[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] The following describes in detail the overall structure, working principle, and technical effects of the power adapter box provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0026] Please refer to Figures 1-3 This embodiment provides a power adapter box 100, whose core function is to realize standardized access, convergence, redistribution, and safety monitoring of electrical energy. The overall structural design of the power adapter box 100 fully considers the stringent requirements of military environments, emphasizing reliability, airtightness, portability, and ease of use.

[0027] The power adapter box 100 includes a housing 10, a door 20, an input interface 30, an output interface 50, a busbar 40, and a status monitoring unit 60. The housing 10 is welded from steel plates, and all seams of the housing 10 are fully welded to ensure a tight seal. The door 20 is connected to the housing 10 via hinges to open or close the housing 10. The input interface 30 and output interface 50 are respectively located on both sides of the housing 10. The busbar 40 is fixed inside the housing 10. The input interface 30 is connected in parallel to the busbar 40 via a wire 41. The output interface 50 is led out from the busbar 40 via a wire 41. The status monitoring unit 60 is connected to the wire 41 of the input interface 30 and is used to detect the electrical parameters of the input power supply.

[0028] By setting up a three-level electrical structure of input interface 30-bus 40-output interface 50, non-standard input power supplies of different specifications can be combined and redistributed into standardized outputs, thereby achieving rapid and universal connection between mobile power stations and electrical equipment, solving the fundamental problems of physical interface mismatch and electrical parameter incompatibility. By setting up a status monitoring unit 60 connected to the input circuit, the voltage, phase, and other key parameters of the input power supply can be monitored and displayed in real time, allowing for rapid identification of power supply anomalies (such as phase reversal, undervoltage, and overvoltage) before power supply, avoiding equipment damage and operational delays caused by power supply mismatch, and significantly improving the safety and reliability of power supply support. By integrating the enclosure 10, door 20, interfaces, bus 40, and monitoring unit into a single device, a standardized interface platform independent of existing power stations and equipment can be provided, transforming complex field cable fabrication work into a simple "plug-and-play" operation, reducing power supply preparation time in field conditions from hours to minutes, greatly improving the timeliness of operational response and the agility of equipment support.

[0029] The door 20 is connected to the housing 10 via a hinge to open or close the housing 10, which enables stable opening and closing of the door 20. This allows operators to quickly inspect and maintain the connection status of the busbar 40 and wires 41 inside the housing 10.

[0030] Specifically, the enclosure door 20 includes a front door 21 and a rear door 22. The front door 21 and rear door 22 are respectively connected to the enclosure door 20 via hinges. The front door 21 and rear door 22 are respectively located on the front and rear sides of the enclosure 10. In this embodiment, the input interface 30 and output interface 50 are respectively located on the left and right sides of the enclosure 10. By setting up a double-door independent structure with the front door 21 and rear door 22 located on the front and rear sides of the enclosure 10, separate inspection and operation of the front and rear areas can be achieved, improving the convenience of equipment maintenance and operational safety.

[0031] In this embodiment, a door lock 26 is provided between the door 20 and the enclosure 10. By providing the door lock 26 between the door 20 and the enclosure 10, the door 20 can be securely locked after being closed, thereby preventing the enclosure 10 from being accidentally opened during transportation or in harsh environments, and ensuring the safety and operational reliability of the internal electrical components.

[0032] Furthermore, input interface 30 consists of multiple standardized input connectors, and output interface 50 consists of multiple standardized output connectors. The input and output connectors may be of the same or different models. By using standardized input and output connectors, complete standardization of the interfaces can be achieved, ensuring mechanical interchangeability and electrical compatibility between all mating cable plugs and sockets, thereby resolving the problem of physical incompatibility between interfaces.

[0033] In this embodiment, the input and output connectors are of the same model. By setting a symmetrical structure where the input and output connectors are of the same model, the electrical and mechanical characteristics of both the input and output ends can be kept consistent. This simplifies spare parts inventory, and all interfaces can be maintained using spare parts of the same specification, significantly reducing the complexity of logistical support.

[0034] Of course, in another embodiment, the input and output connectors can be configured with different models. By setting different adapter structures for the input and output connectors, the interface types can be flexibly configured according to actual needs, thereby adapting to the special requirements of the interface specifications of the devices in different situations, and improving the applicability and deployment flexibility of the equipment.

[0035] Furthermore, recesses 25 are provided on both sides of the housing 10. The input and output connectors are respectively located within the recesses 25 on both sides of the housing 10. It can be understood that by setting the input and output connectors to a structure that is recessed relative to the sides of the housing 10, it is possible to effectively prevent the input and output connectors from being impacted or scratched during the handling of the housing 10, avoid connector interface failure due to mechanical damage, and significantly improve the durability and reliability of the equipment.

[0036] Specifically, in this embodiment, the number of input interfaces 30 is set to three. The number of output interfaces 50 is set to three. The three input interfaces 30 are connected in parallel to the busbar 40 via wires 41, and the three output interfaces 50 are led out from the busbar 40 via wires 41. Each input interface 30 can meet 60kW input, and each output interface 50 can meet 60kW output. The three power supplies input from the left are connected to the busbar 40 via internal wires 41. The current carrying capacity of the busbar 40 can meet the superimposed power of the three power supplies connected at the same time, up to a maximum of 180kW. Then, the power is split into three outputs from the busbar 40 and connected to the output interfaces 50 on the right via internal wires 41.

[0037] In this embodiment, a glass window 23 is provided on the door 20 to facilitate observation of the internal structure of the enclosure 10. By providing the glass window 23, the internal state can be observed directly without opening the door 20, improving the portability of the equipment.

[0038] Furthermore, the status monitoring unit 60 includes a phase sequence indicator 61 and a digital voltage display 62. The phase sequence indicator 61 and the digital voltage display 62 are installed inside the enclosure door 20 and connected to the wire 41 of the input interface 30. The status of the phase sequence indicator 61 and the digital voltage display 62 can be observed through the glass window 23. By setting a direct connection structure between the status monitoring unit 60 and the wire 41 of the input interface 30, the quality of the input power supply can be monitored at the source, thereby detecting power abnormalities before power distribution and preventing problematic power from being delivered to electrical equipment, ensuring power supply safety from the source. The integrated installation structure of the phase sequence indicator 61 and the digital voltage display 62 allows two key monitoring functions to be centrally located inside the enclosure door 20, enabling simultaneous observation of phase sequence and voltage parameters through the glass window 23, improving the efficiency and convenience of status monitoring.

[0039] Specifically, in this embodiment, the phase sequence indicator 61 and the voltage digital display 62 are both installed inside the enclosure 10 at positions corresponding to the glass window 23, and the phase sequence indicator 61 and the voltage digital display 62 are positioned close to the enclosure door 20 to facilitate observation of the phase sequence and voltage parameters.

[0040] In this embodiment, the busbar 40 is a three-phase four-wire busbar 40, including four busbars: U, V, W, and N. The busbar 40 is fixed to the bottom wall of the enclosure 10 by bolts, and an insulating plate is provided between the busbar 40 and the enclosure 10. It can be understood that by setting the three-phase four-wire busbar 40 structure with four busbars (U, V, W, N), all phase wires and the neutral wire of three-phase AC power can be completely transmitted, thereby meeting the diverse power supply needs of various three-phase and single-phase electrical equipment and realizing complete power distribution functions. By setting the insulating plate isolation structure between the busbar 40 and the bottom wall of the enclosure 10, the busbars and the enclosure 10 can be electrically isolated, thereby preventing short-circuit accidents and ensuring the electrical safety and reliability of the system operation.

[0041] To improve the sealing and waterproofing of the enclosure 10, a water guide groove (not shown) and a sealing strip 24 are provided at the contact point between the enclosure 10 and the door 20. Specifically, in this embodiment, the door 20 is a square door, and the water guide groove and sealing strip 24 are located on the four sides of the door 20. When the door 20 is closed, the sealing strip 24 seals the gap between the door 20 and the enclosure 10. The water guide groove is used to collect and guide any liquid that may be mixed into the enclosure 10, and discharge it along a predetermined path. For example, in this embodiment, the water guide groove is used to guide the liquid to flow downwards and discharge it from both sides of the bottom of the enclosure 10.

[0042] Specifically, a water guide channel is installed on the door frame of the enclosure 10, and a sealing strip 24 is installed on the door 20. The cross-section of the water guide channel can be U-shaped or V-shaped. By combining the water guide channel on the door frame with the sealing strip 24 on the door 20, a dual waterproof mechanism of a physical barrier and a drainage barrier can be formed, which can greatly improve the overall protection level of the enclosure 10 and effectively resist the intrusion of rainwater, splashes, and other liquids.

[0043] Furthermore, multiple shock absorbers 11 are installed at the bottom of the enclosure 10. By setting up shock absorbers 11, vibration and impact energy generated during transportation and operation can be absorbed, thereby protecting the electrical connection points of the busbar 40 inside the enclosure 10 from loosening due to continuous vibration, avoiding the risk of increased contact resistance, overheating or even power failure, and ensuring the long-term reliability of the power supply connection.

[0044] Specifically, in this embodiment, the shock absorber 11 is a rubber shock absorber 11. The shock absorber 11 is installed at the bottom of the housing 10 and is used to contact the ground or tabletop. It absorbs and dissipates energy through elastic deformation, isolating vibration and impact. In this embodiment, the shock absorber 11 is installed at the four corners of the bottom of the housing 10. The shock absorber 11 is cylindrical in shape, thus stably supporting the housing 10. In this embodiment, the shock absorber 11 can be fixedly connected to the bottom plate of the housing 10 with bolts and can withstand forces in all directions.

[0045] Of course, in other embodiments, the shock absorber 11 may also adopt other structures, such as spring shock absorber 11, etc. The present invention does not limit the specific type of shock absorber 11.

[0046] Furthermore, a handle 12 is provided on the top of the housing 10. By providing the handle 12, operators can easily move the power adapter box 100, improving the portability of the equipment during field deployment and relocation.

[0047] Specifically, the handle 12 is rotatably connected to the top of the housing 10 via a hinge. The top of the housing 10 is also provided with a clearance groove for storing the handle 12. By setting the handle 12 rotation structure and clearance groove, the handle 12 can be flexibly switched between a vertical carrying position and a horizontal storage position.

[0048] The beneficial effects of the power adapter box 100 provided in this embodiment of the present invention include: The power adapter box 100 provided by this utility model includes a box body 10, a door 20, an input interface 30, an output interface 50, a busbar 40, and a status monitoring unit 60. The door 20 is connected to the box body 10 via hinges to open or close the box body 10. The input interface 30 and the output interface 50 are respectively located on both sides of the box body 10. The busbar 40 is fixed inside the box body 10. The input interface 30 is connected in parallel to the busbar 40 via a wire 41. The output interface 50 is led out from the busbar 40 via a wire 41. The status monitoring unit 60 is connected to the wire 41 of the input interface 30 and is used to detect the electrical parameters of the input power supply. Through the three-level architecture design of "input interface 30-busbar 40-output interface 50", the working principle of power convergence and redistribution is adopted, which solves the interface compatibility problem between mobile power stations of different specifications and electrical equipment, and realizes the technical effect of converting multiple non-standard inputs into a unified standard output. Compared to existing solutions that require temporary adapter cables, this invention achieves plug-and-play functionality, reducing equipment power preparation time from hours to minutes, significantly improving the timeliness of combat response. This invention also solves the problem of incompatibility between military power interfaces, enabling rapid connection and secure power supply, thus enhancing operational support efficiency.
