Description

Technical Field

[0001] This invention relates to the field of secondary battery technology, specifically to a distributed power storage device. Background Technology

[0002] Distributed power storage devices refer to miniaturized energy storage systems that are deployed in a decentralized manner near the user side, power source side, or load center. They are flexibly configured through modular design and can operate independently or in clusters. Their main functions include smoothing out fluctuations in renewable energy output, optimizing energy dispatch, improving power supply reliability, and reducing electricity costs. Most of them are used indoors or under shaded conditions, and they are the "capillaries" of the new power system. A Chinese patent discloses a distributed power storage device, application number: CN202222072903.3. This device can achieve more comprehensive heat dissipation, improve the heat dissipation effect, and enable the energy storage platform to maintain normal operation. However, most of the current distributed energy storage devices rely on wind power for cooling, which cannot maintain balance. Furthermore, when multiple batteries work together, whether charging or discharging, it is impossible to ensure a relatively uniform internal temperature. In addition, the heat dissipation noise is loud and easily affected by external factors. Most large servers nowadays use water cooling to dissipate heat, improve operating efficiency and ensure battery life. However, under normal circumstances, the refrigerant cannot meet the requirements and needs to be replaced every six months after long-term use, which cannot achieve the normal lifespan guarantee and results in high maintenance costs. If the internal temperature cannot be kept even, it will cause individual damage to the battery, affecting the overall efficiency and requiring regular maintenance and inspection, thus preventing efficient charging and discharging operations.

In addition, the flow-limiting and guiding functions of limit valves, inserts, horizontal grooves, embedded pipes, diverter valves, branch pipes, bottom cavities, straight pipes, heat exchange pipes, heat insulation pipes, and grid pipes, as well as the balancing and supplementing function of the back box, can circulate and utilize the heat dissipated during the operation of the battery. It can transform the heat dissipated during the operation of the battery into the driving force for the circulation of carbon dioxide. It can complete the heat exchange of the battery without additional energy consumption and external driving equipment, realizing the recovery and utilization of energy. While saving energy, it reduces electrical costs and achieves cost reduction and efficiency improvement. Its modular and flexible characteristics not only meet the economic needs of individual users, but also provide underlying protection for grid security and energy transformation. It can effectively improve its promotion efficiency and multi-scenario adaptability, and more efficiently realize the multiple values ​​of cost reduction on the user side, grid stability on the grid side, and low carbon on the energy side. On the other hand, it enables synchronous heat exchange of the batteries, forcing the internal and external circulation of heat exchange within the enclosure. This not only effectively improves the efficiency of heat exchange but also makes the heat exchange process more synchronized and compatible with the battery's operation. Furthermore, the heat exchange rate rises and falls synchronously with the battery's heat generation, significantly improving the timeliness, effectiveness, and adaptability of the heat exchange process. This makes the heat exchange process more efficient and stable. In addition, the synchronous flow guiding effect of the air distribution strips, intake valves, intake pipes, exhaust valves, and air guide seats can be combined with the circulation and conversion of carbon dioxide to form a dual heat exchange mechanism of internal circulation and internal and external exchange. This not only effectively improves the temperature balance inside each compartment, allowing each battery to work more efficiently and stably and extending the effective service life of the batteries, but also further promotes more efficient and smooth circulation of carbon dioxide.

Through the strips, flow-limiting boxes, perforated plates, and compression springs, the flow of carbon dioxide can be limited and guided, improving the ease of disassembly and assembly of the compartments.

[0015] 2. Equipped with a synchronous limiting mechanism, the sliding block, lifting frame, air cushion, and protective pad work together to form a flexible encapsulation and lifting structure, providing flexible support and protection for the battery. This not only effectively improves the comprehensiveness and stability of the protection work, but also, with the bidirectional elastic limiting effect of the mounting box, sliding plate, push rod, limiting box, support plate, limiting plate, and support spring, it provides double elastic support for the battery. This effectively mitigates and weakens the external impact on the battery during transportation and use, effectively reducing the probability of damage during transportation and significantly lowering the loss rate. This makes the power storage device easier to promote and transport. Moreover, it effectively offsets the vibration generated during transportation and use, effectively ensuring the wiring stability of the battery during use, and effectively avoiding wiring detachment, confusion, or even short circuits. While ensuring the convenience of using the power storage device, it also makes its use more stable and safe. In addition to the conversion effect of the communication between the cavities and the telescopic pipes, on the one hand, the directness and effectiveness of the heat exchange work can be further improved, and the heat emitted during the operation of the battery can be more fully recovered, and on the other hand, the elastic limiting protection force received by the battery can be more balanced and stable, in addition to the connecting effect of the conductive seat, the conductive rod, the plug, the conductive terminal, the grafting line and the connecting wire, and the communication and flow guiding effect of the through hole, a synchronous on-off mechanism can be formed, the synchronous transmission effect of the mounting box, the sliding plate, the push rod and the through hole can be fully utilized, the running safety during the operation of the battery is provided with bottom layer protection, the safety during the use of the battery is improved, the faulty part of the battery can be timely physically isolated, the spread of the fault can be effectively avoided, and the synchronous adjustment effect of the limiting box, the supporting plate, the limiting plate, the supporting spring, the screw rod, the gap and the limiting rod can be matched, the protection node can be limited, and the needs for energy storage and power supply stability and running safety can be simultaneously considered.

[0023] The working principle and usage process of this invention: Before using this distributed power storage device, first place the box 1 stably on the ground, open the box 1, pull out the cabinet 202, and according to actual needs, install the corresponding specifications and quantity of batteries 16 into the hanging frame 302 in sequence. Then, connect the batteries 16 inside the same slide 301 in series and connect their positive and negative terminals to the conductive base 307 through the grafting wire 312. Under initial conditions, under the elastic force of the support spring 319, the support plate 317 will push the slide 301 through the limiting rod 322 to provide it with elastic support, causing the plug 310 to be inserted and connected to the conductive seat 307. Under the connection of the conductive rod 309, the corresponding conductive terminal 311 is connected to the positive and negative terminals of the battery 16 connected in series inside the slide 301. Here, the limiting plate 318 can be moved by rotating the screw 320 to press the support spring 319 and adjust the elastic support it provides to the support plate 317, so as to limit the pressure that needs to be overcome to disconnect this part of the battery 16 during subsequent work. During the process of resetting each cabinet 202, the insert tube 204 will be inserted into the corresponding transverse groove 206, which will press against the corresponding strip 222, overcome the air pressure on the other side of the strip 222, and push the strip 222 to slide along the transverse groove 206, so that it no longer blocks the embedded tube 207. Finally, the embedded tube 207 and the insert tube 204 will be connected to the transverse groove 206 at the same time. Similarly, the straight tube 211 will also be inserted into the corresponding flow-blocking box 223, overcome the elastic force of the compression spring 225 on the orifice plate 224, and finally the grid tube 215 and the straight tube 211 will be connected to the flow-blocking box 223 at the same time, forming a complete flow circuit for carbon dioxide. Next, an appropriate amount of carbon dioxide is added to the top chamber 14. During normal use, when some carbon dioxide absorbs heat and vaporizes and expands, it encroaches on the storage space of another part of carbon dioxide, causing the other part of carbon dioxide to liquefy under pressure. When the pressure on the flowing carbon dioxide exceeds the critical pressure, the top chamber 14 can provide a buffer storage space for the flowing carbon dioxide, temporarily storing the excess carbon dioxide in this state. When the pressure of the flowing carbon dioxide is insufficient, the temporarily stored carbon dioxide is released to compensate. A carbon dioxide cylinder can also be connected here to flexibly meet storage needs. Carbon dioxide injected into the top chamber 14 enters the grid tube 215 through the connecting pipe 15, and then flows along the heat exchange tube 213 into the insulation tube 214. With the connection of the diversion valve 208 and the branch pipe 209, it flows sequentially into each connected transverse groove 206, and then into the partition seat 201 with the connection of the embedding pipe 207. Subsequently, with the connection of the embedding pipe 207 on the other side, it enters the transverse groove 206 on the other side, passes through the limit valve 203 and the insertion pipe 204 into the bottom cavity 210, and then flows into the partition cavity 304 through the telescopic pipe 305 to replenish the carbon dioxide. It is important to note that the pressure of the carbon dioxide introduced should be controlled to ensure that it is in a state of gas-liquid equilibrium, and that the pressure that each structure through which the carbon dioxide flows can withstand is greater than 7.5 MPa, so as to stably meet the pressure requirements during the carbon dioxide flow process. Then, the conductive terminals 311 on each cabinet 202 can be connected in series by connecting wire 323, and the box 1 with the battery 16 assembled can be transported in a centralized manner. After it is transported to the designated working position, it can be connected to the power grid and connected to the external power supply channel according to actual needs. Then, this energy storage device can be put into use. During normal use of this energy storage device, as the load of the battery 16 changes during use, it will inevitably dissipate corresponding heat. This heat will be directly absorbed by carbon dioxide, thereby breaking the gas-liquid balance of carbon dioxide inside the cavity 304. This carbon dioxide will vaporize under the action of external temperature, absorb more heat, and enter the bottom cavity 210 through the telescopic tube 305 under pressure. Similarly, due to the action of temperature, the carbon dioxide inside the bottom cavity 210 will also vaporize. Subsequently, the vaporized carbon dioxide will enter the flow-blocking box 223 through the straight pipe 211 under pressure, pass through the holes on the orifice plate 224, enter the grid tube 215 through the flow-blocking box 223, and then flow into the heat exchange tube 213 along the grid tube 215. Since the back box 212 is directly connected to the external atmosphere and is no longer constrained by the external temperature, the vaporized carbon dioxide will gradually liquefy under pressure during the flow along the heat exchange tube 213 and then flow into the heat insulation tube 214. Under the flow-limiting and guiding action of the diversion valve 208 and the branch pipe 209, the liquefied carbon dioxide will pass through the diversion valve 208 and the branch pipe 209 and enter the transverse grooves 206 connected to it in sequence. Then, it will enter the space inside the corresponding partition 201 located at the top of the slide plate 205 through the embedded pipe 207 connected to it, and enter the transverse groove 206 on the other side through the connection of the embedded pipe 207 on the other side. Under the flow-limiting and guiding action of the limit valve 203 and the insertion pipe 204, it will flow back into the bottom cavity 210 and flow into the partition cavity 304 through the telescopic pipe 305. After the liquefied carbon dioxide flows back into the bottom cavity 210 and the partition cavity 304, it will be constrained by the external temperature again. During the flow, it will absorb the heat emitted by the battery 16 during operation, gradually vaporize again, and start a new round of circulation under pressure. During the operation of the battery 16, it will circulate and cool it down. The heat dissipated by the battery 16 during operation is used as the driving force to force internal and external heat exchange. Similarly, in the aforementioned process, as the heat emitted during the operation of the battery 16 causes its external temperature to rise, the carbon dioxide pressure inside the partition 201 at the top of the slide plate 205 will also rise accordingly. Under the pressure of carbon dioxide, the slide plate 205 will overcome the elastic force of the spring 217 and slide down the slide bar 216, converting some of the heat emitted during the operation of the battery 16 into the elastic potential energy of the spring 217 for temporary storage. As the liquefied carbon dioxide enters the bottom cavity 210 and the partition cavity 304 to force cooling, under the pressure fluctuation, the pressure on the top of the slide plate 205 will decrease accordingly, and the spring 217 will push the slide plate 205 to reset and rise, releasing the stored energy. As a result, the skateboard 205 will move up and down repeatedly during the flow of carbon dioxide. Under the flow restriction and guidance of the intake valve 219 and the intake pipe 220, as the skateboard 205 moves up and down repeatedly, the external airflow will pass through the filter screen 12 and enter the back box 212 under its pull. Then, it will pass through the corresponding intake valve 219 and intake pipe 220 and enter the space and air distribution strip 218 located at the bottom of the skateboard 205 inside the partition 201. Then, under the flow-limiting and guiding effect of the exhaust valve 221, the air is discharged through the exhaust valve 221 to assist the heat exchange of the battery 16 at the bottom. At the same time, under the guidance of the air guide seat 226, some airflow will also enter the air guide seat 226. With the connection of the hollow bracket 11, it will be discharged through each air guide seat 226, which will promote heat exchange inside the box 1 and equalize the temperature in various parts of the box 1. Finally, the airflow will pass through the partition 13 and be discharged into the atmosphere. As the slide plate 205 reciprocates up and down during the aforementioned process, external airflow is continuously drawn into the back box 212, which ensures that the temperature outside the heat exchange tube 213 remains at a relatively low temperature. This significantly improves the liquefaction heat exchange effect of carbon dioxide inside the heat exchange tube 213. Similarly, during the reciprocating up and down process of the slide plate 205, when it rises, it draws external air on the one hand, and the energy stored in the spring 217 is released again and converted into pressure internal energy during the flow of carbon dioxide. This compensates for and enhances the pressure of the liquefied carbon dioxide flowing into the partition seat 201, promoting a more stable circulation flow. It should be noted that: since the liquefied carbon dioxide needs to flow along the heat insulation pipe 214, it will flow into each compartment 201 in sequence. That is, the time when it flows into each bottom cavity 210 and compartment 304 will be offset, which will cause the temperature inside each compartment 202 to show a regular rhythm. Then, under the heat dissipated by the battery 16 and the limiting action of the spring 217, each slide 205 will alternately perform reciprocating up and down motion, continuously pulling the external airflow, and alternately compensating and enhancing the pressure of the liquefied carbon dioxide inside each compartment 201, so as to promote a more continuous and stable circulation of carbon dioxide. Furthermore, during the gas-liquid conversion of carbon dioxide and the flow of air, the box 1 undergoes dual internal and external heat exchange, balancing the internal temperature of each compartment 202. This allows the battery 16 to work more efficiently and stably, extending its service life. Since the initial state of the charged carbon dioxide is a gas-liquid equilibrium state, during the operation of the battery 16, as long as the battery 16 dissipates heat, its equilibrium state can be easily broken, resulting in rapid heat exchange. During the dormant period of the battery 16, when it does not dissipate heat, the pressure of carbon dioxide in each location will spontaneously balance, returning to a gas-liquid equilibrium state, ready for the next heat exchange. During the aforementioned circulation of carbon dioxide, when it flows into the cavity 304, it will squeeze the air cushion 303, causing the air cushion 303 to expand and squeeze the inner battery 16, making the battery 16 fit more closely with the air cushion 303. While providing all-round elastic fixation for the battery 16, the heat emitted by the battery 16 can be more fully absorbed by the carbon dioxide. Meanwhile, with the through hole 315 connected, some carbon dioxide will flow into the mounting box 308, which will squeeze the sliding plate 313 and provide elastic support to the pad 306 through the push rod 314. In conjunction with the limit rod 322, the slide block 301 will be fixed in both directions. In addition, the air cushion 303 provides elastic coverage to the battery 16, which can achieve double weakening of external disturbance forces and ensure the stability of the battery 16 during operation. During the long-term operation of the storage battery 16, if the storage battery 16 exceeds the load limit due to an accident or other factors, the temperature will rise abnormally. The abnormally rising temperature will cause the carbon dioxide pressure inside the cavity 304 to rise abnormally. Correspondingly, the pressure of carbon dioxide on the sliding plate 313 will also rise. When it is sufficient to overcome the elastic support given to the slide 301 by the support spring 319, it will push the slide 301 to slide through the push rod 314, so that the plug 310 is disengaged from the conductive seat 307, cut off the connection of the storage battery 16, and prevent the abnormal spread. In the event of an accidental fire during the long-term operation of the battery 16, the air cushion 303 will also be damaged, and carbon dioxide will gush out through the damaged area, using chemical inhibition and physical cooling to quickly extinguish the fire and prevent the fault from spreading. Finally, carbon dioxide can be used as a heat exchanger, and different heat exchangers or mixtures can be used depending on requirements and site conditions.
