Water diversion system with automatic sweeping function of water turbine

Abstract

The invention relates to a water diversion system with an automatic sweeping function of a water turbine. The water diversion system comprises a supporting mechanism, a sweeping mechanism, a lifting mechanism, a pool, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is arranged at one side of the pool; the water outlet pipe is arranged at the other side of the pool; a first flowmeter is arranged inside the water inlet pipe; a second flowmeter is arranged inside the water outlet pipe; a horizontally-arranged filter screen is arranged in the pool; and a water outlet valve is arranged at one side, close to the water outlet pipe, inside the pool. According to the water diversion system with the automatic sweeping function of the water turbine, a lifting drive motor in the lifting mechanism is controlled by a central processing unit to drive driving wheels to rotate; the filter screen is pulled to ascend by matching fixed pulleys with movable pulleys; meanwhile, a sweeping drive motor in the sweeping mechanism drives a screw to rotate, so that a cleaning block moves on the filter screen back and forth and pushes sediment onto sediment setting boards, further the automatic sweeping function of the filter screen is realized, and eventually the smoothness of water current in a water diversion chamber of the water turbine is guaranteed.

Description

technical field [0001] The invention relates to a hydraulic turbine water diversion system with automatic cleaning function. Background technique [0002] In the hydropower generation system, the water diversion chamber of the turbine is the first part where the water flow enters the turbine. It is mainly responsible for introducing the upstream water flow into the downstream impact turbine to generate electricity. Common water turbine water diversion chambers mainly include open type, tubular type and volute type. Different forms of water diversion introduce water flow to do work on the turbine. [0003] In the existing water diversion chamber, there is usually a lack of corresponding filtering measures, resulting in the mixing of sediment and other impurities in the upstream water flow. As these sediment impurities enter the key parts of the turbine and form accumulations, it is easy to cause the turbine speed to drop and the power generation efficiency to be low. It even...
