[0021] When the booster water supply device for building fire protection facility engineering of the utility model is used, in order to ensure that the impurity content of the water source entering the booster pump 2 is reduced, the water source is introduced into the water inlet filter box 4 through the water inlet 8 and filtered through the combined filter element 9 composed of at least four groups of filter plates 901, and then the filtered water enters the booster pump 2 through the input pipe 6 connected to the water outlet 7, and then is pumped into the pressure regulating tank 3 by the booster pump 2 to wait for use. When the filter plate 901 needs to be disassembled and cleaned, first slide and open the cover plate 12, control the movable plate 10 to rise through the lifting mechanism 11 to drive the combined filter element 9 connected to the movable plate 10 to rise, and then remove the filter plate 901 for cleaning and then install it for continued use. At the same time, the number of filter plates 901 entering the water inlet filter box 4 can be controlled by the lifting mechanism 11 to ensure that at least one group of filter plates 901 is located inside the water inlet filter box 4 below the water outlet 7. The fewer the number of filter plates 901 located inside the water inlet filter box 4, the smaller the pressure resistance will be, which is suitable for pressurizing water sources with less impurities.
