Description

Technical Field

[0001] This utility model relates to the field of pipeline leakage prevention technology, specifically to a leakage prevention structure for cooling pipelines in semi-solid energy storage systems. Background Technology

[0002] Cooling pipes in semi-solid-state energy storage systems are the core fluid channel structures responsible for transferring cooling media and removing heat from the system. They are key sub-components ensuring the safe, efficient, and long-life operation of the energy storage system. Essentially, they address the problem of heat accumulation during charging and discharging of semi-solid-state batteries through media flow and heat exchange, preventing risks such as performance degradation and thermal runaway due to overheating. When using cooling pipes, leak-proof structures are necessary to prevent pipe leaks and to detect leaks.

[0003] The existing semi-solid energy storage system's cooling pipeline leak-proof structure uses internal threaded rings and threaded sleeves at both ends of the cooling pipeline to increase the connection's strength. At the same time, a sealing ring is adhered to the inner wall of the threaded sleeve with strong adhesive to prevent leakage. Meanwhile, a pressure sensor detects whether the cooling pipeline is leaking. When the semi-solid energy storage system's cooling pipeline is running, the pressure sensor captures abnormal fluctuations in the pressure signal in real time. Under normal operating conditions, the pressure fluctuation range is usually within a certain range. If the pressure suddenly drops sharply or continues to fluctuate abnormally, it may indicate that the sealing structure has failed (such as aging of the sealing ring or loosening of the threads), thereby triggering an alarm to remind the staff.

[0004] The leak-proof structure of the cooling pipes in existing semi-solid energy storage systems relies solely on the friction of the threaded joints to prevent loosening. However, semi-solid energy storage systems experience continuous vibration, which gradually diminishes the preload between the threads, causing them to loosen slightly. At this point, the sealing rings adhered by the strong adhesive lose their compressive sealing force, directly forming a leakage channel. In addition, the sealing rings are fixed to the inner wall of the threaded sleeve by the strong adhesive, but the energy storage cooling medium will slowly corrode the strong adhesive, and high and low temperature cycles will accelerate the aging of the adhesive layer and hardening of the sealing rings, ultimately leading to the sealing rings falling off or the sealing gaps increasing. More importantly, traditional solutions lack backup seals. Once the seals fail, the cooling medium leaks directly from the threaded gaps. This results in the existing semi-solid energy storage system's leak-proof structure for cooling pipes having poor vibration resistance, making it prone to loosening due to vibration, and also having low fault tolerance. Furthermore, the pressure sensors in the existing semi-solid energy storage system's leak-proof structure rely on electronic components and the power supply system. However, interference sources in the energy storage system can interfere with the electronic components and power supply system of the pressure sensors. Consequently, once the pressure sensors fail, the existing semi-solid energy storage system's leak-proof structure for cooling pipes loses its ability to detect leaks in the cooling pipes, thus making the device less practical. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a leak-proof structure for the cooling pipeline of a semi-solid energy storage system. This structure increases the device's resistance to vibration and loosening, thereby preventing leakage caused by vibration. It also prevents coolant leakage by incorporating rubber pads, thus increasing the device's fault tolerance. Furthermore, it provides overpressure and leakage alarms when the pressure sensor is interfered with or fails, thereby increasing the device's practicality.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The leak-proof structure of the cooling pipeline of the semi-solid energy storage system includes a cooling pipeline 1, a connecting pipe fixedly connected to the top of the cooling pipeline 1, a control device fixedly connected to the top of the connecting pipe, an alarm fixedly connected to one side of the control device, a pressure sensor fixedly connected to the cooling pipeline 1, a pressure relief pipe fixedly connected to one side of the cooling pipeline 1, a solenoid valve 2 fixedly connected to the pressure relief pipe, a solenoid valve 1 fixedly connected to the cooling pipeline 1, a trigger switch 1 installed inside the connecting pipe, a spring fixedly connected to the inside of the connecting pipe, a sealing sliding block fixedly connected to one side of the spring, a connecting bracket fixedly connected to the inside of the connecting pipe, a trigger button installed on the top of the connecting bracket, and a connecting assembly located on the outside of the cooling pipeline 1.

[0008] In one optional embodiment, a through hole is provided on the connecting pipe, and the sealing sliding block is slidably connected to the inside of the connecting pipe through the through hole.

[0009] In one alternative embodiment, rubber pads to enhance sealing are provided on both sides of the sealing sliding block.

[0010] In one optional embodiment, the sealing sliding block is provided with protruding posts on both sides to facilitate triggering the trigger button and trigger switch.

[0011] In one optional embodiment, the connecting assembly includes a threaded sleeve fixedly connected to the outside of a cooling pipe, a flange fixedly connected to the outside of the threaded sleeve, a rubber gasket fixedly connected to the inside of the threaded sleeve, a threaded pipe threadedly connected to the inside of the threaded sleeve, a cooling pipe fixedly connected to one side of the threaded pipe, a flange fixedly connected to the outside of the cooling pipe, a rubber gasket fixedly connected to one side of the flange, a bolt slidably connected to the inside of the flange, a gasket slidably connected to the outside of the bolt, a nut threadedly connected to the outside of the bolt, and a nut threadedly connected to the outside of the bolt.

[0012] In one optional embodiment, a through hole 2 is provided on flange 2 and rubber gasket 1, and bolts pass through the through hole 2 through flange 2 and rubber gasket 1.

[0013] In one optional embodiment, the second cooling pipe has a through hole three, and the first cooling pipe is slidably connected to the inside of the second cooling pipe through the through hole three.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The user connects cooling pipe two to the threaded sleeve by rotating the cooling pipe two, completing the initial alignment and connection of cooling pipe one and cooling pipe two. Then, the user inserts bolts into flange two, rubber gasket one, and flange one, and then slides a gasket into the bolt. Next, the user rotates nut one to thread it onto the bolt, and then rotates nut two to thread it onto the bolt, thus connecting flange two to flange one. By setting up double mechanical constraints, the device's vibration resistance and anti-loosening ability are increased, thereby avoiding leakage caused by vibration. The setting of rubber gasket one and rubber gasket two increases the device's sealing performance. When rubber gasket two fails and leaks, rubber gasket one can prevent coolant leakage, thereby increasing the device's fault tolerance.

[0016] 2. When the pressure sensor malfunctions due to interference, a leak in cooling pipe 1 causes a pressure drop. The sealing sliding block moves downwards under the force of the spring. When the pressure drop reaches a certain threshold, the sealing sliding block touches the trigger button. The trigger button transmits an electrical signal to the control device, which then activates the alarm to alert the operator. Simultaneously, the control device activates solenoid valve 1 to close cooling pipe 1, preventing coolant leakage. When cooling pipe 1 becomes blocked, causing a continuous pressure increase, the pressure pushes the sealing sliding block upwards, compressing the spring. When the pressure reaches a certain threshold, the sealing sliding block touches trigger switch 1, which transmits an electrical signal to the control device, activating the alarm. Simultaneously, the control device opens solenoid valve 2, allowing coolant in cooling pipe 1 to drain through the pressure relief pipe, preventing damage to cooling pipes 1 and 2 due to excessive pressure and thus increasing the device's practicality.

[0027] Against the backdrop of the global energy structure transitioning towards renewable energy, the installed capacity of clean energy sources such as wind and solar power continues to climb. However, these energy sources are significantly affected by natural conditions, exhibiting strong intermittency and fluctuations in output power, posing a significant challenge to the stable operation of the power grid. Energy storage systems, as core equipment for mitigating the fluctuations in renewable energy and ensuring the balance between power grid supply and demand, directly determine the efficiency of renewable energy absorption through their performance and safety. Traditional liquid energy storage systems (such as liquid lithium-ion battery energy storage) possess high energy density, but their electrolytes are prone to leakage, easily leading to fires and explosions under high temperatures or mechanical impacts. While all-solid-state energy storage systems address the leakage risk through solid electrolytes, they face problems such as low ionic conductivity, insufficient charge and discharge efficiency, and high costs. Against this backdrop, semi-solid-state energy storage systems have become a research hotspot in the industry due to their "balance advantage"—they use gel-state or semi-solid-state electrolytes containing a small amount of liquid electrolyte, retaining the high ion conduction efficiency of liquid systems while significantly reducing the probability of electrolyte leakage, simultaneously balancing energy density and safety. They have been widely applied in large-scale energy storage power stations, new energy vehicle power batteries, and portable energy storage devices.

[0028] From a system composition perspective, a semi-solid-state energy storage system is not a single component, but a complex system composed of multiple modules working in tandem. It mainly includes four core parts: battery modules, a battery management system (BMS), a thermal management system, and a protective casing. The battery module is the core of energy storage and release, consisting of dozens to hundreds of semi-solid-state battery cells connected in series or parallel. Each cell contains a positive electrode (such as ternary materials or lithium iron phosphate), a negative electrode (such as graphite or silicon-based materials), a semi-solid electrolyte, and a separator. The semi-solid electrolyte fills the space between the positive and negative electrodes, enabling efficient lithium-ion transport and blocking electrolyte flow through its viscous structure, thus avoiding the leakage and short-circuit risks common in liquid systems. The BMS acts as the "brain," monitoring parameters such as voltage, current, and individual cell temperature of the battery modules in real time, precisely controlling the charging and discharging process to prevent battery degradation or thermal runaway caused by overcharging or over-discharging. Simultaneously, the BMS works in conjunction with the thermal management system; when the battery temperature exceeds a threshold (typically 45°C), the cooling system is immediately activated to ensure the system operates within its optimal range of 25-40°C. The protective shell is made of high-strength engineering plastics (such as PA66+glass fiber) or lightweight alloys (such as aluminum alloy 6061), and has waterproof, dustproof and impact-resistant properties. It can adapt to the harsh environment of outdoor power stations or the vibration conditions of vehicle-mounted scenarios, and provide physical protection for internal components.

[0029] Throughout the entire system operation, the thermal management system plays a crucial supporting role in ensuring safety and lifespan. Although semi-solid-state energy storage systems are more resistant to high temperatures than liquid systems, as capacity and power increase, polarization heat and chemical reaction heat continuously accumulate during battery charging and discharging. If this heat cannot be dissipated in time, it will lead to uneven battery temperature—local hotspot temperatures may exceed 60°C. This not only accelerates the aging of electrode materials (such as the collapse of the positive electrode material structure and the rupture of the negative electrode SEI film), shortening the battery cycle life by more than 30%, but may also trigger the decomposition of the semi-solid electrolyte, releasing flammable gases and triggering a thermal runaway chain reaction. Therefore, the thermal management system needs to form a closed loop through components such as cooling pipes, cooling medium, circulating pumps, and radiators to efficiently remove the heat generated by the battery. As the "blood vessels" of heat transfer, the sealing of the cooling pipes directly determines the thermal management effect: if the pipes leak, the loss of cooling medium will cause a sharp drop in heat dissipation efficiency and lead to high system temperature. At the same time, if the cooling medium (such as ethylene glycol aqueous solution or insulating mineral oil) seeps into the battery module, it may corrode the electrodes or damage the electrolyte structure, or even cause a short circuit. Therefore, the leak-proof structure design of the cooling pipes has become one of the core technologies for the reliable operation of semi-solid-state energy storage systems.

[0030] Specifically, the cooling piping of a semi-solid-state energy storage system is not a simple pipe, but a transmission network customized according to the system power, application scenario, and characteristics of the cooling medium. Its core function is to achieve efficient and stable delivery of the cooling medium, while adapting to temperature changes and vibration environments within the system. Functionally, the cooling piping typically consists of a main pipe, branch pipes, connectors, valves, and auxiliary fasteners: the main pipe connects the circulation pump and radiator, delivering a large flow of cooling medium; branch pipes extend deep into the battery module, using serpentine or parallel pipe layouts to closely approach the battery cells, maximizing the heat exchange area—for example, in automotive semi-solid-state battery packs, branch pipes are tightly fitted to the sides or bottom of the battery cells, transferring heat to the cooling medium through forced convection; valves are used to control the on / off state of the cooling circuit and regulate the flow rate. In the event of a partial system failure, the corresponding valve can be closed for maintenance, preventing a complete system shutdown.

[0031] The design of cooling pipelines must be closely matched to the characteristics of the cooling medium, as different media have significantly different requirements for pipeline materials and sealing. Currently, there are three main types of cooling media commonly used in semi-solid energy storage systems: The first type is ethylene glycol aqueous solution, which has the advantages of a low freezing point (down to -40℃) and high specific heat capacity, making it suitable for low-temperature environments and high-power heat dissipation. However, it is corrosive and conductive; leaks can easily cause battery short circuits, therefore the pipelines must have strong corrosion resistance and absolute sealing. The second type is insulating mineral oil (such as paraffin-based lubricating oil), which has good insulation and resistance to high and low temperatures; even if leaks occur, they will not cause short circuits. However, its high viscosity requires stricter control of flow resistance in the pipelines, necessitating the use of large-diameter pipelines or low-friction inner wall designs. The third type is fluorinated liquid. (e.g., perfluoropolyether), which is resistant to high temperatures (boiling point > 200℃), has strong chemical stability, and is insulating and non-flammable, is suitable for high power density systems (such as containerized systems in energy storage power stations), but is more expensive and has strict requirements for the compatibility of pipeline materials—fluoroplastics (such as PTFE) or modified nylon pipelines must be used to avoid chemical reactions between the medium and the pipe wall. Based on the key role of cooling pipelines, their sealing performance directly determines the reliable operation of semi-solid energy storage systems, while leakage risks are mainly concentrated at joint connection interfaces, pipeline bodies (such as bends, uneven wall thicknesses), and stress concentration points caused by installation and fixing.

[0032] Please see Figures 1-5This utility model provides an embodiment of a leak-proof structure for the cooling pipeline of a semi-solid energy storage system, including a cooling pipeline 1, a connecting pipe 2 fixedly connected to the top of the cooling pipeline 1, a control device 301 fixedly connected to the top of the connecting pipe 2, an alarm 303 fixedly connected to one side of the control device 301, a pressure sensor 302 fixedly connected to the cooling pipeline 1, a pressure relief pipe 304 fixedly connected to one side of the cooling pipeline 1, a solenoid valve 306 fixedly connected to the pressure relief pipe 304, and a valve fixedly connected to the cooling pipeline 1. The components include: a solenoid valve 305 on cooling pipe 1, a trigger switch 307 installed inside connecting pipe 2, a spring 308 fixedly connected inside connecting pipe 2, a sealing sliding block 309 fixedly connected to one side of spring 308, a connecting bracket 310 fixedly connected inside connecting pipe 2, a trigger button 311 installed on top of connecting bracket 310, and a connecting assembly located outside cooling pipe 1. When pressure sensor 302 is interfered with and fails, leakage in cooling pipe 1 causes a drop in pressure within cooling pipe 1, triggering the sealing sliding block 309 to... Under the force of spring 308, the sealing sliding block 309 moves downward. When the pressure drops to a certain threshold, the sealing sliding block 309 touches the trigger button 311. The trigger button 311 transmits an electrical signal to the control device 301, thereby activating the alarm 303 to alert the staff. At the same time, the control device 301 activates solenoid valve 305 to close the cooling pipe 1, thus preventing the coolant in the cooling pipe 1 from flowing out. When the cooling pipe 1 is blocked, causing the pressure to rise continuously, the pressure pushes the sealing sliding block. As pressure continues to rise, spring 308 is compressed. When the pressure reaches a certain threshold, sealing sliding block 309 touches trigger switch 307. Trigger switch 307 transmits an electrical signal to control device 301, causing control device 301 to activate alarm 303. At the same time, control device 301 opens solenoid valve 306, allowing coolant in cooling pipe 1 to be discharged from pressure relief pipe 304. This prevents cooling pipe 1 and cooling pipe 2 410 from being damaged due to excessive pressure, thus increasing the practicality of the device.

[0033] In a preferred embodiment of this utility model, a through hole is provided on the connecting pipe 2, and the sealing sliding block 309 is slidably connected to the inside of the connecting pipe 2 through the through hole. This facilitates the lifting and lowering movement of the sealing sliding block 309 inside the connecting pipe 2, which in turn facilitates the sealing sliding block 309 to trigger the trigger switch 307 or the trigger button 311, thereby helping to remind the staff of cooling pipe leakage or overpressure.

[0034] In a preferred embodiment of this utility model, rubber pads are provided on both sides of the sealing sliding block 309 to increase the sealing performance. The machining accuracy of the inner wall of the connecting pipe 2 and the dimensional error of the sealing sliding block 309 may lead to uneven fit between the two. By compensating for the machining error with rubber pads, the sealing sliding block 309 can be prevented from sliding and jamming, thereby ensuring the timely triggering of the trigger button 311 and the trigger switch 307.

[0035] In a preferred embodiment of this utility model, the sealing sliding block 309 is provided with protruding posts on both sides to facilitate triggering the trigger button 311 and the trigger switch 307. When the leakage pressure of the cooling pipe 1 decreases, the elastic force of the spring 308 pushes the sealing sliding block 309 to move horizontally toward the trigger button 311. When the cooling pipe 1 is blocked and pressurized, the sealing sliding block 309 is squeezed by the pressure to move horizontally toward the switch 307. This facilitates the triggering of the trigger switch 307 or the trigger button 311 by the protruding posts when the cooling pipe 1 is over-pressurized or leaking, thus reminding the user.

[0036] Please see Figure 5 In this embodiment, the connecting assembly includes a threaded sleeve 401 fixedly connected to the outside of the cooling pipe 1, a flange 402 fixedly connected to the outside of the threaded sleeve 401, a rubber gasket 411 fixedly connected to the inside of the threaded sleeve 401, a threaded pipe 409 threadedly connected to the inside of the threaded sleeve 401, a cooling pipe 410 fixedly connected to one side of the threaded pipe 409, a flange 404 fixedly connected to the outside of the cooling pipe 410, a rubber gasket 403 fixedly connected to one side of the flange 404, a bolt 405 slidably connected to the inside of the flange 402, a washer 406 slidably connected to the outside of the bolt 405, a nut 407 threadedly connected to the outside of the bolt 405, and a nut 408 threadedly connected to the outside of the bolt 405. The user completes the connection by rotating the cooling pipe 410 to thread it into the inside of the threaded sleeve 401. The initial alignment and connection of cooling pipe 1 and cooling pipe 2 410 are then performed. The user inserts bolt 405 into flange 2 404, rubber gasket 1 403 and flange 1 402, then slides gasket 406 onto bolt 405. Nut 1 407 is then threaded onto bolt 405, and nut 2 408 is then threaded onto bolt 405, thus connecting flange 2 404 and flange 1 402. This double mechanical constraint enhances the device's vibration resistance and prevents loosening, thus avoiding leakage caused by vibration. The use of rubber gasket 1 403 and rubber gasket 2 411 increases the device's sealing performance. When rubber gasket 2 411 fails and leaks, rubber gasket 1 403 prevents coolant leakage, thereby increasing the device's fault tolerance.

[0037] In a preferred embodiment of this utility model, a through hole 2 is provided on flange 2 404 and rubber gasket 1 403. Bolt 405 passes through flange 2 404 and rubber gasket 1 403 through the through hole 2, which facilitates connecting flange 2 404, rubber gasket 1 403 and flange 1 402 by bolt 405 and gasket 406.

[0038] In a preferred embodiment of this utility model, cooling pipe 2 410 is provided with through hole 3, and cooling pipe 1 is slidably connected to the inside of cooling pipe 2 410 through through hole 3, which facilitates the connection between cooling pipe 1 and cooling pipe 2 410, thereby facilitating the flow of coolant in cooling pipe 1 and cooling pipe 2 410.

[0039] During operation, the user connects the second cooling pipe 410 to the threaded sleeve 401 by rotating the second cooling pipe 410, completing the initial alignment and connection between the first cooling pipe 1 and the second cooling pipe 410. Then, the user inserts the bolt 405 through the flange 404, rubber gasket 403, and flange 402, slides the washer 406 onto the bolt 405, and then rotates the nut 407 to thread it onto the bolt 405. Finally, the user rotates the second nut 408 to thread it onto the bolt 405. 5. This connects flange 2 404 to flange 1 402. The double mechanical constraint enhances the device's vibration resistance and prevents loosening, thus avoiding leakage caused by vibration. The use of rubber gasket 1 403 and rubber gasket 2 411 improves the device's sealing. When rubber gasket 2 411 fails and leaks, rubber gasket 1 403 prevents coolant leakage, increasing the device's fault tolerance. When pressure sensor 302 malfunctions due to interference, leakage in cooling pipe 1 causes leakage in cooling pipe 1... When the pressure inside pipe 1 decreases, the sealing sliding block 309 moves downward under the force of the spring 308. When the pressure drop reaches a certain threshold, the sealing sliding block 309 touches the trigger button 311. The trigger button 311 transmits an electrical signal to the control device 301, thereby activating the alarm 303 to alert the staff. At the same time, the control device 301 activates the solenoid valve 305 to close the cooling pipe 1, thus preventing the coolant in the cooling pipe 1 from flowing out. When the cooling pipe 1 is blocked, causing the pressure to rise continuously... The pressure pushes the sealing sliding block 309 to rise continuously, compressing the spring 308. When the pressure reaches a certain threshold, the sealing sliding block 309 touches the trigger switch 307. The trigger switch 307 transmits an electrical signal to the control device 301, thereby activating the alarm 303. At the same time, the control device 301 opens the solenoid valve 306, allowing the coolant in the cooling pipe 1 to be discharged from the pressure relief pipe 304. This prevents the cooling pipe 1 and the cooling pipe 2 410 from being damaged due to excessive pressure, thus increasing the practicality of the device.

[0041] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
