Abstract

The invention discloses a self-propelled wave energy and tidal current energy comprehensive utilization platform and method, and relates to the technical field of wave energy conversion. The self-propelled wave energy and tidal current energy comprehensive utilization platform comprises two sheet bodies which are oppositely arranged in parallel, a deck bridge, a pneumatic type wave energy power generation device and a horizontal shaft ocean current energy power generation device. Each sheet body comprises a horizontal pipe parallel to the horizontal plane and a vertical pipe perpendicular to the horizontal plane, and the horizontal pipe and the vertical pipe are connected and separated through the gate; the deck bridge is arranged between the two sheet bodies and used for connecting the two sheet bodies, and the deck bridge is further provided with a lifting mechanism; the pneumatic type wave energy power generation device comprises an air chamber at least partially serving as the vertical pipe, the cross section area of the upper portion of the air chamber is gradually reduced to form the air hole, and an air turbine and a first power generator which are in transmission with each other are installed on the air hole; and the horizontal shaft ocean current energy power generation device comprises a second power generator installed at the lower end of the lifting mechanism and a horizontal shaft impeller installed on an input shaft of the second power generator.

Description

technical field [0001] The invention relates to the technical field of wave energy conversion, in particular to a platform and method for comprehensive utilization of self-propelled wave energy and tidal current energy. Background technique [0002] Among the many renewable natural resources, marine renewable energy has many advantages such as clean and green, sustainable utilization, and great development potential. Many countries in the world regard it as a strategic resource for technical reserves. Ocean energy includes tidal energy, wave energy, tidal (sea) current energy, temperature difference energy, and salinity difference energy. Tidal (sea) current energy refers to the kinetic energy of seawater flow, mainly refers to the energy generated by the regular seawater flow caused by tides and the relatively stable flow in submarine waterways and straits. Wave energy is transmitted to the ocean by wind And produced, it is essentially formed by absorbing wind energy. Wav...

Problems solved by technology

[0004] 1. The multi-energy power generation system with fixed pile foundation cannot be moved. In order to resist the damage of harsh sea conditions, the structural design has to be strengthened, which virtually increases the construction cost of the system, and cannot guarantee the safety under typhoons;

[0005] 2. Most of the floating multi-energy power generation systems adopt the form of multi-floats (one main body with multiple floats). The joints between the floats and the floats may be deformed and dangerous under severe sea conditions, and the safety is not high, and the tide ( The efficiency of the sea current energy and wave energy power generation system is greatly affected by the main body (some tidal (sea) current energy and wave energy power generation systems are directly attached to the main body, and the propagation direction of waves and currents is greatly affected by the main body, so power generation The power generation efficiency of the system is more affected by the main body)
