Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, specifically relating to a reinforced support structure for an electrical cabinet. Background Technology

[0002] Electrical cabinets, such as high-voltage switchgear, which are used to carry electrical components, are widely used in power distribution systems. The cabinets need to be equipped with partitioned load-bearing components to separate independent electrical chambers and carry electrical components such as circuit breakers and transformers, so as to realize the zoning of equipment and safe operation and maintenance.

[0003] However, most existing high-voltage switchgear relies solely on a single flat plate as a load-bearing partition. This plate itself is structurally weak and prone to bending and sagging under the loads of heavy electrical components and long-term equipment vibration, resulting in poor structural stability. Therefore, a reinforced support structure for electrical switchgear is urgently needed. Utility Model Content

[0004] This utility model improves the overall strength of the load-bearing structure by setting interlocking first and second load-bearing columns on the base plate to form a grid load-bearing structure, and by arranging corner reinforcements with locking pressure plates at the intersection of the columns, and by using oblique locking components to fasten the columns and corner reinforcements, thereby solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: a reinforced support structure for an electrical cabinet includes a cabinet body and at least one support base plate arranged at intervals along the height of the cabinet body, and further includes: Multiple first-bearing columns are integrally installed on the top surface of the supporting base plate; Multiple second load-bearing columns are interlocked with each of the first load-bearing columns through corresponding notches to form a grid load-bearing structure; An angular reinforcing member is provided at the intersection of the first and second supporting columns, and the angular reinforcing member is provided with a locking pressure plate; An oblique locking assembly securely connects the angular reinforcing member, the first bearing column, and the second bearing column, and the pressure-bearing surface of the locking pressure platform is perpendicular to the through axis of the oblique locking assembly.

[0006] The present invention is further configured such that the supporting base plate is detachably connected to the cabinet body.

[0007] The present invention is further configured such that the top surfaces of the first and second supporting columns are flush after they are plugged together and assembled; and the top surface of the corner-shaped reinforcing member is flush with the top surfaces of the first and second supporting columns after assembly.

[0008] The present invention is further configured such that the angular reinforcing member is an integral bent structure, comprising a first plate and a second plate connected to each other, wherein the first plate is attached to the side wall of the first bearing column and the second plate is attached to the side wall of the second bearing column.

[0009] The present invention is further configured such that the lower sides of the first plate and the second plate are provided with positioning notches, and the tops of the first and second supporting columns are respectively provided with matching mating notches, and the angular reinforcing members are pre-positioned by engaging with the corresponding mating notches through the positioning notches.

[0010] The present invention is further configured such that the corresponding notch specifically includes a lower insertion notch located on the upper part of the first supporting column and an upper insertion notch located on the lower part of the second supporting column, and the two sets of notches fit together to realize the insertion and connection of the columns.

[0011] The present invention is further configured such that the two ends of the angular reinforcing member are respectively integrally formed into the locking pressure platform, and the oblique locking assembly includes a locking bolt and a locking nut. The locking bolt passes through the first plate, the first bearing column, the second bearing column and the second plate in sequence, and is then threadedly locked with the locking nut.

[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. By connecting the first and second load-bearing columns on the base plate to form a grid support system, the load-bearing pressure of the components is distributed, thereby improving the load-bearing capacity of the internal load-bearing structure of the cabinet.

[0013] 2. By using angular reinforcing members at the staggered positions of the columns in combination with oblique locking components to lock the columns in both directions, the relative displacement of the columns is constrained, thereby improving the vibration and deformation resistance of the load-bearing structure.

[0014] 3. By evenly distributing the bolt tightening force through a locking pressure plate that is perpendicular to the inclined locking axis, the plate is prevented from being damaged by local pressure, thus improving the stability and reliability of the locking connection.

See also: Figure 1-5 : Example: This embodiment provides a reinforced support structure for an electrical cabinet, including a cabinet body 1 and at least one support base plate 2 arranged at intervals along the height of the cabinet body 1, and further including: Multiple first load-bearing columns 3 are integrally installed on the top surface of the supporting base plate 2; Multiple second load-bearing columns 4 are interlocked with each of the first load-bearing columns 3 through corresponding notches to form a grid load-bearing structure 5; An angular reinforcing member 6 is provided at the intersection of the first supporting column 3 and the second supporting column 4, and the angular reinforcing member 6 is provided with a locking pressure plate 61; The oblique locking assembly 7 fastens the angular reinforcing member 6, the first bearing column 3, and the second bearing column 4 together, and the bearing surface of the locking pressure platform 61 is perpendicular to the through axis of the oblique locking assembly 7.

[0018] This specific embodiment relates to a reinforced support structure for an electrical cabinet, applied inside electrical distribution equipment such as high-voltage switchgear, used to partition the internal space of the cabinet 1 and support electrical components such as circuit breakers and transformers. The structure is composed of the cabinet 1, a support base plate 2, a first support column 3, a second support column 4, corner reinforcements 6, and an oblique locking assembly 7. Stable partitioning and load-bearing functions are achieved through a grid support structure 5 combined with locking reinforcement structures at intersections.

[0019] Cabinet 1 is the external supporting shell of the electrical cabinet, used to enclose and form the internal installation space. The function of the supporting base plate 2 is to separate the internal chambers of cabinet 1 and serve as the installation base for the load-bearing structure. Its structure is a rectangular metal plate, the shape of which is adapted to the cross-section of the internal cavity of cabinet 1. Its position is arranged along the height direction of cabinet 1. At least one supporting base plate 2 can be installed inside cabinet 1. When multiple supporting base plates 2 are arranged at intervals along the height of cabinet 1, cabinet 1 can be divided into multiple independent chambers. The supporting base plate 2 and cabinet 1 are connected in a detachable manner. Specifically, multiple sets of L-shaped support brackets are welded and fixed at corresponding height positions on the left and right sides of the inner wall of cabinet 1 and the front and rear crossbeams. The four sides of the supporting base plate 2 extend outward mounting edges, and the outward mounting edges are provided with through holes. The mounting edges are placed on the horizontal bearing surface of the L-shaped support brackets. The fastening bolts pass vertically through the through holes of the mounting edges and lock with the threaded holes of the brackets, so as to realize the detachable locking of the supporting base plate 2.

[0020] The function of the first load-bearing column 3 is to form the longitudinal support skeleton of the grid load-bearing structure 5, and to transfer and distribute the load of the upper components. Its structure is a long strip of metal profile with a rectangular cross section. The upper part has downward recessed insertion notches 8 spaced apart along the length direction. The notches are located on the top surface of the base plate 2 and are arranged in parallel along the left and right directions. The bottom of the first load-bearing column 3 and the top surface of the base plate 2 are integrally formed. The two can be made by integral stamping and bending process or by welding to achieve a fixed connection, so as to ensure the connection strength between the column and the base plate.

[0021] The function of the second supporting column 4 is to form a complete grid supporting structure 5 by interleaving with the first supporting column 3. Its structure is a long strip of metal profile with the same thickness and height as the first supporting column 3. The cross-section is rectangular, and the lower part has upwardly recessed upper insertion notches 9 spaced apart along the length direction. The notches are arranged parallel to each other in the front-back direction and are perpendicular to the first supporting column 3. The second supporting column 4 is inserted and matched with the lower insertion notch 8 of the first supporting column 3 through its own upper insertion notch 9. In the fitted state, the bottoms of the two sets of notches abut against each other and limit each other. After the insertion and assembly is completed, the top surfaces of the first supporting column 3 and the second supporting column 4 are on the same horizontal plane, forming a flat grid supporting surface.

[0022] The function of the angular reinforcing member 6 is to reinforce the intersecting position of the first bearing column 3 and the second bearing column 4, constrain the relative displacement of the two columns, and prevent the insertion notch from deforming under load. It is an integrally bent metal component with an overall right-angled angular structure, including a first plate 62 and a second plate 63 that are perpendicularly connected to each other; both the first plate 62 and the second plate 63 have upwardly recessed positioning notches 64 on their lower sides, and the two outer ends of the component are integrally formed with locking pressure plates 61, the outer end face of which is an inclined plane; the angular reinforcing member 6 is provided with At the outer corner where the two columns intersect, the inner wall of the first plate 62 is completely fitted with the outer wall of the first supporting column 3, and the inner wall of the second plate 63 is completely fitted with the outer wall of the second supporting column 4. Correspondingly, the top of the first supporting column 3 and the second supporting column 4 are respectively provided with mating notches 10 that are adapted to the positioning notch 64. The corner reinforcement 6 is pre-installed and positioned by snapping into the corresponding mating notch 10 through the positioning notch 64. After the snapping is completed, the top surface of the corner reinforcement 6 is flush with the top surfaces of the first supporting column 3 and the second supporting column 4.

[0023] The function of the oblique locking assembly 7 is to tighten the angled reinforcing member 6 and the two supporting columns in a diagonal direction, thereby achieving a tight connection between the three. It is composed of a locking bolt 71 and a locking nut 72. The oblique locking assembly 7 is inclined and inserted in a diagonal direction along the angled reinforcing member 6. Its insertion axis is perpendicular to the outer end face of the locking pressure platform 61. The locking bolt 71 is inserted from one side of the locking pressure platform 61 at the end of the first plate 62, and passes through the plate body of the first plate 62, the column body of the first supporting column 3, the column body of the second supporting column 4, and the plate body of the second plate 63 in sequence. It then exits from one side of the locking pressure platform 61 at the end of the second plate 63, and the exit end is screwed into the locking nut 72. In the locked state, the head end face of the locking bolt 71 is tightly abutted against the outer end face of one side of the locking pressure platform 61, and the end face of the locking nut 72 is tightly abutted against the outer end face of the other side of the locking pressure platform 61, ensuring that the locking force is evenly transmitted along the bolt axis. The first plate 62, the second plate 63, the first bearing column 3, and the second bearing column 4 are all provided with coaxial inclined through holes at staggered positions. The axis of all through holes is perpendicular to the bearing surface of the locking bearing platform 61, and the locking bolts 71 are completely inserted along the coaxial through holes.

[0024] The assembly process of the reinforced support structure is as follows: First, multiple parallel first support columns 3 are machined and formed on the top surface of the support base plate 2. Then, the second support columns 4 are inserted downwards at the staggered positions corresponding to the first support columns 3, so that the upper and lower sets of insertion notches fit together to form a flat grid support structure 5. Afterwards, corner reinforcements 6 are installed at the outer corners of each column intersection position. The positioning notch 64 of the reinforcement is aligned with the mating notch 10 at the top of the column and inserted downwards, so that the two plates are respectively attached to the corresponding... Pre-installation and positioning are completed on the side wall of the column; finally, the locking bolts 71 are inserted into the corner reinforcement 6 and the two columns in a diagonal direction, and after they are pulled out, the locking nuts 72 are tightened to complete the locking and reinforcement at the single staggered position; after all grid positions are assembled, the entire supporting base plate 2 is hoisted into the cabinet 1, placed on the support bracket at the corresponding height and the bolts 71 are tightened to complete the installation inside the cabinet 1; according to the requirements of the chamber partition, the above steps can be repeated inside the cabinet 1 to install the multi-layer supporting base plate 2 structure.

[0025] In the above structure, the base plate 2 can achieve physical separation inside the cabinet 1, meeting the isolation requirements of different chambers; the crisscrossing plug-in grid columns can distribute the load of components and improve the overall load-bearing capacity; the corner reinforcement 6, together with the oblique locking assembly 7, can bidirectionally constrain the staggered position of the columns and counteract the stress deformation trend at the plug-in notch; the locking pressure plate 61, which is perpendicular to the locking axis, can ensure that the bearing surfaces of the bolt and nut are completely in contact when locking obliquely, avoiding connection failure caused by locking off-center load and improving the operational stability of the overall structure.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
