[0040] 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.

[0041] See also Figures 1 to 3As shown, the prefabricated cabin 10 in this embodiment includes a cabin body 100, a transverse partition 200, and a longitudinal partition 300. The cabin body 100 includes a top plate 111, a bottom plate 112, and side plates 113 arranged around the edges of the top plate 111 and the bottom plate 112. The transverse partition 200 is arranged in the cabin body 100, and the transverse partition 200 and the bottom plate 112 are arranged roughly parallel. The transverse partition 200 separates the inner cavity of the cabin body 100 into the equipment layer 101 and the cable mezzanine 102, and the transverse partition 200 is provided with a first ventilation port 210 connecting the equipment layer 101 and the cable mezzanine 102.

[0042] At least one longitudinal partition 300 is provided in the equipment layer 101. The longitudinal partition 300 divides the equipment layer 101 into a shaft area and an equipment area 1011. The shaft area is connected to the cable mezzanine 102. The side panels 113 on opposite sides of the cabin 100 are each provided with a second vent 1131. The second vent 1131 on at least one side is connected to the outside of the cabin 100 and the shaft area. For example, the longitudinal partition 300 and the side panel 113 on the left side of the cabin 100 form the shaft area. The second vent 1131 is provided on the side panel 113 on the left side of the cabin 100 and on the side panel 113 on the right side of the cabin 100. The second vent 1131 on the left side is connected to the shaft area, and the second vent 1131 on the right side is connected to the outside of the cabin 100 and the equipment area 1011.

[0043] When the prefabricated cabin 10 is used in a substation, the substation equipment is installed in the equipment area 1011, and the cables are introduced from the cable trench into the cable interlayer 102, and then pass through the transverse partition 200 to connect with the substation equipment in the equipment area 1011. During the operation of the substation, the air mixed with dust from the outside of the prefabricated cabin 10 enters the shaft area and the cable interlayer 102 from the second vent 1131 on the left side. The dust in the air is decelerated and deposited in the cable interlayer 102. The clean air enters the equipment area 1011 through the first vent 210 on the transverse partition 200, and finally flows out through the second vent 1131 on the right side. It should be noted that, in order to enhance the effect of the shaft area and the cable interlayer 102 on decelerating and filtering dust in the air, the shaft area and the cable interlayer 102 can also be provided with filtering devices such as filter screens and electrostatic dust removal devices.

[0044] In existing prefabricated substations, the interior and exterior of the prefabricated cabin are directly connected through ventilation holes. Dust from the external environment can enter the prefabricated cabin through the ventilation holes, affecting the safety of equipment operation in the prefabricated cabin.

[0045] In this embodiment, the prefabricated cabin 10 includes a cabin body 100, a transverse partition 200 and a longitudinal partition 300. The cabin body 100 includes a top plate 111, a bottom plate 112 and a side plate 113 arranged around the edges of the top plate 111 and the bottom plate 112. The transverse partition 200 is arranged in the cabin body 100. The transverse partition 200 separates the inner cavity of the cabin body 100 into an equipment layer 101 and a cable mezzanine 102. A first ventilation port 210 connecting the equipment layer 101 and the cable mezzanine 102 is provided on the transverse partition 200. At least one longitudinal partition 300 is arranged in the equipment layer 101. The longitudinal partition 300 separates the equipment layer 101 into a shaft area and an equipment area 1011. The shaft area and the cable mezzanine 102 are connected. A side plate 113 of the cabin body 100 is provided with a second ventilation port 1131. The outside of the cabin body 100 and the shaft area are connected through the second ventilation port 1131. Since the second ventilation port 1131 on the side panel 113 is indirectly connected to the equipment area 1011 through the shaft area and the cable interlayer 102, the shaft area and the cable interlayer 102 can slow down and filter the dust in the air, so that the dust is deposited in the shaft area and the cable interlayer 102, thereby reducing the dust from entering the interior of the prefabricated cabin 10, ensuring the cleanliness of the air in the equipment area 1011 in the cabin, and improving the safety of equipment operation in the prefabricated cabin 10.

[0046] In addition, the cables are introduced from the moist cable trench into the cable interlayer 102 and then pass through the transverse partition 200 to be connected to the substation equipment in the equipment area 1011, which reduces the entry of moisture in the cable trench into the equipment area 1011 and can slow down or even eliminate the condensation problem.

[0047] In some embodiments, two longitudinal partitions 300 are spaced apart within the equipment layer 101, with the equipment area 1011 located in the middle of the length of the equipment layer 101, and the vertical shaft areas located on both sides of the length of the equipment area 1011. The second vents 1131 on each side communicate with the cable mezzanine 102 through the vertical shaft areas.

[0048] The second ventilation openings 1131 on each side are connected to the cable interlayer 102 through the vertical shaft area. No matter how the wind direction outside the prefabricated cabin 10 changes, the air flows in from the second ventilation openings 1131 on the right side, which can ensure that the dust mixed in the air is deposited in the vertical shaft area and the cable interlayer 102, reducing the dust from entering the interior of the prefabricated cabin 10 and ensuring the cleanliness of the air in the equipment area 1011 in the cabin.

[0049] In some embodiments, the prefabricated cabin 10 further includes a central partition 400, which is arranged approximately parallel to the bottom plate 112. The central partition 400 divides the interior of the cabin 100 into multiple equipment layers 101. The cable interlayer 102 is located below the first equipment layer 101. The longitudinal partition 300 is located within the first equipment layer 101. The second vent 1131 is located on the side panel 113 of the first equipment layer 101. Second vents 1131 may be provided on the side panels 113 of the second equipment layer 101 and above. However, this is not a limitation. Alternatively, passage holes may be provided on the central partition 400 to interconnect the multiple equipment layers 101. The specific configuration may vary depending on the specific situation.

[0050] In some embodiments, the prefabricated cabin 10 also includes a cable box 500, which is arranged outside the cabin body 100. The cable box 500 connects the vertical shaft area and the cable trench. The height of the connection between the cable box 500 and the cabin body 100 is greater than the height of the transverse partition 200.

[0051] The height of the connection between the cable box 500 and the cabin body 100 can be set according to the water level line in flood weather at the substation location to ensure that the water outside the prefabricated cabin 10 cannot penetrate into the prefabricated cabin 10 through the connection between the cable box 500 and the cabin body 100, thereby avoiding water entering the prefabricated cabin 10 and causing power outages in the substation.

[0052] In some embodiments, the height of the connection between the cable box 500 and the cabin body 100 is greater than or equal to the height of the second vent 1131 .

[0053] The height of the connection between the cable box 500 and the cabin body 100 and the height of the second vent 1131 can be set according to the water level line in flood weather at the substation location to ensure that the water accumulated outside the prefabricated cabin 10 cannot penetrate into the prefabricated cabin 10 through the connection between the cable box 500 and the cabin body 100 and the second vent 1131, thereby avoiding water entering the prefabricated cabin 10 and causing power failure in the substation.

[0054] In some embodiments, the prefabricated cabin 10 further includes a partitioning plate 600 disposed within the shaft area. The partitioning plate 600 separates the shaft area into a ventilation shaft 1012 and a cable shaft 1013. The ventilation shaft 1012 communicates with the cable interlayer 102, the second vent 1131 communicates with the ventilation shaft 1012, and the cable box 500 communicates with the cable shaft 1013. The cable shaft 1013 can be disposed in the middle of the shaft area in the width direction, and the ventilation shaft 1012 can be disposed on both sides of the cable shaft 1013 in the width direction.

[0055] A relief groove 220 and a third ventilation opening 230 are also provided on the transverse partition 200. The orthographic projection of the cable shaft 1013 on the transverse partition 200 is located in the relief groove 220. The ventilation shaft 1012 and the cable interlayer 102 are connected through the third ventilation opening 230. The orthographic projection of the third ventilation opening 230 on the transverse partition 200 is located in the orthographic projection of the ventilation shaft 1012 on the transverse partition 200.

[0056] A larger clearance groove 220 is provided on the transverse partition 200 to leave enough space for cables to enter and exit the cable interlayer 102; a larger third ventilation port 230 is provided on the transverse partition 200, which is conducive to reducing the air flow rate, allowing dust to be deposited in the shaft area and the cable interlayer 102, thereby reducing the entry of dust into the interior of the prefabricated cabin 10.

[0057] In some embodiments, the prefabricated cabin 10 further includes a cable box 700. This box is located on the side of the transverse partition 200 away from the cable mezzanine 102 and communicates with the cable mezzanine 102. The cable box 700 is used to connect to power transformers. Cables in the cable trench are connected to the cable box 700 via the cable box 500, the cable well 1013, and the cable mezzanine 102. The power transformers are all connected to the cable box 700.

[0058] The prefabricated cabin 10 also includes a cable box 700, and the power transformation equipment is all connected to the cable box 700. The height of the cable box 700 is greater than the height of the cable interlayer 102, further improving the protection level.

[0059] In some embodiments, the prefabricated cabin 10 further includes a dust cleaning device, which is connected to the cable interlayer 102 and is used to discharge dust deposited in the cable interlayer 102 .

[0060] The dust deposited in the ventilation shaft 1012 and the cable interlayer 102 is regularly removed by using a dust cleaning device, so as to prevent the dust deposited in the cable interlayer 102 from being sucked into the equipment area 1011 .

[0061] In some embodiments, the prefabricated cabin 10 further includes a water level monitoring device and a drainage device. The water level monitoring device is disposed in the cable interlayer 102 , and the drainage device is connected to the cable interlayer 102 for draining the accumulated water in the cable interlayer 102 .

[0062] When the water level monitoring device detects that water has entered the cable interlayer 102 and the water level has reached a preset height, the drainage device is activated to drain water, thereby preventing the accumulated water in the cable interlayer 102 from seeping into the equipment area 1011, thereby further improving the protection level.

[0063] See also Figures 4 to 7As shown, the cabin 100 includes N cabin sections 110 and N-1 plug-in devices, where N is an integer greater than or equal to 2. The N cabin sections 110 are arranged in sequence along the length direction, and adjacent cabin sections 110 are detachably connected through plug-in devices. In other words, the top plate 111, the bottom plate 112 and the two side panels 113 opposite in the width direction of the cabin 100 are divided into N sections. Each cabin section 110 includes two side panels 113 opposite in the width direction, and the side of the first cabin section 110 away from the second cabin section 110 and the side of the Nth cabin section 110 away from the N-1th cabin section 110 are further provided with side panels 113 in the length direction. The transverse partitions 200 and the middle partitions 400 are also divided into N sections accordingly.

[0064] The plug-in connector includes a female connector assembly 120 and a male connector assembly 130. The female connector assembly 120 is located at the junction of the Mth and M+1th compartments 110, where M+1 is less than or equal to N. A positioning groove 1221 is provided on the inner side of the female connector assembly 120, with the opening of the positioning groove 1221 facing the inner side of the compartment 100. The male connector assembly 130 is located at the junction of the M+1th and Mth compartments 110. A positioning boss 1321 is provided on the outer side of the male connector assembly 130, which is located within the positioning groove 1221.

[0065] During assembly of the prefabricated cabin 10, the first cabin section 110 is placed on the foundation 20, and the second cabin section 110 is hoisted so that the positioning boss 1321 of the male assembly 130 of the second cabin section 110 is aligned with the positioning groove 1221 of the female groove assembly 120. The second cabin section 110 is then slowly lowered and the male assembly 130 is inserted into the female groove assembly 120, thereby completing the splicing of the first and second cabin sections 110. To facilitate assembly, the lower end of the positioning boss 1321 of the male assembly 130 can be chamfered or rounded to facilitate quick positioning.

[0066] Adjacent compartments 110 are detachably connected via plug-in connectors, reducing the on-site assembly workload, shortening the substation construction period, and facilitating secondary disassembly and modification. Furthermore, the detachable connection of adjacent compartments 110 via plug-in connectors does not damage the structure of the prefabricated compartment 10, improving the prefabricated compartment's 100 wind and earthquake resistance and reducing the risk of power outages due to substation failures.

[0067] In some embodiments, both the female trough assembly 120 and the male assembly 130 are bent into a U-shaped structure, which includes two cantilevered portions and a connecting portion connecting the two cantilevered portions. That is, both the female trough assembly 120 and the male assembly 130 include a cantilevered portion and a connecting portion. The connecting portion of the female trough assembly 120 is connected to the bottom plate 112 of the Mth compartment 110, and the cantilevered portion of the female trough assembly 120 is connected to the side plate 113 of the Mth compartment 110. The connecting portion of the male assembly 130 is connected to the bottom plate 112 of the M+1th compartment 110, and the cantilevered portion of the male assembly 130 is connected to the side plate 113 of the M+1th compartment 110.

[0068] The female trough assembly 120 and the male assembly 130 are both bent into a U-shaped structure, that is, the female trough assembly 120 and the male assembly 130 are arranged along the edges of the side panels 113 and the bottom panel 112 of the cabin body 100, and the side panels 113 and the bottom panels 112 of adjacent cabin sections 110 are connected, thereby improving the connection strength, which is beneficial to improving the wind resistance and earthquake resistance of the prefabricated cabin 10.

[0069] It should be noted that the female trough assembly 120 and the male assembly 130 can both be bent into a U-shaped structure, and the female trough assembly 120 and the male assembly 130 are arranged along the edges of the side panels 113 and the bottom panel 112 of the cabin body 100, but are not limited to this. The female trough assembly 120 and the male assembly 130 can also be arranged only on the edges of the side panels 113, depending on the specific situation.

[0070] In some embodiments, the female channel assembly 120 includes a channel steel 121 and a first locating member 122. The channel steel 121 has a U-shaped cross-section. The opening of the groove of the channel steel 121 faces the male assembly 130. The cantilever portion on one side of the channel steel 121 is connected to the M-th compartment 110, while the cantilever portion on the other side of the channel steel 121 contacts or fits with a small clearance with the M+1 compartment 110. The first locating member 122 is partially disposed within the groove of the channel steel 121 and partially located outside the groove of the channel steel 121. The first locating member 122 can be formed by bending a metal plate. The ends of the metal plate are bent toward the side near the channel steel 121, forming flanges located inside the cantilever portion of the channel steel 121. The center area of ​​the first locating member 122 is recessed toward the connection portion near the channel steel 121 to form a locating groove 1221. The end surface of the first locating member 122 near the male assembly 130 is located outside the groove of the channel steel 121 to prevent interference between the cantilever portion of the channel steel 121 and the male assembly 130.

[0071] The male connector assembly 130 includes a rectangular tube 131 and a second locating member 132. One side of the rectangular tube 131 is connected to the M+1 compartment 110, while the other side of the rectangular tube 131 is in contact with or has a small clearance fit with the M compartment 110. The second locating member 132 is positioned on the side of the rectangular tube 131 near the female connector assembly 120. The second locating member 132 can be formed by bending a metal sheet. The center of the second locating member 132 protrudes away from the rectangular tube 131 to form a locating boss 1321.

[0072] An assembly gap is formed between the first positioning member 122 and the second positioning member 132. Specifically, the positioning groove 1221 and the positioning boss 1321 form an assembly gap, and an assembly gap is formed between the opposite end surfaces of the first positioning member 122 and the second positioning member 132.

[0073] An assembly gap is formed between the first positioning member 122 and the second positioning member 132 to prevent adjacent compartments 110 from being unable to be smoothly plugged in due to factors such as assembly errors and hoisting deformation.

[0074] In some embodiments, the plug-in device further includes a waterstop 140. A receiving groove 1322 is provided on the top surface of the positioning boss 1321 opposite the bottom surface of the positioning groove 1221. The waterstop 140 is disposed within the receiving groove 1322 and contacts the bottom surface of the positioning groove 1221. The cross-sections of the receiving groove 1322, the positioning groove 1221, and the waterstop 140 are all rectangular. The thickness of the waterstop 140 is greater than the depth of the receiving groove 1322, meaning that the waterstop 140 is partially located within the receiving groove 1322 and partially located outside the receiving groove 1322. The fact that the waterstop 140 is partially located within the receiving groove 1322 and partially located outside the receiving groove 1322 prevents the waterstop 140 from failing to press against the bottom surface of the positioning groove 1221, thereby affecting the waterstop 140's ability to prevent damage. The waterstop 140 is a water-swelling structural component, meaning that the waterstop 140 can be made of a water-swelling material.

[0075] A water stop strip 140 is provided between the top surface of the positioning boss 1321 and the bottom surface of the positioning groove 1221. When water accumulates outside the prefabricated cabin 10 or it rains, the seeping water contacts the water stop strip 140, causing the water stop strip 140 to expand, thereby pressing the bottom surface of the positioning groove 1221, preventing water accumulation outside the prefabricated cabin 10 or rainwater from seeping into the interior of the prefabricated cabin 10, thereby reducing the risk of power outages due to substation failures.

[0076] It should be noted that the cross-sections of the accommodating groove 1322, the positioning groove 1221 and the water stop strip 140 are all rectangular, but are not limited to this. The cross-sections of the accommodating groove 1322, the positioning groove 1221 and the water stop strip 140 can also be trapezoidal or other shapes, depending on the specific situation.

[0077] In some embodiments, the plug-in device further includes a push plate 150 and a push bolt 160. The push plate 150 is disposed at the bottom of the receiving groove 1322. The water stop strip 140 is disposed between the push plate 150 and the bottom surface of the positioning groove 1221. The push bolt 160 is disposed within the male assembly 130 and is used to push the push plate 150 to compress the water stop strip 140. Specifically, a process hole 1311 may be provided in the rectangular tube 131, and a threaded hole may be provided at the bottom of the receiving groove 1322 of the second positioning member 132. The push bolt 160 may be installed in the threaded hole at the bottom of the receiving groove 1322 through the process hole 1311. Because the rectangular tube 131 is disposed on the inside, even if the process hole 1311 is provided in the rectangular tube 131, water will not seep through the process hole 1311.

[0078] When assembling the prefabricated cabin 10, before the adjacent cabin sections 110 are plugged in, the length of the push bolt 160 extending into the receiving groove 1322 is relatively short, and there is a large gap between the water stop strip 140 and the bottom surface of the positioning groove 1221, to avoid the influence of factors such as assembly errors and lifting deformation, which may cause the adjacent cabin sections 110 to be unable to be plugged in smoothly; after the adjacent cabin sections 110 are plugged in, the push bolt 160 can be rotated through the process hole 1311 to increase the length of the push bolt 160 extending into the receiving groove 1322, thereby pushing the push plate 150 to squeeze the water stop strip 140, so that the water stop strip 140 is close to the bottom surface of the positioning groove 1221.

[0079] The plug-in device also includes a push plate 150 and a push bolt 160. The position of the water stop strip 140 can be adjusted by the push plate 150 and the push bolt 160, so that a gap is formed between the water stop strip 140 and the bottom surface of the positioning groove 1221 during assembly, ensuring that the adjacent cabin sections 110 can be plugged in smoothly, and that the water stop strip 140 is close to the bottom surface of the positioning groove 1221 after assembly, thereby avoiding water seepage at the joints of the prefabricated cabin 10.

[0080] It should be noted that the female channel assembly 120 and the male head assembly 130 are both bent into a U-shaped structure. The cantilever portion of the female channel assembly 120 and the male head assembly 130 (the portion connected to the side plate 113) can be provided with a push plate 150 and a push bolt 160, while the connection portion of the female channel assembly 120 and the male head assembly 130 (the portion connected to the bottom plate 112) does not need to be provided with a push plate 150 and a push bolt 160. Figure 7 As shown, the plug-in device is connected to the base plate 112, with the male component 130 on top and the female groove component 120 on the bottom. The water stop strip 140 can be tightened by the male component 130, and there is no need to additionally set up the push plate 150 and the push bolt 160.

[0081] In some embodiments, the cantilever portion on the first side of the channel steel 121 is welded to the Mth compartment 110, and the cantilever portion on the second side of the channel steel 121 is in contact with or has a small gap with the M+1th compartment 110. The first side of the rectangular tube 131 is welded to the M+1th compartment 110, and the second side of the rectangular tube 131 is in contact with or has a small gap with the Mth compartment 110. Waterproof paint or glue can be applied between the cantilever portion on the second side of the channel steel 121 and the M+1th compartment 110, as well as between the second side of the rectangular tube 131 and the Mth compartment 110, to form a first layer of waterproofing, and the waterstop 140 serves as a second layer of waterproofing.

[0082] The first layer of waterproofing is formed on the outside of the joints of the prefabricated cabin 10 by painting or gluing, and a water stop strip 140 is set between the top surface of the positioning boss 1321 and the bottom surface of the positioning groove 1221 to form a second layer of waterproofing. The double-layer waterproofing improves the waterproofing level and further avoids water seepage at the joints of the prefabricated cabin 10.

[0083] The present application also provides a substation, which includes the prefabricated cabin 10 disclosed above and power transformation equipment, and the power transformation equipment is arranged in the prefabricated cabin 10.

[0084] In this embodiment, the substation includes a prefabricated cabin 10, which includes a cabin body 100, a transverse partition 200 and a longitudinal partition 300. The cabin body 100 includes a top plate 111, a bottom plate 112 and a side plate 113 arranged around the edges of the top plate 111 and the bottom plate 112. The transverse partition 200 is arranged in the cabin body 100, and the transverse partition 200 separates the inner cavity of the cabin body 100 into an equipment layer 101 and a cable mezzanine 102. A first ventilation port 210 connecting the equipment layer 101 and the cable mezzanine 102 is provided on the transverse partition 200. At least one longitudinal partition 300 is arranged in the equipment layer 101, and the longitudinal partition 300 separates the equipment layer 101 into a shaft area and an equipment area 1011. The shaft area and the cable mezzanine 102 are connected. A side plate 113 of the cabin body 100 is provided with a second ventilation port 1131, and the outside of the cabin body 100 and the shaft area are connected through the second ventilation port 1131. Since the second ventilation port 1131 on the side panel 113 is indirectly connected to the equipment area 1011 through the shaft area and the cable interlayer 102, the shaft area and the cable interlayer 102 can slow down and filter the dust in the air, so that the dust is deposited in the shaft area and the cable interlayer 102, thereby reducing the dust from entering the interior of the prefabricated cabin 10, ensuring the cleanliness of the air in the equipment area 1011 in the cabin, and improving the safety of equipment operation in the prefabricated cabin 10.

[0085] See also Figure 8 and Figure 9As shown, the substation further includes a waterproof gasket 30. The prefabricated cabin 10 is disposed on the foundation 20, and the waterproof gasket 30 is disposed between the foundation 20 and the prefabricated cabin 10. The waterproof gasket 30 seals at least the joint between the Mth cabin section 110 and the M+1th cabin section 110. For example, the shape of the foundation 20 matches the vertical projection of the side panels 113 and the joint, and the waterproof gasket 30 is disposed on the interface between the foundation 20 and the prefabricated cabin 10.

[0086] For the joints between adjacent side panels 113 of the prefabricated cabin 10, waterproof paint or glue can be applied between the cantilever portion of the second side of the channel steel 121 and the M+1 compartment section 110, as well as between the second side of the rectangular tube 131 and the M compartment section 110, to form a first layer of waterproofing on the side; a water stop strip 140 is provided between the top surface of the positioning boss 1321 and the bottom surface of the positioning groove 1221 to form a second layer of waterproofing. For the joints between adjacent bottom panels 112 of the prefabricated cabin 10, after the prefabricated cabin 10 is assembled, the joints are blocked by the prefabricated cabin 10, making it inconvenient to apply waterproof paint or glue. A waterproof sealing gasket 30 is provided between the foundation 20 and the prefabricated cabin 10 to form the first layer of waterproofing at the bottom, preventing water from seeping into the bottom of the prefabricated cabin 10 and extending into the cabin body 100 through the bottom joints, thereby further improving the waterproofing level of the prefabricated cabin 10.
