Among them, the most widely used passive collision avoidance systems are mainly facilities such as collision avoidance boxes that absorb impact energy through deformation. Such facilities are usually tightly attached to the protected objects and are point-type collision avoidance systems. They are mainly used for objects that lack buffer space and are usually the last line of defense for the protected objects. Moreover, the current point-type collision avoidance systems are mainly used for small point-type buildings (structures) such as bridge piers and drainage outlets, and are not suitable for large-scale surface-type buildings (structures) such as offshore wind farms.

[0028] In order to more clearly demonstrate the technical content of the present invention, it is further described below in conjunction with specific embodiments.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention mainly provides a floating flexible passive anti-collision system for protecting offshore engineering facilities, including a mooring buoy 1, a cable-lifting buoy 2, a horizontal anchor chain 3, a mooring anchor chain 31 and a sunken stone 4; wherein the mooring buoy 1 and the cable-lifting buoy 2 float on the sea surface respectively, and the mooring buoy 1 and the cable-lifting buoy 2 are connected in series through the horizontal anchor chain 3, and a plurality of sunken stones 4 are also connected to both ends of the mooring buoy 1, and the sunken stones 4 are arranged on the seabed and fixedly connected to the mooring buoy 1 through the mooring anchor chain 31; the mooring buoy 1, the cable-lifting buoy 2, the horizontal anchor chain 3 and the mooring anchor chain 31 can be fixed on the sea surface by the sunken stone 4, and a continuous physical interception facility is formed, thereby effectively preventing ships from entering by mistake, and ensuring the navigation safety of ships in the engineering waters and the safety of the engineering itself.

[0030] In this embodiment, the mooring buoy 1, the cable lifting buoy 2, the horizontal anchor chain 3 and the mooring anchor chain 31 are all provided in plurality, and their quantity can be configured according to the water depth conditions of the engineering waters, so as to meet the use in various engineering waters scenarios.

[0031] In this embodiment, the mooring buoys 1 are located at both ends of the structure, and horizontal anchor chains 3 are connected to the bottom of the mooring buoys 1. The mooring buoys 1 are fixedly connected to one of the cable-lifting buoys 2 through the horizontal anchor chains 3; wherein adjacent cable-lifting buoys 2 are also fixed through the horizontal anchor chains 3.

[0032] Specifically: Figure 2 As shown, the mooring buoy 1 includes a polymer buoy 11, a daytime mark 12 and a concrete counterweight 13, wherein the daytime mark 12 is fixedly arranged on the upper surface of the polymer buoy 11, the concrete counterweight 13 is fixedly arranged on the lower surface of the polymer buoy 11, and a mooring anchor chain 31 is arranged on the concrete counterweight 13, and the mooring anchor chain 31 is respectively connected to the cable-lifting float 2 and the sinking stone 4; in this embodiment, the daytime mark 12 mainly plays a warning and deterrent role, which can prevent ships from actively colliding and crossing the barrier; wherein the daytime mark 12 can be selected with a yellow fork-shaped top mark to give a certain warning effect; the purpose of the concrete counterweight 13 is mainly to use its own gravity to keep the mooring buoy in a relatively vertical and stable state, and cooperate with the daytime mark 12 on the mooring buoy to form a warning mark; wherein, the spacing between adjacent mooring buoys 1 is set to 400-600m.

[0033] like Figure 1 , Figure 3 As shown, in this embodiment, the cable lift floats 2 are equidistantly arranged between the mooring buoys 1 through horizontal anchor chains 3, and the spacing between adjacent cable lift floats 2 is set to 15-25m. The cable lift float 2 includes a plastic float 21 and a PE pipe 22, a round steel 23, a PE sealing sheet 24 and a lifting ring 25 with a nut 26 installed on the plastic float.

[0034] Specifically, the PE tube 22 is arranged at the inner center position of the plastic float 21, and the length of the PE tube 22 is set to be equal to that of the plastic float 21; a round steel 23 is also arranged in the PE tube 22, wherein the round steel 23 penetrates the plastic float 21, and round steel is reserved at both ends of the plastic float 21; correspondingly, threads are arranged at both ends of the round steel (for the sake of simplicity, not drawn in the figure), and the PE sealing sheet 24 is arranged at both ends of the plastic float, and is threadedly connected with the round steel 23 reserved outside the plastic float through a nut 26; in this embodiment, the PE sealing sheet 24 is used to seal the PE tube 22; at the same time, the arrangement of the round steel 23 in the PE tube can make the plastic float 21 vertically arranged on the sea surface, thereby increasing the stability of the structure (the plastic float relies on its own gravity, the buoyancy of the water, and the tension of the anchor chain to maintain balance).

[0035] Reference again Figure 3As shown, a lifting ring 25 is also provided at both ends of the plastic float 21, and the lifting ring 25 is connected to the round steel thread reserved outside the plastic float through a nut 26; wherein, one end of the lifting ring 25 with the nut is in close contact with the PE sealing sheet 24; in this embodiment, the lifting ring 25 can perform a pressurized fixing effect on the PE sealing sheet 24, and can also be fixed to the horizontal anchor chain 3; during the process, one end of the horizontal anchor chain 3 passes through the lifting ring 25 on one of the plastic floats and is fixed to the lifting ring 25, and the other end is fixed to the lifting ring 25 on the next plastic float, and so on, thereby realizing the serial fixation of the horizontal anchor chain 3 and multiple plastic floats 21.

[0036] In this embodiment, the number of horizontal anchor chains 3 and mooring anchor chains 31 is set to be multiple, and the mooring anchor chain 31 can select saddle chain + full chain link / half chain link / short chain link + swivel, shackle and other anchor chain bodies; the mooring anchor chain 31 and the horizontal anchor chain 3 comply with the "Buoy Anchor Chain" (JT / T 100-2005) standard; wherein, multiple horizontal anchor chains 3 and mooring anchor chains 31 connect the mooring buoy 1 and the cable lift buoy 2 in series, thereby forming a flexible anti-collision warning belt, and the flexibility mainly refers to the flexibility in space, and the interception line type can be set according to the needs of the project, and the shape can be changed accordingly with the state of waves and currents to alleviate a certain degree of wave and current energy; at the same time, the continuous physical structure can prevent ships from passing normally, thereby achieving a clear and clear interception warning effect.

[0037] It should be noted that: the present invention uses a buoy with an interception warning function to float on the water surface, and is not affected by the rise and fall of the water level during the process; and by setting up a continuous physical interception facility on the water surface, a visual interception warning effect is formed in a conspicuous state, thereby effectively preventing ships from entering by mistake, ensuring the navigation safety of ships in the project waters and the safety of the project itself.

[0038] At the same time, it can be seen from the structural characteristics of the present invention that the buoyancy and tensioning capacity of the floating structure system are mainly adapted to the body load and wave and current load; if a ship directly collides with the interception facility, the flexible chain structure will slide along the bottom of the ship, thereby causing damage to the hull surface or the driving structure. This possible damage can be directly anticipated by general ship operators, and thus will produce a better warning and deterrent effect, preventing ships from actively colliding and crossing the interception.

[0039] The above-mentioned related explanations and descriptions of the embodiments are for the convenience of those skilled in the art to understand and apply the present invention. It is obvious that those familiar with the art can easily make various modifications to these contents and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above-mentioned related explanations and descriptions of the embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
