Description

Technical Field

[0001] This utility model relates to the field of marine ecological restoration technology, and more specifically, to a coral growth device. Background Technology

[0002] Coral reef ecosystems, often referred to as the rainforests of the ocean, possess significant scientific and economic value. When corals are exposed to abnormally high seawater temperatures, climate change, or increased ultraviolet radiation, the corals and their symbiotic zooxanthellae can break down, leading to nutrient loss, loss of color, bleaching, and ultimately, death. High atmospheric carbon dioxide levels causing seawater acidification weaken corals' calcification ability, hindering skeletal formation and reducing juvenile survival rates. When coral reefs die or degrade due to climate or environmental factors, they easily lose their self-recovery capacity, making ecological restoration difficult. Therefore, human conservation and restoration strategies are necessary for their protection and preservation.

[0003] In existing technologies, artificial coral reefs are generally set up on the seabed to help corals restore their normal ecology. Most current artificial coral reefs are made from abandoned ships, cars, concrete sculptures, or steel structures, which are placed in the sea to help the coral reefs repair. However, the attachment effect of this type of artificial coral reef is not good, the repair cycle is long, and it may also contain environmentally unfriendly substances that affect the normal growth of corals, resulting in poor overall repair effect. Utility Model Content

[0004] To overcome the shortcomings of poor attachment effect and long repair cycle of artificial coral reefs in the prior art, this utility model provides a coral growth device that improves coral attachment effect, shortens the coral ecological restoration cycle, and enhances the restoration effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a coral growth device, including: a base, a first reef block and a second reef block respectively connected to the base, and fixing members respectively used to fix the first reef block and the second reef block. The base is provided with a plurality of first communication holes. The first reef block is generally hemispherical. The surfaces of the first reef block and the second reef block are respectively provided with a biomimetic texture attachment layer. The first reef block is provided with a second communication hole, and the second reef block is provided with a third communication hole. The diameter of the first reef block is larger than that of the second reef block, and the height of the first reef block is higher than that of the second reef block.

[0006] The base is set on the seabed, and the first and second reef blocks are fixed to the base by fasteners. The first reef block is larger in both height and diameter than the second reef block to create differentiation. This differentiation, along with their combined arrangement, simulates the natural attachment environment of seabed corals, increasing the likelihood of coral attachment. In actual use, the second reef block is placed around the first reef block. The higher first reef block serves as a sturdy foundation for coral growth and provides a structure for upward attachment or growth, promoting coral colony growth and enhancing the overall structural strength of the coral. In addition, the surfaces of the first and second reef blocks are each equipped with a biomimetic textured attachment layer. This biomimetic texture further enhances the adhesion rate of corals. Simultaneously, the base, the first reef block, and the second reef block are equipped with a first, second, and third communication hole, respectively, to generate upwelling and eddies in the seawater. This creates a flow field effect around the cultivated corals, dispersing suspended matter and sediment, improving the coral's growth environment. It also allows nutrients from the bottom layer to be transported to the corals via the upwelling, increasing the coral's nutrient utilization rate and promoting growth. The first reef block is roughly hemispherical in shape, meaning it is the shape of a sphere cut at any point, with a volume greater than or equal to, and less than, a hemisphere. Fixing components include cable ties, buckles, or bolts. The specific texture of the biomimetic textured attachment layer is designed according to different marine environments and coral species, and can be based on the textures of various coral surfaces or reef surfaces.

[0007] Preferably, the first reef block is provided with multiple planting troughs, and the sides of the planting troughs are provided with multiple vertical grooves that are inclined toward the bottom of the planting troughs.

[0008] Planting troughs are set up to facilitate the planting of coral fragments. Coral fragments can be cut from other live corals or cultivated by oneself. Vertical grooves are set on the side of the planting trough to facilitate coral attachment and increase the chances of coral growth.

[0009] Preferably, the bottom of the planting trough is generally arc-shaped, and the bottom surface of the planting trough is provided with the biomimetic texture attachment layer.

[0010] The bottom of the planting trough is curved and has a biomimetic textured coating layer to further enhance the adhesion of corals.

[0011] Preferably, the second communication port includes a plurality of lower holes evenly distributed at the lower edge of the first reef block, a plurality of middle holes distributed on the middle side of the first reef block, and an upper hole distributed at the top of the first reef block, wherein the diameter of the upper hole is larger than that of the middle holes and the lower holes, respectively.

[0012] The second exchange port includes various types of holes located at different positions on the second reef. The upper hole has the largest diameter, which facilitates the rise of seawater. The middle and lower holes are used to increase the amount of water exchange and the amount of material exchange. Specifically, during fixing, two or more lower holes are selected as connecting holes. The fixing component passes through the selected lower holes and connects to the base, thereby stably fixing the first reef.

[0013] Preferably, the plurality of planting troughs are evenly arranged around the upper hole.

[0014] The planting troughs are evenly spaced around the upper holes, allowing coral fragments to quickly access nutrients and accelerate growth.

[0015] Preferably, the second reef block is disc-shaped and has multiple third communication holes evenly distributed along its edge.

[0016] When fixing, select two or more opposite third AC holes as connection holes. The fastener passes through the selected third AC holes and connects to the base, thereby stably fixing the second reef.

[0017] Preferably, the biomimetic textured attachment layer includes a coral textured attachment layer, a honeycomb textured attachment layer, and a living stone textured attachment layer.

[0018] The specific texture of the coral texture attachment layer is set according to the coral population in the sea area. Specifically, the corresponding coral texture can be obtained by 3D scanning of the coral entity, and then the texture is set on the first or second reef block. The surface with stronger texture and deeper undulation is preferred, which is conducive to coral growth and coverage. The honeycomb texture attachment layer is a texture similar to a honeycomb or honeycomb, and its uneven surface is also conducive to coral attachment. The live rock texture attachment layer is set with reference to the surface texture of live rocks on the seabed, which is also conducive to coral attachment.

[0019] Preferably, the base includes a grid plate, a plurality of support columns respectively connected to the grid plate, and a plurality of connecting blocks connected to the top of the grid plate. Each connecting block and the grid plate is provided with a connecting hole, and the fixing member is connected to the grid plate through the connecting hole.

[0020] The gap between the grid bars on the grating plate is the first exchange hole. The support column is used to support the grating plate. The connecting block is used to connect with the first reef or the second reef. Specifically, the connecting block and the grating plate are respectively provided with connecting holes. After the fixing block passes through the lower hole in the first reef or the third exchange hole in the second reef, it connects with the connecting hole to fix the first reef or the second reef. The specific connection methods include pin connection or threaded connection. When the pin connection is set, the fixing part is various locking pins. When the threaded connection is set, the fixing part is bolt.

[0021] Preferably, the grating plate is generally disc-shaped with radial grating bars, and the grating plate is provided with multiple reinforcing rings of different widths in annular shape. The connecting blocks are arranged in groups, and groups of connecting blocks are provided at the center of the base and between the reinforcing rings.

[0022] Reinforcing rings are installed to ensure the overall stability of the base and prevent the base from shaking and affecting coral growth. As mentioned above, in order to ensure the connection of the first or second reef block is stable, at least two connection points should be selected. Therefore, the connection blocks are set up in groups and used in groups.

[0023] Preferably, the grille is provided with multiple circular positioning rings, and the group of connecting blocks are respectively disposed on the circular positioning rings.

[0024] The circular positioning ring is designed to facilitate the confirmation of the position of the connecting block. When it is necessary to add the first or second reef block after a period of cultivation, it is convenient to quickly locate and fix the first or second reef block underwater.

[0045] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0046] Example 1

[0047] like Figure 1-4 As shown, a coral growth device includes: a base 1, a first reef block 2 and a second reef block 3 respectively connected to the base 1, and fixing members 4 for fixing the first reef block 2 and the second reef block 3 respectively. The base 1 is provided with a plurality of first communication holes 5. The first reef block 2 is generally hemispherical. The surfaces of the first reef block 2 and the second reef block 3 are respectively provided with biomimetic textured attachment layers. The first reef block 2 is provided with a second communication hole 6, and the second reef block 3 is provided with a third communication hole 7. The diameter of the first reef block 2 is larger than that of the second reef block 3, and the height of the first reef block 2 is higher than that of the second reef block 3.

[0048] The base 1 is set on the seabed, and the first reef block 2 and the second reef block 3 are fixed to the base 1 by fasteners 4. The first reef block 2 is larger in both height and diameter than the second reef block 3 to create differentiation. This differentiation, along with the combined arrangement of the first and second reef blocks 2 and 3, simulates the natural attachment environment of seabed corals, increasing the likelihood of coral attachment. In actual use, such as... Figure 1As shown, the second reef block 3 is placed around the first reef block 2. The first reef block 2 is higher, serving as a solid foundation for coral growth and providing a structure for coral to attach or grow upwards, which is more conducive to the colony growth of corals and also enhances the overall structural strength of the corals. Furthermore, the surfaces of the first reef block 2 and the second reef block 3 are respectively provided with biomimetic texture attachment layers. By setting biomimetic textures, the adhesion probability of corals is further enhanced. At the same time, the base 1, the first reef block 2, and the second reef block 3 are respectively provided with a first communication hole 5, a second communication hole 6, and a third communication hole 7, which are used to generate upwelling and eddies of seawater, creating a flow field effect around the cultivated corals, dispersing suspended matter and sediment around the cultivated corals, improving the growth environment of the corals, and allowing nutrients from the bottom layer to be transported to the corals through the upwelling, improving the utilization rate of nutrients by the corals and promoting coral growth. The first reef block 2 is generally hemispherical. Hemispherical refers to the shape of a sphere after being cut at any position, and its volume is greater than or equal to or less than a hemisphere. The fastener 4 uses cable ties, buckles or bolts. The specific texture of the biomimetic texture attachment layer is set according to different marine environments and different coral species. It can be set as the texture of the surface of various corals or the texture of the surface of various reefs, etc.

[0049] like Figure 4 As shown, when the fastener 4 uses a snap-fit, a self-locking snap-fit ​​is selected. Simply insert the fastener 4 to achieve self-locking fixation.

[0050] The beneficial effects of this embodiment are as follows: Based on the specific conditions of the seabed, any number of first reef blocks 2 and second reef blocks 3 can be installed on the base 1. The first reef blocks 2 and second reef blocks 3 have differences in diameter and height. At the same time, the surfaces of the first reef blocks 2 and second reef blocks 3 are respectively provided with biomimetic textured attachment layers, which can imitate the attachment environment of various corals, fully improve the attachment probability of corals, improve the attachment effect of corals, and improve the ecological restoration effect of corals.

[0051] Example 2

[0052] This embodiment further defines the features of Embodiment 1, and its difference from Embodiment 1 lies in:

[0053] like Figure 2-3 As shown, the first reef block 2 is provided with multiple planting troughs 8, and the sides of the planting troughs 8 have multiple vertical grooves inclined towards the bottom of the planting troughs 8. The bottom of the planting troughs 8 is generally arc-shaped, and the bottom surface of the planting troughs 8 is provided with a biomimetic textured attachment layer. The second communication port 6 includes multiple lower holes 9 evenly arranged at the lower edge of the first reef block 2, multiple middle holes 10 arranged on the middle side of the first reef block 2, and an upper hole 11 arranged at the top of the first reef block 2. The diameter of the upper hole 11 is larger than that of the middle holes 10 and the lower holes 9, respectively. The multiple planting troughs 8 are evenly arranged around the upper hole 11. Figure 4-9As shown, the second reef block 3 is generally disc-shaped, and multiple third communication holes 7 are evenly distributed along its edge. Figure 2-9 As shown, the biomimetic textured attachment layer includes a coral textured attachment layer 18, a honeycomb textured attachment layer 19, and a living stone textured attachment layer 20.

[0054] Planting trough 8 is designed to facilitate the planting of coral fragments, which can be taken from other live corals or cultivated independently. Vertical grooves on the sides of planting trough 8 facilitate coral attachment and increase the chances of coral growth. The bottom of planting trough 8 is curved and features a biomimetic textured attachment layer, further enhancing the coral's adhesion. The second communication port 6 includes various types of holes located at different positions on the second reef block 3. The upper hole 11 has the largest diameter, facilitating seawater rise, while the middle hole 10 and lower hole 9 are used to increase water and material exchange. Specifically, during fixing, two or more corresponding lower holes 9 are selected as connecting holes. The fixing member 4 passes through the selected lower holes 9 and connects to the base 1, thus stably securing the first reef block 2. Planting trough 8 is evenly distributed around the upper hole 11, allowing the coral fragments to quickly access nutrients and accelerate growth. During fixation, two or more corresponding third communication holes 7 are selected as connection holes. The fixing piece 4 passes through the selected third communication holes 7 and connects to the base 1, thereby stably fixing the second reef block 3. The specific texture of the coral texture attachment layer 18 is set according to the coral population in the sea area. Specifically, the corresponding coral texture can be obtained by 3D scanning of the coral entity, and then the texture is set on the first reef block 2 or the second reef block 3. The surface with stronger texture and deeper undulation is preferred, which is conducive to the growth and coverage of coral. The honeycomb texture attachment layer 19 is a texture similar to a honeycomb or honeycomb, and its uneven surface is also conducive to coral attachment. The live rock texture attachment layer 20 is set with reference to the surface texture of the live rock on the seabed, which is also conducive to coral attachment.

[0055] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0056] Example 3

[0057] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0058] like Figure 10-12As shown, the base 1 includes a grid plate 12, multiple support columns 13 connected to the grid plate 12, and multiple connecting blocks 14 connected to the top of the grid plate 12. Both the connecting blocks 14 and the grid plate 12 have connecting holes 15. The fastener 4 is connected to the grid plate 12 through the connecting holes 15. The grid plate 12 is generally disc-shaped with radial grid bars. Multiple reinforcing rings 16 of varying widths and in annular shape are provided on the grid plate 12. The connecting blocks 14 are arranged in groups, with groups of connecting blocks 14 located at the center of the base 1 and between the reinforcing rings 16. Multiple circular positioning rings 17 are provided on the grid, and the groups of connecting blocks 14 are respectively positioned on the circular positioning rings 17.

[0059] The gaps between the grid bars on the grid plate 12 are the first communication holes 5. The support column 13 is used to support the grid plate 12. The connecting block 14 is used to connect with the first reef block 2 or the second reef block 3. Specifically, both the connecting block 14 and the grid plate 12 are provided with connecting holes 15. After the fixing block passes through the lower hole 9 in the first reef block 2 or the third communication hole 7 in the second reef block 3, it connects with the connecting hole 15, thereby fixing the first reef block 2 or the second reef block 3. The specific connection methods include pin connection or threaded connection. When setting the pin connection, the fixing part 4 is various locking pins. When setting the threaded connection, the fixing part 4 is a bolt. The reinforcing ring 16 is set to ensure the overall stability of the base 1 and prevent the base 1 from shaking and affecting coral growth. As mentioned above, in order to ensure the connection of the first reef block 2 or the second reef block 3 is stable, at least two connection points are selected. Therefore, the connecting blocks 14 are set in groups and used in groups. The circular positioning ring 17 is set to facilitate the confirmation of the position of the connecting block 14. When it is necessary to add the first reef block 2 or the second reef block 3 after a period of cultivation, it is convenient to quickly locate and fix the first reef block 2 or the second reef block 3 underwater.

[0060] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0061] Example 4

[0062] Based on Example 1, Example 2, or Example 3, Example 1, Example 2, or Example 3 are further defined, with the following differences:

[0063] In this embodiment, both the first reef block 2 and the second reef block 3 are made of pollution-free materials, including but not limited to epoxy resin adhesive, oyster shell powder, and ceramic powder. The first reef block 2 and the second reef block 3 are fabricated using 3D printing technology and silicone molds. First, scanned textures are incorporated into the first reef block 2 and the second reef block 3. Then, master molds for the first reef block 2 and the second reef block 3 are created using 3D printing. Molds are then made using these master molds. Oyster shell powder and / or ceramic powder are added according to the curing characteristics of the epoxy resin adhesive to form a mixed slurry. This mixed slurry is poured into the mold to form the substrate. Finally, an electronic universal pressure testing machine is used to test the compressive strength of the cultivation base to meet the strength requirements for underwater foundation construction.

[0064] In this embodiment, the target corals are fragmented coral branches from the sea area. These coral fragments are rescued in natural marine environments and adhered to the surface of the first reef block 2 or the second reef block 3 using Alon glue, or fixed in the planting tank 8. They are then allowed to rest in an indoor aquarium until acclimatized, and then quickly transferred to the coral nursery planting area using cable ties and underwater adhesive. After transplanting the coral seedlings, recording and subsequent maintenance are necessary. The corals to be planted are photographed and registered, and coral tags are assigned according to the number and species. Divers then transfer the corals and their corresponding tags to the planting area. After each coral is planted, a coral tag is attached next to it for numbering and recording. Later, the coral growth status is observed through diving, and maintenance is carried out, removing sea urchins and crown-of-thorns starfish, which are detrimental to the coral reef ecosystem, to improve the coral survival rate.

[0065] In this implementation method, the target coral skeletal texture coral cultivation substrate structure is the surface structure of native or dominant species of orange-yellow coral, horned honeycomb coral, and natural live rock surface structures in the target sea area, such as... Figure 2-5 As shown, the first reef block 2 and part of the second reef block 3 are covered with a honeycomb-textured coating layer 19; as Figure 6-7 As shown, part of the second reef block 3 uses a coral textured attachment layer 18, which is the surface texture of orange-yellow coral; as Figure 6-7 As shown, some of the second reef blocks 3 are covered with a living rock textured layer 20.

[0066] Major corals typically prefer surface grooves and depressions on the base, while coral larvae also like to settle on rough-textured tiles. The textured surface of the living rock helps mimic the growth of corals on natural reefs.

[0067] Oyster shells contain a large amount of calcium carbonate, similar in properties to stony coral skeletons. They effectively increase the calcium carbonate content of artificial reef bases, providing a calcium source for coral reef construction, building a reef framework to withstand strong winds and waves, providing a hard substrate for coral polyps to attach and grow, enhancing the efficient energy flow of the coral reef ecosystem, and maintaining the efficient material cycle of the coral reef ecosystem. The method is simple, quick, and inexpensive, and has wide applications in restoring and maintaining the diversity and stability of coral reef ecosystems.

[0068] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1, Embodiment 2, or Embodiment 3.

[0069] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
