[0059] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0060] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0061] like Figures 1 to 23 As shown:

[0062] First embodiment:

[0063] A modular box-type substation housing provided by an embodiment of the present invention comprises a box frame 1, wherein the first side panels 2 are plugged and installed on two sides of the box frame 1, and the second side panels 3 are plugged and installed on the other two sides of the box frame 1. The box frame 1 cooperates with the first side panels 2 and the second side panels 3 to form a substation built-in cavity, a top frame 4 is fixedly installed on the upper part of the box frame 1, and a heat preservation shielding plate 5 is plugged and pasted on the upper part of the top frame 4, and a bottom plate 6 is laid on the bottom of the box frame 1, and a plurality of bottom plates 6 block the bottom opening of the box frame 1; the box frame 1 comprises a bottom bracket 101, and the bottom bracket 101 has four A support column 103 is installed in the upper part of the corner, and the first side panel 2 or the second side panel 3 is installed between two adjacent support columns 103; a top bracket 102 is also provided on the upper part of the bottom bracket 101, and the lower parts of the four corners of the top bracket 102 are plugged into the upper parts of the four support columns 103; the bottom bracket 101 and the top bracket 102 have the same structure, and the bottom bracket 101 includes a first telescopic plate 1011, and two first telescopic plates 1011 are provided. A second telescopic plate 1012 is installed in between the two ends of the two first telescopic plates 1011 through a connecting piece 1013.

[0064] The above-mentioned modular box-type substation shell is designed to effectively solve the various inconveniences caused by the large size of traditional box-type substations during transportation and installation, especially for the problem of frequent transportation and assembly of regional substations. The core concept is to split the various components of the substation into several modules, and the entire substation can be quickly built through simple plug-in and assembly.

[0065] Firstly, the main structure of the substation is composed of a box frame 1, on both sides of which a first side panel 2 and a second side panel 3 are respectively inserted, and these side panels cooperate with the box frame 1 to form a closed substation internal cavity with ample internal space.

[0066] In order to further improve the sealing and functionality of the substation, a top frame 4 is installed on the upper part of the box frame 1, and an insulation shield 5 is plugged and pasted on the top frame 4 to ensure that the internal equipment of the substation can operate stably under different climatic conditions. At the same time, at the bottom of the box frame 1, we laid several bottom plates 6, which can not only effectively prevent dust and moisture from entering the substation, but also serve as a supporting structure to enhance the overall stability of the substation.

[0067] The box frame 1, top frame 4, insulation shield 5, bottom plate 6, first side plate 2 and second side plate 3 are all modularly designed and can be manufactured and transported separately, and quickly assembled into a complete substation when needed. This design not only greatly saves transportation costs, but also improves installation efficiency, making the construction of substations more flexible and efficient.

[0068] Specifically speaking of the modular design of the box frame 1: the box frame 1 is composed of a bottom bracket 101 and a top bracket 102, both of which have the same structure. Specifically, the bottom bracket 101 includes two first telescopic plates 1011, and a second telescopic plate 1012 is plugged between the two first telescopic plates through a connector 1013. Such a design allows the box frame 1 to be adjusted according to actual needs. During transportation, the first telescopic plate 1011 and the second telescopic plate 1012 are in a retracted state. During installation, the first telescopic plate 1011 and the second telescopic plate 1012 can be extended outward to be widened and adjusted to adapt to substations of different sizes and shapes. At the same time, due to the use of a plug-in structure, the various parts of the box frame 1 can be easily disassembled and assembled, further enhancing its modular characteristics.

[0069] In general, by modularizing the splitting and combination of the various components of the substation, various problems in the transportation and installation of traditional box-type substations have been effectively solved, which not only improves the construction efficiency and quality of the substation, but also reduces costs, providing strong support for the construction and development of urban power grids.

[0070] In this embodiment, the first telescopic plate 1011 includes a main support plate 10111, a plurality of first screw holes 10114 are opened inside the main support plate 10111, the main support plate 10111 is hollow, two auxiliary support plates 10112 are slidably installed on both sides of the main support plate 10111, slots 10115 are opened inside the auxiliary support plates 10112, and a plurality of support blocks 10113 are also slidably installed inside the main support plate 10111, and the shape of the support blocks 10113 is the same as the cross-sectional shape of the auxiliary support plates 10112.

[0071] The first telescopic plate 1011 is an important component of the box frame 1, and bears the dual tasks of providing stable support and realizing telescopic function. It not only provides flexible adaptability for the box-type substation, but also ensures the stability and reliability of the structure.

[0072] Specifically, the core structure of the first telescopic plate 1011 is the main support plate 10111, and a number of first screw holes 10114 are cleverly opened inside the main support plate 10111. The design of these screw holes not only facilitates subsequent assembly and fixation, but also increases the adjustability and stability of the overall structure.

[0073] Two auxiliary support plates 10112 are slidably installed on both sides of the main support plate 10111. The two auxiliary support plates 10112 can slide freely along the track of the main support plate 10111, thereby realizing the telescopic function of the first telescopic plate 1011. When the width of the box frame 1 needs to be adjusted, it is only necessary to slide the auxiliary support plates 10112 outward to the appropriate position. This design not only enables the box-type substation to adapt to installation environments of different sizes, but also greatly improves the flexibility and efficiency of installation.

[0074] However, when the auxiliary support plate 10112 slides outward, the supporting force in the middle position of the main support plate 10111 may be relatively weak. In order to solve this problem, a number of support blocks 10113 are slidably installed inside the main support plate 10111. The shapes of these support blocks 10113 are the same as the cross-sectional shape of the auxiliary support plate 10112, and can be perfectly embedded in the hollow part of the main support plate 10111. When the auxiliary support plate 10112 slides outward, the support blocks 10113 are moved to the middle position to provide additional supporting force, thereby ensuring the stability and safety of the overall structure. The auxiliary support plate 10112 and the support blocks 10113 are then fixed to the upper part of the main support plate 10111 with bolts for reinforcement.

[0075] In summary, the design of the first telescopic plate 1011 not only realizes the telescopic function, but also solves the problem of weak supporting force in the middle position after the auxiliary support plate 10112 slides, and can provide stable and reliable support in installation environments of different sizes and shapes.

[0076] In this embodiment, the connecting member 1013 includes a connecting plate 10131, and plug plates 10132 are fixedly connected on both sides of the connecting plate 10131. A socket 10133 is fixedly connected to the upper part of the connecting plate 10131. The socket 10133 is provided with a second screw hole 10134. Third screw holes 10135 are provided on both sides of the connecting plate 10131. There are three second screw holes 10134, two of which are staggered with another second screw hole 10134. The two plug plates 10132 are respectively plugged into the first telescopic plate 1011 and the second telescopic plate 1012. The four connecting members 1013 cooperate with the two first telescopic plates 1011 and the second telescopic plates 1012 to form a bottom bracket 101 or a top bracket 102.

[0077] The connecting piece 1013 is a key component constituting the bottom bracket 101 or the top bracket 102 , which not only ensures the stability of the bracket structure but also simplifies the assembly process.

[0078] The core part of the connector 1013 is the connecting plate 10131, which is used to bear and disperse the pressure generated by the weight. The connecting plate 10131 is fixedly connected with plug plates 10132 on both sides. These plug plates 10132 are precisely designed to be tightly plugged into the auxiliary support plate 10112 of the first telescopic plate 1011 and the auxiliary support plate 10112 of the second telescopic plate 1012. This plug-in design not only ensures the stability of the structure, but also greatly simplifies the assembly steps and improves work efficiency.

[0079] A socket 10133 is fixedly connected to the upper part of the connecting plate 10131 for plugging in the mounting support column 103. Third screw holes 10135 are also opened on both sides of the connecting plate 10131 to further enhance the stability of the overall structure. Through these third screw holes 10135, fasteners such as bolts can be used to firmly connect the connecting piece 1013 and the telescopic plate together.

[0080] During the assembly process, the four connecting parts 1013 cooperate closely with the two first telescopic plates 1011 and the second telescopic plates 1012 to form the basic frame of the bottom bracket 101 or the top bracket 102. This integrated assembly method not only simplifies the installation steps, but also ensures the stability and durability of the bracket.

[0081] In this embodiment, the support column 103 includes a first half support column 1031 and a second half support column 1033. The first half support column 1031 is fixedly connected to a first docking plate 1032 on the upper portion, and the second half support column 1033 is fixedly connected to a second docking plate 1034 on the upper portion. The first half support column 1031 and the second half support column 1033 are spliced ​​to form a square support column. The first docking plate 1032 and the second docking plate 1034 are spliced ​​to form a square plug rod 701. The square plug rod 701 is plugged into the socket 10133. The square plug rod 701 is provided with two, and the two square plug rods 701 are respectively provided with At both ends of the square pillar, the two ends of the square pillar are respectively connected to the bottom bracket 101 and the top bracket 102 through a square plug rod 701, and the first half pillar 1031 and the second half pillar 1033 are provided with docking screw holes 1035, and there are three docking screw holes 1035. The three docking screw holes 1035 are arranged corresponding to the three second screw holes 10134. The first half pillar 1031 and the second half pillar 1033 are also respectively provided with a first sliding groove 1036, and the first side panel 2 or the second side panel 3 is installed inside the first sliding groove 1036 of the two adjacent support columns 103.

[0082] The support column 103 is a key supporting structure of the enclosure of the box-type substation, which can be easily assembled and disassembled while ensuring the stability of the structure.

[0083] The support column 103 consists of a first half-pillar 1031 and a second half-pillar 1033. This split design greatly simplifies the transportation and storage process. The first half-pillar 1031 is fixedly connected to the upper part with a first docking plate 1032, while the second half-pillar 1033 is fixedly connected to the upper part with a second docking plate 1034. When the first half-pillar 1031 and the second half-pillar 1033 are spliced ​​together, they form a solid square pillar. At the same time, the first docking plate 1032 and the second docking plate 1034 are also spliced ​​into a square plug rod 701.

[0084] The square plug rod 701 is configured to be plugged into the socket 10133, thereby realizing a quick connection between the support column 103 and the bottom bracket 101 or the top bracket 102; specifically, two square plug rods 701 are provided, which are respectively located at the two ends of the square pillar, so that the support column 103 can simultaneously connect the bottom bracket 101 and the top bracket 102, playing an important role like a bridge.

[0085] In order to further enhance the stability of the structure, the first half-pillar 1031 and the second half-pillar 1033 are provided with docking screw holes 1035, and these screw holes are arranged corresponding to the second screw holes 10134 on the socket 10133, so that the user can conveniently use bolts or other fasteners to tightly fix the support column 103 and the socket 10133 together. There are three docking screw holes 1035 to ensure the firmness and reliability of the connection.

[0086] In addition, the first half-pillar 1031 and the second half-pillar 1033 are respectively provided with first slide grooves 1036. The design of these slide grooves greatly facilitates the installation of the first side panel 2 and the second side panel 3. The first side panel 2 or the second side panel 3 can be easily plugged in and installed inside the first slide grooves 1036 of the two adjacent support columns 103, thereby quickly building the outer shell structure of the substation.

[0087] In summary, the support column 103 not only ensures the stability of the structure but also greatly simplifies the assembly process through the splicing and plug-in design, as well as the precise screw hole and slide groove layout. This design concept makes the construction of the box-type substation more efficient, flexible and reliable.

[0088] In this embodiment, the top frame 4 cooperates with the heat-insulating shielding plate 5 to form a cover plate for shielding the top of the box frame 1. The top frame 4 includes a first support frame 401. Two first support frames 401 are symmetrically installed on the upper part of the box frame 1. Second support frames 402 are also provided on both sides of the two first support frames 401. A third support frame 403 is also provided on the side of the second support frame 402 away from the first support frame 401. The second support frame 402 and the third support frame 403 are fixedly installed inside the box frame 1. The top shape of the box frame 1 matches the first support frame 401, the second support frame 402 and the third support frame 403. A plurality of support frames for ventilation and heat dissipation are integrated and installed inside the first side panel 2. The grille plate 201 has a door panel 301 rotatably installed inside the second side plate 3; a second sliding groove 202 is also provided on the inner side of the first side plate 2, and a partition plate 7 is slidably inserted inside the second sliding groove 202 of the two first side plates 2, and the partition plate 7 includes a square plug rod 701, and the square plug rod 701 is slidably installed in the second sliding groove 202 of the first side plate 2, and a plate body 702 is rotatably installed on one side of the square plug rod 701, and the plate body 702 has a placement groove 703, and one end of the placement groove 703 of the plate body 702 is also provided with a grabbing groove 705 that penetrates the placement groove 703, and a limiting rod 704 for limiting the two plate bodies 702 is placed inside the placement groove 703 of the two plate bodies 702.

[0089] In the design of the box-type substation, the first side plate 2 and the second side plate 3 not only play the role of enclosure and support, but also integrate multiple functions to meet the actual needs during the operation of the substation.

[0090] Firstly, a plurality of grille plates 201 for ventilation and heat dissipation are integrated inside the first side panel 2, which ensures a good ventilation effect and effectively prevents the entry of external debris. The heat generated inside the substation can be dissipated in time through the grille plates 201, thereby ensuring the normal operation of the equipment and extending its service life; at the same time, a door panel 301 is rotatably installed inside the second side panel 3. The door panel 301 is flexibly designed and easy to open and close, providing a convenient passage for the staff, while also ensuring the safety and closedness of the substation.

[0091] A second slide groove 202 is also provided on the inner side of the first side panel 2 for use with the foldable partition 7. Specifically, the partition 7 can be slidably inserted into the second slide groove 202 of the two first side panels 2. The partition 7 is composed of a square plug rod 701 and a plate body 702. The square plug rod 701 is slidably installed in the second slide groove 202 of the first side panel 2, thereby ensuring the stability and adjustability of the partition 7. The plate body 702 is connected to the square plug rod 701 by a rotating installation method, so that the plate body 702 can be unfolded when needed and folded away when not needed.

[0092] A placement slot 703 is also provided on the plate body 702 for placing a limit rod 704 in the unfolded state. When the two plate bodies 702 are butt-jointed, the limit rod 704 can effectively limit the movement of the plate body 702, thereby ensuring the stability and load-bearing capacity of the partition 7. A grabbing slot 705 that passes through the placement slot 703 is also provided at one end of the placement slot 703 of the plate body 702, so that when the partition 7 is not in use, the staff can easily reach in through the grabbing slot 705 to take out the limit rod 704, thereby releasing the limit and easily storing and folding the plate body 702. The actual needs during the operation of the substation are fully considered. The breathable grid plate 201, the door panel 301 and the foldable partition 7, etc., together provide a strong guarantee for the efficient and safe operation of the box-type substation.

[0093] Second embodiment:

[0094] In this embodiment, the substation housing further includes a first stopper 104, which includes a lifting column 1041. The lifting column 1041 is slidably mounted on the upper portion of the connecting member 1013 through a first spring 1042. The end of the lifting column 1041 away from the first spring 1042 is in active contact with the support column 103. A tooth plate 1043 is fixedly connected to the lower portion of the lifting column 1041. A rotating rod 1045 is also rotatably mounted inside the connecting member 1013. One end of the rotating rod 1045 is fixedly connected to a gear 1044, which is meshed with the toothed plate 1043. The end of the rotating rod 1045 away from the gear 1044 is plugged with a square cone 1046, and one side of the square cone 1046 is fixedly connected to a driving rod 1048. An elastic clamping rod 1049 is fixedly installed inside the connecting member 1013. The elastic clamping rod 1049 is driven by the driving rod 1048 to pass through the auxiliary support plate 10112 and plug into the inner wall of the connecting plate 10131. One end of the elastic clamping rod 1049 is in movably contact with the driving rod 1048, and the end of the driving rod 1048 away from the rotating rod 1045 is fixedly connected with the linkage rod 1047, and the linkage rod 1047 is rotatably installed at the center position of the auxiliary support plate 10112, and the end of the linkage rod 1047 away from the driving rod 1048 is fixedly connected with another driving rod 1048, and another three elastic clamping rods 1049 are fixedly installed at the position of the auxiliary support plate 10112 close to the other driving rod 1048. The other three elastic clamping rods 1049 are driven by another driving rod 1048 and movably connected to the main support plate 10111, and the elastic clamping rod 1049 includes a fixing ring 10491, which is fixed inside the connecting piece 1013, and the fixing ring 10491 is slidably installed with a rod body 10493 inside through a second spring 10492, and the fixing rings 10491 of the other three elastic clamping rods 1049 are fixed in the auxiliary support plate 10112.

[0095] When the connecting member 1013 is docked with the support column 103, the lifting column 1041 is supported by the first spring 1042 on the upper part of the connecting member 1013 and can slide along the set track. As the connecting member 1013 and the support column 103 are in close contact, the lifting column 1041 is pushed and starts to move, thereby driving the toothed plate 1043 to move synchronously. When the toothed plate 1043 moves, it drives the gear 1044 meshing with it to rotate, and the other end of the gear 1044 is closely connected to the rotating rod 1045, so the rotation of the gear 1044 is converted into the rotation of the rotating rod 1045, and the square cone 1046 at one end of the rotating rod 1045 is firmly fixed. It is fixedly installed on it, and one side of the square cone 1046 is fixedly connected to a driving rod 1048, and the shape of the driving rod 1048 is specially designed, and one side is a plane, which is convenient for effective contact and transmission with other parts during rotation. When the square cone 1046 rotates with the rotating rod 1045, the driving rod 1048 also rotates accordingly, and the convex part of the driving rod 1048 squeezes the rod body 10493. When squeezed, the rod body 10493 can overcome the pulling force of the second spring 10492 and move outward to insert into the inner wall of the auxiliary support plate 10112, thereby realizing bolt-free fixation between the connecting piece 1013 and the auxiliary support plate 10112.

[0096] At the same time, the other driving rod 1048 is also driven by the linkage rod 1047 and starts to rotate. Similarly, by squeezing the rod body 10493, the other three elastic clamping rods 1049 are driven to insert into the main support plate 10111, completing the bolt-free fixation between the main support plate 10111 and the auxiliary support plate 10112.

[0097] In this embodiment, the first side plate 2 includes a first separation plate 2011 and a second separation plate 2012, which are inserted and installed between two adjacent support columns 103, and the first separation plate 2011 and the second separation plate 2012 are stacked and have the same structure. The second separation plate 2012 is pressed and contacted with the support column 103 and the second separation plate 2012 can be slidably adjusted. A second limiting member 105 is fixedly installed inside the first half support column 1031, and the second limiting member 105 includes a contact plate 1051. The contact plate 1051 is slidably installed inside the first half support column 1031, and one side of the contact plate 1051 is pressed and contacted with the second separation plate 2012. The first fixing rod 1053 is slidably installed inside the first half support column 1031 through a third spring 1053. 54. A push rod 1052 is fixedly connected to the side of the contact plate 1051 away from the second separation plate 2012. The first fixed rod 1054 is driven by the push rod 1052 to plug into the second half-pillar 1033. A linkage plate 1057 is slidably installed inside the first half-pillar 1031 through a fourth spring 1056. A second fixed rod 1059 is fixedly connected to one side of the linkage plate 1057. A push plate 1055 is also fixedly connected to the side of the contact plate 1051 away from the second separation plate 2012. The top plate 1055 is movably in contact with a slider 1058. The slider 1058 is fixed to the side of the linkage plate 1057 away from the second fixed rod 1059. The second fixed rod 1059 is driven by the top plate 1055 and movably plugged into the connector 1013. The connector 1013 is provided with a groove for convenient passage of the push rod 1052.

[0098] In the process of installing the first side panel 2 or the second side panel 3, a unique and ingenious separation design is adopted. Taking the first side panel 2 as an example, it is composed of a first separation plate 2011 and a second separation plate 2012 with the same structure. During installation, the first separation plate 2011 needs to be plugged into one side of one of the support columns 103 first. By applying pressure to press the first separation plate 2011, the internal contact plate 1051 can be forced to reach the maximum compression state. Subsequently, the second separation plate 2012 is plugged into the adjacent support column 103 on the other side. At this time, the previously pressed first separation plate 2011 can be released. Since the contact plate 1051 was in a compressed state before, the first separation plate 2011 will rebound a certain distance under the action of the spring until it is in close contact with the second separation plate 2012. At this point, the installation of the first side panel 2 is completed, and during this process, the contact plate 1051 always remains in a compressed state.

[0099] The compressed state of the contact plate 1051 is transmitted to the first fixing rod 1054 through the top rod 1052, forcing it to be inserted into the second half-pillar 1033, thereby realizing a stable connection between the first half-pillar 1031 and the second half-pillar 1033 without the need for additional bolts or tools. At the same time, the compression of the contact plate 1051 will also drive the top plate 1055 to contact the slider 1058. Under the action of the top rod 1052, the slider 1058 drives the linkage plate 1057 and the second fixing rod 1059 connected thereto to be inserted into the connecting piece 1013. This process also realizes the boltless installation and fixation between the support column 103 and the connecting piece 1013, greatly improving the installation efficiency and the stability of the structure. Specifically, the boltless installation realizes quick connection through structures such as the driving rod 1048 and the elastic clamping rod 1049, without the need to tighten the bolts one by one, thereby greatly shortening the installation time.
