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

Embodiment 1

[0036]In the present invention, the control system can be realized by using the existing micro-controller. The material separator, the air shutoff device and the blower fan are all existing mature products. The blades in blowers and blowers rotate. The sand transmission driving mechanism can adopt the cooperation of the motor and the transmission wheel shaft, which is prior art, so the microcontroller realizes the operation control of the air shutoff device and the blower fan through the sand transmission driving mechanism.

[0037] The mobile drive control of the car body is also a prior art. The motor, diesel engine or gasoline engine can also be used as the power source in the moving drive mechanism of the car body.

[0038] There is also a dust collector 605 between the air outlet of the material separator and the air inlet of the fan. The air inlet of the dust collector is connected to the air outlet of the material separator through a connecting pipe 604 , and the air o...

Embodiment 2

[0048] In this embodiment, the discharge pipe includes a fixed pipe and a movable pipe. The fixed pipe is fixedly installed on the vehicle frame. One end of the fixed pipe is connected to the discharge port of the air locker and the air outlet of the fan, and the other end is detachably connected to the movable pipe. The fixed pipe of the discharge pipe is a hard pipe made of wear-resistant material, and the movable pipe is made of silicone or rubber hose.

Embodiment 3

[0050] During concrete implementation, the present invention is made up of movable vehicle body, control system, power system, transmission system and sand and earth conveying mechanism.

[0051] The power system is the power source, which is installed on the top of the vehicle frame and can adopt diesel, gasoline engine or electric motor. The transmission system is connected with the power system, and can adopt the form of mechanical transmission, hydraulic transmission or electric transmission to realize the driving of the wheels, as well as the driving of the air shutoff device and fan in the sand and soil transmission mechanism. If a diesel engine and mechanical transmission are used, the power from the engine is transmitted through the transmission shaft, and part of the power is transmitted to the walking system through the transfer case and the transmission shaft. Part of the power is transmitted to the sand and soil conveying mechanism through the transfer case, transm...

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,...
