Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated explosion-proof compartments, specifically to a door panel structure for a prefabricated explosion-proof compartment and a prefabricated compartment. Background Technology

[0002] Prefabricated cabins are integrated and modular equipment cabins with features such as standardized design, factory prefabrication, and rapid on-site installation, playing an important role in multiple fields such as power, new energy, and industrial automation.

[0003] Currently, domestically produced prefabricated substations (box-type substations) are designed with explosion-proof fans in the explosion-proof compartments. The explosion-proof fans are only for air outlets, and there is also an air inlet structure to maintain the air pressure balance in the prefabricated compartment.

[0004] However, the existing air intake structure uses a louvered vent, which consists of multiple inclined blades. Air circulation is achieved through the gaps between the inclined blades. Furthermore, the existing air intake structure requires on-duty personnel to manually open it outdoors. If the air intake structure is not opened for a long time, it can easily cause negative pressure inside the cabin, making it difficult to open the cabin door. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems of wind and sand intrusion and negative pressure inside the cabin caused by the imperfect function of the air intake structure in the existing technology. It provides a door panel structure for the explosion-proof compartment of the prefabricated cabin, which can balance the air pressure inside and outside the prefabricated cabin by setting air inlets. The main concept is as follows:

[0006] A door panel structure for a prefabricated explosion-proof compartment includes a door panel body, a surrounding panel, and an air inlet. The door panel body comprises an inner door panel and an outer door panel, both of which have air inlets. The surrounding panel is located between the inner and outer door panels and is a closed structure connected end to end. The air inlet is located in the middle of the surrounding panel. This design features a double-layer door panel structure, which enhances the strength of the door panel. Furthermore, the air inlets on both the inner and outer door panels allow for continuous air circulation between the inside and outside of the prefabricated compartment.

[0007] Preferably, the door panel body has a plurality of surrounding panels, and the plurality of surrounding panels are connected to each other.

[0008] Preferably, the enclosure is circular, rectangular, or polygonal.

[0009] Preferably, the enclosure panel has a U-shaped structure, and includes a support portion and a first connecting portion and a second connecting portion respectively perpendicularly disposed on both sides of the support portion. The first connecting portion is connected to the inner wall of the inner door panel, and the second connecting portion is connected to the inner wall of the outer door panel. The support portion is used for isolation and support; and / or, the enclosure panel is connected to the inner door panel and the outer door panel by welding.

[0010] Preferably, the door panel body further includes a retaining edge, which is used to close the four sides of the inner door panel and the outer door panel.

[0011] Preferably, the inner door panel, outer door panel, side panel and enclosure panel form a sealed cavity, which is filled with a foaming agent.

[0012] The second aspect of this utility model aims to solve the technical problem that the air inlet easily carries sand and dust into the prefabricated cabin. Furthermore, the air inlet is equipped with a dustproof structure, which includes a mounting frame and a dustproof cover mounted on the mounting frame, with the mounting frame located on the outer door panel.

[0013] Preferably, a mounting section is formed between the enclosure and the air inlet, which is used to install the mounting bracket. A certain amount of slack is left between the enclosure and the air inlet so that this area is not filled with foaming agent. This area has a single-layer structure, which allows for better drilling and installation.

[0014] Preferably, a sealant is provided between the mounting bracket and the mounting part.

[0015] A prefabricated cabin, including a door panel structure for the explosion-proof compartment of the prefabricated cabin.

[0016] Preferably, it also includes an explosion-proof compartment, in which an explosion-proof fan is installed.

[0017] The beneficial effects of this utility model are as follows: the double-layer door panel structure improves the strength of the door panel, and the air inlets are opened on the inner and outer door panels to allow air to circulate inside and outside the prefabricated cabin. The enclosure panel surrounds the air inlets to prevent air from entering the gap between the inner and outer door panels. Attached Figure Description

[0025] Example 1

[0026] like Figures 1-3 As shown, the door panel structure of the prefabricated explosion-proof compartment provided in this embodiment includes a door panel body, a surrounding panel 4 and an air inlet 3. The door panel body includes an inner door panel 1 and an outer door panel 2. Both the inner door panel 1 and the outer door panel 2 are provided with air inlets 3. The surrounding panel 4 is disposed between the inner door panel 1 and the outer door panel 2. The surrounding panel 4 is a closed structure with the ends connected. The air inlet 3 is located in the middle of the surrounding panel 4.

[0027] This embodiment features a double-layer door panel structure, which enhances the strength of the door panel. Air inlets 3 are provided on the inner door panel 1 and the outer door panel 2, allowing air to circulate between the inside and outside of the prefabricated cabin. The enclosure panel 4 surrounds the air inlets 3 to prevent air from entering the gap between the inner door panel 1 and the outer door panel 2.

[0028] like Figure 1 As shown, in this embodiment, the air inlet 3 is a circular hole with a diameter of 250-300mm.

[0029] The door panel body is provided with a plurality of surrounding panels 4, which are connected to each other and form a circle, rectangle or polygon.

[0030] The enclosure 4 has a U-shaped structure and includes a support part and a first connecting part and a second connecting part respectively perpendicularly arranged on both sides of the support part. The first connecting part is connected to the inner wall of the inner door panel 1, and the second connecting part is connected to the inner wall of the outer door panel 2. The support part is used for isolation and support.

[0031] In this embodiment, the enclosure panel 4 is connected to the inner door panel 1 and the outer door panel 2 by welding.

[0032] In the actual installation process: First, the enclosure panel 4 is spot-welded to the inner door panel 1. Second, the outer door panel 2 and the inner door panel 1 are welded together. Finally, the enclosure panel 4 is spot-welded to the outer door panel 2. After the door panels are welded, they are sandblasted, painted and foamed.

[0033] The door panel body in this embodiment also includes a retaining edge 5, which is used to close the four sides of the inner door panel 1 and the outer door panel 2. In one embodiment, the retaining edge 5 is a sheet metal structure. After the surrounding panel 4 is welded and the distance between the inner door panel 1 and the outer door panel 2 is positioned, the retaining edge 5 is welded and closed along the inner door panel 1 and the outer door panel 2. In another embodiment, the retaining edge 5 is integrally formed with the inner door panel 1 or the outer door panel 2. A vertical angle is formed by bending the sheet metal parts, and the retaining edge 5 after bending the outer door panel 2 and the inner door panel 1 is interlocked and welded together.

[0034] The inner door panel 1, outer door panel 2, edge band 5, and surrounding panel 4 form a sealed cavity 6, which is filled with a foaming agent. In this embodiment, polyurethane foaming agent is used, enabling the door panel body to achieve fireproof and heat-insulating functions.

[0035] Example 2

[0036] like Figures 1-2 As shown, the air inlet 3 in this embodiment is equipped with a dustproof structure. The dustproof mechanism includes a mounting frame 8 and a dust cover 9 disposed on the mounting frame 8. The mounting frame 8 is disposed on the outer door panel 2.

[0037] The mounting section 7 is formed between the enclosure 4 and the air inlet 3, and the mounting section 7 is used to install the mounting bracket 8. A certain amount of slack is left between the enclosure 4 and the air inlet 3 so that this area is not filled with foaming agent. This area has a single-layer structure, which allows for better drilling and installation.

[0038] In this embodiment, the dust cover 9 is fastened between the mounting bracket 8 and the outer door panel 2. The dust cover 9 also has through holes corresponding to the mounting positions of the fastening bolts on the mounting bracket 8 and the outer door panel 2, allowing the fastening bolts to pass through the mounting bracket 8, the dust cover 9, and the outer door panel 2 simultaneously, thus achieving a secure installation of the dust cover 9. Sealant is applied between the mounting bracket 8 and the mounting portion 7 of the outer door panel 2, allowing the contact surfaces between the dust cover 9 and the outer door panel 2 to be waterproofed.

[0039] While installing the mounting bracket 8, install a filter of appropriate size between the filter mounting bracket 8 and the outer door panel 2 to prevent outdoor dust and flying insects from entering the cabin through the air inlet 3. Before installing the dust cover 9 between the dust cover 9 and the outer door panel 2, a sealing strip needs to be applied to the contact surface. After installation, apply a ring of sealant to the outer edge of the contact surface between the mounting bracket 8 and the outer door panel 2 for waterproofing.
