The above-mentioned patents are all about the study of urban building facade fires under the action of no wind and ambient wind, and none of them involve the effect of ambient wind on the fire spread and smoke diffusion of buildings.
[0005]
Through the search of relevant patents, there is no research on the fire of ancient buildings in villages under the action of environmental wind. Therefore, a related fire simulation experiment device can be established to study the fire overflow of ancient buildings in villages caused by the fire of the openings of ancient buildings under the action of environmental wind.

Embodiment Construction
[0036] The invention will be further described below in conjunction with the accompanying drawings.
[0037] figure 1 It is a schematic diagram of the overall structure of the present invention, a fire simulation experiment device for building groups induced by village ancient building fires under the action of environmental wind, mainly including an air supply system 1, a building group model 7, a quality monitoring system 14, a rotating chassis 10, and a three-dimensional movable Thermocouple array holder8. The wind supply system 1 is used to provide an external wind field required for simulating a village building group under the action of ambient wind. The air supply system 1 is composed of a fan 2, a rectifying pipe 3 and an air supply outlet 4, and the fan 2 is connected to the rectifying pipe 3 and the air supply outlet 4 in sequence. There are multiple rectifier tubes 3 arranged in rows and columns. The outside air is blown in by the fan 2, passes through the rectif...

The invention relates to a simulation experiment device for building group fire induced by village ancient building fire under action of environmental wind, which is mainly used for researching the evolution behavior that flame overflows from an opening and develops outwards after a village ancient building fire occurs, and building group fire occurrence-development-spreading evolution laws and behavior characteristics under the action of external environment wind. The device comprises an air supply system, a building group model, a fire source system, a quality monitoring system and a matched measurement monitoring system. The device can simulate the fire spreading evolution law of the village ancient building group under the action of different environmental wind, and research and characterize the change of related parameters of the evolution mechanism of the village ancient building group. According to the invention, the experimental device model for simulating the fire opening fire overflow behavior of the ancient village building group is established for the first time so that the fire spreading and smoke diffusion behavior of the building group induced by the fire opening fire overflow of the ancient village building group under the action of environmental wind can be simulated more truly; and the device has important reference significance and value for formulating an effective village ancient building fire prevention and control and smoke control and reduction method.
Description
technical field [0001] The invention relates to the technical field of fire safety, in particular to a fire simulation experiment device for building group fires induced by village ancient building fires under the action of environmental wind, which is used to study the fire spread and smoke of building groups induced by the fire overflow of village ancient building openings under the action of environmental wind transport behavior. Background technique [0002] Traditional villages integrate folk history and ancient architectural art, and are an important treasure house of Chinese history, culture and ancient architecture. Residential buildings in the village are adjacent to each other, and the distance between buildings is small. Once a fire breaks out in a certain room in the village, the flame will easily overflow from the window opening to form a building opening fire overflow, and the overflowing flame will easily ignite adjacent external buildings, especially When th...
