Description

Technical Field

[0001] The invention relates to the field of power technology such as power transformation / distribution, and in particular to a prefabricated cabin spliced ​​with upper and lower layers of a stereoscopic station and a transformer substation. Background Art

[0002] With the rise of prefabricated cabin substations, multi-layer cabins have adapted to the market trend in order to save land costs. Due to the limitations of transportation conditions, the extra-wide and extra-high prefabricated cabins are decomposed into multiple modules for transportation, and the cabins are spliced ​​with corresponding modules after arriving at the project site.

[0003] The weight of each cabin module ranges from 2t to 20t, which makes it very difficult to splice the cabin up and down. Fine-tuning is extremely uncontrollable, requiring a lot of manpower and material resources to adjust. The splicing is very time-consuming, and the results after adjustment are often uneven, causing large-scale damage to the cabin paint layer.

[0004] More information related to the above technical solution can also be found in the following documents:

[0005] In the Chinese patent with the publication number CN113235644A, a self-anchoring foundation of a prefabricated cabin-type substation is disclosed, including a prefabricated foundation module and a prefabricated cabin module; the foundation module is arranged in a rectangular shape, and the foundation module is provided with a first plug interface and a threading port for cable insertion; the cabin module is provided with a first plug connector at the bottom, and the first plug connector corresponds to the first plug interface; it also includes an enclosure wall, a second plug connector is provided on one side of the enclosure wall, and a second plug interface corresponding to the second plug connector is provided on the side of the foundation module. Compared with the prior art, by decomposing the foundation into several lightweight components, transporting them to the excavated foundation pit for on-site assembly after manufacturing in the factory, the problems of production, transportation, and installation can be effectively solved. Such a modular arrangement greatly improves the overall construction efficiency and has strong practicality.

[0006] In the Chinese patent with publication number CN204720854U, a spliced ​​prefabricated cabin and a prefabricated cabin type substation are disclosed. The spliced ​​prefabricated cabin includes a plurality of cabin modules, and a spliced ​​connection assembly is arranged between two adjacent cabin modules. The cabin module includes a base and a frame fixed on the base. The spliced ​​connection assembly includes a first waterproof gusset, two waterproof columns and a waterproof rubber strip. The cross section of the first waterproof gusset is U-shaped, and a return water groove is formed on one side of the waterproof column. The two adjacent frames are respectively provided with the waterproof columns. The side walls of the two return water grooves are close together, and the waterproof rubber strip is sandwiched between the side walls of the two return water grooves. The two side walls of the first waterproof gusset are respectively inserted into the corresponding return water grooves. The waterproof and weather-resistant performance and reliability of the spliced ​​prefabricated cabin are improved.

[0007] In the process of implementing the present invention, the inventors found that the prior art has the following problems:

[0008] In the prior art, a prefabricated basic module is used to be plugged and fixed with a prefabricated cabin module, wherein the first plug-in component and the first plug-in interface are prefabricated and cannot be disassembled. During the production process, errors are prone to occur between the prefabricated basic module and the prefabricated cabin module, the splicing accuracy is poor, and the cabin module is too heavy, the upper and lower splicing operations are difficult, the adjustment is difficult, and unevenness often occurs, and the cabin paint layer is damaged over a large area. Summary of the invention

[0009] To this end, it is necessary to provide a prefabricated cabin and substation for splicing the upper and lower layers of a stereoscopic station, which can be used to solve the technical problems in the prior art, such as poor splicing accuracy, difficult upper and lower splicing operations, great difficulty in adjustment, and frequent unevenness.

[0010] To achieve the above objectives, in a first aspect, the inventor provides a prefabricated cabin for splicing upper and lower layers of a stereoscopic station, comprising:

[0011] More than two layers of cabins, the more than two layers of cabins are spliced ​​with each other in the vertical direction, wherein the more than two layers of cabins include an upper cabin and a lower cabin, the upper cabin includes an upper base, the lower cabin includes a top frame, and the upper base is arranged on the top frame; and

[0012] A mortise and tenon assembly, the mortise and tenon assembly comprising a mortise component and a mortise hole structure, a first mounting platform is provided on the upper base, a second mounting platform is provided on the top frame, the mortise component is provided on the first mounting platform or the second mounting platform, and the mortise hole structure is provided on the second mounting platform or the first mounting platform accordingly;

[0013] The upper cabin body is installed on the lower cabin body through the cooperation between the tenon component and the mortise structure, and the tenon component is provided with a guide portion for guiding the mortise structure.

[0014] Different from the prior art, the above technical solution includes a tenon component and a mortise structure through the tenon and mortise assembly, a first mounting platform is provided on the upper base, a second mounting platform is provided on the top frame, the tenon component is provided on the first mounting platform or the second mounting platform, and the mortise structure is correspondingly provided on the second mounting platform or the first mounting platform; the upper cabin is installed on the lower cabin through the cooperation of the tenon component and the mortise structure, and the tenon component is provided with a guide part for guiding the mortise structure. In this way, the mortise structure of the upper cabin can be guided by the guide part on the tenon component. In the actual splicing process, as long as the mortise structure and the tenon component are roughly aligned, the upper cabin will slide down along the direction of the guide part of the tenon component according to gravity and reach the designated position, which can effectively improve the splicing accuracy, improve the splicing efficiency, reduce the difficulty of cabin splicing, save costs, and reduce cabin splicing time and labor costs.

[0015] As an implementation mode of the present invention, the first mounting platform is arranged in a horizontal direction, the first mounting platform is fixed on the upper base, and the mortise structure is arranged on the first mounting platform;

[0016] The second mounting platform is arranged along a horizontal direction, the second mounting platform is fixed on the top frame, and the tenon component is installed on the second mounting platform along a vertical direction.

[0017] In this way, the tenon component is arranged on the second installation platform along the vertical direction. During installation, the mortise structure leans downward on the guide part of the tenon component along the vertical direction, and can slide downward along the direction of the guide part to reach the designated splicing position, making it convenient for the upper cabin to be installed on the lower cabin.

[0018] In the actual production process, a plurality of guide parts are provided on the tenon component, and the plurality of guide parts are arranged around the center of the tenon component, and the mortise structure is a circular hole structure. The cooperation between the mortise structure and the plurality of guide parts can slide the upper cabin body to a preset designated position in the horizontal direction, so as to improve the splicing accuracy between the upper cabin body and the lower cabin body.

[0019] As an embodiment of the present invention, a special-shaped hole for allowing the tenon component to pass through is arranged on the second mounting platform, and the tenon component is arranged so that the tenon component can pass through the special-shaped hole by rotating the tenon component.

[0020] In this way, the tenon component can be disassembled by rotating the tenon component so that the tenon component passes through the special-shaped hole, and the tenon component can be recycled and reused, thereby saving materials and reducing costs.

[0021] As an embodiment of the present invention, the tenon component includes more than two guiding portions extending outward, and the special-shaped hole is correspondingly provided with more than two extending portions.

[0022] In this way, mainly through the cooperation between the plurality of guide parts on the tenon component and the extension part, the tenon component can be left on the second mounting platform, or the tenon component can pass through the extension part, which facilitates the removal of the tenon component. At the same time, the provision of more than two outwardly extending guide parts can improve the splicing accuracy between the upper cabin and the lower cabin.

[0023] As an embodiment of the present invention, the mortise and tenon assembly also includes a third mounting platform, which is fixed on the top frame, and is arranged in a horizontal direction. The third mounting platform is arranged below the second mounting platform, and the third mounting platform is also correspondingly provided with a special-shaped hole for allowing the tenon component to pass through.

[0024] In this way, the tenon component can be set on the second mounting platform or on the third mounting platform. Since the second mounting platform and the third mounting platform are located at different heights in the vertical direction, the height of the tenon component can be adjusted to adapt to different application scenarios, thereby improving the applicability of the tenon component without designing tenon components of multiple heights.

[0025] As an implementation manner of the present invention, the first mounting platform is a reinforcing plate, the reinforcing plate is a triangular structure, and two sides of the reinforcing plate are respectively connected to the upper base.

[0026] In this way, the situation in which the first mounting platform is prone to failure during use can be avoided.

[0027] As an implementation manner of the present invention, the second mounting platform is a reinforcing plate, the reinforcing plate is a triangular structure, and two sides of the reinforcing plate are respectively connected to the top frame.

[0028] In this way, the situation in which the second mounting platform is prone to failure during use can be avoided, thereby improving the supporting strength of the tenon component.

[0029] As an embodiment of the present invention, the upper and lower prefabricated cabins of the stereoscopic station also include a labyrinth waterproof component, and a storage space for accommodating the labyrinth waterproof component is reserved at the bottom of the upper cabin body. The labyrinth waterproof component is arranged on the lower cabin body, and the labyrinth waterproof component is located behind the gap between the upper cabin body and the lower cabin body, and is used to prevent water in the gap between the upper cabin body and the lower cabin body from entering the prefabricated cabin.

[0030] In this way, a receiving space is provided at the bottom of the upper cabin to accommodate the labyrinth waterproof component, and water entering from the gap between the upper cabin and the lower cabin is blocked by the labyrinth waterproof component, thereby preventing water from entering the interior of the prefabricated cabin.

[0031] As an embodiment of the present invention, a rubber pad is arranged in the gap between the upper cabin and the lower cabin, the bottom of the upper cabin is arranged on the lower cabin through the rubber pad, and a waterproof structural adhesive is arranged on the outside of the gap between the upper cabin and the lower cabin, and the maze waterproof part has a guide inclined plate, which is used to guide the bottom of the upper cabin.

[0032] In this way, the rubber pad can be compacted by the gravity of the upper cabin to enhance the waterproof performance of the waterproof mechanism. After the upper cabin and the lower cabin are assembled, waterproof structural adhesive is injected at the external joints to further enhance the waterproof performance. When the upper cabin is installed, the upper cabin can slide down along the guide inclined plate through gravity to protect the maze waterproof parts from damage.

[0033] To achieve the above objectives, in a second aspect, the inventor provides a substation, comprising a prefabricated cabin with upper and lower layers spliced ​​together as described in any one of the three-dimensional stations provided by the inventors above.

[0034] Different from the prior art, the substation of the technical solution of the present application can guide the mortise structure of the upper cabin through the guide part on the tenon component. In the actual splicing process, as long as the mortise structure and the tenon component are roughly aligned, the upper cabin will slide down along the direction of the guide part of the tenon component according to gravity to reach the designated position, which can effectively improve the splicing accuracy, improve the splicing efficiency, reduce the difficulty of cabin splicing, save costs, and reduce cabin splicing time and labor costs.

In the actual splicing process, as long as the mortise structure and the tenon component are roughly aligned, the upper cabin will slide down along the direction of the guide portion of the tenon component according to gravity and reach the designated position, which can effectively improve the splicing accuracy, improve the splicing efficiency, reduce the difficulty of cabin splicing, save costs, and reduce cabin splicing time and labor costs.

[0077] The present embodiment relates to a prefabricated cabin with upper and lower layers spliced ​​together in a stereo station and a substation, which can be applied in the technical field of stereo substations and power distribution stations.

[0078] According to some embodiments of the present application, please refer to Figures 1 to 10 The present embodiment relates to a prefabricated cabin for splicing upper and lower layers of a stereoscopic station, comprising more than two layers of cabin bodies and mortise and tenon assemblies, wherein the more than two layers of cabin bodies are spliced ​​with each other in a vertical direction, wherein the more than two layers of cabin bodies comprise an upper cabin body 1 and a lower cabin body 2, wherein the upper cabin body 1 comprises an upper base 11, and the lower cabin body 2 comprises a top frame 21, and the upper base 11 is arranged on the top frame 21; the mortise and tenon assembly comprises a tenon component 31 and a mortise structure 32, a first mounting platform 12 is arranged on the upper base 11, and a second mounting platform 22 is arranged on the top frame 21, the tenon component 31 is arranged on the first mounting platform 12 or the second mounting platform 22, and the mortise structure 32 is correspondingly arranged on the second mounting platform 22 or the first mounting platform 12; wherein the upper cabin body 1 is mounted on the lower cabin body 2 by the cooperation of the tenon component 31 and the mortise structure 32, and the tenon component 31 is provided with a guide portion 311 for guiding the mortise structure 32.

[0079] In this embodiment, a substation refers to a place in a power system where voltage and current are transformed, electric energy is received, and electric energy is distributed.

[0080] In this embodiment, the upper base 11 is provided with a mortise structure 32, and the lower layer is provided with a tenon member 31 to support the platform, and a special-shaped hole 221 is built in, so that the tenon member 31 is detachable. In other embodiments, the upper base 11 is provided with a tenon member 31, and the lower layer is provided with a mortise structure 32.

[0081] In this embodiment, the tenon component 31 and the mortise structure 32 are both made of metal. The tenon component 31 has a relatively high hardness and is suitable for multiple uses.

[0082] In this way, through the mortise and tenon assembly including the tenon component 31 and the mortise structure 32, a first mounting platform 12 is arranged on the upper base 11, a second mounting platform 22 is arranged on the top frame 21, the tenon component 31 is arranged on the first mounting platform 12 or the second mounting platform 22, and the mortise structure 32 is correspondingly arranged on the second mounting platform 22 or the first mounting platform 12; the upper cabin 1 is installed on the lower cabin 2 through the cooperation of the tenon component 31 and the mortise structure 32, and a guide portion 311 for guiding the mortise structure 32 is arranged on the tenon component 31.

[0086] The second installation platform 22 is arranged along the horizontal direction, the second installation platform 22 is fixed on the top frame 21, and the tenon component 31 is installed on the second installation platform 22 along the vertical direction.

[0087] In this way, the tenon component 31 is arranged on the second installation platform 22 along the vertical direction. During installation, the mortise structure 32 leans downward on the guide portion 311 of the tenon component 31 along the vertical direction, and can slide downward along the direction of the guide portion 311 to reach the designated splicing position, thereby facilitating the installation of the upper cabin 1 on the lower cabin 2.

The cooperation between the mortise structure 32 and the plurality of guide portions 311 can slide the upper cabin 1 to a preset designated position in the horizontal direction, so as to improve the splicing accuracy between the upper cabin 1 and the lower cabin 2.

[0089] According to some embodiments of the present application, optionally, a special-shaped hole 221 for the tenon member 31 to pass through is provided on the second mounting platform 22 , and the tenon member 31 is configured so that the tenon member 31 can pass through the special-shaped hole 221 by rotating the tenon member 31 .

[0090] In this way, the tenon component 31 can be disassembled by rotating the tenon component 31 so that the tenon component 31 passes through the special-shaped hole 221 , and the tenon component 31 can be recycled and reused, thereby saving materials and reducing costs.

[0091] According to some embodiments of the present application, optionally, the tenon component 31 includes more than two guiding portions 311 extending outward, and the special-shaped hole 221 is correspondingly provided with more than two extending portions 222 .

[0092] In this way, mainly through the cooperation between the plurality of guide portions 311 on the tenon member 31 and the extension portion 222, the tenon member 31 can be left on the second mounting platform 22, or the tenon member 31 can pass through the extension portion 222, so as to facilitate the removal of the tenon member 31. At the same time, the provision of more than two outwardly extending guide portions 311 can improve the splicing accuracy between the upper cabin 1 and the lower cabin 2.

[0093] In other embodiments, if the center error of the upper and lower mortise and tenon structures is large and the protruding tenon component 31 hinders the cabin assembly, the tenon component 31 can be rotated and adjusted to the same angle as the special-shaped hole 221 of the second mounting platform 22, and then dragged downward to remove it, thereby eliminating the obstruction to the cabin assembly.

[0094] According to some embodiments of the present application, optionally, the mortise and tenon assembly also includes a third mounting platform 23, which is fixed on the top frame 21, and is arranged in a horizontal direction. The third mounting platform 23 is arranged below the second mounting platform 22, and the third mounting platform 23 is also correspondingly provided with a special-shaped hole 221 for the tenon component 31 to pass through.

[0095] In this way, the tenon component 31 can be set on the second mounting platform 22 and also on the third mounting platform 23. Since the second mounting platform 22 and the third mounting platform 23 are located at different heights in the vertical direction, the height of the tenon component 31 can be adjusted to adapt to different application scenarios, thereby improving the applicability of the tenon component 31 without designing tenon components 31 of multiple heights.

[0096] According to some embodiments of the present application, optionally, the first mounting platform 12 is a reinforcing plate, the reinforcing plate is a triangular structure, and two sides of the reinforcing plate are respectively connected to the upper base 11.

[0099] In this way, the second mounting platform 22 can be prevented from failing easily during use, thereby improving the supporting strength of the tenon member 31 .

[0101] 1. Make a removable tenon component 31, which is welded on three sides. Figure 1 ;

[0102] 2. Add a tenon support platform (installation platform) at the lower end, with two layers, and special-shaped holes 221 on the plate for removing the tenon components 31, see Figure 2 and Figure 3 ;

[0103] 3. The upper structure is added with a mortise hole structure 32, with a central opening whose diameter is 3 to 5 mm larger than the outer diameter of the tenon member 31. If the strength of the mortise hole structure 32 is insufficient, it is necessary to appropriately add a support plate for reinforcement, see Figure 6 , Figure 7 ;

[0104] 4. Insert the tenon member 31 into the tenon support platform (installation platform) along the special-shaped hole 221, see Figure 4 ;

[0105] 5. After the tenon member 31 is connected to the support plate (installation platform), it is rotated to a certain angle and misaligned with the special-shaped hole 221 to ensure that the tenon member 31 is seated on the support plate (installation platform) and does not fall out. Figure 5 ;

[0106] 6. Align the mortise structure 32 of the upper module with the structural direction of the lower tenon member 31, and rely on its own gravity to directly fall down along the guide part 311 to close, with precise alignment, and complete the closing in one go. Figure 8 , Fig. 9 , Fig.10 ;

[0107] 7. If the center error of the upper and lower mortise and tenon structures is large and the protruding tenon component 31 hinders the cabin assembly, the tenon component 31 can be rotated and adjusted to the same angle as the special-shaped hole 221 of the support platform (installation platform) and then dragged downward to remove the cabin assembly obstacle. The closing work is carried out according to other mortise and tenon structures.

[0108] According to some embodiments of the present application, optionally, the upper and lower prefabricated cabins of the stereoscopic station further include a labyrinth waterproof component 4, a receiving space 13 for receiving the labyrinth waterproof component 4 is reserved at the bottom of the upper cabin body 1, the labyrinth waterproof component 4 is arranged on the lower cabin body 2, and the labyrinth waterproof component 4 is located behind the gap between the upper cabin body 1 and the lower cabin body 2, and is used to prevent water in the gap between the upper cabin body 1 and the lower cabin body 2 from entering the prefabricated cabin.

[0109] In this way, a receiving space 13 is provided at the bottom of the upper cabin 1 to accommodate the labyrinth waterproof member 4. Water entering from the gap between the upper cabin 1 and the lower cabin 2 is blocked by the labyrinth waterproof member 4, thereby preventing water from entering the interior of the prefabricated cabin.

[0110] According to some embodiments of the present application, optionally, a rubber pad 41 is provided in the gap between the upper cabin 1 and the lower cabin 2, the bottom of the upper cabin 1 is provided on the lower cabin 2 through the rubber pad 41, a waterproof structural adhesive 42 is provided on the outside of the gap between the upper cabin 1 and the lower cabin 2, and the maze waterproof component 4 has a guide inclined plate 43, which is used to guide the bottom of the upper cabin 1.

[0111] In this way, the rubber pad 41 can be compacted by the gravity of the upper cabin 1 to enhance the waterproof performance of the waterproof mechanism. After the upper cabin 1 and the lower cabin 2 are assembled, the waterproof structural adhesive 42 is injected at the external joints to further enhance the waterproof performance. When the upper cabin 1 is installed, the upper cabin 1 can slide downward along the guide inclined plate 43 by gravity to protect the labyrinth waterproof component 4 from damage.

[0112] The present embodiment also relates to a substation, comprising a prefabricated cabin with upper and lower layers spliced ​​together as in any of the above three-dimensional stations.
