Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a prefabricated cabin-type switchgear which is convenient for later equipment to enter the cabin. Background Art

[0002] The prefabricated cabin switchgear is manufactured and processed into a prefabricated cabin, and the switch cabinet and the prefabricated cabin are integrated and installed. The installation of the switch cabinet and the connection between the cabinets are completed in the factory. The prefabricated cabin and the switch cabinet are then transported to the substation site together. After the cabin is in place on site, it can be powered on. The on-site civil construction time is reduced and the construction period is saved.

[0003] When considering reserving equipment for entry into traditional prefabricated cabins later, a large fire door is usually reserved on the cabin body. This method usually has certain hidden dangers. First, the large door usually has a certain impact on the strength of the cabin structure. The door itself is also at risk of deformation during transportation due to its large size. The main purpose of reserving this door is only for the entry of equipment into the cabin. Under normal circumstances, it will not be opened, resulting in certain waste. There is also a risk of water and dust entering. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a prefabricated cabin switch device that is convenient for later equipment to enter. The prefabricated cabin is designed with detachable walls and a detachable cabin roof to meet the needs of later equipment entering the cabin. The overall structure is compact and strict, and the strength is higher.

[0005] The present invention is realized through the following technical solution: a prefabricated cabin-type switchgear which is convenient for later equipment to enter the cabin, the prefabricated cabin comprising a cabin body and a cabin roof, the cabin roof comprising a plurality of supporting frames and a top plate, the plurality of supporting frames being arranged along the length direction of the cabin body and being detachably fixed to the cabin body top, the adjacent supporting frames being fixedly connected by a plurality of connecting beams, the supporting frames being a triangular frame structure, the top plate being laid on the two inclined surfaces of the triangular frame structure.

[0006] The cabin roof of this solution is detachably connected to the cabin body through the support frame, which is convenient for disassembly and assembly, meeting the needs of large equipment entering the cabin in the future. The stability and structural strength between the support frames are enhanced by connecting beams, and the top plate is laid on two inclined surfaces to form a drainage slope.

[0007] As an optimization, the support frame includes a first crossbeam and two diagonal bracing beams. The two ends of the first crossbeam are detachably fixed to the tops of the long sides of the cabin. A vertical support rod is fixed to the top center of the first crossbeam. One end of each of the two diagonal bracing beams is fixed to the upper end of the support rod, and the other ends of the two diagonal bracing beams are respectively fixed to the two ends of the first crossbeam. Multiple diagonal bracing rods are fixed between the diagonal bracing beams and the first crossbeam. The top plate is laid on multiple parallel and adjacent diagonal bracing beams of the support frame. This optimization solution achieves a detachable connection by screwing the first crossbeam to the cabin top. The two diagonal bracing beams facilitate the installation of the top plate to form a drainage slope. The support rods support one end of the two diagonal bracing beams to maintain stability. The multiple diagonal bracing rods improve the structural strength and bending resistance of the support frame to avoid deformation.

[0008] As an optimization, the plurality of diagonal bracing rods are arranged in a wave shape along the length direction of the support frame. The diagonal bracing rods arranged in this optimized wave shape can connect the first crossbeam and the diagonal bracing beam in different directions, thereby further improving the overall connection strength of the support frame.

[0009] As an optimization, the cabin comprises a ring beam frame and a base frame arranged vertically, as well as a wall structure. The wall structure comprises a wall frame detachably connected to the ring beam frame and base frame, and inner and outer panels mounted on the wall frame. This optimization solution makes the wall structure detachable, making assembly and disassembly more convenient and facilitating the subsequent entry of small equipment into the cabin.

[0010] As an optimization, the inner side plate is a thermal insulation plate. This optimization solution enhances the thermal insulation performance of the prefabricated cabin.

[0011] As an optimization, the outer plate is a steel plate or a metal carved plate. This optimization solution can improve the external strength of the wall and has the effect of sealing and waterproofing.

[0012] As an optimization, the wall frame includes columns supported at the four corners. The upper and lower ends of the columns are fixedly connected to the ring beam and base frame, respectively. Multiple support columns are arranged between adjacent columns. The upper and lower ends of these support columns are connected to the ring beam and base frame via angle brackets. Transverse reinforcement rods are connected between the support columns and the columns, as well as between adjacent support columns, via angle brackets. This optimization solution, through the fixed connection of the columns to the ring beam and base frame, creates a stable three-dimensional frame structure for the cabin, enhancing its overall structural strength. The support columns and reinforcement rods are connected to the three-dimensional frame structure via angle brackets, making assembly and disassembly easy.

[0013] As an optimization, the chassis includes a rectangular outer frame within which multiple channel steel beams are arranged lengthwise. The channel steel beams extend widthwise, with multiple cross beams fixedly connected between adjacent channel steel beams. At least three cross beams supporting the switchgear are arranged at the switchgear installation location, and the switchgear base and cross beams are fixedly connected. This optimization solution uses cross beams to enhance the structural strength of the rectangular outer frame while facilitating switchgear installation.

[0014] As an optimization, a floor is fixed to the chassis, with holes for primary and secondary cables and a pre-installed hole for the switchgear. Insulating rubber mats are also applied to the floor. This optimization solution facilitates the insertion of external cables into the cabin through the holes for primary and secondary cables, and facilitates the secure connection of the switchgear to the underlying channel steel beams through the pre-installed hole for the switchgear. The insulating rubber mats provide insulation and enhance safety.

[0015] As an optimization, the base frame and the supporting frame are both provided with lifting parts for hoisting. This optimization solution facilitates the hoisting and transportation of the cabin body and cabin roof.

[0016] The beneficial effects of the present invention are as follows: the prefabricated cabin is assembled as a whole using an assembled structure, which is easy to install as a whole, has high structural strength, and is convenient for transportation and movement. The cabin body is assembled by a base frame, a ring beam frame and a middle wall body. The support columns and reinforcing rods of the wall body are connected by angle brackets, which are easy to assemble and disassemble, and are convenient for the entry of small equipment into the cabin in the later stage. The cabin roof is assembled by a support frame and a top plate and can be detachably installed on the cabin body, which is convenient for the entry of large equipment into the cabin in the later stage. The overall structure of the prefabricated cabin is compact and strict, with higher strength. The switch cabinet is installed on the channel steel beam in the prefabricated cabin, which is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

The channel steel beams extend along the width direction. A plurality of cross beams 213 are fixedly connected between adjacent channel steel beams 212. At least three cross beams 213 supporting the switch cabinet are arranged at the installation position of the switch cabinet 1, and the base of the switch cabinet 2 is fixedly connected to the cross beams 213.

[0027] The rectangular outer frame 211 of this embodiment is formed by welding four square tubes together. The ends of the channel steel beams 212 are welded to the rectangular outer frame 211. The crossarm beams 213 are also made of channel steel, and their ends are welded to adjacent channel steel beams 212. The switchgear 2 of this embodiment is supported by three crossarm beams 213, which are welded to the front, middle, and rear ends of the bottom of the switchgear 2, respectively, to ensure the stability of the switchgear.

[0028] A floor is fixed to the base frame 21. The floor is provided with a primary cable hole 214, a secondary cable hole 215, and holes reserved for switchgear installation. The floor is also covered with an insulating rubber mat. In this embodiment, the floor is constructed of 3mm thick steel plates in sections. When the switchgear 2 is installed, corresponding holes reserved for switchgear installation are opened in the floor according to the installation location for welding and securing the switchgear. Primary and secondary cable holes are also opened on the steel plates at corresponding locations, corresponding to the holes in the bottom of the switchgear, for the incoming and outgoing cables of the equipment.

[0029] The ring beam 22 is a rectangular frame formed by welding four C-shaped steel bars. The ring beam 22 and the base frame 21 are combined with four walls 23 to form the cabin, and a hatch 25 is installed on one of the walls 23. The wall 23 includes a wall frame that is detachably fixed to the ring beam 22 and the base frame 21, and an inner panel 236 and an outer panel 235 mounted on the wall frame.

[0030] Specifically, the wall frame includes columns 231 supported at the four corners, and the upper and lower ends of the columns 231 are respectively fixed to the ring beam frame 22 and the base frame 21. In this embodiment, the four corners of the ring beam frame 22 and the base frame 21 are connected by four columns 231. The columns 231 are 90° angle columns bent from 4 mm thick steel plates. The upper and lower ends of the columns 231 are welded with column connecting seats, and the columns are fixedly connected to the ring beam frame and the base frame through bolts through the column connecting seats.

[0031] Multiple support columns 232 are arranged between adjacent columns 231. The upper and lower ends of the support columns 232 are connected to the ring beam frame 22 and the base frame 21 via angle brackets 234. Transverse reinforcement rods 233 are connected between the support columns 232 and the columns 231, as well as between adjacent support columns 232, via angle brackets 234. In this embodiment, the support columns 232 are angle steels, and the reinforcement rods 233 are flat steels. Connection holes for connecting to the support columns are provided at the bottom of the ring beam frame 22 and the top of the base frame. The support columns are bolted to the base frame and the ring beam frame using angle brackets as connectors.

[0032] The outer panel 235 is connected to the wall frame with self-tapping screws. The outer panel 235 is a steel plate or a metal carved plate. In this embodiment, the lower end of the outer panel 235 is flush with the top of the base frame 21, and the upper end of the outer panel 235 is flush with the top of the ring beam frame 22, thereby ensuring the sealing of the outer panel to the cabin.

[0033] The inner plate 236 is an insulation board, the upper and lower ends of which are fixed by aluminum channels, and the aluminum channels are screwed to the wall frame. The upper and lower ends of the insulation board in this embodiment are respectively flush with the bottom of the ring beam and the top of the base frame, thereby facilitating the demolition of the entire wall.

[0034] The cabin roof 3 comprises multiple support frames 31 and a top plate 32. The multiple support frames 31 are arranged along the length of the cabin hull 2 ​​and are removably secured to the top of the cabin hull 2. Adjacent support frames 31 are secured together by multiple connecting beams 314. The support frames 31 form a triangular frame structure, and the top plate 32 is laid on the two inclined surfaces of the triangular frame structure. In this embodiment, the cabin roof 3 includes at least two support frames 31, and the two support frames 31 are located on opposite sides of the cabin hull 2 ​​walls 23. After the cabin roof 3 is assembled, suitable triangular transparent window panels can be installed within the triangular frames of the two support frames 31 to increase lighting while also sealing the cabin roof.

[0035] Specifically, the support frame 31 includes a first crossbeam 311 and two diagonal bracing beams 312.
