Construção de um protótipo roda d'água

Abstract

Over the years, along with technological developments, we have seen a growing demand for energy worldwide. This scenario has motivated nations and organizations to seek along with this "evolution", the alternative and conscious use of clean and renewable energy sources. The water wheel is a circular device mounted on a given axis, containing at its periphery arranged tanks, so as to accumulate water in its containers. The water is drawn through a channel and poured into the top of the wheel so as to fill the vats as they pass through the top of the wheel, this causes the vats to increase in weight and mass, causing the rotary movement by means of a difference of gravitational potential energy. The work developed below describes the mechanical functioning of the electric power generating prototype, using a model of the water wheel, which converts the potential energy present in the water into kinetic energy, causing the wheel to spin and consequently the transformation takes place in mechanical energy, this mechanical energy will be responsible for rotating the rotor axis present in the generator. The potential energy present in the water flow is transformed as mentioned above into mechanical energy, this energy (driving force) is transferred by means of an axis which is coupled to the water wheel, the shaft is interconnected in a set of pulleys , these pulleys will make the modification of forces and speeds of the mechanical system, until all movement in the axis of the generator is concentrated.
