Definitions

  • the present invention relates to an electric power generator driven by the air stream produced by the passage of vehicles in general.
  • the aim of the invention is to eliminate the drawbacks noted above by providing an electric power generator driven by the air stream produced by the passage of vehicles in general which is first of all arranged so as to not be exposed, so that it causes no environmental impact, and furthermore does not constitute a hazard, since the rotating parts are adequately protected.
  • an object of the invention is to provide an electric power generator that is capable of optimizing the utilization of the air stream, thus allowing to provide an energy recovery that is assuredly desirable from a practical and commercial standpoint.
  • Another object of the present invention is to provide an electric power generator that thanks to its particular constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
  • Another object of the present invention is to provide an electric power generator that can be obtained easily starting from commonly commercially available elements and materials and is also competitive from a merely economical standpoint.
  • an electric power generator driven by the air stream produced by the passage of vehicles in general which comprises, at at least one side of a path affected by the passage of vehicles in general, a vane-type turbine connected to a generator, characterized in that it comprises an air conveyance element that accommodates said vane-type turbine.
  • the electric power generator driven by the air stream produced by the passage of vehicles in general is preferably installed at a roadside and, in the case of a dual-carriageway highway, it is installed at the center between the protective barriers, so that it is affected by an air stream in two opposite directions determined by the passage of vehicles on both carriageways.
  • a highway path is shown in the specific example, but the path may obviously be of any kind, such as a railroad track, an airport runway and so forth; in any case, all those situations in which there are vehicles generating an air stream that can be utilized.
  • a concrete median barrier is considered which is of the type known as "New Jersey"; a turbine 2 is arranged between the protective barriers, designated by the reference numeral 1, and generally drives an electric generator 3.
  • a particular feature of the invention consists in that the turbine 2 is accommodated inside an air conveyance element, which is constituted by a housing 10 that surrounds the turbine 2 and is provided with diametrical openings 11 located at slots 12, which are formed directly within the concrete barrier 1 and preferably have a cross-section that tapers up to the opening 11, which is arranged at the end, as shown in Figure 6, of a duct 13 for conveyance inside the housing 10, which has a narrower cross-section, so that the impact of the air on the turbine 2 occurs at a higher speed.
  • an air conveyance element which is constituted by a housing 10 that surrounds the turbine 2 and is provided with diametrical openings 11 located at slots 12, which are formed directly within the concrete barrier 1 and preferably have a cross-section that tapers up to the opening 11, which is arranged at the end, as shown in Figure 6, of a duct 13 for conveyance inside the housing 10, which has a narrower cross-section, so that the impact of the air on the turbine 2 occurs at a higher speed.
  • the vane-type turbine can assume various shapes; thus, for example, as shown in Figures 7 and 8, it is possible to provide a turbine 20 that is mounted on a hollow shaft 21 and has, between the various vanes 22, gaps 23 that facilitate the inflow of the air, which can be disposed of easily, for example by means of openings 25 that can be provided on the cover 26 arranged so as to close the housing 10.
  • Figure 9 shows a turbine 30 with helical vanes, which allows to optimize the angle of incidence of the air on the vanes in order to optimize the thrust and efficiency of the rotating body.
  • Figure 10 illustrates a turbine 31 with helical vanes having a variable cross-section, i.e., a cross-section that decreases axially so as to better allow to utilize the angle of incidence of the air both for abundant streams and especially for modest and inconstant streams of air.
  • Figure 11 illustrates a turbine 32 provided with flat vanes that are inclined with respect to the axis, so as to facilitate both collection and discharge of the air.
  • the intake slot of the road barrier for air inflow is arranged in axial alignment with respect to the central cross-section, the inclination facilitates the outflow of the air; if instead the opening of the barrier for air inflow is lower or higher than the central cross-section of the turbine, it is possible to achieve an improvement of the outflow in relation to the different angle of incidence of the air.
  • Figure 12 illustrates a spherical turbine 33, which ensures good uniformity of the motion for generating the centrifugal force that concentrates most of the weight toward the middle circumference.
  • the spherical shape of the turbine allows to collect in an optimum manner the air if the inlet of the road barrier is in axial alignment with the central cross-section of the turbine.
  • Figure 13 shows a turbine 34 with flat vanes arranged axially, which ensure outflow of the air, during progressive rotation, tangentially to the angle of incidence of its collection.
  • Figure 14 illustrates the turbine 35, which has a hemispherical shape, so as to collect most of the air in the region of maximum radial expansion of the vanes and allow outflow in the region of minimum expansion of the vane.
  • Figure 15 shows a cylindrical turbine 36, which allows to optimize air collection in the case of a large inlet of the road barrier with constant volumes.
  • Another particularity of the invention is further constituted by the fact that a spacer 40 is arranged in axial alignment with the turbine, as shown in Figure 2, and can act as a flywheel so as to even out the rotation of the turbine.
  • step-up unit 41 which is adapted to increase the turns transmitted to the electric power generator, accordingly increasing its yield.
  • FIGS 17 and 18 illustrate a barrier of the guardrail type, designated by the reference numeral 50: in this case, on the guardrail there are holes 51, whose flaps 52 provide in practice an engagement element for the housing, again designated by the reference numeral 10, to the side of which deflectors 53 are arranged which are adapted to constitute an air stream conveyance element.
  • the deflectors 43 provide in practice a housing for collecting the air that arrives from the openings provided in the undulation of the guardrail and from the openings provided at the base of the road barrier and between the various undulated elements that constitute the guardrail.
  • the housing is adapted to strengthen the guardrail proximate to the openings provided for collecting air and to prevent insertion of people and objects.
  • Figures 19 to 21 show another embodiment that is particularly suitable for separation barriers constituted by guardrails.
  • a supporting body 61 which is for example U-shaped and on which there are coverings 62 that generate, as shown in Figure 21, an air passage chamber, inside which the horizontal-axis turbine is arranged.
  • the turbine is connected to a generator 63, with the optional interposition of a step-up unit.
  • One aspect that must not be neglected, moreover, is constituted by the fact that the generated electric power is a clean energy from a renewable source, which is remunerated at a higher price by the market.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
