Description

Technical Field

[0001] This utility model relates to the field of substation technology, specifically a prefabricated substation. Background Technology

[0002] A prefabricated substation is a type of substation that organically combines high-voltage power reception, transformer voltage reduction, and low-voltage power distribution functions, all housed within a fully enclosed, movable steel structure enclosure. It boasts a series of advantages, including strong integration, short power transmission cycle, strong environmental adaptability, convenient installation, safe and reliable operation, and low investment with quick returns. With the accelerating modernization of municipal construction, prefabricated substations have been widely used in public power distribution during urban power grid construction and renovation, gradually replacing traditional civil engineering power distribution rooms and becoming a new type of complete power distribution device.

[0003] Currently, prefabricated substations are generally large in size due to their structural design, which directly leads to an increase in the size of the supporting doors. During substation assembly, the doors and the enclosure are connected and secured via hinges. However, existing hinge installation methods have significant drawbacks: they are not only cumbersome and difficult to operate, but the weight and maneuverability of the large doors further slow down the overall substation assembly process, significantly impacting assembly efficiency and causing numerous inconveniences in actual production and construction. Summary of the Invention

[0004] The purpose of this utility model is to provide a prefabricated substation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated substation, comprising a prefabricated box, wherein an installation cavity is provided inside the box, and a door is fixedly connected to the front and rear ends, as well as the left and right sides of the prefabricated box at opposite positions in the installation cavity via a hinge assembly. The hinge assembly includes a first connector and a second connector, the first connector and the second connector being fixedly installed on the outer wall surface of the box and the inner wall surface of the door, respectively. One end of the first connector and the second connector are engaged with each other and can rotate around the connection point between the first connector and the second connector.

[0006] Preferably, the first connector includes a first mounting plate, a connecting ring, and a connecting ball. The first mounting plate is fixedly connected to the outer wall surface of the housing by bolts. A connecting ring with a notch is fixedly connected to the middle of one end of the first mounting plate. Connecting balls are fixedly connected to the upper and lower ends of the connecting ring on the surface of the first mounting plate.

[0007] Preferably, the second connector includes a second mounting plate and a connecting block. The second mounting plate is fixedly connected to the inner wall surface of the door by bolts. A connecting block is fixedly connected to the middle of one end of the second mounting plate. A rotating hole adapted to the connecting ring is provided between the second mounting plate and the connecting block, and the inner wall of the rotating hole is rotatably connected to the outer wall of the connecting ring.

[0008] Preferably, the outer wall of the connecting block has an arc-shaped opening that communicates with the rotating hole, and the top and bottom of the connecting block have connecting positions for the connecting ball to engage and rotate.

[0009] Preferably, the door surface has heat dissipation vents at both the top and bottom.

[0010] Beneficial effects

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention effectively solves the problems of cumbersome and inefficient assembly of traditional box-type substation doors through an innovatively designed hinge assembly. The hinge assembly consists of a first connector and a second connector that interlock. The first connector is fixed to the outer wall of the box with bolts, and its notched connecting ring matches the rotating hole of the second connector. The connecting ball can precisely engage with the connecting position of the connecting block. This interlocking structure eliminates the need for complex alignment and tightening steps. Operators only need to interlock the first and second connectors to quickly complete the connection between the door and the box, significantly simplifying the installation process. Compared to traditional hinge installation methods, this not only reduces the professional skills required of operators but also avoids time wasted due to repeated adjustments when dealing with large and heavy doors, significantly accelerating the overall assembly progress of the substation and saving considerable time and labor costs in actual production and construction.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figure 1-3 This is a structural schematic diagram of a prefabricated substation according to a preferred embodiment of the present invention. In this embodiment, the prefabricated substation includes a housing 1, which is made of high-strength steel and has good structural stability and protective performance. The installation cavity 11 inside the housing 1 is spacious, allowing for the rational layout of various electrical equipment and ensuring the safety and orderliness of equipment operation. A door 3 is fixedly connected to the front and rear ends, as well as the left and right sides of the housing 1, at relative positions within the installation cavity 11, via a hinge assembly 2. The hinge assembly 2 includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 and the second connecting member 22 are respectively fixedly installed on the outer wall surface of the housing 1 and the inner wall surface of the door 3. One end of the first connecting member 21 and the second connecting member 22 are interlocked and rotate around the connection point between the first connecting member 21 and the second connecting member 22.

[0022] In this embodiment, when installing the door 3, the first connector 21 is first installed on the outer wall surface of the box body 1. The first connector 21 includes a first mounting plate 211, a connecting ring 212, and a connecting ball 213. The first mounting plate 211 is tightly fixed to the outer wall of the box body 1 with matching bolts to ensure a firm connection and prevent loosening during subsequent use. At this time, the notched connecting ring 212 is fixedly connected to the middle of one end of the first mounting plate 211, and the connecting balls 213 are fixedly connected to the upper and lower ends of the connecting ring 212 at one end of the first mounting plate 211. Next, the second connector 22 is installed. The second connector 22 includes a second mounting plate 221 and a connecting block 222. The second mounting plate 221 is firmly fixed to the inner wall surface of the door 3 with bolts. At this time, a rotating hole 223 is provided between the connecting block 222 at the middle of one end of the second mounting plate 221 and between the second mounting plate 221 and the connecting block 222. During installation, the rotating hole 223 on the second connector 22 is precisely aligned with the connecting ring 212 on the first connector 21, allowing the connecting ring 212 to smoothly embed into the rotating hole 223, achieving a rotational connection between the two. Simultaneously, the annular arc opening 224 on the outer wall of the connecting block 222 provides sufficient space for the connecting ring 212 during connection, ensuring smooth rotation. Furthermore, the connecting positions 225 at the top and bottom of the connecting block 222 must accurately engage with the connecting ball 213, allowing the door 3 to rotate flexibly around the connection point between the first connector 21 and the second connector 22. This snap-fit ​​hinge assembly installation method, compared to traditional hinge installation, eliminates the need for complex alignment and adjustment steps, significantly improving installation efficiency. Taking a standard-sized prefabricated substation as an example, using the hinge assembly 2 of this invention to install the door 3, compared to traditional methods, significantly shortens the installation time for each door 3, greatly accelerating the assembly process of the entire substation.

[0023] In this embodiment, the electrical equipment inside the prefabricated substation generates heat. To ensure stable operation of the equipment, heat dissipation vents 31 are provided at both the top and bottom of the cabinet door 3. These vents 31 adopt a special louver design, which can effectively prevent dust, rainwater and other foreign objects from entering the cabinet 1, and can also achieve good heat dissipation through air convection. This structure is a conventional existing technology.

[0024] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
