[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0025] Example: Figure 1 As shown, the anti-collision protection device for the pier column of this embodiment includes an annular fixed fence 1, an annular movable fence 2 and a buffer anti-collision structure 3. The fixed fence 1 is fixedly arranged around the lower end of the pier column, the movable fence 2 is arranged outside the fixed fence 1 and is connected to the fixed fence 1 for vertical sliding. The buffer anti-collision structure 3 is arranged on the outer periphery of the movable fence 2, and a float 4 is installed at the lower end of the movable fence 2.
[0026] In the anti-collision protection device for the bridge pier column of this embodiment, the fixed fence 1 is composed of a plurality of first fence units connected end to end in a ring direction, and each first fence unit is anchored to the surface of the bridge pier column by bolts. The movable fence 2 is also composed of a plurality of second fence units connected end to end in a ring direction, and each second fence unit is anchored to the surface of the bridge pier column by bolts. The movable fence 2 is connected to the fixed fence 1 by sliding up and down, and a float 4 is installed at the lower end of the movable fence 2. When in use, the buoyancy of the float 4 in the water enables the movable fence 2 to move up and down relative to the fixed fence 1 as the water level rises or falls (the lifting height of the movable fence 2 is designed to be within the safe height, and generally it will not be separated from the fixed fence 1 under normal water level). The buffer anti-collision structure 3 on the periphery of the movable fence 2 can fully buffer and absorb energy when a ship collides with it, and has a better anti-collision protection effect.
[0027] As a preferred embodiment, the buffer and anti-collision structure 3 includes a fixed plate 31, an elastically bendable anti-collision force unloading plate 32 and an elastic force unloading filling piece 33. The fixed plate 31 is detachably fixed to the lower end of the outer periphery of the movable fence 2. The anti-collision force unloading plate 32 is integrally connected to the outer side of the lower end of the fixed plate 31, and can be deformed and bent toward the side of the fixed plate 31 after being hit by an external force, or return to its position after the external force is removed. The elastic force unloading filling piece 33 is arranged between the inner side of the anti-collision force unloading plate 32 and the movable fence 2.
[0028] In the above embodiment, the fixed plate 31 is fixed to the movable fence 2 in a detachable manner, and can be removed and replaced after the buffering and anti-collision structure 3 is damaged. The outer surface contour of the anti-collision unloading plate 32 is an arc shape, which can be deformed inward after a collision, achieving a good unloading effect. At the same time, with the extrusion deformation of the elastic unloading filling member 33 filled inside, the double combination will achieve a very good collision unloading and buffering purpose.
[0029] As a preferred embodiment, the longitudinal section of the anti-collision force-draining plate 32 is arc-shaped, and an escape portion 321 bent toward the movable fence 2 is provided at its upper end.
[0030] In the above embodiment, the upper end of the anti-collision force-draining plate 32 is bent inwardly without any sharp edge, so when a collision with a ship occurs, the damage after the contact can be reduced.
[0031] As a preferred embodiment, Figure 2 As shown, a flexible barrier net 5 is connected between the upper end of the anti-collision force-removing plate 32 and the upper end of the movable fence 2 .
[0032] In the above embodiment, the barrier net 5 is a flexible component, which will not suppress the deformation of the anti-collision force unloading plate 32 when a collision occurs, and can shield and protect the upper part of the cavity between the upper end of the anti-collision force unloading plate 32 and the movable fence 2 to prevent the accumulation of impurities inside or the entry of other organisms.
[0033] In this embodiment, the elastic force-removing filling member 33 is a rubber member or an air bag, which has good deformation and elastic recovery performance and can achieve a good buffering and force-removing effect.
[0034] As a preferred embodiment, a flexible energy-absorbing cushion layer is provided on the surface of the anti-collision force-removing plate 32, and a reflective mark is provided on the surface of the energy-absorbing cushion layer.
[0035] In the above embodiment, the energy absorbing cushion layer can protect the anti-collision force unloading plate 32 to a certain extent. The external reflective mark can also remind passing ships and reduce collisions.
[0036] As a preferred embodiment, the outer surface of the fixed fence 1 is provided with a plurality of vertically extending rails 11 at intervals along its circumferential direction, and the inner side of the movable fence 2 is provided with a plurality of vertically extending limit grooves 21 corresponding to the rails 11 one by one, and the rails 11 extend into the limit grooves 21.
[0037] In the above implementation scheme, the structural design of the track 11 and the limiting groove 21 can ensure good up-and-down sliding cooperation performance between the movable fence 2 and the fixed fence 1 .
[0038] In this embodiment, an annular mounting plate 22 is provided at the lower end of the movable fence 2, and the floating body 4 is provided at the lower end of the mounting plate 22. The design of the mounting plate 22 facilitates the assembly of the floating body 4 and facilitates the stable installation of the floating body 4 as a whole.
[0039] In this embodiment, the floating body 4 includes a plurality of floating boxes, and the plurality of floating boxes are evenly spaced and installed at the lower end of the mounting plate 22 .
[0040] As a preferred embodiment, Figure 3 As shown, a bird repeller 6 is installed at the upper end of the fixed fence 1 through a column.
[0041] In the above implementation scheme, the bird repeller 6 adopts a conventional product on the market. Photovoltaics can be set on the side guardrails of the bridge deck to power the bird repeller 6. The design of the bird repeller 6 can drive away the docked birds and prevent the birds from building nests here and affecting the normal floating of the movable fence 2.
