Description

Roof fire fighting device

Technical Field

The invention relates to the technical field of fire safety, in particular to a roof fire fighting device.

Background

With the progress of building technology and the rapid development of cities, the number of high-rise buildings is more and more, once a fire disaster occurs, the fire fighting problem of the high-rise buildings becomes the key in the prior art.

According to incomplete statistics, large-scale fire disasters of high-rise buildings are mostly firstly caused indoors, then outer wall bodies are ignited, the fire disasters are easy to burn due to the fact that heat insulation materials are contained in the outer walls, and the fire disasters are spread to the whole building from the outer walls, so that other floors are affected, once the fire disasters are caught, and the fire disasters are difficult to control through the existing fire fighting technology.

Example 1: 1 month and 1 day in 2020, a 30-storey residential building in Chongqing has a fire, the fire originates from an indoor ignition outer wall body, the fire rapidly spreads the whole building from top to bottom, and 38 fire trucks are in the fire-fighting field.

Example 2: in 2011, 2, 3 days, the Shenyang Huang of the first highest in the northeast takes place a big fire in Wanxin hotel, the building is composed of three tower buildings, the height of a main building A is up to 219 meters, the height of an B, C seat is up to 152 meters, the fire spread to the whole building along the outer wall body, and in the case of the super high-rise building, the height of a water spray gun is limited, the fire at the high position cannot be controlled, and even if a large number of fire trucks arrive in time, the fire cannot be controlled.

At present, the fire extinguishing height of most fire trucks is about 50 meters, the number of aerial ladder fire trucks about 100 meters is lower than 10 domestically, the aerial ladder fire trucks in the world are only 113 meters, and the left-right swinging amplitude of a platform with the height of about 100 meters of the unfolded fire truck is about 2 meters under breeze, so that the requirement on the psychological quality of firemen is extremely high, and the spraying difficulty of fire extinguishing agents is very high.

Based on the above, we invented a roof fire fighting device.

Referring to fig. 3, fire extinguishing systems, dolly (3) are located ring carrier (2), and the belly is equipped with fire-fighting lance (4) and passes through welded fastening, aims at building body outer wall, establishes independent driving system in dolly (3) and can be the seesaw along ring carrier (2) to adjust the angle with the building body, and then adjust the spray angle of fire-fighting lance (4) in order to be applicable to the fire extinguishing of different floor heights, provide the water source by water tank (1), realize 360 degrees no dead angles operations of putting out a fire.

The invention has the beneficial effects that: the roof fire fighting device has quick response and can spray water to extinguish fire under the condition that the fire is not spread; the device is arranged on the roof, breaks through the limit on the height of fire rescue, does not need manual control, and ensures the safety of fire fighters to a certain extent; the fire-fighting lance (4) can move to any direction of a building along the slideway (5), and the spraying angle of the fire-fighting lance (4) can be adjusted, so that a fire disaster occurring at any floor height can be controlled; the invention is provided with an independent power supply system, and the fire fighting equipment can also work normally under the condition of power failure of a building.
