Floating microhydrosolar power station

FIELD: electricity.

SUBSTANCE: floating microhydrosolar power station relates to renewable power sources and is intended for supply with the low electric power of residential and non-residential premises, electric and electronic devices, street lighting devices, and also social and field-based facilities located near the flat current rivers, streams, channels, spillways. The power plant uses two renewable energy sources, in particular, water and solar energy simultaneously. The water energy is taken by means of Ugrinsky two-stage turbine with hydrodynamic profile blades. Blades of one stage are turned with reference to another stage by 90° that eliminates unevenness of speed of rotation of this turbine. The water energy conversion directly into electricity is performed by means of the magnetoelectric generator. The solar energy is taken by means of the solar photo-electric modules placed on an external surface of the hemispherical dome located on the hollow cylindrical housing over Ugrinsky armatures. Inside the hemispherical dome the generator is located the shaft of which is connected to an integrated shaft of Ugrinsky armatures.

EFFECT: obtaining an energy efficient integrated solution for power generation from renewable water and solar energy sources.

Known invention hydroelectric patent RU 2451824 C2, F03B 13/10, F03B 7/00 from 27.05.2012 representing a flotation device attached ropes with bearings on the shore containing one row or more turbines, installed in parallel on the hollow platform, turning into sharp edge vertically in the bow. The turbine shafts mounted in bearing supports with the possibility of vertical movement and kinematically connected to an electric generator and starter equipment. On the shafts of the turbines smo�based stars, interconnected chains. Before the flotation device has a filter in the form of a wedge for removal of items. Turbine blades are sickle-shaped profile and is secured to the housings of the shafts so that their edges form with the water a sharp corner. Hollow platforms have in cross section a trapezoidal shape, resulting in sharp edges vertically at the rear of. Upright filter fixedly installed at a distance from a vessel, equipped with rollers allowing rotation. The generator and ballast equipment are installed on the beach. The disadvantage of this invention is the restriction of the use of hydroelectric power on a broad rivers and canals in the Delta of large rivers that does not provide the versatility of its application, and the presence of a chain of gears between the rotors reduces power efficiency. Installation of the generator on the shore requires a complex drive, which should take into account the vibrational displacement boats with installed on their rotors. The method of installation of hydroelectric power does not allow the passage of small vessels and contributes to the collection of other floating objects. Furthermore, the design is bulky and requires costly installation at the jobsite. It is also known invention patent DE 814879 AND, 02.08.2951, F03B 17/06 containing watercraft, sacral�TES ropes with bearings on the shore, turbine with straight blades, a shaft which is mounted in the bearing supports, with the possibility of vertical movement, kinematically associated with the generator, ballast and equipment; hydroelectric contains one row or more turbines mounted on a hollow platforms in parallel, on the shafts of the turbines are mounted sprockets connected by chains, the boats ahead are rigidly fixed lattice in the form of a wedge. The main common drawback of this previous invention is the presence of a chain drive between the rotors, which reduces the efficiency due to the loss of mechanical power transmission and the difference of the speed of rotation of the first rotor and the fourth rotor, located sequentially after the first, second and third rotors. This speed difference occurs due to a power take-off velocity head of water the first rotor, then the second rotor and the third rotor, in this case, the last fourth rotor perceives the velocity head is significantly smaller than the first rotor, chain drive will be to equalize the speed of rotation, therefore, will result in loss of efficiency due to the lower speed of the last (fourth) of the rotor, the speed of which should be raised to the level of the average speed of all rotors is mainly due to the forced reduction soon�STI rotation of the first rotor.
