Multifunctional artificial algal reef and manufacturing method thereof

Abstract

The invention discloses a multifunctional artificial algal reef, and aims at providing a multifunctional artificial algal reef with which sediment accumulation on main reef surface can be effectively prevented, algal reef surface sediment can be effectively removed, and the influence of the sediment to algae attachment and growth can be avoided. The artificial algal reef comprises a main reef and a plurality of sub reefs arranged on the top surface of the main reef. The top surface of the main reef is a spherical surface protruding upwards. The sub reefs are connected to the main reef through connection columns. Spaces are provided between the sub reefs and the top surface of the main reef. Threads preventing conch and sea urchin climbing are arranged on the connection columns and between the sub reefs and the top surface of the main reef. The invention also discloses a multifunctional artificial algal reef manufacturing method with which algae young sporophyte attachment efficiency under natural conditions can be improved.

Description

technical field

[0001] The invention relates to the field of artificial algal reefs, in particular to a multifunctional artificial algal reef and a manufacturing method thereof. Background technique

[0002] The seaweed farm ecosystem is one of the typical nearshore ecosystems. It uses large algae to absorb, fix, and transfer carbon, nitrogen, phosphorus and other biogenic elements in seawater to reduce eutrophication in water areas and form a variety of marine organisms to grow and inhabit. Locally stable niches can achieve the purpose of increasing biodiversity and restoring fishery resources. In recent years, due to marine environmental pollution, seaweed farms have generally shown a trend of shrinking and degrading worldwide; in coastal rocky bottom sea areas, the vertical distribution pattern of large benthic seaweeds has a tendency to concentrate in nearshore shallow water areas; the reason There are two main aspects: one is that the transparency of seawater decreases...

Embodiment 1

[0031] Embodiment 1: as figure 1 As shown, a multifunctional artificial algae reef includes a lever 11, a floating ball 16, a connecting rope 15, a mother reef 1, a number of sub-reefs 2 arranged on the top surface of the mother reef, and a vertical guide hole arranged in the middle of the bottom surface of the mother reef 4 and the piston body 9 that is slidably arranged in the vertical guide hole.

[0032] The top surface of the mother reef is a spherical surface convex upwards. The top surface of the parent reef is inlaid with several mounting nuts 22 . The bottom edge of the mother reef is provided with several supporting blocks 6 for supporting the mother reef. The bottom of the support block is provided with a triangular claw-shaped support claw 13 .

[0033] The sub-reefs are evenly distributed in the middle of the top surface of the parent reef. The top surface of the sub-reef is a raised spherical surface, and the bottom surface is flat. The top surfaces of the p...

Embodiment 2

[0040] Embodiment 2: a kind of preparation method of multifunctional artificial algae reef, comprises the following steps successively:

[0041] First, the mother reef is poured with concrete, and several mounting nuts for installing sub-reefs are inlaid on the top surface of the mother reef;

[0042] The sub-reef is poured with concrete, and the connecting column is inlaid on the bottom surface of the sub-reef, and the connecting column is a connecting screw;

[0043] Second, the attached mucus is extracted from the seaweed reproductive receptacle in the breeding period, and the attached mucus is evenly spread on the surface of the sub-reef;

[0044] Thirdly, after the attached mucus on the surface of the sub-reef is dry and solidified, the connecting posts are fixed on the mounting nuts.

[0045] Refer to Example 1 for the specific structure of the multifunctional artificial algal reef of this embodiment.
