Two-way shaft tubular water turbine with automatic conversion

Abstract

Automatically converted two-way shaft tubular turbine, one end of the runner main shaft penetrates into the shaft, the other end of the main shaft is connected to the bearing seat, the outside of the bearing seat is connected to the support, the outside of the fixed wheel is connected to the support, and the support is connected to the shaft; There is a pair of right clutches on the right side of the two runners, and a pair of left clutches on the left side. The outer half of the clutches on both sides can rotate around the main shaft; there is a fixed wheel in the middle, and half of the clutches that cannot rotate on each side of the fixed wheel; there are two runners , there are half clutches on both ends of the runner, and the outer circle of the runner is evenly distributed with helical blades around the axis, one runner is a right helical blade, and the other is a left helical blade; the middle of the runner is matched with the main shaft. With a round hole, the runner can rotate around the main shaft and slide along the axis of the main shaft; the end faces of the right bearing seat and the left bearing seat have transmission mechanisms, clutches and planetary gear trains.

Description

technical field [0001] The invention relates to a tubular water turbine, in particular to an "automatically converted two-way shaft tubular water turbine", which belongs to fluid machinery and is a two-way tubular water turbine mainly used for tidal power generation. Background technique [0002] Chinese patent application number: 201310738718.6, "A two-way tubular water turbine using tidal power generation", including a forward water inlet channel, a shaft, a support frame, a two-way power generation runner, a reverse water inlet channel, a generator and a speed increaser , which is characterized in that it also includes a front equal-width movable guide vane and a rear equal-width movable guide vane; the front equal-width movable guide vane is arranged between the forward water inlet channel and the two-way power generation runner; The blades are set between the two-way power generation runner and the reverse water inlet flow channel. This patent application uses front and...
