[0002] A switchgear is an electrical device. External power lines first enter the main control switch inside the cabinet, then the branch control switches. Each branch circuit is configured according to its needs, such as instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments, and high-voltage busbars, such as in power plants. Some also have underfrequency load shearing for the protection of key equipment. The main function of switchgear is to open, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components inside a switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices. According to the cabinet structure, it can be divided into open-type switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear. According to the voltage level, it can also be divided into high-voltage switchgear, medium-voltage switchgear, and low-voltage switchgear. It is mainly suitable for various occasions such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential areas, and high-rise buildings.

[0003] Traditional switchgear mostly adopts a fixed shelf structure design, with the position and number of each shelf determined during manufacturing. It is difficult to make flexible adjustments according to actual usage needs. Some complex industrial power systems may require the installation of various numbers of electrical components such as circuit breakers, relays, and fuses. Since the number of shelves and spatial layout of traditional switchgear are fixed, they often cannot meet the reasonable installation of a large number of electrical components. In some places with relatively low power demand, fixed-structure switchgear results in wasted space, leading to idle resources and increased costs.

[0004] Therefore, a switchgear integrated device with a multi-layer modular structure is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a switch cabinet integrated device with a multi-layer modular structure, which has the advantage of being able to flexibly adjust the shelves according to actual usage, avoiding the inconvenience caused by insufficient installation space and affecting the spatial layout.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switch cabinet integrated device with a multi-layer modular structure, comprising a switch cabinet body, wherein multi-layer structural components are mounted on the surface of the switch cabinet body;

[0007] The multi-layer structure component includes shelves. Several shelves are arranged inside the switch cabinet body. Support plates are symmetrically installed on the upper surface of the shelves. Connecting rods are slidably connected in the grooves opened inside the support plates. One end of the connecting rod passes through the support plate and extends to the outside of the support plate, and is connected to the plug block arranged outside the support plate. The plug block is inserted into the slot opened on the surface of the switch cabinet body. Insert strips are installed on both sides of the shelves. The surface of the switch cabinet body has positioning grooves adapted to the insert strips. The insert strips are inserted into the positioning grooves. Auxiliary disassembly and assembly components are installed on the surface of the shelves.

[0008] Preferably, the inside of the switch cabinet body is provided with several positioning slots, and the slots opened on the surface of the switch cabinet body correspond one-to-one with these positioning slots.

[0009] Preferably, a limit block is installed on the surface of the connecting rod, and a return spring is sleeved on the surface of the connecting rod. One end of the return spring is connected to the limit block, and the other end of the return spring is connected to the support plate.

[0010] Preferably, the specific number of the shelves can be flexibly adjusted according to the actual situation.

[0011] Preferably, the side surface of the insert block away from the support plate has a serrated plate one, and a serrated plate two is installed in the slot opened on the surface of the switch cabinet body, with the serrated plate one and the serrated plate two engaging.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a switch cabinet integrated device with a multi-layer modular structure, including a switch cabinet body 1, and a multi-layer structural component 2 installed on the surface of the switch cabinet body 1.

[0025] The multi-layer structure component 2 includes shelf plates 21. Several shelf plates 21 are arranged inside the switch cabinet body 1. Support plates 22 are symmetrically installed on the upper surface of each shelf plate 21. Connecting rods 23 are slidably connected within grooves opened inside the support plates 22. One end of the connecting rod 23 passes through the support plate 22 and extends to the outside of the support plate 22, connecting with an insert block 24 located outside the support plate 22. The insert block 24 is inserted into slots opened on the surface of the switch cabinet body 1. Insert strips 25 are installed on both sides of each shelf plate 21. The surface of the switch cabinet body 1 is opened with… There is a positioning groove that matches the insertion strip 25. The insertion strip 25 is inserted into this positioning groove. The surface of the shelf 21 is equipped with an auxiliary disassembly and assembly component 3. The number and position of the shelf 21 can be flexibly adjusted according to actual needs, breaking through the limitations of the traditional fixed shelf 21 structure of switch cabinets. It can provide sufficient and reasonable installation space for various electrical components such as circuit breakers, relays, and fuses. In places with low power demand, the number of shelves 21 can be reduced to avoid space waste, improve the space utilization rate of the switch cabinet body 1, and reduce resource idleness and costs.

[0026] Specifically, the switch cabinet body 1 has several positioning slots pre-drilled inside, and the slots on the surface of the switch cabinet body 1 correspond one-to-one with these positioning slots, thereby enabling adjustment of the spacing between the upper and lower layers of the shelf 21.

[0027] like Figures 1 to 5 As shown, a limiting block 26 is installed on the surface of the connecting rod 23, and a return spring 27 is sleeved on the surface of the connecting rod 23. One end of the return spring 27 is connected to the limiting block 26, and the other end of the return spring 27 is connected to the support plate 22, so that the position of the connecting rod 23 can be limited, and the return spring 27 can be compressed, which facilitates the operator to install the shelf 21.

[0028] Furthermore, the specific number of shelves 21 can be flexibly adjusted according to the actual situation.

[0029] It is worth noting that the side surface of the plug block 24 away from the support plate 22 has a serrated plate 28, and a serrated plate 29 is installed in the slot opened on the surface of the switch cabinet body 1. The serrated plate 28 and the serrated plate 29 mesh with each other, thereby stabilizing the position of the shelf 21 after installation and further improving the stability of the device.

[0030] like Figures 1 to 5As shown, the auxiliary disassembly and assembly component 3 includes an adjustment plate 31. The adjustment plate 31 is installed between two support plates 22. The other end of the connecting rod 23 passes through the support plate 22 and is slidably connected in the adjustment groove opened inside the adjustment plate 31. It is connected to the handle 32 set in the adjustment groove. One end of the handle 32 extends to the outside of the adjustment groove. By driving the connecting rod 23 to slide in the adjustment groove of the adjustment plate 31 through the handle 32, the insertion and removal of the plug 24 can be easily controlled. When disassembling, simply pull the handle 32 to pull out the plug 24, and the shelf 21 can be taken out from the switch cabinet body 1. This greatly simplifies the disassembly and assembly process of the shelf 21 and improves the installation and maintenance efficiency.

[0031] It is worth emphasizing that the surface of the handle 32 is provided with anti-slip texture, which can increase the friction when the operator holds it, prevent slippage during operation, and ensure safe and stable disassembly and assembly operations.

[0032] Working principle and process: First, determine the number and installation position of the required shelves 21 according to the actual electrical component installation requirements. Then, align the inserts 25 on both sides of the shelf 21 with the positioning grooves on the surface of the switch cabinet body 1 and insert them smoothly along the direction of the positioning grooves to initially fix the shelf 21 in the switch cabinet body 1.

[0033] Then, squeeze the two handles 32 so that they come closer to each other. The handles 32 slide in the adjustment groove on the surface of the adjustment plate 31. At this time, the handles 32 drive the connecting rod 23 to slide in the support plate 22 and the adjustment plate 31. At the same time, the limit block 26 compresses the return spring 27, causing the insert block 24 to move towards the support plate 22. When the shelf 21 is completely inserted into the switch cabinet body 1, the handles 32 are released. Under the elastic force of the return spring 27, the connecting rod 23 drives the insert block 24 to move outward. The insert block 24 is inserted into the corresponding slot on the surface of the switch cabinet body 1. At this time, the serrated plate 28 on the insert block 24 meshes with the serrated plate 29 in the slot of the switch cabinet body 1, further stabilizing the position of the shelf 21 and completing the installation and fixation of the shelf 21 in the switch cabinet body 1. Different numbers of shelves 21 can be selected according to the actual use. Then, the distance between the shelves 21 can be adjusted according to the slots in different positions to flexibly adapt and adjust the position and number of shelves 21.

[0034] When disassembling, first repeatedly squeeze the two handles 32. The handles 32 slide in the adjustment groove on the surface of the adjustment plate 31. At this time, the handles 32 drive the connecting rod 23 to slide in the support plate 22 and the adjustment plate 31. At this time, the limit block 26 compresses the reset spring 27, causing the insert 24 to move towards the support plate 22. The serrated plate 28 on the insert 24 separates from the serrated plate 29 in the slot of the switch cabinet body 1 until the insert 24 is completely removed from the slot on the surface of the switch cabinet body 1. After the insert 24 is removed from the slot, hold the shelf 21 and pull out the insert strips 25 on both sides of the shelf 21 from the positioning groove on the surface of the switch cabinet body 1. The shelf 21 can then be removed from the switch cabinet body 1.

[0035] When it is necessary to add a shelf 21, repeat the above shelf 21 installation process and install the new shelf 21 into the appropriate position inside the switch cabinet body 1 as required; when it is necessary to reduce a shelf 21, repeat the above shelf 21 disassembly process and remove the excess shelf 21 from the switch cabinet body 1, thereby flexibly meeting the diverse needs of different power systems for the internal space layout and electrical component installation of the switch cabinet body 1.
