Description

SISTEMA DE REAPROVEITAMENTO DA ENERGIA MECÂNICA DE ESCADAS ROLANTES E CONGÊNERES PARA MICROGERAÇÃO DE ENERGIA ELÉTRICA SYSTEM FOR REUSE OF MECHANICAL ENERGY FOR ENCLOSURES AND CONGENERATIONS FOR MICROGENERATION OF ELECTRIC ENERGY
INTRODUÇÃO INTRODUCTION
[0001] Refere-se o presente pedido de patente de invenção de um inédito “SISTEMA DE REAPROVEITAMENTO DA ENERGIA MECÂNICA DE ESCADAS ROLANTES E CONGÊNERES PARA MICROGERAÇÃO DE ENERGIA ELÉTRICA” - trata de um sistema que utiliza o excedente, total ou parcial, da força mecânica do motor elétrico que alimenta todo o mecanismo móvel de uma escada rolante, ou congênere, para transforma-la em energia elétrica, pela conexão de um gerador eólico de velocidade fixa a tomada de força de força na referida escada rolante, preferencialmente, mas não necessariamente o eixo do motor elétrico por meio de acoplamentos mecânicos, polias e correias ou engrenagens. [0001] Refers to the present patent application for the invention of an unprecedented "SYSTEM FOR REUSE OF MECHANICAL ENERGY OF ENCLOSURES AND CONGENERATIONS FOR MICROGENERATION OF ELECTRIC ENERGY" - it deals with a system that uses the total or partial surplus of mechanics of the electric motor that feeds the entire moving mechanism of an escalator, or the like, to transform it into electrical energy, by connecting a fixed speed wind generator to the power take-off on said escalator, preferably, but not necessarily the electric motor shaft by means of mechanical couplings, pulleys and belts or gears.
CAMPO DE APLICAÇÃO APPLICATION FIELD
[0002] O campo de aplicação da invenção é o segmento de reaproveitamento de energia com a utilização de escadas e esteiras rolantes, os quais são equipamentos, que apresentam alto grau de carregamento, utilizados no transporte de pessoas ou cargas a curtas distâncias. [0002] The field of application of the invention is the energy reuse segment with the use of escalators and moving walks, which are equipment, which have a high degree of loading, used to transport people or loads over short distances.
[0003] As escadas rolantes (com inclinação de 30s a 35s) são muito utilizadas em shoppings centers, lojas de departamentos, hipermercados etc., ao passo que as esteiras rolantes, horizontais, são normalmente empregadas em locais com grandes corredores, como, por exemplo, aeroportos e hipermercados. [0003] Escalators (with an incline of 30 s to 35 s ) are widely used in shopping malls, department stores, hypermarkets, etc., while horizontal moving walks are usually used in places with large aisles, such as , for example, airports and hypermarkets.
CONVENCIMENTO CONVICTION
[0004] O conceito e o mecanismo de funcionamento de uma escada e de uma esteira rolante são muito parecidos. Geralmente, as do tipo comercial, utilizam um motor elétrico de 100 hp para acionar todo o mecanismo móvel do equipamento, que, basicamente, consiste de um par de correntes ligando todos os degraus, a qual circula entre engrenagens de tração e engrenagens de retorno, além do mecanismo do acionamento dos corrimãos, estes com velocidade sincronizada com a escada. [0004] The concept and working mechanism of a ladder and a moving walk are very similar. Generally, the commercial type, use a 100 hp electric motor to drive the entire moving mechanism of the equipment, which basically consists of a pair of chains connecting all the steps, which circulates between traction gears and return gears, in addition to the handrails drive mechanism, these with speed synchronized with the stairs.
[0005] Via de regra, o motor supracitado é dimensionado para entregar uma força até 30% superior à que é exigida para o funcionamento normal do equipamento, com a carga máxima, como se fosse uma reserva energética. Entretanto, essa força mecânica excedente disponibilizada pelo motor elétrico, além de consumir energia, é totalmente desperdiçada e sem nenhum aproveitamento. [0006] Um aerogerador ou um sistema de geração de energia eólica é constituído, em regra, pela torre metálica, nacele, rotor, gerador elétrico e pás, leme, sistema de yaw (orienta a direção em que a nacele deve permanecer apontada com relação ao vento, sistema de frenagem para casos de emergência, sistema de arrefecimento e sistema de pitch (encarregado de controlar o ângulo de ataque das pás). Os geradores elétricos utilizados nos aerogeradores são de grande eficiência, pois utilizam potentes ímãs de neodímio, que geram quantidades significativas de energia elétrica, embora essa geração dependa totalmente do regime dos ventos, sua constância, sua força, sua velocidade e outros fatores atmosféricos que limitam significativamente a geração de energia elétrica. [0005] As a rule, the aforementioned motor is dimensioned to deliver a force up to 30% higher than that required for the normal operation of the equipment, with maximum load, as if it were an energy reserve. However, this excess mechanical force made available by the electric motor, in addition to consuming energy, is totally wasted and without any use. [0006] A wind turbine or a wind power generation system is constituted, as a rule, by the metallic tower, nacelle, rotor, electric generator and blades, rudder, yaw system (orients the direction in which the nacelle must remain pointed with respect to to the wind, a braking system for emergencies, a cooling system and a pitch system (in charge of controlling the angle of attack of the blades). significant amounts of electrical energy, although this generation totally depends on the wind regime, its constancy, strength, speed and other atmospheric factors that significantly limit the generation of electrical energy.
ESTADO DA TÉCNICA STATUS OF THE TECHNIQUE
[0007] O atual estado da técnica antecipa alguns documentos de patentes com novas tecnologias que versam sobre reaproveitamento de energia em escadas rolantes, como o BR 102016028632-8 intitulado “SISTEMA DE GERAÇÃO DE ENERGIA EM ELEVADORES E ESCADAS ROLANTES” - configura um sistema que emprega geradores de energia específicos, que convertem a energia mecânica gerada na movimentação de elevadores e escadas rolantes, e acumula essas energias em baterias (Off Grid) ou injeta diretamente na rede elétrica para a geração de créditos (Grid Tie). O aproveitamento de energia se dá pela aplicação de blocos de imãs permanentes nas paredes fixas com lâminas estatoras e bobinas de cobre ou alumínio, não importando a forma que se adaptarão nos elevadores ou escadas rolantes. [0007] The current state of the art anticipates some patent documents with new technologies that deal with energy reuse in escalators, such as BR 102016028632-8 entitled "ENERGY GENERATION SYSTEM IN ELEVATORS AND Escalators" - configures a system that employs specific energy generators, which convert the mechanical energy generated in the movement of elevators and escalators, and accumulate this energy in batteries (Off Grid) or directly inject it into the electrical grid to generate credits (Grid Tie). Energy is used by applying permanent magnet blocks to the fixed walls with stator blades and copper or aluminum coils, regardless of the way they are used in elevators or escalators.
[0008] O documento de anterioridade acima utiliza um princípio de reaproveitamento de energia que utiliza o próprio peso do sistema como alavanca de peso e não a força mecânica no eixo do motor elétrico ou dos outros pontos móveis da escada rolante. [0008] The previous document above uses a principle of energy reuse that uses the system's own weight as a weight lever and not the mechanical force on the electric motor shaft or other moving points of the escalator.

DESCRIÇÃO DETALHADA DA INVENÇÃO DETAILED DESCRIPTION OF THE INVENTION
[0018] “SISTEMA DE REAPROVEITAMENTO DA ENERGIA MECÂNICA DE ESCADAS ROLANTES E CONGÊNERES PARA MICROGERAÇÃO DE ENERGIA ELÉTRICA”, objeto desta solicitação de patente de invenção trata de um sistema que utiliza um gerador eólico de velocidade fixa (3), de forma alinhada, com o motor elétrico (1 ), ou outras tomadas de força, de escadas (2) rolantes e congêneres, com o objetivo de aproveitar a sua força excedente e transforma-la em energia elétrica para aproveitamento no próprio estabelecimento onde o equipamento está instalado ou distribuir para a rede pública (15), em caso de sobra, pelo sistema on grid. [0018] "SYSTEM FOR REUSE OF MECHANICAL ENERGY OF ENCLOSURES AND CONGENERATIONS FOR MICROGENERATION OF ELECTRIC ENERGY", object of this invention patent application deals with a system that uses a fixed speed wind generator (3), in an aligned manner, with the electric motor (1), or other power take-offs, of escalators (2) and the like, in order to take advantage of their surplus power and transform it into electrical energy for use in the establishment where the equipment is installed or to distribute to the public network (15), in case of surplus, by the on grid system.
[0019] Mais particularmente, a invenção reivindica um sistema que utiliza, de forma simultânea, um motor elétrico (1 ) que aciona uma escada (2) ou esteira rolante (não demonstrada) e um gerador eólico de velocidade fixa (3), conectados por meio de um acoplamento (4) mecânico comum que une, de forma alinhada, o eixo (5) do motor elétrico (1 ) com o eixo (6) do rotor (não demonstrado) do gerador eólico de velocidade fixa (3). O acoplamento (4) mecânico, disponibilizado no mercado, pode ser de aço, material flexível ou qualquer outro conhecido. Desse modo, o gerador eólico de velocidade fixa (3) sempre conectado ao motor elétrico (1 ) cuja força mecânica excedente irá gerar energia elétrica continuamente pode ser direcionada na rede do próprio estabelecimento, onde se encontra a escada (2) ou esteira rolante (não demonstrada) pelo sistema on grid. Conforme o número de rotações do motor elétrico (1 ) e do gerador eólico de velocidade fixa (3), mais especificamente se as rotações forem diferentes o acoplamento (4) mecânico poder ser substituído por outros acoplamentos como polias (7, 7’) e correias (8). Em uma forma de viabilização da invenção, se um motor elétrico (1 ) trabalhar com 1.200 rpm e o gerador eólico de velocidade fixa (3) trabalhar com 300 rpm, haverá necessidade de se utilizar pelo menos duas polias (7, 7’) e uma correia (8) para reduzir as rpm do motor elétrico (1 ) para as 300 rpm que o gerador eólico de velocidade fixa (3) necessita. Nesse caso, utiliza-se uma polia (7) de 200 mm de diâmetro no eixo (5) do motor elétrico (1 ), polia motora, e uma polia (7’) de 800 mm de diâmetro no o eixo (6) do rotor do gerador eólico de velocidade fixa (3), polia impulsionada ou movida, interligadas por uma (ou mais) correias (8), de modo que o gerador eólico de velocidade fixa (3) receberá exatamente as 300 rpm que necessita para o seu funcionamento normal, configurando assim um redutor de velocidade para transformar uma velocidade mais alta (1.200 rpm) em uma velocidade mais baixa (300 rpm) sem que haja alteração na rotação do motor elétrico (1 ) da escada (2) rolante ou congênere. Dependendo da necessidade poderão ser utilizadas duas ou mais correias (8), que serão movidas simultaneamente, com a mesma velocidade, através de polia dupla, tripla, quádrupla, etc. O mesmo artificio poderá ser viabilizado por engrenagens (9). Além do eixo (5) do motor elétrico (1 ), o eixo (6) do rotor do gerador eólico de velocidade fixa (3) poderá ser conectado a outras tomadas de força da escada (2) rolante ou congênere como na engrenagem de tração (10), no acionamento do corrimão (11 ) e na engrenagem de retorno (12), quer seja por meio de acoplamentos (4) mecânicos, polias (7) e correias (8) e engrenagens (9). O sistema on grid é utilizado porque o gerador eólico de velocidade fixa (3) que é ligado ao motor elétrico (1 ), ou outra tomada de força, da escada (2) rolante ou congênere para produzir energia em corrente contínua, que para utilização no local/ estabelecimento necessita ser transformada em corrente alternada (AC). Para tanto essa corrente CC passa por um controlador (13) e daí segue para um inversor (14) que a transforma em corrente alternada (AC) 127v ou 220v, injetando-a na rede do próprio estabelecimento. Se o consumo local for maior do que o gerador eólico de velocidade fixa (3), o estabelecimento consome a energia produzida e retira o restante da rede pública (15). Se a produção do gerador eólico de velocidade fixa (3) for maior do que o consumo local, o excedente entra na rede pública (15) e o medidor de energia (16) bidirecional registra a quantidade de energia elétrica injetada na rede para posterior compensação. [0019] More particularly, the invention claims a system that uses, simultaneously, an electric motor (1) that drives a ladder (2) or moving walk (not shown) and a fixed speed wind generator (3), connected by means of a common mechanical coupling (4) that aligns, in an aligned manner, the axis (5) of the electric motor (1) with the axis (6) of the rotor (not shown) of the fixed speed wind generator (3). The mechanical coupling (4), available on the market, can be made of steel, flexible material or any other known material. In this way, the fixed speed wind generator (3) always connected to the electric motor (1) whose excess mechanical force will continuously generate electrical energy can be directed into the network of the establishment itself, where the ladder (2) or moving walk ( not shown) by the on grid system. Depending on the speed of the electric motor (1 ) and the wind speed generator fixed (3), more specifically if the rotations are different, the mechanical coupling (4) can be replaced by other couplings such as pulleys (7, 7') and belts (8). In a way of making the invention feasible, if an electric motor (1) works at 1,200 rpm and the fixed speed wind generator (3) works at 300 rpm, it will be necessary to use at least two pulleys (7, 7') and a belt (8) to reduce the rpm of the electric motor (1) to the 300 rpm that the fixed speed wind generator (3) needs. In this case, use a pulley (7) with a diameter of 200 mm on the shaft (5) of the electric motor (1), motor pulley, and a pulley (7') with a diameter of 800 mm on the shaft (6) of the fixed speed wind generator rotor (3), driven or driven pulley, interconnected by one (or more) belts (8), so that the fixed speed wind generator (3) will receive exactly the 300 rpm it needs for its normal operation, thus configuring a speed reducer to transform a higher speed (1,200 rpm) into a lower speed (300 rpm) without changing the rotation of the electric motor (1) of the escalator (2) or the like. Depending on the need, two or more belts (8) can be used, which will be moved simultaneously, with the same speed, through a double, triple, quadruple pulley, etc. The same artifice can be made possible by gears (9). In addition to the shaft (5) of the electric motor (1 ), the shaft (6) of the fixed speed wind generator rotor (3) can be connected to other power take-offs of the escalator (2) or the like as in the traction gear (10), in the handrail drive (11) and in the return gear (12), either by means of mechanical couplings (4), pulleys (7) and belts (8) and gears (9). The on grid system is used because the fixed speed wind generator (3) is connected to the electric motor (1), or another power take-off, of the escalator (2) or the like to produce direct current energy, which for use on site/establishment needs to be transformed into alternating current (AC). For this purpose, this DC current passes through a controller (13) and then goes to an inverter (14) that transforms it into alternating current (AC) 127v or 220v, injecting it into the establishment's network. If the local consumption is greater than the fixed speed wind generator (3), the establishment consumes the energy produced and withdraws the rest from the public grid (15). If the production of the fixed speed wind generator (3) is greater than the local consumption, the surplus enters the public grid (15) and the bidirectional energy meter (16) records the amount of electric energy injected into the grid for later compensation .
