Description

Technical Field

[0001] This utility model relates to the field of prefabricated cabins, and specifically provides a prefabricated cabin maintenance door and a prefabricated cabin. Background Technology

[0002] Currently, most prefabricated modular substations in China are single-layer or double-layer structures. For switchgear housed inside these compartments, if equipment needs to be replaced later, or if switchgear is added during project development, the common practice is to remove the existing top cover to move the cabinet into the prefabricated compartment, followed by restoring the top cover and performing waterproofing work. This results in significant waste of labor costs, and conventional doors severely compromise the overall waterproofing performance of the compartment. Therefore, there is an urgent need for a design that ensures the performance of the prefabricated compartment while facilitating the movement of switchgear in and out. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an inspection door for prefabricated cabins. While ensuring the waterproofing and sound insulation performance of the prefabricated cabins, it facilitates the removal or placement of switchgear, reducing labor intensity and saving costs. The specific technical solution is as follows:

[0004] A prefabricated cabin maintenance door includes an installation frame and a door body. The door body includes an outer door layer, a medium-strength layer and an inner protective layer from the outside to the inside. The installation frame is arranged around the door body and is fixedly connected to the wall of the prefabricated cabin. The door body is detachably connected to the installation frame.

[0005] In this scheme, the mounting frame is fixedly installed on the wall of the prefabricated compartment as a connecting structure, and a detachable door is provided to ensure that the door can be directly disassembled when needed, so as to provide an opening for easy placement or removal of the switch cabinet from the prefabricated compartment; at the same time, the multi-layer door structure can effectively ensure that the disassembly and installation of the door will not damage the complete protective performance of the prefabricated compartment.

[0006] After the inspection door is installed, it is necessary to ensure the strength of the prefabricated cabin wall. For this purpose, the medium strength layer preferably includes a vertical frame and a horizontal frame. The two ends of the vertical frame are detachably connected to the upper and lower sides of the installation frame, and the horizontal frame is detachably connected to the left and right sides of the installation frame.

[0007] In this design, vertical supports provide vertical support to the frame, while horizontal supports provide horizontal support to ensure the strength and reliability of the inspection door on the prefabricated cabin wall.

[0008] Preferably, the outer door layer includes an outer door frame and an outer door panel. The outer door frame is a rectangular frame, and the outer door panel is embedded in the door frame. The outer door panel is detachably connected to the vertical frame and / or the horizontal frame.

[0009] In this design, since the outer door layer is located at the outermost edge of the prefabricated cabin and is in contact with the outside world, the outer door layer is set up as two independent parts: the outer door frame and the outer door panel. This ensures the airtightness of the outer door layer by maintaining the outer door frame, and if the outer door layer is scratched, impacted, or otherwise damaged, the outer door panel can be directly replaced to ensure the integrity of the maintenance door.

[0010] Preferably, a sealing strip is provided between the outer door frame and the outer door panel.

[0011] Preferably, the size of the outer door frame is adapted to the mounting frame, and the outer door frame is bolted to the mounting frame.

[0012] Preferably, the outer door panel surface is provided with diatomaceous earth, which can improve the aesthetics of the inspection door, enhance the fire resistance and flame retardancy of the door, and also increase the sound absorption, noise reduction, and heat insulation capabilities of the outer door panel.

[0013] Preferably, the inner protective layer includes a rock wool board and a pressure plate that connects the rock wool board to the intermediate strength layer.

[0014] In this solution, rock wool boards have good sound absorption and flame retardancy, as well as water repellency and moisture resistance, which can effectively prevent the prefabricated cabin from becoming damp; and rock wool boards can be quickly installed and removed by pressure plates.

[0015] Preferably, the pressure plate has a "T" shaped cross-section and is detachably connected to the mounting frame. The pressure plate presses down on the edge of the rock wool board, allowing the rock wool board to abut against the surface of the medium-strength layer.

[0016] A prefabricated cabin is provided with the aforementioned prefabricated cabin inspection door, the height of which is the same as the height of the prefabricated cabin wall, so as to ensure that the prefabricated cabin has an opening of sufficient size for the switch cabinet to pass through.

[0017] The beneficial effects of this utility model are:

[0018] This utility model uses an installation frame as a connecting structure to be fixedly installed on the wall of the prefabricated compartment, and provides a detachable door to ensure that the door can be directly disassembled when needed, providing an opening for easy insertion or removal of the switch cabinet from the prefabricated compartment; at the same time, the multi-layered door structure can effectively ensure the strength of the prefabricated compartment wall and ensure that the disassembly and installation of the door will not damage the complete protective performance of the prefabricated compartment, reducing the labor intensity of workers and also reducing installation costs.

[0025] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of this utility model.

[0026] Example 1:

[0027] A type of prefabricated cabin access door, such as Figures 1 to 3 As shown, the system includes a mounting frame 1 and a door. The door, from the outside to the inside, comprises an outer door layer 2, a medium-strength layer 3, and an inner protective layer 4. The mounting frame 1 surrounds the door and is fixedly connected to the wall 5 of the prefabricated compartment. The door is detachably connected to the mounting frame 1. The two-layer structure of the outer door layer 2 and the inner protective layer 4 ensures the waterproofness, sound insulation, flame retardancy, and thermal insulation of the inspection door. The medium-strength layer 3 ensures the overall strength and reliability of the inspection door after installation. In this embodiment, the mounting frame 1 is fixedly installed on the wall 5 of the prefabricated compartment as a connecting structure. The detachable door allows for direct disassembly when needed, providing an opening for easy insertion or removal of the switchgear from the prefabricated compartment. Simultaneously, the multi-layered door structure effectively ensures that the disassembly and installation of the door do not compromise the complete protective performance of the prefabricated compartment.

[0028] The outer door layer 2 includes an outer door frame 201 and an outer door panel 202. The outer door frame 201 is a rectangular frame with grooves. The outer door panel 202 is embedded in the grooves of the door frame. The outer door panel 202 is detachably connected to the vertical frame 301 and / or the horizontal frame 302. Specifically, the outer door panel 202 is provided with bolt holes that are compatible with the vertical frame 301 or the horizontal frame 302. The detachable connection means that the outer door panel 202 is directly connected to the intermediate strength layer 3 by bolts. Of course, other detachable connection structures can also be used, such as the outer door panel 202 being snapped together with the horizontal frame 302 or the vertical frame 301 by matching buckles, or the two being connected by pins with matching holes. The preferred detachable connection is a bolt connection. Of course, the size of the outer door frame 201 shown is adapted to the mounting frame 1, and the outer door frame 201 can also be installed on the mounting frame 1 by bolt connection, which improves the installation stability of the outer door frame 201 and also makes it easier to connect the outer door panel 202 and the medium strength layer 3.

[0029] Furthermore, since the outer door layer 2 is located at the outermost edge of the prefabricated cabin and is in contact with the outside world, it is configured as two independent parts: the outer door frame 201 and the outer door panel 202. This ensures the airtightness of the outer door layer 2 within the outer door frame 201. Simultaneously, if the outer door layer 2 is damaged by scratches, impacts, or other means, the outer door panel 202 can be directly replaced to ensure the integrity of the access door. A sealing strip is also provided between the outer door frame 201 and the outer door panel 202.

[0030] Furthermore, the surface of the outer door panel 202 is provided with diatomaceous earth, which not only improves the aesthetics of the inspection door but also enhances the fire resistance and flame retardancy of the door body, while also increasing the sound absorption, noise reduction, and heat insulation capabilities of the outer door panel 202.

[0031] Example 2:

[0032] Based on Example 1, after installing the inspection door, it is necessary to ensure the strength of the prefabricated cabin wall 5, such as... Figures 1 to 3 As shown, the medium-strength layer 3 provided in this embodiment includes a vertical frame 301 and a horizontal frame 302. The two ends of the vertical frame 301 are detachably connected to the upper and lower sides of the mounting frame 1, and the horizontal frame 302 is detachably connected to the left and right sides of the mounting frame 1.

[0033] In this design, the vertical frame 301 provides vertical support to the frame, and the horizontal frame 302 provides horizontal support. Connecting plates are installed at both ends of the vertical frame 301, which is then bolted to the mounting frame 1. Similarly, connecting plates are also installed at both ends of the horizontal frame 302 for bolting to either the vertical frame 301 or the mounting frame 1. This ensures that the intermediate strength layer 3 is removable while maintaining reliable strength at the inspection door on the prefabricated cabin wall. Alternatively, the vertical frame 301 and the horizontal frame 302 can also be interlocked and secured using suitable clips.

[0034] Furthermore, to ensure the performance of the prefabricated cabin walls, the inner protective layer 4 includes rock wool boards 401 and pressure plates 402 that connect the rock wool boards 401 to the intermediate strength layer 3. The rock wool boards 401 have good sound absorption and flame retardant properties, as well as water repellency and moisture resistance, which can effectively prevent the prefabricated cabin from becoming damp; while the pressure plates 402 allow for quick installation and removal of the rock wool boards 401.

[0035] The pressure plate 402 has a T-shaped cross-section and is detachably connected to the mounting frame 1, preferably by bolts. The pressure plate 402 presses down on the edge of the rock wool board 401, allowing the rock wool board 401 to abut against the surface of the medium-strength layer 3.

[0036] Example 3:

[0037] A prefabricated cabin includes a prefabricated cabin inspection door as described in the above embodiments. The height of the prefabricated cabin inspection door is the same as the height of the wall 5 of the prefabricated cabin, so as to ensure that the prefabricated cabin has an opening of sufficient size for the switch cabinet to pass through.

[0038] Whether it is a single-layer or double-layer prefabricated cabin with a three-dimensional station, this maintenance door can be used to quickly put in or move out the low-voltage cabinet without disassembling the cabin cover or damaging the overall waterproof performance of the cabin. When the switch cabinet needs to be put in, simply remove the inner protective layer 4, the outer door layer 2 and the medium strength layer 3 from the inside out to "open" the maintenance door. When "closing" the maintenance door, first install the medium strength layer 3, then install the outer door layer 2, and finally install the inner protective layer 4.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
