Ocean buoy utilizing wave energy and solar energy to generate electricity

Abstract

The invention discloses an ocean buoy utilizing wave energy and solar energy to generate electricity, which comprises a shell and a piezoelectric energy harvesting mechanism, a sensor is arranged in the shell, the shell is of a polyhedral structure, a solar panel is laid outside the shell, and two ends of the piezoelectric energy harvesting mechanism are fixed in the shell; the piezoelectric energy harvesting mechanism comprises a support, a plurality of circular ring shells are evenly arranged on the support, the circular ring shells are located in the outer shell through the support, and piezoelectric ceramic pieces are arranged on the circular ring shells. The circular ring shells vibrate and deform on the support under the action of sea waves, and the piezoelectric ceramic pieces are driven to deform to generate electric energy. The solar panel converts solar energy into electric energy to supply power to the sensor. The piezoelectric energy capturing mechanism and the solar panel are arranged at the same time to capture energy of sea waves and solar energy, energy in the nature is fully utilized, the electric quantity is large, and all-day and sustainable power supply is achieved; meanwhile, the structure is easy to miniaturize, the manufacturing cost is low, manual battery replacement is avoided, and the operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of energy collection and micro-power generation, in particular to an ocean buoy using wave energy and solar power to generate electricity. Background technique [0002] Ocean buoys are an indispensable telemetry device for marine meteorological and hydrological observations. It can continuously monitor marine hydrometeorology. Collect data for deep sea scientific research, offshore oil development, port construction and construction. With the gradual expansion of human exploration of the ocean, there is an increasing demand for ocean buoys, and ocean observation requires the use of a large number of buoys. [0003] At present, the power supply methods of marine buoys mainly include battery power supply and solar power supply. Once the battery power supply is exhausted, it cannot be used and the battery needs to be replaced. The power supply can realize the self-power supply of the buoy without replacing t...

Problems solved by technology

[0003] At present, the power supply methods of marine buoys mainly include battery power supply and solar power supply. Once the battery power supply is exhausted, it cannot be used and the battery needs to be replaced. The power supply can realize the self-power supply of the buoy without replacing the battery, but the solar technology is limited by the light intensity, and there will still be insufficient power at night or when the sea is cloudy and the light is insufficient.

The existing power supply technology for marine buoys has high operation and maintenance costs and cannot achieve sustainable power supply for buoys
