The invention discloses a concealed self-starting fire-fighting equipment for fire-fighting in buildings, which belongs to the field of intelligent equipment. Concealed self-starting fire-fighting equipment for fire-fighting in buildings, including fire-extinguishing unit, water delivery unit, sensing unit and return unit. The sensing unit is located in the lower floor. When a fire occurs, the magnetic connection is maintained, and the fire extinguishing unit can only reciprocate in the vertical direction. It can realize that when there is no fire, the equipment is hidden in the floor, which improves the aesthetics, expands the available space for object handling, and effectively avoids equipment being hit. In the event of a fire, the equipment can automatically extend out of the floor, and spray water only after the equipment extends out of the floor, effectively preventing fire water from flowing into the floor and causing electrical damage.
