Description

Technical Field

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

[0002] Offshore wind power is the fastest-growing green energy technology. While onshore wind farm construction is rapidly developing, people have noticed some limitations to onshore wind energy utilization, such as large land area requirements and noise pollution. Due to the abundant offshore wind energy resources and the feasibility of current technology, the ocean is poised to become a rapidly developing wind power market.

[0003] The main types of offshore wind power generation are: 1. Intertidal and subtidal mudflat wind farms, which refer to wind farms developed and constructed in sea areas below the long-term average high tide line along the coast and within a water depth of 5m below the theoretical lowest tide level; 2. Nearshore wind farms, which refer to wind farms developed and constructed in sea areas with a water depth of 5m to 50m below the theoretical lowest tide level, including wind farms developed and constructed on islands and reefs without fixed residents in the corresponding developed sea areas; 3. Deep-sea wind farms, which refer to wind farms developed and constructed in sea areas with a water depth greater than 50m below the theoretical lowest tide level, including wind farms developed and constructed on islands and reefs without fixed residents in the corresponding developed sea areas.

[0004] As a type of deep-sea wind farm, a semi-submersible offshore wind turbine is a type of wind turbine that is placed underwater and supported by water depth and buoyancy, thereby reducing the impact of wind on the turbine and improving power generation efficiency and stability. However, a semi-submersible offshore wind turbine still requires a towing rope to ensure its position and stability, especially during the construction, installation, and maintenance of the device. When the semi-submersible offshore wind turbine is generating electricity, it needs to be towed by a towing rope to ensure the position and stability of the device. Since the semi-submersible offshore wind turbine is located in a deep-sea area and the towing rope is used when submerged in the seawater, a large number of shellfish will attach to the towing rope. The shellfish attached to the towing rope will cause wear and corrosion to the towing rope, reducing the strength of the towing rope, and may cause the towing rope to break or fail, which is not conducive to the stable operation of the offshore wind turbine.

A plurality of traction components for pulling the floating platform 101 are arranged below the floating platform 101. The traction component includes an L-shaped frame 201 fixed to the lower end of the floating platform 101. A traction rope 202 is slidably connected to the L-shaped frame 201. One end of the traction rope 202 is fixed to the seabed. A circular plate 3 is arranged below the floating platform 101. The floating platform 101 is provided with a lifting component for lifting the circular plate 3 and a guide component for guiding the circular plate during the lifting process. The circular plate 3 There are multiple groups of buffer components provided on it, which are respectively used to buffer and connect with each traction rope 202. Each traction rope 202 is provided with an annular plate 8 on its outer sleeve. The lower end of the annular plate 8 is provided with a cleaning component for cleaning shellfish attached to the surface of the traction rope 202. A driving component for making the annular plate 8 slide along the outer side of the traction rope 202 is provided above the annular plate 8. During the power generation operation of the offshore wind power generation device, the cleaning component is used to automatically scrape and clean the shellfish on the surface of the traction rope 202, so as to prevent the shellfish on the surface of the traction rope 202 from affecting the stable power generation operation of the offshore wind power generation device.

[0029] Specifically, multiple groups of cleaning components are provided, and the multiple groups of cleaning components are arranged in a circular array around the traction rope 202; the cleaning effect is guaranteed by the multiple groups of cleaning components.

[0030] Specifically, the cleaning component includes a first mounting plate 901 arranged below the annular plate 8, a connecting component for connecting the first mounting plate 901 is provided between the annular plate 8 and the first mounting plate 901, one side of the first mounting plate 901 is connected to a scraper 902 through a pushing component, and an arc groove 903 is provided on one side of the scraper 902; the pushing component includes a plurality of first sleeves 1101 fixed to the first mounting plate 901, each first sleeve 1101 is slidably connected to a first slide rod 1102, one end of each first slide rod 1102 is fixed to one side of the scraper 902, and the outer side of each first sleeve 1101 is provided with a first spring 1103, and both ends of the first spring 1103 They are respectively against the scraper 902 and the first mounting plate 901, and the arc groove 903 on the scraper 902 is set against the outer side of the traction rope 202 under the elastic force of the first spring 1103; during the sliding of the annular plate 8, the scraper 902 is driven to move downward through the connection between the connecting component and the pushing component, and during the downward movement of the scraper 902, the elastic force of each first spring 1103 on the pushing component is used to keep the arc groove 903 of the scraper 902 against the outer side of the traction rope 202, and the shellfish on the surface of the traction rope 202 are scraped and cleaned, so as to prevent the shellfish on the surface of the traction rope 202 from affecting the stable power generation operation of the offshore wind power generation device.

[0031] Specifically, the connecting assembly includes a plurality of second sleeves 1001 fixed to the upper end of the first mounting plate 901, each second sleeve 1001 is slidably connected to a second slide bar 1002, one end of each second slide bar 1002 is fixed to the annular plate 8, and a second spring 1003 is sleeved on the outer side of each second sleeve 1001; in the process of cleaning the shellfish outside the traction rope 202 by sliding the scraper 902, when the shellfish is tightly adsorbed and the scraper 902 cannot directly push it apart, the shellfish is removed by the scraper 902. The opposing limiting effect on the scraper 902 and the continued movement of the annular plate 8 cause the annular plate 8 to move toward the scraper 902. During the movement, each second slide bar 1002 is pushed to slide on each second sleeve 1001 respectively, and the second spring 1003 is deformed by force to generate elastic force. The elastic force of the second spring 1003 on the first mounting plate 901 and the scraper 902 is increased, thereby increasing the pushing force of the scraper 902 on the opposing shellfish, and further improving the effect of cleaning the shellfish on the traction rope 202.

[0032] Specifically, the driving assembly includes a plurality of first mounting frames 1201 fixed to the upper end of the annular plate 8, and each first mounting frame 1201 is arranged in a circular array around the traction rope 202. A rubber wheel 1202 is rotatably connected to the first mounting frame 1201, and the rubber wheel 1202 is arranged to abut against the outer side of the traction rope 202. A first motor 1203 for driving the rubber wheel 1202 to rotate is installed on the first mounting frame 1201; the rubber wheel 1202 is driven to rotate by the first motor 1203. Since the rubber wheel 1202 abuts against the outer side of the traction rope 202, during the rotation of the rubber wheel 1202, the friction between the rubber wheel 1202 and the outer side of the traction rope 202 causes the annular plate 8 to slide on the outer side of the traction rope 202.

[0033] Specifically, the lifting assembly includes a second mounting plate 401 provided on the floating platform 101, a plurality of connecting rods 402 are fixed on the second mounting plate 401, and the second mounting plate 401 is connected and fixed to the floating platform 101 under the connection of each connecting rod 402, a threaded tube 403 is rotatably connected to the second mounting plate 401, a threaded rod 404 is threadedly engaged with the threaded tube 403, one end of the threaded rod 404 is fixed to the upper end of the circular plate 3, and a second motor 405 for driving the threaded tube 403 is installed on the second mounting plate 401; the guide assembly includes a screw threaded tube 403 fixed on the second mounting plate The third sleeve 501 at the lower end of 401 is slidably connected to the third slide rod 502, and one end of the third slide rod 502 is fixed to the upper end of the circular plate 3; the second motor 405 is started, and the threaded tube 403 is driven to rotate by the second motor 405. During the rotation of the threaded tube 403, the threaded tube 403 and the threaded rod 404 are engaged with each other to drive the circular plate 3 to move under force. During the movement of the circular plate 3, the third sleeve 501 and the third slide rod 502 slide and guide the moving circular plate 3, so that the circular plate 3 is lifted and lowered.

[0034] Specifically, the buffer assembly includes a sleeve 601 fixed to the outside of the circular plate 3, a slide plate 602 is slidably connected to the sleeve 601, the slide plate 602 and the interior of the sleeve 601 are matched with each other, a plurality of damping holes 603 are provided on the slide plate 602, the interior of the sleeve 601 is filled with damping fluid, one end of the traction rope 202 passes through the interior of the sleeve 601 and is fixed to the slide plate 602, and the interior of the sleeve 601 is provided with a third spring 604 for connecting with the slide plate 602; a support assembly for supporting the traction rope 202 is provided on the L-shaped frame 201; after the installation, fixation and traction of each traction rope 202 are completed, the traction rope 202 is released through the launch device above the floating platform 101. The electrical component 102 performs power generation operations. During the power generation process, due to the action of the water flow below the water area, the traction rope 202 is driven to swing under force. During the swinging of the traction rope 202, the traction rope 202 pulls the slide plate 602 to slide inside the sleeve 601. During the sliding of the slide plate 602 inside the sleeve 601, the damping fluid inside the sleeve 601 passes through the various damping holes 603 of the slide plate 602, generating a damping mechanism to cushion the swing of the traction rope 202 after being subjected to force, thereby reducing the swing amplitude of the traction rope 202, and further facilitating more stable operation of the floating platform 101 and the power generation component 102 on the floating platform 101.

[0035] Specifically, the support assembly includes a second mounting frame 701 fixed on the L-shaped frame 201, and the second mounting frame 701 is rotatably connected to a mounting shaft 702, and a support roller 703 is fixed on the mounting shaft 702 for counteracting the inner support of the traction rope 202; the traction rope 202 is supported by the support roller 703 on the mounting shaft 702, which facilitates more stable use of the traction rope 202, and reduces the wear of the traction rope 202 during use by supporting the traction rope 202.

[0036] Working principle: When the offshore wind power generation device is in operation, the floating platform 101 is moved to the desired position. After the floating platform 101 is moved, one end of each traction rope 202 is pulled to fix one end of each traction rope 202 to the seabed. After one end of each traction rope 202 is fixed to the seabed, the second motor 405 is started, and the threaded tube 403 is driven to rotate by the second motor 405. During the rotation of the threaded tube 403, the mutual engagement transmission between the threaded tube 403 and the threaded rod 404 drives the circular plate 3 to move under force. During the movement of the circular plate 3 The third sleeve 501 and the third slide bar 502 provide sliding guidance for the moving circular plate 3, causing the circular plate 3 to move downward. During the downward movement of the circular plate 3, the connection between the various components on the buffer assembly pulls one end of the traction rope 202. Since one end of the traction rope 202 is fixed to the seabed, the traction rope 202 is tightened during the pulling process. By tightening the traction ropes 202, the floating platform 101 is pulled after moving, so that the power generation assembly 102 on the floating platform 101 can perform offshore power generation operations more stably.

[0037] After the installation, fixation and traction of each traction rope 202 are completed, power generation operation is carried out through the power generation component 102 above the floating platform 101. During the power generation process, due to the action of the water flow below the water area, the traction rope 202 is driven to swing under force. During the swinging of the traction rope 202, the slide plate 602 is pulled by the traction rope 202 to slide inside the sleeve 601. During the sliding of the slide plate 602 inside the sleeve 601, the damping fluid inside the sleeve 601 passes through the various damping holes 603 of the slide plate 602, generating a damping mechanism to cushion the swing of the traction rope 202 after being stressed, reduce the swing amplitude of the traction rope 202, and further facilitate the more stable operation of the floating platform 101 and the power generation component 102 on the floating platform 101.

[0038] During the power generation operation, as the traction rope 202 is pulled, a large number of shellfish will adhere to the surface of the traction rope 202, and the shellfish on the surface of the traction rope 202 are cleaned by the cleaning component; during the cleaning process, the rubber wheel 1202 is driven to rotate by the first motor 1203. Because the rubber wheel 1202 is against the outer side of the traction rope 202, during the rotation of the rubber wheel 1202, the friction between the rubber wheel 1202 and the outer side of the traction rope 202 causes the annular plate 8 to slide on the outer side of the traction rope 202. During the sliding of the annular plate 8, the connection between the connecting component and the pushing component drives the scraper 902 to move downward, and during the downward movement of the scraper 902, the elastic force of each first spring 1103 on the pushing component causes the arc groove 903 of the scraper 902 to remain against the outer side of the traction rope 202. The shellfish on the surface of the traction rope 202 are scraped and cleaned to prevent the shellfish on the surface of the traction rope 202 from affecting the stable power generation operation of the offshore wind power generation device. In the process of cleaning the shellfish on the outside of the traction rope 202 by sliding the scraper 902, when the shellfish are tightly adsorbed and the scraper 902 cannot directly push them apart, the shellfish acts on the scraper 902 to limit the impact and the annular plate 8 continues to move, so that the annular plate 8 moves toward the scraper 902. During the movement, each second sliding rod 1002 is pushed to slide on each second sleeve 1001 respectively, and the second spring 1003 is deformed by force to generate elastic force. The elastic force of the second spring 1003 on the first mounting plate 901 and the scraper 902 is increased, thereby further improving the effect of cleaning the shellfish on the traction rope 202.
