[0044] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0045] Embodiment 1:

[0046] like Figure 1 , Figure 2 As shown, the embodiment of the present application provides a reef structure, including a frame body 1, an artificial fish reef 2 and a coral cultivation module 3. Among them, a first connecting component 4 is provided on the artificial fish reef 2, a second connecting component 5 is provided on the frame body 1, the first connecting component 4 cooperates with the second connecting component 5, and the artificial fish reef 2 is detachably connected to the frame body 1 through the first connecting component 4 and the second connecting component 5. A third connecting component 6 is provided on the coral cultivation module 3, a fourth connecting component 7 is provided on the frame body 1, the third connecting component 6 cooperates with the fourth connecting component 7, and the coral cultivation module 3 is detachably connected to the frame body 1 through the third connecting component 6 and the fourth connecting component 7.

[0047] Coral planting is a method aimed at restoring and protecting the coral reef ecosystem. Corals are planted by artificial means to promote the growth and recovery of coral reefs. In this embodiment, since the artificial fish reef 2 and the coral cultivation module 3 are both detachably connected to the frame body 1, the reef structure is easy to assemble and disassemble, as well as to transport. Corals can be planted on the coral cultivation module 3. The embodiment of the present application realizes the combination of artificial fish reefs 2 and coral reef planting by installing artificial fish reefs 2 and coral cultivation modules 3 on the frame body 1. The presence of corals can improve water quality and enrich the types of organisms in the waters where the fish reefs are located, thereby providing food for the fish schools that settle on the artificial fish reefs 2.

[0048] The frame body 1 of this embodiment may be provided with a fish nest hole 21 so that the frame body 1 itself can also play a role similar to that of an artificial fish reef 2. The artificial fish reef 2 may be made of environmentally friendly recycled plastic to avoid affecting water quality. The artificial fish reef 2 also has a fish nest hole 21.

[0049] In one embodiment, in order to realize the detachable connection between the artificial fish reef 2 and the coral culture module 3 and the frame body 1, the first connecting component 4 and the third connecting component 6 are both connecting buckles, the second connecting component 5 and the fourth connecting component 7 are both connecting slots, and the connecting buckles match the connecting slots. The first connecting component 4 and the third connecting component 6 have the same structure, and the second connecting component 5 and the fourth connecting component 7 have the same structure, so as to facilitate the processing and manufacturing of the frame body 1, and also facilitate the detachable connection between the artificial fish reef 2 and the coral culture module 3 and the frame body 1.

[0050] In one embodiment, if Figure 4 , Figure 6 , Figure 8 As shown, only the artificial reef 2 can be installed on the frame body 1, and the artificial reef 2 is located inside the frame body 1. In another embodiment, as shown in FIG. Figure 1 As shown, an artificial fish reef 2 and a coral cultivation module 3 can also be installed on the frame body 1 at the same time, the artificial fish reef 2 is installed inside the frame body 1, and the coral cultivation module 3 is installed on the upper surface of the frame body 1, and the coral cultivation module 3 is located above the artificial fish reef 2. In other embodiments, such as Fig.10 As shown, the coral cultivation module 3 may also be installed only on the frame body 1 , and the coral cultivation module 3 is installed on the upper surface or the lower surface of the frame body 1 .

[0051] Preferably, the frame body 1 is a cube structure or a rectangular parallelepiped structure. The four lateral support rods at the bottom of the frame body 1 and the four lateral support rods at the top of the frame body 1 are provided with connecting slots. The four surfaces at the bottom of the artificial fish reef 2 are provided with connecting buckles, and the four sides of the coral cultivation module 3 are also provided with connecting buckles. The four connecting buckles of the artificial fish reef 2 are connected to the four connecting buckles at the bottom of the frame body 1, and the four connecting buckles of the coral cultivation module 3 can be connected to the four connecting buckles at the top or bottom of the frame body 1.

[0052] In one embodiment, as 1 and Figures 4 to 9 As shown, the cross section of the artificial reef 2 can be square, trapezoidal, triangular or semicircular. The cross section of the artificial reef 2 is not limited to the above four shapes, and the cross section of the artificial reef 2 can also be other shapes.

[0053] The coral cultivation module 3 is made of degradable bioceramic material, which takes advantage of the biocompatibility, bioactivity and degradability of the degradable bioceramic material to provide a favorable environment for the growth of corals. As time goes by, the coral cultivation module 3 will gradually degrade and completely integrate the corals into the seabed environment. The degradable bioceramic material can be calcium carbonate bioceramic. The planting technology of corals on the coral cultivation module 3 is an existing technology, which can achieve the planting of corals.

[0054] In one embodiment, if Figure 2 , 3 As shown, when the reef structure is used, a plurality of reef structures are generally spliced ​​and combined for use. In order to facilitate the upper and lower splicing of the reef structure, a first splicing piece 8 is provided on the top of the frame body 1, and a second splicing piece 9 is provided on the bottom of the frame body 1. The first splicing piece 8 matches the second splicing piece 9. When two reef structures are spliced ​​up and down, the splicing can be achieved through the first splicing piece 8 and the second splicing piece 9.

[0055] Specifically, the first splicing piece 8 is a splicing column, which protrudes from the top of the frame body 1, and the second splicing piece 9 is a splicing groove, which is recessed from the bottom of the frame body 1 to the middle of the frame body 1. When splicing two frame bodies 1, the splicing column can be inserted into the splicing groove. Preferably, the cross-sections of the splicing column and the splicing groove can be a cross-shaped structure. The number of the first splicing piece 8 and the number of the second splicing piece 9 are both four, and the four first splicing pieces 8 and the four second splicing pieces 9 are all located at the four corners of the frame body 1.

[0056] Since the artificial fish reef 2 and the coral cultivation module 3 are both detachably connected to the frame body 1, the artificial fish reef 2 and the coral cultivation module 3 can be removed from the frame body 1 and transported independently, or the artificial fish reef 2 and the coral cultivation module 3 can be installed with the frame body 1 and transported together.

[0057] In order to facilitate the left-right and front-back splicing of the reef structure, the reef structure further includes a first fixing member 10, and a second fixing member 11 is provided on the side of the frame body 1, and the first fixing member 10 and the second fixing member 11 are detachably connected. Preferably, the first fixing member 10 is a fixing rod, and the second fixing member 11 is a fixing hole, and the fixing rod matches the fixing hole.

[0058] When the two reef structures are spliced ​​left and right or front and back, the fixing rods can be respectively inserted into the fixing holes on the sides of the two frame bodies 1, thereby realizing the left and right splicing of the two reef structures. In this embodiment, there can be multiple first fixing members 10, and multiple second fixing members 11 can be provided on each side of the frame body 1, and the multiple second fixing members 11 are respectively located at different positions on the same side, so that the two frame bodies 1 are spliced ​​more firmly when spliced.

[0059] In one embodiment, if Fig.11 As shown, the reef structure further comprises a protection net 12, which is mounted on the outer surface of the frame body 1. The protection net 12 may be a flexible protection net.

[0060] The reef structure of the present application can provide an ideal habitat for various marine organisms by arranging a detachable artificial fish reef 2 and a coral cultivation module 3 on the frame body 1, attracting more species and numbers of fish and other marine organisms, and providing them with a shelter, thereby effectively improving the marine ecological environment.

[0061] Embodiment 2:

[0062] The present embodiment is described in detail below with reference to the first embodiment:

[0063] like Figures 12 to 14 As shown, an embodiment of the present application provides an ecological reef system, comprising at least two reef structures as described in Embodiment 1, and adjacent reef structures are detachably connected.

[0064] The artificial fish reef 2 and the coral cultivation module 3 are detachably connected to the frame bodies 1 of the two reef structures; or, the artificial fish reef 2 is detachably connected to one of the frame bodies 1, and the coral cultivation module 3 is detachably connected to the other frame body 1.

[0065] When assembling multiple reef structures, the reef structures arranged vertically are spliced ​​together by the first splicing piece 8 and the second splicing piece 9, and the reef structures arranged horizontally or front and back are spliced ​​together by the first fixing piece 10 and the second fixing piece 11. In actual use, they can be assembled into different forms according to different usage functions.

[0066] like Fig.12As shown, the ecological reef system can be assembled from multiple reef structures. The uppermost and lowermost frame bodies 1 are only equipped with coral culture modules 3 for planting coral reefs to attract fish and marine life. The frame body 1 in the middle can be equipped with artificial fish reefs 2 to provide a place for fish to reproduce, grow, feed and shelter from enemies. The artificial fish reefs 2 can be set in different shapes, and the sizes of the fish nest holes 21 thereon can also be different, so as to meet the needs of different species.

[0067] like Fig.13 As shown, the ecological reef system is also assembled from multiple reef structures, wherein an artificial fish reef 2 is installed on part of the frame body 1, and a coral cultivation module 3 is installed on part of the frame body 1. The middle part of the assembled ecological reef system is a hollow structure. The ecological reef system of the above-mentioned assembled structure can be set near tourist facilities to improve the seabed landscape, and diving enthusiasts can pass through the hollow structure reserved in the middle.

[0068] like Fig.14 As shown, the ecological reef system is also assembled from multiple reef structures, wherein an artificial fish reef 2 is installed on the partial frame body 1, and a coral cultivation module 3 is installed on the partial frame body 1. The middle of the multiple reef systems forms a breeding area. After the protective net 12 is installed on the frame body 1 located on the outside, aquatic products can be cultured in the breeding area. The artificial fish reef 2 and the coral cultivation module 3 can improve the water quality of the breeding area; or the ecological reef system can be used as a leisure sea fishing area.

[0069] The ecological reef system of the present application improves the marine ecological environment, provides a habitat for marine life and improves the seabed landscape. The modular design makes the structure easy to assemble and disassemble, and can be expanded, adjusted and transported as needed.

[0070] To a certain extent, it can avoid the negative impact that traditional artificial coral reefs and artificial fish reefs2 may have on the marine environment. In certain cases, invasive alien species can use the ecological reef system to spread to new places, and may also attract fish away from nearby natural coral reefs. The modular design of the structure can be dismantled and transported in time when such problems occur, avoiding greater impact on the ecological environment.

[0071] The ecological reef system of the present application integrates artificial fish reefs 2 and coral reefs. Compared with a single artificial fish reef 2 or artificial coral reef, the ecological reef system is more likely to attract fish and marine life. The modular design and flexible assembly method enable the structure to effectively improve the seabed landscape and be used for underwater sightseeing while performing ecological restoration. The structure can be used for aquaculture or recreational sea fishing after a flexible protective net 12 is installed on the outer frame. The coral reefs and fish reefs inside the structure can improve the water quality of the breeding area and provide food for fish and other marine life.

[0072] Embodiment three:

[0073] The present embodiment is described in detail below with reference to the second embodiment:

[0074] The embodiment of the present application provides a method for constructing an eco-reef system, which is used to construct the eco-reef system as described above, and the method comprises the following steps:

[0075] S1: Determine the deployment sea area, and determine the number and assembly method of reef structures in the ecological reef system based on the information of the deployment sea area.

[0076] Before deployment, it is necessary to conduct a marine environmental analysis of the deployment area, select the geometric shape of the artificial fish reef 2, the size of the fish nest hole 21, the variety of artificially planted corals and other elements based on the environmental characteristics of the planned deployment area and the type of marine life, and preliminarily formulate the assembly plan of the required main structure.

[0077] Then the structural load and the flow field of the surrounding waters are calculated. The forces on the structure in the water can be calculated by referring to the study of the flow field and force characteristics of artificial reef 2 under the action of waves and currents by Mitsuru Nakamura in 1991 and Xianglu Huang in 1992. The specific calculation method is as follows:

[0078] The water flow velocity in the release area can be regarded as the superposition of tidal velocity and wave velocity:

[0079]

[0080] u=u 0 +u m sinθ

[0081] where u m is the amplitude; H is the wave height; D is the height of the top of the structure from the seabed; L is the wavelength; T is the period; h is the water depth of the sea area where the assembled structure is deployed; θ is the wave direction angle; u 0 The speed of the current.

[0082] The fluid forces acting on the ecological reef system on the seabed include drag force and additional mass force:

[0083]

[0084] Among them C d is the drag coefficient, generally taken as 1.25; ρ is the seawater density; A is the headwater area of ​​the structure; C m is the additional mass force coefficient, which is generally taken as 1; V is the volume of the structure. The water flow and wave parameters and seawater density in the above formulas are obtained through on-site measurements in the deployment waters.

[0085] When determining the assembly plan, the above calculation results should be compared with the static friction and gravity torque of the ecological reef system on the seabed to ensure that the structure will not slip, roll or deform on the seabed.

[0086] The maximum static friction force of the ecological reef system on the seabed can be calculated according to the following formula:

[0087] f=V(σ-ρ)g·μ

[0088] Among them, σ is the average density of the structure, and μ is the static friction coefficient of the contact surface between the bottom of the structure and the seabed. The specific value can be obtained through experimental measurement. In order to ensure that the structure does not slip, it should be ensured that the fluid force F exerted on the structure on the seabed is less than the maximum static friction f.

[0089] In order to ensure that the structure of the ecological reef system does not roll over or deform, it is also necessary to ensure that the combined moment of gravity and buoyancy is greater than the moment generated by the fluid force F. Due to the complex geometric shape of the structure, it is difficult to accurately calculate the magnitude of the moment generated by the fluid force F through the formula. Numerical simulation or model tests in the laboratory can be used for relevant calculations and verifications.

[0090] The impact of the ecological reef system on the flow field in the surrounding waters after its deployment (including the upwelling, back vortex and internal vortex generated by the artificial reef 2) is directly related to its effect of attracting marine life and improving the marine ecological environment. However, the relevant calculations are relatively complex, and numerical simulation and other methods can be used to analyze such factors and determine the best structural type and assembly method.

[0091] S2: a prefabricated reef structure frame body 1, an artificial fish reef 2 and a coral culture module 3, and corals are planted on the coral culture module 3. Corals are planted on the prefabricated coral culture module 3 by using techniques such as fragment cultivation or fragment transplantation.

[0092] S3: Assembling the frame body 1, the artificial fish reef 2 and the coral cultivation module 3 according to the determined assembly method, and forming an ecological reef system after assembly.

[0093] S4: Deploy the ecological reef system to the seabed of the designated deployment area.

[0094] The components of the ecological reef system of the present application can be prefabricated in the factory in advance, and can be directly assembled and put into use after being prefabricated. Since the artificial fish reef 2 and the coral culture module 3 are both detachably connected to the frame body 1, and the adjacent frame bodies 1 can also be detachably connected to each other, the ecological reef system is easy to assemble and disassemble, and easy to transport.
