Description
Technical Field
The utility model belongs to the technical field of the fire control is put out a fire, especially relates to a high pressure water jet extinguishing device.
Background
With the rapid development of economy and society, the frequency of building fires is higher, and the fires in the places with dense people occupy a considerable proportion. Since the loss of fire in a person-intensive place is too great, the prevention and control of the fire in the person-intensive place has been an important task for fire fighting. The intensive places are mainly places where people work, live, study, entertainment and the like are highly concentrated, and meanwhile, the intensive places are also the concentrated places of inflammable and explosive articles, the building structure is relatively complex, and the specific gravity of underground buildings, overground buildings and high-rise buildings is large. When a fire disaster happens in a dense place, the fire disaster is diffused quickly, a great amount of dense smoke and toxic gas generated by combustion easily obscure the sight of trapped people, and the generated high-temperature and hot air flow make people unbearable, so that the phenomena of panic and incapability of taking care of people and mutual crowding easily occur, which inevitably leads to too slow evacuation, and increases the possibility of poisoning and suffocation casualties. And meanwhile, the fire fighting and rescue work of the fire fighters is seriously influenced. In case of fire in the building or other closed space, the traditional fire extinguishing method is that the fire fighter must break open the door and window and put into the fire to extinguish the fire. In the face of dangerous situations such as explosion, collapse and falling objects which can happen at any time, the personal safety of firefighters cannot be guaranteed. According to statistics of relevant departments in the United states, the method comprises the following steps: firefighters who are sympathetic in fire rescue in the united states die 37% of them from foreign object strikes and 15% of them from building collapses. Among them, 18.5% of firefighters are casualties caused by collapse of buildings or falling of building components when entering people are evacuated or no people need to be rescued to extinguish fire. When high-pressure water is sprayed, the volume of water at the outlet of the water gun does not expand, so that the water is not accelerated due to the volume expansion. In order to improve the spraying speed and distance of water mist and reduce the particle size of water drops to enable the water drops to cover an ignition area in a wider range, compressible high-pressure gas and high-pressure water are sprayed simultaneously to form water jet, the compressed gas is decompressed and expanded to carry water flow and improve the water flow speed to enable the water flow to be sprayed farther, and the gas disperses the water flow into fine water mist with smaller particle size to enhance the fire extinguishing performance of the water mist.
The short-distance fire disaster and the long-distance high-altitude fire disaster exist in the actual fire disaster, the existing fire extinguishing device cannot effectively adjust the range and switch the gas-liquid mixing mode, and therefore the fire extinguishing device is low in applicability. In order to achieve a stronger fire extinguishing effect, the fire extinguishing apparatus requires a larger water flow rate and a more dispersed water mist. In part of high-pressure jet extinguishing devices, the overvoltage protection of a high-pressure air path and a high-pressure water path is not arranged, so that potential safety hazards are brought.
