Description

Technical Field

[0001] The utility model relates to the field of fire protection, in particular to an emergency fire extinguishing system for the exterior wall of a high-rise building. Background Art

[0002] When a fire occurs on the facade of a high-rise building, the fire will spread upward, forming a clear "chimney effect". At the same time, combustible thermal insulation and decorative materials are prone to thermal melting and shedding when burning, which can easily ignite low-lying combustibles, causing "through-type, column-type" combustion. In addition, the external wind force will intensify the spread of the fire through openings such as windows and balconies to the interior of the building, breaking through the building's fire protection partitions from the outside, causing multiple floors and multiple households to catch fire quickly, forming three-dimensional combustion. When fighting fires on the facades of high-rise buildings, conventional water guns, water cannons, and vehicle-mounted cannons have limited ranges and are difficult to directly strike high-level fire points; various types of aerial vehicles cannot be used due to problems such as blocked fire passages, high-altitude firefighting site settings, and restrictions on on-site operating conditions. Rapidly deploy water. For this purpose, in the prior art, an automatic sprinkler system is generally installed on the exterior wall of a high-rise building. The automatic sprinkler system includes a sprinkler assembly and a drive assembly. Water is supplied to the sprinkler assembly through a water pump. When a fire occurs, the sprinkler assembly sprays water onto the exterior facade of the building, which can both reduce the temperature of the exterior facade and extinguish the open flame. The drive assembly is set to drive the sprinkler assembly to move on the exterior facade of the building, so that the sprinkler assembly can move to the location where the fire occurs to extinguish the fire. When a fire occurs on the exterior facade of the building, the automatic sprinkler system can extinguish the fire on the exterior wall of the building.

[0003] However, when the driving assembly drives the water spray assembly to move, the water pipe connected to the water pump also has to move accordingly. The water pipe filled with water has a certain weight, and one end of the water pipe is connected to the water spray assembly. The movement of the water pipe needs to be pulled by the water spray assembly. When the water spray assembly pulls the water pipe filled with water, the connection between the two will be subject to a large tensile force. Over time, the connection that is subjected to this tensile force will be damaged, and either water leakage will occur at this position, or the water pipe will fall off the water spray assembly, resulting in the water supply of the water spray assembly being affected, and ultimately affecting the fire extinguishing. In order to solve the above problems, an emergency fire extinguishing system for the exterior wall of a high-rise building is proposed. Utility Model Content

[0050] Furthermore, a controller 20 is provided on the cover 2 , and the motor 1 4 , the motor 2 10 , the motor 3 14 and the air pump 15 are all control-connected to the controller 20 .

[0051] The specific operation method of the utility model is as follows: when a fire occurs, the water pump is started through the controller 20, and water is supplied to the sprinkler head 32 through the water pipe 7, so that the sprinkler head 32 sprays water outward, and then the air pump 15 is started to inflate the air bag ring 1 113 and the air bag ring 2 162, so that the inner ring surfaces of the two are tightly fitted to the outer surface of the water pipe 7. At this time, the motor 1 4, the motor 2 10 and the motor 3 14 are started at the same time through the controller 20, so that the spray assembly 3 and the drive pipe assembly move at the same time, and the movement speeds of the two are controlled to be the same. In this process, the water pipe 7 filled with water is divided into three sections, and the first section is located at the connection between the water pipe 7 and the sprinkler assembly 3 and the air bag ring 2. The second section is located between the airbag ring 2 162, the second section is located between the airbag ring 2 162 and the airbag ring 1 13, and the third section is located between the airbag ring 1 113 and the water pump. At this time, the tube clamping assembly 11 clamps the water pipe 7 and drives the water pipe 7 between the airbag ring 1 113 and the water pump to move through the motor 2 10 and the motor 3 14. The water pipe 7 between the spray assembly 3 and the airbag ring 1 113 is pulled by the moving spray assembly 3, and the part that needs to be pulled by the spray assembly 3 is only the connection between the water pipe 7 and the spray assembly 3 and the airbag ring 1 113, thereby reducing the tension at the connection between the spray assembly 3 and the water pipe 7, and reducing the possibility of damage to the connection between the two due to tension.
