Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an electrical cabinet with a bus duct bridge. Background Art

[0002] An electrical cabinet is an embedded or freestanding device used to install, protect, and connect electrical equipment. It is usually used in industrial, commercial, or other large buildings to centrally store and manage various electrical equipment, such as circuit breakers, contactors, relays, frequency converters, PLCs (programmable logic controllers), etc. The design of the electrical cabinet can be customized according to specific applications and requirements to ensure the safe operation of the equipment and facilitate maintenance.

[0003] A bus duct bridge is a metal framework used to install and support bus ducts in a power system. It provides a stable support platform for the bus ducts, ensuring that the bus ducts can be safely and orderly arranged in a distribution cabinet or an electrical system. The bus duct bridge is usually made of metal materials, has a certain strength and corrosion resistance, and can withstand the weight of the bus ducts and mechanical stresses during operation. However, the space inside the electrical cabinet is limited. Installing a bus duct bridge inside it will make the operating space inside it even smaller. After the bus duct bridge is fixed, the laying of the bus ducts is still required. At this time, the narrow space inside makes the operation difficult, and subsequent internal inspection and maintenance will also be difficult due to the limited space. Summary of the Utility Model

[0004] The purpose of the utility model is to propose an electrical cabinet with a bus duct bridge for the problems existing in the background art.

Installation columns are fixed at the four corners of the upper end of the bottom plate. The upper ends of the installation columns are fixed at the bottom of the end plates. The bottom of the side plates is hinged to the upper end of the bottom plate. A lifting sleeve is slidably connected to the outer periphery of the upper end of the end plate. The lifting sleeve is sleeved on the outer periphery of the upper end of the side plates. A lifting component is arranged inside the end plates. An installation rod is fixed between the installation columns. Electrical equipment and a bridge main body are fixed on the installation rod.

[0006] Preferably, the lifting component includes a servo motor and a driving groove. The driving groove is opened at the middle position inside the end plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions of the utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment

[0022] As Figures 1-4As shown in the figure, the electrical cabinet with a bus duct bridge proposed by the present utility model includes a bottom plate 1, an end part and side plates 3 that form the main body of the electrical cabinet. Installation columns 4 are fixed at the four corners of the upper end of the bottom plate 1. The upper ends of the installation columns 4 are fixed at the bottom of the end plate 2. The bottom of the side plate 3 is hinged to the upper end of the bottom plate 1. A lifting sleeve 7 is slidably connected to the outer periphery of the upper end of the end plate 2. The lifting sleeve 7 is sleeved on the outer periphery of the upper end of the side plate 3. A lifting assembly 8 is arranged inside the end plate 2. An installation rod 5 is fixed between the installation columns 4. Electrical equipment and a bridge main body 6 are fixed on the installation rod 5. The outer sides of the combined side plates 3 are aligned with the outer side walls of the end plate 2. A lining 71 is fixed on the inner side wall of the lifting sleeve 7, and the lining 71 is made of sealed rubber material.

[0023] The lifting assembly 8 includes a servo motor 81 and a driving groove 82. The driving groove 82 is opened at the middle position inside the end plate 2. A threaded rod 86 is rotatably connected in the driving groove 82. A driving plate 83 is slidably connected in the driving groove 82. The threaded rod 86 passes through the driving plate 83 and is threadedly connected to the driving plate 83. A connecting plate 84 is fixed on the outer periphery of the driving plate 83. The outer side of the connecting plate 84 passes through the end plate 2 and is fixed at the upper end of the lifting sleeve 7. The servo motor 81 is fixed at the center position of the upper end of the end plate 2. The output end of the servo motor 81 is fixed on the threaded rod 86. Lifting grooves 85 are opened at the side walls of the driving groove 82 and at positions corresponding to the connecting plate 84. The connecting plate 84 passes through the lifting grooves 85. Inner side baffles 9 are fixed at the bottom of the end plate 2 and at the four corners of the upper end of the bottom plate 1. The outer sides of the inner side baffles 9 are abutted against the inner sides of the side plates 3. A sealing gasket 32 is fixed on the outer periphery of the side plate 3. A positioning plate 31 is fixed above the outer side of the side plate 3. The width of the side of the positioning plate 31 is the same as the height of the bottom plate 1.

[0024] In this embodiment, first, the entire device is connected to an external power source. Then, the bridge main body 6 and the electrical equipment are fixed to the installation rod 5. During the laying of the busbars, the side plates 3 can be unfolded for operation, increasing the overall operation space and reducing the operation difficulty. When unfolding, it is necessary to drive the lifting sleeve 7 upward so that its bottom is separated from the upper end of the side plate 3, thereby enabling the side plate 3 to freely flip. Conversely, after closing, driving the lifting sleeve 7 downward can lock the combined structure at the upper end of the side plate 3. The entire process uses the drive of the servo motor 81 to drive the threaded rod 86 to rotate, enabling the driving plate 83 to move up and down in the driving groove 82. Then, through the transmission of the connecting plate 84, the lifting sleeve 7 can be quickly driven up and down. The operation is simple and convenient. Throughout the process, the inner side baffles 9 can ensure that the side plates 3 remain upright after flipping inward, and the positioning plate 31 can provide a certain limit for the downward drive of the lifting sleeve 7.

[0025] The above specific embodiments are merely several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
