Liftable cyanobacteria prevention and control floating dam

Abstract

The invention discloses a liftable cyanobacteria prevention and control floating dam. The liftable cyanobacteria prevention and control floating dam comprises a flexible tube, wherein a balance weight is arranged below the flexible tube; a location mechanism is arranged between the flexible tube and a water bottom; and a gas inflation port and a gas inflation valve are arranged on the flexible tube. The liftable cyanobacteria prevention and control floating dam is characterized by further comprising an isolation screen used for isolating the cyanobacteria, wherein the length of the isolation screen is adaptive to the length of the flexible tube, and the upper side of the isolation screen is connected together with one longitudinal side of the flexible tube. The balance weight is connected at the lower side of the isolation screen. A gas deflation port and a gas deflation valve are arranged on the flexible tube. The cyanobacteria prevention and control floating dam is high in intercept and guide efficiency for the cyanobacteria, long in service life, free from influence on an ecological landscape, and capable of ensuring normal use thereof. The liftable cyanobacteria prevention and control floating dam disclosed by the invention can be used in a eutrophicated water body which is liable to cause 'water bloom' outbreak of the cyanobacteria for isolating the cyanobacteria. The liftable cyanobacteria prevention and control floating dam is suitable for water bodies such as rivers, lakes, reservoirs and ponds.

Description

technical field [0001] The invention relates to a cyanobacteria isolation zone. Specifically, it is a liftable cyanobacteria prevention and control floating dam used to isolate cyanobacteria in eutrophic water bodies prone to cyanobacteria "bloom" outbreaks. Suitable for water bodies such as rivers, lakes, reservoirs and ponds. Background technique [0002] In recent years, due to changes in the ecological environment, some water bodies such as rivers, lakes, reservoirs, and ponds have gradually become eutrophic. Whenever summer comes, these eutrophic water bodies often have cyanobacteria "blooms". Once a cyanobacteria "bloom" breaks out, in order to ensure that the water body is not polluted, it is necessary to collect and treat the cyanobacteria in the water body. At present, the method of collecting blue-green algae in the water body mainly adopts the setting of blue-green algae prevention and control floating dams on the water surface along the water body. The cyanoba...

Problems solved by technology

Since this cyanobacteria prevention and control floating dam is only connected by multiple floating bodies, it can only float on the water surface, and can only intercept and guide the cyanobacteria on the water surface, but cannot intercept and guide the tiny cyanobacteria below the water surface. The interception and guidance efficiency is not high

And because this cyanobacteria prevention and control floating dam is only connected by a plurality of floating bodies, it floats on the water surface all the year round and cannot sink below the water surface.

Since this kind of cyanobacteria control floating dam floats on the water surface all the year round, it cannot sink below the water surface in winter and spring when the cyanobacteria are not blooming, which will have an impact on the ecological landscape

In addition, there is only one air port on the floating body. Once a floating body is damaged and air leakage occurs during inflation, the gas will leak out through the damaged part of the floating body, thereby affecting the inflation of other floating bodies. Therefore, it is difficult to ensure The normal use of the entire cyanobacteria control floating dam
