Description

Technical Field

[0001] The invention relates to the technical field of marine ecological ranches, and in particular to an ecological self-descending stereoscopic aquaculture forming coral reef and a reef forming method thereof which has the advantages of simple structure, high stability, low cost, long service life and convenient installation. Background Art

[0002] Marine ranching is a fishing model based on the principle of marine ecosystem. In specific sea areas, artificial reefs, proliferation and release are used to build or repair places needed for marine organisms to reproduce, produce, feed or avoid enemies, increase and conserve fishery resources, improve the marine ecological environment, and achieve sustainable utilization of fishery resources. Artificial reef construction is the main measure of marine ranching, and it is recognized by the world as an effective measure to improve the marine ecological environment, repair and increase damaged fishery resources.

[0003] At present, existing artificial reefs are generally placed directly on the seabed via mesh boxes, which requires the mesh boxes to be very heavy to overcome the effects of waves and seabed buoyancy. Therefore, the installation process is very cumbersome, with high installation and production costs. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and to provide an ecological self-descending three-dimensional aquaculture forming coral reef and a reef forming method thereof which has a simple structure, high stability, low cost, long service life and convenient installation.

[0005] The technical solution adopted by the present invention to solve its technical problem is: An ecological self-descending three-dimensional aquaculture forming coral reef is provided with a reef-forming shell, which is made of a material resistant to seawater corrosion. The reef-forming shell is in the shape of a cone, and the top of the cone-shaped reef-forming shell is open and hinged with a cover plate. The cover plate, the side plate of the reef-forming shell, and the bottom plate of the reef-forming shell are respectively configured as grid plates. At least two plug rods are fixedly connected below the bottom plate of the reef-forming shell. The lower ends of the edges of the cone-shaped reef-forming shell are respectively connected to reef-forming tubes. The upper ends of the reef-forming tubes are connected to the lower ends of the edges of the reef-forming shell. The lower ends of the reef-forming tubes are connected to a pile body via a connecting rope. The pile body is inserted into the seabed. Net-shaped attachment ropes are respectively arranged on the inner walls of the reef-forming shell. Shellfish seedlings that provide weight and climbing functions are placed inside the reef-forming shell, and coral seedlings are placed on the outer wall of the reef shell.

[0006] The inner wall of the reef-forming tube of the present invention is provided with a mesh-shaped attachment rope, shellfish seedlings providing weight and climbing functions are placed inside the reef-forming tube, and the attachment ropes are spirally wound on the outer wall of the reef-forming tube, and seaweed seedlings are attached to the attachment ropes.

[0007] The pile body of the present invention is installed on the seabed outside the reef shell. After the ground screw is connected to the reef shell through the reef tube, the reef tube is expanded outward. Adjacent reef tubes are respectively connected with attachment ropes from top to bottom, and seaweed seedlings are attached to the attachment ropes.

[0008] The attachment rope described in the present invention comprises an inner core and an outer fixing rope, wherein the inner core is a cotton-like inner core, and the outer fixing rope is spirally wound on the outer wall of the cotton-like inner core. The outer fixing rope is made of fiber material, and the pitch of the spirally wound outer fixing rope is 0.3-0.5mm. The diameter of the cotton-like inner core is 0.5-1.0cm. The cotton-like inner core provides adhesion to corals and seaweed seedlings, and the outer fixing rope made of fiber material increases the toughness of the entire attachment rope.

The spiral blades are wound around the outer wall of the conical tube, a flange is connected to the outer wall of the upper end of the conical tube, and a plurality of through holes are distributed on the tube wall of the conical tube. The ground screw is inserted into the seabed through a tightening machine connected to the flange. The inside of the ground screw is filled with sea sand, and seaweed is planted in the sea sand. The roots of the seaweed pass through the sea sand filled in the conical tube of the ground screw and then drill straight into the sea sand outside the ground screw through the through holes, thereby increasing the holding force between the ground screw and the sea sand on the seabed.

[0011] The outer wall of the reef shell, the outer wall of the reef tube and the attachment rope between the reef tubes of the present invention are connected with stinging needles, the length of the stinging needles is 10-20 cm, the attachment ropes are protected by the stinging needles, and the grown corals, algae and water tanks can also be prevented from being eaten by marine organisms.

[0012] The shellfish seedlings providing weight function described in the present invention are oysters, and the shellfish seedlings providing climbing function are mussels. The oysters are preferably rock oysters. Ammonium salt or phosphate particles are arranged on the cotton-like inner core of the attachment rope to increase the growth of algae and aquatic plants.

[0013] The shellfish seedling growth climbing frame is arranged in the reef-forming shell of the present invention. The shellfish seedling growth climbing frame includes a bottom support rod and a climbing rod. At least two bottom support rods are provided. The bottom support rods are connected to each other, and the climbing rods are vertically connected to the connected bottom support rods.

The reef-forming shell 1 is in the shape of a cone, and the top of the cone-shaped reef-forming shell 1 is open and hinged with a cover plate 2. The cover plate 2, the side plate of the reef-forming shell 1, and the bottom plate of the reef-forming shell 1 are respectively set as grid plates. At least two plug rods 15 are fixedly connected below the bottom plate of the reef-forming shell 1. The lower ends of the edges of the cone-shaped reef-forming shell 1 are respectively connected to reef-forming tubes 3, the upper ends of the reef-forming tubes 3 are connected to the lower ends of the edges of the reef-forming shell 1, and the lower ends of the reef-forming tubes 3 are connected to the pile body 4 through connecting ropes. The pile body 4 is inserted into the seabed, and mesh attachment ropes are arranged on the inner walls of the reef-forming shell 1. Shellfish seedlings that provide weight and climbing functions are placed inside the reef-forming shell 1, and coral seedlings are placed on the outer wall of the reef-forming shell 1.

[0022] Furthermore, a mesh attachment rope is arranged on the inner wall of the reef-forming tube 3, shellfish seedlings are placed inside the reef-forming tube 3 to provide weight and climbing functions, and an attachment rope 5 is spirally wound on the outer wall of the reef-forming tube 3, and seaweed seedlings are attached to the attachment rope 5.

[0023] Furthermore, the pile body 4 is installed on the seabed outside the reef shell 1. After the ground screw is connected to the reef shell 1 through the reef tube 3, the reef tube 3 is expanded outward, and the adjacent reef tubes 3 are connected with attachment ropes 5 from top to bottom, and the attachment ropes 5 are attached to the seaweed seedlings.

[0024] Furthermore, the attachment rope 5 includes an inner core 6 and an outer fixing rope 7, wherein the inner core 6 is a cotton-like inner core 6, and the outer fixing rope 7 is spirally wound on the outer wall of the cotton-like inner core 6. The outer fixing rope 7 is made of fiber material, and the pitch of the spirally wound outer fixing rope 7 is 0.3-0.5 mm. The diameter of the cotton-like inner core 6 is 0.5-1.0 cm. The cotton-like inner core 6 provides adhesion to corals and seaweed seedlings, and the outer fixing rope 7 made of fiber material increases the toughness of the entire attachment rope 5.

[0025] Furthermore, the upper end of the reef-forming tube 3 is connected to the upper hook ring 8, and the lower end of the edge of the reef-forming shell 1 is connected to the lower hook ring 9. The reef-forming tube 3 is universally connected to the reef-forming shell 1 through the sleeve connection of the upper hook ring 8 and the lower hook ring 9.

[0026] Furthermore, the pile body 4 is configured as a ground screw, which includes a conical tube 10 and a spiral blade 11. The outer wall of the conical tube 10 is wound with the spiral blade 11. A flange 12 is connected to the outer wall of the upper end of the conical tube 10. A plurality of through holes 13 are distributed on the tube wall of the conical tube 10. The ground screw is inserted into the seabed through a tightening machine connected to the flange 12. The inside of the ground screw is filled with sea sand, and seaweed is planted in the sea sand. The roots of the seaweed pass through the sea sand filled in the conical tube 10 of the ground screw and then drill straight into the sea sand outside the ground screw through the through holes 13, thereby increasing the holding force between the ground screw and the sea sand on the seabed.

[0027] Furthermore, the outer wall of the reef-forming tube 3 and the attachment rope 5 between the reef-forming tubes 3 are connected with stinging needles 14, the length of the stinging needles 14 is 10-20 cm, and the attachment rope 5 is protected by the stinging needles 14.

The bottom support rods 16 are at least two, and the bottom support rods 16 are connected to each other. The climbing rods 17 are vertically connected to the connected bottom support rods 16. Even if the reef-forming shell is corroded and broken, the shellfish can still tightly cling to the climbing rods and grow, making the reef structure after reef formation more stable.

[0030] A method for forming a coral reef by an ecological self-descending stereoscopic aquaculture method, the characteristic use of which is as follows: (1) Reef making: preparing ecological self-descending three-dimensional aquaculture coral reefs; (2) Reef installation: installing the ecological self-descending three-dimensional aquaculture shaped coral reef prepared in step (1) on the seabed; (3) Inoculation of shellfish, algae and corals: a. Inoculating shellfish: after setting up the reef in step (2), artificially go into the sea, open the lid, and arrange two kinds of shellfish seedlings that provide weight and attachment functions respectively. The shellfish seedlings that provide weight function are oysters, and the shellfish seedlings that provide attachment function are mussels. The shellfish seedlings are replenished every 3-4 months; b. Inoculating algae: In step (2), the attachment rope of the ecological self-descending stereoscopic aquaculture forming coral reef is wrapped with kelp, seaweed and other attached algae; c. Inoculating corals: In step (2), inoculate corals on the outer side of the reef shell of the ecological self-descending stereoscopic aquaculture-formed coral reef; (4) Management period: Check regularly at sea. If the reef shell is blown crooked by the waves, straighten it manually. Observe the penetration of the rod into the soil and assist with insertion manually. At the same time, regularly clean the algae attached to the corals on the surface of the reef shell until the corals cover the reef body and no more algae will be attached. (5) Reef formation: After 2-3 years, the reef shell is covered with shellfish. The shellfish inside the reef shell cling to it and grow in clusters, and the reef shell completely sinks to the seabed.

[0031] The three-dimensional structure of the far-shore reef body after the reef is formed can play a role in blocking the flow (redirecting the waves into upwelling) and provide protection for the subsequent reef body; even if strong winds and waves occur, the cone structure can blow away the sea sand accumulated around as soon as possible under the action of the waves, and even if the subsequent reef shell is corroded and broken, the shellfish formed inside it can be tightly clustered together and will not be blown away by the waves.

[0032] The steps of reef making in the above method are as follows: firstly, a mesh attachment rope 5 is connected to the inner wall of the reef shell 1, the attachment rope 5 is wound around the outer wall of the reef tube 3, and then the upper end of the reef tube 3 is connected to the lower end of the reef shell 1 via an upper hook ring 8 and a lower hook ring 9 respectively, and then the attachment ropes 5 are connected between adjacent reef tubes 3, and the bottom of the reef tube 3 is connected to the pile body 4 via a connecting rope.

[0033] The steps of reef construction are as follows: the whole device is arranged in the sea area where reef formation is required, and the pile body 4 is manually inserted into the seabed. Then, oyster and mussel seedlings are placed inside the reef shell 1, and then oyster and mussel seedlings are placed inside the reef tube 3, seaweed seedlings are attached to the attachment ropes 5 of the reef tube 3 and the attachment ropes 5 between adjacent reef tubes 3, and then the conical tube 10 of the pile body 4 is filled with sea sand, and water tanks are planted in the sea sand.

[0034] The above-mentioned stone oyster is the hyoid oyster.

[0035] Due to the buoyancy of seawater, the reef shell 1 and the reef tube 3 float in the seawater. As the oyster and mussel seedlings in the reef shell 1 and the reef tube 3 grow, the weight of the reef shell 1 and the reef tube 3 increases and gradually sinks to the seabed. Moreover, during the growth of oysters and mussels in the reef shell 1, the cover plate 2 of the reef shell 1 can be opened, and oyster and mussel seedlings can be filled into the reef shell 1 at intervals of 10-20 days, until the reef shell 1 sinks to the seabed and the interior of the reef shell 1 is filled with oysters and mussels. The roots of the corals and seaweed seedlings on the outer wall of the reef shell 1 enter the mesh attachment rope 5 inside the reef shell 1 through the mesh holes of the reef shell 1 and attach to the oyster and mussel mixed reef after the reef is formed, which further ensures the stability of the reef after the reef is formed. Then the reef shell gradually sinks. During the process on the seabed, the attachment rope 5 between the reef-forming tubes 3 and the reef-forming tubes 3 is preferentially attached to the seabed, so that the roots of seaweed and seaweed on the attachment rope 5 between the reef-forming tubes 3 and the reef-forming tubes 3 can continue to penetrate into the seabed and continue to grow, further ensuring the stability of the overall structure after the reef is formed, and prolonging the service life. In this process, there is no need to use a bulky reef-forming body to sink to the seabed, and the oysters, mussels, corals, and seaweed on the reef-forming shell 1 adapt to the marine environment during their growth, so as to better adapt to the marine environment after the reef is formed. As the weight of the reef increases, the above-mentioned insertion rod gradually becomes heavier and is inserted into the sand. After the reef is formed, the reef is more stable. Due to the adoption of the above-mentioned structure, the present invention has the advantages of simple structure, high stability, low cost, long service life, and convenient installation.
