PURPOSE: A frame supporting device in a tidal power generator is provided to prevent the failure of a generator and to make possible the construction of tidal power generation facilities. CONSTITUTION: A frame supporting device composed of many float balls(2), a fixing anchor(5), a sensing sensor(4) and an air pump(3) is operated to feed a signal to the air pump according to the sensing of the level of the water by the sensing sensor if the level of a frame(10) and the water are lowered due to the rise of the water level. The air pump fed with the signal of the sensing sensor is immediately driven and injecting air into the float balls. Accordingly, the float balls are expanded and lifted up at a moderate level from the surface of the water according to more strong buoyancy. Then a drum winding of the wire in the fixing anchor for fixing the frame rotates and unwinds the wire of the anchor. And the sensing sensor senses the separation of the frame from the surface of the water and stops the driving of the air pump and thereby the floated state is maintained. |
