All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention discloses a distributed pier anti-collision device, which comprises a composite material anti-collision system 2 arranged along the periphery of a pier 1, wherein the composite material anti-collision system 2 consists of a plurality of composite material anti-collision sections 205, and all the composite material anti-collision sections 205 form a ring shape with the cross section concentric with the pier. Electromagnetic units 3 are arranged at two ends of the composite material anti-collision section 205 to generate repulsive force, so that collision abrasion between the composite material anti-collision sections 205 is reduced. The rubber anti-collision pad 4 is fixed on the outer side of the electromagnetic unit 3 by adopting rubber adhesive, so that the electromagnetic unit 3 and the composite anti-collision section 205 can be effectively protected.
The composite impact segment 205 includes a composite facing 201, a composite web 202, a foam core 203, and a particulate filler 204. The composite anti-collision section 205 is manufactured by a vacuum introduction integrated molding process, before molding, a filling hole 206 is reserved on the top surface of the composite anti-collision section 205, and then the granular filling 204 is injected through the reserved filling hole 206. The composite anti-collision segment 205 has simple manufacturing process, convenient transportation and installation, and convenient maintenance after damage.
As shown in fig. 4-6, the composite collision avoidance system 2 is flexibly connected with the pier 1 through the traction sliding system 5, and the traction sliding system 5 is symmetrically arranged along the circumferential direction of the composite collision avoidance section 205. The traction sliding system 5 comprises a composite pull ring 501 fixed to a reserved groove 207 on the inner side of the composite anti-collision section 205, a composite sliding groove 504 fixedly connected vertically along the pier 1, a composite sliding block 502 embedded in the composite sliding groove 504, and a composite lock chain 503 connecting the composite pull ring 501 and the composite sliding block 502. The traction sliding system 5 enables the dispersed composite material anti-collision sections 205 to always surround the periphery of the bridge pier 1, and the composite material anti-collision sections 205 float on the water surface through the light materials and structures of the composite material anti-collision sections 205, so that vertical free floating is realized. Besides the traction sliding system 5, rubber fenders 6 distributed in an array are fastened around the bridge pier 1 through bolts, so that the collision avoidance device is prevented from directly colliding with the bridge pier, and damage to the bridge is effectively reduced.
Preferably, the rubber anti-collision pad 4 and the rubber fender 6 adopt natural rubber, chloroprene rubber or polyurethane rubber, and the rubber adhesive is a natural rubber adhesive, a chloroprene rubber adhesive or a polyurethane rubber adhesive; the composite material surface layer 201, the composite material web 202, the composite material pull ring 501, the composite material slide block 502, the composite material lock chain 503, the composite material slide groove 504, the composite material support main beam 702 and the composite material support secondary beam 703 adopt glass fiber, aramid fiber, carbon fiber or basalt fiber, and the matrix material is unsaturated polyester resin, epoxy resin, phenolic resin or vinyl ester resin; the foam core 203 is made of polyurethane, polyethylene or polyvinyl chloride; the particulate filler 204 is a ceramic granule, rice hull, rubber granule or hollow sphere.
As shown in fig. 7-9, the invention further comprises a solar power generation system 7 which is fixed on the upper part of the bridge pier 1, and is also arranged above the water surface on the upper parts of the composite material anti-collision system 2 and the traction sliding system 5. The solar power generation system 7 includes a solar power generation panel 701, a composite support main beam 702, and a composite support secondary beam 703, the composite support main beam 702, and the composite support secondary beam 703 being configured to support the solar power generation panel 701. The composite material bracket main beam 702 and the composite material bracket secondary beam 703 are fastened around the bridge pier 1 through bolts, and the composite material bracket main beam 702 is slightly longer than the composite material bracket secondary beam 703. The solar power generation system 7 stably supplies power to the electromagnetic unit 3 for a long time through renewable solar energy.
Preferably, the solar power generation plate 701 is a curved plate or a flat plate, and the composite support main beam 702 and the composite support secondary beam 703 are solid or hollow, and have a circular or square cross-sectional shape.
In the implementation process of the invention, when the anti-collision device is collided by a ship, the impact force is reduced by bending deformation of the composite material surface layer 201 and the composite material web 202 and compression buffering and energy absorption of the foam core material 203. When the deformation is large, the internal particulate filler 204 is broken by friction and dissipates energy. However, at this time, since the electromagnetic unit 3 generates a repulsive force, collision and abrasion do not occur between the composite anti-collision sections 205, and the rubber anti-collision pad 4 outside the electromagnetic unit 3 can also effectively protect the electromagnetic unit 3 and the composite anti-collision sections 205.
Preferably, the unit cross-sectional shape of the composite web 202 is rectangular, trapezoidal or honeycomb, and the number of layers of the composite web 202 is single-layer, double-layer or multi-layer. If the composite web 202 is double or multi-layered, the arrangement is orthogonal or offset. The arrangement of the multi-layer composite web 202 in combination with the internal particulate filler 204 can provide sufficient resistance against the ship's impact load, while the design of the dislocated composite web 202 can prevent the impact contact stiffness from being too great, thereby achieving the effect of reducing the impact load.
Meanwhile, in the service process, the wave action can cause the anti-collision device to repeatedly move in a fluctuating way, and the scattered segmental design can effectively avoid the fracture and damage of the anti-collision device due to overlarge wavelength and wave height.
