Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power supply control, and in particular to a distributed management device for energy storage power supply. Background Art

[0002] The distributed management device of energy storage power supply is a technical system used to monitor, control and optimize the performance of distributed energy storage systems (such as batteries, flywheels, supercapacitors, etc.). Its main function is to ensure the efficient operation of energy storage equipment, improve the stability and reliability of the power system, and support the integration and utilization of renewable energy. In order to ensure the reliability and stability of the system, the distributed management device of energy storage power supply is mostly equipped with redundant power supply. Even if the main power supply fails or is interrupted, the backup power supply can take over immediately to ensure the continuous operation of the system. This setting can prevent single point failures and enhance the system's risk resistance, especially in mission-critical applications such as medical equipment, data centers and communication base stations. The continuity of power supply is crucial, and redundant power supplies provide additional protection to ensure that the system can continue to operate stably under any circumstances.

[0003] In the prior art, the redundant power switching structure of the energy storage power distributed management device is mostly a pure electric switching mechanism, and the power of the switching mechanism is taken from the power supply originally connected to the energy storage power distributed management device. When the working power supply is accidentally damaged and cannot supply power, the switching mechanism for switching the redundant power supply cannot continue to work and cannot perform the switching operation to the redundant power supply. This design lacks independent power supply support, resulting in the inability to switch to the backup power supply in time at critical moments, increasing the risk of system downtime, and reducing the reliability and availability of the system. In addition, the difficulty of maintenance after a failure increases, and the response time is delayed, further affecting the overall stability of the system. Summary of the invention

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-13 A distributed management device for energy storage power supply includes an installation box 1 and a vertical edge 4. Two groups of installation boxes 1 are provided. The vertical edge 4 is vertically fixed at the edge position of the side of the installation box 1. A fixing bolt 2 is screwed into the vertical edges 4 on the sides of the two groups of installation boxes 1. A bottom sealing plate 5 is fixed at the bottom of the inner cavity of the installation box 1. A top sealing plate 3 is provided above the bottom sealing plate 5 in the inner cavity of the installation box 1. The bottom sealing plate 5 and the top sealing plate 3 separate the inner cavity of the installation box 1. The appearance of the installation box 1 is a half rectangular box. The two installation boxes 1 are combined into a complete rectangular box through the vertical edge 4 for installing the entire distributed management device.

[0036] A common box 6 is fixedly provided at the top center position of the top sealing plate 3, and a distributed controller body 16 is fixedly provided inside the common box 6. The top of the common box 6 is in an open state, exposing the top of the distributed controller body 16 to facilitate the connection of the distributed controller body 16 with the external energy storage power supply to be controlled.

[0037] The main structure of the distributed controller body 16 is a technical system that integrates a monitoring system, a control system, a communication system, a power electronic device and a software platform. Its main functions include real-time data acquisition, status monitoring, charge and discharge control, balance management, optimization scheduling, data transmission and remote control. The main structure of the distributed controller body 16 is a relatively common device in the prior art, so its detailed structure is not disclosed in detail in this application document.

[0038] A central column 18 is rotatably connected to the top center position of the bottom sealing plate 5, and a common disk 20 is fixedly provided on the top of the central column 18. Installation grooves 21 are equidistantly provided on the top of the common disk 20. A storage box 25 for storing backup power supplies is movably inserted into the installation groove 21 along the vertical direction. A universal wheel 17 is provided at the bottom of the storage box 25, and an avoidance groove 251 is provided on the side of the storage box 25. Support columns 40 are symmetrically fixedly provided on the top of the bottom sealing plate 5, and a support disk 37 is fixedly provided on the top of the support column 40. A central tube 36 is fixedly provided and connected to the top center position of the support disk 37. A top connecting tube 33 is fixedly provided on the top of the central tube 36, and an auxiliary supporting component is provided on the top connecting tube 33 when the backup power supply supplies power to the distributed controller main body 16. The outer wall of the central column 18 is provided with a mechanical switching component that automatically moves the other backup power supply to connect to the distributed controller main body 16 when one of the backup power supplies fails and cannot supply power. The interior of the central tube 36 is hollow to facilitate the insertion of the central column 18 described below.

[0039] The power supply contacts 22 are symmetrically fixedly arranged at the bottom of the common box 6, and the power supply contacts 22 are connected to the terminals of the distributed controller body 16. The auxiliary support assembly includes a support plate 32, an extended electromagnet 31, a top arc bar 34, and a bottom arc bar 35. A stepped groove 371 is opened at the top edge of the support plate 37, and a protruding electromagnet 31 is fixedly arranged at the middle position of the top of the stepped groove 371.

[0040] The extending electromagnet 31 is a mature component in the prior art, and therefore is not disclosed in this application document. The specific structure includes a coil winding, an electromagnet core, a fixed frame, and a moving iron core. When current passes through the coil winding, the electromagnet core generates a magnetic field, attracting or pushing the moving iron core to extend or retract it. The fixed frame supports the entire device and provides mechanical stability to ensure that the moving iron core can move smoothly under the action of the magnetic field.

[0041] When the extending electromagnet 31 is powered on, its moving iron core will extend. When the extending electromagnet 31 is powered off, the moving iron core of the extending electromagnet 31 will retract. A support plate 32 is fixedly provided at the output end of the extending electromagnet 31. Therefore, when the extending electromagnet 31 is powered off, the extending end of the extending electromagnet 31 will drive the support plate 32 to retract.

[0042] Auxiliary columns 39 are symmetrically fixed on the side of the support plate 32, and a guide block 38 is movably inserted into the other end of the auxiliary column 39. The bottom of the guide block 38 is fixedly set on the top of the step groove 371. The auxiliary columns 39 and the guide block 38 cooperate to assist the support plate 32 in horizontal movement, and the setting of multiple groups of auxiliary columns 39 provides auxiliary support for the support plate 32, thereby reducing the degree of deformation of the support plate 32 caused by the weight of the backup power supply.

[0043] Arc grooves 331 are equidistantly provided on the side of the top connecting tube 33 in the vertical direction, a top arc bar 34 is fixedly welded to the side of the arc groove 331 located at the top of the top connecting tube 33, a bottom arc bar 35 is fixedly provided on the side of the arc groove 331 located at the bottom of the top connecting tube 33, and the power supply lines of the protruding electromagnet 31 are respectively connected to the top arc bar 34 and the bottom arc bar 35, a partition plate 30 is fixedly provided in the middle position of the inner cavity of the storage box 25, and a vertical rod 26 is fixedly provided vertically to the side of the partition plate 30 in the inner cavity of the storage box 25.

[0044] Horizontal contacts 24 are symmetrically fixed on the top of the vertical rod 26, and vertical contacts 27 are vertically fixed on the side of the avoidance groove 251 of the vertical rod 26. The vertical contacts 27 and the horizontal contacts 24 are connected in parallel to the power socket 29 through wires. A backup power supply is placed in the storage box 25 on the other side of the partition plate 30. The backup power supply is inserted into the power socket 29 through a double-ended wire with a plug. Finally, the vertical contacts 27 and the horizontal contacts 24 can both be powered. The vertical contacts 27 and the horizontal contacts 24 are arranged in pairs.

[0045] The storage box 25 is fixed with a driven plate 28 on the bottom side of the avoidance groove 251. The vertical contact 27 is arranged to be an arc-shaped surface at one end away from the vertical rod 26, which is used to fit the arc-shaped top arc bar 34 and the side of the bottom arc bar 35. The material of the vertical contact 27, the power supply contact 22 and the horizontal contact 24 is selected to be metallic copper.

[0046] The mechanical switching assembly includes a trigger plate 7, a vertical column 8, a horizontal bevel gear 19, a vertical bevel gear 12, a driven gear 14, and a driving gear rod 9. The vertical columns 8 are symmetrically fixed at the bottom edge of the trigger plate 7. A connecting ring 10 is fixedly provided on the outer wall of the vertical column 8. The outer wall of the connecting ring 10 is fixedly connected to one end of a lightweight spring 11, and the other end of the lightweight spring 11 is fixedly connected to the top of the bottom sealing plate 5. When the lightweight spring 11 is at its original length, the trigger plate 7 at the top of the vertical column 8 is at a certain height, and the elastic stiffness of the lightweight spring 11 is selected to be relatively small, so that the backup power supply can press the trigger plate 7 downward due to gravity.

[0047] A driving gear rod 9 is fixedly provided at one end of the bottom of the trigger plate 7 away from the vertical column 8, and a driven gear 14 is stably meshed on the side of the driving gear rod 9. A one-way bearing 15 is fixedly provided at the center of the driven gear 14. A horizontal column 13 is interference inserted into the inner wall of the one-way bearing 15, and a vertical bevel gear 12 is fixedly provided at the other end of the horizontal column 13. A horizontal bevel gear 19 is stably meshed on the side of the vertical bevel gear 12. The installation direction of the one-way bearing 15 needs to be set appropriately. When the driving gear rod 9 moves downward, the driven gear 14 can drive the horizontal column 13 to rotate through the one-way bearing 15, thereby avoiding the common disk 20 from rotating through the relevant structure when the trigger plate 7 is reset due to the lightweight spring 11.

[0048] The horizontal bevel gear 19 is fixedly connected to the outer wall of the center column 18. The setting of the vertical bevel gear 12 and the horizontal bevel gear 19 can transmit the displacement of the trigger plate 7 in the vertical direction to the common disk 20, so that the common disk 20 rotates. If necessary, the number of teeth of the driven gear 14 and the driving gear rod 9 needs to be set appropriately so that when the driving gear rod 9 moves down to the extreme position, the common disk 20 can rotate ninety degrees. The bottom sealing plate 5 is provided with a guide groove 51 at the downward position of the driving gear rod 9 for guiding the vertical displacement of the driving gear rod 9.

[0049] A support frame 23 is fixed with bolts on the top of the outer wall of the storage box 25. The top-view cross-sectional shape of the support frame 23 is similar to the top-view cross-sectional shape of the mounting groove 21. The top-view cross-sectional area of ​​the support frame 23 is larger than the top-view cross-sectional area of ​​the mounting groove 21. When the bottom of the storage box 25 is not supported, the support frame 23 will overlap the top of the storage box 25. When the bottom of the storage box 25 is supported, the bottom of the support frame 23 will be at a certain distance from the top of the common plate 20.

[0050] The material of the top arc bar 34 and the bottom arc bar 35 is metallic copper, and the total arc length of the top arc bar 34 and the bottom arc bar 35 is less than one quarter of the total arc length of the top connecting tube 33. Because four groups of storage boxes 25 are arranged on the top of the common plate 20, when a storage box 25 is under the power supply contact 22, the vertical contact 27 on the adjacent storage box 25 does not contact the top arc bar 34 and the bottom arc bar 35.

[0051] The specific implementation steps and principles of the present invention are as follows:

[0052] In the initial state, multiple installation boxes 1 are equipped with multiple backup power supplies, and the backup power supplies are connected to the power socket 29 through connecting wires with plugs at both ends. At this time, the horizontal contacts 24 and the vertical contacts 27 are energized. During the initial installation, the backup power supply below the power supply contact 22 is normal, and the vertical contact 27 supplies power to the extendable electromagnet 31 through the top arc bar 34 and the bottom arc bar 35. At this time, the extendable electromagnet 31 extends, and the driven plate 28 below the power supply contact 22 is supported by the support plate 32. The horizontal contact 24 is in contact with the power supply contact 22. At this time, the distributed controller body 16 is powered, and when the trigger plate 7 is not under pressure, the lightweight spring 11 is in its original length state, maintaining the trigger plate 7 at a certain height.

[0053] When the backup power supply below the power supply contact 22 fails and cannot continue to supply power, the extendable electromagnet 31 is powered off and automatically drives the support plate 32 to retract. At this time, the driven plate 28 below the power supply contact 22 is not supported, and the universal wheel 17 at the bottom of the storage box 25 below the power supply contact 22 is pressed to the trigger plate 7. The trigger plate 7 drives the driven gear 14 to rotate by driving the gear rod 9. The driven gear 14 drives the common disk 20 at the top of the center column 18 to rotate through the horizontal column 13, the vertical bevel gear 12 and the horizontal bevel gear 19. At this time, the common disk 20 drives the old backup power supply to rotate. At this time, the storage box 25 with the old faulty power supply installed inside moves while moving downward, and the universal wheel 17 at its bottom moves along the top of the trigger plate 7.

[0054] During this process, the universal wheel 17 at the bottom of the storage box 25 storing the new backup power source moves along the top of the support plate 37. When the universal wheel 17 at the bottom of the old storage box 25 moves away from the top of the trigger plate 7, the trigger plate 7 drives the driving gear rod 9 to move upward under the reset of the lightweight spring 11. Due to the presence of the one-way bearing 15, the driving gear rod 9 drives the driven gear 14 to rotate when it moves upward, and the driven gear 14 will not drive the horizontal column 13 to rotate. The vertical contact 27 of the new storage box 25 gradually contacts the top arc bar 34 and the bottom arc bar 35, and the protruding electromagnet 31 is powered by the top arc bar 34 and the bottom arc bar 35. The support plate 32 is extended again, and the driven plate 28 of the new storage box 25 moves to the top of the support plate 32 again. At this time, the new horizontal contact 24 contacts the power supply contact 22, and the distributed controller body 16 is powered.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
