Description

Technical Field

[0001] This invention relates to the field of floating breakwaters, and in particular to a composite tendon tension leg floating breakwater. Background Technology

[0002] With the continuous development of marine resources, marine engineering facilities are facing increasingly severe challenges from the marine environment. As an important structure protecting ports, coastlines, and marine engineering facilities, the performance and stability of breakwaters are of paramount importance.

[0003] Traditional breakwater structures mainly include sloping, vertical, and hybrid types. However, these traditional structures have some shortcomings when facing complex and ever-changing marine environments. For example, sloping breakwaters require a large area and have high requirements for terrain; vertical breakwaters, although relatively compact in structure, are prone to capsizing or damage under strong wave action; hybrid breakwaters, while combining the advantages of sloping and vertical breakwaters to some extent, still suffer from structural complexity, high construction difficulty, and high cost.

[0004] In recent years, floating breakwaters have gradually attracted attention as a new type of marine protection structure. Floating breakwaters have advantages such as mobility, adaptability, and minimal environmental impact, enabling them to provide effective protection in various sea areas and marine environments. However, existing floating breakwaters suffer from insufficient stability, making them prone to drifting or capsizing under strong winds and waves. Summary of the Invention

[0005] The purpose of this invention is to provide a composite tendon tension leg floating breakwater. This addresses the technical problem of existing floating breakwaters' poor stability and tendency to capsize under extreme weather conditions such as strong winds and high waves.

[0006] A composite tendon tension leg floating breakwater includes, from top to bottom, an elevated platform, a deep-sea floating body, and a gravity anchor;

[0007] The elevated platform and the deep-sea floating body each include a number of platform plates and a number of floating body segments that are sequentially spliced ​​along a predetermined path along the breakwater. The gravity anchor includes a number of anchor blocks that are spaced apart on both sides of the elevated platform. The two sides of the platform plate are connected to the anchor blocks on both sides by a first tension tendon.

[0008] Optionally, a number of mesh grids for wave protection are provided on one side wall of the elevated platform.

[0009] Optionally, the elevated platform shown has several mesh gratings on both sides for wave protection, with the mesh openings of the mesh gratings on both sides being staggered.

[0010] Optionally, the two sides of the floating body segment are connected to the anchor blocks on both sides respectively through the second tension tendon.

[0011] Optionally, the elevated platform and the deep-sea floating body are connected by several support rods.

[0012] Optionally, the floating body segment includes a floating body skeleton, the floating body skeleton is covered with a filling foam, and the filling foam is provided with an outer shell.

[0013] Because of the adoption of the above technical solution, the present invention has the following advantages:

[0014] 1. This application uses tension tendons symmetrically arranged on both sides to tension the elevated platform, resulting in high stability of the floating breakwater and making it less prone to overturning. At the same time, the tensioning of the first tension tendon is completed on the water surface, reducing the difficulty of the tensioning construction.

[0015] 2. The floating breakwater of this application can be flexibly set up according to any path, and when the first tension tendon is not tensioned, the elevated platform, deep-sea floating body and mesh grid are all located on the water surface, which is convenient for towing and construction.

[0016] 3. In this application, the floating body segments are filled with buoyancy materials such as foam, eliminating the need for watertight ballast tanks, drainage, and maintenance personnel access, which can significantly reduce costs and extend service life.

[0017] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example:

[0026] like Figure 1 The present invention relates to a composite tendon tension leg floating breakwater, comprising, from top to bottom, an elevated platform 1, a deep-sea floating body 2, and a gravity anchor 3;

[0027] The elevated platform 1 and the deep-sea floating body 2 each include a number of platform plates 101 and a number of floating body segments 201 sequentially spliced ​​along a preset path of the breakwater. The gravity anchor 3 includes a number of anchor blocks 301 that are spaced apart on both sides of the elevated platform 1. The two sides of the platform plate 101 are connected to the anchor blocks 301 on both sides by a first tension tendon 4. The elevated platform 1 and the deep-sea floating body 2 are connected by a number of support rods 7.

[0028] like Figure 1 As shown, the two sides of the floating body segment 201 are connected to the anchor blocks 301 on both sides respectively through the second tension tendon 6.

[0029] As one embodiment of this application, a plurality of mesh gratings 5 ​​for wave protection are provided on one side wall of the elevated platform 1.

[0030] As another embodiment of this application, several mesh grid plates 5 for wave protection are provided on the side walls on both sides of the elevated platform 1, and the mesh holes of the mesh grid plates 5 on both sides are staggered.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the preset path of the breakwater can be any shape, such as a long strip or an S-shape, for example... Figure 3 As shown, to increase the stability of the floating breakwater, the floating body segment 201 and platform plate 101 can also be added laterally. In this embodiment, during installation, the first tension tendon 4 is tensioned at one end of the elevated platform 1, so that the mesh grid plate 5 is inserted into the water (at this time, the elevated platform 1 is on the water surface, and the deep-sea floating body 2 is below the water surface). Figure 1 , Figure 2 and Figure 3 Only a portion of the floating breakwater units are shown; in actual use, additional units can be added as needed, or they can be enclosed into structures such as rings.

[0032] This application uses first tension tendons 4 symmetrically arranged on both sides to tension the elevated platform 1, resulting in high stability of the floating breakwater and making it less prone to overturning. At the same time, the tensioning of the first tension tendons 4 is completed on the water surface, reducing the difficulty of the tensioning construction.

[0033] In this embodiment, the anchor block 301 can be an anchor block that sinks into the water or an anchor pile that is pre-installed on the bottom of the water. When installing the floating breakwater, the floating body composed of the elevated platform 1, the deep-sea floating body 2, the mesh grid plate 5 and the support rod 7 is first towed to the top of the gravity anchor 3. One end of the first tension tendon 4 and the second tension tendon 6 are connected to the anchor block 301. Then, the length of the first tension tendon 4 is adjusted by the winch 8 on the elevated platform 1. When the floating body sinks to the predetermined position, the other end of the second tension tendon 6 is tensioned and installed on the deep-sea floating body 2.

[0034] like Figure 4 As shown, the floating body segment 201 includes a floating body skeleton 2011, the floating body skeleton 2011 is covered with a filling foam 2012, and the filling foam 2012 is covered with an outer shell 2013.

[0035] In this embodiment, adjacent floating body sections 201 can be connected by welding or flanges. In this application, the floating body section 201 does not need to be equipped with a watertight ballast tank, nor does it need to pump out water, nor does it need to consider setting up maintenance passages for maintenance personnel, which can greatly reduce costs and increase its service life.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
