Description

Technical Field

[0001] This invention relates to the field of web page technology, and in particular to a marine key target protection network system. Background Technology

[0002] Key marine targets include offshore wind power projects, offshore platforms, and offshore exploration platforms. The foundation of an offshore platform is responsible for supporting the entire platform, and its safety is paramount. During operation, the foundation must withstand environmental factors such as waves and currents. When ocean currents flow past the foundation, they create vortex structures around it. These vortices erode the foundation, directly affecting the bearing capacity of the monopile foundation. If the erosion force is too great, it can cause problems such as foundation collapse. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a marine key target protection net system that effectively ensures the safe use of marine bases.

[0004] To achieve the above objectives, the technical solution provided by this invention is as follows: a marine key target protection net system, comprising a marine base, a sand-bearing bottom net connected to the outside of the marine base, a positioning rope and a base rope connected to the sand-bearing bottom net, the positioning rope being connected to a positioning anchor, the base rope being connected to the marine base, and multiple sets of impact buffer units arranged from top to bottom on the outside of the sand-bearing bottom net; buoy seats are provided on the water surface outside the marine base, buoy ropes are connected between adjacent buoy seats, buoy balls are connected to the buoy ropes, and the buoy ropes are connected to the positioning anchors by connecting ropes.

[0005] The impact buffer unit includes a filling net bag, a net-supporting rope, and a net-supporting float. The filling net bag has a "V" shaped cross-section, with the length of its inner wall being greater than the length of its outer wall. The inner wall of the filling net bag is connected to the sand-supporting bottom net, and a side rope is connected to the top of the outer wall. The net-supporting float is fitted onto the side rope, and a buffer rope is connected to the side rope. The buffer rope is connected to the float rope, and the filling net bag is filled with a buffer medium.

[0006] The width of the upper layer of filling netting is smaller than the width of the lower layer of filling netting, and the width of the bottommost layer of filling netting is smaller than the width of the bottom pocket.

[0007] The bottom of the sand-bearing net is bent outward and upward to form a bottom pocket. The top of the bottom pocket is connected to the float rope. The bottom pocket is filled with a cushioning medium, and the positioning rope is connected to the lower part of the outer side of the bottom pocket.

[0008] One end of the connecting rope is connected to the float rope, and the other end of the connecting rope is connected downwards to the middle or lower part of the positioning rope.

[0009] The buoy seats are multiple and distributed on the water surface around the marine base.

[0010] The buffer medium is pebbles, sand, or a wave-damping module.

[0011] In this invention, after adopting the above-mentioned solution, the top of the sand-supporting net is connected to the marine base via a base rope, and the bottom of the sand-supporting net is positioned by a positioning anchor, so that the sand-supporting net is suspended between the marine base and the positioning anchor. The upper part of the sand-supporting net is above the horizontal plane, and the lower part of the sand-supporting net is below the horizontal plane. Then, the buffer medium is filled into the impact buffer unit. When it is impacted by the water surface, the waves will directly rush towards the impact buffer unit (buffer medium). The impact force is buffered and eliminated by the buffer medium, thereby preventing the waves from directly impacting the marine base and effectively ensuring the safety of the marine base.

[0015] The present invention will be further described below with reference to all accompanying drawings. A preferred embodiment of the present invention is shown in the accompanying drawings. Figure 1 To be continued Figure 3 This embodiment of a marine key target protection net system includes a marine base 1, a sand-supporting bottom net 2 connected to the outside of the marine base 1, a positioning rope 3 and a base rope 4 connected to the sand-supporting bottom net 2, the positioning rope 3 connected to the positioning anchor 5, and the base rope 4 connected to the marine base 1. Multiple sets of impact buffer units are arranged from top to bottom on the outside of the sand-supporting bottom net 2. Buoy seats 6 are provided on the water surface outside the marine base 1, with multiple buoy seats 6 distributed around the marine base 1. Float ropes 7 connect adjacent buoy seats 6, and float balls 8 are connected to the float ropes 7. The float ropes 7 and the positioning anchor 5 are connected by connecting ropes 9. One end of the connecting rope 9 is connected to the float rope 7, and the other end of the connecting rope 9 is connected downwards to the middle or lower part of the positioning rope 3.

[0016] The impact buffer unit includes a filling net bag 10, a net-supporting rope 11, and a net-supporting float 12. The filling net bag 10 has a "V" shaped cross-section, with its inner wall being longer than its outer wall. The inner wall of the filling net bag 10 is connected to the sand-retaining bottom net 2, and a side rope is connected to the top of the outer wall. The net-supporting float 12 is fitted onto the side rope, and a buffer rope 13 is connected to the side rope. The buffer rope 13 is connected to the float rope 7. The filling net bag 10 is filled with a buffer medium 14, which is pebbles, sand, or wave-damping modules. The width of the filling net bag 10 in the upper layer is smaller than that in the lower layer, and the width of the bottommost filling net bag 10 is smaller than that of the bottom bag. The bottom of the sand-retaining bottom net 2 is bent outward and upward to form a bottom bag. The top of the bottom bag is connected to the float rope 7, and the bottom bag is filled with the buffer medium 14. A positioning rope 3 is connected to the lower outer side of the bottom bag.

[0017] A buoy is installed in each of the four directions around the marine base for positioning. The four buoys are connected by float ropes to form a ring around the marine base. The floats on the ring provide buoyancy, keeping the ring floating on the sea surface.

[0018] The sand-supporting bottom net consists of four pieces, each located in the direction below the marine base. Adjacent sand-supporting bottom nets are connected by net ropes. The top of the sand-supporting bottom net is connected to the base rope, the base rope is connected to the marine base, and the bottom of the sand-supporting bottom net is connected to the positioning rope, which is connected to the positioning anchor.

[0019] The positioning anchor is thrown to the outside and below the marine base. After the positioning anchor is fixed, the sand-bearing bottom net forms an inclined surface. The four sand-bearing bottom nets combined form a trapezoidal enclosure net with a smaller top and a larger bottom. The bottom of the sand-bearing bottom net is folded outward and upward and connected to the float rope to form a bottom pocket.

[0020] The filling nets are connected to the sand-collecting bottom net from top to bottom. Float balls are connected to the outside of the filling nets. The float balls of the middle and upper filling nets do not contact the water surface, while the float balls of the lower filling nets do contact the water surface.

[0021] The width of the next layer of filling net is greater than that of the previous layer. In this way, even if the upper layer of buffer medium is washed out by the waves, it will fall into the lower layer of filling net under its own weight. Then, the excess buffer medium in the lower layer of filling net can be put into the upper layer periodically (the filling net can also be made into a bag shape as needed to prevent the buffer medium from falling out). There will be gaps between the buffer media so as not to affect the normal flow of seawater.

[0022] When waves crash, they first impact the filler net, which is level with the water surface, and come into contact with the buffer medium inside the filler net. Part of the wave is cushioned by the buffer medium inside the filler net, while another part of the wave is blocked by the buffer medium and crashes upwards, and is then blocked and cushioned by the upper filler net (buffer medium) in turn. In the end, the impact force of the wave is completely buffered, thus ensuring the safety of the marine foundation.

[0023] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, any changes made in accordance with the shape and principle of the present invention should be covered within the protection scope of the present invention.
