Abstract

Apparatus for creating run-of-river power plants (1, 2) which do not require any local changes or interventions and which are capable of utilizing differences in altitude in waters (E1, E2) in terms of energy and thereby automatically the working medium (W) via dams (B) or others To overcome obstacles and to withdraw the positional energy (E1), characterized in that at the top system point a vacuum chamber (D) first the working medium (W) of the upper level (E1) sucks up to this system point, then after overcoming local obstacles over the medium releases a generator (T) to the lower level (U) so as to use the kinetic energy (F) from the potential energy (E1).

Description

The invention relates to a novel device for the use of hydropower potential even lower differences in height (E1, E2), without any technical or structural interventions at the workplace even taking advantage of existing weir or dams (B), as well as natural height differences.

So far, plants that use differences in altitude of water for energy production only stationary plants that are in solid structural connection to the dam and usually work well with low height differences. A simple use of existing potentials is technically and licensing feasible only with great effort and locally fixed.

There are no simple quick and temporary solutions that work effectively with very small height differences.

The invention therefore has the object to solve this problem - in the form of a location-independent device that does not make it necessary to make any interventions or changes locally. This is technically, legally and financially of great advantage.

The device only needs line contact to two different levels of water and can then gain mobile, modular and self-sufficient energy from this. The system is both permanently stationary as well as temporarily only temporarily usable.

The plant overcomes weirs and height differences by similar to the "hydraulic ram" or the "Hieron fountain" here a vacuum helps to suck the water to the necessary height, (Aries presses instead of "pulls" with water hammer and pressure.) To the Barrier to overcome and immediately thereafter by means of the difference in height to the lower body work to make falling, with potential energy is converted here via mechanical energy by means of this fall movement on the generator side into electricity.

Vacuum-assisted run-of-river power plant

Of these, only a small percentage is used again to maintain the negative pressure in the working chamber (D) constant.

While according to the "principle of communicating tubes" this could happen even without negative pressure, the suction force of the vacuum chamber is needed exactly where the power generator interrupts an immediate pressure / suction relationship, ie direct transmission of pressure between intake and downpipe, or physically prevented by using this pressure difference itself.

Therefore, the suction of the falling medium on the suction side (A) must be replaced by the suction of the vacuum chamber (D), which then indirectly by your part of the generator or a control valve (v) is maintained at a vacuum level, so that the necessary initial pressure also maintained in the operating state.

The working pressure of the vacuum chamber can be easily controlled and controlled.

This operating mode in itself means that the generator can run completely constant as long as only the negative pressure in (D) is constantly regulated and it is ensured that there is always sufficient working medium in the suction water storage tank (D).

In contrast to conventional small hydropower plants, this device is a system with much less maintenance and repair by eliminating transmission or any transmission. However, even at different flow rates, measured on the suction side, nevertheless perfectly uniform the optimum speed of the generator is ensured by uniform outflow on the fall side and so the turbine can work with the best possible efficiency.

By using such a controlled turbine, the best possible efficiency is achieved.

Even services that are otherwise normally only produced by means of the more expensive and more expensive Kaplan turbines can thus be achieved by the system.

Device for creating run-of-river power plants ( 1 . 2 ), which require no local changes or interventions and are able to use differences in altitude in waters (E1, E2) energy-technically and thereby automatically lift the working medium (W) over dams (B) or other obstacles and him the positional energy (E1) to withdraw, characterized in that at the top system point a vacuum chamber (D) first the working medium (W) of the upper level (E1) sucks up to this system point, then after overcoming local obstacles, the medium via a generator (T) to the lower level (U) so as to use the kinetic energy (F) from the potential energy (E1). Component according to claim 1, characterized in that at the beginning once by energy input, the negative pressure must be generated, (D), but then the system automatically regenerates the negative pressure during its degradation by lifting power from proportions of energy surplus by the kinetic energy of the total height difference ( E1, E2) or the conversion of the positional energy and mechanical energy into electricity (T). Component according to Claims 1 to 2, characterized in that the device, ( 1 ), which transforms the resulting mechanical energy of the gradient into electrical energy with a water turbine (T) within the system, but this at the top of the system, where the turbine is driven by the pull of the fall side (F), because this suction is too proportional to the continuous regeneration of the vacuum water chamber (D) on the suction side (A) of the upper level (E1) is required. Component according to claim 1 to 3, characterized in that the entire system is designed as a modular system (C) and can be transported well in containers or other containers, the modules (C) can be combined in different ways, and so different types of designs form. Component according to claim 1 to 5, characterized in that the modules (C) can also be used in groups, wherein the use of several basic modules (C), the respective locally necessary power can be provided additively Component according to claim 1 to 6, characterized in that the system inlet ( 2 ) as a suction nozzle (Oe) just below the surface of the upper body of water (O) sucks and so the suction of foreign bodies (flotsam) avoids. Component according to claim 1 to 7, characterized in that the inlet (A) and outlet side (F) of the system also works on distance provided that the nozzles are extended with hoses or pipes, which in turn makes the site of the main unit variable.
