ES2613040T3 – Direct-drive Rotational Wave Energy Conversion – Google Patents

Beneficios de la Fisioterapia personal a domicilio para.. This condition causes the vertical oscillation movement of the stringer 13 to move opposite (180 degrees out of phase) to the vertical oscillation movement of the floats 11 and 12. This stringer design that lowers and rises is achieved using a camera compressible ballast in the lower section of the crossbar (not shown). The CoE is further reduced by reducing the capital expenditure of the generator by optimizing the electromagnetic design using a large diameter generator when a low speed rotary motion and high torque are employed. Operating and maintenance costs are reduced through the system’s operational design; there are parts that move minimally, and the parts that move do so fluidly, with incoming waves, to reduce the effect of rapid loading often experienced by deployed marine bodies. It is well known in the generator design technique that the increased speed, in general, allows a reduced cost. The combined effect of the design results in a fluid movement of the wave converter in the ocean, which reduces the structural load, reduces the mooring load, and adjusts to the tidal variation.

\ A power take-off (PTO) can be mounted on stringer 13 or floats 11 and 12, and can be mounted in any location as appropriate for specific design considerations. The vertical oscillation movement of this system creates a relative rotation movement between the floats 11 and 12. By connecting the PTO only between the floats, the only energy captured is the relative motion energy between the floats. Dolor de espalda al lado izquierdo . Additionally, it has been shown that the correct location of the ballast on the crossbar can increase the captured power and can also be used to optimize the relative speed between the crossbar and floats. A shorter stringer 13 also reduces the overall system cost, power absorption optimization, and PTO speed optimization, lowers the position of the damping plate and increases the vertical oscillation response.

In another embodiment, a single PTO can be connected to drive shafts 18 and 19, so that a rotor (not shown) joins the bow float 11 and the stator is attached to the stern float 12 (or vice versa). An example of a wave energy converter is provided in WO 2008/063086, which discloses a relatively fixed reactive body attached to a single float, in which the majority of the surface of the wave energy converter It is below the surface of the water. In another embodiment, two PTOs can be mounted inside the housing 30, or mounted on the surface outside the beam, enclosed in a water-tight box on the port and starboard sides of the system as shown in Figure 9. In this Second arrangement, PTO 37 has a rotor (not shown) attached to a float 11 and a stator (not shown) attached to the other float 12. The opposite is true of PTO 38, which has a rotor (not shown) attached to the float 12 and a stator (not shown) attached to float 11. Both PTOs are driven by relative movement between floats 11 and 12. The same advantage of the increased generator speed is realized between the stator and the rotor, because each It rotates in opposite directions.

Ortopedia - Zapato postoperatorio The yaw rotation of the floats allows the floats to rotate to be perpendicular to the axis of rotation of the PTO in the housing 30. The floats can also rotate in the arms 47 and 48 to be parallel with the axis of rotation of that PTO, or somewhere between parallel and perpendicular positions.

A wave energy converter is also described which provides an approximation of wave energy as a rotary that will operate with a DDR generator or any other power take-off (PTO) driven by a mechanical rotary drive shaft. Complementing wave energy with solar energy provides a more continuous power supply of each WEC especially when wave energy is low during the summer months. The power extraction efficiency is increased by the correct orientation of the floats 11 and 12 and the axes of rotation with respect to the front of the incoming wave.
