[0045] The invention provides a master control switch for a hydraulic turbine governor, comprising a photoelectric switch and a contact plate 1 connected to a control switch 2, the control switch 2 is moved by the action of a hydraulic cylinder 3, and the hydraulic cylinder 3 The push rod 4 is connected to the control switch 2.

[0046] The outer cover of the photoelectric switch is provided with a sealed protective shell 5, and also includes a trigger mechanism for triggering the photoelectric switch;

[0047] The trigger mechanism includes a reflector, a rotating shaft and a contact rod; wherein,

[0048] The rotating shaft is rotatably connected to the protective housing 5, one end of the rotating shaft is connected to the reflector, the other end of the rotating shaft is connected to the contact rod, and the reflector is located inside the protective housing 5, and the contact rod Located on the outside of the protective shell 5; the reflector corresponds to the position of...

Embodiment 2

[0075] A water turbine governor provided by the present invention includes the master control switch for the water turbine governor in Embodiment 1 above.

[0076] The turbine governor provided by the present invention, when in use, when the contact plate 1 moves with the control switch 2, the contact plate 1 can be in contact with the contact end of the contact rod to push the contact rod to rotate, and the contact rod drives the rotating shaft to rotate , the rotating shaft further drives the reflector to rotate, and the reflector can rotate with the rotation of the contact rod to the position where the photoelectric switch can be triggered. When the photoelectric switch is triggered, the inclination angle of the blade can be obtained according to the position of the triggered photoelectric switch; during use , because the outer cover of the photoelectric switch is provided with a sealed protective shell 5, through the protective shell 5, impurities such as oil and dust can b...

Embodiment 3

[0079] A water turbine provided by the present invention includes the master control switch for the water turbine governor in the first embodiment above.

[0080] The water turbine provided by the present invention, when in use, when the contact plate 1 moves with the control switch 2, the contact plate 1 can be in contact with the contact end of the contact rod to push the contact rod to rotate, and the contact rod drives the rotating shaft to rotate, and the rotating shaft then Drive the reflector to rotate, and the reflector can rotate with the rotation of the contact rod to the position where the photoelectric switch can be triggered. When the photoelectric switch is triggered, the inclination angle of the blade can be obtained according to the position of the triggered photoelectric switch; during use, due to the photoelectric The outer cover of the switch is provided with a sealed protective shell 5, through which impurities such as oil and dust can be isolated on the out...

Abstract

The invention provides a master control switch for a hydraulic turbine governor, a hydraulic turbine governor and a hydraulic turbine, wherein the master control switch for the hydraulic turbine governor comprises a photoelectric switch and a contact plate connected to the control switch, and the photoelectric switch has a The outer cover is provided with a sealed protective casing, and also includes a trigger mechanism for triggering the photoelectric switch; the trigger mechanism includes a reflector, a rotating shaft and a contact rod; wherein the rotating shaft is rotatably connected to the protective casing, and one end of the rotating shaft Connect the reflector, the other end of the rotating shaft is connected to the contact rod, and the reflector is located inside the protective shell, and the contact rod is located outside the protective shell; the position of the reflector and the photoelectric switch Correspondingly; the position of the contact rod corresponds to the position of the contact plate; and a reset mechanism for the reset of the contact rod is also included. The invention solves the technical problems that the operating environment of the water turbine in the prior art has a lot of oil pollution and dust, the impurities easily touch the photoelectric switch by mistake, and the real-time position of the blade cannot be accurately obtained.

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...
