Low-head and high flow water turbine machine
First Claim
1. A low-head and high flow water turbine machine, comprising:
- a water-guiding base, configured to have a hollow cylindrical-shaped accommodating space formed therein, wherein the hollow cylindrical-shaped accommodating space has an upstream segment with an inlet at a upstream side and a downstream segment with an outlet at a downstream side, the water-guiding base further comprising a bottom plate, a first and a second lateral plates respectively coupled to two opposite sides of the bottom plate, and a top plate arranged on the first and second lateral plates, the first and the second lateral plates respectively having a first and a second water-guiding walls, each of which has a tapered tower shape, respectively protruded from the first and the second lateral plates to a circumference of the hollow cylindrical-shaped accommodating space, wherein a first and a second guiding slots are respectively arranged at an end of the first and the second water-guiding walls, and the first and the second water-guiding walls are respectively misaligned and arranged anti-symmetrically to a central axis of the hollow cylindrical-shaped accommodating space such that the upstream segment is formed as a smoothly converged flow channel while the downstream segment is formed as a smoothly diverged flow channel;
a water turbine, arranged in the hollow cylindrical-shaped accommodating space of the water-guiding base, the water turbine further comprising a rotating shaft and a plurality of blades, wherein two ends of the rotating shaft respectively pass through an axle hole formed on the bottom plate and top plate and are respectively connected to the bottom plate and the top plate corresponding to the hollow cylindrical-shaped accommodating space through a bearing; and
a cylindrical-shaped gate shell, configured to pass through the top plate and slidably coupled to a circumference of the water turbine around the upstream side, wherein the two lateral sides of the cylindrical-shaped gate shell respectively slidably coupled to the first and the second guiding slots whereby an opening degree of the cylindrical-shaped gate shell can be adjusted through sliding the cylindrical-shaped gate shell for adjusting a cross-sectional area of a stream flow so as to control a stream discharge of the water turbine, switching off operation of the water turbine, and adjusting a water level at the upstream side to be at a high water level state.

Abstract
A low-head and high flow water turbine machine comprises a water-guiding base having a top plate, a bottom plate, an accommodating space defined therein, an inlet and an outlet respectively arranged at upstream side and downstream side, and a first and a second lateral plates respectively having a first and a second water-guiding walls that are respectively extending inward toward circumference of the accommodating space, a water turbine arranged in the accommodating space and having multiple blades, and a cylindrical-shaped gate shell passing through the top plate and slidably coupled to circumference of water turbine around upstream side wherein an opening degree is adjusted through sliding the gate shell for adjusting cross-sectional area of stream thereby controlling stream discharge entering to the water turbine, switching off rotation of the water turbine, and adjusting water level at high water level state at upstream side according to the stream discharge requirement.
