Description

The subject of the invention is a device for converting the kinetic energy of a natural watercourse, in particular a river and water accumulated in overflow reservoirs, water of weirs, streams or dams, into mechanical energy and its conversion into electricity, sent to an external electrical network and / or to batteries. Bearing in mind climate and environmental change, the European Commission sets clear and unambiguous goals to minimize greenhouse gas emissions in the coming decades by obtaining renewable energy from every possible area on the continent. Rivers represent a significant potential source of renewable energy, with some rivers remaining untapped due to their small size, requiring the construction of costly dams capable of generating electricity that can be used both directly to drive machinery and to store it in batteries. There are many solutions where the water flowing in the river drives a water turbine or a water wheel. The commonly known hydropower plants allow for the generation of electricity by converting the kinetic energy flowing in the river water into mechanical energy in a turbine, and then through a generator connected to it into electricity, and the energy thus produced is classified as renewable energy. The basic element of a hydroelectric power plant is a water turbine made of a metal rotor equipped with blades, which rotates under the influence of the flowing water and converts the kinetic energy of water into mechanical energy, which in turn is used to produce electricity by means of a generator coupled with the turbine. The rotating turbine rotor rotates the generator shaft through the gear system and generates electricity, which is then sent to the power grid. The commonly known Kaplan water turbines are characterized in particular by the fact that a rotor equipped with blades and a generator set, as well as other elements of the turbine set are mounted on the vertical main shaft. In these turbines, the vertical main shaft bearing consists of the lower radial bearing and the upper longitudinal-transverse bearing. During the operation of this turbine, two forces act on the main shaft with directions perpendicular to each other, the size of which changes during various operating conditions. An energy device that uses the water of a mountain river to generate electricity, without building a dam known from the Polish patent application no. P343661, has a power pipe with a front water filter immersed in the water through a built artificial water threshold, which is mounted to the bottom of the river, connected to the lower end of the pipe is an open main valve connected to a power collector with a diameter increased by at least 100% of that pipe, which is also connected to a water turbine connected to a power collector equipped with a blade water turbine connected to a power generator. The blade water turbine is also connected to a pipe leading the water back to the river bed, while the lower end of the power pipe with an energy valve embedded in it is led to the outside building. The Polish patent description PL207540B1 describes a hydropower plant for generating electricity by converting the energy of the water flow by means of a flowing machine with at least one rotor, a rotor-driven generator and a float for a permanently anchored flow-through machine, and the rotor is oriented in the direction of flow, while the machine is kept floating below the surface of the water by feeding the float with a gaseous medium, for example compressed air, and possibly flooding it, and the rotor is mounted on an axis oriented in the direction of the water flow. This power plant is characterized in that the blades of its rotor are adjustable in the direction of flow and / or in the opposite direction by means of a regulating mechanism, the axis of the rotor has the form of a hollow axis and is a float, while the blades of a non-rotating rotor are pivotable in the direction of flow and directed against the hydrodynamic thrust by means of a spring. Also from the Polish patent description PL 168422 a small hydroelectric power plant with a turbine-generator located on the upper water side is known, characterized in that the power plant block is located on the bottom spouts on the upper water side, and the turbo-generator of this power plant block is mounted by means of a conical suction pipe on an elbow-pipe connector fastened to a grate placed in the recess of the maintenance closure of the bottom outlet, the turbo-generator of this small power plant is covered with a lattice chamber enclosure connected to the turbine seat. The block of this hydroelectric power plant forms an adit draining water from the turbine-generator to the bottom outlet located at one end in the recesses of the maintenance closure. The Polish patent description PL223636 also describes a device for generating electricity from hydropower, especially for low water drops and weirs or dams, consisting of a trough located in the weir with gate valves, and a system of arms is mounted in the trough, inclined with at least one rotor water turbine, preferably with a brake, connected to the generator, characterized by the fact that the weir has an adjustable upper damper and an adjustable lower damper, and the trough attached to the weir is equipped with steel beams attached to the bottom of this trough, on which the stabilizing blocks are placed, and the water turbine is a water wheel, placed transversely to the direction of water flow, on the system of tilting arms enabling the lifting and moving of this wheel, together with the system of transferring the rotation of the generator gearbox up and back. In turn, a stationary water power plant, known from the Polish patent description PL220459, having a turbine with a horizontal axis of rotation and tubular blades placed on the outer radius of the rotor used to generate electricity by converting the forward motion energy of a watercourse, for example a river, into the rotor shaft torque of this power plant, it has a functional system (converting, converting the energy of the watercourse) with other elements such as: hub, gear, generator, tower and servomechanisms - a water power plant for generating electricity, where this functional system at the input has a rotor with a hub and tubular shovels connected to the highspeed shaft of the electric generator through a gearbox.

On the other hand, in the event of a decrease in the water level in the river 6, for example in the event of an atmospheric drought, the signal transmitted by the non-contact sensor 45', the controller installed in the electric box 76 automatically activates the driving subassembly 53 of the pusher 17 connected to the support frame 1, causing the displacement of this frame to the maximum extent possible up to 85° in relation to the reinforced concrete foundation 4, i.e. in the direction of the gravitational flow of water and the water stream advancing it on the blades 36 of the vertical water turbine 10, until the required water level is reached (damming up in the bed of this river), advancing against the sheet metal barrier 24 of the support frame 1, allowing the normal rotation of the blades 36 of this water turbine 10 and the continuation of converting the kinetic energy of the river water stream into mechanical energy and converting it into electricity and transmitting it via an electric conductor 51 from the electricity generator 50 to the external electricity grid or batteries.
