Multi-stage power supply power buoy with central pipe

Abstract

The invention discloses a multi-stage power supply power buoy with a central pipe. The multi-stage power supply power buoy with the central pipe comprises a solar cell panel, a lamp holder, a main pontoon and the central pipe; the main pontoon floats on the water surface; the lamp holder is mounted on the top surface of the main pontoon; the solar cell panel can be mounted at the top end of the lamp holder or can be attached to the upper surface of the main pontoon; the central pipe comprises a main straight pipe, a flared pipe and a straight tail pipe which are connected with each other in sequence, wherein the flared pipe is thin at the upper part and thick at the lower part; a through hole is formed in the center of the main pontoon; the main pontoon is arranged on the main straight pipe through the through hole in a sleeving manner; a flange with a mounting hole is arranged at the upper end of the main straight pipe; one or more oscillating water column type wave energy power generation devices can be mounted on the flange; the bottoms of the oscillating water column type wave energy power generation devices communicate with the central pipe; and a storage battery is also mounted on the lamp holder. According to the multi-stage power supply power buoy with the central pipe, multi-stage installed power of a single buoy is realized, problems of long time power supply, inconvenient maintenance and the like of the buoys with different power demands are solved, the working continuity of the buoy is guaranteed, the maintenance cost of the buoy is reduced, and the maintenancesafety of the buoy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of utilization of marine renewable energy, in particular to a buoy capable of realizing multi-level power supply by comprehensively utilizing wave energy and solar power generation. Background technique [0002] Buoys are structures that float on the water surface, and are mostly used for monitoring of marine hydrology, hydrodynamics, meteorology, surface water quality, and navigation aids. The energy sources of buoys are mainly two types: conventional electric energy and renewable electric energy. Conventional power is usually powered by batteries, which need to be replaced regularly; there is also a plan to use shore-based power to supply power to buoys through underwater cables, which requires the laying of underwater cables. The so-called renewable electric energy refers to the use of renewable natural energy to power buoys. Its advantage is that it can generate electricity locally, avoid replacing batt...

Problems solved by technology

Once the power supply of the buoy is determined, the marine instruments it can carry are limited and cannot be flexibly adjusted according to changes in actual needs.
