Sinkable floating alga ecological restoration device

Abstract

The invention discloses a sinkable floating alga ecological restoration device which can purify water, supplement alga population through sporophyte diffusion during macroalga reproduction and achievea wind and wave preventing function through manual sinking. The sinkable floating alga ecological restoration device comprises a base, a support floating rack, an alga culture device and a connectionand sinking triggering mechanism and is characterized in that the support floating rack is connected with the base through first connecting ropes; the alga culture device comprises a floating platform floating below the support floating rack, an alga rack arranged on the floating platform and pre-connection ropes connecting the alga rack and the support floating rack; the connection and sinking triggering mechanism comprises a slide sleeve slidably arranged in a vertical guide sleeve, a lower connector arranged in the slide sleeve, a triggering rope connecting a floating ball and an upper piston, a second connecting rope connecting a bottom touch release mechanism and a lower connector and a third connecting rope connecting a counterweight and the base.

Description

technical field [0001] The invention relates to a seaweed cultivation device, in particular to a sinkable suspended seaweed ecological restoration device. Background technique [0002] Affected by changes in the near-shore marine environment, the transparency of seawater has decreased, the sediments on the attachment base of near-shore rock reefs have increased, the habitat of large seaweeds has been covered by a large number of low coral algae that can adapt to environmental changes, and the near-shore rock reefs have a large slope. As a result, the space suitable for macroalgae habitat gradually shrinks. [0003] In order to expand the restoration area of ​​algae farms, placing artificial algae reefs has become one of the most common methods at present. The current artificial algae reefs are roughly divided into two categories: one is sunken algae reefs, which have very high requirements for the transparency of seawater in sea areas, otherwise it is difficult for seaweeds...

AI Technical Summary

Problems solved by technology

The current artificial algae reefs are roughly divided into two categories: one is sunken algae reefs, which have very high requirements for the transparency of seawater in sea areas, otherwise it is difficult for seaweeds to obtain suitable light conditions; and they are easily covered by sediments; 2. Floating algae reefs (floating on the sea surface by floating balls, suspending the algae reefs in the sea water), this type of floating algae reefs are not only greatly affected by the waves of the sea surface, but also easily damaged by the floating of the sea surface waves. Seaweed growing on the reef; and floating balls floating on the sea will also block sunlight and affect the light conditions of seaweed

This makes the current artificial seaweed reefs unsuitable for artificial placement and transplantation of seaweed in many areas
