Description

Wind-powered boat or vessel. - The vindkraften gaende bat eller farkost.

Navigating a sailboat or sailing ship requires considerable skill in handling sails. In addition, good physical condition is needed. The high sail mast also restricts movement under bridges. Charging backup batteries is also problematic.

The object of the invention is to provide a new type of wind-powered boat or vessel which can be sailed in the same way as conventional sailboats or vessels, but which does not have the above-mentioned disadvantages.

This object is achieved by the invention on the basis of the features set out in the appended claims.

An embodiment of the invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a boat or vessel according to the invention seen from the side and Figure 2 shows a structural detail of Figure 1 on a larger scale.

Figure 3 shows a top view of a boat or vessel according to the invention, the different angles of adjustment of the rotation plane of the wind turbine being shown by lines A, B and C.

Figure 4 shows a front view of the wind turbine.

In the case shown, there are two seats 2 for sailors in the hull 1 of a boat or ship. Since the invention does not require strings for controlling the sails, the sailors 'positions 2 can be covered by a canopy 3. A vertical mast 4, 2 86831 is attached to the frame 1 in front of the sailors' positions 2. At its upper end a wind turbine 5 is mounted for rotation about a horizontal axis 6.

In the case shown, the wind turbine 5 may be in the form of a typical propeller used in wind turbines, which, as seen from the front, has a general shape similar to that shown in Fig. 4. For example, the in a two-seater boat, the blade length of the wind turbine 5 can be 2 m, whereby the rotor 5, when rotating, covers the area of a circle with a diameter of 4 m. The wind pressure on such a wind turbine is already several tens of kilograms at normal wind speed. Made of plastic, such a propeller typically weighs only about 4 kg. The shaft 6 is rotatably mounted on lugs 7 attached to a vertical sleeve 8 which is rotatably mounted by bearings 9 around the upper end of the mast 4. Attached to the mast 4 is a servomotor 10 which is arranged by means of a toothed belt 11 to rotate the tube 8 about a vertical axis. In this case, the vertical plane of rotation of the wind propeller 5 also rotates or rotates about the vertical axis.

The rotational force of the propeller 5 is transmitted from the shaft 6 by bevel gears 12 to the vertical shaft 13 and further by bevel gears 14 to the horizontal shaft 15, to the outer end of which a propeller 16 is attached to the stern of the boat, shaped and dimensioned to act as a water propeller. Propeller 16 may need to be replaced so that a larger propeller can be selected in low winds.

Associated with the shaft 15 is a disc brake 17, by means of which the sailor can, for example by depressing the foot pedal, brake the rotation of the propeller 5 and, if necessary, lock the propeller 5 non-rotating. The ratio between the rotational speeds between the propellers 5 and 16 can be selected in the gear 18. The bevel gears 12 and 14 can provide the necessary promotion gear. As it rotates, the wind propeller 5 also rotates a generator 19, which charges the battery 20, from which electric current is obtained e.g. for servomotor 10.

Essential to the invention is the possibility of turning the plane of rotation of the wind turbine 5. As a result, the boat or vessel according to the invention is made to operate in different wind conditions in substantially the same way as a sailing vessel. When the direction of the wind is from the rear, the plane of rotation of the propeller 5 is set substantially perpendicular to the direction of the wind, whereby the rotor 5 acts as both a pusher and a rotator of the water propeller 16 as it rotates. When the wind direction is from the side, the level of rotation of the propeller 5 is adjusted to an acute angle with the wind direction (e.g. level C in Fig. 3), whereby the wind further effectively rotates the propeller, which also has a forward component with thrust. Thus, the operation of the wind propeller 5 in a dual function is also achieved with the crosswind; to act as a sail surface and propeller 16 for the water propeller. This combined effect is also achieved in crosswind winds, the only limitation being that the angle between the plane of rotation of the propeller and the wind does not become so small that the rotational power of the propeller decreases sharply.

The plane of rotation of the wind turbine 5 can be arranged to be rotated 360 ° without restriction. In this case, the safety of the sailors must be ensured by arranging a sufficient distance between the positions 2 and the nearest location of the tip of the propeller 5. The use of a protective hood 3 also increases safety, as it prevents the sailor from, for example, extending his hand to the possible trajectory of the propeller 5. One possibility is to limit the rotation of the rotation plane of the propeller 5 between the planes A and B shown in Fig. 3, whereby the rotation plane of the propeller does not reach above the positions 2. If the plane of rotation of the propeller 5 is brought far enough away from the mast 4, this limited turning arrangement can also cover a 180 ° turning possibility.

When under bridges, the propeller 5 can be locked in a horizontal position by a brake 17. In this case, it is possible to drive forward by rotating the propeller 16 by a generator 19 used as a motor with the power of a battery 20.

When the boat or vessel is stationary, the propeller 5 charges the batteries 20. The boat or vessel can be anchored so that it always turns in the direction of the wind due to the wind pressure.

The boat or vessel 1 must be equipped with a keel from the sailboat in a known manner. Since lateral wind pressures tend to tilt the boat or vessel strongly, it is advantageous to implement the invention with bow nails 21 on both sides of the boat or vessel. In the case shown, the pontoons 21 are attached to the ends of the horizontal arm 22. The arm 22 is arranged to be pivoted about a horizontal axis 23, preferably by electric power, e.g. by a servomotor. When the wind pressure tilts the vessel, the sailor can turn the boom 22 by pressing a button and thus correct the tilt of the hull 1 of the vessel. Likewise, by pressing a button and following the speedometer, the sailor can find the most advantageous angle for the plane of rotation of the propeller 5. Thus, sailing is easy and effortless and does not require professional skills. Thanks to the canopy 3, the sailor also does not get wet at sea.

One feature of the invention is that a reverse gear is not necessarily required, but by rotating the rotation plane of the propeller 5 180 °, the water propeller 16 is caused to rotate in the reverse direction.

The invention is, of course, not limited to the embodiment described above. Thus, for example, the mechanical transmission between the propellers 5 and 16 can be replaced by an electric or hydraulic transmission. The rotation of the plane of rotation of the propeller 5 performed by the servomotor 10 can also be arranged to be performed mechanically, e.g. by rotating the hand cranks. The mast 4 can be replaced by, for example, a lattice frame. Many other structural changes are possible within the scope of the following claims.

When testing the invention in practice, it has been found that the vessel travels directly into the headwind when the axis of rotation of the air propeller is parallel to the vessel and the wind.
