EP3458708A1 – Oscillating Device For Converting Fluid Kinetic Energy Into Electrical Energy – Google Patents

Abstract violet particle wave background According to the energy conservation laws, the extraction of the electrical energy from the coil reduces the amplitude and lowers the lOfrequency of the oscillations below a threshold at which the collected energy is drastically reduced or zero. 30rotation axis. The two extremities of the coil are electrically connected to the two extremities of the wind-wheel’s conductive shaft collecting the coil induced current. In the embodiment of fig 3 and 4 the electrical energy transfer through the pipe’s (or duct’s) wall is based on the induced current being alternate: it can be transferred by a capacitive coupling. For all the above described embodiments it is 5possible to extract the collected electrical energy, both to measure the flow rate and to collect electrical energy just extracting the induced current in a wire passing through a hole in the pipe.

Fig 3 and 4 show a detail of a capacitive system to transfer the electrical signal across the pipe wall, respectively, with a section view, along a diametrical plane, an axial plane and a detail of a transversal section of the pipe. In this way the flow is concentrated in the part of the pipe corresponding to one of the two half- sections resulting from a cut of the circular section along a diameter. Fig 9A and 9B show an embodiment with a conveyor as the one depicted in Fig 5 in combination with an interacting element with blades with coils like in the example of Fig 7, the magnetic field and the lOmagnets In this description and in the claims, the definition “element mechanically interacting with the fluid flow” can have any embodiment. Fig 7 and 8 show two variations of the placement 5of the coil or coils generating the induction signal.

This invention describes a specific arrangement 25to improve and adapt the established technique of transforming rotating movement into electrical energy by means of coils inside a magnetic field, specifically addressing the issue of optimizing the efficiency of energy harvesting for a fluid moving in 30a pipeline or any kind of closed conduct. Fig.6 shows the specific embodiment of a -blades wind-wheel. The resulting configurations ensure that 15there is no steady position for the wind-wheel preventing the incoming flow to knock one blade at least and trigger the rotation. According to an improvement, the coil is electrically connected with the ends of the oscillating axle, departing from diametrically opposed sides of the interaction element, the endsbeing of electrically conductive material and connecting the mentioned coil on one side with the unit collecting the electrical signal generated by induction. Como aliviar el dolor de una hernia discal lumbar . The energy harvesting of the fluid movement requires a rotating coil embedded in a magnetic field.

Because of the symmetry, a further improvement allowing to further optimize harvesting consists of a magnetic field constant in time but variable in the space, such that it inverses its polarity when 5crossing the plane representing the pipeline’ s cross- section and containing the wind-wheel rotating axis. 15 the rotation axis is preferably a central axis in the projection of the shape of the interaction element on the cross-section plane of the fluid flow and it corresponds to the central diametrical axis on the transversal section of the fluid. It is named equivalently “wing”, “fluttering surface”, “leaf”, “foil” when it is a flat element 15with any aerial projection shape, showing similar behaviour in a fluid.
