Embodiment Construction

[0018] The present invention is a V-shaped safety connecting rod mechanism of the water guide mechanism of a tubular water turbine. The main components are assembling relation see figure 1 Shown: The eccentric pin 5 and the connecting rod pin 11 are respectively assembled with the ball bearing 4 using the retaining ring 12, and the two ball bearings 4 are respectively installed in the hole of the V-shaped safety connecting rod 1; the bearing plate 2 is fixed in the bolt 3 On the V-shaped safety connecting rod 1, it is used to compress the ball bearing 4; the detection plate 8 is fixed on the side of the V-shaped safety connecting rod 1 by bolts 6 and spring washers 7; the limit switch 9 is fixed on the V-shaped safety connecting rod by screws 10 1 on; the action contact of the limit switch 9 is in contact with the detection board 8.

[0019] The said V-shaped safety link mechanism transmits the operating force of the servomotor when it is working normally. When the guide vane is s...

Abstract

The invention provides a V-shaped safety connecting-rod mechanism for a water guiding mechanism of a through-flow turbine. The V-shaped safety connecting-rod mechanism for the water guiding mechanism of the through-flow turbine is composed of a V-shaped safety connecting rod, bearing pressing plates, bolts, ball bearings, eccentric pins, bolts, spring washers, a detection plate, a limit switch, screws, connecting pins and check rings. When a guide vane gets stuck due to foreign matter in the closing process, the V-shaped safety connecting rod can be bent and broken when servomotor operating force borne by the V-shaped safety connecting rod reaches a certain threshold value, other guide vanes continue to be closed normally under the effect of the servomotor operating force, and thus the effects of protecting the water guiding mechanism is achieved; and the V-shaped safety connecting-rod mechanism is simple and reliable in structure, convenient to maintain, low in manufacturing cost, and suitable for water guiding mechanisms of small-size and medium-size through-flow turbines.

Description

[0001] Technical field: [0002] The invention relates to a V-shaped safety connecting rod mechanism for a water guiding mechanism of a tubular water turbine. [0003] Background technique: [0004] At present, the water guiding mechanism of the tubular water turbine usually adopts a spring safety linkage mechanism, which is reliable in action, but has a complicated structure and a high cost, and is suitable for a large tubular water turbine. The V-shaped safety link mechanism is more suitable for small and medium-sized tubular turbines. When the guide vane is blocked by foreign objects during the closing process, the corresponding V-shaped safety link will break, which will not affect the normal closing of the remaining guide vanes. Replace the V-type The unit can operate normally after the safety linkage. The V-shaped safety link has a simple structure and is easy to maintain. Since it is a small probability event that the guide vane is stuck by a foreign body when it is closed, ...
