Abstract

The blades of a wind wheel touch the water surface at the outer diameter, that is at the position of their highest rotary speed. At an appropriate frequency of rotation of the blades, the water is ejected, so that the water/air exchange surface is increased and thus the oxygen content of the water is increased. In order to increase the contact surface in the water, a second wind wheel is located behind the first. These two wind wheels are connected at the outer diameter by an angle iron. There are no running costs for this apparatus which is not liable to break down. Application in the fish industry, for garden ponds and plastic sheeting ponds and to improve the self-purification capacity of bodies of water.

Description

Beschreibung, (zu Abb. 1):Description, (to Fig. 1):

Die Erfindung betrifft eine Konstruktion, mit der dem Wind Bewegungsenergie entnommen wird, diese Bewegungsenergie wird a m W i n d f 1 ü g e 1 s e 1 b s t genutzt um Wasser in Tropfenform aufzuteilen. Durch diese Aufteilung wird die Be= rührungsfläche Wasser - Luft vergrößert und somit der Sauer= stoffgehalt des Wassers erhöht.The invention relates to a construction with which the wind kinetic energy is taken, this kinetic energy is a m W i n d f 1 ü g e 1 s e 1 b s t used to divide water in the form of drops. Through this division the Be = The water-air contact area is enlarged, and thus the oxygen content of the water elevated.

Das Belüftungsgerät ist folgendermaßen aufgebaut.The ventilation device is structured as follows.

Ein korrosionsbeständiger Rahmen in rechteckiger Form wird durch Schwimmkörper auf der Wasseroberfläche gehalten. Unter diesem Rahmen ist ein senkrechtes Rohr befestigt, welches einen Ankerpunkt (Pfahl, Gleitrohr) umgibt und so unterschied liche Wasserstandshöhen ausgleicht. Auf diesem Rahmen ist in einer bestimmten Höhe eine zwei-fach gelagerte Welle befestigt.A corrosion-resistant frame in a rectangular shape is made by floating bodies kept on the water surface. Under this frame is a vertical pipe attached, which surrounds an anchor point (pile, sliding tube) and so differentiated compensates for water levels. On this frame is at a certain height a shaft with two bearings is attached.

Jeweils an Anfang und Ende der Welle ist ein Windrad angebracht.A wind turbine is attached at the beginning and end of the shaft.

Die Befestigungshöhe der Welle ist ca. die Hälfte des Windrad= durchmessers. Die Windflügel sind an der Stelle ihrer größten Umfangsgeschwindigkeit in das Wasser eingetaucht. Um die Berühr= ungsfläche im Wasser zu vergrößern, sind jeweils die Enden der Windflügel mit einem Leichtmetall - Profil verbunden.The mounting height of the shaft is about half the diameter of the wind turbine. The wind blades are in the water at their greatest peripheral speed immersed. To increase the contact area in the water, the The ends of the wind blades are connected to a light metal profile.

Die Eintauchtiefe dieses Profils richtet sich nach: 1. Durchmesser des Windrades 2. Anzahl der Flügel 3. Verhältnis von Windraddurchmesser zum Abstand des zweiten Windrades (Abb. 1) 4. Breite des Wirbelprofils ( Abb. 2 und 3 ) Die Eintauchtiefe sollte so bemessen sein, daß schon bei geringer bis mittleren Windgeschwindigkeiten das Drehmoment der Wind flügel ausreicht, um Wassermengen aufzuschleudern. Wie sich bei einem ersten Modell gezeigt hat, ist für das ins Wasser enge= tauchte Profil schon ein Aluminium Winkel Material ausreichend, das keiner weiteren Verformung bedarf. Um jedoch schon bei geringen Windgeschwindigkeiten eine Aufwirbelung des Wassers zu erreichen, können Bohrlöcher im Winkel- Profil enthalten sein, Zweck des Belüftungsgerätes: 1. Direkte Nutzung der Windenergie zur Wasserbelüftung 2. Schaffung eines Belüftungsgerätes in robuster und wenig reparaturan fälliger Bauweise 3. Herabsetzung der Investitionskosten der Wasserbelüftung in der Teich- und Fischwirtschaft. Da für dieses Gerät kosten= lose Windenergie zur Verfügung steht, können die Betriebs= kosten zur Wasserbelüftung gesenkt werden (Zusatzbelüftung).The immersion depth of this profile depends on: 1. Diameter of the wind turbine 2. Number of blades 3. Ratio of the wind turbine diameter to the distance of the second wind turbine (Fig. 1) 4. Width of the vortex profile (Fig. 2 and 3) The The immersion depth should be such that even at low to medium wind speeds the torque of the wind blades is sufficient to throw up amounts of water. How yourself has shown in a first model, is for the narrow profile in the water = immersed in the water even an aluminum angle material is sufficient that no further deformation requirement. However, in order to whirl up the To reach water, boreholes can be included in the angle profile, purpose of the ventilation device: 1. Direct use of wind energy for water ventilation 2. Creation of a ventilation device in a robust and easy to repair design 3. Reduction of the investment costs for water aeration in the pond and fish industry. Since free wind energy is available for this device, the operating = costs for water aeration are reduced (additional ventilation).

4. Wasserbelüftung für Garten- und Folienteiche.4. Water aeration for garden ponds and liner ponds.

Durch das Belüftungsgerät wird gleichzeitig der Freizeitwert dieser Teiche erhöht. The ventilation device also increases the recreational value of this Ponds increased.

5. Verbesserung der Selbstreinigungskraft der Gewässer.5. Improvement of the self-cleaning power of the waters.

Alle bekannten Belüftungssysteme werden zum Teil mit erheblichen laufenden Unterhaltskosten betrieben. Die bekannten Belüftungs= systeme mit Windenergie arbeiten über Druckluftkompressorn bzw.All known ventilation systems are in part with considerable running Maintenance costs operated. The known ventilation systems work with wind energy via air compressor or

Pumpen oder über Umlenkgetriebe und Umlenkrollen.Pumps or via deflection gears and deflection pulleys.

Der Erfindung lag die Aufgabe zugrunde die Belüftung durch Wind energie mit möglichst geringen Kosten zu gestalten. So sollten an das Belüftungsgerät keine Zusatzeinrichtungen gekoppelt sein.The invention was based on the problem of ventilation through wind energy at the lowest possible cost. So no Additional devices be coupled.

Das Windrad und das Gerät zur Belüftung stellen eine Einheit dar.The wind turbine and the device for ventilation represent a unit.

Die Wasserbelüftung durch Windenergie ist damit auf die größte Einfachheit bezüglich der Konzeption gebracht. Hierdurch werden Wartungs- und Reparaturarbeiten auf ein Kleinstmaß verringert.The water aeration by wind energy is thus at the greatest simplicity brought about the conception. This eliminates maintenance and repair work reduced to a minimum.

In Gewässern, die teilweise verschmutzt sind, trägt der erhöhte Sauerstoffgehalt dazu bei die Selbstreinigungskraft des Wassers zu erhöhen. Durch den größeren Sauerstoffgehalt können Bakterien= kulturen, die diese Verunreinigungen vernichten zu größerer Aktivität angeregt werden. Dieses gilt sowohl für verschmutzte Gewässer, wie auch für Gewässer mit Fischhaltung.In waters that are partially polluted, the increased oxygen content contributes to increase the self-cleaning power of the water. Because of the greater oxygen content bacteria = cultures that destroy these impurities can lead to greater activity be stimulated. This applies to both polluted bodies of water and bodies of water with fish farming.
