Sand throwing fire-extinguishing vehicle

Abstract

The invention discloses a sand throwing fire-extinguishing vehicle. According to the invention, a charging mechanism, a material-guiding mechanism and a feeding mechanism are arranged in a cargo compartment; the charging mechanism is arranged at the bottom of the cargo compartment, and form an enclosed cargo compartment body with peripheral parts of the cargo compartment, a base plate of the charging mechanism is movable, the material-guiding mechanism is arranged at an upper part of the base plate of the charging mechanism, the material-guiding mechanism realizes continuous forward propulsionwith the base plate, the feeding mechanism employs a spiral conveying form, and is arranged over the charging base plate at a rear part of the cargo compartment, the rotation direction of blades at left and right sides of a screw conveyer is opposite, materials at two sides are concentrated to center, and then are sent to a throwing mechanism, the throwing mechanism employs a centrifugal throwingmode, through high speed rotation of a throwing impeller, a throwing cylinder comprises a throwing straight tube, a throwing bend tube and a throwing head, the throwing bend tube is rotated at a horizontal plane, and a throwing angle of the throwing head can be adjusted. The sand throwing fire-extinguishing vehicle is capable of rapidly and continuously throwing solid fire-extinguishing materialssuch as dried sand and dried soil from a long distance to a fire district, and realizes high-efficiency fire-extinguishing.

Description

technical field [0001] The invention belongs to the technical field of emergency rescue, and in particular relates to a sand throwing train. Background technique [0002] In recent years, as the number of enterprises related to flammable and explosive dangerous goods in my country has continued to increase, the scale has continued to expand. The frequency and scale of fire and explosion accidents caused by hazardous chemicals during production, storage and transportation have also increased. Cause a large number of casualties, property loss and environmental pollution, bring immeasurable loss to the society. In the process of fighting fires involving hazardous chemicals, solid-state fire-extinguishing materials have played an inestimable role, especially for fires involving hazardous chemicals that avoid water, only solid-state fire-extinguishing materials can be used to fight fires. At present, the fire brigade is mainly equipped with water tanks and foam fire trucks, whi...

AI Technical Summary

Problems solved by technology

[0003] The existing technical scheme adopts the principle of pneumatic conveying to convey sand and soil, and the power loss of pneumatic conveying is large when conveying heavy materials, resulting in problems such as high energy consumption, short spray distance, small spray volume, and difficult adjustment of spray direction.
