[0002] Low-voltage switchgear is a very important component in all industries and fields. It plays a very important role in power transmission, distribution and power conversion. Among them, the combined low-voltage switchgear is a type of low-voltage switchgear, which refers to a switchgear that can be freely disassembled, installed and combined between the cabinet body and the base.

[0003] When several switch cabinets are arranged in combination for use, it may be inconvenient to disassemble and assemble a certain cabinet, because the existing switch cabinets are often provided with a horizontal ground rail, and the several cabinets are arranged and combined by sliding the matching parts connected to the bottom of the cabinet along the ground rail. When an internal fault occurs in one of the switch cabinets, the cabinet on the adjacent side needs to be moved out first, resulting in the inability to quickly remove and disassemble a certain cabinet in a targeted manner, affecting the combined connection efficiency of the low-voltage switch cabinet. Therefore, a combined low-voltage switch cabinet is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a combined low-voltage switch cabinet, which has the advantages of rapid and targeted combination and disassembly of the switch cabinet, etc., and solves the problem that the existing switch cabinets are often provided with horizontal ground rails, and a plurality of cabinets are arranged and combined by sliding the matching parts connected to the bottom of the cabinet along the ground rails. When an internal fault occurs in one of the switch cabinets, the cabinet on the adjacent side needs to be moved out first, resulting in the inability to quickly move out and disassemble a certain cabinet in a targeted manner, thereby affecting the combined connection efficiency of the low-voltage switch cabinet.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined low-voltage switch cabinet, comprising a combined floor and a combined mechanism arranged on the upper surface of the combined floor;

[0006] The combination mechanism comprises a plurality of longitudinal slide rails, which are arranged equidistantly along the length direction of the combination floor, and mounting plates are slidably arranged on the outer sides of two adjacent longitudinal slide rails, and bearing blocks are arranged at the four corners of the upper surface of the mounting plate, and fixing frames are inserted on the outer sides of the four bearing blocks to connect the switch cabinet with the mounting plate, and the upper surfaces of the four fixing frames are provided with cabinet bodies;

[0007] The combination mechanism also includes a limit baffle and an anti-collision column. The limit baffle is vertically arranged on the upper surface of the combined floor to limit the front end of the longitudinal slide rail. The anti-collision column is fixed to the front side of the mounting plate. A support shaft is provided on the back side of the limit baffle, and a rotating sleeve is rotatably connected to the outer side of the support shaft. An eccentric block is provided on the outer side of the rotating sleeve.

[0008] Furthermore, a handle is provided on the back side of the mounting plate to drive the cabinet to move along the longitudinal slide rail.

[0009] Furthermore, the number of the anti-collision columns and the supporting shafts is equal to the number of the mounting plates, so as to individually control the locking of the mounting plates.

[0010] Furthermore, a fixed slot corresponding to the position of the eccentric block is provided on the outer side of the anti-collision column, and the thickness of the eccentric block is equal to the distance between the inner walls on both sides of the front and rear of the fixed slot.

[0011] Furthermore, the length of the longitudinal slide rail is greater than the length of the mounting plate, so that the cabinet can be moved out of the assembly individually.

[0012] Furthermore, the fixing frame is a rectangular parallelepiped with a hollow interior and a missing bottom, a screw hole is provided on a side of the fixing frame opposite to the bearing block, and a fixing bolt is threadedly provided on the inner wall of the screw hole for fixing the fixing frame to the bearing block.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

The operator can quickly locate and remove the cabinets that need maintenance or replacement without moving the entire combination, thus saving time and labor. The modular design allows flexible combination and splitting as needed to adapt to different installation environments and space requirements. At the same time, the design of limit baffles, anti-collision columns and eccentric blocks ensures the stability and safety of the cabinets in the combined state to prevent accidental movement or collision. In addition, since it can be freely combined, the layout of the switchgear can be arranged according to the actual space and needs. When a cabinet needs to be disassembled and assembled, there is no need to move the adjacent cabinets, which reduces the impact on the entire system and improves the independence of operation.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1 In this embodiment, a combined low-voltage switch cabinet includes a combined floor 1 and a combined mechanism 2 arranged on the upper surface of the combined floor 1.

[0022] Example 2: Please refer to Figures 2 to 4 On the basis of the first embodiment, in order to independently control the switch cabinet, the combination mechanism 2 in this embodiment includes a plurality of longitudinal slide rails 21, and the plurality of longitudinal slide rails 21 are equidistantly arranged along the length direction of the combination floor 1. A mounting plate 22 is slidably arranged on the outer side of two adjacent longitudinal slide rails 21, and a bearing block 23 is arranged at the four corners of the upper surface of the mounting plate 22. A fixing frame 24 is inserted on the outer side of the four bearing blocks 23 for connecting the switch cabinet and the mounting plate 22, and a cabinet body 25 is arranged on the upper surface of the four fixing frames 24.

[0023] The combination mechanism 2 also includes a limit baffle 26 and an anti-collision column 27. The limit baffle 26 is vertically arranged on the upper surface of the combination floor 1 to limit the front end of the longitudinal slide rail 21. The anti-collision column 27 is fixed to the front of the mounting plate 22. The operator first needs to locate the cabinet 25 to be disassembled and check the positions of the limit baffle 26 and the anti-collision column 27 to ensure that they do not hinder the disassembly process. A support shaft 28 is provided on the back of the limit baffle 26, and a rotating sleeve 29 is rotatably connected to the outer side of the support shaft 28. An eccentric block 210 is provided on the outer side of the rotating sleeve 29. When independent disassembly is required, the eccentric block 210 is adjusted by rotating the sleeve 29 to disengage it from the fixed slot and unlock the mounting plate 22. The operator uses the handle on the back of the mounting plate 22 to pull the cabinet 25 along the longitudinal slide rail 21 to separate it from the combination. After the cabinet 25 is moved out, the operator can perform necessary inspection and maintenance work on the inside of the cabinet 25.

[0024] In this embodiment, a handle is provided on the back of the mounting plate 22 to drive the cabinet body 25 to move along the longitudinal slide rail 21. The number of anti-collision columns 27 and support shafts 28 is equal to the number of mounting plates 22 to individually control the locking of the mounting plate 22. A fixed slot corresponding to the position of the eccentric block 210 is provided on the outer side of the anti-collision column 27, and the thickness of the eccentric block 210 is equal to the distance between the inner walls on the front and rear sides of the fixed slot.

[0025] In this embodiment, the length of the longitudinal slide rail 21 is greater than the length of the mounting plate 22, so that the cabinet 25 can be moved out of the combination separately. Since the length of the longitudinal slide rail 21 is greater than the length of the mounting plate 22, the cabinet 25 can be completely pulled out, which is convenient for separate disassembly or maintenance. The fixing frame 24 is a rectangular block with a hollow interior and a missing bottom. The fixing frame 24 and the supporting block 23 are both provided with screw holes on the side opposite to the fixing frame 24, and the inner wall of the screw hole is threaded with a fixing bolt 211 for fixing the fixing frame 24 to the supporting block 23.

[0026] It should be noted that after completing the maintenance, the operator will reposition the cabinet body 25 onto the longitudinal slide rail 21, ensure that the cabinet body 25 is correctly aligned and pushed back to the correct position on the composite floor 1 along the slide rail, adjust the eccentric block 210 to the correct position of the fixed slot to achieve locking, confirm the position of the anti-collision column 27 and the support shaft 28, and ensure the stability of the cabinet body 25.

[0027] The working principle of the above embodiment is:

[0028] When the switch cabinet is used for independent combination control, the operator first needs to locate the cabinet body 25 to be disassembled and assembled, check the position of the limit baffle 26 and the anti-collision column 27, and ensure that they do not hinder the disassembly and assembly process. When independent disassembly is required, the eccentric block 210 is adjusted by rotating the sleeve 29 to disengage it from the fixed slot, unlock the mounting plate 22, and the operator uses the handle on the back of the mounting plate 22 to pull the cabinet body 25 along the longitudinal slide rail 21 to separate it from the combination. Since the length of the longitudinal slide rail 21 is greater than that of the mounting plate 2 2, the cabinet 25 can be completely pulled out for separate disassembly or maintenance. After the cabinet 25 is moved out, the operator can perform necessary inspection and maintenance work on the inside of the cabinet 25. After completing the maintenance, the operator puts the cabinet 25 back on the longitudinal slide rail 21, ensures that the cabinet 25 is correctly aligned and pushed back to the correct position on the composite floor 1 along the slide rail, adjusts the eccentric block 210 to the correct position of the fixed slot to achieve locking, confirms the position of the anti-collision column 27 and the support shaft 28, and ensures the stability of the cabinet 25.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] If this patent discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection can also be replaced by an integrated structure (for example, manufactured by a casting process) (except where it is obviously impossible to use an integrated forming process).

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
