Description

Technical Field

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

[0002] In power grid engineering, the use of prefabricated modules is becoming increasingly widespread. Taking GIS (Gas Insulated Switchgear) as an example, when configuring GIS equipment, prefabricated modules are required according to the design requirements of some projects. Multiple modules of the prefabricated module are prefabricated in a factory and then transported to the construction site by road or other means, where they are finally assembled. However, with continuous technological advancements, the prefabricated modules used in substations need to integrate compartments with different functions, leading to a significant increase in the number and size of the modules and consequently, a substantial rise in logistics costs. Utility Model Content

[0003] The main purpose of this utility model is to propose a prefabricated module and substation, which aims to reduce the overall logistics cost of transporting prefabricated modules with multiple compartments from the factory to the construction site.

[0004] To achieve the above objectives, this utility model proposes a prefabricated cabin, including walls, functional cabins, and a cabin roof. The functional cabin has a length direction and a width direction, and the functional cabin includes a bottom frame, multiple vertical frames, and multiple longitudinal beams. The vertical frame includes a crossbeam and two columns. Along the width direction, the two ends of the bottom frame are respectively connected to the bottom ends of the two columns, and the two ends of the crossbeam are respectively connected to the top ends of the two columns. Along the length direction, a plurality of the vertical frames are installed parallel to each other on the bottom frame, and a longitudinal beam is installed between adjacent vertical frames; The number of functional compartments is two, and the two functional compartments are spaced apart along the width direction. The walls are installed on the opposite sides of the two functional compartments. The compartment roof is erected on the top of the two functional compartments, and the compartment roof and the two functional compartments enclose an equipment compartment.

[0005] In one embodiment, the bottom frame includes an outer frame and a reinforcing frame, the reinforcing frame being disposed inside the outer frame, and the reinforcing frame including multiple reinforcing rods distributed in a grid pattern.

[0006] In one embodiment, the bottom frame further includes a support plate, which is mounted on the top of the outer frame.

[0007] In one embodiment, the upright frame further includes diagonal bracing, which is inclined and its two ends are respectively connected to the crossbeam and the column.

[0008] In one embodiment, the wall includes a supporting frame, an outer side layer, and an inner side layer. The supporting frame is connected to the adjacent column. The outer side layer is disposed on the side of the supporting frame away from the equipment compartment, and the inner side layer is disposed on the side of the supporting frame facing the equipment compartment.

[0009] In one embodiment, the wall further includes a waterproof wall layer and a thermal insulation wall layer, wherein the waterproof wall layer is disposed between the outer surface layer and the supporting frame, and the thermal insulation wall layer is disposed between the supporting frame and the inner surface layer.

[0010] In one embodiment, the cabin roof includes a top cover and two support frames, each of which is installed on the top of one of the functional cabins. Each support frame includes a base frame and a vertical frame. The base frame is connected to the crossbeam and the longitudinal beam. The bottom end of the vertical frame is connected to the base frame, and the top end of the vertical frame is connected to the top cover.

[0011] In one embodiment, the top cover includes a truss and a roof, with the bottom end of the truss connected to the top end of the support frame; The roof is erected on the truss, and the roof includes a roof frame and a roof surface layer. The roof frame is installed on the truss, and the roof surface layer is installed on the side of the roof frame away from the equipment compartment.

[0012] In one embodiment, the roof further includes a waterproof roof layer and a thermal insulation roof layer, wherein the waterproof roof layer is installed between the roof surface layer and the roof frame, and the thermal insulation roof layer is installed on the side of the roof frame facing the equipment compartment.

[0013] This utility model also proposes a substation, including a prefabricated compartment as described in any of the above embodiments, the substation further including a gas-insulated switchgear, the gas-insulated switchgear being installed in the compartment.

[0014] According to the technical solution of this utility model, the prefabricated cabin includes walls, functional cabins, and a roof. The functional cabin has a length direction and a width direction, and includes a base frame, multiple vertical frames, and multiple longitudinal beams. Each vertical frame includes a horizontal beam and two columns. Along the width direction, both ends of the base frame are connected to the bottom ends of the two columns, and both ends of the horizontal beam are connected to the top ends of the two columns. Along the length direction, multiple vertical frames are installed parallel and spaced apart on the base frame, and longitudinal beams are installed between adjacent vertical frames. There are two functional cabins, spaced apart along the width direction. Walls are installed on opposite sides of the two functional cabins, and the roof is erected on top of the two functional cabins, forming an equipment cabin with the roof and the two functional cabins. This design allows the columns, base frame, longitudinal beams, and transverse beams to enclose and form functional compartments. Two functional compartments, together with the roof, can enclose and form an equipment compartment. Therefore, the prefabricated module in this design has two functional compartments and one equipment compartment, resulting in multiple compartments to meet the design requirements of the substation. Furthermore, traditional prefabricated modules require the equipment compartment to be prefabricated in a factory. Since the equipment compartment is large and occupies significant transport space, multiple transport vehicles are needed. In contrast, the equipment compartment in this design is not prefabricated in a factory but is formed by the functional compartments and the roof. Therefore, the equipment compartment does not occupy transport space during transport, allowing two functional compartments to be placed in a single transport vehicle. This reduces the number of transport vehicles required and consequently lowers logistics costs. Attached Figure Description

[0022] In the field of power grid engineering, the application scenarios of prefabricated modules are becoming increasingly widespread. Taking GIS (Gas Insulated Switchgear), a key power equipment, as an example, prefabricated modules are typically required for GIS equipment during the planning and construction of power grid projects, based on the unique design requirements of different projects. Prefabricated modules have significant advantages in industrialized production, as the multiple functional modules they contain are standardized and prefabricated in a factory environment. After prefabrication, these modules are transported to the project construction site in batches via methods such as road transport. Upon arrival at the site, construction personnel precisely assemble these modules according to the pre-designed plan, ultimately forming a fully functional and structurally stable prefabricated module, providing reliable physical space protection for the stable operation of GIS equipment.

[0023] However, according to the applicant's observations and research, with the continuous advancement and improvement of technology, the design concepts and functional requirements of prefabricated modules used in substations have undergone significant changes. Today, substations place higher demands on the functional integration of prefabricated modules, requiring the integration of multiple compartments with different functions within a single prefabricated module to meet the diverse operational needs of the substation. This trend towards functional integration directly leads to an increase in the number of prefabricated module modules, and a corresponding increase in the volume of each module. This dual increase in the number and volume of modules significantly increases the logistical resources required during transportation, resulting in a noticeable rise in logistics costs.

[0024] In view of this, the present invention proposes a prefabricated cabin to reduce the logistics costs incurred during transportation.

[0025] Please see Figures 1 to 3 In one embodiment of this utility model, the prefabricated cabin 100 includes a wall 3, a functional cabin 1, and a cabin roof 2. The functional cabin 1 has a length direction X and a width direction Y, and includes a bottom frame 11, multiple vertical frames 12, and multiple longitudinal beams 13. Each vertical frame 12 includes a horizontal beam 121 and two columns 122. Along the width direction Y, both ends of the bottom frame 11 are connected to the bottom ends of the two columns 122, and both ends of the horizontal beam 121 are connected to the top ends of the two columns 122. Along the length direction X, multiple vertical frames 12 are installed parallel to each other on the bottom frame 11, and longitudinal beams 13 are installed between adjacent vertical frames 12. There are two functional cabins 1, spaced apart along the width direction Y. A wall is installed on the opposite side of each functional cabin 1. The cabin roof 2 is erected on top of the two functional cabins 1, and the cabin roof 2 and the two functional cabins 1 enclose an equipment cabin 4.

[0026] Please refer to the length direction X. Figure 2 The direction indicated by the middle arrow X; for the width direction Y, please refer to [reference needed]. Figure 1The direction indicated by the middle arrow Y. In this embodiment, the columns 122, crossbeams 121, and longitudinal beams 13 are all made of either I-beams or H-beams. The connection between the columns 122 and the base frame 11, between the columns 122 and the crossbeams 121, and between the functional compartment 1 and the roof 2 includes either welding or bolting. The functional compartment 1 is prefabricated in the factory, so the connection between the columns 122, the base frame 11, and the crossbeams 121 is completed in the factory. Simultaneously, the walls are installed on the functional compartment 1; specifically, the walls are bolted or welded to the columns 122. The connection between the functional compartment 1 and the roof 2 needs to be completed on-site. Specifically, after the functional compartment 1 with its walls installed is transported to the site, it is lifted by a crane to the construction site. After positioning, the functional compartment 1 is installed on the foundation. Subsequently, the roof 2 arrives on site and is lifted by a crane to the top of the functional compartment 1. After positioning, the roof 2 is connected to the functional compartment 1.

[0027] It should also be noted that, in this embodiment, the bottom frame 11, the vertical frame 12, and the longitudinal beam 13 in the functional compartment 1 enclose a functional cavity, which can be used as a maintenance passage, a control room, or a fire escape. The specific functional settings can be determined according to design requirements. Specifically, if chosen as a maintenance passage, the distance between adjacent vertical columns 122 along the width direction Y must be no less than 1.2m, and the distance between vertical frames 12 can be set between 1.5m and 2m.

[0028] Through the technical solution of this embodiment, the columns 122, the base frame 11, the longitudinal beams 13, and the transverse beams 121 can be enclosed to form a functional compartment 14, and the two functional compartments 1 and the top 2 can be enclosed to form an equipment compartment 4. Thus, the prefabricated compartment 100 in this solution has two functional compartments 14 and one equipment compartment 4, thereby enabling the prefabricated compartment 100 in this embodiment to have multiple compartments to meet the design requirements of the substation. At the same time, the equipment compartment 4 in the traditional prefabricated compartment 100 needs to be prefabricated in the factory. The equipment compartment 4 is large in volume and occupies a large transportation space, so multiple transport vehicles are needed to transport the traditional prefabricated compartment 100. Since the equipment compartment 4 in this embodiment is not prefabricated in the factory, but is formed by the functional compartments 1 and the top 2, the equipment compartment 4 does not occupy transportation space during transportation. Thus, compared to traditional prefabricated cabins, under the premise that the cargo volume of the transport vehicle remains unchanged, the two functional cabins 1 in this embodiment can be placed in one transport vehicle at the same time. This means that the transportation process of the prefabricated cabin 100 provided in this embodiment only requires two transport vehicles (one for transporting the two functional cabins 1 and the other for transporting the cabin roof 2), which helps to reduce the number of transport vehicles and thus reduce logistics costs.

[0029] Furthermore, compared to the traditional prefabricated cabin 100, the prefabricated cabin 100 provided in this embodiment does not have an integral frame at the bottom, that is, the frame at the bottom of the equipment cabin 4 is eliminated. The foundation of the gas-insulated switchgear 200 installation part can be made of cast-in-place concrete, thereby reducing the amount of steel used in the prefabricated cabin 100 provided in this embodiment, which is beneficial to controlling the material cost of the prefabricated cabin 100.

[0030] In one embodiment of this utility model, the base frame 11 includes an outer frame and a reinforcing frame. The reinforcing frame is disposed inside the outer frame and includes multiple reinforcing rods arranged in a grid pattern. Specifically, the outer frame is generally rectangular and is welded from I-beams or H-beams. The reinforcing frame is welded inside the outer frame and has a grid structure to provide support. The reinforcing rods are selected from either I-beams or H-beams. When connected to the column 122, the bottom end of the column 122 is connected to the top surface of the outer frame to fully utilize the load-bearing capacity of the I-beams or H-beams. Through this arrangement, the base frame 11 serves both as a load-bearing component capable of supporting the upper load and as a platform for placing equipment or for workers to walk on, thus meeting the usage requirements of the prefabricated cabin 100.

[0031] In one embodiment of this utility model, the bottom frame 11 further includes a support plate, which is installed on the top of the outer frame. The support plate includes one of a patterned steel plate and an anti-slip steel mesh, and is laid on the top of the reinforcing frame to provide a flat surface for workers to walk on or for installing equipment.

[0032] Please see Figure 3 In one embodiment of this utility model, the frame 12 further includes a diagonal brace 123, which is inclined and connected at both ends to the crossbeam 121 and the column 122, respectively. The diagonal brace 123 transforms the frame 12 from a rectangular structure into a stable triangular system, improving the functional cabin 1's resistance to lateral forces (such as wind and earthquakes) and reducing structural deformation. Furthermore, the diagonal brace 123 converts the horizontal force acting on the crossbeam 121 into an axial force on the diagonal brace 123, optimizing the path of torque transmission from the crossbeam 121 to the column 122.

[0033] In one embodiment of this utility model, the wall includes a supporting frame, an outer surface layer, and an inner surface layer. The supporting frame is connected to adjacent columns 122. The outer surface layer is located on the side of the supporting frame away from the equipment compartment 4, and the inner surface layer is located on the side of the supporting frame facing the equipment compartment 4. The supporting frame is welded or bolted to the columns 122. The supporting frame is formed by welding channel steel or square steel and can bear the main vertical load (self-weight) and horizontal load (such as wind load and seismic action) of the wall, effectively transferring these forces to the connected columns 122. The supporting frame facilitates the installation of the wall onto the columns 122, improving the convenience of wall installation, and also provides sufficient rigidity to prevent excessive deformation of the wall due to external loads. Furthermore, the inner and outer surface layers include either color steel plates or profiled steel plates to provide a certain degree of protection.

[0034] Furthermore, in one embodiment of this utility model, the wall further includes a waterproof layer and a thermal insulation layer. The waterproof layer is disposed between the outer surface layer and the supporting frame, and the thermal insulation layer is disposed between the supporting frame and the inner surface layer. The waterproof layer includes either waterproof tarpaulin or asphalt felt, and the thermal insulation layer includes either rock wool board or polyurethane foam. This arrangement enables the waterproof layer to resist external wind and rain erosion of the supporting frame and insulation layer, and keeps the thermal insulation layer in a relatively dry and temperature-stable indoor environment, preventing the insulation layer from reducing its effectiveness due to moisture absorption.

[0035] Please see Figure 1 and Figure 4 In one embodiment of this utility model, the cabin roof 2 includes a top cover 21 and two support frames 22. Each support frame 22 is installed on the top of a functional cabin 1. The support frame 22 includes a base frame 221 and a vertical frame 222. The base frame 221 is connected to the crossbeam 121 and the longitudinal beam 13. The bottom end of the vertical frame 222 is connected to the base frame 221, and the top end of the vertical frame 222 is connected to the top cover 21. In this embodiment, the vertical frame 222 and the base frame 221 are formed by welding I-beams or H-beams. The base frame 221 is connected to the crossbeam 121 and the longitudinal beam 13 by bolts or welding. By adjusting the height of the vertical frame 222, the elevation of the top cover 21 can be changed, thereby flexibly adjusting the height of the equipment cabin 4. The vertical frame 222 and the base frame 221 serve as transition structures for the top cover 21, which can evenly transfer the load of the top cover 21 to the functional cabin 1, thus improving the stability of the installation of the top cover 21. In addition, the support frame 222 forms an equipment layer space between the top cover 21 and the functional compartment 14, which facilitates the neat arrangement of pipelines, installation of air conditioners, fans and other equipment, and realizes functional integration.

[0036] Please see Figure 4In one embodiment of this utility model, the roof 21 includes a truss 211 and a roof 212. The bottom end of the truss 211 is connected to the top end of the support frame 222. The roof 212 is erected on the truss 211 and includes a roof frame and a roof surface layer. The roof frame is installed on the truss 211, and the roof surface layer is installed on the side of the roof frame away from the equipment compartment 4. The truss 211, as the main load-bearing structure of the roof 212, can efficiently transfer the load of the roof 212 to the support frame 22 below. It can meet the requirements of large span settings and has geometric stability, effectively resisting loads such as wind and snow. The roof frame, as the frame of the roof 212, adopts a purlin structure or uses multiple parallel steel sections directly installed on the top of the truss 211 along the length direction X. The roof surface layer is made of either color steel plate or profiled steel plate, which is directly laid on the top surface of the roof frame. By setting up a layered force transmission system of top cover surface layer, top cover frame and truss 211 in top cover 21, the external load on top cover surface layer can be transmitted downward in sequence, thereby improving the stability of top cover 21.

[0037] In one embodiment of this utility model, the roof 212 further includes a waterproof layer and a thermal insulation layer. The waterproof layer is installed between the roof surface layer and the roof frame, and the thermal insulation layer is installed on the side of the roof frame facing the equipment compartment 4. The waterproof layer includes either a waterproof curtain or asphalt felt, and the thermal insulation layer includes either rock wool board or polyurethane foam. This arrangement allows the waterproof layer to resist external wind and rain erosion of the supporting frame and the thermal insulation layer, keeping the thermal insulation layer in a relatively dry and temperature-stable indoor environment, thus preventing the thermal insulation layer from reducing its effectiveness due to moisture absorption.

[0038] This utility model also proposes a substation, which includes a prefabricated module 100. The specific structure of the prefabricated module 100 is as described in the above embodiments. Since this substation adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. Please refer to [link to relevant documentation]. Figure 1 The substation also includes a gas-insulated switchgear 200, which is installed in an equipment compartment. The bottom of the gas-insulated switchgear is fixed to a foundation, which is a cast-in-place concrete foundation.
