Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of artificial reefs, in particular to a modular anchor chain type artificial reef. BACKGROUND

[0002] In recent years, marine ranching has been rapidly developing worldwide as an important way of sustainable utilization of marine resources. Artificial reefs, as a key component of marine ranching, simulate the environmental characteristics of natural reefs to provide abundant habitats and breeding grounds for marine organisms. Reasonable reef structure can significantly affect the flow field distribution in the surrounding sea area, accelerate the circulation of nutrients, and promote the construction and stability of biological communities. At the same time, the attached organisms on the surface of the reef can also participate in the material cycle and energy flow of the marine ecosystem, playing a positive role in improving biodiversity and restoring and growing fishery resources.

[0003] However, in the face of changing marine environments and increasing human activities, traditional artificial reefs have certain limitations in structural design. Although they can improve the ecological environment of the seabed and promote biodiversity to some extent, their functionality still needs to be improved in terms of specific biological groups such as parent fish spawning and juvenile fish protection.

[0004] The structural design of artificial reefs has a significant impact on factors such as water flow and nutrient distribution. Complex structural design can provide diverse hiding spaces and ecological niches for different species of organisms, attracting them to inhabit; and reasonable layout can optimize water flow conditions, promote material exchange and biological activity. The design of artificial reefs needs to consider many factors, not only to meet ecological needs, but also to consider natural environmental factors such as the hydrodynamic characteristics of the specific sea area and the geological conditions of the seabed, as well as social and economic factors such as transportation capacity and cost-effectiveness. SUMMARY

[0005] To solve the problems in the prior art, the present application provides a modular anchor chain type artificial reef, which is configured with a combination structure of anchor modules and chain modules. The anchor modules mainly serve to fix the overall structure and provide spawning attachment bases for reef-dependent fish to improve the survival rate and hatching rate of fish eggs; the chain modules mainly serve to extend the overall structure and increase the structural complexity, while providing nurseries or shelters for reef-dependent fish or cephalopods. The two modules or the components within the modules have an assembly type connection structure, and the functions of the two modules are complementary to meet the needs of target biological species in the target sea area throughout their life history.

[0006] The technical solution of the present application is as follows:

[0007] In a first aspect of the invention, a modular anchor-chain artificial reef is provided, comprising an anchor module and a chain module, wherein the main body of the anchor module is an anchor-type artificial reef, and the main body of the chain module is a chain-type artificial reef; the anchor-type artificial reef and the chain-type artificial reef are connected by a ball-and-socket structure; the anchor-type artificial reef includes an anchor shank, an anchor foot, and an anchor claw, the anchor foot and anchor claw being respectively disposed at the head and tail ends of the anchor shank, and the anchor shank is covered with a hatching trough, which serves as an attachment substrate for reef-loving fish to lay their eggs; the chain-type artificial reef includes multiple fish chambers connected by a ball-and-socket structure, the fish chambers serving as a habitat and shelter space for reef-loving fish.

[0008] In some embodiments of the present invention, the ball joint structure includes a connecting rod, a ball head, and a ball seat. The two ends of the connecting rod are connected to the ball seat. The ball head rotates 90° within the ball seat. A threaded rod is fixedly connected to the ball head. The ball head is installed on the threaded hole of the anchor shank or fish chamber through the threaded rod.

[0009] In some embodiments of the present invention, the connecting rod includes a buffer sleeve and a buffer rod, wherein a limit spring and a buffer spring are provided inside the buffer sleeve, and one end of the buffer rod extends into the buffer sleeve, and the buffer rod can perform piston movement inside the buffer sleeve.

[0010] In some embodiments of the present invention, the ball seat includes a ball cover, a ball seat base, and a ball seat slot. The ball cover and the ball seat base are connected by an arrow-shaped protrusion and a slot. A pair of symmetrical ball seat slots are provided on both sides of the slot. A retaining spring extends into the ball seat slot to connect and fix the ball cover and the ball seat base.

[0011] In some embodiments of the present invention, the hatching tank has an inverted truncated groove structure, and multiple water circulation holes are opened on the tank wall away from the anchor shank. The opening direction of the water circulation holes is parallel to the central axis of the anchor shank. The tank opening has a baffle that slopes inward toward the inside of the tank opening.

[0012] In some embodiments of the present invention, multiple hatching tanks are arranged around the outer periphery of the anchor shank, and multiple layers are arranged along the central axis of the anchor shank, with the hatching tanks of adjacent layers being distributed in a cross pattern.

[0013] In some embodiments of the present invention, the fish chamber is in the shape of a symmetrical fan-shaped column, and the sides of the fish chamber are a pair of symmetrical inner arch surfaces and a pair of symmetrical outer arch surfaces. An opening is provided on the inner arch surface, and symmetrical ear plates inclined inward are provided on both sides of the opening.

[0014] In some embodiments of the present invention, symmetrical ear plate slots are provided on the outer arch surface, and the symmetrical ear plate slots and symmetrical ear plates are matched, so that multiple fish chambers can be connected by the cooperation of the symmetrical ear plate slots and symmetrical ear plates.

[0015] In some embodiments of the present invention, the interior of the fish chamber is divided into two fish compartments by a partition, and each fish compartment has two openings.

[0016] In some embodiments of the present invention, the anchor head of the anchor foot is fixed to the first end of the anchor shank by an elliptical rod, and the anchor claw is fixed to the tail end of the anchor shank by a hemispherical central base.

[0017] One or more technical solutions of the present invention have the following beneficial effects:

[0018] (1) In view of the fact that the current artificial reefs are simple in structure and single in function, that is, they cannot meet the functional structure required by the target species at each stage of their life history, the anchor reef with spawning protection function and the chain reef with juvenile protection function can be combined into a unit reef through modular combination. This can form a habitat with complete functions with a modular anchor chain reef as the center.

[0019] (2) The anchor-type module is based on an anchor-type artificial reef and is equipped with anchor claws and anchor feet in four directions. It utilizes the principle of anchor embedding itself into the seabed to fix the artificial reef, similar to an anchor, to enhance its resistance to slippage and capsizing in high-velocity waters. The hatching tank structure wrapped around the anchor shank provides an attachment substrate for reef-loving fish such as rockfish to spawn. The hatching tank structure also protects the fish eggs from the risk of being washed away by the water flow and predation, increasing the survival rate of the fish eggs and creating a suitable spawning ground habitat for reef-loving fish in this sea area.

[0020] (3) The chain module is based on a chain reef. The fish chamber with ear plates can prevent mud and sand from entering the fish chamber, increase the shelter of the fish chamber and increase the defense against juvenile fish and cephalopod predators. At the same time, the connecting rod enables the chain module to complete a deformation process similar to chain movement and provides buffering. While improving the spatial structure complexity and space utilization, it provides more space for juvenile fish and cephalopods to forage, stay and avoid predators. It can also form a complex structure of interpenetrating stacks and nests through the chain structure in complex geological environments. Its overall structure is more stable than that of a general single reef.

[0021] (4) It adopts a modular structure with an assemblable connection structure between two modules or between components within a module. The anchor shank and fish chamber can be assembled with the threaded structure at the bottom of the ball head support rod. The ball seat adopts a separate slot structure. All components are modularly mass-produced on land, transported to the deployment site, and then assembled into an anchor chain-type overall structure. It sinks through a hinge, which does not need to consider the specific direction of the current, making it convenient for deployment and facilitating the embedding of the reef into the bottom.

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

[0034] Example 1

[0035] Most artificial reefs currently used adopt simple, regular structures, including square, frame, cylindrical, and hemispherical artificial reefs. These reefs are combined to form a surrounding flow field or functional zone suitable for the target species. However, with the development of marine ranching, research has found that the construction of artificial reefs is strictly subject to the influence of natural environmental factors. These include problems such as slippage, overturning, and capsizing due to the impact of water flow, burial and subsidence due to silt, and increased predation rate of juvenile fish. In other words, simple, regular reef structures have problems such as limited functionality and low space utilization.

[0036] In recent years, experts have proposed the construction of marine ranches covering the entire life cycle of fish. This means that the marine ranch construction area should have artificial structures that can fully provide spawning grounds, nursery grounds, feeding grounds, and other structures adapted to the target species. While considering cost-effectiveness, the functionality of artificial reefs should be increased to provide different habitats based on artificial reefs and other artificial structures for the target species at different growth stages.

[0037] To address the aforementioned problems, a typical embodiment of the present invention proposes a modular anchor chain artificial reef, such as... Figures 1-10 As shown, the artificial reef includes an anchor module 1 and a chain module 2. The main body of the anchor module 1 is an anchor-type artificial reef, and the main body of the chain module 2 is a chain-type artificial reef. The anchor-type artificial reef and the chain-type artificial reef are connected by a ball-and-socket structure. The anchor-type artificial reef includes an anchor shank 3, an anchor foot 5, and an anchor claw 4. The anchor foot 5 and the anchor claw 4 are respectively located at the head and tail ends of the anchor shank 3. The anchor shank 3 is covered with a hatching trough 6, which serves as an attachment base for reef-loving fish to spawn. The chain-type artificial reef includes multiple fish chambers 7 connected by a ball-and-socket structure. The fish chambers 7 serve as a habitat and shelter space for reef-loving fish.

[0038] The anchor-type modules provide spawning attachment substrates for reef-loving fish to improve the survival and hatching rates of fish eggs. The chain-type modules provide nurseries or shelters for reef-loving fish or cephalopods. The functions of the anchor-type modules and the chain-type modules complement each other to meet the multifunctional needs of target species for spawning, raising young, and avoiding predators within a single reef unit.

[0039] like Figure 1 and Figure 2 As shown, the modular anchor chain artificial reef includes an anchor module 1 and a chain module 2. The main structure of the anchor module 1 is an anchor artificial reef, and the main structure of the chain module 2 is a chain artificial reef. The connection between the anchor module 1 and the chain module 2, as well as the connection between the fish chambers 7 in the chain module 2, are all made through a simple ball joint structure.

[0040] like Figure 3As shown, the two modules are structurally decomposed. The anchor-type artificial reef mainly consists of an anchor shank 3, anchor claws 4, and anchor feet 5. The four anchor claws 4 and anchor feet 5 are respectively connected to the tail end of the anchor shank 3, forming a symmetrical anchor-type main structure. The anchor shank 3 is wrapped with a hatching tank 6. The fish chamber 7 is the main structure of the chain-type artificial reef. The ball joint structure is the connection structure between modules and between fish chambers, and it also has the functions of buffering and providing axial rotational movement. The simple ball joint structure includes a connecting rod, a ball head, and a ball seat. The two ends of the connecting rod are connected to the ball seat. The ball head rotates 90° in the ball seat. A threaded rod is fixedly connected to the ball head. The ball head is installed on the threaded hole of the anchor shank 3 or the fish chamber 7 through the threaded rod. The ball head 8 and the limiting ball seat can provide the functions of extension and folding movement. The top of the ball head 8 is three-quarters spherical. The lower part of the three-quarters spherical structure is curved inward and connected to the support rod to ensure stability. The lower part of the support rod also has a threaded structure, which can be transported separately from the anchor reef and the fish chamber 7.

[0041] like Figure 4 As shown, the anchor foot 5 is fixed to the head end of the anchor shank 3 by an elliptical rod, and the anchor claw 4 is fixed to the tail end of the anchor shank by a hemispherical central base 12. Specifically, the four anchor claws 4 have their heads evenly distributed on the hemispherical central base 12 at the bottom of the anchor shank 3 by U-shaped rods, and the shackle 11 can move around the center of the hole at the top of the anchor shank. The four anchor claws on the anchor shank 3 are distributed at a 90° angle, while the ball head connected to the anchor foot on the anchor shank 3 at the bottom of the shackle 11 is distributed at a 60° angle.

[0042] The head of anchor claw 4 has a concave conical structure on the inner side near the center of the anchor shank, and a barb structure on the outer side away from the center of the anchor shank. When the reef sinks, due to the viscosity of the water and the reef's own weight or the action of a crane, this structure can more quickly embed the reef into the seabed and complete its fixation. The head of anchor foot 5 is diamond-shaped with warped structures at its four corners. This provides support for the reef when it reaches the seabed, reducing the chance of sinking and minimizing the burial of sediment carried by the surrounding water flow. When the reef sinks and embeds itself in the sedimentary seabed, the combination of the structures of anchor claw 4 and anchor foot 5 ensures that the reef presents a certain lateral angle to the current on the seabed, preventing it from slipping and capsizing.

[0043] like Figure 5 As shown, the hatching tank 6 has an inverted truncated pyramidal groove structure. Multiple water circulation holes are opened on the tank wall away from the anchor shank 3, and the opening direction of the water circulation holes is parallel to the central axis of the anchor shank. The tank opening has a baffle that slopes inward and is perpendicular to the central axis of the anchor shank. Multiple hatching tanks 6 are arranged around the outer periphery of the anchor shank, and multiple layers are arranged along the central axis of the anchor shank, with the hatching tanks in adjacent layers intersecting.

[0044] In one specific embodiment of this example, the groove wall away from the anchor shank has six water circulation holes with opening directions parallel to the central axis of the anchor shank. The groove opening has baffles that slope inwards. The centroids overlap and are perpendicular to the central axis of the anchor shank. Six sets are arranged in a circle around the center of the anchor shank. There is a seamless groove structure between two adjacent composite blocks in the cross section. The hatching trough structure of two adjacent circles along the central axis of the anchor shank is crisscrossed, with a total of ten circles. The hatching trough can provide an attachment substrate for spawning and hatching of reef-loving fish such as the large-scaled six-lined rockfish.

[0045] After mating, the fertilized eggs produced by the rockfish in the large-scaled fish are not initially sticky. The inclined plate at the opening of the hatching tank serves to collect the fertilized eggs to the bottom of the tank. Uncollected fertilized eggs will enter the next layer of hatching tanks along the grooves between adjacent hatching tanks. This allows the fertilized eggs to adhere to each other in the hatching tank, forming egg masses and attaching to the bottom of the tank, thus reducing the loss rate of fertilized eggs. At the same time, the structure of the hatching tank can create a slow-flow zone around the reef. The water circulation holes on the tank wall ensure sufficient water circulation inside the hatching tank without losing fish eggs, providing sufficient oxygen and protection for the fish eggs, thereby improving the hatching rate of the fry.

[0046] like Figure 6 As shown, the fish chamber 7 is a symmetrical fan-shaped column with its top and bottom surfaces forming symmetrical fan surfaces and connected to a pair of ball heads 8. The sides of the fish chamber have a pair of symmetrical inner arch surfaces and a pair of symmetrical outer arch surfaces. Openings are provided on the inner arch surfaces for fish to enter and exit. At the same time, the arch structure can raise the fish chamber to reduce the intrusion of mud and sand.

[0047] The fish chamber is divided into two compartments by a partition, each compartment having two openings. Symmetrical ear plates 13, inclined inwards on both sides of each opening, increase the compartment's concealment and enhance its defense against predators. Symmetrical ear plate slots 14 are provided on the outer arch surface to increase water exchange between the inside and outside of the fish chamber 7, perpendicular to the opening direction. The symmetrical ear plate slots and symmetrical ear plates match, allowing multiple fish chambers to be interlocked via the engagement of the symmetrical ear plate slots and symmetrical ear plates. This enables the fish chambers to be joined and fixed together with the inner arch facing the outer arch, facilitating transportation.

[0048] like Figure 7 As shown, the connecting rod includes a buffer sleeve 9 and a buffer rod 10. The buffer sleeve 9 is a hollow cylinder with a circular opening on its top surface. One end of the buffer rod extends into the buffer sleeve, and the buffer rod can perform piston-like movements inside the buffer sleeve. The buffer rod 10 is a cylindrical rod, and the top of both the inner and outer parts of the buffer rod 10 has a circular buffer plate.

[0049] The buffer sleeve 9 is equipped with a limit spring and a buffer spring. The limit spring is arranged around the buffer rod 10, and the buffer spring is connected to the bottom of the buffer sleeve 9. To ensure that the same working length can be achieved under the same free length, the wire diameter of the limit spring is half that of the buffer spring, but the number of turns of the limit spring is twice that of the buffer spring. The limit spring can provide buffering for the connecting rod during the stretching process and control the termination length to reduce the risk of breakage. The buffer spring can provide buffering for the connecting rod during the impact process to reduce the risk of collision and breakage between the connecting structures.

[0050] like Figure 8 As shown, the ball seat includes a ball seat cover 15, a ball seat base 17, and a ball seat bayonet 16. The ball seat is assembled in a separate manner to facilitate the connection between modules and components. The ball seat has a 90° one-way slot from the top to the side wall, which constrains the ball head 8 within the 90° range of movement in the slot direction, so that the fish chambers 7 can perform a 180° relative rotational movement.

[0051] Furthermore, the ball seat cover 15 and the ball seat base 17 are connected by an arrow-shaped protrusion and a slot. A pair of symmetrical ball seat slots 16 are provided on both sides of the slot. A retaining spring extends into the ball seat slot to connect and fix the ball seat cover 15 and the ball seat base 17. At the same time, concrete adhesive is used to reinforce the joint to ensure structural stability while reducing the risk of slippage.

[0052] In this embodiment, as Figures 1-8 As shown, a set of dimensional parameters for anchor-type and chain-type modules are given as examples. The length of the anchor shank 3 with the outer covering of the hatching tank 6 is L; the length of the upper anchor shank without the outer covering of the hatching tank 6 is 0.2L; the height of the hatching tank is 0.1L; the width of the tank opening is 0.1L; the slope of the outer wall relative to the tank bottom is 60°; and the inclination of the tank opening baffle relative to the tank opening is 30°. The distance from the geometric center of the anchor foot 5 to the central axis of the anchor shank 3 is 0.5L; the major axis length of the anchor foot head is 0.2L; and the minor axis length is 0.1L. The length of the anchor claw 4 near the center of the anchor shank is 0.5L, and the bending angle with the end away from the center of the anchor shank is 120°. The length of the anchor claw 4 away from the central axis of the anchor shank 3 is 0.2L, and the angle with the outer edge of the barb of the anchor claw head is 30°. The height of the columnar structure of fish chamber 7 is 0.12L, therefore the major axis of the symmetrical fan-shaped surface of fish chamber 7 is 0.09L, and the arc of the inner and outer arches of fish chamber 7 is 60°. The diameter of the ball head 8 is 0.03L, the inner diameter of the ball seat is 0.033L, and the outer diameter is 0.045L. The length of the buffer sleeve 10 is 0.075L.

[0053] Before deploying the modular chain artificial reef, the separate components related to the anchor module 1 and chain module 2 can be mass-produced on land. During transportation, the fish chamber 7 can be assembled to reduce the transport volume of the components, and then the components, including the connection of the ball head 8 in the ball seat, can be assembled at the deployment site.

[0054] Compared to conventional modular reefs, this modular anchor chain artificial reef possesses greater adaptability in sea areas with complex seabed structures and can form a stable overall structure, thereby creating a stable artificial habitat, such as... Figures 9-10 The artificial reefs and reef clusters they form can provide more habitat and shelter for juvenile reef-loving fish and cephalopods, improve the survival rate of juvenile reef-loving fish and cephalopods, and restore fishery resources in the target sea area. The modular anchor chain artificial reef can achieve seabed fixation in sea areas with greater water flow without human fixation, effectively increasing its service life.

[0055] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
