Definitions
- the invention that is the subject of the present description is a device designed to be backed up against vertical sea or port protection dikes, allowing the production of energy, and more precisely in the field of the production of electrical energy from the energy of the swell.
- the field of the invention is the exploitation of wave energy or wave energy, contained in the movement of the swell, that is to say from successive waves born from the effect of the wind at the surface of the sea and sometimes spread over very long distances.
- wave energy or wave energy contained in the movement of the swell, that is to say from successive waves born from the effect of the wind at the surface of the sea and sometimes spread over very long distances.
- wave energy or wave energy contained in the movement of the swell, that is to say from successive waves born from the effect of the wind at the surface of the sea and sometimes spread over very long distances.
- wave energy or wave energy contained in the movement of the swell
- the objectives of the present invention are:
- the device which is the subject of the invention has the particularity of capturing directly, through a free float, the variation of the vertical sea level due to the swell, that is to say, it directly exploits the translational movements.
- vertical sea or port protection dikes By equipping vertical sea or port protection dikes with this device, we benefit from the advantages of on-shore (accessibility, connection, shelters, low investment and maintenance cost) while being offshore (non-damped swell - full energy around vertical protective dikes).
- the device By controlling the interactions with the fixing elements, thanks to a system of triple rails installed on the wall of the dike, the device makes it possible to widen the field of exploitation of the energy of swell by going towards amplitudes of swell more important.
- the device is equipped with an amplification system making it possible to channel incident swells and amplify the energy incident to the device, which will optimize its efficiency and extend the operating periods.
- the device is equipped with a self-balancing system based on float density distribution to limit parasitic movements, as well as a ballasting system for total immersion in the event of a strong storm.
- Figure 1 shows a top view of the device installed on a vertical protective dike with amplification.
- Figure 2 shows a side sea view of the device installed on a vertical protective dike with amplification.
- the device is composed of a free float (1) making it possible to directly exploit the variation of the sea capturing the energy of the swell in the form of potential energy.
- the float has a minimum average density of 0.8 with a post ballasting density of up to 1.05. This float includes:
- the float (1) is guided by a lateral movement pipe system (2), with 3 rails taking advantage of the support and verticality of the box walls, to ensure the horizontality and the follow-up of the upward / downward movement.
- the stroke of the motion channeling system is designed to sweep all cases of exploitable swell energy.
- the use of the walls makes it possible to extend the operating interval of the device to the large amplitudes of the swell. No contact between the wall of the vertical dikes and the float (1) is allowed thanks to the movement pipe system (2).
- Cylinders (5) which transform mechanical energy into hydraulic energy, by exploiting the two directions of movement, upward and downward.
- Controlled flow pressure accumulators (7) which receive variable hydraulic energy and transmit at output a continuous and uniform flow with a capacity which reaches 20 cycles of upward downward movement (10 min maximum).
- a hydroelectric turbine (9) making it possible to transform the flow of hydraulic energy into electrical energy.
- Sensitive components are housed in conditions of optimal durability.
- This invention can be used in:
- the shape of the vertical wall can be flat or the like.
- the objective is to revolutionize the role of port or maritime protection facilities, by moving from swell hunting to its use to produce green energy.
