Water turbine with regulating and filtering functions for power generation

Abstract

The invention relates to a water turbine with regulating and filtering functions for power generation. The water turbine with the regulating and filtering functions for the power generation comprisesa water guiding tank, a machine frame, a conduit, a volute, a driving mechanism, a draft tube and a generator; a regulating mechanism and a filtering mechanism are arranged on the upper part of the water guiding tank, and the regulating mechanism includes a detection assembly, a water tank, a flow guiding tube, a water draining tube and a water supply tube; and the filtering mechanism comprises two filtering assemblies, and the filtering assemblies include filtering screens, sealing rings, garbage bins, turnover units and translation units. According to the water turbine with the regulating and filtering functions for the power generation, the flow velocity of the water is controlled by the regulating mechanism, the water turbine can output power steadily, the practicability is improved, moreover, the fixity such as sediment and gravel in the water is cleaned through the filtering mechanism, the wear and tear of guide vanes is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a water turbine for power generation with regulating and filtering functions. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tail water pipe. The higher the water head and the greater the flow, the greater the output power of the turbine. [0003] Due to the change of water flow velocity, the output power of existing water turbines is not stable, which reduce...

AI Technical Summary

Problems solved by technology

[0003] Due to the change of water flow velocity, the output power of existing water turbines is not stable, which reduces the practicality. Not only that, but the water introduced by existing water turbines often contains some silt or gravel, which is easy to wear the guide vanes of water turbines, and also May clog pipes, which is cumbersome to clean and increases maintenance costs
