Embodiment Construction

[0010] The present invention is described below in conjunction with accompanying drawing.

[0011] Such as figure 1 The water diversion device of the water turbine shown includes a volute 1 with a discharge port 2 at the bottom of the volute 1, a filter screen at the water inlet of the volute 1, and an air vent 3 at the top of the volute 1, and the volute 1 is welded by steel plates. In the working state, the volute makes the water flow generate a certain amount of circulation, and the water is introduced into the water guide mechanism with the minimum loss. The bottom of the volute is equipped with a drain to remove the dirt, sediment and water in the volute. There is an air release hole on the top of the volute to discharge the air in the volute when the volute is filled with water.

[0012] The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention. Substantial equivalent changes or modifications shall fall...

Abstract

The invention discloses a water diversion device for a water turbine, comprising a volute, wherein a drain hole is arranged at the bottom of the volute. The water diversion device is simple in structure and convenient in use, has high water diversion efficiency and can prevent impurities such as silts from being deposited.

Description

technical field [0001] The invention relates to a water turbine, in particular to a water diversion device for a water turbine, belonging to the technical field of water conservancy equipment. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tail water pipe. The higher the water head and the greater the flow, the greater the output power of the turbine. Impact turbine is a kind of water turbine, which has been widely used all over the world due to its high energy conversion efficiency. Various types of impact tu...
