Therefore, no matter how the device moves under the action of waves, the DC generator 123 always generates electricity at the maximum rotational speed of the two terminal small ratchets 120; the DC generator 123 can always maintain a relatively high rotational speed to generate electricity, improving the utilization rate of wave energy; in addition, according to actual conditions, the heavy blocks on the left and right sides and the bottom of the combined transmission mechanism 5 and the terminal transmission mechanism 6 can be increased or decreased to adjust the buoyancy of the device of the present invention to adapt to the actual wave energy conditions and achieve the best wave energy utilization effect.;

[0065] As a second improvement, taking Figure 9 as an example, when the wave energy in the actual sea area is small, the combined method of changing the gear transmission ratio in Figure 9 can be adopted. The fourth largest gear 79 in the input second zone on the corresponding transmission shaft of the intermediate input mechanism 52 is replaced with an intermediate driving large pulley 126, and the first small gear 96 in the intermediate second zone on the corresponding transmission shaft of the intermediate output mechanism 56 is replaced with an intermediate driving small pulley 128. The transmission gears between the original fourth largest gear 79 in the input second zone and the first small gear 96 in the intermediate second zone are removed, changing the gear transmission ratio of the combined transmission mechanism 5. The intermediate synchronous belt 127 is used to connect the intermediate driving large pulley 126 and the intermediate driving small pulley 128. Correspondingly, the heavy blocks on the left and right sides and at the bottom of the two combined transmission mechanisms 5 and the terminal transmission mechanism 6 need to be adjusted to change the buoyancy of the device of the present invention to match the adjusted gear transmission ratio, and finally adapt to the wave conditions of the corresponding sea area to achieve the best wave energy conversion effect;

[0066] In addition, there are various forms of connection between the intermediate input mechanism 52 and the intermediate output mechanism 56 in the combined transmission mechanism 5. The input first zone in the intermediate input mechanism 52 can be directly connected to the intermediate second zone or the intermediate third zone of the intermediate output mechanism 56 by a synchronous belt; the input second zone in the intermediate input mechanism 52 can be directly connected to the intermediate first zone, the intermediate second zone or the intermediate third zone of the intermediate output mechanism 56 by a synchronous belt; the input third zone in the intermediate input mechanism 52 can be directly connected to the intermediate first zone or the intermediate second zone of the intermediate output mechanism 56 by a synchronous belt; similar to Figure 9 this, the gear transmission ratio of the combined transmission mechanism 5 can be flexibly changed, and the heavy blocks on the left and right sides and at the bottom of the two combined transmission mechanisms 5 and the terminal transmission mechanism 6 are correspondingly adjusted to change the buoyancy of the device of the present invention to match the adjusted gear transmission ratio and adapt to the corresponding sea wave conditions.

[0067] As a third improvement, as shown in Figure 10 , when the wave energy in the actual sea area is extremely large, the terminal transmission mechanism 6 can be replaced with a second terminal transmission mechanism 147; the second terminal transmission mechanism 147 includes a coupling 122, a DC generator 123, a motor support 124, a second terminal intermediate first transmission shaft 135, a second terminal intermediate first small pulley 136, a second terminal intermediate first large gear 137, a second terminal intermediate second transmission shaft 138, a second terminal intermediate second small gear 139, a second terminal intermediate second large gear 140, a second terminal first small gear 141, a second terminal first large gear 142, a second terminal first transmission shaft 143, a second terminal second small gear 144, a second terminal second transmission shaft 145, and a second terminal support 146;

[0068] As shown in Figure 11As shown, the second terminal bracket 146 and the terminal bracket 112 have basically the same structure. The difference is that the vertical plate of the second terminal bracket 146 for installing the transmission shaft becomes a complete vertical plate in the middle, which can cooperate with two small vertical plates on each of the left and right sides to install the transmission shaft. This enables two DC generators 123 to be installed on both sides of the second terminal bracket 146 simultaneously. The wave energy obtained at both ends of the middle buoy 9 can independently drive one DC generator 123 to generate electricity, and then the electric energy can be transmitted to the onshore power station or used for the storage battery.

[0069] The fourth largest pulley 111 in the middle three zones of the two output mechanisms 56 of the middle buoy 9 is connected to the first small pulley 136 in the middle of the second terminal through the middle output synchronous belt 149. The first small pulley 136 in the middle of the second terminal is connected to the first large gear 137 in the middle of the second terminal through the first transmission shaft 135 in the middle of the second terminal and rotates. The first large gear 137 in the middle of the second terminal drives the second small gear 139 in the middle of the second terminal to rotate. The second small gear 139 in the middle of the second terminal drives the second large gear 140 in the middle of the second terminal to rotate through the second transmission shaft 138 in the middle of the second terminal. The second large gear 140 in the middle of the second terminal drives the first small gear 141 of the second terminal to rotate. The first small gear 141 of the second terminal drives the first large gear 142 of the second terminal to rotate through the first transmission shaft 143 of the second terminal. The first large gear 142 of the second terminal drives the second small gear 144 of the second terminal to rotate. The second small gear 144 of the second terminal is connected to the coupling 122 through the second transmission shaft 145 of the second terminal to drive the DC generator 123 to generate electricity. The DC generator 123 is placed on the motor support 124, and the motor support 124 is connected to the second terminal bracket 146. The transmission connections on both sides of the second terminal transmission mechanism 147 are the same. Therefore, heavy blocks can be added to the left and right sides and the bottom of the two combined transmission mechanisms 5 of the middle buoy 9 and the second terminal transmission mechanism 147 to increase the buoyancy of the middle buoy assembly 3, make full use of the wave energy in the sea area where it is located, and the two DC generators 123 are respectively powered by both ends of the middle buoy assembly 3 to generate electricity, improving the utilization rate of wave energy.

[0070] As the fourth improvement, as Figure 12 shown, to obtain greater power generation, the buoy 9 of the end buoy assembly 2 and the middle buoy assembly 3 of the device of the present invention can be connected to the external buoy 129 to increase the buoyancy of the device of the present invention.

[0071] As Figure 12As shown, the external floating body 129 is a sealed cavity body that surrounds the left and right sides and the bottom of the floating drum 9; the top of both sides of the external floating body 129 is evenly distributed with external floating body threaded holes 130; the middle of the external floating body 129 is in contact with the bottom surface of the floating drum 9, and two rectangular sealing grooves 131 in the middle of the external floating body 129 are used for sealing; there is a rectangular cavity on the upper surface of the middle of the external floating body 129, and spaced grooves 132 are evenly distributed on both sides of the rectangular cavity for the rectangular spacer 133 to be inserted into the spaced grooves 132. The external load weight block 134 can be placed in two adjacent rectangular spacers 133. The corresponding number of external load weight blocks 134 can be placed according to the wave energy conditions of the sea area to increase the buoyancy of the device of the present invention, and the weight blocks on the left and right sides and the bottom of the two combined transmission mechanisms 5 and the terminal transmission mechanism 6 inside the floating drum 9 can be increased to make full use of wave energy and improve the wave energy capture ability; the external floating drum 129 can be connected in the first and third examples to further increase the buoyancy of the device of the present invention, and thus better improve the utilization rate of wave energy;

[0072] As the fifth improvement, as Figure 12 shown, according to the actual conditions of the sea area where it is located and the wave characteristics, the floating drums 9 can be connected side by side. The threaded holes on the upward bends on the adjacent sides of the two side-by-side floating drums 9 are connected and fixed with bolts. The number of side-by-side floating drums 9 can be selected according to the actual situation. In addition, the external floating drum 129 can be selected; and the terminal transmission mechanism 6 or the second terminal transmission mechanism 147 can be selected as needed; the side-by-side method of the floating drums 9 is adopted to obtain more wave energy and improve the wave energy capture ability.

Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
