These two energy sources can be coupled and output, increasing unit energy output, improving ocean space utilization, smoothing power output fluctuations, and reducing construction and maintenance costs. Publication number (CN116146410A) provides a dual-buoy wave energy generation device, which uses dual-buoy power generation components that undergo relative helical motion under wave force to achieve simultaneous power generation by the dual-buoy power generation components.

[0003] However, the aforementioned dual-buoy wave energy generation device floats on the sea surface, has low wind resistance and poor stability; and has few points that can generate electricity, resulting in low power generation efficiency.

[0004] More importantly, the aforementioned dual-buoy wave energy generation device can only absorb wave energy but cannot absorb ocean current energy, resulting in low energy utilization per unit area of ​​the ocean. Summary of the Invention

Example 2

[0034] A power generation method for a wave-current combined power generation platform includes the following steps during the power generation process.

[0035] The cylindrical box-type power generation module shall at least achieve the following steps: S11, When the upper shell 5 of the float floats with the wave current, a relative height difference is generated between the upper shell 5 of the float and the cylindrical box 8; S12, when the connecting rod 1 swings near one end of the float upper shell 5, the connecting rod 1 drives the transmission rod 83 to swing around the input end of the bidirectional generator 87 with the pin 84 as the fulcrum, and drives the input end of the bidirectional generator 87 to rotate. S13, bidirectional generator 87 starts generating electricity.

[0036] The wave power generation components shall at least achieve the following steps: S21, when the upper shell 5 of the float floats with the wave current, the upper shell 5 of the float starts to swing with the contact point between the second support rod 4 and the connecting rod 1 as the fulcrum, and drives the reciprocating rod 2 to move up and down reciprocally under the limit of the first support rod 3. S22, the reciprocating rod 2 drives the two swing rods 111 and 112 to rotate around the ratchet 114 in opposite directions. The pawls 115 on the clockwise rotating swing rods 111 and 112 will slide relative to the teeth of the ratchet 114 and will not push the ratchet 114 to rotate. The pawls 115 on the counterclockwise rotating swing rods 111 and 112 will push the ratchet 114 to rotate counterclockwise. At this time, the ratchet 114 will drive the main shaft 12 to rotate in one direction. S23, the unidirectional rotation of the main shaft 12 can drive the worm wheel 121 to rotate, the rotation of the worm wheel 121 drives the worm 13 to rotate, the rotation of the worm 13 can drive the transmission gear 181 to rotate, and the transmission gear 181 drives the input end of the float generator 16 to rotate through the speed-increasing gear 182 and the output gear 183. S24, float generator 16 starts generating electricity.

[0037] One of the ocean current power generation components shall at least achieve the following steps: S31, when the spiral impeller 7 rotates in one direction with the ocean current, the spiral impeller 7 drives the transmission bevel gear to rotate. At this time, the transmission bevel gear drives the inner and outer gears 123 to rotate through the superimposed gear 151 and the transmission gear 152. S32, when the internal and external gears 123 rotate, they can drive the planetary helical gear 126 to rotate around the central gear 128, and at the same time, drive the central gear 128 to rotate. The rotation of the central gear 128 drives the main shaft 12 to rotate in one direction. S33, proceed to step S23; S34, float generator 16 starts generating electricity.

[0038] When this invention is placed in the ocean, the cylindrical housing 8 is moored at sea or on the seabed by anchor chains. The three sets of float upper shells 5 float on the sea surface and oscillate up and down under the force of waves, which drives the bidirectional generator 87 inside the cylindrical housing 8 to generate electricity. At the same time, the float upper shell 5 will have a height difference in the horizontal waves. During the formation of the height difference, the reciprocating rod 2, with the assistance of the swing pin 116, drives the two swing rods 111 and 112 to rotate around the ratchet 114 in opposite directions. The pawls 115 on the clockwise rotating swing rods 111 and 112 will slide relative to the teeth of the ratchet 114 and will not push the ratchet 114 to rotate. The pawls 115 on the counterclockwise rotating swing rods 111 and 112 will push the ratchet 114 to rotate counterclockwise. The rotation of the ratchet 114 will drive the main shaft 12 to rotate in one direction. When the helical impeller 7 rotates, it drives the transmission bevel gear to rotate. At this time, the transmission bevel gear drives the inner and outer gears 123 to rotate through the superimposed gear 151 and the transmission gear 152. The rotation of the inner and outer gears 123 drives the planetary helical gear 126 to rotate around the central gear 128, and at the same time, drives the central gear 128 to rotate. The rotation of the central gear 128 drives the main shaft 12 to rotate in one direction. The rotation of the main shaft 12 can transmit power to the transmission belt 14 through the worm gear 121, worm 13 and speed-increasing component 18. The rotation of the transmission belt 14 drives the input end of the generator 16 to rotate, thus generating electricity. In this way, wave energy and ocean current energy can be coupled to generate electricity.

[0039] During the power transmission process, the speed-up component 18 can increase the rotational speed of the generator 16 input terminal to 4 times the original speed through internal gear meshing, and the power generation efficiency is also increased by 4 times.

[0040] In this invention, seawater is filled into the ballast tank 81, which shifts the center of gravity of the cylindrical tank 8 to the ballast tank 81 and increases its draft. When the cylindrical tank 8 is placed on the sea surface and encounters wind and waves, its vertical sway is smaller, resulting in better wind resistance. At the same time, the upper shell 5 of the float moves more relative to the cylindrical tank 8, which is beneficial for the cylindrical tank power generation components to generate electricity.

[0041] When the upper shell 5 of the float is subjected to wave force and sways up and down with a small relative displacement in the swaying direction, the energy storage spring 611 effectively stretches or compresses, increasing its relative height displacement and amplifying the swaying displacement of the float power generation component, thus making the power generation efficiency of the float power generation component higher.

[0042] The coupling component can be referenced during operation. Figure 10 , Figure 10 From left to right, the components represent unidirectional input of ocean current energy and unidirectional input of wave energy. The coupling assembly operates in three modes: First, when there is no float and no vertical oscillation, only the unidirectional input of tidal energy drives the inner and outer gears 123 clockwise, which in turn transmits the energy to the central gear 128 via planetary gears for output. (See reference...) Figure 11 -a; Secondly, when the spiral impeller 7 is stationary, i.e., there is no ocean current energy, only the waves drive the upper shell 5 of the float to oscillate up and down as input, the planetary gear disk rotates, driving the planetary gears to rotate, which in turn drives the central gear 128 to rotate as output. (See reference...) Figure 11 -b; Thirdly, when there is both wave-driven float oscillation input and helical impeller 7 rotation input, planetary disk 127 and internal and external gears 123 rotate in one direction, thereby driving central gear 128 to rotate clockwise. (See reference...) Figure 11 -c.

[0043] The wave-current combined power generation platform of this invention can be flexibly deployed. By filling the ballast tank with seawater to increase the platform's draft, it can withstand strong winds of up to level 13 and waves as high as 3.8 meters, thus improving the platform's stability. Simultaneously, through the ingenious design of wave power generation components, ocean current power generation components, and coupling components, it achieves dual input and single output of wave energy and ocean current energy, enabling power generation by a single generator. Compared to the multiple generators or bidirectional generators used in traditional power generation platform floats, the single generator used in this invention is lower in cost and more reliable. More importantly, the wave-current combined power generation platform of this invention can simultaneously utilize wave current and ocean current energy for power generation, increasing the overall power generation efficiency of the platform by 49% and achieving higher energy utilization per unit area of ​​ocean.
