Description

Technical Field

[0001] This utility model relates to the field of coral ecological restoration, and in particular to a device for the restoration and fixation of natural debris of Duncanopsammia peltate. Background Technology

[0002] Coral reefs are among the most complex and important marine ecosystems on Earth. However, due to climate change, marine pollution, and human activities, the degradation of coral reefs worldwide is becoming increasingly severe. Duncan's shield coral, a type of coral tolerant of turbid waters, holds significant ecological importance in the context of drastic ecosystem changes. However, due to its disc-like structure, Duncan's shield coral is highly susceptible to tipping and fragmentation, especially in areas with frequent human activity. Traditional coral restoration often focuses on corals like staghorn coral, which have independent support points and are relatively easy to fix and restore. However, due to its sheet-like morphology, traditional restoration methods and supports for Duncan's shield coral are significantly insufficient in terms of stability, making them unsuitable for its restoration needs. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide a device for the repair and fixation of natural debris of shield-shaped Duncan sand coral. The device has a stable and simple structure, is designed specifically for shield-shaped Duncan sand coral, matches the shape of its natural debris, is suitable for marine areas with frequent human activities, and can improve the effect of coral repair.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for restoring and fixing natural fragments of shield-shaped Duncan coral includes a coral base and a threaded connection assembly; the coral base is used to connect to the shield-shaped Duncan coral and has a through hole; the threaded connection assembly is used to screw the coral base to the restoration frame.

[0006] The threaded connection assembly includes a screw, a flat washer, and a nut, and connects the coral base to the restoration frame through a through hole on the coral base.

[0007] After the threaded connection assembly connects the coral base to the repair frame, the screws of the threaded connection assembly are not exposed.

[0008] All threaded connection components are made of ceramic.

[0009] The coral base is made of clay.

[0010] The coral base is bonded to the coral using a two-component epoxy resin adhesive.

[0011] The coral base has an array of through holes arranged with a spacing of 7 mm or more between the through holes.

[0012] Compared with the prior art, the beneficial effects achieved by the technical solution of this utility model are:

[0013] 1. This utility model has a stable and simple structure, is designed specifically for shield-shaped Duncan sand coral, matches the shape of its natural fragments, is suitable for marine areas with frequent human activities, and can improve the effect of coral restoration.

[0014] 2. The silicon in traditional concrete bases promotes diatom growth and competes with corals. This invention effectively avoids this problem by using a clay coral base.

[0015] 3. This utility model uses a ceramic threaded connection component. The ceramic material avoids the corrosion and expansion of traditional metal bolts in the seawater environment, which would hinder the subsequent disassembly of the device. The utility model also adopts a screw-out design, which prevents organisms from attaching to the screw and facilitates the subsequent disassembly of the device, thus enabling the successful transplantation and restoration of corals.

[0016] 4. This utility model uses a two-component epoxy resin adhesive to bond coral and coral base. The two-component epoxy resin adhesive not only cures quickly and has strong adhesion, but also has a certain degree of plasticity, filling the irregular gaps between the coral and the coral base. Therefore, it can not only be operated quickly, but also make the connection between the coral and the coral base more firm and tight.

[0017] 5. The coral base of this utility model is provided with an array of through holes, which facilitates water flow and can also prevent the accumulation of resuspended sediments. Attached Figure Description

[0024] To make the technical problems, technical solutions and beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figures 1-3 As shown in the figure, this embodiment provides a device for repairing and fixing natural fragments of Duncan's coral, including a coral base 3 and a threaded connection assembly; a two-component epoxy resin adhesive 7 is used to bond the coral fragment 6 and the coral base 3.

[0027] The coral base 3 is a clay disc with a diameter of 10cm and a thickness of 1cm. The disc surface has through holes 5 with a diameter of 7mm evenly distributed. The through holes 5 are arranged in an array, and the interval between the through holes 5 is greater than or equal to 7mm.

[0028] The threaded connection assembly includes a screw 1, a flat washer 2, and a nut 4, all of which are made of ceramic. The screw 1 has a thread diameter of 6mm, a thread pitch of 1mm, and a head thickness of 4mm. The nut 4 is hexagonal, fits with the screw 1, has a thickness of 4mm, and the hexagonal side length is 10mm. The threaded connection assembly has sufficient strength and engagement force to ensure stable underwater fixation.

[0029] The repair frame 8 is a perforated plate, and the coral base 3 and the repair frame 8 can be connected by multiple threaded connection components. For example... Figures 3-5 As shown, the coral base 3 is securely fixed to the repair frame 8 using three threaded connection components, ensuring its stability and reliability in the seabed environment. The length of the screw 1 must match the combined thickness of the coral base 3 and the repair frame 8 after connection, and the screw 1 must not protrude.

[0030] The specific steps for planting corals using this device are as follows:

[0031] 1. Select a shield-shaped Duncan coral growth area with a water depth of 3-5m and a flat bottom in the Dongshan Coral Provincial Nature Reserve of Zhangzhou City as the deployment area for the restoration and fixing device.

[0032] 2. During installation, pass screw 1 through flat washer 2, then through the through hole 5 in the center of coral base 3, and install it on the perforated restoration frame 8. Hold coral base 3 with one hand, and use the other hand to screw flat washer 2 and nut 4 together from below the restoration frame along the threads until they are locked.

[0033] 3. Take an appropriate amount of two-component epoxy resin 7, mix it well, and then shape it into a groove according to the cross-section of the coral fragment 6. Place it on the coral base 3, press the coral fragment 6 firmly onto the coral base 3, and transfer it underwater after initial curing.

[0034] The restoration work on the natural fragments of Duncan's shield coral was carried out in June 2024. A total of 69 natural fragments were collected. After 5 months of monitoring, 60 fragments survived, and the coral cups showed obvious signs of expansion, with remarkable results.

[0035] Obviously, the above embodiments are merely specific examples of this utility model, intended to better illustrate the principles and features of this utility model, and should not be considered as limitations on its implementation. Those skilled in the art can make various equivalent modifications and variations under the guidance of this invention, and all such variations should fall within the protection scope of this utility model. All alterations, equivalent substitutions, and improvements made within the spirit and principles of this utility model are included within the protection scope of the claims of this utility model.
