Description

Technical Field

[0001] The invention belongs to the field of marine engineering, and in particular relates to a mooring connection device and a floating platform suitable for a shared anchor point. Background Art

[0002] The ocean is rich in resources, including wind energy, oil, natural gas, minerals and biological resources. As the development of shallow seas gradually becomes saturated, deep seas are gradually becoming the focus of development. Floating platforms are the main devices for developing deep sea resources, and anchor foundations play a vital role in floating marine engineering. As a component connecting floating structures to the seabed, anchor foundations can not only effectively resist the impact of natural forces such as wind, waves and currents, but also ensure the stability and safety of marine engineering structures.

[0003] The installation of mooring and anchor foundation is the most important part of the installation process of floating platforms. In addition to considering the corresponding technical requirements, we should also pay attention to economic benefits. During the installation of mooring anchor chain and pile foundation, the anchor chain can be connected to the pile foundation on the water, and then put into the water with the pile foundation, but it is necessary to build a platform on the seabed around the pile foundation to place the free end of the anchor chain. In addition, the anchor chain and pile foundation can also be put into the water separately, first install the pile foundation and then put the anchor chain underwater, and the anchor chain and pile foundation are connected underwater. It can be seen that the above installation operations are time-consuming and labor-intensive, which is not conducive to reducing costs and increasing efficiency.

[0004] Therefore, it is necessary to propose a mooring connection device and a floating platform suitable for a shared anchor point to reduce the manufacturing cost. Summary of the invention

[0005] In order to solve the technical problem mentioned in the background technology that the installation operations are time-consuming and labor-intensive, which is not conducive to reducing costs and increasing efficiency, a mooring connection device and a floating platform suitable for a shared anchor point are provided.

[0006] To achieve the above-mentioned purpose, the specific technical solution of a mooring connection device and a floating platform suitable for a shared anchor point of the present invention is as follows: A mooring connection device suitable for a shared anchor point comprises a supporting mechanism. A rotating mechanism is arranged in the circumference of the supporting mechanism. A chain is arranged on the rotating mechanism. The chain can be hung on the supporting mechanism.

[0007] Furthermore, the supporting mechanism includes a pile foundation and an outer cylinder arranged on the outer circumference of the pile foundation, the rotating mechanism is arranged on the outer cylinder, and the chain can be hung on the outer cylinder.

[0008] Furthermore, the diameter of the outer cylinder is 1.4-1.6 times the diameter of the pile foundation.

[0009] Furthermore, the supporting mechanism also includes an edge plate, which is arranged on the outer tube, and a notch is arranged on the edge plate, and the chain can be hung on the notch.

[0010] Furthermore, a gap is provided between the pile foundation and the outer cylinder. The edge plate further includes an extension plate, and the pile foundation and the outer cylinder are connected by the extension plate.

[0011] Furthermore, there are at least two edge plates and rotating mechanisms. Rotating mechanisms are provided on adjacent sides of each edge plate, and edge plates are provided on adjacent sides of each rotating mechanism.

[0012] Furthermore, the rotating mechanism includes a plurality of retaining plates. The plurality of retaining plates are arranged in two groups and are oppositely arranged. A rotating rod is provided between the two groups of retaining plates, and the chain is connected to the rotating rod.

[0013] Furthermore, each retaining plate is arranged in a triangular shape.

[0014] Furthermore, the pile foundation is arranged in a hollow structure.

[0015] A floating platform uses the above-mentioned mooring connection device applicable to shared anchor points.

[0016] The mooring connection device applicable to shared anchor points of the present invention has the following advantages: The mooring connection device applicable to shared anchor points overcomes the defect of building a platform on the seabed near the pile foundation to place the free end of the bottom chain in the prior art. It can directly place the free end of the chain on the support device. During the piling process, the chain will move downward together with the support device, thus avoiding problems such as the chain sinking into the ground and underwater connection of the pile foundation, and also reducing the installation difficulty.

[0017] The floating platform of the present invention has the following advantages: 1) Due to the design of the pile foundation and the outer cylinder, compared with the existing design of suspending the edge plate on the pile foundation, the number of edge plates on each pile foundation in the mooring connection device is now increased from one to two or more, thus realizing the function of sharing anchor points, greatly reducing the piling operation workload and lowering the installation cost; 2) The design of the outer cylinder is beautiful and material-saving. Since the diameters of the pile foundation and the outer cylinder are larger than that of the pile foundation, during the piling operation, the chain will not interfere with the piling operation, and the diameter of the outer cylinder can also be adjusted according to the number of mooring points, improving the overall flexibility.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0022] The ocean is rich in resources, including wind energy, oil, natural gas, minerals and biological resources. As the development of shallow seas gradually becomes saturated, deep seas are gradually becoming the focus of development. Floating platforms are the main devices for developing deep sea resources, and anchor foundations play a vital role in floating marine engineering. As a component connecting floating structures to the seabed, anchor foundations can not only effectively resist the impact of natural forces such as wind, waves and currents, but also ensure the stability and safety of marine engineering structures.

[0023] The installation of mooring and anchor foundation is the most important part of the installation process of floating platforms. In addition to considering the corresponding technical requirements, we should also pay attention to economic benefits. During the installation of mooring anchor chain and pile foundation, the anchor chain can be connected to the pile foundation on the water, and then put into the water with the pile foundation, but it is necessary to build a platform on the seabed around the pile foundation to place the free end of the anchor chain. In addition, the anchor chain and pile foundation can also be put into the water separately, first install the pile foundation and then put the anchor chain underwater, and the anchor chain and pile foundation are connected underwater. It can be seen that the above installation operations are time-consuming and labor-intensive, which is not conducive to reducing costs and increasing efficiency.

[0024] Please refer to the attached Figure 1 The present invention describes a mooring connection device and a floating platform suitable for a shared anchor point.

[0025] This embodiment provides a mooring connection device suitable for a shared anchor point. Figure 1 FIG. 1 is a schematic diagram of the structure of a mooring connection device suitable for a shared anchor point according to the present embodiment. Figure 1As shown in the figure, the mooring connection device includes a support mechanism 1. A rotating mechanism 2 is arranged circumferentially on the support mechanism 1. A chain 3 is arranged on the rotating mechanism 2, and the chain 3 can be hung on the support mechanism 1. This mooring connection device applicable to shared anchor points overcomes the defect in the prior art of building a platform on the seabed near the pile foundation 11 to place the free end of the bottom chain 3. It can directly place the free end of the chain 3 on the support device. During the piling process, the chain 3 will move downward together with the support device, thus avoiding problems such as the chain 3 sinking into the ground and underwater connection of the pile foundation 11, and also reducing the installation difficulty.

[0026] Further, as Figure 1 shown, the support mechanism 1 includes a pile foundation 11 and an outer cylinder 12 arranged on the outer circumference of the pile foundation 11. The rotating mechanism 2 is arranged on the outer cylinder 12, and the chain 3 can be hung on the outer cylinder 12. Due to the design of the pile foundation 11 and the outer cylinder 12, compared with the existing design of hanging the longitudinal plate 13 on the pile foundation 11, in the mooring connection device, the number of longitudinal plates 13 on each pile foundation 11 is now increased from one to two or more, thus realizing the function of sharing anchor points, greatly reducing the piling operation workload and lowering the installation cost.

[0027] Further, the diameter of the outer cylinder 12 is 1.4 - 1.6 times the diameter of the pile foundation 11.

[0028] Further, the support mechanism 1 further includes a longitudinal plate 13. The longitudinal plate 13 is arranged on the outer cylinder 12. There is a notch on the longitudinal plate 13, and the chain 3 can be hung on the notch.

[0029] In this embodiment, the longitudinal plate 13 is connected to the outer cylinder 12 through a snap design or spot welding. After the piling is completed and the chain 3 is installed, the longitudinal plate 13 can be easily removed.

[0030] Further, there is a gap between the pile foundation 11 and the outer cylinder 12. The longitudinal plate 13 further includes an extension plate 131, and the pile foundation 11 and the outer cylinder 12 are connected through the extension plate 131.

[0031] Further, as Figure 1 shown, there are at least two longitudinal plates 13 and rotating mechanisms 2. On each adjacent side of each longitudinal plate 13, there is a rotating mechanism 2, and on each adjacent side of each rotating mechanism 2, there is a longitudinal plate 13.

[0032] As a preferred embodiment of this embodiment, there are two longitudinal plates 13 and rotating mechanisms 2, and they are arranged at intervals.

[0033] In the mooring connection device of this embodiment, the number of longitudinal plates 13 on each pile foundation 11 is now increased from one to two or more, thus realizing the function of sharing anchor points, greatly reducing the amount of pile driving work and lowering the installation cost. In addition, the spaced arrangement of the longitudinal plate 13 and the rotating mechanism 2 reduces the difficulty of underwater connection between the anchor pile and the mooring, improves the work efficiency, and thus realizes the function of sharing anchor points, which can effectively save costs.

[0034] Further, the rotating mechanism 2 includes a plurality of retaining pieces 21. The plurality of retaining pieces 21 are arranged in two groups and are oppositely arranged. A rotating rod 22 is arranged between the two groups of retaining pieces 21, and the chain 3 is connected to the rotating rod 22.

[0035] Further, each retaining piece 21 is arranged in a triangular shape.

[0036] Optionally, the above-mentioned rotating mechanism 2 can also be replaced with a universal joint in the prior art, thus saving the design cost and manufacturing cost. Those skilled in the art can understand that the staff can select a suitable rotating mechanism 2 according to actual needs, and this embodiment does not make specific limitations.

[0037] Further, the pile foundation 11 is arranged in a hollow structure, which is convenient for the staff to drive piles.

[0038] This embodiment also provides a floating platform, which uses the above-mentioned mooring connection device applicable to sharing anchor points. The advantages of this floating platform are as follows: 1) Due to the design of the pile foundation 11 and the outer cylinder 12, compared with the existing design of hanging the longitudinal plate 13 on the pile foundation 11, the number of longitudinal plates 13 on each pile foundation 11 is now increased from one to two or more, thus realizing the function of sharing anchor points, greatly reducing the amount of pile driving work and lowering the installation cost; 2) The design of the outer cylinder 12 is beautiful and material-saving. And since the diameters of the pile foundation 11 and the outer cylinder 12 are larger than that of the pile foundation 11, therefore, during the pile driving operation, the chain 3 will not interfere with the pile driving work, and the diameter of the outer cylinder 12 can also be adjusted according to the number of mooring points, improving the overall flexibility.

[0039] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
