Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a wind power generation floating platform with a position adjustment function and a use method thereof. Background Art

[0002] Wind power generation is an important area of ​​renewable energy development, with advantages such as mitigating climate change, improving energy security, and promoting low-carbon economic growth. Due to the abundant offshore wind energy resources and the feasibility of current technology, the ocean will become a rapidly developing wind power market.

[0003] For example, Chinese utility model patent CN209100196U discloses a floating offshore wind power generation device, including a buoyancy device, which is a cavity structure, a water inlet is provided at the bottom of the buoyancy device, a wind turbine tower is installed at the top of the buoyancy device, and the buoyancy device is connected to the inflation device through a ventilation pipe. When it is necessary to lower the height of the offshore wind turbine unit, the buoyancy device is connected to the outside world through the ventilation pipe. At this time, due to the reduction of buoyancy, the entire wind turbine unit will be lowered to the seabed; when it is necessary to increase the height of the offshore wind turbine unit, the inflation device is used to inflate the cavity of the buoyancy device through the ventilation pipe. At this time, due to the increase of buoyancy, the entire wind turbine unit will be raised.

[0004] However, when the spherical buoyancy tank is affected by sea waves, the liquid inside will produce a wave effect, which increases the impact force of the liquid on the spherical buoyancy tank, causing the position of the spherical buoyancy tank to be unstable, thereby increasing the instability of the wind turbine main engine above; moreover, during the lowering process of the wind turbine unit, the traction device will become loose, causing the lateral position of the spherical buoyancy tank, wind turbine main engine, etc. to be unstable. If a large lateral offset occurs, there will be a certain safety risk.

[0022] Furthermore, the bottom of the second pipeline is located at the lower end of the buoy.

[0023] A method for using the wind power generation floating platform with position adjustment function comprises the following steps:

[0024] 1. When the water level of the floating wind power generation platform needs to be lowered, the water pump is started to suck seawater from the first pipe and then injected into the buoy through the second pipe;

[0025] At the same time, the first linear drive assembly extends and drives the first connecting block to rotate clockwise, and the first connecting block drives the fourth support frame close to the first linear drive assembly to rotate along the third support frame close to the first linear drive assembly in a direction away from the brake pad. At the same time, the first connecting block pushes the fourth support frame away from the first linear drive assembly through the connecting rod to rotate along the third support frame away from the first linear drive assembly in a direction away from the brake pad. The two fourth support frames respectively drive the arc clamping plates to move outward, so that the fourth support frame drives the arc clamping plates to separate from the brake pads fixed on the horizontal axis; then the first motor is started to drive the horizontal axis to rotate clockwise, and then the rotating winding ring and the rotating ring are driven to rotate clockwise, and the rotating winding ring is used to retract the second steel rope. When the first wedge block is in a state of contraction, the second linear drive assembly is in a state of contraction, the transverse connecting plate is not in contact with the fixed side plate, and the fixed side plate moves upward under the elastic restoring force of the second spring, driving the second trapezoidal block to move upward and be stuck between the adjacent first wedge blocks; the rotating ring rotates to drive the first wedge block to rotate clockwise, and the inclined surface of the first wedge block contacts the upper end inclined surface of the second trapezoidal block, pushing the second trapezoidal block to move downward along the first side supporting plate; during the winding process, because the plane of the first wedge block contacts the upper end plane of the second trapezoidal block when the first wedge block rotates counterclockwise, it is blocked by the second trapezoidal block, so the first wedge block cannot rotate counterclockwise, and thus the rotating ring, the transverse axis, and the rotating winding ring cannot rotate counterclockwise;

[0026] 2. When the water level of the floating wind power generation platform needs to be raised, the second linear drive assembly is first started to extend and drive the horizontal connecting plate to move downward to contact the fixed side plate and push the fixed side plate to move downward, and the fixed side plate drives the second trapezoidal block to move downward and separate from the first wedge-shaped block;

[0027] Then, the water pump is started to suck seawater from the second pipe and then discharged through the first pipe, so that the seawater in the buoy is reduced. Due to the increase in buoyancy, the floating platform for wind power generation gradually rises; at the same time, the first motor is started to drive the horizontal axis to rotate counterclockwise, and then drive the rotating winding ring to rotate counterclockwise to release the line; when releasing the line, the elastic restoring force of the third spring drives the slide plate to move upward, and the slide plate drives the second support wheel to move upward and press on the second steel rope, thereby tensioning the second steel rope;

[0028] At the same time, since the second steel rope is in contact with the second supporting wheel and the third spring is always in a stretched state, the third spring has a force to push the slide plate upward. When the buoy shakes, the second steel rope becomes loose, and the elastic restoring force of the third spring drives the slide plate upward. The slide plate drives the second supporting wheel to move upward and presses on the second steel rope, which helps the second steel rope to tend to a straightened state. The force exerted by the second supporting wheel on the second steel rope is conducive to realizing the buoy being reset to a vertical state.

[0029] 3. The first linear drive component is contracted to drive the first connecting block to rotate counterclockwise, and the first connecting block drives the fourth support frame close to the first linear drive component to rotate along the third support frame close to the first linear drive component toward the brake pad. At the same time, the first connecting block pushes the fourth support frame away from the first linear drive component to rotate along the third support frame away from the first linear drive component toward the brake pad through the connecting rod, and the two fourth support frames respectively drive the arc clamping plates to move inward, so that the fourth support frames drive the arc clamping plates to contact the brake pads fixed on the horizontal axis, and the two arc clamping plates brake the horizontal axis to achieve braking of the first motor;

[0030] 4. Regularly start the winder to drive the first steel rope to pay out or wind up. The first steel rope drives the counterweight sliding plate to move up and down. When the counterweight sliding plate moves, the marine life on the outer wall of the second steel rope is scraped off.

[0031] The present invention has the following beneficial effects: when the present invention is subjected to sea waves, the anti-disturbance annular plate can reduce the impact force of the seawater inside the buoy on the buoy, which is beneficial to improving the stability of the buoy, thereby ensuring that the wind turbine host above is more stable;

[0032] When the water level of the floating wind power generation platform needs to be lowered due to strong offshore waves, the present invention starts the water pump to suck seawater from the first pipe and then injects it into the lower part of the buoy through the second pipe, thereby reducing the impact force of water on the buoy when it enters; at the same time, it cooperates with multiple groups of anti-disturbance annular plates to ensure the stability of the overall movement of the floating wind power generation platform; at the same time, the winding ring is rotated to wind up the second steel rope, at which time the second linear drive assembly is in a retracted state, the transverse connecting plate is not in contact with the fixed side plate, and the fixed side plate moves upward under the elastic restoring force of the second spring, driving the second trapezoidal block to move upward and be stuck between the adjacent first wedge-shaped blocks; the rotating ring rotates clockwise, driving the second linear drive assembly to move upward and be stuck between the adjacent first wedge-shaped blocks. When a wedge block rotates, the inclined surface of the first wedge block contacts the upper inclined surface of the second trapezoidal block, pushing the second trapezoidal block to move downward along the first side support plate, and the rotating ring can rotate smoothly; during the winding process, since the plane of the first wedge block contacts the upper plane of the second trapezoidal block when the first wedge block rotates counterclockwise, it is blocked by the second trapezoidal block, and therefore the first wedge block cannot rotate counterclockwise, thereby making it impossible for the rotating ring, the horizontal axis, and the rotating winding ring to rotate counterclockwise, thereby ensuring stability during the winding process; the present invention can always keep the lateral position of the float, the mounting cylinder, the fan cylinder, etc. relatively stable, thereby reducing the safety risks caused by lateral deviation.

[0033] When the offshore environment returns to normal and the water level of the wind power generation floating platform needs to be raised, the present invention starts the water pump to suck seawater from the second pipe and then discharges it through the first pipe, so that the seawater in the buoy is reduced. Due to the increased buoyancy, the wind power generation floating platform gradually rises; at the same time, the second linear drive component is started to extend and drive the transverse connecting plate to move downward to contact the fixed side plate and push the fixed side plate to move downward, the fixed side plate drives the second trapezoidal block to move downward and separate from the first wedge block, and the first motor is started to rotate the rotating winding ring to release the line; when defending the line, the elastic restoring force of the third spring drives the slide plate to move upward, and the slide plate drives the second supporting wheel to move upward and press on the second steel rope, thereby realizing the tensioning effect of the second steel rope, ensuring the stable line release effect, avoiding the second steel rope from becoming loose due to excessive line release, resulting in inconsistent release lengths of the second steel ropes at multiple positions, causing the buoy to tilt, which is beneficial to improving the stability of line release.

[0034] The present invention can periodically start the winder to drive the first steel rope to pay out or wind up, and the first steel rope drives the counterweight sliding plate to move up and down. When the counterweight sliding plate moves, the marine organisms on the outer wall of the second steel rope are scraped off to prevent the marine organisms from corroding the second steel rope, thereby protecting the second steel rope.

[0069] The automatic locking assembly for winding up includes a rotating ring 414, a first wedge block 415, a second linear drive assembly 421, a transverse connecting plate 422, a fixed side plate 423, a second spring 424, a first side support plate 425 and a second trapezoidal block 426; the other end of the transverse shaft 420 is fixedly mounted with a rotating ring 414, and a plurality of groups of first wedge blocks 415 are evenly fixedly mounted on the circumference of the rotating ring 414, and the second linear drive assembly 421 and the first side support plate 425 are fixedly mounted on the first support frame 45 , the driving end of the second linear drive assembly 421 is fixedly connected to the transverse connecting plate 422, the lower end of the second trapezoidal block 426 is slidably connected to the first side support plate 425, the side wall of the second trapezoidal block 426 is fixedly connected to the fixed side plate 423, and the upper and lower ends of the second spring 424 are respectively fixedly connected to the bottom of the fixed side plate 423 and the top of the first side support plate 425; the height of the transverse connecting plate 422 is higher than the height of the fixed side plate 423, and the fixed side plate 423 is located on the path where the transverse connecting plate 422 moves downward;

[0070] The second linear drive assembly 421 may adopt a commercially available mature cylinder or other structure;

[0071] While lowering the water level of the floating wind power generation platform, the first motor 44 is started to drive the horizontal shaft 420 to rotate clockwise, thereby driving the rotating winding ring 46 and the rotating ring 414 to rotate clockwise, and the rotating winding ring 46 reels the second steel rope 43. At this time, the second linear drive assembly 421 is in a retracted state, and the horizontal connecting plate 422 is not in contact with the fixed side plate 423. The fixed side plate 423 moves upward under the elastic restoring force of the second spring 424, driving the second trapezoidal block 426 to move upward and get stuck between the adjacent first wedge blocks 415; the rotating ring 414 rotates clockwise, driving the first wedge blocks 415 The inclined surface of the first wedge block 415 contacts the upper inclined surface of the second trapezoidal block 426, pushing the second trapezoidal block 426 to move downward along the first side support plate 425, and the rotating ring 414 can rotate smoothly; during the winding process, since the plane of the first wedge block 415 contacts the upper plane of the second trapezoidal block 426 when the first wedge block 415 rotates counterclockwise, it is blocked by the second trapezoidal block 426, so the first wedge block 415 cannot rotate counterclockwise, and then the rotating ring 414, the horizontal shaft 420, and the rotating winding ring 46 cannot rotate counterclockwise, ensuring the stability during the winding process;

[0072] The present invention can always keep the buoy 11, the mounting cylinder 5, the fan cylinder 6 and the like in relatively stable lateral positions, thereby reducing the safety risks caused by lateral deviation.

[0073] While raising the water level of the floating wind power generation platform, the second linear drive assembly 421 is started to extend and drive the horizontal connecting plate 422 to move downward to contact the fixed side plate 423 and push the fixed side plate 423 to move downward, and the fixed side plate 423 drives the second trapezoidal block 426 to move downward and separate from the first wedge block 415, and the first motor 44 is started to drive the horizontal shaft 420 to rotate counterclockwise, thereby driving the rotating winding ring 46 and the rotating ring 414 to rotate counterclockwise, and the rotating winding ring 46 pays out the second steel rope 43;

[0074] A plurality of tensioning components 7 are fixedly mounted on the inner wall of the installation tube 5 to ensure real-time tensioning of the second steel rope 43;

[0075] The tensioning assembly 7 includes a second support wheel 71, a second side support plate 72, a third spring 73 and a slide plate 74; the second side support plate 72 is fixedly mounted on the inner wall of the mounting tube 5, the second side support plate 72 is slidably connected with the slide plate 74, the top of the slide plate 74 is rotatably mounted with the second support wheel 71, the second steel rope 43 passes around the second support wheel 71, the upper and lower ends of the third spring 73 are respectively fixedly connected to the bottom of the second side support plate 72 and the lower end of the slide plate 74, the second steel rope 43 is in contact with the second support wheel 71 and the third spring 73 is always in a stretched state;

[0076] The third spring 73 is in a stretched state, and the elastic restoring force of the third spring 73 drives the slide plate 74 to move upward, and the slide plate 74 drives the second support wheel 71 to move upward and press on the second steel rope 43, so as to achieve the tensioning effect of the second steel rope 43, ensure the stable line-releasing effect, avoid the second steel rope 43 becoming loose due to the excessive line-releasing, and cause the release length of the second steel rope 43 at multiple positions to be inconsistent, so that the buoy 11 is tilted, which is conducive to improving the stability of the line-releasing;

[0077] At the same time, since the second steel rope 43 is in contact with the second supporting wheel 71 and the third spring 73 is always in a stretched state, the third spring 73 has a force to push the slide plate 74 to move upward. When the buoy 11 shakes, the second steel rope 43 becomes loose, and the elastic restoring force of the third spring 73 drives the slide plate 74 to move upward. The slide plate 74 drives the second supporting wheel 71 to move upward and press on the second steel rope 43, which helps the second steel rope 43 to tend to a straight state. The force exerted by the second supporting wheel 71 on the second steel rope 43 is conducive to realizing the restoration of the buoy 11 to a vertical state.

[0078] The second steel rope 43 is provided with a scraping assembly 2 for removing marine organisms such as barnacles on the second steel rope 43 , and the scraping assembly 2 is located below the buoy 11 ;

[0079] The scraping assembly 2 includes a straight hole 21, a counterweight sliding plate 22, a protective cover 23, a winder 24 and a first steel rope 25; the protective cover 23 is fixedly installed at the bottom of the buoy 11, and the winder 24 is fixedly installed inside the protective cover 23. The upper end of the first steel rope 25 is wound on the winder 24, and the lower end of the first steel rope 25 passes through the protective cover 23 and is fixedly connected to the middle part of the counterweight sliding plate 22. The outer ends of multiple cross brackets of the counterweight sliding plate 22 are all provided with straight holes 21 for the second steel ropes 43 to pass through; the aperture of the straight hole 21 is slightly larger than the outer diameter of the second steel rope 43;

[0080] The winder 24 is started regularly to drive the first steel rope 25 to pay out or reel in the wire. The counterweight sliding plate 22 has a certain weight. The first steel rope 25 drives the counterweight sliding plate 22 to move up and down. When the counterweight sliding plate 22 moves, the marine organisms on the outer wall of the second steel rope 43 are scraped off to prevent the marine organisms from corroding the second steel rope 43, thereby protecting the second steel rope 43.

[0081] Embodiment 2: A method for using the wind power generation floating platform with position adjustment function, comprising the following steps:

[0082] 1. When the water level of the floating wind power generation platform needs to be lowered, the water pump 14 is started to suck seawater from the first pipe 12 and then inject it into the buoy 11 through the second pipe 15;

[0083] At the same time, before the first motor 44 is started, the first linear drive assembly 413 is extended to drive the first connecting block 411 to rotate clockwise, and the first connecting block 411 drives the fourth support frame 419 close to the first linear drive assembly 413 to rotate along the third support frame 417 close to the first linear drive assembly 413 in the direction away from the brake pad 427. At the same time, the first connecting block 411 pushes the fourth support frame 419 away from the first linear drive assembly 413 through the connecting rod 49 to rotate along the third support frame 417 away from the first linear drive assembly 413 in the direction away from the brake pad 427. The two fourth support frames 419 respectively drive the arc clamping plate 47 to move outward, so that the fourth support frame 419 drives the arc clamping plate 47 to separate from the brake pad 427 fixed on the horizontal shaft 420; then the first motor 44 is started to drive the horizontal shaft 420 to rotate clockwise, thereby driving the rotating winding ring 46 and the rotating ring 414 to rotate clockwise, and the rotating winding ring 46 and the rotating ring 414 are rotated clockwise. The winding ring 46 reels the second steel rope 43. At this time, the second linear drive assembly 421 is in a retracted state, the horizontal connecting plate 422 is not in contact with the fixed side plate 423, and the fixed side plate 423 moves upward under the elastic restoring force of the second spring 424, driving the second trapezoidal block 426 to move upward and get stuck between the adjacent first wedge blocks 415; the rotating ring 414 rotates to drive the first wedge block 415 to rotate clockwise, and the inclined surface of the first wedge block 415 contacts the upper end inclined surface of the second trapezoidal block 426, pushing the second trapezoidal block 426 to move downward along the first side support plate 425; in the winding process, because the plane of the first wedge block 415 contacts the upper end plane of the second trapezoidal block 426 when the first wedge block 415 rotates counterclockwise, it is blocked by the second trapezoidal block 426, so the first wedge block 415 cannot rotate counterclockwise, thereby making the rotating ring 414, the horizontal shaft 420, and the rotating winding ring 46 unable to rotate counterclockwise;

[0084] Second, when the water level of the floating wind power generation platform needs to be raised, the second linear drive assembly 421 is first started to extend and drive the horizontal connecting plate 422 to move downward to contact the fixed side plate 423 and push the fixed side plate 423 to move downward, and the fixed side plate 423 drives the second trapezoidal block 426 to move downward and separate from the first wedge block 415;

[0085] Then, the water pump 14 is started to suck seawater from the second pipe 15 and then discharged through the first pipe 12, so that the seawater in the buoy 11 is reduced. Due to the increase in buoyancy, the floating platform for wind power generation gradually rises; at the same time, the first motor 44 is started to drive the horizontal axis 420 to rotate counterclockwise, thereby driving the rotating winding ring 46 to rotate counterclockwise to release the line; when releasing the line, the elastic restoring force of the third spring 73 drives the slide plate 74 to move upward, and the slide plate 74 drives the second support wheel 71 to move upward and press on the second steel rope 43, thereby achieving the tensioning effect of the second steel rope 43;

[0086] 3. When the first motor 44 is braked, the first linear drive assembly 413 contracts and drives the first connecting block 411 to rotate counterclockwise, and the first connecting block 411 drives the fourth support frame 419 close to the first linear drive assembly 413 to rotate along the third support frame 417 close to the first linear drive assembly 413 toward the direction close to the brake pad 427. At the same time, the first connecting block 411 pushes the fourth support frame 419 away from the first linear drive assembly 413 to rotate along the third support frame 417 away from the first linear drive assembly 413 toward the direction close to the brake pad 427 through the connecting rod 49. The two fourth support frames 419 respectively drive the arc clamping plates 47 to move inward, so that the fourth support frames 419 drive the arc clamping plates 47 to contact with the brake pad 427 fixed on the horizontal shaft 420, and the two arc clamping plates 47 brake the horizontal shaft 420 to achieve braking of the first motor 44.

[0087] Fourth, the reel 24 is started regularly to drive the first steel rope 25 to pay out or reel in, and the first steel rope 25 drives the counterweight sliding plate 22 to move up and down, and the counterweight sliding plate 22 scrapes the marine life on the outer wall of the second steel rope 43 when moving.
