Abstract

The invention relates to an installation for converting hydrodynamic energy to mechanical energy and/or for transferring energy using a liquid, especially water, comprising a turbine (2) and a channel (4) that impinges said turbine with a liquid. Said channel, on the inlet side, is impinged by a pump and is a pressure line, and the turbine, on the outlet side, is linked with the inlet of the pump (1) by means of a return line.

Description

Installation for transmission and conversion of energy from water power

The invention relates to a plant for the conversion of hydrodynamic into mechanical energy and / or energy transfer using a liquid, in particular water, with a turbine and a biasing this liquid channel.

Generally known is the principle of the hydroelectric power plant, in which a by a gradient in the corresponding speed, that is, kinetic energy converted water stream strikes a turbine and therein converts the hydrodynamic energy into mechanical rotational energy. In general, the energy is transmitted to a driven-side generator to produce electricity. The dynamic energy of the water is thus converted into mechanical or electrical energy. This requires a sufficient reservoir of water on site with an upstream of the power plant downhill grade by which the amount of water supplied is correspondingly accelerated and charged with kinetic energy. A similar principle is placed in the Radturbinenkraftwerken (millstones) are used, in which the individual blades either in a flowing water immersion (undershot) or in the region of the upper vertex are charged with running water (above schlächtig). In both applications, a substantially constant amount of energy per time is converted irreversibly and in continuous operation. In an intermittent operation permitting drive system, as is known from DE-PS 15 03 276, a with the liquid partially filled reservoir is applied pressure by a gas, so that the output side, the liquid having a correspondingly high speed after application of a liquid turbine flows into a container of low pressure and thereby generating mechanical energy. The acceleration of the liquid is thus antrei- reproduced by exposure to a gas pressure, which is switched on when energy demand. A similar approach disclosed in DE 34 13 617 A1 device in which water is proposed as a means of speeding up the emerging liquid amount works. In this case, the series-connected liquid container are successively acted upon by the pressure medium and the fluid machine supplied.

Proceeding from this, the invention has made the creation of a plant for the task, wherein the drive of the turbine when required and is carried out in an intermittent manner.

This object is achieved according to the invention characterized in that the channel input side, with a pump and a pressure line, and the turbine is on the outlet side via a return line to the inlet of the pump in connection.

In its basic design of the system consists of a liquid-filled channel, and preferably water, which is acted upon on the input side via a pump and the outlet is in communication with a turbine. The distance between pump and turbine is generally desired, so that the proposed system can be used for the transmission of energy. Secondly, there is the possibility the manner of a decoupled transmission convert torques on the pump side in a torque corresponding size on the output side of the turbine. The ratio of the cross section of the pump is determined to which the turbine from the continuity condition of the flowing fluid, the respective ratio of the rotational speeds of the pump and the turbine to one another and therefore also the corresponding torque. The term "pump" in the sense of

a wide interpretation and invention, in addition to himself own ends here primarily axial and radial pumps, all other types of pumps. Likewise, the term includes all turbines liquid turbines - as opposed to steam turbines - in the broadest sense, in which case Schau- felturbinen appear as particularly suitable.

The operation of the system is as follows: By means of the pump, the liquid is set in motion and fed via a channel of the turbine for applying. There in known manner the kinetic energy of the fluid is converted into mechanical rotation energy. These can be used in any desired manner, for example for driving a generator or for application to a vehicle transmission. The outlet side, the liquid is relieved of pressure, such on the turbine. As given below atmospheric pressure. The liquid is led in a closed circuit, that is, the departure side exiting the turbine fluid to the inlet of the turbine returned. One of the key advantages that the circulating fluid is substantially free of gas, ie for. As air inclusions can be maintained which are of Kompressibillität umlaufen- to the liquid-gas mixture and thus cause losses in the

Power transmission means.

It is crucial that the proposed system for the transmission of energy over the defined through the pump and the turbine and medium under stretch excessively large distance but also for the mechanically hydrodynamic conversion of torques eingeset - t may be%. A further advantage is that the entire system will not cause any environmental pollution and in particular, in closed-senem water circuit is completely free of emissions.

As already mentioned with the prior art, the turbine obtained by mechanical energy is often used to drive a generator and thus used to generate electrical energy. Therefore, in an advanta- refinement a generator is driven side to the

Turbine connected. Each energy provided is at least partially to supply the pump as the sole a power supply requiring part of the plant used and provided. Estimates have shown that at such a self-contained, ie independently operating system, a high efficiency is in fact be available 78-85%.

In addition to the kinetic energy generated by the pump, the potential energy can be additionally used, in which a reservoir of liquid in the direction of gravity above the turbine is arranged. The outlet side of the turbine exiting liquid can then sucked by a vacuum in this tank and thus be transported without energy from the outside into the container.

Optimal conditions are present if the and out of the vacuum tank and conveyed by the pump becomes equal takes place in a synchronous manner, that is, the withdrawn in a given time out of the vacuum tank liquid (at the same time the amount of sucked at the outlet of the turbine Flüssigkeitsmen - ge corresponds) is equal to that at this time carried by the pump liquid.

Preferred aim is to cross-link the individual stations of the plant with one another such that the liquid in a closed

Is circulated. The information forwarded by the pump to the turbine fluid is determined by their passage through completely returned to a reservoir which in turn supplies from its side, the pump with fluid. It then creates a self-contained cycle.

If one now provides as a further measure in the case of a closed circuit, that the exchange of the liquid between the adjacent stations in the same amount and time synchronization is performed, which means that the radiation emitted by a station liquid quantity corresponds to that which it receives and temporally these discharge / absorption takes place synchronously, one obtains the result that all the stations always have the same constant amount of water during each phase of operation. So you get a continuous cycle of liquid ness without significant energy must be expended.

At the same time it is ensured that - if present - the acted upon by vacuum or positive pressure gas cushion of a station are maintained for each operating phase.

As already explained above can be carried out by the vacuum in a container, the aspiration of the liquid. Particularly preferred, however, is to provide a gas cushion in a container, on the one adjacent to the liquid and is under pressure. If then the container outlet is opposed to the gas volume substantially, ie that the liquid and not the gas is pressurized in the container outlet, it is achieved that the fluid thus exits the container under appropriate / i pressure and a correspondingly high speed. Depending on the set gas pressure, the acceleration and the velocity of the discharging liquid can be adjusted and varied.

In an expedient development of the use catchy or two-speed metering screw is proposed as pumps. The inlet side fluid is absorbed through the filament of the

Screw accelerated in axial direction in dependence on the speed of the drive axle in the manner of an extruder and discharged coaxially subsequent channel in the. The use of a two-start screw means in accordance with conventional Termologie the application of two staggered spirals on the axis, so that each other are formed on the axis opposite straight line at a section perpendicular to the axis and at equidistance of both spirals as a two-sectional areas. With two spirals, the delivery volume increased significantly in one revolution. The decisive advantage of a dosing screw that it allows to obtain pressure differences between inlet and Ausläse upright. As a rule, the exhaust-side turbine and the leading pressure will be considerably higher than the point let located at the inlet. Another solution that ER- equally transport, while also maintaining a differential pressure laubt is the use of a rotary valve.

is basically conceivable that in the channel between the pump and turbine but may also be included in the inlet-side tank of the pump with the gas cushion. In this way a pressure compensation under different operating conditions of the plant system is effected. On the other hand, have the disadvantage gas cushion within the closed system pump-channel turbine that gas particles are entrained in the liquid bewir- the above-described disadvantages already ken can.

With a correspondingly high power-intensive operation of the plant it comes to heating of the circulating fluid and hence to a change in the self volume. To fen to sheep a balance here can be a buffer suitable construction or use

using cooling the liquid to maintain constant of its own temperature.

In an expedient development of the pump via separate channels te supplies several turbines. It is conceivable an application in which the power supply separate building, takes place with power in such a manner that each building has its own turbine, but these are provided with individual supply line via a common pump station. The turbine serves to drive a generator and the power supply of the building.

Further details, features and advantages of the invention may be taken from the following description, parts in the reference to the

Drawing an embodiment of the invention is explained in detail. Show it:

Figure 1 is a schematic diagram of the system of the invention in side view

The core of the system, the reproduced here as a worm pump pump (1) and thereby charged with liquid turbine (2). They in turn communicates with the generator (3) connected to and over the channel (4) supplied with liquid. At the outlet of the turbine (2) there is a vertical connection to the arranged above the vacuum container (5) which is filled in its lower region with liquid and whose volume about befindliches vacuum is applied.

From there the liquid passes to the pump (1) on the inlet side supplying the intermediate container (6).

The operation is as follows: the pump (1) according to their performance generated a flow of thence via a channel (4) to the turbine (2) passes and drives. This provides the mechanical energy to drive the generator (3) is available, which uses the electricity generated at least partially for driving the pump (1). At the outlet side of the turbine (2) then passes through the remaining kinetic energy or by the

Vacuum in the vacuum container (5) the liquid by way of Ansau- gens on the vertical riser pipe where it passes through a corresponding connection and controlled by a valve in the intermediate container (6) into this region, which in turn (the supply of the pump 1). As a result, we obtain a closed

Circuit for the liquid.

Due to the almost arbitrarily selectable distance between the pump (1) and turbine (2) that is serving with a largely arbitrary length of the supply duct (4) (and also to the loop back connection) is a transfer of energy large, certain only by the friction losses routes possible.
