Claim 1:
2. The tidal current energy generating device of claim 1, wherein the concavo-convex portion comprises a first concavo-convex portion and a second concavo-convex portion opposite to each other; the tidal current is configured to flow along the first direction or the second direction; the adjustment wheel is configured to abut on the first concavo-convex portion; the adjustment plate is configured to be driven under the action of the tidal current flowing along the first direction to move along the first direction relative to the adjustment wheel, so that a position where the first concavo-convex portion is in contact with the adjustment wheel is changed to allow the adjustment wheel to swing to drive the impeller blade to rotate around the axis of the impeller blade relative to the impeller hub, adjusting the angle of the impeller blade; the adjustment wheel is configured to abut on the second concavo-convex portion; the adjustment plate is configured to be driven under the action of the tidal current flowing along the second direction to move along the second direction relative to the adjustment wheel, so that a position where the second concavo-convex portion is in contact with the adjustment wheel is changed to allow the adjustment wheel to swing to drive the impeller blade to rotate around the axis of the impeller blade relative to the impeller hub, adjusting the angle of the impeller blade.
