It is mainly used to extinguish fires such as oil products and flammable chemicals. Currently, fire sand is generally stored in a fire sand box, and equipment such as a fire sand bucket and a spade are equipped beside the fire sand box.

[0003] Application No. 202021655632.9 discloses a sand storage device for fire extinguishing, which includes a sand storage box. An inlet is dug on one side of the top end of the sand storage box. A plurality of rotating shafts are rotatably connected to the top end inner wall of the sand storage box. A plurality of grooves are dug on the side walls of the plurality of rotating shafts. A cross bar movably penetrates through the inside of the sand storage box. A plurality of rings are fixedly sleeved in the middle of the side wall of the cross bar. The bottom ends of the plurality of rotating shafts are fixedly connected with dredging shafts. Sand discharge hoppers are fixedly embedded at positions corresponding to the bottom ends of the plurality of dredging shafts in the sand storage box. A bottom plate is arranged at the bottom of the sand storage box. The sand storage device for fire extinguishing of the utility model is provided with a plurality of sand discharge hoppers, which are matched with plug covers and a plurality of placement grooves, so that when sand is needed, sand can be synchronously discharged into a plurality of fire sand buckets, realizing the rapid extraction of fire sand, replacing the low efficiency of the traditional one-by-one filling, greatly improving the sand filling speed, winning time for rescue, and at the same time, there is no need for firefighters to shovel sand with a spade, reducing the labor intensity.
