Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the Anti-scouring device of a kind of offshore wind turbine single-pile foundation provided by the utility model, including gear
Plate, silk ribbon curtain 1, connecting plate and ballast 2；Baffle is divided into outer layer baffle 3 and internal layer baffle 4；Baffle is strip, cross section
In " [" type, outwardly, outer layer baffle 3 and internal layer baffle 4 are formed and handed over along being alternately arranged successively around single pile 11 two turn ends
The inside and outside double-layer structure replaced is connected between adjacent outer layer baffle 3 and internal layer baffle 4 by silk ribbon curtain 1；Outer layer baffle 3 is
Prevent first barrier of the soil around pile by seawater scouring, the effect of internal layer baffle 4 is similar with outer layer baffle 3, passes through friendship inside and outside two layers
Wrong arrangement increases the flow path of stake surrounding seawater, and to slow down water body flow speed, silk ribbon curtain 1 is hindered using increase
The mode of power and the speed for slowing down water body flow；The upper and lower ends of baffle be installed with respectively strap bolt mouth 5 upper junction plate 6, under
Connecting plate 7；The upper and lower ends of silk ribbon curtain 2 are separately installed with the upper junction plate 6 of strap bolt mouth 5, lower connecting plate 7；Connecting plate and
Baffle is all made of burn into intensity height, cheap polypropylene plastics；Between adjacent outer layer baffle 3 and silk ribbon curtain 1, with
And it between adjacent silk ribbon curtain 1 and internal layer baffle 4, is attached by the bolt of the bolt mouth 5 on connecting plate；Phase
Spacing between two pieces of adjacent outer layer baffles 3 is shorter than the width of outer layer baffle 3, the spacing between adjacent two pieces of internal layer baffles 4
The shorter than width of internal layer baffle 4；Ballast 2 carries out the connection that lower end is arranged in after force analysis according to the concrete condition of engineering
On plate.The ballast 2 wraps up sand, cement or the larger material of other density with geotextile and is formed, and prevents total
Float or impacted when flow velocity improves and disintegrated, counterweight appropriate and pendulum are selected according to the long-term ocean current rule of engineering local environment
Put mode.Offshore wind turbine single-pile foundation protective device can be increased according to the actual demand of engineering the number of turns or the other materials of selection or
The baffle of size.
As shown in Fig. 3, Fig. 5 (a), silk ribbon curtain 1 is made of several floating bands 8, and floating band 8 is prepared by polypropylene plastics
Faciola, cross section are rectangle；Several rectangular notches 10 in blossom type distribution, floating are provided on the connecting plate of silk ribbon curtain 1
It is clamped on two pieces of connecting plates up and down by rectangular notch 10 respectively with 8 both ends, floating band 8 is slightly longer, not tight so that seawater
Band 8 is floated when flowing to wave.
As shown in Fig. 4, Fig. 5 (b), be provided on the connecting plate of baffle " [" type groove mouth 9, baffle pass through " [" type groove mouth 9 block
Tightly on connecting plate.
When the offshore wind turbine single-pile foundation protective device works, a part of flow front flow to 3 front of outer layer baffle, and
3 bending segment of outer layer baffle can effectively shut off, and the current scour of this part is prevented to take away the soil body；The flow of another part passes through outer layer
Opening between baffle 3 strikes internal layer baffle 4, and bending end equally plays the effect for deceleration of shutting off, and flow expands to both sides
It dissipates, when by silk ribbon curtain 1 to both sides, floating band 8 generates flow certain resistance, passes through swing and absorbs energy so that
Flow continues to slow down.By the drag effect for increasing flow path and silk ribbon curtain 1 of ectonexine baffle, flow reaches most
Speed has fallen to permissible velocity hereinafter, local scour will not be caused to act on single pile when the single pile surface of internal layer, baffle and silk
Upper and lower side with curtain 1 is all greatly improved with connecting plate by the reinforcings such as bolt, notch, globality and durability, Neng Gouchang
It is effectively guaranteed the security and stability of pile body bearing capacity long.
