Long-endurance self-energized ocean monitoring buoy

Abstract

The invention discloses a long-endurance self-energized ocean monitoring buoy which comprises a waterproof anti-corrosion sealing shell, a power supply module, a counterweight module and an instrument cabin, wherein the instrument cabin, the power supply module and the counterweight module are sequentially installed in the waterproof anti-corrosion sealing shell from top to bottom; and an energy storage capacitor and electric equipment are arranged in the instrument cabin. Electric energy output of the same phase can be guaranteed only through mechanical fixation, wave energy of an external rectifier bridge is not needed, a friction nano generator is collected, and electric energy output can be effectively increased by increasing the number of the power generation units. The long-endurance self-energized ocean monitoring buoy serves as an energy supply module and is integrated in the buoy carrying the ocean monitoring equipment, the number of the power generation units is increased through parallel integration, electric energy output can be multiplied, and therefore continuous power supply to the ocean monitoring equipment is achieved, and the requirements of current renewable energy source and ocean resource development are met; therefore, a good application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of collection and utilization of wave energy of a friction nanogenerator and ocean monitoring, in particular to a long-endurance self-powered ocean monitoring buoy. Background technique [0002] my country has a vast coastline, ocean wave energy and ocean current energy have a high energy density, and ocean energy is widely distributed. The development and utilization of blue energy has become the top priority to solve the energy crisis. A major difficulty in realizing the construction of smart oceans is that the high complexity of the ocean field makes the energy supply and maintenance of ocean monitoring platforms very difficult. Therefore, using wave energy power generation technology to power ocean sensors attached to buoys is a very feasible technical solution. [0003] The buoy is an effective ocean monitoring platform, which has all-weather and all-day stable and reliable marine environmental data col...

AI Technical Summary

Problems solved by technology

It takes a lot of cost to replace the battery of the buoy in a complex marine environment, and solar power is greatly affected by the weather, so the above power supply forms are not continuous and reliable

[0004] The existing wave energy harvesting friction nanogenerator has the problem of offsetting the phases of the alternating current generated by each unit when multi-units are integrated, and cannot effectively increase the power generation by increasing the number of power generation units to provide the required electrical energy for sensors and other electrical appliances supply; if the method of adding a rectifier bridge is used, it will cause power loss, and at the same time increase the complexity of the connecting circuit and increase the potential failure rate
