Water turbine capable of automatically descaling back surface of wheel fan

Abstract

The invention discloses a water turbine capable of automatically descaling the back surface of a wheel fan. The water turbine comprises a box body, wherein a flushing pipe is arranged on the left sideof the box body in a penetrating manner; a water outlet pipe is fixedly connected to the bottom of the box body; a wheel body is rotatably connected inside the box body; a bearing ring is rotatably connected inside the wheel body; the wheel fan is arranged on the surface of the wheel body in a penetrating manner; a water spraying pipe is slidably connected to one side, close to a wheel center, ofa water pushing rod; a water inlet pipe is fixedly connected to the side surface of the water spraying pipe; a hollow pipe is engaged with the side surface of a transmission gear rod; a speed changegear is engaged with the side, away from the wheel center, of a transfer rod; a transmission gear is engaged with the side surface of the speed change gear; and a scraping wheel is arranged at the side surface of the transmission gear in a penetrating mode. According to the water turbine capable of automatically descaling the back surface of the wheel fan, a bearing gear is matched with the scraping wheel to use, so that the effect of automatically descaling the back surface of the wheel fan when the water turbine runs is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a water turbine capable of automatically cleaning the scale on the back water side of the fan. 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. As early as around 100 BC, the prototype of the water turbine appeared in China - the water wheel, which was used to lift irrigation and drive grain processing equipment. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. [0003] After the existing water turbine has been running for a long time, it needs to be shut down to clean the scale inside the water turbine, especially on the back side of the water retaining fan, it is difficult to get the water to wash away, so it is easy to cause the accumulation of scale, and the accumu...
