Embodiment 1

[0032] Such as figure 1 , 2 shown.

[0033] A composite material bridge anti-collision device, which can be in the form of a strip structure for installation on a pier, or in a ring structure matching the shape of the bridge, and the strip or ring structure has at least one figure 1 The shown anti-collision unit 10 is composed of two adjacent and mutually connected anti-collision units 10 connected by flanges 4 and bolts 5, as figure 2 (b) and figure 2 As shown in (a), the anti-collision unit 10 is composed of a shell 11 and a filling material 3 filled in the shell 11. The shell 11 is a solid shell of composite material or is made of two layers of composite material inside and outside. The structure composed of layer 1 and sandwich material 2. The cushioning material 6 is a rubber tire, rubber granules, rubber block or polyurethane elastomer during specific implementation. The sandwich material 2 is paulownia wood, balsa wood, polyurethane foam, PVC foam, PEI foam, PMI ...

Embodiment 2

[0035] Such as image 3 , 4 , 5 shown.

[0036] A composite material bridge anti-collision device, it is a strip or ring structure matching the shape of the bridge, the strip or ring structure has at least one anti-collision unit 10 and connecting rod 12 (such as Figure 4 (b) shows) composition, two adjacent and interconnected anti-collision units 10 can be connected by flange 4 and bolt 5 ( Figure 4The integral structure is adopted, so there is no need for flanges and bolts 5, when the perimeter of the anti-collision unit is long, it is best to use the flange and bolt connection structure to connect the anti-collision units into a whole), the connecting rod 12 It is installed at both ends of an anti-collision unit 10 or between two adjacent but not connected anti-collision units 10 to form a ring structure; the anti-collision unit 10 is either composed of a shell 11 and filled in the shell The filling material 3 in the body 11 and the canvas bag 7 filled with the buffer ...

example 1

[0048] In the composite material bridge anti-collision device of the present invention, the shell is a composite material surface layer 1 formed by curing glass fiber and vinyl resin, and adopts Paulownia wood core material 2 to form a composite material sandwich structure shell, and the cross section of the shell is semicircular D-shaped. Prepared by vacuum introduction process, using flanges and bolts 4 to combine the D-shaped shell and the flat shell to form a closed composite shell; the interior of the composite shell is filled with moso bamboo 3 arranged horizontally; the unit segments of the anti-collision system are surrounded by rectangular cross-section piers , using flanges and bolts 5 to form a whole circular composite anti-collision system; thin rubber blocks are set at the four corners of the rectangular cross-section pier to reduce the impact of the anti-collision ring and the pier under the action of water flow. Such as Figure 4 .

Abstract

The invention relates to a bridge anti-collision device of a composite material, which is characterized in that the bridge anti-collision device of the composite material is in a bar-shaped structure or an annular structure which is matched with the shape of a bridge, wherein the bar-shaped or annular structure is at least provided with an anti-collision unit (10) or at least comprises one anti-collision unit (10) and one connecting rod (12). The two adjacent anti-collision units (10) which are mutually connected are connected by a flange (4) and a bolt (5), and the connecting rods (12) are installed at both ends of one anti-collision unit (10) or are installed between the two anti-collision units (10) which are adjacent but not connected with each other so as to form the annular structure; each anti-collision unit (10) comprises a casing (11), a filling material (3) filled in the casing (11) and a canvas bag (7) which is installed at one side of the casing and is filled with a buffering material (6), the canvas bags (7) are connected with the casings (11) by pull ropes (8), anti-collision handrails (9) are also connected on the casings (11), and the casings (11) are also solid casings of the composite material or are in a structure comprising two layers of internal and external composite material surface layers (1) and a sandwich material (2). The invention has low cost, good anti-collision performance, greenness and environmental protection.

Description

[0001] The invention applied for a utility model patent on the same day. technical field [0002] The invention relates to a bridge or wharf anti-collision structure, in particular to a low-cost green anti-collision device made of composite materials, in particular to a pier suitable for various types of bridges and wharves, water (ocean) buildings lightening Composite material bridge anti-collision device for ship (floe ice) impact disaster. Background technique [0003] As we all know, ship collision accidents have been happening all over the world, and the frequency of ship collision accidents is much higher than we imagined. The loss of life, property damage, and environmental damage caused by ship-bridge accidents is staggering. Many ship collision accidents range from losses of tens of thousands of yuan to casualties, losses in millions, tens of millions or even billions of dollars, and a large number of indirect losses are even more difficult to calculate. Therefore...
