Definitions

  • the present invention relates to an energy conversion system addressed to the production of electricity from the energy released from people and/or vehicles motion, to an horizontal surface that is part of the pavement where they are moving, which is slightly displaced while they are passing, and consequently actuates a mechanical system, that converts the vertical linear movement into a rotational one, which drives an electric generator.
  • This modular system allows the integration of multiple units in order to increase the generation capacity.
  • One of the aims of the present disclosure is to create an energy conversion system to be applied in the pavement, intended to harvest the energy wasted from people and/or vehicles, during its motion on the movable surface, in order to generate electricity.
  • the movement of people and/or vehicles over the surface which is part of the system, drives an electromechanical system that converts the harvested kinetic and potential energy in electrical energy. Besides the capability to generate electricity, the system also can store it for latter consumption.
  • the present disclosure is useful to allow the electric energy generation through renewable and alternative means, without any fossil fuel as energy resource, having as its main advantage the zero green house gases emissions (essentially C0 2 ) l during the process of electric energy production, that decreases the negative environment impact, which is common to electricity generation technologies.
  • Another advantage related to this technology consists on its diversity of applications, which one can be actuated by people and/or vehicles, allowing its implementation on several places: on the pavement of inner spaces as shopping malls, gyms, sports facilities, night clubs, among other places with great people affluence; in pavement of outside spaces as sidewalks, crosswalks, pedestrian bridges and recreation areas; in roads: on slowdown zones like pedestrian crosswalks, speed humps or speed bumps areas, toll zones, highway exits among other places high vehicle affluence where a speed reduction is required.
  • the electric energy generation is still highly dependent on thermal power plants supplied by fossil fuels (coal, natural gas or oil derivatives) and nuclear energy, having been verified in the past decades an increase on the implementation of electric energy generation systems based on renewable sources, namely hydroelectric power plants and wind farms, Onshore and Offshore. Solar energy have been gathered in photovoltaic and thermoelectric power plants, whose feasibility is doubtful due to their high costs of installation and low conversion efficiency.
  • the present invention detaches form the latter described by introducing an alternative system, whose generation density is much higher than the systems referred above, which turns the electric energy production from the pavement much more sustainable.
  • Other systems designated for the same purpose make use of hydraulic or pneumatic mechanisms operating as intermediaries in the energy conversion process. Most part of these, convert the mechanical energy into potential pressure energy, which is stored in a pressure accumulator for later use to drive an hydraulic actuator or turbine coupled to an electric generator, in order to produce electric energy.
  • the present invention is different from the previously referred by overcoming these limitations, since it presents a simple and compact electromechanical system which allows the generation of equivalent, or higher, energy quantities, relatively to the formerly mentioned technologies, by coupling several modular units with different configurations in order to maximize the system overall generated energy.
  • This method does not allow the use of the full load, since a part of it is distributed by the support where the extremity rotates reducing, consequently, the amount of captured energy.
  • the present invention overcomes this issues once its surface is held flat, to do not disturb the people or vehicles traffic and for achieve a better use of the forces exerted on it, since the latter are equally distributed and transferred from the surface to remain mechanical system, maximizing the harvested energy conversion.
  • the present invention partly follows the system related in the patent PT105126 (WO2011145057), where the main differences are found in the force transmission system from the surface to the generator, where the linear bearing components have been suppressed, as well as the method and elements of force transmission from the surface to the arm.

  • the generator shaft can be driven in just one angular direction (preferred configuration) or in both (using the energy transferred to the surface during its downward movement, as well as the energy stored in the spring, during the surface ascension).
  • the present disclosure relates to an electromechanical system suitable to generate electric energy from mechanical energy released by people and vehicles to the pavement.
  • the system consists on a block constituted by a fixed and a movable part.
  • the fixed part comprises the lower base, that is settled on the pavement and supports all the remaining mechanical elements of the conversion system.

  • a load is applied on the surface, by the passage of a person or a vehicle, the latter is displaced from its initial position, describing an essentially vertical movement, with a very small horizontal movement.
  • the load is uniformly distributed by the four columns, that are fixed to the lower base of the movable superior surface where, each one, is pivotally connected to an arm, which is rigidly coupled to a shaft, very much like a crank or crankshaft (the arm is the crank; the shaft is the shaft of the crankshaft, the columns is the crankshaft connecting rod which moves in reciprocating linear motion).
  • the vertical linear movement of the surface will induce a rotational motion in the shafts, which rotates relatively to the base, where each shaft is actuated by a pair of columns/arms.
