Firefighting sand box for battery fire extinction

Abstract

The invention relates to a firefighting sand box for battery fire extinction. The firefighting sand box comprises a box body, the box body is provided with an inner cavity for containing a battery anda door leaf for opening and closing the inner cavity, a sand plate for bearing firefighting sand is arranged on the upper portion of the inner cavity, sand leaking holes are formed in the sand plate,a sand leaking device is arranged below the sand plate, and the sand leaking device comprises a movable plate; and the movable plate is arranged on a movable support in an up-down movable mode, a spring is arranged between the movable plate and the movable support, elastic force of the spring upwards supports the movable plate, the movable support is connected with a driving mechanism, and the driving mechanism drives the movable support and the movable plate to enable the movable plate to move between the position where the sand leaking holes are blocked and the position where the sand leaking holes are opened. When the movable plate is located at the position where the sand leaking holes are blocked, firefighting sand at the edge of the sand leaking holes may enter or block a gap between the sand plate and the movable plate, and movement of the movable plate is hindered. At the moment, the movable plate can move downwards to compress the spring under the action of increased resistance of the firefighting sand, so that the distance between the movable plate and the sand plate is increased, and it is ensured that the movable plate can be opened smoothly all the time.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a fire-fighting sandbox for battery fire extinguishing. Background technique [0002] Due to the characteristics of battery combustion, compared with water, gas, dry powder and other fire extinguishing media, the method of covering the fire with sand has better fire extinguishing effect and higher safety. It can be used as the last line of defense for battery fire extinguishing treatment. For example, in a charging and swapping station, a large number of batteries are being charged and discharged at the same time. Once a battery catches fire, it is necessary to isolate and extinguish the fire immediately. The way to isolate the fire battery can be to isolate it in the charging and swapping station, or to transport the fire battery to the outside of the charging and swapping station, and use sand to cover the battery in the fire-fighting sandbox to exti...

AI Technical Summary

Problems solved by technology

Because the fire-fighting sand has been carried on the slip plate before the slip plate moves, the fire-fighting sand may be stuck between the slip plate and the upper plate during the movement of the slip plate, causing the slip plate and the upper plate to be stuck and unable to move. It is impossible to extinguish the fire on the battery, which delays the time to deal with the fire

Moreover, since the upper plate and the wrong leakage plate are all steel plates, the sand in each sand leakage hole may be stuck between the wrong leakage plate and the upper plate, causing the situation that the wrong leakage plate and the upper plate are stuck very easily, and , when multiple positions get stuck at the same time, it will increase the severity of the stuck, making it difficult to handle the stuck situation
