The invention discloses a fluid combined sliding and rotating energy collecting device. According to the device, a frame is used as a main body, a circular track rotating structure is adopted, one-way deflection hinge baffle flow blade units are combined into a rotating blade frame, and a spring is used for controlling the wind quantity of the blade units to be combined with a base of the rotating blade frame and a circular drive gear ring into a whole. The device is rotated stably on a circular track through a pulley or magnetic suspension, and then rotating energy is transmitted by the circular drive gear ring to a generator set. The fluid combined sliding and rotating energy collecting device is a set of rotating device integrated by combination components, the dependence of the existing large energy collecting device, such as a wind turbine, on large equipment for manufacturing, transportation, installation, maintenance and the like is avoided, the cost of each link is greatly reduced, and a new chance is created to utilize kinetic energy of airflow, ocean current and rivers, so that a larger fluid generator set can be manufactured possibly. The generator set of the device can be refitted into a motor, and blades are shaped properly, so that the device can be used as a city entertainment landscape device.
