Water turbine

Abstract

The invention discloses a water turbine, and relates to the technical field of water turbines. The water turbine comprises a water turbine box, wherein a water guide barrel is fixed to the top of thewater turbine box through a supporting rod; a water outlet pipe which communicates with an inner cavity of the water guide barrel and penetrates into the water turbine box is fixed to the bottom end of the water guide barrel; spiral water guide pipes are fixed in the water guide barrel at equal intervals in the axial direction; a water injection pipe is fixed to the outer circular surface of the water guide barrel; the water outlet end of the water injection pipe penetrates through the outer wall of the water guide barrel and extends into the water guide barrel; and the end, located in the water guide barrel, of the water injection pipe communicates with the water inlet ends of the spiral water guide pipes. According to the water turbine, the water guide barrel, the spiral water guide pipes, the water injection pipe, a rotating shaft, a fixing disc and inclined water blocking blades are combined for use, so that the impact force of water flow on the inclined water blocking blades can be improved when the water flow flows, when the water flow impacts a wheel disc, the potential energy of the water flow is utilized in advance, the comprehensive utilization rate of energy is improved,and the waste of resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of water turbines, in particular to a water turbine. Background technique [0002] The water turbine is an important energy conversion device that converts water flow energy into mechanical energy, and it is also an important core unit for hydropower generation in the utilization of new energy. The existing water turbine mainly includes a volute, a draft tube, a runner and a generator. The flowing water flows from the water inlet of the volute into the spiral and accelerates to form a high-pressure water flow that impacts the runner and is finally discharged through the draft tube. The wheel rotates, and then drives the generator to rotate and generate electricity through the transmission shaft. [0003] Although the existing impulse turbines can meet the demand for power generation, when the sprinkler sprays water to the blades, the blades will drive the wheel to rotate, but the direction of the sprayed wa...

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, s
