Description

Technical Field

[0001] This utility model relates to the field of new energy storage cabinet technology, and in particular to a safety monitoring device for new energy storage cabinets. Background Technology

[0002] The safety monitoring device for new energy storage cabinets is mainly used to ensure the safety of the storage cabinets. Especially when using high-energy-density battery technologies such as lithium batteries, this device can monitor the working status of the storage cabinets in real time and prevent potential safety hazards, such as overheating, short circuits, and battery leaks.

[0003] Battery thermal runaway is usually caused by internal short circuits, overcharging, or external high temperature factors. In common new energy storage cabinets, once thermal runaway occurs, the battery temperature will rise sharply, causing the electrolyte to decompose and generate a large amount of heat and flammable gas. The thermal runaway of a single battery module may quickly spread to adjacent modules, eventually leading to the destruction of the entire energy storage device.

[0004] Therefore, in response to the problem that combustible and toxic gases cannot be discharged or isolated in time in the above-mentioned new energy storage cabinets, they will accumulate in the storage cabinets and spread to adjacent modules, affecting the entire energy storage device, a new type of safety monitoring device for new energy storage cabinets is designed. Utility Model Content

[0005] In order to overcome the common problem that combustible and toxic gases cannot be discharged or isolated in time in common new energy storage cabinets, they will accumulate in the storage cabinet, spread to adjacent modules, and affect the entire energy storage device.

[0006] The technical solution of this utility model is as follows: a safety monitoring device for a new energy storage cabinet, including a cabinet body; and a battery mounting plate installed on the inner wall of the cabinet body. The surface of the battery mounting plate is provided with a grid sealing groove. An electric slide rail is installed on the left and right inner walls of the cabinet body respectively. A sliding block is slidably connected to the surface of the electric slide rail. A connecting plate is connected between the two sliding blocks. The moving component includes an electric slide rail II, a connecting module, and an installation module, which are set at the lower end of the connecting plate. The electric slide rail II is used to drive the installation module to move. The sealing component includes an electric push rod and a sealing module installed on the outer side of the installation module. The electric push rod is used to push the sealing module to move. The exhaust component includes a harmful gas collection box, a conveying module, and a transport module, which are set on the top surface inside the cabinet body. The harmful gas collection box is used to store and collect leaked gas from the battery. The transport module provides path support for the leaked gas. The conveying module is used to drive the leaked gas to flow into the collection module.

[0007] Preferably, upon receiving an alarm signal, the electric slide rail one installed on the left and right inner walls of the cabinet is activated first, driving the sliding block one on it to slide vertically. The entire moving assembly is then adjusted to the height of the target battery via the connecting plate. Subsequently, the electric slide rail two located at the lower end of the connecting plate starts working, driving the sliding block two to move laterally, thereby causing the L-shaped plate connected to it to move horizontally, so that the sealing assembly is accurately aligned with the faulty battery cell. Next, the electric push rod is activated, pushing the sealing module connected to its front end to move forward, completely enclosing the abnormal battery module and forming a closed, airtight space, effectively preventing harmful gases from spreading outward. At the same time, the conveying module is activated, and the leaked gas in the chamber is pumped to the harmful gas collection box at the top for centralized treatment through the conveying module connected to the sealing module. Meanwhile, inert gases such as nitrogen can be selectively injected into the sealing module to dilute the concentration of flammable gases and suppress combustion.

[0008] Preferably, the electric slide rail is used to drive the sliding block to move up and down. The sliding block acts as a bridge between the electric slide rail and the connecting plate. The sliding block changes the position of the connecting plate by sliding itself.

[0009] Preferably, the connecting module includes a sliding block two that is slidably connected to the outer side of the electric slide rail two, and the sliding block two acts as a bridge between the electric slide rail two and the mounting module.

[0010] Preferably, the mounting module includes an L-shaped plate disposed on the lower end face of the sliding block 2, the L-shaped plate providing mounting space and mounting fulcrum for the electric push rod.

[0011] Preferably, the sealing module includes an isolation chamber connected to the output end of the electric actuator, which is used to isolate the battery in the event of thermal runaway, gas leakage, or abnormal temperature rise.

[0012] Preferably, the delivery module includes an air pump located on the lower end face of the hazardous gas collection box, which collects hazardous gases while providing inert gas. The air pump can discharge hazardous air or inject inert gas into the isolation chamber.

[0013] Preferably, the transport module includes a telescopic tube disposed at the output end of the air pump, with the end of the telescopic tube away from the air pump connected to the outer surface of the isolation chamber, and the telescopic tube providing a passage for harmful gases and inert gases to enter the isolation chamber.

[0014] Preferably, a gas sensor is installed on the upper surface of the isolation chamber. The gas sensor is used to detect batteries that have experienced thermal runaway, gas leakage, or abnormal temperature rise.

[0015] The beneficial effects of this utility model are:

[0016] 1. Equipped with a movable isolation chamber, combined with an electric push rod, it enables rapid sealing of abnormal batteries, effectively preventing safety hazards such as thermal runaway and gas leakage, and improving the safety of the device.

[0017] 2. Integrates a hazardous gas collection box, air pump, and telescopic pipe to enable immediate extraction, storage, and inert gas replacement of leaked gases, significantly reducing the risk of combustion and minimizing secondary accidents. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment of a new energy storage cabinet safety monitoring device, including a cabinet 1; it also includes a battery mounting plate 2 installed on the inner wall of the cabinet 1, the surface of the battery mounting plate 2 having a grid sealing groove 4, an electric slide rail 6 installed on the left and right inner walls of the cabinet 1 respectively, a sliding block 7 slidably connected to the surface of the electric slide rail 6, and a connecting plate 8 connecting the two sliding blocks 7, a moving component including an electric slide rail 9 disposed at the lower end of the connecting plate 8, a connecting module and an installation module, the electric slide rail 9 being used to drive the installation module to move, a sealing component including an electric push rod 12 installed on the outer side of the installation module and a sealing module, the electric push rod 12 being used to push the sealing module to move, an exhaust component including a harmful gas collection box 15 disposed on the top surface inside the cabinet 1, a conveying module and a transport module, the harmful gas collection box 15 being used to store and collect leaked gas from the battery, the transport module providing path support for the leaked gas, the conveying module being used to drive the leaked gas to flow into the collection module, the electric slide rail 6 being used to drive the sliding block 7 to move up and down, the sliding block 7 acting as The bridge between the electric slide rail 16 and the connecting plate 8 is formed by the sliding block 7 changing the position of the connecting plate 8 through its own sliding. After receiving the alarm signal, the electric slide rail 16 installed on the left and right inner walls of the cabinet 1 is activated first, driving the sliding block 7 on it to slide vertically. The entire moving assembly is then adjusted to the height of the target battery through the connecting plate 8. Subsequently, the electric slide rail 29 located at the lower end of the connecting plate 8 starts to work, driving the sliding block 20 to move laterally, thereby driving the L-shaped plate 11 connected to it to achieve horizontal displacement, so that the sealing assembly is accurately aligned with the faulty battery cell. Next, the electric push rod 12 is activated, pushing the sealing module connected to its front end to move forward, completely enclosing the abnormal battery module and forming a closed airtight space, effectively preventing harmful gases from spreading outward. At the same time, the conveying module is activated, and the leaked gas in the chamber is pumped to the harmful gas collection box 15 at the top for centralized treatment through the conveying module connected to the sealing module. At the same time, inert gases such as nitrogen can be selectively injected into the sealing module to dilute the concentration of flammable gases and suppress the occurrence of combustion.

[0026] Please see Figure 2 , Figure 4 and Figure 5In this embodiment, the connection module includes a sliding block 10 slidably connected to the outer side of the electric slide rail 9. The sliding block 10 acts as a bridge between the electric slide rail 9 and the installation module. The electric slide rail 9 drives the sliding block 10 to slide precisely in the horizontal direction to achieve lateral positioning. The sliding block 10 is a transitional connection component that transmits motion power. The installation module includes an L-shaped plate 11 set on the lower end face of the sliding block 10. The L-shaped plate 11 provides installation space and mounting fulcrum for the electric push rod 12. The L-shaped plate 11 provides structural support and position guidance for the electric push rod 12. The electric push rod 12 pushes the isolation chamber 13 forward or retracts through telescopic movement to control the isolation chamber 13 and complete the covering and sealing of the abnormal battery. The sealing module includes an isolation chamber 13 connected to the output end of the electric push rod 12. The isolation chamber 13 is used to isolate the battery that has experienced thermal runaway, gas leakage, or abnormal temperature rise. The isolation chamber 13 is pushed to the target position by the electric push rod 12 to form a closed space, isolating the abnormal battery module and preventing the spread of danger.

[0027] Please see Figures 2-5 In this embodiment, the delivery module includes an air pump 16 disposed on the lower end face of the hazardous gas collection box 15. The hazardous gas collection box 15 is used to collect hazardous gases and simultaneously provide inert gases. The air pump 16 can discharge hazardous air or inject inert gases into the isolation chamber 13. (The hazardous gas collection box 15 is used to collect hazardous gases leaking from inside the energy storage cabinet and to store a certain amount of inert gas, such as nitrogen. It not only serves as a safe storage container for hazardous gases but also provides a necessary source of inert gas for suppressing combustion.) The transport module includes a telescopic pipe 14 disposed at the output end of the air pump 16. The end of the telescopic pipe 14 away from the air pump 16 is connected to the outer surface of the isolation chamber 13. The telescopic pipe 14 provides a channel for hazardous gases and inert gases to enter the isolation chamber 13. (The telescopic pipe 14 is designed to adapt to the isolation chamber 13.) The change in position provides a flexible and reliable channel to ensure that both the discharge of harmful gases and the injection of inert gases can proceed smoothly. A gas sensor 17 is installed on the upper surface of the isolation chamber 13. The gas sensor 17 is used to detect batteries that have experienced thermal runaway, gas leakage, or abnormal temperature rise (the detection and analysis of gas components by the gas sensor 17 is a conventional technology and will not be described in detail in this application). The gas sensor 17 monitors the gas composition and concentration around each battery in real time. Once it detects that the dangerous gas exceeds the standard or the temperature rises abnormally, it will immediately send a signal so that the corresponding mechanism can be taken in time. The front end of the battery mounting plate 2 has multiple mounting slots 3. The battery body 5 is installed inside the mounting slot 3. The mounting slot 3 is used to accommodate and position a single battery body 5 to ensure its stability in the energy storage cabinet.

[0028] During operation, the gas sensor 17 installed on the upper surface of the isolation chamber 13 continuously monitors the battery's operating status. When a battery module experiences a sudden temperature rise, gas leakage, or abnormal temperature increase, the sensor feeds back a signal to the control mechanism, which controls the movement of the electric slide rail 6 installed on the left and right inner walls of the cabinet 1. The sliding block 7 slides up and down along the electric slide rail 6, moving the connecting plate 8 to the height of the target battery. Then, the electric slide rail 9 installed at the lower end of the connecting plate 8 drives the sliding block 10 to move laterally. The sliding block 10 moves the L-shaped plate 11 connected to it horizontally, so that the sealing assembly is precisely aligned with the faulty battery. The electric push rod 12 is activated, pushing the isolation chamber 13 installed at its output end to move forward. The isolation chamber 13 encloses the abnormal battery module, forming an airtight space to prevent the spread of harmful gases. The air pump 16 is activated, and the harmful gases in the isolation chamber 13 are pumped to the harmful gas collection box 15 through the telescopic pipe 14. The harmful gas collection box 15 can selectively inject inert gases such as nitrogen into the isolation chamber 13 to suppress the risk of combustion and improve safety.

[0029] Through the above steps, the isolation chamber 13 is pushed by the electric push rod 12 to quickly cover the battery unit that has experienced thermal runaway, gas leakage, or abnormal temperature rise, forming a local sealed space. This effectively curbs the diffusion of harmful gases and the spread of heat. The gas treatment structure, which integrates the harmful gas collection box 15, the air pump 16, and the telescopic pipe 14, enables real-time extraction and safe disposal of leaked gases. This solves the common problem in new energy storage cabinets where combustible and toxic gases cannot be discharged or isolated in time, and will accumulate in the storage cabinet, spread to adjacent modules, and affect the entire energy storage device.
