Abstract
Description
Technical Field
[0001] The present application relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet. Background Art
[0002] The power distribution cabinet is the final equipment of the power distribution system and is a general term for the motor control center. It integrates electrical components for power distribution, is mainly used to distribute and control electrical equipment, and provides power-off protection when the circuit is overloaded, short-circuited, or leaking.
[0003] Most existing distribution cabinets use support plates to support and place distribution switches. Therefore, when repairing the equipment, it is often necessary to disassemble and remove the distribution switch from the surface of the support plate. The internal space of the distribution cabinet is relatively small and dark, and there are certain safety hazards when disassembling the distribution switch. Summary of the invention
[0004] The purpose of the present application is to provide a power distribution cabinet in view of at least one technical problem involved in the background technology.
[0005] In order to achieve the above objectives, this application adopts the following technical solutions:
[0006] The present application provides a power distribution cabinet, comprising a cabinet body, and a plurality of linkage rods and a plurality of rack units all located in the cabinet body, wherein the rack units are arranged in a vertical direction, the rack units are used to place a power distribution switch, and a power distribution switch access port is formed on the cabinet body.
[0007] Each of the placement rack units is slidably matched with the inner wall of the cabinet in the first direction, and each adjacent two of the placement rack units are connected by each linkage rod, so that by moving one of the placement rack units in the first direction, the other placement rack units can be driven to move in the first direction. The first direction is parallel to the horizontal plane, and each of the placement rack units is used to pass through the distribution switch access port in the first direction.
[0008] Optionally, the placement rack unit includes a single-layer push-pull plate, on which a first limiting slide groove is formed, the first limiting slide groove extends in the first direction, the single-layer push-pull plate located at the bottom of the two adjacent single-layer push-pull plates is pivotally connected to the corresponding linkage rod, and the first limiting slide groove of the single-layer push-pull plate located at the top slides with the linkage rod in the first direction.
[0009] The beneficial effect of this technical solution is that the first limiting slide groove is set to leave a certain deformation margin between the linkage rod and the single-layer push-pull plate, so that deformation within a certain range is unlikely to affect the coordination between the linkage rod and the first limiting slide groove, thereby allowing the single-layer push-pull plate to always be smoothly pulled out of the cabinet.
[0010] Optionally, the first limiting sliding grooves are formed at both ends of the single-layer pushing and pulling plates in the second direction, and any two adjacent single-layer pushing and pulling plates are connected by two connecting rods, and the two connecting rods are respectively matched with the two first limiting sliding grooves of the single-layer pushing and pulling plates located above among the two adjacent single-layer pushing and pulling plates, and the two connecting rods are respectively pivotally connected with the single-layer pushing and pulling plates located below among the two adjacent single-layer pushing and pulling plates, and the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction.
[0011] The beneficial effect of this technical solution is that any two adjacent single-layer push-pull plates are connected by two linkage rods, which can improve the stability and reliability of the linkage of the two adjacent single-layer push-pull plates.
[0012] Optionally, the linkage rod is arranged to be inclined relative to the vertical direction, and the linkage rod is perpendicular to the second direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction.
[0013] The beneficial effect of this technical solution is that it is convenient for workers to generate a component force along the length direction of the linkage rod when operating a single-layer push-pull plate, so that each single-layer push-pull plate can be quickly linked, thereby improving work efficiency.
[0014] Optionally, the single-layer sliding plate includes a plate body and a flange fixed to the plate body, the flanges are provided at both ends of the plate body in the second direction, the flanges are provided perpendicular to the plate body, the first limiting sliding groove is provided on the flange, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction.
[0015] The beneficial effect of this technical solution is that, by providing a flange specifically for setting the first limiting slide groove, compared with increasing the thickness of the plate body and setting the first limiting slide groove on the end face of the plate body, the thickness of the plate body can be reduced, the weight of the single-layer push-pull plate can be reduced, the operation of the staff is facilitated, and the manufacturing cost is saved.
[0016] Optionally, the first limiting slide groove passes through the flange in the second direction, and a clamping block is provided on the end of the linkage rod, and the clamping block and the linkage rod are located on opposite sides of the flange in the second direction, and the clamping block and the linkage rod are connected by a connecting block, and the connecting block is located in the first limiting slide groove, and the connecting block is slidably matched with the first limiting groove, and the clamping block abuts against the flange in the second direction.
[0017] The beneficial effect of this technical solution is that: in this way, the linkage rod can be connected to the flange through the connecting block and the clamping block, and slidingly cooperate with the first limiting slide groove, so that the clamping block abuts against the flange, thereby limiting the relative position of the linkage rod and the flange in the second direction, thereby making the connection between the linkage rod and the flange more firm.
[0018] Optionally, a limiting protrusion is fixed on the flange, a guide slot is formed on the inner wall of the cabinet, the guide slot extends in the first direction, and the limiting protrusion is slidably matched with the guide slot.
[0019] The beneficial effect of this technical solution is that since the first limiting groove is already provided on the flange, providing the limiting protrusion on the flange instead of providing the guide groove on the flange may cause the strength of the flange to be too low, and there is a risk of the flange breaking. However, providing the limiting protrusion on the flange and providing the guide groove on the inner wall of the cabinet can avoid the guide groove from weakening the strength of the flange.
[0020] Optionally, the placement rack unit includes a single-layer push-pull plate and a limit assembly installed on the single-layer push-pull plate, and the limit assembly is used to make pressure contact with the distribution switch in a second direction to limit the position of the distribution switch on the single-layer push-pull plate, and the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction.
[0021] The beneficial effect of this technical solution is that the position of the distribution switch on the single-layer push-pull plate is limited in the second direction by pressure cooperation between the limit component and the distribution switch, which not only makes it difficult for the distribution switch to move when the single-layer push-pull plate is pushed and pulled, but also facilitates the removal of the distribution switch from the limit component in the first direction when the distribution switch is removed, thereby increasing the disassembly efficiency of the distribution switch.
[0022] Optionally, the limit assembly includes two limit modules, and the limit modules include limit blocks and limit springs connected to each other. In the second direction, the two limit blocks are located between the two limit springs, and the two limit springs are fixedly connected to the single-layer push-pull plate. In the second direction, the two limit blocks are used for pressure contact with the distribution switch.
[0023] The beneficial effect of this technical solution is that: in this way, when disassembling the distribution switch, it is only necessary to overcome the elastic force of the two limit springs, move the two limit blocks in opposite directions, separate the two limit blocks from the distribution switch, and then the distribution switch can be removed. When the distribution switch needs to be installed, the two limit blocks are also moved in opposite directions to leave enough space between the two limit blocks, place the distribution switch in the space, and then make the two limit blocks come into pressure contact with the distribution switch under the action of the two limit springs.
[0024] Optionally, the single-layer push-pull plate includes a plate body, on which a plurality of second limiting grooves are formed, the second limiting grooves extend in the second direction, each of the limiting springs is installed one-to-one in each of the second limiting grooves, and each of the limiting blocks is slidably matched with each of the second limiting grooves in the second direction.
[0025] The beneficial effect of this technical solution is that the second limit slide groove can provide guidance for the movement of the limit block, so that the movement of the limit block is not easily deflected, and the pressure direction between the limit block and the distribution switch is not easily deflected, so that the two limit modules can fix the distribution switch more firmly.
[0026] The technical solution provided by this application can achieve at least one of the following beneficial effects:
[0027] When the power distribution cabinet provided by the present application is in use, each distribution switch is placed on each placement rack unit respectively. When the power distribution switch needs to be disassembled and assembled, one of the placement rack units is pulled out of the distribution switch access port, and each placement rack unit can be pulled out of the cabinet from the distribution switch access port together. At this time, the distribution switch is located outside the cabinet, which is convenient for the staff to disassemble and assemble the power switch. After the disassembly and assembly is completed, one of the placement rack units is pushed toward the cabinet, and each placement rack unit enters the cabinet through the distribution switch access port together. This alleviates the problem of certain safety hazards when disassembling the distribution switch due to the relatively small and dim internal space of the cabinet, and improves the safety of operation.
[0028] The additional technical features and advantages of the present application will be more clearly explained in the following description, or can be understood through the specific practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0046] like Figures 1 to 3As shown, the present application provides a power distribution cabinet, including a cabinet body, and a plurality of linkage rods 9 and a plurality of rack units 2 all located in the cabinet body, each of the rack units 2 is arranged in a vertical direction, and the rack units 2 are used to place a distribution switch 12, and a distribution switch access port is formed on the cabinet body.
[0047] Each of the placement rack units 2 is slidably matched with the inner wall of the cabinet in the first direction, and each adjacent two of the placement rack units 2 are connected by each of the linkage rods 9, so that by moving one of the placement rack units 2 in the first direction, the other placement rack units 2 can be driven to move in the first direction. The first direction is parallel to the horizontal plane, and each of the placement rack units 2 is used to pass through the distribution switch access port in the first direction.
[0048] The multiple described in the embodiment of the present application means at least two. It can be understood that each placement rack unit 2 corresponds to at least one linkage rod 9 connection.
[0049] The power distribution cabinet provided by the present application, when in use, each distribution switch 12 is placed on each placement rack unit 2 respectively. When the distribution switch 12 needs to be disassembled and assembled, one of the placement rack units 2 is pulled out of the distribution switch access port, and each placement rack unit 2 can be pulled out of the cabinet from the distribution switch access port together. At this time, the distribution switch 12 is located outside the cabinet, which is convenient for the staff to disassemble and assemble the power switch. After the disassembly and assembly is completed, one of the placement rack units 2 is pushed toward the cabinet, and each placement rack unit 2 enters the cabinet through the distribution switch access port together. This alleviates the problem of certain safety hazards when disassembling the distribution switch 12 due to the relatively small and dim internal space of the cabinet, and improves the safety of operation.
[0050] Optionally, the placement rack unit 2 includes a single-layer push-pull plate 7, on which a first limiting slide groove 11 is formed, and the first limiting slide groove 11 extends in the first direction. The single-layer push-pull plate 7 located at the bottom of the two adjacent single-layer push-pull plates 7 is pivotally connected to the corresponding linkage rod 9, and the first limiting slide groove 11 of the single-layer push-pull plate 7 located at the top is slidably matched with the linkage rod 9 in the first direction. Of course, the linkage rod 9 and the two adjacent single-layer push-pull plates 7 can also be simply pivoted, but during use, the various components in the power distribution cabinet will inevitably produce certain deformations under the conditions of temperature, gravity or external collision. If the connection between the two single-layer push-pull plates 7 and the linkage rod 9 is achieved only by a simple pivoting method, the connection is easily stuck due to the above deformation, making it difficult to pull out the single-layer push-pull plates 7. The first limiting slide 11 is set to leave a certain deformation margin between the linkage rod 9 and the single-layer push-pull plates 7, so that the deformation within a certain range is difficult to affect the coordination between the linkage rod 9 and the first limiting slide 11, so that the single-layer push-pull plates 7 can always be smoothly pulled out of the cabinet. When the first limiting slide 11 is set, when each placement rack unit 2 needs to be pulled out of the cabinet, it is preferred to pull the placement rack unit 2 located at the bottom, and when each placement rack unit 2 needs to be pushed into the cabinet, it is preferred to push the placement rack unit 2 located at the top. In the embodiment of the present application, the linkage rod 9 is optionally an elastic rod, so that when a single-layer push-pull plate 7 is pulled out of the cabinet body by an appropriate distance relative to the others, the corresponding linkage rod 9 can be forced to deform, thereby achieving the single-layer push-pull plate 7 being pulled out of the cabinet body by an individual. In the embodiment of the present application, preferably, when each shelf unit 2 is located in the cabinet body, the end position of the linkage rod 9 is located in the middle of the corresponding first limiting slide groove 11, and the middle refers to the middle of the length direction of the first limiting slide groove 11, so that the single-layer push-pull plate 7 can be pulled out of the cabinet body by an individual relative to the others, and the distance is not greater than half of the length of the corresponding first limiting slide groove 11. In this way, when it is not necessary to pull all the single-layer push-pull plates 7 out of the cabinet body, the single-layer push-pull plates 7 that need to be pulled out can be pulled out by an appropriate distance individually in a targeted manner to facilitate observation, maintenance and / or disassembly.
[0051] Optionally, the first limiting sliding grooves 11 are formed at both ends of the single-layer push-pull plates 7 in the second direction, and any two adjacent single-layer push-pull plates 7 are connected by two linkage rods 9, and the two linkage rods 9 are matched with the two first limiting sliding grooves 11 of the upper single-layer push-pull plates 7 of the two adjacent single-layer push-pull plates 7 in a one-to-one correspondence, and the two linkage rods 9 are pivotally connected with the lower single-layer push-pull plates 7 of the two adjacent single-layer push-pull plates 7 in a one-to-one correspondence, and the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction. Any two adjacent single-layer push-pull plates 7 are connected by two linkage rods 9, which can improve the stability and reliability of the linkage of the two adjacent single-layer push-pull plates 7.
[0052] Optionally, the linkage rod 9 is tilted relative to the vertical direction, and the linkage rod 9 is perpendicular to the second direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction. This makes it convenient for the staff to generate a component force along the length direction of the linkage rod 9 when operating a single-layer push-pull plate 7, so that each single-layer push-pull plate 7 can be quickly linked, thereby improving work efficiency. In the embodiment of the present application, preferably, the first limiting slide groove 11 on the single-layer push-pull plate 7 is arranged close to the access port of the distribution switch, and the position where the linkage rod 9 and the single-layer push-pull plate 7 are pivotally connected is arranged away from the access port of the distribution switch in the first direction. Of course, it is also possible to set the first limiting slide groove 11 on the single-layer push-pull plate 7 away from the access port of the distribution switch in the first direction, and the position where the linkage rod 9 and the single-layer push-pull plate 7 are pivotally connected is arranged close to the access port of the distribution switch.
[0053] Optionally, the single-layer push-pull plate 7 includes a plate body 1 and a flange 10 fixed to the plate body 1, the flanges 10 are provided at both ends of the plate body 1 in the second direction, the flanges 10 are provided perpendicular to the plate body 1, the first limiting slide groove 11 is provided on the flange 10, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction. In this way, the flange 10 specially provided for setting the first limiting slide groove 11 can reduce the thickness of the plate body 1, reduce the weight of the single-layer push-pull plate 7, facilitate the operation of the staff, and save the manufacturing cost, compared with increasing the thickness of the plate body 1 and setting the first limiting slide groove 11 on the end face of the plate body 1.
[0054] Optionally, the first limiting slide groove 11 penetrates the flange 10 in the second direction, a clamping block is provided on the end of the linkage rod 9, the clamping block and the linkage rod 9 are located on opposite sides of the flange 10 in the second direction, the clamping block and the linkage rod 9 are connected by a connecting block, the connecting block is located in the first limiting slide groove 11, and the connecting block is slidably matched with the first limiting groove, and the clamping block abuts against the flange 10 in the second direction. In this way, the linkage rod 9 can be connected to the flange 10 through the connecting block and the clamping block, and slidably matched with the first limiting slide groove 11, so that the clamping block abuts against the flange 10, and the relative position of the linkage rod 9 and the flange 10 in the second direction is limited, thereby making the connection between the linkage rod 9 and the flange 10 more secure.
[0055] Optionally, a limiting protrusion 8 is fixed on the flange 10, and a guide slot is formed on the inner wall of the cabinet, the guide slot extends in the first direction, and the limiting protrusion 8 is slidably matched with the guide slot. Because the first limiting slot 11 is already provided on the flange 10, setting the limiting protrusion 8 on the flange 10 instead of setting the guide slot on the flange 10 may make the strength of the flange 10 too low, and there is a risk of the flange 10 breaking. Setting the limiting protrusion 8 on the flange 10 and setting the guide slot on the inner wall of the cabinet can avoid the weakening of the strength of the flange 10 by the guide slot; at the same time, the flange can limit the relative position of the placement rack unit 2 and the cabinet in the second direction, thereby improving the compactness of the internal structure of the distribution cabinet and improving the stability of the placement rack unit 2 relative to the cabinet. Of course, the guide slot can also be set on the flange 10, and the limiting protrusion 8 can be set on the inner wall of the cabinet. In the embodiment of the present application, a limiting protrusion 8 can be set on one single-layer sliding plate 7, or a limiting protrusion 8 can be set on all single-layer sliding plates 7; when a first limiting slide groove 11 is set on each single-layer sliding plate 7, a single-layer sliding plate 7 can be kept in the cabinet, while all or part of the other single-layer sliding plates 7 move in the first direction relative to the single-layer sliding plate 7 located in the cabinet. For example, when a limiting protrusion 8 is set on the single-layer sliding plate 7 located on the top layer, and the limiting protrusions 8 on each single-layer sliding plate 7 and the limiting slide grooves 11 on each single-layer sliding plate 7 are respectively arranged. The corresponding ends of the linkage rod 9 matched with the first limiting slide groove 11 are all located in the middle of the first limiting slide groove 11 or near the rear end of the first limiting slide groove 11 (the rear end is arranged away from the access port of the distribution switch). Then, the single-layer push-pull plates 7 below the single-layer push-pull plates 7 located on the uppermost layer can be pulled out of the access port of the distribution switch together relative to the single-layer push-pull plates 7 located on the uppermost layer. Similarly, all the single-layer push-pull plates 7 below a certain layer of single-layer push-pull plates 7 can be pulled out of the access port of the distribution switch relative to the single-layer push-pull plates 7 of that layer.
[0056] Optionally, the placement rack unit 2 includes a single-layer push-pull plate 7 and a limit assembly installed on the single-layer push-pull plate 7, and the limit assembly is used to pressure-contact the distribution switch 12 in a second direction to limit the position of the distribution switch 12 on the single-layer push-pull plate 7, and the second direction is perpendicular to the first direction, and the second direction is perpendicular to the vertical direction. The limit assembly is pressure-matched with the distribution switch 12 to limit the position of the distribution switch 12 on the single-layer push-pull plate 7 in the second direction, which not only makes it difficult for the distribution switch 12 to move when the single-layer push-pull plate 7 is pushed and pulled, but also facilitates the distribution switch 12 to be removed from the limit assembly in the first direction when the distribution switch 12 is removed, so that the disassembly efficiency of the distribution switch 12 is high.
[0057] Optionally, the limit assembly includes two limit modules 15, and the limit modules 15 include limit blocks 17 and limit springs 16 connected to each other. In the second direction, the two limit blocks 17 are located between the two limit springs 16, and the two limit springs 16 are fixedly connected to the single-layer push-pull plate 7. In the second direction, the two limit blocks 17 are used to make pressure contact with the distribution switch 12. In this way, when disassembling the distribution switch 12, it is only necessary to overcome the elastic force of the two limit springs 16, move the two limit blocks 17 in opposite directions, separate the two limit blocks 17 from the distribution switch 12, and then remove the distribution switch 12. When the distribution switch 12 needs to be installed, the two limit blocks 17 are also moved in opposite directions to leave enough space between the two limit blocks 17, and the distribution switch 12 is placed in the space, and then the two limit blocks 17 are made to make pressure contact with the distribution switch 12 under the action of the two limit springs 16. In the embodiment of the present application, preferably, a plurality of limit assemblies are provided on the single-layer push-pull plate 7 for installing a plurality of distribution switches 12 .
[0058] Optionally, the single-layer push-pull plate 7 includes a plate body 1, on which a plurality of second limiting slots 14 are formed, the second limiting slots 14 extend in the second direction, each of the limiting springs 16 is mounted on each of the second limiting slots 14 in a one-to-one correspondence, and each of the limiting blocks 17 slides and cooperates with each of the second limiting slots 14 in a one-to-one correspondence in the second direction. The second limiting slots 14 can provide guidance for the movement of the limiting blocks 17, so that the movement of the limiting blocks 17 is not easily deflected, and thus the pressure direction between the limiting blocks 17 and the distribution switch 12 is not easily deflected, so that the two limiting modules 15 can fix the distribution switch 12 more firmly. In the embodiment of the present application, a through hole for the connection cable 13 on the distribution switch 12 to pass through can be set on the plate body 1; preferably, the cabinet includes a metal shell 3 and a door panel 5, a plurality of heat dissipation holes 4 are set on the metal shell 3, the door panel 5 is installed at the distribution switch access port, and an explosion-proof glass 6 is installed on the door panel 5 for convenient observation of the interior of the cabinet.
[0059] In one or more embodiments of the present application, the power distribution cabinet includes a metal shell 3, heat dissipation holes 4, a door panel 5 and explosion-proof glass 6. A through heat dissipation hole 4 is opened on one side of the metal shell 3. The heat dissipation holes 4 are provided in several groups and are symmetrically arranged on both sides of the metal shell 3. The front end of the metal shell 3 is rotatably connected to the door panel 5 through a rotating shaft, and the explosion-proof glass 6 is fixedly connected to the inside of the door panel 5.
[0060] In one or more embodiments of the present application, four groups of the limiting protrusions 8 are provided, which are symmetrically arranged on both sides of the single-layer push-pull plate 7 .
[0061] In one or more embodiments of the present application, the distribution cabinet provided in the embodiments of the present application includes 3 to 5 layers of shelf units, and each single-layer sliding plate 7 is provided with 2 to 5 groups of distribution switches 12. Preferably, three groups of distribution switches 12 are placed on the plate body 1 of each single-layer sliding plate 7, and the distribution switches 12 of the upper and lower adjacent single-layer sliding plates 7 are fixed by connecting cables 13. An opening is provided on the surface of the plate body 1 of the single-layer sliding plate 7 corresponding to the connecting cable 13, and six groups of second limit slide grooves 14 are provided on the top of the plate body 1 of the single-layer sliding plate 7, which are respectively arranged on both sides of the three groups of distribution switches 12, and a limiting structure 15 is fixed in each group of second limit slide grooves 14.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
