[0002] Artificial reefs are structures artificially set up in the sea. Their purpose is to improve the ecological environment of the sea area, create a good environment for marine life to live, and provide fish with a place to reproduce, grow, forage and shelter from enemies, so as to achieve the purpose of protection, proliferation and increase of fish catch.

[0042] 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 invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0043] As global fishery resources are increasingly depleted, protecting and restoring marine ecosystems has become an important research topic. Artificial reefs have received widespread attention as an effective means of marine ecological restoration. Artificial reefs use artificial materials to simulate the structure and function of natural reefs, providing fish and other marine organisms with a place to live, forage, reproduce, and avoid enemies. By deploying artificial reefs in specific sea areas, the local marine ecological environment can be improved, biodiversity can be increased, and the recovery and sustainable development of fishery resources can be promoted.

[0044] The materials and structural design of artificial reefs directly affect their ecological benefits and durability. Traditional artificial reefs are mostly made of concrete, steel, etc. Although these materials are excellent in strength and durability, they are insufficient in environmental protection and ecological adaptability. In recent years, with the increase of environmental awareness, more and more researchers have begun to explore the use of natural materials and degradable materials to make artificial reefs to reduce the negative impact on the marine environment.

[0045] At the same time, existing artificial fish reefs are generally composed of multiple main bodies 1 spliced ​​together, but the splicing components between the multiple main bodies 1 are usually exposed outside the main body 1. When the artificial fish reefs are placed in the ocean, the water flow will impact the splicing components exposed outside the main body 1, affecting the stability and durability of the splicing connection; and the impact of ocean currents on artificial fish reefs is unknown. Placing artificial fish reefs in locations with strong water flow may cause the reef structure to be unable to withstand the impact of water flow, causing the reef to be damaged or even disintegrated in the ocean, affecting the service life of the artificial fish reefs.

[0046] In order to solve the above problems, an embodiment of the present invention proposes an artificial fish reef, which meets environmental protection requirements, is simple to assemble and has a stable structure, can be put into use in the ocean for a long time, and can effectively promote the recovery and development of the marine ecosystem.

[0047] like Figure 1 As shown, the artificial fish reef of this embodiment includes a plurality of main bodies 1 , a plurality of first assemblies 3 and a plurality of second assemblies 4 .

[0048] It should be noted that the number of the main body 1, the first assembly 3 and the second assembly 4 are set according to actual conditions. The number of assemblies required for splicing different numbers of main bodies 1 is different, and the specific number of the main body 1, the first assembly 3 and the second assembly 4 is not limited here.

[0049] In this embodiment, the main body 1 is made of appropriate giant dragon bamboo, and the appearance of the main body 1 presents a cylindrical structure of the giant dragon bamboo.

[0050] It should be noted that when making the main body 1, giant dragon bamboo without obvious cracks, damage or decay should be used as the raw material for making the main body 1; the bamboo material should be dried to reduce the moisture content to prevent structural problems caused by water absorption expansion or shrinkage during later installation; and the outer surface of the giant dragon bamboo should be polished to make the outer surface of the main body 1 smooth and without sharp protrusions to avoid causing harm to fish or other marine life.

[0051] The selection of giant dragon bamboo should take into account its strength, diameter and natural corrosion resistance. In this embodiment, the diameter of each giant dragon bamboo needs to be greater than 25 cm to meet the structural requirements; the height of the fish reef is five times the diameter of the giant dragon bamboo to ensure that the final fish reef is approximately a cube; the wall thickness should be greater than 1 / 6 of its diameter to ensure that drilling does not affect the overall strength of the giant dragon bamboo.

[0052] In addition, the inner wall of the giant dragon bamboo is rough. The inner wall of the giant dragon bamboo naturally has a certain degree of roughness and irregularity. This natural roughness can promote the smearing of algae and other marine organisms to a certain extent. By utilizing this natural characteristic, these natural rough structures can be retained and utilized as much as possible during the selection and processing of bamboo, thereby reducing the cost and complexity of additional processing.

[0053] like Figure 2 As shown, in this embodiment, each main body 1 is provided with a fish nest hole 2, and a first through hole 5 penetrating the main body 1 and a second through hole (not marked in the figure) penetrating the main body 1 are provided at the same outer circle height of each main body 1.

[0054] It should be noted that the fish nest holes 2 can be distributed at any position of the main body 1 to provide a passage for fish to enter, live and forage. The size and position of the fish nest holes 2 are designed according to the needs of different fish to ensure that various fish can find a suitable living space in the artificial reef.

[0055] Before the production and design of the main body 1, it is possible to determine in advance what fish exist in the marine environment where the artificial fish reef is placed, and design the artificial fish reef to a size suitable for the survival of the target fish in that marine environment. The aperture of the fish nest hole 2 is set to be at least larger than half of the average maximum body width of the target fish, and usually 75% of the maximum body width of the fish is taken as the aperture of the fish nest hole 2.

[0056] Furthermore, an internal passage connected to the fish nest hole 2 may be provided in the main body 1, so that the target fish can reach into the main body 1, providing a safe living space for the fish.

[0057] In addition, a first through hole 5 and a second through hole are provided at the same height on the outer wall of each main body 1. The first through hole 5 penetrates the main body 1 so that the first assembly 3 can penetrate the main body 1 through the first through hole 5; and the second through hole also penetrates the main body 1 so that the second assembly 4 can penetrate the main body 1 through the second through hole, thereby splicing multiple main bodies 1.

[0058] It should be noted that the first through hole 5 and the second through hole are evenly distributed on the main body 1 by drilling, and the distance between the first through hole 5 and the second through hole on each main body 1 is fixed. The drilling process should avoid excessive impact on the structural strength of the bamboo. A drill bit of appropriate size can be used for drilling. The drill bit should be slightly smaller than the hole diameter to reduce the risk of cracks; and a low-speed high-torque drill should be used to avoid cracking of the bamboo caused by drilling too quickly. After drilling, the edge of the hole needs to be polished to remove any sharp edges to prevent harm to fish.

[0059] In this embodiment, multiple main bodies 1 are arranged horizontally and vertically in advance, and during the arrangement process, the first through holes 5 of each main body 1 in the same row are aligned to form a channel for inserting the first assembly 3; the second channels of each main body 1 in the same column of the arranged multiple main bodies 1 are aligned to form a channel for inserting the second assembly 4.

[0060] The sizes of the first through hole 5 and the second through hole must be much larger than the diameters of the first assembly 3 and the second assembly 4, so as to provide sufficient space for the first assembly 3 and the second assembly 4 to be spliced ​​in the main body 1. After splicing, there is a certain gap between the first through hole 5 and the second through hole, and the ecological filler 6 can be filled in the gap, such as Figure 2 As shown, the first assembly part 3 and the second assembly part 4 are prevented from moving in the through hole, ensuring that the first assembly part 3 and the second assembly part 4 are stably engaged inside the main body 1 .

[0061] like Figure 3 As shown, in this embodiment, a plurality of shaft segments 31 are provided on the first assembly 3, and the shaft segments 31 can be longitudinally opened from a plurality of designated positions of the first assembly 3 by turning or other means to form a plurality of recessed positions, each recessed position forming a shaft segment 31 of the first assembly 3, so that the diameter of each shaft segment 31 is smaller than the diameter of the first assembly 3; and the distance between each shaft segment 31 of the first assembly 3 is the same, so as to facilitate the subsequent engagement and splicing with the second assembly 4.

[0062] like Figure 4As shown, the second assembly 4 is provided with a plurality of slots 41, and the distribution of the plurality of slots 41 on the second assembly 4 is the same as the arrangement of the shaft segments 31 on the first assembly 3. At the same time, the shape of the slots 41 matches the shape of the shaft segments 31, so that the shaft segments 31 can be precisely engaged with the slots 41 to achieve the effect of mortise and tenon fixing.

[0063] Combination Figure 1 As shown, during the assembly of the artificial reef, the main bodies 1 are arranged horizontally and vertically, the first through holes 5 between the main bodies 1 arranged horizontally are connected, and the first assembly 3 passes through the first through hole 5 of each main body 1 arranged horizontally; and the second through holes between the main bodies 1 arranged vertically are connected, and the second assembly 4 passes through the second through hole of each main body 1 arranged vertically; at the same time, the shaft section 31 of the first assembly 3 and the slot 41 of the second assembly 4 located in the same main body 1 are spliced ​​by using the internal space of the first through hole 5 and the second through hole, as shown in FIG. Figure 5 As shown, Figure 5 A in the middle indicates the meshing and splicing position of the first assembly part 3 and the second assembly part 4. In the cross-sectional angle of the main body 1, the first assembly part 3 and the second assembly part 4 in the main body 1 mesh with each other and form a cross-shaped structure.

[0064] After the first assembly parts 3 and the second assembly parts 4 in each main body 1 are spliced ​​together, the mortise and tenon gaps in the main body 1 are filled with ecological fillers 6, which may be sand, concrete blocks or other environmentally friendly materials, so that the manufactured artificial fish reef can sink to the seabed under the action of gravity and increase the stability of the overall structure.

[0065] Each main body 1 is spliced ​​together by the first assembly 3 and the second assembly 4 to form an artificial fish reef with a three-dimensional geometric structure. The connection between the first assembly 3 and the second assembly 4 is hidden in the main body 1, and the gap in the connection in the main body 1 is filled with the ecological filler 6 to reduce the impact of water flow on the connection, which can extend the service life of the fish reef; the artificial fish reef is put into the ocean, and the fish in the ocean can survive in the artificial fish reef, which effectively promotes the recovery and development of the marine ecosystem.

[0066] In order to further improve the feasibility of placing artificial reefs in the ocean, the environmental load can be dynamically analyzed and its impact on artificial reefs can be simulated, so as to optimize the arrangement and placement of artificial reefs to ensure that the artificial reefs can achieve maximum ecological benefits.

[0067] Specifically, Figure 6 As shown, another embodiment of the present invention provides a method for installing and testing the artificial reef as described above, which specifically includes the following steps:

[0068] Step S1: Obtain environmental load parameters of the artificial fish reefs placed in the marine environment, and simulate the resistance of the artificial fish reefs in the marine environment according to the environmental load parameters.

[0069] The artificial fish reefs made of giant dragon bamboo are placed into the marine environment, and the placement location of the artificial fish reefs is recorded. The environmental loads such as waves and tides at the placement location are measured by Doppler current meters, wave buoys, wave sensors and other equipment and instruments, and the environmental load parameters that change over time are recorded in real time.

[0070] The bending moment caused by environmental loads is crucial to the structural integrity of artificial reefs. Therefore, the loads of the marine environment need to be quantified. Specifically, the expression of environmental loads is:

[0071] F(t)=F0·cos(ωt+φ);

[0072] Among them, F(t) represents a time-dependent dynamic load, F0 is the maximum load amplitude, ω is the angular frequency of the wave, φ is the phase difference, and t is time. Data such as the maximum load amplitude, angular frequency, and phase difference can all be measured by equipment and instruments.

[0073] The bending moment of the artificial reef over time is calculated based on the environmental load. The expression of the bending moment is:

[0074] M(t) = F(t)·L;

[0075] Among them, M(t) represents the bending moment that changes with time, F(t) represents a time-dependent dynamic load, and L represents the distance from the giant dragon bamboo fixing point to the force point.

[0076] The distance between the fixing point of the giant dragon bamboo and the stress point can be determined by simulating the stress conditions of the artificial reef under the current environmental load through simulation software, and conducting a mechanical analysis on the artificial reef, so as to determine the distance between the specified fixing point on the artificial reef and the specified stress point.

[0077] In this embodiment, through a large number of simulation tests, it is found that the distance between the fixing point of the giant dragon bamboo and the force-bearing point is close to half the length of the giant dragon bamboo. Therefore, in this embodiment, L is directly set to half the length of the bamboo.

[0078] It should be noted that the technology of simulating stress conditions using simulation software has been disclosed in the prior art and will not be described again here.

[0079] Furthermore, the characteristics of artificial reefs are analyzed to obtain the bamboo characteristics of artificial reefs, which include bamboo length, bamboo diameter, etc. The bending stress is calculated based on the bending moment and bamboo characteristics, and the expression of bending stress is:

[0080]

[0081] Among them, σ(t) represents the bending stress that changes with time t; y is the farthest distance from the point where the stress is calculated to the neutral axis of the cross section, which is usually taken as half of the radius of the bamboo; I is the moment of inertia of the section, which is used to measure the ability of the section to resist bending; D is the diameter of the bamboo.

[0082] After calculating the bending moments of each bamboo in the artificial reef at different positions, a bending moment diagram can be drawn to show the magnitude and direction of the bending moment at any point on each bamboo. Find the location of the maximum bending moment along the entire length of the bamboo, and then determine the maximum bending stress of the bamboo.

[0083] Step S2: determining the angle between the load direction and the axis of the bamboo in the artificial reef according to the angle of placement of the artificial reef, and determining the shear strength of the artificial reef according to the angle and environmental load parameters.

[0084] When artificial fish reefs are placed in the marine environment, their placement angles are different, and the bamboo axis of each giant dragon bamboo in the artificial fish reef will be different from the load direction of ocean waves. Therefore, simulation software is used to simulate the angle between the axis of each bamboo and the current load direction when the artificial fish reef is placed in the marine environment at a fixed time point or under a stable environmental condition. Tools such as compasses or goniometers can even be used to manually measure the angle between the load direction and the bamboo column axis at a fixed time point or under a stable environmental condition during the installation and layout process.

[0085] Subsequently, the dynamic shear force of the artificial reef is calculated according to the angle and the environmental load, the shear stress is calculated according to the dynamic shear force and the mortise and tenon contact area of ​​the artificial reef, and the shear strength of the artificial reef is determined according to the dynamic shear force and the shear stress.

[0086] Among them, the environmental load is calculated based on the environmental load parameters, and its expression formula is:

[0087] F(t)=F0·cos(ωt+φ);

[0088] Among them, F(t) represents a time-dependent dynamic load, F0 is the maximum load amplitude, ω is the angular frequency of the wave, φ is the phase difference, and t is time.

[0089] The calculation formula of dynamic shear force is:

[0090] V(t) = F(t)·cos(θ);

[0091]

[0092] Where V(t) represents the time-dependent shear force, θ represents the angle between the load and the axis of the bamboo column, τ(t) is the time-dependent shear stress, and A jointIt is the contact area of ​​the mortise and tenon connection structure between the first assembly part 3 and the second assembly part 4.

[0093] Step S3: When the resistance capacity does not meet the first test condition and / or the shear strength does not meet the second test condition, a prompt instruction is generated, where the prompt instruction is used to remind the user to switch the placement position of the artificial reef and / or to remind the user to update the arrangement structure of the artificial reef.

[0094] The specific method for judging whether the resistance meets the first test condition is as follows:

[0095] The calculated bending stress is compared with the allowable bending stress of the material, where the allowable bending stress is usually obtained by dividing the yield strength or ultimate strength of the material by a safety factor. If the calculated bending stress is less than or equal to the allowable bending stress, the cross-section of the artificial reef giant dragon bamboo is considered to be sufficient to resist the stress caused by the bending moment.

[0096] If the bending moment stress is greater than the allowable bending stress, it is considered that the artificial reef with the current structure cannot resist the stress caused by the bending moment. At this time, a prompt instruction is generated to remind the user to switch the placement of the artificial reef to change the environmental load faced by the artificial reef and / or update the arrangement structure of the artificial reef to optimize the impact of the environmental load on the artificial reef.

[0097] The specific method for judging whether the shear strength meets the second test condition is:

[0098] Determine whether the shear stress is less than the allowable shear stress of the material. The allowable shear stress is usually determined by dividing the limiting shear stress obtained through material testing by a safety factor. When the calculated shear stress is less than or equal to the allowable shear stress, it means that the material is stable and will not be damaged. If the calculated shear stress is greater than the allowable shear stress, it means that the material is unstable and the artificial reef will be sheared off at the shear surface.

[0099] During the process of judging the resistance capacity and shear strength, trigger reminder rules can be set, that is, the trigger reminder rules include immediately executing a reminder operation when the resistance capacity does not meet the first test condition, or immediately executing a reminder operation when the shear strength does not meet the second test condition, or executing the reminder operation only when both the resistance capacity does not meet the first test condition and the shear strength does not meet the second test condition, so as to improve the flexibility of the reminder.

[0100] During the installation and placement stage of the artificial reef, the rationality of the artificial reef of the current structure in the current placement position is evaluated in real time through the dynamic analysis of the resistance capacity and shear strength. If the resistance capacity and / or shear strength are not up to standard, the placement position of the artificial reef is adjusted to change the environmental load, and / or the arrangement layout of each main body 1 in the artificial reef is changed. The load distribution and the stress and deformation of the structure under different installation positions and layouts are recorded through experiments, and finally the optimal installation position and structural layout are determined to minimize the stress and deformation of the structure under various environmental loads, thereby determining the optimal installation position and the optimal structural layout.

[0101] This embodiment ensures the stability and safety of the reef in a dynamic environment by regularly monitoring the structural response of the reef. Incorporating dynamic environmental load analysis into the design and testing phase of the reef can significantly improve the predictability and reliability of the reef structure. This not only contributes to the long-term stability of the reef, but also ensures the maximization of its ecological function.

[0102] The embodiment of the present invention manufactures a giant dragon bamboo fish reef by means of the mortise and tenon joints of the first assembly 3 and the second assembly 4, forming a stable and environmentally friendly artificial fish reef structure, providing an innovative and environmentally friendly solution, and effectively solving the problems of environmental pollution, structural instability, and low ecological benefits existing in traditional artificial fish reefs; giant dragon bamboo is used as the main material, which is low in cost and easy to obtain, reducing the manufacturing and maintenance costs of artificial fish reefs, and the corrosion-resistant giant dragon bamboo and stable mortise and tenon structure extend the service life of the fish reef and reduce the frequency of replacement and maintenance. The present invention significantly improves the environmental performance, structural stability, and ecological benefits of artificial fish reefs through scientific technical solutions and innovative designs, has good social, economic, and technical benefits, and provides an effective solution for marine ecological protection and the sustainable development of fishery resources.
