Pressure-adaptive water turbine paddle for hydroelectric generation

Abstract

The invention relates to a pressure-adaptive water turbine paddle for hydroelectric generation. The pressure-adaptive water turbine paddle for the hydroelectric generation comprises a locating shaft, a locating sleeve, a hydraulic cylinder, a transmission mechanism, a drive shaft, a paddle and a control system, wherein the locating shaft is hollow, the front end thereof is connected with a generator while the end is connected with the locating sleeve, the paddle is located outside the locating sleeve, the end thereof is connected with the locating sleeve through a rotating shaft, the hydraulic cylinder is located in the locating shaft, the transmission mechanism is located in the locating sleeve, the hydraulic cylinder is connected with the locating shaft in a sliding mode through a locating device, the transmission mechanism is connected with the inner wall of the locating sleeve in a sliding mode through the locating device, the drive shaft is located in the locating sleeve, one end thereof is connected with the drive mechanism while the other end is connected with the end of the paddle, and the hydraulic cylinder is connected with the transmission mechanism. The pressure-adaptive water turbine paddle for the hydroelectric generation is simple in structure, stable and reliable in running, low in use and maintenance cost, capable of precisely detecting the water flow pressure on the paddle of a hydroelectric generation turbine and capable of flexibly regulating the angle between the paddle and water flow so as to provide the stable power input for the generator and widen the effective use range of a hydroelectric generator.

Description

technical field [0001] The invention relates to a blade of a water turbine for pressure self-adaptive hydropower generation, belonging to the technical field of water turbine equipment. Background technique [0002] At present, in hydropower generation, the water turbine is the main equipment for converting the energy contained in the water flow into electric energy. Most of the impeller structures of the currently used water turbines are fixed, and the angle cannot be adjusted. Therefore, in order to ensure the pressure of the water flow on the surface of the impeller Stability. The current common method is to build equipment such as regulating valves outside the turbine to adjust the water flow. This type of equipment is often structurally responsible, with high operation and use costs, and the regulation accuracy of the water flow acting on the surface of the impeller is not high. Therefore, when the water turbine is in use, it is prone to unstable operation and limited...
