Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinet structures, and specifically relates to an internal frame for an electrical cabinet. Background Technique

[0002] An electrical cabinet is a commonly used outer shell of electrical equipment in the power system. According to the electrical wiring requirements, relevant control system components are assembled in a closed or semi-closed metal box. The structural design of the electrical cabinet should meet the basic requirements for normal operation. Low-voltage cabinets, high-voltage cabinets, and PLC control cabinets are sometimes indoors or outdoors, and have higher requirements for the cabinet structure, such as structural strength, waterproofing, dustproofing, and salt spray resistance, so as to avoid changes in the surrounding environment of the electrical cabinet and ensure the normal and stable operation of the internal components of the electrical cabinet.

[0003] In the manufacture of existing electrical control cabinets by users, the sealing performance of the internal frame for installation is not good, resulting in a reduction in the sealing failure time, a reduction in the service life of electrical components, and an increase in maintenance costs. In the manufacture of existing electrical control cabinets by users, the frame strength does not meet the required actual requirements, and there are limitations in the processing of the frame thickness, resulting in low strength and an increase in the risk of equipment safety.

[0024] Embodiment

[0025] Refer to Figures 1-4, this technical solution provides an internal frame for an electrical cabinet, which includes an internal frame 11. The internal frame 11 includes vertical columns 1, bottom crossbeams 2, longitudinal beams 3, depth crossbeams 4, left seven-ways 10, right seven-ways 9, L-shaped fixing parts 5, side plate fixing parts 6, rear cover assemblies 101, hinges 16, lock rod hanging ears 7, and lock tongue hanging ears 8, which are connected by pry-mounted connections. The surfaces of the bottom crossbeam 2, longitudinal beam 3, and vertical column 1 are all provided with right seven-ways 9 and left seven-ways 10. Both the left seven-way 10 and the right seven-way 9 include a transverse groove 12, and the transverse groove 12 is opened at the top of the bottom crossbeam 2. When the electrical cabinet is in rainy weather, the rainwater falling on the top of the crossbeam 2 will be collected inside the transverse groove 12. The longitudinal groove 14 is opened at the top of the longitudinal beam 3, and the rainwater falling on the top of the longitudinal beam 3 will be collected inside the longitudinal groove 14. The drainage groove 15 is opened on the surface of the vertical column 1. Drainage ports 13 are opened between the longitudinal groove 14, the transverse groove 12, and the drainage groove 15. The rainwater inside the longitudinal groove 14 and the transverse groove 12 enters the drainage groove 15 through the drainage ports 13 for drainage treatment. By draining the rainwater, it can effectively prevent rainwater or other liquids from entering the interior of the electrical cabinet, reduce the risk of short circuits and electrical failures, ensure the safe operation of the equipment, and can reduce the corrosion and damage of electrical components by moisture, thereby extending the service life of electrical equipment and reducing maintenance costs. The vertical column 1 and the bottom crossbeam 2 are formed by combining reinforcing ribs and square tubes, and the specific length depends on the size of the electrical cabinet. The longitudinal beam 3 is formed by combining reinforcing ribs and square tubes, and the specific length depends on the size of the electrical cabinet. The design of the reinforcing ribs and square tubes can significantly improve the overall strength of the electrical cabinet frame, enhance its compressive, bending, and torsional resistance capabilities, and ensure the stability of the cabinet under various environments.

[0026] Refer to Figures 1-4, based on the same concept as the above embodiments, this embodiment also proposes that the left seven-way connection 10 and the right seven-way connection 9 are pry-mounted with the vertical column 1, the bottom cross beam 2, and the longitudinal beam 3 to form the main frame. The two vertical columns of the left seven-way connection 10 and the right seven-way connection 9 in the vertical direction are inserted and pry-mounted with the vertical column 1, and the two horizontal columns are inserted and pry-mounted with the longitudinal beam 3. The pry-mounted design makes the overall structure of the electrical cabinet compact, facilitating transportation and relocation between different places, reducing the logistics cost. The modular design allows for quick assembly and disassembly, shortening the on-site installation time and improving work efficiency. The three columns in the depth direction are also inserted and pry-mounted with the longitudinal beam 3. The L-shaped fixing piece 5 is fixed on the inner frame 11 at the top and bottom positions. The inner frame 11, the rear sealing plate assembly 101, the left seven-way connection 10, and the right seven-way connection 9 need to be treated with anti-corrosion on their surfaces. The electrical cabinet treated with anti-corrosion can resist the influence of harsh environments, enhance its antioxidant and anti-corrosion capabilities, maintain long-term stability and reliability, and can adapt to various harsh environments such as high humidity, high salt, and high temperature, enhancing the extensiveness of its application. The vertical column 1, the left seven-way connection 10, the right seven-way connection 9, and the L-shaped fixing piece 5 are pry-mounted and connected. The pry-mounted design makes the maintenance and repair of the electrical cabinet more convenient. The operator can more easily check and replace components, reducing the maintenance cost.

[0027] Specifically, the working process or principle of the inner frame for an electrical cabinet is as follows: When the electrical cabinet is in a rainy weather with heavy rain, the rainwater falling on the top of the cross beam 2 will be collected inside the transverse groove 12. The longitudinal groove 14 is opened at the top of the longitudinal beam 3, and the rainwater falling on the top of the longitudinal beam 3 will be collected inside the longitudinal groove 14. The drainage groove 15 is opened on the surface of the vertical column 1. The drainage port 13 is opened between the longitudinal groove 14 and the transverse groove 12 and the drainage groove 15. The rainwater inside the longitudinal groove 14 and the transverse groove 12 enters the drainage groove 15 through the drainage port 13 for drainage treatment. By draining the rainwater, it can effectively prevent rainwater or other liquids from entering the electrical cabinet.
