Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a water-immersed fire-extinguishing and explosion-proof platform for battery packs. Background Art

[0002] The battery pack market has broad prospects and high research value. Related test verification work is frequently carried out, most of which are destructive tests. During the test, there may be safety accidents such as battery pack leakage, fire, smoke, explosion, etc., which endanger the safety of life and property. In order to reduce the safety risks during the test, isolate the dangerous sources, and take relevant safety measures to protect the life and property of the test personnel and equipment;

[0003] A search of a Chinese patent with publication number CN212060507U disclosed a low-lying safety protection device for thermal diffusion testing of a battery pack.

[0004] The above technical solution includes a test rack, on which the battery pack is placed for a thermal diffusion test; the test rack is a liftable test rack, which is mounted on a lifting mechanism and rises and falls with the lifting of the lifting mechanism, and a sunken water pool is provided below the test rack below the ground level, and the test rack is lifted and lowered between the sunken water pool and the ground. The utility model conducts a thermal diffusion test on the battery pack through a lifting frame structure platform, and after the battery pack test is completed, the battery pack is sunk into the water pool, which can more safely achieve cooling, fire extinguishing, smoke extinguishing, and safety isolation of the battery pack;

[0005] However, in the above scheme, battery overload, fire and explosion often occur in an instant, which is instantaneous and unpredictable. The device immerses the battery pack in the coolant through a lifting device, which is very slow and highly dangerous. In particular, the impact force of the battery explosion will destroy the lifting structure, making it impossible for the battery to penetrate into the coolant to extinguish the fire. In addition, the impact force of the battery explosion may blow up the test rack, and there is a risk of the test rack blowing up and injuring people.

[0006] To this end, we proposed a battery pack immersion fire extinguishing and explosion-proof platform. Utility Model Content

[0007] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a battery pack immersion type fire extinguishing and explosion-proof platform.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme, a battery pack immersion fire extinguishing and explosion-proof platform, including a support platform, characterized in that: a water storage cylinder is fixedly connected under the support platform, a groove is opened in the support platform, the groove is connected to the water storage cylinder, and a fire extinguishing component is rotatably connected in the groove. The fire extinguishing component includes two support plates, and the support plates have a closed state and an open state. A rotating rod is fixedly connected to the side of the support plate, and the rotating rod is rotatably connected in the groove. A support rod close to the other support plate is also fixedly connected to one side of the support plate, and the support rod can be movably inserted in the limiting sleeve.

[0009] Preferably, two connection grooves are provided in the limiting sleeve, and support grooves are provided on both sides of the limiting sleeve. Right-angle plates are slidably connected in the support grooves, and the right-angle plates are fixedly connected under the support platform.

[0010] Preferably, the support platform is further provided with a mounting groove, in which a cylinder is fixedly connected, and an output end of the cylinder is movably connected to a gas rod, and the gas rod is fixedly connected to the limiting sleeve.

[0011] Preferably, an explosion-proof component is placed on the support plate, and the explosion-proof component includes a battery cage, and two evenly distributed extension plates are fixedly connected to the upper end of the battery cage.

[0012] Preferably, the extension plate is L-shaped, and an explosion-proof plate is fixedly connected between the two extension plates.

[0013] Preferably, a slide bar is fixedly connected to the lower end of the explosion-proof plate, and the slide bar is slidably connected in the slide groove.

[0014] Preferably, the slide groove is provided on the supporting platform, and a buffer gasket is provided outside the slide groove.

[0015] The utility model provides a battery pack immersion type fire extinguishing and explosion-proof platform, which has the following improvements and advantages compared with the prior art:

[0016] (1) The utility model adopts a limiting sleeve to control the opening and closing of the support plate. A water storage cylinder is fixedly connected to the lower part of the support platform. A slot is provided in the support platform, which is connected to the water storage cylinder. A fire extinguishing assembly is rotatably connected in the slot. The fire extinguishing assembly includes two support plates. The support plates have a closed state and an open state. A support rod is fixedly connected to the side of the support plate.

A right-angle plate is slidably connected in the support slot. The right-angle plate is fixedly connected to the lower part of the support platform. The platform is also provided with an installation groove, in which a cylinder is fixedly connected, and the output end of the cylinder is movably connected to a gas rod, which is fixedly connected to a limiting sleeve and inserted into the support rod through the limiting sleeve, so that the support plate is in a closed state. At this time, the battery pack can be subjected to an extreme test on the support plate. After the test is completed, the cylinder pulls the gas rod, and the gas rod pulls the limiting sleeve out of the support rod, the support rod loses support, and the support plate opens to both sides. The battery pack will fall directly into the water storage cylinder for cooling, and the battery pack can be quickly immersed in the coolant to reduce the risk of the battery pack being exposed to the outside.

The sliding rod is slidably connected in a sliding groove. The sliding groove is opened on the support platform. A buffer gasket is also arranged outside the sliding groove. By placing the explosion-proof component on the support plate, the battery cage slides into the coolant with the battery pack when the support plate is opened. The extension plate is arranged so that the battery cage can be completely immersed in the coolant. When the battery pack explodes, its impact force acts on the coolant. When the coolant dissipates, the impact of the impact force on the battery cage is reduced. The explosion-proof plate can block the coolant rushing upward, further reducing the impact of the battery pack explosion. The safety is very reliable. BRIEF DESCRIPTION OF THE DRAWINGS
