-1TURBINA HIDRO-EOLIANA CU PALETE BATANTE-1HYDRO-WIND TURBINE WITH HINGED BLADES

Prezenta invenție se refera la o turbina hidro-eoliana cu palete batante ce poate fi actionata de forța valurilor marine, a cursurilor de apa (râuri, fluvii) sau a vântului, folosind energia potențiala a acestora pentru a produce mișcare circulara in scopul acționarii unui generator electric cuplat la turbina.The present invention relates to a hydro-wind turbine with swing blades that can be driven by the force of sea waves, watercourses (rivers, streams) or wind, using their potential energy to produce circular motion in order to drive a generator. electrically connected to the turbine.

La ora actuala sunt in exploatare cateva tipuri de utilaje sau instalatii in domeniul marin pentru transformarea energiei potențiale in energie cinetica si apoi in mișcare de rotatie, dar complexitatea lor, suplețea execuțiilor respective si randamentul scăzut al acestora, nu a dus la folosirea lor la scara industriala si deci problema este nerezolvata. In domeniul exploatării forței vântului, in prezent se afla mai multe tipuri de turbine eoliene in funcțiune de construcții complexe si randamente diferite, cu costuri de execuție si exploatare ridicate, dar nici un tip cu palete batante.There are currently several types of equipment or installations in the marine field for transforming potential energy into kinetic energy and then rotational motion, but their complexity, the flexibility of their execution and their low efficiency have not led to their use at scale. industrial and therefore the problem is unresolved. In the field of wind power exploitation, there are currently several types of wind turbines depending on complex constructions and different yields, with high execution and operation costs, but no type with swing blades.

Turbina conform invenției isi propune sa rezolve aceste probleme prin aceea ca, pe o construcție metalica de forma cilindrica in lungul careia sunt montate niște palete batante, care in timpul unei rotatii a turbinei, paletele aflate deasupra manetonului (excentricității „e” ) se poziționează radial fata de axul turbinei si deci primesc frontal forța curentului de fluid devenind active, in timp ce paletele aflate in partea opusa manetonului ataca cu muchia (profilul) direcția de deplasare in masa fluidului devenind inactive, dar neopunand rezistenta la înaintare. Astfel momentul de rotatie imprimat paletelor active de forța curentului este efectiv.The turbine according to the invention aims to solve these problems by the fact that, on a cylindrical metal construction along which are mounted some swing blades, which during a rotation of the turbine, the blades above the crank (eccentricity "e") are positioned radially relative to the turbine shaft and therefore receive the force of the fluid current becoming active, while the blades on the opposite side of the crank attack with the edge (profile) the direction of movement in the fluid mass becoming inactive, but not opposing the forward resistance. Thus the torque imprinted on the active blades by the current force is effective.

Cinematica mișcării de poziționare a paletelor, pe durata unei rotatii, se realizează cu ajutorul unui arbore cotit aflat in interiorul turbinei, fixat rigid de postamentul de susținere al acesteia, cu excentricitatea „e” fixata conform indicațiilor din desene (in funcție de modul de exploatare) si a unei perechi de biele pentru fiecare paleta, montate liber cu capul pe manetonul arborelui cotit si cu piciorul pe paleta pe care o rabate funcțional in timpul rotației turbinei. Pentru echilibrul sistemului paletele trebuie sa fie in număr par si minim sase bucăți.The kinematics of the positioning movement of the blades, during a rotation, is made with the help of a crankshaft located inside the turbine, rigidly fixed to its supporting pedestal, with the eccentricity "e" fixed according to the instructions in the drawings (depending on the mode of operation ) and a pair of connecting rods for each vane, freely mounted with the head on the crankshaft crank and the foot on the vane which it folds functionally during the rotation of the turbine. For the balance of the system the pallets must be in even number and at least six pieces.

Turbina este prevăzută cu doua lagare de alunecare la capete si se rotește pe fusurile de la capetele arborelui cotit. Pe unul dintre aceste lagare se montează un angrenaj ( roata de lanț, roata dintata cilindrica sau conica, etc) care poate acționa un generator electric.The turbine is equipped with two sliding bearings at the ends and rotates on the spindles at the ends of the crankshaft. One of these bearings is fitted with a gear (chain wheel, cylindrical or bevel gear, etc.) which can drive an electric generator.

întreaga construcție este executata din profile metalice si deci acțiunea curentilor de apa sau aer nu poate fi distructiva ca asupra unui corp compact.the whole construction is made of metal profiles and therefore the action of water or air currents cannot be as destructive as on a compact body.

- Fig.l, secțiune transversala prin turbina.- Fig. 1, cross section through the turbine.

- Fig.2, secțiune longitudinala prin turbina.- Fig.2, longitudinal section through the turbine.

- Fig.4a si 4b, modele de realizare a bielelor.- Fig.4a and 4b, connecting rod making models.

Turbina confirm invenției este o structura metalica rigida de forma cilindrica, necarcasata, închisa la capete cu doua scuturi (capace) 1 sub forma de grilaj, legate rigid intre ele prin lonjeroanele 2, in axul cilindrului se afla montat un arbore cotit 3, ale cărui capete se fixeaza rigid in postamentul de susținere 4 al ansamblului turbinei, iar pe capetele arborelui cotit 3 se montează liber scuturile 1 care se pot roti pe fusurile acestuia prin intermediul a doua lagare de alunecare.The turbine confirms the invention is a rigid metal structure of cylindrical shape, not cased, closed at the ends with two shields (caps) 1 in the form of a grid, rigidly connected to each other by the side members 2, in the axis of the cylinder is mounted a crankshaft 3, whose the ends are fixed rigidly in the support base 4 of the turbine assembly, and on the ends of the crankshaft 3 the shields 1 are freely mounted, which can be rotated on its spindles by means of a second sliding bearing.

Intre cele doua scuturi 1 se montează paletele 5 cu axele batante 6 si axele de acționare 7 care sunt in număr par si distribuite uniform pe circunferinta cilindrului, iar legătură dintre arborele cotit 3 si axul de acționare 7 al paletei, se realizează prin bielele 8 (doua pentru fiecare paleta) prezentate ca execuție in fig. 4a si 4b, ale căror alezaje se mișca liber pe arborele cotit 3, executând o mișcare de rotatie împreuna cu turbina si o mișcare rectilinie rabatand paleta 5.Between the two shields 1 are mounted the blades 5 with hinged shafts 6 and drive axles 7 which are evenly numbered and evenly distributed on the circumference of the cylinder, and the connection between the crankshaft 3 and the drive shaft 7 of the blade is made by connecting rods 8 ( two for each pallet) shown in Fig. 4a and 4b, whose bores move freely on the crankshaft 3, performing a rotational movement together with the turbine and a rectilinear movement folding the blade 5.

Funcționare; In cazul exploatării in mediul marin, conform fig.3a, in turbina se montează biele tip 4a care datorita excentricității „e” a arborelui cotit 3 si formei alungite a alezajului din capul bielelor 8, paletele 5 pot bascula circa 90 grade împreuna cu axul batant 6. Astfel paletele de deasupra manetonului arborelui ocupa o poziție radiala fata de axul turbinei, expunandu-se curentului apei si devenind active.Operation; In case of exploitation in the marine environment, according to fig. 6. Thus the blades above the shaft crank occupy a radial position with respect to the turbine shaft, exposing themselves to the water current and becoming active.

Când foita curentului fluid pune in mișcare paleta activa, aceasta se va roti tragand după ea biela 8 imprimând întregii structuri un moment de rotatie, aducand in poziție de palete active paletele care in momentul anterior erau inactive. Paletele inactive nu opun rezistenta la înaintare prin masa fluida deoarece ele se deplasează cu muchia (profilul) in direcția de mers a turbinei. Mișcarea de rotatie se transmite angrenajlui 9 care pune in mișcare un generator electric.When the sheet of fluid current moves the active blade, it will rotate by pulling the connecting rod 8, printing a moment of rotation on the whole structure, bringing in position of active blades the blades that were previously inactive. The inactive vanes do not resist the advance through the fluid mass because they move with the edge (profile) in the direction of travel of the turbine. The rotational motion is transmitted to the gear 9 which sets an electric generator in motion.

Daca turbina se montează in mare, fiind supusa acțiunii valurilor, sau complet imersata in apa unui fluviu, montajul se face conform figurii 3a, folosindu-se biele de tip 4a.If the turbine is mounted in the sea, being subjected to the action of waves, or completely immersed in the water of a river, the assembly is done according to figure 3a, using type 4a connecting rods.

In cazul in care turbina se montează in mare, dar in apropiere de tarm, unde curentii de apa sunt activi in ambele sensuri (la partea superioara din larg către tarm, iar la partea inferioara dinspre tarm către larg) atunci montajul seIf the turbine is mounted at sea, but close to the shore, where water currents are active in both directions (at the top from the sea to the shore, and at the bottom from the shore to the sea) then the installation is

Când turbina se montează intr-un curs de apa cu nivel scăzut, dar cu potențial energetic ridicat, atunci montajul se face conform fig.3c folosindu-se biele tip 4a.When the turbine is mounted in a low level watercourse, but with high energy potential, then the assembly is done according to fig.3c using type 4a connecting rods.

Pentru o funcționare mai uniforma si un randament mai bun, in toate cele trei moduri de exploatare (3a, 3b, 3c) se va monta langa turbina o rampa metalica 10 pentru dirijarea fluxului de apa spre zona activa a turbinei.For a more uniform operation and a better efficiency, in all three modes of operation (3a, 3b, 3c) a metal ramp 10 will be installed near the turbine to direct the water flow to the active area of the turbine.

Daca turbina se exploatează eolian, montajul se realizează conform fig.3d, folosindu-se biele tip 4a, turbina va fi prevăzută si cu un ampenaj pentru orientarea arborelui cotit de către vânt in direcția acestuia.If the turbine is operated by wind, the assembly is performed according to fig.3d, using connecting rods type 4a, the turbine will also be provided with a tail for orienting the crankshaft by the wind in its direction.
