Description

Technical Field

[0001] This invention relates to the field of lithium battery safety storage cabinet technology, specifically a fireproof lithium battery storage cabinet with intelligent fire monitoring. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They are characterized by high energy density, long cycle life, low self-discharge rate, and no memory effect. They are used in new energy vehicles, energy storage systems, and industrial machinery. They can stably output electrical energy under different operating conditions and are a core component for achieving energy conservation, emission reduction, and energy structure upgrading in modern energy systems.

[0003] The fireproof lithium battery storage cabinet with intelligent fire monitoring is a special device for the safe storage of lithium batteries. It includes an explosion-proof cabinet, a fireproof and heat-insulating layer, multi-parameter monitoring components and ventilation and heat dissipation mechanisms. It is used in lithium battery production workshops, energy storage power stations, logistics warehouses and emergency repair scenarios. It can effectively isolate the risks of lithium battery storage, provide real-time warnings of safety hazards, and prevent the spread of fire. It is a key device for improving the safety level of centralized management of lithium batteries.

[0004] Currently available intelligent fireproof lithium battery storage cabinets consist of an integrated cabinet body, sensors, and fire extinguishers. During use, the cabinet's own fireproof structure provides basic protection. To enhance the safety of the internal environment, existing technologies use uniform smoke or temperature detectors installed at the top of the cabinet for fire monitoring. To prevent a chain reaction caused by thermal runaway of a single battery, existing technologies use physical partitions for zoning and configure a uniform fire extinguishing agent spraying system. However, due to the use of partitions, the overall ventilation is uneven, and harmful gases cannot be discharged in time when a battery fails, spreading to different layers within the cabinet and reducing the cabinet's safety protection effectiveness and reliability.

[0017] This invention provides a fireproof lithium battery storage cabinet for intelligent fire monitoring. It has the following beneficial effects:

[0018] 1. This invention starts servo motor one, which causes gear one and rack one to drive the slide plate and baffle to descend synchronously, closing all ventilation slots. Then, the electromagnet corresponding to the faulty layer is energized to attract the iron block on the baffle of that layer.

[0020] 3. In this invention, when storing batteries, the batteries are placed between two clamping plates, and then the lead screw is rotated to make the slider move horizontally.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 2 , Figure 4 and Figure 5This invention provides a fireproof lithium battery storage cabinet with intelligent fire monitoring, including a cabinet body 1. The cabinet body 1 provides explosion-proof and fireproof isolation protection for lithium battery storage. An opening and closing mechanism 2 is provided on the left side of the cabinet body 1. The opening and closing mechanism 2 is used to control the opening and closing of the ventilation opening of the cabinet body 1. An inspection mechanism 3 is provided on the rear side of the interior of the cabinet body 1. The inspection mechanism 3 is used to detect different positions inside the cabinet body 1. Partitions 5 are provided on the upper and lower sides of the interior of the cabinet body 1. The partitions 5 divide the interior of the cabinet body 1 into multiple independent storage compartments to realize the layered and classified storage of lithium batteries. A fixing mechanism 4 is provided on the top of the partitions 5. The fixing mechanism 4 is used to fix the lithium batteries.

[0032] The opening and closing mechanism 2 includes a ventilation shell 21, which guides the airflow inside the cabinet into the air duct 6. The ventilation shell 21 is fixedly connected to the left side of the outer wall of the cabinet 1. Multiple rotating shafts 22 are rotatably connected inside the ventilation shell 21. The rotating shafts 22 transmit the power of the servo motor 27 and drive the gear 23 to rotate synchronously. The gears 23 are fixedly connected to the front and rear sides of the outer walls of the multiple rotating shafts 22. The gears 23 convert the rotational power of the servo motor 27 into the linear motion of the rack 25. Multiple sliding plates 24 are slidably connected to the right side of the inner wall of the ventilation shell 21. The sliding plates 24 provide a sliding mounting base for the baffle 26 and drive the baffle 26 to rise synchronously. The inner sides of multiple sliding plates 24 are slidably connected to baffles 26. The front and rear ends of the right side of the ventilation shell 21 are provided with racks 25. The racks 25 receive the power of gears 23 and drive the sliding plates 24 and baffles 26 to move up and down. The front and rear ends of the left sides of multiple sliding plates 24 are fixedly connected to the right ends of the corresponding racks 25. The racks 25 are meshed with the corresponding gears 23. The upper middle part of the front side of the outer wall of the ventilation shell 21 is fixedly connected to a servo motor 27. The output end of the servo motor 27 passes through the ventilation shell 21 and is fixedly connected to the corresponding rotating shaft 22. The left side of the sliding plate 24 is provided with a linkage component 28.

[0033] The linkage component 28 includes multiple limiting rings 281, which guide and limit the slide rod 282 to ensure that the slide rod 282 slides smoothly in a straight line. The multiple limiting rings 281 are fixedly connected to the bottom left side of the corresponding slide plate 24. The same slide rod 282 is slidably connected inside the multiple limiting rings 281. The slide rod 282 is the mounting carrier of the electromagnet 286 and transmits the power of the servo motor 284 to drive the designated baffle 26 to rise and fall. The top front end of the slide rod 282 is fixedly connected with teeth. Rack 283 meshes with gear 285, receives power from servo motor 284 and drives slide bar 282 to move up and down. Servo motor 284 is fixedly connected to the upper left side of the outer wall of ventilation shell 21. Servo motor 284 provides rotational power to gear 285, driving slide bar 282 and adsorption baffle 26 to rise and fall separately. The output end of servo motor 284 passes through ventilation shell 21 and is fixedly connected to gear 285. Gear 285 meshes with rack 283.

[0034] The opening and closing mechanism 2 also includes ventilation slots 29. Multiple ventilation slots 29 are provided on the left side of the inner wall of the cabinet 1. The ventilation slots 29 are the communication channels between the airflow inside the cabinet and the ventilation shell 21, so as to realize the exhaust of heat and gas from each partition. The positions of the multiple ventilation slots 29 match the positions of the corresponding baffles 26.

[0035] The linkage component 28 also includes multiple electromagnets 286. The left ends of the multiple electromagnets 286 are fixedly connected to the right end of the slide bar 282. When the electromagnets 286 are energized, they generate magnetic force to attract the iron block 287, thereby realizing the linkage fixation between the designated baffle 26 and the slide bar 282. The bottom left side of the multiple baffles 26 is fixedly connected to the iron block 287. The iron block 287 cooperates with the electromagnets 286 to provide a linkage force point for the individual lifting and lowering of the baffle 26. The positions of the multiple electromagnets 286 and the iron block 287 are matched.

[0036] Specifically, when the storage cabinet is in normal working condition, multiple baffles 26 remain at a preset height and do not obstruct the ventilation slots 29. The axial flow fan 9 generates negative pressure suction, and the heat generated by each compartment in the cabinet 1 enters the left ventilation shell 21 through the corresponding ventilation slots 29, then flows into the air duct 6 from the ventilation shell 21, and finally is exhausted outside the cabinet by the axial flow fan 9, achieving balanced ventilation and heat dissipation. When the detector detects a battery malfunction in a certain compartment, such as an increase in temperature or an excessive concentration of combustible gas, the servo motor 27 starts, driving the connected rotating shaft 22 and the corresponding gear 23 to rotate synchronously. Because the gear 23 meshes with the vertically installed rack 25, the rotation of the gear is converted into the linear motion of the rack, causing all the slides 24 to rotate. The baffle 26 slides downward synchronously under the action of rack 25, thereby blocking the ventilation slot 29. Then, the electromagnet 286 at the corresponding height of the faulty partition is energized, attracting the iron block 287 on the baffle 26 of that layer. Subsequently, the servo motor 284 starts and drives the gear 285 to rotate. The gear 285 drives the rack 283 and slide bar 282 that mesh with it to move upward as a whole. The iron block 287 attracted by the electromagnet 286 drives the baffle 26 to move upward along the slide plate 24, reopening the corresponding ventilation slot 29. The other ventilation slots 29 are closed, and only the ventilation slot 29 of the faulty layer remains unobstructed. The suction force of the axial flow fan 9 is concentrated on this compartment, quickly removing heat, combustible gas and toxic fumes, and expelling them outside the cabinet through the air duct 6.

[0037] Reference Figure 3 , Figure 4 and Figure 6The inspection mechanism 3 includes two drive wheels 31 and a drive belt 32. The two drive wheels 31 are rotatably connected to the upper and lower ends of the rear side inside the cabinet 1, respectively. The drive wheels 31 are the support and transmission components of the drive belt 32, driving the drive belt 32 to move in a circular motion. The two drive wheels 31 are connected by the drive belt 32. The drive belt 32 drives the connecting block 34 and the mounting plate 35 to move up and down reciprocally through the circular motion. A servo motor 33 is fixedly connected to the upper middle part of the rear side of the cabinet 1. The output end of the servo motor 33 passes through the rear end of the cabinet 1 and is fixedly connected to the corresponding drive wheel 31. A connecting block 34 is fixedly connected to the right side of the outer wall of the drive belt 32. The connecting block 34 realizes power transmission and drives the mounting plate 35 to move synchronously. A mounting plate 35 is provided on the front side of the transmission belt 32. The mounting plate 35 drives the detector to move up and down with the transmission belt 32. The connecting block 34 is fixedly connected to the inner right end of the mounting plate 35. A combustible gas detector 36 is provided on the front left end of the mounting plate 35. The combustible gas detector 36 collects the combustible gas concentration parameters in the cabinet in real time. A temperature and humidity detector 37 is provided in the middle of the front side of the mounting plate 35. The temperature and humidity detector 37 collects the temperature and humidity parameters in the cabinet in real time and provides early warning of battery overheating or humid environment risks. A toxic and harmful gas detector 38 is provided on the front right end of the mounting plate 35. The toxic and harmful gas detector 38 collects the toxic and harmful gas concentration parameters in the cabinet in real time to ensure the health and safety of the operators.

[0038] The inspection mechanism 3 also includes two slide rails 39, which provide sliding guidance for the mounting plate 35. The two slide rails 39 are fixedly connected to the left and right sides of the rear end of the cabinet 1, respectively, and the left and right sides of the rear end of the mounting plate 35 are slidably connected to the outer wall of the corresponding slide rail 39.

[0039] Specifically, the output of servo motor 33 drives the upper transmission wheel 31 to rotate. The upper transmission wheel 31 then transmits power to the lower transmission wheel 31 through the transmission belt 32. Through the alternating forward and reverse rotation of servo motor 33, the mounting plate 35, which is connected to the transmission belt 32 through the connecting block 34, can move up and down with the transmission belt 32. The slide rail 39 can ensure the stability of the mounting plate 35 during the up and down reciprocating motion. The combustible gas detector 36, temperature and humidity detector 37, and toxic and harmful gas detector 38, which are fixed to the front of the mounting plate 35, will move up and down with the mounting plate 35, passing through each compartment in the cabinet 1, and collecting environmental parameters at different heights and positions in the cabinet. If an abnormality is detected in the parameters of a certain compartment, it will be linked with servo motor 1 27 and servo motor 2 284 to exhaust and dissipate heat in that compartment.

[0040] Reference Figure 1 , Figure 4 and Figure 7The fixing mechanism 4 includes multiple fixing blocks 41, which provide rotational support for the lead screw 42 and limit the movement range of the slider 43. The bottoms of the multiple fixing blocks 41 are respectively fixedly connected to the top left and right sides of the corresponding partition 5. The lead screw 42 is rotatably connected inside each of the multiple fixing blocks 41. The lead screw 42 drives the slider 43 to move horizontally through threaded engagement. The slider 43 is threadedly connected to the outer wall of each of the multiple lead screw 42. The slider 43 moves horizontally through the rotational power of the lead screw 42, pushing the rotating rod 44 to swing. The rotating rod 44 is rotatably connected to one side of the outer wall of each of the multiple sliders 43. The rotating rod 44 converts the horizontal movement of the slider 43 into the linear movement of the clamping plate 45. The clamping plate 45 is rotatably connected to one side of each of the multiple rotating rods 44. The clamping plate 45 fits against the side of the battery from the left and right sides to clamp and fix the battery. The bottom of each of the multiple clamping plates 45 is fixedly connected to a sliding column 47, which provides movement guidance for the clamping plate 45. The two partitions 5 Guide grooves 46 are provided on both the left and right sides of the top. The guide grooves 46 limit the movement trajectory of the sliding column 47, ensuring that the clamping plate 45 moves smoothly along a straight line. Multiple sliding columns 47 are slidably connected to the inner wall of the corresponding guide groove 46. Cabinet doors 14 are rotatably connected to the left and right sides of the front end of the cabinet 1. The cabinet doors 14 seal the internal space of the cabinet 1, preventing the intrusion of external dust and moisture. Multiple automatic fire extinguishers 12 are provided on the right side of the inner wall of the cabinet 1. When the automatic fire extinguisher 12 detects a battery malfunction and combustion, it will automatically activate to accurately extinguish the fire source and prevent the fire from spreading. A leakage tray 13 is provided at the bottom of the cabinet 1. The leakage tray 13 collects the electrolyte leaked from the lithium battery to prevent the electrolyte from corroding the cabinet 1 or causing secondary safety hazards. Multiple support plates 15 are fixedly connected to the left and right sides of the inside of the cabinet 1. The support plates 15 are used to support the partition 5, realizing the quick assembly and stable positioning of the partition 5. The bottom left and right sides of the two partitions 5 are slidably connected to the inner side of the corresponding support plate 15.

[0041] Specifically, the bottom of the partition 5 is inserted into the support plate 15, which supports the partition 5. When it is necessary to store the battery, the battery is placed on top of the partition 5. By manually rotating the lead screw 42, the slider 43 moves horizontally within the fixed block 41 under the action of the threaded engagement of the lead screw 42. The movement of the slider 43 pushes the rotating rod 44 to swing. The other end of the rotating rod 44 is rotatably connected to the clamping plate 45, and a sliding post 47 is fixed at the bottom of the clamping plate 45. The sliding post 47 can only slide along the inner wall of the guide groove 46. Therefore, when the rotating rod 44 is in the slider 43 When pushed and swung, the swaying is converted into the linear movement of the clamping plate 45 along the guide groove 46, so that the clamping plate 45 is evenly attached to the side surface of the battery. By clamping the battery from the left and right sides simultaneously with the two clamping plates 45, it can accommodate different models of batteries and fix them in the center of the partition 5 to prevent battery displacement and shaking, and ensure the stability of the battery during storage and charging. When the battery inside the cabinet 1 malfunctions and burns, the automatic fire extinguisher 12 is activated to extinguish the fire. The battery leakage falls into the leakage tray 13 at the bottom of the cabinet 1.

[0042] Reference Figure 1 , Figure 4 and Figure 8 The top left end of the cabinet 1 has an air duct 6, which is a concentrated airflow channel that guides the airflow inside the ventilation shell 21 into the ventilation pipe 8. The top inside of the cabinet 1 has a connecting port 7, which connects the airflow inside the cabinet 1 with the air duct 6. The top of the cabinet 1 is connected to the ventilation pipe 8, which provides a mounting carrier for the axial flow fan 9 and guides the airflow to be discharged to the outside. The axial flow fan 9 is installed inside the ventilation pipe 8. After the axial flow fan 9 is started, it generates a negative pressure suction force. The top of the ventilation pipe 8 is fixedly connected to the mounting plate 10, which provides a mounting base for the locking buckle 11, making it easy for the ventilation pipe 8 to be connected to the outdoor pipe. The outer wall of the mounting plate 10 is provided with the locking buckle 11, which is used to fasten the connection between the ventilation pipe 8 and the outdoor pipe.

[0043] Specifically, when the axial fan 9 is started, the airflow inside the cabinet 1 enters the air duct 6 through the connecting port 7, and then enters the ventilation pipe 8 through the air duct 6 and is discharged from the cabinet 1 by the axial fan 9. The connecting port 7 connects the air duct 6 with the inside of the cabinet 1. The mounting plate 10 and the locking buckle 11 are used to connect the outdoor pipe to facilitate the exhaust of gas to the outside.

[0044] Working principle: Under normal conditions, multiple baffles 26 remain at preset heights, not obstructing the ventilation slots 29. The axial fan 9 generates negative pressure suction, and the heat generated by each compartment within the cabinet 1 enters the ventilation shell 21 on the left side through the corresponding ventilation slots 29. From there, the heat flows into the air duct 6 and is exhausted outside the cabinet by the axial fan 9, achieving balanced ventilation and heat dissipation. When a detector detects a battery malfunction in a compartment, resulting in a temperature increase or excessive combustible gas concentration, the servo motor 27 starts, driving the connected rotating shaft 22 and the corresponding gear 23 to rotate synchronously. Since the gear 23 meshes with the vertically mounted rack 25, the rotation of the gear is converted into the linear motion of the rack, causing all the slides 24 to engage with the baffles. The plate 26 slides down synchronously under the drive of the rack 25, blocking the ventilation slot 29. Then, the electromagnet 286 at the corresponding height of the faulty partition is energized and attracts the iron block 287 on the baffle 26 of that layer. Subsequently, the servo motor 284 starts and drives the gear 285 to rotate. The gear 285 then drives the meshing rack 283 and slide bar 282 to move upward as a whole. The iron block 287 attracted by the electromagnet 286 drives the baffle 26 to move upward along the slide plate 24, reopening the corresponding ventilation slot 29. The other ventilation slots 29 are closed, and only the ventilation slot 29 of the faulty layer remains unobstructed. The suction force of the axial flow fan 9 is concentrated on this compartment, quickly removing heat, combustible gas and toxic fumes, and expelling them outside the cabinet through the air duct 6.

[0045] Furthermore, the output end of servo motor 33 drives the upper transmission wheel 31 to rotate, and then the upper transmission wheel 31 transmits power to the lower transmission wheel 31 through the transmission belt 32. Through the alternating forward and reverse rotation of servo motor 33, the mounting plate 35 connected to the transmission belt 32 through the connecting block 34 can move up and down with the transmission belt 32. The slide rail 39 ensures the stability and straightness of the mounting plate 35 during the up and down reciprocating motion. The combustible gas detector 36, temperature and humidity detector 37 and toxic and harmful gas detector 38 fixed on the front side of the mounting plate 35 move up and down through each compartment in the cabinet 1, collecting environmental parameters at different heights and positions in the cabinet. When an abnormality is detected in the parameters of a certain compartment, it is linked with servo motor 1 27 and servo motor 2 284 to quickly exhaust and dissipate heat in the compartment.

[0046] Finally, when it is necessary to store the battery, place the battery on top of the separator 5 and rotate it manually by rotating the lead screw 42. The slider 43, which is connected to the lead screw 42 by a thread, moves horizontally along the fixed block 41 under the thread engagement of the lead screw 42. The movement of the slider 43 pushes the rotating rod 44 to swing. Since the other end of the rotating rod 44 is rotatably connected to the clamping plate 45, and the bottom of the clamping plate 45 is fixed with a sliding column 47, the sliding column 47 can only slide along the inner wall of the guide groove 46. Therefore, when the rotating rod 44 swings under the push of the slider 43, it will convert the swing into the linear movement of the clamping plate 45 along the guide groove 46, so that the clamping plate 45 is evenly attached to the side surface of the battery. By clamping the battery simultaneously from the left and right sides with two clamping plates 45, it can accommodate different types of batteries and fix them in the center position of the separator 5 to prevent the battery from shifting or shaking.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
