Description

Technical Field

[0001] This utility model relates to the field of marine ecological restoration technology, and in particular to a combined artificial reef. Background Technology

[0002] Artificial reefs are man-made structures erected in the sea to improve the marine ecological environment, create favorable habitats for marine life, and provide places for fish and other marine organisms to reproduce, grow, forage, and shelter from predators, thereby achieving the goals of protection, propagation, and increased fish catches. The construction of artificial reefs has been widely carried out both domestically and internationally for the restoration of nearshore marine habitats and fishing grounds, with good results achieved.

[0003] Most existing artificial reefs are cubic frames with limited surface area, which cannot provide sufficient attachment space for marine plants and animals such as shellfish and algae, nor can they provide adequate shelter. Utility Model Content

[0004] The purpose of this invention is to provide a modular artificial reef that can provide a large surface area for marine plants and animals to attach to, and has a good protective function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a combined artificial reef, including a single reef unit, the single reef unit including three connecting shafts, the straight directions of the three shafts intersecting at the same point and not on the same plane, and also including multiple reef surfaces, each of the reef surfaces being connected to the connecting shafts respectively, forming a shelter space between the multiple reef surfaces, and each of the reef surfaces having a first through hole.

[0006] Preferably, the connecting shaft is tubular, and a second through hole is provided on each of its surfaces.

[0007] Preferably, the three connecting shafts of each artificial reef unit are perpendicular to each other, the reef surface is in the shape of an equilateral triangle, each artificial reef unit has eight reef surfaces, and the combined shape of the eight reef surfaces is a regular octahedron.

[0008] Preferably, the artificial reef unit includes a cubic connecting part, each side of which is provided with a sleeve for connecting a connecting shaft. Each connecting shaft consists of two segments, and each segment of the connecting shaft is connected to two sleeves in a straight line on the connecting part.

[0009] Preferably, the connecting part is a regular hexahedron with a hollow interior, and there are 6 sleeves, which are respectively connected to each face of the connecting part.

[0010] Preferably, the diameter of the three connecting shafts of each artificial reef unit decreases sequentially, so that the three connecting shafts can be fitted together.

[0011] Preferably, the system also includes linear connectors, which connect the plurality of artificial reef units sequentially through a connecting shaft of each artificial reef unit.

[0012] Preferably, when multiple artificial reef units are placed, two adjacent artificial reef units are connected to each other, with the smaller connecting shaft of one artificial reef unit inserted into the larger connecting shaft of another artificial reef unit.

[0013] Preferably, the connecting shaft and the reef surface are prefabricated components.

[0014] Preferably, the surface of the reef body is provided with a convex shape.

[0015] Preferably, the reef body is detachably connected to the connecting shaft.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. By adopting a prefabricated component assembly method, it breaks away from the traditional one-piece molded artificial reef model, realizes the equipmentization of artificial reefs, and makes them easier to produce, handle, transport, install and deploy;

[0018] 2. Connecting shafts of different pipe diameters can be nested together, and reef bodies can be stacked, further reducing transportation space and lowering transportation costs;

[0019] 3. Convex shapes are arranged on the prefabricated panels of each reef to increase the surface area of ​​the reef, which is conducive to the proliferation and growth of marine plants and animals;

[0020] 4. Water permeability: The unique octahedral structure design allows water to flow smoothly through each first through hole of the reef. The size of the first through hole can be designed according to the water flow of the area where it is placed. This not only brings abundant nutrients to marine life, but also improves the water quality environment around the reef, which is conducive to the attachment, growth and survival of organisms. The permeable structure allows seawater to flow smoothly inside and around the reef, which is conducive to the exchange and circulation of nutrients, improves the water quality environment around the reef and is more conducive to the survival of marine life.

[0021] 5. Structural stability: The three connecting shafts are grounded, which makes the artificial reefs very stable in seawater. They can be placed individually or in a string. Multiple artificial reefs can be strung together with steel chains to form a large whole. They can also be stacked, with strong stability and not easily dispersed by water currents. This solves the problem of poor water flow caused by stacking artificial reefs in existing technologies, creating a good habitat and breeding environment for marine life.

[0022] 6. Depending on the seabed substrate in the area where the artificial reef is placed, connecting shafts of different lengths can be designed to prevent the artificial reef from sinking or tilting excessively, and to avoid the bottom surface of the reef from contacting the seabed. This will increase the flow of seawater and the movement and habitat of organisms. The bottom surface of the octahedral artificial reef does not contact the seabed, which can reduce the impact on benthic organisms when the artificial reef is placed.

[0023] 7. It can provide a large surface area for marine plants and animals to attach to, and has good water permeability and does not damage the bottom ecosystem. It can also connect multiple artificial reefs together to prevent individual reefs from being washed away by ocean currents. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0035] Example: The smallest unit usable in this modular artificial reef is a single reef unit, and each reef unit includes, as follows: Figure 1 The three connecting shafts 1 and connecting part 3 shown are all tubular, with several second through holes 11 on their surface. The straight lines of the three connecting shafts 1 intersect at the same point in space, and each pair is perpendicular to the others. Their positional relationship corresponds to the x-axis, y-axis, and z-axis in a spatial coordinate system, and they are internally connected. When the artificial reef is placed underwater, the ends of any three connecting shafts 1 are in contact with the bottom, giving the artificial reef a high degree of stability. Each connecting shaft 1 consists of two sections, and the diameter of the three connecting shafts 1 gradually decreases, allowing them to be nested together.

[0036] In one embodiment of this technical solution, the connecting part 3 is a six-way pipe with six sleeves. The two ends of each connecting shaft 1 are respectively connected to two sleeves located in the same straight direction.

[0037] like Figure 2 As shown, in another embodiment of this technical solution, the connecting part 3 is a regular hexahedron with a hollow interior. Each of the six faces is connected to a sleeve, and the six sleeves are in a connected state inside the connecting part 3. The two ends of each connecting shaft 1 are respectively connected to two sleeves located in the same straight direction.

[0038] like Figure 3 As shown, each individual reef also includes eight equilateral triangular reef surfaces 2, each of which is connected to three connecting shafts 1. The eight reef surfaces 2 are combined to form a regular octahedron. Each reef surface 2 has a first through hole 21.

[0039] The first through-hole 21 and the second through-hole 11 allow for smooth water flow, increasing water mobility within the main body of the reef, facilitating the entry and exit of organisms, and helping to reduce the weight of the individual reef units. The space enclosed by the connecting shaft 1 and the reef surface 2 provides shelter for plants and animals. The tubular connecting shaft 1 and the plate-like reef surface 2 provide a large surface area for plants and animals to attach to. When the individual reef unit is placed, the three connecting shafts 1 support it on the seabed, ensuring stable placement. When the seabed is soft, the design of longer connecting shafts 1 allows for space to allow the reef unit to sink, preventing the bottom reef surface 2 from sinking underground and ensuring its continued usability.

[0040] like Figure 4 As shown, each reef body 2 is also provided with convex shapes 5 on its surface. In this embodiment, hemispherical protrusions are used to further increase the surface area of ​​the reef body 2, which is conducive to the growth of plants and animals.

[0041] Furthermore, the reef body 2, connecting shaft 1, and connecting part 3 are all prefabricated components. The reef body 2, connecting shaft 1, and connecting part 3 are detachably connected. The method of using this artificial reef unit is as follows: the reef body 2, connecting shaft 1, and six-way pipe 3 are manufactured in the factory, transported to the sinking site or port, and then quickly assembled. During transportation, the three connecting shafts 1 with decreasing diameters are nested together, and the reef bodies 2 are stacked, greatly reducing transportation space and lowering transportation costs.

[0042] Artificial reef units can be placed individually or in strings.

[0043] When placed in a string, multiple individual artificial reefs are connected in series by linear connectors 4; in this embodiment, steel chains are used. This stringing arrangement not only facilitates creating various shapes but also prevents the individual reefs from being washed away by water currents and causing damage.

[0044] like Figure 5 As shown, one method of placing them in a string involves arranging multiple individual artificial reefs in a circular pattern.

[0045] like Figure 6 As shown, one method of placing them in a string involves arranging multiple individual reefs in a spiral pattern.

[0046] like Figure 7 As shown, one placement method is to naturally stack multiple artificial reef units. When using this method, multiple artificial reef units can be connected in series using steel chains, or not.

[0047] like Figure 8 As shown, one method of placement without steel chains involves placing multiple artificial reef units close together in sequence, with adjacent artificial reef units connected to each other, and the smaller connecting shaft 1 of one artificial reef unit being inserted into the larger connecting shaft 1 of another artificial reef unit.
