A fire-fighting sandbox for battery fire-fighting

Abstract

The invention discloses a fire-fighting sandbox for battery fire-fighting, which comprises a box body, the box body is provided with an inner chamber for accommodating batteries and a door leaf for switching the inner chamber, a sandboard for carrying fire-fighting sand is arranged on the upper part of the inner chamber, and the sandboard There is a sand leakage hole, and a sand leakage device is provided under the sand board. The sand leakage device includes a movable plate, which can be moved up and down on the movable support. A spring is arranged between the movable plate and the movable support, and the elastic force of the spring supports it upwards. The movable plate and the movable support are connected with a driving mechanism, and the driving mechanism drives the movable support and the movable plate, so that the movable plate can move between the positions of blocking and opening the sand leakage hole. When the movable plate is at the position of blocking the sand leakage hole, the fire-fighting sand at the edge of the sand leakage hole may enter or block the gap between the sand plate and the movable plate, hindering the movement of the movable plate. At this time, the movable plate will move downward under the increased resistance of the fire-fighting sand to compress the spring, thereby increasing the distance between the movable plate and the sand plate, and ensuring that the movable plate can always be opened smoothly.

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
