Description

Technical Field

[0001] The present invention relates to the technical field of energy storage, and in particular, to an energy storage power station composed of multiple power supply units. Background Art

[0002] An energy storage power station is a facility that can store and release electrical energy, and is usually used to balance the power supply and demand of the power grid, improve the stability of the power grid, and utilize renewable energy. It often has multiple power supply units, because this can improve the flexibility and reliability of the system. Multiple power supply units allow the power station to perform charge and discharge operations at different time periods, so as to better adapt to the fluctuations of power demand. In addition, multiple power supply units can disperse risks, ensuring that when one unit fails, other units can still operate normally, guaranteeing the continuity of power supply.

[0003] In the prior art, multiple power supply units of an energy storage power station are often fixed and concentrated on the energy storage power station. When one of the power supplies accidentally fails and catches fire, it will affect other batteries. Moreover, when the battery catches fire spontaneously, the fire is likely to spread to other batteries, resulting in an increase in the overall fire risk. At the same time, since the circuit of the faulty battery is still connected to the main controller, it may cause the current to continue to flow, further exacerbating the harm of the fire and making it difficult to control the fire. In addition, the concentrated battery layout also limits the flexibility of fault management and maintenance, making emergency response and fault isolation more difficult, thus posing a serious threat to the safety and reliability of the entire energy storage system. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, multiple power supply units are often fixed and concentrated on the energy storage power station. When one of the power supplies accidentally fails and catches fire, it will affect other batteries. Moreover, when the battery catches fire spontaneously, the fire is likely to spread to other batteries, resulting in an increase in the overall fire risk. At the same time, since the circuit of the faulty battery is still connected to the main controller, it may cause the current to continue to flow, further exacerbating the harm of the fire and making it difficult to control the fire.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. A vertical plate is arranged in the middle of the side surface of the storage box in the present invention, and horizontal plates are arranged at equal intervals along the vertical direction on the vertical plate. Multiple groups of horizontal plates divide the inner cavity of the storage box into multiple independent cavities. A power supply box for storing independent power sources is arranged inside the cavity, and a composite release component based on temperature change is arranged inside the power supply box. When an independent power source inside the power supply box accidentally catches fire, the composite release component can automatically physically separate the circuit between the independent power source and the main controller, which has significant advantages. It can effectively prevent the continuous flow of current, prevent the further spread and expansion of the fire, reduce the fire risk, and this physical separation mechanism ensures the safety of other power supply units and prevents the overall system failure caused by a chain reaction. The rapid disconnection of the independent power source helps to isolate the fault source in a timely manner, facilitating fault troubleshooting and maintenance, and improving the safety and reliability of the energy storage system.

[0018] 2. A composite release component is arranged inside the power supply box in the present invention. When an independent power source inside the power supply box accidentally catches fire, the power supply box where the accidental combustion of the internal independent power source occurs can be horizontally moved and ejected from the entire inner cavity of the storage box, facilitating maintenance personnel to quickly observe the position of the faulty independent power source with the naked eye, and facilitating maintenance personnel to quickly perform on-site processing and replace the damaged power supply unit, improving the overall maintenance efficiency and safety of the energy storage system.

[0019] 3. The present invention is provided with a composite release component inside the power supply box. The side of the power supply box is provided with heat dissipation holes in a rectangular array for the necessary heat dissipation of the independent power module. When an independent power supply inside the power supply box accidentally catches fire, on the one hand, the composite release component will horizontally move and eject the power supply box where the accidental combustion of the internal independent power supply occurs from the entire inner cavity of the storage box. On the other hand, it will automatically close the heat dissipation holes in the rectangular array due to the temperature, making the inside of the power supply box a closed environment, cutting off the oxygen supply during the combustion of the independent power supply inside the power supply box, effectively suppressing the fire and preventing the spread of the fire. The formation of the closed environment reduces the impact of the fire on the surrounding power units and improves the overall safety of the energy storage system. This design helps to reduce the losses and maintenance costs caused by the fire.

[0020] 4. The present invention is provided with an adjustment component inside the vertical cylinder. The adjustment component can adjust the action temperature of the entire composite release component, allowing for flexible setting of the trigger temperature of the composite release component according to different application scenarios and ambient temperatures, improving the adaptability of the system. By precisely adjusting the action temperature, false triggering or delayed triggering can be avoided, thereby enhancing the reliability and safety of the system. This design ensures that under various conditions, the composite release component can act at the optimal temperature point, providing the most effective fire prevention and control measures, and improving the overall performance and safety of the entire energy storage system.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] Refer to Figure 1-13, An energy storage power station composed of multiple power units, including a storage box 6, a power box 16, and an independent power supply 23. Support feet 7 are symmetrically and fixedly arranged at the bottom of the storage box 6. A vertical plate 5 is fixedly arranged at the middle position of the top inner cavity of the storage box 6. Horizontal plates 2 are fixedly arranged at equal intervals on both sides of the vertical plate 5. A guide groove 3 is opened at the top of the horizontal plate 2. A guide block 1 is fixedly arranged at the end of the guide groove 3. An extension rail 61 is fixedly arranged at one end of the guide groove 3 away from the guide block 1. The top of the extension rail 61 is flush with the top of the guide groove 3. The overall structure of the support foot 7 includes side plates and a bottom plate. The side plates are welded to both sides of the bottom plate, and the two groups of side plates are welded to the side of the storage box 6. The bottom height of the support foot 7 is lower than the bottom height of the storage box 6. Multiple bolt holes are arranged at the top of the support foot 7, which is convenient for users to use anchor bolts to fix the entire storage box 6 on the ground. Moreover, since the bottom height of the support foot 7 is lower than the bottom height of the storage box 6, it can prevent the main controller 10 at the bottom of the storage box 6 from getting damp.

[0038] The main controller 10 generally includes structures such as a power management unit, a communication module, a data processing unit, and a monitoring interface, etc. The power management unit is responsible for regulating and distributing electric energy to ensure the stable operation of the system; the communication module is used for data transmission and instruction reception with other devices and a remote monitoring center; the data processing unit analyzes and processes the collected data to provide real-time status and performance monitoring; the monitoring interface provides an interaction platform between the user and the system, displaying the operating status and alarm information. The main controller 10 is a common device in the prior art, so its detailed structure is not disclosed in this application document.

[0039] A guide column 14 is movably inserted into the side of the guide block 1. When setting the guide block 1, an appropriate length is required to assist the lateral movement of the guide column 14. One end of the outer wall of the guide column 14 is fixedly connected to one end of a release spring 13, and the other end of the release spring 13 is fixedly connected to the side of the guide block 1. A fixed block 15 is fixedly arranged at the end of the guide column 14 away from the guide block 1. The guide block 1 and the fixed block 15 are the same width as the guide groove 3 and the extension rail 61. The fixed block 15 is fixedly connected to the bottom of the power box 16. When the release spring 13 is in its original length, the power box 16 is in a state of popping out from the inner cavity of the storage box 6.

[0040] At this time, the fixed block 15 is on the extension rail 61. When the combustion temperature of the independent power supply 23 inside a certain power box 16 reaches a certain level, the helium gas in the inner cavity of the vertical cylinder 28 inside the power box 16 expands rapidly, driving the driving disk 34 to move upward, overcoming the pre-tightening force of the control spring 38. The driving disk 34 drives the bottom of the limit column 35 to disengage from the fixing hole 4, and the release spring 13 laterally pops out the power box 16 from the inside of the storage box 6. When the bottom of the limit column 35 moves horizontally along the top of the extension rail 61 when the fixed block 15 is at the top of the extension rail 61, the closing plate 27 continuously maintains the state of closing the heat dissipation holes 17 at this time.

[0041] Inside the power supply box 16, there is an independent power supply 23 stored. On one side of the independent power supply 23 in the inner cavity of the power supply box 16, there is a heat dissipation hole 17 opened. On the side of the heat dissipation hole 17 of the power supply box 16, there is a composite release component that can emergently close the heat dissipation hole 17 and emergently separate the independent power supply 23 from the main controller 10 when the independent power supply 23 accidentally catches fire. On the rear side of the horizontal plate 2, a rear guard plate 11 is fixedly arranged. In the middle position on the side of the rear guard plate 11, a connection socket 12 is fixedly arranged. At the bottom of the inner cavity of the storage box 6, the main controller 10 is fixedly arranged. On the rear side of the storage box 6, an extension frame 9 is fixedly arranged. On the rear side of the extension frame 9, a rear sealing plate 8 is fixedly arranged. There is a gap between the rear sealing plate 8 and the rear guard plate 11. The bottom end of the rear sealing plate 8 is obliquely above the main controller 10. The gap between the rear sealing plate 8 and the rear guard plate 11 is used to accommodate the extension wire of the connection socket 12.

[0042] The connection socket 12 is connected to the main controller 10. On the side of the independent power supply 23, a docking plug 21 is fixedly arranged. The docking plug 21 is movably inserted into the connection socket 12. Both the docking plug 21 and the connection socket 12 are common electronic devices in the prior art and are used for the circuit connection between the independent power supply 23 and the main controller 10.

[0043] The composite release component includes a vertical cylinder 28, a closing plate 281, a driving plate 34, a jacking column 33, a common rod 32, a horizontal rod 31, and a closing plate 27. On the side of the heat dissipation hole 17 in the inner cavity of the power supply box 16, vertical rails 26 are symmetrically and fixedly arranged. On the top of the vertical rails 26 of the power supply box 16, a right-angle protection plate 22 is fixedly arranged. The right-angle protection plate 22 includes a vertical section and a horizontal section. The right-angle protection plate 22 is used to protect the top of the composite release component.

[0044] A closing plate 27 is movably inserted between the two groups of vertical rails 26. The length and height of the closing plate 27 need to be set appropriately. When the closing plate 27 displaces in the vertical direction, it can close the heat dissipation holes 17 in the rectangular array on the outer wall of the power supply box 16. The contact positions between the inner walls of the vertical rails 26 and the closing plate 27 are all smooth surfaces to reduce the resistance when the closing plate 27 displaces in the vertical direction.

[0045] In the middle position on the side of the closing plate 27, a horizontal rod 31 is fixedly arranged. The other end of the horizontal rod 31 is fixedly connected to a common rod 32. On the top of the common rod 32, jacking columns 33 are symmetrically and fixedly arranged. At the bottom of the jacking column 33, a driving plate 34 is fixedly arranged. The diameter of the driving plate 34 is the same as the inner cavity diameter of the vertical cylinder 28. The center position at the bottom of the driving plate 34 is fixedly connected to one end of a limit column 35. The arrangement of the jacking column 33 and the common rod 32 leaves a space at the center position on the top of the driving plate 34 to make way for the adjustment component.

[0046] The bottom of the vertical cylinder 28 is fixedly arranged inside the power supply box 16. A closed disk 281 is fixedly arranged at the top of the vertical cylinder 28. An adjusting component for adjusting the operating temperature of the composite release component is arranged at the center position of the top of the closed disk 281. A support ring 30 is fixedly arranged inside the vertical cylinder 28. The lower end of the limit post 35 extends out of the bottom of the vertical cylinder 28 and the bottom of the power supply box 16 in sequence. An inclined surface 351 is arranged at the bottom of the limit post 35.

[0047] The inner ring diameter of the support ring 30 is smaller than the diameter of the limit post 35. Since the control spring 38 in the adjusting component applies a downward pressure to the driving disk 34, the support ring 30 is used to support the driving disk 34, so as to facilitate a certain space to exist below the vertical cylinder 28 and the driving disk 34 for storing helium.

[0048] Helium is filled below the driving disk 34 in the vertical cylinder 28. A one-way valve 29 is arranged at the bottom of the side of the vertical cylinder 28. The one-way flow direction of the gas inside the one-way valve 29 is from the air to the inner cavity of the vertical cylinder 28, which is convenient for the user to use an air pump to supplement helium into the inner cavity of the vertical cylinder 28 through the one-way valve 29.

[0049] A fixing hole 4 is opened at one end of the guiding groove 3 away from the guiding block 1. The diameter of the fixing hole 4 is the same as the diameter of the limit post 35. The adjusting component includes a control spring 38, a pressing disk 37, and an adjusting bolt 36. The adjusting bolt 36 is screwed into the side of the closed disk 281. The bottom of the adjusting bolt 36 is rotatably connected to the center position of the top of the pressing disk 37. The bottom of the pressing disk 37 is fixedly connected to one end of the control spring 38. The bottom of the control spring 38 abuts against the center position of the top of the driving disk 34. The jacking column 33 passes through the pressing disk 37. Workers can use an Allen bolt to rotate and adjust the adjusting bolt 36, so as to control the depth of the adjusting bolt 36 screwed into the bottom of the closed disk 281, drive the pressing disk 37 to press down, compress the control spring 38 to an appropriate length, and finally adjust the pre-tightening force of the control spring 38.

[0050] A top cover 18 is fixedly arranged at the top of the power supply box 16. A side sealing plate 24 is rotatably connected to the bottom of the side of the power supply box 16. The rotating shaft of the side sealing plate 24 is at the bottom of the side sealing plate 24 and is in a horizontal state. Therefore, when an adjacent power supply box 16 pops out, the side sealing plate 24 can be opened from the side of the power supply box 16, and the faulty or old independent power supply 23 can be pulled out from the side of the power supply box 16. Therefore, the cross-sectional dimension of the side sealing plate 24 is not less than the cross-sectional dimension of the side of the independent power supply 23, which is convenient for the independent power supply 23 to be pulled out from the side of the power supply box 16.

[0051] A stepped hole 19 is opened at the top of the top cover 18. A fixing bolt 20 is screwed into the stepped hole 19. A positioning hole 25 is opened at the top of the side sealing plate 24. The bottom of the fixing bolt 20 is screwed into the positioning hole 25. The stepped hole 19 includes a wide section and a narrow section. The wide end of the stepped hole 19 is used to accommodate the head of the fixing bolt 20, and the top of the top cover 18 is flush with the horizontal plate 2 at its corresponding position.

[0052] The specific implementation steps and principles of the present invention are as follows:

[0053] When actually adjusting multiple adjustment components, workers are required to use hexagon socket bolts to rotate the adjustment bolts 36, thereby controlling the depth of the adjustment bolts 36 screwed into the bottom of the closing disk 281, and finally adjusting the preload force of the control spring 38. When the entire energy storage power station is in standby mode, multiple power boxes 16 are completely inside the independent cavity of the storage box 6, and multiple closing plates 27 are obliquely below the heat dissipation holes 17 of the array. The power box 16 is in an open state, and the independent power supply 23 in the inner cavity of the power box 16 dissipates heat normally, the release spring 13 is compressed, and the limit column 35 is inserted into the fixing hole 4.

[0054] When the combustion temperature of the internal independent power supply 23 of a power box 16 reaches a certain level, the helium in the inner cavity of the vertical cylinder 28 inside the power box 16 expands rapidly, driving the drive disk 34 to move upward, overcoming the preload force of the control spring 38. The drive disk 34 drives the bottom of the limit column 35 to disengage from the fixing hole 4, releasing the spring 13 to eject the power box 16 laterally from the storage box 6.

[0055] During this period, the docking plug 21 is separated from the connecting socket 12. On the other hand, the driving disk 34 drives the closing plate 27 to move up along the vertical rail 26 through the lifting column 33, the common rod 32, and the horizontal rod 31. The closing plate 27 closes the heat dissipation holes 17 of the rectangular array, closes the power box 16, and the fixed block 15 and the limit column 35 move along the top of the extension rail 61 to keep the closing plate 27 closing the heat dissipation holes 17. At this time, the flame inside the power box 16 will gradually go out due to lack of oxygen. After waiting for a certain period of time, the worker uses an Allen wrench to unscrew the fixing bolt 20 from the positioning hole 25. At this time, the side sealing plate 24 can be turned out from the side of the power box 16, and the independent power supply 23 can be pulled out from the power box 16.

[0056] 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.
