[0038] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0039] The principle and concept of this utility model is as follows: the cabin uprights and cabin side panels are inserted and connected on the cabin base, and the various panels are connected by the insertion structure to form an assembled prefabricated cabin; since the insertion structure is provided between the cabin base and the cabin uprights and cabin side panels, the insertion structure strengthens the connection strength between the cabin uprights, cabin side panels and cabin base.

[0040] Based on the above principles, this utility model provides several embodiments of prefabricated modular cabins for further explanation.

[0041] Based on the above concepts and principles, in a basic embodiment, such as Figure 1 In the provided embodiment, the prefabricated modular cabin includes a cabin base 1 and a plurality of cabin columns 4 mounted on the cabin base 1. Cabin side panels 5 are inserted between adjacent cabin columns 4. One of the bottom edges of the cabin base 1 and the cabin side panel 5 is provided with an insertion groove 11 structure, and the other is provided with an insertion protrusion structure. The cabin columns 4 and the cabin side panels 5 are inserted and connected to the cabin base 1 through the insertion groove 11 and the insertion protrusion.

[0042] Based on the above embodiments, in one embodiment, multiple insertion grooves 11 or insertion protrusions are arranged along the edge of the cabin base 1, and the multiple insertion grooves and insertion protrusions are discontinuous, resulting in low connection strength; in a more preferred embodiment, such as Figures 7-8 In the provided embodiment, the hull base 1 is provided with a plug-in groove 11. The plug-in groove 11 is arranged in a sealed annular shape around the edge of the hull base 1. In this way, the hull column 4 and the hull side wall 5 with plug-in structure are plugged into the plug-in groove 11 that is continuously arranged circumferentially along the edge of the hull base 1, which increases the plug-in connection area and improves the connection strength. At the same time, the plug-in structure composed of the continuously arranged circumferential plug-in groove 11 and the plug-in protrusion can also play a waterproof role.

[0043] Based on the above embodiments, in one embodiment, the bottom of the cabin column 4 and the bottom of the cabin side wall 5 are provided with insertion protrusions. The width of the insertion protrusions is equal to the width of the insertion grooves 11 provided on the cabin base 1, and less than the plate thickness of the cabin column 4 and the cabin side wall 5. The cabin column 4 and the cabin side wall 5 are inserted into the insertion grooves 11 provided on the cabin 1 through the insertion protrusions. In an optimized embodiment, such as... Figures 1-8In the provided embodiment, the cabin base 1 is provided with a plug-in groove 11, the thickness of the cabin column 4 is the same as the width of the plug-in groove 11 provided on the cabin base 1, and the bottom of the cabin column 4 forms a plug-in protrusion that can be directly inserted into the plug-in groove 11; the thickness of the cabin side wall 5 is the same as the width of the plug-in groove 11 provided on the cabin base 1, and the bottom of the cabin side wall 5 forms a plug-in protrusion that can be directly inserted into the plug-in groove 11. This avoids the need to provide additional plug-in protrusions with a thickness smaller than the bottom of the cabin column 4 and the cabin side wall 5, thus improving the connection strength.

[0044] Based on the above embodiments, in one embodiment, the cabin support columns 4 include corner columns 41 inserted into the four corners of the cabin base 1. The corner columns 41 are L-shaped column structures, and insertion structures are provided on both sides of the corner columns 41. Cabin side panels 5 are inserted between the four corner columns 41 to form prefabricated cabin side walls. If the length of the cabin base 1 is long, the length of the cabin side panels 5 inserted in the length direction of the cabin base 1 also increases, increasing the assembly difficulty and manufacturing cost. In a more preferred embodiment, such as Figure 4 , Figure 5 In the provided embodiment, the cabin support column 4 includes corner support columns 41 located at the four corners of the cabin base 1 and intermediate support columns 42 located between the corner support columns 41. The intermediate support column 42 is a hollow profile with support column slots on both sides. The corner support columns 41 are L-shaped column structures. Both sides of the cabin support column 4 are provided with insertion structures. Cabin side panels 5 are inserted between the intermediate support columns 42 and the corner support columns 41, and between adjacent intermediate support columns 42, thereby forming the prefabricated cabin side wall. The intermediate support column 42 serves as a transition connector inserted between adjacent cabin side panels 5 in the length direction of the cabin base 1, which simplifies the assembly process of the prefabricated cabin and strengthens the connection strength of the prefabricated cabin side wall.

[0045] Based on the above embodiments, in one embodiment, such as Figure 4 , Figure 5 In the provided embodiment, both sides of the cabin pillar 4 are provided with pillar slots 43 for inserting the cabin side wall 5, and the two sides of the cabin side wall 5 are inserted into the pillar slots 43.

[0046] Based on the above embodiments, in one embodiment, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 In the provided embodiment, the cabin side wall 5 is a rectangular plate structure. The two sides of the cabin side wall 5 are provided with wall panel protrusions, which are inserted into the above-mentioned column slots 43. The outer surface of the prefabricated cabin side wall formed after the cabin side wall 5 and the cabin column 4 are installed is flush with each other.

[0047] Based on the above embodiments, in one embodiment, such asFigure 1 , Figure 6 and Figure 9 In the provided embodiment, the cabin side wall 5 includes a bulkhead 51 and a door 52. The door 52 is composed of a door frame 521 and a door leaf 522. The door frame 521 has wall panel protrusions on both sides in the length direction for insertion into the aforementioned column slot 43.

[0048] Based on the above embodiments, in one embodiment, the size of the bulkhead 51 is customized according to the volume of the power equipment installed inside the prefabricated cabin, thereby controlling the overall volume and capacity of the prefabricated cabin; in a more preferred embodiment, such as Figure 1 In the provided embodiment, multiple bulkhead panels 51 inserted on the hull base 1 have the same structural dimensions. The overall volume of the prefabricated hull can be controlled by increasing or decreasing the number of bulkhead panels 51 installed on the hull base 1 and the size of the hull base 1. The bulkhead panels 51 with the same structural dimensions can be mass-produced and modularly assembled. The overall volume and capacity of the prefabricated hull can be changed simply by customizing the hull base 1 of different sizes.

[0049] Based on the above embodiments, in one embodiment, such as Figure 1 In the provided embodiment, the prefabricated modular cabin also includes an upper ring beam 3 and a hatch cover 2 installed on the upper end of the upper ring beam 3; the upper ring beam 3 is a closed ring structure, and an upper ring beam slot 31 is provided on the lower side of the upper ring beam 3, which is inserted and connected to the cabin column 4 and the cabin side wall 5.

[0050] This utility model also provides an embodiment of a prefabricated substation for further explanation.

[0051] Based on the above embodiments, such as Figures 1-9 In the provided embodiments, the prefabricated substation includes a prefabricated modular module and power equipment installed in the prefabricated modular module, wherein the prefabricated modular module is the prefabricated modular module in the above embodiments.
