Technical Field

The invention relates to the technical field of power generation equipment, in particular to a wave energy power generation device.

Background

The wave energy reserves are huge, the distribution is wide, and the wave energy reserves are clean renewable energy with development prospect. Wave energy converters are generally classified into Oscillating Water Column (OWC) devices, Oscillating Body (OB) devices and overtopping devices according to their operating principle. Among these devices, OWC is considered one of the most feasible options.

In view of the high costs of OWC installation and maintenance, it is an effective way to reduce the budget to combine it with other offshore structures such as breakwaters. Indeed, in addition to cost sharing, the integrated system may also significantly improve power extraction, particularly for coastal/breakwater integration with OWCs. Cylindrical OWCs that are semi-embedded on straight coasts have about twice the extraction efficiency of an isolated OWC due to coastal reflections.

In practical application, the wide-bandwidth and high-efficiency OWC can generate stable power for various ocean waves. However, conventional single-chamber OWCs can only perform well over a fairly narrow frequency range around the resonant frequency.

The invention aims to solve the technical problem of providing an embedded double-chamber oscillating water column wave energy device capable of extracting waves with different frequencies and further providing an embedded double-chamber oscillating water column wave energy device mounting structure.

The technical scheme adopted by the invention for solving the technical problems is as follows: an embedded double-chamber oscillating water column wave energy device comprises a first air chamber and a second air chamber, wherein the first air chamber is barrel-shaped, the second air chamber is tubular, and the inner diameter of the first air chamber is larger than the outer diameter of the second air chamber;

the open end of the first air chamber is a first water inlet, and the second water inlet is positioned on the side wall of the second air chamber;

the first air outlet is communicated with the first air chamber, and the second air outlet is communicated with the second air chamber;

the second air chamber is positioned in the first air chamber and coaxially arranged with the first air chamber, the first water inlet is positioned above the second water inlet, and the second air outlet penetrates through the first air chamber.

Further, the axis of the first air outlet is perpendicular to the axis of the first air chamber.

Further, the second air outlet penetrates through the bottom plate of the first air chamber.

Further, the second air outlet is arranged coaxially with the second air chamber.

Further, a fluorescent layer is arranged on the outer wall of the first air chamber.

Embedded two room oscillating water column wave energy device mounting structure, including the bank line, still include aforementioned embedded two room oscillating water column wave energy device, the outer wall embedding of first air chamber is fixed in the bank line, and first water inlet and second water inlet all communicate with the waters.

Further, the first air outlet is arranged back to the water area.

Further, the second water inlet is arranged back to the shore line direction.

The invention has the beneficial effects that: the double-chamber structure can change the characteristic length of the first air chamber and the second air chamber by changing the inner diameter of the first air chamber and the outer diameter of the second air chamber, and wave energy with different wavelengths can be converged into the OWC by changing the characteristic length. The wave's wavelength is frequency dependent, and by collecting wave energy at different wavelengths, the frequency range over which the wave energy is absorbed can be varied. In practical application, the ratio of the inner diameter of the first air chamber to the outer diameter of the second air chamber can be changed according to the frequency of the spectral peak of the actual sea area, so that the wave frequency of the actual sea area can be better matched, waves with different frequencies can be extracted, and the efficiency of wave energy power generation can be maximized.

According to the invention, the wave energy device is coupled with the breakwater or the shoreline, the OWC is embedded into the breakwater or the shoreline, and the wave can contact with the OWC device firstly, so that a part of wave energy can be absorbed firstly, thus the wave energy absorbed by the shoreline or the breakwater is reduced, the shock resistance of the shoreline or the breakwater can be reduced during construction, and the manufacturing cost of the port shoreline or the breakwater is further reduced.
