[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0048] Example 1:

[0049] Please refer to Figures 1-4This embodiment of a wave power generation device based on a wind turbine tower comprises a tower body 1, a tower base 2, and a support truss 3. The tower body 1 houses the wind turbine, inverter, control cabinet, and other components, a prior art practice. The bottom of the support truss 3 is fixed to the seabed, providing support. The tower base 2 is fixedly connected to the tower body 1 and the support truss 3.

[0050] To facilitate the integration of the wave power generation device with the existing wind turbine tower and achieve cost savings, the support truss 3 is raised to expose the tower base 2 above the sea surface. The wave power generation device is placed inside the tower base 2. Furthermore, two upper and lower support plates 4 are fixedly connected to the tower base 2. A generator set 5 is fixedly mounted on the upper support plate 4, and a hydraulic oil tank 6 is fixedly mounted on the lower support plate 4.

[0051] Specifically, the generator set 5 includes a generator 51 and a hydraulic motor 52. The hydraulic motor 52 is connected to the generator 51, and the hydraulic pressure drives the generator 51 to generate electricity. The generator 51 is connected to the converter inside the tower body 1 via an electrical circuit, facilitating subsequent grid connection.

[0052] The hydraulic oil tank 6 comprises an outer tank 61 and an inner tank 62. The outer tank 61 is arranged in a ring shape outside the inner tank 62. Both the inner tank 62 and the outer tank 61 are connected to the hydraulic motor 52 via oil pipes 63. The accumulator 53 is connected to the oil pipe 63 between the outer tank 61 and the hydraulic motor 52, and the oil pipe 63 is equipped with a check valve.

[0053] In summary, the outer oil tank 61 is a high-pressure oil tank. The high-pressure oil enters the hydraulic motor 52 through the oil pipe 63. The hydraulic motor 52 drives the generator 51 to rotate and generate electricity, and then the low-pressure oil returns to the inner oil tank 62 through the pipeline.

[0054] Please refer to Figure 4 and Figure 5 In order to allow the oil in the external oil tank 61 to enter the hydraulic motor 52, a hydraulic cylinder 7 and a swing component 8 are provided below the hydraulic oil tank 6 (support plate 4).

[0055] Specifically, the swing component 8 includes a swing rod 81 and a swing ball 82 ( Figure 7 (marked in the middle), the upper end of the swing rod 81 is connected to the bottom of the lower support plate 4 via a spherical hinge structure, and the lower end of the swing rod 81 extends out of the tower base 2. The swing ball 82 is mounted on the swing rod 81. The swing ball 82 is made of plastic and is located below the tower base 2, floating on the sea surface. A connecting seat 83 is also fixed to the swing rod 81.

[0056] Hydraulic cylinder 7 is equipped with a fixed piston plate 71 and piston rod 72. One end of piston rod 72 extends out of hydraulic cylinder 7, and a movable seal is provided between piston rod 72 and hydraulic cylinder 7. Piston plate 71 divides the interior of hydraulic cylinder 7 into two chambers. These chambers are connected to an oil inlet pipe 73 and an oil outlet pipe 74, respectively. Both oil inlet pipes 73 and 74 are equipped with check valves.

[0057] Please refer to Figure 4 and Figure 5 For the convenience of explanation, the first oil inlet pipe 731 and the first oil outlet pipe 741 are defined as those away from the piston rod 72 , and the second oil inlet pipe 732 and the second oil outlet pipe 742 are defined as those close to the piston rod 72 .

[0058] It should also be noted that the upper ends of the first oil inlet pipe 731 and the second oil inlet pipe 732 both pass through the lower support plate 4 and are connected to the inner oil tank 62, while the upper ends of the first oil outlet pipe 741 and the second oil outlet pipe 742 both pass through the support plate 4 and are connected to the outer oil tank 61.

[0059] If the control piston plate 71 is pressed Figure 5 If the oil moves in the direction of the middle arrow, the pressure in the upper cavity increases, and the high-pressure oil in the cavity enters the outer oil tank 61 through the first oil outlet pipe 741. At the same time, the pressure in the lower cavity decreases, and the second oil inlet pipe 732 will absorb the low-pressure oil in the inner oil tank 62 into the cavity. Figure 5 The middle piston plate 71 moves in the opposite direction of the arrow shown in the figure, the second oil outlet pipe 742 will input the high-pressure oil into the outer oil tank 61, and the first oil inlet pipe 731 will absorb the low-pressure oil in the inner oil tank 62 into the hydraulic cylinder 7.

[0060] In this embodiment, six hydraulic cylinders 7 are provided, distributed around the swing arm 81. One end of each hydraulic cylinder 7 is connected to the inner wall of the tower base 2 via a universal joint. The end of the piston rod 72 extending from the hydraulic cylinder 7 is movably connected to the connecting seat 83 on the swing arm 81 via a spherical hinge structure.

[0061] In summary, the upper end of the swing rod 81 is connected to the support plate 4 through a spherical hinge structure, and the swing ball 82 floats on the sea surface. When waves pass by, the swing ball 82 and the swing rod 81 swing together around the connection point at the upper end of the swing rod 81.

[0062] When the swing arm 81 moves, the piston plate 71 is driven to move via the piston rod 72, and high-pressure oil is delivered to the outer oil tank 61. The hydraulic motor 52 then drives the generator 51 to rotate and generate electricity.

[0063] Because there are six groups of hydraulic cylinders 7 around the swing rod 81, and as described above, the piston plate 71 is Figure 5The arrow shown in the figure can move in both positive and negative directions to inject high-pressure oil into the outer oil tank 61. Therefore, no matter the direction of the waves, the hydraulic motor 52 can drive the generator 51 to rotate.

[0064] Please refer to Figure 6 When the waves reach their crests, the swing ball 82 will swing. When the waves reach their troughs, the swing rod 81 and the swing ball 82 will reset under the action of gravity. In actual use, a spring damper 9 is also provided. Installed in the same direction as the hydraulic cylinder 7, one end of the spring damper 9 is connected to the inner wall of the tower base 2 via a universal joint, and the other end is movably connected to the connecting seat 83 on the swing rod 81 via a spherical hinge structure. When the swing rod 81 swings, the damper 9 stabilizes the swing process, reducing high-frequency vibrations and shocks. It also facilitates the return of the swing axis to a vertical state, making it easier to cope with the next wave crest.

[0065] Example 2:

[0066] Please refer to Figure 7-10 Based on the first embodiment, this embodiment has the following further improvements:

[0067] When extreme weather occurs and the wind and waves are large, the impact on the swing ball 82, the swing rod 81 and the internal hydraulic cylinder 7 will increase. In order to avoid the swing rod 81 swinging too much in extreme weather and causing it to break, a locking component 11 is also provided.

[0068] Specifically, first, a fixing seat 10 is fixedly connected to the bottom of the tower base 2 , and a mounting hole 101 for the swing rod 81 to pass through is opened in the middle of the fixing seat 10 .

[0069] The locking component 11 includes a limiting block 112 , a baffle 115 and a locking cylinder 117 .

[0070] First, to install the limit block 112, a limit hole 111 is opened inside the fixing base 10 and on the inner wall of the mounting hole 101. The limit block 112 is movably installed in the limit hole 111. A compression spring 113 is also provided on the limit block 112 and the inner wall of the limit hole 111. The compression spring 113 can push one end of the limit block 112 out of the mounting hole 101.

[0071] The function of the baffle 115 is to prevent the compression spring 113 from pushing the limit block 112 out of the limit hole 111 when the swing rod 81 is working. Therefore, a baffle mounting groove 114 is provided on the fixing seat 10 and outside the mounting hole 101. Figure 8 The above-mentioned limiting hole 111 is arranged horizontally, and the baffle installation groove 114 is opened vertically, and the two are connected. The baffle 115 is movably installed in the baffle 115 limiting groove, and the baffle 115 can move up and down in the baffle 115 limiting groove.

[0072] Please refer to Figure 9 and Figure 10 The baffle 115 is cylindrical in shape, with an inward bend at the upper end and an outward bend at the lower end. The outward bend at the lower end cooperates with the baffle mounting groove 114 to play a limiting role. A hole is opened on the side wall of the baffle 115 for the time limit block 112 to pass through.

[0073] In the initial state, when the baffle 115 is at its lowest point, the baffle 115 blocks the limit block 112, preventing the limit block 112 from moving. If the baffle 115 moves upward and the hole on the baffle 115 is at the same height as the limit hole 111, the limit block 112 can pass through the baffle 115 and extend out of the limit hole 111.

[0074] The locking cylinder 117 is mounted on the swing rod 81, and the lower end of the locking cylinder 117 is fixedly connected to the swing ball 82. The side wall of the locking cylinder 117 is also provided with a locking hole 118 that is compatible with the stop block 112. When encountering large waves, the sea level will rise, and the swing ball 82 and the locking cylinder 117 will move upward along the swing rod 81. When the locking cylinder 117 passes through the mounting hole 101 in the fixed base 10, it will push the baffle 115 upward. At this time, the stop block 112, under the action of the compression spring 113, extends into the locking hole 118. At this time, the swing ball 82 cannot descend further and remains at the bottom of the fixed base 10.

[0075] Therefore, when encountering larger waves, the seawater drives the swing ball 82 to rise, so that the swing ball 82 is fixed to the bottom of the tower base 2. Avoid large winds and waves to damage the swing component 8.

[0076] In order to prevent the stopper 112 from being unable to extend due to the misalignment between the hole on the stopper 115 and the stopper hole 111 after the stopper 115 rotates, a vertical oblong hole ( Figure 10 At the same time, a screw is installed in the baffle mounting groove 114 so that the screw passes through the oblong hole on the baffle 115 to ensure that the baffle 115 can only move up and down and cannot rotate.

[0077] Furthermore, to reset the stopper 112 after strong winds and waves, allowing the swinging ball 82 to continue operating, an electromagnet 116 is provided. This electromagnet 116 is embedded within the fixing base 10 and located at one end of the stopper hole 111. The stopper 112 is made of iron. When electromagnet 116 is energized and generates magnetism, it attracts the stopper 112 and retracts it back into the stopper hole 111. At this point, the swinging ball 82 and baffle 115 return to their original positions under the action of gravity, allowing power generation to continue.

[0078] The implementation principle and beneficial effects of a wave power generation device based on a wind power tower in this application are as follows:

[0079] (1): First, combine the wave power generation device with the existing wind power tower to form a hybrid power generation system, further improve resource utilization efficiency, reduce construction and operation and maintenance costs, and promote the comprehensive development of marine energy.

[0080] (2): When the wave power generation equipment is working, the upper end of the swing rod 81 is connected to the support plate 4 through a spherical hinge structure, and the swing ball 82 floats on the sea surface. When a wave passes by, it will push the swing ball 82 to move, and the swing ball 82 and the swing rod 81 will swing around the connection point at the upper end of the swing rod 81. The piston plate 71 will move through the drive of the connecting seat 83 and the piston rod 72, and the high-pressure oil will be transported to the outer oil tank 61 and the hydraulic motor 52, thereby driving the generator 51 to rotate and generate electricity, and the low-pressure oil will return to the inner oil tank 62, forming a cycle. Finally, the electricity generated by the hydraulic generator set 5 and the electricity generated by wind power generation are connected to the grid and transmitted.

[0081] In the above-mentioned first embodiment, six groups of hydraulic cylinders 7 are arranged around the swing rod 81, so no matter from which direction the waves rush towards the swing ball 82, power generation can be performed, thereby improving power generation efficiency.

[0082] (3): When extreme weather conditions occur, resulting in strong winds and waves at sea, the rising sea level drives the swing ball 82 upward. When the locking cylinder 117 passes through the mounting hole 101 on the fixed base 10, it will push the baffle 115 upward. At this time, the limit block 112 extends into the locking hole 118 under the action of the compression spring 113. At this time, the swing ball 82 cannot descend any further and remains at the bottom of the fixed base 10. It cannot continue to swing, thus preventing the swing rod 81 from directly breaking in extreme weather conditions, or causing a large impact on other structures in the tower base 2, thereby damaging the equipment.

[0083] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
