Description

Technical Field

[0001] This utility model relates to the technical field of emergency protection devices for offline debugging, specifically an emergency protection device for lithium battery offline debugging. Background Technology

[0002] Power batteries are one of the most important components of new energy vehicles, directly determining their performance, cost, stability, and lifespan. Therefore, before mass production and installation, their condition is tested and verified by power-on debugging and durability testing. However, unverified power batteries may pose safety hazards during assembly quality or power-on debugging and performance verification. Therefore, safety devices are installed and tools are placed before power-on debugging and testing begin.

[0003] Existing safety devices and tools require at least two people to manually operate multiple devices in the event of an accident, and there is no effective fire extinguishing and isolation device. Although they can effectively solve safety accidents, since the tests are not always conducted by the same two people, when a sudden accident occurs, the manual operation by multiple people inevitably leads to poor coordination. In addition, manual accident operations are risky, and the space of the testing environment is limited. Installing a series of safety devices is not only costly, but also requires a large area. Utility Model Content

[0004] The purpose of this utility model is to provide an emergency protection device for lithium battery offline debugging, so as to solve the problems mentioned in the background art that the emergency protection device for offline debugging is not convenient for classifying and extinguishing different types of lithium batteries, not convenient for rapid and efficient fire extinguishing, not convenient for quickly cutting off the lithium battery cable and disconnecting it from the test equipment, and not convenient for suppressing and eliminating sudden accidents more quickly, accurately and safely in the event of a sudden accident during the test, thus affecting the safety of fire extinguishing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency protection device for lithium battery offline debugging, comprising an isolation chamber and a nozzle. A support frame is provided outside the isolation chamber, and a support bracket is provided on the side of the isolation chamber away from the support frame. A water tank bracket is provided outside the isolation chamber on one side of the support frame. A carbon dioxide tank is provided inside the support bracket. A battery debugging platform is provided inside the isolation chamber. Two sets of bosses are installed inside the isolation chamber below the battery debugging platform.

A first solenoid valve is installed inside the water tank bracket. A nozzle is installed at the top of the isolation chamber above the battery debugging platform, extending into the interior of the isolation chamber. A second solenoid valve is installed at the top of the carbon dioxide tank.

[0006] Preferably, a hose is installed on the outer wall of the second solenoid valve, and the hose extends into the interior of the nozzle.

[0007] Preferably, a battery harness is installed on the outer wall of the tester, and a harness hole is provided inside the isolation chamber on one side of the H-shaped fixture, and the battery harness extends through the H-shaped fixture and the harness hole to the interior of the battery test bench.

[0008] Preferably, a nozzle is installed on the inner wall of the isolation chamber on one side of the wire harness hole, and an extended water pipe is installed on the outer wall of the first solenoid valve, with the extended water pipe extending into the interior of the nozzle.

[0009] Preferably, the inside of the H-shaped tooling is symmetrically equipped with slides, and a guillotine is installed between the two sets of slides.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the emergency protection device for offline debugging not only realizes the classification and fire extinguishing of different types of lithium batteries, which facilitates rapid and efficient fire extinguishing and facilitates the quick cutting and disconnection of lithium battery cables from the test equipment, but also facilitates the faster, more accurate and safer suppression and elimination of sudden accidents during the test, thus improving the safety during fire extinguishing.

[0014] When the lithium battery placed is a non-power battery and catches fire during testing, the carbon dioxide inside the carbon dioxide tank enters the inside of the nozzle through the hose and is ejected by the nozzle to extinguish the lithium battery inside the battery debugging table. When the lithium battery is a power battery, water enters the inside of the nozzle through the extended water pipe and the nozzle sprays water to extinguish the fire. When the fire is relatively serious, the cylinder drives the tool handle and the guillotine to move downward, and the guillotine cuts off the battery wiring harness. Open the door panel, place the forklift fork plate on one side of the convex platform, and fork out the battery debugging table to a空旷 area for fire extinguishing. The lithium battery offline debugging emergency protection device classifies and extinguishes different types of lithium batteries, facilitating fast and efficient fire extinguishing, quickly cutting off the lithium battery cable and detaching it from the testing equipment, and enabling faster, more accurate, and safer suppression and elimination of sudden accidents during the test, improving the safety during fire extinguishing.
