Example Embodiment

[0013] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings; it should be noted that the embodiments are descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0014] A power battery fireproof drag chain device includes an iron chain 1, a fireproof cloth 2, a left fixing ring 4 and a right fixing ring 3, wherein the left fixing ring and the right fixing ring are both metal rings. The right fixing ring is installed in the middle of the iron chain, one end of the iron chain passes through the left fixing ring and extends out a left extension section, and the other end of the iron chain passes through the left fixing ring and the right fixing ring in turn and extends outward. A right side extension section is formed, and the fireproof cloth is installed on the iron chain, the left fixing ring and the right fixing ring, and the fireproof cloth, the iron chain, the left fixing ...

Abstract

The invention relates to a fireproof drag chain device of a power battery. The fireproof drag chain device comprises an iron chain, fireproof cloth, a left fixed ring and a right fixed ring, wherein the right fixed ring is arranged at the middle part of the iron chain in a penetrating manner; one end of the iron chain passes through the left fixed ring and extends out of a left side extension segment outwards and the other end of the iron chain sequentially passes through the left fixed ring and the right fixed ring and extends out of a right side extension segment outwards; the fireproof cloth is arranged on the iron chain, the left fixed ring and the right fixed ring; and the fireproof cloth, the iron chain, the left fixed ring and the right fixed ring form a fireproof occlusion region. The fireproof drag chain device of the power battery is ingenious in design, reasonable in structure and flexible and convenient to use; by the device, the treatment efficiency can be improved, the treatment effect is ensured, accident diffusion is avoided and the personnel and property safety is ensured; and the fireproof drag chain device is especially suitable for promotion and application in the occasions of an electric vehicle swap station and the like.

Description

technical field [0001] The invention relates to the technical field of emergency treatment of an electric vehicle swapping station, in particular to a power battery fireproof drag chain device. Background technique [0002] At present, the power batteries of electric vehicles are mainly lithium-ion batteries, and lithium-ion batteries are active in nature. Once a violent reaction occurs, traditional fire extinguishers cannot be used to prevent combustion. Therefore, when a box of batteries spontaneously ignites due to drop, short circuit or other reasons, it may also have adverse effects on other batteries. It must be transferred immediately and buried to prevent the accident from spreading. [0003] Because lithium-ion batteries will be accompanied by smoke, acid spray, and flash explosions when they react violently, emergency personnel may not be able to get close to the batteries. In the electric vehicle replacement station or other places, the power battery in an emerge...
