Description

Technical Field

[0001] The utility model relates to a pile shoe, in particular to a pile shoe hexahedral bottom plate used for a deep-sea 1600-ton large-scale wind power installation platform, and belongs to the technical field of marine engineering. Background Art

[0002] Offshore wind power installation platforms can provide a stable working platform, so that workers can have better protection and support when installing wind turbines, thereby reducing possible accidents when workers operate at high altitudes. In addition, because the wind power installation platform has a stable structure and can cope with the influence of meteorological factors such as storms and rainstorms, it can ensure work safety and will not affect the progress of construction work, so it is increasingly used.

[0003] At present, the pile shoe of the offshore wind power installation platform is a tetrahedral bottom plate as follows Figure 1 , its contact surface with the seabed is mainly four faces, and the contact area between the four angular faces and the seabed is small, so the bearing capacity of the entire bottom plate is relatively small. If the four faces are directly connected, a welding concentration point will be formed in the middle, which is not allowed. The connection seam in the middle becomes larger, and the welding time is long and difficult. Moreover, each of the four faces cannot be balanced, and the stability of the platform is not utilized. With the development of offshore wind power new energy, the near-shore area is developing towards the deep sea and the offshore area, and the small wind turbine is developing towards the large wind turbine. The increase in seawater depth and the increase in loading and installation capacity require the wind power installation platform to become larger. Then the bearing capacity of the four pile shoes supporting the platform must be increased, so the original tetrahedral pile shoe bottom plate must be improved;

[0004] Patent CN207193934U discloses an octagonal pile shoe for a self-elevating platform, in which a central tube of the pile shoe and six bulkheads with an angle of 60 degrees to each other form a star-shaped structure and extend to the periphery of the pile shoe; the bottom of the pile shoe is a conical structure and is provided with a frustum, so that the pile shoe has a reasonable bottom area and structural form, can adapt to various offshore marine geological conditions and is convenient for platform pile insertion and extraction operations, but the pile shoe also needs to have a structural improvement on the top of the pile shoe to facilitate separation when moving, and a lot of force is still needed to rush out of the seabed when separating, so the strength is high and the efficiency is low, and the improvement of the overall pile shoe is large, and the production cost is increased.

[0005] Therefore, a hexahedral bottom plate of pile shoes for deep-sea 1600-ton large wind power installation platforms that can overcome the above defects is developed.

[0006] It has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a hexahedral bottom plate of pile shoes for a deep-sea 1600-ton large wind power installation platform, which not only increases the contact area but also facilitates movement and has strong adaptability.

[0008] In order to solve the above technical problems, the utility model provides a hexahedral bottom plate of a pile shoe for a deep-sea 1600-ton large-scale wind power installation platform, which is located at the bottom of the pile shoe and includes a bottom plate body and a high-pressure flushing hole. The bottom plate body protrudes downward to form a frustum structure, and a plurality of high-pressure flushing holes are evenly distributed on the bottom plate body. The high-pressure flushing holes are connected to the high-pressure pipes arranged inside the pile shoe;

[0009] The bottom plate body is composed of an assembly plate and a connecting plate. Six assembly plates with the same structure are tilted and arranged. The six assembly plates are sequentially spliced ​​to form a hexahedron. The middle of the hexahedron surrounded by the six assembly plates is connected and sealed by the connecting plate.

[0010] The technical solution further defined in the utility model is:

[0011] Furthermore, in the aforementioned hexahedral base plate of the pile shoe used for the deep-sea 1,600-ton large-scale wind power installation platform, the assembly plate is a trapezoidal structure.

[0012] In the aforementioned hexahedral base plate of the pile shoe used for the deep-sea 1,600-ton large-scale wind power installation platform, the connecting plate is a hexagonal structure.

[0013] Technical effect: the connecting plate of the utility model is adapted to the structure formed by six assembly plates, which facilitates better connection and sealing.

[0014] In the aforementioned pile shoe hexahedral bottom plate used for the deep-sea 1,600-ton large wind power installation platform, two groups of high-pressure flushing holes are arranged, each group of high-pressure flushing holes is evenly distributed on the bottom plate body, the center of each group of high-pressure flushing holes is on the same circumference, and the circles enclosed by the two groups of high-pressure flushing holes are concentric circles.

[0015] Technical effect: In the utility model, two groups of high-pressure flushing holes are arranged, and each group is evenly distributed in a concentric circle, which can expand the high-pressure water introduced into a concentric circle, loosen the seabed in a large range and facilitate the movement of the pile shoe.

[0016] In the aforementioned pile shoe hexahedral bottom plate used for the deep-sea 1,600-ton large wind power installation platform, two of the six assembly plates located on the opposite side of the connecting plate are trapezoidal structures, and the remaining four assembly plates have extension plates extending outward from one end away from the connecting plate to form a hexagonal structure.

[0017] Technical effect: The utility model arranges an extension plate on the assembly plate to reserve space for the wind power platform, which can be suitable for wind power platforms of multiple sizes and improves applicability.

[0018] In the aforementioned pile shoe hexahedral bottom plate used for the deep-sea 1,600-ton large-scale wind power installation platform, the acute angle formed between the assembly plate and the connection plate is 7°.

[0019] Technical effect: The acute angle formed between the assembly plate and the connecting plate is 7°, that is, the six assembly plates need to be assembled at an angle of 7° to the horizontal ground. This angle of inclination is designed based on the slope of the seabed when it is squeezed per unit area. It is more conducive to being close to the seabed.

[0020] The beneficial effects of the utility model are:

[0021] The utility model increases the bearing capacity of the pile shoe and increases the contact surface with the seabed by changing the shape of the bottom plate (i.e., changing the tetrahedron into a hexahedron). Each surface has the same 60° structure and can evenly distribute the force, thereby improving the stability of the offshore wind power installation platform. At the same time, an extended edge is extended on the edge of the assembly plate to reserve space to accommodate wind turbines of different sizes and improve applicability. A plurality of concentric groups of high-pressure flushing holes are provided on the assembly plate to flush water into the seabed soil to loosen the seabed and facilitate the lifting and movement of the pile shoe. One piece of floor can meet the requirements, thereby improving efficiency and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them; the technical features involved in the various implementation methods of the utility model described below can be combined with each other as long as they do not conflict with each other. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0026] The present embodiment provides a hexahedral bottom plate of a pile shoe for a deep-sea 1600-ton large-scale wind power installation platform, which is located at the bottom of the pile shoe and has a structure as shown in 2, including a bottom plate body and a high-pressure flushing hole 1. The bottom plate body protrudes downward to form a frustum structure, and a plurality of high-pressure flushing holes 1 are evenly distributed on the bottom plate body. The high-pressure flushing holes 1 are connected to the high-pressure pipes arranged inside the pile shoe;

[0027] The bottom plate body is composed of an assembly plate 2 and a connecting plate 3. The six assembly plates 2 of a trapezoidal structure are tilted, and the acute angle formed between the assembly plate 2 and the connecting plate 3 is 7°. The six assembly plates 2 are sequentially spliced ​​to form a hexahedron. The middle of the hexahedron surrounded by the six assembly plates 2 is connected and sealed by the connecting plate 3 of a hexagonal structure. Two assembly plates 2 located on the opposite side of the connecting plate 3 of the six assembly plates 2 are of a trapezoidal structure, and the other four assembly plates 2 are respectively extended outward from one end away from the connecting plate 3 to form an extension plate 4 to form a hexagonal structure.

[0028] Two groups of high-pressure flushing holes 1 are arranged, each group of high-pressure flushing holes 1 is evenly distributed on the bottom plate body, the center of each group of high-pressure flushing holes 1 is on the same circumference, and the circles corresponding to the two groups of high-pressure flushing holes 1 are concentric circles. The first group of high-pressure flushing holes is arranged with a circular high-pressure flushing hole on each assembly plate, and the second group of high-pressure flushing holes is located outside the first group of high-pressure flushing holes, and the second group of high-pressure flushing holes is arranged with two circular high-pressure flushing holes on each assembly plate.

[0029] During specific implementation, the bottom plate, top plate and side panels of the utility model constitute a pile shoe, a high-pressure pipe is installed inside the pile shoe, and a high-pressure flushing hole 1 is connected to the high-pressure pipe. This hole is the water outlet of the high-pressure pipe. When it needs to be moved, water is connected to flush water into the seabed soil to loosen the seabed and facilitate the lifting and movement of the pile shoe.

[0030] A large deep-sea wind power installation platform is heavy. To support it stably and safely, one of the important conditions is that the contact area between the bottom surface of the pile shoe of the supporting leg and the seabed must be increased. Through improvement, the utility model changes the tetrahedral bottom plate into a hexahedral bottom plate, which greatly increases the contact area and the bearing capacity. At the same time, each surface has the same 60° structure, which can evenly distribute the force and improve the stability of the offshore wind power installation platform. An extended edge is extended on the edge of the assembly plate to reserve space to accommodate wind power of different sizes and improve applicability. A plurality of concentric groups of high-pressure flushing holes are provided on the assembly plate, so that the seabed is loose and easy to move or detach. One piece of floor can meet the requirements, thereby improving efficiency and reducing costs.

[0031] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
