Abstract

The half housing has a plate housing, where the plate housing is arranged perpendicular to a rod. A semicircle of a turbine brings the required performance while another semicircle stays against the flow and hinders the turning of the turbine. The half housing is adjusted around the perpendicular axis of the turbine corresponding to the flow direction.

Description

Technisches Gebiet und ProblematikTechnical field and problems

Die Erfindung gehört zur Technologie der Stromerzeugung von den Wasserströmen (Gezeiten der Meere, Flüsse). Es wird in der Hydroenergie eingesetzt.The invention belongs to the technology of power generation from the water currents (tides of the seas, rivers). It is used in hydro-energy.

Diese Erfindung ermöglicht eine umweltfreundliche Stromerzeugung von den Wasserströmen ohne Hilfe von komplexen hydrotechnischen Installationen (Dämme, Schleusen usw.)This invention enables environmentally friendly power generation from the water streams without the aid of complex hydro-technical installations (dams, locks, etc.)

Ein Unterscheidungsmerkmal der Wasserturbine „Schnecke” ist ein Halbgehäuse, welches die hemmende Wirkung des Wasserflusses beim Umfließen der Turbine verhindert. Dieses Halbgehäuse ist der Objekt des Patentanspruches.A distinguishing feature of the water turbine "worm" is a half-housing, which prevents the inhibiting effect of water flow when flowing around the turbine. This half-housing is the object of the claim.

Beschreibung der ArbeitsweiseDescription of the operation

Die Turbinen „Schnecke” werden in den Wasserströmen der Flüssen (sowohl in der Strandnähe als auch im Laufe des Flusses, solange es nicht dem Flussverkehr stört) in der Horizontallstellung installiert. Das Halbgehäuse der Turbine liefert eine Drehung der Turbine, welche sich in einem Wasserstrom befindet, der die Turbine von den beiden Seiten umfließt. Bei der Turbineninstallation in der Gezeitenkraftwerken können es zwei Verfahren zur Turbinendrehung in der Stromrichtung (Zufluss oder Ebbe) benutzt werden:

  • a) Eine automatische Umdrehung des Gehäuses um 180 Grad, die die Drehung der Turbine sowohl beim Zufluss als auch bei der Ebbe in dieselbe Richtung ermöglicht.
  • b) Ohne eine automatische Umdrehung aber mithilfe einer automatischen Umschaltung der Generatorpolen
The turbines "snail" are installed in the water flows of the rivers (both near the beach and in the course of the river, as long as it does not disturb the river traffic) in the horizontal position. The half-shell of the turbine provides a rotation of the turbine, which is located in a stream of water, which flows around the turbine from the two sides. In turbine installation in tidal power plants, two methods of turbine rotation in the flow direction (inflow or low tide) may be used:
  • a) An automatic rotation of the housing through 180 degrees, which allows the rotation of the turbine in both the inflow and the ebb in the same direction.
  • b) Without an automatic rotation but with the help of an automatic switching of the generator poles

Die Turbine „Schnecke” werden auf der Senkrechten Achse (1) installiert (siehe Skizze I). Auf dieser Achse ist auch ein Turbinenstator (2). Ein Turbinenrotor ist mit dem inneren Rand der Turbine verbunden (4). (2), (3) und (4) stützen sich auf den Stützlager der Turbine (7), welcher sich auf die Stützplatte stützt (8). Das Halbgehäuse (9) der Turbine stützt sich auf die Gehäusestützplatte (10), die an der senkrechten Stange installiert wird.The turbine "snail" are on the vertical axis ( 1 ) (see sketch I). On this axis is also a turbine stator ( 2 ). A turbine rotor is connected to the inner edge of the turbine ( 4 ). ( 2 ) 3 ) and ( 4 ) are based on the support bearing of the turbine ( 7 ), which rests on the support plate ( 8th ). The half-casing ( 9 ) of the turbine rests on the housing support plate ( 10 ), which is installed on the vertical bar.

Anwendungsbeispieleapplications

Die Turbinen „Schnecke” können sowohl in die Höhe (in der Abhängigkeit von der Stromtiefe) als auch in die Reihen gruppiert werden. Sie können auch für verschiedene Leistungskapazitäten projektiert werden. Die Wasserturbinen „Schnecke” werden je nach der Tiefe des Wasserflusses in mehreren Schichten senkrecht als auch in mehrere Reihen je nach der Breite und Länge des rational benutzen Wasserflusses eingestellt.The "worm" turbines can be grouped both in height (depending on the current depth) and in the rows. They can also be configured for different power capacities. Depending on the depth of the water flow, the "snail" water turbines are set in several layers vertically as well as in several rows according to the width and length of the rationally used water flow.

Die Installationsstellen der Wasserturbinen „Schnecke” werden auf der Wasseroberfläche mit Hilfe von warnenden Bojen markiert. Für den Schutz der Tierwelt können die Ultraschaltsignale in der Turbinenzonen eingesetzt werden.The installation points of the water turbine "snail" are marked on the water surface with the help of warning buoys. For the protection of the animal world, the ultrasonic signals can be used in the turbine zones.

Claims (1)

Die Neuheit der Erfindung ist die Benutzung eines Halbgehäuses zur Beseitigung der hemmenden Wirkung des Wasserströmes auf einen Halbkreis der Turbine. Nur ein Halbkreis der Turbine kann die nützliche Leistung bringen, während der zweite Halbkreis steht dem Strom entgegen und verhindert die Turbinendrehung. Das Halbgehäuse dient zur Abdeckung von diesem unnützlichecn Halbkreis der Turbine. Das Halbgehäuse kann durch eine Drehung um die senkrechte Achseder Turbine (siehe Skizze I) entsprechend der Stromrichtung eingestellt werden. Diese Eigenschaft ist besonders wichtig für die Turbineninstallation in Gezeitenströmen.The novelty of the invention is the use of a semi-casing to eliminate the inhibiting effect of the water flow on a semicircle of the turbine. Only a semicircle of the turbine can bring the useful power, while the second semicircle is opposed to the current and prevents the turbine rotation. The half-case serves to cover this useless semicircle Turbine. The half-housing can be adjusted by a rotation about the vertical axis of the turbine (see sketch I) according to the current direction. This feature is especially important for turbine installation in tidal currents.
