Description

Technical Field

[0001] This application belongs to the field of power equipment technology, specifically relating to a power distribution cabinet energy storage component and a power distribution cabinet. Background Technology

[0002] As a key device for power distribution, control, and protection, the distribution cabinet integrates electrical components such as circuit breakers, contactors, protective relays, and control circuit boards. Its normal operation depends on external power grid supply. When a power grid fault, line interruption, or internal component failure occurs, the distribution cabinet loses power input, resulting in the loss of its original functions. At this time, its critical loads (such as protective relays and control circuit boards) face severe challenges: the protective relays, after losing power, cannot monitor line parameters or isolate faults, potentially leading to the escalation of electrical accidents; the control circuit boards stop working, paralyzing intelligent functions such as remote communication, status monitoring, and automatic switching, severely restricting the recovery speed and operational reliability of the power supply system.

[0003] To address power supply issues during power outages, existing technologies commonly employ built-in backup batteries as reserve energy. When a main power interruption is detected, a switching circuit connects the backup battery to the system, providing emergency power to the aforementioned critical electrical components to maintain their basic functions for a short period.

[0004] The inventors discovered that the power supply time of backup batteries is limited by their rated capacity. Once the power is depleted, the system will fail again, resulting in insufficient reliability in long-term use scenarios. Secondly, batteries in idle states suffer from lifespan degradation, performance greatly affected by ambient temperature, and the need for regular maintenance and replacement, leading to unstable long-term power supply and high maintenance costs. Utility Model Content

[0005] This application provides a power storage component and a power distribution cabinet for a power distribution cabinet, aiming to overcome the technical defects of fixed-capacity power storage having limited power supply time during power outages and relying on regular maintenance, thereby improving the reliability of its power supply.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A power storage component for a power distribution cabinet is provided, comprising: The mounting box is used to fix it on the top of the power distribution cabinet, and guide holes communicating with the inside of the mounting box are opened on both opposite sides of the mounting box. Two positioning plates are slidably inserted into the two guide holes, respectively; each positioning plate has a solar panel on its upper side, and the solar panel is used to electrically connect to a critical load to generate electricity and supply power to the critical load when it extends out of the mounting box; and A synchronous drive component, which is connected to the two positioning plates, is used to drive the two positioning plates to move in opposite directions so that both solar panels extend outside the mounting box.

[0007] In one possible implementation, the synchronization drive component includes: Two transmission components are arranged side-by-side within the mounting box along the axial direction of the guide hole. Each transmission component is slidably connected to the mounting box along the axial direction of the guide hole, and each of the two transmission components is respectively connected to two positioning plates, so that the transmission components and the corresponding positioning plates move synchronously along the axial direction of the guide hole; and A double-ended screw is rotatably disposed inside the mounting box, positioned between the positioning plate and the top surface of the mounting box, and its axial direction and rotational axis are both parallel to the axial direction of the guide hole; the double-ended screw has two threaded portions arranged along its axial direction with opposite thread directions, and the two threaded portions are respectively threadedly connected to the two transmission components, so that when the double-ended screw rotates, the two transmission components move towards each other or away from each other; The double-ended screw drive is connected to a rotary motor for driving its rotation.

[0008] In one possible implementation, the rotary motor is fixedly mounted on the inner top surface of the mounting box, and its power output axis is parallel to the axis of the double-ended screw. The double-ended screw has a driven gear coaxially connected to it, and the power output shaft of the rotating motor has a driving gear coaxially connected to the driven gear.

[0009] In one possible implementation, the transmission member has a reserved hole suitable for the double-ended screw to pass through, and a transmission nut fixedly connected thereto and coaxially communicating with the reserved hole, and the transmission nut is threadedly connected to the corresponding threaded portion.

[0010] In one possible implementation, the mounting box includes: The enclosure, used for fixed installation on the top of the distribution cabinet, has a hollow interior and an open top; and A lid is detachably mounted on the upper side of the box body and is adapted to close the opening of the box body; The two guide holes are respectively opened on opposite sides of the housing; the transmission component, the double-headed screw and the rotating motor are all mounted on the housing cover.

[0011] In one possible implementation, the inner side of the box body is provided with a groove, and the lower side of the box cover has a protruding ridge suitable for embedding into the interior of the box body; The convex ridge has a snap-fit ​​portion; when the lid is aligned with the upper side of the box body, the snap-fit ​​portion is embedded in the groove; and the outer side of the box body has an unloading hole communicating with the groove.

[0012] In one possible implementation, both positioning plates have slots on their upper sides, and both transmission components have connectors. When the lid is aligned with the upper side of the box body, the two connectors are inserted into the two sockets respectively, so that when the transmission component moves axially along the guide hole, the positioning plate moves synchronously.

[0013] In one possible implementation, the mounting box further includes: Both sealing caps are hinged to the outside of the mounting box and are respectively located on the sides facing the two guide holes; and Two sets of magnetic components are fixedly installed on the inner sides of the two sealing covers to generate a magnetic attraction with the outer side of the power distribution cabinet.

[0014] In one possible implementation, a recessed groove is provided on the upper side of the positioning plate; The solar panel is embedded in the recessed groove so that the upper side of the solar panel is aligned with the upper side of the positioning plate, or the upper side of the solar panel is below the upper side of the positioning plate.

[0015] In this embodiment, by setting up an installation box, two positioning plates, and solar panels respectively mounted on the positioning plates, and using a synchronous drive component to drive the two positioning plates to move in opposite directions, the solar panels can extend from inside the installation box to the outside. When the power distribution cabinet is powered normally, the solar panels can be stored in the installation box for protection; when the power distribution cabinet is powered off, the solar panels can quickly extend into the external sunlight environment to directly generate electricity using solar energy.

[0016] In the above process, solar energy, as a renewable external energy source, does not rely on pre-stored electricity, thus fundamentally overcoming the problem of limited power supply time caused by the fixed capacity of traditional backup batteries. The extended solar panels can continuously generate electricity under sunlight, providing sustained power to critical loads within the distribution cabinet (such as protective relays and control circuit boards). This not only ensures that the protective relays can continue to perform line monitoring and fault isolation functions after a power outage, preventing the escalation of electrical accidents, but also ensures that the control circuit boards maintain their intelligent functions such as remote communication and status monitoring, significantly improving the power supply system's recovery capability and operational reliability under fault conditions.

[0017] The energy storage component for the distribution cabinet provided in this embodiment, compared with the prior art, converts the stored energy from fixed chemical energy (batteries) into actively obtainable solar energy, and uses a mechanical structure to realize the on-demand extension and retraction of the energy carrier, realizing a shift in the energy supply mode from "consuming existing resources" to "creating incremental resources." This not only solves the core defect of limited power supply time in traditional solutions and significantly improves power supply reliability, but also eliminates the corresponding maintenance costs and lifespan concerns by reducing reliance on batteries, giving the distribution cabinet better self-sustaining operation capability and economy in the event of a power outage.

[0018] The technical solution adopted in this application also provides a power distribution cabinet, including the energy storage component for power distribution cabinets proposed in any of the preceding claims.

[0019] The beneficial effects of the power distribution cabinet provided in this embodiment are the same as those of the aforementioned power distribution cabinet energy storage components, and will not be repeated here. Attached Figure Description

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0023] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 14 The energy storage component for the distribution cabinet provided in this application will now be described. The energy storage component proposed in this application includes a mounting box 1, two positioning plates 2, and a synchronous drive component 3.

[0027] Mounting box 1 is used to fix it on the top of the distribution cabinet; guide holes 111 are opened on both sides of the horizontal direction of the mounting box 1, and the guide holes 111 are connected to the inside of the mounting box 1.

[0028] Two positioning plates 2 are slidably inserted into two guide holes 111 respectively; each positioning plate 2 has a solar panel 10 on its upper side, which is electrically connected to the critical load in the distribution cabinet. When the positioning plate 2 drives the solar panel 10 out of the mounting box 1, the solar panel 10 can generate electricity and supply power to the critical load.

[0029] The synchronous drive component 3 is connected to the two positioning plates 2 in a transmission manner; this component is used to drive the two positioning plates 2 to move in opposite directions along the guide hole 111, thereby causing the two solar panels 10 to extend out of the mounting box 1. Alternatively, it can drive the two positioning plates 2 to move in opposite directions along the guide hole 111, thereby causing the two solar panels 10 to retract into the mounting box 1.

[0030] This embodiment of the application provides a housing and guiding structure through the mounting box 1, and uses a synchronous drive component 3 to control the synchronous back-to-back movement of two positioning plates 2 to achieve the extension and retraction of the solar panel 10. This design allows the solar panel 10 to be stored inside the mounting box 1 when the power distribution cabinet is powered normally, avoiding the influence of the external environment; when the power distribution cabinet is powered off, the solar panel 10 can quickly extend to the outside, using solar energy to continuously generate electricity and provide power support for critical loads.

[0031] In the above process, solar energy, as a renewable external energy source, does not rely on pre-stored electricity, fundamentally overcoming the problem of limited power supply time of traditional fixed-capacity batteries. The extended solar panels 10 can continuously generate electricity under sunlight conditions, ensuring that critical loads such as protection relays and control circuit boards can continue to operate normally after a power outage; this not only maintains functions such as line monitoring, fault isolation, remote communication, and status monitoring, but also significantly improves the recovery capability and overall reliability of the power supply system under fault conditions.

[0032] Compared to existing technologies, this embodiment transforms energy storage from relying on fixed chemical energy (batteries) to actively obtainable solar energy. Through a mechanical structure, the energy carrier can be extended and retracted on demand, upgrading the energy supply mode from "consuming existing resources" to "creating new resources." This solution not only effectively extends emergency power supply time but also reduces reliance on batteries, avoiding problems such as battery lifespan degradation, performance fluctuations, and regular maintenance. It also improves the self-sustaining operation capability and economy of the distribution cabinet under power outage conditions.

[0033] In some embodiments, such as Figures 4 to 7 As shown, the synchronous drive component 3 includes two transmission components 31 and a double-ended screw 32.

[0034] Two transmission components 31 are arranged side by side in the mounting box 1 along the axial direction of the guide hole 111. Each transmission component 31 is slidably connected to the mounting box 1 along the axial direction of the guide hole 111. The two transmission components 31 are respectively connected to the two positioning plates 2 to realize the axial synchronous movement of the transmission component 31 and the corresponding positioning plate 2.

[0035] The double-ended screw 32 is rotatably mounted inside the mounting box 1, located between the positioning plate 2 and the top surface of the mounting box 1; the axial direction and rotational direction of the double-ended screw 32 are both parallel to the axial direction of the guide hole 111; the double-ended screw 32 has two threaded portions arranged axially and with opposite thread directions, and the two threaded portions are respectively threadedly connected to two transmission components 31, so that when the double-ended screw 32 rotates, the two transmission components 31 can move towards or away from each other.

[0036] The double-ended screw 32 is connected to a rotary motor 4, which drives the double-ended screw 32 to rotate.

[0037] This structure achieves symmetrical movement of two transmission components 31 through a single drive source, ensuring that the positioning plates 2 on both sides extend or retract synchronously. The structure is compact and easy to control.

[0038] In some embodiments, such as Figure 7 and Figure 11 As shown, the rotating motor 4 is fixedly mounted on the inner top surface of the mounting box 1, and its power output axis is parallel to the axis of the double-headed screw 32.

[0039] A driven gear 321 is coaxially connected to the double-ended screw 32; a driving gear 41 is coaxially connected to the power output shaft of the rotating motor 4, and the driving gear 41 and the driven gear 321 mesh with each other.

[0040] This gear transmission structure effectively transmits the rotation of the rotating motor 4 to the double-headed screw 32, achieving smooth and reliable power transmission.

[0041] In some embodiments, such as Figure 5 and Figure 12As shown, a reserved hole 311 is provided on the transmission component 31, which is suitable for the double-ended screw 32 to pass through.

[0042] A transmission nut 312 is fixedly connected to the transmission component 31, and the transmission nut 312 is coaxially connected to the reserved hole 311; the transmission nut 312 is threadedly engaged with the corresponding threaded part on the double-ended screw 32.

[0043] This design converts the rotational motion of the double-ended screw 32 into the linear motion of the transmission component 31, resulting in stable transmission and high precision.

[0044] In some embodiments, such as Figure 4 and Figure 9 As shown, the installation box 1 includes a box body 11 and a box cover 12.

[0045] The enclosure 11 is fixedly installed on the top of the distribution cabinet. Its structure is hollow inside and open to the top. Two guide holes 111 are respectively opened on opposite sides of the enclosure 11.

[0046] The cover 12 is detachably mounted on the upper side of the box body 11 to close the opening of the box body 11; the transmission component 31, the double-headed screw 32 and the rotating motor 4 are all mounted on the cover 12.

[0047] By adopting the above technical solution, the modular structure facilitates the installation and maintenance of internal components and improves assembly efficiency.

[0048] In some embodiments, such as Figure 13 and Figure 14 As shown, a groove 112 is provided on the inner side of the box body 11; a protruding rib 121 is provided on the lower side of the box cover 12, and the protruding rib 121 is suitable for being embedded inside the box body 11.

[0049] A snap-fit ​​part 122 is provided on the protruding ridge 121; when the lid 12 is aligned with the upper surface of the box body 11, the snap-fit ​​part 122 is embedded in the groove 112 to realize the positioning and fixing of the lid 12 and the box body 11.

[0050] The outer side of the housing 11 is provided with an unloading hole 113, which communicates with the groove 112; the hole can be used to insert a tool to open the snap-fit ​​part 122, so as to facilitate the disassembly of the housing cover 12.

[0051] By adopting the above technical solution, the snap-fit ​​structure enables the quick installation and removal of the cover 12, while ensuring the stability of the structural connection.

[0052] In some embodiments, such as Figure 5 , Figure 8 and Figure 12 As shown, both positioning plates 2 have slots 21 on their upper sides; both transmission components 31 have connectors 313.

[0053] When the cover 12 is aligned with the upper surface of the box body 11, the two connectors 313 are inserted into the two sockets 21 respectively; when the transmission component 31 moves axially along the guide hole 111, the positioning plate 2 moves synchronously through the cooperation of the connectors 313 and the sockets 21.

[0054] In some embodiments, such as Figure 9 and Figure 10 As shown, the mounting box 1 also includes two sealing covers 5 and two sets of magnetic components 6.

[0055] Two sealing caps 5 are hinged to the outside of the mounting box 1, and each sealing cap 5 corresponds to the side where a guide hole 111 is located.

[0056] Two sets of magnetic components 6 are fixedly installed on the inner sides of the two sealing covers 5, which are used to generate a magnetic attraction with the outer side of the distribution cabinet.

[0057] After the solar panel 10 is retracted, the structure can seal the area of ​​the guide hole 111 through the sealing cover 5. The magnetic design makes it easy to fix and open the sealing cover 5, which plays a role in dust prevention, waterproofing and protection.

[0058] In some embodiments, such as Figure 8 As shown, a recessed groove 22 is provided on the upper side of the positioning plate 2.

[0059] The solar panel 10 is embedded in the recessed groove 22; after installation, the upper side of the solar panel 10 is aligned with the upper side of the positioning plate 2, or slightly lower than the upper surface of the positioning plate 2.

[0060] The sunken installation structure can effectively protect the solar panel 10, preventing it from being bumped or scratched during movement and storage, thus extending its service life. At the same time, since the solar panel 10 is embedded under the upper surface of the positioning plate 2, the positioning plate 2 can effectively seal the guide hole 111 to prevent moisture and dust from entering the interior of the housing 11.

[0061] Based on the same inventive concept, embodiments of this application also provide a power distribution cabinet, including the energy storage component for power distribution cabinets proposed in any of the preceding claims.

[0062] The beneficial effects of the power distribution cabinet provided in this embodiment are the same as those of the aforementioned power distribution cabinet energy storage components, and will not be repeated here.

[0063] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
