Description

Technical Field

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

[0002] Storage batteries are a crucial component of power systems, serving as backup power sources to ensure a rapid switch to power supply in the event of a main power failure. They provide DC power to protection devices, automation systems, control systems, and other equipment. During storage and transportation, batteries may suffer varying degrees of damage or performance degradation due to environmental factors, transportation conditions, and other influences. Therefore, storage enclosures are necessary to protect the batteries.

[0003] For example, the utility model patent with authorization announcement number CN214411308U discloses a storage and transportation box for recycling waste lead-acid batteries, belonging to the field of renewable resource recycling. A feed inlet cover is installed on the feed inlet at the top of the box; a discharge door is located on one side of the box, hinged to the box via a hinge shaft, and a discharge door pin is located at the bottom of the box; a bottom beam is connected to the bottom surface outside the box, and a discharge device is connected to the bottom surface inside the box; a waste acid collection tank is located on the bottom surface of the box at the discharge end of the discharge device, and a shut-off valve is connected to the bottom of the waste acid collection tank leading to the outside of the box; a controller box is connected to the bottom of the box, containing a controller; the controller's control panel is located on the box, and the control panel has an input control port connected to an external driver; the controller's output control terminal is connected to the lifting device of the discharge device.

[0004] Although the storage and transportation boxes in the aforementioned patents can minimize the potential hazards of waste batteries to human health and the environment, existing storage and transportation boxes have certain defects in use. During storage and transportation, when encountering fire problems caused by battery failure, the existing storage and transportation boxes lack the ability to detect the location of the failure and the faulty battery, making it difficult for staff to quickly detect the fire and locate the storage and transportation box and battery where the fire occurred, which can easily cause the fire to spread and cause a large amount of battery damage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a power battery storage and protection device to solve the problems mentioned in the background art and achieve rapid detection and location of battery faults.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power battery storage and protection device, comprising a housing and a cover connected to the housing. Two main partitions are fixedly connected inside the housing, and a lower partition is fixedly connected to the bottom surface of the housing in another direction. The lower partition is perpendicularly fixedly connected to the middle of the main partitions, and the height of the lower partition is half that of the main partitions. Three placement plates are slidably connected to the surface of the lower partition, and the main partitions separate the placement plates one by one. Upper partitions corresponding to the positions of the lower partitions are fixedly connected to the surface of each placement plate. One end of each placement plate is connected to the inner wall of the housing via a rotating assembly. Multiple mounting platforms are fixedly connected to the bottom surface of each placement plate and the bottom surface of the cover. These mounting platforms are separated by the main partitions, upper partitions, and lower partitions. Each mounting platform has a threaded groove on its bottom surface. A connecting block is threaded into the threaded groove. An installation groove is opened on the bottom surface of the connecting block. A temperature sensor is fixedly connected in the installation groove. A fire extinguishing component is connected in the connecting block.

Both the wireless transmission device and the light board are electrically connected to the temperature sensor.

[0007] The fire extinguishing assembly includes a connecting ring, a liquid storage bottle, a flow guide tube, a control valve, a connecting sleeve, a power supply battery, and a battery cover. A connecting groove is formed on the bottom surface of the connecting block, and the connecting ring is fixedly connected to the connecting groove. A placement groove is formed on the surface of the connecting block, and a liquid storage bottle is slidably connected in the placement groove. A connecting sleeve is threadedly connected to the mouth of the liquid storage bottle. The connecting sleeve and the connecting ring are connected through the flow guide tube. A control valve is fixedly connected to the middle of the flow guide tube. Perfluorohexanone is placed in the liquid storage bottle. A battery slot is formed on the surface of the connecting block, and a power supply battery is installed in the battery slot. A battery cover is snapped into the slot opening of the battery slot. The power supply battery, temperature sensor, and control valve are electrically connected. Multiple micropores are formed on the bottom surface of the connecting ring.

[0008] The rotating assembly includes a fixed block and a rotating shaft. Multiple fixed blocks are fixedly connected to the inner wall of the box body on the side away from the box cover, and a rotating shaft is fixedly connected to one side of the placement plate. The rotating shaft is rotatably connected to the fixed blocks.

[0009] Furthermore, a snap-fit ​​groove is provided on one side of the enclosure, and a mounting plate is fixedly connected in the snap-fit ​​groove. A wireless transmission device and a light panel are fixedly connected to the surface of the mounting plate.

[0010] Furthermore, a movable groove is provided on the upper part of the side of the upper partition away from the fixed block, and the corners of the movable groove are all rounded.

[0011] Furthermore, the bottom outer wall of the connecting block is provided with anti-slip texture.

[0012] Furthermore, multiple protective sleeves are slidably connected to both the bottom surface of the box and the surface of the placement plate. The protective sleeves on the surface of the placement plate correspond to the mounting platform on the bottom surface of the box cover, and the protective sleeves on the bottom surface of the box correspond to the mounting platform on the bottom surface of the placement plate.

[0013] Furthermore, a sealing ring is fixedly connected to the bottom surface of the mounting platform, and the outer wall of the sealing ring is in contact with the top side wall of the protective sleeve.

[0014] Furthermore, two symmetrically arranged elastic strips are fixedly connected to the inner wall of the top of the placement groove, and the outer wall of the elastic strips is in contact with the outer wall of the liquid storage bottle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) A power battery storage and protection device uses temperature sensors to realize real-time detection of batteries, so that when a battery fire occurs, the staff can detect it immediately. At the same time, since the temperature sensors correspond one-to-one with the battery locations, by identifying which temperature sensor issued the alarm, the staff can quickly determine the storage box and battery where the fire occurred, thus enabling rapid fire handling, thereby preventing the fire from spreading and preventing large-scale damage to the batteries. This improves the efficiency and accuracy of the staff's disaster relief efforts, reduces the damage and failure rate of batteries during storage and transportation, and thus reduces the operation and maintenance costs of the power system and improves the overall economic benefits.

[0017] (2) The design of multiple partitions and placement plates also prevents the rapid spread of fire. Even if one battery catches fire, the other batteries can remain safe to a certain extent, which buys valuable time for the rescue work of the staff.

[0018] (3) Through the wireless transmission device, the staff’s terminal equipment can receive alarm information and fire location information. At the same time, the bulbs on the light panel corresponding to the location of the fire battery will emit red light. With this setting, no matter where the staff is, they can receive the fire alarm in the first time and take countermeasures quickly to effectively curb the spread of the fire. It also makes it convenient for the staff to quickly locate the fire location and improves the overall practicality of the device.

[0019] (4) When rotating the placement plate, the staff can put their fingers into the moving groove and then hold the upper edge of the upper partition to pull up the placement plate. This setting simplifies the operation steps, improves work efficiency, and makes the whole operation process smoother and more natural. The staff no longer need to work hard to find a suitable point of force or use tools for assistance. They can complete the rotation operation of the placement plate with just a gentle pull, which improves the convenience of operation for the staff and enhances the overall performance and user experience of the product.

[0020] (5) The protective cover is made of elastic insulating fireproof and heat-insulating material, such as silicone or thermoplastic polyurethane. Before placing the battery, the protective cover is placed in the box first, and then the battery is placed in the protective cover. At this time, the bottom and sides of the battery will be tightly wrapped by the protective cover, thereby avoiding damage caused by collision, squeezing or friction during storage and transportation. The insulating performance of the protective cover can effectively isolate the current and prevent the battery from causing a fire due to short circuit or other electrical faults. At the same time, in the event of a fire, the fireproof capability of the protective cover can also prevent the spread of fire to a certain extent, winning valuable time for fire fighting and rescue.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Please see Figures 1 to 14 A power storage and protection device includes a housing 1 and a cover 2 connected to the housing 1. Two main partitions 3 are fixedly connected inside the housing 1. A lower partition 4 is fixedly connected to the bottom surface of the housing 1 in another direction. The lower partition 4 is perpendicularly fixed to the middle of the main partitions 3, and its height is half that of the main partitions 3. Three placement plates 5 are slidably connected to the surface of the lower partition 4. The main partitions 3 separate the placement plates 5 one by one. Upper partitions 6, corresponding to the positions of the lower partitions 4, are fixedly connected to the surface of each placement plate 5. One end is connected to the inner wall of the box 1 via a rotating assembly. Each placement plate 5 has multiple mounting platforms 7 fixedly connected to the bottom surface of the box cover 2. The mounting platforms 7 are separated by the main partition 3, the upper partition 6 and the lower partition 4. Each mounting platform 7 has a threaded groove 8 on its bottom surface. A connecting block 9 is threadedly connected to the threaded groove 8. The bottom surface of the connecting block 9 has an installation groove 10. A temperature sensor 11 is fixedly connected to the installation groove 10. A fire extinguishing assembly is connected to the connecting block 9. A wireless transmission assembly is connected to one side of the box 1.

[0038] The power battery storage and protection device of this invention, when in use, first removes the placement plate 5, then places the battery in the housing 1, with the batteries separated by the main partition 3 and the lower partition 4. Then, the placement plate 5 is placed on top, and the batteries are placed on it, so that the batteries are separated by the main partition 3 and the upper partition 6. The housing cover 2 can then be closed for storage and transportation. During storage and transportation, the temperature sensor 11 monitors the battery directly below in real time. If a battery malfunction causes a fire, the temperature sensor 11 will send a signal, notifying personnel via a wireless transmission component, and the fire can be temporarily extinguished using a fire extinguishing component. By utilizing the temperature sensor 11, real-time monitoring of the battery is achieved, enabling the device to respond promptly to battery fires. In the event of a fire, staff can detect it immediately. Since each temperature sensor 11 corresponds to a battery location, identifying which sensor 11 triggered the alarm allows staff to quickly determine the location of the fire in the storage box and battery, enabling rapid fire suppression and preventing the fire from spreading and causing extensive battery damage. This improves the efficiency and accuracy of firefighting efforts, reduces battery damage and failure rates during storage and transportation, lowers power maintenance costs, and enhances overall economic efficiency. The design of multiple partitions and placement plates 5 also prevents the rapid spread of fire. Even if one battery catches fire, other batteries remain relatively safe, buying valuable time for rescue operations.

[0039] As a preferred embodiment of the present invention, the fire extinguishing assembly includes a connecting ring 15, a liquid storage bottle 17, a guide tube 18, a control valve 19, a connecting sleeve 20, a power supply battery 23, and a battery cover 24. A connecting groove 32 is provided on the bottom surface of the connecting block 9, and the connecting ring 15 is fixedly connected to the connecting groove 32. A placement groove 16 is provided on the surface of the connecting block 9, and the liquid storage bottle 17 is slidably connected in the placement groove 16. A connecting sleeve 20 is threadedly connected to the mouth of the liquid storage bottle 17. The connecting sleeve 20 and the connecting ring 15 are connected through the guide tube 18. The control valve 19 is fixedly connected in the middle of the guide tube 18. Perfluorohexanone is placed in the liquid storage bottle 17. A battery slot 22 is provided on the surface of the connecting block 9, and the power supply battery 23 is installed in the battery slot 22. The battery cover 24 is snapped into the slot of the battery slot 22. The power supply battery 23, the temperature sensor 11, and the control valve 19 are electrically connected. A plurality of micropores are provided on the bottom surface of the connecting ring 15.

[0040] Specifically, when temperature sensor 11 detects a temperature change and determines that a battery fire has occurred, control valve 19 is opened. At this time, perfluoroacetone in the reservoir 17 enters the connecting ring 15 through the guide tube 18, and is then evenly sprayed onto the battery surface through the micro-holes at the bottom of the connecting ring 15, quickly extinguishing the flames and protecting the battery and the entire storage and transportation system. Compared with other fire extinguishing agents, perfluoroacetone is environmentally friendly and leaves no residue. During the fire extinguishing process, it will not pollute the environment or leave any harmful substances on the battery or storage and transportation system. It also extinguishes fires faster. At the same time, perfluoroacetone has good electrical insulation properties, which means that even if the battery is still charged during the fire extinguishing process, perfluoroacetone will not conduct electricity, thus avoiding secondary disasters caused by the electrical conductivity of the fire extinguishing agent. After a fire has occurred, the staff can rotate the connecting block 9 to remove it, exposing the reservoir 17. Then, the reservoir 17 can be removed from the placement slot 16, presenting the appearance shown in the attached figure. Figure 7 As shown in the diagram, rotating the reservoir 17 separates it from the connecting sleeve 20, allowing staff to replenish perfluoroethyl ketone (PFE) in the reservoir 17. After replenishment, the reservoir 17 is tightened to the connecting sleeve 20, and the reservoir 17 is placed in the placement slot 16. The connecting block 9 is then screwed on to complete the replenishment of PFE, ensuring that the fire extinguishing assembly can respond quickly and effectively extinguish flames in the event of another fire. The power supply battery 23 provides power to the control valve 19 and the temperature sensor 11, ensuring their normal operation and rapid response. When the power is insufficient after prolonged use, the power supply battery 23 can be replaced by opening the battery cover 24, thereby ensuring the continuous operation of the fire extinguishing assembly and the temperature sensor 11.

[0041] As a preferred technical solution of the present invention, the rotating component includes a fixing block 27 and a rotating shaft 29. Multiple fixing blocks 27 are fixedly connected to the inner wall of the box body 1 away from the box cover 2, and a rotating shaft 29 is fixedly connected to one side of the placement plate 5. The rotating shaft 29 is rotatably connected to the fixing block 27.

[0042] Specifically, when placing the battery, the staff does not need to remove the placement plate 5. They only need to pry the upper partition 6 outward to rotate the placement plate 5 around the pivot 29, as shown in the attached figure. Figure 2 As shown in the diagram, the battery can be placed on the bottom of the housing 1. The use of the fixing block 27 and the rotating shaft 29 makes it convenient for staff to place the battery, improves the placement efficiency of the staff, reduces the workload of the staff, and increases the overall practicality of the device.

[0043] As a preferred technical solution of the present invention, the wireless transmission component includes a mounting plate 12, a wireless transmission device 13 and a lamp board 14. A snap-fit ​​groove 31 is provided on one side of the housing 1. The mounting plate 12 is fixedly connected in the snap-fit ​​groove 31. The wireless transmission device 13 and the lamp board 14 are fixedly connected to the surface of the mounting plate 12. The wireless transmission device 13 and the lamp board 14 are both electrically connected to the temperature sensor 11.

[0044] Specifically, after the temperature sensor 11 detects a fire, the staff's terminal device can receive the alarm information and the location information of the fire through the wireless transmission device 13. At the same time, the bulb on the light panel 14 corresponding to the location of the battery where the fire occurred will emit a red light. With this setting, no matter where the staff is, they can receive the fire alarm in the first time, so as to take countermeasures quickly and effectively curb the spread of the fire. It also brings convenience to the staff to quickly locate the fire location and improves the overall practicality of the device.

[0045] As a preferred technical solution of the present invention, a movable groove 28 is provided on the upper part of the side of the upper partition plate 6 away from the fixed block 27, and the corners of the movable groove 28 are all rounded.

[0046] Specifically, when rotating the placement plate 5, the operator can insert their fingers into the moving groove 28 and then grasp the upper edge of the upper partition 6 to pull up the placement plate 5. This design simplifies the operation steps, improves work efficiency, and makes the entire operation process smoother and more natural. The operator no longer needs to laboriously find a suitable point of leverage or use tools for assistance; a gentle pull is all it takes to complete the rotation of the placement plate 5, improving the operator's ease of operation and enhancing the overall performance and user experience of the product. The edges and corners of the moving groove 28 are all rounded, which avoids potential safety hazards from sharp edges and corners, and makes the operation more comfortable and smooth for the operator.

[0047] As a preferred technical solution of the present invention, the bottom outer wall of the connecting block 9 is provided with anti-slip texture 30.

[0048] Specifically, the presence of anti-slip texture 30 can greatly increase the friction between the operator's fingers and the connecting block 9. When the operator needs to remove or tighten the connecting block 9, the anti-slip texture 30 can provide additional gripping force, making the operation easier and more stable. Even in wet or oily environments, it can effectively prevent fingers from slipping and ensure smooth operation.

[0049] As a preferred technical solution of the present invention, a plurality of protective sleeves 25 are slidably connected to the bottom surface of the box 1 and the surface of the placement plate 5, and the protective sleeves 25 are positioned corresponding to the mounting platform 7.

[0050] Specifically, the protective sleeve 25 is made of elastic insulating fireproof and heat-insulating material, such as silicone or thermoplastic polyurethane. Before placing the battery, the protective sleeve 25 is placed inside the housing 1, and then the battery is placed inside the protective sleeve 25. At this time, the bottom and sides of the battery will be tightly wrapped by the protective sleeve 25, thereby avoiding damage caused by collision, squeezing or friction during storage and transportation. The insulating properties of the protective sleeve 25 can effectively isolate the current and prevent the battery from causing a fire due to short circuit or other electrical faults. At the same time, in the event of a fire, the fireproof capability of the protective sleeve 25 can also, to a certain extent, prevent the spread of fire and buy valuable time for fire fighting and rescue.

[0051] As a preferred technical solution of the present invention, a sealing ring 26 is fixedly connected to the bottom surface of the mounting platform 7, and the outer wall of the sealing ring 26 is in contact with the top side wall of the protective sleeve 25.

[0052] Specifically, the sealing ring 26 is made of the same material as the protective sleeve 25. The sealing ring 26 can further enhance the protection and safeguarding capabilities of the battery, further prevent the spread of fire, and buy valuable time for personnel evacuation and fire fighting and rescue.

[0053] As a preferred technical solution of the present invention, two symmetrically arranged elastic strips 21 are fixedly connected to the inner wall of the top of the placement groove 16, and the outer wall of the elastic strips 21 is in contact with the outer wall of the liquid storage bottle 17.

[0054] Specifically, the elastic strip 21 can fix the liquid storage bottle 17 in the placement slot 16 without affecting the staff to remove the liquid storage bottle 17, thereby improving the stability of the liquid storage bottle 17 and reducing the safety hazards caused by the shaking or tipping of the liquid storage bottle 17.

[0055] 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.
