Description

Technical Field

[0001] The utility model relates to the technical field of island reef coral sand beach erosion protection, in particular to an eco-friendly island reef coral sand beach erosion protection fence. Background Art

[0002] Coastal coral sand is not only a vital marine resource for islands and reefs, but also a crucial component of the nation's marine blue territory. In recent years, the deterioration of the global extreme marine environment has exacerbated the erosion and loss of coral sand on islands and reefs. Therefore, there is an urgent need to improve relevant protection technologies to address the increasing threat of erosion disasters. Currently, the main technologies for preventing and controlling the soil and water loss of coral sand on islands and reefs in the field of beach erosion protection technology include artificial coastal protection projects, mangrove coastal shelterbelts, and coastline protection fences.

[0003] Artificial coastal protection projects use engineering methods, such as constructing breakwaters, wave-breaking walls, and underwater dikes, as well as deploying wave-breaking blocks, to mitigate and prevent the erosion of coral sands by extreme ocean dynamics on coral reef coastlines. However, according to national standards, these artificial coastal protection projects often require long-term construction preparation, mature construction conditions, detailed construction plans, and high construction costs. These construction requirements are often difficult to meet on remote islands and reefs, making their implementation generally less feasible. Even when construction conditions and resources are met, these artificial protection projects can maintain the stability of coral sands in specific coastal areas for a long time. However, their construction not only significantly impacts the pristine ecological environment of islands and reefs, but their implementation often creates a problem, exacerbating the negative impact of coral sand erosion and siltation in other coastal areas. This contradicts my country's philosophy of sustainable and ecological island and reef management.

[0004] Mangroves are known as the "guardians of the coast." Establishing mangrove coastal shelterbelts not only protects against wind and waves but also consolidates sand, stores carbon, and maintains biodiversity, making them an ideal ecological solution for preventing coastal erosion on islands and reefs. However, mangroves have an extremely long growth cycle; it can take over 70 years for a single mangrove seedling to grow into a mature, stable tree. Furthermore, mangroves are highly sensitive to climate, soil quality, environmental pollution, pests and diseases, and are easily damaged by abnormally high sea temperatures, typhoon storm surges, seawater pollution, and the invasion of pests and diseases. Therefore, cultivating a mature, functional mangrove forest is difficult, costly, and challenging. Limited by slow construction times, high maintenance costs, and fragile survival rates, mangrove coastal shelterbelts currently remain an unviable and effective solution for preventing erosion on coral sandbanks on islands and reefs.

[0005] Coastline protection fences typically consist of 1.5-3 meter tall vertical poles erected every 2-5 meters. These are then laid along the coastline of islands and reefs using a dense mesh of metal or plastic mesh with an aperture of approximately 5-10 centimeters, tied together or welded together. This method is relatively inexpensive compared to coastal protection projects, and the fences effectively slow the seaward transport of coral sand, stabilizing the coral sand along the island and reef coastlines to a certain extent. However, coastline protection fences have a very poor aesthetic appeal. With the increasing tourism development of my country's islands and reefs in recent years, these fences have somewhat diminished the scenic beauty of these island and reef coastlines. Furthermore, the apertures of these fences are too small. As the ecological environment of islands and reefs recovers and improves, many sea turtles are flocking to these islands to lay their eggs. These fences significantly interfere with the turtles' access to the islands for laying eggs, making it more difficult for hatchlings to return to the sea, thus hindering the restoration of biodiversity on the islands and reefs. In addition, many protective fences are made of plastic materials to reduce costs. Under the influence of long-term erosion by waves and the high temperature and high salt in the open sea, these plastics are easily damaged and turned into plastic waste, which remains in the coastal areas of islands and reefs or is transported to the nearshore area, thereby destroying the marine ecological environment near the islands and reefs.

[0006] In summary, the existing technologies for preventing and controlling soil erosion of coral sand on islands and reefs, and artificial engineering protection methods, not only consume a lot of construction costs, but also have low applicability to offshore islands and reefs; while the use of mangroves for coastal protection is eco-friendly, it has a long construction cycle, an extremely low survival rate, and high maintenance costs; the landscape integration through coastline protection fences is poor, and the potential impact on marine life and the marine environment is large, which does not meet the development needs of the era of island and reef ecological development and green construction. Utility Model Content

[0007] The utility model provides an eco-friendly island reef coral sand coastal erosion protection fence, which can reduce and prevent the risk of coral sand land loss caused by island reef coral sand under extreme ocean dynamics.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] An island reef coral sand coastal erosion protection fence, comprising:

[0010] The main support rod has a fence plug-in base at the bottom;

[0011] Two anti-corrosion bamboo fences are symmetrically arranged on the left and right wings of the main support rod.

The top of the main rod is vertically connected to the telescopic cross rod and the bottom of the main rod is provided with a fence plug-in base. Several folding components are provided between two adjacent main rods or between adjacent main rods and the main support rod.

[0012] As described above, the island reef coral sand coastal erosion protection fence further comprises: a folding rod cross-connected by a folding rotating shaft, and the two ends of the folding rod are respectively arranged on the two adjacent main rods or on the adjacent main rods and the main support rod.

[0013] The island reef coral sand coastal erosion protection fence as described above further includes storage connecting snaps, which include two mother snaps and two child snaps used in combination. The two mother snaps are respectively arranged on the top and bottom of the outer main pole of one group of the anti-corrosion bamboo fences, and the two child snaps are respectively arranged on the top and bottom of the outer main pole of another group of the anti-corrosion bamboo fences.

[0014] The island reef coral sand coastal erosion protection fence as described above further includes a splicing connector jack and a splicing connector used in combination, the splicing connector jack is arranged on the outer main pole of one group of the anti-corrosion bamboo fences, and the splicing connector is arranged on the outer main pole of another group of the anti-corrosion bamboo fences.

[0015] The island reef coral sand coastal erosion protection fence as described above further includes a fence angle limiter and the fence angle limiter is arranged between the two anti-corrosion bamboo fences.

[0016] The island reef coral sand coastal erosion protection fence as described above further includes a fence handle, which is arranged on the main support rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This utility model is manufactured using low-cost materials, making it economical for regional protective deployment and suitable for large-scale deployment. Furthermore, it can be deployed by a single person, reducing labor costs during the implementation phase. Furthermore, maintenance costs are low; even if completely damaged, only the damaged fence needs to be replaced, making it easy to replenish and replace.

[0022] 2. This utility model uses natural materials, such as bamboo, to reduce potential environmental and microplastic pollution at the source. Bamboo is self-degradable, and even if damaged, it poses no threat to the ecosystem and produces no plastic waste. Furthermore, the fence design fully considers the ecological needs of sea turtles for egg-laying and migration, consistent with the concept of maintaining and promoting biodiversity on islands and reefs.

[0023] 3. The utility model fully considers the characteristics of poor sorting and coarse particle size of island reef coral sand, and adopts a large-aperture fence grid. While consolidating the island reef coral sand, it does not cause erosion and siltation problems in other adjacent areas. The large-aperture design allows strong ocean power to transport sediments inland, but the weaker backflow will be further weakened under the protection of the fence, retaining the coral sand that would otherwise be eroded and lost.

[0024] 4. This utility model offers excellent landscape benefits. The natural bamboo fence does not affect the coastal landscape. Furthermore, the design allows for the free combination and connection of multiple fences. Users can not only deploy coastal erosion protection functions, but also customize the structure according to landscape requirements. Furthermore, thanks to the rapid assembly and deployment advantages of this utility model, it can also be quickly deployed in the event of major marine disaster warnings to mitigate coastal coral sand erosion losses caused by typhoons and other events.

[0042] During the actual deployment of coastal erosion protection measures for island reefs and coral sand, the utility model is initially in a stowed and compacted state. Operators can then transport the utility model in batches to the target coastline. Upon arrival, personnel must first unfasten the upper and lower storage connection snaps (female snap 1) and the lower snaps (female snap 14). Then, they must reversely untie the two storage connection ropes 13, bringing the fence into a largely unfastened state. The operator then grasps the fence handles 10 and inserts the main support rods 9 into the coral sand, ensuring that the fence plug-in base 6 is fully inserted into the sand. As needed, the operator can step on the windbreak auxiliary pins 11 to ensure that the main support rods 9 are fully and securely upright. The operator can then gently lift the splicing connectors 15 out of the splicing connector receptacles 3, fully unfastening the fence. The operator can then unfold the telescopic crossbars 7. The opening angle of the fence should be carefully adjusted based on the local coral sand grain size, wave intensity, and erosion control expectations. A default opening angle of 5 degrees is generally recommended. Next, the operator extends the telescopic crossbar 7 to one side, deploying all of the anticorrosive bamboo fences (main poles 2) on that wing. The corresponding anticorrosive bamboo fences (folding poles 4) then fold and rotate the pivots 5 to form stable, prismatic and triangular shapes. Once fully deployed, the operator inserts the fence plug-in bases 6 below the anticorrosive bamboo fences (main poles 2) into the coral sand to stabilize the fences on that wing. Once completed, the operator repeats the deployment process for the other wing, fully deploying the fences. At this point, the operator manually locks the fence angle limiter 12. Finally, the operator manually activates the solar-powered warning light 8, providing a nighttime warning to prevent trespassers. When splicing multiple fences, the operator inserts the splicing connector 15 on the right wing of the middle fence into the splicing connector jack 3 on the left wing of the right fence. The splicing connector jack 3 on the left wing of the middle fence is then used to insert the splicing connector 15 on the right wing of the left fence. It's recommended that every 5-10 booms be connected with 3-5 gaps between them to allow for adult turtles to come ashore to lay eggs and migrate back to the sea, or for island fishermen to retrieve and launch their boats. When recovering, operators should reverse the above steps. During storage, ensure the booms are protected from insects and corrosion.
