Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cabins, and specifically provides a prefabricated cabin that is convenient for phased construction. Background Art

[0002] Prefabricated cabins are used to install transformers and other equipment. When installing transformers, switchgear and other equipment, they are usually transferred to the prefabricated cabin by cranes and other equipment. After the installation of the transformers and other equipment is completed, the top cover of the prefabricated cabin is installed to complete the capping of the prefabricated cabin.

[0003] However, when equipment within a prefabricated cabin is constructed in phases—for example, during Phase I and Phase II—space is reserved within the cabin for the second phase's equipment to facilitate installation. During this installation, the cabin's roof must be reopened, and the corresponding equipment must be transferred into the cabin using a crane or other equipment. The cabin's roof must then be resealed. Opening the roof compromises the cabin's overall waterproofing. Therefore, the issue of late-stage equipment installation damaging the cabin's waterproofing needs to be addressed urgently. Utility Model Content

[0004] The utility model provides a prefabricated cabin which is convenient for phased construction and is used to solve the problem that the waterproof performance of the prefabricated cabin is damaged by the installation of equipment at a later stage.

[0005] The technical solution of the utility model is as follows:

[0006] A prefabricated cabin convenient for phased construction comprises a side wall provided with an inspection opening, the inspection opening being provided with a detachable closing wall for opening or closing the inspection opening.

[0007] In this solution, an inspection opening is provided on the side wall of the prefabricated cabin body, and subsequent equipment can be transported into the cabin body from the inspection opening by a forklift without removing the top cover of the cabin body, thereby not causing damage to the waterproofing of the prefabricated cabin and solving the problem of the installation of subsequent equipment damaging the waterproofing performance of the prefabricated cabin.

[0008] The equipment to be installed in stages in the prefabricated cabin is different, and the height and size of the equipment to be installed are also different. In order to solve the problem that the height of the enclosed wall cannot be adapted to equipment of different heights, the height of the maintenance opening is equal to the height of the side wall of the cabin.

[0009] The closed wall includes a plurality of wall panel units, which are arranged at the inspection opening along the up-down direction, and each wall panel unit is connected to the inspection opening respectively.

[0010] In this solution, the height of the inspection opening is the same as the height of the side wall of the cabin body. Therefore, the height of the inspection opening is suitable for equipment of various sizes to enter.

[0011] The enclosed wall is only opened when new equipment needs to be installed or when existing equipment requires maintenance. Otherwise, it serves as a side wall. To address the issue of the enclosed wall being too large to be easily installed or removed, the enclosed wall comprises a plurality of wall panel units, which are arranged vertically above the inspection opening, each wall panel unit being connected to a respective inspection opening.

[0012] In this solution, the enclosed wall is composed of several wall panel units. The size and weight of a single wall panel unit are smaller than the size and weight of the entire enclosed wall. Therefore, the difficulty of installing a single wall panel unit is less than the difficulty of directly installing the entire enclosed wall, thereby achieving the effect of reducing the difficulty of installing the enclosed wall.

[0013] In order to solve the problem of stability of each wall panel unit, the wall panel units are connected to each other.

[0014] In this solution, the wall panel units are connected to each other so that the upper side or the lower side of each wall panel unit is also fixed, making the installation of the wall panel units more stable.

[0015] Preferably, a connecting plate is provided between each of the wall panel units, and the connecting plate is connected to the wall panel units via fasteners, and one connecting plate is connected to two wall panel units.

[0016] In this solution, each wall panel unit is connected by a connecting plate, which is different from the connection between the wall panel units. After the connecting plate is fixed, the connecting plate can block the gap between the wall panel units, preventing foreign dust and other substances from entering through the gap between the wall panel units.

[0017] Preferably, the wall panel unit is provided with fixing holes, the side walls of the cabin are provided with screw holes corresponding to the positions of the fixing holes, and the wall panel unit is connected to the closed wall via fasteners.

[0018] In this solution, since the wall panel unit does not need to be opened frequently, the wall panel unit can be made more stable by fixing it with fasteners.

[0019] When the enclosed wall is installed on the side wall of the cabin, a depression is formed on the inner side of the side wall of the cabin, which makes it inconvenient to install the protective fireproof layer. In order to solve the problem that the enclosed wall cannot play the role of thermal insulation and fire prevention, a hanging plate is provided on the inner side of the side wall of the cabin. The hanging plate is connected to the side wall of the cabin, and the hanging plate is used to close the inspection opening from the inside.

[0020] In this solution, a hanging plate is provided on the inner side of the inspection opening. After the hanging plate is installed, the inner wall of the cabin can be made smoother, thereby facilitating the installation of fireproofing and thermal insulation materials.

[0021] Preferably, the hanging plate includes a side hanging plate and a main hanging plate, the side hanging plate is connected to the side wall of the cabin, and the main hanging plate is connected to the side hanging plate.

[0022] In this solution, the panels are divided into side panels and main panels. The main panels are connected to the side panels on either side. When equipment needs to be placed into the prefabricated cabin, the main panels need to be removed. Because the main panels are connected to the side panels, installation and removal of the main panels are performed relative to the side panels. This prevents the cabin's sidewalls from being weakened and deformed by removing and installing both the inward and outward sides.

[0023] Preferably, the prefabricated cabin includes a plurality of main hanging panels, and the plurality of main hanging panels are arranged in an up-down direction.

[0024] In this solution, multiple main hanging panels are provided, which can reduce the size and weight of the main hanging panels and facilitate installation and removal.

[0025] Preferably, side hanging plates are respectively provided on both sides of the inspection opening, and both sides of the main hanging plate are respectively connected to the side hanging plates.

[0026] In this solution, both sides of the main hanging plate are connected to the side hanging plates respectively, which can improve the stability of the installation.

[0027] Beneficial effects of the utility model:

[0028] The utility model provides an inspection opening on the side of the prefabricated cabin, and is provided with a detachable closing wall at the inspection opening. When it is necessary to transfer equipment into the prefabricated cabin, the closing wall can be disassembled to open the inspection opening, and the equipment can be transported into the prefabricated cabin from the side, thereby solving the problem of damage to the waterproof performance due to removal of the top cover.

[0036] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely explained through the specific implementation methods of the embodiments of the present invention.

[0037] Example 1:

[0038] like Figure 1 As shown, the first embodiment of the present invention provides a prefabricated cabin that is convenient for phased construction, including a cabin body, the cabin body including four side walls 1, one side wall 1 of the cabin body is provided with an inspection opening, and external equipment can enter the prefabricated cabin from the inspection opening. When construction is not required, the inspection opening is provided with a closed wall, and the inspection opening is blocked by the closed wall. When it is necessary to transfer equipment into the prefabricated cabin, the closed wall is removed, and then the equipment can be transferred from the inspection opening to the prefabricated cabin by a forklift. The closed wall closes the inspection opening from the outer side of the cabin body, and the closed opening is detachably connected to the side wall 1 of the cabin body by bolts.

[0039] The cabin body of the prefabricated cabin includes a frame, the frame is provided with through holes or screw holes, and the closed wall is detachably connected to the frame by bolts.

[0040] The enclosure wall completely encloses the inspection opening, which is the same height as the sidewall 1 of the cabin. The enclosure wall can include multiple wall panel units 2, which together form the enclosure wall. During installation, the multiple wall panel units 2 can be installed separately. The size and weight of the wall panel units 2 are both smaller than those of the enclosure wall, making installation easier than directly installing the entire enclosure wall.

[0041] The wall panel units 2 are arranged in the up-down direction, and the wall panel units 2 can also be arranged in the horizontal direction.

[0042] The preferred installation method is to arrange the wall panel units 2 in an up-and-down direction. If the wall panel units 2 are arranged in a left-and-right direction, the installer must secure the top and bottom of the wall panel units 2 separately during installation, requiring constant up-and-down movement, which is inconvenient. However, when the wall panel units 2 are arranged in an up-and-down direction, the installer only needs to secure the two sides of the wall panel units 2 separately, eliminating the need for up-and-down movement, making installation more convenient.

[0043] After the wall panel units 2 are fixed, gaps between them may form due to assembly precision, allowing dust to easily enter the prefabricated cabin through these gaps. To address this issue, using the example of vertically arranged wall panel units 2, the upper and lower edges of the wall panel units 2 overlap, eliminating the gaps through overlapping coverage.

[0044] When the wall panel units 2 are overlapped to eliminate gaps, mutually staggered step structures can be set at the overlapping parts of the wall panel units 2. After the wall panel units 2 are fixed, the steps between the two wall panel units 2 are located on the inner and outer sides respectively, eliminating the gaps between the wall panel units 2 and making the outer surfaces of the wall panel units 2 flush.

[0045] like Figure 2 As shown, the wall panel unit 2 is provided with a positioning groove, and the connecting plate 3 is provided with a waterproof ridge 4. The waterproof ridge 4 snaps into the positioning groove, forming a watertight seal between the connecting plate 3 and the wall panel unit 2. The waterproof ridge is preferably a deformable strip structure such as a rubber strip or silicone strip, and the waterproof ridge 4 is slightly larger than the positioning groove. When the waterproof ridge 4 snaps into the positioning groove, the waterproof ridge is squeezed, forcing the waterproof ridge 4 to fit snugly against the positioning groove, thus achieving a watertight seal between the connecting plate 3 and the wall panel unit 2.

[0046] Optionally, the entire connecting plate 3 may be made of rubber material, that is, the connecting plate 3 is a rubber plate.

[0047] Another approach to eliminating gaps between wall panel units 2 is to install a connecting plate 3 at the junction of two wall panel units 2. Connecting plate 3 is connected to the two wall panel units 2 via fasteners. Connecting plate 3 covers the gap between the wall panel units 2, effectively blocking the gap. With connecting plate 3 blocking the gap, dust and other impurities cannot directly enter the gap, effectively preventing dust from entering the gap between the wall panel units 2. Once connected, connecting plate 3 supports the wall panel units 2, making the installation of the wall panel units 2 more stable.

[0048] The wall panel units 2 and the connecting panels 3 are both rectangular panels.

[0049] The wall panel unit 2 is fixed to the outer side of the cabin body by bolts, and the connecting plate 3 is fixed to the outer side of the wall panel unit 2 by bolts.

[0050] Example 2:

[0051] The second embodiment provides a prefabricated cabin that is convenient for phased construction. Unlike the first embodiment, a hanging plate is further provided on the inner side of the inspection opening of the second embodiment.

[0052] The hanging plate is fixed to the inner side of the inspection opening, and the hanging plate is connected to the side wall 1 of the cabin through fasteners.

[0053] The installation of the hanging plate is used to make the inner side of the cabin smoother. After the hanging plate is set, a fireproof layer or a thermal insulation layer can be installed on the surface of the hanging plate.

[0054] like Figure 3As shown, the panels include side panels 5 and a main panel 6. The side panels 5 are positioned on either side of the access opening and connected to the sidewall 1 of the cabin. The main panel 6 is connected to the side panels 5 on either side. Because the side panels 5 are positioned on either side of the access opening, they do not obstruct it. When transferring equipment into the prefabricated cabin, the side panels 5 do not need to be removed; only the main panel 6 connected to them needs to be removed. When removing and installing the main panel 6, there is no need to remove fasteners from the cabin's sidewall 1, minimizing damage to the sidewall 1.

[0055] like Figure 4 As shown, one side panel 5 is attached to the inner sidewall 1 of the prefabricated cabin. At the same time, the side panel 5 that is attached to the inner sidewall 1 is also connected to the main panel 6. Therefore, the main panel 6 and the inner sidewall 1 of the prefabricated cabin are connected on the same surface as the side panel 5, so that the main panel 6 and the inner sidewall 1 of the prefabricated cabin are located in the same plane. Therefore, except for the protrusion formed by the side panel 5 on the inner sidewall 1 of the prefabricated cabin, the main panel 6 is flush with the inner side surface of the prefabricated cabin, ensuring that the inner side surface of the prefabricated cabin remains substantially flat, facilitating the renovation of the inner sidewall 1 of the prefabricated cabin.

[0056] Screws can be set on the side hanging plate 5, and through holes can be set on both sides of the main hanging plate 6. The through holes are used to cooperate with the screws. The main hanging plate 6 is hung on the screws through the through holes, and then the main plate and the side hanging plate 5 can be fixedly connected by the nuts and screws.

[0057] There can be multiple main hanging plates 6, for example, two, three, four or more main hanging plates 6. Providing multiple main hanging plates 6 can reduce the size and weight of the main hanging plates 6 and make installation easier.

[0058] Each main hanging plate 6 is mounted on the side hanging plate 5 in the up-down direction.
