Seawater directly drive with the energy collecting device of contact with sea water the research for collecting the energy and application had more technology
Type, such as the transmission of direct machine driving, low pressure, high-pressure and hydraulic transmission, pneumatic gearing, but be all distributed in mostly coastal
Or offshore area, and device volume is huge.The device development for collecting wave energy indirectly is later, and existing type is simultaneously few.
Currently, the device of this indirect collection wave energy is integrated in sea to monitor and develop the needs of ocean by the mankind
In upper detection instrument, such as on oceanographic buoy, sail device equipment platform, energy receipts can be carried out in non-coastal offshore area

The reason of middle vibrational waveform complexity, so that the frequency of friction material surface being contacting and separating is lower, and mutual Rigid Body Impact
Extreme loss energy, friction are allowed to the lost of life, so the lower service life of electric energy of output is not grown.
Since wave vibration has the characteristics that frequency is extremely low in ocean, generally less than 5Hz, or even in 1Hz hereinafter, existing
The output power of the oscillatory type energy collecting device of the types such as Electromagnetic generation, triboelectricity is heavily dependent on vibration frequency
Height, high power density output and higher energy conversion efficiency are difficult to realize under superlow frequency vibrating environment.Due to ocean wave
The unrestrained reason of vibrational waveform complexity and existing apparatus structure oneself factor in space, mostly can only be in single-degree-of-freedom or minority
This part kinetic energy is moved and collected in several freedom degrees, and the ocean wave energy of rest part can only waste.For that can integrate
At sea equipment platform collects the device of wave energy indirectly, lacks efficient apparatus and technology at present to realize to the abundant of wave energy
Using and collect.
Therefore, the efficiency for how improving wave-energy collection, is a technical problem that technical personnel in the field need to solve at present.
