Zusammenfassung: | The utility model relates to a tubular turbine control ring auxiliary supporting device which comprises a water inlet pipeline, a positioning ring, a control ring and a servomotor, the side of the control ring is connected with an inner gear ring, an outer gear ring is rotatably installed on the outer side of the water inlet pipeline and located at the position of the inner gear ring, and an auxiliary assembly is arranged between the outer gear ring and the inner gear ring. The utility model relates to the technical field of water turbine control ring assistance. The utility model has the beneficial effects that the inner gear ring is limited through the arranged auxiliary assembly, so that the auxiliary assembly supports the control ring through the inner gear ring, and the guide vane is prevented from rotating towards a closed state due to the fact that the guide vane is impacted by overlarge water flow impact; therefore, the fixed control ring is deformed due to the acting force, and the overall stability |
