Description
Technical Field
[0001] This utility model relates to the field of marine ecological restoration technology, specifically the design of a multifunctional marine ecological reef base. Background Technology
[0002] As global temperatures continue to rise, coral reefs are facing multiple pressures, including illegal mining, overfishing, and pollution from aquaculture, leading to severe bleaching and degradation. According to authoritative research, 84% of the world's coral reefs are bleaching, and some even face the risk of complete disappearance by the end of this century. Coral reef degradation poses a serious threat to marine life, fisheries resources, coastal safety, and even global climate stability. Therefore, protecting coral reefs and curbing their degradation has become a crucial task for maintaining the balance of the Earth's ecosystem and ensuring sustainable human development.
[0003] At the same time, due to overfishing, marine pollution, climate change, and habitat destruction, fish resources have severely declined, leading to reduced catches, population decreases, biodiversity loss, and severe ecosystem imbalance. Artificial reefs can provide fish with breeding, growth, and refuge from predators, attracting fish to congregate and promoting resource recovery. They are of great significance for restoring my country's marine fish resources and improving the ecological environment, and are a key measure for achieving marine ecological civilization and sustainable fisheries development.
[0004] The core design of existing artificial reef bases focuses only on biological habitats (such as fish hiding and a small number of organisms attaching), without considering the stability of seabed sediment and the needs of coastal slope protection. On the one hand, most reef bases are independent single units or simple spliced structures, and their integration with the seabed is limited to "placement" or shallow embedding. They cannot restrict the lateral flow of seabed sediment through structural design, which leads to easy loss of sediment under the scouring of ocean currents. Utility Model Content
[0005] To address the above technical problems, this utility model proposes a multifunctional marine ecological reef base solution that integrates coral planting, fish habitat, and small organism attachment functions. The reef base unit is embedded in the seabed, effectively resisting seawater impact and tidal influence, and preventing reef base displacement or tilting. The geogrid has a two-dimensional mesh structure, which facilitates seagrass attachment, improves the attachment rate of seagrass and fish eggs, and further reduces seabed sediment loss.
[0006] A multifunctional marine ecological reef base includes a reef base unit, a seabed, and a geogrid. The top of the reef base unit has a growth platform, and coral planting troughs are distributed along the edge of the growth platform. The interior of the reef base unit contains a fish habitat area, and the top of the reef base unit also has perforated holes connecting to the fish habitat area. Several reef base units are embedded in the seabed and arranged closely to form a reef base zone. Multiple reef base zones are spaced apart on the seabed. The geogrid is laid on the seabed between adjacent reef base zones and has mesh openings. The reef base units, embedded in the seabed, act as a sand-stabilizing and slope-protecting element, reducing sediment loss, blocking ocean current erosion of the seabed, and enhancing the restoration and protection of islands and shorelines. The geogrid has a two-dimensional mesh structure, facilitating seagrass attachment. Its pore structure can simulate the porous environment between seagrass plants, adapting to the size of fish eggs, increasing the attachment rate of seagrass and fish eggs, and further reducing seabed sediment loss.
[0007] Furthermore, the reef base unit features a perforated section extending to its bottom, with the lower section embedded in the seabed. The interior of the reef base unit, within the perforated space above the seabed, forms a habitat for fish. This design fully utilizes the internal space of the reef base unit, providing ample habitat for fish. Simultaneously, the embedding of the lower section into the seabed further enhances the stability of the reef base unit on the seabed, preventing displacement due to seawater currents.
[0008] Furthermore, the bottom edge of the reef base unit is equipped with supports that match the shape of the coral planting trough. During transportation, the reef base units can be stacked by the corresponding fitting of the supports with the coral planting trough, which facilitates transportation and improves the stacking stability during transportation. During installation, the supports are inserted into the seabed to enhance the stability of the installation structure and prevent the reef base units from shifting due to ocean currents.
[0009] Furthermore, each reef base zone consists of reef base units arranged in at least two closely spaced rows, with a minimum spacing of two reef base units between adjacent reef base zones. Arranging reef base units in at least two rows increases the seabed coverage and overall strength of the reef base zone, enhancing its impact on the marine ecosystem. The minimum spacing of two reef base units between adjacent reef base zones allows for flexible adjustment based on seabed area and ecological restoration needs. This spacing design ensures that the reef base zones do not interfere with each other while creating reasonable seawater circulation channels, facilitating seawater circulation and providing sufficient oxygen and nutrients for reef-building and reef-protecting organisms on the growth platform and corals in the coral planting troughs, thus promoting a healthy cycle in the marine ecosystem.
[0010] Furthermore, the reef base unit is cylindrical, and the coral planting troughs are distributed circumferentially along the top edge of the reef base unit. The cylindrical reef base unit has a simple structure and is easy to manufacture. At the same time, it experiences less resistance during seawater flow, which can reduce the impact of seawater on the reef base unit and improve its stability.
[0011] Furthermore, the reef base unit is made by integrally pressing a mixture of slag powder, fly ash, alkali activator, glass fiber, and fine sand. This allows for waste recycling and reuse, and the reef base unit is integrally molded, avoiding modular splicing, reducing production costs, and improving structural stability.
[0012] Furthermore, the reef base unit is equipped with support strips located at the bottom of the growth platform. These support strips effectively support the growth platform, preventing it from deforming or being damaged due to the weight of the coral growth or the impact of seawater. This ensures the structural stability and service life of the growth platform, thereby providing a stable environment for coral growth.
[0013] Compared with the existing technology, the beneficial effects of this utility model are as follows: it integrates coral planting, fish habitat and small organism attachment functions. The coral planting trough provides a dedicated growth space for corals, and the hollow part inside forms a safe habitat for fish, enriching marine biodiversity and solving the problem of the single function of existing reef bases. Geogrids have a two-dimensional mesh structure, which facilitates seagrass attachment. Their pore structure can simulate the pore environment between seagrass plants, adapt to the size of fish eggs, improve the attachment rate of seagrass and fish eggs, and further reduce the loss of seabed sediment.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0020] Please see Figures 1-3 A multifunctional marine ecological reef base includes a reef base unit 1, a seabed 10, and a geogrid 2. The top of the reef base unit 1 is provided with a growth platform 3, and the edges of the growth platform 3 are distributed with coral planting troughs 4. The interior of the reef base unit 1 is provided with a fish habitat area 5. The top of the reef base unit 1 is also provided with hollow holes 6 that connect to the fish habitat area 5 inside it. Several reef base units 1 are embedded in the seabed 10 and arranged closely to form a reef base belt. Multiple reef base belts are arranged at intervals on the seabed 10. The geogrid 2 is laid on the seabed 10 between two adjacent reef base belts and has mesh openings. Specifically, the reef base unit 1 can be gripped by a dedicated hydraulic robotic arm and then rotated and pressed into the seabed 10. By rotating the reef base unit 1, its bottom is cut into the seabed 10, thereby fixing the reef base unit 1 to the seabed 10. The reef base unit 1 embedded in the seabed 10 plays a role in stabilizing the seabed and protecting the slope, reducing sediment loss, blocking ocean currents from eroding the seabed, and strengthening the restoration and protection of islands and slopes. The geogrid 2 can be laid on the seabed 10 by anchoring, nailing, or other fixing methods. The geogrid 2 has a two-dimensional mesh structure, which facilitates seagrass attachment. Its pore structure can simulate the pore environment between seagrass, adapt to the size of fish eggs, improve the attachment rate of seagrass and fish eggs, and further reduce seabed sediment loss. The coral planting trough 4 on the reef base unit 1 is used to fix the transplanted corals, and the growth platform 3 is set up as a transplantation area for reef-building and reef-protecting organisms such as coral algae, calcified algae, and giant clams, as well as a coral growth area. In addition, several small pits can be set on the surface of the reef base unit 1, especially in the coral planting trough 4, to simulate the surface structure of seabed rocks in the natural environment, so as to provide attachment points for coral algae, calcified algae, giant clams, etc., promote the rapid reproduction of algae and the formation of algal mats, and provide a stable ecological environment for coral growth.
[0021] In this embodiment, the reef base unit 1 has a hollow section extending to its bottom. The lower section of the reef base unit 1 is embedded in the seabed 10, and the interior of the reef base unit 1 forms a fish habitat 5 in the hollow section above the seabed 10. This fully utilizes the internal space of the reef base unit 1, providing ample habitat for fish. At the same time, the embedding of the lower section of the reef base unit 1 into the seabed 10 further enhances the stability of the reef base unit 1 on the seabed, preventing displacement of the reef base unit 1 due to seawater flow.
[0022] In this embodiment, the bottom edge of the reef base unit 1 is provided with a support leg 7 that matches the shape of the coral planting trough 4. During transportation, the reef base unit 1 can be stacked by the corresponding fitting of the support leg 7 with the coral planting trough 4, which facilitates transportation and improves the stacking stability during transportation. During installation, the support leg 7 is inserted into the seabed 10 to enhance the stability of its installation structure and prevent the reef base unit 1 from shifting under the scouring of ocean currents.
[0023] In this embodiment, the reef base units 1 of each reef base zone are arranged in at least two closely spaced rows, with a minimum spacing of two reef base units 1 width between adjacent reef base zones. Arranging the reef base units 1 in at least two rows to form a reef base zone increases the coverage area and overall strength of the reef base zone on the seabed, enhancing its impact on the marine ecological environment. The minimum spacing of two reef base units 1 width between adjacent reef base zones allows for flexible adjustment based on seabed area and ecological restoration needs. This spacing design ensures that the reef base zones do not interfere with each other while also creating a reasonable seawater circulation channel, facilitating seawater circulation and providing sufficient oxygen and nutrients for the reef-building and reef-protecting organisms on the growth platform 3 and the corals in the coral planting trough 4, thus promoting a healthy cycle of the marine ecosystem.
[0024] In this embodiment, the reef base unit 1 is cylindrical, and the coral planting troughs 4 are distributed circumferentially along the top edge of the reef base unit 1. The cylindrical reef base unit 1 has a simple structure and is easy to manufacture. At the same time, it experiences less resistance during seawater flow, which can reduce the impact of seawater on the reef base unit 1 and improve its stability.
[0025] In this embodiment, the reef base unit 1 is mainly made of a mixture of materials such as slag powder, fly ash, alkali activator, glass fiber, and fine sand, which are pressed into shape by mold to realize waste recycling and reuse. The reef base unit 1 is integrally formed, avoiding modular splicing, reducing production costs and improving structural stability. In addition, the above materials have good resistance to chloride ions and seawater corrosion, which can effectively extend the service life of the reef base unit 1 and reduce the negative impact of the reef base itself on the marine ecology.
[0026] In this embodiment, the reef base unit 1 is provided with a support strip 8 located at the bottom of the growth platform 3. The support strip 8 can effectively support the growth platform 3, preventing the growth platform 3 from deforming or being damaged due to the weight of coral growth or the impact of seawater, ensuring the structural stability and service life of the growth platform 3, and thus providing a stable environment for coral growth.
[0027] The working principle of this utility model is as follows: First, with the help of auxiliary tools such as hydraulic robotic arms, the reef base unit 1 is driven into the seabed. The closely arranged reef base units 1 form a reef base zone. There is at least a gap of two reef base units 1 width between adjacent reef base zones to form a suitable seawater circulation channel, which facilitates the circulation of seawater between the reef base zones and promotes the exchange of materials between different areas. The lower end of the reef base unit 1 is embedded in the seabed. The reef base zone formed by the closely arranged reef base units 1 plays the role of preventing waves and preventing sand and soil erosion. Geogrid 2 is laid between two adjacent reef base zones to further prevent silt loss and improve the attachment rate of seaweed and fish eggs.
[0028] The beneficial effects achieved by this utility model are as follows: Integrating coral planting, fish habitat, and small organism attachment functions, the coral planting trough 4 provides a dedicated growth space for corals, while the hollowed-out part inside forms a safe habitat for fish, enriching marine biodiversity and solving the problem of the single function of existing reef bases. Geogrid 2 is a two-dimensional mesh structure, which facilitates seagrass attachment. Its pore structure can simulate the pore environment between seagrass, adapt to the size of fish eggs, improve the attachment rate of seagrass and fish eggs, and further reduce the loss of seabed sediment.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
