Backwater once-through water turbine

Abstract

A backwater direct-flow water turbine, characterized in that the bottom plate is fixed on the bottom ring, the upper part of the main shaft of the water turbine is connected to the generator, the lower outer ring of the main shaft of the water turbine is fixedly connected to the center sleeve of the water turbine with a connecting key, and the top plate of the water turbine and the bottom plate of the water turbine There are 6 water-guiding square pipes between the 6 vertical walls of the outer ring of the water turbine, and there are no less than 30 turbine blades evenly distributed on the outer ring of the center sleeve of the water turbine, and the turbine blades are evenly distributed on the bottom plate of the water turbine. There are 6 large tail water outlets and 6 small tail water outlets, and there are 6 air release pipes between the top plate of the turbine and the bottom plate of the turbine, which provide a way to automatically recover the tail water during operation. There is always a tail water circulation in the turbine body, and the water head is not directly The erosion hits the turbine blades, which can save more than 50% of water.

Description

Technical field [0001] The invention relates to a water conservancy power generation device. Specifically: the turbine blades are impacted horizontally and vertically to make the turbine shaft rotate. Background technique [0002] In the prior art, in the axial flow and mixed flow turbines, water impacts the turbine blades downward, and the water drains from the middle of the blades, which wastes water, has low power and low utilization rate. Due to underwater rushing, all the weight of the reservoir is pressed on the pressure bearing of the turbine, which is easy to damage and affects production. Summary of the invention [0003] The problem to be solved by the present invention is: according to the shortcomings of the prior art, to provide a tail water that can automatically recover tail water while running, there is always tail water circulation in the body, and the water head does not directly erode and hit the turbine blades, which is wear-resistant and resistant Erosion, c...
