Description

Technical Field

[0001] This utility model relates to a multifunctional spray water gun assembly, belonging to the field of fire-fighting equipment technology. Background Technology

[0002] Water hoses are one of the core pieces of equipment for firefighters in fire suppression. However, the limitations of conventional water hoses are quite apparent when facing certain types of fires. For example, when extinguishing fires involving flammable materials such as wood, straw stacks, and cotton stacks, these materials are prone to smoldering, and surface spraying of water alone is insufficient to thoroughly penetrate the deeper layers of the burning material. Even if the external flames are quickly suppressed, the interior may continue to smolder, posing a risk of reignition. In such cases, firefighters often need to turn over the stacks layer by layer and then spray water point by point, which is not only physically demanding and time-consuming but also has limited overall fire extinguishing efficiency. In confined spaces where personnel cannot easily access the area, traditional water hoses are even less effective.

[0003] Similar problems have also occurred in fires involving new energy vehicles. The power batteries in new energy vehicles are typically installed at the bottom of the vehicle. Once a fire is triggered by an impact or short circuit, the battery pack often continues to burn, releasing a large amount of heat energy, and may explode due to thermal runaway during firefighting. Traditional water cannons, due to limitations in jet angle and penetration, have difficulty directly targeting the battery modules located at the bottom of the vehicle, resulting in ineffective firefighting and even exacerbating the fire by failing to cool the batteries in time. Utility Model Content

[0004] This utility model aims to address the aforementioned technical problems by providing a multifunctional spray water gun assembly. By integrating multiple working components into a housing, it enables the rapid assembly and functional switching of various fire-fighting equipment, thereby improving fire extinguishing efficiency.
