Problems solved by technology

[0004] The above methods are mainly air supply to prevent smoke and negative pressure smoke exhaust, that is, to use positive pressure air supply to prevent smoke from entering the evacuation channel, or to accelerate the discharge of smoke from the negative pressure smoke exhaust port, and even under certain unfavorable conditions, the airflow changes It may also lead to the effect of wind aiding the fire, and the smoke itself does not decrease during the whole process. The existence of smoke will adversely affect the life safety of firefighters and the fire fighting ability

Embodiment 1

[0032] see figure 2 , a fire-fighting smoke removal device, comprising a directional blowing device, a negative ion generator, and an air guiding device connected in sequence. The fire-fighting and smoke removal device is a portable device, and also includes wearing equipment, and the wearing equipment is fixedly connected to at least one of the directional blowing device, negative ion generator, and wind guiding device. This connection of the wearing equipment is conceivable out, the accompanying drawings do not show this in detail, and will not be repeated here.

[0033] In this embodiment, the wearing equipment may be a harness.

[0034] The fire-fighting and smoke-removing device composed of directional blowing device, negative ion generator and air-guiding device is used for fire-fighting and dust-removal.

Embodiment 2

[0036] see image 3 , a fire-fighting smoke removal device, comprising a directional blowing device, a negative ion generator, and an air guiding device connected in sequence. It also includes a suction fan from top to bottom, the lower part of the suction fan is aligned and close to the smoke particle collector, the side of the smoke particle collector is connected with the mobile chassis, the upper part of the mobile chassis is connected with the hollow device rod, and the upper end of the device rod is connected with the device rod. The directional blowing device is connected; the device rod can be adjusted up and down.

[0037] In this embodiment, the fire-fighting and smoke removal device is a robot device, and the follow-up robot device has a smoke sensor and a controller, and the controller is respectively connected to the smoke sensor and the power device of the mobile chassis for signal connection. The position of the smoke is automatically sensed by the smoke sensor...

Embodiment 3

[0040] see image 3 with 4 , a fire-fighting smoke removal device, comprising a directional blowing device, a negative ion generator, and an air guiding device connected in sequence. It also includes a suction fan from top to bottom, the lower part of the suction fan is aligned and close to the smoke particle collector, the side of the smoke particle collector is connected with the mobile chassis, the upper part of the mobile chassis is connected with the hollow device rod, and the upper end of the device rod is connected with the device rod. The directional blowing device is connected. The fire-fighting and smoke removal device is a diffuser device, which uses chains to connect multiple mobile chassis, and the air guide devices above each mobile chassis are directed upwards, so that negative ions diffuse to high places.

[0041] In this embodiment, the position of the smoke is automatically sensed by the smoke sensor and fed back to the controller, and the controller contro...

Abstract

The invention relates to a fire-fighting facility, in particular to a fire-fighting and smoke removing method and device. The fire-fighting and smoke removing device comprises a directional air blowing device, an anion generator and an air guide device which are sequentially connected with one another. The fire-fighting and smoke removing device can be a portable device and can also be of an air guide structure for supporting, moving and guiding air at the same time; meanwhile, the tail end of the air guide structure is provided with an air suction fan capable of sucking air from top to bottom; and the lower part of the air suction fan is provided with a smoke particle collector. By adopting the fire-fighting and smoke removing device, the effect of fire-fighting and smoke removal is remarkably improved; by means of a wearing type, a throwing type and a robot automatic walking manner, the convenience, the rapidness and the effectiveness of fire-fighting and smoke removal are improved;and the life safety of firefighters is guaranteed, and the fire-fighting ability of the firefighters is improved.

Description

technical field [0001] The invention relates to a fire-fighting facility, in particular to a fire-fighting and smoke-removing method and device. Background technique [0002] Smog is the number one killer in fires. According to relevant statistics, those who died of suffocation due to carbon monoxide poisoning or were suffocated by other toxic smoke generally accounted for 40% to 50% of the total number of fire deaths, and among the people who were burned to death, most He was burnt to death after being poisoned and suffocated. Smoke is a mixture of gaseous, liquid and solid substances and air containing a large amount of heat generated by the thermal decomposition of substances in the process of combustion reaction. It is composed of extremely small carbon black particles completely burned or incompletely burned ash and other combustion decomposition of combustibles Composed of products, in addition to the hazards of high temperature and toxicity, smoke will also greatly a...
