[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the mounting plate 3 is located between the side plates 7, and heat dissipation fins are fixedly connected to the side plates 7 and the side adjacent to the mounting plate 3, and heat dissipation holes are opened through the surface of the side plates 7.

[0028] In this embodiment, as Figure 3 and Figure 7 As shown, the side plate 7 and the side plate reinforcing groove 103 are rotatably connected by a hinge. The side plate reinforcing grooves 103 on both sides have different heights, with one side being higher. At the end of the side plate reinforcing groove 103 with the higher height, the bottom of the side plate 7 connected to it is shorter than the bottom of the side plate 7 at the other end. The tops of the two side plates 7 are at the same horizontal height, and the side plates 7 are provided with T-shaped strips on the same side. The strips are through and can be inserted into the corresponding slots at both ends of the back plate 10. At the same time, the side plates 7 can be folded on the surface of the base 1 by the hinge, and the side plate 7 located at the end of the side plate reinforcing groove 103 with the higher height is folded and attached to the top of the other side plate 7.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the height of the door panel 8 is consistent with the straight-line distance between the front kick plate 101 and the top seat 2, and the door panel 8 is hinged to form a 270° angle at one end of its corresponding side panel 7.

[0030] In this embodiment, as Figure 3 and Figure 7 As shown, the side plate reinforcement groove 103 has a slot for inserting the reinforcement block 9 directly below it, and the reinforcement block 9 has a threaded through hole on the side adjacent to the front kick plate 101. The front kick plate 101 and the side plate 7 also have threaded through holes of the same specification at corresponding positions on their surfaces. The reinforcement block 9 is connected to the side plate 7 and the side plate reinforcement groove 103 by means of quick-release bolts and threaded through holes.

[0031] In this embodiment, as Figure 3 and Figure 4As shown, the top seat 2 is trapezoidal in shape, narrower at the top and wider at the bottom.

At the same time, both the strip-shaped protrusion and one side of the rear kick plate 102 are provided with threaded through holes. The threaded through holes are connected by quick-release bolts.

[0032] In this embodiment, as Figure 5 and Figure 6 As shown, the electrical component fixing part 4 consists of an L-shaped base plate, a fixed side plate, and an adjusting plate that is slidably connected to the surface of the L-shaped base plate by a spring. A wire harness sleeve is fixedly connected to the bottom of the L-shaped base plate, and grid-shaped through holes are opened through the surfaces of the fixed side plate and the adjusting plate.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this modular, quick-assembly box-type substation, which is easy to disassemble, operates as follows:

[0034] Firstly, compared to traditional integrated structures, this prefabricated substation allows for modular splicing and assembly. During initial installation, the base 1 is placed in a suitable position. Since the top two ends of the base 1 are connected to the side plates 7 via hinges, the quick-release bolts on the surface of the side plates 7 are removed before installation. After the side plates 7 are unfolded, the bottom reinforcing blocks 9, no longer secured by the quick-release bolts, automatically slide out under gravity. The side plate reinforcing groove 103 has an insertion slot directly below the corresponding reinforcing block 9, allowing the reinforcing block 9 to smoothly insert into it. The connection between the side plate reinforcing groove 103 and the reinforcing block 9 provides additional reinforcement support for the side plates 7, enhancing the stability of the entire structure. The removed quick-release bolts are then threaded into the corresponding through holes on the surface of the front kick plate 101 until the bolt shaft... After the head passes through the front kick plate 101 and another slot of the side plate reinforcement groove 103, it is threaded to the slot of the reinforcement block 9, thus completing the vertical installation of the side plate 7. The front kick plate 101 not only plays a fixed connection role during installation, but also provides protection for the front of the base 1. The other side plate 7 is unfolded and fixed in the same way. The top seat 2 and the unfolded back plate 10 are inserted from top to bottom from the corresponding positions of the two side plates 7. The side plates 7 are provided with through T-shaped strips on the same side. The back plate 10 has slots at the corresponding positions at both ends. The two are interlocked to complete the initial installation. This structure makes the installation of the back plate 10 more stable, and at the same time ensures good sealing between the back plate 10 and the side plate 7, which helps to protect the external environment from the influence of the substation. During insertion, the bottom strip-shaped protrusion engages with the corresponding slot on the surface of the rear kick plate 102, further positioning the back plate 10. The rear kick plate 102, similar to the front kick plate 101, serves a protective and auxiliary installation function. Finally, quick-release bolts and threaded through holes are used for further reinforcement to ensure the back plate 10 is securely installed. The mounting plate 3 is pushed inwards from the outside using the corresponding sliding groove on the bottom surface of the base 1. For small electrical components, such as relays and fuses, the electrical component fixing piece 4 is used for installation. The electrical component fixing piece 4 consists of an L-shaped base plate, a fixed side plate, and an adjusting plate that is slidably connected to the surface of the L-shaped base plate via a spring. Both the fixed side plate and the adjusting plate have through-holes in a grid pattern. While fixing the electrical components, these through-holes allow for easy access to the electrical components. The components provide excellent heat dissipation channels, allowing the heat generated by the electrical components to be quickly dissipated into the surrounding air, preventing overheating from affecting the performance and lifespan of the electrical components. The L-shaped base plate has a cable routing port on its surface and a cable bundle sleeve fixedly connected below, which facilitates internal cable routing. The adjusting plate, through the elastic compression of the spring, can adjust the distance between itself and the fixed side plate according to the size and specifications of small electrical components, achieving a good locking and fixing, and adapting to the installation needs of various sizes of small electrical components. For medium-sized electrical components, they can be mounted on the bracket plate 5, which is hinged and flipped 90° on the surface of the mounting plate 3. When the bracket plate 5 is unfolded, the structure of the mounting plate 3 corresponding to the bottom of the bracket plate 5 for inserting the support frame 6 is unfolded. The support frame 6 is then horizontally flipped 90° and attached to the bottom of the bracket plate 5.The support structure of the mounting plate 5 provides stability for the installation of medium-sized electrical components, while large electrical components are placed in the space between the bottom of the mounting plate 5 and the base 1, making full use of the internal space layout of the prefabricated substation. Through holes for cable routing are provided at corresponding positions on the mounting plate 3 and the back plate 10, which helps to connect the internal cables of the substation to the external ground wire, ensuring the integrity and safety of the electrical connection. One side of the side plate 7 is connected to the door plate 8 by a 270° hinge. This large-angle hinge allows the door plate 8 to open and close flexibly, which is more convenient than that of an integrated prefabricated substation. Traditional modular substations often suffer from large size and fixed shape, occupying significant space during transportation and storage, and are easily damaged by collisions. This prefabricated substation addresses these issues by featuring foldable and rotatable side panels 7 and door panels 8. These foldable panels reduce the overall volume during transport and storage, facilitating handling and storage, lowering transportation costs and storage difficulty, and effectively reducing the risk of damage during transit. Furthermore, because it can be disassembled into multiple modules, it is easier to handle and transport compared to integrated prefabricated substations, reducing space occupation and transportation difficulty, and lowering transportation costs and risks. The substation's internal space can be flexibly divided according to the size of electrical components. Small electrical components can be installed using the component mounting bracket 4, whose adjustable plate can adjust the spacing to achieve locking according to the component size. Medium-sized electrical components can be mounted on the frame plate 5, which is hinged and flipped by the mounting plate 3, and supported by the support frame 6. Large electrical components can be placed in the space between the bottom of the frame plate 5 and the base 1. This design makes full use of the internal space of the box-type substation, improving space utilization. After all electrical components are installed, the door panel 8 can be unfolded to realize the enclosed structure of the box-type substation. The height of the door panel 8 is consistent with the straight-line distance between the front kick plate 101, the rear kick plate 102, and the top seat 2, ensuring the neat appearance and airtightness of the entire prefabricated substation after enclosure. During daily use, the heat dissipation fins on one side of the side panel 7 increase the heat dissipation area, enabling rapid conduction of internal heat to the outside. The heat dissipation holes on its surface further promote airflow, allowing hot air to escape through the holes, forming natural convection and effectively reducing the internal temperature. When the fan above operates, it accelerates the airflow inside the prefabricated substation, expelling hot air upwards from the heat dissipation vents at both ends, enhancing the heat dissipation effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
