[0026] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0029] An embodiment of the present utility model discloses a battery acupuncture test device, which performs acupuncture tests on the battery 6 and can extinguish the fire in time when the battery 6 catches fire.

[0030] Reference can be made to Figures 1 - 5 , this battery acupuncture test device may specifically include a test main body 1, a lifting platform 2 and a fire extinguishing nozzle 3; a hollow cavity 11 is arranged inside the test main body 1 along its height direction, an opening 12 communicating with the hollow cavity 11 is arranged on the outer side wall of the test main body 1, and the opening 12 is used for the piercing work of the test needle 5; the lifting platform 2 is used for placing the battery 6, the lifting platform 2 is arranged inside the hollow cavity 11 and can lift along the height direction inside the hollow cavity 11; the fire extinguishing nozzle 3 is arranged inside the hollow cavity 11 and is located above the battery 6. After the battery 6 catches fire, the lifting platform 2 rises close to the fire extinguishing nozzle 3 to shorten the distance between the battery 6 and the fire extinguishing nozzle 3.

[0031] In specific implementation, the lifting platform 2 can be specifically lifted to the opening 12 of the test body 1. The battery 6 can be specifically placed on the lifting platform 2 from the opening 12. When performing the needle puncture test, the needle tip of the test needle 5 will penetrate from the opening 12 of the test body 1 to perform the needle puncture test on the battery 6. After the needle puncture experiment is completed and there is a risk of fire for the battery 6, the fire extinguishing sprinkler 3 located above the battery 6 will spray a water flow containing a fire extinguishing medium. At this time, the test needle 5 is withdrawn, and at the same time, the lifting platform 2 starts to rise and approach the fire extinguishing sprinkler 3. Since the distance between the burning battery 6 and the fire extinguishing sprinkler 3 becomes smaller, the battery can contact the fire extinguishing water flow faster. At the same time, the relatively short distance also prevents the atomization of the fire extinguishing water flow, enabling the fire of the burning battery 6 to be extinguished more quickly.

[0032] In summary, this battery needle puncture test device also has a lifting function during the needle puncture test, which can enable the burning battery to contact the fire extinguishing water flow faster. At the same time, the relatively short distance also prevents the atomization of the fire extinguishing water flow, effectively improving the fire extinguishing efficiency and ability. At the same time, this battery needle puncture test device, with the help of the sprinkler and the lifting platform 2, enables the operator not to face the burning battery 6, greatly improving safety.

[0033] In an alternative embodiment, the overall shape of the test body 1 can be cylindrical, for example, it can be a circular tube structure, which has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.

[0034] In an alternative embodiment, the overall shape of the lifting platform 2 can also be adapted to the test body 1 with a circular tube structure, for example, it can be cylindrical, which can better fit the hollow cavity 11 of the test body 1. At the same time, it has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.

[0035] In an alternative embodiment, the hollow cavity 11 runs through the top and bottom of the test body 1 in the height direction. Such a setting facilitates the more convenient assembly of both the fire extinguishing sprinkler 3 and the lifting platform 2, and has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.

[0036] In an alternative embodiment, the lifting platform 2 can be specifically connected with a telescopic cylinder or a telescopic motor to drive the lifting of the lifting platform 2, which has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.

[0037] In an alternative embodiment, the lifting platform 2 is configured to rise at least above the opening 12 of the test body 1 when the battery 6 catches fire, and the lifting platform 2 and the inner side wall of the hollow cavity 11 form a closed space. With such a setting, after the needle-punching experiment is completed and there is a risk of the battery 6 catching fire, the lifting platform 2 starts to rise close to the fire extinguishing nozzle 3, and the rising height of the lifting platform 2 will also exceed the top of the opening 12 of the test body 1 and be located above the opening 12, so that the lifting platform 2 and the inner cavity wall of the hollow cavity 11 form a relatively closed space, effectively preventing the fire extinguishing water flow from dissipating. After the fire extinguishing reaches a certain time, the fire extinguishing water flow ejected by the nozzle will fully soak the needle-punched battery 6, further improving the fire extinguishing efficiency. Moreover, after the fire extinguishing is completed, the lifting platform 2 is lowered, and the fire extinguishing water flow can flow out from the opening 12, facilitating subsequent operation by the operator.

[0038] Optionally, the diameter of the lifting platform 2 is equal to the inner diameter of the hollow cavity 11 to form a relatively closed space.

[0039] Optionally, the diameter of the lifting platform 2 is smaller than the inner diameter of the hollow cavity 11. Since there is a risk of the battery 6 catching fire, a part of the fire extinguishing water flow ejected by the nozzle may flow out from the gap between the lifting platform 2 and the hollow cavity 11. However, as long as the flow rate of the ejected fire extinguishing water flow is set to be greater than the flow rate that flows away, after the fire extinguishing reaches a certain time, the fire extinguishing water flow will fully soak the needle-punched battery 6.

[0040] In an alternative embodiment, in order to further prevent the fire extinguishing water flow from dissipating, a groove 21 is provided on the upper end surface of the lifting platform 2 facing the nozzle, and the groove 21 is used to place the battery 6. With such a setting, the lifting platform 2 can collect the fire extinguishing water flow by using the groove 21, accelerate the accumulation of the fire extinguishing water flow, and more quickly and fully soak the needle-punched battery 6, further improving the fire extinguishing efficiency.

[0041] In an alternative embodiment, at least one end of the groove 21 extends to the outer side wall of the lifting platform 2 to form an open end. When the lifting platform 2 is disposed at the opening 12 of the test body 1, the open end of the groove 21 is arranged facing the opening 12 of the test body 1. Since the lifting platform 2 needs to be lowered after the fire extinguishing is completed and the fire extinguishing water flow can flow out from the opening 12, and at the same time, a certain amount of fire extinguishing water flow will remain in the groove 21, the structure of the groove 21 is designed such that the groove 21 has an open end, so that the remaining fire extinguishing water flow can flow out of the groove 21 from the open end and then flow out from the opening 12 of the test body 1, avoiding the remaining fire extinguishing water flow in the groove 21 and thus affecting the efficiency of subsequent needle-punching tests.

[0042] In an alternative embodiment, two openings 12 are provided on the outer sidewall of the test body 1, and the groove 21 is provided with two open ends, and one open end of a groove 21 corresponds to one opening 12 of the test body 1. Such a setting facilitates the more rapid discharge of the fire extinguishing water flow and further improves the efficiency of the acupuncture test.

[0043] Regarding the position design of the two openings 12 on the test body 1 and the two open ends on the groove 21, for example, the two openings 12 on the test body 1 are arranged facing each other, and can be specifically in a straight line shape, and the two open ends on the groove 21 are arranged facing each other, and can also be specifically in a straight line shape; also for example, the two openings 12 on the test body 1 can be arranged in an L shape, and the two open ends on the groove 21 can also be arranged in an L shape.

[0044] In order to better fix the battery 6 in the groove 21 of the lifting platform 2, in an alternative embodiment, a fixing member for fixing the battery 6 is provided in the groove 21. After the fixing member fixes the battery 6, in the height direction, the upper end surface of the battery 6 does not protrude from the upper end surface of the lifting platform 2. Such a setting, when the lifting platform 2 rises, so that a relatively sealed space is formed between the lifting platform 2 and the inner cavity wall of the hollow cavity 11, sufficient fire extinguishing water flow will quickly accumulate in the groove 21 of the lifting platform 2 first, and the battery 6 after acupuncture can be more quickly and fully wetted, further improving the fire extinguishing efficiency.

[0045] In an alternative embodiment, along the direction in which the test needle 5 penetrates, the shape of the projection surface of the groove 21 is an inverted trapezoid. Such a setting facilitates the assembly of the fixing member on the groove 21 and the assembly of the battery 6 in the fixing member.

[0046] Regarding the structure of the fixing member, in an alternative embodiment, the fixing member may specifically include a pair of fixing half-rings 41. On the opposite sides of the pair of fixing half-rings 41, connecting rods 42 are fixed. One end of the pair of connecting rods 42 away from each other passes through the through holes 43 on the groove 21 of the lifting platform 2 and extends to the outside. A locking member 44 is threadedly connected to the end of the connecting rod 42 extending to the outside. Such a setting can adjust the specific position of the hoop according to the actual size of the battery 6 to better adapt to batteries 6 of different sizes. In practical use, the battery 6 can be assembled in the two fixing half-rings 41, the two fixing half-rings 41 are butted together to fix the battery 6, and then the locking members 44 on the two connecting rods 42 are rotated in the approaching direction, and the two locking members 44 will abut against the outer sidewall of the lifting platform 2, finally realizing the fixation of the battery 6. The locking member 44 can specifically be a locking nut.

[0047] In other embodiments, the fixing member may specifically include a hoop, which has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.

[0048] In an alternative embodiment, the lifting platform 2 is configured to rise to a position height where the distance between the lifting platform 2 and the sprinkler is 30 cm - 50 cm after the battery 6 catches fire. With this setting, the distance between the lifting platform 2 and the sprinkler can be controlled within 30 cm - 50 cm. After multiple tests, the water flow sprayed at this distance is least likely to turn into water mist, making the fire-extinguishing water flow more concentrated.

[0049] For example, after the battery 6 catches fire, the distance between the position height to which the lifting platform 2 rises and the sprinkler can be 30 cm, 32 cm, 34 cm, 36 cm, 38 cm, 40 cm, 42 cm, 44 cm, 46 cm, 48 cm, 50 cm, etc. Of course, in some other embodiments, after the battery 6 catches fire, the distance between the position height to which the lifting platform 2 rises and the sprinkler can also be other values within the range of 30 cm - 50 cm.

[0050] Therefore, in summary, in view of the fire risk during acupuncture, a battery acupuncture test device is designed. The feature of this device is that the platform for conducting the acupuncture test also has a lifting function, which can enable the battery 6 to come into contact with the fire-extinguishing water flow faster, achieving the effect of extinguishing the fire in a timely manner; at the same time, the relatively short distance also avoids the atomization of the fire-extinguishing water flow. The inner wall surface of the hollow cavity 11 and the groove 21 of the lifting platform 2 can also make the water flow more concentrated, further improving the fire-extinguishing efficiency. At the same time, a thermal sensor can be specifically set to monitor whether there is a fire risk in the battery 6. With the action of the thermal sensor and the lifting platform 2, the operator does not need to face the burning battery 6, greatly improving safety; and this battery acupuncture test device can also make the fire-extinguishing water flow more concentrated and improve the fire-extinguishing efficiency.

[0051] To better understand the specific step process of this battery acupuncture test device, the following step process can be specifically referred to:

[0052] 1. The acupuncture experiment will be carried out on the lifting platform 2. Specifically, the battery 6 can be placed on the lifting platform 2. When conducting the acupuncture test, the needle tip of the test needle 5 will penetrate from the openings 12 at both ends of the cylindrical test body 1.

[0053] 2. After the acupuncture experiment is completed, there is a risk of fire. Therefore, the fire sprinkler 3 above will spray out a fire-extinguishing water flow containing a water-based fire-extinguishing material. At this time, the test needle 5 will be withdrawn, and at the same time, the lifting platform 2 will be activated and rise to a position height 30 cm - 50 cm away from the fire sprinkler. Due to the decrease in distance, the sprayed water flow is not easily turned into water mist, making the fire-extinguishing water flow more concentrated.

[0054] 3. The lifting platform 2 rises to a height exceeding the opening 12 of the test main body 1 and is located above the opening 12, so that a relatively sealed space is formed between the lifting platform 2 and the inner cavity wall of the hollow cavity 11, effectively preventing the loss of fire extinguishing water flow. At the same time, the groove 21 of the lifting platform 2 can also collect a certain amount of fire extinguishing water flow. After the fire extinguishing reaches a certain time, the battery 6 after acupuncture will be fully wetted, further improving the fire extinguishing efficiency.

[0055] 4. The fire extinguishing time is about 30 minutes to 1 hour. After the fire is extinguished, the lifting platform 2 is lowered, and the water flow will flow out from the openings 12 on both sides.

[0056] In summary, the battery acupuncture test device has the following beneficial effects for reference:

[0057] 1. It solves the problem that the operator needs to face the burning battery 6 directly, greatly improving safety.

[0058] 2. There is no need to make major modifications to the fire extinguishing sprinkler heads in the factory area. It is easy to disassemble. The fire extinguishing water flow under this device is not easily turned into water mist, and the fire extinguishing efficiency is higher. At the same time, under the action of the inner wall surface of the hollow cavity 11 and the groove 21 of the lifting platform 2, the utilization rate of the fire extinguishing water flow is further improved, further increasing the fire extinguishing efficiency.

[0059] 3. The lifting platform 2 and the cylindrical test main body 1 can make full use of the water flow, saving fire extinguishing materials.

[0060] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
