Specific embodiment

The present invention is described further with reference to the accompanying drawing.

The present invention is based on prior art, proposes a kind of increase oscillating water column (OWC) for the deficiency in art methods The method of device wave energy capture bandwith, main purpose, which is to design, a kind of has higher wave energy extraction efficiency, wider array of The oscillaton water column type wave energy apparatus of effective frequency belt width.

A kind of oscillaton water column type wave energy apparatus with larger wave energy capture bandwith is mainly made of following system: gas chamber Control system, wave detection system and OWC Wave energy generating system.Be characterized mainly in that gas chamber control system: signal receives dress Set 9, hydraulic device 10 and intermediate mediastinum wall 2.Signal receiving device 9 is mounted on 12 top of OWC device top plate, and hydraulic device 10 is pacified Between top plate 12 and intermediate mediastinum wall 2, to drive intermediate mediastinum wall 2.Control system principle: gas chamber width and gas are based on The relationship of indoor water body intrinsic frequency adjusts intermediate mediastinum wall 2 by hydraulic device 10, and then adjusts gas chamber width to adapt to wave Unrestrained frequency makes water body in gas chamber occur to resonate to realize the optimal of wave energy capture efficiency with incidence wave.Signal receiving device 9 will connect The incident frequency signal of receipts is converted into displacement signal, then drives hydraulic device 10 using displacement electric signal.Hydraulic device 10 Movement changes position such as Fig. 1 dotted line of intermediate mediastinum wall 2, adjusts water body intrinsic frequency in forward and backward gas chamber, optimal to obtain Catching can efficiency.The transmitting of synchronous signal has real-time, can guarantee that OWC gas chamber adjusts water body intrinsic frequency in gas chamber in time.

The movement of intermediate mediastinum wall: intermediate mediastinum wall 2 is located inside OWC, embedded by arranging in two sides cross wall 11 Slideway 13 and hydraulic device 10 are fixed, and to separate two gas chambers, the movement of intermediate mediastinum wall be can change in two gas chambers Water body intrinsic frequency.Intermediate mediastinum wall 2 moves (change in location along the embedded slideway 13 in two sides under the driving of hydraulic device 10 As indicated by a broken line in fig. 1), guarantee that water column realizes resonance under the wider array of wave condition of frequency range in gas chamber.When hydraulic device 10 After receiving signal receiving device 9 treated displacement signal, hydraulic device 10 drives intermediate mediastinum wall 2 in real time, makes its edge Embedded slideway 13 in two sides cross wall 11 be moved to optimum position to guarantee utmostly to obtain wave energy.

Embedded slideway arrangement: embedded slideway is arranged in two sides cross wall 11, is made of upper and lower two slideways, with liquid Pressure device 10 supports intermediate mediastinum wall 2 jointly.It is simutaneously arranged two embedded slideways 13 and locking device is set to ensure that wave is made It will not be subjected to displacement and be rotated with lower intermediate mediastinum wall 2.Embedded slideway 13 should be according to local sea situation and gas chamber internal resonance wave Unrestrained situation considers arrangement, avoids directly contacting with seawater, to improve the survival ability and durability of OWC device.Work as driving device After 10 control intermediate 2 arrival optimum position of mediastinum wall, the shifting of intermediate mediastinum wall 2 is limited by the locking device on embedded slideway 13 It is dynamic, it is ensured that intermediate mediastinum wall 2 will not be subjected to displacement and rotate under wave action.
