Description
Technical Field
The invention relates to an anti-collision device, in particular to a rotary guide composite material anti-collision device, and belongs to the technical field of building protection.
Background
With the continuous development and utilization of marine resources by human beings, marine accidents are more and more. The most frequent marine collision event is the event of an offshore structure being struck by a vessel. In the event of an accident, the most direct hazards are the collapse of structures, damage to ships and casualties on ships. Meanwhile, ship fuel leakage caused after collision pollutes the marine environment and destroys ecological balance.
In order to solve unnecessary loss caused by accidents, a series of measures are adopted to protect offshore structures. In order to protect the integrity of the structure, mankind invented a steel structure marine protection device. In order to avoid the impact of the ship on the structure, people invent floating anti-collision nets. In order to protect ships and offshore structures simultaneously, people invent elastic bumpers made of plastic and the like.
However, such a bumper often cannot achieve the expected effect of human beings, a high-strength steel structure anti-collision device cannot resist corrosion, and high-concentration marine microorganisms can rapidly corrode a steel structure, so that the steel structure cannot achieve sufficient strength and needs to be replaced frequently. The floating anti-collision net often cannot have a good effect, and the ship cannot accurately avoid the offshore structure. The elastic bumper made of plastic materials cannot achieve the due strength, and can only protect the structure from being directly impacted by a small ship.
Therefore, from the perspective of safety and environmental protection, an effective bumper is important for protecting ships and offshore structures.

Detailed Description
The following describes in detail a specific embodiment of the present invention with reference to fig. 1 to 5.
As shown in fig. 1 and 5, the rotary guide composite material bumper comprises bumper monomer structures 1, supports 2 and platforms 4, wherein the annular platforms 4 surround the periphery of a connecting pile body 3, the supports 2 are connected to the periphery of the platforms 4, and the plurality of bumper monomer structures 1 are connected through the supports 2 and arranged on the periphery of the supports 2. The bracket 2 is assembled together by nylon rods, and the nylon rods are connected together by pins.
As shown in fig. 2, the bumper unit structure 1 is a winged bucket structure connected to a platform 4 through a bracket 2, and is composed of an inner shell 5, an outer shell 7, projecting wings 8, and a foam energy absorbing filler 6. As shown in fig. 3, the energy-absorbing filler 6 is arranged between the inner shell 5 and the outer shell 7, and is a plurality of groups of strip-shaped energy-absorbing fillers arranged together in the same direction with the pile body 3. The cross section of the energy-absorbing filler 6 adopts a honeycomb hexagonal structure. The plurality of groups of strip-shaped energy-absorbing fillers are separated by the FRP films.
A vertical rod 51 is arranged in the middle of the inner shell 5, and two ends of the vertical rod 51 are connected with the bracket 2. The inner shell 5, the outer shell 7, the projecting wings 8 and the platform 4 are all FRP materials. The support 2 comprises an inner ring support 21, a protruding support 22 and an outer ring support 23, the inner ring support 21 being connected with the platform 4. The protruding support 22 is divided into an upper layer and a lower layer and is arranged outside the inner ring support 21, and the outer end part of the protruding support 22 is connected with two ends of the vertical rod 51. The outer end portions of all the outriggers 22 are connected to the outer ring bracket 23, thereby connecting all the bumper unit structures 1 and the brackets 2 as a whole. The bottom of the vertical rod 51 is connected with the lower protruding bracket 22 through a bolt. A plurality of support rods are arranged in the support 2 to enhance the stability of the support.
As shown in fig. 1-3, a plurality of projecting wings 8 are uniformly disposed on the outer surface of the housing 7. The extending wing 8 is in a spiral curved surface fan blade shape, and is wrapped with a steel bar or a metal sheet to prevent the extending wing 8 from being bent and damaged. Each bumper unit structure 1 includes 3 protruding wings 8 to be rotated by the impact of the water flow.
As shown in fig. 4, in this embodiment, the platform 4 is formed by assembling 8 pieces, each piece is formed by an external FRP structure and an energy-absorbing filler 6 wrapped therein.
In this embodiment, a layer with a higher friction coefficient is adhered to the outer surface of the housing 7 to increase the friction energy consumption with the ship body. The outer surface of the inner shell 5 is adhered with a layer with a lower friction coefficient so as to facilitate the rapid rotation of the bumper monomer structure 1.
According to the invention, the single-body structure 1 of the anti-collision device with the extending wings can rotate by utilizing water waves generated when a ship drives, and the rotation characteristic can cause the ship to generate lateral acceleration at the first moment when the ship collides with the anti-collision device, so that the original forward collision of the ship is changed into lateral collision, and the impact force is reduced.
When the bumper is impacted, the bumper monomer structure 1 is in contact with a ship, the extending wings 8 extend out, and compared with a traditional cylindrical bumper, water can cause large resistance to the bumper monomer structure, and the damping constraint effect can play a good energy consumption role.
Furthermore, the kinetic energy of the vessel is converted into a part of the kinetic energy of the crash barrier cell structure 1 upon collision, so that the rotation of the crash barrier cell structure 1 can also consume a part of the energy. Meanwhile, after collision, the bumper monomer structure 1 is deformed due to collision, the foam filled inside can be damaged and deformed, the FRP materials of the outer shell and the inner shell can also be damaged and deformed, and each structure is damaged to absorb a large part of energy.
The FRP material used in this example, an internally filled foam structure, a nylon scaffold structure. The structures have the characteristic of corrosion resistance in water, are light in weight and good in energy absorption effect, cannot be easily deformed and aged or damaged, and therefore do not need to be replaced frequently and are long in service life.
In addition, the embodiment adopts an assembly type structure, and all components can be manufactured in a factory and transported to a construction site for assembly and use. Therefore, the construction period can be greatly reduced, and the inconvenience brought to the construction by weather is eliminated. Meanwhile, the assembly type structure can replace damaged accessories at any time, and only new accessories need to be dismounted and reinstalled.
The above-mentioned embodiments are only given for the purpose of more clearly illustrating the technical solutions of the present invention, and are not meant to be limiting, and variations of the technical solutions of the present invention by those skilled in the art based on the common general knowledge in the art are also within the scope of the present invention.
