Abstract

The hydroelectric power plant is installed in the central part of the river in order to make use of the highest river speeed and power as well as the biggest depth. The flow speed is increased bz the flow controllers (8) where, on the lower end, the turbine with blades (5) is installed. Upstream of the turbine, the three-part dam (4) is installed, in particular, the damp part No.1 is placed on the bottom of the flow controlller and the dam parts No.2 and No. 3 are connected over the dam support (3) with the float (6). As the water level rises or lowers, the float moves up and down accordingly raising or lowering the dam parts No. 2 and No. 3 that supply the water to the turbine with blades. The turbines with blades as well as the dams may also be installed at the outlet of the flow controller (8) and thus increase the capacity of the hydroelectric power plant.

Description

HYDROELECTRIC POWER PLANT
DESCRIPTION OF INVENTION
Field of Invention The present invention falls into the Section "H" (electricity) - electric power generation. The subject matter of this invention is a specially designed hydroelectric power plant as per Sub-Section "H02" of the International Patent Classification.
Technical Problem This invention solves the problem of a specially designed hydroelectric power plant that may operate on any river and, by a serial interconnection of several such hydroelectric power plants, a hydroelectric power plant of a desired output is achieved, suitable for various purposes.
State of the Art Hydroelectric power plants currently in operation are relatively low-output and high-cost power plants. They can not operate on any river and require impounding reservoirs for normal operation.
Brief Description of Drawings
This invention is illustrated with the enclosed drawings (Fig. No. 1 and No. 2) showing the structure of the hydroelectric power plant, in particular:
No. 1 corresponds to the dam guide
No. 2 corresponds to the guide slide
No. 3 corresponds to the dam support (float-dam)
No. 4 corresponds to the three-part dam No. 5 corresponds to the turbine with blades
No. 6 corresponds to the float
No. 7 corresponds to the float holder-guide
No. 8 corresponds to the flow controller Brief Structural and Functional Description
The operating principle of the hydroelectric power plant is as follows: The turbine with blades (5) receives the water drive over a three-part dam (4). The dam (4) is a three-part structure in particular: The dam part No. 1 is placed on Hie bottom of the river and its height is adapted to the water level in dry season. The dam part No. 2 is used at medium water level, and the height of the dam part No. 2 is determined at such average water level. The dam part No. 3 is used at high water level and the height of the dam part No. 3 is determined accordingly. The dam part No. 1 may be fixed while the dam parts No. 2 and No 3 are movable and connected to the support (3) that interconnects the dams with the float (6). As the water level rises or lowers, the float (6) moves up and down and over the support (3) raises or lowers the dam parts No. 2 and No. 3. Both the dam part No. 2 and No. 3 have guides on each side with slides incorporated in the wall of the flow controller (8) which enables the upwards or downwards movement of the dams, depending on the river water level.
The turbine with blades (5) is fixed to the lower part of the wall of the flow controller (8) and the float (6) is fixed with two float holders-guides (7) enabling the float to move vertically up and down, depending on the river water level.
The entire hydroelectric power plant is installed in the central part of the river course i.e. the location corresponding to the fastest and deepest section of the river course, thus exploiting the maximum power of the river, even at its minimum water level. The turbine with blades and the above described dam parts may also be installed at the outlet of the water course i.e. river from the flow controller (8) thus increasing the level of the utilisation of the hydroelectric power plant i.e. obtaining of a larger quantity of the electric power (Fig. 2). Besides, the turbines with blades may be smaller - shorter and may be installed horizontally one next to another. All above mentioned turbine installation options will depend on ϋie level of utilisation and technical feasibility at the time of the cost estimate of the hydroelectric plant construction design The hydroelectric plant being the subject of this invention does not need a reservoir for its operation and therefore involves considerably lower construction and operation costs. Such hydroelectric power plants may be constructed very close to each other and serially interconnected to achieve a higher electric power output. In case of high water level, the turbine with blades (5), the dam (4) and the float (6) may be vertically raised to prevent flooding of the neighbouring area. On the flow controllers (8), made of special concrete or some other suitable material, a prefabricated structure is installed, to house the equipment and devices that are necessary for normal operation of the hydroelectric power plant
Application of Invention
The apphcation of this invention features many important advantages, in particular:
1. The use, i.e. installation of several turbines with blades (5) and serial interconnection of several such hydroelectric power plants into a medium or high output hydroelectric power plant.
2. Such a hydroelectric power plant may operate on any river and does not need a reservoir. 3. The hydroelectric power plant operates under any water level conditions, thanks to its three-level dam (4) and float (6). 4. This hydroelectric power plant is installed in the central part of the river course, i.e. the location corresponding to the fastest and deepest section of the river course and, with the aid of the flow controller, enables the exploitation of the maximum power of the river. 5. A prefabricated structure, housing the necessary equipment for the operation of the hydroelectric power plant, is installed on the flow controllers (8). 6. The hydroelectric power plant "Dada" does not need a reservoir, its structure is very simple, and involves very low construction and maintenance costs.

Claims

PATENT CLAIMS
1. The hydroelectric power plant, in respect of the turbine with blades (5), is characterised in that it is installed on the lower part of the flow controller (8) and may be moved by means of the guide (1) and slide (2). The turbine with blades (5) is driven by the water - river flowing over the three-part dam (4).
2. The hydroelectric power plant, in respect of the three-part dam (4) is characterised in that the dam part No. 1 is used under low water level conditions, ύie dam part No. 2 under medium water level conditions and the dam part No. 3 under high water level conditions. The dam part No. 1 is placed on the bottom of the river and the dam parts No. 2 and No. 3 are connected to the float (6) over the support (3). The float (6) raises or lowers the dam parts depending on the water level. The three-part dams (4) and the turbines with blades (5) are installed on the front and back end of the flow controller (8) in order to increase the output of the hydroelectric power plant.
3. The hydroelectric power plant, in respect of the float (6), is characterised in that as the water level goes up and down, the float (6), by means of the float holder (7), rises and lowers accordingly and makes the operation of the hydroelectric power plant possible under any water level conditions, without flooding the neighbouring area.
4. The flow controllers (8) are characterised in that they accelerate the water flow over the dams (4) and increase the number of revolutions of the turbine with blades (5) and thus produce a larger quantity of the electric power. If interconnected in series, several such hydroelectric power plants make one high capacity hydroelectric power plant
5. The hydroelectric power plant is characterised in that a prefabricated structure, housing the necessary equipment for normal hydroelectric plant operation, is mounted on the flow controllers (8).
