Abstract

A vertical-axis wind turbine is disclosed, having a large number of movable blades (which rotate only through 1/4 turn around the axes thereof) which, in the vertical direction, are always oriented in the wind direction and, in the horizontal direction, in the opposite direction to the winds. The vertical axis is kept in position by three pillars located at 120° from each other, in a circle with the vertical axis at the centre, and three steel cables in each pillar. Two of the cables start from the ground, 20° away from the pillar, and are attached to the upper end of the pillar. The third cable starts from the ground, together with the pillar, rises to the top thereof, runs over a pulley and on to the support of the upper bearing. Each cable has a tensioner to align and provide the pressure required for the rigidity of the assembly. The turbine can rotate clockwise and anti-clockwise, but once this is determined, it will rotate always in the same sense, whatever the wind direction. Once assembled, the vertical-axis wind turbine looks like a tree.

Description

"TURBINA EÓLICA DE EIXO VERTICAL"  "VERTICAL AXIS WIND TURBINE"
Refere-se o presente invento a uma turbina eólica de eixo vertical com um conjunto de trinta e duas pás distribuídas ao longo do eixo em grupos de quatro, formando assim oito níveis. Os desenhos que acompanham e integram esse relatório mostram: Figura um: vista em perspectiva da turbina com apenas um jogo de pás, os outros são idênticos apenas de um jogo para outro as pás ficam intercaladas para melhor absorção de energia dos ventos. Eixo vertical (1); Pilares de sustentação (2) do eixo vertical; cabo de aço (3) com extensores (4) para alinhar e dar pressão suficiente nos cabos de aço para rigidez do conjunto. Mancai inferior (5) e superior The present invention relates to a vertical axis wind turbine with a set of thirty-two blades distributed along the axis in groups of four, thus forming eight levels. The drawings accompanying and integrating this report show: Figure one: perspective view of the turbine with only one set of blades, the others are identical only from one set to another and the blades are interspersed for better energy absorption from the winds. Vertical axis (1); Support pillars (2) of the vertical axis; wire rope (3) with extenders (4) to align and sufficiently pressure wire rope for rigidity of assembly. Lower bearing (5) and upper
(6) ; Base do eixo vertical (7); Hastes da base (8) dispostas a 120°; Hastes de sustentação (9) do pilar nos extremos das hastes da base(6); Base of the vertical axis (7); Base rods (8) arranged at 120 °; Abutment support rods (9) at the ends of the base rods
(7) ; Base do pilar (11); Roldana (12) do cabo de aço de sustentação do mancai superior; Polia (13) que tem 0 suficiente para multiplicar e transmitir as rotações para o gerador de eletricidade (14) e o local onde será fixada (15) no eixo vertical. Todas as pás (16) têm as mesmas dimensões: comprimento = 6 larguras. Num jogo de quatro pás elas formam duas duplas que estão fixadas num mesmo eixo que cruza o eixo vertical. Os eixos das pás (17) estão fixados nelas a um quarto da largura distante da linha de centro das pás, para formar áreas de impacto (pressão dos ventos) de dimensões diferentes. As faces das duplas de pás (16-A e 16-B) estão deslocadas 90° uma da outra. Os pinos de limitação de giro (20) do eixo das pás permitem que o eixo (17) das pás gire somente um quarto de volta para frente ou para trás. Assim quando uma pá estiver com a face na posição vertical recebendo o impacto e girando com o eixo vertical a favor dos ventos a outra pá está com a face na posição horizontal cortando e girando com o eixo vertical contra os ventos. Desta forma, todas as pás ao longo do eixo vertical, tomando como referencia a linha de direção dos ventos (18), de um lado estão com as faces (16-A) na posição vertical, recebendo o impacto e girando com o eixo vertical a favor dos ventos, e as do outro lado (16-B) estão com as faces na posição horizontal, cortando e girando contra os ventos. A cada meia volta do eixo vertical, quando as duplas de pás se alinharem com a direção dos ventos ocorrem à inversão de posições: pás com as faces na vertical passam para a posição horizontal e vice versa. Essas inversões de posição ocorrem pela ação dos ventos devido às áreas das faces das pás serem de dimensões diferentes pelo fato dos eixos estarem deslocados dos centros das pás e pelos pinos de limitação de giro. A figura 2 - Corte A-A mostra vista frontal do eixo vertical (1 ) onde vemos claramente as posições das pás intercaladas e também com relação à linha de direção dos ventos. As pás "A" pertencem a um nível e estão deslocadas 45° das pás "B" que pertencem ao nível próximo, para melhor distribuição da força dos ventos no eixo vertical. As pás "C" estão com as faces na posição horizontal cortando e girando contra os ventos. As pás "D" estão com as faces na posição vertical recebendo o impacto e girando a favor dos ventos.A figura 2 mostra também o sentido de giro (19); A seta indicando a direção dos ventos (18); Os pinos de limitação de giro (20) do eixo das pás (17) e eixo vertical (1 ). A figura 3 mostra o mancai inferior (5) e superior (1) em cortes, os pinos de limitação de giro (20) das pás e suas fixações nos eixos das pás (17) e no eixo vertical (1 ). O mancai inferior é composto de um suporte (21 ) com tampa (22), uma esfera (23), pino de bloqueio (24) da esfera e dois rolamentos (25). O pino de bloqueio apenas evita que a esfera gire, mas permite um movimento axial de até 5o, evitando dessa forma esforços dos rolamentos quando o eixo vertical sofre envergadura devido ao seu longo comprimento e a pressão dos ventos nas pás. O mancai superior (6) tem o mesmo funcionamento que o mancai inferior, mas sem rolamentos. No desenho vemos o suporte (26) com os ganchos (30) onde serão ficados os cabos de aço (3); Pino de trava (27) da esfera (28) e o eixo (29) de esfera. Os pinos de limitação do giro (20) das pás devem ter um revestimento ou bucha de borracha para evitar ruídos. (7); Abutment base (11); Pulley (12) of upper bearing support wire rope; Pulley (13) which has 0 sufficient to multiply and transmit the rotations to the electricity generator (14) and the location where it will be fixed (15) on the vertical axis. All blades (16) have the same dimensions: length = 6 widths. In a set of four blades they form two pairs that are fixed on the same axis that crosses the vertical axis. The blade axes (17) are fixed thereon to a quarter of the width apart from the blade centerline to form impact areas (wind pressure) of different dimensions. The faces of the paddle pairs (16-A and 16-B) are offset 90 ° from each other. The blade axle swing limit pins (20) allow the blade shaft (17) to rotate only a quarter turn forward or backward. Thus when one blade has its face upright receiving the impact and rotating with the vertical axis in favor of the winds the other blade is with its face in the horizontal position cutting and rotating with the vertical axis against the winds. This way, all the blades along the vertical axis, taking as reference the wind direction line (18), on one side are with the faces (16-A) in the vertical position, receiving the impact and turning with the vertical axis in favor of the winds, and those on the other side (16b) face horizontally, slicing and turning against the winds. Every half turn of the vertical axis, when the pairs of blades align with the direction of the winds occur the reversal of positions: blades with the vertical faces move to the horizontal position and vice versa. These position reversals occur due to the action of the winds due to the areas of the blade faces being of different dimensions because the axes are displaced from the blade centers and by the turning limitation pins. Figure 2 - Section AA shows a front view of the vertical axis (1) where we clearly see the positions of the interleaved blades and also in relation to the wind direction line. Blades "A" belong to one level and 45 ° offset from blades "B" that belong to the near level for better distribution of wind strength on the vertical axis. The blades "C" have their faces in the horizontal position cutting and turning against the winds. The blades "D" have their faces in an upright position receiving the impact and turning in favor of the winds. Figure 2 also shows the direction of rotation (19); The arrow indicating the direction of the winds (18); The swing limit pins (20) of the paddle shaft (17) and vertical shaft (1). Figure 3 shows the lower (5) and upper ( 1 ) sections in cuts, the turning limiting pins (20) of the blades and their fixation on the blades axes (17) and the vertical axis (1). The lower bearing consists of a support (21) with cap (22), a ball (23), ball lock pin (24) and two bearings (25). The locking pin prevents the ball only rotate, but allows an axial movement of the to 5, thereby preventing the bearing effort as the vertical axis scale suffers due to its long length and wind pressure on the blades. The upper bearing (6) has the same operation as the lower bearing, but without bearings. In the drawing we see the bracket (26) with the hooks (30) where will be the steel cables (3); Ball lock pin (27) and ball axis (29). The swing limit pins (20) of the blades should have a rubber plating or bushing to prevent noise.
