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 reinforcement and anti-scour device. Background Art

[0002] Offshore wind power refers to an energy development method that builds wind turbines on the ocean and uses ocean wind energy to generate electricity. Due to the action of waves and tides, the mud and sand around the offshore wind power pile foundation will be washed away to form scour pits, which will affect the stability of the pile foundation. The water flow mixed with mud and sand near the seabed surface constantly washes the pile foundation, corroding and damaging the surface of the pile foundation. In severe cases, it will cause the collapse of the offshore wind turbine unit, so a special anti-scour device will be installed on the outside of the pile foundation.

[0003] The prior art discloses an offshore wind power foundation anti-scour system with publication number CN118756757A. A sliding buffer frame is slidably provided on the wind power foundation for connecting a flexible mold bag to resist direct impact of ocean currents. When the flexible mold bag is filled with concrete, the air inside the flexible mold bag is discharged through a vacuum port, and water pressure is used to help the flexible mold bag fit tightly against the concrete. The present invention effectively resists direct impact of ocean currents on the flexible mold bag through the sliding buffer frame, and utilizes vacuum exhaust and water pressure assistance to form a tight bond between the flexible mold bag filled with concrete and the seabed, and to keep the flexible mold bag in close contact with the concrete, thereby avoiding the generation of bubbles and improving the anti-scour capability of the wind power foundation.

[0004] Although it can improve the anti-scour performance of wind power foundations, there are still some defects in actual use. Since the anti-scour device of the offshore wind power is an integrated structure, when the anti-scour device is used on the seabed for a long time, it is impacted by gravel in the seabed water flow.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-9An offshore wind power reinforcement and anti-scour device shown in the figure includes a foundation pile 1 buried in the seabed, an annular ballast box 2 is provided on the outer wall of the foundation pile 1, and a pair of protective covers 3 are provided on the outer wall of the annular ballast box 2. It should be noted here that the inner walls of the annular ballast box 2 and the protective cover 3 are in contact with the outer wall of the foundation pile 1 except for the position above the support seat 8, so as to avoid the annular ballast box 2 and the protective cover 3 from shaking freely on the foundation pile 1 when the upper pull rope 10 and the lower pull rope 11 are pulled, thereby affecting the stability of subsequent installation. It can ensure that the annular ballast box 2 and the protective cover 3 slide downward vertically and accurately, and the protective covers 3 are connected by bolts. After the protective covers 3 are connected, they are in a cone shape. The outer wall of the foundation pile 1 and located above the protective cover 3 are slidably connected with a top ring 4. The wall is slidably connected with a bottom ring 5 under the top ring 4, a pair of connecting rods 6 are fixedly connected between the top ring 4 and the bottom ring 5, a pair of fixing rings 7 are provided on the outer wall of the foundation pile 1, and the fixing rings 7 are fixedly connected by bolts. A fixing mechanism for fixing the annular counterweight box 2 is provided on the fixing ring 7, and a support seat 8 is fixedly connected to the top of the fixing ring 7, and a roller 9 is rotatably connected to the inner side of the support seat 8. Upper pull ropes 10 are provided on both sides of the foundation pile 1, and the bottom of the upper pull rope 10 passes through the bottom of the roller 9 and is fixedly connected to the bottom end of the bottom ring 5, and a lower pull rope 11 is fixedly connected to the top of the top ring 4. An installation mechanism for retracting and releasing the upper pull rope 10 and the lower pull rope 11 is provided on the outer wall of the foundation pile 1 and located above the sea surface, and a limiting mechanism for fixing the protective cover 3 is provided on the inner side of the annular counterweight box 2;

[0031] The fixing mechanism includes a right-angle block 22 with an inclined surface, and the right-angle block 22 is provided with a pair of grooves 23 on both sides of the fixing ring 7. The right-angle blocks 22 are slidably connected to the inner side of the groove 23. A pair of fixing blocks 24 are fixedly connected to the inner side of the annular counterweight box 2 and located on the upper and lower sides of the right-angle block 22, and the fixing blocks 24 are arranged on both sides of the right-angle block 22 to prevent the support seat 8 and the roller 9 from hindering the fixing block 24 from sliding downward, and at the same time do not affect the right-angle block 22 from being stuck between the fixing blocks 24 to perform a limiting function. A lower spring 25 is fixedly connected between the inner side of the groove 23 and the right-angle block 22, and the lower spring 25 facilitates the pushing of the right-angle block 22 to be stuck between the fixing blocks 24 for fixing;

[0032] When installing the reinforcement anti-scour device on the foundation pile 1, first, when the foundation pile 1 is installed, the fixing ring 7 is installed at the specified position of the outer wall of the foundation pile 1 (the position of the fixing ring 7 can be calculated according to the depth of the foundation pile 1 on the seabed), and the upper pull rope 10 is passed through the roller 9 (both ends of the upper pull rope 10 are on the sea surface), and then when the foundation piles 1 are installed one by one and leak out of the sea surface (the foundation pile 1 is composed of a plurality of rods of the same length), the annular counterweight box 2 can be put on the foundation pile 1 (at this time, the annular counterweight box 2 and the protective cover 3 are connected by a limiting mechanism), and the foundation pile 1 with the circular frame 28 is installed, and then one end of the upper pull rope 10 is fixedly wound on the upper winding roller 26, and the other end is installed at the bottom of the bottom ring 5, and at the same time, the bottom of the lower pull rope 11 is fixed to the top of the top ring 4;

[0033] Then, after the installation of the wind turbine structure is completed, the counterweight concrete can be poured into the annular counterweight box 2 through the grouting port 20, and then the plug 21 is screwed on to seal it. Then, the driving end of the electric gun is inserted into the socket 39 corresponding to the upper winding roller 26, and the pull rod 37 is pulled to release the rotation restriction of the positioning mechanism on the gear ring 31. Then, the electric gun is controlled to start and drive the plug block 33 to rotate, and at the same time drive the gear 32 to rotate, and drive the meshing gear ring 31 and the upper winding roller 26 to rotate, and then the upper pull rope 10 is wound up, and the bottom ring 5 is pulled downward by the upper pull rope 10 to slide, and move downward through the connecting rod 6 and the top ring 4. At this time, the top ring 4 is stuck on the protective cover 3, which will drive the annular counterweight box 2 and the protective cover 3 on the foundation pile 1 At the same time, the upper and lower parts slide downward, thereby pulling the annular counterweight box 2 to the seabed, so that the tooth 19 is inserted into the seabed, and driving the fixed block 24 to slide past the right-angle block 22. At this time, the fixed block 24 at the bottom will squeeze the inclined surface of the right-angle block 22, thereby pushing the two right-angle blocks 22 to slide toward the closer side and compressing the lower spring 25. Then, when the tooth 19 is fully inserted, the bottom fixed block 24 moves out from the right-angle block 22, thereby releasing the squeezing of the right-angle block 22, and then the right-angle block 22 is pushed back to its original position under the elastic force of the lower spring 25, so that the right-angle block 22 is stuck between the fixed blocks 24, thereby fixing the position of the annular counterweight box 2, thereby playing an anti-scouring reinforcement role for the bottom of the foundation pile 1, and finally loosening the pull rod 37 to take out the electric gun.

[0034] In order to be able to quickly take out and install the protective cover 3, the limiting mechanism includes an L-shaped rod 12, U-shaped grooves 13 are provided at both ends of the inner side of the annular counterweight box 2, a pair of L-shaped rods 12 are provided, and the L-shaped rods 12 are slidably connected to the inner side of the U-shaped groove 13, the bottom of the protective cover 3 is fixedly connected to a bottom plate 14, and a slot 15 is provided on the side wall of the bottom plate 14 at a position corresponding to the L-shaped rod 12, and a round rod 16 is fixedly connected to the side wall of the L-shaped rod 12, and a push block 17 for pushing the round rod 16 is fixedly connected on both sides of the outer wall of the bottom ring 5, and the push block 17 The upper and lower sides are inclined, the side walls of the round rod 16 are set as smooth arc surfaces, and the ends of the round rod 16 are set as smooth arc surfaces, so that the round rod 16 can be squeezed more smoothly by the inclined surface of the push block 17 to slide, and a pair of upper springs 18 are fixedly connected between the inner side of the U-shaped groove 13 and the side walls of the L-shaped rod 12. Through the setting of the upper springs 18, it is convenient to push the L-shaped rod 12 to reset, and the top of the L-shaped rod 12 is inclined. By setting the top of the L-shaped rod 12 inclined, the push block 17 can push the L-shaped rod 12 into the U-shaped groove 13 more smoothly;

[0035] The installation mechanism includes an upper winding roller 26 and a lower winding roller 27. A circular frame 28 is fixedly connected to both sides of the outer wall of the foundation pile 1 and is located above the sea surface. The upper winding roller 26 and the lower winding roller 27 are each provided with a pair. The upper winding roller 26 is rotatably connected to the side of the inner wall of the circular frame 28 that is close to it, and the lower winding roller 27 is rotatably connected to the side of the inner wall of the circular frame 28 that is away from it. The top of the upper pull rope 10 is wound and fixedly connected to the outer wall of the upper winding roller 26, and the top of the lower pull rope 11 is wound and fixedly connected to the outer wall of the lower winding roller 27. It should be noted here that the winding directions of the upper pull ropes 10 wound on the upper winding roller 26 are the same. The winding directions of the lower pull ropes 11 wound on the lower winding rollers 27 are the same, a circular hole is opened inside the foundation pile 1 and at a position corresponding to the circular frame 28, a cylinder 29 is fixedly connected between the upper winding rollers 26 and located at the circular hole, a circular rod 30 is fixedly connected between the lower winding rollers 27 and located inside the cylinder 29, and a positioning mechanism for limiting the rotation of the upper winding rollers 26 and the lower winding rollers 27 is provided on the circular frame 28, a gear ring 31 is fixedly connected to the outer wall of one of the upper winding rollers 26 and one of the lower winding rollers 27, and a gear 32 is rotatably connected to the inner side of the circular frame 28 and at a position corresponding to the gear ring 31;

[0036] The gears 32 are meshed with the corresponding gear rings 31 respectively. The side walls of the gears 32 are fixedly connected with plug blocks 33 and are arranged through the outer wall of the round frame 28. The plug blocks 33 are provided with a plug hole 39 for inserting the driving end of the electric gun. One of the side walls of the round frame 28 is provided with an indication arrow 34 for indicating the disassembly direction. The setting of the indication arrow 34 facilitates the on-site installers to clearly understand which plug block 33 to rotate to take up or send down the protective cover 3, thereby improving the convenience of the device.

[0037] When the protective cover 3 needs to be replaced after long-term use, first insert the driving end of the electric gun into the socket 39 corresponding to the lower winding roller 27, then pull the pull rod 37 to release the rotation restriction of the positioning mechanism on the gear ring 31, and then control the electric gun to start and drive the plug block 33 to rotate, and at the same time drive the gear 32 to rotate, and drive the meshing gear ring 31 and the lower winding roller 27 to rotate, so as to reel in the lower pull rope 11, and drive the top ring 4 to move upward through the lower pull rope 11, and at the same time drive the bottom ring 5 to move upward through the connecting rod 6, and pull the upper pull rope 10 downward under the guidance of the roller 9, so that the upper pull rope 10 wound on the upper winding roller 26 is gradually pulled out, and then the push block 17 is driven to move to the side of the round rod 16 through the movement of the bottom ring 5, and then the round rod 16 is squeezed to move by the inclined surface on the top of the push block 17, and the L-shaped rod 12 is driven to move and slide out of the card slot 1 5, and at the same time compress the upper spring 18, thereby releasing the restriction on the bottom plate 14, and then the round rod 16 slides out from the inclined surface of the push block 17 and squeezes onto the side wall of the push block 17, thereby maintaining the squeezing of the round rod 16, and then the bottom ring 5 moves to the bottom of the bottom plate 14, thereby pushing the bottom plate 14 to move upward, and at the same time driving the protective cover 3 to slide on the pile 1, thereby automatically taking out the protective cover 3, and then removing the bolts between the protective cover 3, taking out the protective cover 3, and then installing a new protective cover 3 on the outer wall of the pile 1, and located between the top ring 4 and the bottom ring 5, and then the driving end of the electric gun can be inserted into another socket 39, and the electric gun can be controlled to start and drive the upper winding roller 26 to wind up through the gear 32 and the gear ring 31, so as to repeat the above operation in reverse to install the protective cover 3 back, thereby realizing the rapid replacement of the protective cover 3, and greatly improving the convenience performance of the device.

[0038] In order to facilitate the pouring of counterweight concrete in the annular counterweight box 2, a number of splines 19 for inserting into the seabed are equidistantly fixedly connected to the bottom of the annular counterweight box 2. Through the setting of the splines 19, it is convenient to insert the splines 19 into the seabed near the foundation pile 1 when the annular counterweight box 2 is pushed downward by the winding upper pull rope 10, thereby further improving the fixing effect of the annular counterweight box 2. Grouting ports 20 are provided on the tops of the annular counterweight box 2 and the protective cover 3. The grouting ports 20 on the annular counterweight box 2 are threadedly connected with plugs 21 on the inner sides. Through the setting of the grouting ports 20, it is convenient to pour concrete and other counterweight materials in the annular counterweight box 2, and then screw on the plugs 21 to seal the grouting ports 20 on the annular counterweight box 2.

[0039] In order to limit the rotational position of the upper winding roller 26 and the lower winding roller 27 to prevent the upper winding roller 26 and the lower winding roller 27 from rotating at will when not in use, the positioning mechanism includes a tooth block 35, a positioning plate 36 is slidably connected to the top end of one of the circular frames 28, a pair of tooth blocks 35 are provided, and the tooth blocks 35 are fixedly connected to the bottom end of the positioning plate 36, a pull rod 37 is fixedly connected to the top of the positioning plate 36 and runs through the top end of the circular frame 28, and the pull rod 37 is convenient for stretching the positioning plate 36 and the tooth block 35 to move upward, so as to quickly release the rotation restriction of the gear ring 31, and a pair of positioning springs 38 are fixedly connected between the inner side of the circular frame 28 and the top end of the positioning plate 36, so that the positioning springs 38 can facilitate the tooth block 35 to be stuck on the gear ring 31, so as to limit the rotation of the gear ring 31;

[0040] The elastic force of the positioning spring 38 pushes the positioning plate 36 and the tooth block 35 to move downward and get stuck on the gear ring 31. Since the positioning plate 36 and the pull rod 37 can only slide up and down on the outer wall of the circular frame 28, the rotation position of the tooth block 35 is restricted. Therefore, the rotation position of the gear ring 31, the upper winding roller 26 and the lower winding roller 27 can be restricted. Subsequently, when it is necessary to release the rotation restriction of the gear ring 31 during use, the pull rod 37 is pulled upward to drive the positioning plate 36 to slide upward, and at the same time drive the tooth block 35 to slide out of the engagement with the gear ring 31, and compress the positioning spring 38 to release the rotation restriction of the gear ring 31. Finally, after use, release the pull rod 37 to push the positioning plate 36 to return to its original position under the elastic force of the positioning spring 38, and drive the tooth block 35 to get stuck on the corresponding gear ring 31, thereby realizing the rotation restriction of the upper winding roller 26 and the lower winding roller 27.

[0041] The basic principles, main features and advantages of the present invention are shown and described above.

[0042] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
