Description

Technical Field

[0001] This utility model relates to the field of marine ecological restoration equipment, and in particular to a heat-resistant coral acclimatization pool. Background Technology

[0002] Coral reefs are a vital component of marine ecosystems, possessing immense biodiversity and ecosystem service value. However, global warming has led to abnormally high seawater temperatures, causing coral bleaching and even death. Traditional coral conservation techniques primarily focus on artificial restoration or transplantation, but lack systematic acclimatization to improve coral heat tolerance. Current technologies largely rely on constant-temperature laboratory environments for coral acclimatization, failing to simulate the temperature fluctuations of the natural intertidal zone, resulting in insufficient adaptability of acclimatized corals in the wild.

[0003] Intertidal rock pools experience dramatic temperature fluctuations due to the influence of tides and sunlight, allowing corals living in this environment to gradually develop heat tolerance. However, natural rock pools are geographically limited and cannot be used on a large scale. Current artificial acclimatization facilities mostly use fixed temperature control, lack simulation of dynamic temperature fluctuations, and are complex and costly. Therefore, there is an urgent need for a low-cost, easy-to-install coral acclimatization device that can simulate natural temperature fluctuations to improve coral heat tolerance and ecological restoration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a heat-resistant coral acclimatization pond, solving the technical problem that existing artificial acclimatization facilities use fixed temperature control and lack simulation of dynamic fluctuation environments. This invention provides an acclimatization pond with a simple structure, corrosion resistance, and scalable application. By simulating the temperature fluctuation environment of the intertidal zone, it acclimatizes corals to withstand heat and enhances their ability to adapt to climate change.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A heat-resistant coral acclimatization pool includes a pool body, a bottom plate at the bottom of the pool body with a plurality of fixing holes spaced apart, a coral support inside the pool body, and two cover nets at the top of the pool body, the two cover nets being configured as a semi-circular structure.

[0006] Furthermore, the pool body is configured as a hollow cylindrical structure. Furthermore, the bottom plate is configured as a circular structure, and the pool body is connected to the middle of the bottom plate.

[0007] Furthermore, the interior of the coral support is uniformly distributed with square grids, and the coral support is made of glass fiber reinforced composite material.

[0008] Furthermore, the interior of the cover net is uniformly distributed with honeycomb-shaped mesh.

[0009] Furthermore, the cover net is provided with a skeleton, and the tail of the skeleton is provided with a barb, which is hooked onto the top edge of the pool body.

[0010] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: The acclimatization pond designed in this invention provides highly efficient acclimatization: through open design and natural exposure, it provides corals with an environment with large temperature fluctuations through natural tidal rise and fall and intertidal temperature difference (daily fluctuation of 5-10℃), thereby improving the corals' ability to adapt to climate change.

[0011] The acclimatization pool structure of this invention is stable: the fixing hole design ensures that the pool body does not shift under tidal impact.

[0012] The acclimatization pool designed in this invention is low-cost and easy to maintain: it does not require complex temperature control equipment, relies on natural conditions to achieve temperature fluctuations, and has low operation and maintenance costs.

[0013] The acclimatization pond designed in this invention is scalable: the modular design supports multiple ponds in parallel, meeting the needs of large-scale coral acclimatization. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0017] like Figure 1-3As shown, a heat-resistant coral acclimatization pond includes a pond body 1. The bottom of the pond body 1 is provided with a bottom plate 6. The bottom plate 6 is provided with a plurality of fixing holes 2 at intervals. The fixing holes 2 are used for anchoring to intertidal reefs. The diameter of the fixing holes 2 can be set to 32mm, and the spacing of the fixing holes 2 can be set to 0.6m. The interior of the pond body 1 is provided with a coral support 5. The top of the pond body 1 is provided with two cover nets 3, and the two cover nets 3 are designed with a semi-circular structure.

[0018] like Figure 1-2 As shown, the pool body 1 is a hollow cylindrical structure with an open top. The pool body 1 can be made of polypropylene (PP) sheet, and can be welded from PP sheets. The diameter of the pool body 1 can be 2.00m, the circumferential thickness can be 10mm, and the depth can be 0.8m. The bottom plate 6 is a circular structure, connected to the pool body 1 at the center. The bottom plate 6 can be made of PP sheet. The diameter of the bottom plate 6 can be 2.40m, and the thickness can be 15mm. When the pool body 1 and the bottom plate 6 of this invention are made of PP sheet, the PP material is corrosion-resistant and impact-resistant, and the fixing hole design ensures that the pool body does not shift under tidal impact.

[0019] like Figure 3-4 As shown, the coral support 5 has a uniformly distributed square grid inside, and the coral support 5 is made of glass fiber reinforced composite material. The length of the coral support 5 can be set to 1.50m, the width of the coral support 5 can be set to 1.20m, and the height of the coral support 5 can be set to 50mm. A glass fiber reinforced composite coral support with a length of 1.50m, a width of 1.20m, and a height of 50mm is placed in the pool (multiple layers can be placed to adjust the height as needed). The coral support 5 has a uniformly distributed square grid with a side length of 50mm and a wall thickness of 5mm. Corals can be fixed on the coral support 5 using various methods such as seedling holders and cable ties. The cover net 3 has a uniformly distributed honeycomb grid inside. The cover net 3 is equipped with a skeleton 4, and the tail of the skeleton 4 is equipped with barbs, which are hooked to the top edge of the pool body 1. The top of the pool is covered with two semi-circular nets, each made of high-density polyethylene (HDPE) with an internal honeycomb mesh of 25mm sides and 316 stainless steel. The acclimatization pool is directly exposed to the intertidal environment. The nets prevent the impact of marine debris and other human factors on coral acclimatization, while not affecting the periodic temperature fluctuations formed by natural tidal rise and fall and solar radiation.

[0020] One of the preparation and use processes of the acclimatization pool: A cylindrical pool with a base diameter of 2.00m and a depth of 0.80m was welded from 10mm thick PP sheets. The bottom was reinforced with PP sheets with a base diameter of 2.40m and a thickness of 15mm. Eight 32mm diameter fixing holes were evenly drilled in the bottom of the pool, with a spacing of 0.60m, for anchoring bolts to fix it to the intertidal base. A glass fiber reinforced composite coral support measuring 1.50m long, 1.20m wide, and 50mm high is placed in the pool. The support has a uniformly distributed 50mm square mesh inside, with a wall thickness of 5mm. The corals are fixed to the support using seedling trays and cable ties. The height of the support can be adjusted by placing multiple layers of seedling trays according to the specific acclimatization situation. Two semi-circular cover nets are installed on the top of the pool. Each cover net is made of high-density polyethylene (HDPE) with a honeycomb grid with an internal side length of 25mm and 316 stainless steel rods. Each cover net has 5 rods as the skeleton, which are welded at the top and have barbs at the tail to fix it to the top edge of the acclimatization pool. The coral fragments to be acclimated are fixed onto a support substrate, and the acclimation pool is installed in the mid-high tide area of ​​the intertidal zone. Through natural tidal fluctuations and solar radiation, the water temperature in the pool fluctuates by 5-10℃ daily for acclimation for 3-6 months. After acclimation, the heat-resistant corals are transplanted to the target sea area.

[0021] In an experiment conducted on Weizhou Island in the South China Sea, the survival rate of acclimatized corals increased by 40% during the high-temperature summer season, and the bleaching rate decreased to below 15%. The pool structure showed no deformation after a year of tidal impact, and the operation and maintenance costs were only 20% of those of traditional temperature control facilities.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
