Definitions

  • the present invention falls within the field of the use of discontinuous wave energy, in a coastal area or in front of a factory dike, for its transformation into continuous and manageable energy, whose main uses are the use of that energy in a coastal zone or the reduction of efforts on the levees.
  • the ES339502 background discloses a system that is fundamentally based on the creation of an air current, which even with waves of small magnitude, reach extremely high velocity values and therefore suitable for the operation of a turbine that by means of timely transmission mechanical, transmits a power provided to the system application installation.
  • This invention uses air as a fluid that drives a propeller and not water by driving a turbine like the present invention.
  • the background JP6101 ⁇ 468 discloses a power generation system from waves on the coast and ports that generates electricity through a plant which allows a wave near the shore to enter narrow ports arranged between the slope of a concrete floor and the concrete walls of the device, with rotating thrusters within said ports.
  • the performance is low and the energy difficult to harness.
  • EP0892889 refers to a submerged hydropneumatic wave energy converter that takes advantage of the difference in hydrostatic pressure of the crests and valleys of the waves by means of fixed units on the seabed comprising a piston coupled to a second piston with a smaller diameter movable in a hydraulic cylinder. The maintenance of the complex system is of great difficulty.
  • the invention comprises a hydropneumatic device that laminates the tips of incident energy (by reflection or breakage) and which allows the temporary tips to be absorbed in a pressurized air reservoir connected to the hydraulic circuit.
  • the pressurized air tank returns continuously, although variable in its intensity with the height and frequency of the absorbed wave energy tips, the average energy captured in these waves, when transmitting its pressure to the water contained in the hydropneumatic circuit .
  • This laminated energy can be used to generate electricity by means of a turbine and a turbined water delivery device at a depth level not affected by the movement of surface waves (in case of energy use), or returned to the sea at sufficient depth so as not to create navigation problems, (case of docks).
  • the invention allows:
  • the mass of water collected is channeled from the mouth through a collection and orientation duct of the decreasing section flow, with sectional variations along its path that guarantee low load losses in the duct.
  • each collection conduit the section of said conduit allows the installation of a unidirectional opening valve or clapper, preceded by a deaeration valve.
  • the seafront of the dike has a set of openings that constitute mouths of cells of decreasing section, thus forming a set of Capture elements and flow orientation.
  • the sectional variations along the cell path are designed to guarantee low losses of load in the duct, which translates into a high energy efficiency for the use of energy, and a low effort on the structure in the use of the invention 'for dissipating dikes.
  • each collection duct its section is suitable for the installation of a unidirectional valve or clapper, which prevents the return to the sea side of the water received by the cell: the kinetic energy of the water body opens the valve against the pressure energy of the water contained in the hydropneumatic cargo tank into which it flows. Once the kinetic energy of the incoming wave is consumed, the valve is closed against the internal hydropneumatic pressure energy, whereby much of the energy of the captured wave is incorporated into the hydropneumatic circuit.
  • the discontinuous energy transforming hydropneumatic system of waves in continuous energy comprises:
  • the openings can have various geometric shapes and variable dimensions, conditioned downstream of the hydraulic circuit by the dimensions of the flow control elements (valves, pipes and gates) and the permissible speed in them.
  • the total surface of the set of openings covers the total of the expected wave attack front.
  • the partitions that limit the openings chosen have in the attack front of the wave the structurally necessary width to resist the efforts that the maximum expected wave generates.
  • the dimensions of the mouth of the cells may not be uniform if the specific conditions of the project advise it, depending on the tidal race and the expected energy density linked to the height of the wave at different levels of the. catchment front.
  • An adjustable deaeration valve connected to the end of each convergent duct followed by a unidirectional opening valve. Due to maintenance needs or eventual replacement, the valves or clappers must be protected by upstream and downstream gates, and conservation access such as a galena must be provided.
  • the deaeration valve is both sensitive and quick to open or close depending on the magnitude of the forces that both sides request it alternately, and resistant and durable against repeated long-term efforts with the period of the train of waves they capture, and the opening of the unidirectional valve is conditioned by the maintenance of the desired pressure in the hydropneumatic circuit.
  • a pressure integrating balance tank composed of a closed hydropneumatic system, or alternatively an equilibrium chimney, which receives water from the collector or collectors.
  • the hydropneumatic system can be constituted by a large diameter load pipe that runs along the dike to its extremity in the sea, to a suitable depth so as not to disturb the navigation (case of the port dike), or so that at the elevation
  • variations in hydrostatic pressure may be considered void, linked to a pressurized air reservoir disposed on it, or split the large diameter pipe section between water and air, both under pressure.
  • the cargo pipe is wrapped in structural concrete and its axis is arranged at a lower level than the minimum expected tide level.
  • the air fraction of the hydropneumatic reservoir can be arranged in a variable way, depending on the conditions of the location of the specific use. Depending on the case, it may consist of the upper part of the horizontal pipe, another upper horizontal pipe linked to it, or a vertical tank that starts from the first.
  • a Francis or Bulb turbine located at the end of the load pipe is added to the system.
  • the turbine zone is equipped with guard gates, access well, and other devices necessary for maintenance.
  • the front of reception (facing the sea) of the system is prolonged depending on the physical conditions of the stretch of coast in which it is implanted and the expected wave energy until the desired final power in turbine is achieved.
  • the plant of the front of reception can be straight or gently curved to adjust to the coast: so much by the capture by openings as by the circuits of load of the cells, there is margin for curves of wide radius.
  • the operation of the system is as follows:
  • the water from the breaking wave which is mixed with air, penetrates through the mouth.
  • the incoming wave compresses that air that can be derived, through a deaeration valve, into the atmosphere.
  • the deaeration circuit is blocked if the hydropneumatic tank requires additional air (for example by dilution in the water of the air it contains).
  • the collection line empties the water that has not passed the intake valve into the sea.
  • the kinetic energy of the water body opens the unidirectional opening valve against the water pressure energy contained in the link pipe with the collector of the hydropneumatic circuit.
  • the hydropneumatic charging system collects the kinetic energy of all wave capture mouths as pressure energy. Once the kinetic energy of the incoming wave is captured, the unidirectional opening valve is closed. In this way, kinetic energy is transformed into pressure energy in the hydropneumatic reservoir.
  • Each mouthpiece can provide energy at different times and in different amounts to the tank: the hydropneumatic configuration of the tank allows the integration of partial energies to be integrated, and at the same time standardizes the total water pressure thanks to the air reservoir.
  • the water pressure energy can be transformed into mechanical energy in the turbine chamber, height variable load, which is located at one end of the cargo line of the hydropneumatic tank that runs parallel to the coast.
