Rotary-shaft water-feeding type water turbine

Abstract

The invention relates to a hydraulic turbine with water supply by revolving spindle, comprising shell, upper cover, rotary spindle and power output gear on the rotary spindle. A closed water cavity is formed between shell and upper cover. It is characterized in that upper flow and lower passages arranged in certain angle are set in the rotary spindle, the diameter of lower flow passage is less than one of upper flow passage; the end of rotary spindle is supported by bearing of rotor load-bearing platform, injecting mechanism is fixed on the rotary spindle and inlet pipe less than flow passage and connected with it is set in the shell; drainage device is set on the bottom of shell; injecting mechanism is rotor water storage room formed by upper and lower plates of rotor wheel and injecting port is set on the lower plate of rotor wheel. It is provided with energy saving and low cost, conquers a mass of water flows out of the vane circumference and among vane, avoids water-hinder phenomenon and makes full use of water resource. It is no-pollution drainage and has an influence for human protection absolutely.

Description

technical field [0001] The invention relates to a device for generating energy by using water energy as an energy source, in particular to a water turbine used in power stations, ships and submarines to generate electric energy and drive the ships and submarines to run. Background technique [0002] There are many types of existing turbines, all of which are driven by water or water vapor to drive blades or turbines to drive rotors and shafts to rotate, and one end of the shaft outputs energy to drive generator rotors or propellers to generate electricity or drive ships to run. Large-scale hydropower stations are built with high dams and store water deeply. The potential energy of the water is obtained by the high dam, and then the vortex is introduced into the water turbine at the bottom of the dam, and the huge rotor is driven by the high water head to generate a large amount of energy. The rotor drives the generator , to generate electrical energy. The steam turbine of t...

Problems solved by technology

[0003] Water falls from a high place to do work on the blades of the turbine. This method usually uses a large amount of water to impact the smaller blades. A large amount of water flows outside the circumference of the blades or between the blades, but a large amount of hydraulic power is not obtained. Fully utilized, there will be a retardation effect between water molecules, which will affect the speed of the rotor and cause a lot of waste of water resources

In order to obtain a certain rated output power, only the height of the dam body is provided, which greatly increases the investment cost
