Description

Technical Field

[0001] The utility model belongs to the field of marine ecological restoration, and in particular relates to a trapezoidal glass fiber reinforced plastic reef body used for coral reef ecological restoration. Background Art

[0002] Coral reefs, found in tropical low-latitude oceans, are crucial marine ecosystems that integrate ecological resources, environmental regulation, recreation, coastal protection, national security, mineral and oil production, and science and culture. Known as the "tropical rainforests of the ocean," they are among the most biodiverse and resource-rich ecosystems in the world and play a vital role in the health and sustainable development of human society and the marine ecosystem. However, in recent years, high-intensity human activities have caused extremely severe ecological damage and environmental pollution to the ocean, leading to severe damage to coral reef ecosystems and making their recovery difficult. Healthy, slightly damaged coral reefs can recover naturally over a period of time; however, for some more severely damaged coral reef ecosystems, natural recovery may take hundreds of years, often requiring human intervention to rebuild the ecosystem. This is primarily achieved by constructing artificial reefs and deploying them in damaged areas, or by artificially repairing existing reefs. Artificial reef foundations are beneficial for increasing the complexity of the three-dimensional structure of coral reefs, providing a good and stable habitat and breeding ground for marine life. They also provide a solid base for corals attached or transplanted to artificial reef foundations to avoid the influence of loose substrate, reduce predation by pests, improve survival rates, and accelerate the restoration of coral reef ecosystems. Most of the artificial reefs currently deployed are not strong enough due to different materials and shapes, and are easily broken. They are easily washed away by currents and difficult to track. They are also easily covered by bottom sediments, making them difficult to clean and maintain. In addition, the surface of such reefs is rarely conducive to the design of coral fragment transplantation, and it is difficult to promote the attachment and growth of corals. The growth rate of corals is low, and the restoration of coral reef ecosystems is limited. Utility Model Content

[0003] The purpose of the utility model is to provide a trapezoidal fiberglass reef body for coral reef ecological restoration, so as to solve the technical problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A trapezoidal fiberglass reef body for coral reef ecological restoration includes a top plate and side plates. The top plate is arranged horizontally; two side plates are provided, which are fixedly connected to the left and right sides of the top plate respectively and tilted outward at a certain angle to the top plate; a plurality of through-holes are provided at intervals on the top plate and the side plates.

[0006] Furthermore, a 120° angle is formed between the side panels and the top panel.

[0007] Furthermore, the orifice is a square structure.

[0008] Furthermore, it also includes a support plate; two support plates are horizontally provided, and the two support plates are fixedly connected to the outer sides of the lower ends of the two side plates respectively.

[0009] Furthermore, it also includes a fixing hole; the fixing hole is vertically penetrated and opened on the top surface of the support plate.

[0010] Furthermore, three fixing holes are provided at intervals in the front and rear.

[0011] Furthermore, the top plate, side plates and support plates are made of fiberglass reinforced plastics.

[0012] The working process and principle of this utility model are as follows:

[0013] After investigating and understanding the seabed topography and distribution of marine life in the restoration area, the reefs were transported to the designated sea area by ship for precise positioning and hoisting. After being deployed underwater, staff dived to the seabed to assist in the accurate placement of the reefs. At the same time, steel chisels were inserted into multiple fixing holes to firmly install the reefs on the seabed. After all the reefs were deployed, seedlings with coral fragments were stuck in the holes, or cable ties were passed through the holes to tie the coral branches to the edges of the holes to complete the coral transplantation. Soon, the coral seedlings on the reefs will reproduce and grow to form an artificial coral reef, thereby restoring the coral reef ecosystem.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The utility model forms a ladder-like structure with the top, side, and bottom surfaces, covering the seabed. This structure ensures the stability of the reef structure. The inclined sides of the ladder can mitigate the impact of ocean currents, ensuring that the reef does not tip over or shift, and improving installation stability. The top and side panels are provided with multiple square openings, which can be used to transplant coral fragments or broken branches. The transplantation is stable and not easily washed away by seawater, displaced, or covered by seabed sediments, algae, and other impurities. This improves the survival rate and growth rate of coral seedlings, and facilitates the free entry and exit of various coral reef organisms, allowing them to forage and escape from natural enemies. It also facilitates the flow of ocean currents into the reef to form upwelling, thereby carrying organic matter and a large number of phytoplankton from the bottom to the surface, providing corals and other organisms with a richer source of food and nutrition, promoting their growth and reproduction, and thus repairing the coral reef ecosystem. In addition, the openings can promote the flow of ocean currents into the reef, improve the flow of seawater, ensure the exchange of materials and energy between the reefs, disperse the impact of ocean currents, and increase stability and durability.

[0016] 2. The utility model sets a support plate and opens fixing holes on the support plate. Steel chisels are driven into the fixing holes to fix the reef to the seabed, which makes the reef more stable, promotes the adaptation of the reef to the uneven terrain of the seabed, and greatly enhances its stability in various seabed landforms.

[0017] 3. The trapezoidal reef structure of the present invention not only restores the three-dimensional structure of the coral reef area, but also creates as much ecological area as possible within the minimum unit ocean area. This is not only conducive to the growth and development of coral fragments and the attachment of corals, achieving the aggregation of large numbers of corals, but also provides a habitat, foraging, and reproduction site for marine organisms such as fish and shellfish, preliminarily rebuilding the coral reef ecosystem and improving the biodiversity and primary productivity of the restored sea area.

[0018] 4. The utility model is made of fiberglass, which has the characteristics of light weight, high strength and corrosion resistance. It is easy to transport and deploy, making the reef easy to transport and deploy, and at the same time resistant to seawater corrosion, which can greatly increase the service life of the reef.

[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in this specification are merely provided to help readers gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0025] like Figure 1-4As shown, a trapezoidal fiberglass reef body for coral reef ecological restoration includes a top plate 1 and a side plate 2. The top plate 1 is arranged horizontally, has a thickness of 5 cm, a length and width of 2 m and 1 m respectively, and a height of 70 cm; the side plates 2 are provided with two, which are fixedly connected to the left and right sides of the top plate 1 respectively, and are inclined outward at a certain angle with the top plate 1, so that the top plate 1 and the side plates 2 form a trapezoidal structure with the seabed surface, thereby improving the structural stability of the reef body. At the same time, the inclined side plates 2 of the trapezoidal structure can ensure that the reef body does not tip over or shift, and ensure the installation stability of the reef body on the seabed. The thickness of the side plates 2 is 5 cm, and the length and width are 2 m and 1 m respectively; a plurality of through openings 4 are provided at intervals on the top plate 1 and the side plates 2, and the openings 4 can be used to place seedling trays with coral fragments. At the same time, cable ties can be used to pass through the openings 4 to bundle coral branches on the edges of adjacent openings 4 to achieve the transplantation of coral fragments. In addition, the holes 4 can buffer the energy of the impacting ocean currents, enhance the overall resistance of the reef to rapid ocean currents, and induce ocean currents to pass through these holes 4 to form upward turbulence, bringing food to corals and other marine organisms. At the same time, it can also provide water flow conditions and dissolved oxygen content to promote the growth of coral seedlings.

[0026] The side panels 2 and the top panel 1 form an angle of 120°, so that the top panel 1 and the side panels 2 form an isosceles trapezoidal structure with the seabed, further improving the structural stability.

[0027] The opening 4 is a square structure with a side length of 10 cm. The top plate 1 and the two side plates 2 are each provided with 8 rows and 13 columns, for a total of 104 square openings 4. Since the seedling support is a stepped structure with a larger top and a smaller bottom, the size of the opening 4 is larger than the top surface of the seedling support and smaller than the small surface of the seedling support. After the lower surface of the seedling support passes through the opening 4, the seedling support can be stuck in the opening 4.

[0028] The reef also includes two horizontal support plates 3, each 2 meters long and 10 centimeters wide. Opposite sides of the two support plates 3 are fixedly connected to the lower ends of the two side plates 2. The support plates 3 support the top plate 1 and the side plates 2, allowing the reef to be installed on the seabed.

[0029] The reef also includes a fixing hole 5, which is vertically through the top surface of the support plate and has a diameter of 7 cm. By inserting a steel drill into the fixing hole 5 of the support plate 3, the reef can be fixed to the seabed.

[0030] The fixing holes are spaced apart in front and back and are provided with three of them. By inserting a plurality of steel drills into the plurality of fixing holes 5, the installation stability of the reef body on the seabed can be further improved.

[0031] The top plate 1, side plates 2, and support plates 3 are integrally formed from fiberglass reinforced plastic (FRP). This integrally formed structure allows the reef to withstand greater impact forces, ensuring its service life. FRP is lightweight, strong, and corrosion-resistant, making it easy to transport and deploy. It is also resistant to seawater corrosion, significantly extending the reef's service life. A steel frame can be formed, and the FRP material is solidified onto the steel frame. The steel frame combined with the FRP material further enhances structural strength and durability.

[0032] The working mode of the utility model is:

[0033] After investigating and understanding the seabed topography and distribution of marine life in the restoration area, the reefs are transported to the designated sea area by ship for precise positioning and lifting. After being put into the water, the staff dives to the seabed to assist in the accurate placement of the reefs. At the same time, steel chisels are inserted into the multiple fixing holes 5 on the two support plates 3 to firmly install the reefs on the seabed. After all the reefs are deployed, the seedlings with coral fragments are stuck in the holes 4, or the coral branches are tied to the edges of the holes 4 with cable ties through the holes 4 to complete the coral transplantation. Soon, the coral seedlings of the reefs will reproduce and grow to form an artificial coral reef, thereby realizing the restoration of the coral reef ecosystem.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
