Self-deformation available type combined ecological floating bed not hindering river flood discharge

Abstract

The invention discloses a self-deformation available type combined ecological floating bed not hindering river flood discharge, which belongs to the field of water environment protection and is suitable for water quality purification and environmental protection of rivers with flood discharge functions. The self-deformation available type combined ecological floating bed is characterized in that the floating bed body is composed of a central floating bed block and an even number of flank floating bed blocks, the floating bed blocks form free hinge connection by lateral slide bars and sliding rings, and the floating bed blocks can be relatively moved and rotated. The combined floating bed is hooked on a front fixing frame and a rear fixing rod, the appearance of the combined floating bed is a rectangle under low water level conditions during drought period and normal water period, and is consistent with that of a common floating bed. When the water level is close to the warning water level of a river in wet season, the flank floating bed blocks are deviated from the front fixing frame, and the combined floating bed automatically unfolds to deform to a cone, so as to reduce the inhibition on the water flow. After the invention is implemented, the risk of the ecological floating bed hindering the river flood discharge can be effectively reduced, and the application range of the ecological floating bed in various rivers is expanded.

Description

technical field [0001] The invention relates to a device for purifying the water quality of polluted rivers, in particular to a self-deformable combined ecological floating bed which does not hinder river flooding, and belongs to the field of water environment protection. Background technique [0002] With the improvement of the degree of industrialization and the increase of local population density, human beings discharge more and more sewage and waste water to the surrounding water bodies, causing a large number of rivers and lakes to be polluted to varying degrees, seriously threatening the regional ecological environment and people's well-being. Physical health also restricts the sustainable development of social economy. At present, a variety of water pollution control and restoration methods have been applied to the treatment of water eutrophication. Among them, artificial ecological floating bed is a typical surface water ecological restoration technology. This meth...

But at the same time, due to the fixed shape of this type of rectangular floating bed, the water resistance is serious under large water flow, and the bed body of the floating bed is mostly a solid sealing member, which has poor wave dissipation performance, and the impact of the water flow can easily cause damage to the floating bed

Therefore, the use of this type of ecological floating bed is often restricted in flood channels. Even if it is used, the floating bed must be temporarily dismantled or reinforced before the flood season, and then reassembled after the flood season, which wastes a lot of manpower and material resources, and greatly limits Application range of ecological floating bed
