Abstract

The invention discloses a water turbine, which comprises a volute and a draft tube, the draft tube is installed on the side of the volute, the draft tube communicates with the inside of the volute and forms a water flow channel, and the water flow channel is provided with a runner, several pieces of guide The leaves, filter cartridge and shaft, the runner, guide vane and filter cartridge are all connected to the volute in rotation, the runner and guide vane are located in the filter cartridge, and several guide vanes are evenly distributed on the circumference of the runner. On the side, the shaft is located outside the filter cartridge. The shaft is equipped with a brush plate and a drive assembly that matches the filter cartridge. The brush plate is located at one end of the shaft and is fixedly connected with the shaft. The brush is in contact with the surface, and the driving assembly is located at the other end of the shaft and is rotatably connected with the shaft. The beneficial effect of the invention is: prolonging the service life.

Description

technical field [0001] The invention relates to the technical field related to 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] However, in the prior art, the guide vanes and impellers of the water turbine are often damaged by the impact of impurities such as sediment and stones in the water, which greatly reduces the servic...
