Description

Technical field

The technical solution relates to a rotary generator of mechanical energy obtained from slow-flowing media -III.

BACKGROUND OF THE INVENTION

In both natural and industrial environments, there are sources of slowly flowing media in liquid or gaseous form. These are mainly moving masses of air and water. The energy of water, mainly from its slope or flow (with a small proportion of sea tides), today provides about a fifth of the world's electricity produced. However, it contributes more than three fifths to the contribution to mankind's electricity balance from sustainable sources. Sometimes it is not considered a full source, as large hydroelectric power plants require the construction of massive dams with lakes, which inevitably has a significant negative impact on the environment. However, since all factors must always be considered for energy sources, it can be said that hydro-energy sources clearly outweigh the benefits of fossil fuels. However, the efficient operation of virtually all water turbines requires a relatively high flow rate, above approximately nine kilometers per hour. Most watercourses do not even reach five kilometers per hour. This represents a problem and an obstacle to the development of the energy industry - worldwide and in Slovakia. Although our country is mountainous, it has much less flow than Austria. Switzerland or Norway, the European hydropower powers. Its hydro-energy potential is already utilized by about two thirds. With higher prices of fossil fuels and growing awareness of how they are burdening the environment, there is also increasing pressure in Slovakia to build new hydro-energy capacities in sections of streams with a greater slope. However, almost all of them are located in ecologically-landscaping, socially and touristly valuable locations. Deeper reasoning here prefers not to sacrifice further sections of the country. It is not everywhere that the water can be appropriately embedded in the natural scenery. It is therefore necessary to address the exploitation of the energy potential of slowly flowing media. t. j. water and air.

The essence of the technical solution

These drawbacks are largely eliminated by the proposed technical solution, which is based on the fact that the flow of slowly flowing medium (eg water, air) is placed in a well shaped swivel surface (eg a wing with a rectangular plan), which is opposite to the direction of movement. media inclined at an appropriate angle. Due to the interaction of the medium flow, the swinging surface (wing) will, in accordance with the laws of hydrodynamics (aerodynamics), exert a force on the arms to which the surface is rotatably mounted by the holder and will carry them in the direction of the applied force. The drive arm will carry the connecting rod, which will cause the flywheel to rotate through the crankshaft. The movement of the connecting rod and its pulling force will depend on the size of the swinging surface (wing) and the speed of the flowing medium. The inclination of the swivel surface relative to the flow of the flowing medium is ensured by the asymmetrical positioning of the pivot axis of the swivel surface, the shape of the holder and the position of the stops of the extreme positions of the surface. The angle of inclination of the swivel surface relative to the direction of flow of the medium is determined by the geometric dimensions of the holder and is stabilized by the medium flow itself. This current, due to the asymmetric distribution of the respective part of the swivel surface relative to its axis of rotation, generates two unequal torques acting against each other. As a result, the swivel surface rotates in the medium flow in the direction corresponding to the difference of these moments t. j. in the direction of greater torque. The pivot surface remains in such a stable position and, by means of the holder, transmits the force acting on the pivot surface through the flowing medium to the drive arm. This rotates the flywheel through the connecting rod, which accumulates and balances the flow of energy from the flowing medium. In the extreme positions of the swivel surface position, the direction of the applied force and thus also the direction of movement of the swivel surface and arms changes as a result of the swivel surface leaning against one of the position stops. As a result of the further original movement of the swivel surface, it is tipped over. Consequently, this new position of the swivel surface becomes stable under the action of the flowing medium. At the same time, it starts to move in the opposite direction and thus carries the holder and drive arm. The direction of motion of the flywheel will not change and its movement energy will support the roll-over. The swivel surface in the new position will move in the fluid stream until it rests against the stop, the position on the opposite side. There, the swivel surface will automatically tip over again and this process will be repeated cyclically. This ensures a continuous, rocking movement of the arms as well as the movement of the connecting rod and the rotation of the flywheel, whose shaft carries the output mechanical energy. The advantage of this technical solution is that it enables the transformation of the moving energy of slowly flowing media into mechanical energy in a technically simple way, without the need for expensive materials and demanding technological procedures. The device is functional in both horizontal and vertical position of the swing surface. Flywheel (or flywheel with pre2)

SK 5970 Υ1 water supply) ensures accumulation and even supply of mechanical energy. Energy is transformed by high efficiency equipment. The device allows to utilize the energy of previously unused slow flowing media, where the use of turbines and other previously used devices is not possible. In the case of slow flowing water, it is about 70% of the moving water masses worldwide. The device is suitable for inland waterways, but also for use of sea currents, tides and other flows. It can work at the bottom of the streams, but also just below the surface of the vessel. It does not require fast flow, nor turbines or dams. It also suffices with a flow below 3.5 km / h (eg 2.5 km / h), making it possible to exploit the untapped hydroenergy potential of most of the world's rivers and seas.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 shows an embodiment of the invention. The rotary generator of mechanical energy obtained from the slowly flowing media has swiveling surfaces 1 positioned upstream of the flowing media. Due to hydrodynamic or aerodynamic forces, the swivel surfaces 1 are displaced perpendicular to the direction of the moving medium. The direction of movement of the pivoting surfaces 1 is adjusted and changed by their inclination. The source of mechanical energy is the moving medium and the mechanical energy is taken up by the swinging surfaces 1, which perform a rocking movement, carrying the holder 2, which is rotatably connected to the arm 3 and the driving arm 4 by bearings 25 and pins 16. The drive arm 4 is pivotally connected to the beams 5 via a pin 15 and a bearing 24 with a connecting rod 6 with a pin 14 and a bearing 21. The swivel surfaces 1 (wings) will be due to the interaction of the medium flow exert a force on the arms 3, 4 to which the swivel surfaces 1 are pivotably fastened by means of the holder 2 and will carry them in the direction of the applied force. The drive arm 4 will carry the connecting rod 6, which will be moved by it. the crankshaft 13 cause the rotary movement of the flywheel 8. The movement of the connecting rod 6 and its thrust force will depend on the size of the swivel surfaces 1 and the flow velocity of the flowing medium. The inclination of the swivel surfaces 1 against the flow of the flowing medium is ensured by the asymmetrical positioning of the beam 12 (axis of rotation) of the swivel surfaces I, the shape of the holder 2 and the position of stops H of the extreme positions of the swivel surfaces L it is stabilized by the medium flow alone. Due to the asymmetrical distribution of the respective part of the swivel surface I relative to the axis of rotation of the beam 12, this current generates two unequal torques acting against each other. As a result, the swiveling surfaces 1 rotate in the medium flow in a direction corresponding to the difference of these moments t. j. in the direction of greater torque coming from most of the swivel surfaces t Swivel surfaces i remain in such a stable position by means of a holder 2 which transmits to the drive arm 4 an appropriate force due to the effect of medium flow on the swivel surface 1. and the crankshaft 13 rotates the flywheel 8, which accumulates and balances the flow of mechanical energy from the flowing medium. In the extreme positions of the swiveling surfaces 1 (Fig. 2), the direction (reversals) of the applied force and thus also the direction of movement of the swiveling surfaces I and arms 3, 4 is changed. support for the tilting of the swivel surfaces. The swivel surfaces 1 in the new position will move in the medium stream until they rest against the stop of the position 11 on the opposite side. There, the swiveling surfaces 1 are automatically tipped over again and their direction of movement is changed. This process will be repeated cyclically. Thereby, the continuous, rocking movement of the arms 3, 4, as well as the bidirectional displacement of the connecting rod 6 and the rotation of the flywheel 8 are still in the same direction, its crankshaft 13 carrying the output mechanical energy. Between the crankshaft 13 and the flywheel 8, a gearbox (fast) may be placed, in which case the flywheel 8 may have other geometrical dimensions (smaller diameter and weight) and its output shaft may provide more suitable speed and torque for the connected load.
