Automatic rising and falling wind resistance high pressure fine water mist fire extinguishing device

Abstract

The invention relates to an automatic rising and falling wind resistance high pressure fine water mist fire extinguishing device. The automatic rising and falling wind resistance high pressure fine water mist fire extinguishing device comprises a lifting mechanism and a fire extinguishing spraying head. The lifting mechanism comprises a main water tube, branched water tubes, a T-shaped three-way tube, a spring and a water storage tank, the main water tube is rotatably connected to the two ends of the T-shaped three-way tube in the horizontal direction in a sealing mode, one ends of the branched water tubes are connected with one end of the T-shaped three-way tube in the longitudinal direction, the fire extinguishing spraying head is connected to the other ends of the branched water tubes,the water storage tank is arranged on the branched water tubes, and the branched water tubes are connected with the top of a space in which a connecting device is located through the spring. The fireextinguishing spraying head comprises a rotational flow pressurizing module and a spray nozzle module, the rotational flow pressurizing module comprises a tangential slot unit and a direct incidence interception unit, the tangential slot unit is arranged in the branched water tubes and connected to the mounting end, and the direct incidence interception unit is arranged in the branched water tubesand connected with the tangential slot unit. Compared with the prior art, the automatic rising and falling wind resistance high pressure fine water mist fire extinguishing device can perform efficient fire extinguishing when fire disaster occurs in a perpendicular state; and efficient fire extinguishing further can be carried out in a windy environment, and the good integral fire extinguishing performance is guaranteed.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to an automatic rising and falling anti-wind and high-pressure fine water mist fire extinguishing device. Background technique [0002] As a new fire extinguishing system, the high pressure water mist fire extinguishing system has been widely used in the field of fire protection. Water mist nozzle is an important part of water mist fire extinguishing system, and its good atomization performance is the guarantee of fire extinguishing efficiency. However, in some semi-open large indoor spaces, once a fire breaks out, strong crosswinds are likely to occur. Traditional fine water mist nozzles have a small atomization angle and are easily blown away by the wind, resulting in low fire extinguishing performance. Moreover, for a semi-open large indoor space, because of its high floor height, the existing fire extinguishing nozzles at a relatively high level will reduce the efficiency of fire ...

However, in some semi-open large indoor spaces, once a fire breaks out, strong crosswinds are likely to occur. Traditional nozzles with traditional fine water mist nozzles have a small atomization angle and are easily blown away by the wind, resulting in low fire extinguishing performance.

Moreover, for a semi-open large indoor space, because of its high floor height, the existing fire extinguishing nozzles at a higher level will reduce the efficiency of fire extinguishing
