Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to an electrical component installation structure for a power distribution cabinet. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Several electrical components need to be installed in the shell of the distribution cabinet. In order to facilitate wiring and play a protective role, adjustment rods are generally installed vertically on both sides of the distribution cabinet shell. Each adjustment rod is provided with several adjustment grooves arranged along the length direction of the adjustment rod, and a support beam group is installed between the two adjustment rods. Each support beam group includes two support beams parallel to each other. Both ends of each support beam are fixed to the corresponding adjustment rods respectively by bolt locking. The bolts for locking the support beams pass through the adjustment grooves, so that each support beam can adjust its position according to actual needs. The electrical components are detachably installed on the support beam group by bolt locking.

[0004] Among them, when the electrical components are installed on the support beam group, the upper and lower ends of the electrical components are respectively fitted with two support beams, and the four end corners of the electrical components are fixedly connected to the corresponding support beams by bolt locking; the spacing between the two support beams constituting the support beam group is adjusted according to the actual specifications of the electrical components.

[0005] With respect to the above-mentioned related technologies, the applicant has found that electrical components have different specifications according to actual needs. When arranging electrical components in a distribution cabinet, in principle, multiple electrical components of the same specification are installed on the same support beam group. However, in actual use, it is found that some specifications of electrical components are used in small quantities and cannot completely fill a group of support beam groups, while some specifications of electrical components are used in large quantities and cannot be completely installed in a group of support beam groups. Using two groups of support beam groups will leave a lot of remaining space, resulting in low space utilization inside the distribution cabinet, which needs to be improved. Summary of the invention

[0006] The purpose of the present application is to provide an electrical component installation structure for a power distribution cabinet, which has the function of enabling a support beam group to be filled with electrical components as much as possible, thereby improving the space utilization inside the power distribution cabinet.

[0007] The present application provides an electrical component installation structure for a power distribution cabinet using the following technical solution:

[0008] A structure for mounting electrical components in a power distribution cabinet comprises a shell, an adjustment rod, a support beam group and an elastic adjustment component, wherein one adjustment rod is respectively provided on two opposite surfaces inside the shell, the support beam group comprises two support beams which are respectively parallel to each other, and the two ends of the two support beams are respectively fixedly connected to the two adjustment rods, and the spacing between the two support beams is adjustable, and the elastic adjustment component comprises an elastic connector, one side of which is connected to any support beam, and the spacing between the other side of the elastic connector and the support beam is adjustable, and the side of the elastic connector away from the support beam can be fixedly connected to one end of the electrical component by bolt locking.

[0009] By adopting the above technical solution, the shell is used for the main supporting and bearing function, the adjusting rod is used to support and connect the support beams, and the distance between the two support beams can be adjusted according to actual needs, so that the two support beams can be fixedly connected with the upper and lower ends of a certain specified specification of electrical components respectively; then an elastic connector is installed on any one of the support beams, and the distance between the elastic connector and any one of the support beams is adjusted, so that the elastic connector is located on one side of the support beam connection and one of the support beams can be fixedly connected with the upper and lower ends of another specified specification of electrical components respectively. In this way, at least two different specifications of electrical components can be installed on a group of support beams, making the space on the support beam group more flexible, so that the support beam group can be filled with electrical components as much as possible, and the space utilization rate inside the distribution cabinet is limitedly improved.

[0010] Optionally, the elastic connector includes a connecting plate and two elastic sheets, one end of the two elastic sheets is fixedly connected to the connecting plate by means of bolt locking, and the other ends of the two elastic sheets are fixedly connected to the same support beam. When the elastic connector is connected to electrical components, the bolts used to lock the electrical components pass through the connecting plate.

[0011] By adopting the above technical solution, the connecting plate is used to be fixedly connected to one end of the electrical component away from the support beam, and both ends of the connecting plate can be connected to the support beam through elastic sheets. When the height position of the connecting plate needs to be adjusted, it is only necessary to adjust the positions of the two elastic sheets. In addition, due to problems with processing accuracy and installation accuracy, it is difficult to ensure that the two ends of the electrical component can be tightly connected to the connecting plate and the support beam respectively. Therefore, the elastic ability of the elastic sheet is utilized to enable the connecting plate to adjust its position in the horizontal direction to ensure that the connecting plate can be firmly connected to the ends of the electrical components.

[0012] Optionally, the elastic sheet includes a first connecting portion, a bending portion and a second connecting portion formed by continuous bending of metal, the first connecting portion is fixedly connected to the support beam by bolt locking, and the second connecting portion is fixedly connected to the connecting plate by bolt locking.

[0013] By adopting the above technical solution, the bending portion can be used to stagger the planes where the first connecting portion and the second connecting portion are located, so that the elastic sheet can have a larger elastic deformation space. The bolt locking method can not only fix the elastic sheet and the connecting plate and the support beam, but also facilitate the adjustment of the angle between the elastic sheet and the connecting plate and the support beam.

[0014] Optionally, both ends of the connecting plate are rotatably connected with adjusting screws, and the other end of each adjusting screw is threadedly connected to the same supporting beam.

[0015] By adopting the above technical solution, both ends of the elastic plate are fixedly connected to the connecting plate and the support beam respectively by means of bolt locking, which will make it difficult to rotate the elastic plate and it is difficult to accurately adjust the position of the connecting plate. Therefore, using an adjustment screw that can be raised and lowered relative to the support beam to push the connecting plate up and down can more conveniently and accurately push the connecting plate to adjust the height position.

[0016] Optionally, when the elastic connector is connected to the support beam, the bent portion is located directly above or below the support beam, and a side surface where the connecting plate and the electrical component are in contact with each other coincides with a side surface where the support beam and the electrical component are in contact with each other.

[0017] By adopting the above technical solution, by making the bending portion located directly above or below the support beam, the side surface where the connecting plate and the electrical component are in contact with the side surface where the support beam and the electrical component are in contact with each other overlaps, thereby facilitating fixed connection of the two ends of the electrical component with the elastic connector and the support beam respectively.

[0018] Optionally, both support beams are provided with a convex edge, each of the convex edges is located on a side surface where the support beam is connected to the electrical component, and each of the convex edges extends along the length direction of the support beam. When the two ends of the electrical component are respectively against the two support beams, the lower end surface of the electrical component can be against the top of the convex edge, and the hole at the upper end of the electrical component for the bolt to lock is located between the two support beams.

[0019] By adopting the above technical solution, the two ends of the electrical component can be respectively abutted against the two support beams, and then when the lower part of the upper end of the electrical component is fixedly connected to the connecting plate, the convex edge can be used to support the lower end of the electrical component, so that although only the upper end of the electrical component is fixed by the connecting plate, the support stability can be guaranteed.

[0020] Optionally, the elastic adjustment component includes two elastic connectors, one side of the two elastic connectors is respectively fixedly connected to two support beams, and the other sides of the two elastic connectors can be respectively fixedly connected to designated ends of electrical components.

[0021] By adopting the above technical solution and this method, an electrical component can be directly connected between two support beams, an electrical component can be directly connected between two elastic connectors, and the two elastic connectors can respectively cooperate with the two support beams to connect at least two electrical components of specified specifications, thereby meeting more installation requirements.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. At least two different specifications of electrical components can be installed on a set of support beams, so that the support beams can have more safe options, so that the support beams can be filled with electrical components as much as possible;

[0024] 2. The height adjustment of the connecting plate is convenient, accurate and flexible, which can meet more installation requirements with less cost increase;

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0035] Embodiment 1:

[0036] An electrical component installation structure for a power distribution cabinet, referring to Figure 1 and Figure 2 , including a shell 1, an adjusting rod 2, a support beam group 3 and an elastic adjustment component 4, the shell 1 plays a major supporting and bearing role, two adjusting rods 2 are vertically arranged, and the two adjusting rods 2 are respectively installed on the two vertical sides of the shell 1, the support beam group 3 includes two support beams 31 parallel to each other, and the two ends of the support beam 31 are respectively fixedly connected to the two adjusting rods 2, and the elastic adjustment component 4 includes an elastic connector 41, one side of the elastic connector 41 is detachably connected to any one of the support beams 31.

[0037] Among them, the distance between the two support beams 31 can be adjusted according to actual needs, so that the two support beams 31 can be fixedly connected to the upper and lower ends of an electrical component of a specified specification respectively; the elastic connecting member 41 is located on one side of the support beam 31 and can be fixedly connected to one end of another electrical component of a specified specification, and the other end of the electrical component can be fixedly connected to any support beam 31 according to actual needs.

[0038] Reference Figure 3 Each supporting beam 31 includes a mounting portion 311, a reinforcement portion 312 and a connection portion 313. The mounting portion 311, the reinforcement portion 312 and the connection portion 313 are all arranged in a thin plate shape. Two reinforcement portions 312 are arranged in parallel with each other. The two reinforcement portions 312 are formed by bending the two long sides of the mounting portion 311 at 90 degrees. Two connection portions 313 are arranged on the same plane. The two connection portions 313 are formed by bending the two long sides of the two reinforcement portions 312 away from the mounting portion 311 at 90 degrees, and the two connection portions 313 are arranged facing each other on the long sides away from the reinforcement portion 312; wherein, a plurality of first waist-shaped grooves 314 are arranged on the mounting portion 311 at equal intervals along the length direction of the mounting portion 311.

[0039] When the support beam 31 is installed in the shell 1, both ends of the two connecting parts 313 are respectively fitted with the two adjusting rods 2, and the bolts used to lock the support beam 31 and the adjusting rods 2 pass through the first waist-shaped groove 314 at the end of the installation part 311.

[0040] Reference Figure 2 and Figure 4 Each elastic connector 41 includes an elastic sheet 411 and a connecting plate 412. Two elastic sheets 411 are provided. One end of the two elastic sheets 411 is fixedly connected to the same support beam 31, and the other ends of the two elastic sheets 411 are fixedly connected to the connecting plate 412. The elastic sheet 411 includes a first connecting portion 413, a bending portion 414, and a second connecting portion 415 arranged in sequence. The first connecting portion 413 and the second connecting portion 415 are parallel to each other, and the first connecting portion 413 and the second connecting portion 415 are located on the same plane. The elastic sheet 411 is formed by punching and bending a metal material. When the elastic connector 41 is used, the first connecting portion 413 is connected to the support beam 31, the second connecting portion 415 is connected to the connecting plate 412, and the connecting plate 412 is connected to the end of the electrical component.

[0041] Among them, a plurality of second waist-shaped grooves 416 are provided on the connecting plate 412, and each second waist-shaped groove 416 is arranged along the length direction of the connecting plate 412. The elastic sheet 411 and the support beam 31 are detachably connected by bolt locking, and the elastic sheet 411 and the connecting plate 412 are detachably connected by bolt locking. When the electrical components are connected to the connecting plate 412 or the support beam 31 by bolt locking, the bolts used to lock the electrical components pass through the first waist-shaped groove 314 or the second waist-shaped groove 416.

[0042] Reference Figure 4 When the first connecting portion 413 is connected to one side surface of the support beam 31 and the bending portion 414 is located between or outside the support beams 31, the side surface of the connecting plate 412 away from the first connecting portion 413 is on the same vertical plane as the other side surface of the support beam 31; when the bending portion 414 is located between two support beams 31, the connecting plate 412 can divide the space between the two support beams 31, and when the bending portion 414 is located outside the two support beams 31, the connecting plate 412 can expand new installation controls outside the two support beams 31, so that when a group of support beam groups 3 is matched with a group of elastic adjustment components 4, 2 or 3 electrical components of different specifications can be installed, and when a group of support beam groups 3 is matched with more groups of elastic adjustment components 4, more electrical components of different specifications can be installed.

[0043] The implementation principle of the embodiment of the present application is:

[0044] This embodiment specifically uses a group of support beams 3 and a group of elastic adjustment components 4 to make the following example. The following example is a state in which the connecting plate 412 is located between two support beams 31.

[0045] When installing two electrical components of different specifications, first adjust the distance between the two support beams 31 so that the two ends of the larger electrical component can be fixed to the two support beams 31 respectively; then fix the two ends of the smaller electrical component to the connecting plate 412 and the corresponding support beam 31 respectively. The distance between the connecting plate 412 and the support beam 31 can be adjusted by adjusting the connection between the elastic sheet 411 and the support beam 31.

[0046] When installing three electrical components of different specifications, when this method is used, the three electrical components of different specifications need to include one large-sized electrical component and two small-sized electrical components; specifically, first adjust the spacing between the two support beams 31 so that the two ends of the larger electrical component can be fixed to the two support beams 31 respectively, and then fix the two ends of one of the small-sized electrical components to the connecting plate 412 and one of the support beams 31 respectively, and fix the two ends of the other small-sized electrical component to the connecting plate 412 and the other support beam 31 respectively. It should be noted that when this method is used, the size ratio of the two small-sized electrical components is limited, and it should be satisfied that one end of the two small-sized electrical components can be fixedly connected to the connecting plate 412, and the other ends of the two small-sized electrical components can be fixedly connected to the two support beams 31 respectively.

[0047] Embodiment 2:

[0048] Reference Figure 5 The difference between the embodiment of the present application and embodiment 1 is that a protrusion 315 is provided on each of the two support beams 31, each protrusion 315 is located on the side surface where the support beam 31 is connected to the electrical components, and each protrusion 315 extends along the length direction of the support beam 31; wherein each protrusion 315 is located on the side of the support beam 31 away from the center of the support beam group 3.

[0049] When the elastic connector 41 is connected to the support beam 31, the side of the connecting plate 412 close to the electrical component is offset from the side where the support beam 31 and the electrical component are in contact, and the connecting plate 412 is located between the two support beams 31. When the two ends of the electrical component are respectively against the two support beams 31, the hole at the upper end of the electrical component for the bolt to lock and pass through is located between the two support beams 31.

[0050] The implementation principle of the embodiment of the present application is:

[0051] First, the distance between the two support beams 31 is adjusted so that two ends of one specification of the electrical components can be fixedly connected to the two support beams 31 respectively.

[0052] Then, the upper and lower ends of an electrical component of another specification are respectively placed against the surfaces of the mounting portions 311 of the two support beams 31 , and the lower end of the electrical component is placed above the convex edge 315 , and then the upper end of the electrical component is locked together with the connecting plate 412 .

[0053] When locking the electrical components and the connecting plate 412, the electrical components and the connecting plate 412 are not directly connected, but indirectly connected through locking bolts. At this time, in order to ensure that the electrical components and the connecting plate 412 are tightly connected, the electrical components and the connecting plate 412 should be locked and clamped with bolts and nuts so that the second connecting portion 415 can be bent in the direction close to the electrical components (that is, the planes where the first connecting portion 413 and the second connecting portion 415 are located intersect).

[0054] In the above process, the bending portion 414 is bent under force, so a certain elastic restoring force is generated, which can exert a force on the electrical component in the direction close to the second connecting portion 415, so that the upper and lower ends of the electrical component can be firmly against the two support beams 31. At the same time, the electrical component can be supported by the convex edge 315 to prevent the electrical component from shaking randomly.

[0055] Embodiment 3:

[0056] Reference Figure 6 The difference between the embodiment of the present application and embodiment 1 is that the elastic adjustment component 4 includes two elastic connectors 41, one side of the two elastic connectors 41 is detachably connected to the two support beams 31 respectively, and the other side of the two elastic connectors 41 is fixedly connected to the end of the corresponding electrical components.

[0057] Reference Figure 3 Similar to Example 1, when the elastic connector 41 is connected to the support beam 31, the bent portion 414 of the elastic connector 41 is located between or outside the support beams 31, and the side of the connecting plate 412 of the elastic connector 41 away from the first connecting portion 413 is on the same vertical plane as the other side of the support beam 31, so that when one end of the electrical component is fixedly connected to the support beam 31, the other end of the electrical component can be fixedly connected to the connecting plate 412 at the corresponding position.

[0058] The implementation principle of the embodiment of the present application is:

[0059] First, the distance between the two support beams 31 is adjusted so that the two ends of one specification of the electrical component can be fixedly connected to the two support beams 31 respectively, and the two ends of the other specification of the electrical component can be fixedly connected to the two connecting plates 412 respectively.

[0060] Then, the distance between any one of the connection plates 412 and any one of the support rods can be adjusted so that the connection plates 412 and the support rods can be fixedly connected to the two ends of another electrical component of a specified specification, respectively.

[0061] Embodiment 4:

[0062] Reference Figure 7 , the difference from Example 1 is that an adjustment plate 417 is provided on one of the long sides of the connecting plate 412, the adjustment plate 417 is provided with two pieces and is respectively located at the two ends of the connecting plate 412, the plane where the adjustment plate 417 is located is perpendicular to the plane where the connecting plate 412 is located, and a plurality of threaded holes are provided on the support beam 31, and each threaded hole is arranged equidistantly along the length direction of the support beam 31; wherein, an adjusting screw 5 is installed on the support beam 31, one end of the adjusting screw 5 is threadedly connected to the support beam 31 through the threaded hole, and the other end of the adjusting screw 5 is rotatably connected to the adjusting plate 417.

[0063] Among them, a number of through holes 316 are arranged on the two reinforcement parts of the support beam 31, and the adjusting screw 5 can pass through the support beam 31 through the through holes 316. Nuts are also welded and fixed on the side surfaces of the two support beams 31 that are arranged oppositely, and the threaded holes arranged on the support beam 31 are the threaded holes in the nuts.

[0064] The implementation principle of the embodiment of the present application is:

[0065] The two ends of the elastic sheet 411 are fixedly connected to the support beam 31 and the connecting plate 412 by bolt locking. To ensure a stable connection, the bolts and nuts used to lock the elastic sheet 411 are tightly matched, making it difficult to adjust the position of the connecting plate 412 once it is fixed.

[0066] When the position of the connecting plate 412 needs to be adjusted, the adjusting screw 5 can be rotated. By utilizing the threaded connection between the adjusting screw 5 and the support beam 31, and the rotational connection between the adjusting screw 5 and the connecting plate 412, the staff can forcibly adjust the height of the connecting plate 412 by rotating the adjusting screw 5, which makes the adjustment convenient and safe.

[0067] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
