Description

Technical Field

[0001] This invention belongs to the technical field of reef structures for the breeding and conservation of octopuses, specifically relating to an octopus spawning reef structure and its manufacturing method. Background Technology

[0002] Cephalopods are an important marine economic species, especially octopuses, which are the main economic species in shallow waters. In recent years, due to the deterioration of the nearshore ecological environment and overfishing, the habitats and spawning grounds of nearshore cephalopods, including octopuses, have been greatly reduced, directly affecting the reproduction and survival of cephalopods and leading to a gradual decline in their resources. Summary of the Invention

[0003] This invention provides an octopus spawning reef, designed to provide habitat and spawning grounds for octopuses in coastal or nearshore areas, thereby restoring their resource levels.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A reef for octopus spawning is provided, comprising:

[0006] The reef body has an internal cavity. The side walls of the reef body have water passage holes and several cave entrances. Each cave entrance is inclined and the outer side of the cave entrance is the lower end.

[0007] Several nest bodies correspond one-to-one with the cave entrance; each nest body is located inside the cavity of the reef body; the opening of each nest body is connected to the inner wall of the reef body through a connecting component, and the opening of the nest body communicates with the cave entrance.

[0008] The nest body and the connecting component are rotatably coupled so that the nest body tilts downward under its own weight.

[0009] In one possible implementation, the connecting component includes a spherical shell having opposing openings; one end of the spherical shell is located within the opening of the nest body, and the diameter portion is also located within the opening of the nest body; the other end of the spherical shell is connected to the inner wall of the reef body.

[0010] The spherical shell has a flange, and the spherical shell is connected to the reef body by a flange; the inner wall of the nest body has a spherical surface that matches the spherical shell.

[0011] In one possible implementation, the inner wall of the nest body has a limiting member at the cave entrance, the limiting member being disposed below the cave entrance, the limiting member being used to contact the outer side of the nest body to limit the lowest position of the nest body.

[0012] In one possible implementation, the reef body is connected to a downward-sloping pipe on the outer wall of the cave entrance, the free end of which has a downward-facing oblique opening.

[0013] This invention provides a cephalopod spawning reef. Compared with existing technologies, the nest body is connected to the reef body via a connecting component. Under its own weight, the nest body can rotate downwards relative to the connecting component, allowing it to be in a downward-tilted state. Therefore, it provides a relatively concealed and stable protective environment for the cephalopod eggs, reducing the risk of the eggs being washed away by water currents or preyed upon by other organisms. By providing water passage holes on the reef body, seawater exchange between the inside and outside of the reef body can be promoted. This reduces the impact of water currents on the reef body and facilitates the survival of marine organisms within the reef body's cavities. By setting the cave entrance at an angle, the angle between the nest body and the cave entrance restricts the turning of other fish swimming into the cave entrance, thus reducing the likelihood of other fish swimming directly into the nest body and protecting the eggs inside.

[0014] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0015] A method for constructing an octopus spawning reef is provided, comprising the following steps:

[0016] Both the outer and inner templates have a first through hole corresponding to the water passage hole of the reef body and a second through hole aligned with the cave entrance.

[0017] Insert the infill plate into the outer formwork through the first through hole, and insert several infill columns into the outer formwork through the second through hole. Then tie the reinforcing cage inside the outer formwork.

[0018] After the reinforcement cage is tied, the inner formwork is hoisted into the outer formwork; the position of the inner formwork can be restricted by the insertion and cooperation of the filling plate with the first through hole on the inner formwork, and the hoisting equipment can be removed at this time.

[0019] Several filling columns are inserted into the inner template through the second through hole of the inner template;

[0020] Pour concrete into the space between the inner and outer formwork. After the concrete has solidified to the preset strength, remove the infill board, infill column, inner formwork, and outer formwork.

[0021] Install the nest body in the corresponding position on the inner periphery of the reef body.

[0022] In one possible implementation, each outer side wall of the outer template is provided with a connecting frame, and the connecting frame is connected to all the filling columns on the corresponding connecting side of the outer template; when the filling column is inserted into the second through hole, the connecting frame enables several filling columns to be inserted into the corresponding second through hole at the same time.

[0023] In one possible implementation, when the reinforcing cage is tied into the interior of the outer formwork, both the infill plate and the infill column are in the first insertion position, which will not affect the hoisting of the inner formwork.

[0024] In one possible implementation, a stop block is hinged to the filler plate, and the filler plate is in a first insertion position when the stop block faces the side wall of the outer template and is in contact with the outer template.

[0025] A connecting plate is fixedly provided on the connecting frame, and bolts are provided on the connecting plate. The filling plate has threaded holes aligned with the bolts. After the connecting plate and the filling plate are connected by bolts, the filling column is in the first insertion position, and the positions of the filling column and the filling plate are relatively fixed.

[0026] In one possible implementation, after removing the filling plate, filling column, inner template, and outer template, before installing the nest body on the reef body, the surface of the reef body is formed with micron-level grooves and protrusions by sandblasting, mechanical carving, or chemical treatment. This not only satisfies the egg-laying needs of octopuses but also promotes the attachment of microbial communities, algae, and shellfish, ensuring the feeding of octopuses.

[0027] The beneficial effects of the method for constructing octopus spawning reefs provided in this application are the same as those of spawning reefs, and will not be repeated here. Attached Figure Description

[0039] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0040] Please refer to the following: Figures 1 to 10The present invention will now describe a reef for octopus spawning. The octopus spawning reef includes a reef body 1 and a nest body 2. The reef body 1 has an internal cavity. The sidewalls of the reef body 1 have water passage holes 11 and several cave entrances 12, each cave entrance 12 being inclined, with its outer side being the lower end. Several nest bodies 2 correspond one-to-one with each cave entrance 12. Each nest body 2 is located within the cavity of the reef body 1. The opening of each nest body 2 is connected to the inner sidewall of the reef body 1 via a connecting component 3, and the opening of the nest body 2 communicates with the cave entrance 12. The nest body 2 and the connecting component 3 are rotatably coupled, causing the nest body 2 to tilt downwards under its own weight.

[0041] This invention provides a cephalopod spawning reef. Compared with the prior art, the nest body 2 is connected to the reef body 1 by a connecting component 3. Under its own weight, the nest body 2 can rotate downward relative to the connecting component 3, so that the nest body 2 can be in a downward tilted state. Therefore, it can provide a relatively hidden and stable protective environment for the cephalopod eggs, reducing the risk of the eggs being washed away by the water flow or preyed upon by other organisms. By setting water passage holes 11 on the reef body 1, the exchange of seawater inside and outside the reef body 1 can be promoted. On the one hand, it can reduce the impact of the water flow on the reef body 1, and on the other hand, it can facilitate the survival of marine organisms in the cavity of the reef body 1. By setting the cave entrance 12 in an inclined manner, since there is an angle between the nest body 2 and the cave entrance 12, when other fish swim into the cave entrance 12, it will restrict the turning of other fish, thus reducing the situation where other fish swim directly into the nest body 2, which can protect the eggs inside the nest.

[0042] It should be noted that the reef body 1 is placed in a shallow sea area with stable currents. After the reef body 1 is stably placed on the seabed, the nest body 2 is positioned at an angle downwards and remains relatively stable. The nest body 2 is connected to the reef body 1 via a connecting component 3, and the nest body 2 and the connecting component 3 rotate in coordination. In the event of an emergency, if the nest body 2 is subjected to an external force that could cause it to rotate, the nest body 2 can reduce the impact of the external force on the connecting component 3 by adjusting its angle, thereby improving the stability between the connecting component 3 and the reef body 1. Compared to the method of directly fixing the nest body 2 to the reef body 1, the above-mentioned arrangement of this application can improve the stability of the nest body 2 and enhance its ability to cope with emergencies. Here, stability refers to the ability of the nest body 2 to be connected to the reef body 1, reducing the possibility of the nest body 2 separating from the reef body 1. The top of the reef body 1 is open, facilitating the entry of operators into the reef body 1 to install the nest body 2 on the inner side of the reef body 1.

[0043] In some embodiments, such as Figures 1 to 10 As shown, the connecting component 3 includes a spherical shell 31 with openings that are arranged opposite each other; one end of the spherical shell 31 is located inside the opening of the nest body 2, and the diameter portion is also located inside the opening of the nest body 2; the other end of the spherical shell 31 is connected to the inner wall of the reef body 1; wherein, the spherical shell 31 has a flange 33, and the spherical shell 31 is connected to the reef body by a flange; the inner wall of the nest body 2 has a spherical surface that mates with the spherical shell 31.

[0044] It should be noted that by placing one end of the spherical shell 31 inside the opening of the nest body 2 and connecting it to the opening end of the nest body 2 through two semi-circular retaining rings 32, the portion of the spherical shell 31 that exceeds its diameter is located inside the nest body 2. Therefore, when the nest body 2 and the spherical shell 31 rotate, the separation of the nest body 2 from the spherical shell 31 can be avoided. The inner wall of the semi-circular retaining ring 32 has a curved surface that fits against the spherical surface. The semi-circular retaining ring 32 can be fixed to the opening end of the nest body 2 by bolts or by welding.

[0045] For example, a flange 33 is fixedly provided at the other end of the spherical shell 31. The spherical shell 31 is fixed to the inner wall of the reef body 1 by the flange 33. By fixing the flange 33 on the spherical shell 31 and providing a connection hole on the reef body 1, an expansion sleeve is placed in the connection hole. The expansion sleeve has internal threads. When the bolt and the expansion sleeve are threaded together, the expansion sleeve will expand outwards, thereby fixing the expansion sleeve in the connection hole. Through the cooperation of the bolt and the expansion sleeve, the flange 33 can be fixed to the reef body 1, thereby connecting the nest body 2 to the reef body 1. Both the bolt and the expansion sleeve are made of corrosion-resistant material. By rotating the nest body 2 and the spherical shell 31 together, the operator can rotate the nest body 2 to an unobstructed position when installing the spherical shell 31, making it convenient for the operator to install the spherical shell 31 onto the reef body 1.

[0046] For example, the nest body 2 on the seabed can be inspected regularly by detection equipment. If the nest body 2 is damaged, divers can be arranged to replace the nest body 2.

[0047] In some embodiments, such as Figures 1 to 10 As shown, the inner wall of the nest body 2 has a limiting component 4 at the cave entrance 12. The limiting component 4 is located below the cave entrance 12 and is used to contact the outer side of the nest body 2 to limit the lowest position of the nest body 2.

[0048] For example, the limiting component 4 is located on the outside of the spherical shell 31 and at the bottom of the spherical shell 31; when the opening end of the nest body 2 contacts the limiting component 4, the limiting component 4 can limit the nest body 2, reducing the possibility of the opening of the spherical shell 31 unscrewing out of the nest body 2.

[0049] In some embodiments, such as Figures 1 to 10 As shown, the reef body 1 is connected to a downward-sloping pipe 5 on the outer wall of the cave entrance 12, and the free end of the pipe 5 has a downward-facing oblique opening.

[0050] It should be noted that by setting a downward-sloping pipe 5 on the outside of the cave entrance 12, with the pipe 5 parallel to the cave entrance 12, other fish can be confined within the pipe 5 and the cave entrance 12, limiting their turning and thus reducing the chance of other fish entering the nest body 2. To a certain extent, this can improve the concealment of the cave entrance 12 and protect the eggs inside the nest body 2.

[0051] Based on the same inventive concept, this application also provides a method for making an octopus spawning reef, comprising the following steps:

[0052] Both the outer template 6 and the inner template 7 have a first through hole corresponding to the water passage hole 11 of the reef body 1 and a second through hole aligned with the cave entrance 12. The filling plate 8 is inserted into the outer template 6 through the first through hole, and several filling columns 9 are inserted into the outer template 6 through the second through hole. Then, a steel cage is tied inside the outer template 6. After the steel cage is tied, the inner template 7 is hoisted into the outer template 6. The position of the inner template 7 can be restricted by the insertion and cooperation of the filling plate 8 with the first through hole on the inner template 7. At this time, the hoisting equipment can be removed. Several filling columns 9 are inserted into the inner template 7 through the second through hole. Concrete is poured into the space between the inner template 7 and the outer template 6. After the concrete has solidified to the preset strength, the filling plate 8, filling columns 9, inner template 7 and outer template 6 are removed. The nest body 2 is installed at the corresponding position on the inner peripheral wall of the reef body 1.

[0053] It should be noted that when tying the reinforcing cage inside the outer formwork 6, the reinforcing bars need to avoid the infill plate 8 and the infill column 9; by setting up the reinforcing cage, the strength of the reef can be improved; during the concrete mixing process, carbon fiber materials can be added to the concrete to improve the strength of the reef.

[0054] In some embodiments, such as Figures 1 to 10 As shown, each outer side wall of the outer template 6 is provided with a connecting frame 91, and the connecting frame 91 is connected to all the filling columns 9 on the corresponding connecting side of the outer template; when the filling column 9 is inserted into the second through hole, the connecting frame 91 enables several filling columns 9 to be inserted into the corresponding second through hole at the same time.

[0055] It should be noted that connecting all the filling columns 9 on the same side through the connecting frame 91 facilitates the management of the filling columns 9 and reduces the occurrence of missing filling columns 9; on the other hand, it facilitates the overall installation and removal of the filling columns 9 on the same side.

[0056] In some embodiments, such as Figures 1 to 10 As shown, when the reinforcing cage is tied into the interior of the outer formwork 6, both the filling plate 8 and the filling column 9 are in the first insertion position, which will not affect the hoisting of the inner formwork 7. A stop block 81 is hinged on the filling plate 8. When the stop block 81 faces the side wall of the outer formwork 6 and is in contact with the outer formwork 6, the filling plate 8 is in the first insertion position. A connecting plate 92 is fixedly provided on the connecting frame 91. The connecting plate 92 is provided with bolts, and the filling plate 8 has threaded holes aligned with the bolts. After the connecting plate 92 and the filling plate 8 are connected by bolts, the filling column 9 is in the first insertion position, and the positions of the filling column 9 and the filling plate 8 are relatively fixed.

[0057] It should be noted that there are several stop blocks 81, which are set on the top and both sides of the filler plate 8. The stop blocks 81 are hinged to the filler plate 8, and the filler plate 8 has clearance grooves 82 for avoiding the stop blocks 81. The stop blocks 81 can rotate within the clearance grooves 82. When the filler plate 8 is in the first insertion position, the filler post 9 is inserted into the second through hole of the outer template 6. When the bolt on the connecting plate 92 is aligned with the threaded hole on the filler plate 8, the bolt is connected to the filler plate 8. At this time, the positions of the filler post 9 and the filler plate 8 are relatively fixed, and the insertion direction of the filler post 9 and the filler plate 8 is at an angle, thus achieving the locking function.

[0058] In some embodiments, such as Figures 1 to 10 As shown, after removing the filling plate 8, filling column 9, inner template 7 and outer template 6, before installing the nest body 2 on the reef body 1, the surface of the reef body 1 is formed with micron-level grooves and protrusions by sandblasting, mechanical carving or chemical treatment. This not only satisfies the egg-laying of octopuses, but also promotes the attachment of microbial communities, algae and shellfish, ensuring the feeding of octopuses.

[0059] It should be noted that setting micron-level grooves and protrusions on the surface of the reef body 1 can improve the surface roughness of the reef body 1, with a surface roughness of 20-100 μm, to simulate the texture of natural rock reefs; through the above setting, it is easy for algae to attach to the surface of the reef body 1 and form a stable biofilm or algal cover layer.

[0060] For example, the reef body 1 can be made of high-strength composite materials, such as carbon fiber composite materials or glass fiber composite materials combined with ceramics. This can ensure good corrosion resistance and mechanical strength of the material, as well as high specific surface area and porosity, which is conducive to the attachment of microbial communities, enhances the ecological value of the reef body 1, and is suitable for long-term exposure in the marine environment.

[0061] For example, a suitable deployment area is selected, such as a shallow sea area with stable currents (v < 0.5 m / s) and suitable water depth (6-30 m), or the optimal aquatic environment for habitat and spawning is selected according to the habits of cephalopods; the reef body 1 is placed on the seabed to ensure the stability of the reef body 1 and avoid displacement of the reef body 1 due to water flow or other factors.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
