Description

Technical Field

[0001] This application relates to a wind power installation platform, specifically an offshore wind power installation platform. Background Technology

[0002] Offshore wind power is characterized by abundant resources, high power generation utilization hours, no land occupation, and suitability for large-scale development. It represents the latest frontier in global wind power development and is a key area for renewable energy development. Compared with onshore wind power, offshore wind power has 19%-39% higher energy efficiency. It also has advantages such as no land occupation, high wind speed, less dust, large power generation, stable operation, and zero dust emissions. At the same time, it can reduce the wear and tear of the units and extend the service life of the wind turbine units, making it suitable for large-scale development.

[0003] For the application of small offshore wind turbines, in the patent document "Patent No.: CN205203674U, Patent Name: A Floating Wind Power Foundation", it adopts a regular polygonal structure through buoyancy components and truss components, which has high structural stability and is easy to assemble. It can be quickly designed and assembled according to the power size of the wind power equipment. In order to withstand the strong winds and rain at sea, it is necessary to increase the mass of the offshore wind turbine. However, increasing the mass not only affects the manufacturing cost, but also increases the difficulty and cost of transportation. Moreover, when the wind and rain are strong at sea, the blades of the wind turbine are more susceptible to wind force due to their height, which makes them more prone to damage and affects the service life of the offshore wind turbine. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the height of wind turbine generators can be adjusted using a height-adjusting structure. This allows the height of the wind turbine generators to be lowered during periods of heavy wind and rain at sea, solving the problem that the blades of wind turbine generators are easily damaged in strong winds due to their high height. This reduces the damage caused by wind to the wind turbine generators and increases their service life.

[0005] In order to solve the problems in the existing technology, the position of the barrier plate can be adjusted when the wind is strong, so that the barrier plate is vertical to block the waves and reduce the impact of the waves on the floating plate and other structures. When the wind is weak, the barrier plate is placed horizontally to increase the contact area with the water surface and make the installation platform more stable.

[0006] Furthermore, to address the problems in the existing technology, the position of the float can be adjusted using an extended structure. When the wind is strong, the float can be contracted to reduce the contact area with the water surface, and when the wind is weak or there is no wind, the float can be extended to increase the contact area with the water surface, thereby improving the stability of the installation platform.

[0017] The advantages of this application are:

[0018] 1. This application utilizes a height adjustment structure to freely adjust the height of the wind turbine generator set. When there is heavy wind and rain at sea, the height of the wind turbine generator set can be lowered, thereby lowering the center of gravity of the wind turbine generator set, reducing wind resistance, reducing wind damage to the wind turbine generator set, extending the service life of the wind turbine generator set, and reducing the weight of unnecessary components added to the installation platform to resist strong winds, effectively reducing the production and design costs of the installation platform.

When the wind force is low, any two opposing barrier plates can be adjusted to be vertical to form a wind duct for the installation platform, and the wind duct formed provides a guarantee for the air volume of the wind turbine generator. When the wind force is high, all barrier plates are placed horizontally to increase the contact area between the installation platform and the sea surface, making the installation platform more stable.

[0020] 3. This application utilizes an extension structure to adjust the position of the float. When the wind is strong, the float can be extended to increase the contact area between the installation platform and the sea surface, thereby improving the stability of the installation platform.

[0034] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0036] Reference Figures 1 to 3An offshore wind power installation platform includes a height adjustment structure, comprising a floating plate 1, a support column 2, a support plate 3, a height adjustment plate 4, a height adjustment column 5, a wind turbine generator set 6, a mounting housing 7, a height adjustment motor 8, a first sprocket 9, a height adjustment chain 10, a second sprocket 11, a first height adjustment threaded column 12, and a second height adjustment threaded column 13. The floating plate is located above the support plate 3. The support column 2 is fixedly connected between the floating plate 1 and the support plate 3. The height adjustment plate 4 is slidably connected to the surface of the support column 2. The bottom of the height adjustment column 5 is fixedly located on the side of the height adjustment plate 4 facing the floating plate, and the height adjustment column can slide freely on the support column 2 following the height adjustment plate. The top of the height adjustment column 5 passes through the mounting housing 7, the floating plate 1, and is fixedly connected to the wind turbine generator set 6. The mounting housing 7 is fixedly located on the floating plate. On the side facing away from the support plate 3, and fixedly connected to the top of the inner cavity of the mounting housing 7, a height adjustment motor 8 is fixedly connected to one end of the first height adjustment threaded column 12, and the other end is rotatably mounted on the support plate 3. A second height adjustment threaded column 13 is rotatably mounted between the floating plate 1 and the support plate 3. To ensure a smoother rise or fall of the height adjustment plate, the first height adjustment threaded column 12 and the second height adjustment threaded column 13 are arranged in parallel. Specifically, a first sprocket 9 is fixedly mounted on the first height adjustment threaded column 12, and a first sprocket and a second sprocket 11 are fixedly mounted on the second height adjustment threaded column 13. The first sprocket 9 and the second sprocket 11 are connected by a height adjustment chain 10. The height adjustment plate 4 is threadedly connected to the first height adjustment threaded column 11 and the second height adjustment threaded column 12.

[0037] In order to facilitate the raising and lowering adjustment of the height adjustment column 5, height adjustment holes are provided on the mounting housing 7 and the floating plate 1 respectively for the height adjustment column 5 to pass through; specifically, the height adjustment holes on the mounting housing 7 and the floating plate 1 are on the same axis in the vertical direction, and then the height adjustment column 5 passes through the height adjustment holes in sequence through the floating plate 1 and the mounting housing 7.

[0038] In use, the height adjustment motor 8 starts and drives the first height adjustment threaded column 12 and the first sprocket 9 fixed on the first height adjustment threaded column 12 to rotate. Based on the connection relationship of the height adjustment chain 10, the first sprocket 9 drives the second sprocket 11 to rotate. When the first sprocket 9 and the second sprocket 11 rotate, they can drive the first height adjustment threaded column 12 and the second height adjustment threaded column 13 to rotate. Through the threaded engagement between the first height adjustment threaded column 12, the second height adjustment threaded column 13 and the height adjustment plate 4, the height adjustment plate 4 moves along the support column 2 towards the floating plate 1 or towards the support plate 3, thereby driving the height adjustment column 5 to move in the same direction to pass through or retract the height adjustment hole, and then driving the wind turbine generator 6 to move in the same direction to achieve the rise or fall, thus completing the height adjustment of the wind turbine generator 6. Then, in the case of strong wind weather, the height of the wind turbine generator 6 is lowered, and when the wind is weak or there is no wind, the height of the wind turbine generator 6 is raised to the initial position, increasing the wind resistance and service life of the offshore wind power.

[0039] Through the above technical solutions, the height of the wind turbine generator 6 can be freely adjusted using the height adjustment structure. When there is heavy wind and rain at sea, the height of the wind turbine generator 6 can be lowered to reduce the resistance of the wind turbine generator 6 under strong wind conditions, reduce wind damage to the wind turbine generator 6, and increase the service life of the wind turbine generator 6. The position of the float 41 can be adjusted using the extension structure. When the wind is strong, the float 41 can be retracted to reduce the contact area with the water surface, and when the wind is weak or there is no wind, the float 41 can be extended to increase the contact area with the water surface and improve the stability of the installation platform.

[0040] A central control unit is installed on the floating board 1. The central control unit is electrically connected to the wind turbine generator 6, the elevation motor 8, the first receiver / discharge motor 24, the second receiver / discharge motor 32, and the extension motor 44. The central control unit is also equipped with a wind speed sensor to detect the wind speed at sea. The central control unit controls the operation of the elevation motor 8, the first receiver / discharge motor 24, the second receiver / discharge motor 32, and the extension motor 44 according to the detected wind speed. The floating board 1 is connected to the seabed by anchor bolts or anchor cables.

[0041] Specifically, such as Figure 2 As shown, the wind turbine generator set 6 consists of a power generation component, blades, a tower and a base. The tower is fixed to the top of the base, and the power generation component is installed on the top of the tower. Blades are installed on one side of the power generation component. The diameter of the base is larger than the diameter of the height adjustment column 5. When the wind turbine generator set 6 descends, the base contacts the top surface of the floating plate 1, and the floating plate 1 supports the wind turbine generator set 6.

[0042] Specifically, such as Figure 2 and Figure 4 As shown, several support columns 2 are rectangularly distributed on the support plate 3, while the height adjustment plate 4 is provided with several limiting holes, and the number of limiting holes corresponds one-to-one with the number of support columns 2. In this embodiment, for ease of explanation, four support columns 2 are selected and fixed on the support plate 3 in a rectangular structure. Four limiting holes in a rectangular structure are provided on the height adjustment plate 4, and the number and position of the limiting holes correspond one-to-one with the number and position of the support columns 2. Furthermore, the height adjustment plate and the support columns 2 slide together, and the support columns 2 can limit the movement trajectory of the height adjustment plate 4.

[0043] Preferably, two symmetrically distributed rotating holes are provided on the floating plate 1, and two threaded holes are provided on the height adjustment plate 4 corresponding to the rotating hole positions. The first height adjustment threaded post 12 and the second height adjustment threaded post 13 are rotatably connected to the rotating holes and threadedly engaged with the threaded holes. The floating plate 1 is provided with a height adjustment port on the mounting housing 7, and the top of the height adjustment post 5 passes through the height adjustment port and rises above the floating plate 1.

[0044] As a further optimization scheme, such as Figure 2 and Figure 5 As shown, the height adjustment structure includes multiple sets of support components, a transmission chain 15, and a support motor 16. Multiple accommodating cavities are arranged in a circular array on the floating plate 1, and the number of support components corresponds one-to-one with the number of accommodating cavities. Specifically, each support component includes a transmission sprocket 14, a rotating shaft 17, and a reinforcing plate 18. The rotating shaft 17 is rotatably disposed within the accommodating cavity, while the transmission sprocket 14 is fixedly connected to the rotating shaft 17. The reinforcing plate 18 is fixed to the end of the rotating shaft 17 away from the accommodating cavity. Multiple transmission sprockets 14 are connected by a transmission chain 15. To reduce design costs, multiple transmission sprockets can share a single support motor 16, and the support motor 16 is located in the accommodating cavity where the rotating shaft is connected. In specific implementation, there can be one or more support motors 16, or they can be arranged one-to-one with the number of rotating shafts 17. It is worth noting that when the support motors 16 are arranged one-to-one with the rotating shafts, the assembly of the transmission sprockets 14 and the transmission chain 15 can be omitted.

[0045] To form a stable support, the rotation direction and rotation speed of the multiple reinforcing plates 18 are the same; thereby completing the locking support or unlocking; and to ensure the stability of the support of the reinforcing plates 18, the distance between the reinforcing plates 18 and the bottom surface of the floating plate 1 is greater than the thickness of the height adjustment plate 4.

[0046] With the above technical solution, when the wind turbine generator set 6 rises to its highest position, the height adjustment plate 4 is also at its highest position. At this time, the support motor 16 drives the corresponding rotating shaft 17 and the transmission sprocket 14 located on the rotating shaft 17 to rotate. Based on the relationship between the multiple transmission sprockets 1 and the transmission chain 15, the other transmission sprockets 14 are driven to rotate. Thus, when the transmission sprocket 14 rotates, it can drive the reinforcing plate 18 to rotate, so that the reinforcing plate 18 rotates to the bottom of the height adjustment plate 4. The reinforcing plate 18 forms an auxiliary support for the bottom of the height adjustment plate 4, reducing the weight of the height adjustment threaded column 13, reducing the wear of the height adjustment threaded column 13, and increasing the service life of the height adjustment threaded column 13.

[0047] As an optimization solution, such as Figure 2 , Figure 3 and Figure 6As shown, the installation platform also includes a reinforcement mechanism, which comprises a blocking structure. The blocking structure includes a fixed frame 19, an annular float 20, and multiple sets of blocking components. To enhance the stability of the blocking structure, one end of the fixed frame 19 is fixedly connected to the inner wall of the annular float 20 in a circular array, while the other end is fixedly connected to the floating plate 1. The blocking components are placed on the fixed frame 19, and the number of blocking components corresponds one-to-one with the number of fixed frames 19. Specifically, each set of blocking components includes a central column 21 and at least two side... The device includes a side ear 22, a baffle plate 23, a first take-up and release motor 32, and a take-up and release line 35. The two side ears 22 are fixedly installed on the top of the floating plate 1. The two ends of the central column 21 are fixedly connected to the side ears 22. The baffle plate 23 is rotatably connected to the central column 21. One end of the take-up and release line 35 is fixedly connected to the end of the baffle plate 23 away from the central column 21, and the other end is wound around the output end of the first take-up and release motor 32. In order to facilitate the winding of the take-up and release line 35, a first take-up and release shaft 33 is also fixedly connected to the output end of the first take-up and release motor 32.

[0048] In use, the first take-up and release motor 32 is started, and the output end of the first take-up and release motor 32 will be linked to the rotation of the first take-up and release shaft. Based on the winding relationship between the take-up and release line 35 and the first take-up and release shaft 33, when the first take-up and release shaft rotates, the take-up and release line 35 will be wound onto or unwound from the first take-up and release shaft 33. Furthermore, through the fixed connection between the take-up and release line and the baffle plate 23, when the first take-up and release shaft 33 winds up the take-up and release line 35, the take-up and release line will pull the baffle plate 23 to rotate relative to the center post 21 to move away from the fixed frame 19 and adjust it to an upright state. When the first take-up and release shaft 33 unwinds the wound take-up and release line 35, the baffle plate 23 will rotate relative to the center post 21 to move closer to the fixed frame 19 and adjust it to a flat state.

[0049] It is worth noting that the first take-up and release motor 32 is operated through a separate control module. When there are no waves on the sea surface, the control module controls any two opposing first take-up and release motors 32 to start, winding up the take-up and release line 35 to adjust the baffle plate 23 corresponding to the first take-up and release motor 32 to an upright position. Then, the two opposing baffle plates 23 will be adjusted to form a wind duct, guiding the wind at sea and supplementing the wind volume for the wind turbine's power generation. Furthermore, the two baffle plates 23 used to form the wind duct can be selected according to the actual situation, such as... Figure 1As shown, taking the blades of the wind turbine generator set 6 as a reference, two baffle plates 23 in the front-to-back direction of the blades of the wind turbine generator set 6 can be selected, or two baffle plates 23 in the left-to-right direction of the blades of the wind turbine generator set 6 can be selected; when the sea waves are large, the control module controls all the first take-up motors 32 to start, and unfolds the take-up and release lines 35 to adjust all the baffle plates 23 to a flat state. When all the baffle plates 23 are adjusted horizontally, the contact area between the wind power installation platform and the water surface can be greatly increased, thereby making the operation of the wind power installation platform more stable; specifically, the control module is a single-chip microcomputer commonly found in the market.

[0050] As an optimization solution, such as Figure 2 , Figure 7 and Figure 8 As shown, the reinforcement mechanism also includes multiple sets of positioning components, with the number of positioning components corresponding one-to-one with the fixed frame 19. Each positioning component includes a second receiver / discharge motor 24, a first bevel gear 25, a second bevel gear 26, a second threaded post 27, a movable plate 28, a connecting rod 29, and a limiting ball 30. The annular float 20 has a mounting cavity corresponding to the position of the fixed frame 19. The second receiver / discharge motor 24 is fixedly connected to the mounting cavity of the annular float 20, and the output end of the second receiver / discharge motor 24 is fixedly connected to the first bevel gear 25. Furthermore, the second threaded post 27 is rotatably mounted in the fixed frame 19, and the second bevel gear 26 is fixedly connected to the end of the second threaded post 27 facing the second receiver / discharge motor 24. To facilitate the... A bevel gear 25 meshes with a second bevel gear 26. A through hole is provided on the side where the fixed frame 19 and the annular float 20 are connected, that is, the first bevel gear 25 passes through the through hole and meshes with the second bevel gear 26. Furthermore, an internal thread adapted to the second threaded post 27 is provided on the movable plate 28. The movable plate 28 is threadedly connected to the second threaded post 27. A first sliding opening is provided on the fixed frame 19. The blocking plate is positioned in the sliding groove corresponding to the first sliding opening. The limiting ball 30 is located in the sliding groove and slides and engages with the sliding groove. The movable template 28 is fixedly connected to the limiting ball 30 through the connecting rod 29. It is worth noting that the end of the sliding groove facing the side ear 22 is also provided with an opening, and the size of the limiting ball is adapted to the opening.

[0051] Through the above technical solution, in use, the second retractor 24 drives the first bevel gear 25 to rotate, thereby driving the second bevel gear 26 to rotate, which in turn drives the second threaded column 27 to rotate. When the second threaded column 27 rotates, it can drive the moving plate 28 to move, which in turn drives the connecting rod 29 to move in the same direction, thereby driving the limiting ball 30 to move in the sliding groove of the fixed frame 19 toward the opening. When the limiting ball 30 moves to the opening, the limiting ball 30 can freely exit from the opening to release the lock on the blocking plate 23. The first retractor 32 then winds up and unwinds the rope 35 to pull up the blocking plate 23 and adjust it to a vertical state; When the first retractor 32 extends the retractor rope 35, the vertically positioned blocking plate 23 can be adjusted to a flat position. When the blocking plate 23 is adjusted to a flat position, the limiting ball 30 will re-enter the sliding groove from the opening. Then, the second retractor 24 drives the first bevel gear 25 to rotate, which in turn drives the second bevel gear 26 to rotate, which in turn drives the second threaded column 27 to rotate. When the second threaded column 27 rotates, it can drive the moving plate 28 to move. At this time, it can drive the connecting rod 29 to move in the same direction, thereby driving the limiting ball 30 to move away from the opening direction in the sliding groove of the fixed frame 19, so as to lock the blocking plate 23.

[0052] Specifically, the state of the blocking plate 23 can be freely switched and adjusted using the blocking structure. When the wind force at sea is small, any two opposing blocking plates 23 can be adjusted to be vertical to form a wind duct for the installation platform and to ensure the air volume of the wind turbine generator through the formed wind duct. When the wind force is large, all blocking plates are placed horizontally to increase the contact area between the installation platform and the sea surface, making the installation platform more stable.

[0053] In some cases, the blocking structure also includes a first spring 36, one end of which is fixedly connected to the side of the blocking plate 23 facing away from the take-up and release line 35, and the other end is fixedly connected to the side of the fixing frame 19 facing the blocking plate 23. In use, when the first take-up and release motor 32 extends the take-up and release line 35, the blocking plate 23 will move closer to the fixing frame 19 under the elastic force of the first spring 36 based on its rotational connection with the center column 21 and be adjusted to be horizontal.

[0054] As an optimization solution, such as Figure 2 , Figure 3 and Figure 10As shown, the installation platform also includes multiple sets of extension structures. Each extension structure includes a reinforcing sleeve 37, a second spring 38, a sliding block 39, a connecting plate 40, a float 41, an extension rope 42, and an extension motor 44. To improve the stability of the connection and the balance of forces, the reinforcing sleeve 37 and the outer wall of the annular float 20 are arranged in a ring array. The second spring 38 and the sliding block 39 are both movably disposed inside the reinforcing sleeve 37. One end of the second spring 38 is fixedly connected to the bottom wall of the reinforcing sleeve 37, and the other end is fixedly connected to the sliding block 39. The float 41... 41 is movably sleeved on the outer wall of the reinforcing sleeve 37, and the sliding block 39 is fixedly connected to the float 41 through the connecting plate 40. The reinforcing sleeve 37 is also provided with a second sliding opening for the connecting plate 40 to slide. That is, when the sliding block 39 slides inside the reinforcing sleeve 37, the sliding block 39 will slide along the float 41 through the connecting plate 40. Specifically, the extension motor 44 is fixedly set at the top of the annular float 20 corresponding to the position of the reinforcing sleeve 37, and one end of the extension rope 42 is fixedly connected to the float 41, and the other end is wound around the output shaft of the extension motor 44.

[0055] When the extension motor 44 is started, the output shaft of the extension motor 44 will either wind up or unwind the extension rope 42. When the extension motor 44 winds up the extension rope 42, the float 41 will move towards the annular float 20 on the reinforcing sleeve 37 under the action of the extension rope 42 and move closer to it. When the extension motor 44 unwinds the extension rope 42, the float 41 will move away from the annular float 20 on the reinforcing sleeve 37 under the action of the second spring 38 and move away from it.

[0056] In some cases, to facilitate the winding of the extension rope 42, the extension structure is also provided with a second take-up and release shaft 43. The second take-up and release shaft 43 is fixedly connected to the output shaft of the extension motor 44. In order to make the second take-up and release shaft run smoothly, a limiting plate 45 is provided at the position of the second take-up and release shaft 43. That is, the end of the second take-up and release shaft away from the extension motor 44 is rotatably connected to the limiting plate 45. The extension rope 42 is wound around the second take-up and release shaft 43.

[0057] With the above technical solution, in normal weather conditions, the extension motor 44 can drive the second retraction shaft 43 to rotate, and the second retraction shaft 43 can be used to rewind the extension rope 42, thereby driving the float 41 to move along the reinforcing sleeve 37 and retracting the reinforcing sleeve 37; when the wind is strong, the second retraction shaft 43 releases the extension rope 42, and at this time, under the action of the second spring 38, the float 41 returns to its initial position, that is, the float 41 is unfolded, increasing the contact area between the installation platform and the sea surface and improving the stability of the installation platform operation.

[0058] Specifically, an anti-detachment plate is fixedly connected to the end of the reinforcing sleeve 37 away from the fixed frame 19; the anti-detachment plate blocks the float 41 that is movably set on the reinforcing sleeve 37 to prevent the float 41 from detaching from the reinforcing sleeve 37.
