Method for achieving blue-green algae prevention and control and ship passing of lake-entering river channel through flexible enclosure

Abstract

The invention provides a method for achieving blue-green algae prevention and control and ship passing of a lake-entering river channel through a flexible enclosure, and relates to the technical field of blue-green algae prevention and control. Sliding rails are vertically arranged on river walls on the two sides correspondingly, pulleys are arranged in the sliding rails and can slide up and down along the sliding rails, connecting pieces of the pulleys are fixed to one ends of the pulleys, and the other ends of the pulleys are connected with the enclosure; the enclosure is composed of two sections, and the two sections of the enclosure are movably connected through the connecting pieces; each connecting piece is composed of a first connecting plate and a second connecting plate, and the first connecting plates and the second connecting plates which are horizontally arranged are connected through movable mechanisms; when algae need to be controlled, the movable connecting relation of the two sections of the enclosure is kept; and when navigation is needed, the movable connecting relation of the connecting pieces of the two sections of the enclosure is relieved, one side of the enclosure with the movable connecting relation relieved is hung on the upper portion of the river wall which is still connected with the other side of the enclosure, the enclosure is opened, and the lake surface is vacated for navigation. According to the method, the flexible enclosure can be used according to the interception requirement, and conversion between blue-green algae prevention and control and ship free passing can be completed conveniently in time.

Description

technical field [0001] The invention relates to the technical field of cyanobacteria prevention and control, in particular, according to interception requirements, the use of flexible enclosures can timely and conveniently complete the conversion between cyanobacteria prevention and control and free passage of ships. Background technique [0002] The influx of blue-green algae and the large-scale accumulation and whitening of blue-green algae occurred in the river channel entering the lake, which seriously affected the water quality of the river channel and the image of the regional water environment. In order to prevent the impact of blue-green algae on the water quality and water ecological environment of the river, and to enhance and improve the image of the regional water environment, enclosures are usually used to prevent and control blue-green algae. The enclosures are fixed in the water body through anchor piles and cable systems. After the construction is completed, t...

Problems solved by technology

In order to prevent the impact of blue-green algae on the water quality and water ecological environment of the river, and to enhance and improve the image of the regional water environment, enclosures are usually used to prevent and control blue-green algae. The enclosures are fixed in the water body through anchor piles and cable systems. After the construction is completed, the enclosures It is a fixed connection and cannot be disconnected in the middle. In addition to the need to prevent and control blue-green algae, the rivers entering the lake also need to be navigable at any time. To be navigable, the enclosure needs to be removed. The current enclosure cannot be used without dismantling. It is a good solution to the different requirements of intercepting cyanobacteria and navigation
