Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a modular and easily disassembled combined power distribution cabinet. Background Art

[0002] With the rapid development of power systems and the acceleration of urbanization, distribution networks are becoming increasingly complex, placing increasing demands on distribution equipment. While traditional distribution cabinets play a vital role in power systems, they suffer from numerous limitations, such as bulk, rigid structure, limited scalability, and difficult installation and maintenance. These issues limit their flexibility and efficiency in modern power systems. This is particularly true in scenarios requiring frequent configuration changes or rapid deployment, where traditional distribution cabinets are insufficient.

[0003] Some distribution cabinets in the existing technology have modular designs, but there are problems such as weak connections between modules, cumbersome assembly process, and insufficient stability, which makes it difficult to meet the actual application requirements of high efficiency, safety, and convenience. At the same time, the mother modules of existing basic distribution cabinets are all fixed assembly methods. When replacing the mother module, it is necessary to remove screws in the front and back directions. There are many panels to disassemble, and the process is relatively cumbersome. Therefore, providing a modular combination distribution cabinet that can ensure structural stability, achieve rapid disassembly and assembly, and meet different functional requirements has become the focus of current technology research and development. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a modular and easily disassembled combined power distribution cabinet, which solves the problems of cumbersome assembly of existing modular power distribution cabinets and difficulty in replacing the mother modules in the basic power distribution cabinet.

[0005] To achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a modular and easily disassembled combined power distribution cabinet, comprising a basic cabinet and a plurality of assembly cabinets assembled on the basic cabinet, side panels being fixed on both sides of the basic cabinet, and a mother module and a child module being respectively arranged in the basic cabinet and the assembly cabinet;

[0006] The basic cabinet and the assembly cabinet are respectively provided with a first main vertical beam and a second main vertical beam, wherein when the assembly cabinets are assembled with each other or with the basic cabinet, two adjacent second main vertical beams are assembled and connected or the second main vertical beam is assembled and connected with the first main vertical beam;

[0007] A plurality of main beams are provided in the basic cabinet, and rollers are provided on the side walls of the mother module. The rollers are connected to the main beams in a rolling manner; and fixing parts for the rollers are provided on the main beams.

[0008] Preferably, a notch groove is provided on the front side of the main crossbeam, and a clamping groove is extended from the notch groove toward the cabinet door of the basic cabinet body. After the roller enters the clamping groove, it is locked by the fixing member.

[0010] Preferably, a lap beam is provided on the inner side of the main beam, and the female module is seated on the lap beam when the roller is locked by the fixing member.

[0011] Preferably, the notch groove extends from one side of the clamping groove toward the top surface of the main beam to form a continuously curved surface.

[0012] Preferably, an outer back plate capable of fixing the side panels is provided on the outer side of the main cross beam; the side panels include:

[0013] Basic cabinet side panels, fixed to the basic cabinet;

[0014] The side panel has one end hinged on the first main vertical beam and the other end connected to the side panel of the basic cabinet through a letter lock; the side panel covers one side of the notch groove.

[0015] Preferably, two adjacent second main vertical beams or the second main vertical beam and the first main vertical beam are connected by a connecting plug-in assembly; the connecting plug-in includes:

[0016] An insert tube, which is inserted into the cavities of two adjacent second main vertical beams or the second main vertical beam and the first main vertical beam; the insert tube is provided with a bolt hole through which a screw can pass;

[0017] The middle plate is fixed on the outer wall surface of the insert tube. When the insert tube is inserted into the cavity, the second main vertical beam and the first main vertical beam abut against the middle plate.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0029] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0030] Reference Figure 1-6 The modular and easily disassembled combined power distribution cabinet of this implementation scheme is described.

[0031] like Figure 1 As shown, the power distribution cabinet comprises a base cabinet 1 and multiple assembly cabinets 2 mounted on top of the base cabinet 1. The assembly cabinets 2 can be stacked and assembled on top of the base cabinet 1. Side panels are fixed to both sides of the base cabinet 1, and doors are provided on the fronts of both the base cabinet 1 and the assembly cabinet 2. The top cover of the base cabinet 1 can be assembled onto the topmost assembly cabinet 2 to form a complete power distribution cabinet. The base cabinet 1 and assembly cabinet 2 each contain a mother module 3 and a submodule 4. The submodule 4 includes indicator lights and a meter module, an ATSE input module, and air conditioners or other mains loads. The mother module 3 includes UPS main and bypass inputs, UPS output and maintenance bypass, and UPS loads. Depending on actual usage requirements, the submodule 4 is assembled into the assembly cabinet 2. After removing the top cover of the base cabinet 1, the assembly cabinet 2 is secured to the top of the base cabinet 1. Wiring is then connected, and the cover is secured to the top of the assembly cabinet 2.

[0032] The first main vertical beam 7 and the second main vertical beam 8 are respectively provided in the basic cabinet 1 and the assembly cabinet 2. Figure 5 and Figure 6 As shown, when the assembled cabinets 2 are assembled with each other or with the basic cabinet 1 , two adjacent second main vertical beams 8 are assembled and connected or the second main vertical beam 8 and the first main vertical beam 7 are assembled and connected.

[0033] In this embodiment, the two adjacent second main vertical beams 8 or the second main vertical beam 8 and the first main vertical beam 7 are assembled and connected by a connecting plug-in 19; the specific structure of the connecting plug-in 19 includes an insert 192 and an intermediate plate 191. The insert 192 is inserted into the cavity of the two adjacent second main vertical beams 8 or the second main vertical beam 8 and the first main vertical beam 7 to achieve a butt connection. The intermediate plate 191 is fixed to the outer wall of the insert 192. When the insert 192 is inserted into the cavity, the second main vertical beam 8 and the first main vertical beam 7 abut against the intermediate plate 191. The insert 192 is provided with a bolt hole 193 that can be penetrated by a screw. The first main vertical beam 7 and the second main vertical beam 8 are respectively fastened to the insert 192 using bolts, thereby achieving the connection of the assembled cabinet 2.

[0034] In another implementation of this embodiment, Figure 2 and Figure 3 As shown, several main beams 9 are installed in the basic cabinet 1. Rollers 17 are installed on the side walls of the mother modules 3. The rollers 17 are connected to the main beams 9 in a rolling manner. The main beams 9 are provided with fixings for the rollers 17. Each mother module 3 is moved on the main beams 9 by the rollers 17, ensuring linearity when moving forward and backward and facilitating dragging and replacement.

[0035] Furthermore, a notch 11 is provided on the front side of the main crossbeam 9. A slot 12 extends from the notch 11 toward the door of the base cabinet 1. A roller 17 is locked by a fixing member after entering the slot 12. When the mother module 3 moves to a predetermined position, the roller 17 sinks into the notch 11. Further force is applied to the mother module 3 to insert the roller 17 into the slot 12. At this point, the roller 17 is locked by the fixing member.

[0036] The fixing member includes a back plate 14 fixed to the side wall of the slot 12, and a locking bolt 15 that passes through the back plate 14 and is fixed to the roller 17. The locking bolt 15 passes through the back plate 14 and is connected to the bolt hole reserved on the shaft of the roller 17. The back plate 14 is curved to accommodate the end portion of the roller 17.

[0037] The inner side of the main beam 9 is provided with a lap beam 10, and when the roller 17 is locked by the fixing member, the female module 3 is seated on the lap beam 10 (as shown in FIG. Figure 3 As shown). This makes the placement of the mother module 3 more stable and reduces the bearing force of the roller 17.

[0038] like Figure 3 As shown, the side of the notch 11 away from the latch 12 extends toward the top of the main beam 9 to form a continuously curved surface 13. The function of this curved surface is to apply force to the mother module 3 when removing the mother module 3 so that the roller 17 can move along the curved surface 13 to the top of the main beam 9 to remove the mother module 3.

[0039] like Figure 1 and Figure 4 As shown, the outer side of the main crossbeam 9 is provided with an outer back panel 16 capable of fixing the side panels; the side panels include the basic cabinet side panels 6 and the side panels 5. The side panels 5 cover one side of the notch 11. The basic cabinet side panels 6 are fixed to the basic cabinet 1; one end of the side panel 5 is hinged to the first main vertical beam 7, and the other end is connected to the basic cabinet side panel 6 via a letter lock 18. In order to improve the convenience of operation, when in use, the letter lock 18 can be directly opened and then the side panel 5 can be opened, and then the locking bolt 15 can be fixed or removed.

[0040] Working Principle: When assembling submodule 4, install it in assembly cabinet 2, and fix assembly body 2 to the top of base cabinet 1. During assembly, insert tube 192 is inserted into the cavity between two adjacent second main vertical beams 8 or the cavity between the second main vertical beam 8 and the first main vertical beam 7 to achieve a butt connection. Bolts are used to fasten the first and second main vertical beams 7, 8, to the insert tube 192, respectively, to achieve the connection of assembly cabinet 2.

[0041] To replace any of the mother modules 3, unlock the letter locks 18, open the side panels 5, and then remove the locking bolts 15. Apply force to the mother module 3, causing the roller 17 to move along the curved surface 13 to the top of the main beam 9, allowing the mother module 3 to be removed. During installation, overlap the roller 17 on the main beam 9 and push it until it fits into the slot 12. The mother module 3 is now seated on the overlapping beam 10. Insert the locking bolts 15 through the back panel 14 and connect them to the bolt holes reserved on the roller 17 shaft. Then, close the side panels 5.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
