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 for various countries. Among them, offshore wind energy and wave energy have attracted much attention due to their rich resources and strong sustainability. Both are important renewable energy sources. Wind turbines capture wind energy and convert it into electrical energy, and wave energy generation devices use the kinetic energy of waves to generate electricity.

[0003] The traditional wave energy generation method obtains electricity by converting energy through the movement of the float in the vertical direction of the waves. The conversion process involves a lot of energy conversion components such as piston rods, hydraulic cylinders and accumulators. There are multiple conversion processes between wave energy and electrical energy, and the conversion efficiency is low. There is now a public patent, patent number: CN202310638331.7, patent name: wave energy power generation device, offshore wind turbine combined power generation system and method. The patent improves the energy conversion method of wave energy, and can directly convert wave energy into electrical energy without the need for secondary energy conversion such as hydraulic energy and air pressure energy, which solves the traditional problem.

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

[0016] 1. The present invention can continuously discharge airflow from the cooperative power generation plate when the waves rise and fall through the coordination of structures such as the deflection rod, the transmission plate and the push rod, thereby assisting the impeller to rotate and generate electricity.

[0017] Second, the present invention cooperates with the structures such as the protective tube, the transmission rod and the adaptation plate. In case of strong winds, the wind speed will increase significantly because there is no shielding on the sea surface.

In this way, the impeller can be blocked by the protective tube in weather with excessive wind speed, thereby preventing the impeller from rotating too fast and affecting the long-term use safety of the generator.

[0018] At the same time, while the protective tube is keeping the impeller shielded, the sea waves 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 at a slower speed than under natural conditions to generate electricity, 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 thereon to move away from the floating base, so that the distance between the spiral assembly and the floating base is increased, 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 making full use of natural conditions. At the same time, the defects of the two are complementary, and the practical effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] For example, see Figures 1 to 11 The present invention provides an offshore wind energy 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 with a fixing rod 2, a generator 3 is arranged in the fixing rod 2, wave power generation devices are arranged on both sides of the floating base 1, the wave power generation device comprises a spiral component 4, a power generation box 12 and a transmission submarine cable 13, the power generation box 12 is connected to the power storage part of the generator 3 through the transmission submarine cable 13, the rod wall of the fixing rod 2 is fixedly connected with a fixing block 5 and a piston cylinder 6, the rod wall of the fixing rod 2 is slidably connected with an adaption plate 7, the top surface of the floating base 1 is fixedly connected with a protective shell 8, the power generation shaft of the generator 3 is fixedly connected with an impeller 9, the impeller 9 is rotatably connected to the end of the fixing rod 2, a protective cylinder 10 is arranged below the impeller, and coordinated power generation plates 11 are arranged 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 the two groups of wind protection components are used to make the protective tube 10 move vertically, and the two groups of wave protection components are used to make the spiral component 4 move away from the floating base 1 when the protective tube 10 moves upward.

[0036] The cooperative power generation component includes a deflection rod 14, which is rotatably connected to the connecting shaft of the spiral assembly 4, and the rod wall of the deflection rod 14 is fixedly connected to a rotating shaft 15, and the shaft wall of the rotating shaft 15 is fixedly connected to two transmission disks 16, and the fixed block 5 and the surface of the protective shell 8 are slidably connected to a push rod 17, and the rod wall of the push rod 17 is provided with a displacement groove 32, and the opposite sides of the two transmission disks 16 are rotatably connected to a push shaft 18, and the shaft wall of the push shaft 18 is slidably connected to the groove wall of the displacement groove 32, and 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 a 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 a 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 opened 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 , and anchoring cables 30 are disposed on the four anchoring seats 29 , and anchoring nails 31 are disposed at the ends of the four anchoring cables 30 .

[0038] In this embodiment: during the initial installation of the device, the floating base 1 floats on the sea surface through the cooperation of the anchor nail 31 and the anchor cable 30. 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 submarine 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 prior art and will not be repeated here. Since the waves do not only drive the spiral assembly 4 to rotate, but also have the characteristics of ups and downs, they will also drive the spiral assembly 4 to rise and fall vertically. During the ups and downs, 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 rises and falls vertically, The deflection rod 14 is deflected, and the deflection of the deflection rod 14 causes the rotating shaft 15 to rotate, and the rotation of the rotating shaft 15 drives the two transmission plates 16 to deflect, so that the push shaft 18 is displaced in an arc trajectory with the rotating shaft 15 as the axis through the deflection of the two transmission plates 16, and 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, and the transmission of the push rod 17 can make the piston rod 19 displaced in the vertical direction, so that The piston plate 20 is vertically moved back and forth in the piston cylinder 6. When the piston plate 20 moves vertically downward, the one-way tube 21 is opened, and the external airflow is drawn into the piston cylinder 20 through the one-way tube 21. When the piston plate 20 moves vertically upward, the one-way tube 22 is opened, and the gas in the piston cylinder 20 is pushed out through the one-way tube 22. At this time, the airflow passes through the one-way tube 22, 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] Through the above method, when the waves rise and fall, the air flow can be continuously discharged from the cooperative power generation plate 11, thereby assisting the impeller 9 to rotate and generate electricity. This makes full use of the horizontal movement power generation and vertical fluctuation power generation of sea surface waves, making the natural utilization rate stronger and the power generation effect better.

[0040] Embodiment 2, based on the above embodiment:

[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 a sensing 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 panels 11 are arranged vertically equidistantly. The rod wall of the fixed rod 2 is fixedly connected with six clamping seats 33. 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, and then the two waterproof cylinders 28 can be started. Through the driving of the two waterproof cylinders 28, the adaptation plate 7 is moved vertically upward. Through the vertical movement of the adaptation plate 7, the transmission rod 24 is moved 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. Through the vertical movement of the transmission rod 24, the protective cylinder 10 can be pushed 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 the stability of 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, so as to prevent the impeller 9 from rotating too fast and affecting the long-term safe use of the generator 3. At the same time, while the protective tube 10 is shielding the impeller 9, 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 power generation work, and also makes the wind energy generation controllable within a fixed frequency range.

[0045] Embodiment 3, based on the above embodiment:

[0046] See also Figures 1 to 9The wave protection component includes two slides 25, the two ends of the two slides 25 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, the inner walls of the two sliders 26 are rotatably connected to the shaft wall of the rotating shaft 15, and 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: during the vertical upward movement of the adaptation plate 7, the two hinged rods 27 will also be pushed to be displaced, so that the two sliders 26 slide along the inner walls of the two slide seats 25 respectively. The two rotating shafts 15 can be displaced by the displacement of the two sliders 26. Taking a single rotating shaft 15 as an example, the transmission plate 16 connected thereto can be synchronously displaced by the lateral movement of the rotating shaft 15. During this displacement process, the push shaft 18 will slide along the groove wall of the displacement groove 32. By opening 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 be displaced in a direction away from the floating base 1, so that the distance between the spiral assembly 4 and the floating base 1 increases.

[0048] Considering that the lateral movement of seawater will also increase under windy weather conditions, when the flow of seawater is pushed from the spiral assembly 4 under large wave conditions, the seawater will encounter the floating base 1 and produce backflow, that is, at this time, a small amount of seawater backflow will occur between the floating base 1 and the spiral assembly 4. This phenomenon will become more obvious when other meteorological elements 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 rotation power generation of the spiral assembly 4 will not increase proportionally. Therefore, by controlling the spiral assembly 4 to stay 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 energy and wave energy cooperative combined power generation device is used, the floating base 1 floats on the sea surface through the cooperation of the anchor nail 31 and the anchor cable 30. 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 the waves come, the waves will drive the spiral component 4 to rotate. Through the rotation of the spiral component 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 do not only drive the spiral component 4 to rotate, but also have the characteristics of ups and downs, they will also drive the spiral component 4 to rise and fall vertically. In the process of ups and downs, 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 component 4 rises and falls vertically, the deflection rod 14 will be deflected, and the deflection transmission of the deflection rod 14 will cause the rotating shaft 15 to rotate. Thereby, the two transmission plates 16 are driven to deflect, and then the push shaft 18 is displaced in a circular arc trajectory with the rotating shaft 15 as the axis through the deflection of the two transmission plates 16. The circular 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, and then the piston plate 20 is vertically reciprocated in the piston cylinder 6. When the piston plate 20 moves vertically downward, the one-way pipe 21 is opened, and the external airflow is sucked into the piston cylinder 20 through the one-way pipe 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, 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. In this way, when the waves rise and fall, the airflow can be continuously discharged from the cooperative power generation plate 11, so that the auxiliary impeller 9 can rotate to generate electricity. This makes full use of the horizontal movement power generation and vertical fluctuation power generation of the sea surface waves, so that the natural utilization rate is stronger and the power generation effect is better;

[0050] In case of strong winds, since there are no shelters on the sea surface, the wind speed will increase significantly. In order to avoid excessive power variation of the generator 3, which will affect the long-term use safety of the power generation components, the change of the surrounding environment can be sensed by the sensing device at this time, and then the two waterproof cylinders 28 can be started. The adaptation plate 7 is driven by the two waterproof cylinders 28 to 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, and 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 shields the impeller 9, and then stop driving the two waterproof cylinders 28. In this way, when the wind speed is too high, the impeller 9 is shielded by the protective cylinder 10, so as to prevent 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 shields the impeller 9, 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 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] When the adaptation plate 7 moves vertically upward, 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] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
