a breathing algal reef

Abstract

The invention discloses a breathable algal reef and aims to provide an algal reef capable of effectively clearing away sediments on the surface of the algal reef and avoiding the effect of the sediments on algae adhesion and growth. The breathable algal reef comprises a floating ball, a connecting rope, a conical algal reef body, a guide hole and a piston body, wherein the guide hole is formed in the middle of the algal reef body and penetrates through the top surface and the bottom surface of the algal reef body; the piston body is arranged in the guide hole in a sliding way; a lower limiting convex block is arranged in the guide hole below the piston body; an upper baffle is arranged above an upper opening of the guide hole and is fixedly arranged on the algal reef body; a circle of annular flow guide plates extending obliquely and downwardly towards the outer side of the upper baffle is arranged on the edge of the upper baffle; a pre-tightened compression spring is arranged in the guide hole between the piston body and the upper baffle; a rope through hole is formed in the middle of the upper baffle; a plurality of supporting blocks for supporting the algal reef body are arranged on the bottom surface of the algal reef body; one end of the connecting rope is connected with the floating ball, and the other end of the connecting rope penetrates through the rope through hole and is connected with the piston body.

Description

technical field [0001] The invention relates to the field of artificial algae reefs, in particular to a breathable algae reef. 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 obtain suitable light c...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the artificial algal reef has the sediment on the surface of the algal reef, which is difficult to effectively remove after it gathers, resulting in the difficulty of attaching and growing the algae sporophyte. The sediment has an impact on the attachment and growth of algae; it can also stir the sediment on the seabed, make the nutrients deposited on the seabed diffuse and rise, improve the primary productivity of the sea area near the artificial algae reef, and provide sufficient bait for fish. Good fish gathering effect is conducive to the formation of a more complete marine ecosystem with breathable algae reefs
