Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a new energy battery fire extinguishing experimental platform. Background Technology

[0002] With the rapid development and widespread application of new energy power lithium battery technology, its safety issues are becoming increasingly prominent. As a high-energy carrier, lithium batteries have a significantly higher risk of thermal runaway than traditional battery systems. This is especially true in large-scale applications such as lithium-ion battery energy storage containers, where battery thermal runaway is particularly problematic. When a battery experiences thermal runaway due to thermal abuse, electrical abuse, or mechanical abuse, the heat generated by the internal chemical reaction cannot be dissipated in time, causing the safety valve to rupture, leading to battery bulging, smoke, or even combustion.

[0003] Therefore, research on new energy batteries continues. Research typically requires a corresponding fire-extinguishing experimental platform to support and isolate the new energy batteries from fire. Conventional experimental platforms usually consist of a support platform, a protective cover, and a fire-extinguishing system. However, in practical applications, it has been found that conventional protective covers are mostly integrated structures, usually lifted from the top for inserting and removing the new energy batteries. Because the protective covers are typically quite tall, this is inconvenient for actual lifting operations, and the lifting equipment occupies a large space. Therefore, a new energy battery fire-extinguishing experimental platform is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a new energy battery fire extinguishing experimental platform to address the aforementioned technical problems. Through the linkage design of the height adjustment unit and the experimental platform, precise lifting and lowering of the platform within the experimental enclosure is achieved. This not only avoids the inconvenience of hoisting large enclosures in traditional experiments but also enables rapid placement and removal of battery samples via a sliding experimental support. The height adjustment unit uses a servo motor to drive a bidirectional threaded screw, which in turn drives the adjusting arm to control the smooth lifting and lowering of the platform, simplifying the experimental operation process and reducing labor intensity and operational risks.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A new energy battery fire extinguishing experimental platform includes a support base and a support frame located at the top edge of the support base. Experimental covers are installed at both ends of the support frame. An opening slot is located below the experimental cover. An experimental platform is embedded in the opening slot. An energy-absorbing buffer unit is connected to the bottom of the experimental platform. The experimental platform is equipped with a height adjustment unit for connecting to the support base through the energy-absorbing buffer unit.

[0007] The energy-absorbing buffer unit includes a connecting base plate fixed at the four corners of the bottom of the experimental platform and a sliding seat slidably disposed in the connecting base plate. Damping shock absorbers are fixedly connected to both sides of the sliding seat, and the outer ends of the damping shock absorbers are fixed to the experimental platform.

[0008] Furthermore, the height adjustment unit includes a first guide seat and a second guide seat fixed to the surface of the support base. Lower sliding seats are slidably mounted on both sides of the top of the first guide seat and the second guide seat. An adjustment arm is hinged to the surface of the lower sliding seat and is hinged to the sliding seat.

[0009] Furthermore, there are four lower sliding seats, with two lower sliding seats forming a group, and two lower connecting rods connected together in each group. A driving component is mounted on the surface of the two lower connecting rods.

[0010] Furthermore, an upper connecting rod is connected between two adjacent sliding seats.

[0011] Furthermore, the driving component includes a housing fixedly mounted on the support base and a guide groove formed on the surface of the housing, and the lower connecting rod is slidably assembled with the housing through the guide groove.

[0012] Furthermore, the drive unit also includes a bidirectional threaded screw that is threaded together on the surfaces of the two lower connecting rods, and one end of the bidirectional threaded screw is connected to a servo motor that is connected to the side wall of the housing.

[0013] Furthermore, an experimental support seat is slidably mounted on the top of the experimental platform, and the edge of the experimental support seat has a retaining protrusion.

[0014] Furthermore, a sealing groove adapted to the enclosure boss is provided at the bottom of the side wall of the experimental enclosure.

[0015] Furthermore, an extinguishing agent delivery pipe is installed inside the experimental enclosure, and an extinguishing agent nozzle is installed on the surface of the extinguishing agent delivery pipe. One end of the extinguishing agent delivery pipe passes through the experimental enclosure for connection with an external extinguishing agent supply tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The new energy battery fire extinguishing experimental platform provided by this utility model achieves precise lifting and lowering of the experimental platform within the experimental enclosure through the linkage design of the height adjustment unit and the experimental platform. This not only avoids the inconvenience of hoisting large enclosures in traditional experiments, but also enables the rapid placement and removal of battery samples through a sliding experimental support. The height adjustment unit uses a servo motor to drive a bidirectional threaded screw, which in turn drives the adjusting arm to control the smooth lifting and lowering of the platform, simplifying the experimental operation process and reducing labor intensity and operational risks.

[0018] The combination of damping shock absorbers and sliding seats in the energy-absorbing buffer unit effectively absorbs the impact energy generated by battery thermal runaway. When a violent reaction or explosion occurs during battery experiments, the damping shock absorbers dissipate energy through deformation, mitigating the impact on the supporting structure. At the same time, the upper connecting rod strengthens the linkage between adjacent sliding seats, further enhancing the stability of the experimental platform. Attached Figure Description

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0033] Example 1

[0034] Please refer to Figures 1-5 As shown, a new energy battery fire extinguishing experimental platform includes a support base 1 and a support frame 2 located at the top edge of the support base 1. An experimental cover 3 is installed at both ends of the support frame 2. An opening slot 31 is located below the experimental cover 3. An experimental platform 4 is embedded in the opening slot 31. An energy-absorbing buffer unit 5 is connected to the bottom of the experimental platform 4. A height adjustment unit 6 for connecting to the support base 1 is installed on the experimental platform 4 through the energy-absorbing buffer unit 5.

[0035] The energy-absorbing buffer unit 5 includes a connecting base plate 51 fixed at the four corners of the bottom of the experimental platform 4 and a sliding seat 52 slidably disposed within the connecting base plate 51. Damping shock absorbers 53 are fixedly connected to both sides of the sliding seat 52, and the outer ends of the damping shock absorbers 53 are fixed to the experimental platform 4. Through the combined design of the damping shock absorbers 53 and the sliding seats 52 in the energy-absorbing buffer unit 5, the impact energy generated by battery thermal runaway can be effectively absorbed. When a violent reaction or explosion occurs during the battery experiment, the damping shock absorbers 53 dissipate energy through deformation, mitigating the impact on the supporting structure. Simultaneously, the adjacent sliding seats 52 are reinforced with an upper connecting rod 54, further enhancing the stability of the experimental platform.

[0036] The experimental enclosure 3 in this embodiment can be made of high-temperature and corrosion-resistant materials, such as stainless steel or a multi-layer steel structure coated with fire-retardant paint, to withstand the high temperatures (usually exceeding 800°C) and corrosive gases that may be generated during battery thermal runaway.

[0037] In addition, observation windows (such as explosion-proof glass windows, not shown in the figure) can be opened on the side of the experimental enclosure 3 to facilitate real-time observation of experimental phenomena, and sensor mounting holes are reserved for arranging data acquisition equipment such as thermocouples and smoke sensors (not shown in the figure). Since the specific structure and principle of battery fire extinguishing are already well known to those skilled in the art, no further elaboration is required in this embodiment.

[0038] Example 2

[0039] The fire extinguishing experimental platform for new energy batteries provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the height adjustment unit 6 includes a first guide seat 61 and a second guide seat 62 fixed to the surface of the support base 1. Lower sliding seats 63 are slidably mounted on both sides of the top of the first guide seat 61 and the second guide seat 62. An adjustment arm 64 is hinged to the surface of the lower sliding seat 63 and is hinged to the sliding seat 52.

[0040] There are four lower sliding seats 63. Two lower sliding seats 63 are divided into two groups. The two lower sliding seats 63 in each group are connected by a lower connecting rod 65. The surfaces of the two lower connecting rods 65 are jointly mounted with a driving component 7.

[0041] The two adjacent sliding seats 52 are connected by an upper connecting rod 54.

[0042] Because the new energy battery fire extinguishing experimental platform of this utility model has the above structure, the driving component 7 can synchronously drive the two lower connecting rods 65 at the bottom, so that they move closer or further apart. This allows the lower sliding seat 63 and its adjusting arm 64 to swing at an angle, thereby adjusting the height of the experimental platform 4. This allows the experimental platform 4 to be raised to the bottom of the experimental cover 3 and placed in contact with it for the experiment. At the same time, it can be lowered to a certain height at the bottom of the experimental cover 3, which facilitates the cleaning of the battery after the experiment.

[0043] Example 3

[0044] The fire extinguishing experimental platform for new energy batteries provided in Example 2 has been further optimized, such as... Figure 4 As shown, the driving component 7 includes a housing 71 fixedly mounted on the support base 1 and a guide groove 72 formed on the surface of the housing 71. The lower connecting rod 65 is slidably assembled with the housing 71 through the guide groove 72.

[0045] The drive unit 7 also includes a bidirectional threaded screw 73 that is threadedly connected to the surfaces of the two lower connecting rods 65. One end of the bidirectional threaded screw 73 is connected to a servo motor 74 that is connected to the side wall of the housing 71.

[0046] Because the new energy battery fire extinguishing experimental platform of this utility model has the above structure, the servo motor 74 is started so that one end drives the bidirectional threaded screw 73 to rotate. In this way, the bidirectional threaded screw 73 forms a threaded engagement with the two corresponding lower connecting rods 65 through its two opposite threaded sections, which can drive the two lower connecting rods 65 to slide along the guide groove 72, so that they move closer or further apart from each other.

[0047] In this embodiment, the linkage design between the height adjustment unit 6 and the experimental platform 4 enables precise lifting and lowering of the experimental platform 4 within the experimental enclosure 3. This not only avoids the inconvenience of hoisting large enclosures in traditional experiments, but also allows for the rapid placement and removal of battery samples through the sliding experimental support 41. The height adjustment unit 6 uses a servo motor 74 to drive a bidirectional threaded screw 73, which in turn drives the adjusting arm 64 to control the smooth lifting and lowering of the platform, simplifying the experimental operation process and reducing labor intensity and operational risks.

[0048] Example 4

[0049] The fire extinguishing experimental platform for new energy batteries provided in Example 3 has been further optimized, such as... Figure 2 As shown, the experimental platform 4 is slidably fitted with an experimental support seat 41 on its top. The edge of the experimental support seat 41 has a retaining protrusion 42. Through the design of the experimental support seat 41, after the experimental platform 4 is lowered, the experimental support seat 41 can be slid on one side, which can increase the operating space for the new energy battery on it and make it more convenient to use.

[0050] The bottom of the side wall of the experimental enclosure 3 is provided with a sealing groove 32 that is compatible with the enclosure boss 42.

[0051] Example 5

[0052] The fire extinguishing experimental platform for new energy batteries provided in Example 3 has been further optimized, such as... Figure 5 As shown, an extinguishing agent delivery pipe 33 is installed inside the experimental enclosure 3, and an extinguishing agent nozzle 34 is installed on the surface of the extinguishing agent delivery pipe 33. One end of the extinguishing agent delivery pipe 33 passes through the experimental enclosure 3 for connection with an external extinguishing agent supply tank.

[0053] The extinguishing agent delivery pipe 33 can be arranged in a ring or with multiple branches to ensure that the extinguishing agent nozzle 34 can cover the entire area of ​​the experimental support 41. The extinguishing agent delivery pipe 33 can be connected to various external extinguishing agent supply systems, such as fine water mist systems, compressed air foam systems, or clean gas extinguishing systems such as liquid nitrogen, to conduct comparative performance tests of different extinguishing agents. Flow meters and pressure sensors can also be installed on the pipe to monitor and provide feedback on the extinguishing agent spray parameters in real time (not shown in the figure).
