Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power piles, and particularly relates to an anti-scouring protection device for offshore wind power piles. Background Art

[0002] Wind power generation is the fastest growing green energy technology in the world. Due to the rich wind energy resources in the sea and the feasibility of current technologies, the ocean will become a rapidly developing wind power market. With the development and maturity of offshore wind farm technologies, wind power will surely become an important energy source for sustainable development in coastal areas.

[0003] After the foundation piles of wind power piles are fixed in the seabed, when seawater flows, it will scour and impact the foundation piles, and initial protection of the foundation piles cannot be carried out. Moreover, under the action of long-term seawater flow, the sediment around the offshore wind power pile foundation will also move with the seawater flow. The traditional anti-scouring method often throws stones at the seabed pile foundation to prevent the flow of sea sand. In this method, the stones often cannot accurately fall around the pile foundation, and the anti-scouring effect is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-scouring protection device for offshore wind power piles to solve the above problems, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-scouring protection device for offshore wind power piles provided by the utility model comprises a wind power pile body and two mutually adapted semi-circular sleeves. The open ends of the two semi-circular sleeves are detachably connected through an assembly structure, and the two semi-circular sleeves cooperate to form a sleeve sleeved on the outer side of the wind power pile body. A plurality of uniformly distributed water-permeable outward-expanding plates are rotatably connected to the lower part of the outer wall of each semi-circular sleeve. A floating bucket is fixedly connected to one side of the upper surface of each water-permeable outward-expanding plate away from the semi-circular sleeve, and a water inlet is arranged on the upper side of the floating bucket. Hollow grooves are formed inside the two semi-circular sleeves, and a sealing component for allowing water to enter the bottom is arranged in each hollow groove.

[0007] Adopt the above-mentioned offshore wind power pile anti-erosion protection device. By combining two semi-circular sleeves through an assembly structure and sleeving them outside the wind power pile body, at this time, several permeable outward-expanding plates unfold and turn outwards. Due to the buoyancy of seawater, the two semi-circular sleeves float on the water surface. At the same time, under the buoyancy of the floating barrels, several permeable outward-expanding plates also float on the water surface and are inclined. When the seawater impacts, it drives the permeable outward-expanding plates to turn upwards. Under their own gravity, the impact force of the seawater is unloaded, realizing the preliminary protection of the pile foundation. When it is necessary to protect the seabed, control the sealing component to cancel the seal. At this time, seawater enters the inside of the semi-circular sleeve from the bottom. As the hollow groove is gradually filled with seawater, it drives several permeable outward-expanding plates to sink into the sea. As they fall, seawater is poured into the floating barrels from the upper water inlets until several permeable outward-expanding plates are laid flat on the seabed, realizing the protection of the seabed pile foundation and preventing seawater from taking away sediment.

[0008] Preferably, a counterweight plate is integrally formed at the lower part of the semi-circular sleeve.

[0009] Preferably, the assembly structure includes T-shaped inserts fixedly connected to both ends of one of the semi-circular sleeves. T-shaped slots for inserting the T-shaped inserts are opened at the ends of the other semi-circular sleeve, and the bottom end of the T-shaped slot is sealed. Bolt connectors for fixing the other semi-circular sleeve are provided at the upper ends of both T-shaped inserts.

[0010] Preferably, the bolt connector includes a nut fixedly connected to the end of the upper surface of the semi-circular sleeve. A bolt is threadedly connected in the nut, and a fixing sleeve for inserting the bolt is fixedly connected to the upper end of the T-shaped insert.

[0011] Preferably, a groove is opened on the bottom surface of the permeable outward-expanding plate. A grid plate is fixedly connected in the groove, and the circular holes opened on the permeable outward-expanding plate are communicated with the grid plate.

[0012] Preferably, the sealing component includes through holes opened on the upper and lower side walls of the hollow groove. A sealing plug is inserted and connected in the lower through hole, and the sealing plug is located inside the hollow groove. A pull rope is fixedly connected to the upper end of the sealing plug, and the pull rope passes out from the upper through hole.

[0013] Preferably, the lower end of the sealing plug passes through the lower through hole and is sleeved with a reinforcing collar, and the diameter of the lower through hole is larger than that of the upper through hole.

[0014] The beneficial effects are as follows:

[0015] 1. By combining two semi-circular sleeves through an assembly structure and sleeving them outside the wind power pile body, several water-permeable outward-expanding plates unfold and turn outwards at this time. Due to the buoyancy of seawater, the two semi-circular sleeves float on the water surface at this time. At the same time, under the buoyancy of the floating barrels, several water-permeable outward-expanding plates also float on the water surface and are inclined. When impacted by seawater, it drives the water-permeable outward-expanding plates to turn upwards. Under their own gravity, the impact force of seawater is unloaded, realizing the preliminary protection of the pile foundation.

[0016] 2. When it is necessary to protect the seabed, control the sealing component to cancel the seal. At this time, seawater enters the inside of the semi-circular sleeve from the bottom. As the hollow groove is gradually filled with seawater, it drives several water-permeable outward-expanding plates to sink into the sea. As it falls, seawater is poured into the floating barrels from the upper water inlets until several water-permeable outward-expanding plates are laid flat on the seabed, realizing the protection of the pile foundation at the seabed, preventing seawater from carrying away sediment, improving the anti-scouring effect, and achieving the purpose of multi-purpose use.

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0024] See Figures 1-3 As shown, the present utility model provides an anti-erosion protection device for an offshore wind power pile, which includes a wind power pile body 1 and two mutually adapted semi-circular sleeves 2. The open ends of the two semi-circular sleeves 2 are detachably connected through an assembly structure, and the two semi-circular sleeves 2 cooperate to form a sleeve sleeved outside the wind power pile body 1. A plurality of evenly distributed permeable outwardly expanding plates 5 are rotatably connected to the lower part of the outer wall of each semi-circular sleeve 2. A floating bucket 6 is fixedly connected to one side of the upper surface of each permeable outwardly expanding plate 5 away from the semi-circular sleeve 2, and a water inlet is provided on the upper side of the floating bucket 6. Hollow grooves 7 are opened in the interiors of the two semi-circular sleeves 2, and a sealing member 4 for allowing water to enter the bottom is provided in each hollow groove 7. It is worth mentioning that, as Figure 1 or 3 shows, the fan-shaped appearance of the permeable outwardly expanding plate 5 is only a schematic diagram, which does not represent the actual shape, and its shape can be appropriately adjusted according to the actual situation, and can be rectangular, triangular, etc., so as to be able to turn smoothly and avoid the situation of collision and fighting between the two permeable outwardly expanding plates 5 when turning.

[0025] Specifically, a counterweight plate 10 is integrally formed at the lower part of the semi-circular sleeve 2. After the hollow groove 7 is filled with water, the weight of the semi-circular sleeve 2 can be increased, which can drive a plurality of floating buckets 6 to sink smoothly into the sea.

[0026] Refer to Figure 2 As shown, the assembly structure includes T-shaped inserts 8 fixedly connected to both ends of one of the semi-circular sleeves 2. A T-shaped slot 9 for inserting the T-shaped insert 8 is opened at the end of the other semi-circular sleeve 2, and the bottom end of the T-shaped slot 9 is designed to be sealed. Bolt connectors 3 for fixing the other semi-circular sleeve 2 are provided at the upper ends of the two T-shaped inserts 8. The bolt connector 3 includes a nut 3a fixedly connected to the end of the upper surface of the semi-circular sleeve 2. A bolt 3b is threadedly connected to the nut 3a. A fixing sleeve 3c for inserting the bolt 3b is fixedly connected to the upper end of the T-shaped insert 8. By placing the two semi-circular sleeves 2 one above the other, and then inserting the T-shaped insert 8 into the T-shaped slot 9, the assembly of the two semi-circular sleeves 2 is completed and sleeved outside the wind power pile body 1. Then, the bolt 3b is passed through the fixing sleeve 3c and rotated in the nut 3a to complete the assembly and prevent the T-shaped insert 8 from loosening.

[0027] Refer to Figure 3As shown, a groove 12 is formed in the bottom surface of the permeable outer expansion plate 5. A grid plate 11 is fixedly connected in the groove 12, and the circular holes formed in the permeable outer expansion plate 5 communicate with the grid plate 11. After the permeable outer expansion plate 5 is laid flat on the seabed, the grid plate 11 is closely fitted with the seabed sediment, further preventing sediment loss.

[0028] Referring to Figure 2 As shown, the sealing member 4 includes through holes 4a formed in the upper and lower side walls of the hollow groove 7. A sealing plug 4b is inserted and connected in the lower through hole 4a, and the sealing plug 4b is located inside the hollow groove 7. The upper end of the sealing plug 4b is fixedly connected with a pull rope 4d, and the pull rope 4d passes out through the upper through hole 4a. The lower end of the sealing plug 4b passes out through the lower through hole 4a and is sleeved with a reinforcing collar 4c. The diameter of the lower through hole 4a is larger than that of the upper through hole 4a. By pulling up the pull rope, the sealing plug 4b can be driven to cancel the blockage of the lower through hole 4a. At this time, seawater can be poured into the hollow groove 7 from the lower through hole 4a, enabling the semi-circular sleeve 2 to sink smoothly into the sea. The reinforcing collar 4c can improve the connection strength of the sealing plug 4b in the through hole 4a and prevent the sealing plug 4b from accidentally falling off in seawater.

[0029] With the above structure, the two semi-circular sleeves 2 are combined through the assembly structure and sleeved outside the wind power pile body 1. At this time, several permeable outer expansion plates 5 expand and flip outwards. Due to the buoyancy of seawater, the two semi-circular sleeves 2 float on the water surface. At the same time, under the buoyancy of the floating barrels 6, several permeable outer expansion plates 5 also float on the water surface and are inclined. When impacted by seawater, the permeable outer expansion plates 5 are driven to turn upwards, and under their own gravity, the impact force of seawater is unloaded, realizing preliminary protection of the pile foundation. When it is necessary to protect the seabed, the sealing member 4 is controlled to cancel the seal. At this time, seawater enters the inside of the semi-circular sleeve 2 from the bottom. As the hollow groove 7 is gradually filled with seawater, several permeable outer expansion plates 5 are driven to sink into the sea. During the falling process, seawater is poured into the floating barrels 6 from the upper water inlets until several permeable outer expansion plates 5 are laid flat on the seabed, realizing the protection of the seabed pile foundation and preventing seawater from carrying away sediment.

[0030] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
