outside of the escape and maintenance platform 310, which can prevent maintenance personnel or power equipment from falling from the escape and maintenance platform 310 and reduce safety risks.

[0071] In some embodiments, the multi-layer prefabricated cabin 10 further includes an escape door 390 and a door closer 337. The escape door 390 is used to open or close the escape doorway 131. One side of the escape door 390 is hinged to the escape doorway 131, and the other side of the escape door 390 is connected to the escape doorway 131 via a door lock 338. When the escape ladder 320 is thick, a storage slot can be provided on the escape door 390 to store the escape ladder 320. The door lock 338 includes a lock body and a lock hook. The lock body can be provided on the escape door 390, and the lock hook can be provided on the side wall 130 of the cabin 100.

[0072] The height of the escape maintenance platform 310 is less than the height of the door lock 338 to prevent the escape maintenance platform 310 from obstructing the door lock 338. Furthermore, since the height of the escape maintenance platform 310 is less than the height of the door lock 338 (i.e., the height of the escape maintenance platform 310 is less than the height of the escape door opening 131), the bolt lock 334 of the escape maintenance platform 310 can be located on the outside of the escape maintenance platform 310, so that when the escape door 390 is closed, the bolt lock 334 of the escape maintenance platform 310 cannot be opened. The door closer 337 connects the cabin 100 and the escape door 390, and the door closer 337 is used to limit the opening angle of the escape door 390 and to close the escape door 390.

[0073] In case of emergency, the escape door 390 can be opened, and the escape maintenance platform 310 can be deployed. The escape maintenance platform 310 holds the escape door 390 in place to prevent it from closing under the action of the door closer 337.
