Mixed reef body

Abstract

The invention discloses a mixed reef body which comprises a floater, two supporting frames and a balancing weight. The floater, the supporting frames and the balancing weight are connected in sequence through a pulling rope. The two supporting frames are connected in series in the vertical direction. Each supporting frame comprises a center rod, a sliding sleeve and a plurality of sector supporting plates, wherein the sliding sleeve is in sliding connection with the center rod, and the sector supporting plates are arranged in the circumferential direction of the center rod, a plurality of alga cultivation bricks are arranged on each sector supporting plate, a connecting base is arranged on the top of the center rod, the sector supporting plates are rotationally connected with the connecting base in the vertical face, a supporting rod is hinged between the sliding sleeve and the lower surface of each sector supporting plate, the sliding sleeve is connected with the connecting base through a tension spring, the corresponding side edges of every two adjacent sector supporting plates are tightly attached to each other when the sliding sleeve is in the sliding stroke top dead center. An air exhaust valve is arranged on the floater. According to the mixed reef body, apposition growth of alga seedlings is facilitated, alga seedlings in the initial growth stage are well protected, the alga survival rate is improved, and meanwhile concentrated putting-in and management are convenient.

Description

technical field [0001] The invention relates to the field of marine algae cultivation, in particular to a mixed reef body. Background technique [0002] Macroalgae grow in the intertidal subtidal zone and subtidal shallow water zone of the mid- and high-latitude seas. As supporting plants, other plankton, swimming animals, benthic animals, and environmental factors that coexist with them constitute the nearshore ecosystem. . Seaweed farms supported by macroalgae have high primary productivity, and at the same time form a complex animal and plant food web that can enrich eutrophic salts such as N and P, restrain the outbreak of "red tide" and protect the marine environment. The economic value created by seaweed farms is great. Seaweed itself has industrial, edible and medical value. Seaweed farms also provide places for fish to seek bait, avoid enemies, and lay eggs. However, according to recent observations, seaweed fields are disappearing, and seaweed biodiversity is decl...
