Havturbine til produktion af energi via bølgerSea turbine for energy production via waves

AnvendelsesområdeField of application

Frembringelsen er en bølgegenerator, der består af en flyder, der følger bølgernes bevægelser op og ned. I flyderen er monteret diverse dynamoer m.m. beregnet til at lave strøm.The generation is a wave generator consisting of a float that follows the up and down waves of the waves. Various dynamos etc. are mounted in the float. intended to power.

Dynamoerne i flyderen drives via en aksel, der går vertikalt i dybden, så dybt, at den relative forskel mellem havoverfladens, og dermed flyderens, bølgebevægelse, og dennes aftagen i dybden udnyttes til at drive akslen rundt med samme omdrejningsretning, hvad enten flyderen går op på en bølgetop, eller ned i en bølgedal.The dynamos in the float are driven via a shaft that goes vertically in depth, so deep that the relative difference between the sea surface, and thus the float, wave movement, and its decrease in depth is utilized to drive the shaft with the same direction of rotation, whether the float goes up on a wave peak, or down in a wave valley.

Akslens omdrejning igangsættes via en påmonteret skrue, udformet med fastmonterede kileformede blade.The rotation of the shaft is initiated via a screw mounted on a wedge-shaped blade.

Kendt teknik.Prior art.

Der er lavet mange forsøg på at udnytte havets indhold af energi. Enten via udnyttelse af bølgerne eller ved at udnytte forskellen mellem ebbe og flod.Many attempts have been made to exploit the ocean's energy content. Either by exploiting the waves or by exploiting the difference between ebb and flow.

De bølgemaskiner jeg er bekendt med, er for komplicerede i deres konstruktion, hvilket gør dem sårbare for de enorme og uberegnelige kræfter de udsættes for. En del forsøger sig med afledet energi via tanke med luft, hvor trykforskel og luftgennemstrømning skal igangsætte turbiner. 2 store forsøg er lavet ved Hanstholm, hvor bølgebevægelsen trækker et stempel op og ned.Begge er havarerede på grund af naturens kræfter, men ville under alle omstændigheder være blevet ødelagt af tilsanding, idet man benytter en bundkonstruktion, der ikke alene er fortøjning som i foreliggende tilfælde, men har teknisk betydning for konstruktionens virkemåde.The wave machines I am familiar with are too complicated in their construction, making them vulnerable to the enormous and unpredictable forces they are exposed to. Some try with derived energy via tanks with air, where pressure difference and air flow must start turbines. Two major attempts have been made at Hanstholm, where the wave movement pulls a stamp up and down. Both have failed due to the forces of nature, but would in any case have been destroyed by sanding, using a bottom structure that is not only mooring as in The present case, however, has technical significance for the operation of the construction.

Ved metoder med afledet energi, er der naturligvis et unødvendigt energitab.Of course, with methods of derivative energy, there is an unnecessary loss of energy.

Problemer at løse Væsentlige problemer der skal tages højde for, når man forsøger at udnytte bølgeenergi er fortøjningen, tilsanding ved bundkonstruktioner, de enorme uberegnelige kræfter havet frembringer i form af "forkerte bølger", strøm, pludselige vindstød- og skift med meget mere.Solving Problems Major issues to consider when trying to harness wave energy are the mooring, sanding at bottom structures, the immense unpredictable forces the ocean produces in the form of "wrong waves", power, sudden gusts and shifts and much more.

HAVTURBINENHAVTURBINEN

Havturbinen er konstrueret med henblik på størst mulige enkelhed, færrest mulige dele, ingen bundkonstruktion ud over fortøjning, nem adgang for reparation.The sea turbine is designed for maximum simplicity, fewest parts, no bottom construction other than mooring, easy access for repair.

Bølgens energi ved opgang og nedgang omsættes i en drejebevæ-gelse via den specielle skrue, forsynet med kileformede blade, der bevirker at skruen bevæges kontinuert med samme omdrej-The energy of the wave upon rise and fall is converted into a pivotal motion via the special screw, provided with wedge-shaped blades, which causes the screw to move continuously with the same rotation.

Claims

-2- DK 94 00381 U3 direction, whether the screw is moved up or down through the water. , The entire ocean turbine is moved together via the wave motion. Thus, mooring alone must be moored for wind and current drift. The described sea turbine is simple, all complicated mechanics, rn.ru. is placed in the float, easily accessible to celebrate inspection or repair. The turbine can be made in many sizes and shapes. It is expected that the spherical shape flows in! the water will give the least tilting effect, thus least disturbing the up and down of the screw. The turbine can act as a single machine or be assembled in series. In the present concept and prototype, the screw is constructed with 4 fixed wedge-shaped blades. Ongoing tests at the Department of Water, Soil and Environmental Engineering Aalborg University Center, supervised by Peter Frigaard, will determine whether 2,3,4 or multi-blade fixed screw or a screw with moving blades and thus switching and energy loss is the best solution. The mooring is equipped with counterweight 6g auxiliary fluids, which must establish a safe mooring with sufficient flexibility to use the wave's rise and fall to the greatest extent possible for energy production. The attached figure shows the float and the intended mooring. The wedge-shaped blade referred to in the specification is herein referred to as triangular drive wheel. A wooden model is attached to the screw principle. A prototype with cylindrical flow is available and is for testing at AUC. UTILITY MODEL REQUIREMENTS. Sea turbine for energy production using wave movements, new in that the entire turbine follows the wave's movements and thus works with the sea - not against it. Enjoy by taking advantage of the relative motion of the surface and its decrease in depth. Enjoy using a wedge-shaped screw with no moving parts. The optimum design of floats and screws cannot be described at present, as it will depend on ongoing tests and in practice must be presumed to be designed according to prevailing wind and current conditions.
