[0033] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are merely for explaining the related application and are not intended to limit the application. The described embodiments are merely a portion of the embodiments of the present application and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in the present application without creative effort are intended to fall within the scope of protection of the present application.

[0034] As described in the background technology, the current fireproof performance of corrugated color steel plates is relatively low, and there are certain safety hazards. Therefore, the present application provides a firewall 10, which can be assembled from firewall monomers 100. Considering the reliability requirements of the firewall 10 in the container structure, the sealing between the firewall monomers 100 is also a technical problem that needs to be solved. In order to facilitate the understanding of the technical solution, the present application first introduces the structure of the firewall monomer 100. The firewall monomer 100 has a relative first side 100a and a second side 100b, as well as a third side 100c and a fourth side 100d, wherein the first side 100a and the second side 100b, as well as the third side 100c and the fourth side 100d are located on the side of the plate surface, such as Figure 1 and Figure 2 The firewall unit 100 is usually joined together by side surfaces.

[0035] The fire wall unit 100 includes outer panels 110 arranged in opposite directions and a fireproof filling layer 120 interposed between the outer panels 110. The outer panels 110 are the hardware components of the fire wall unit 100, supporting the entire unit 100. For example, the outer panels 110 include a glass magnesium plate 112 and a color-coated steel plate 111 arranged from the inside out. The fireproof filling layer 120 is made of thermal insulation, such as a rock wool filling layer. The fire wall unit 100 has a five-layer sandwich structure, with the outermost color-coated steel plate 111 being 0.5 mm thick and the inner glass magnesium plate 112 being 5 mm thick. The color-coated steel plate 111 serves to enhance strength, the glass magnesium plate 112 serves to provide flame retardancy and fire resistance, and the rock wool serves to provide thermal insulation.

[0036] See also Figures 3 to 8 The firewall 10 in the example of the present application includes at least one firewall unit 100, wherein the sides of two adjacent firewall units 100 can be spliced ​​by a mortise and tenon structure.

[0037] The firewall 10 of the present application includes at least one firewall unit 100, and during assembly, two adjacent firewall units 100 can be connected via a mortise and tenon structure. This ensures a more secure interlocking of the two adjacent firewall units 100, effectively reducing the risk of cracking at high-temperature joints. This improves the fireproofing performance of the firewall structure and, when installed in electrical equipment, contributes to improved safety. Furthermore, since the firewall units 100 are connected using a mortise and tenon structure, they are easier to standardize, reducing assembly time. Furthermore, the firewall units 100 of this structure are resistant to deformation at high temperatures.

[0038] It should be noted that the mortise and tenon structure includes a convex part and a concave part, and the convex part and the concave part are spliced ​​to form a splicing surface. Since the above-mentioned splicing surface is not a straight line at the profile line 130 of the preset cross section (but can be a shape composed of multiple straight lines), the sealing performance at the splicing surface can be improved. The above-mentioned preset cross section is parallel to the splicing direction, and the preset cross section can be any cross section between the first side 100a and the second side 100b. Further, the preset cross section is perpendicular to the first side 100a and the second side 100b, or parallel to the third side 100c and the fourth side 100d. Among them, the splicing direction can be understood as the direction in which the multiple firewall units 100 are arranged as a whole. Figure 3 , the splicing direction is the direction corresponding to the left and right.

[0039] Figures 4 to 7 The above-mentioned profile line 130 is shown as a straight line. Figure 8 The profile 130 shown is a curved type. The above-mentioned distinction between straight and curved types is determined only by the form of the segments that make up the profile 130. If it is composed of several straight segments, it can be understood as a straight type; if it is composed of several curved segments, it can be understood as a curved type; if it is composed of several straight segments and several curved segments, it can be understood as a curved type. Extensive examples are not given here.

[0040] The above description is based on the classification of the profile 130. Specifically, the profile 130 includes a convex line segment 132 and a concave line segment 131. The convex line segment 132 is constructed to be away from the concave line segment 131. Among them, the convex line segment 132 is mainly formed by the cooperation of the convex part and the concave part, while the concave line segment 131 is mainly formed by the cooperation of the area other than the concave part and the convex part on the side. The multiple convex line segments 132 are constructed into any one of a rectangular structure and a trapezoidal structure or a combination of any two. This application also lists several structural forms of the convex line segments 132. Figure 4 The convex line segment 132 is composed of two rectangular structures. Figure 6 The convex line segment 132 is composed of a rectangular structure. Figure 7 The middle convex line segment 132 is composed of a rectangular structure, and a plurality of rectangular structures are arranged side by side.

[0041] In some examples, the firewall 10 includes a single firewall unit 100, i.e., all firewall units 100 have the same structure (which can be understood as a standard unit). The first and third sides 100a, 100c of each firewall unit 100 are provided with convex portions, and the second and fourth sides 100b, 100d are provided with concave portions. The convex portion of the first side 100a of the center firewall unit 100 is spliced ​​with the concave portion of the second side 100b of the left firewall unit 100, the concave portion of the second side 100b of the center firewall unit 100 is spliced ​​with the convex portion of the first side 100a of the right firewall unit 100, the convex portion of the third side 100c of the center firewall unit 100 is spliced ​​with the concave portion of the fourth side 100d of the lower firewall unit 100, and the concave portion of the fourth side 100d of the center firewall unit 100 is spliced ​​with the convex portion of the third side 100c of the upper firewall unit 100. It meets the needs of rapid design, is easy to install, and relies on its own fastening to improve the production efficiency of the production line.

[0042] In some examples, the firewall 10 includes two firewall units 100 having opposite sides, namely a first firewall unit 100 and a second firewall unit 100. The first side 100a of the first firewall unit 100 is provided with a convex portion, and the second side 100b of the second firewall unit 100 is provided with a concave portion. Figures 3 to 8 shown.

[0043] In some examples, the firewall 10 includes three firewall units 100 having opposite side surfaces, namely a first firewall unit 100, a second firewall unit 100, and a third firewall unit 100. The first firewall unit 100, the second firewall unit 100, and the third firewall unit 100 have opposite first side surfaces 100a and second side surfaces 100b. The first side surfaces 100a of the first firewall unit 100 and the first side surfaces 100a of the third firewall unit 100 are both provided with convex portions, and the second side surfaces 100b of the second firewall unit 100 and the second side surfaces 100b of the third firewall unit 100 are both provided with concave portions, as shown in FIG. Figures 9 and 10 Combine Figure 2 shown.

[0044] It should be noted that in the actual implementation process, the firewall layout is more often arranged in a spatial plane, that is, most of the four sides have concave and convex matching structures, which are assembled to form an entire firewall plane.

[0045] See also Figure 11In some examples of this application, a fire wall 10 structure for electrical equipment is specifically described. This fire wall 10 comprises eleven fire wall units 100 and two removable fire blocks 200. Nine of the fire wall units 100 are spliced ​​together on the top of the fire wall 10, two of the fire wall units 100 are arranged to the right of a connection hole 300, and two of the removable fire blocks 200 are arranged to the left of the connection hole 300. The connection hole 300 allows electrical equipment to pass through. The position of the connection hole 300 is determined by the layout of the electronic equipment within the electrical equipment and is not the focus of this application. The number and position of the removable fire blocks 200 are also adjusted according to actual needs.

[0046] In addition, since there is a possibility of cables passing through adjacent chambers, some firewall units 100 may have communication holes 400 for communication cables to pass through. The communication holes 400 can be prefabricated on some firewall units 100. After installation, the gaps between the cables, copper busbars, and their protective equipment and the firewall are coated with fire-retardant putty to ensure fireproof performance. The firewall is fastened to the container body by welding or bolts on all sides. To improve the operability of the equipment, a detachable fireproof block 200 is also provided on the firewall. It is connected and fixed to the original firewall body with bolts and can be removed during equipment installation for easy operation.

[0047] See also Figure 12 The present application provides an electrical device including any of the above-mentioned firewalls 10. Since the above-mentioned firewall 10 has the above-mentioned effects, the electrical device including the firewall 10 should also have corresponding effects, which will not be described in detail here.

[0048] As an exemplary embodiment, the above-mentioned electrical equipment can be specifically but not limited to an integrated all-in-one machine, which includes a first inverter chamber 20, a transformer chamber 30, a second inverter chamber 40 and a ring network cabinet chamber 50. The above-mentioned first inverter chamber 20, transformer chamber 30, second inverter chamber 40 and ring network cabinet chamber 50 can all be understood as chambers arranged in sequence, and the firewall 10 is located between adjacent chambers.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.
