Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and specifically to a reinforcing member for power distribution cabinets. Background Technology

[0002] Existing distribution cabinets mostly use single-layer thin sheet structures for corner protectors, which have weak resistance to bending and compression. They are prone to denting and deformation after being subjected to force, making it difficult to effectively reinforce the corners of the cabinet. In addition, they lack insulation design, posing a risk of leakage and electric shock during the operation of the distribution cabinet.

[0003] Therefore, this utility model provides a reinforcing component for a power distribution cabinet. The base has a sandwiched layer with a welded filler plate featuring regular polygonal through-holes, which improves structural strength while achieving weight reduction. The outer wall is coated with an epoxy resin layer for rust and corrosion protection, and an adhesive silicone rubber insulating sleeve provides both insulation and impact resistance. This meets the power distribution cabinet industry's requirements for corner reinforcement components that resist bending and leakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a reinforcing component for a power distribution cabinet, comprising: a foot, wherein the foot is disposed at the corner of the power distribution cabinet, the inner wall of the foot has a sandwich layer, and the inner wall of the sandwich layer is welded with a filler plate; the filler plate has through holes; a protective sleeve is adhered to the outer wall of the foot; a connecting angle is fixedly connected to the outer wall of the foot; a connecting plate is fixed to the outer wall of the connecting angle by bolts; the connecting plate has at least two displacement holes; and one side of the outer wall of the foot has a concave angle. In use, this reinforcing component for a power distribution cabinet uses the foot as the core component, with its three sides perpendicular to each other, allowing it to fit snugly against the corner of the power distribution cabinet, ensuring compatibility with the cabinet structure. Both the foot protector and the connecting plate conform to the national standard for distribution cabinet dimensions, ensuring compatibility with different specifications of national standard distribution cabinets from the design stage, eliminating any unusable issues. The inner wall of the foot protector has a sandwich panel welded to it, with regular polygonal through-holes linearly arrayed along its length, width, and height. This hollow design achieves lightweighting while maintaining support strength through the array structure, effectively avoiding the deformation defects of traditional single-layer corner protector structures. Furthermore, the outer wall of the foot protector is coated with an epoxy resin coating. This coating has excellent adhesion and chemical stability, forming a dense protective film on the surface of the foot protector, isolating it from air, moisture, and corrosive substances, significantly improving the rust and corrosion resistance of the foot protector and extending the overall service life of the reinforcing components.

[0005] Preferably, the outer wall of the foot is coated with an anti-rust and anti-corrosion coating, the protective sleeve is made of elastic insulating material, the through holes are linearly arrayed along the length of the connecting plate, and the connecting plate is made of triangular steel. The core reason for choosing triangular steel is that its unique triangular structure has extremely strong mechanical stability. Compared with flat plates or other shaped connectors, triangular steel can evenly distribute the external forces transmitted by the connection angle, such as the cabinet load and the fastening force during installation, to its three sides. This is beneficial to improving bending resistance and load-bearing performance, ensuring the stability of the connection between the foot and the cabinet, and avoiding failure of reinforcement due to loosening of the connection during long-term use. At the same time, triangular steel has high strength and controllable cost, which is suitable for the stress requirements of long-term use of the distribution cabinet. Combined with at least two displacement holes opened on the connecting plate, the bolt fixing position can be adjusted according to the actual installation requirements, further enhancing the compatibility with national standard distribution cabinets, and eliminating the need to customize components due to slight differences in cabinet dimensions.

[0006] Preferably, the connecting corner and connecting plate are triangular steel in shape, the through holes are regular polygons, and the through holes are linearly arrayed along the length, width, and height directions of the outer wall of the filling plate. The protective sleeve bonded to the outer wall of the foot is made of silicone rubber. Silicone rubber not only has excellent elasticity, which can buffer accidental impact forces during the handling and use of the distribution cabinet, and prevent paint peeling and deformation due to hard contact between the foot and the cabinet corners, while protecting operators from bumps and injuries, but also has excellent insulation properties, which helps to isolate the foot from the external conductive path, fundamentally eliminating the risk of leakage and electric shock that may exist in the operation of the distribution cabinet. Compared with the traditional metal corner without insulation design, the safety is greatly improved. Moreover, silicone rubber is resistant to high and low temperatures and aging, and can adapt to different indoor and outdoor use environments of the distribution cabinet. It is not easy to crack or fail after long-term use, and forms a synergistic protection with the epoxy resin coating on the outer wall of the foot, further ensuring the durability of the reinforcement.

[0007] Preferably, the foot has three sides, which are perpendicular to each other. The outer walls at the perpendicular intersections are all fixedly connected with connecting corners. The concave angle is larger than the cabinet door corner of the distribution cabinet, which facilitates the opening and closing of the cabinet door. The entire reinforcement is optimized in all aspects through the synergistic effect of each component. The concave angle design of the foot, because the angle is larger than the cabinet door corner of the distribution cabinet, can reserve sufficient space for the cabinet door to rotate, avoiding the problem of the corner of the foot blocking the cabinet door and causing obstruction of opening and closing, thus ensuring ease of use. From the epoxy resin anti-rust coating and silicone rubber insulating protective sleeve of the foot to the stable structure of the triangular steel connecting plate, and the size design that meets national standards, the corners of the distribution cabinet are effectively reinforced, which is conducive to meeting the use requirements of national standard distribution cabinets and reducing obstacles to use.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model features a foot cover with three perpendicular sides that fit snugly against the corners of the electrical distribution cabinet. The inner wall of the foot cover is reinforced with a filler plate with regular polygonal through holes, achieving lightweight design while enhancing support rigidity and avoiding the deformation problem of traditional single-layer corner covers. The outer wall of the foot cover is coated with an anti-rust and anti-corrosion coating and is also bonded with an elastic insulating protective sleeve made of silicone rubber, which can isolate corrosion, buffer impacts, and prevent the risk of leakage.

[0010] 2. This utility model features a foot protector and a connecting plate, both of which conform to the dimensions of national standard distribution cabinets, eliminating concerns about compatibility. The connecting plate is made of triangular steel, combining high strength and stability. Its displacement holes can be used to adjust the bolt fixing position, adapting to different cabinet specifications. The concave angle on one side of the foot protector is larger than the cabinet door corner, allowing for cabinet door rotation space and preventing the foot protector from obstructing the cabinet door.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] Example:

[0018] Please see Figure 1 - Figure 4This utility model provides a technical solution: a reinforcing member for a power distribution cabinet, comprising: a foot 1, the foot 1 being disposed at the corner of the power distribution cabinet, the inner wall of the foot 1 having a sandwich layer, the inner wall of the sandwich layer being welded with a filling plate 2; the filling plate 2 having a through hole 3, the outer wall of the foot 1 being bonded with a protective sleeve 4, the outer wall of the foot 1 being fixedly connected with a connecting angle 5, the outer wall of the connecting angle 5 being fixed with a connecting plate 7 by bolts 6, the connecting plate 7 having at least two displacement holes 8, and one side of the outer wall of the foot 1 having an inward concave angle 9.

[0019] The outer wall of the foot 1 is coated with an anti-rust and anti-corrosion coating. The protective sleeve 4 is made of elastic insulating material. The through holes 3 are distributed in a linear array along the length of the connecting plate 7. The connecting angle 5 and the connecting plate 7 are both triangular steel in shape. The through holes 3 are regular polygons. The through holes 3 are distributed in a linear array along the length, width and height of the outer wall of the filling plate 2. The foot 1 has three faces, which are perpendicular to each other. The outer walls at the perpendicular intersections are all fixedly connected with connecting angles 5. The concave angle 9 is larger than the cabinet door angle of the distribution cabinet, which facilitates the opening and closing of the cabinet door.

[0020] Working principle:

[0021] In use, the reinforcing component of this distribution cabinet uses the base 1 as the core component. Its three sides are perpendicular to each other, which can fit the corners of the distribution cabinet to ensure compatibility with the cabinet structure. At the same time, both the base 1 and the connecting plate 7 comply with the national standard distribution cabinet size standard, which helps to ensure compatibility with different specifications of national standard distribution cabinets from the design source, and there is no problem of incompatibility. The inner wall of the base 1 has a sandwich layer welded with a filling plate 2. The regular polygonal through holes 3 on the filling plate 2 are linearly arrayed along the length, width and height directions. The hollow design achieves weight reduction, and the array structure maintains the supporting strength, effectively avoiding the defects of traditional single-layer corner structure that is easy to deform. In addition, the outer wall of the base 1 is coated with an epoxy resin coating. This coating has excellent adhesion and chemical stability and can form a dense protective film on the surface of the base 1, which isolates air, moisture and corrosive substances, significantly improves the rust and corrosion resistance of the base 1, and extends the overall service life of the reinforcing component.

[0022] The connecting plate 7 is made of triangular steel. The core reason for choosing triangular steel is that its unique triangular structure has extremely strong mechanical stability. Compared with flat plates or other shaped connectors, triangular steel can evenly distribute the external forces transmitted by the connecting angle 5, such as the cabinet load and the tightening force during installation, to its three sides. This is beneficial to improving bending resistance and load-bearing performance, ensuring the stability of the connection between the foot 1 and the cabinet, and avoiding failure of reinforcement due to loosening of the connection during long-term use. At the same time, triangular steel has high strength and controllable cost, which is suitable for the stress requirements of long-term use of the distribution cabinet. Combined with at least two displacement holes 8 on the connecting plate 7, the fixing position of the bolts 6 can be adjusted according to the actual installation requirements, further enhancing the compatibility with national standard distribution cabinets, and eliminating the need to customize parts due to slight differences in cabinet dimensions.

[0023] The protective sleeve 4, which is bonded to the outer wall of the foot protector 1, is made of silicone rubber. Silicone rubber not only has excellent elasticity, which can buffer accidental impact forces during the handling and use of the distribution cabinet, preventing paint peeling and deformation caused by hard contact between the foot protector 1 and the cabinet corners, and protecting operators from bumps and injuries, but also has excellent insulation properties, which helps to isolate the foot protector 1 from external conductive paths, fundamentally eliminating the risk of leakage and electric shock that may exist during the operation of the distribution cabinet. Compared with traditional metal corner protectors without insulation design, safety is greatly improved. Moreover, silicone rubber is resistant to high and low temperatures and aging, and can adapt to different indoor and outdoor operating environments of the distribution cabinet. It is not easy to crack or fail after long-term use. It forms a synergistic protection with the epoxy resin coating on the outer wall of the foot protector 1, further ensuring the durability of the reinforcement.

[0024] The entire reinforcement system achieves comprehensive optimization through the synergistic effect of its components. The concave angle 9 of the foot 1, being larger than the angle of the cabinet door, provides ample space for the cabinet door to rotate, preventing the corner from obstructing the door and ensuring ease of use. From the epoxy resin anti-rust coating and silicone rubber insulating protective sleeve 4 of the foot 1 to the stable structure of the triangular steel connecting plate 7 and the standard-compliant dimensions, the system effectively strengthens the corners of the cabinet, meeting the requirements of standard cabinets and reducing obstacles to use.
