The river levee is impacted by river water in the use process of the river levee in the years, and particularly the river levee is easily damaged when the river surface is influenced by severe weather to generate large water waves. Based on this, it is proposed in the prior art to provide a protective structure on the river levee to reduce the damage of river water to the river levee, and the protective structure in the prior art usually includes a protective plate capable of deflecting, and when the protective plate is impacted by water waves, a certain deflection occurs along the situation to facilitate energy dissipation.

One end (upper end or lower end) of a protection plate in the prior art is generally hinged on a river bank, the other end of the protection plate inclines to the direction far away from the river bank, and when the protection plate is impacted by water waves, the free end of the protection plate deflects to the direction of the river bank. When the upper end of the protection plate is hinged to the river bank, for higher water waves to impact the upper part of the protection plate, the deflection angle of the upper part of the protection plate is smaller due to stress, so that the upper part of the protection plate is easy to damage due to larger impact force; when the guard plate lower extreme articulates on the river levee, for making the guard plate can bear higher unrestrained, the guard plate upper end need set up higher, and unrestrained still crosses the guard plate upper end easily, leads to the cushioning effect of guard plate not enough ideal, simultaneously, after the guard plate was crossed to the filth of unrestrained motion, will remain between guard plate and the river levee, especially lies in the guard plate lower part behind the sediment setting, influences the deflection of guard plate easily.

Compared with the prior art, the invention has the following beneficial effects: 1. daily river surface rivers are comparatively gentle, and the buffer board receives the rivers effort, the reciprocating swing of small-amplitude. And receive the influence of rocking of buffer board, certain shock also can take place for rivers between buffer board and the guard plate, and the rivers of being more convenient for drive the floater motion, collect the floater of water level through the suction in the collecting vessel. Meanwhile, the buffer plate is shaken slightly, so that the dirt is prevented from being adhered to the buffer plate to a certain extent.

2. When the water wave is large, the water wave pushes the buffer plate to deflect towards the direction close to the protection plate, partial kinetic energy of the water wave is converted into the kinetic energy of the deflection of the buffer plate, the water wave cannot directly impact on the protection plate, and the river bank is protected to a certain extent.

And when the buffer board takes place to deflect by a wide margin, the one end that the rope was connected on the buffer board to the second risees the position along with the deflection of buffer board gradually, and then make the slope direction of second connection rope change, then the slope of rope is connected along with the second to the salvage fork that is located the second connection rope, drive the floater on the surface of water to being close to the motion of guard plate direction, make the floater be close to the collecting vessel, and then be more convenient for be collected by the collecting vessel, especially the filth that carries when the unrestrained is great is also more, and take away the filth again when avoiding unrestrained, consequently, the fork is salvaged in the design and the collecting vessel of being convenient for is collected.
