Description

Technical Field

[0001] This utility model relates to the field of coral cultivation technology, and more specifically, to a magnetic adsorption type seabed cultivation base based on coral fragments. Background Technology

[0002] Coral reefs, as an important part of the marine ecosystem, are increasingly degraded due to climate change, marine pollution and human activities. Artificial coral transplantation has become one of the core means of coral reef restoration.

[0003] Currently, in the process of transplanting coral fragments, nylon ropes, steel wires, cable ties, etc. are usually used to bind the coral fragments to the seabed culture support. These fragments are easily loosened or even broken by seawater erosion and the attachment of marine organisms (such as shellfish and algae), which greatly reduces the survival rate of the coral fragments. In addition, underwater binding operations require divers to work precisely for a long time, and each coral fragment needs to be bound one by one. The operation is time-consuming, labor-intensive, and inefficient.

[0004] To solve the above problems, there is an urgent need to develop a coral cultivation base that can be quickly fixed, is easy to operate, and has high stability. Utility Model Content

[0005] To address the problems of poor stability and low operational efficiency of existing coral fragment cultivation bases, the purpose of this invention is to provide a magnetic adsorption seabed cultivation base based on coral fragments, which enables rapid assembly and disassembly of coral fragments and secure fixation, while reducing the underwater work intensity of divers and improving coral cultivation efficiency and survival rate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A magnetic adsorption-type seabed culture base based on coral fragments includes a culture bed frame, a fixed support, a base, a culture net, a culture base, and a fastening component; The culture bed frame is a rectangular frame structure used to support and fix other structural components; The fixed support pillars are provided in four sets, which are respectively fixed at the bottom of the four corners of the culture bed frame to support the culture bed frame from the bottom and separate it from the seabed; The base is located at the bottom of the fixed support column and buried in the seabed, and is used to support and fix the entire device by gravity. The culture net is made of multiple rigid support rods connected in a cross shape, forming a mesh structure. It is fixed inside the culture bed frame, and its edges are fixedly connected to the inside of the culture bed frame to support and fix the culture base. The cultivation base is provided in several groups, and each group of cultivation bases is located at the node of the cultivation net to fix coral fragments; the cultivation base includes a movable base and a fixed base; the fixed base is fixed at the node of the cultivation net, and the movable base is detachably mounted on the fixed base; The fastening assembly consists of four sets, located at the four corners of the culture bed frame, for further securing the device to the seabed.

[0007] Furthermore, the fixed base has a plug-in groove on its top, the movable base has a positioning groove on its top for connecting and fixing coral fragments, the movable base has a stepped groove at its bottom that matches the plug-in groove, the bottom surface of the movable base is fitted with a first magnet plate, and the bottom of the plug-in groove is fitted with a second magnet plate that can be magnetically attracted and connected to the first magnet plate.

[0008] Furthermore, the fixed base has multiple sets of limiting plates evenly distributed around its circumferential surface, and the movable base has limiting slots adapted to the limiting plates on its circumferential surface, with the limiting plates engaging with the limiting slots.

[0009] Furthermore, the bottom of the fixing base is provided with a cross-shaped groove, the specifications of which are adapted to the node specifications of the culture net. The fixing base is secured to the node of the culture net through the cross-shaped groove and connected by welding.

[0010] Furthermore, the fastening assembly includes a first pull ring, a steel wire rope, a second pull ring, and a ground cone; the first pull ring is fixed at the corner of the culture bed frame, the second pull ring is fixed on the ground cone, and the first pull ring and the second pull ring are connected by a steel wire rope.

[0011] Furthermore, the base is a cylindrical structure made of cast concrete, and the lower end of the fixed support is embedded in the base.

[0012] Furthermore, adjacent sets of fixed supports are connected by connecting supports.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The cultivation base in this utility model adopts a dual fixing structure of magnetic adsorption and limiting engagement. The strong adsorption force of the first and second magnetic plates can realize the rapid adhesion of the movable base and the fixed base. The engagement of the limiting plate and the limiting slot can prevent the movable base from rotating or falling off, effectively resisting the risk of loosening caused by seawater erosion and marine organism attachment. At the same time, the dual fixing structure formed by the base and the fastening components ensures that the entire device does not shift, further guaranteeing a stable growth environment for coral fragments and improving the survival rate.

[0014] 2. The movable base and the fixed base of this utility model are detachably connected. Divers do not need to tie coral fragments one by one. They only need to align the movable base with the coral fragments and press it with the insertion slot of the fixed base to achieve magnetic adsorption and limiting engagement to complete the fixation. This greatly improves the efficiency of underwater operations, reduces the labor intensity of divers, and improves the ease of operation.

[0015] 3. The mesh support structure formed by the culture bed frame and the culture net allows for the installation of multiple culture bases on a single device, enabling the simultaneous cultivation of multiple coral fragments. The three-dimensional frame design of the fixed support pillars and connecting support pillars not only prevents coral fragments from contacting seabed sediment but also ensures smooth seawater flow, providing sufficient oxygen and nutrients for the coral fragments and meeting the cultivation needs of large-scale coral reef restoration.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1: like Figures 1 to 6 As shown, this embodiment provides a magnetic adsorption type seabed cultivation base based on coral fragments, including a cultivation bed frame 2, a fixed support column 4, a base 5, a cultivation net 6, a cultivation base 3, and a tensioning component 1.

[0027] The culture bed frame 2 is a rectangular frame structure made of corrosion-resistant stainless steel. It is used to support and fix the culture net 6, the culture base 3 and other structural components. Its frame size can be adjusted according to the cultivation needs to ensure the stability of the overall structure and its resistance to seawater impact.

[0028] The fixed support column 4 has four sets, which are vertically fixed at the bottom of the four corners of the culture bed frame 2. They are made of solid metal rods and their height is 0.5-1m. They can be adjusted according to the seabed depth and sediment thickness. They are used to support the culture bed frame 2 from the bottom, so that the culture bed frame 2 is kept separate from the seabed sediment and the coral fragments are prevented from being covered by mud and sand.

[0029] Among them, the two adjacent fixed support columns 4 are horizontally connected by connecting support columns 41. The connecting support columns 41 and the fixed support columns 4 are fixed by welding or bolts to form a three-dimensional stable structure of rectangular frame + vertical support, which improves the overall wind and wave resistance of the device.

[0030] The base 5 is located at the bottom of the fixed support column 4. It is a cylindrical structure made of concrete. The lower end of the fixed support column 4 is vertically buried inside the base 5 at a depth of not less than 0.2m and fixed by concrete curing. The base 5 is buried in the seabed sediment. It uses its own weight and the stability of the concrete to support and fix the bottom of the device and prevent the device from shifting due to seawater flow.

[0031] The cultivation net 6 is made of multiple rigid support rods, such as stainless steel metal rods, connected in a cross shape to form a mesh structure. It is fixed inside the cultivation bed frame 2 by bolts or welding, and the edges are tightly fixed to the inner side wall of the cultivation bed frame 2. The function of the cultivation net 6 is to provide uniform support points for the cultivation base 3, while facilitating seawater circulation and providing sufficient oxygen and nutrients for coral fragments.

[0032] The cultivation base 3 is provided in several groups, the number of which is consistent with the number of nodes in the cultivation net 6. Each group of cultivation base 3 is located at a node of the cultivation net 6 and is used to fix coral fragments. The cultivation base 3 includes a movable base 31 and a fixed base 33. The fixed base 33 is a cylindrical structure with an insertion groove 37 at the top. A second magnet plate 38 is embedded at the bottom of the insertion groove 37. The second magnet plate 38 is a neodymium iron boron strong magnet with a nickel-plated surface for corrosion protection. 4-6 sets of limiting plates 36 are evenly distributed around the circumference of the fixed base 33. A cross-shaped buckle groove 39 is provided at the bottom of the fixed base 33. The specifications of the cross-shaped buckle groove 39 are adapted to the node specifications of the culture net 6. The fixed base 33 is secured to the node of the culture net 6 through the cross-shaped buckle groove 39 and permanently fixed by welding to ensure that there is no relative displacement between the fixed base 33 and the culture net 6.

[0033] The movable base 31 is a cylindrical structure with the same diameter as the fixed base 33. A positioning groove 32 is provided on the top for placing and fixing coral fragments. The bottom of the movable base 31 is provided with a stepped groove that matches the insertion groove 37 of the fixed base 33. The height of the step is the same as the depth of the insertion groove 37. A first magnet plate 35 is embedded in the stepped groove, which has the opposite polarity to the second magnet plate 38 to ensure magnetic adsorption.

[0034] The movable base 31 has a limiting slot 34 on its circumferential surface that is compatible with the limiting slot 36 of the fixed base 33. The number of slots is the same as that of the limiting slot 36. The movable base 31 is engaged with the insertion slot 37 of the fixed base 33 through a stepped groove. It is initially fixed by the magnetic adsorption of the first magnet plate 35 and the second magnet plate 38. Then, it is fixed again by the engagement of the limiting slot 34 with the limiting slot 36, so as to prevent the movable base 31 from rotating or falling off due to the impact of seawater.

[0035] The fastening assembly 1 has four sets, which are respectively located at the four corners of the culture bed frame 2. They are used to pull and fix the culture bed frame 2 from all sides of the device, further improving the overall stability of the device. The fastening assembly 1 includes a first pull ring 11, a steel wire rope 12, a second pull ring 13, and a ground cone 14. The first pull ring 11 is made of stainless steel and is fixed to the outer wall of the corner of the culture bed frame 2 by welding. The ground cone 14 is a conical structure with a length of 0.8-1.2m and a hardened metal tip, which is used to drive into the seabed sediment to provide a fixing point. The second pull ring 13 is fixed to the top of the ground cone 14 and has the same specifications as the first pull ring 11. The steel wire rope 12 is made of corrosion-resistant stainless steel wire and its two ends are fixedly connected to the first pull ring 11 and the second pull ring 13 by buckles. When pulled, the steel wire rope 12 is kept in a taut state, forming a double fixing structure of bottom base 5 + surrounding reinforcement.

[0036] Example 2: This embodiment provides the working principle of a magnetic adsorption-type seabed cultivation base based on coral fragments: In actual use, the device is transported to the target seabed area and the base 5 is buried in the seabed sediment. The first pull ring 11 is connected to the second pull ring 13 on the corresponding ground cone 14 by the steel wire rope 12. After tightening the steel wire rope 12, the four ground cones 14 are driven into the seabed sediment around the culture bed frame 2. On shore, the base of the coral fragment is glued and fixed to the positioning groove on the movable base 31 using special glue. The diver carries the coral fragment to be cultivated and dives into the seabed. He aligns the stepped groove at the bottom of the movable base 31 with the insertion groove 37 of the fixed base 33, presses the movable base 31, and magnetically attaches the first magnetic plate 35 and the second magnetic plate 38 together. At the same time, the limiting plate 36 is inserted into the limiting groove 34, thus completing the fixation of the coral fragment. To replace or adjust a broken coral branch, divers simply need to pull the movable base 31 upwards to overcome the magnetic attraction and the elasticity of the limiting plate 36, making the operation convenient.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
