Abstract

The under water power machine has a control apparatus housing (7) and a hydro-aggregate housing (9) which, together, have a receiver chamber for at least one electrical building element (8, 30, 40) with a jacket (15A). The electrical building element has a seal in the vicinity of its contact surfaces relative to the receiver chamber. There is a single seal (45, 46, 47) in the region of the contact surfaces between the jacket of the electrical building element and the control apparatus housing. The seal may be radially arranged around a region of the connection area (10, 20, 28) of the building element with the hydro aggregate housing or the control apparatus housing sides of the receiver chamber (12).

Description

The The present invention relates to an underwater engine, River or tidal power plants consisting of a shaft to be fixed in the ground which has at least one perpendicular to its axis preferably circular disk, at the two, preferably four horizontal axes in corresponding perpendicular to Wave arranged indentations are mounted, each of the at least two axes with at least one pivotable by approx. 90 ° Shovel is provided below its axis by one or more Counterweights are balanced, so that the counterweight opposite edge the shovel at rest first against the fluid flow is directed and with respect to the disc at an acute angle occupies to a circulation of the disc by the pressure of the fluid flow in an angle up to about 90 ° to unfold on the disc, the disc equipped with buffers that is, the emerging forces at Unfolding the blades intercept the unfolding energy Save to them when folding the blades in the flow direction again leave.

Combustion engines, have the blades falling apart or collapsing or blades, are known from the prior art.

A Invention from the Middle Ages deals with horizontal Slices on which blades or wings were attached, the should set up in the wind. The erect position was through Leather straps held. Turned the wings against the wind, should they are flipped back to the disk by the wind energy, until around to stand upright in the wind to resist.

Since this "design idea" by Fausto Veranzio did not work with counterweights, which put the wings in a state of rest even without wind in a horizontal position, this invention did not work and was therefore not used (source: Roland Gööck, Inventions of Humanity, p. 31 ).

Out US 1,360,222 Furthermore, a wind turbine is known that works with hinged wings. The wings were here constructed so that they consisted of two arranged in pairs on an axis wing leaves, which, when they pointed against the flow direction, unfolded, and enclosed an obtuse angle of about 180 °.

An approximately same construction points DE 199 32 006.3 with the only difference being that it is not designed as a wind turbine but as a hydroelectric power plant.

Of the Disadvantage of these presented engines consists primarily in that they can only be used in areas that a relatively strong fluid flow exhibit. The wings / shovels do not tilt back out of their original position, but instead only because of the counteracting forces of the fluid flow. There the wings from hibernate against the current, then tip over they consume unnecessary Energy, so that the efficiency or the energy yield of the already proposed wind and hydroelectric power plants with folding wings / blades extremely low is.

inventor job It was therefore, to develop an engine that would use of folding blades without energy loss possible by moving the blades on the one hand to brace against the fluid to absorb energy and, on the other hand, put energy into the fluid flow without energy expenditure, to energy losses in the rotation against the fluid flow to avoid.

These Task is according to the invention with a Engine for Underwater, river or tidal power plants of the aforementioned Sort of solved.

A Further description of the invention and its advantages will be given below using exemplary embodiments, which are shown in drawing figures.

It demonstrate:

1 the state of the art according to the design idea of Fausto Veranzio in 1595.

2 a section of the engine according to the invention in a perspective view, partially broken away from below.

3 the engine according to the invention in a perspective view, obliquely from above, wherein the blades ( 1 ) according to the fluid flow ( 8th ) worked out.

4 the engine according to the invention in a perspective view, from the side, wherein the blades ( 1 ) according to the 3 worked out.

How out 2 can be seen, the disc ( 6 ) perpendicular to the shaft ( 7 ) indentations ( 3 ) on, in or at which the axes ( 2 ) are mounted. Furthermore, on each blade ( 1 ) a counterweight ( 4 ) or the like.

Each of these blades ( 1 ) settles, through the Counterweights below their axis ( 2 ) balanced, at rest in approximately horizontal position, see 3 - Shovel ( 10 ). The horizontal axes ( 2 ) are - like out 3 visible - preferably completely in the disc ( 6 ) located on the vertical axis / shaft ( 7 ) is attached.

Are the blades due to the fluid flow ( 8th ), the flow only lifts the blades ( 1 ), under which the fluid ( 8th ) can grab. With the then vertical blades ( 1 ) is due to the fluid flow ( 8th ) creates a pressure that the blade ( 1 ) whose horizontal axis ( 2 ) and the vertical axis ( 7 ) turns. Once the pressure of the fluid flow ( 8th ), the blade settles ( 1 ) returns to the horizontal position and rotates flat against the direction of flow, at the moment when the upper edge of the blades ( 1 ) against the flow direction ( 8th ) is directed to straighten up again to reduce the pressure of the fluid flow ( 8th ).

The vertical axis ( 7 ), through the blades ( 1 ), can drive a generator, which is the one of the blades ( 1 ) converted energy into electricity.

So that the blades ( 1 ) remain in the vertical position after erecting and do not fold down due to the fluid flow, the counterweights ( 4 ), which the blades ( 1 immediately after horizontal loss, place them in the vertical position of the blades ( 1 ) by buffer ( 5 ), which when folding up the blades ( 1 ) Absorbs energy in order to bring it back into the horizontal position on the blades ( 1 ) in such a way that the blades, when folded back through the buffer ( 5 ) get supported.

To increase the effectiveness of the engine, the number of blades ( 1 ) are doubled in that the blades ( 1 ) open both up and down ( 3 and 4 ) by adding the same number of blades ( 1 ), which open upwards, z. B. in the section between two upper blades ( 1 ), open at the bottom.

On the blades ( 1 ), the counterweights should preferably be balanced so that all the blades ( 1 ) abut an engine horizontally when no fluid flow ( 8th ) rests against the engine. This ensures that no force has to be applied to the blades ( 1 ) against the flow direction ( 8th ) in a horizontal position. The power needed, the blades ( 1 ) is immediately converted into energy with which the rotation of the engine is generated.

The blades ( 1 ) can be positively controlled in a position that is desired - similar to the rotors of helicopters - so that the engine can also be used as a drive for ships or as a pump. As a marine propulsion two juxtaposed engines that rotate in opposite directions, without causing cavitation, can be used. If the forced control is continuously adjustable, ships can not use a reversing gearbox.

In water areas where the underwater flows against the upper water, the engine can also tilted by 90 ° are used, with the now vertical, but then horizontal axis / wave ( 7 ), to be installed in the water stagnation zone.

The advantages of using an engine for underwater, river or tidal power plants with folding blades ( 1 ) can be seen in the high energy yield in the smallest space. They are environmentally friendly, the energy is renewable, the engine speeds are close to the fluid flow velocity, which z. As a fish death, as avoids the usual turbines, the low price in the production, no or little standstill.

The Engine is as underwater power plant in fast and slow flowing waters can be used, the only small currents exhibit. She works at a current of 1.5 km / h.

she can be used in Europe as a tidal power plant and is not on tidal range or big Instructed depths. It can be considered a floating, anchored power plant or work as a sandbank power plant. It is simple in construction and easy to repair and insensitive to collisions. The Engine can be used for power generation or irrigation also used in developing countries become. She works at high-normal and low-water rivers and also under an ice cover. It is never weather dependent and scoop up there the energy, where this inexhaustible is available.

at Ships can use the engine as an energy-efficient drive What makes even a costly turn gear and a rudder superfluous.

Further The engine can be used as a water pump with high pressure become.
