Water turbine transmission mechanism with controllable output

Abstract

The invention discloses a water turbine transmission mechanism with controllable output. An annular inner shell is fixedly connected to a mandrel through a connecting ring, meanwhile, the inner shellis sleeved with an outer shell, an annular inner cavity is defined by the outer shell and the inner shell, outer ring axial sliding rods are evenly distributed on the inner wall of the outer shell, inner ring axial sliding rods are evenly distributed on the outer wall of the inner shell, the outer ring axial sliding rods are sleeved with multiple outer ring friction pieces, the inner ring axial sliding rods are sleeved with multiple inner ring friction pieces, and multiple pushing and driving mechanisms parallel to the axial direction are evenly distributed on the inner wall of the outer shell. The rotating speed of a runner can be changed and the runner can stop rotating by controlling the pushing and driving mechanisms, the interference degree of runner blades on an inner bin of a waterturbine is controlled, and therefore a safety passageway can be provided for upstream and downstream fishes. By means of the water turbine transmission mechanism, an upstream fish gate can be controlled to be opened and reduced or the water turbine can stop working in the fish flow period, and a condition is provided for timing automatic control.

Description

technical field [0001] The invention belongs to the hydraulic turbine transmission technology in the field of hydraulic ecological engineering, and in particular relates to a hydraulic turbine transmission mechanism with controllable output. Background technique [0002] Hydropower generation uses the water potential to drive the rotor blades of the water turbine to rotate, which in turn drives the generator to rotate to generate electricity. During the working process of the water turbine, the rotating blades will cause harm to the fish. During the long-term work, the fish will continue to be harmed. The existing hydroelectric power generation device usually cuts off the upstream and downstream channels of the fish, and relies on upward migration to complete the process. Migratory fish have a strong impact on the life cycle, and there are also impacts on non-migratory fish. Fish will suffer serious injuries as they descend through ordinary water turbines. Studies by some ...
