Description

Technical Field

[0001] This invention belongs to the field of wind turbine blade hoisting technology, specifically relating to an anti-collision wind turbine hoisting device and hoisting method. Background Technology

[0002] With the global trend towards a cleaner and more sustainable energy structure, wind energy, as a pollution-free and abundant renewable energy source, has been widely developed and applied. Among them, offshore wind power, with its unique advantages such as not occupying land resources, stable wind speed, high power generation efficiency, and small environmental impact, has become an important development direction for the wind power industry. Countries around the world are increasing their investment in offshore wind power projects and promoting the large-scale deployment of offshore wind turbines.

[0003] As the core component of wind turbines, the size and weight of wind turbine blades increase with the improvement of power generation. This places extremely high technical requirements on the blade hoisting operation. Since the offshore operating environment is significantly affected by wind and waves, random changes in wind speed and direction can cause unstable movements such as horizontal rotation and swaying of the blades, which will increase the risk of attitude loss during hoisting. Furthermore, during the blade position adjustment, the center of gravity of the hoisting system will dynamically shift. If the center of gravity balance adjustment is not carried out in time, it will cause the hoisting frame to tilt, which will not only affect the hoisting accuracy, but may also cause the hoisting equipment to become unstable and threaten the safety of the operation. Summary of the Invention

[0004] The purpose of this invention is to provide a lifting device with a simple structure and reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] This invention provides an anti-collision wind turbine hoisting device, including a hoisting frame and slings. The surface of the hoisting frame near both ends is provided with support bars. The slings are connected to the support bars. The hoisting frame is provided with multiple sets of connecting frames and hoisting clamps corresponding to the multiple sets of connecting frames. The multiple sets of connecting frames are located between two sets of support bars. The hoisting clamps are used to hold the blades of the wind turbine.

[0007] Multiple sets of connecting frames consist of fixed frames and adjusting frames. The fixed frames are symmetrically arranged and fixedly sleeved on the surface of the lifting frame. The adjusting frames are arranged between two sets of fixed frames and slidably sleeved on the surface of the lifting frame. Moving the adjusting frames drives the corresponding connected lifting clamps to move to adjust the blade position.

[0008] The hoisting frame is equipped with a center of gravity adjustment mechanism for balancing the hoisting frame. The center of gravity adjustment mechanism includes adjustment boxes connected to both ends of the hoisting frame. The adjustment boxes contain a flowable medium. The hoisting frame has a conveying channel inside. The two ends of the conveying channel are respectively connected to the interior of two sets of adjustment boxes. The conveying channel is equipped with a conveying mechanism that conveys the medium in the two sets of adjustment boxes to each other to adjust the center of gravity of the hoisting frame after clamping the blade.

[0009] As a further optimization of the present invention, the upper surface of the hoisting frame is provided with a sliding groove, and the inner wall of the adjusting frame is rotatably connected with a roller, which rolls along the inside of the sliding groove.

[0010] As a further optimization of the present invention, each set of support bars consists of two sets of short bars, and the two sets of short bars in each set of support bars are respectively connected to the corresponding two sides of the lifting frame, and the sling is connected to the surface of the four sets of short bars away from the lifting frame.

[0011] As a further optimization of the present invention, a drive mechanism is connected to the hoisting frame for driving the adjustment frame to move along the surface of the hoisting frame. The drive mechanism includes a rotary motor. The surface of the hoisting frame is provided with toothed grooves. An adjustment plate is connected between the two sets of adjustment frames. The rotary motor is connected to the surface of the adjustment plate. A gear that meshes with the toothed grooves is fixedly connected to the drive end of the rotary motor.

[0012] As a further optimization of the present invention, the flowable medium is sand particles.

[0013] As a further optimization of the present invention, the two sets of adjustment boxes are a left box and a right box, respectively. The conveying mechanism includes a drive motor and a spiral conveying roller. The drive motor is connected to the surface of the left box away from the lifting frame. The drive end of the drive motor extends into the interior of the left box and is connected to one end of the spiral conveying roller. The other end of the spiral conveying roller extends through the conveying channel into the right box and is rotatably connected to the inner wall of the right box.

[0014] As a further optimization of the present invention, both sets of fixing frames are equipped with fans.

[0015] As a further optimization of the present invention, the lifting clamp includes a driving component, an upper clamping plate shell, and a lower clamping plate shell. Inner clamping plates are fixedly connected to corresponding side surfaces of the upper and lower clamping plate shells. The side surface of the upper clamping plate shell away from the inner clamping plate is connected to a corresponding connecting frame. An upper mounting groove is formed on the surface of the upper clamping plate shell, and a lower mounting groove is formed on the surface of the lower clamping plate shell. The end of the lower clamping plate shell away from the inner clamping plate is rotatably connected to the end of the upper clamping plate away from the inner clamping plate. The non-driving end of the driving component is rotatably connected to the corresponding connecting frame. The driving end of the driving component extends through the upper mounting groove into the lower mounting groove and is rotatably connected to the inner wall of the lower mounting groove.

[0016] As a further optimization of the present invention, airbags are connected to the corresponding two sides of the two sets of inner clamping plates. An air pump is connected to the surface of the lifting frame. An air pump outlet is connected to an air pipe corresponding to the lifting frame. The end of each set of air pipes away from the air pump passes through the corresponding lifting clamp and communicates with the airbag. A solenoid valve is installed on the end of each set of air pipes near the air pump, and a hydraulic valve is installed on the end of each set of air pipes away from the air pump.

[0017] A second aspect of the present invention provides a method for hoisting an anti-collision wind turbine, implemented by the anti-collision wind turbine hoisting device provided above, comprising the following steps:

[0018] S1. Suspend the hoisting frame on the lifting equipment with slings, so that multiple sets of hoisting clamps correspond to the blades to be clamped.

[0019] S2. Start the air pump to inflate the airbag through the air inflator. After the airbag is inflated, start the hoisting clamp and work with the airbag to clamp the blades.

[0020] S3. If the blade position needs to be adjusted, first start the lifting clamp connected to the fixed frame to loosen the blade, then start the drive mechanism to drive the adjustment frame to move in the direction required to adjust the blade, and finally make the lifting clamp connected to the fixed frame clamp the blade to complete the blade position adjustment.

[0021] S4. After the blade position is adjusted, if the lifting frame tilts, start the drive motor and use the spiral conveyor roller to transport the flowable medium in the lower side adjustment box to the higher side adjustment box until the lifting frame is horizontally balanced.

[0022] S5. When the blades rotate horizontally in windy weather, turn on the fan on the corresponding side of the fixed bracket according to the direction of blade rotation, and adjust the blades to maintain stability by controlling the wind force.

[0023] S6. After the blade is hoisted to the designated position, the hoisting clamp removes the blade, completing the hoisting process.

[0024] The beneficial effects of this invention are as follows: This invention uses a fixed frame and a sliding adjustment frame in conjunction with corresponding lifting clamps to hold the blades in groups. When adjusting the blade position, it is only necessary to switch the tightness of the groups to drive the adjustment frame to move the blades. At the same time, a center of gravity adjustment mechanism is set up to realize the bidirectional transport of the flowable medium in the adjustment box through the conveying mechanism. When the center of gravity shifts during blade position adjustment or lifting, the medium can be quickly transported to the higher side of the adjustment box, so as to balance the center of gravity of the lifting frame in time, avoid blade tilting, significantly improve the stability of the lifting process, and reduce the risk of collision.

[0033] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Example 1;

[0035] like Figure 1 and Figure 4 As shown, an anti-collision wind turbine hoisting device includes a hoisting frame 1 and slings 2. Support bars 3 are provided on the surfaces of the hoisting frame 1 near both ends. The slings 2 are connected to the support bars 3. The hoisting frame 1 is provided with multiple sets of connecting frames 4 and hoisting clamps 5 corresponding to the multiple sets of connecting frames 4. The multiple sets of connecting frames 4 are all located between two sets of support bars 3. The hoisting clamps 5 are used to clamp the blades of the wind turbine.

[0036] The multiple sets of connecting frames 4 consist of fixed frames 41 and adjusting frames 42. The fixed frames 41 are symmetrically arranged and fixedly sleeved on the surface of the lifting frame 1. The adjusting frames 42 are arranged between the two sets of fixed frames 41 and are slidably sleeved on the surface of the lifting frame 1. Moving the adjusting frames 42 drives the corresponding connected lifting clamps 5 to move to adjust the blade position.

[0037] The hoisting frame 1 is equipped with a center of gravity adjustment mechanism 6 for balancing the hoisting frame 1. The center of gravity adjustment mechanism 6 includes adjustment boxes connected to both ends of the hoisting frame 1. The adjustment boxes contain a flowable medium. The hoisting frame 1 has a conveying channel 7 inside. The two ends of the conveying channel 7 are respectively connected to the inside of two sets of adjustment boxes. The conveying channel 7 is equipped with a conveying mechanism 9. The conveying mechanism 9 conveys the medium in the two sets of adjustment boxes to each other to adjust the center of gravity of the hoisting frame 1 after clamping the blade.

[0038] It should be noted that multiple sets of adjustment frames 42 can be provided. In this embodiment, two sets of adjustment frames 42 are provided. The adjustment frames 42, together with the corresponding lifting clamps 5, make slight adjustments to the position of the blades.

[0039] In practical use, when the blade needs to be moved to one side after multiple sets of lifting clamps 5 have clamped the blade, first activate the two sets of lifting clamps 5 connected to the fixed frame 41 to release the blade (at this time, the two sets of lifting clamps 5 connected to the adjusting frame 42 should be in the state of clamping the blade). Then move the adjusting frame 42 in the direction where the blade needs to be moved, and then make the two sets of lifting clamps 5 connected to the fixed frame 41 clamp the blade. The blade position adjustment can be completed. However, after the blade position is adjusted, the center of gravity of the entire device will change, causing the blade to tilt to one side. At this time, the center of gravity adjustment mechanism 6 can be used to balance the entire lifting device.

[0040] It should be noted that during the adjustment of the blade position, when the two sets of lifting clamps 5 connected to the fixed frame 41 loosen the blade, the two sets of lifting clamps 5 connected to the adjusting frame 42 clamp the blade; when the two sets of lifting clamps 5 connected to the fixed frame 41 clamp the blade, the two sets of lifting clamps 5 connected to the adjusting frame 42 loosen the blade.

[0041] refer to Figure 2 and Figure 3 As shown in the partial structure, the upper surface of the hoisting frame 1 is provided with a sliding groove 10, and the inner wall of the adjusting frame 42 is rotatably connected with a roller 11, which rolls along the inside of the sliding groove 10.

[0042] Furthermore, each set of support bars 3 consists of two sets of short bars, with the two sets of short bars in each set of support bars 3 connected to the corresponding two sides of the lifting frame 1, and the sling 2 connected to the surface of the four sets of short bars away from the lifting frame 1.

[0043] Furthermore, a drive mechanism 8 is connected to the hoisting frame 1 for driving the adjusting frame 42 to move along the surface of the hoisting frame 1. The drive mechanism 8 includes a rotary motor 81. The surface of the hoisting frame 1 is provided with a toothed groove 82. An adjusting plate 83 is connected between the two sets of adjusting frames 42. The rotary motor 81 is connected to the surface of the adjusting plate 83. The drive end of the rotary motor 81 is fixedly connected to a gear 84 that meshes with the toothed groove 82.

[0044] In actual use, the starting motor 81 drives the gear 84 to rotate. Since the gear 84 and the tooth groove 82 mesh, the adjusting plate 83 and the adjusting frame 42 connected to the adjusting plate 83 will move. The adjusting frame 42 drives the lifting clamp 5 to move, thereby adjusting the position of the fan blades.

[0045] Furthermore, the flowable medium is sand particles.

[0046] In other embodiments, the flowable medium may also be other particulate media.

[0047] refer to Figure 3 and Figure 4 The structure shown includes two sets of adjustment boxes, namely a left box 61 and a right box 62. The conveying mechanism 9 includes a drive motor 91 and a spiral conveying roller 92. The drive motor 91 is connected to the surface of the left box 61 away from the lifting frame 1. The drive end of the drive motor 91 extends into the interior of the left box 61 and is connected to one end of the spiral conveying roller 92. The other end of the spiral conveying roller 92 extends through the conveying channel 7 into the right box 62 and is rotatably connected to the inner wall of the right box 62.

[0048] In actual use, if the hoisting device tilts and the left box 61 is higher than the right box 62, the drive motor 91 is started to drive the spiral conveyor roller 92 to rotate, so that the sand in the right box 62 is conveyed into the left box 61, thereby lowering the height of the left box 61 until the left box 61 and the right box 62 are at the same height. If the right box 62 is higher than the left box 61, the drive motor 91 is started to drive the spiral conveyor roller 92 to rotate in the opposite direction, so that the sand in the left box 61 is conveyed into the right box 62.

[0049] refer to Figure 2 As shown in the partial structure, fans 12 are installed on both sets of fixing brackets 41.

[0050] Specifically, the air outlet side of fan 12 is opposite to the opening side of the hanging clamp 5. It should be noted that in windy weather, due to the long blades of the fan, the blades will rotate in the horizontal direction. When the blades rotate, fan 12 can be turned on for adjustment. Specifically, viewed from top to bottom, when the blades rotate clockwise, fan 12 near the left box 61 can be turned on, and vice versa.

[0051] refer to Figure 5 and Figure 6 The structure shown includes a lifting clamp 5 comprising a drive member 51, an upper clamping plate shell 52, and a lower clamping plate shell 53. Inner clamping plates 54 are fixedly connected to the corresponding two sides of the upper clamping plate shell 52 and the lower clamping plate shell 53. The side of the upper clamping plate shell 52 away from the inner clamping plate 54 is connected to the corresponding connecting frame 4. An upper mounting groove 55 is formed on the surface of the upper clamping plate shell 52, and a lower mounting groove 56 is formed on the surface of the lower clamping plate shell 53. The end of the lower clamping plate shell 53 away from the inner clamping plate 54 is rotatably connected to the end of the upper clamping plate shell 52 away from the inner clamping plate 54. The non-drive end of the drive member 51 is rotatably connected to the corresponding connecting frame 4. The drive end of the drive member 51 extends through the upper mounting groove 55 into the lower mounting groove 56 and is rotatably connected to the inner wall of the lower mounting groove 56.

[0052] Among them, the driving component 51 is an electric push rod, hydraulic cylinder, pneumatic cylinder, etc.; the end of the upper clamping plate shell 52 and the lower clamping plate shell 53 away from the driving component 51 is the opening side of the lifting clamp 5; in actual use, when the lifting clamp 5 is needed to clamp the blade, the driving component 51 is started, and the driving component 51 drives the lower clamping plate shell 53 to rotate, so that the opening side of the lifting clamp 5 opens, and the blade can be clamped at this time. When the blade enters between the two sets of inner clamping plates 54 from the opening side of the lifting clamp 5, the driving component 51 is started again, so that the opening side of the lifting clamp 5 closes, thereby clamping the blade.

[0053] refer to Figure 5 and Figure 7As shown in the partial structure, the two sides of the two sets of inner clamping plates 54 are connected to airbags 13. The surface of the lifting frame 1 is connected to an air pump 14. The air outlet of the air pump 14 is connected to an air pipe 15 that is correspondingly set to the lifting frame 1. The end of each set of air pipes 15 away from the air pump 14 passes through the corresponding lifting clamp 5 and communicates with the airbag 13. A solenoid valve 16 is installed on the end of each set of air pipes 15 near the air pump, and a hydraulic valve 17 is installed on the end of each set of air pipes 15 away from the air pump.

[0054] Specifically, the end of each inflation tube 15 away from the inflation pump 14 passes through the corresponding inner clamping plate 54 connected to the upper clamping plate shell 52 and then communicates with the airbag 13.

[0055] It should be noted that, since the shape of the blade is different at different positions, the airbag 13 is set to adapt to the surface shape of the blade at different positions, thereby clamping the blade.

[0056] Example 2;

[0057] This embodiment provides a method for hoisting an anti-collision wind turbine, implemented using an anti-collision wind turbine hoisting device provided in Embodiment 1, and includes the following steps:

[0058] S1. Suspend the hoisting frame on the lifting equipment with slings, so that multiple sets of hoisting clamps correspond to the blades to be clamped.

[0059] S2. Start the air pump to inflate the airbag through the air inflator. After the airbag is inflated, start the hoisting clamp and work with the airbag to clamp the blades.

[0060] S3. If the blade position needs to be adjusted, first start the lifting clamp connected to the fixed frame to loosen the blade, then start the drive mechanism to drive the adjustment frame to move in the direction required to adjust the blade, and finally make the lifting clamp connected to the fixed frame clamp the blade to complete the blade position adjustment.

[0061] S4. After the blade position is adjusted, if the lifting frame tilts, start the drive motor and use the spiral conveyor roller to transport the flowable medium in the lower side adjustment box to the higher side adjustment box until the lifting frame is horizontally balanced.

[0062] S5. When the blades rotate horizontally in windy weather, turn on the fan on the corresponding side of the fixed bracket according to the direction of blade rotation, and adjust the blades to maintain stability by controlling the wind force.

[0063] S6. After the blade is hoisted to the designated position, the hoisting clamp removes the blade, completing the hoisting process.

[0064] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
