Fire-fighting sandbox opened by rocker arm in inclined mode
Technical Field
The invention relates to the technical field of fire fighting equipment, in particular to a fire fighting sandbox with an obliquely opened rocker arm.
Background
A fire fighting sandbox is a facility which is specially used for fighting fire in oil filling equipment such as a main transformer, a reactor and the like and oil and gas places. The fire-fighting sandbox is a necessary fire-fighting apparatus for oil depots (diesel oil and lubricating oil), canteen kitchens, repair workshops which often fire and the like.
Normally, because oils cannot be extinguished with water. When emergent fire fighting, the staff removes the top apron of opening the fire control sandbox earlier, opens box upper portion for dry sand flows by gravity by oneself, and later, staff's reuse spade transports the conflagration department by the fire control sandbox to the sand, and covers the sand on oil or flammable liquid, puts out a fire through the effect of suffocating, thereby eliminates the conflagration.
However, with the existing technical solutions, the efficiency of fire extinguishing is not high.
