Since both springs have the same spring characteristic and are in the same pre-stressed state and are also arranged at the same distance from the vertical axis of symmetry 19 of the container 3, the two torques generated by them are of the same size, but opposed to each other and therefore rise with respect to the Container 3 to zero.

  • the vibration exciter 8 When taking up operation, the vibration exciter 8 is placed in the guide 14 so that the cam 9 acting as the excitation element is in engagement with the pressure band 16 and thus with the container 3 (see FIG. 1).

  • Water 2 thus runs from the higher to the lower side of the container 3. If this process is initially considered statically, the water level 2 '(see dashed line in FIG. 1) would remain horizontal even in a tilted oblique position of the container 3. However, since the process is actually not static but dynamic, there is no exactly horizontal water level 2 'during operation - depending on the excitation frequency; nevertheless, even during (dynamic) operation, there is always a movement of the water 2 in the container 3 from the higher to the lower level or from the raised section of the container 3 to its lowered section.
  • Pivot axis 4 has been excited, and then - as described - has been disengaged, and it is assumed that the container 3 is in the tilt position shown in FIG. 2, in which the right spring 17 is further compressed, while it has relaxed the left spring 17, a pivoting process according to the arrow 20 ′, ie the container 3 moves, begins immediately thereafter from the dead position shown by way of example in FIG again with its right end upwards and with its left end downwards, passing the rest position, in which it is coaxially symmetrical to the horizontal axis of symmetry 25, and moves from the position shown in FIG.
  • crankshaft 24 is driven and can serve as a drive shaft for a machine unit or an electrical generator.
  • the vibration exciter 8 can be engaged again (briefly) in order to in turn move the container 3 into the intended maximum deflection position according to Bring angle ⁇ .

Abstract

Un dispositif de production d'énergie à partir d'un liquide en mouvement, notamment de l'eau, comprend un récipient (3) partiellement rempli d'un liquide et monté pivotant autour d'un axe de pivotement (4). Un générateur d'oscillations (8) fait quitter le récipient quitter une position neutre de repos et le fait basculer de manière qu'il oscille autour de son axe de pivotement. Un agencement de ressorts (17) espacé (a) par rapport à l'axe de pivotement est ou vient en contact avec le récipient déplacé de sa position de repos. Un convertisseur (21) convertit le basculement oscillant du récipient autour de l'axe de pivotement en un mouvement de rotation.
