Description

Hydropower generator for slow-flowing waters or as a trailing generator behind a boat, gimballed in a watertight housing above the water surface, connected by a rigidly fixed shaft tube with acting on the generator torque transmitting in medium seawater resistant media-lubricated bearings guided by V-ring sealed housing, in plunging at a shallow angle of approximately 20 degrees by management level, thus compensating for the buoyancy-induced buoyancy, at the end of which a variable velocity propeller converts the kinetic energy of the incoming water into rotation of the remote power shaft, encountering higher speeds and evasion objects Surrounded by a mantle, tapering at shallow angles of variable 100-125 degrees in the lower area to increase the flow, opened by an adjustable baffle, fixed and in point n angle arranged trusses is performed, which is supported from the front and side of the shaft tube and / or mantle, to reduce vertically acting flow forces the shaft tube to reduce the braking action flexibly deflected holding in position, supported by Leitarbene laminar leadership to prevent yawing.

A screw collision by floating foreign bodies, such as lighter flotsam, fiber structure and living things preventing, lets the drive side deflect and slide off the foreign body by the trusses described or a previously attached basket with a grid.

A fixed point with roller translation for a leash is provided in half of the construction for lifting the unit out of the water and calibrating the flow, in addition, the underside of the cladding tube is provided inferior in the housing near holes for draining penetrated water when lifting the unit.

When used as a hydropower generator, the unit is positioned on a float off-stream near the shoreline through mating variable length spacers at right angles to the shore, and upstream through an angularly-positioned resilient jig which leads to the shore for maintenance and in the event of an accidental collision Propellant independently wanted shearing the unit and thus slipping the floating material allows.

The design as a boat generator follows low weight well below 10 kilograms, the simplest construction, low-loss transmission with low driving resistance, which measured measured at a boat about 0.1 knots, and a low susceptibility to interference and easy repair and maintenance options.

Im einfachsten Fall ist das ein geschwindigkeitsregulierendes Getriebe, vorzugsweise mit Zahnriemen durch Andruckvorrichtung gespannt, ggf. mit Planetenradgetriebe. Einfache Übertragung erfolgt durch Verwendung mehrerer Spulen (Drehstrom), um die autonomen Streckenzeiten modernerer Schiffe zu verlängern und deren Strombedarf für Navigation, Autopilot, Licht, Kühlung, Kommunikation und Trinkwasseraufbereitung besser zu decken.Since the flow velocity in a running water is low, as well as behind a sailing boat, which does not exceed its trunk speed *

If the speed of the propeller is limited to 90-160 revolutions / minute depending on the propeller and its setting possibility, the necessary angular speed of the unit of the generator is established by a factor of five according to the type. In the simplest case, this is a speed-regulating gear, preferably tensioned by toothed belt by pressure device, possibly with planetary gear. Simple transmission is achieved by using multiple coils (three-phase) to extend the autonomous travel times of more modern vessels and to better meet their power requirements for navigation, autopilot, light, cooling, communication and drinking water treatment.

The use of solar generators is limited because of the necessary size of the panels of about 4-6 square meters, as well as the use of wind energy converters in terms of effort, support, noise, wind resistance and vibration dynamics and weight, the necessary high construction of these units has a negative impact on the top weight and the Kenterverhalten of the ship.

The invention described is intended to be attached with use as a boat generator with little effort at the stern, in many cases without hull perforation in the vicinity or on the local rescue or bathing ladder without limiting their function, with very little transmission of vibration and noise by vibration.

It self-adjusts itself when driving through the variably adjustable control level in the water and stabilizes about 20 centimeters below the water surface regardless of movements of the ship in the swell, by initially absorbing torque sideways evasive, by Längsleitfläche compensating with the speed. The power is generated over the entire speed range from about 2 knots speed.

The generated current is buffered by an accumulator, possibly by an inverter to another voltage in cooperation brought with other generators or converted into heat.

State of the art

• 1. Große Generatoren für Gezeitenkraftwerke, bei denen Turbine und Generator voll gekapselt und voll eingetaucht einzeln oder in Gruppen zu Wartungszwecken um eine Achse oberhalb der Wasserlinie schwenkbar an Schwimmkörpern oder festen Bauwerken befestigt sind, z. B. Torqado-Patent EP2195524 A1
• 2: An Schwimmkörpern fest montierte Generatoren ,einzeln oder in Gruppen,, bei denen Turbine und Generator ebenfalls voll gekapselt und voll eingetaucht sind, meistens an Gewichten am Fluss- oder Meeresgrund verankert, teilweise als Darreus-Turbine ausgeführt, z. B. Smart power hydro turbine-Patent WO2015000964 A1 , Thropton Energy Services UK, sowie New Energy Corporation Inc, Canada, und Lucid Energy Technologies, UK

• 4. Eine Ausnahme ist ein Generator, der an einem 30 m langen Seil einen durch sein Gewicht balancierten Propeller nachschleppt, (in der Tradition des „Walker-Schlepplogs” als erstem mechanischen Meilenzähler), wobei einerseits die Leine eine große Reibungsfläche bietet, andererseits der Propeller bei langsamer Bewegung des Schiffes nicht mehr effektiv ist, beim Einholen der Turbine verdreht sich die Leine sehr stark, wenn sie nicht meistens vorher durch große Fische abgebissen wurde.
• 5. Eine Sonderstellung nehmen Generatoren ein, welche durch Umrüstung sowohl als Wind bzw. als Hydrogenerator genutzt werden können, hier ist der Generator oberhalb der Wasseroberfläche positioniert und mit einer Ferntriebswelle über Kreuzgelenke bzw. Kegelradgetriebe mit der Turbine bzw. dem Repeller verbunden, ein weiteres Modell ist der sogenannte DuoGen-Generator, welcher auf unsere Anregung von der nachfolgenden Firma entwickelt wurde, hier treibt eine Turbine bzw. ein Repeller, horizontal zur Wasseroberfläche hinter der Turbine an einem Gestänge fixiert, über ein Kreuzgelenk einen Generator am Heck des Bootes an, der Repeller ist hier vor schwimmenden Fremdkörpern nicht geschützt: Eclectic Energy Ltd, UK-Patent nicht gefunden

Essentially, hydrogenerators differentiate into three categories:

• 1. Large generators for tidal power plants, in which the turbine and generator are fully enclosed and fully immersed, individually or in groups, for maintenance purposes, pivotally mounted to floats or fixed structures about an axis above the waterline, e.g. Torqado patent EP2195524 A1
• 2: Generators fixed to floats, individually or in groups, where the turbine and generator are also fully enclosed and fully submerged, usually anchored to weights at the bottom of the river or the sea, sometimes as a Darreus turbine, e.g. B. Smart power hydro turbine patent WO2015000964 A1 , Thropton Energy Services UK, and New Energy Corporation Inc, Canada, and Lucid Energy Technologies, UK
• 3: generators for generating power on sailing yachts: at the stern of the boat turbine and generator are fully enclosed and fully immersed and rotatable about one or two axes and hinged for maintenance purposes. - z. B. Watt & Sea Generator, patent USD671492 S1 from France as Ampair UW underwater generator from England
• 4. One exception is a generator dragging a propeller balanced by its weight on a 30m rope (in the tradition of the "Walker towing log" as the first mechanical mileage counter), with the line providing a large friction surface on the one hand, and the other Propeller slower movement of the ship is no longer effective, when retrieving the turbine, the leash twisted very strong, unless it was bitten off previously mostly by large fish.
• 5. Generators occupy a special position, which can be used by conversion both as a wind or as a hydrogen generator, here the generator is positioned above the water surface and connected to a remote drive shaft via universal joints or bevel gear with the turbine or the repeller, another Model is the so-called DuoGen generator, which was developed on our suggestion by the following company, here drives a turbine or a repeller, horizontally fixed to the water surface behind the turbine to a rod, via a universal joint a generator at the rear of the boat, the repeller is not protected from floating debris: Eclectic Energy Ltd, UK patent not found
