Description

Technical Field

[0001] This application relates to the field of liquid-cooled energy storage technology, and in particular to a high-safety liquid-cooled energy storage device. Background Technology

[0002] High-safety liquid-cooled energy storage devices are equipment that use liquid cooling technology to improve the safety and efficiency of energy storage systems. By directly immersing the energy storage battery in coolant, the device achieves direct, rapid, and sufficient cooling of the battery, ensuring that the battery operates within the optimal temperature range, thereby extending the battery's lifespan and improving overall safety performance.

[0003] Instability during operation of a high-safety liquid-cooled energy storage device can lead to collisions between internal components, causing problems such as electrolyte leakage. Furthermore, instability can loosen connections, resulting in localized overheating and potentially posing safety hazards such as fires. Unstable operation can also interfere with the liquid cooling system, causing the energy storage device to malfunction due to excessive temperature or even thermal runaway, which poses an extremely serious threat to the safe operation of the energy storage device. Utility Model Content

[0004] This application discloses a high-safety liquid-cooled energy storage device, aiming to solve the technical problems that high-safety liquid-cooled energy storage devices are unstable during operation, which can cause internal components to collide and lead to electrolyte leakage; loosen the connection parts, causing local overheating and even fire; and interfere with the liquid cooling system, leading to device failure due to high temperature.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A high-safety liquid-cooled energy storage device includes a liquid-cooled energy storage cabinet. A fixed base is fixedly connected to the bottom of the liquid-cooled energy storage cabinet. Multiple vertical frames are fixedly connected to both walls of the liquid-cooled energy storage cabinet. Symmetrical horizontal frames are fixedly connected to the top of each vertical frame, and the bottom of each horizontal frame is fixedly connected to the top of the liquid-cooled energy storage cabinet. Lifting lugs are fixedly connected to the connection points of the horizontal and vertical frames. The bottom of each lifting lug is fixedly connected to both sides of the top of the liquid-cooled energy storage cabinet. Multiple battery module mounting plates are fixedly connected to the inner wall of the liquid-cooled energy storage cabinet, and battery modules are mounted on the top of each battery module mounting plate. Mounting frames are fixedly connected to both walls of each battery module, and symmetrical fixing nuts are fixedly connected to the top of each mounting frame. Symmetrical holes are formed on each battery module mounting plate, with the outer side of the fixing nuts located inside the holes, and the fixing nuts securely connect the mounting frames to the battery module mounting plates.

[0007] Equipped with a fixed base, vertical frame, horizontal frame, lifting lugs, battery module mounting plates, battery modules, and fixing nuts, the liquid-cooled energy storage cabinet supports various equipment and energy storage battery modules. Lifting lugs are located on both sides of the vertical and horizontal frames for connecting hooks to complete lifting operations. The fixed base allows for secure fixing to various ground surfaces. Fixing nuts tightly connect the battery modules to the battery module mounting plates, improving equipment reliability. Fixing the battery modules during operation provides the energy storage device with strong strength and vibration resistance. Four lifting lugs on top of the liquid-cooled energy storage cabinet facilitate hoisting and improve transportation reliability. Screws connect the fixed base to the ground to maintain the stability of the energy storage device, giving it strong environmental adaptability.

[0008] In a preferred embodiment, each of the multiple battery module fixing plates and fixing brackets has symmetrical rectangular holes. Each rectangular hole contains a loosening detection component, which includes symmetrical clamping plates. The opposite sides of the clamping plates contact the top sides of the fixing nut. A telescopic rod is fixedly connected to the side of each clamping plate away from the fixing nut, and a compression spring is fixedly connected to the side of each clamping plate away from the fixing nut. The compression springs are located outside the telescopic rods. A sliding plate is fixedly connected to the end of each compression spring and telescopic rod away from the clamping plate. Symmetrical sliding grooves are formed inside each rectangular hole, and the sliding plate is located inside the sliding groove. The components are movably connected, and symmetrical movable rods are movably connected to the front side of the sliding plate. The movable rods are located in front of the clamping plate. A temporary pressure plate is movably connected to the side of the two movable rods near the clamping plate. The temporary pressure plate is located above the fixing nut. A sliding groove plate is movably connected to the side of the temporary pressure plate away from the clamping plate. The bottom of the sliding groove plate is fixedly connected to the top of the fixing frame. A detection needle is provided on the side of the clamping plate away from the telescopic rod, and the top of the detection needle contacts the side of the clamping plate away from the telescopic rod. A moving detector is fixedly connected to the side of the detection needle away from the telescopic rod. The bottom end of the moving detector is fixedly connected to the top of the battery module fixing plate.

[0009] By incorporating a loosening detection component, when the fixing nut becomes loose, the clamping plate, initially in a normally fixed state, maintains a stable relative position between the clamping plate and the fixing nut due to the compression spring and telescopic rod's constant compression and extension. Once the fixing nut loosens, the resulting displacement causes the clamping plate to move accordingly, leading to the extension and retraction of the telescopic rod and further compression of the compression spring. This movement of the clamping plate causes the connected sliding plate to slide within the symmetrical grooves inside the rectangular hole. The sliding of the sliding plate, in turn, moves the movable rod, which in turn moves the temporary clamping plate downwards to contact the top surface of the fixing nut for temporary fixation, preventing the fixing nut from completely falling off. Simultaneously, the movement of the clamping plate also causes the contacting detection pin to move. The movement detector detects and reflects the loosening of the fixing nut by observing the movement of the detection pin and promptly provides feedback to the personnel for maintenance. Throughout this process, the loosening detection component ensures the safety of the device, helps maintain its performance, preserves the overall structural stability, and keeps the cold energy storage device within its efficient operating range.

[0010] In a preferred embodiment, the front end of the liquid-cooled energy storage cabinet is movably connected to a cabinet door, the front end of which is fixedly connected to an emergency stop switch and a door handle located to the right of the emergency stop switch. Multiple mounting plates are fixedly connected to the inner wall of the liquid-cooled energy storage cabinet, positioned above battery module mounting plates. A fire extinguishing assembly, including a fire extinguishing device, is installed above one of the mounting plates. A fire extinguishing outlet is fixedly connected to the rear side of the fire extinguishing device, and a fire pipeline is fixedly connected to the front end of the fire extinguishing outlet. Multiple horizontal pipes are fixedly connected to the outer side of the fire pipeline, all located between symmetrical battery module mounting plates. Multiple fire sprinkler heads are fixedly connected to the front end of each horizontal pipe, and a smoke detector is fixedly connected to the bottom end of the fire pipeline.

[0011] Equipped with cabinet doors, emergency stop switches, door handles, mounting plates, and fire extinguishing components, when a fire breaks out in the liquid-cooled energy storage cabinet, the smoke detector first detects smoke and triggers an alarm signal. Then, the fire extinguishing system activates, and the extinguishing agent enters the fire extinguishing pipeline through the fire inlet. It then flows along the fire extinguishing pipeline to various horizontal pipes, reaching multiple fire sprinkler heads at the front end. Finally, the fire sprinkler heads spray the extinguishing agent to extinguish the fire in the area of ​​the liquid-cooled energy storage cabinet where the fire is burning, especially in areas prone to fire and requiring special protection, such as those located between symmetrical battery module mounting plates. The system is designed to suppress the spread of fire, extinguish the fire as much as possible, and reduce the losses caused by the fire. At the same time, if the on-site personnel find the situation to be critical, they can quickly press the emergency stop switch at the front of the cabinet door to stop the operation of related equipment and other operations to ensure on-site safety. The door handle makes it easy to open the cabinet door, which is convenient for further inspection, handling of the fire situation and maintenance. The fire protection system obtains information from the smoke detectors of each battery module and controls the on and off of the fire extinguishing sprinkler heads corresponding to each battery module to achieve fire extinguishing. During the process, the safety of the energy storage device is improved by sensing and extinguishing the fire in each battery module.

[0012] As can be seen from the above, the high-safety liquid-cooled energy storage device provided in this application has the technical effects of fixing the battery module to give the energy storage device strong strength and vibration resistance; using four lifting lugs fixed on the top of the liquid-cooled energy storage cabinet to facilitate hoisting and improve transportation reliability; and connecting the fixed base to the ground with screws to maintain the stability of the energy storage device and give it strong environmental adaptability.

[0024] Working principle: The liquid-cooled energy storage cabinet 1 supports various equipment and energy storage battery modules. Lifting lugs 7 are provided on both sides of the vertical frame 8 and the horizontal frame 6 for connecting hooks to complete lifting operations. The liquid-cooled energy storage cabinet 1 has a fixed base 4 for easy and secure fixing to various ground surfaces. The fixing nut 15 is used to tightly connect the battery module 12 to the battery module fixing plate 11, improving equipment reliability. When the fixing nut 15 loosens, the clamping plate 1401, originally in a normally fixed state, maintains a certain degree of compression and extension with the compression spring 1403 and the telescopic rod 1402 to maintain the relative position stability of the clamping plate 1401 relative to the fixing nut 15. Once the fixing nut 15 loosens, the resulting displacement will cause the clamping plate 1401 to... The corresponding movement causes the telescopic rod 1402 to extend and retract, and the compression spring 1403 to compress further. The movement of the clamping plate 1401 causes the sliding plate 1405 connected to it to slide in the symmetrical groove inside the rectangular hole. The sliding of the sliding plate 1405 causes the movable rod 1406 to move. The movable rod 1406 then causes the temporary pressing plate 1404 to move downward and contact the top surface of the fixing nut 15 for temporary fixation, preventing the fixing nut 15 from completely falling off. At the same time, the movement of the clamping plate 1401 also causes the detection needle 1408 in contact with it to move. The movement detector 1409 detects and reflects the loosening of the fixing nut 15 by the movement change of the detection needle 1408, and promptly reports it to the staff for maintenance.

[0025] When the liquid-cooled energy storage cabinet 1 catches fire, the smoke detector 1006 will first detect the smoke and trigger an alarm signal. Then, the fire extinguishing device 1001 will activate, and the extinguishing agent will enter the fire extinguishing pipeline 1003 through the fire extinguishing inlet 1002. It will then flow along the fire extinguishing pipeline 1003 to various horizontal pipes 1005. The extinguishing agent will then travel along the horizontal pipes 1005 to the multiple fire sprinkler heads 1004 at the front end. Finally, the fire sprinkler heads 1004 will spray the extinguishing agent to extinguish the fire in the area of ​​the liquid-cooled energy storage cabinet 1, especially targeting the symmetrically located battery module mounting plates. The system protects vulnerable areas such as those between 11 and 2, which are prone to fire and require special protection, in order to suppress the spread of fire, extinguish the fire as much as possible, and reduce the losses caused by the fire. At the same time, if the on-site personnel find the situation to be critical, they can quickly press the emergency stop switch 3 at the front of the cabinet door 2 to stop the operation of related equipment and other operations to ensure on-site safety. The door handle 5 makes it easy to open the cabinet door 2, which is convenient for further inspection, handling of the fire situation and maintenance. The fire protection system obtains the information of the smoke detector of each battery module 12 and controls the on and off of the fire extinguishing sprinkler head 1004 corresponding to each battery module 12 to achieve fire extinguishing.

The substitutions may be replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this application should all be covered within the scope of protection of this application.
