[0039] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted here 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 by referring to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0040] See Figures 1 to 3 As shown, in this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, an intermediate layer plate 200, and an emergency escape module 300. The cabin body 100 includes a bottom plate 110 and a top plate 120 arranged at intervals, 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 using fasteners. The side walls 130 are cylindrical structures with a rectangular cross-section, and the bottom plate 110, the top plate 120, and the side walls 130 enclose a space for installing power transformation equipment.

[0041] The cabin body 100 includes n layers of cabins arranged in sequence from bottom to top. Adjacent two of the cabins are separated by the intermediate layer plate 200, and n is an integer greater than or equal to 2. For example, when n is equal to 2, 1 intermediate layer plate 200 separates the cabin body 100 into two layers of cabins; when n is equal to 3, 2 intermediate layer plates 200 are arranged at intervals in the vertical direction, and the 2 intermediate layer plates 200 separate the cabin body 100 into 3 layers of cabins. For the convenience of understanding, this embodiment will be described by taking the cabin body 100 being divided into two layers of cabins as an example. When the cabin body 100 is divided into 3 layers and more than 3 layers of cabins, the principle is the same as that when the cabin body 100 is divided into two layers of cabins, so it will not be elaborated further.

[0042] The emergency escape module 300 is disposed on the sidewall of at least one other compartment except the first - layer compartment of the compartment body 100. The emergency escape module 300 is used for maintenance personnel to escape from the compartment body 100. For example, when the compartment body 100 is divided into two layers, the emergency escape module 300 can be disposed on the sidewall 130 of the first - layer compartment from top to bottom; when the compartment body 100 is divided into three layers, the emergency escape module 300 can be disposed on the sidewall 130 of the first - layer compartment and / or the second - layer compartment from top to bottom. The emergency escape module 300 includes a retractable or foldable escape ladder 320, an escape soft ladder, an escape rope, a descent controller, etc. The emergency escape module 300 is used for personnel to escape from the compartment body 100.

[0043] It should be noted that each intermediate layer plate 200 can be integrally disposed inside the compartment body 100, but is not limited thereto. The intermediate layer plate 200 can also extend into the sidewall 130 of the compartment body 100 or penetrate through the sidewall 130 of the compartment body 100 and extend outside the compartment body 100, which can be determined according to specific circumstances. That is to say, the sidewall 130 can be vertically segmented. A section of the sidewall 130 can be disposed between the bottom plate 110 and the intermediate layer plate 200, and a section of the sidewall 130 can be disposed between the intermediate layer plate 200 and the top plate 120.

[0044] In the existing three - dimensional substation, the upper - layer compartment and the lower - layer compartment are connected through stairs, inter - layer cable channels, etc. When a fire occurs in the lower - layer compartment, the upper - layer compartment will be directly affected, and it is difficult for the maintenance personnel in the upper - layer compartment to escape from the upper - layer compartment, presenting a major safety hazard.

[0045] In this embodiment, the multi - layer prefabricated compartment 10 includes n layers of compartments arranged in sequence from bottom to top. Adjacent two compartments are separated by an intermediate layer plate 200, where n is an integer greater than or equal to 2. The emergency escape module 300 is disposed on the sidewall of at least one other compartment except the first - layer compartment of the compartment body 100. The emergency escape module 300 is used for maintenance personnel to escape from the compartment body 100. When an emergency such as a fire occurs inside the compartment body 100, the maintenance personnel can directly escape from the upper - layer compartment through the emergency escape module 300 without having to go down to the first - layer compartment of the compartment body 100, solving the problem of difficult escape from the upper - layer compartment of the multi - layer prefabricated compartment 10 and reducing the safety risk of the maintenance personnel.

[0046] 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 sidewall 130 or the intermediate layer plate 200 of the compartment body 100 through the first pivot 331. An escape door opening 131 is provided on the sidewall 130. The escape and maintenance platform 310 can be flipped to the escape door opening 131 or inside the compartment body 100 to form a folded state, and the escape and maintenance platform 310 can be flipped outside the compartment body 100 to form an unfolded state.

[0047] An escape and maintenance platform 310 is provided with an escape opening 311, and an escape ladder 320 is connected to the escape and maintenance platform 310. The escape door opening 131 is a rectangular hole, and the outer shape of the escape and maintenance platform 310 is also rectangular, and the height of the escape and maintenance platform 310 is less than or equal to the height of the escape door opening 131. The escape opening 311 is also a rectangular hole, and the escape opening 311 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.

[0048] During the normal use of the multi-layer prefabricated cabin 10, the escape and maintenance platform 310 and the escape ladder 320 are both folded into the cabin body 100; when an emergency occurs, the operation and maintenance personnel can deploy the escape and maintenance platform 310 and the escape ladder 320, and escape from the cabin body 100 through the escape door opening 131 and the escape opening 311. In addition, when the power transformation equipment in the upper cabin needs to be replaced, the power transformation equipment can also be hoisted onto the escape and maintenance platform 310 and then transported into the cabin body 100 through the escape door opening 131.

[0049] The escape and maintenance platform 310 and the escape ladder 320 can be folded, and the storage volume of the emergency escape module 300 is small, which does not affect the installation of the power transformation equipment in the cabin body 100 and the appearance of the cabin body 100.

[0050] See Figures 2 to 5 As shown, the escape ladder 320 includes a plurality of treads 321 and two telescopic connecting rods 322, and the two telescopic connecting rods 322 are arranged at both ends of the plurality of treads 321. A rectangular relief groove 312 is provided on the outer side of the escape and maintenance platform 310, and one side of the rectangular relief groove 312 is communicated with the escape opening 311. The emergency escape module 300 further includes a second pivot 332, and the first end of the telescopic connecting rod 322 is hinged to the outer side of the escape and maintenance platform 310 through the second pivot 332, and the second pivot 332 is located in the rectangular relief groove 312. The second end of the telescopic connecting rod 322 is detachably connected to the escape and maintenance platform 310. The axis of the second pivot 332 is substantially perpendicular to the side wall 130 of the adjacent cabin body 100.

[0051] The first end of the telescopic connecting rod 322 is hinged to the escape and maintenance platform 310, and the second end of the telescopic connecting rod 322 is detachably connected to the escape and maintenance platform 310. When an emergency occurs, the operation and maintenance personnel can detach the second end of the telescopic connecting rod 322, rotate the escape ladder 320 to below the escape and maintenance platform 310, and extend the escape ladder 320 to the ground to escape from the cabin body 100 through the escape ladder 320.

[0052] In the folded state, the second end of the telescopic link 322 is detachably connected to the escape and maintenance platform 310 to avoid potential safety hazards caused by accidental opening of the escape ladder 320. The axis of the second pivot 332 is substantially 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.

[0053] See Figures 2 to 5 As shown, the emergency escape module 300 further includes a limit frame 340, which is arranged on the escape and maintenance platform 310. The limit frame 340 and the second pivot 332 are located on opposite sides of the escape opening 311. The limit frame 340 can be arranged inside the escape opening 311. An insertion hole 3221 is provided at the second end of the telescopic link 322. In the folded state, the limit frame 340 is located in the insertion hole 3221. Pin holes 341 are provided on both the limit frame 340 and the telescopic link 322. The limit frame 340 and the telescopic link 322 are detachably connected by a quick-release pin in the pin hole 341.

[0054] When an emergency occurs, the maintenance personnel can manually pull out the quick-release pin in the pin hole 341, slightly shorten the escape ladder 320, withdraw the limit frame 340 from the insertion hole 3221 at the second end of the telescopic link 322, then pull out the escape ladder 320 and rotate the escape ladder 320 downward 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 the maintenance personnel can escape from the cabin 100 through the escape ladder 320.

[0055] When the emergency is eliminated, the escape ladder 320 can be rotated upward and shortened so that the escape ladder 320 is substantially parallel to the escape and maintenance platform 310. Then, slightly extend the escape ladder 320, insert the limit frame 340 into the insertion hole 3221 at the second end of the telescopic link 322, and then insert the quick-release pin to lock the limit frame 340 and the telescopic link 322. At this time, the emergency escape module 300 is in the folded state.

[0056] The second end of the telescopic link 322 and the limit frame 340 on the escape and maintenance platform 310 are detachably connected by a quick-release pin. The connection structure is simple, highly reliable, and not prone to failure, which may cause the escape ladder 320 to be unable to deploy.

[0057] See Figure 3 and Figure 4 As shown, the emergency escape module 300 further includes an escape manhole cover 350. One end of the escape manhole cover 350 is hinged to the escape opening 311 through a third pivot 333, and the other end of the escape manhole cover 350 is connected to the escape opening 311 through a bolt lock 334.

[0058] When an emergency occurs, the operation and maintenance personnel can open the bolt lock 334 and turn the escape manhole cover 350 inward to open the escape opening 311, and then deploy the escape ladder 320 to escape; during normal use, the escape manhole cover 350 closes the escape opening 311 to prevent the operation and maintenance personnel or objects from falling through the escape opening 311.

[0059] See Figure 3 As shown, the emergency escape module 300 further includes a folding pull rod 360. The first end of the folding pull rod 360 is hingedly connected to the escape maintenance platform 310, and the second end of the folding pull rod 360 is hingedly connected to the side wall 130 of the cabin 100. The connection part between the folding pull rod 360 and the escape maintenance platform 310 and the connection part between the folding pull rod 360 and the side wall 130 of the cabin 100 are both spaced from the third pivot 333.

[0060] The folding pull rod 360 includes two connecting rods that are hingedly connected, and the folding pull rod 360 can be folded or deployed. In the deployed state, the angle between the two connecting rods is approximately 180 degrees, and the folding pull rod 360 is a straight rod. The folding pull rod 360 pulls the escape maintenance platform 310 and the side wall 130 of the cabin 100, and together with the third pivot 333, limits the angle between the escape maintenance platform 310 and the intermediate layer plate 200 to be less than 180 degrees. In the folded state, the angle between the two connecting rods approaches 0 degrees, and the escape maintenance platform 310 is substantially parallel to the side wall 130 of the cabin 100 on its side.

[0061] When the escape maintenance platform 310 is deployed, the folding pull rod 360 plays a damping and decelerating role to reduce the impact force; in the deployed state, the folding pull rod 360 pulls the escape maintenance platform 310 and the side wall 130 of the cabin 100, improving the structural strength of the escape maintenance platform 310.

[0062] When it is necessary to replace the power transformation equipment in the upper cabin, a slide rail can be installed on the escape maintenance platform 310, and then the power transformation equipment is hoisted onto the slide rail. Since the angle between the escape maintenance platform 310 and the intermediate layer plate 200 is less than 180 degrees, the power transformation equipment can be easily transported into the cabin 100 through the slide rail.

[0063] In some embodiments, the emergency escape module 300 further includes a telescopic rod 370. The telescopic rod 370 connects the escape manhole cover 350 and the escape maintenance platform 310, and the connection ends of the telescopic rod 370 with the escape manhole cover 350 and the escape maintenance platform 310 are both far from the third pivot 333. The telescopic rod 370 includes a pneumatic telescopic rod, a hydraulic telescopic rod or an electric telescopic rod.

[0064] A telescopic rod 370 is provided between the emergency escape manhole cover 350 and the emergency escape maintenance platform 310, which can not only reduce the resistance to opening the emergency escape manhole cover 350, but also limit the rotation of the emergency escape manhole cover 350 to prevent the emergency escape manhole cover 350 from accidentally closing during the use of the emergency escape module 300 and injuring the operation and maintenance personnel escaping through the emergency escape module 300.

[0065] In some embodiments, the emergency escape module 300 further includes a bolt lock 334 and a positioning baffle 335. The positioning baffle 335 is arranged inside the emergency escape opening 131. In the folded state, the emergency escape maintenance platform 310 contacts the positioning baffle 335, and the positioning baffle 335 defines the inward flipping angle of the emergency escape maintenance platform 310. At the same time, in the folded state, the emergency escape maintenance platform 310 and the emergency escape opening 131 are connected by another bolt lock 334.

[0066] In the folded state, the emergency escape maintenance platform 310 contacts the positioning baffle 335, the positioning baffle 335 defines the inward flipping angle of the emergency escape maintenance platform 310, and the bolt lock 334 locks the emergency escape maintenance platform 310 to prevent the emergency escape maintenance platform 310 from unfolding in a non-emergency state.

[0067] See Figure 3 and Figure 6 As shown in, the emergency escape module 300 further includes a guardrail 380. One end of the guardrail 380 is provided with a waist eye hole 381. A positioning hole 313 is formed on the emergency escape maintenance platform 310. The positioning hole 313 and the first pivot 331 are located on opposite sides of the emergency escape opening 311. A rotating shaft 336 is arranged inside the emergency escape maintenance platform 310. The rotating shaft 336 is parallel to the emergency escape maintenance platform 310 and is located above the emergency escape maintenance platform 310. The rotating shaft 336 passes through the waist eye hole 381.

[0068] In the unfolded state, the guardrail 380 is substantially perpendicular to the emergency escape maintenance platform 310, the guardrail 380 is inserted into the positioning hole 313, and the rotating shaft 336 contacts the first end of the waist eye hole 381; in the folded state, the guardrail 380 is substantially parallel to the emergency escape maintenance platform 310, the guardrail 380 is located inside the emergency escape maintenance platform 310, and the rotating shaft 336 contacts the second end of the waist eye hole 381. When an emergency occurs, the operation and maintenance personnel can flip the guardrail 380 to make the guardrail 380 substantially perpendicular to the emergency escape maintenance platform 310, then insert the guardrail 380 into the positioning hole 313, and then open the emergency escape manhole cover 350; when the emergency is eliminated, the guardrail 380 can be lifted and flipped inward to make the guardrail 380 substantially parallel to the emergency escape maintenance platform 310.

[0069] When the emergency escape module 300 is in use, the guardrail 380 is flipped up and stands outside the emergency escape maintenance platform 310, which can prevent the operation and maintenance personnel or substation equipment from falling from the emergency escape maintenance platform 310 and reduce the safety risk.

[0070] In some embodiments, the multi-layer prefabricated cabin 10 further includes an escape door body 390 and a door closer 337. The escape door body 390 is used to open or close the escape door opening 131. One side of the escape door body 390 is hinged to the escape door opening 131, and the other side of the escape door body 390 is connected to the escape door opening 131 through a door lock 338. When the thickness of the escape ladder 320 is relatively large, a storage groove can be provided on the escape door body 390 for storing 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 body 390, and the lock hook can be provided on the side wall 130 of the cabin body 100.
