Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and more particularly to a floating offshore wind power generation device. Background Art

[0002] Wind power generation is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some limitations on the use of onshore wind energy, such as large land area and noise pollution. Due to the abundant offshore wind energy resources and the feasibility of current technology, the ocean will become a rapidly developing wind power market. Offshore wind farms in Europe and the United States are on the eve of large-scale development. The sea area within a water depth of less than 50 meters along the eastern coast of my country is vast and very close to the power load center (economically developed coastal areas with power shortages). With the development and maturity of offshore wind farm technology, wind power will surely become an important source of energy for sustainable development in my country's eastern coastal areas.

[0003] Among them, the patent with announcement number CN216812025U discloses a floating offshore wind power generation equipment, including a floating platform and a power generation equipment body, the power generation equipment body is located above the floating platform, eight floating assemblies arranged in a ring shape are arranged outside the floating platform, and a mounting frame is arranged on the top of the floating platform; When the structure is in use, by setting a dual-axis servo motor, when the power generation equipment body is not in use, first start the first servo motor to drive the gear to rotate through the output shaft, so that the rack plate drives the sleeve to move downward, and then start the dual-axis servo motor to drive the threaded rod to rotate through the output shaft, so that the left and right threaded blocks drive the two protective frames to move relative to each other, thereby covering the power generation equipment body inside the protective frame, thereby effectively blocking the wind and sun at sea, greatly improving the service life of the equipment, but the power generation equipment body covered by the protective frame also affects the efficiency of wind power generation, and the device is also easily shaken by the waves, and cannot use the traction force generated by the waves to supply secondary energy, resulting in low power generation efficiency. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a floating offshore wind power generation device, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: A floating offshore wind power generation device comprises a support frame, on which a power generation assembly is arranged; The power generation assembly comprises a first generator arranged at one side of the bottom of the support frame, and a floating plate is arranged on the top of the first generator; A slide groove is provided on the upper surface of the floating plate, and a plurality of slide rails are slidably connected in the slide groove, and a plurality of the slide rails are movably connected with universal joints, and a vertical rod is fixedly provided on the top of the plurality of universal joints; A connecting frame is provided on the top of the floating plate, and a plurality of boosting cylinders are plugged into the connecting frame, and each of the boosting cylinders is located on the outside of the corresponding vertical rod. A rotating shaft is provided on the top of the boosting cylinder, and a plurality of first wind power generation blades are distributed on the outside of the rotating shaft. Pistons are installed on the tops of the plurality of vertical rods by bolts, and each of the pistons is slidably connected to the corresponding boosting cylinder.

[0006] It can be seen that in the above technical solution, when the floating plate and the extension cover are pushed by the waves, the supporting ball seat and the ball socket cavity will cause the floating plate to swing and tilt on the outside of the vertical axis. When the floating plate tilts, the slide groove and the slide rail rub against each other, so that the slide rail can drive the vertical rod, the universal joint and the piston to move back and forth in the booster cylinder through the traction force when the floating plate tilts. When the piston moves, it squeezes the airflow in the booster cylinder and allows the airflow to be transported to the air gathering cylinder through the duct. After the airflow in each booster cylinder is gathered in the air gathering cylinder, it will be ejected and contact the first wind turbine blade, and then the first wind turbine blade can be rotated again through the traction force transported by the high-pressure airflow, thereby improving the wind energy efficiency required by the first wind turbine blade, and then improving the power generation efficiency and effect; Optionally, in a possible embodiment, the top ends of the plurality of booster cylinders are all plugged with conduits for diversion, and the top ends of the conduits are all provided with a gas collecting cylinder, the gas collecting cylinder is located at the bottom of the rotating shaft, the rotating shaft is rotatably connected to the gas collecting cylinder, a second generator is provided at the top of the gas collecting cylinder, the rotating shaft extends into the second generator, a cross plate is provided at the top and bottom of the support frame, the first generator is fixedly provided at the bottom of the cross plate, a positioning column is fixedly provided at the bottom of the first generator, a second wind turbine blade is rotatably connected to the outer side of the positioning column, the second wind turbine blade is rotatably connected to the first generator, a plurality of pull ropes are distributed on the outer side of the positioning column, and the bottom end of each of the pull ropes is threadedly connected to a limited anchor, a ball socket cavity is opened through the middle part of the floating plate, a supporting ball seat is movably connected in the ball socket cavity, an extension cover is provided at the bottom of the floating plate, a vertical axis is fixedly provided on the supporting ball seat, the vertical axis extends to the connecting frame and is fixedly connected to the connecting frame, and the bottom of the vertical axis extends to the first generator; It can be seen that in the above technical solution, the device is positioned after installation through the limit anchor, the pull rope and the positioning column to prevent the device from being displaced due to the waves. At the same time, when the airflow on the sea surface contacts the second wind turbine blade and the first wind turbine blade, the first wind turbine blade drives the rotating shaft to rotate and the second wind turbine blade to generate wind power. By setting the extended cover, the contact area between the floating plate and the water surface is increased, and then the tension formed on the floating plate when the water waves are generated is increased, ensuring that the floating plate can be tilted significantly, increasing the pressure generated by the subsequent piston displacement squeezing the air, and making it easier for the first wind turbine blade to rotate and generate electricity.

[0007] Technical effects and advantages of the present invention: The present invention positions the device after installation through the limit anchor, the pull rope and the positioning column to prevent the device from being displaced due to the sea waves. At the same time, when the airflow on the sea surface contacts the second wind power generation blade and the first wind power generation blade, the first wind power generation blade drives the rotating shaft to rotate and the second wind power generation blade to generate wind power; When the floating plate is moved by the waves, the floating plate is swung and tilted outside the vertical axis through the support ball seat and the ball socket cavity. When the floating plate tilts, the slide groove and the slide rail rub against each other, and then the piston moves back and forth in the boosting cylinder. When the piston moves, the airflow in the boosting cylinder is squeezed and the airflow is transported to the air gathering cylinder through the conduit. After the airflow in each boosting cylinder is gathered in the air gathering cylinder, it is ejected and contacts the first wind power generation blade, and then the first wind power generation blade can be rotated again through the traction force transported by the high-pressure airflow, thereby improving the wind energy efficiency required by the first wind power generation blade, and then improving the power generation efficiency and effect. The present invention increases the contact area between the floating plate and the water surface by setting the extended cover, thereby increasing the tension formed on the floating plate when water waves are generated, ensuring that the floating plate can be tilted to a large extent, increasing the pressure generated by the subsequent piston displacement squeezing the air, and making it easier for the first wind power generation blade to rotate and generate electricity; To summarize, through the corresponding coordinated use of various structures, when the floating plate is tilted, the slide groove and the slide rail rub against each other, and then the piston moves back and forth in the boosting cylinder, so that the airflow can be transported to the air gathering cylinder through the duct, and the airflow in each boosting cylinder is gathered in the air gathering cylinder and then ejected to contact the first wind turbine blade, and then the first wind turbine blade can be rotated again by the traction force of the high-pressure airflow, thereby improving the wind energy efficiency required by the first wind turbine blade, and through the setting of the extended cover, the contact area between the floating plate and the water surface is increased, and then the tension formed on the floating plate when water waves are generated is increased, ensuring that the floating plate can be tilted significantly, and the pressure generated by the subsequent piston displacement squeezing the air is increased, which makes it easier for the first wind turbine blade to rotate and generate electricity, thereby ensuring the power generation efficiency.

DETAILED DESCRIPTION

[0017] 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.

[0018] As attached Figure 1-7The floating offshore wind power generation equipment shown in the figure has a power generation component arranged on the support frame 1. When the floating plate 4 is tilted, the slide groove 5 and the slide rail 6 rub against each other, thereby causing the piston 22 to move back and forth in the boosting cylinder 9, so that the airflow can be transported to the gas collecting cylinder 11 through the duct 10. The airflow in each boosting cylinder 9 is gathered in the gas collecting cylinder 11 and then ejected to contact the first wind power generation blade 13, thereby causing the first wind power generation blade 13 to rotate again through the traction force of the high-pressure airflow, thereby improving the wind energy efficiency required by the first wind power generation blade 13. The extension cover 21 is arranged to increase the contact area between the floating plate 4 and the water surface, thereby increasing the tension formed on the floating plate 4 when water waves are generated, thereby ensuring that the floating plate 4 can be tilted significantly, thereby increasing the pressure generated by the subsequent displacement of the piston 22 to squeeze the air, thereby making it easier for the first wind power generation blade 13 to rotate and generate electricity, thereby ensuring the power generation efficiency, and the specific structural arrangement of the component is as follows; The power generation assembly includes a first generator 3 arranged at one side of the bottom of the support frame 1, and a floating plate 4 is arranged on the top of the first generator 3; A slide groove 5 is provided on the upper surface of the floating plate 4, and a plurality of slide rails 6 are slidably connected in the slide groove 5. Universal joints 23 are movably connected to the plurality of slide rails 6, and vertical rods 7 are fixedly provided at the tops of the plurality of universal joints 23. A connecting frame 8 is provided on the top of the floating plate 4, and a plurality of boosting cylinders 9 are plugged into the connecting frame 8, and each boosting cylinder 9 is located on the outside of the corresponding vertical rod 7, and a rotating shaft 12 is provided on the top of the boosting cylinder 9, and a plurality of first wind turbine blades 13 are distributed on the outside of the rotating shaft 12. Pistons 22 are installed on the tops of the plurality of vertical rods 7 by bolts, and each piston 22 is slidably connected to the corresponding boosting cylinder 9.

[0019] The tops of the multiple booster cylinders 9 are all plugged with conduits 10 for diversion, and the tops of the conduits 10 are all provided with gas collecting cylinders 11, which are located at the bottom of the rotating shaft 12, and the rotating shaft 12 is rotatably connected to the gas collecting cylinder 11. A second generator 14 is provided on the top of the gas collecting cylinder 11, and the rotating shaft 12 extends into the second generator 14. The top and bottom of the support frame 1 are both provided with cross plates 2, and the first generator 3 is fixedly arranged at the bottom of the cross plate 2. A positioning column 15 is fixedly arranged at the bottom of the first generator 3, and the outer side of the positioning column 15 is rotatably connected to the second generator 14. The wind turbine blades 16 and the second wind turbine blades 16 are rotatably connected to the first generator 3. A plurality of pull ropes 17 are distributed on the outside of the positioning column 15, and the bottom end of each pull rope 17 is threadedly connected to the limit anchor 18. A ball socket cavity 19 is penetrated through the middle of the floating plate 4, and a supporting ball seat 20 is movably connected in the ball socket cavity 19. An extension cover 21 is provided at the bottom of the floating plate 4, and a vertical shaft 24 is fixedly provided on the supporting ball seat 20. The vertical shaft 24 extends to the connecting frame 8 and is fixedly connected to the connecting frame 8, and the bottom of the vertical shaft 24 extends to the first generator 3.

[0020] According to the above structure, when in use, the staff installs the device on the sea surface, and positions the device after installation through the limit anchor 18, the pull rope 17 and the positioning column 15 to prevent the device from being displaced due to the waves. At the same time, when the airflow on the sea surface contacts the second wind power generation blade 16 and the first wind power generation blade 13, the first wind power generation blade 13 drives the rotating shaft 12 to rotate and the second wind power generation blade 16 to generate wind power; When the device is installed, the floating plate 4 and the extension cover 21 are located on the sea surface. When the floating plate 4 and the extension cover 21 are moved by the waves, the supporting ball seat 20 and the ball socket cavity 19 will cause the floating plate 4 to swing and tilt on the outside of the vertical axis 24. When the floating plate 4 tilts, the slide groove 5 and the slide rail 6 rub against each other, so that the slide rail 6 can drive the vertical rod 7, the universal joint 23 and the piston 22 to move back and forth in the boosting cylinder 9 through the traction force when the floating plate 4 tilts. When the piston 22 moves, it squeezes the airflow in the boosting cylinder 9 and allows the airflow to be transported to the gas collecting cylinder 11 through the conduit 10. After the airflow in each boosting cylinder 9 is gathered in the gas collecting cylinder 11, it will be ejected and contact the first wind turbine blade 13, so that the first wind turbine blade 13 can be rotated again through the traction force of the high-pressure airflow, thereby improving the wind energy efficiency required by the first wind turbine blade 13, and then improving the power generation efficiency and effect. Furthermore, by setting the extended cover 21, the contact area between the floating plate 4 and the water surface is increased, thereby increasing the tension formed on the floating plate 4 when water waves are generated, ensuring that the floating plate 4 can be tilted significantly, increasing the pressure generated by the subsequent displacement of the piston 22 to squeeze the air, and making it easier for the first wind turbine blade 13 to rotate and generate electricity.

[0021] Different from the prior art, the present application discloses a floating offshore wind power generation equipment. When the floating plate 4 is tilted, the slide groove 5 and the slide rail 6 rub against each other, thereby causing the piston 22 to move back and forth in the boosting cylinder 9, so that the airflow can be transported to the gas collecting cylinder 11 through the duct 10. The airflow in each boosting cylinder 9 is gathered in the gas collecting cylinder 11 and then ejected to contact the first wind power generation blade 13, thereby causing the first wind power generation blade 13 to rotate again due to the traction force of the high-pressure airflow, thereby improving the wind energy efficiency required by the first wind power generation blade 13. By setting the extended cover 21, the contact area between the floating plate 4 and the water surface is increased, thereby increasing the tension formed on the floating plate 4 when water waves are generated, ensuring that the floating plate 4 can be tilted significantly, increasing the pressure generated by the subsequent displacement of the piston 22 to squeeze the air, making it easier for the first wind power generation blade 13 to rotate and generate electricity, thereby ensuring the power generation efficiency.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
