Abstract

The invention provides a master control switch for a water turbine speed regulator, the water turbine speed regulator and a water turbine. The master control switch for the water turbine speed regulator comprises a photoelectric switch and a contact plate connected to the control switch, the outer side of the photoelectric switch is covered with a sealed protective shell, and the master control switch further comprises a trigger mechanism used for triggering the photoelectric switch. The trigger mechanism comprises a reflector, a rotating shaft and a contact rod; the rotating shaft is rotatably connected to the protective shell, the reflector and the contact rod are connected to the two ends of the rotating shaft respectively, and the reflector and the contact rod are located on the innerside and the outer side of the protective shell respectively; the position of the reflector corresponds to that of the photoelectric switch; the contact rod corresponds to the contact plate in position; and a reset mechanism used for resetting the contact rod is also arranged. The technical problems that in the prior art, a large amount of greasy dirt, dust and impurities exist in the operation environment of a water turbine, a photoelectric switch is easily touched by mistake, and the real-time position of a blade cannot be accurately obtained are solved.

Description

technical field [0001] The invention relates to a water turbine, in particular to a master control switch for a water turbine governor, a water turbine governor and a water turbine. 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. In the process of use, the inclination angle of the turbine blades is controlled by the turbine governor, and then the effect of speed regulation is achieved. The forward and backward movement of the hydraulic cylinder push rod can control the inclination angle of the blades; the position of the inclination angle of the blades is determined by three contact switches. Acquisition, the front contact switch indicates that the blades are fully open, the middle position contact switch indicates that the blades are half open, and the rear contact switch indicates that the blades are fully closed; the contact s...
