Abstract: 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.

Abstract: 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.

Abstract: A wave-direction-adaptive wave focusing type wave energy convertor with multiple water channels, comprising an energy acquisition system, an energy conversion system and a support system. Wave focusing is carried out through double water channels, so that the movement amplitude of water particles behind a box is doubled. A device is connected with a fixed pile through universal bearings, so that an opening of the device is always faced to a wave flow direction, which adapts to different seasons and water conditions, has low environmental requirements, and can be used in a wide sea area. Several coils of pretension spring compression are arranged in a winding barrel, so that a nylon rope connected to a buoy is ensured to be always in a straightened state and not derail from pulley blocks to work abnormally due to looseness whether the buoy is at a wave crest or a wave trough.
