a water turbine

Abstract

The invention discloses a water turbine and relates to the technical field of water turbines. The invention comprises a water turbine case, the top of the water turbine case is fixed with a water guide tube through a support rod, the bottom end of the water guide tube is fixed with a water outlet pipe which communicates with the inner cavity of the water guide tube and penetrates to the inside of the water turbine box, and the inside of the water guide tube is fixed with a spiral An aqueduct, a water injection pipe is fixed on the outer surface of the aqueduct; the outlet end of the water injection pipe runs through the outer wall of the aqueduct and extends to the inside of the aqueduct; The present invention uses the combined use of the water guiding cylinder, the spiral water guiding pipe, the water injection pipe, the rotating shaft, the fixed plate and the inclined water retaining blades to improve the impact force of the water flowing water on the inclined water retaining blades when the water flow is flowing. When impacting, first use the potential energy of the water flow itself to improve the comprehensive utilization rate of energy and reduce the waste of resources.

Description

Technical field [0001] The present invention belongs to the field of water turbines, and in particular to a turbine. Background technique [0002] The turbine is an important energy conversion device that converts the water flow into mechanical energy, which is also an important core unit for hydraulic power generation. The existing turbine mainly includes a volute, tail water tube, a wheel, and a generator. The flowing water flow flows from the inlet of the volute to form the high pressure water flow impact wheel, and the tail water pipe is discharged, and the transfer is driven during this process The wheel rotates and then drives the generator to rotate power by the drive shaft. [0003] Although the existing impact turbine can meet the power generation needs, when running, after the nozzle is sprayed to the blade, the air flow is rotated in the direction of the water flow, but the direction of the water discharge direction In contrast, the water flow in the reverse direction ...

Problems solved by technology

[0003] Although the existing impact turbines can meet the demand for power generation, when the nozzles spray water to the blades, the blades will drive the wheel to rotate, but the direction of the sprayed water will also follow the rotation direction of the wheel. On the contrary, the water flow in the opposite direction is easy to spray on the next blade, which will produce a certain resistance to the rotation of the wheel disc, resulting in a decrease in the speed of the wheel disc, so that the power generation of the generator per unit time is low; not only that, the existing water turbine is in use At this time, the initial impact energy generated by the water flow is only used to drive the rotation, and the potential energy utilization effect of the relatively gentle water flow is poor, especially the potential energy generated by the gentle water flow before entering the turbine. There is no further utilization method, and there is a certain degree of energy waste.
