Technical Field

[0001] This invention belongs to the field of deep-sea observation technology, and specifically relates to a permanent deep-sea observation system based on a wave energy conversion device. Background Technology

[0002] The exploration and development of the ocean, especially the deep sea, depends on the development of marine science and technology. The emergence of any marine scientific perspective and the development of marine disciplines must be based on reliable observational data. Autonomous underwater vehicles (AUVs) are a new type of mobile marine environmental observation equipment. They possess autonomous power and navigation systems and can be equipped with various sensors to conduct dynamic and three-dimensional observations of the marine environment. However, due to limitations in battery capacity, the operating range and time of AUVs are very limited, requiring ship-based recovery stations for energy replenishment. This significantly restricts the observation range of AUVs and greatly increases observation costs. Summary of the Invention

[0003] The purpose of this invention is to provide a permanent deep-sea observation system based on a wave energy conversion device to solve the problem of energy replenishment difficulties for autonomous underwater vehicles operating in the deep sea.

The wave energy conversion device is connected to the deep-sea base station via the underwater cable, and the deep-sea base station is used to provide power to the underwater autonomous vehicle.

[0006] Furthermore, the wave energy conversion device is a piston-type wave energy conversion device.

[0013] Compared with the prior art, the present invention has the following technical effects:

[0014] This invention proposes a deep-sea observation system based on a wave energy conversion device. This observation cluster, based on the wave energy conversion device, consists of an underwater autonomous vehicle (AUV), a deep-sea base station, underwater cables, and the wave energy conversion device. The deep-sea base station utilizes a piston-type wave energy conversion device to convert surface wave energy into electrical energy, which powers the various observation equipment mounted on the base station via underwater cables. It can also power the AUV and buoy system via wireless power supply devices and a connection system. Using this invention, continuous observation of ocean energy can be achieved without receiving any ship-based or shore-based energy replenishment. Attached Figure Description

Figure 2 This is a front view of a resident deep-sea observation system based on a wave energy conversion device. Figure 3 This is a perspective front view of a permanent deep-sea observation system based on a wave energy conversion device. The piston-type wave energy conversion device 1 is connected to the deep-sea base station 3 via an underwater cable 2.

[0029] Figure 4 This is an isometric drawing of a piston-type wave energy conversion device. Figure 5 This is a perspective axonometric view of a piston-type wave energy conversion device. The piston-type wave energy conversion device 1 consists of a rack 11, a support device 12, a generator 13, a communication antenna 14, a piston 15, and a cylindrical housing 16. The rack 11 is connected to the piston 15, and the generator 13 is mounted on the upper part of the cylindrical housing 16, with the rack 11 in contact with the generator 13. Under the action of ocean waves, the piston device reciprocates within the cylindrical housing 16, thereby driving the rack 11 to move up and down, which in turn drives the generator to rotate. The support device 12 contacts the rack 11 and provides support. The communication antenna 14 is mounted on the side of the cylindrical housing 16.

[0030] The underwater device of the permanent deep-sea observation system based on wave energy conversion device consists of an underwater cable 2 and a deep-sea base station 3. Figure 6 This is the front view of the underwater device. Figure 7 This is a perspective front view of the underwater device. Figure 8 This is a side view of the underwater device. Figure 9 This is a perspective side view of the underwater device. One end of the underwater cable 2 is connected to the deep-sea base station, transferring the energy generated by the piston-type wave energy conversion device 1 to the deep-sea base station 3. The deep-sea base station consists of a pressure-resistant shell 31, an energy storage and control system 32, a wireless charging and connection device 33, and a sensor system 34. The wireless charging and connection device 33 and the sensor system 34 are mounted on the side of the pressure-resistant shell 31, while the energy storage and control module 32 is installed inside the pressure-resistant shell 31. The energy storage and control module 32 provides power to the wireless charging and connection device 33 and the sensor system 34.

[0031] Figure 10This is an isometric view of the underwater autonomous vehicle 4.

The sensor system 42 is installed on the upper part of the underwater autonomous vehicle body 41.

[0032] Figure 11 This is a schematic diagram of a permanent deep-sea observation system based on a wave energy conversion device. A deep-sea base station 3 is lowered, installed, and fixed to the seabed by a research vessel. One or more autonomous underwater vehicles (AUVs) 4 are released by the research vessel to a nearby sea area and cruise near the deep-sea base station 3. Each AUV 4 carries a detection device to measure long-term hydrological data. A piston-type wave energy sensor system 1 converts kinetic energy into electrical energy under the influence of waves, and transfers this energy to the deep-sea base station 3 via an underwater cable 2. The system then connects to the AUVs 4 via a wired charging device and a docking device 33, wirelessly transferring electrical energy from the deep-sea base station to the AUVs 4, enabling the AUVs 4 to cruise for extended periods and transmit hydrological information to the deep-sea base station wirelessly. This operation can also be achieved by using one deep-sea base station 3 in conjunction with several AUVs 4, or by using multiple deep-sea base stations 3 in conjunction with several AUVs 4, to achieve higher system stability. The deep-sea base station uploads data to the satellite via a piston-type wave energy sensor system 1 that floats on the water surface, and receives real-time control commands from the satellite via a buoy.
