[0044] Embodiment 1

[0045] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0046] Please refer to Figure 1-3 The embodiment of the present invention provides a comprehensive high-power natural moisture-removal maintenance power supply box, which is characterized by comprising a box body 1, a power supply and a top cover 2; wherein,

[0047] The top cover 2 is arranged on the top of the box body 1 to effectively protect and seal the inside of the box body 1;

[0048] The power supply is arranged inside the box 1, and serves as a source of stable and reliable energy supply for the entire maintenance power supply box;

[0049] The top cover 2 adopts a sloped structure design from top to bottom. This innovative design not only enhances the drainage performance of the top cover, but also optimizes its ability to resist wind and rain invasion; a guide groove 3 is provided on the side of the top cover 2 facing the interior of the box body 1. The guide groove 3 extends along the inclined direction of the top cover 2. Its design purpose is to efficiently guide and collect dew drops condensed from water vapor; a drain port is provided at the lower end of the guide groove 3; the drain port is located outside the box body 1, thereby ensuring that the dew drops accumulated in the guide groove 3 can be smoothly discharged to the outside of the box body 1.

[0050] It should be noted that the present invention has successfully realized the efficient collection and discharge of dew drops condensed from water vapor in the box by implementing the above-mentioned series of innovative designs, namely, designing the top cover 2 as a sloped structure, arranging the guide groove 3 on the inner side thereof, and finally opening the drain port 4 located outside the box body 1 at the end of the guide groove 3. This process not only effectively prevents the risk of electrical failure caused by the accumulation of dew drops in the box body 1, but also realizes the dehumidification and cooling of the box body in a natural way, thereby greatly ensuring the safe operation and stable performance of the maintenance power supply box under complex environmental conditions.

[0051] Please refer to Figure 1 In one implementation of the present embodiment, the box body 1 includes a bottom plate 11 and a side plate 12 located on the bottom plate 11 and enclosing a cavity with an upper end opening with the bottom plate 11; this design not only provides necessary protection space for internal components, but also optimizes the overall layout and function.

[0052] The bottom plate 11 and the side plate 12 are both designed with a double-layer structure, and the interlayer 13 is filled with heat insulation material.

[0053] It should be noted that the original intention of this design is to ensure that the internal temperature of the box 1 is maintained at a relatively constant state, thereby greatly reducing the temperature fluctuations in the box caused by changes in the external ambient temperature, and effectively alleviating the occurrence of condensation problems. At the same time, this design can also prevent the temperature in the box from being too high, providing the best operating environment for the secondary components and ensuring their stable and durable performance.

[0054] In addition, compared with the problems commonly found in the prior art power boxes, such as relatively simple structural design, easy deformation of the box body due to frequent switching operations during long-term use, and thus affecting the structural stability, the double-layer structure and the design scheme of adding fillers proposed in this embodiment show significant advantages. It not only significantly enhances the structural strength of the box body 1, but also greatly improves its sealing performance, so that the box body can achieve excellent sealing effect without the need for additional door lock accessories such as floor locks, windproof buckles, etc. This design not only simplifies the structure of the box body 1 and reduces production costs, but also significantly reduces the maintenance requirements caused by accessory failures, further improving the overall reliability and durability.

[0055] Please refer to Figure 1 In one implementation of the present embodiment, an opening is provided on one of the side panels 12, and a door 14 that can be rotated to open or close is provided at the opening.

[0056] It should be noted that the design of the box door 14 not only facilitates the user to access and maintain the interior of the box 1, but also ensures that the opening can be effectively closed when not in use, thereby maintaining the cleanliness and safety of the interior of the box 1. This detailed design reflects the careful consideration of the practicality and convenience of this embodiment, and provides users with a more flexible and efficient operating experience.

[0057] In one implementation of this embodiment, the bottom area of ​​the top cover 2 is larger than the top area of ​​the box body 1 .

[0058] It should be noted that this design not only increases the contact area between the top cover 2 and the box body 1, thereby improving the overall stability and sealing, but also helps to more effectively disperse the various external forces borne by the top cover 2, such as wind and rain, accidental impact, etc., and further protects the safety of the box body 1 and its internal components. In addition, this design may also help the rain or snow water accumulated on the top cover 2 to flow to the edge and be discharged more smoothly, reducing the risk of moisture infiltrating the box body, and creating a drier and more stable working environment inside the box body 1. This detailed design reflects the careful consideration of this embodiment in terms of structural design and functional optimization, and aims to provide users with a more reliable and durable product experience.

[0059] Please refer to Figure 1 In one implementation of the present embodiment, at least one of the side panels 12 is provided with a vent hole 15 , and a breathable and waterproof membrane is disposed in the vent hole 15 .

[0060] It should be noted that the use of the breathable and waterproof membrane is intended to achieve a delicate balance: on the one hand, it allows air to flow freely in and out of the box 1, which is essential for maintaining the freshness of the air in the box 1, regulating the temperature, and preventing internal components from overheating; on the other hand, this film can effectively block the entry of moisture, dust and other potential contaminants, thereby ensuring the cleanliness and dryness of the internal environment of the box 1.

[0061] This detailed design not only reflects the careful consideration of this embodiment in ensuring the stability of the internal environment of the box 1, but also further enhances the protective performance of the box 1, providing users with a safer and more reliable use experience. By cleverly combining the vent hole 15 with the breathable and waterproof membrane, this embodiment successfully solves the contradiction between ventilation and protection in traditional power boxes, setting a new benchmark for related industries.

[0062] Please refer to Figure 2 In one implementation of the present embodiment, a plurality of guide grooves 3 are provided on one side of the top cover 2 facing the interior of the power box.

[0063] The plurality of guide grooves 3 are distributed at equal intervals.

[0064] It should be noted that this layout is designed to maximize the use of the top cover surface and ensure that the dew condensed from the top cover can flow into the guide groove quickly and evenly.

[0065] The design of the equally spaced guide grooves 3 not only improves the efficiency of dew collection, but also ensures the stability of the dew during the flow process, reducing the problem of liquid accumulation caused by poor flow. This detailed design reflects the innovation and practicality of this embodiment in solving the condensation problem, and provides users with a more efficient and reliable power box experience. At the same time, this design also further enhances the protection performance of the power box and extends its service life.

[0066] In one implementation of this embodiment, the slope θ of the top cover 2 is determined by the following formula:

[0067] θ = arctan(h / l);

[0068] Wherein, h is the height difference of the top cover 2 relative to the horizontal plane, and l is the horizontal distance of the top cover 2 on the horizontal plane.

[0069] It should be noted that this design not only reflects the professionalism of this embodiment in solving the condensation problem, but also demonstrates its rigor and precision in structural design. The slope of the top cover is determined by a scientific calculation method to ensure that dewdrops can flow into the guide groove quickly and smoothly, thereby effectively reducing the potential threat of condensation to the internal components of the power box. This detailed design undoubtedly provides users with a safer and more reliable power box experience.

[0070] In one implementation of this embodiment, the total capacity of the power supply is 630A.

[0071] It should be noted that with the continuous standardization of power grid maintenance work, the demand for 380V AC power supply is also increasing. However, the total capacity of the maintenance power supply boxes commonly used in substations is mostly between 100A and 150A, which obviously cannot meet the operation needs of large machinery. In order to solve this problem, on-site staff often have to take power directly from the 380V AC feeder panel, which not only requires laying a long temporary power cable on the maintenance walkway in the substation, increasing the complexity of the operation, but more importantly, this practice has serious risks of electric shock and is an irregular use of electricity.

[0072] Therefore, this embodiment specially designs a 630A large-capacity and high-power power supply to meet the power demand of large machinery during operation. This design not only ensures the stability and reliability of the power supply of large machinery, but also realizes the rapid access of emergency power supply, providing a strong guarantee for the reliable supply of electricity. At the same time, this design also effectively avoids the safety hazards caused by directly taking power from the feeder panel, and improves the standardization and safety of electricity use.

[0073] In one implementation of this embodiment, the output end of the power supply is provided with a dustproof and waterproof aviation socket.

[0074] It should be noted that this design not only improves the protection performance of the socket, but also forms a sharp contrast with the existing power box socket in terms of functionality.

[0075] It should be pointed out that the power box sockets commonly used in the current market are mostly traditional three-hole designs. This design is incapable of coping with the complex and changeable power grid environment, especially when matching with the emergency power generation vehicle quick access device. There are obvious compatibility issues, which seriously affect the reliability and stability of the power supply of the power grid.

[0076] In order to solve this problem, this embodiment specially adopts a dustproof and waterproof aviation socket, which not only has excellent protection performance and can effectively resist the erosion of the internal circuit of the socket by harsh environment, but also innovates in the design of the socket and sets four cable access sockets. These sockets perfectly match the output of the emergency generator truck, realizing fast and stable power access.

[0077] This design not only greatly improves the applicability and application scope of the power box, making it widely used in substations of various voltage levels, but also shows significant advantages in solving key problems such as insufficient power supply, moisture in the box, and inability to quickly access emergency power supply during production. Therefore, the dustproof and waterproof aviation socket designed in this embodiment has broad application prospects and important practical value.

[0078] Although the terms such as box, top cover, ramp, etc. are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0079] An embodiment of the present invention provides a comprehensive high-power natural moisture-removal maintenance power box, which designs the top cover as a sloped structure from top to bottom, and sets a guide groove on the side of the top cover facing the inside of the box body, and then opens a drain port located outside the box body at the bottom of the guide groove. After the water vapor in the box forms condensation on the top cover, it can flow along the guide groove to the drain port, thereby discharging the condensation outside the box body, achieving the effect of natural moisture-removal and natural cooling, and ensuring the safe operation of the maintenance power box.

[0080] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
