Fig. 5 is an isometric view of the reverse differential combined water turbine 3. The reversing differential combined water turbine 3 comprises a water turbine assembly and a planetary gear assembly 4. The turbine assembly includes an upper lift three-bladed turbine 31 having high tip speed ratio, high efficiency characteristics, but poor self-starting performance. The upper end and the lower end of the rotor are provided with two end plates, the end plates have the functions of reducing the flow loss of the tips of the blades and simultaneously being fixing devices of the blades, and the end plates are adopted to fix the blades more reliably under water; meanwhile, a semicircular two-blade water turbine 33 is arranged in the upper lift type three-blade water turbine 31, and the rotor is also fixed by an end plate of the upper lift type three-blade water turbine 31. The two rotors rotate simultaneously, the diameter of the two-blade water turbine 33 is half of that of the upper lift type three-blade water turbine 31, so that the starting performance of the two-blade water turbine 33 can be exerted, the performance of the upper lift type three-blade water turbine 31 is less influenced, and the two water turbines are connected with the sun gear 41 of the planetary gear device 4; the lower resistance type multi-blade water turbine 32 has a low tip speed ratio, high starting characteristics, but is low in efficiency, the blades of the rotor are also fixed by two end plates, and the moment of the lower resistance type multi-blade water turbine 32 is transmitted by a cylindrical cavity connected with the outer gear ring 43. Due to the torque synthesis characteristic of the planetary gear mechanism 4, the input torque (M1) of the sun gear 41 and the input torque 43 (M2) of the outer gear ring can be synthesized and then input to the planet gear 42, wherein the synthesis relationship is M1/r1+m2/r2=m/(r1+r2), wherein R1 is the radius of the sun gear 41, and R2 is the radius of the outer gear ring 43. The biggest innovation point of the combination of the planetary gear mechanism 4 and the reversing differential combined water turbine 3 is that the characteristics of high rotating speed and high efficiency of the upper lift type three-blade water turbine 31 and the characteristics of low rotating speed and high starting performance of the lower resistance type multi-blade water turbine 32 are taken into consideration, so that two rotors with larger optimal running speed difference can run under respective suitable working conditions, the functions of reversing and differentiating are realized, and the moment of two non-coaxial rotors is synthesized on one rotating shaft. Another innovation of the planetary gear 4 and the reverse differential combined water turbine 3 is that the size of the rotor is smaller than that of the planetary gear mechanism, and the design of the mechanism only needs to meet the transmission ratio of the sun gear 41 and the outer gear ring 43 and the strength requirement of the mechanism, under the condition that the radius of the rotor can be enlarged.
Fig. 5 is a surface isometric view of the reversing differential combined turbine 3, and the installation of three rotors can be seen, wherein the lower end plate of the upper lift three-bladed turbine 31 is kept in clearance with the upper end plate of the lower resistance multi-bladed turbine 32, and the lower end plate of the lower resistance multi-bladed turbine 32 is kept in clearance with the upper magnetic transmission device 51.
Fig. 7 is an internal assembly view of a planetary gear mechanism in which a sun gear 41 is connected to a central shaft of an upper lift type three-blade hydraulic turbine 31, an outer gear ring 43 is connected to a central cylindrical cavity of a lower resistance type three-blade hydraulic turbine 42, a planetary gear 42 capable of rotating only synthesizes input torque of the sun gear 41 and the outer gear ring 43, and the input torque is transmitted to a sun gear 45 by a gear at the end of a gear transmission rod 44, the sun gear 45 is connected to an upper magnetic transmission device 51, and finally the torque is transmitted to a lower magnetic transmission device 52, and a generator 61 is driven to generate power. The structure of the gear at the end of the gear transmission rod 44 is the same as the planetary gear 43, and the structure of the sun gear 45 is the same as the sun gear 41.
Fig. 8 is an isometric perspective view of a magnetic levitation support device. The outer structure of the magnetic suspension supporting device 2 consists of a supporting device shell 21, and the inner structure of the magnetic suspension supporting device 2 consists of an outer passive permanent magnetic suspension bearing 22, an inner passive permanent magnetic suspension bearing 23 and a top device 24. The external passive permanent magnetic suspension bearing 22 is nested inside the supporting device shell 21, and the internal passive permanent magnetic suspension bearing 23 is arranged outside the top 24. The outer passive permanent magnetic suspension bearing 22 and the inner passive permanent magnetic suspension bearing 23 are magnetized by radiation, and the inner part and the outer part of the circular ring are respectively provided with different magnetic poles. Wherein the outer part of the inner ring and the inner part of the outer ring have the same magnetic field. The inner ring of the passive permanent magnetic suspension bearing 22 is connected with the central shaft end part of the reversing differential combined water turbine 3 through a top 24, and the outer ring of the passive permanent magnetic suspension bearing 22 is arranged on the supporting device shell 21 so as to be connected with the upper end of the collecting water turbine mounting device 9, and radial stabilizing force is generated by utilizing the magnetic field effect. The contact of the tip 24 with the support device housing 21 generates an axial stabilizing force, thereby fixing the position of the reverse differential combined water turbine 3 so that it can rotate only in the axial direction.
Fig. 9 is a top view of the upper magnetic actuator 51 and the lower magnetic actuator 52. The magnetic transmission device 5 consists of two groups of permanent magnets which are symmetrically arranged at the center, wherein the magnetizing modes of the permanent magnets are the thickness direction magnetizing, and the magnetic pole installing modes of the adjacent permanent magnets are opposite. The upper magnetic transmission device 51 is installed on the lower bottom surface of the reversing differential combined water turbine 3, is connected with the central gear 45, and the lower half part of the lower magnetic transmission device 52 is installed inside the low-resistance sealing cavity 6 and is coaxially connected with the permanent magnet generator 61. The magnetic pole installation direction of the permanent magnet is opposite to the installation direction of the adjacent permanent magnet. Due to the principle that opposite poles attract each other and the like repel each other, torque can be transmitted under the condition that dislocation is generated by magnetic transmission. The non-contact transmission can cut the dynamic seal assembly, so that the low-resistance seal cavity 6 adopts integral static seal, and the leakage risk is greatly reduced. In addition, the ratio of the rotating speeds of the upper part and the lower part of the magnetic transmission device is equal to the number of magnetic poles of the upper part and the lower part of the magnetic transmission device, so that different speed increasing ratios can be realized by controlling the number of the magnetic poles, and the easily-lost part of the speed increaser (gearbox) can be cut. Further increasing the stability and reliability of the system.

Fig. 11 is a front view (left) and a side view (right) of a posture adjustment of a moored deep sea observation system. When the moored deep sea observation system is facing the incoming flow (left diagram of fig. 11), the power generation device suspended in the deep sea is subjected to the buoyancy of the floating body, the gravity of the gravity block, the fluid resistance and the tensile force of the deep sea cable. Because the flow speed of ocean currents changes, the whole floating system can generate overturning vibration, and when the floating system is inclined, the gravity block and the buoyancy are not in a straight line, so that moment opposite to the inclined posture is generated. The reverse differential combined water turbine 3 mainly comprises an upper rotor and a lower rotor which are reversed, the moment directions of the two rotors are opposite, and the deflection of the device facing the incoming flow direction (right diagram of fig. 11) is reduced.

The deep sea base station and the floating ocean current energy power generation system are lowered via a research ship and the deep sea base station is installed and fixed to the seabed. Single or several autonomous underwater vehicles are released by research vessels to the nearby sea area to cruise in the vicinity of the deep sea base station. The autonomous underwater vehicle measures the long-term hydrographic data using the observation system 143 installed therein. The deep sea base station uses the sensor system 12 therein to measure long-term hydrographic data. The reverse differential combined water turbine 3 rotates under the action of water flow, kinetic energy in the ocean current is converted into mechanical energy of the reverse differential combined water turbine 3, and the mechanical energy is transmitted to the generator 61 through the magnetic transmission device 5, so that the mechanical energy is converted into electric energy and transmitted to the energy storage device 62 to be stored in a chemical energy form. And transmits energy to the underwater base station through the underwater cable 10. Under the condition of lower energy level of the underwater autonomous vehicle, the underwater autonomous vehicle moves to the vicinity of the deep sea base station to be in butt joint with the wireless charging device and the connection device 11, and electric energy in the deep sea base station is transferred into the underwater autonomous vehicle through wireless charging, so that the underwater autonomous vehicle cruises for a long time. While the hydrologic data measured by the sensor system 12 in the deep sea base station is transmitted to the autonomous underwater vehicle by means of wireless data transmission.
