Technical Field
[0001] This utility model relates to the field of artificial algal reef technology, and in particular to an artificial algal reef suitable for deployment along the coast of inner bays. Background Technology
[0002] With the continuous deterioration of the marine ecological environment, marine pollution and overfishing have severely impacted the habitats of marine life. Especially along the inner bay coast, where slow water flow and heavy pollution have made the marine habitat increasingly harsh, artificial reefs, as an emerging marine ecological restoration technology, have been gradually and widely applied in the waters along the inner bay coast to restore ecological balance, promote water purification, and increase biodiversity. Artificial reef technology effectively improves the marine ecological environment and promotes the growth of algae and marine organisms by providing habitats for them. To improve the construction efficiency and effectiveness of artificial reef technology, this invention proposes a new structural design aimed at solving some problems encountered in the construction of traditional artificial reef technologies, providing a more stable and convenient ecological restoration solution.
[0003] Existing artificial reef technologies typically employ relatively simple structures, utilizing natural or artificial materials such as rocks and concrete to construct the reefs. These traditional structures promote the growth of algae and other aquatic organisms by providing an attachment platform for marine life. However, these reefs face several challenges in practical applications, such as complex, time-consuming, and inefficient construction processes. Furthermore, due to the lack of effective attachment structures and stability, algae growing on the reefs are prone to detachment and exhibit slow growth rates, resulting in insignificant restoration effects. Although some reef designs have attempted to introduce reinforced structures and attachment surfaces, the technical challenge of sustaining algal growth and attachment in the long term remains.
[0004] Especially in the coastal areas of inner bays, due to slow water flow and poor water quality, traditional algal reefs struggle to provide a stable habitat, hindering algal growth. Therefore, ensuring the stability of the algal reef while enabling rapid algal attachment and stable growth has become a key technical challenge in improving the restoration effect of artificial algal reef technology. This invention provides an efficient, convenient, and stable solution by improving the structure and design of artificial algal reef technology, effectively addressing the difficulties faced by traditional artificial algal reef technology in its construction and growth process, and enhancing the practicality and long-term effectiveness of artificial algal reef technology. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an artificial algal reef suitable for deployment along the coast of inner bays, aiming to improve the problems of traditional artificial algal reefs being troublesome to produce, slow to grow, and prone to falling off.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an artificial algal reef suitable for deployment along the coast of an inner bay, comprising:
[0007] A base, which is used to support the entire assembly;
[0008] The column is fixedly connected to the top of the base at its bottom. The column has a spiral groove inside, which improves the adhesion and binding of algae.
[0009] Frame 1 and Frame 2, the outer walls of both Frame 1 and Frame 2 are fixedly connected to the outer wall of the column, and both Frame 1 and Frame 2 have mounting grooves inside, and both Frame 1 and Frame 2 are used to support oyster shells.
[0010] A wire mesh, the outer wall of which fits into an installation groove, is used to fix oyster shells.
[0011] Furthermore, a partition is fixedly connected inside the base, and a groove is provided inside the base.
[0012] Furthermore, the base retains a certain amount of water during low tide through its grooves, which helps to increase the water supply needed by algae, marine larvae, and small organisms.
[0013] Furthermore, the base is 50cm long.
[0014] Furthermore, the groove inside the base is 5cm deep.
[0015] Furthermore, the base is used to enhance the adsorption of algae and heavy metals.
[0016] This utility model has the following beneficial effects:
[0017] In this invention, the base retains a certain amount of moisture when the tide recedes, maintaining the water required by the algae and organisms. Oyster shells are placed between the wire mesh with their backs facing up. The spiral grooves on the outer wall of the frame facilitate the attachment and binding of algae to the outer wall of the pillars, achieving the effect of easy stacking of algal reefs. This solves the problems of traditional artificial algal reefs being troublesome to make, and algae being difficult to attach to, slow to grow, and easy to fall off, thus improving the practicality of artificial algal reefs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-3This utility model provides an embodiment of an artificial algal reef suitable for deployment along the coast of an inner bay, comprising: a base 1, which supports the entire structure and provides a stable support structure for other components. The base 1 is 50cm long and has a groove 8 with a depth of 5cm inside, used to retain a certain amount of water during low tide, maintaining the moisture required by algae and small marine organisms, and ensuring a humid environment for algae growth. A partition 7 is also fixedly connected inside the base 1 to further enhance water distribution and prevent water loss, increasing the attachment area of algae and the stability of its growth environment. The design of the base 1 not only helps to improve the attachment effect of algae, but also helps to absorb heavy metals in the water, further improving water quality and enhancing ecological restoration functions. A column 2 is fixedly connected to the top of the base 1 at its bottom. The column 2 has a spiral groove 6 inside, which improves the adhesion and binding of algae, allowing algae to better attach to the surface of the column 2, improving its growth conditions and stability. The spiral groove 6 is designed to allow water to flow on the surface of the column 2, creating a microenvironment conducive to algae growth. It also enhances the stability of algae attachment, preventing them from being washed away by tidal changes. Frames 4 and 5 are fixedly connected to the outer wall of the column 2. Both frames 4 and 5 have mounting grooves 3 inside. Frames 4 and 5 support oyster shells, providing a fixed position for stable attachment and a habitat for algae. The design of frames 4 and 5 makes the entire structure more stable, providing necessary support for stable attachment of oyster shells and algae growth. The wire mesh 9, with its outer wall interlocking with the mounting grooves 3, is used to fix the oyster shells. The wire mesh 9 design ensures that oyster shells will not detach and provides a suitable attachment surface for algae, enhancing their growth environment. It also prevents oyster shell loss, making the artificial algal reef more durable and stable. The base 1, through the combined design of grooves 8 and partitions 7, effectively retains moisture at low tide, ensuring that algae receive the necessary water environment during growth, improving algal adhesion and growth efficiency. Simultaneously, the grooves 8 in the base 1 can effectively absorb heavy metals in the water, promoting water purification and playing a certain role in restoring the aquatic environment.
[0025] Working principle: When using this artificial algal reef suitable for deployment along the inner bay, the base 1 is first divided into three grooves 8 by two partitions 7 inside, which allows a certain amount of water to be retained inside during low tide, maintaining the water required by the algae and organisms. Then, two layers of wire mesh 9 are set on the top of the base 1. The wire mesh 9 is fixed by frame one 4 and frame two 5. Oyster shells are placed between the two layers of wire mesh 9, with the back of the oyster shells facing up. At the same time, the spiral grooves 6 opened on the outer wall of frame two 5 facilitate the attachment of algae to the outer wall of the column 2. The base 1 is made of ecological concrete and oyster shell fragments, which increases the porosity and improves the adsorption of algae on the base 1. It can also adsorb heavy metals and improve the ecological environment.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
