[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] like Figure 1 and Figure 2As shown, the shell carbon sequestration fish reef provided by the embodiment of the present invention includes: a base frame 100, a shell cage 200 and a fishing cage 300; the shell cage 200 is connected to the base frame 100; and the fishing cage 300 is embedded above the base frame 100.

[0032] Specifically, the fishing cage 300 can capture live fish and is movable relative to the base frame 100, allowing it to be lifted out of the water. The shell cage 200 uses shells enclosed in a mesh container, allowing the shells to be taken from the ocean and returned to the ocean. The shell cage 200 supports the base frame 100, enhancing structural stability. The fishing cage 300 can be lowered and embedded in the base frame 100, allowing it to be submerged in the water. The shell cage 200 can sink to the bottom of the water, utilizing urban shell waste to promote the carbon resource cycle between land and ocean, enhance affinity with the ocean, and achieve greater carbon sequestration.

[0033] It should be noted that the combined use of the shell cage 200 and the fishing cage 300 not only has the effect of carbon fixation, but also can filter seawater and absorb heavy metals, thereby improving the marine environment.

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, in an embodiment of the present invention, the base frame 100 includes: a first ring member 110 and a second ring member 120; the first ring member 110 and the second ring member 120 are coaxial and arranged at intervals; a plurality of shell net cages 200 are connected between the first ring member 110 and the second ring member 120, and the plurality of shell net cages 200 are arranged at intervals along the circumference of the first ring member 110.

[0035] Specifically, multiple shell cages 200 are supported between the first annular member 110 and the second annular member 120. The number of shell cages 200 can range from 5 to 20, and the number of shell cages 200 can be increased or decreased based on the radial dimensions of the first annular member 110 and the second annular member 120. Seawater and impurities in the water can pass through the first annular member 110, the second annular member 120, and the spaces between adjacent shell cages 200, thereby capturing carbon-containing compounds inside the shell cages 200. Furthermore, carbon-containing compounds located outside the base frame 100 can be adsorbed on the outside of the shell cages 200, thereby utilizing shell waste to improve the marine environment and achieve waste recycling.

[0036] Furthermore, the first annular member 110 is located above the second annular member 120 , and the diameter of the first annular member 110 is smaller than the diameter of the second annular member 120 .

[0037] Thus, the first annular member 110 and the second annular member 120 form a truncated cone structure, thereby forming a stable base frame 100 .

[0038] Furthermore, the shell cage 200 is inclined from bottom to top toward the direction close to the axis of the first annular member 110.

[0039] The multiple shell cages 200 are arranged along the conical surface between the first annular member 110 and the second annular member 120. This allows the base frame 100 to increase the length of the shell cages 200 within a limited height dimension, thereby increasing the contact area between the shell cages 200 and marine materials, thereby improving the shells' adsorption efficiency of carbon-containing compounds in seawater. The shell cages 200 are filled with recycled waste shell inorganic materials, which can reduce the cost of artificial reef construction and has the following advantages: (1) a wide source, easy to obtain, and low construction investment; (2) good biocompatibility and no release of alkaline substances; (3) a complex surface structure and high roughness, which can provide a good attachment base for attached organisms and fully utilize carbon fixation energy.

[0040] like Figure 1 As shown, a guide rope 400 is connected between the base frame 100 and the fishing cage 300. The guide rope 400 is a soft rope. When the fishing cage 300 is pulled upward, it can be separated from the base frame 100, thereby lifting the fishing cage 300 out of the water. The shell net cage 200 composed of shells not only absorbs carbon dioxide but also harbors marine organisms, thereby providing food and a living environment for the fish in the fishing cage 300, creating a coexisting environment for fish and marine life. After the marine shell fish reef is deployed, the flow field characteristics around the reef are changed, creating a suitable habitat for the habitat and reproduction of marine life. At the same time, a large number of attached organisms will live and reproduce on the reef, which not only provides abundant bait for fish and other organisms, but also provides a good place for fish to spawn, reproduce, and avoid pests, thereby achieving the ecological effect of improving the habitat, conserving fishery resources, and increasing the amount of marine biological resources. In addition, during the construction of shell fish reefs, systematic measures such as scientifically releasing shellfish seedlings, planting seaweed and algae, and multiplying aquatic organisms can effectively improve the ecological environment of the sea area, conserve offshore fishery resources, increase marine biodiversity, and maintain the safety of the marine ecosystem.

[0041] like Figure 1 and Figure 2 As shown, the guide rope 400 runs through the bottom of the fishing cage 300 to the top of the fishing cage 300. When the top of the guide rope 400 is lifted, the guide rope 400 can make the fishing cage 300 rise steadily.

[0042] Furthermore, the bottom end of the guide rope 400 is connected to the first annular member 110, and the guide rope 400 passes through the bottom of the fishing cage 300 to the top of the fishing cage 300. By lifting the top end of the guide rope 400, the fishing cage 300 can be lifted out of the water.

[0043] like Figure 1 、 Figure 2 and Figure 3 As shown, the fishing cage 300 includes: a support frame 310 , a net body 320 and a one-way net door 330 ; the net body 320 is connected to the support frame 310 , and the one-way net door 330 is installed on the net body 320 .

[0044] Specifically, the net 320 is connected to the support frame 310, which maintains the structural stability of the net 320. The one-way net door 330 is configured as a cone structure with a diameter gradually decreasing from the outside to the inside, so that fish can enter the fishing net cage 300 from the outside and prevent fish that have entered the fishing net cage 300 from escaping.

[0045] Furthermore, a first pointed portion 311 is provided at the bottom of the support frame 310 , thereby forming a conical structure at the bottom of the fishing cage 300 , thereby increasing the surface area of the fishing cage 300 .

[0046] Furthermore, the base frame 100 is provided with a notch adapted to the first tip 311. The first annular member 110 is arranged to form the notch, and the first tip 311 can be inserted into the notch of the base frame 100, thereby keeping the fishing cage 300 stable relative to the base frame 100.

[0047] Furthermore, a second tip 312 is provided at the top of the support frame 310, so that the top of the fishing cage 300 forms a conical structure. The first tip 311 and the second tip 312 are both configured as a polygonal pyramid structure, thereby forming a diamond-shaped structure of the fishing cage 300, which not only improves the structural stability of the fishing cage 300, but also increases the surface area of the net body 320.

[0048] like Figure 1 、 Figure 2 and Figure 3 As shown, the fish reef carbon sequestration method provided by the embodiment of the present invention adopts the shell carbon sequestration fish reef described in the above embodiment and includes the following steps:

[0049] Install the shell cage 200 on the base frame 100;

[0050] The fishing cage 300 is embedded on the top of the bottom frame 100 .

[0051] In the embodiments of the present invention, the fish reef carbon sequestration method achieves the same technical benefits as the shell-based carbon sequestration fish reefs described above, and will not be further elaborated here. Shell-based carbon sequestration fish reefs can host a variety of microorganisms and provide habitats for marine life. Protected by artificial reefs, they can promote ecological aquaculture practices, combating overfishing practices, while also utilizing algae and shellfish to capture carbon dioxide, purifying the surrounding environment.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
