Referring to fig. 1 to 10, a submarine power supply system based on a reverse combined water turbine comprises a bracket 1, a supporting device 2 and a combined reverse water turbine 3, wherein the combined reverse water turbine 3 comprises an upper three-blade H-shaped water turbine 31, a lower resistance type multi-blade water turbine 32, a lifting type three-blade water turbine 31, two-blade water turbines 33 inside the lower resistance type multi-blade water turbine 32 and the lifting type three-blade water turbine 31, a planetary gear mechanism 4, magnetic transmission devices 5 on two sides of a rotating shaft, a static seal cavity 6, a generator 61, a rechargeable battery 62, an underwater vehicle 7, a wireless charging and plugging device 8, a gravity base 9, a sensor system 10, a buoy sensor system 11, an underwater cable 12 and a buoy 13.
The core technology of the invention is to provide a reverse rotation type water turbine based on a planetary gear device, and the combination of a multi-blade water turbine with low rotation speed and high self-starting performance and a H-shaped water turbine with high rotation speed and high efficiency is realized by utilizing the rotation speed difference between a sun gear and a gear ring and the torque synthesis of a planet gear, so that the device has the characteristics of low flow speed starting and high efficiency power generation. Meanwhile, based on the characteristics of the planetary gear, the torque of two independent water turbines with different rotational speeds is synthesized to the planetary gear, so that the power generation of the single-generator motor is realized, and the rotational speed of the generator is also improved. Finally, the water turbine is installed in an underwater monitoring unit to serve as a power generation end.
Fig. 1 is a system assembly diagram, wherein a bracket 1, a static seal cavity 6 and a gravity base 9 are integrally formed. A half magnetic transmission device 5, a generator 61 connected with the magnetic transmission device and an energy storage battery 62 are arranged in the static seal cavity 6; the wireless charging and plugging device 8 and the sensor system 10 are arranged on the side surface of the bracket 1, and the buoy sensor system is arranged above the bracket 1; the support and the gravity base realize the axial and radial support of the combined water turbine 3 through two supporting devices 2. The other half of the magnetic transmission device is arranged on the bottom end plate of the H-shaped water turbine, and the non-contact transmission is realized through magnetic force, so that the use of a dynamic sealing technology under water is avoided. The underwater vehicle 7 can be charged and cruised at the power generation base station by the wireless charging and docking device 8, and can be data-transmitted by the sensor system 10, and can be transmitted to the command unit together with the data of the buoy sensor system 11 by the buoy 13.
Fig. 2 is a partial perspective view of a power generation unit, i.e. a combined counter-rotating water turbine 3, and a transmission unit, the combined counter-rotating water turbine 3 being supported axially and radially by a support device 2 at the upper end of the stand and a support device 2 at the static seal cavity.

Fig. 3 is an isometric perspective view of the core innovation of the present invention, a combined counter-rotating turbine. The combined counter-rotating turbine comprises a combined counter-rotating turbine 3 and a planetary gear assembly 4. The combined counter-rotating turbine comprises a three-blade H-shaped water turbine 31, has the characteristics of high tip speed ratio and high efficiency, but has poor self-starting performance. The upper end and the lower end of the water turbine 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 water under water more reliably; meanwhile, a semicircular-blade water turbine 33 is installed inside the three-blade H-shaped water turbine 31, and the water turbine is also fixed by an end plate of the three-blade H-shaped water turbine 31. The two water turbines rotate simultaneously, the diameter of the semicircular blade water turbine 33 is half of that of the three-blade H-shaped water turbine 31, so that the starting performance of the semicircular blade water turbine 33 can be exerted, the performance of the three-blade H-shaped water turbine 31 is less influenced, and the two water turbines are connected with the sun gear 41 of the planetary gear device 4; below is a drag type multi-blade turbine 32 having a low tip speed ratio, high start-up characteristics, but low efficiency, the blades of which are also fixed by two end plates, connected to an outer gear ring 43. Due to the torque combining feature of the planetary gear mechanism, the input torque (M1) of the sun gear 41 and the input torque 43 (M2) of the outer ring gear can be input to the planet gear 42 in a combined mode, wherein the combined mode 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 ring gear 43. The biggest innovation point of the planetary gear mechanism and reversing differential water turbine combination is to combine the characteristics of high rotation speed and high efficiency of the three-blade H-shaped water turbine 31 and the characteristics of low rotation speed and high starting performance of the resistance type multi-blade water turbine 32, so that the two water turbines with larger optimal running speed difference can run under the respective suitable working conditions, the functions of reversing and differentiating are realized, and the moments of the two non-coaxial water turbines are combined on one rotating shaft. Another innovation of the combination of the planetary gear and the reversing differential turbine is that the size of the planetary gear mechanism is smaller than that of the turbine, 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 turbine can be enlarged.
Fig. 4 is a surface perspective view of the combined counter-rotating turbine, and the installation mode of three turbines can be seen, wherein the lower end plate of the three-blade H-type turbine 31 keeps a gap with the upper end plate of the resistance-type multi-blade turbine 32, and the lower end plate of the resistance-type multi-blade turbine 32 keeps a gap with the upper magnetic transmission device 51.
Fig. 5 is a schematic view of the inside of a planetary gear structure, in this mechanism, a sun gear 41 is connected with the central shaft of a three-blade H-shaped water turbine 31, an outer gear ring 43 is connected with a central cylindrical cavity of a resistance-type multi-blade water turbine 42, a planetary gear 42 capable of rotating only synthesizes input torque of the sun gear 41 and the outer gear ring 43, the input torque is transmitted to a sun gear 45 by a gear at the tail end of a gear transmission rod 44, the sun gear 45 is connected with an upper magnetic transmission device 51, and finally the torque is transmitted to a lower magnetic transmission device 52 and drives a generator 61 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. 6 is an isometric perspective view (left) and an internal structural perspective view (right) of the magnetic levitation supporting 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 combined reversing 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 bracket 1, 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 combined counter-rotating turbine 3 so that it can rotate only in the axial direction.
Fig. 7 is a top view of the upper magnetic actuator 51 (left) 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 arranged on the lower bottom surface of the combined reversing water turbine 3, and the lower half part of the magnetic transmission device 5 is arranged inside the static seal cavity 6 and is coaxially connected with the permanent magnet generator. 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 static 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.
