Technical Field

[0001] This invention relates to the field of marine energy harvesting, and more particularly to an integrated power device for marine-powered vessels. Background Technology

[0002] The ocean is rich in renewable energy resources, primarily including tidal energy, wave energy, ocean current energy, thermal gradient energy, salinity gradient energy, and marine biomass energy. More broadly, marine renewable natural resources also include wind and solar energy on the ocean surface. In recent years, with the increasing depletion of traditional fossil fuels and the urgent advocacy for low-carbon emission reduction, countries worldwide have placed greater emphasis on the development of marine renewable energy. Today, various ocean energy power generation technologies have seen significant improvements.

[0003] Using the ocean's own energy for navigation has been a long-standing human goal, but research on ships that utilize multiple ocean renewable energy sources is still scarce, and research on integrating collected ocean energy to propel ships is even rarer.

The sliding transmission switching mechanism of the duckweed mechanical energy input shaft cooperates with the second ratchet mechanism and the second DC generator coupling, respectively.

[0012] Furthermore, the sliding transmission switching mechanism includes an electrically controlled push-pull device and a helical gear sleeve that are linked together. The helical gear sleeve is slidably mounted on the wind column mechanical energy input shaft and the duckweed mechanical energy input shaft. Both ends of the helical gear sleeve are provided with first helical gear transmission wheels. The first helical gear transmission wheel at one end meshes with the first ratchet mechanism and the second ratchet mechanism, while the first helical gear transmission wheel at the other end meshes with the second helical gear transmission wheels on both the first DC generator connecting shaft and the second DC generator connecting shaft.

[0028] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] Example

[0030] Specific embodiments of the present invention are as follows: Figures 1 to 3As shown, a marine-powered propulsion system for a vessel includes a wave vertical energy collector 6 and a wind energy collection column 4. Both the wave vertical energy collector 6 and the wind energy collection column 4 are linked to the same energy collection drive shaft 1. The energy collection drive shaft 1 has a power output end that is linked to the propeller of the vessel. At least one of the wave vertical energy collector 6 and the wind energy collection column 4 is also linked to a DC generator. The propeller is located at the stern of the vessel.

[0031] The integrated power unit for the marine-powered vessel also includes a fuel engine 80, whose mechanical energy input shaft 8 is linked to the energy collection drive shaft 1. A sliding transmission switching mechanism 7 is provided on the fuel engine mechanical energy input shaft 8. A third ratchet mechanism 15 is provided on the energy collection drive shaft 1, and the sliding transmission switching mechanism 7 cooperates with the third ratchet mechanism 15.

[0032] In this embodiment, both the vertical energy harvester 6 and the wind energy harvesting column 4 are linked to DC generators. The DC generators include a first DC generator 510 and a second DC generator 520. The first DC generator 510 is equipped with a first DC generator coupling 51, and the second DC generator 520 is equipped with a second DC generator coupling 52. The energy collection drive shaft 1 is equipped with a first ratchet mechanism 13 and a second ratchet mechanism 14. The wind energy harvesting column 4 is linked to a wind column mechanical energy input shaft 41, and the vertical energy harvester 6 is linked to a duckweed mechanical energy input shaft 61. Both the wind column mechanical energy input shaft 41 and the duckweed mechanical energy input shaft 61 are equipped with sliding transmission switching mechanisms 7. The sliding transmission switching mechanism 7 of the wind column mechanical energy input shaft 41 cooperates with the first ratchet mechanism 13 and the first DC generator coupling 51, respectively. The sliding transmission switching mechanism 7 of the duckweed mechanical energy input shaft 61 cooperates with the second ratchet mechanism 14 and the second DC generator coupling 52, respectively.

[0033] The sliding transmission switching mechanism 7 includes an electrically controlled push-pull device 72 and a helical gear sleeve 71 that are linked together. The helical gear sleeve 71 is slidably mounted on the wind column mechanical energy input shaft 41 and the duckweed mechanical energy input shaft 61. Both ends of the helical gear sleeve 71 are provided with first helical gear transmission wheels. One end of the first helical gear transmission wheel meshes with the first ratchet mechanism 13 and the second ratchet mechanism 14, while the other end of the first helical gear transmission wheel meshes with the second helical gear transmission wheels on both the first DC generator connecting shaft 51 and the second DC generator connecting shaft 52. The electrically controlled push-pull device 72 can be a linear motor or a hydraulic telescopic cylinder. By driving the helical gear sleeve 71 to slide along the axis through the electrically controlled push-pull device 72, the direction of power transmission can be switched.

[0034] In this embodiment, the sliding transmission switching mechanism 7 on the fuel engine mechanical energy input shaft 8 has the same structure and principle as the sliding transmission switching mechanism 7 on the wind column mechanical energy input shaft 41. The first ratchet mechanism 13, the second ratchet mechanism 14, and the third ratchet mechanism 15 are all unidirectional transmission structures, and their working principle is the same as that of the unidirectional transmission ratchet mechanism connected to the bicycle pedal.

[0035] The vertical energy harvester 6 includes a hydraulic cylinder 65 and a float hydraulic linkage 64, which are movably connected. The float hydraulic linkage 64 is connected to a float 63, and the float 63 is slidably connected to a float positioning slide rod 62. The float positioning slide rod 62 is fixedly connected to the hull and arranged vertically. The oil outlet of the hydraulic cylinder 65 is sequentially connected to a pressure oil pipe 66, a hydraulic oil pressure stabilizing tank 68, a first high-pressure turbine 691, and a return oil pool 695. The output shaft of the first high-pressure turbine 691 is also the floating mechanical energy input shaft 61. The return oil pool 695 is connected to the return oil end of the hydraulic cylinder 65 via a return oil pipe 67, allowing the hydraulic oil to circulate. A first one-way valve 661 and a second one-way valve 671 are respectively installed on the pressure oil pipe 66 and the return oil pipe 67. The one-way valves prevent the hydraulic oil in the pipes from flowing back.

[0036] A second high-pressure water turbine 692, connected in parallel with the first high-pressure water turbine 691, is also provided between the hydraulic oil pressure stabilizing tank 68 and the return oil pool 695. The second high-pressure water turbine 692 is linked to a third DC generator 693. The output ends of both the second high-pressure water turbine 692 and the first high-pressure water turbine 691 are connected to the return oil pool 695 through oil outlet pipes 694.

[0037] Both the second high-pressure water turbine 692 and the first high-pressure water turbine 691 are equipped with self-controlled solenoid valves at their input ends to ensure that the impact pressure of the hydraulic oil on the high-pressure water turbine is limited.

[0038] The float 63 can move up and down with the waves, thereby driving the hydraulic oil in the hydraulic cylinder 65 through the hydraulic linkage 64. The hydraulic oil flows in a fixed direction through the pressure oil pipe 66, the hydraulic oil pressure stabilizing tank 68, the first high-pressure water turbine 691, the second high-pressure water turbine 692, the return oil pool 695, and the return oil pipe 67. While driving the propeller to rotate through the floating mechanical energy input shaft 61, it can also generate electricity through the third DC generator 693. This part of the electrical energy is used for power supply of the ship's living facilities.

[0039] The wind energy collection column 4 includes an impeller and a vertical shaft 40 that are linked together. The vertical shaft 40 is connected to a first bevel gear 42 arranged coaxially with it.

[0040] There are multiple wind energy harvesting columns 4. At least two wind energy harvesting columns 4 have their first bevel gears 42 linked to the same second drive shaft 43 via a first bevel gear shaft 44. The second drive shaft 43 is linked to the wind column mechanical energy input shaft 41 via a bevel gear set 45. The first bevel gear shaft 44 has a second bevel gear and a third bevel gear at each end, and the second drive shaft 43 has a fourth bevel gear. The second bevel gear on the first bevel gear shaft 44 meshes with the first bevel gear 42, and the third bevel gear on the first bevel gear shaft 44 meshes with the fourth bevel gear on the second drive shaft 43.

[0041] When the ship is sailing at sea, the sea breeze blows the impeller of the wind energy collection column 4, causing it to rotate. The impeller drives the vertical shaft 40 to rotate, and the vertical shaft 40 is rotatably connected to the hull. The first bevel gear 42 rotates together with the vertical shaft 40, and drives the wind column mechanical energy input shaft 41 to rotate in sequence through the first bevel gear shaft 44, the second transmission shaft 43, and the bevel gear set 45.

[0042] The marine energy ship integrated propulsion system of this scheme not only includes the energy transmission of the wave vertical energy harvester 6 and the wind energy harvesting column 4, but also includes a fuel engine 80, which uses multiple methods to drive power generation, thus extending the cycle of marine operations and enhancing the seaworthiness of the ship.

[0043] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
