Abstract
Description
♦♦
Voortstuwer zonder waterweerstandPropeller without water resistance
De uitvinding heeft betrekking op het verkrijgen van minder waterweerstand van de middelen waardoor een object wordt verplaatst S of gepositioneerd in het water, wanneer deze niet in gebruik zijn en het object wordt bewogen door andere middelen.The invention relates to obtaining less water resistance of the means whereby an object is displaced or positioned in the water when these are not in use and the object is moved by other means.
Volgens de uitvinding kan dit worden bereikt door deze voortstuwingsmiddelen intrekbaar te maken, wanneer deze niet in gebruik zijn* zodat deze binnen de romp van het vaartuig komen. Dit 10 is mogelijk door een elastische afsluiting die de benodigde verticale beweging voor de intrekking van de voortstuwer mogelijk maakt en zorgt voor een simpele waterdichte verbinding. Een afsluitplaat kan worden toegevoegd om het gat af te sluiten.According to the invention this can be achieved by making these propulsion means retractable when they are not in use * so that they come within the hull of the vessel. This is possible due to an elastic closure that allows the required vertical movement for the retraction of the propeller and provides a simple watertight connection. A closing plate can be added to close the hole.
15 De uitvinding zal hieronder nader worden uiteengezet aan de hand van de figuren.The invention will be explained in more detail below with reference to the figures.
Figuur 1 toont de voortstuwer (1) uitgestoken onder de romp (2) van het vaartuig. Het elastische membraan (3) is aan een zijde verbonden met de romp van het vaartuig (4) en aan de andere zijde 20 middels een ring (5) verbonden met de behuizing van de voortstuwer(6). Het binnenhuis (7) met lagering en vertanding (8) kan eventueel zo uitgevoerd worden dat het kan draaien om het intrek mechanisme (9) waarbij een extra afdichting en lagering (10) geplaatst kan worden ter plaatse van de opening. Deze opening kan 25 worden afgesloten met afdichtingdeksel (11).Figure 1 shows the propeller (1) protruded under the hull (2) of the vessel. The elastic membrane (3) is connected on one side to the hull of the vessel (4) and on the other side is connected by means of a ring (5) to the housing of the propeller (6). The inner housing (7) with bearing and toothing (8) can optionally be designed such that it can rotate around the retraction mechanism (9), whereby an additional seal and bearing (10) can be placed at the location of the opening. This opening can be closed with sealing cover (11).
Figuur 2 toont de voortstuwer ingetrokken wanneer niet in gebruik. De bergruimte voor de stuwmotor is nu afgesloten door afdichtingdeksel (11). De geleidingspalen (12) geleiden de samenstelling tijdens de beweging. De voortstuwer kan aangedreven 30 worden door een elektrische motor, een hydraulische motor, of een diesel motor. De motor (13) kan direct op de voortstuwer geplaatst worden maar dit hoeft niet zie figuur 3.Figure 2 shows the impeller retracted when not in use. The storage space for the propulsion engine is now closed by the sealing cover (11). The guide posts (12) guide the assembly during the movement. The propeller can be driven by an electric motor, a hydraulic motor, or a diesel motor. The motor (13) can be placed directly on the propeller, but this is not necessary, see figure 3.
Figuur 3 toont de voortstuwer aangedreven door een diesel motor (14). De horizontale as (15) zorgt voor de verbinding tussen 35 onderwater tandwielkast (16) en de motor. Voor ophalen kan de motor worden losgekoppeld via hefboommechanisme (17).Figure 3 shows the propeller driven by a diesel engine (14). The horizontal shaft (15) provides the connection between the underwater gearbox (16) and the motor. For retrieval, the motor can be disconnected via lever mechanism (17).
