Maritime Disaster Prevention and Management gravitational unit

Resumen de: MA66315A1

The technical problem to be solved by the present invention is to overcome the problems caused by tsunamis or exceptional swells. This invention proposes a coastal protection device called a gravity unit for Maritime Disaster Prevention and Management. It consists of a mixed maritime civil engineering structure made of self-healing concrete combined with a metal mechanism designed to protect coastlines from sudden and unpredictable rises in sea level such as medium and low tsunamis, as well as a mechanism for automatically adapting the height of the protective wall to gradual rises in water level.<br />The mechanism also enables desalinated water and/or electricity to be produced using the waves' own energy. Designed to be robust, autonomous and deployable in any location, this mechanism requires no external detection system, no electricity and no intensive maintenance, as it is devoid of electrical circuits known for their mechanical fragility and low tolerance to humidity.<br />In today's world, where global warming is causing sea levels to rise and drought to set in, this device will protect roads and coastal sites, while meeting water and energy needs all along the coast, even in remote areas with no infrastructure.

Power plant to convert wave energy into electricity

Resumen de: MA66481A1

This invention relates to the field of marine renewable energy. It concerns a power plant with a structure that can be built on a coastline, with several reinforced concrete stabilizers, between which several motion sensors are arranged and arranged in a linear fashion. These sensors follow the waves as they rise and fall, sliding on guide rails integrated into the inner faces of the stabilizers. This arrangement allows the trajectory of the motion sensors to be precisely controlled while protecting them from bad weather and other adverse weather conditions. The linear configuration of the motion sensors also allows the energy of the same wave to be captured several times, ensuring optimal, continuous, synergistic operation and a very high capture rate, regardless of weather conditions or wave height. The dimensions of this power plant can be adapted according to the target production capacity and the hydrodynamic conditions of the deployment area.
