In non-flood period, as shown in figure 3, river level 9 is relatively low, floating bed matrix 8 drives rope 2 that protective plate 1 is lifted and exposed
The water surface.Now water velocity is slower, and current will not produce impact failure to root system of plant 14 and its biomembrane on surface, while compared with
Small water velocity can strengthen the area of root system 14 and the mass exchange of extraneous water body, so as to improve the purification of water quality efficiency of floating bed.
In flood season, as shown in Fig. 2 the rapid increase of river level 9, floating bed matrix 8 also lifting and drives rope 2 to make therewith
Protective plate 1 is obtained to drop to below the water surface.Because now water velocity is larger, protective plate 1 is located at the front portion in the region of root system 14, can have
What is imitated prevents root system 14 and its biomembrane of surface attachment by high flow velocity water body impact failure, while the protective plate 1 of arc also may be used
Shunting action is played to current, so as to reduce resistance of the flood season floating bed to river course flood.After flood season terminates, river level is gradually
Decline, floating bed matrix 8 drives rope 2 gradually to lift protective plate 1 until being completely exposed the water surface again.
Swing fixation is carried out to floating bed matrix 8 using front and rear double-rod in the present invention, front portion is rotated using preceding fix bar 5
Spacing, it is spacing that rear portion carries out the amplitude of oscillation using nylon rope 12 so that floating bed body can meet stream in mass-flow and swing, and is conducive to improving water
The percent of pass of stream, and protect floating bed structure not sensitive for damages.
