Description

Technical Field

[0001] The present invention relates to the technical field of offshore power generation, and in particular to an offshore wind energy and wave energy coordinated combined power generation device. Background Art

[0002] With the advancement of the global energy structure transformation, the development of marine renewable energy has become a key research direction in various countries. Among them, offshore wind energy and wave energy have attracted much attention due to their abundant resources and strong sustainability. Both are important renewable energy sources. Wind turbines capture wind energy and convert it into electricity, while wave power generation devices use the kinetic energy of waves to generate electricity.

[0003] Traditional wave energy generation methods obtain electricity by converting energy through the movement of floats in the vertical direction of the waves. The conversion process involves a large number of energy conversion components such as piston rods, hydraulic cylinders, and accumulators. The conversion of wave energy into electricity involves multiple stages, resulting in low conversion efficiency. There is currently a published patent, patent number: CN202310638331.7, patent name: Wave Energy Power Generation Device, Offshore Wind Turbine Combined Power Generation System and Method. This patent improves the energy conversion method of wave energy and can directly convert wave energy into electricity without the need for secondary energy conversion such as hydraulic energy and air pressure energy, thus solving traditional problems. However, offshore wind energy is also a very important power generation resource. Under the same natural conditions, the power generation efficiency of wind energy is greater than that of wave energy. This patent makes it difficult to effectively combine the two power generation methods and can only compare power to supplement power generation. Therefore, this patent still has shortcomings and needs to be improved in terms of complementarity between the two power generation methods and maintaining the stability of each power generation.

[0006] It also includes two groups of cooperative power generation components, two groups of wind protection components and two groups of wave protection components. The two groups of cooperative power generation components are arranged in a protective shell to drive the two cooperative power generation panels to generate airflow when the two spiral components move vertically relative to the floating base.

[0007] Optionally, the wave power generation device includes a power generation box and a transmission submarine cable, and the power generation box is connected to the power storage part of the generator through the transmission submarine cable.

[0008] The cam is connected to the drive shaft of the said rotary shaft by the said rotary shaft, and the cam is connected to the said rotary shaft by the said rotary shaft. The said rotary shaft has two ends connected to the said rotary shaft and the said rotary shaft has a bottom end and a bottom end. The cam is connected to the said rotary shaft by the said rotary shaft.

[0009] Optionally, the wind protection component includes a transmission rod, which is fixedly connected to the surface of the adaptation plate. The transmission rod passes through the fixed block and the piston cylinder in sequence, and the protective cylinder is fixedly connected to the top end of the transmission rod.

[0010] Optionally, the wave protection component includes two slides, the two ends of the slides are fixedly connected to the surface of the fixed block and the inner wall of the protective shell respectively, the inner walls of the two slides are slidably connected with sliders, the inner walls of the two sliders are rotatably connected to the shaft wall of the rotating shaft, the two ends of the rotating shaft are rotatably connected with hinged rods, and the ends of the two hinged rods are hinged to the top surface of the adaptation plate.

[0011] Optionally, two waterproof cylinders are fixedly connected to the top surface of the floating base, the output ends of the two waterproof cylinders are fixedly connected to the bottom surface of the adaptive plate, and the side wall of the floating base is provided with a sensing device.

[0012] Optionally, a ventilation groove is provided on the bottom surface of the protective cylinder, and the size of the ventilation groove is adapted to the size of the impeller.

[0013] Optionally, the two collaborative power generation panels are rotationally symmetrically arranged in a top-down perspective, and the three groups of air outlets on the collaborative power generation panels are vertically equidistantly arranged. The rod wall of the fixed rod is fixedly connected with six clamps, and the six clamps are divided into two groups and are respectively clamped to the tube walls of the two one-way tubes.

[0014] The optional anchoring component includes four anchoring seats, which are all fixedly installed on the bottom surface of the floating base. Anchoring cables are provided on the four anchoring seats, and anchoring nails are provided at the ends of the four anchoring cables.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention, through the coordination of structures such as the deflection rod, the transmission plate and the push rod, can continuously discharge airflow from the cooperative power generation plate when the waves rise and fall, thereby assisting the impeller to rotate and generate electricity. Compared with traditional methods, the present application fully utilizes the horizontal movement and vertical undulation of sea waves and performs power generation conversion accordingly, which naturally has a higher utilization rate and better power generation effect.

[0017] Second, the present invention cooperates with the protective tube, transmission rod, and adaptive plate. In case of strong winds, the wind speed will increase significantly due to the lack of any obstructions on the sea surface. To prevent the generator power from changing too much and affecting the long-term safe use of the power generation assembly, the adaptive plate can be moved vertically upward to push the protective tube to move vertically upward until the protective tube completely covers the impeller. In this way, the protective tube can cover the impeller in weather with excessive wind speed, thereby preventing the impeller from rotating too fast and affecting the long-term safe use of the generator.

[0018] At the same time, while the protective tube is shielding the impeller, the waves on the sea surface are still rising and falling, that is, the two cooperative power generation panels are still continuously ejecting airflow, that is, the impeller can still rotate and generate electricity at a relatively slow speed compared to natural conditions, which does not affect the power generation work, and also enables the wind energy generation to be controlled within a fixed frequency range.

[0019] 3. The present invention cooperates with structures such as a slider, a rotating shaft and a hinged rod, so that in windy weather conditions, the deflection rod is pushed, so that the deflection rod pushes the spiral assembly and the power generation box on it to move away from the floating base, thereby increasing the distance between the spiral assembly and the floating base, ensuring that the wave energy power generation effect of the spiral assembly itself is not reduced, that is, ensuring its own wave energy power generation effect.

[0020] Fourth, the present invention combines wave energy and wind energy to generate electricity in a coordinated manner, thereby fully utilizing natural conditions. At the same time, the defects of the two are complementary, and the practical effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For example 1, please refer to Figures 1 to 11 The present invention provides an offshore wind and wave energy coordinated combined power generation device, comprising a floating base 1, the bottom surface of the floating base 1 is provided with an anchoring component, the top surface of the floating base 1 is fixedly connected to a fixed rod 2, a generator 3 is provided in the fixed rod 2, and wave power generation devices are provided on both sides of the floating base 1. The wave power generation device includes a spiral component 4, a generator box 12 and a transmission cable 13. The generator box 12 is connected to the power storage part of the generator 3 through the transmission cable 13. The rod wall of the fixed rod 2 is fixedly connected to a fixed block 5 and a piston cylinder 6, and the rod wall of the fixed rod 2 is slidably connected to an adaptation plate 7. The top surface of the floating base 1 is fixedly connected to a protective shell 8, the power generation shaft of the generator 3 is fixedly connected to an impeller 9, the impeller 9 is rotatably connected to the end of the fixed rod 2, a protective cylinder 10 is provided below the impeller, and coordinated power generation plates 11 are provided on both sides of the impeller 9.

[0035] It also includes two groups of cooperative power generation components, two groups of wind protection components and one group of wave protection components. The two groups of cooperative power generation components are arranged in the protective shell 8, so that when the two spiral components 4 move vertically relative to the floating base 1, they respectively drive the two cooperative power generation panels 11 to generate airflow, and pass through the two groups of wind protection components to make the protective tube 10 displace vertically. Through the two groups of wave protection components, when the protective tube 10 moves upward, the spiral component 4 is displaced away from the floating base 1.

[0036] The cooperative power generation component includes a deflection rod 14, which is rotatably connected to the connecting shaft of the spiral assembly 4. The rod wall of the deflection rod 14 is fixedly connected to the rotating shaft 15. The shaft wall of the rotating shaft 15 is fixedly connected to two transmission disks 16. The fixed block 5 and the surface of the protective shell 8 are slidably connected to a push rod 17. The rod wall of the push rod 17 is provided with a displacement groove 32. The opposite sides of the two transmission disks 16 are rotatably connected to a push shaft 18. The shaft wall of the push shaft 18 is slidably connected to the groove wall of the displacement groove 32. The top surface of the rod 17 is fixedly connected to the piston rod 19, the rod wall of the piston rod 19 is slidably connected to the inner wall of the protective shell 8, the end of the piston rod 19 is fixedly connected to the piston plate 20, the piston plate 20 is slidably connected to the inner wall of the piston cylinder 6, the surface of the piston cylinder 6 is fixedly connected to a one-way tube 1 21 and a one-way tube 2 22, three groups of air outlets are provided on the inner wall of the cooperative power generation plate 11, the bottom surface of the cooperative power generation plate 11 is fixedly connected to an air transfer plate 23, and the air transfer plate 23 is fixedly connected to the end of the one-way tube 2 22.

[0037] The anchoring component includes four anchoring seats 29 , which are all fixedly mounted on the bottom surface of the floating base 1 . An anchoring cable 30 is provided on each of the four anchoring seats 29 , and an anchoring nail 31 is provided at the end of each of the four anchoring cables 30 .

[0038] In this embodiment: during the initial installation of the device, the anchoring nail 31 cooperates with the anchoring cable 30 to make the floating base 1 float on the sea surface. When the sea breeze blows, it will drive the impeller 9 to rotate, and the rotation of the impeller 9 enables the generator 3 to generate wind power. When waves come, the waves will drive the spiral assembly 4 to rotate. Through the rotation of the spiral assembly 4, the generator box 12 generates electricity, and the generated current is transmitted to the generator box 12 through the transmission cable 13, so that the current generated by wind power generation and the current generated by wave power generation are stored together. In this process, the power generation principles of wind energy and wave energy can be regarded as existing technologies and will not be described in detail here. Since the waves do not only drive the spiral assembly 4 to rotate, the waves also have the characteristics of undulation, so they will also drive the spiral assembly 4 to undulate vertically. During the undulating process, since the floating base 1 is limited by the anchoring cable 30, the floating base 1 can be regarded as a static state without displacement. Therefore, when the spiral assembly 4 undulates vertically, The deflection rod 14 is deflected, and the deflection of the deflection rod 14 causes the shaft 15 to rotate. The rotation of the shaft 15 drives the two transmission plates 16 to deflect, so that the push shaft 18 is displaced in an arc trajectory with the shaft 15 as the axis through the deflection of the two transmission plates 16. The arc trajectory displacement of the push shaft 18 pushes the inner wall of the displacement groove 32, so that the push rod 17 is displaced in the vertical direction. The transmission of the push rod 17 can make the piston rod 19 displaced in the vertical direction, thereby making The piston plate 20 is moved vertically back and forth in the piston cylinder 6. When the piston plate 20 moves vertically downward, the one-way tube 1 21 is opened, and the external air flow is drawn into the piston cylinder 20 through the one-way tube 1 21. When the piston plate 20 moves vertically upward, the one-way tube 2 22 is opened, and the gas in the piston cylinder 20 is pushed out through the one-way tube 22. At this time, the air flow passes through the one-way tube 22 and flows into the air transfer plate 23, and then flows from the air transfer plate 23 to the cooperative power generation plate 11, and is discharged from the air outlet of the cooperative power generation plate 11.

[0039] In the above manner, air flow can be continuously discharged from the cooperative power generation plate 11 when the waves rise and fall, thereby assisting the impeller 9 to rotate and generate electricity. This fully utilizes the horizontal movement power generation and vertical fluctuation power generation of sea surface waves, making natural utilization higher and the power generation effect better.

[0040] Example 2, based on the above example:

[0041] See also Figures 1 to 11The wind protection component includes a transmission rod 24, which is fixedly connected to the surface of the adaptation plate 7. The transmission rod 24 passes through the fixed block 5 and the piston cylinder 6 in sequence. The protective cylinder 10 is fixedly connected to the top of the transmission rod 24. Two waterproof cylinders 28 are fixedly connected to the top surface of the floating base 1. The output ends of the two waterproof cylinders 28 are fixedly connected to the bottom surface of the adaptation plate 7. The side wall of the floating base 1 is provided with an induction device. The bottom surface of the protective cylinder 10 is provided with a ventilation groove. The size of the ventilation groove is adapted to the size of the impeller 9. The two cooperative power generation panels 11 are rotationally symmetrically arranged in a top view, and the three groups of air outlets on the cooperative power generation panel 11 are arranged vertically equidistantly. Six clamping seats 33 are fixedly connected to the rod wall of the fixed rod 2. The six clamping seats 33 are divided into two groups and are respectively clamped to the pipe walls of the two one-way pipes 22.

[0042] In this embodiment: In case of strong winds, since there are no obstructions on the sea surface, the wind speed will increase significantly. In order to avoid excessive differences in the power changes of the generator 3, which will affect the long-term use safety of the power generation components, the changes in the surrounding environment can be sensed by the sensing device. Then, the two waterproof cylinders 28 can be started. The two waterproof cylinders 28 are driven to make the adaptation plate 7 move vertically upward. The vertical movement of the adaptation plate 7 causes the transmission rod 24 to move vertically upward. In the process of the vertical movement of the transmission rod 24, it will slide along the inner wall of the fixed block 5 and the piston cylinder 6. The vertical movement of the transmission rod 24 can push the protective cylinder 10 to move vertically upward until the protective cylinder 10 completely blocks the impeller 9, and then the driving of the two waterproof cylinders 28 is stopped.

[0043] At the same time, by opening the ventilation groove, when the impeller 9 is blocked, no negative pressure area will be formed, which will make it difficult for the impeller 9 to rotate. At the same time, by setting the six sockets 33, the one-way tube 22 is not easy to fall off, ensuring stability for long-term use.

[0044] By adopting this method, when the wind speed is too high, the impeller 9 can be shielded by the protective tube 10, thereby preventing the impeller 9 from rotating too fast and affecting the long-term use safety of the generator 3. At the same time, while the protective tube 10 is keeping the impeller 9 shielded, the sea waves are still rising and falling, that is, the two cooperative power generation panels 11 are still continuously ejecting airflow, that is, the impeller 9 can still rotate at a slower speed than under natural conditions to generate electricity, which does not affect the progress of power generation, and also enables wind energy generation to be controlled within a fixed frequency range.

[0045] Example 3, based on the above example:

[0046] See also Figures 1 to 9The wave protection component includes two slides 25, the two ends of which are fixedly connected to the surface of the fixed block 5 and the inner wall of the protective shell 8 respectively. The inner walls of the two slides 25 are slidably connected with sliders 26, and the inner walls of the two sliders 26 are rotatably connected to the shaft wall of the rotating shaft 15. The two ends of the rotating shaft 15 are rotatably connected with hinged rods 27, and the ends of the two hinged rods 27 are hinged to the top surface of the adaptation plate 7.

[0047] In this embodiment, while the adaptation plate 7 is moving vertically upward, the two hinged rods 27 will also be pushed to move, so that the two sliders 26 slide along the inner walls of the two slide seats 25 respectively. The displacement of the two sliders 26 can cause the two rotating shafts 15 to move. Taking a single rotating shaft 15 as an example, the lateral movement of the rotating shaft 15 can cause the transmission plate 16 connected thereto to move synchronously. During this displacement process, the push shaft 18 will slide along the groove wall of the displacement groove 32. Due to the provision of the displacement groove 32, the lateral movement of the rotating shaft 15 will not affect the vertical transmission of the push shaft 18 in the above process. During the lateral movement of the rotating shaft 15, the deflection rod 14 will be pushed, so that the deflection rod 14 pushes the spiral assembly 4 and the power generation box thereon to move together in a direction away from the floating base 1, thereby increasing the distance between the spiral assembly 4 and the floating base 1.

[0048] Taking into account that the lateral movement of seawater will also increase under strong wind conditions, and when there are large waves, when the flow of seawater is pushed from the spiral assembly 4, the seawater will encounter the floating base 1 and produce backflow, that is, at this time, a small amount of seawater backflow will be generated between the floating base 1 and the spiral assembly 4. This phenomenon will be more obvious if other meteorological components need to be installed on the floating base 1 and the area of ​​the floating base 1 is increased. That is, as the wave potential energy increases, the rotational power generation of the spiral assembly 4 will not increase proportionally. Therefore, by controlling the spiral assembly 4 away from the floating base 1, the wave energy power generation effect of the spiral assembly 4 itself is ensured.

[0049] Working principle: When the offshore wind and wave energy synergistic combined power generation device is in use, the anchor nail 31 cooperates with the anchor cable 30 to make the floating base 1 float on the sea surface. When the sea breeze blows, it will drive the impeller 9 to rotate, and the rotation of the impeller 9 enables the generator 3 to generate wind power. When waves come, the waves will drive the spiral assembly 4 to rotate. Through the rotation of the spiral assembly 4, the generator box 12 generates electricity and the generated current is transmitted to the generator box 12 through the transmission cable 13, so that the current generated by wind power generation and the current generated by wave power generation are stored together. Since the waves not only drive the spiral assembly 4 to rotate, but also have the characteristics of undulation, they will also drive the spiral assembly 4 to undulate vertically. During the undulation process, since the floating base 1 is limited by the anchor cable 30, the floating base 1 can be regarded as a static state without displacement. Therefore, when the spiral assembly 4 undulates vertically, it will cause the deflection rod 14 to deflect. Through the deflection transmission of the deflection rod 14, the rotating shaft 15 will rotate. Thereby, the two transmission plates 16 are driven to deflect, and the deflection of the two transmission plates 16 causes the push shaft 18 to move in an arc trajectory with the rotating shaft 15 as the axis. The arc trajectory displacement of the push shaft 18 pushes the inner wall of the displacement groove 32, causing the push rod 17 to move vertically, thereby causing the piston plate 20 to move back and forth vertically in the piston cylinder 6. When the piston plate 20 moves vertically downward, the one-way tube 1 21 is opened, and the external air flow is drawn into the piston cylinder 20 through the one-way tube 1 21. When the piston plate 20 moves vertically upward, At this time, the one-way pipe 22 is opened, and the gas in the piston cylinder 20 is pushed out through the one-way pipe 22. At this time, the airflow passes through the one-way pipe 22 and flows into the air transmission plate 23. Then, it flows from the air transmission plate 23 into the cooperative power generation plate 11 and is discharged from the air outlet of the cooperative power generation plate 11. In this way, when the waves rise and fall, the airflow can be continuously discharged from the cooperative power generation plate 11, thereby causing the auxiliary impeller 9 to rotate and generate electricity. This fully utilizes the horizontal movement of the sea waves to generate electricity and the vertical fluctuation of the waves to generate electricity, making the natural utilization rate higher and the power generation effect better.

[0050] In case of strong winds, the wind speed will increase significantly due to the lack of shelter on the sea surface. In order to avoid excessive power variation of the generator 3, which may affect the long-term use safety of the power generation components, the sensor device may sense the change in the surrounding environment, and then the two waterproof cylinders 28 may be activated. The two waterproof cylinders 28 are driven to make the adaptation plate 7 move vertically upward. The vertical movement of the adaptation plate 7 causes the transmission rod 24 to move vertically upward. In the process of the transmission rod 24 moving vertically upward, it will slide along the inner wall of the fixed block 5 and the piston cylinder 6. The vertical movement of the transmission rod 24 can push the protective cylinder 10 to move upward. Move vertically upward until the protective cylinder 10 completely blocks the impeller 9, and then stop driving the two waterproof cylinders 28. In this way, when the wind speed is too high, the protective cylinder 10 blocks the impeller 9, thereby preventing the impeller 9 from rotating too fast and affecting the long-term use safety of the generator 3. At the same time, while the protective cylinder 10 blocks the impeller 9, the sea waves are still rising and falling, that is, the two cooperative power generation panels 11 are still continuously ejecting air, that is, the impeller 9 can still rotate and generate electricity at a relatively slow speed under natural conditions, which does not affect the power generation work, and also enables the wind energy generation to be controlled within a fixed frequency range.

[0051] During the vertical upward movement of the adaptation plate 7, the two hinged rods 27 will also be pushed to move, so that the deflection rod 14 pushes the spiral assembly 4 and the power generation box thereon to move away from the floating base 1, thereby increasing the distance between the spiral assembly 4 and the floating base 1, thereby ensuring the wave energy power generation effect of the spiral assembly 4 itself.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
