Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to an intelligent integrated DC power supply cabinet. Background Technology

[0002] In the field of smart grids, grid-level integrated DC power supply cabinets, as core power supply guarantee equipment for power systems, need to be transported over long distances to various outdoor and industrial park application sites. To optimize logistics costs and improve the efficiency of bulk transportation, multiple power supply cabinets are often stacked together in the transport vehicle for unified transportation. However, during long-distance transportation, the vehicle is prone to continuous bumps and high-frequency vibrations. In addition, the cabinets are susceptible to collisions and friction without protection, making vulnerable parts such as the protruding outer edge of the cabinet top cover prone to paint scratches and structural damage. Therefore, professional flexible protective measures must be taken for key parts of the cabinet before transportation. This is crucial to ensuring the structural and appearance integrity of the equipment after transportation and is also a mandatory process requirement for the long-distance transportation of such core power supply equipment.

[0003] In related technologies, before transporting the power cabinet, workers use bubble wrap or foam as a flexible protective layer to tightly wrap the protruding outer edge area of ​​the top cover. The cushioning properties of the bubble wrap absorb collisions and vibrations during transport, reducing frictional damage between adjacent cabinets. After the flexible protective layer is wrapped, its edges are secured with tape. This prevents the layer from loosening or falling off during transport and further seals it, improving its waterproof and dustproof performance.

[0004] Once the power cabinet arrives at its destination, the flexible protective layer (bubble wrap or foam) needs to be removed to begin installation. This removal process necessitates tearing off the adhesive tape used for securing the cabinet. Because this tape adheres to the painted surface of the cabinet and top cover for extended periods, and is affected by vibrations and moisture during transport, its adhesion to the paint surface increases significantly. Forcibly tearing it off easily peels off the surface markings and coatings, resulting in blurred or damaged markings on the cabinet or top cover. Damaged markings not only affect the equipment's appearance but also interfere with subsequent installation identification, maintenance, and inspection work, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent integrated DC power supply cabinet that solves the problems in the above-mentioned related technologies where the protective layer fixed by tape easily sticks to the paint surface and damages the cabinet markings and coating when it is removed.

[0006] The intelligent integrated DC power supply cabinet provided in this application adopts the following technical solution: An intelligent integrated DC power supply cabinet includes a cabinet body and a cabinet door rotatably mounted on the front side of the cabinet body. A top cover is fixed on the top surface of the cabinet body, and several heat dissipation vents are opened on the left and right vertical sides. A control plate that can slide up and down is slidably mounted on the left and right vertical sides of the cabinet body, and there is a clearance between the control plate and the vertical sides of the cabinet body. The control plate can be moved down to a supported state flush with the bottom surface of the cabinet body and moved up to a limited state close to the top cover. A control notch is opened on the top surface of the control plate, and two coaxial locking rods are detachably mounted on the bottom wall of the control notch. A limiting component is provided to lock the sliding state of the control plate. An elastic fastener is detachably mounted on the top surface of the locking rods. The elastic fastener elastically clamps the edge of the wrapped flexible protective layer when the control plate is in the limited state.

[0007] By adopting the above technical solution, the control panel can be adjusted up and down to move to the limit position during transportation. Elastic fasteners are used to clamp and fix the edge of the flexible protective layer, which effectively prevents the tape from sticking to the cabinet and the top cover paint, and prevents damage to the surface markings and coatings when the tape is removed. This ensures the integrity of the equipment's appearance and the clarity of the markings. At the same time, when the control panel is moved down to the support position, the installation stability of the power cabinet can be enhanced, taking into account both transportation protection and installation firmness, and adapting to the needs of outdoor use.

[0008] Optionally, the elastic fastener includes a fastening rod with one end rotatably connected to the top surface of the locking rod, and an elastic torsion spring disposed at the junction of the fastening rod and the locking rod. The elastic torsion spring drives the fastening rod to rotate downward to a fastened state that is parallel to the locking rod and abuts against the top surface. When the fastening rod is in the fastened state, the top surface of the fastening rod is flush with the top surface of the control plate.

[0009] By adopting the above technical solution, the elastic torsion spring drives the fastening rod to a tight state parallel to the locking rod, which can stably clamp the edge of the flexible protective layer. The fixing effect is reliable and the disassembly is convenient. It can be loosened without additional tools, avoiding damage to the protective layer. At the same time, the top surface of the fastening rod is flush with the top surface of the control panel, which can reduce the possibility of the fastening rod being bumped or worn during transportation and use, extending its service life. The structural design is compact and does not affect the overall layout of the equipment or the ease of operation.

[0010] Optionally, the limiting component includes an elastic limiting rod with elastic elongation properties and one end of which is vertically fixedly connected to the end face of the two locking rods that are far apart from each other. A first slot is provided on the upper part of the left and right sides of the cabinet, and a second slot is provided on the lower part. When the control plate is in the limiting state, the end of the elastic limiting rod is inserted into the first slot, and when the control plate is in the supporting state, it is inserted into the second slot.

[0011] By adopting the above technical solution, and using a structure that combines an elastic limit rod with a slot, the limit and support states of the control board can be quickly locked. The operation is simple, the positioning is precise, and no complex fixing steps are required. The elastic extension performance of the elastic limit rod can adapt to the position adjustment during the sliding process of the control board, ensuring stable limiting of the control board during transportation and firm support during use. This effectively prevents accidental sliding of the control board and improves the structural stability during equipment transportation and installation.

[0012] Optionally, a first inclined surface is provided at the outer edge of the end of the elastic limiting rod away from the locking rod.

[0013] By adopting the above technical solution, the elastic limit rod plays a guiding role when sliding up and down on the control panel and engaging in the slot, reducing the frictional resistance between the limit rod and the slot, so that the limit rod can smoothly engage in the corresponding first or second slot, reducing the difficulty of operation.

[0014] Optionally, two elastic positioning rods with elastic telescopic properties are rotatably installed on the vertical side of the cabinet, located below the heat dissipation vents. The rotating surfaces of the elastic positioning rods are parallel to the left and right sides of the cabinet, and a limit slot is provided on the top surface of the elastic positioning rod. When the control plate is in the limit state, the two elastic positioning rods can rotate towards each other to a coaxial storage state and can be detached and fixed. When the control plate is in the support state, the elastic positioning rods can rotate away from each other to a vertically downward limit state, and the lower end of the elastic positioning rod is inserted into the limit slot at this time.

[0015] By adopting the above technical solution, the flexible positioning rods can flexibly switch according to different states of the control board. During transportation, they can be rotated in opposite directions for storage and fixation, preventing damage caused by random swinging during transport and reducing space occupation. When in use, they can be rotated back to back until vertically downward, with the lower end inserted into the limit slot, further enhancing the stability of the control board's support state and improving the wind and vibration resistance of the power cabinet after outdoor installation. Its flexible telescopic performance can adapt to different positioning requirements, with a flexible structure that balances convenient storage with robust support.

[0016] Optionally, a positioning block and a positioning slot are fixed on the end face of the elastic positioning rod away from the cabinet; when the two elastic positioning rods are in the retracted state, the positioning block on one of them is inserted into the positioning slot on the other.

[0017] By adopting the above technical solution, the two elastic positioning rods achieve detachable fixation in the stored state through the cooperation of positioning blocks and positioning slots. The fixing method is simple and reliable, requiring no additional fixing parts and is convenient to operate. It can effectively prevent the elastic positioning rods from coming out of the stored state due to vibration and bumps during transportation, avoid them swinging randomly and colliding with the cabinet and control panel to prevent damage, ensure the integrity of the components during transportation, and facilitate subsequent unlocking and unfolding, improving ease of use.

[0018] Optionally, a fixed plate and a flexible protective curtain fixed to one side of the fixed plate are provided below the control board. Two fixing blocks are fixed on the side edge of the fixed plate facing the flexible protective curtain. A receiving cavity is opened on the bottom surface of the control board. A receiving groove is opened at the opening edge of the receiving cavity. A receiving slot is opened on the top wall of the receiving groove. A fixing slot is opened on the outer periphery of the elastic positioning rod. When the control board is in the supported state, the flexible protective curtain is folded and stored in the receiving cavity. At this time, the fixed plate is placed in the receiving groove, and the fixing blocks are inserted into the receiving slots. When the control board is in the limited state, the flexible protective curtain is extended from the receiving cavity. The fixing blocks move down with the fixed plate and are inserted into the fixing slots. At this time, the flexible protective curtain protects the heat dissipation vents.

[0019] By adopting the above technical solution, the flexible protective curtain can flexibly switch between storage and display states according to the control panel status. When in use, it is folded and stored in the accommodating cavity, without occupying extra space or affecting the normal heat dissipation of the vents. During transportation, it is unfolded to protect the vents, effectively preventing external dust and impurities from entering the cabinet through the vents and protecting the internal electrical components. The cooperation between the fixing plate and the fixing block enables the protective curtain to be quickly fixed and stored. The structural design is reasonable, balancing protection and ease of use.

[0020] Optionally, a second inclined surface is provided on the outer edge of the side of the fixing block away from the fixing plate.

[0021] By adopting the above technical solution, the second inclined surface of the outer edge of the fixed plug can play a guiding role when the fixed plug is inserted into the receiving slot or the fixed slot, reducing the difficulty of insertion, enabling the fixed plug to be smoothly inserted into the corresponding slot, and improving the operating efficiency.

[0022] Optionally, the control panel has extension plates vertically fixed at both ends, which respectively abut against and slide against the front and rear edges of the cabinet. The control panel can slide to a receiving state in the middle of the vertical side of the cabinet, and a clearance slot is provided on the bottom surface of the extension plate. When the control panel is in the receiving state, the elastic positioning rod can rotate to an inclined upward state, and the positioning block on the elastic positioning rod is then inclinedly inserted into the clearance slot. A flexible collection bag with an upward opening is provided on the outside of the cabinet. The end of the locking rod near the elastic limiting rod is rotatably connected to the bottom wall of the control notch, and a locking slot is provided on the top surface of the locking rod. When the control panel is in the receiving state, the two locking rods can rotate to a parallel receiving state in a direction away from the cabinet. At this time, the two fixing blocks on the fixing plate can be dislodged from the receiving slot and inserted into the locking slot. The elastic fastener clamps and fixes the opening edge of the flexible collection bag.

[0023] By adopting the above technical solution, the control board gains a new receiving state, adapting to maintenance scenarios. The elastic positioning rod tilts to support the control board, and the locking rod, after unfolding, is fixed by a fixing block, forming a stable receiving structure. The flexible collection bag, secured by elastic fasteners, can centrally collect waste and garbage generated during maintenance, keeping the maintenance site clean and improving convenience. All components work together to achieve flexible switching between transportation, use, and maintenance states, offering comprehensive functionality and strong adaptability.

[0024] Optionally, a dovetail slider is fixedly provided on the extension plate, and dovetail grooves that slide in cooperation with the dovetail slider are provided on the front and back edges of the cabinet.

[0025] By adopting the above technical solution, the sliding cooperation between the dovetail slider and the dovetail groove enables precise sliding connection between the control panel and the cabinet. It has good guiding properties and can effectively prevent the control panel from deviating or shaking during the sliding process, ensuring the smoothness of the up and down sliding adjustment of the control panel.

[0026] In summary, this application includes the following beneficial technical effects: In this application, the control panel is adjusted by sliding up and down. During transportation, the control panel is moved up to the limit position, and the edge of the flexible protective layer is elastically clamped and fixed by elastic fasteners. This effectively prevents the tape from sticking to the cabinet and the paint surface of the top cover, and prevents damage to the surface markings and coatings when the tape is removed. This ensures the integrity of the equipment's appearance and the clarity of the markings. At the same time, when the control panel is moved down to the support position, the installation stability of the power cabinet can be enhanced. This balances transportation protection and installation firmness, and is suitable for outdoor use. Attached Figure Description

Detailed Implementation

[0029] The present application will be further described in detail below with reference to all the accompanying drawings. Example

[0030] Reference Figure 1 , Figure 2 and Figure 3 An intelligent integrated DC power supply cabinet includes a cabinet body 1, a cabinet door 2 rotatably mounted on the front side of the cabinet body 1, a top cover 11 fixed on the top surface of the cabinet body 1, and several heat dissipation vents 12 on the left and right vertical sides; control components 3 are provided on the left and right vertical sides of the cabinet body 1, the control components 3 include a control plate 31 that slides horizontally on the cabinet body 1 and can be adjusted up and down, and there is a clearance between the control plate 31 and the vertical side of the cabinet body 1; a control notch 311 is provided on the top surface of the control plate 31, and two coaxial locking rods 4 are detachably mounted on the bottom wall of the control notch 311, and a limiting component 5 is provided; elastic fasteners 6 are detachably mounted on the top surface of the locking rods 4. During the transportation of the power cabinet, the outer edge of the top cover 11 is first wrapped with a flexible protective layer. Then, the control board 31 is moved up to a limit position close to the top cover 11. The limit member 5 is used to fix the control board 31 in this position. Finally, the elastic fastener 6 is used to clamp the edge of the flexible protective layer that passes through the clearance gap. When the power cabinet is in use, the control board 31 is moved down to a support position flush with the bottom surface of the cabinet 1. The limit member 5 is used to fix the control board 31 in this position. At this time, the control board 31 is used to enhance the installation stability of the power cabinet.

[0031] Reference Figure 1 and Figure 2 The control panel 31 has extension plates 32 fixed vertically at both ends, which abut against and slide with the front and rear edges of the cabinet 1, respectively. The extension plates 32 are fixed with dovetail sliders 321. The front and back edges of the cabinet 1 are provided with dovetail grooves 13 that slide with the dovetail sliders 321, thereby realizing the sliding fit between the control panel 31 and the cabinet 1.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The elastic fastener 6 includes a fastening rod 61 with one end rotatably connected to the top surface of the locking rod 4, and an elastic torsion spring (not shown in the figure) located at the junction of the fastening rod 61 and the locking rod 4. The elastic torsion spring is a conventional elastic structure, which will not be described in detail here. Under normal conditions, the elastic torsion spring drives the fastening rod 61 to rotate downwards to a fastened state that is parallel to the locking rod 4 and abuts against the top surface. When the fastening rod 61 is in the fastened state, the top surface is flush with the top surface of the control plate 31, reducing the possibility of the fastening rod 61 being damaged by impact.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The limiting member 5 includes an elastic limiting rod 51 with elastic elongation properties and one end of which is perpendicularly fixed to the end face of the two locking rods 4 that are far away from each other. The upper part of the left and right sides of the cabinet 1 is provided with a first slot 14 and the lower part is provided with a second slot 15. The outer edge of the end of the elastic limiting rod 51 that is far away from the locking rod 4 is provided with a first inclined surface 511. When the control board 31 is in the limited position, the end of the elastic limit rod 51 is engaged in the first slot 14, thereby limiting and locking the control board 31 in this state; when the control board 31 is in the supported position, the end of the elastic limit rod 51 is engaged in the second slot 15, thereby limiting and locking the control board 31 in this state.

[0034] Reference Figure 6 and Figure 7The top surface of the elastic limiting rod 51 has a limiting slot 512. Two elastic positioning rods 16 with elastic telescopic properties are rotatably installed on the vertical side of the cabinet 1, located below the heat dissipation vent 12. The rotating surface of the elastic positioning rod 16 is parallel to the left and right sides of the cabinet 1. The elastic positioning rod 16 is a conventional elastic telescopic structure with an internal spring, which will not be described in detail here. A positioning plug 161 and a positioning slot 162 are fixed on the end face of the elastic positioning rod 16 away from the cabinet 1. When the control board 31 is in the supported state (i.e., power cabinet application), the elastic positioning rod 16 can rotate to the vertically downward limit state. The positioning block 161 on the lower end of the elastic positioning rod 16 is inserted into the limit slot 512 at this time, so as to enhance the installation stability of the control board 31 in this state by using the elastic positioning rod 16. When the control panel 31 is in the limit state (i.e., when the power cabinet is being transported), the two elastic positioning rods 16 can rotate towards each other to a coaxial storage state. At this time, the positioning block 161 on one of the two elastic positioning rods 16 is inserted into the other upper positioning slot 162, thereby limiting and locking the state of the two elastic positioning rods 16 at this time, reducing the possibility of the elastic positioning rods 16 swinging randomly during transportation.

[0035] Reference Figure 8 , Figure 9 and Figure 10 Below the control panel 31, there is a protective component 7, which includes a fixed plate 71 and a flexible protective curtain 72 fixed to one side of the fixed plate 71. Two fixing blocks 73 are fixed on the side edge of the fixed plate 71 facing the flexible protective curtain 72, and a second inclined surface 731 is provided on the outer edge of the side of the fixing blocks 73 away from the fixed plate 71. A receiving cavity 312 is opened on the bottom surface of the control panel 31. A receiving groove 313 is opened at the opening edge of the receiving cavity 312. A receiving slot 314 is opened on the top wall of the receiving groove 313. A fixing slot 163 is opened on the outer periphery of the elastic positioning rod 16. When the control board 31 is in the supported state (i.e., the power cabinet application), the flexible protective curtain 72 is folded and stored in the accommodating cavity 312, the fixing plate 71 is placed in the accommodating recess 313, and the fixing block 73 is inserted into the accommodating slot 314, thereby folding and storing the fixing plate 71 and the flexible protective curtain 72. When the control board 31 is in the limit state (that is, when the power cabinet is being transported), the flexible protective curtain 72 extends out from the accommodating cavity 312, and the fixing block 73 moves down with the fixing plate 71 and is inserted into the fixing slot 163. At this time, the flexible protective curtain 72 is used to protect the heat dissipation vent 12, reducing the possibility of external impurities entering the cabinet 1 from the heat dissipation vent 12 during transportation.

[0036] Reference Figure 11 , Figure 12 and Figure 13The control panel 31 can slide to a receiving state in the middle of the vertical side of the cabinet 1. A clearance slot 322 is provided on the bottom surface of the extension plate 32. When the control panel 31 is in the receiving state, the elastic positioning rod 16 can rotate to an inclined upward state. The positioning block 161 on the elastic positioning rod 16 is then inclined and inserted into the clearance slot 322 to limit and support the control panel 31 in this state. A flexible collection bag 8 with an upward opening is provided on the outside of the cabinet 1. The end of the locking rod 4 near the elastic limiting rod 51 is rotatably connected to the bottom wall of the control notch 311. A locking slot 41 is provided on the top surface of the locking rod 4. During the later maintenance of the power cabinet, the control board 31 is adjusted to the receiving state in advance, and then the two locking rods 4 are rotated to the receiving state in a parallel direction away from the cabinet 1. Then, the two fixing blocks 73 on the fixing plate 71 are removed from the receiving slot 314 and inserted into the locking slot 41. In this way, the combined structure of the fixing plate 71 and the fixing blocks 73 limits and locks the receiving state of the two locking rods 4. Finally, the opening edge of the flexible collection bag 8 is clamped and fixed by the elastic fastener 6.

[0037] The implementation principle of this application embodiment is as follows: During transportation, the outer edge of the top cover 11 is first wrapped with a flexible protective layer, and the control board 31 is moved up to be close to the top cover 11. The elastic limiting rod 51 is then inserted into the first slot 14 to lock the control board 31 in a limited position. Then, the elastic fastener 6 is used to clamp the edge of the flexible protective layer that passes through the clearance gap. At the same time, the elastic positioning rod 16 is rotated to the storage position and fixed by the positioning plug 161 and the positioning slot 162. The flexible protective curtain 72 is then extended and inserted into the fixing slot 163 on the elastic positioning rod 16 by the fixing plug 73, thereby protecting the heat dissipation vent 12 and preventing bumps and impurities from entering during transportation.

[0038] In the application state, the control board 31 is moved down to be flush with the bottom surface of the cabinet 1, and the elastic limit rod 51 is locked into the second slot 15 to maintain the support state; the elastic positioning rod 16 is rotated to face downwards and the lower end is inserted into the limit slot 512 of the elastic limit rod 51 to enhance the stability of the control board 31; the flexible protective curtain 72 is folded and stored in the accommodating cavity 312, the fixing plate 71 is placed in the accommodating recess 313, and the fixing block 73 is inserted into the accommodating slot 314 without affecting the normal operation of the equipment.

[0039] During later maintenance, the control board 31 is adjusted to the middle receiving position of the cabinet 1, the elastic positioning rod 16 is rotated to tilt upwards, and the positioning block 161 is inserted into the clearance slot 322 to support and limit the control board 31; the locking rod 4 is rotated to the parallel receiving position, the fixing block 73 of the fixing plate 71 is dislodged from the receiving slot 314 and inserted into the locking slot 41 on the locking rod 4, and finally the edge of the flexible collection bag 8 is clamped with the elastic fastener 6 to facilitate the collection of waste or other garbage generated during the maintenance operation.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
