Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power engineering, and in particular to an offshore wind power single pile foundation scour protection reinforcement device. Background Art

[0002] In the field of offshore wind power engineering technology, large-diameter single pile foundations are widely used in offshore wind power projects because of their simple structure, easy production, and high construction efficiency. During operation, the single pile foundation needs to withstand environmental factors such as waves and currents. When the ocean current flows through the single pile foundation, a vortex structure will be formed around the single pile foundation. The vortex will carry away the seabed soil around the single pile foundation, and then form a scour pit around the single pile foundation. The existence of the scour pit will directly affect the bearing capacity of the single pile foundation. If the scour pit is too large, it will cause problems such as the collapse of the single pile foundation.

[0003] The Chinese patent with the patent publication number CN113266034A discloses a scour protection reinforcement structure and method for offshore wind power monopile foundation. The gravel layer is set in the seabed by filling the gravel layer. The backfill gravel layer can level the seabed and reduce the amount of gravel sinking into the seabed, thus reducing the amount of engineering work. The sand filter layer can prevent the sand in the lower seabed from reverse seepage. The gravel protective layer can increase the scour starting flow rate and reduce the risk of the protective material being washed away. The net bag gravel protection pier can further improve the bearing capacity of the monopile foundation. The four materials complement each other to form a new protective structure, which can achieve a good scour protection effect. The use of graded gravel can ensure that the amount of graded gravel sinking into the seabed is small, thereby minimizing the amount of backfill stone. The sand filter layer is then used to prevent the lower seabed soil from infiltrating upward through the lower backfill gravel layer, thereby causing the loss of seabed soil and leading to the overall failure of the scour protection device. However, the protective piers are not protected. Under the long-term scouring of the ocean current, the protective piers are easily damaged and broken, resulting in the failure of the protection measures.

[0004] In view of this, the present invention proposes an offshore wind power single pile foundation scour protection reinforcement device to solve the problems existing in the above-mentioned prior art. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

When the current passes, the rotating sleeve 5 is rotated by the driving plate 4, so that the roller brush 8 can be driven to rotate and move along the surface of the protective cover 3. During the rotation and movement of the roller brush 8, garbage and other substances attached to the surface of the protective cover 3 can be cleaned to prevent the protective cover 3 from being corroded by long-term residues. When the current flows, the rotating roller 10 can be driven by the blade 9 to rotate, so as to move The moving belt 12 moves the mounting frame 11 under the fixed block 19. The movement of the mounting frame 11 can clean the roller brush 8, ensuring the cleaning effect of the roller brush 8 on the protective cover 3 until the mounting frame 11 is stuck. As the roller brush 8 moves to the other side, the ocean current drives the blade 9 to rotate the roller 10 again. At this time, the rotation direction of the roller 10 is opposite to that before, so that the movement direction of the mounting frame 11 is opposite to that before, and the cycle is repeated, so that the cleaning plate 17 reciprocates on the surface of the roller brush 8, and the roller brush 8 is cleaned by multiple cleaning sticks 20.

[0030] As a further solution of the present invention, a mounting groove 21 is provided at the connection between the fixing block 19 and the mounting frame 11 , and a swing plate 24 is hingedly connected to the middle of the mounting groove 21 , and the bottom end of the swing plate 24 is hingedly connected to the top outer wall of the cleaning plate 17 .

[0031] As a further solution of the present invention, a rotating shaft 23 is provided on one side of the swing plate 24, and a cam 22 is fixedly connected to the outer wall of the rotating shaft 23, and a plurality of driving blades 18 are provided at one end of the rotating shaft 23.

[0032] As a further solution in the present invention, guide rods 16 are slidably connected on both sides of the mounting frame 11, and the outer wall on one side of the guide rods 16 is fixedly connected to the outer wall of the cleaning plate 17, and the outer wall on the other side of the guide rods 16 is fixedly connected to the limit plate, and a connecting spring 15 is fixedly connected between the limit plate and the outer wall of the mounting frame 11, and the connecting spring 15 is sleeved on the corresponding outer wall of the guide rod 16.

[0033] Working principle: By setting up the protective cover 3, the reinforced pier 2 can be protected to prevent the reinforced pier 2 from being damaged by the erosion of the current and causing the protective measures to fail, and when the current passes, the rotating sleeve 5 is rotated by the driving plate 4, thereby driving the roller brush 8 to rotate and move along the surface of the protective cover 3. During the rotation and movement of the roller brush 8, garbage and other substances attached to the surface of the protective cover 3 can be cleaned to prevent the protective cover 3 from being corroded due to long-term residue, and while the current flows, the rotating roller 10 can be rotated by driving the blade 9, thereby moving the mounting frame 11 under the fixed block 19 through the moving belt 12. The movement of the mounting frame 11 can clean the roller brush 8 to ensure the cleaning effect of the roller brush 8 on the protective cover 3, until the mounting frame 11 is stuck, and as the roller brush 8 moves to the other side. When the roller 10 rotates again, the ocean current drives the paddle 19, and the roller 10 rotates in the opposite direction to that before, so that the mounting frame 11 moves in the opposite direction to that before, and the cycle continues, so that the cleaning plate 17 moves back and forth on the surface of the roller brush 8, and the roller brush 8 is cleaned by multiple cleaning rods 20; and the ocean current drives the paddle 18 to rotate the shaft 23, so that the cam 22 on the shaft 23 rotates synchronously, and the cam 22 intermittently contacts the swing plate 24 during the rotation, so that the swing plate 24 deflects, and cooperates with the connecting spring 15 sleeved on the guide rod 16, so that the cleaning plate 17 in the mounting frame 11 moves back and forth, thereby greatly improving the cleaning effect of the roller brush 8, and the cleaning effect of the roller brush 8 is greatly improved by the flushing of the ocean current.

[0034] Example 2, reference Figure 1-Figure 7, an offshore wind power single pile foundation scour protection and reinforcement device, compared with embodiment 1, on the basis of embodiment 1, a tamping cover 25 is fixedly connected to the bottom outer wall of the protective cover 3, and a plurality of discharge ports 26 are arranged around the top outer wall of the tamping cover 25 at equal distances, a fixed plate 3 35 is fixedly connected to the outer wall on one side of the top of the discharge port 26, and a rotating shaft 2 33 is rotatably connected to the outer wall above the fixed plate 3 35, and a plurality of driving blades 3 34 are fixedly connected to the outer wall on one side of the rotating shaft 2 33 at equal distances, The outer wall on the other side of the rotating shaft 2 33 is fixedly connected with a cam 2 32. When the ocean current flows, it will carry a large amount of crushed stone, gravel and other materials. When the crushed stone, gravel and other materials move, because the protective cover 3 is a truncated cone, the crushed stone, gravel and other materials remain on the compacting cover 25 under the obstruction of the protective cover 3, and the crushed stone, gravel and other materials will enter the inside of the compacting cover 25 through the discharge port 26. At the same time, the ocean current can drive the rotating shaft 2 33 to rotate with the cam 2 32 by driving the blade 3 34.

[0035] As a further solution in the present invention, the inner wall of the discharge port 26 is fixedly connected with a fixed plate 27, and a slide bar 29 is slidably connected to the middle part of the fixed plate 27, the top outer wall of the slide bar 29 is fixedly connected with a fixed plate 21, and a connecting spring 28 is arranged between the fixed plate 21 and the fixed plate 27, the top outer wall of the fixed plate 21 is fixedly connected with an arc plate 30, and the arc plate 30 and the cam 2 32 are in the same vertical plane, and during the rotation of the cam 2 32, it will intermittently contact the arc plate 30 on the fixed plate 2 31, and through the elastic potential energy of the connecting spring 28, the fixed plate 2 31 can press the slide bar 29 to move back and forth up and down.

[0036] As a further solution in the present invention, the bottom of multiple slide bars 29 is fixedly connected to the same tamping plate 36, and inclined surfaces are provided on both sides of the top of the tamping plate 36. Gravel, sand and other materials entering the tamping cover 25 will fall on the tamping plate 36. Since inclined surfaces are provided on both sides of the top of the tamping plate 36, the gravel, sand and other materials will fall along the inclined surfaces to the bottom of the tamping plate 36. Gravel, sand and other materials will continue to gather under the tamping plate 36 to fill the flushed pit under the tamping cover 25. When the slide bar 29 reciprocates up and down, it will move the tamping plate 36 synchronously, thereby compacting the gravel, sand and other materials to avoid subsequent flushing, thereby greatly improving the protection effect of the single pile foundation.

[0037] Working principle: when the sea current flows, it will carry a large amount of crushed stones, gravel and other materials to move. When the crushed stones, gravel and other materials move, because the protective cover 3 is a truncated cone, the crushed stones, gravel and other materials remain on the compaction cover 25 under the obstruction of the protective cover 3, and the crushed stones, gravel and other materials will enter the inside of the compaction cover 25 through the discharge port 26. At the same time, the sea current can drive the blade 3 34 to make the rotating shaft 2 33 rotate with the cam 2 32. Because the arc plate 30 and the cam 2 32 are in the same vertical plane, during the rotation of the cam 2 32, it will intermittently contact the arc plate 30 on the fixed plate 2 31, and through the elastic connection spring 2 28 The potential energy can make the fixed plate 231 press the sliding bar 29 to move back and forth up and down, and the crushed stone, gravel and other materials entering the compaction cover 25 will fall on the compaction plate 36. Because the top of the compaction plate 36 is provided with inclined surfaces on both sides, the crushed stone, gravel and other materials will fall along the inclined surfaces to the bottom of the compaction plate 36. The crushed stone, gravel and other materials will continue to gather under the compaction plate 36 to fill the scour pit under the compaction cover 25. When the sliding bar 29 moves back and forth up and down, it will move the compaction plate 36 synchronously, thereby compacting the crushed stone, gravel and other materials to avoid subsequent scouring, thereby greatly improving the protection effect of the single pile foundation.

[0038] Example 3, reference Figure 1-Figure 8 , an offshore wind power single pile foundation scour protection reinforcement device, compared with embodiment 2, on the basis of embodiment 2, a through hole 37 is provided between two adjacent discharge ports 26, and a push plate 38 is provided between the through hole 37 and the discharge ports 26 on both sides thereof, the push plate 38 is slidably connected to the top outer wall of the tamping cover 25, and a connecting spring 39 is fixedly connected between the two push plates 38, a connecting plate 40 is hinged between the push plate 38 and the adjacent fixed plate 2 31, and the fixed plate 2 31 is pressed downward by the cam 2 32 during the process of moving In the process, the push plate 38 can be moved by the connecting plate 40, so that the push plates 38 on both sides of the through hole 37 compress the connecting spring three 39 to move closer to each other, and the crushed stone, gravel and other materials remaining on the compaction cover 25 can be pushed and fall into the compaction cover 25 through the through hole 37. When the fixed plate 2 31 moves upward, the push plate 38 is reset under the action of the rebound force of the connecting spring three 39 and the connecting plate 40, and the cycle is repeated, so that the speed at which the crushed stone, gravel and other materials enter the inside of the compaction cover 25 can be greatly accelerated, thereby greatly improving the speed of backfilling the flushing pit.

[0039] Working principle: When the fixed plate 2 31 is pressed downward by the cam 2 32, the push plate 38 can be moved through the connecting plate 40, so that the push plates 38 on both sides of the through hole 37 compress the connecting spring 3 39 to move closer to each other, and the crushed stone, gravel and other materials remaining on the compaction cover 25 can be pushed and fall into the compaction cover 25 through the through hole 37. When the fixed plate 2 31 moves upward, the push plate 38 is reset under the action of the rebound force of the connecting spring 3 39 and the connecting plate 40, and the cycle is repeated, thereby greatly accelerating the speed at which the crushed stone, gravel and other materials enter the inside of the compaction cover 25, and greatly improving the speed of backfilling the flushing pit.
