Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical cabinet technology, specifically a GGD double-sided cabinet. Background Technology

[0002] GGD cabinets, or AC low-voltage distribution cabinets, are suitable for power distribution in power plants, substations, factories, and mines. GGD cabinets have advantages such as reasonable structure, convenient installation and maintenance, good protection performance, large capacity, strong segmentation capability, strong dynamic stability, and wide applicability of electrical schemes.

[0003] Traditionally, when designing a U-shaped box-type substation, GGD low-voltage distribution cabinets are often arranged back to back, which can save space inside the substation to a certain extent. However, when two GGD low-voltage distribution cabinets are arranged back to back, the installation areas of the two cabinets are independent and difficult to adjust, and the space behind each other cannot be utilized, which limits the space utilization rate inside the GGD cabinet and causes serious waste of space inside the cabinet. Utility Model Content

[0004] The purpose of this utility model is to make up for the shortcomings of the existing technology and provide a GGD double-sided cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A GGD double-sided cabinet includes two support frames, the corners of which are detachably connected by crossbars. The two support frames and several crossbars form a square cabinet support. The top, bottom and one of the opposite sides of the cabinet support are detachably connected to a top wall, a bottom wall and an outer wall, respectively. The other two opposite sides of the cabinet support are respectively provided with cabinet doors, forming a double-sided cabinet structure.

[0007] The cabinet structure has an adjustable positioning component and a first mounting plate inside. The positioning component and the first mounting plate are detachably connected, and the height of the first mounting plate is less than the height of the cabinet structure, so that two interconnected and relatively adjustable installation areas are formed inside the cabinet structure through the first mounting plate, thereby improving the utilization of space.

[0008] Furthermore, a number of first mounting holes are provided on each of the four side walls inside the support frame, and the number of first mounting holes are distributed at equal distances along the side walls of the support frame.

[0009] The positioning component includes two support columns, which are detachably connected to the inner side of the corresponding support frame. The support columns and the corresponding support frame are detachably connected through first mounting holes, so that the support columns can be installed in the corresponding positions through a number of first mounting holes.

[0010] Furthermore, several second mounting holes are provided on both sides of the support column, and the several second mounting holes are arranged at equal intervals along the support column;

[0011] Several mounting brackets are installed between the side of the support column and the inner side of the support frame. The two ends of the mounting brackets are detachably connected to the corresponding first mounting hole and second mounting hole, so that the height between two adjacent mounting brackets can be adjusted and fixed through the corresponding first mounting hole and second mounting hole.

[0012] At least one set of two opposing mounting brackets on the two support columns are detachably connected to both sides of the first mounting plate so that the first mounting plate can be fixed by the mounting brackets of corresponding height.

[0013] Furthermore, the mounting bracket has several third mounting holes on the side closest to the interior of the cabinet structure, and the third mounting holes are evenly distributed along the mounting bracket. A second mounting plate is detachably connected to the corresponding third mounting hole for installing electrical components.

[0014] Furthermore, a ventilation hole is provided on one side of the cabinet door, and a dustproof screen can be detachably connected to the cabinet door at the ventilation hole to serve the purpose of ventilation and dust prevention.

[0015] Furthermore, ventilation holes are provided at the top of the top wall, and a top cover with filter holes is also provided at the top of the top wall to allow heat to escape from the cabinet structure.

[0016] Furthermore, an adjustment component is provided inside the top cover, and the adjustment component is located at the ventilation hole to adjust the size of the ventilation hole;

[0017] The adjustment assembly includes a rack connected to the top of the top wall. Two toothed rings are symmetrically meshed on the top of the rack. The inner sides of the two toothed rings are respectively fixedly sleeved on the outer sides of the corresponding rotating shafts. The two rotating shafts are connected by a flexible pad, which covers the top of the ventilation hole.

[0018] Both shafts are rotatably connected to a connecting frame at their ends. The end of the connecting frame away from the shaft is slidably connected to a groove on the side of the rack, which serves to limit the movement of the gear ring and the rack.

[0019] One side of the connecting frame is equipped with a telescopic structure, and the other side of the telescopic structure is connected to the rack to drive the connecting frame to slide along the rack.

[0020] Compared with existing technologies, the GGD double-sided cabinet has the following advantages:

[0021] This utility model uses a support frame, outer wall, top wall, bottom, and double cabinet doors to form a cabinet structure. A positioning component and a first mounting plate create two installation areas inside the cabinet structure, with the height of the first mounting plate being less than the height of the cabinet structure. This allows the two installation areas to connect, improving space utilization. It solves the problem that when two GGD low-voltage distribution cabinets are arranged back-to-back, the installation areas of the two cabinets are independent and difficult to adjust, making it impossible to utilize the space behind them, thus limiting the use of space inside the GGD cabinet and causing serious waste of internal space.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1-7As shown, this utility model provides a technical solution: a GGD double-sided cabinet, including two support frames 4, the corners of the two support frames 4 are detachably connected by crossbars, the two support frames 4 and several crossbars form a square cabinet support, the top, bottom and one opposite side of the cabinet support are detachably connected to a top wall 3, a bottom wall and an outer side wall 1 respectively, and the other two opposite sides of the cabinet support are respectively provided with cabinet doors 2, forming a double-sided cabinet structure; the cabinet structure is provided with an adjustable positioning component and a first mounting plate 8 inside, the positioning component and the first mounting plate 8 are detachably connected, and the height of the first mounting plate 8 is less than the height of the cabinet structure, so that two interconnected and relatively adjustable installation areas are formed in the cabinet structure through the first mounting plate 8, so as to improve the space utilization rate.

[0032] In use, the side of the support frame 4 is provided with a mounting groove 9, and the inside of the mounting groove 9 is provided with several fourth mounting holes. The two outer side walls 1 are detachably mounted on the support frame 4 through the fourth mounting holes. The support frame 4 and the crossbar are detachably connected to the corresponding top wall 3 and bottom wall, respectively. The cabinet door 2 is provided with a hinge that is detachably mounted on the support frame 4. The first mounting plate 8 is fixed in the appropriate position by the positioning component. The first mounting plate 8 is used to divide the interior of the cabinet structure into two installation areas to facilitate the installation of different electrical components. At the same time, the top and bottom of the first mounting plate 8 are left with the top wall 3 and the bottom wall, respectively, to form a channel to facilitate wiring or the installation of longer electrical components and improve the utilization of space.

[0033] Based on the two installation areas mentioned above, there are at least two installation methods. The first installation method is to combine the incoming line cabinet and the capacitor cabinet. The two cabinet doors 2 are one for the capacitor cabinet and one for the incoming line cabinet. The first mounting plate 8 is installed in an appropriate position to make full use of the space below the installation area of ​​the incoming line cabinet components to place the capacitors. The upper half of the cabinet is mainly used to arrange the incoming line cabinet frame circuit breaker, and the lower half of the cabinet is mainly used to arrange the capacitors of the capacitor cabinet. This makes full use of the internal space of the cabinet and improves the space utilization rate of the cabinet.

[0034] The second installation method involves a combination of outgoing line cabinets. In this method, cabinet door 2 is the door 2 of the outgoing line cabinet. Electrical components of two outgoing line cabinets are installed in two installation areas respectively. Then, the main busbar is located in the middle of the top of the cabinet, and isolating switches are installed on both sides. Taking advantage of the interconnection between the two installation areas, the main busbar can be tilted to both sides at a certain angle to connect the cables to the isolating switches on both sides, which greatly saves the use of the main busbar.

[0035] Several first mounting holes are provided on the four side walls inside the support frame 4, and the several first mounting holes are distributed at equal intervals along the side walls of the support frame 4; the positioning component includes two support columns 6, which are detachably connected to the inner side of the corresponding support frame 4, and the support columns 6 and the corresponding support frame 4 are detachably connected through the first mounting holes, so that the support columns 6 can be installed in the corresponding positions through the several first mounting holes; in use, the position of the support columns 6 can be adjusted through the several first mounting holes to facilitate the division of the internal space of the cabinet structure, improve the space utilization, and at the same time support the support frame 4.

[0036] Several second mounting holes are provided on the opposite side walls of the support column 6, and the several second mounting holes are arranged at equal intervals along the support column 6; several mounting brackets 7 are installed between the side of the support column 6 and the inner side of the support frame 4, and the two ends of the mounting brackets 7 are detachably connected to the corresponding first mounting holes and second mounting holes, so as to adjust and fix the height between two adjacent mounting brackets 7 through the corresponding first mounting holes and second mounting holes; at least one set of two opposite mounting brackets 7 on the two support columns 6 are detachably connected to the two sides of the first mounting plate 8, so as to fix the first mounting plate 8 through the mounting brackets 7 of the corresponding height; in use, it is convenient to select the mounting brackets 7 of the corresponding height to fix the first mounting plate 8, and adjust the height of the first mounting plate 8 and the distance between the top and bottom channels.

[0037] The mounting bracket 7 has several third mounting holes on one side near the interior of the cabinet structure, and these third mounting holes are evenly distributed along the mounting bracket 7. A second mounting plate is detachably connected to each of the corresponding third mounting holes for installing electrical components. In use, the mounting bracket 7 has various lengths. The appropriate mounting bracket 7 is selected according to the distance between the support column 6 and the support frame 4, which enhances the stability between the support column 6 and the support frame 4, and provides an installation position for the second mounting plate. The second mounting plate is installed in the corresponding position of the corresponding installation area. If necessary, holes can be drilled in the first mounting plate 8 to install electrical components.

[0038] A ventilation hole is provided on one side of the cabinet door 2. A dustproof net 5 is detachably connected to the ventilation hole of the cabinet door 2, which serves the purpose of ventilation and dust prevention. A ventilation hole is provided on the top of the top wall 3, and a top cover 10 with filter holes is also provided on the top of the top wall 3 to allow heat to flow out from the cabinet structure. There are two configurations for the top wall 3 during use: one without ventilation holes, in which case the cabinet dissipates heat through the ventilation holes on the cabinet door 2; the other for indoor use, in which ventilation holes are provided on the top to facilitate the exhaust of heat from the top. The side of the top cover 10 is inclined, and the filter holes are located on the inclined surface, with the axis of the filter holes horizontally distributed to facilitate the exhaust of heat.

[0039] An adjustment assembly is provided inside the top cover 10, and the adjustment assembly is located at the ventilation hole for adjusting the size of the ventilation hole. The adjustment assembly includes a rack 15, which is connected to the top of the top wall 3. Two toothed rings 13 are symmetrically meshed on the top of the rack 15. The inner sides of the two toothed rings 13 are respectively fixedly sleeved on the outer sides of the corresponding rotating shafts 12. The two rotating shafts 12 are connected by a flexible pad 11, which covers the top of the ventilation hole. A connecting frame 17 is rotatably connected to the ends of the two rotating shafts 12. The end of the connecting frame 17 away from the rotating shaft 12 is slidably connected to the slide groove on the side of the rack 15 for limiting the toothed rings 13 and the rack 15. A telescopic structure 16 is provided on one side of the connecting frame 17, and the other side of the telescopic structure 16 is connected to the rack 15 for driving the connecting frame 17 to slide along the rack 15.

[0040] In use, the telescopic structure 16 is an electric telescopic push rod. There are two racks 15, which are detachably fixed to the top wall 3 with screws. The two racks 15 are symmetrically distributed on both sides of the ventilation hole, and each rack 15 is provided with a sliding groove and two electric telescopic push rods. The two electric telescopic push rods are mounted at both ends by brackets and are used to drive the two connecting frames 17. The two connecting frames 17 on one rack 15 are symmetrically arranged. The end of the connecting frame 17 near the rotating shaft 12 is provided with an arc-shaped plate, which is fixedly connected to the pressure limiting frame 14. One end of the pressure limiting frame 14 is sleeved on the end of the rotating shaft 12 in a ring shape to further support the rotating shaft 12. The middle part of the pressure limiting frame 14 extends downward to limit the flexible pad 11 between the two rotating shafts 12 to the top of the top wall 3. In order to prevent the pressure limiting frame 14 from moving the flexible pad 11 during movement, the bottom of the pressure limiting frame 14 is flush with the top wall. The distance between 3 is slightly greater than the thickness of the flexible pad 11, so that the flexible pad 11 in the middle fits against the top wall 3 under its own weight. The flexible pad 11 is made of rubber. During operation, when the ventilation hole is gradually opened to one side, the electric telescopic push rod on one side works, causing the electric telescopic push rod to drive the corresponding connecting frame 17 to move. The connecting frame 17 further drives the toothed ring 13 and the rotating shaft 12 to move. Since the toothed ring 13 and the rack 15 mesh, the toothed ring 13 drives the rotating shaft 12 to rotate, causing the rotating shaft 12 to roll up the flexible pad 11 and move towards the other side of the rotating shaft 12, gradually opening the ventilation hole. When it is necessary to open both sides of the ventilation hole, first move the rotating shaft 12 on one side to the appropriate position, then stop the movement, and then drive the rotating shaft 12 on the other side to move through another electric telescopic push rod, thereby opening on both sides. Adjust the size of the ventilation hole opening to control the ventilation volume.
