Movable type sandy-soil-throwing fire extinguishing device

Abstract

The invention discloses a movable type sandy-soil-throwing fire extinguishing device comprising a movable vehicle body, a sandy soil conveying mechanism and a control system. The control system and the sandy soil conveying mechanism are installed on the movable vehicle body. The sandy soil conveying mechanism comprises a feeding pipe, a discharging pipe, a material separator, an airlock and a draught fan. The material separator comprises a feeding opening, a discharging opening and an air outlet. The feeding opening communicates with the feeding pipe. The discharging opening communicates withthe discharging pipe through the airlock. The air outlet communicates with the air inlet of the draught fan. The control system comprises a controller, a vehicle body movement driving mechanism and asandy soil conveyance driving mechanism. The controller controls the movable vehicle body to move through the vehicle body movement driving mechanism. The controller controls the airlock and the draught fan in the sandy soil conveying mechanism to operate through the sandy soil conveyance driving mechanism, sandy soil materials are made to enter the movable type sandy-soil-throwing fire extinguishing device via the feeding pipe, sequentially pass through the material separator and the airlock and then flow out from the discharging pipe. The movable type sandy-soil-throwing fire extinguishing device can move, suck the sandy soil at a sand pile and blow out the sandy soil to cover a fire site, the fire extinguishing efficiency is high, and the safety of rescue workers can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of emergency rescue equipment, in particular to a mobile sand blasting fire extinguishing device. Background technique [0002] In the special fires that cannot be extinguished with water, foam, and carbon dioxide, such as sodium, potassium, calcium cyanide and other flammable solid hazardous chemical fires in contact with water and liquid flowing fires, sand and soil are often used to extinguish fires. Gas stations are equipped with sandboxes or sand ponds for fire prevention and containment. However, at present, the fire is usually extinguished by manual use of tools such as sand buckets and shovels to cover materials or by dumping and covering with construction machinery such as loaders. The fire extinguishing efficiency is low and the rescue risk is high. [0003] Patent No. CN200920254764.8 discloses a fire extinguishing sand truck for fire-fighting. Its body is provided with a bucket for loading sand,...

Problems solved by technology

This patent uses shock waves to throw sand and soil, and the device is equipped with an excavation mechanism for on-site soil retrieval. The throwing range is wide, and it is suitable for fire extinguishing in forests and grasslands. It is basically difficult to achieve, and the large throwing range not only reduces the local sand coverage and reduces the fire extinguishing efficiency, but also easily brings adverse effects on the surrounding environment of the fire site
