Description

A bridge collision avoidance device based on tidal energy and magnetic levitation repulsion. Technical Field

[0001] This invention relates to the field of bridge protection technology, and in particular to a lightweight bridge anti-collision device based on tidal energy and magnetic levitation repulsion, suitable for variable cross-sections. Background Technology

[0002] With economic development and the deepening of globalization, the construction and expansion of transportation networks have become crucial. Bridges, as key nodes in these networks, bear the ever-increasing traffic flow, and their safety and reliability are directly related to people's lives and property, as well as national economic development. However, with the booming development of the shipping industry and the continuous advancement of ship technology, the problem of ships colliding with bridge piers has become increasingly prominent, posing a significant challenge to the safe operation of bridges, causing huge economic losses, and endangering lives.

[0003] Existing bridge collision protection devices mainly include attached collision protection devices and independent floating collision protection devices. Traditional attached collision protection devices are directly fixed to the surface of the bridge piers and cannot float with changes in water level. They are only suitable for inland river bridges with small water level fluctuations. Furthermore, traditional devices rely on the plastic deformation of a single material to absorb energy, with an energy absorption rate of less than 50%, and are prone to permanent deformation failure due to repeated impacts. While independent floating collision protection devices can adapt to water level changes, they are difficult to match with the variable cross-section design of bridge piers, resulting in excessive changes in protective gaps with water level and reduced protective effectiveness. Therefore, it is necessary to design a new bridge collision protection device to overcome the problems existing in traditional collision protection devices. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide a bridge anti-collision device based on tidal energy and magnetic levitation repulsion that is made of lightweight materials and suitable for variable cross-sections.

[0005] Technical Solution: The bridge collision avoidance device based on tidal energy and magnetic levitation repulsion described in this invention is installed on the outside of the bridge pier and includes a composite material collision avoidance system, a buffer layer, a tidal power generation system, a traction sliding system, and permanent magnets. Multiple permanent magnets are evenly arranged on the outside of the bridge pier. A traction sliding system is set on both sides of each permanent magnet and is connected to the composite material collision avoidance system. The composite material collision avoidance system is set in an arc shape and surrounds the outside of the permanent magnets. Buffer layers are set at both ends of each composite material collision avoidance system. Multiple tidal power generation systems are set on the lower side of the composite material collision avoidance system. The composite material collision avoidance system is equipped with a superconducting coil slot, in which a superconducting coil is placed. The tidal power generation system generates electricity, which makes the superconducting coil conductive and generates a magnetic field, magnetizing the steel hull and generating a repulsive force to avoid collision.

[0006] Furthermore, the composite material anti-collision system includes a rigid support connection layer, a first energy-absorbing layer, a second energy-absorbing layer, a third energy-absorbing layer, an outer ring layer, and a superconducting coil groove. The rigid support connection layer is sequentially connected to the third energy-absorbing layer, the second energy-absorbing layer, the first energy-absorbing layer, and the outer ring layer on its outer side, and a reserved groove is provided on its inner side. The rigid support connection layer is connected to the traction sliding system through the reserved groove.

[0007] Furthermore, the outer ring layer is made of fiberglass that is resistant to seawater corrosion and coated with an antifouling coating.

[0008] Furthermore, the first energy-absorbing layer is made of aluminum alloy with a honeycomb structure and filled with shear-thickening gel STF; the second energy-absorbing layer is made of closed-cell aluminum foam; and the third energy-absorbing layer is made of composite damping material.

[0009] Furthermore, the rigid support connection layer uses a carbon fiber-epoxy resin composite material as the support frame.

[0010] Furthermore, the tidal power generation system includes a base, a shell, a permanent magnet generator, a bottom guide plate, a slot, blades, a first guide component, a second guide component, a connecting rod, a main shaft, a top rod, a telescopic rod, and a recess. The base has a first guide component and a second guide component on its left and right sides, respectively, and a shell on its upper side. A main shaft is provided between the shell and the base. The main shaft is connected to multiple blades at the top and bottom via top rods. The multiple blades are connected and rotate around the main shaft. A telescopic rod and a connecting rod are provided at the connection between the top rod and the blades. A recess is connected between the top rod and the base and the shell, and the recess is fixed on the main shaft.

[0011] Furthermore, a permanent magnet generator connected to the main shaft is disposed in the middle of the housing.

[0012] Furthermore, both the first and second flow guiding components are provided with slots, and a bottom flow guiding plate is connected between them, with the bottom flow guiding plate fixed to the base.

[0013] Furthermore, the traction sliding system includes a composite material slider, a composite material chain, a composite material ring, and a composite material groove. The composite material slider is embedded in the composite material groove and slides up and down along the groove. One end of the composite material chain is connected to the composite material slider, and the other end is connected to the composite material ring.

[0014] Furthermore, the composite material ring passes through the reserved groove and is fixedly connected to the rigid support connection layer.

[0015] Working principle: This invention adopts magnetic levitation active defense. The magnetic field of the anti-collision device covers the surrounding water. After the steel hull enters the magnetic field range, its internal magnetic domains are magnetized, and the side close to the anti-collision device forms the same magnetic pole as the anti-collision device. The repulsive force pushes the ship away, preventing the ship from actively colliding with the bridge pier, effectively preventing the ship from directly damaging the bridge pier. After the magnetic levitation active defense fails, the buffer layer reduces the kinetic energy of the ship collision.

[0016] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: It effectively prevents direct damage from ships to bridge piers by employing multi-stage material energy absorption and a buffer layer to reduce the kinetic energy of ship impacts. The materials are lightweight and resistant to seawater corrosion. It utilizes tidal energy for self-powered operation, integrating a bidirectional vertical axis turbine unit at the bottom of the anti-collision device to generate electricity using tidal fluctuations. A flow battery stores basic energy, and a supercapacitor provides instantaneous high-power output to meet peak magnetic repulsion requirements. It is low-carbon and environmentally friendly, suitable for offshore bridges without grid coverage. The distributed segmental design provides multi-stage flexible protection for the bridge piers, effectively reducing damage from repeated wave action and preventing breakage. Vacuum-injected integrated molding allows for rapid replacement, reducing maintenance costs. It can be integrated with marine sonar systems and sensors for real-time monitoring and a graded response strategy, employing different magnetic field strengths under different conditions to reduce energy consumption.
