Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, specifically to an integrated maintenance power supply box. Background Technology

[0002] With the increasing complexity and precision of power system maintenance, on-site operations in substations, distribution rooms, and other locations place higher demands on the portability, integration, and safety of maintenance equipment. Traditional power supply and tool management methods for maintenance typically employ a decentralized structure, requiring operators to carry separate uninterruptible power supplies, cable management devices, insulated tools, and testing instruments to the work site. This layout presents several problems: First, the dispersed storage of tools and power components leads to low transportation efficiency, frequent handling causes equipment damage, and time-consuming on-site setup affects maintenance timeliness. Second, the lack of unified storage devices for power cables makes them prone to tangling, knots, and even damage, posing safety hazards such as leakage and short circuits. Furthermore, existing control panels are often limited in function, lacking integrated designs with multiple output components, making it difficult to adapt to the power requirements of different equipment. Additional adapters or temporary wiring are required, increasing operational complexity and potentially leading to equipment violations due to incompatible interfaces.

[0003] In existing technologies, some improved power supply boxes have attempted to integrate certain functions, such as some portable power supply boxes with wheels. However, their storage space lacks modular partitioning, and the mixing of tools and power supplies can easily lead to messy internal wiring. Some products have added cable reels, but they lack adapter components suitable for different scenarios, and the control panel protection is insufficient. When the cover is closed, it cannot secure precision instruments, causing the equipment to shake and be damaged. More importantly, existing devices generally lack insulation protection accessories for high-voltage operations (such as built-in storage design for insulating gloves, discharge rods, etc.). Operators must carry such safety tools themselves, which can easily lead to omissions or improper use, further increasing operational risks.

[0004] The persistent existence of the aforementioned problems has led to low on-site maintenance efficiency, increased equipment management costs, and the potential for safety accidents or regulatory violations due to temporary wiring errors, inadequate insulation measures, and other reasons. Therefore, there is an urgent need for a highly integrated, fully functional, and standardized power supply box that conforms to standardized power maintenance procedures. This would address the pain points of equipment dispersion, operational redundancy, and safety hazards, and meet the standardized requirements of modern power maintenance operations.

[0019] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0020] like Figure 1 As shown, an integrated maintenance power supply box includes a box body 1, a top cover 2, and an operation panel 3 disposed inside the box body 1. The top cover 2 is hinged to the side of the box body 1 and fastened to the top of the operation panel. A storage space is provided inside the box body 1 below the operation panel 3. The storage space contains an uninterruptible power supply, an automatic cable reel, a stainless steel cable tray, insulating gloves, a high-voltage insulating mat, and a discharge rod. By incorporating built-in storage for insulating protective equipment for high-voltage operations, such as insulating gloves and discharge rods, operators do not need to carry these safety tools themselves, ensuring that no such tools are missed or misused, thus reducing operational risks.

[0021] Through the modular design of the enclosure, control panel, and storage space, combined with the coordinated layout of the caster wheels and built-in functional units, efficient integration and safe management of maintenance equipment are achieved.

[0022] The top cover 2 and the box body 1 are hinged together. Of course, for easy movement, there is also a lock between the two, so that the top cover 2 can be easily fixed to the box body 1.

[0023] The enclosure 1 is made of aviation aluminum, with an attractive appearance and an IP44 protection rating, providing excellent indoor waterproof and dustproof performance. Reinforcing blocks are provided on its top edge to enhance its strength.

[0024] The uninterruptible power supply has a rated capacity of 84Wh, the electric drum automatic cable reel has a cable length of 20m, allowing for long-distance operation, the stainless steel cable tray is wear-resistant, fire-retardant, 1.2mm thick, integrally molded, and more pressure-resistant, the insulating gloves can prevent workers from being injured by electric shock when operating high-voltage electrical equipment, the high-voltage insulating mat can be laid on the ground around the power distribution equipment to enhance insulation during operation and prevent high-voltage current from forming a circuit through the human body, causing electric shock injury or death, the discharge rod is used for discharging 10KV system power storage equipment after testing or shutdown, especially power cables and capacitors after testing, the residual charge is difficult to release, and the discharge rod needs to discharge to fully release the charge of these capacitive devices.

[0025] like Figure 3As shown, the operation panel is equipped with a double-pole circuit breaker 4 and a multi-output component. The multi-output component is connected to the double-pole circuit breaker 4 and the power cord output terminal of the automatic reel in the electric drum, respectively, for overall control. One of the outputs is connected to an uninterruptible power supply (UPS) and also has a smart meter that can display voltage and power in real time to prevent overload. The output component includes a residual current device (RCD) 5, a double-pole switch 6, and a five-hole socket 7 connected together, preventing violations during maintenance and ensuring safer use. One of the output components is connected to the UPS, which allows for maintenance work with low-power equipment at any time without being connected to mains power. The composite output component consisting of the RCD and the double-pole switch meets the industry requirement of "one machine, one switch, one protection". The integrated cabinet structure reduces the on-site equipment assembly process and eliminates the problem of equipment violations caused by missing tools or incorrect wiring.

[0026] like Figure 4 As shown, the inner side of the top cover is provided with a fixing cotton layer 8, and the fixing cotton layer 8 is provided with an adapter limiting groove. An adapter is installed in the adapter limiting groove, and the adapter connects to the interface of the automatic drum reel, thereby realizing a quick and safe connection. The linkage design of the automatic drum reel and the multi-output component, together with the adapter limiting groove and the interface positioning structure, significantly reduces the risk of cable tangling and the probability of interface misconnection; the fixing cotton layer on the inner side of the top cover uses a precision instrument to limit the area, avoiding equipment damage caused by transportation vibration.

[0027] The power cord input end of the automatic drum reel is equipped with an interface for connecting to the adapter, and the power cord inside the automatic drum reel has a positioning ball. The power cord input end of the automatic drum reel has an aviation interface for easy and quick connection, and the positioning ball on the power cord allows for adjustment of the output cord length. The power cord has a diameter of 3*2.5mm and can handle a power load of 5000W.

[0028] like Figure 4 As shown, the adapter includes a three-hole adapter 9, a U-shaped plug adapter 10, and a circuit breaker plug adapter 11, which can adapt to a variety of different connectors. After the power cord of the automatic drum reel is pulled out, the interface of the power cord can be connected to different adapters according to different adapter requirements, making it more convenient and faster to obtain power on site.

[0029] like Figure 3 As shown, the operation panel 3 is also equipped with indicator lights 12 and control buttons 13.

[0030] like Figure 4 As shown, the fixed cotton layer 8 is also provided with a lighting lamp limiting groove 14, an anemometer limiting groove 15, a warning sign limiting groove 16 and a lighting lamp charger limiting groove 17, which respectively limit the lighting lamp, anemometer, warning sign and lighting lamp charger.

[0031] like Figure 2 As shown, the side of the box 1 is provided with a box door 18, which is connected to the storage space.

[0032] The operation panel 3 is located on the upper part of the housing 1.

[0033] like Figure 2 and Figure 5 As shown, the bottom of the box 1 is equipped with casters 19 and a handle 20, and the side of the box 1 has a pull rod 21 and a pad 22. When moving the box 1, the casters 19 move on the ground, and the pull rod 21 pulls the box 1 to move it. During operation, the handle 20 is used to move the box 1, and the pad 22 supports it on the ground. The pad 22 prevents it from directly contacting the ground during use, thus providing protection and preventing dirt from getting in the way.

[0034] like Figure 2 As shown, the bottom of the housing 1 is provided with a grounding screw 23. The grounding screw is connected to the input ground wire and the internal metal frame, and is connected to the external grounding wire grounding nail through a wing nut, which facilitates installation and removal and can provide reliable grounding protection.

[0035] Through the modular design of the enclosure, control panel, and storage space, combined with the coordinated layout of the caster wheels and built-in functional units, efficient integration and safe management of maintenance equipment are achieved. The linkage design of the automatic cable reel and multi-output components, along with the adapter limit groove and interface positioning structure, significantly reduces the risk of cable tangling and the probability of incorrect interface connections. The fixing cotton layer on the inside of the top cover, with its zoned precision limiting instruments, prevents equipment damage caused by transportation vibrations. Meanwhile, the uninterruptible power supply allows for maintenance work using low-power equipment without connection to mains power. Furthermore, the composite output component consisting of a leakage current protection switch and a double-pole switch meets the industry requirement of "one machine, one switch, one protection," while the integrated enclosure structure reduces on-site equipment assembly, fundamentally eliminating equipment violations caused by missing tools or incorrect wiring.
