Description

"TURBINA EÓLICA VERTICAL PARA ALTO-MAR"■ "VERTICAL SEA WIND TURBINE" ■
Refere-se a presente patente de Invenção a uma turbina eólica de eixo vertical que capta e transforma a força do vento em energia mecânica para geração de eletricidade. Tal turbina gira sobre uma plataforma que flutua em alto-mar. O vento será captado por altas paredes que o afunilam em direção às pás dã turbina. Tais paredes estarão fixas na plataforma que terá formato circular. A plataforma, que estará presa por cabos em um ponto do oceano, se moverá em giro sobre as águas pela ação do vento em conjunto com um motor de propulsão na água. Integra a presente invenção um sistema de flutuação que poderá ser usado para construção de plataformas marinhas para diversas finalidades. Neste invento a turbina e a plataforma flutuam sobre uma camada de ar por sobre as águas. Independentemente do peso da turbina, essa gira suspensa sobre o ar, não havendo pressão sobre rolamentos, sendo significativamente eficiente. Esse é um invento a ser desenvolvido e projetado. Poderá ser de grande ou pequeno porte.  This invention relates to a vertical axis wind turbine that captures and transforms wind power into mechanical energy for electricity generation.

Vivemos em um tempo em que a ciência e a tecnologia buscam a ecologia e a despoluição do planeta. A energia eólica é a mais ecológica, limpa e livre de transtornos ambientais. Atingindo maior grau de eficiência por menor custo, esta estará entre as mais exploradas fontes de energia no mundo. Temos como exemplo o pedido de patente denominado "Turbina eólica flutuante de eixo vertical" do mesmo criador, sendo a invenção que veio a dar origem a esta. A primeira destinada a terra e a presente destinada ao mar, se de grande porte. As atuais turbinas eólicas são pouco eficientes e de elevado custo de manutenção e produção. O que se busca no presente invento é um sistema de grande eficiência e de custo reduzido. Os setores energéticos e industriais são as áreas técnicas as quais se destina a presente invenção. We live in a time when science and technology seek the ecology and the pollution of the planet. Wind energy is the most environmentally friendly, clean and free from environmental disturbances. Achieving greater efficiency at lower cost will be among the most exploited sources of energy in the world. We have for example the patent application called "Vertical axis floating wind turbine" of the same creator, and the invention that gave rise to it. The first intended for land and the present for the sea, if large. Current wind turbines are inefficient and high maintenance and production cost. What is sought in the present invention is a high efficiency and low cost system. The energy and industrial sectors are the technical areas for which the present invention is intended.
Observando em um primeiro exemplo o sistema de captação de vento (fig.1) temos a plataforma redonda com a turbina tipo "Savonious" de seis pás ao centro e duas paredes que afunilam o vento. Essas paredes, que funcionam como grandes defletores, estão posicionadas de forma a conferir enorme rendimento à turbina. Uma se encontra à frente da turbina, em ângulo que pode variar entre 45° e 60° graus (linha pontilhada), canalizando o vento a favor do giro da turbina, que no desenho é anti-horário. Essa primeira parede impede também que o vento colida contra a rotação da turbina. A segunda parede se encontra ao fundo e à direita, tendo mesmo ângulo aproximado de inclinação e com formato curvilíneo ao fundo, sendo que potencializa o rendimento conferindo grande aceleração e força. Testes em túnel de vento certificarão o ângulo de melhor rendimento bem como o afunilamento ideal do vento. Looking at a first example of the wind catchment system (fig.1) we have the round platform with the "Savonious" turbine with six blades in the center and two walls that taper the wind. These walls, which function as large deflectors, are positioned to give the turbine enormous performance. One is in front of the turbine, at an angle that can vary between 45 ° and 60 ° degrees (dotted line), channeling the wind in favor of the rotation of the turbine, which in the drawing is counterclockwise. This first wall also prevents the wind from colliding with the turbine rotation. The second wall is at the bottom and to the right, having the same approximate angle of inclination and with curvilinear shape at the bottom, which enhances performance by giving great acceleration and force. Wind tunnel tests will certify the best performance angle as well as the optimal wind funnel.
Na parte superior do esboço, dois lemes de grande altura que ultrapassam a circunferência da plataforma, manterão toda a plataforma sempre voltada contra o vento. Esses lemes terão altura superior à turbina e atuarão juntamente com um propulsor na água. Como os ventos no mar são constantes, os lemes manterão a posição correta e o uso do propulsor raramente será necessário. Quanto ao sistema de flutuação da plataforma (fig.2), temos uma criação simples e eficiente. Toda a plataforma será construída de concreto. No início do século passado, com a escassez de metal, foram construídos navios de concreto. Porém essa forma de construção foi abandonada pelo fato do metal ter reaparecido em abundância. Nesse invento a plataforma deverá ter formato circular, podendo girar livremente e sem resistência da água. Para isso a superfície em contato com a água deverá ser lisa, tendo reduzida rugosidade. Observando a plataforma em corte lateral (fig.2), vemos sua flutuação sobre o oceano. No centro da plataforma haverá um vão onde será instalado o bojo de flutuação da turbina. Na ampliação (fig.2a) vemos a borda em corte. Tendo esse formato a plataforma flutuará sobre uma camada de ar presa em seu interior. Obviamente todo o concreto deverá ter vedação perfeita contra entrada e saída de ar. O empuxo causado pelo formato da borda, impedirá que ela tombe, mantendo a plataforma presa ao oceano e reduzindo sensivelmente a inclinação e oscilação. Vemos na ampliação (fig.2a) que a borda lateral da plataforma ergue grande quantidade de água acima do nível do oceano pelo empuxo, o que eliminará a oscilação da superfície. A plataforma terá a oscilação do nível de sua profundidade no oceano, que é bem inferior. O ar se encontra preso no interior mantendo a flutuação. Nesse sistema, ao mesmo tempo em que a água empurra o ar que sustenta a plataforma causando a flutuação, a água também puxa a plataforma em toda a sua borda mantendo-a nivelada. O giro ocorrerá facilmente apesar da grande massa de concreto, pois atrito e rugosidade serão mínimos. O formato pontiagudo da lateral tem a função de quebrar as ondas do mar. O triângulo eqtiilátero esboça um vão no concreto que circundará a plataforma e estará cheio de ar, tendo vedação contra entrada de água, minimizando a oscilação e maximizando o equilíbrio. At the top of the sketch, two tall rudders that extend beyond the circumference of the platform will keep the entire platform always upwind. These rudders will be higher than the turbine and will act together with a propeller in the water. Because winds at sea are constant, the rudders will maintain the correct position and propeller use will rarely be necessary. As for the platform fluctuation system (fig.2), we have a simple and efficient creation. The entire platform will be constructed of concrete. At the beginning of the last century, with the scarcity of metal, concrete ships were built. But this form of construction was abandoned because the metal reappeared in abundance. In this invention the platform should be circular in shape and can rotate freely and without water resistance. For this the surface in contact with water should be smooth, having reduced roughness. Looking at the platform in lateral section (fig.2), we see its floating on the ocean. In the center of the platform there will be a gap where the turbine float bowl will be installed. In the magnification (fig.2a) we see the cut edge. Having this shape the platform will float on a layer of air trapped inside. Obviously all concrete must have a perfect seal against air inlet and outlet. The thrust caused by the shape of the edge will prevent it from tipping over, keeping the platform attached to the ocean and significantly reducing tilt and sway. We see from the magnification (fig.2a) that the lateral edge of the platform raises large amounts of water above ocean level by thrust, which will eliminate surface oscillation. The platform will have the fluctuation of its depth level in the ocean, which is much lower. The air is trapped inside maintaining the buoyancy. In this system, while water pushes the air supporting the platform causing the float, the water also pulls the platform across its edge, keeping it level. Spinning will occur easily despite the large mass of concrete as friction and roughness will be minimal. The format Pointed side has the function of breaking the waves of the sea. The equilateral triangle outlines a gap in the concrete that will surround the platform and will be full of air, sealed against water ingress, minimizing sway and maximizing balance.
A construção poderá ser feita em um estaleiro. Após a construção, a plataforma deverá ser inundada. Todo ar existente na borda lateral deverá ser retirado. Um sistema de válvulas manterá a pressão de empuxo da água retirando todo o ar. Em seu interior deverá ser insuflado ar até se atingir a flutuação ideal. Depois será içada até o local em que será fixada. The construction can be done in a shipyard. After construction, the platform should be flooded. All air at the side edge should be removed. A valve system will maintain the buoyant pressure of water by removing all air. Inside, air should be blown until optimal flotation is achieved. It will then be hoisted to the location where it will be fixed.
A plataforma se manterá presa ao centro por um cinturão de trilhos de aço. Esses trilhos de aço formarão o cinturão que circundará o centro da plataforma submerso (fig.2) sendo que o cinturão estará sobre uma grande bóia de aço submersa no oceano. O cinturão, que estará preso à bóia e ao fundo do oceano por cabos, se manterá em um nível constante. A plataforma estará sempre ao nível do mar, de acordo com a maré, que em geral varia cerca de quatro metros. Esse sistema permite que a plataforma se desloque livremente na vertical, através de roletes que predem a trave vertical, subindo e descendo com a maré, mas presa ao centro pelo cinturão de trilhos. Os roletes poderão estar imersos em fluido hidráulico, envoltos por uma capa de borracha sanfonada. Esta descrição é apenas um exemplo, pois o sistema de fixação da plataforma será desenvolvido de acordo com suas dimensões. Quanto ao sistema de flutuação da turbina, este é descrito e assegurado no pedido de patente intitulado "Turbina eólica flutuante de eixo vertical", datado de 15/07/2009, do mesmo criador. A turbina será fixada por dois rolamentos que manterá seu eixo alinhado na posição vertical. Esta turbina flutuará sobre uma camada de ar tendo toda a pressão de sua massa, ali distribuída. Não haverá, assim, pressão sobre rolamentos nem desgaste dos mesmos, sendo o atrito insignificante independentemente de sua massa. Ao fundo do vão da plataforma onde se encontra o bojo que sustenta a turbina, haverá um pequeno orifício que permitirá a entrada de água. Esse vão que se encontra no centro da plataforma, será o reservatório de água onde o bojo de sustentação da turbina flutua e gira. Esse reservatório terá então o mesmo nível do mar, porém como o orifício de entrada de água é reduzido, a oscilação do nível será mínima. Haverá também uma laje de concreto na parte superior do reservatório que terá a função de reduzir ao mínimo o transbordamento de água, impedindo a oscilação vertical da turbina. Esta turbina poderá ser construída com materiais de baixo custo e deverá ser pesada, pois a inércia favorecerá a estabilidade da velocidade de giro em relação à velocidade do vento. O gerador será posicionado acima da turbina ou na plataforma. A massa da plataforma será equilibrada. O empuxo causado pelo sistema de flutuação manterá o equilíbrio. The platform will be held in the center by a steel railing belt. These steel rails will form the belt that will surround the center of the submerged platform (fig.2) and the belt will be on a large steel float submerged in the ocean. The belt, which will be attached to the buoy and the ocean floor by cables, will remain at a constant level. The platform will always be at sea level, according to the tide, which generally varies about four meters. This system allows the platform to move freely vertically through rollers that predict the vertical beam, rising and falling with the tide, but attached to the center by the track belt. The rollers may be immersed in hydraulic fluid, encased in a folding rubber cover. This description is just an example, as the platform fixing system will be developed according to its dimensions. The turbine flotation system is described and secured in the patent application entitled "Floating Wind Turbine". shaft, "dated 15/07/2009, by the same creator. The turbine will be fixed by two bearings that will keep its axis aligned in the vertical position. This turbine will float on a layer of air having all the pressure of its mass there. There will be no pressure on the bearings and no wear on the bearings, and friction is insignificant regardless of their mass. At the bottom of the platform span where the turbine bearing bowl is located, there will be a small hole that will allow water to enter This gap in the center of the platform will be the water reservoir where the turbine bearing bowl floats and rotates.This reservoir will then have the same sea level, but as the water inlet hole is reduced, the oscillation There will also be a concrete slab in the upper part of the reservoir which will have the function of minimizing the overflow of water, preventing the vertical oscillation of the This turbine can be constructed of low cost materials and should be heavy as inertia will favor the stability of the gyration speed relative to the wind speed. The generator will be positioned above the turbine or on the platform. The mass of the platform will be balanced. The buoyancy caused by the flotation system will maintain balance.
Quanto ao presente invento em pequeno porte o mesmo não se destinará ao mar e sim a terra, sendo que não se constituirá dos sistemas de flutuação, mas somente do sistema de captação de vento que consiste de defletores posicionados a frente à esquerda e ao fundo à direita da turbina (fig.1) acelerando o rotor em giro anti- horário. Poderá ser construído em duas modalidades: fixado em cima de uma torre ou no solo. Sobre uma torre os defletores terão livre giro e se manterão sempre contra o vento (fig.3). Um leme ao fundo ultrapassa para cima e para baixo os limites de altura da turbina bem como dos defletores. Leme e defletores formarão uma peça única, movendo-se ao redor da turbina tipo "savonious". Sobre o solo os defletores se moverão sobre um sistema de trilhos ao redor da turbina. Um controle automático, impulsionado por motor elétrico, manterá os defletores sempre contra o vento. As for the present small invention it will not be for the sea but for land, and will not be made up of flotation systems, but only of the wind catchment system consisting of deflectors positioned to the front left and bottom to the rear. right of the turbine (fig.1) accelerating the rotor counterclockwise. It can be built in two ways: fixed in on top of a tower or on the ground. On a tower the deflectors will have free rotation and will always be upwind (fig.3). A rudder at the bottom goes up and down the height limits of the turbine as well as the deflectors. Rudder and deflectors will form a single piece, moving around the savonious turbine. On the ground the deflectors will move on a rail system around the turbine. An automatic control driven by electric motor will keep the deflectors always upwind.
