Description
Die Erfindung betrifft einen Schutzkorb für die Antriebsschraube eines Bootsaußenbordmotors, wobei der Schutzkorb in Längs- und Querrichtung angeordnete Gitterstäbe aufweist sowie für eine Befestigung am Schaft des Bootsaußenbordmotors ausgebildet ist, und wobei die Gitterstäbe Profilstäbe sind und strömungsgünstig angeordnet sind.The The invention relates to a protective cage for the drive screw of a Boat outboard motor, wherein the protective cage in longitudinal and arranged transversely arranged grid bars and for a fastening on the shaft of the boat outboard motor is formed, and wherein the grid bars are profiled bars and arranged aerodynamically are.
Es sind Vorrichtungen bekannt, die vor motorgetriebenen Schiffsschrauben angeordnet sind und im Wasser als Strömungsleitkammern zur Messung der Antriebsenergiemengen oder zur Verbesserung der Strömungsverhältnisse dienen.It Devices are known which are in front of motorized propellers are arranged and in the water as Strömungsleitkammern for measurement the amount of drive energy or to improve the flow conditions serve.

Der Erfindung liegt die Aufgabe zugrunde, für die Antriebsschraube eines Bootsaußenbordmotors einen Schutzkorb anzugeben, der ungewollte Berührungen mit der Antriebsschraube während ihres Betriebs verhindert und aus Profilstäben besteht, bei denen die Energieverluste durch den Strömungswiderstand minimal sind.Of the Invention is the object of the drive screw of a Boat outboard motor one Specify protective cage, the unwanted contact with the drive screw while their operation and consists of profiled bars, in which the Energy losses through the flow resistance are minimal.
Diese Aufgabe löst die Erfindung durch einen Schutzkorb gemäß dem Patentanspruch.These Task solves the invention by a protective cage according to the claim.
Mit dem erfindungsgemäßen Schutzkorb wird ein hinreichender Schutz vor Berührungen mit der Antriebsschraube und damit vor Unfällen und sonstigen Schäden erreicht. Die Auswertung bisheriger Unfälle mit Menschen im Badebetrieb, die zunehmend auftreten, hat zur Entwicklung des Schutzkorbs der Erfindung geführt.With the protective basket according to the invention is adequate protection against contact achieved with the drive screw and thus against accidents and other damage. The evaluation of past accidents with people in the bathing enterprise, which occur increasingly, has to the development the protective cage of the invention out.
Der Schutz vor einer Berührung mit der Außenbordmotorschraube wird mit dem erfindungsgemäßen Schutzkorb in Form einer Profilstabkonstruktion gelöst, die eine Einwirkung von außen auf die motorgetriebene Schraube verhindert. Das Kennzeichen des Schutzkorbs besteht darin, dass die Profilstäbe einen ellipsenförmigen Querschnitt aufweisen und dadurch die Energieverluste, die durch den Strömungswiderstand vor der Schraube auftreten, minimal sind. Der Schutzkorb ist als eine zwar weitmaschige, aber geschlossene Einrichtung ausgebildet, so dass eine Berührung der Außenbord motorschraube mit Fremdkörpern, insbesondere mit Menschen, Tieren und Pflanzen, verhindert wird.Of the Protection against a touch with the outboard engine screw is with the protective basket according to the invention solved in the form of a profile bar construction, which has an effect of Outside on the motor-driven screw prevented. The mark of the Protection cage is that the profile bars an elliptical cross-section and thereby the energy losses caused by the flow resistance occur in front of the screw, are minimal. The protective cage is as Although a wide-meshed, but closed device trained so that one touch the outboard motor screw with foreign bodies, especially with humans, animals and plants.
Der ellipsenförmige Querschnitt der Profilstäbe des erfindungsgemäßen Schutzkorbs ist den Sog- und Abströmverhältnissen optimal angepasst. Jeder Profilstab des Sicherheitskorbes wird in seiner Längsrichtung, entsprechend der Nutzung des ellipsenförmigen Querschnittes für eine Reduzierung der Energieverluste, derart verdreht, dass er an die Strömungsverhältnisse angepasst ist.Of the ellipsoidal Cross section of the profile bars the protective basket according to the invention is the suction and outflow conditions optimally adapted. Each profile bar of the safety basket is in its longitudinal direction, according to the use of the elliptical cross-section for a reduction the energy losses, twisted so that it depends on the flow conditions is adjusted.
Ein Ausführungsbeispiel eines erfindungsgemäßen Schutzkorbs für den Betrieb von Auißenbordmotorschrauben ist in der Zeichnung dargestellt. Es zeigenOne embodiment a protective basket according to the invention for the Operation of outboard motor screws is shown in the drawing. Show it
Die Erfindungsmerkmale können wie folgt zusammengefasst werden:
- 1. Der Schutzkorb an Außenbordmotorschrauben schützt im Schiffsbetrieb vor ungewollter Berührung durch Mensch, Tier sowie Fremdkörpern und somit sowohl vor Unfällen als auch vor Zerstörungen der Schiffsschraube.
- 2. Die Gitterstäbe und deren Anordnung in Sog- und Abströmrichtung sind geometrisch so ausgebildet, dass ein energiearmer Betrieb gewährleistet ist.
- 3. Der Schutzkorb eignet sich für alle Schiffs- und Bootstypen mit Außenbordmotorschrauben in allen Gewässern, da er jedem Außenbordmotorschraubentyp und jeder Außenbordmotorschraubengröße angepasst werden kann.
- 1. The protective cage on outboard motor screws protects in ship operation against accidental contact by humans, animals and foreign bodies and thus both from accidents and from destruction of the propeller.
- 2. The bars and their arrangement in suction and outflow are geometrically formed so that a low-energy operation is ensured.
- 3. The protective cage is suitable for all types of ships and boats with outboard motor screws in all waters, as it can be adapted to any outboard motor screw type and any outboard screw size.
