Description

The Problems of sustainable energy production and reliable supply with electric current not only remains current as before, but special in the face of increasingly scarce natural resources and their increasing demand along with high prices more significant.

The Hydropower has great potential in many regions of the world more natural Energy. However, the use of these energy sources is due to various technical or economic Circumstances difficult or not possible.

To the most productive and economically profitable ways to extract of the electric current hydroelectric power plants of various types and construction methods. Such As a rule, systems have a high degree of utilization. Interesting not only the large and medium-sized devices, which in turn is the largest share in the total electricity production, but also relatively smaller Solutions that at the same time in many cases particularly advantageous and sometimes only possible.

The The following invention is preferably directed to the field of comparative smaller hydropower plants using existing natural resources without big ones Effort and costs without extensive intervention in existing ecosystems benefits. Another area of application is the additional use of the flowing water in the larger facilities: for the Operation of the turbines is certain drop height or water speed required; subsequently could the inventively designed modular hydropower device used because they have the least existing water flow tendency can get along.

advantages

• - the for one optimal operation required total weight of the combined waterwheel can as one of the possible variants be achieved by ballast water, which is a significant reduction the transport weight and the material used
• - the Plant could the power supply in otherwise hard to reach places with the help of existing natural Ensure water sources
• - the Plant can operate largely autonomously: in the rainy seasons It can be put into operation quickly or if necessary be shut down if there is no water

construction

The modular hydroelectric power plant consists of a module WR (combined waterwheel) ( 1 ) or WS (water screw) ( 2 ) with housing 1 , In the case 1 is a combined waterwheel designed according to the invention 2 ( 4 ) or a water snail 5 housed as a drive component and the water supply system with inlet channel 7 and drainage gutter 8th , Also integrated are the generator 3 ( 4 ) and the electronic control 4 , As one of the possible embodiment variant, modular hydropower plant device has a control module ( 3 ). Another component is the tube 9 and 10 as water pipes ( 3 and 4 ) to the entire Vorrich connected.

The housing 1 is preferably made of a weatherproof material (plastic or metal). The texture of the surface and the overall design should make the plant well adaptable to the existing landscape. The front part of the modules WR or WS is preferably with a control window 13 Mistake; This makes it possible to observe or control the processes in the housing from the outside. The housing 1 is constructed in such a way that an extension by further modules ( 3 ) is possible. The connection is preferably done by standardized matched connecting devices.

function

The modular hydropower plant is preferably placed near water sources, so the water the modules WR or WS directly or through water pipe system fed. Due to the working principle of inventively designed combined water wheel, is the height of fall for the degree of utilization of the device not decisive: here is primarily the potential energy (the Weight of water).

If the existing water course has sufficient slope and length, several modular hydroelectric power plants can be installed as batteries. As a result, the existing energy source is used multiple times and via the central control 11 processed and bundled to the consumer.

Combined waterwheel 2 ( 4 )

The Waterwheel consists of several components. The construction of the Rades has at least one component each as an overshot waterwheel (OWR) and as unterschlächtiges Waterwheel (UWR) on, which are firmly connected and so on form a unit. The combined waterwheel may preferably be made of a sturdy, durable plastic and a hollow interior chamber included. This chamber is used for recording from the ballast water to the necessary To gain total weight; For the transport or storage is such a solution in terms of total weight advantageous. For the Operation below freezing point makes the antifreeze mixture useful as ballast water. However, such an embodiment of the combined waterwheel is only one of the possible designs, the expert will be optimal depending on the model and the requirements solution grant.

The water is achieved via the inlet channel 7 above the water wheel in the water wheel cells 12 ( 1 ). By the weight of the absorbed water, the wheel is brought out of balance and can thereby be placed in the rotational movement. The water then falls into the inventively designed gutter, which leads the water to the lower-lying blades of the integrated undershot waterwheel. In this way, the outflowing water supports the rotation of the entire combined water wheel and thus increases the efficiency achieved.

Subsequently, the water is through the drainage channel 8th as well as through the water pipes 9 and 10 out of the module to the outside or to the next module (or 3 ).

Water snail (Archimedean screw) 5 ( 2 )

When Another embodiment of the drive can be a water screw used become. The water snail manages with a relatively low drop height. The module with water screw may be preferred as a supplement to Module can be used with the combined waterwheel by using module with Water snail can be placed lower or completely independent, though the existing fall height for the Operation of the module with water wheel is not sufficient.

The basic principle of the water screw as a device for driving Generators are well known and used in many hydroelectric plants used. New in the present invention is the installation of the water screw in a housing and use as a module.

generator 3 ( 4 )

Around to optimize the overall efficiency of the plant, are the procedures to prefer, if possible direct conversion of the rotary motion into the electric current. Advantageous would be for Example the application of the hub dynamo as a principle, on the one hand reduce the losses of friction and on the other hand the number to keep the individual components or devices so low as it is possible is. in principle the application of other types and types of generators is possible if such an application makes sense from the perspective of a person skilled in the art.

control electronics 4 and control module 11

The installed in the housing electrical control is the necessary conversion and forwarding of the electrical power to the control module or consumer. The control electronics are easily accessible from the outside and, depending on the version, can be placed in different ways troll devices. Inside, the control electronics are waterproof.

The control module 11 collects and processes the electrical energy from the entire modular hydroelectric power plant for further transmission and use.
