Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a discharge testing device for lithium battery production. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Research on lithium-ion batteries has now begun. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become the mainstream.

[0003] For example, patent document CN 211669329 U discloses a lithium battery discharge detection device, including a fixed block. Detection lamps are evenly spaced along the horizontal direction within the inner cavity of the fixed block. A hollow detection box is fixedly connected to the bottom of the fixed block. An opening is provided on the front of the hollow detection box, and a fixing block is fixedly connected to the top of the opening at evenly spaced along the horizontal direction. A positive conductive block is fixedly connected to the side of the fixing block closest to the fixed block. This invention, through the structural design between the second sliding groove, the first sliding block, and the first return spring, allows the first sliding block to slide back and forth within the second sliding groove, thereby allowing the movable fixing block to slide back and forth within the groove. This enables the lithium battery discharge detection device to detect lithium batteries of different lengths, thus achieving the goal of simultaneously detecting multiple lithium batteries of different specifications.

[0004] However, in actual use, due to its structural limitations, this structure can only perform simple open-type lithium battery production discharge detection. When an accidental explosion of a lithium battery is detected, it cannot extinguish the fire immediately, which will continue to burn the discharge detection equipment, resulting in greater losses. At the same time, the equipment cannot properly filter the exhaust gas generated when the lithium battery explodes, which cannot meet the needs of daily use. Therefore, it is urgent to design a lithium battery production discharge detection device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lithium battery production discharge detection device to solve the problem mentioned in the background art. In actual use, due to the limitations of its own structure, the existing structure can only adopt a simple open-type lithium battery production discharge detection. When the detection of an accidental explosion of a lithium battery occurs, it is impossible to extinguish the fire of the battery in time, which will continue to burn the discharge detection device and cause greater losses. At the same time, the device cannot properly filter the exhaust gas generated when the lithium battery explodes, and cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery production discharge testing device, comprising a storage tank, with limiting side frames fixedly connected to both sides of the storage tank, a testing component provided at the top of the storage tank, and an exhaust component provided at the top of the testing component.

[0007] The detection assembly includes a detection box, which is movably connected to the top of the liquid storage tank, and the inner wall of the detection box is provided with a detection groove;

[0008] The exhaust assembly includes a top cover, the top of which is movably connected to the top of the detection box, and a movable shaft is provided between the detection box and the top cover.

[0009] Preferably, a sealing ring is provided between the testing box and the top cover.

[0010] Preferably, an exhaust fan is provided inside the top cover, and an air filter seat is provided at the bottom of the exhaust fan.

[0011] Preferably, the side of the testing box is provided with a seepage hole groove, and the two sides of the testing box are fixedly connected with a limiting slide plate.

[0012] Preferably, the bottom of the testing box is provided with a support slot, and a support bracket is movably connected inside the support slot.

[0013] Preferably, a contraction airbag is provided at the bottom front end of the support bracket, and a limit slide is fixedly connected to the top front end of the support bracket.

[0014] Preferably, a liquid control seat is fixedly connected to the bottom of the liquid storage tank, and liquid control valve seats are provided at both ends of the liquid control seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This lithium battery production discharge testing equipment, through its designed storage tank, limiting side frame, testing box, testing tank, seepage hole tank, limiting slide plate, support bracket, shrinkage airbag, and limiting slide, makes the equipment safer and more capable of handling emergencies during lithium battery discharge testing. In actual use, the operator first places the lithium battery into the testing box, assembles the power generation wire, and then the lithium battery can undergo discharge testing inside the testing box. If a battery combustion problem occurs during the testing process, the shrinkage airbag can be activated to prevent the battery from burning. The support bracket is moved out from the support slot at the bottom of the testing box. The limiting slide at the top front of the support bracket slides against the surface of the liquid storage tank. After the testing box is supported, it is quickly inserted into the liquid storage tank. The limiting slide plates on both sides of the testing box can slide at the limiting side frames on both sides of the liquid storage tank. Then, the specially made lithium battery fire extinguishing solution inside the liquid storage tank quickly enters through the seepage hole groove of the testing box. In conjunction with the testing groove on the inner wall of the testing box, the lithium battery is completely immersed for rapid fire extinguishing treatment, demonstrating the practicality of the equipment design.

[0017] This lithium battery production discharge testing equipment, through its integrated components including a storage tank, testing chamber, top cover, movable shaft, sealing ring, exhaust fan, and filter seat, further enhances the overall usability of the equipment. During daily use, operators can connect and close the top cover to the top of the testing chamber via the movable shaft, and then seal the connection using the sealing ring between the testing chamber and the top cover. The exhaust fan inside the top cover, in conjunction with the filter seat at the top, performs filtration and exhaust operations during the combustion of lithium batteries inside the testing chamber, ensuring the safety of the gas pressure inside the storage tank. This demonstrates the comprehensiveness of the equipment design. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A lithium battery production discharge testing device includes a storage tank 1, with limiting side frames 2 fixedly connected to both sides of the storage tank 1. A testing component is installed at the top of the storage tank 1, and an exhaust component is installed at the top of the testing component. A support slot 12 is opened at the bottom of the testing chamber 3, and a support seat 13 is movably connected inside the support slot 12. A contraction airbag 14 is installed at the bottom front of the support seat 13, and a limiting slide 15 is fixedly connected to the top front of the support seat 13. A liquid control seat 16 is fixedly connected to the bottom of the storage tank 1, and liquid control valve seats 17 are installed at both ends of the liquid control seat 16. A specially made lithium battery fire extinguishing solution is quickly introduced into the storage tank 1 through the seepage hole 10 of the testing chamber 3, and in conjunction with the testing groove 4 on the inner wall of the testing chamber 3, the lithium battery is subjected to a complete immersion-type rapid fire extinguishing treatment.

[0027] The detection assembly includes a detection box 3, which is movably connected to the top of the liquid storage tank 1. The inner wall of the detection box 3 is provided with a detection groove 4. The exhaust assembly includes a top cover 5, which is movably connected to the top of the detection box 3. A movable shaft 6 is provided between the detection box 3 and the top cover 5. A sealing ring 7 is provided between the detection box 3 and the top cover 5. An exhaust fan 8 is provided inside the top cover 5. A filter seat 9 is provided at the bottom of the exhaust fan 8. A seepage hole groove 10 is provided on the side of the detection box 3. Limiting slide plates 11 are fixedly connected to both sides of the detection box 3. The top cover 5 is closed by connecting it to the top of the detection box 3 via the movable shaft 6 and sealed by the sealing ring 7 between the detection box 3 and the top cover 5. Then the exhaust fan 8 inside the top cover 5 can be started, which, together with the filter seat 9 at the top, performs the filtration and exhaust operation when the lithium battery inside the detection box 3 is burning.

[0028] Working principle: During use, the user first places the lithium battery into the testing box 3. After assembling the power generation wires, the lithium battery can then undergo discharge testing inside the testing box 3. If a battery combustion problem occurs during the testing process, the user can control the activation of the contraction airbag 14, causing it to move the support bracket 13 out of the support slot 12 at the bottom of the testing box 3. The limiting slide 15 at the top front of the support bracket 13 slides against the surface of the liquid storage tank 1. After the testing box 3 provides support, it quickly plunges into the liquid storage tank 1. The limiting slide plates 11 on both sides of the testing box 3 can slide at the limiting side frames 2 on both sides of the liquid storage tank 1. The specially formulated lithium battery extinguishing solution inside the storage tank 1 is quickly introduced into the seepage groove 10 of the detection box 3. Combined with the detection groove 4 on the inner wall of the detection box 3, the lithium battery is completely immersed for rapid fire extinguishing. In daily use, the operator can connect and close the top cover 5 to the top of the detection box 3 via the movable shaft 6, and seal the connection between the detection box 3 and the top cover 5 with the sealing ring 7. Then, the exhaust fan 8 inside the top cover 5 can be started, and in conjunction with the air filter seat 9 at the top, the filtration and exhaust operation is carried out in case of combustion of the lithium battery inside the detection box 3, ensuring the air pressure safety inside the storage tank 1. The above is the complete working principle of this utility model.
