[0026] In order to more clearly show the technical content of the present utility model, it will be further described below in conjunction with specific embodiments.
[0027] As Figure 1 、 Figure 2 、 Figure 3 shown, the present utility model mainly provides a floating flexible passive anti-collision system for the protection of 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 sinker 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. A plurality of sinkers 4 are also connected to both ends of the mooring buoy 1. The sinker 4 is arranged on the seabed and is fixedly connected to the mooring buoy 1 through the mooring anchor chain 31; through the sinker 4, 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 and form a continuous physical interception facility, so as to effectively prevent ships from straying in and ensure the navigation safety of ships in the engineering waters and the safety of the project itself.
[0028] 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 quantities can be configured according to the water depth conditions of the engineering waters, so as to meet the use in various engineering water scenarios.
[0029] In this embodiment, the mooring buoy 1 is located at both ends of the structure. Horizontal anchor chains 3 are connected to the bottom of the mooring buoy 1, and the mooring buoy 1 is fixedly connected to one of the cable-lifting buoys 2 through the horizontal anchor chain 3; wherein, adjacent cable-lifting buoys 2 are also fixed through the horizontal anchor chain 3.
[0030] Specifically: As Figure 2As shown in the figure, the mooring buoy 1 includes a polymer buoy 11, a daytime marker 12, and a concrete counterweight 13. Among them, the daytime marker 12 is fixedly arranged on the upper surface of the polymer buoy 11, and the concrete counterweight 13 is fixedly arranged on the lower surface of the polymer buoy 11. 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 buoy 2 and the sinker 4; in this embodiment, the daytime marker 12 mainly plays a warning and deterrent role, and can prevent ships from actively ramming and crossing the barrier; among them, the daytime marker 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 keep the mooring buoy in a relatively vertical and stable state by its own gravity, and cooperate with the daytime marker 12 on the mooring buoy to form a warning mark; among them, the distance between adjacent mooring buoys 1 is set to 400-600m.
[0031] As Figure 1 , Figure 3 shown, in this embodiment, the cable-lifting buoys 2 are arranged equidistantly between the mooring buoys 1 through the horizontal anchor chains 3, and the distance between adjacent cable-lifting buoys 2 is set to 15-25m. Among them, the cable-lifting buoy 2 includes a plastic floating body 21 and a PE pipe 22, a round steel 23, a PE sealing piece 24, and a lifting ring 25 with a nut 26 installed on the plastic floating body.
[0032] Specifically: the PE pipe 22 is arranged at the central position inside the plastic floating body 21, and the length of the PE pipe 22 is set to be equal to that of the plastic floating body 21; a round steel 23 is also arranged in the PE pipe 22, among which, the round steel 23 penetrates through the plastic floating body 21, and round steel is reserved at both ends of the plastic floating body 21; correspondingly, threads are arranged at both ends of the round steel (for simplicity, not clearly drawn in the figure), the PE sealing piece 24 is arranged at both ends of the plastic floating body, and is threadedly connected to the round steel 23 reserved outside the plastic floating body through the nut 26; in this embodiment, the PE sealing piece 24 is used to seal the PE pipe 22; at the same time, the arrangement of the round steel 23 in the PE pipe can make the plastic floating body 21 vertically arranged on the sea surface, increasing the stability of the structure (the plastic floating body relies on its own gravity, the buoyancy of water, and the tension of the anchor chain to maintain balance).
[0033] Refer again to Figure 3 shown, lifting rings 25 are also arranged at both ends of the plastic floating body 21, and the lifting rings 25 are threadedly connected to the round steel reserved outside the plastic floating body through nuts; among them, the end of the lifting ring 25 with the nut 26 is closely attached to the PE sealing piece 24; in this embodiment, the effect of the lifting ring 25 can pressurize and fix the PE sealing piece 24, and at the same time 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 floating bodies and is fixed to the lifting ring 25, and the other end is fixed to the lifting ring 25 on the next plastic floating body, and so on, so as to realize the series connection and fixation of the horizontal anchor chain 3 and multiple plastic floating bodies 21.
[0034] In this embodiment, the number of the horizontal anchor chains 3 and the mooring anchor chains 31 is set to be multiple. The mooring anchor chains 31 can be selected from saddle chains + full chain links / half chain links / short chain links + swivels, shackles and other anchor chain bodies; the mooring anchor chains 31 and the horizontal anchor chains 3 comply with the standard of "Buoy Anchor Chain" (JT / T 100-2005); wherein, the multiple horizontal anchor chains 3 and mooring anchor chains 31 connect the mooring buoy 1 and the cable-lifting buoy 2 in series, thereby forming a flexible anti-collision warning belt. The flexibility mainly refers to the flexible characteristics in space, and the intercepting line type can be set according to the needs of the project, and the shape can change correspondingly with the states of waves and currents to relieve a certain degree of wave and current energy; at the same time, the continuous physical structure can prevent ships from passing normally, so as to achieve a clear and distinct intercepting and warning effect.
[0035] It should be noted that: the floating body with the intercepting and warning function of the present utility model floats on the water surface and is not affected by the rise and fall of the water level during the process; and by setting a continuous physical intercepting facility on the water surface, a visual intercepting and warning effect is formed in a prominent state, so as to effectively prevent ships from straying in and ensure the navigation safety of ships in the project water area and the safety of the project itself.
[0036] At the same time, it can be known from the structural characteristics of the present utility model that the buoyancy and tying ability of its floating structure system are mainly adapted to the body load and wave and current loads; if a ship directly rams into this intercepting facility, the flexible chain system structure will slide along the bottom of the ship, resulting in damage to the hull surface or the driving structure. Such possible damage can be directly predicted by ordinary ship operators, so it will produce a good warning and deterrent effect to prevent ships from actively ramming and crossing the barrier.
[0037] The above relevant descriptions and the descriptions of the embodiments are for the convenience of those of ordinary skill in the art to understand and apply the present utility model. Those who are familiar with the technology in this field can obviously make various modifications to these contents easily, and apply the general principles described herein to other embodiments without creative labor. Therefore, the present utility model is not limited to the above relevant descriptions and the descriptions of the embodiments. The improvements and modifications made by those skilled in the art according to the disclosure of the present utility model without departing from the scope of the present utility model should be within the protection scope of the present utility model.
