The invention discloses an intelligent energy-saving water storage mechanism with a rotating and lifting mechanism. The intelligent energy-saving water storage mechanism comprises a bottom frame, anda rotation oil cylinder is fixed to the bottom face of the middle portion of a top plate of the bottom frame. A push rod of the rotation oil cylinder penetrates the top plate of the bottom frame and is fixedly provided with a main rotation plate. Vertical supporting plates are fixed to the two sides of the top face of the main rotation plate. Transverse plates are fixed to the tops of the verticalsupporting plates. The bottom ends of vertical screws are hinged to the main rotation plate. The top ends of the vertical screws are hinged to the transverse plates. An elevating frame is located between the two vertical screws. A water storage tank is placed in the elevating frame. Movable blocks are arranged on the two sides of the elevating frame and are in screw joint into the vertical screws. Rotation bevel gears are fixed to the lower portions of the vertical screws. Adjusting motors are fixed to the outer side walls of the vertical supporting plates. Height adjustment and position rotation of the water storage tank can be achieved, different using requirements are met, position adjustment can be conducted according to the length of a water pipe needing to be connected, and the intelligent energy-saving water storage mechanism is very convenient to use.
