Description

A composite artificial algae reef

technical field

The invention relates to a composite artificial algae reef combining algae transplantation and seedling attachment.

Background technique

Algae farms are an important part of marine ecosystems, which can provide habitats, spawning, brooding, baiting and avoiding enemies for a variety of marine organisms. It plays an important ecological role in improving the carbon sequestration capacity of the ocean. However, since the 1980s, my country's coastal natural algae farms have been severely degraded, mainly due to land reclamation, land-based pollution, and unreasonable fishery production. Therefore, the restoration and reconstruction of the algae farm is urgent. The placement of artificial algae reefs is an important measure for the restoration and reconstruction of algae farms. In recent years, a series of related researches have been carried out on the materials, shapes, and functions of reefs.

Currently commonly used algae reef materials include reinforced concrete, stones and steel; the shapes are mostly box-shaped, cylindrical, triangular, etc.; the functional design focuses on increasing the adhesion surface of spores, improving the adhesion ability of seaweed, and preventing the feeding of algae-eating organisms Wait. Due to the low affinity between concrete and seaweed seedlings, the attachment rate of algal reef seedlings with concrete surface is low; in order to increase the attachment area of spores, most algal reefs are designed into a large cylindrical or box shape, which is not easy to carry , and most of the algae reefs are still in the form of single seedling attachment or algae transplantation, and the efficiency and success rate of repairing and rebuilding the algae field are low.

Contents of the invention

In order to solve the above problems in the prior art, the present invention provides a composite artificial algae reef, including algae-growing reef and seedling reef, the algae-forming reef includes a solid base and several seedling ropes, and the algae-growing reef is attached to the algae-growing reef Several blocks on the reef, the seedling reefs are attached with seaweed seedlings, and the seedling reefs are fastened to the algae-forming reefs.

The technical scheme that the present invention takes is as follows:

A composite artificial algae reef, including an algae-forming reef and a seedling reef, the algae-forming reef includes a solid base, the upper surface of the solid base is embedded with a metal frame with the same shape and size as the upper surface, and a shell net is arranged inside the metal frame A metal pole is inlaid in the center of the upper surface of the bag, and a steel ring is welded to the upper end of the pole. A number of seedling ropes are fixed between the metal frame and the steel ring. Seaweed seedlings are attached.

The solid base is a triangular platform, a quadrangular platform or a multi-prism platform, and the seedling reef is a trapezoid with the same size and shape as the side of the solid base.

Bolts are provided on the side of the solid base, and the seedling reef has a central hole corresponding to the position of the bolt, and the seedling reef is fixed on the side of the solid base through the bolts.

A PVC pipe is embedded in the central hole of the seedling reef.

Shells are inlaid on the surface of the seedling reef.

Seaweed is clamped on the seedling rope.

Both the solid base and the seedling reef are formed by pouring concrete.

The invention adopts the form of combining seedling attachment and algae-forming transplantation, uses seedling reefs to attach seedlings and seedlings to clip seedlings to transplant into algae, ensures the effect of seaweed attachment, shortens the repair period of the seaweed field, and improves the restoration and reconstruction of the algae field The success rate is high; the shells with high affinity to seaweed are used to inlay the surface of the reef, which increases the attachment rate of the seedlings; the seedling reef is separated from the base that acts as a fixation, and the seedling reef is fixed on the base with screws, which is firm , Durable, and the seedling reef is small and light for easy handling; the net bag made of discarded shells is placed in a metal frame, and the spores of the algae on the seedling rope are released and attached to form a biophilic reef. The resource utilization of discarded shells is economical and convenient, and the shells of oysters and mussels are taken from nature, which are good bio-fed substrates.

The present invention utilizes shellfish surface roughness, porous structure and gaps between shellfish to provide a good habitat for microorganisms, bait organisms, etc., and can also provide an optimal environment for seaweed to take root, and finally form a habitat for fish and shellfish. When the seaweed reproduces to a certain extent, it can produce a large amount of oxygen, reduce carbon dioxide, and play a role in purifying water quality and preventing red tides, so as to promote the recovery of benthic biological resources and marine ecological environment.

detailed description

Example:

See Figure 1-4,

The composite artificial algae reef of the present invention includes algae-forming reef and seedling reef. The algae-forming reef includes a solid base 100 with a quadrangular platform. The upper surface of the solid base is inlaid with a metal frame 200 with the same shape and size as the upper surface, and a shell net bag. 300 is placed in a metal frame to provide a good fixation base for spores and a habitat for benthic organisms. A metal pole 400 is inlaid in the center of the upper surface of the solid base, and a steel ring 500 is welded to the top of the metal pole. One end of the seedling rope 600 is fixed on the steel ring, and the other end is fixed on the metal frame, arranged radially and evenly, and fixed on the seedling rope. There is seaweed 601. The seedling reef 700 is fastened to the side of the solid base of the algal reef, the surface of the seedling reef is inlaid with shells 701, and the seedling reef is attached with seaweed seedlings. The seedling reef adopts a trapezoidal structure, which can be attached to each side of the four-sided prism. A raised bolt 101 is vertically fixed on the side of the base, and a central hole 702 is set on the seedling reef, corresponding to the fixed raised bolt on the base, and the seedling reef is fixed on the side of the solid base by bolts and nuts. For convenience, the seedling reef is connected to the bolts on the base through the center hole, and the center hole is embedded with a PVC pipe.

Both the solid base and the seedling reef are poured concrete. The seedling reef is immersed in the seedling pond containing the germ cells of seaweed, and after the germ cells of the seaweed are successfully attached to the seedling reef and grows into seedlings, the seedling reef is fixed to the base of the quadrangular platform by nuts. The seaweed is fixed on the seedling rope of the algae reef, and then it can be put into the seabed. The above-mentioned composite artificial algal reefs are arranged in a large area to form an artificial algal reef field.

The above description is only a preferred embodiment of the present invention, but the present invention should not be limited to the content disclosed in this embodiment. Therefore, all equivalents or modifications that do not deviate from the principles disclosed in the present invention fall within the protection scope of the present invention.
