Blue-green algae collecting floating dam enclosure device

Abstract

The invention discloses a blue-green algae collecting floating dam enclosure device. The blue-green algae collecting floating dam enclosure device comprises two buoys, wherein the two buoys are formed by connecting a plurality of sections of HDPE hollow winding pipes through flanges; a gap is reserved between the two buoys, and the two buoys are arranged in parallel; the outermost two end surfaces of the two buoys are blocked through sealing sleeves; a first group of connecting pieces and a second group of connecting pieces are arranged at symmetrical positions of the inner sides of the two buoys; a walkway plate is laid on the upper parts of the two buoys through the first group of connecting pieces; a fixing frame is mounted on the lower parts of the two buoys through the second group of connecting pieces; the two buoys are connected into a whole through the walkway plate and the fixing frame; wave-proof algae-blocking balancing devices facing the windward side of lake water are arranged on one side or two sides of the tops of the two buoys; an algae-proof curtain is hung at the bottoms of the two buoys in a falling manner; and a counterweight chain is arranged at the lower end of the algae-proof curtain. The blue-green algae collecting floating dam enclosure device can resist wind wave scouring and solar ultraviolet illumination, is durable, efficiently blocks blue-green algae from flowing into the bank, and facilitates salvage of operators.

Description

technical field [0001] The invention relates to the technical field of cyanobacteria control, in particular to a floating dam enclosure device for collecting cyanobacteria. Background technique [0002] With the development of industrial society, the discharged water contains excessive nutrients such as nitrogen and phosphorus, which will easily cause eutrophication in the lake water, which will cause a large number of cyanobacteria to multiply in summer. During the process of cyanobacteria decomposition, a large amount of dissolved oxygen in the water will be consumed. , leading to serious pollution of the water body, followed by blackening and smelling. [0003] At present, the main solution to deal with large-scale cyanobacteria blooming to the lake is to set up enclosures on the lake shore to block the cyanobacteria blooms on the lake shore before further salvage and disposal; the enclosure material is mainly PVC double-sided coating Covered with plastic cloth, the floa...

Problems solved by technology

At the same time, due to the strong wind and waves in the lake, the enclosure is continuously washed away, and the ultraviolet rays in the sun will also aggravate the aging of the enclosure surface, requiring operators to maintain, repair and replace the enclosure frequently

[0004] The enclosure materials currently on the market can no longer meet the technical development requirements in the field of cyanobacteria management. Therefore, there is an urgent need for a floating dam enclosure device that is resistant to wind and wave erosion, anti-ultraviolet light from the sun, durable, and efficiently intercepts cyanobacteria.
