Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an electrical prefabricated cabin. Background Technology

[0002] Prefabricated electrical modules are a technological solution that integrates electrical equipment, control equipment, and protection devices into one or more prefabricated modules. Through factory prefabrication and rapid on-site assembly, they significantly shorten the construction cycle of power systems and improve their reliability and safety. For example, according to one study, the construction cycle of substations using prefabricated electrical modules can be shortened by more than 40%, while reducing the need for on-site construction personnel and lowering safety risks. The design of prefabricated electrical modules follows strict safety standards to ensure stable operation in extreme environments. However, existing prefabricated electrical modules are typically welded from high-strength steel. This steel structure construction results in a large module weight, high transportation costs, difficult installation, and high hoisting risks. Furthermore, steel prefabricated modules have poor corrosion resistance, and the anti-corrosion coating process is complex. If bumps occur during transportation and installation, even after anti-corrosion treatment, their durability cannot be guaranteed. Especially in desert and coastal areas, their anti-corrosion performance often fails to meet the design service life. Utility Model Content

[0047] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0048] like Figures 1 to 10 As shown, an embodiment of this utility model provides an electrical prefabricated cabin, comprising:

[0049] A hull frame that is set on the ground and fixedly connected to the ground by multiple first fixing components;

[0050] Four first columns 11 are installed on the bottom frame, and each first column 11 is fixedly connected to the bottom frame through multiple first connectors 31.

[0053] The bottom frame, top frame, and first column 11 are all made of basalt fiber composite material.

[0054] In this embodiment, the basalt fiber composite material is a composite material produced through a specific process, using basalt fiber as the main material, synthetic resin as the matrix material, and adding UV stabilizers, flame retardants, fillers, and other additives. The basalt fiber composite material features low density, high strength, good corrosion resistance, good heat resistance, good fire resistance, durability, good insulation, and strong design flexibility. It can withstand the effects of environmental conditions such as rain, snow, hail, wind, sandstorms, salt spray, lightning, electromagnetic interference, and solar radiation. The electrical prefabricated cabin of this invention provides functions such as ventilation, heat dissipation, dust prevention, shielding, grounding, and earthquake resistance. It utilizes four first columns 11, first connectors 31, and second connectors 32 to connect the bottom frame and top frame of the cabin, forming an overall electrical prefabricated cabin frame. Then, double-layer fibrous composite panels 2 are applied to the four sides (around the four first columns 11) and top (on the top frame) of the overall electrical prefabricated cabin frame, and are fixed to the overall electrical prefabricated cabin frame with screws, thus forming... A complete prefabricated electrical cabin structure; the prefabricated electrical cabin of this utility model reduces the weight of the cabin and improves its corrosion resistance by using basalt fiber composite material for the cabin bottom frame, cabin top frame and first column 11; at the same time, because basalt fiber composite material is lightweight, it generates less seismic force during earthquakes, about one-third that of steel structure prefabricated cabins, so the prefabricated cabin made of this material also has good seismic performance; the design of the first connector 31 and the second connector 32 avoids welding when connecting the cabin bottom frame, cabin top frame and first column 11, solving the problem that basalt fiber composite materials cannot be welded together to form a frame structure; at the same time, the design of the connectors enables rapid assembly of the cabin bottom frame, cabin top frame and first column 11; and this connection method design avoids welding, so that the prefabricated electrical cabin can be used in a variety of scenarios, such as scenarios where open flames are not allowed, expanding the application range of prefabricated cabins, especially in desert and coastal areas where it has greater advantages.

[0055] In an optional embodiment of this utility model, the hull frame includes:

[0060] In an optional embodiment of this utility model, the cabin roof frame includes:

[0061] The first cabin roof frame beam 51 is set on two adjacent first columns 11 and the second cabin roof frame beam 52 is set on two other adjacent first columns 11 opposite to the first cabin roof frame beam 51. The first cabin roof frame beam 51 and the second cabin roof frame beam 52 are both connected to the first column 11 through the first connector 31.

[0062] Multiple top frame beam assemblies are disposed between the first top frame beam 51 and the second top frame beam 52. Both ends of the top frame beam assemblies are connected to two adjacent first columns 11 via second connectors 32.

[0063] The top frame beam assembly includes:

[0064] Third compartment top frame beam 53 and fourth compartment top frame beam 54;

[0065] The first end of the third compartment top frame beam 53 and the first end of the fourth compartment top frame beam 54 are connected at a first preset angle by a sleeve connector 55; the second end of the third compartment top frame beam 53 and the second end of the fourth compartment top frame beam 54 are both connected to the first column 11 by a second connector 32.

[0066] Both the first connector 31 and the second connector 32 have an "L" shaped structure. The included angle between two adjacent sides of the first connector 31 is a first preset value, and the included angle between two adjacent sides of the second connector 32 is a second preset value.

[0067] In a preferred embodiment, the roof frame further includes:

[0068] A fifth top frame beam 56 is disposed between two adjacent top frame beam assemblies, and the two ends of the fifth top frame beam 56 are connected to the two adjacent top frame beam assemblies through a first connector 31.

[0069] The sixth compartment top frame beam 57 is located between two adjacent third compartment top frame beams 53.

[0070] In this embodiment, the sleeve connector 55 is a square structure with a first preset angle. Both ends of the sleeve connector 55 are respectively provided with connection holes of the same size as the first ends of the third cabin roof frame beam 53 and the fourth cabin roof frame beam 54. In use, the first ends of the third cabin roof frame beam 53 and the fourth cabin roof frame beam 54 are respectively inserted into the connection holes at both ends of the sleeve connector 55, thereby achieving a connection at the first preset angle through the sleeve connector 55. The first preset angle can be set according to requirements. In a preferred embodiment, the first preset angle is 170 degrees to 175 degrees. The first preset angle connection design of the third cabin roof frame beam 53 and the fourth cabin roof frame beam 54 allows the double-layer fibrous composite board 2 to form a bidirectional drainage structure on the cabin roof when laid on the roof frame, with a drainage slope ranging from 5% to 10%. Multiple top frame crossbeam assemblies can be provided according to the number of second columns 12. Each top frame crossbeam assembly can be connected to the fifth cabin roof frame beam 56.

[0071] In this embodiment, the included angle between two adjacent sides of the first connector 31 and the included angle between two adjacent sides of the second connector 32 can be set according to connection requirements. For example, since the first column 11 and the bottom frame are both vertically aligned, the included angle between the first column 11 and the bottom frame is 90 degrees, so the included angle between the two adjacent sides of the first connector 31 can be set to 90 degrees. Correspondingly, since the top frame has a certain slope, the included angle between the top frame and the first column 11 ranges from 95 degrees to 100 degrees. Therefore, the included angle between the top frame and the first column 32 can be set according to the connection requirements. The included angle between the columns 11 is used to set the included angle value of the two adjacent sides of the second connector 32; in this embodiment, the first connector 31 and the second connector 32 have the same structure and the same usage process, the only difference being the included angle; the specific usage of the first connector 31 is explained below using the first connector 31 as an example: First, it should be noted that the two adjacent sides of the first connector 31 are provided with connecting holes for connecting the first bolt 34, and the bottom frame, top frame and the first column 11 are also provided with corresponding connecting holes; when the first connector 31 is used It can be used individually or simultaneously by placing two first connectors 31 opposite each other on both sides of the column or frame to be connected. When used individually, the first bolt 34 can be directly passed through the connecting hole on the first connector 31 and the connecting hole of the column to be fixed, and then the first connector 31 can be directly fixed to the column. When used in pairs opposite each other, taking the connection between the first column 11 and the bottom frame as an example, the two first connectors 31 can be placed opposite each other on both sides of the first column 11, and then the first bolt can be passed through one side of the two first connectors 31 and the connecting hole of the column to be fixed. The first column 11 between the two connecting pieces 31 is fixedly connected to one side of the two first connecting pieces 31, and then the other side of the first connecting piece 31 is connected to the bottom frame by passing a first bolt through it, thereby fixing the first column 11 to the bottom frame. In this embodiment, the design of the first connecting piece 31 and the second connecting piece 32 enables the rapid assembly of the bottom frame, the top frame and the first column 11. At the same time, this connection method design can avoid welding, so that the electrical prefabricated cabin can be used in a variety of scenarios.
