Description

Technical Field

[0001] This application belongs to the field of power distribution equipment, specifically relating to a multi-layer prefabricated cabin and substation. Background Technology

[0002] Prefabricated substations are manufactured in factories, completing most of the assembly and commissioning work there, reducing on-site construction time. Compared to traditional substations, the construction cycle can be shortened by 50% or more. Meanwhile, with increasingly scarce land resources, multi-story substations with two or more floors are rapidly developing, significantly reducing the land area required. Furthermore, multi-story substations have a compact structure and rational layout, facilitating road transport and better adapting to different terrains and environments, such as narrow streets, mountainous areas, or densely built-up areas.

[0003] With the rapid development of multi-level substations, the issues of accessing upper levels and replacing equipment have become increasingly prominent. In existing multi-level substations, the access ladders are located outside the substation, requiring maintenance personnel to carry a large number of tools, resulting in significant physical exertion. Furthermore, when replacing upper-level equipment as a whole, it relies heavily on hoisting equipment, leading to a substantial increase in maintenance costs and posing significant safety hazards. Summary of the Invention

[0004] The purpose of this application is to provide a multi-layer prefabricated module and substation to solve the problem of inconvenience for operation and maintenance personnel and equipment to move up and down between layers.

[0036] 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.

[0037] See Figures 1 to 4 As shown, in this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, an intermediate floor 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 welded together or connected by 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 electrical equipment.

[0038] n-1 intermediate shelves 200 are arranged inside 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 is described with the cabin 100 divided into two layers. 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. The first layer of the cabin 100 from bottom to top is provided with a hatch 141 for personnel entry and exit. The hatch 141 is used for emergency escape and daily entry and exit of the first layer of the cabin 100. The number of hatches 141 can be set according to needs. For example, two hatches 141 are arranged in the width direction of the cabin 100 ( Figure 1 and Figure 2 Both sides (in the middle and upper directions).

[0039] An elevator shaft 300 penetrates the entire intermediate floor slab 200 and is located within the cabin 100. The elevator shaft 300 is a rectangular columnar space and can be positioned anywhere within the cabin 100. For example, the elevator shaft 300 can be located in the lower right corner of the cabin 100, with the distance between the elevator shaft 300 and the right and lower side walls 130 of the cabin 100 being zero. An elevator 400 is located within the elevator shaft 300 and can vertically ascend to any floor. That is, personnel and equipment can use the elevator 400 to ascend from the first floor to the second floor, or descend from the second floor to the first floor.

[0040] In existing multi-level substations, the access ladders are located outside the substation, requiring maintenance personnel to carry a large number of tools up the stairs, resulting in significant physical exertion. Furthermore, when replacing upper-level equipment as a whole, it relies heavily on hoisting equipment, leading to a substantial increase in maintenance costs and posing significant safety hazards.

[0041] In this embodiment, the multi-layer prefabricated cabin 10 includes a cabin body 100, intermediate floor slabs 200, elevator shafts 300, and elevators 400. n-1 intermediate floor slabs 200 are disposed within the cabin body 100, dividing the cabin body 100 into n layers, where n is greater than or equal to 2. Elevator shafts 300 penetrate all intermediate floor slabs 200 and are disposed within the cabin body 100. Elevator shafts 300 can be located at any position within the cabin body 100. Elevator 400 is disposed within elevator shafts 300 and can vertically ascend to any layer. The elevator 400 of the multi-layer prefabricated cabin 10 can vertically ascend to any layer, allowing maintenance personnel to use it for movement. When upper-layer equipment is replaced entirely, the new equipment can be transported to the upper layer via elevator 400 without the need for a crane, reducing maintenance costs and eliminating safety hazards associated with hoisting operations. This solves the problem of inconvenience for maintenance personnel and equipment moving between layers.

[0042] 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, the side wall 130 can be vertically segmented; a section of side wall 130 can be installed between the bottom plate 110 and the intermediate shelf 200, and a section of side wall 130 can be installed between the intermediate shelf 200 and the top plate 120. The elevator shaft 300 can be installed at any position within the cabin 100, and the distance between the elevator shaft 300 and the side wall 130 of the cabin 100 can also be greater than zero, depending on the specific circumstances.

[0043] See Figures 1 to 4 As shown, the elevator 400 includes a car 410, which is a hollow rectangular box structure. Maintenance personnel and equipment can move up and down within the car 410. The car 410 is located within an elevator shaft 300, and at least one side of the car 410 has a first boarding door 420 for personnel to enter and exit any floor. For example, the elevator shaft 300 is located in the lower right corner of the cabin 100, and the first boarding door 420 is located on the left side of the car 410. The first boarding door 420 can be two sliding doors, which can be moved closer together or further apart to open or close the first boarding door 420. Maintenance personnel enter the first floor of the cabin 100 through the 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 100, maintenance personnel can also enter the second floor through the first boarding door 420.

[0044] It should be noted that the elevator 400 includes a car 410, which is a hollow rectangular box structure, but is not limited to this. The elevator 400 may also include a lifting platform, on which maintenance personnel and equipment are lifted and lowered, depending on the specific circumstances.

[0045] The elevator 400 includes a car 410, within which maintenance personnel and equipment move up and down. Compared to a system where the elevator 400 includes a lifting platform, where maintenance personnel and equipment move up and down on the platform, this design prevents falls and improves personnel and equipment safety. Furthermore, the car 410 of the elevator 400 provides physical isolation between the upper and lower levels of the cabin 100, enhancing the protection level of the multi-story prefabricated cabin 10. For example, in the event of a fire on the first or second level of the cabin 100, the physical isolation of the car 410 between the upper and lower levels can prevent or delay the spread of the fire, giving maintenance personnel more time to escape and reducing safety risks during maintenance.

[0046] In some embodiments, the elevator 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 within the elevator shaft 300 via 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, when the car 410 is not in use, the controller can control the car 410 to automatically return to the first floor via the lifting device.

[0047] The elevator 400 has an automatic return function. When no one is using it, it automatically returns to the first floor, realizing physical isolation between the upper and lower floors of the cabin 100 and improving the protection level of the multi-story prefabricated cabin 10.

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

[0049] Because the elevator 400 is prone to malfunction and cannot operate normally in emergency situations, such as during a fire, a top escape hatch 430 is provided on the top of the car 410 for maintenance personnel to escape in emergency situations, reducing the safety risks for maintenance personnel.

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

[0051] The first inspection door 440, the second inspection door 450, the third inspection 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 inspection door 440, the second inspection door 450, and the third inspection 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 inspection door 440 and the second inspection door 450 are used for equipment to enter and exit the car 410. The passage size of the first inspection door 440 and the second inspection door 450 can be larger than the passage size of the first boarding door 420.

[0052] In normal use, maintenance personnel can enter the first floor of the cabin 100 through the hatch 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 first maintenance door 440 can be used to transport the equipment to the first or second floor of the cabin 100.

[0053] It should be noted that the car 410 has a first maintenance door 440 and a second maintenance door 450 on adjacent or opposite sides for equipment entry and exit. The first maintenance door 440, the second maintenance door 450, and the first boarding door 420 are located on different sides of the car 410, but are not limited to this. The first maintenance door 440 may also be omitted, and the equipment may enter and exit the car 410 through the first boarding door 420, depending on the specific circumstances. If the first maintenance door 440 is omitted, and the equipment enters and exits the car 410 through the first boarding door 420, the passage size of the first boarding door 420 may be equal to the passage size of the second maintenance door 450.

[0054] The first maintenance door 440 is eliminated, and the equipment enters and exits the car 410 through the first boarding door 420, which reduces one maintenance door and thus reduces the manufacturing cost of the multi-story prefabricated cabin 10.

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

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

[0057] It should be noted that both the second inspection door 450 and the third inspection door 142 can be connected to a controller, which controls the opening sequence of the second inspection door 450 and the third inspection door 142. However, this is not a limitation; the second inspection door 450 can also be a single or double swing door. Both the second inspection door 450 and the third inspection door 142 open outwards, with the second inspection door 450 positioned adjacent to the third inspection door 142. When the third inspection door 142 is closed, because the second inspection door 450 is open outwards and positioned adjacent to the third inspection door 142, the second inspection door 450 has no opening space. This can be determined depending on the specific circumstances. In other words, the opening space of the second inspection door 450 is limited by the closed third inspection door 142.

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

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

[0060] When the third inspection door 142 is opened abnormally, the controller stops the lifting device to prevent the car 410 from colliding with or intruding people or objects into the elevator shaft 300, thus reducing safety risks during operation and maintenance. When any of the first inspection door 440, the second inspection door 450, or the first boarding door 420 is opened abnormally, the controller stops the lifting device to prevent the lifting device from accidentally starting during equipment entry and exit from the car 410, and to prevent any of the first inspection door 440, the second inspection door 450, or the first boarding door 420 from accidentally opening during the lifting of the car 410, which could cause personnel or equipment to fall from the car 410, thus reducing safety risks during operation and maintenance.

[0061] In some embodiments, the multi-story prefabricated cabin 10 includes a perimeter wall 500 disposed within the cabin body 100. The perimeter wall 500 and a portion of the sidewalls 130 of the cabin body 100 surround the elevator shaft 300. It should be noted that the elevator shaft 300 can be located at any position within the cabin body 100. When a gap is formed between the elevator shaft 300 and the sidewalls 130, the perimeter wall 500 can surround the elevator shaft 300. A second boarding door is provided on the perimeter wall 500 corresponding to the first boarding door 420. The second boarding door and the first boarding door 420 can be opened or closed simultaneously. A fourth maintenance door is provided on the perimeter wall 500 corresponding to the first maintenance door 440. The fourth maintenance door and the first maintenance door 440 can be opened or closed simultaneously.

[0062] The perimeter wall 500 and part of the side wall 130 of the cabin 100 surround the elevator shaft 300, isolating the elevator shaft 300 separately, preventing the car 410 from colliding with or intruding people or objects into the elevator shaft 300, and reducing safety risks during operation and maintenance.

[0063] In some embodiments, the multi-story prefabricated cabin 10 further includes an emergency staircase 600 connecting two adjacent floors. In the event of a malfunction of the elevator 400, the emergency staircase 600 allows passage from the first floor to the second floor, or from the second floor to the first floor. The emergency staircase 600 may be located on one side (e.g., the upper side) of the elevator shaft 300 in the width direction.

[0064] The multi-story prefabricated cabin 10 also includes an emergency staircase 600, which serves as a backup for the elevator 400. In the event of a malfunction of the elevator 400, the emergency staircase 600 allows access to the second floor or the first floor, ensuring smooth operation and maintenance. Furthermore, in the event of a fire on the first floor of the cabin 100 and evacuation from the multi-story prefabricated cabin 10 through the cabin door 141 is impossible, the emergency staircase 600 allows access to the second floor for escape.

[0065] When the top of the elevator car 410 is equipped with a top escape hatch 430, in an emergency, such as when a fire occurs on the second floor of the cabin 100, maintenance personnel on the second floor of the cabin 100 can enter the elevator car 410 through the top escape hatch 430, then enter the first floor of the cabin 100 through the first boarding door 420 on one side of the elevator car 410, and finally escape the multi-story prefabricated cabin 10 through the hatch 141. Furthermore, if a fire occurs in the area where the elevator 400 is located, and escape is not possible through the top escape hatch 430, maintenance personnel can also choose to descend to the first floor via the emergency staircase 600, and then escape the multi-story prefabricated cabin 10 through the hatch 141.

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

[0067] An emergency escape module 700 is installed on the side wall 130 of the second layer of the cabin 100. In an emergency, such as when a fire occurs on the first layer of the cabin 100, the multi-layer prefabricated cabin 10 can be escaped 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 plate 200 for inter-layer cable routing. For example, one first cable channel 210 is provided on each side of the intermediate layer plate 200 along its length. The power equipment on the upper and lower layers of the left side of the cabin 100 is connected through the first cable channel 210 on the left side, and the power equipment on the upper and lower layers of the right side of the cabin 100 is connected through the first cable channel 210 on the right side. A second cable channel 111 may be provided on the bottom plate 110 of the cabin 100 for external cables to enter the cabin 100. The number and position of the second cable channels 111 can correspond to the first cable channels 210, that is, one second cable channel 111 is provided below each first cable channel 210.

[0069] Cable channels are provided on the intermediate layer plate 200 and the bottom plate 110 to facilitate external wiring into the cabin 100 and electrical connection of the power equipment between the upper and lower layers of the cabin 100.

[0070] In some embodiments, the multi-layer prefabricated cabin 10 is along the length direction ( Figure 1 and Figure 2 The multi-layer prefabricated module 10 is divided into multiple sections (either in the left-right or width direction) and adjacent sections are connected by welding or fasteners. For example, the multi-layer prefabricated module 10 is divided into two sections along its length: a first section 11 on the left and a second section 12 on the right. The first section 11 and the second section 12 are welded together. It should be understood that, based on the dimensions of the multi-layer prefabricated module 10 in the length or width direction, the multi-layer prefabricated module 10 can be divided into multiple sections along its length or width direction. Similarly, based on the dimensions of the multi-layer prefabricated module 10 in the height direction, the multi-layer prefabricated module 10 can also be divided into multiple sections along its height direction.

[0071] The multi-layer prefabricated cabin 10 is divided into multiple sections along its length, which can realize modular division. On the one hand, it can be prefabricated in the factory to shorten the construction cycle of the substation, and on the other hand, it can reduce the difficulty and cost of road transportation.

[0072] This application also provides a substation, which includes a multi-story prefabricated cabin 10 and power equipment, the power equipment being installed within the multi-story prefabricated cabin 10.

[0073] For example, a first cable channel 210 and a second cable channel 111 are provided in the middle area of ​​the first section 11 in the width direction.
