Horizontal water turbine

Technical Field

The utility model relates to the technical field of water turbine power generation, in particular to a horizontal water turbine.

Background

The small-sized vertical water turbine comprises a speed regulator, a generator, a water turbine, a long speed regulating shaft, a push-pull rod and a control ring, wherein the speed regulator is a built-in speed regulator of the servomotor and is arranged on a generator layer, and the servomotor of the speed regulator is connected with the long speed regulating shaft of the water turbine through a rocker arm. The speed regulator of the vertical water turbine adopting the long speed regulating shaft structure transmits torque through the long speed regulating shaft of the water turbine, and the long speed regulating shaft drives the push-pull rod and the control ring of the water turbine to move, so that the flow of the water turbine is regulated, and the regulation of the start-up, shutdown and load of the unit is realized. The long speed regulating shaft is adopted, and the speed regulator is connected with the push-pull rod and the control ring of the water turbine into a whole through the long speed regulating shaft; the long speed regulating shaft consists of an upper end shaft, a connecting pipe with a flange and a lower end shaft, and the length of the long speed regulating shaft reaches about seven meters, so that the long speed regulating shaft is inconvenient to install and is not attractive in arrangement.

In the prior art, the erosion of the power station, especially the water turbine runner, top cover and bottom ring guard plates, upper and lower leakage stop rings, guide vanes and other overcurrent components of the multi-sediment power station is serious, vortex is formed in the runner, the uniform flow of water flow is affected, the hydraulic efficiency is reduced, the vibration and noise of the water flow are increased, and the service cycle of the overcurrent components is shortened. Meanwhile, the formation of vortex can accelerate the damage of a runner, so that vicious circle is formed, the safe and stable operation of a unit is seriously influenced, the water pressure of the tubular turbine is generally unstable, and the efficiency of power generation is influenced when the water pressure of the tubular turbine is large and small.
