Sand throwing fire extinguishing device for gas station

Abstract

The invention provides a sand-throwing fire extinguishing device for a gas station, which effectively solves the problem that the fire-fighting sand in the existing sand-throwing device is scattered when it falls, and it takes a long time to suppress the fire, and the burning objects cannot be isolated instantaneously. The problem of not being able to prevent the fire from spreading in time; the technical solution is to include a cylinder with a material storage box on the left end of the cylinder, a rotating shaft inside the cylinder, a raised strip on the rotating shaft, and a rotating shaft that can rotate with it. Helical blade, there is a card slot on the helical blade, and the protruding strip is stuck in the card slot. The helical blade can be stretched in the left and right directions, and the sleeve is set on the rotating shaft. There are rectangular boxes on both sides, and each rectangular box has a baffle; there is a shell on the right side of the cylinder, and a discharge port is opened on the side wall of the shell. The right end of the cylinder runs through the side wall of the shell, and the shell can wrap around the cylinder. When rotating, there is a hollow cylinder coaxial with the rotating shaft in the casing, and a plurality of blades uniformly distributed around the circumference are arranged on the hollow cylinder to form an impeller.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing devices, in particular to a sand throwing fire extinguishing device for gas stations. Background technique [0002] Fire-fighting sand is generally medium-coarse dry yellow sand, which is placed in a fire-fighting bucket and used to extinguish oil fires. It is an important part of the fire-fighting system of gas stations. The existing fire-fighting sand is generally equipped in a specific place. When using it, open the fire-fighting sandbox and manually use a shovel or a trolley to throw sand towards the fire point. Inflammable and explosive characteristics, this method has obvious defects, the most important is that the personal safety of firefighters is threatened, and the fire extinguishing efficiency is low. [0003] There are also a small number of special fire-fighting trucks that use sand throwing. The impeller and the auger of the throwing system are mainly rigidly connected an...
