Algal reef with sediment self-cleaning function

Abstract

The invention discloses an algal reef with a sediment self-cleaning function and aims to provide an algal reef having the functions of clearing surface sediment by ocean current and preventing the sediment from affecting algal attachment and growth. The algal reef comprises a base and a hollow reef body arranged above the base. The center-of-gravity of the algal reef is located on the base or in the lower portion of the hollow algal reef body close to the base; the top of the hollow algal reef body is provided with a flow guide member; a plurality of ocean current guide-in passages communicated with an inner cavity of the hollow algal reef body are evenly and peripherally arranged in the side of the flow guide member; inner ports of the ocean current guide-in passages face down; the edge of the inner port of each ocean current guide-in passage is provided with a dented circular step; a guide mesh cover is arranged below each circular step; a floating cover plate for covering the inner port of the corresponding ocean current guide-in passage is arranged in each circular step; the sidewall of the hollow algal reef body is provided with a plurality of arc guide passages, and the arc guide passages form scour slits in the outer side of the hollow algal reef body.

Description

technical field [0001] The invention relates to the field of algae reefs, in particular to an algae reef with the function of sediment self-cleaning. 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, and large seaweeds cannot ...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the artificial algae reefs in the prior art cannot be removed after the sediments on the surface of the algae are accumulated, which seriously affects the attachment of seaweed sporophytes and the growth and survival after attachment, and provides a method that can use ocean currents to remove algae. The sediment on the surface of the reef, the algae reef with the self-cleaning function of the sediment to avoid the influence of the sediment on the attachment and growth of algae
