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] With the rapid development of 3D substations, the challenges of climbing between floors and replacing upper-level equipment have become increasingly prominent. Existing 3D substations have access ladders located outside the substation, which requires significant physical effort from operators carrying a large amount of tools. Furthermore, when replacing entire upper-level equipment, the process relies heavily on lifting equipment, significantly increasing O&M costs and posing significant safety risks.

[0036] 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 with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0037] See Figures 1 to 4 As shown, in this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, an intermediate layer plate 200, a lift shaft 300, and a lift 400. The cabin body 100 includes a bottom plate 110, a top plate 120, and a side wall 130 disposed between the bottom plate 110 and the top plate 120. The bottom plate 110, the top plate 120, and the side wall 130 can be connected by welding or using fasteners. The side wall 130 is a cylindrical structure with a rectangular cross-section. The bottom plate 110, the top plate 120, and the side wall 130 enclose a space for installing power transformation equipment.

[0038] n - 1 intermediate floor plates 200 are arranged inside the cabin 100. The n - 1 intermediate floor plates 200 divide the cabin 100 into n layers, where n is an integer greater than or equal to 2. For example, when n equals 2, 1 intermediate floor plate 200 divides the cabin 100 into two layers; when n equals 3, 2 intermediate floor plates 200 are arranged at intervals in the vertical direction, and the 2 intermediate floor plates 200 divide the cabin 100 into 3 layers. For the convenience of understanding, in this embodiment, the cabin 100 is divided into two layers for description. When the cabin 100 is divided into 3 layers or more, the principle is the same as when the cabin 100 is divided into two layers, so it will not be elaborated here. The first layer of the cabin 100 from bottom to top is provided with a cabin door 141 for personnel to enter and exit. The cabin door 141 is used for emergency escape on the first layer and daily entry and exit of the first layer of the cabin 100. The number of cabin doors 141 can be set according to requirements. For example, two cabin doors 141 are arranged on both sides in the width direction ( Figure 1 and Figure 2 and the up - down direction) of the cabin 100.

[0039] The lift shaft 300 runs through all the intermediate floor plates 200 and is arranged inside the cabin 100. The lift shaft 300 is a columnar space with a rectangular cross - section and can be arranged at any position inside the cabin 100. For example, the lift shaft 300 is arranged at the lower right corner of the cabin 100, and the distances between the lift shaft 300 and the right - hand side wall 130 and the lower - hand side wall 130 of the cabin 100 are 0. The elevator 400 is arranged inside the lift shaft 300 and can vertically lift to any layer. That is to say, personnel and equipment can take the elevator 400 to rise from the first layer to the second layer or descend from the second layer to the first layer.

[0040] In the existing three - dimensional substation, the boarding ladder is arranged outside the substation. When maintenance personnel carry a large number of tools to board the cabin, the physical exertion is extremely high. At the same time, when the upper - layer equipment is replaced as a whole, it is highly dependent on lifting equipment, resulting in a significant increase in operation and maintenance costs and there are relatively large potential safety hazards.

[0041] In this embodiment, the multi - layer prefabricated cabin 10 includes a cabin 100, intermediate floor plates 200, a lift shaft 300, and an elevator 400. n - 1 intermediate floor plates 200 are arranged inside the cabin 100. The n - 1 intermediate floor plates 200 divide the cabin 100 into n layers, where n is greater than or equal to 2. The lift shaft 300 runs through all the intermediate floor plates 200 and is arranged inside the cabin 100. The lift shaft 300 can be arranged at any position inside the cabin 100. The elevator 400 is arranged inside the lift shaft 300 and can vertically lift to any layer. The elevator 400 of the multi - layer prefabricated cabin 10 can vertically lift to any layer, and maintenance personnel can take the elevator 400 to lift; when the upper - layer equipment is replaced as a whole, the new equipment can be transported to the upper layer through the elevator 400, eliminating the need for a crane for hoisting, reducing the operation and maintenance costs, and eliminating the potential safety hazards of hoisting operations, that is, solving the problem of the inconvenience of maintenance personnel and equipment moving up and down between layers.

[0042] It should be noted that each intermediate layer plate 200 can be integrally arranged in the cabin body 100, but it is not limited thereto. The intermediate layer plate 200 can also extend into the side wall 130 of the cabin body 100 or penetrate through the side wall 130 of the cabin body 100 and extend outside the cabin body 100, which can be determined according to specific circumstances. That is to say, the side wall 130 can be vertically segmented. A section of the side wall 130 can be arranged between the bottom plate 110 and the intermediate layer plate 200, and a section of the side wall 130 can be arranged between the intermediate layer plate 200 and the top plate 120. The lift shaft 300 can be arranged at any position in the cabin body 100, and the distance between the lift shaft 300 and the side wall 130 of the cabin body 100 can also be greater than 0, which can be determined according to specific circumstances.

[0043] See Figures 1 to 4 As shown, the elevator 400 includes a car 410. The car 410 is a hollow cuboid box structure, and maintenance personnel and equipment can move up and down in the car 410. The car 410 is arranged in the lift shaft 300, and at least one side of the car 410 is provided with a first boarding door 420 for personnel to enter and exit any floor. For example, the lift shaft 300 is arranged at the lower right corner of the cabin body 100, and the first boarding door 420 is arranged on the left side of the car 410. The first boarding door 420 can be two sliding doors, and the two sliding doors approach or move away from each other to open or close the first boarding door 420. Maintenance personnel enter the first floor of the cabin body 100 through the cabin door 141 and can enter the car 410 through the first boarding door 420. When the car 410 rises to the second floor of the cabin body 100, the maintenance personnel can enter the second floor of the cabin body 100 through the first boarding door 420.

[0044] It should be noted that the elevator 400 includes a car 410. The car 410 is a hollow cuboid box structure, but it is not limited thereto. The elevator 400 can also include a lifting platform, and maintenance personnel and equipment move up and down on the lifting platform, which can be determined according to specific circumstances.

[0045] The elevator 400 includes a car 410, and maintenance personnel and equipment move up and down in the car 410. Compared with the solution that the elevator 400 includes a lifting platform and maintenance personnel and equipment move up and down on the lifting platform, it can prevent maintenance personnel and equipment from falling and improve the safety of personnel and equipment. In addition, the car 410 of the elevator 400 realizes the physical isolation between the upper and lower floors of the cabin body 100 and improves the protection level of the multi-layer prefabricated cabin 10. For example, when a fire occurs on the first floor or the second floor of the cabin body 100, the car 410 physically isolates the upper and lower floors of the cabin body 100, which can prevent or delay the fire, and maintenance personnel can have more time to escape, reducing the safety risk of operation and maintenance.

[0046] In some embodiments, the lift 400 further includes a lifting device (not shown) and a controller. The controller is connected to the lifting device, and the lifting device is connected to the car 410. The controller controls the car 410 to move up and down in the lift shaft 300 through the lifting device. The controller includes a working state and a standby state. In the working state, the controller can control the car 410 to stop at any floor; in the standby state, the controller can control the car 410 to stop at the first floor from bottom to top. That is to say, when the car 410 is not in use, the controller can control the car 410 to automatically return to the first floor through the lifting device.

[0047] The lift 400 has an automatic return-to-floor function. When not in use, it automatically returns to the first floor, realizing the physical isolation between the upper and lower floors of the cabin 100 and improving the protection level of the multi-layer prefabricated cabin 10.

[0048] In some embodiments, a top escape opening 430 is provided at the top of the car 410, and the top escape opening 430 can be opened or closed. During normal use, the top escape opening 430 is in a closed state to better realize the physical isolation between the upper and lower floors of the cabin 100; in an emergency, maintenance personnel on the floor above the floor where the car 410 stays (the first floor of the cabin 100) can enter the car 410 through the top escape opening 430, then enter the floor where the car 410 stays through the first boarding door 420 on one side of the car 410, and finally escape from the multi-layer prefabricated cabin 10 through the cabin door 141.

[0049] Since in an emergency, such as a fire, the lift 400 is prone to malfunction and cannot move up and down normally, a top escape opening 430 is provided at the top of the car 410 for maintenance personnel to escape in an emergency, reducing the safety risk of maintenance personnel.

[0050] See Figures 1 to 4 As shown, first and second inspection doors 440 and 450 for equipment access are provided on adjacent or opposite sides of the car 410. The first inspection door 440, the second inspection door 450, and the first boarding door 420 are provided on different sides of the car 410. A third inspection door 142 is provided on the side wall 130 of the cabin 100 opposite to the second inspection door 450. For example, the first boarding door 420 is provided on the left side of the car 410, the second inspection door 450 is provided on the right side of the car 410, the first inspection door 440 is provided on the upper side of the car 410, and the third inspection door 142 is provided on the right side wall 130 of the cabin 100.

[0051] The first maintenance door 440, the second maintenance door 450, the third maintenance door 142, and the first boarding door 420 can be sliding doors or swing doors, etc. Preferably, the first boarding door 420 is a sliding door, and the first maintenance door 440, the second maintenance door 450, and the third maintenance door 142 are swing doors. The first boarding door 420 is used for maintenance personnel to enter and exit the car 410, and the first maintenance door 440 and the second maintenance door 450 are used for equipment to enter and exit the car 410. The passage dimensions of the first maintenance door 440 and the second maintenance door 450 can be larger than those of the first boarding door 420.

[0052] During normal use, maintenance personnel can enter the first layer of the cabin body 100 through the hatch door 141 and then enter the car 410 through the first boarding door 420; when equipment needs to be replaced, the third maintenance door 142 and the second maintenance door 450 can be opened to transport the equipment into the car 410, and then the equipment can be transported to the first layer or the second layer of the cabin body 100 through the first maintenance door 440.

[0053] It should be noted that the first maintenance door 440 and the second maintenance door 450 for equipment to enter and exit are provided on two adjacent or opposite sides of the car 410. The first maintenance door 440, the second maintenance door 450, and the first boarding door 420 are arranged on different sides of the car 410, but this is not limited to this. The first maintenance door 440 can also be cancelled, and the equipment enters and exits the car 410 through the first boarding door 420, which can be determined according to the specific situation. If the first maintenance door 440 is cancelled and the equipment enters and exits the car 410 through the first boarding door 420, the passage dimensions of the first boarding door 420 can be equal to those of the second maintenance door 450.

[0054] If the first maintenance door 440 is cancelled and the equipment enters and exits the car 410 through the first boarding door 420, one maintenance door can be reduced, thereby reducing the manufacturing cost of the multi-layer prefabricated cabin 10.

[0055] In some embodiments, the second maintenance door 450 can be opened after the third maintenance door 142 is opened. Specifically, both the second maintenance door 450 and the third maintenance door 142 are connected to the controller, and the controller controls the opening sequence of the second maintenance door 450 and the third maintenance door 142, and the second maintenance door 450 can only be opened after the third maintenance door 142 is opened.

[0056] The second maintenance door 450 can be opened after the third maintenance door 142 is opened, which can prevent the second maintenance door 450 from being accidentally opened during use.

[0057] It should be noted that the second maintenance door 450 and the third maintenance door 142 can both be connected to the controller, and the controller controls the opening sequence of the second maintenance door 450 and the third maintenance door 142. However, it is not limited to this. The second maintenance door 450 can also be a single-opening or double-opening flat door. The second maintenance door 450 and the third maintenance door 142 both open outwards. The second maintenance door 450 is arranged adjacent to the third maintenance door 142. When the third maintenance door 142 is closed, since the second maintenance door 450 opens outwards and is arranged adjacent to the third maintenance door 142, there is no opening space for the second maintenance door 450, which can be determined according to the specific situation. That is to say, the opening space of the second maintenance door 450 is limited by the closed third maintenance door 142.

[0058] The opening space of the second maintenance door 450 is limited by the closed third maintenance door 142. The second maintenance door 450 and the third maintenance door 142 can be mechanical structures with simpler structures and do not require electric control equipment, which is beneficial to reducing the manufacturing cost of the multi-layer prefabricated cabin 10.

[0059] In some embodiments, at least one of the first maintenance door 440, the second maintenance door 450, the third maintenance door 142, and the first boarding door 420 is connected to the controller. Preferably, the first maintenance door 440, the second maintenance door 450, the third maintenance door 142, and the first boarding door 420 are all connected to the controller. When one of the first maintenance door 440, the second maintenance door 450, the third maintenance door 142, and the first boarding door 420 is opened, the controller controls the lifting device to stop lifting. When the controller controls the lifting device to stop lifting, the stopping position of the car 410 can be manually controlled.

[0060] When the third maintenance door 142 is opened abnormally, the controller controls the lifting device to stop lifting, avoiding the car 410 from colliding with people or objects invading the lift shaft 300, and reducing the safety risk during the operation and maintenance process. When one of the first maintenance door 440, the second maintenance door 450, and the first boarding door 420 is opened abnormally, the controller controls the lifting device to stop lifting, avoiding the accidental start of the lifting device during the process of equipment entering and leaving the car 410, and avoiding the accidental opening of one of the first maintenance door 440, the second maintenance door 450, and the first boarding door 420 during the lifting of the car 410, resulting in the fall of personnel or equipment from the car 410, and reducing the safety risk during the operation and maintenance process.

[0061] In some embodiments, the multi-layer prefabricated cabin 10 includes a surrounding wall 500 disposed inside the cabin body 100. The surrounding wall 500 and a partial side wall 130 of the cabin body 100 surround the lift shaft 300. It should be noted that the lift shaft 300 can be disposed at any position inside the cabin body 100. When there is a gap between the lift shaft 300 and the side wall 130, the surrounding wall 500 can surround the lift shaft 300. A second boarding door is provided on the surrounding wall 500 corresponding to the first boarding door 420, and the second boarding door and the first boarding door 420 are opened or closed simultaneously. A fourth maintenance door is provided on the surrounding wall 500 corresponding to the first maintenance door 440, and the fourth maintenance door and the first maintenance door 440 are opened or closed.

[0062] The surrounding wall 500 and a partial side wall 130 of the cabin body 100 surround the lift shaft 300, isolating the lift shaft 300 separately, preventing the car 410 from colliding with or invading people or objects in the lift shaft 300, and reducing the safety risk during the operation and maintenance process.

[0063] In some embodiments, the multi-layer prefabricated cabin 10 further includes an emergency floor ladder 600 connecting adjacent two floors. When the elevator 400 fails, the emergency floor ladder 600 can be used to ascend from the first floor to the second floor or descend from the second floor to the first floor. The emergency floor ladder 600 can be disposed on one side (such as the upper side) in the width direction of the lift shaft 300.

[0064] The multi-layer prefabricated cabin 10 further includes an emergency floor ladder 600. The emergency floor ladder 600 serves as a backup for the elevator 400. When the elevator 400 fails, the emergency floor ladder 600 can be used to go up to the second floor or down to the first floor to ensure the smooth progress of the operation and maintenance work. In addition, when a fire breaks out on the first floor of the cabin body 100 and it is impossible to escape from the multi-layer prefabricated cabin 10 through the cabin door 141, the emergency floor ladder 600 can be used to go up to the second floor to escape from the second floor.

[0065] When a top escape opening 430 is provided at the top of the car 410, in an emergency state, for example, when a fire breaks out on the second floor of the cabin body 100, the operation and maintenance personnel on the second floor of the cabin body 100 can enter the car 410 through the top escape opening 430, then enter the first floor of the cabin body 100 through the first boarding door 420 on one side of the car 410, and finally escape from the multi-layer prefabricated cabin 10 through the cabin door 141. In addition, when a fire breaks out in the area where the elevator 400 is located and it is impossible to escape through the top escape opening 430, the operation and maintenance personnel can also choose to go down to the first floor through the emergency floor ladder 600 and then escape from the multi-layer prefabricated cabin 10 through the cabin door 141.

[0066] In some embodiments, an emergency escape module 700 is provided on the sidewall 130 of the second layer of the cabin body 100. The emergency escape module 700 may include an escape door 710 and an escape soft ladder (not shown). The escape door 710 is a swing door that can be opened or closed. During normal use, the escape door 710 remains closed, and the escape soft ladder is stored inside the cabin body 100. In an emergency, the operation and maintenance personnel can manually open the escape door 710 and lower the escape soft ladder to escape from the multi-layer prefabricated cabin 10 through the escape soft ladder.

[0067] An emergency escape module 700 is provided on the sidewall 130 of the second layer of the cabin body 100. In an emergency, such as when a fire breaks out on the first layer of the cabin body 100, it is possible to escape from the multi-layer prefabricated cabin 10 through the emergency escape module 700, reducing the safety risks during operation and maintenance.

[0068] In some embodiments, a first cable channel 210 is provided on the intermediate layer board 200. The first cable channel 210 is used for the routing of inter-layer cables. For example, one first cable channel 210 is provided on each side of the intermediate layer board 200 in the length direction. The power transformation equipment on the upper and lower layers on the left side of the cabin body 100 is connected by routing through the first cable channel 210 on the left side, and the power transformation equipment on the upper and lower layers on the right side of the cabin body 100 is connected by routing through the first cable channel 210 on the right side. A second cable channel 111 may be provided on the bottom board 110 of the cabin body 100. The second cable channel 111 is used for external cables to enter the cabin body 100.
