[0002] With the intelligent development of power distribution systems, more and more distribution boxes are integrating monitoring boxes to achieve real-time monitoring, data acquisition, and remote management of the operating status of power equipment. In practical applications, monitoring boxes are typically equipped with power supply modules, communication modules, and related monitoring circuits, and their operation requires continuous power and network connectivity.
[0003] However, in related technologies, monitoring boxes in power distribution systems typically employ a fixed installation structure or only have a simple sliding rail structure. When it is necessary to inspect, replace, or upgrade the modules inside the monitoring box, operators often need to disconnect the power cables and network connections before they can remove or pull out the monitoring box for operation. This not only increases the difficulty of maintenance but may also cause temporary system interruptions, data loss, or security risks. Utility Model Content

[0029] Please refer to them in order. Figs. 1 to 3 This application provides a drawer-type power distribution device 1, which includes at least a power distribution box 10, a monitoring module 20, and a cable follow-up assembly 30. The components are described below:
[0030] The distribution box 10 can be an energy storage cabinet, charging cabinet, communication cabinet, or other cabinet structure with power distribution function, used to accommodate internal functional components and forming an inner cavity 101 for installing the monitoring module 20. The front side (the side closest to the user interface) of the inner cavity 101 has an opening (not shown in the figure) communicating with the inner cavity 101, facilitating the monitoring module 20 to be pulled out and moved relative to the opening along the drawer direction for maintenance, repair, or external upgrades.
[0031] The monitoring module 20 can be an intelligent control unit for monitoring the operating status of the power distribution system. Specifically, it may include a data acquisition module, a communication module, a power management module, or a control logic module, and has the function of monitoring voltage, current, temperature, fault status, and other system operating parameters. Generally, the monitoring module 20 is installed in the inner cavity 101 of the distribution box 10 and forms a relatively movable connection with the distribution box 10 through a slide rail or guide structure, allowing it to move back and forth in the pull-out direction.
[0032] The cable follower assembly 30 can be a flexible guide structure composed of multiple connectable modular units, such as a tank chain, flexible drag chain, or chain conductor frame. It has an internal through-cavity for accommodating and protecting conventional cables 40 (e.g., power supply cables 401 and / or data transmission cables 402). The cable follower assembly 30 is disposed within the cavity of the distribution box 10, with one end connected to the monitoring module 20 and the other end fixed to the interior of the distribution box, allowing it to bend and extend as the monitoring module 20 is pulled or moved.
[0033] The power supply cable is used to guide the power supply voltage from the distribution box to the monitoring module 20; the data transmission cable is used to transmit monitoring data bidirectionally between the monitoring module and the remote control device or data platform in the system. Accordingly, since the cable follower component 30 guides the power supply cable and / or data transmission cable to move synchronously during the pulling process, it can effectively limit the bending radius and movement path of the cable, prevent the cable from being pulled, tangled or damaged, and ensure the continuity and reliability of the power supply and communication connection.
[0034] As can be seen, the drawer-type power distribution device of this application embodiment, by setting a pull-out monitoring module inside the power distribution box and cooperating with the cable follow-up component, allows the monitoring module to be pulled out without interrupting power or network connection. This facilitates the maintenance, upgrading, or external expansion of the internal monitoring module, avoiding system interruptions, data loss, or security risks caused by fixed or forcibly disconnected cables in the prior art. At the same time, the cable follow-up component can guide the cable to move synchronously during the pulling process, control the cable bending radius, and prevent pulling damage caused by repeated pulling, thereby improving the cable life and system operation stability. This significantly improves the maintenance efficiency and reliability of the power distribution system, and is particularly suitable for scenarios with high requirements for continuous operation, such as energy storage cabinets and charging cabinets.
[0035] It should be noted that the cable follower assembly 30 is pre-wound (coiled) in the inner cavity 101 to a length greater than or equal to the retractable length of the monitoring module 20. This ensures that the cable follower assembly 30 has sufficient extension stroke during the retraction of the monitoring module 20, and the conventional cables 40 (e.g., power supply cable 401 and / or data transmission cable 402) housed in the cable follower assembly 30 also have a corresponding wound length. Therefore, when the monitoring module 20 is fully pulled out in the retraction direction, the cable follower assembly 30 has a corresponding pullable length to maintain an effective extended state. The housed power supply cable and / or data transmission cable will not experience tension, tangling, or detachment due to insufficient stretching. This enables safe retraction, maintenance, or expansion operations of the monitoring module while maintaining uninterrupted power and network connectivity, improving system stability and maintenance convenience.
[0036] In an optional embodiment of this application, a linear guide structure 50 is further provided in the inner cavity 101 of the distribution box 10.
[0037] Specifically, the linear guide structure 50 is used to limit the pull-out path of the monitoring module 20, improving the stability and structural support effect during the pull-out process. The linear guide structure 50 can be a guide rail, slide rail, or roller track structure, and is roughly linearly aligned with the pull-out direction of the monitoring module 20.
[0038] The monitoring module 20 can be guided by a slider, pulley or guide rail assembly in conjunction with the linear guide structure 50, and move stably along the linear guide structure 50 during the pulling process, thereby realizing the linear guide pulling of the monitoring module 20 in the inner cavity of the distribution box, avoiding problems such as offset, shaking or jamming during the pulling process, and improving the accuracy and reliability of the pulling operation.
[0039] In an optional embodiment of this application, the cable follower assembly 30 includes a plurality of cable follower modules 301 that can be spliced together.
[0040] Specifically, each cable follower module 301 has a receiving cavity enclosed by a cable frame 302 to accommodate the cable. Each cable frame 302 is provided with a splicing part 303 for splicing and connecting with adjacent cable follower modules. Through the splicing part 303, multiple cable follower modules 301 can be spliced and connected end to end, so that each pair of adjacent cable follower modules 301 can rotate (forming a rotatable connection relationship at the splicing position), forming an overall bendable chain structure.
[0041] Each cable follower module 301 has a accommodating cavity that forms a flexible internal space after splicing, which is used to accommodate power supply cables and / or data transmission cables. As the monitoring module is pulled out, multiple cable follower modules 301 can move synchronously in the internal cavity 101. The flexibility of the flexible internal space accordingly prevents the cables from being damaged due to excessive stretching or bending.
[0042] In addition, multiple cable follower modules 301 are arranged linearly along the length of the linear guide structure 50 to cooperate with the linear guide trajectory of the monitoring module 20 during the pulling process, so as to ensure that the pulling length is within the allowable range while realizing the precise guidance and flexible movement of the cable follower components 301.
[0043] In an optional embodiment of this application, the cable follower module 301 arranged at the first position among the plurality of cable follower modules 301 is fixed to the side of the monitoring module 20 away from the opening, and the cable follower module 301 arranged at the last position among the plurality of cable follower modules 301 is fixed on the linear guide structure.
[0044] Specifically, as the monitoring module 20 moves along the pull-out direction, the cable follower component 30 achieves effective traction through the fixed connection at both ends, allowing the power supply cable and / or data transmission cable contained inside to be automatically extended or retracted throughout the entire pull-out stroke, thereby avoiding problems such as cable tangling, breakage or pull-out, and improving the stability and reliability of the structure.
[0045] In an optional embodiment of this application, the accommodating cavity of each cable follower module 301, or the flexible internal space formed by multiple cable follower modules 301, is used to accommodate the power supply cable 401 and / or the data transmission cable 402.
[0046] On one hand, one end of the power supply cable 401 is inserted into the accommodating cavity and electrically connected to the power supply interface of the monitoring module, and the other end is used to electrically connect to the power supply located in the inner cavity or the power supply located outside the power distribution device, so as to realize continuous power supply to the monitoring module.
[0047] On the other hand, the data transmission cable 402 includes a network cable. One end of the network cable passes through the accommodating cavity and is electrically connected to the network interface of the monitoring module, while the other end is used to electrically connect to a data transmission module disposed in the cavity or located externally.
[0048] In an optional embodiment of this application, a handle structure 201 is formed on the side of the monitoring module near the opening.
[0049] Specifically, the handle structure 201 is used for users to grip and pull the monitoring module 20 out of the inner cavity 101 of the distribution box 10, which facilitates the inspection, maintenance or functional upgrade of the monitoring module and improves the ease of use and human-computer interaction experience.
[0050] In optional embodiments of this application, the drawer-type power distribution device may further include other functional modules, such as a temperature and humidity sensing module for environmental monitoring, an audible and visual alarm module for fault alarm, a wireless communication module for remote communication, and a main control processing module for system control.
[0051] Specifically, these modules can be integrated into the monitoring module 20 or installed independently in the cavity of the distribution box 10 according to the actual power distribution system requirements. They are electrically connected to the monitoring module or external control system through the power supply cable 401 or the data transmission cable 402 to realize extended functions such as multi-functional integrated control, status feedback and remote communication, thereby further improving the intelligence level and flexibility of the power distribution device.
[0052] This application also provides an energy storage cabinet, including a cabinet body and a drawer-type power distribution device as described in the above embodiments, wherein the drawer-type power distribution device is disposed on the cabinet body.
[0053] The drawer-type power distribution device and energy storage cabinet of this application embodiment, by setting a pull-out monitoring module inside the power distribution box and cooperating with a cable follower component, allows the monitoring module to be pulled out without interrupting power or network connection. This facilitates the maintenance, upgrading, or external expansion of the internal monitoring module, avoiding system interruptions, data loss, or security risks caused by fixed or forcibly disconnected cables in the prior art. At the same time, the cable follower component can guide the cable to move synchronously during the pulling process, control the cable bending radius, and prevent pulling damage caused by repeated pulling, thereby improving the cable life and system stability. This significantly improves the maintenance efficiency and reliability of the power distribution system, and is particularly suitable for scenarios with high requirements for continuous operation, such as energy storage cabinets and charging cabinets.

For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
