摘要： The present invention relates generally to the offshore renewable energy utilization technology. A novel floating wind-wave integrated power generation system is based on the braceless semi-submersible floating wind turbine concept and the oscillating water column (OWC) wave energy generator. The integrated system includes the offshore wind energy system and the oscillating water column wave energy system. The novel floating wind-wave integrated power generation system transfers the rise and fall movement of the water column into the air in and out movement which is converted into the electricity by the air turbine generator. This invention makes good use of pontoons at of the semi-floating platform and the mooring lines. Since the wave energy system will move with the wave movement, which will reduce the power generation efficiency. The pontoon can help to mitigate this movement. The mooring system can further prevent the movement of the wave energy device. This invention uses the braceless structure, which simplifies the construction process and reduce the fatigue issues for the braces. Compared with the traditional three columns semi-submersible wind turbine, this invention enlarges the water plane area. The moment of inertia for hydrostatic stability is enhanced, and the stability of the floating foundation is improved.

摘要： The present disclosure discloses a time synchronous hybrid analog and digital sensor data acquisition system and method, comprising analog sensors, digital modules, digital sensors, hubs for networking a plurality of heterogeneous sensors, a local-area network device and a data processing terminal. The present disclosure solves the problem that data cannot be compared due to time difference in acquisition for the reason that the sampling time of different sensors cannot be synchronized precisely in the existing experiments and practical engineering, and also solves the problems of single function, low integration level and manpower consumption when different sensor instruments work separately. The data acquisition system of the present disclosure can be directly connected to various heterogeneous sensors to realize synchronous acquisition, synchronous transmission and simple and fast operation. The present disclosure greatly increases the time precision, amplitude precision and efficiency of synchronous acquisition, reduces the labor cost, and has wide application prospect.

摘要： A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.

摘要： A wave energy thermal storage type seawater thermoelectric power generation device which comprises a buoy-type energy capture system, a platform system and a mooring system. A whole friction liquid heating, thermal storage and power generation device is arranged inside a platform, which improves the adaptability of the whole system to the external environment. A flywheel and liquid friction heating method is adopted to generate heat more efficiently. Inner ratchets and pawls are used to control the movement of a flywheel so that the flywheel always rotates in one direction, and when the rotating speed of the flywheel exceeds that of the inner ratchets, the external wave energy cannot be transferred to the flywheel through the movement of the inner ratchets so as to limit the upper limit of the rotating speed of the flywheel and protect the safety of the flywheel system.

摘要： An active tuned mass damper applied to the offshore monopile wind turbine belongs to the field of marine technology. A mass block is connected to the inner wall of the tower through a spring. The two ends of the damper and the force actuator are connected to the mass block and the inner wall of the tower, respectively. When the installation of tower is finished, the spring and the damper begin to work. The movement of mass block will partly offset the movement of the tower caused by the wave force. The force actuator starts to work before the mating. The exact position of the nacelle can be obtained from the Global Positioning System (DGPS). The position of tower can be adjusted in the horizontal plane through the force actuator. So, the offshore installation time for nacelle will be saved. The whole installation time and cost will also be reduced.

摘要： The present invention provides an oscillating water column-oscillating buoy combined wave energy converter. The present invention combines the advantages of the wave energy converters of the oscillating water column and the oscillating buoy. The conversion principles of wave energy of the oscillating water column and the oscillating buoy are on the contrary. The oscillating water column works when the structure does not move, while the oscillating buoy works when the structure substantially vibrates. The oscillating water column and the oscillating buoy are respectively operated in respective spectral ranges without affecting each other, thereby expanding the effective frequency band width of wave energy conversion. Due to the characteristic of absorbing the wave energy at all directions of 360°, the absorption efficiency of the wave energy is enhanced. Through the adoption of a fixed structure, stability of the converter can be ensured, generating efficiency is enhanced and maintenance is facilitated.
