Hydroscrew

The hydroscrew is a turbine operated by the weight of water, acting as a gravimetric machine. The water fills the compartments of the screw, which descend due to their own weight and the helical surface of the propeller, generating the rotation of the screw and converting potential energy into mechanical energy.

It consists of a turbine where the water allows the system to operate mainly by its own weight, thus considered a gravimetric machine; the water fills the cavities of the screw that function as drawers that move downwards due to the action of its weight and the helical surface of the propeller surface, makes the screw turn, in this way the potential energy is transformed into mechanical energy and finally the electric energy is obtained through the use of a generator coupled directly or indirectly to the screw shaft. The use for the generation of electric energy is recent, the application of the screw is presented as an important alternative to take advantage of water resources on a small scale and mini hydroelectric plants, and in water resources such as small rivers or irrigation canals with smaller waterfalls. Also, the hydroscrew can be applied from a principle inverse to that of electric energy generation, that is, it can be used as a water transporter and dispenser (pump), applying electric energy.
