Water storage tank for fire fighting

A water storage tank for fire fighting belongs to the technical field of fire fighting equipment, and comprises a water storage tank, a pipeline and a control module, and the water storage tank comprises a pure water storage tank and an additive storage tank; the pure water storage tank is communicated with the additive storage tank through a connecting pipeline with a third electromagnetic valve; and the control module controls the opening and closing of the third electromagnetic valve to realize whether an additive in the additive storage tank is added into the pure water storage tank or not. Through data acquisition of a fire scene, a fire source causing a fire is preliminarily and rapidly analyzed, and whether a fire extinguishing additive is added into a water storage tank or not is determined. In order to solve the problem that an existing water storage tank is single in function, the utility model provides the multifunctional water storage tank capable of adding an additive for assisting fire extinguis
