Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation, and in particular relates to a wind power generation device. Background Art

[0002] Offshore wind power generation is a renewable energy method that utilizes offshore wind energy resources to convert wind energy into electricity through wind turbines installed on or near the sea. Compared to onshore wind resources, offshore wind power is more abundant, wind speeds are more stable, and power generation efficiency is higher. It also avoids problems such as insufficient onshore wind reserves and environmental pollution.

[0003] Existing offshore wind power support technologies primarily fall into two categories: bottom-fixed support and suspended support. Suspended support includes buoy and semi-submerged support. The buoy support is primarily secured to the sea surface via several cables connected to seabed mooring anchors, with the wind turbine tower bolted to the buoy. However, due to the high winds and waves at sea, the buoy support is frequently impacted by waves, resulting in unstable wind turbine towers. Consequently, various improved support structures have emerged on the market. For example, Chinese Patent Publication No. CN214499320U discloses a high-wind-resistant offshore wind turbine. This structure, through the interaction of a floating plate, a wave-breaking ring, a speed reduction block, and a connecting block, addresses the vulnerability of offshore wind turbines to vibrations caused by waves and the effects of strong winds. Another example is Chinese Patent Publication No. CN113950444A, which discloses an offshore wind turbine buoy equipped with a ballast section and a pitch attenuation section to mitigate the effects of waves and improve stability. For example, the Chinese patent publication number CN214499321U discloses an offshore wind power generation equipment with a stable base. The equipment can reinforce the tower by providing a reinforcement plate, a load-reducing groove and a secondary reinforcement ring to prevent it from being damaged in strong winds, thereby improving the stability of the tower.

[0004] The above-mentioned patents either increase the strength of the buoy support components or add buffer structures to reduce the impact of waves to improve the wind resistance and stability of offshore wind power generation equipment. However, there are few structures or equipment that dynamically respond to and control the rise and fall of the buoy support according to the size of strong winds and waves. As a result, the prevention of offshore wind power generation equipment against strong winds and waves is one-sided, making it difficult to fully ensure the safety of offshore power generation equipment in strong wind environments at sea.

[0005] Therefore, in order to solve the above technical problems, it is necessary to provide a wind power generation equipment.

[0006] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0007] The object of the present invention is to provide a wind power generation device that can solve the safety problem of offshore power generation equipment in a strong wind environment at sea.

[0008] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0009] A wind power generation device, comprising: a wind power generation main body, a buoy support mechanism, a snorkeling control mechanism and a force-dissipating wave-proof mechanism;

[0010] The buoy support mechanism is connected to the wind power generation body, and the buoy support mechanism includes a floating body, a mounting plate is fixedly connected to the floating body, the wind power generation body is mounted on the mounting plate, and a plurality of anchor cables are connected to the floating body;

[0011] The snorkeling control mechanism is installed in the buoy, and is used to control the buoy support mechanism to dive quickly in strong wind weather;

[0012] The force-reducing and wave-proofing mechanism is rotatably connected to the outer side of the mounting plate. The force-reducing and wave-proofing mechanism is used to reduce the impact of waves. At the same time, when the buoy support mechanism dives, the force-reducing and wave-proofing mechanism is triggered by the snorkeling control mechanism and is used to further increase the stability of the wind power generation body.

[0013] In one or more embodiments of the present invention, the floating body is shaped like a tumbler, so that the center of gravity of the buoy support mechanism is close to the bottom. When the buoy support mechanism is impacted by waves or the wind turbine body is subjected to strong winds, gravity will generate a torque that resets the buoy support mechanism, thereby maintaining the stability of the wind turbine body.

[0014] The top wall of the mounting plate is connected to a wave-proof protective member, which wraps one end of the wind power generation body. The wave-proof protective member is used to protect the connection between the wind power generation body and the mounting plate to avoid being impacted by waves.

[0015] In one or more embodiments of the present invention, a liquid storage chamber is provided within the buoy, and the liquid storage chamber is used to accommodate the annular tube and seawater. When seawater enters the liquid storage chamber, the buoy support mechanism can dive, so that the buoy support mechanism is not affected by the impact of sea waves. At the same time, when the buoy support mechanism dives, it can drive the wind turbine body downward, thereby reducing the contact area between the wind turbine body and strong winds, and improving the stability of the wind turbine body in strong winds.

[0016] The snorkeling control mechanism includes an annular tube, which is arranged on the bottom wall of the liquid storage chamber. A plurality of first water spray heads are obliquely installed on the annular tube and evenly distributed around the circumference. The annular tube is connected to a liquid inlet pipe, one end of which passes through the float. A first control valve is installed on the liquid inlet pipe. When the first control valve is opened, seawater enters the annular tube through the liquid inlet pipe and is then discharged to the liquid storage chamber through a plurality of first water spray heads, thereby increasing the seawater capacity in the liquid storage chamber so that the buoy support mechanism can dive.

[0017] In one or more embodiments of the present invention, a plurality of guide rods are connected between the upper and lower walls of the liquid storage chamber, and the guide rods are used to stabilize the compression plate to prevent the compression plate from deflecting when sliding in the liquid storage chamber;

[0018] A compression plate is slidably connected between the guide rods, and a sealing gasket is provided between the compression plate and the side wall of the liquid storage chamber. When seawater enters the liquid storage chamber, the compression plate can move upward in the liquid storage chamber under the action of seawater, and the upward-moving compression plate can compress the gas in the upper part of the liquid storage chamber.

[0019] In one or more embodiments of the present invention, an impeller is rotatably connected to the float, and the plurality of first water spray heads correspond to the impeller. When seawater is discharged through the first water spray heads, the seawater impacts the impeller due to the inclined arrangement of the first water spray heads, causing the impeller to rotate within the float.

[0020] The impeller is connected to a rotating shaft, and one end of the rotating shaft away from the impeller is connected to a pair of winding rollers. A winding cavity matching the winding rollers is provided in the float. When the impeller rotates, the impeller drives the rotating shaft and the winding rollers to rotate.

[0021] In one or more embodiments of the present invention, a pull rope is wound around the winding roller, and a pair of guide wheels are installed in the float. One end of the pull rope is passed around the guide wheel and connected to the compression plate. When the winding roller rotates, the winding roller can wrap around the pull rope and, under the action of the guide wheel, can further pull the compression plate upward in the liquid storage chamber so as to better compress the gas on the upper side of the liquid storage chamber.

[0022] In one or more embodiments of the present invention, an air collection cavity is provided in the mounting plate, a second connecting tube is connected between the air collection cavity and the liquid storage cavity, a temporary storage cavity is provided on the outer wall of the mounting plate, a plurality of first connecting tubes are connected between the air collection cavity and the temporary storage cavity, and the compressed gas in the liquid storage cavity enters the air collection cavity through the second connecting tube, and then enters the temporary storage cavity through the plurality of first connecting tubes.

[0023] In one or more embodiments of the present invention, the force-reducing and wave-proofing mechanism includes an inner ring, which is rotatably connected to the outer wall of the mounting plate, so that the force-reducing and wave-proofing mechanism can rotate around the outer wall of the mounting plate to reduce the impact of waves on the force-reducing and wave-proofing mechanism, thereby greatly reducing the intensity of the wave impact.

[0024] The inner ring covers the temporary storage cavity, and a sealing bearing is connected between the inner ring and the mounting plate to prevent the compressed gas in the temporary storage cavity from leaking through the gap between the inner ring and the mounting plate;

[0025] An outer ring is provided outside the inner ring, and a plurality of connecting pipes are connected between the inner ring and the outer ring.

[0026] In one or more embodiments of the present invention, the outer ring and the connecting tubes are both hollow tubes. As the gas in the temporary storage chamber gradually increases, the gas in the temporary storage chamber enters the outer ring through the inner ring and the connecting tubes.

[0027] The outer ring sidewall is provided with a plurality of air holes, and the outer side of the air holes is covered with an air bag. The gas in the outer ring enters the air bag through the air holes, causing the air bag to expand. The expanded air bag can increase the buoyancy of the entire force-relieving and wave-proofing mechanism, ensuring the stability of the buoy support mechanism when diving. At the same time, the expanded force-relieving and wave-proofing mechanism can also reduce the impact of waves on the wind turbine main body.

[0028] The airbag and the connecting pipe are spaced apart from each other, and the outer side of the connecting pipe is wrapped with a rubber ring, which is also used to increase the buoyancy of the entire force-relieving and wave-proofing mechanism.

[0029] In one or more embodiments of the present invention, a liquid pump is installed in the float, the liquid pumping end of the liquid pump is connected to the annular tube, the liquid outlet end of the liquid pump is connected to a drainage ring pipe, the drainage ring pipe is arranged outside the float, and a plurality of second water spray heads evenly distributed around the circumference are connected to the drainage ring pipe, the second water spray heads are vertically downward, and when the float support mechanism needs to rise, the liquid pump is operated, and the liquid pump extracts seawater in the liquid storage chamber through the extraction end, the annular tube and the first water spray head, and the seawater is discharged through the drainage ring pipe and the second water spray head. When the seawater is discharged through the second water spray head, a reaction force is generated to accelerate the floating speed of the float support mechanism.

[0030] Compared with the existing technology, the wind power generation equipment of the present invention can dynamically respond to and control the rise and fall of the buoy support of the offshore power generation equipment according to the strong wind and wave conditions at sea, so as to greatly reduce the impact of strong wind and waves on the buoy support, thereby improving the stability and safety of the use of offshore power generation equipment.

DETAILED DESCRIPTION

[0051] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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 making creative efforts should fall within the scope of protection of the present invention.

[0052] like Figures 1 to 17 As shown, a wind power generation device in one embodiment of the present invention includes a wind power generation body 1, a buoy support mechanism 2, a buoyancy control mechanism 3, a force-dissipating and wave-proofing mechanism 4, a liquid pump 5 and blades 6.

[0053] Preferably, a wind speed sensor is installed on the side wall of the wind power generation body 1, which is used to dynamically respond to and control the rise and fall of the buoy support mechanism 2 according to the wind force level measured by the wind speed sensor, so as to reduce the impact of strong winds and waves on the wind power generation body 1 and ensure the safety of the wind power generation body 1.

[0054] like Figures 1 to 17 As shown, the buoy support mechanism 2 is connected to the wind power generation body 1. The buoy support mechanism 2 is used to install the wind power generation body 1 so that the wind power generation body 1 can generate electricity at sea.

[0055] The buoy support mechanism 2 includes a float 201, which is in the shape of a tumbler. Figure 2 The state shown can make the overall center of gravity of the buoy support mechanism 2 close to the bottom. When the buoy support mechanism 2 is impacted by waves or the wind power generation body 1 is affected by strong winds, gravity will generate a torque to reset the buoy support mechanism 2, thereby keeping the wind power generation body 1 stable.

[0056] In addition, a mounting plate 202 is fixedly connected to the floating body 201 , and the wind power generation body 1 is mounted on the mounting plate 202 by bolts.

[0057] Specifically, the top wall of the mounting plate 202 is connected to a wave-proof protective member 203, which wraps one end of the wind turbine body 1. The wave-proof protective member 203 is used to protect the connection between the wind turbine body 1 and the mounting plate 202 to avoid being impacted by waves.

[0058] In addition, a number of anchor cables 204 are connected to the floating body 201 , and the position of the buoy support mechanism 2 can be fixed by using the anchor cables 204 to ensure the stability and safety of the wind power generation body 1 .

[0059] like Figures 2 to 8 As shown, the mounting plate 202 is provided with an air collecting chamber 2021, a second connecting pipe 206 connecting the air collecting chamber 2021 and the liquid storage chamber 205. A temporary storage chamber 2022 is provided on the outer wall of the mounting plate 202, and a plurality of first connecting pipes 2023 are connected between the air collecting chamber 2021 and the temporary storage chamber 2022. The compressed gas in the liquid storage chamber 205 enters the air collecting chamber 2021 through the second connecting pipe 206, and then enters the temporary storage chamber 2022 through the plurality of first connecting pipes 2023.

[0060] like Figures 1 to 8As shown, a liquid storage chamber 205 is provided in the float 201, and the liquid storage chamber 205 is used to accommodate the annular tube 301 and seawater. When seawater enters the liquid storage chamber 205, the buoy support mechanism 2 can dive, so that the buoy support mechanism 2 will not be affected by the impact of sea waves. At the same time, when the buoy support mechanism 2 dives, it can drive the wind power generation body 1 to move downward, so as to reduce the contact area between the wind power generation body 1 and strong wind, improve the stability of the wind power generation body 1 in strong wind weather, and ensure the safe use of the wind power generation body 1.

[0061] like Figures 1 to 17 As shown, the snorkeling control mechanism 3 is installed in the floating body 201. In strong wind weather, the snorkeling control mechanism 3 is used to control the buoy support mechanism 2 to dive quickly to avoid the buoy support mechanism 2 being affected by the impact of waves, avoid the wind power generation body 1 being affected by strong winds, and improve the stability and safety of the wind power generation body 1.

[0062] The snorkeling control mechanism 3 includes an annular tube 301, which is mounted on the bottom wall of the liquid storage chamber 205. Multiple first water spray heads 302 are evenly distributed around the circumference of the annular tube 301 and are tilted. A liquid inlet pipe is connected to the annular tube 301, one end of which passes through the float 201. A first control valve is mounted on the liquid inlet pipe. When the first control valve is opened, seawater enters the annular tube 301 through the liquid inlet pipe and is then discharged into the liquid storage chamber 205 through the multiple first water spray heads 302. This increases the seawater volume within the liquid storage chamber 205, allowing the buoy support mechanism 2 to submerge.

[0063] In addition, a plurality of guide rods 303 are connected between the upper and lower walls of the liquid storage chamber 205 . The guide rods 303 are used to guide the sliding of the compression plate 304 to prevent the compression plate 304 from deflecting when sliding in the liquid storage chamber 205 .

[0064] Preferably, a limiting column is provided on the side wall of the guide rod 303 to prevent the compression plate 304 from colliding with the impeller 305 .

[0065] Specifically, compression plates 304 are slidably connected between the guide rods 303. These plates are used to block seawater, preventing it from entering the outer ring 402, and also to compress the air within the liquid storage chamber 205. Sealing gaskets 3041 are provided between the compression plates 304 and the sidewalls of the liquid storage chamber 205. When seawater enters the liquid storage chamber 205, the compression plates 304 are forced upward within the chamber 205 by the seawater. Simultaneously, because the sealing gaskets 3041 are provided between the compression plates 304 and the inner wall of the chamber 205, the upward movement of the compression plates 304 compresses the air above the chamber 205.

[0066] Furthermore, an impeller 305 is rotatably connected to the floating body 201, and each of the plurality of first water spray heads 302 corresponds to the impeller 305. When seawater is discharged through the first water spray heads 302, due to the inclined arrangement of the first water spray heads 302, the seawater forms a spiral flow within the liquid storage chamber 205. The spiral flow impacts the impeller 305, causing the impeller 305 to rotate within the floating body 201.

[0067] like Figures 1 to 17 As shown, the impeller 305 is connected to a rotating shaft 306. The end of the rotating shaft 306 away from the impeller 305 is connected to a pair of winding rollers 307. The floating body 201 is provided with a winding chamber that matches the winding rollers 307. When the impeller 305 rotates, the impeller 305 drives the rotating shaft 306 and the winding rollers 307 to rotate.

[0068] A pull rope 308 is wound around the winding roller 307. A pair of guide wheels 309 are installed in the float 201. One end of the pull rope 308 passes through the guide wheels 309 and is connected to the compression plate 304. When the winding roller 307 rotates, the winding roller 307 can wrap around the pull rope 308. Under the action of the guide wheels 309, the compression plate 304 can be further pulled upward within the liquid storage chamber 205 to further compress the gas on the upper side of the liquid storage chamber 205.

[0069] In addition, the other end of the impeller 305 is connected to a polygonal connecting post 310 . When the impeller 305 rotates, the impeller 305 can also drive the polygonal connecting post 310 to rotate.

[0070] like Figures 1 to 17 As shown, the force-reducing and wave-proofing mechanism 4 is rotatably connected to the outside of the mounting plate 202. The force-reducing and wave-proofing mechanism 4 is used to reduce the impact of waves on the wind power generation body 1. At the same time, when the buoy support mechanism 2 dives, the force-reducing and wave-proofing mechanism 4 is triggered by the buoyancy control mechanism 3 and is used to further increase the stability of the wind power generation body 1 when diving.

[0071] The force-relieving and wave-proofing mechanism 4 includes an inner ring 401, which is rotatably connected to the outer wall of the mounting plate 202. If waves strike the outer ring 402, the inner ring 401 and the mounting plate 202 are rotatable, thereby relieving the wave impact on the outer ring 402 and significantly reducing the intensity of the wave impact.

[0072] In addition, the inner ring 401 covers the temporary storage cavity 2022, and a sealed bearing is connected between the inner ring 401 and the mounting plate 202 to prevent the compressed gas in the temporary storage cavity 2022 from leaking through the gap between the inner ring 401 and the mounting plate 202, so that the airbag 404 can expand.

[0073] Specifically, an outer ring 402 is disposed outside the inner ring 401, and a plurality of connecting tubes 403 are connected between the inner ring 401 and the outer ring 402. Gas in the temporary storage chamber 2022 enters the outer ring 402 through the connecting tubes 403, and then enters the airbag 404 through the air holes 4021, causing the airbag 404 to expand. The expanded airbag 404 can increase the stability of the buoy support mechanism 2 during diving.

[0074] In addition, the outer ring 402 and the connecting tubes 403 are both hollow tubes. As the gas in the temporary storage chamber 2022 gradually increases, the gas in the temporary storage chamber 2022 enters the outer ring 402 through the inner ring 401 and the connecting tubes 403 .

[0075] Preferably, the connecting tube 403 is an elastic, retractable hose. When the buoy support mechanism 2 is raised, the retractability of the connecting tube 403 allows the outer ring 402 to float on the sea surface, forming a wave-breaking ring outside the buoy support mechanism 2 and providing a wave-proof effect. When the buoy support mechanism 2 is submerged, the outer ring 402 floats on the sea surface under the action of the inflatable airbag 404, and the outer ring 402 also serves as a wave-proof function, protecting the wind turbine body 1 from the impact of waves.

[0076] like Figures 9 to 11 As shown, the sidewall of the outer ring 402 is provided with a plurality of air holes 4021, and the outer side of the air holes 4021 is covered with an air bag 404. The gas in the outer ring 402 enters the air bag 404 through the air holes 4021, causing the air bag 404 to expand. The expanded air bag 404 can increase the buoyancy of the entire drag and wave protection mechanism 4, ensuring that the drag and wave protection mechanism 4 can float on the sea surface when the buoy support mechanism 2 dives, thereby utilizing the outer ring 402 to enhance the wave protection effect, and also improve the stability of the buoy support mechanism 2 when diving.

[0077] Preferably, the air bag 404 and the connecting tube 403 are spaced apart from each other, such as Figure 9 As shown, the outer side of the connecting pipe 403 is wrapped with a rubber ring 405, which is also used to increase the buoyancy of the entire drag and wave protection mechanism 4, so that when the buoy support mechanism 2 dives, the drag and wave protection mechanism 4 can float on the sea surface.

[0078] Among them, a plurality of wave-breaking columns 406 are slidably connected to the outer ring 402, and one end of the wave-breaking column 406 located inside the outer ring 402 is connected to the connecting seat 407. When gas enters the outer ring 402, the gas will also exert a force on the connecting seat 407. Under the force of the gas, the connecting seat 407 drives the wave-breaking column 406 to move, so that the wave-breaking column 406 protrudes from the outer ring 402, that is, Figure 9 In the state shown, the connection seat 407 can be used to split the waves, thereby further reducing the impact of the waves on the wind power generation body 1.

[0079] In addition, a sealing ring is provided at the joint between the wave-splitting column 406 and the outer ring 402 to prevent the gas in the outer ring 402 from leaking through the joint between the outer ring 402 and the wave-splitting column 406, so as to ensure that the airbag 404 can be expanded.

[0080] like Figures 1 to 17 As shown, a liquid pump 5 is installed in the float 201. The liquid pumping end of the liquid pump 5 is connected to the annular pipe 301. The liquid outlet end of the liquid pump 5 is connected to the drainage ring pipe 501. The drainage ring pipe 501 is arranged outside the float 201. The drainage ring pipe 501 is connected to a plurality of second water spray heads 502 evenly distributed around the circumference. The second water spray heads 502 are vertically downward. When the buoy support mechanism 2 needs to rise from a submerged state, the liquid pump 5 is operated. The liquid pump 5 extracts seawater from the liquid storage chamber 205 through the extraction end, the annular pipe 301 and the first water spray head 302. The seawater is discharged through the drainage ring pipe 501 and the second water spray head 502. When the second water spray head 502 discharges the seawater, a reaction force is generated, which can reversely push the buoy support mechanism 2 to rise, thereby accelerating the buoy support mechanism 2 to float up.

[0081] At the same time, when the liquid pump 5 extracts seawater from the liquid storage chamber 205, under the action of multiple first water spray heads 302, a rotating water flow can also be formed in the liquid storage chamber 205. The rotating water flow will drive the impeller 305 to rotate in the opposite direction, and then drive the winding roller 307 to rotate in the opposite direction. The reverse rotating winding roller 307 will release the pull rope 308, and the compression plate 304 will move downward in the liquid storage chamber 205 under the action of gravity and the reaction force of the gas of the expansion airbag 404, so as to perform the diving operation again later.

[0082] Preferably, a second control valve is installed at the pumping end of the liquid pump 5 to prevent seawater in the liquid storage chamber 205 from flowing back through the liquid pump 5 when the buoy support mechanism 2 dives.

[0083] like Figures 1 to 17 As shown, paddles 6 are rotatably connected to the float 201, and are used to further increase the diving or surfacing speed of the buoy support mechanism 2. A plurality of second water spray heads 502 are each associated with the paddles 6. The seawater discharged from the second water spray heads 502 also impacts the paddles 6, causing the paddles 6 to rotate faster, thereby increasing their surfacing speed.

[0084] One end of the blade 6 located within the buoy 201 is connected to a connecting sleeve 601, and a polygonal connecting column 310 is disposed within the connecting sleeve 601. The sidewall of the connecting sleeve 601 is provided with at least one telescopic member 602, which corresponds to the polygonal connecting column 310. When the telescopic member 602 is extended, the polygonal connecting column 310 and the connecting sleeve 601 can be linked. That is, when the impeller 305 rotates, the impeller 305 also drives the blade 6 to rotate, thereby accelerating the speed at which the buoy support mechanism 2 dives or rises. Especially in strong winds and large waves, accelerating the dive can shorten the time that the wind turbine body 1 is affected, thereby ensuring the safety and stability of the wind turbine body 1.

[0085] Preferably, an anchor cable tensioning mechanism can also be installed in the float 201. When the buoy support mechanism 2 dives, the anchor cable 204 can be tightened by using the anchor cable tensioning mechanism, which can not only ensure the stability of the buoy support mechanism 2 when diving, but also cooperate with the seawater in the liquid storage chamber 205 and the action of the blades 6 to increase the diving speed of the buoy support mechanism 2, thereby shortening the impact of strong winds and waves on the wind power generation body 1.

[0086] Specifically, the anchor cable tensioning mechanism includes an electric motor, the output end of which is connected to a winding disk, around which the anchor cable 204 is wound. When the motor is running, it drives the winding disk to rotate, which then winds around the anchor cable 204, thereby tightening the anchor cable 204. The electric motor is a servo motor with a self-locking mechanism to prevent the winding disk from rotating.

[0087] In practice, a wind speed sensor on the side wall of the wind turbine 1 is used to measure the wind speed on the sea surface. If the wind speed is low, the buoy support mechanism 2 does not need to be submerged. If the wind speed is high, the sea surface is often accompanied by large waves. Therefore, it is necessary to quickly and dynamically respond to control the buoy support mechanism 2 to submerge below the sea surface level, thereby reducing the impact of waves on the buoy support mechanism 2 and reducing the contact area of ​​the wind turbine 1 with strong winds, thereby ensuring the stability and safety of the wind turbine 1.

[0088] When controlling the buoy support mechanism 2 to dive, the first control valve on the liquid inlet pipe is opened. Since the pressure outside the float 201 is greater than the pressure inside the liquid storage chamber 205, the seawater outside the float 201 will quickly enter the annular tube 301 through the liquid inlet pipe, and then be discharged to the liquid storage chamber 205 through several first water spray heads 302, which is used to increase the seawater capacity in the liquid storage chamber 205 and increase the overall mass of the buoy support mechanism 2, so that the buoy support mechanism 2 can dive.

[0089] When seawater is discharged into the liquid storage chamber 205 through the first water spray head 302, the inclined arrangement of the first water spray head 302 creates a strong spiral flow within the liquid storage chamber 205. This spiral flow impacts the impeller 305, causing it to rotate within the floating body 201. The impeller 305 drives the rotating shaft 306 and the winding roller 307 to rotate. The rotating winding roller 307 winds around the pull rope 308, which, under the action of the guide wheel 309, pulls the compression plate 304 upward within the liquid storage chamber 205, thereby compressing the gas above the compression plate 304.

[0090] The compressed gas within the liquid storage chamber 205 flows through the second connecting tube 206 into the gas collection chamber 2021, and then through the plurality of first connecting tubes 2023 into the temporary storage chamber 2022. Because the inner ring 401 is pivotally connected to the sidewall of the mounting plate 202, the gas within the temporary storage chamber 2022 flows through the connecting tube 403 into the outer ring 402, and then through the air hole 4021 into the airbag 404, causing it to expand. The expanded airbag 404 increases the buoyancy of the drag and wave protection mechanism 4, allowing it to float on the sea surface when the buoy support mechanism 2 submerges.

[0091] In addition, when seawater enters the liquid storage chamber 205, the telescopic part 602 is controlled to extend, so that the polygonal connecting column 310 and the connecting sleeve 601 can be linked, that is, when the impeller 305 rotates, the impeller 305 can also drive the blades 6 to rotate. The rotating blades 6 can accelerate the diving speed of the buoy support mechanism 2, thereby shortening the time that the wind power generation body 1 is affected by the waves, and improving the safety and stability of the wind power generation body 1.

[0092] When the liquid storage chamber 205 is filled with seawater, the buoy support mechanism 2 can be completely submerged below the sea level, preventing the impact of waves on the buoy support mechanism 2 and improving the stability of the buoy support mechanism 2. At the same time, because the connecting tube 403 is made of a retractable material and the airbag 404 is filled with gas, the force-relieving wave-breaking mechanism 4 can float on the sea surface, forming a wave-breaking circle outside the wind turbine body 1, preventing direct impact of waves on the wind turbine body 1.

[0093] When the buoy support mechanism 2 needs to ascend from a submerged state, the liquid extraction pump 5 is operated. The liquid extraction pump 5 extracts seawater from the liquid storage chamber 205 through the extraction end, the annular pipe 301, and the first water spray head 302. The seawater is then discharged through the drainage annular pipe 501 and the second water spray head 502, thereby reducing the overall mass of the buoy support mechanism 2 and allowing the buoy support mechanism 2 to ascend. When the second water spray head 502 discharges the seawater, a reaction force is generated, which in turn pushes the buoy support mechanism 2 upward, thereby accelerating the buoy support mechanism 2's surfacing speed.

[0094] At the same time, as the liquid pump 5 extracts seawater from the liquid storage chamber 205, the multiple first water spray heads 302 also create a rotating water flow within the liquid storage chamber 205. This rotating water flow drives the impeller 305 to rotate in the opposite direction, which in turn drives the winding roller 307 to rotate in the opposite direction. The reverse rotation of the winding roller 307 releases the pull rope 308, and the compression plate 304 moves downward within the liquid storage chamber 205 under the action of gravity and the reaction force of the gas from the inflatable airbag 404, allowing for subsequent diving operations.

[0095] The counter-rotating impeller 305 can also drive the blades 6 to rotate in the opposite direction. At this time, the counter-rotating blades 6 can generate buoyancy to further accelerate the floating speed of the buoy support mechanism 2 and ensure that the wind power generation body 1 can be used normally.
