Definitions

  • the present invention relates to a pole-like arrangement according to the introductory portions of the independent claim.
  • WO9313355A1 discloses a lamp post with a small wind power plant.
  • the power from the wind power plant may be used to power the lamp, and in order to use the power as efficiently as possible a photo detector is arranged on the pole such that the lamp only is lit when necessary. Connectors may also be provided on the post such that the power may be used externally.
  • WO2006022590A1 discloses another pole with a wind power plant, solar cells and in addition a arrangement that utilizes the heating effect of the suns radiation.
  • the solar heat arrangement comprises a funnel shaped part that is heated by the sun and generates a flow of hot air that flows through the interior of the pole a powers a turbine with a generator.
  • a problem with power generated by solar heat, solar radiation and wind is that it may only be stored for a limited period of time in a battery. Solar heat and solar radiation further gives power only during the day and this means that when lamp posts consumes a maximum amount of power, the least amount of power is being generated.
  • An object of the invention is therefore to provide a pole-like arrangement is able to generate power during calm and in darkness.
  • the invention relates to a pole-like arrangement, typically a lamp post, comprising at least one air turbine 4, 4a, b with generator. At least one air conduit extends in the interior of the pole and the air turbine is arranged in the air flow from the at least one air conduit. A winding ground air path 2 is connected to the air conduit, which has the advantage that an air flow to the air turbine may be generated as long as there is a temperature difference between the ground and the air, thus also during night and calm.
  • the pole may further be provided with solar cells 5, 5a, b or a solar heat powered air flow generator 7, and the winding ground air path 2 supplements these by also generating power in darkness. This is advantageous particular for lamp posts as they consume power primarily when it is dark.
  • the invention further relates to such a pole with at least one conduit provided with inlets 3a-d on the sides of the pole that gathers more wind generated air flow which is directed towards a turbine.
  • Fig. 1 shows a first embodiment of the invention in partial cross section
  • Fig. 2 shows a second embodiment of the invention
  • Fig. 3 shows a third embodiment of the invention
  • Fig. 1 shows a first embodiment of the invention in partial cross section.
  • the figure shows a lamp post 1 with a street light 6 mounted at the upper end of the pole.
  • the pole has a vertical portion that near the upper end inclines and this inclined part is directed towards a turbine 4.
  • the turbine 4 is attached at the upper end of the pole and is arranged to rotate when it is affected by the wind, but also when it is affected by air flow emitted from the hollow pole.
  • the turbine is connected to a generator that generates current when the turbine rotates.
  • the current may be used in the pole for powering the lamp or be connected to the power grid and contribute to the general power production.
  • the hollow pole 1 has five internal conduits that exit at the upper end of the pole and the air flow that is emitted from the upper end powers the turbine.
  • Four of the conduits have inlets(3a-d) on the sides of the pole and as the wind blows, this gives rise to an air flow entering the inlets, flowing through the conduits and out through the mouths of the conduits at the top of the pole.
  • the inlets thus act as wind collectors and effectively gives the turbine a larger collecting area. This enables the turbine with the pole designed in this way to generate more current that what would otherwise have been possible.
  • a winding ground air path 2 is connected to the lower end of the pole, being situated underground.
  • the winding ground air path sucks air into an inlet and emits the air from an outlet that enters a fifth conduit through the interior of the pole.
  • the ground heat heats the air in the winding ground air path and the hotter air then tends to flow upwards, further contributing to the power of the turbine.
  • the winding ground air path is schematically illustrated as a block shaped unit through which a pipe is winding, but in a realistic case the pipe would extend along a longer distance through the ground.
  • the winding ground air path may comprise pipe parts that runs close to the surface of the ground in order to make use of solar heated dirt, but may also comprise pipe parts that runs deeper down in order to make use of ground heat that is not an immediate result of heating by solar radiation.
  • solar cells 5 are arranged that may further contribute to generation of power.
  • the advantage of the invention is thus to utilize pre-existing poles, such as for example lamp posts, for power generation.
  • pre-existing poles such as for example lamp posts
  • generators may conveniently be arranged by pre-existing poles and the generated power may further be used locally with small transmission losses.
  • Fig. 2 shows a second embodiment of the invention.
  • the figure more clearly illustrated how the inlets (3a-d) at the sides of the pole are provided with funnel-like devices for more efficiently gathering air flow.
  • This embodiment too has a turbine, a lamp and a winding ground air path.
  • the conduit in the poje are however not visible as the figure does not illustrate a cross section.
  • An electronics unit 8 is arranged on the pole that comprises battery, control electronics controlling charging and discharging of the battery, generation of desired voltages for supplying to the power grid, local use in the lamp or being accessible at a connector 9 on the pole.
  • the electronics unit may further be controlled by a photo detector that affects when and how the lamp is being switched on or off.
  • the connector 9 is intended for powering or charging electrical devices such as for example electrical golf carts or electrical lawn mowers.
  • Fig. 3 shows a third embodiment of the invention, where the lamp post has a bifurcated upper portion.
  • a lamp 6a, b with a generator and a solar cell panel 5a, b are arranged.
  • the pole has, as in the previous embodiments, internally extending conduits through which air flows from the inlets 3a-d on the sides of the pole and from the winding ground air path.
  • the conduits may be divided at the bifurcated upper portions in different ways. All the conduits may for example bifurcate such that both turbines are arranged at moths where air exiting flows.

Abstract

La présente invention concerne un aménagement du type poteau doté d'une turbine à air (4, 4a, b) avec générateur. Une conduite d'air s'étend dans l'intérieur du poteau et la turbine à air est disposée dans le flux d'air provenant de la conduite d'air. Un trajet sol/air à enroulement (2) est relié à la conduite d'air et apporte un flux d'air à la turbine à air, ledit flux pouvant être généré tant qu'il existe une différence de température entre le sol et l'air, ainsi également pendant la nuit et les périodes de calme. Le poteau peut en outre être doté de piles solaires (5, 5a, b) ou d'un générateur de flux d'air alimenté par la chaleur solaire (7), et ledit trajet (2) complète ces derniers en générant également de l'énergie dans l'obscurité. L'invention concerne en outre un tel poteau comportant au moins une conduite dotée d'admissions (3a à d) sur les côtés du poteau rassemblant plus de flux d'air généré par le vent qui est dirigé vers une turbine.
