Description

Technical Field

[0001] The utility model relates to the technical field of experimental devices, in particular to an experimental device for extinguishing lithium-ion battery fires using perfluorohexanone. Background Art

[0002] Lithium-ion batteries have been widely used in portable electronic devices, electric vehicles, and energy storage systems due to their high energy density, long life, and low self-discharge rate. However, lithium-ion batteries are prone to thermal runaway reactions in the event of abuse, overcharging, short circuits, or internal defects, causing the battery temperature to rise sharply, and even causing fires or explosions. Perfluorohexanone, as a clean and efficient fire extinguishing agent, can quickly reduce the fire temperature and suppress the spread of flames in a short period of time. At the same time, its low toxicity and low residual properties are also in line with the green development trend of modern firefighting technology. Perfluorohexanone has shown excellent fire extinguishing effects in lithium-ion battery fires. It has a fast fire extinguishing speed and high fire extinguishing efficiency, and does not cause long-term harm to the environment and human body. Therefore, perfluorohexanone automatic fire extinguishing devices have broad application prospects and promotion value in the field of lithium-ion battery fire prevention and control.

[0003] Currently, when using perfluorohexanone fire extinguishing agent to conduct fire extinguishing experiments on lithium-ion batteries, the existing experimental equipment cannot adjust the nozzle position according to the position where the lithium-ion battery is loaded on the vehicle. In addition, due to the inconsistent chassis heights of different vehicles, it is impossible to adjust the actual simulated chassis height to match the actual spray angle for testing, making it difficult to accurately measure experimental data. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that it is impossible to synchronously simulate the fire extinguishing of lithium-ion battery usage scenarios, and to propose a perfluorohexanone lithium-ion battery fire suppression experimental device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A perfluorohexanone experimental device for suppressing lithium-ion battery fires comprises a waste tank and two brackets fixedly connected to the waste tank, wherein a slider is slidably mounted in the bracket, a mounting frame is rotatably mounted on the slider, and a shunt pipe rotatably mounted on the waste tank, wherein a plurality of nozzles are fixedly connected to the shunt pipe, and the mounting frame is provided with an adjustment portion for pulling the nozzles to rotate.

[0007] Preferably, a sliding groove is provided on the bracket, the slider is slidably installed in the sliding groove, a connecting rod is rotatably installed on the slider, and the mounting bracket is fixedly connected to the connecting rod.

[0008] In order to adjust the height of the lithium-ion battery, preferably, the connecting rod on one side passes through the bracket, and a pull plate is fixedly connected to the connecting rod, a top rod is fixedly connected to the pull plate, a pressure plate is fixedly connected to the top rod, and a plurality of limit grooves are arrayed on the bracket, and the pressure plate cooperates with the limit grooves.

[0009] In order to clamp the lithium-ion battery, a clamping plate is slidably mounted on the mounting frame, a telescopic slot is provided on the mounting frame, a limiting rod is fixedly connected to the clamping plate, and the limiting rod is slidably mounted in the telescopic slot.

[0010] In order to provide the clamping force, further, the limiting rod is fixedly connected to a limiting block, the limiting block is fixedly connected to a return spring, and the free end of the return spring is fixedly connected to the telescopic slot.

[0011] In order to drain the perfluorohexanone liquid, further, both ends of the diversion pipe are fixedly connected to a rotating shaft, the rotating shaft is rotatably installed on the waste trough, the waste trough is fixedly connected to a liquid storage tank, the liquid storage tank is fixedly connected to a water outlet pipe, and the water outlet pipe is fixedly connected to the diversion pipe.

[0012] In order to adjust the nozzle angle, further, the adjustment part includes a rotating plate rotatably mounted on the connecting rod, a pull rod is rotatably mounted on the rotating plate, a fixing sleeve is slidably mounted on the nozzle, and the fixing sleeve is fixedly connected to the pull rod.

[0014] Compared with the prior art, the present invention provides a perfluorohexanone-based lithium-ion battery fire extinguishing experimental device, which has the following beneficial effects:

[0015] 1. The perfluorohexanone lithium-ion battery fire suppression experimental device, through the design of the adjustment part, synchronously adjusts the nozzle angle according to the different chassis heights of the battery simulation car, simulating the fire conditions of lithium-ion batteries in different scenarios, ensuring that perfluorohexanone can be sprayed to the fire source. Due to the characteristic that perfluorohexanone will vaporize rapidly after spraying, it absorbs a large amount of heat during the vaporization process, causing the fire source temperature to drop rapidly, thereby suppressing the combustion of the flame, obtaining more reliable experimental data, and accurately testing the suppression effect of perfluorohexanone fire extinguishing agent.

[0016] 2. The perfluorohexanone lithium-ion battery fire suppression experimental device allows the height of the lithium-ion battery to be flexibly adjusted through the slider and limit rod design in the device to meet the simulation requirements of the chassis height of different vehicle models, thereby improving the applicability and accuracy of the experiment.

[0017] 3. The perfluorohexanone fire suppression experimental device for lithium-ion batteries uses a destruction cone to allow experimenters to perform physical destruction. By pulling the handle, the destruction cone punctures the lithium-ion battery, simulating a fire caused by a collision with the car chassis, in order to test the fire extinguishing effect of the perfluorohexanone fire extinguishing agent.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented using the prior art. The utility model can accurately simulate the fire extinguishing effect of perfluorohexanone on cars with different chassis heights and battery positions when they catch fire, thereby obtaining more reliable experimental data.
