Description

Technical Field

[0001] This utility model relates to the field of wind power generation component transportation technology, specifically a large wind turbine nacelle sea transport support. Background Technology

[0002] A wind turbine nacelle is a device used to house the mechanical and electrical components of a wind turbine. When transporting the nacelle by sea, a marine support structure is required.

[0003] A search revealed that the patent, CN209739284U, entitled "A Utility Model of a Fixing Support for Large Cargo for Marine Transportation," includes a fixing base plate. Research and analysis revealed that while it offers advantages such as making the device easier to use and more applicable in daily life, it also has the following drawbacks to some extent.

[0004] For example, without multi-point support, the bracket can only fix the basic structure of the nacelle and cannot provide adaptable support according to the complex structure of the nacelle. This makes the nacelle prone to local stress concentration due to turbulence and tilting during sea transport, which not only affects the stability of the fixation but may also cause hidden damage to the precision components of the nacelle. In addition, the existing bracket is difficult to flexibly adjust the support points and force, and cannot meet the adaptation requirements of different models of nacelles. In order to solve the above technical problems, we have designed a large wind turbine nacelle sea transport bracket. Utility Model Content

[0005] The purpose of this utility model is to provide a large-scale wind turbine nacelle marine support system with the advantage of multi-point support function. It solves the problem that existing marine support systems cannot provide adaptable support according to the complex structural shape of the nacelle during use, which leads to local stress concentration of the nacelle due to turbulence and tilting during sea transport. This not only affects the stability of the fixation, but may also cause hidden damage to the precision components of the nacelle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large wind turbine nacelle marine support, comprising a base plate, with supports riveted to the front and rear sides of the top of the base plate, a sleeve movably fitted on the surface of the support, a frame riveted to the bottom of the sleeve, an adjusting cylinder slidably connected to the inner cavity of the frame, an adjusting screw threadedly connected to the opposite side of the adjusting cylinder, a limit block riveted to the opposite end of the adjusting screw, fastening bolts riveted to both sides of the adjusting cylinder, the opposite end of the fastening bolts penetrating the frame, and a fastening nut threadedly fitted on the surface of the fastening bolt.

[0007] Preferably, buffer rods are movably connected through the four corners of the bottom of the base plate, a connecting plate is riveted to the bottom end of the buffer rod, a spring is sleeved on the surface of the buffer rod, a damper is bolted to the top edge of the connecting plate, and the top of the damper is bolted to the base plate.

[0008] Preferably, each of the opposite sides of the sleeve is threaded with a positioning bolt, and the opposite ends of the positioning bolts are in contact with the bracket.

[0009] Preferably, a slider is riveted to the bottom of the frame, and grooves are provided on the front and rear sides of the top of the base plate, with the bottom of the slider extending into the inner cavity of the groove.

[0010] Preferably, the bottom of the base plate is bolted to a buffer airbag, and the left side of the buffer airbag is connected to an air nozzle.

[0011] Preferably, the top of the base plate is bolted to a rubber pad, and the number of limiting blocks is several.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the cooperation of a bracket, sleeve, frame, adjusting cylinder, adjusting screw, limiting block, positioning bolt, and fastening nut, has the advantage of multi-point support function. When the position of the limiting block needs to be adjusted left or right, the positioning bolt is loosened, and then the sleeve is moved left or right. The sleeve can then drive the frame and the limiting block to move left or right. When the limiting block needs to be moved up or down, the fastening nut is loosened, and the position of the limiting block can be adjusted by moving the adjusting cylinder up or down. Then, multiple limiting blocks are used to limit and fix different positions in the engine compartment, thereby providing adaptable support.

[0014] 2. This utility model has the advantage of buffering function through the cooperation of buffer rod, connecting plate, spring, damper, positioning bolt, slider, slide groove and buffer airbag. When the ship is affected by the waves during the operation, the bottom plate compresses the spring, damper and buffer airbag downward. The spring, damper and buffer airbag deform and then absorb the impact force, thereby avoiding the impact force from acting on the engine room at the top of the bottom plate.

[0021] Please see Figures 1-5 A large-scale wind turbine nacelle marine support includes a base plate 1. Supports 2 are riveted to the front and rear sides of the top of the base plate 1. A sleeve 3 is movably fitted onto the surface of the support 2, allowing it to move left and right on the surface of the support 2. This, in turn, moves a limiting block 7 left and right, adjusting its support position. A frame 4 is riveted to the bottom of the sleeve 3. An adjusting cylinder 5 is slidably connected to the inner cavity of the frame 4. An adjusting screw 6 is threaded through the opposite side of each adjusting cylinder 5. By rotating the adjusting screw 6, the limiting block 7 can be pushed closer to or further away from the nacelle. The contact force between the limiting block 7 and the engine compartment is precisely adjusted to ensure that the engine compartment is firmly fixed while avoiding damage caused by excessive compression. The limiting block 7 is riveted to the opposite end of the adjusting screw 6. By setting the limiting block 7, multi-point fixing is achieved by contacting the engine compartment surface, dispersing the force on the engine compartment and avoiding local stress concentration. Its position can be adjusted by multiple components to adapt to engine compartments of different shapes and sizes, improving the versatility of fixing. Fastening bolts 8 are riveted to both sides of the adjusting cylinder 5. The opposite end of the fastening bolt 8 penetrates the frame 4, and the fastening nut 9 is threaded on the surface of the fastening bolt 8.

[0022] Please see Figure 1 and Figure 4 A buffer rod 10 is movably connected through each of the four corners of the bottom of the base plate 1. A connecting plate 11 is riveted to the bottom end of the buffer rod 10. A spring 12 is fitted on the surface of the buffer rod 10. A damper 13 is bolted to the top edge of the connecting plate 11. By setting up the buffer rod 10, spring 12 and damper 13, when the base plate 1 is subjected to impact force, the spring 12 is compressed and deformed to absorb part of the energy, and the damper 13 slows down the vibration of the spring 12. The two work together to reduce the bumps of the base plate 1. The connecting plate 11 disperses and transmits the buffer force, enhances the stability of the overall buffer structure, and effectively protects the cabin from impact. The top of the damper 13 is bolted to the base plate 1.

[0023] Please see Figure 1On the opposite side of the sleeve 3, there are threaded connections to positioning bolts 14. By setting the positioning bolts 14, the sleeve 3 can be limited and fixed. The opposite ends of the positioning bolts 14 are in contact with the bracket 2.

[0024] Please see Figure 1 The bottom of the frame 4 is riveted with a slider 15. The front and rear sides of the top of the base plate 1 are provided with slide grooves 16. By setting the slider 15 and the slide groove 16, the slider 15 slides in the slide groove 16, which restricts the movement direction of the frame 4, prevents it from deviating, and ensures the accuracy and stability of the frame 4 and the components above it during adjustment. The bottom of the slider 15 extends into the inner cavity of the slide groove 16.

[0025] Please see Figure 2 The bottom of the base plate 1 is connected to a buffer airbag 17 by bolts. The left side of the buffer airbag 17 is connected to an air nozzle. By setting the buffer airbag 17, it becomes elastic after being inflated through the air nozzle, which can further absorb the impact force during the sea transport process. Together with the spring 12 and the damper 13, it forms multiple buffers, enhances the shock absorption effect of the sea transport support, and has a better buffering effect on low frequency vibration.

[0026] Please see Figure 1 A rubber pad 18 is bolted to the top of the base plate 1. By setting the rubber pad 18 and laying it on the top of the base plate 1, it directly contacts the cabin. By utilizing the elasticity and friction of the rubber, it can not only avoid the cabin from hard contact with the base plate 1 and cause scratches, but also increase the friction between the cabin and the base plate 1, prevent the cabin from sliding, and improve the fixing effect. The number of limit blocks 7 is several.

[0027] In use, the engine room is hoisted to the top of the rubber pad 18. The position of the limiting block 7 is adjusted according to the shape of the engine room. When the position of the limiting block 7 needs to be adjusted left and right, the positioning bolt 14 is loosened, and then the sleeve 3 is moved left and right. The sleeve 3 can drive the frame 4 and the limiting block 7 to move left and right. When the limiting block 7 needs to be moved up and down, the fastening nut 9 is loosened, and the position of the limiting block 7 can be adjusted by moving the adjusting cylinder 5 up and down. Then the adjusting screw 6 is rotated, and the adjusting screw 6 drives the limiting block 7 to move. The surface of the limiting block 7 contacts the engine room. Multiple limiting blocks 7 can limit and fix different positions of the engine room, thereby providing adaptive support. When the ship is affected by waves during operation, the bottom plate 1 compresses the spring 12, damper 13 and buffer airbag 17 downward. The spring 12, damper 13 and buffer airbag 17 deform and absorb the impact force, thereby preventing the impact force from acting on the engine room at the top of the bottom plate 1.

[0028] In summary, this large-scale wind turbine nacelle marine support system, through the cooperation of bracket 2, sleeve 3, frame 4, adjusting cylinder 5, adjusting screw 6, limit block 7, positioning bolt 14, fastening nut 9, buffer rod 10, connecting plate 11, spring 12, damper 13, positioning bolt 14, slider 15, slide groove 16, and buffer airbag 17, solves the problem that existing marine support systems cannot provide adaptable support according to the complex structural shape of the nacelle during use. This results in the nacelle being prone to local stress concentration due to turbulence and tilting during sea transport, which not only affects the stability of the fixation but may also cause hidden damage to the precision components of the nacelle.
