In addition, by arranging the buffer protection layer 8 to be transparent and coating the inner bottom surface with the noctilucent paint, when the rubber fender 1 is used, because the rubber fender 1 is arranged at the edge of the wharf, the surface of the rubber fender 1 is completely exposed outside, namely the buffer protection layer 8 and the pressure protection plate 9 are also completely exposed outside, when light is emitted at the wharf, the light is irradiated on the surface of the buffer protection layer 8, because the surface of the buffer protection layer 8 is transparent, the light penetrates through the top surface of the buffer protection layer 8 and is irradiated on the inner bottom surface of the buffer protection layer 8 in a large amount, so that the noctilucent paint on the inner bottom surface absorbs light energy, at night, the noctilucent paint on the inner bottom surface of the buffer protection layer 8 starts to emit light, thereby the outer surface of the rubber fender 1 presents obvious light, when a ship approaches the shore at night, the wharf can be effectively aligned, and the position of the rubber fender 1 can be accurately aligned, carry out effective buffering to when avoiding current boats and ships to lean on the shore at night, unable accurate be close to the pier place, and unable effectual alignment rubber protects the position at porthole 1, and then lead to boats and ships to bump when the bank, thereby cause the problem that the hull damaged.
Referring to fig. 1-2, the first magnetic plate 10 and the second magnetic plate 11 are both rectangular, the first magnetic plate 10 and the second magnetic plate 11 are both magnetic and repulsive, by providing the first magnetic plate 10 and the second magnetic plate 11, when a ship is driven to a dock to land, the ship impacts the pressure protection plate 9 to deform the pressure protection plate 9 downward and further to squeeze the buffer protection layer 8, the buffer protection layer 8 deforms along with the pressure protection plate 9, so that the first magnetic plate 10 is close to the second magnetic plate 11 downward, and further the first magnetic plate 10 and the second magnetic plate 11 generate a magnetic repulsion action therebetween, thereby preventing the ship from directly contacting the surface of the rubber fender 1 and preventing the ship from rubbing against the surface of the rubber fender 1 during the impact process, thereby generating a large amount of heat energy, which further causes severe thermal corrosion and abrasion of the surface of the rubber fender 1, and the first magnetic plate 10 and the second magnetic plate 11 generate magnetic repulsion force, so that the impact force caused by a part of ships can be effectively offset or consumed, the buffering force on the outer surface of the rubber fender body 1 is further enhanced, and the damping effect of the rubber fender body 1 is better.
The using method of the invention has the following working principle:
when the rubber fender body 1 needs to be installed, firstly, the fixed lantern rings 2 are respectively and fixedly installed at two ends of the rubber fender body 1, after the fixed lantern rings 2 are installed, the buffer protection layer 8, the pressure protection plate 9, the first magnetic plate 10 and the second magnetic plate 11 are sequentially assembled, so that each buffer protection layer 8, the pressure protection plate 9, the first magnetic plate 10 and the second magnetic plate 11 form a group of structure, then each group of assembled buffer protection layer 8, pressure protection plate 9, first magnetic plate 10 and second magnetic plate 11 are in butt joint adsorption with the magnets around the vent hole 7 through the magnets at two ends of the buffer protection layer 8, so as to complete the fixed assembly, after all the buffer protection layer 8, the pressure protection plate 9, the first magnetic plate 10 and the second magnetic plate 11 are installed, the lock chain is fixedly connected with two ends of the rubber fender body 1 through the existing lock chain structure, after the rubber fender body 1 is confirmed to be installed, the whole device is placed on the sea surface and naturally floats.
When boats and ships sailed to the pier, when backing into the shore, boats and ships bump with the pressurized backplate 9 of rubber fender side 1 one side, pressurized backplate 9 pressurized is inside or down to be deformed, when pressurized backplate 9 deforms, pressurized backplate 9 extrudees buffering inoxidizing coating 8 simultaneously, then buffering inoxidizing coating 8 is along with the same deformation of pressurized backplate 9, then this moment, first magnetic sheet 10 is close to second magnetic sheet 11 gradually, produce magnetism between first magnetic sheet 10 and the second magnetic sheet 11 and repel the effect, thereby avoid boats and ships and rubber fender side 1's surface to produce direct contact, and simultaneously, rubber fender side 1, buffering inoxidizing coating 8, pressurized backplate 9, first magnetic sheet 10, second magnetic sheet 11 mutually supports, play the absorbing effect of buffering to boats and ships.
When the buffering protective layer 8 is extruded, the gas in the inner cavity of the buffering protective layer 8 is extruded to flow outwards, the extruded gas flows into the piston bag 5 through the vent 7, the inner cavity of the piston bag 5 begins to expand, when the piston bag 5 expands, the piston bag 5 extrudes the piston plate 3 forwards to further push the piston plate 3 to move forwards, at the moment, if the water amount in the inner cavity of the fixed sleeve ring 2 is small and the condition that a large amount of water can overflow outwards through the bypass port 4 cannot be met, the piston plate 3 extrudes the inner cavity of the fixed sleeve ring 2 forwards to enable the accumulated water in the fixed sleeve ring 2 to be collided, the accumulated water generates oscillation under the movement of the piston plate 3, the oscillated water splashes on the surface of the piston plate 3 to cause certain counter-impact force to the piston plate 3, and through the surging of the gas in the buffering protective layer 8 and the counter-acting force of the accumulated water, the collision force caused by the ship and received by the buffering protective layer 8 is effectively reduced, can be if the water yield is more in the 2 inner chambers of fixed lantern ring, and when satisfying the condition that the excessive outward overflow of 4 of circuitous mouth of accessible, the inner chamber of the fixed lantern ring 2 of 3 extrusion of piston board, 2 inner chambers of fixed lantern ring diminish, and the water yield in the 2 inner chambers of fixed lantern ring is sufficient, then this moment, water receives the squeezing action of piston board 3, can be through circuitous mouth 4, reverse overflow, and pass through the hose, rethread inlet outlet 6, spray to the space between buffer protection layer 8 and the pressurized backplate 9, the water that spills over flows around on the surface of buffer protection layer 8 and pressurized backplate 9, thereby when boats and ships striking, to boats and ships surface and buffer protection layer 8, pressurized backplate 9 surface is cooled down.
When in the daytime, the light shines on the surface of buffering inoxidizing coating 8, at this moment, the light sees through the top surface of buffering inoxidizing coating 8, shine in a large number at the inboard bottom surface of buffering inoxidizing coating 8, make the night light coating on the inboard bottom surface absorb light energy, and when having arrived night, the night light coating of the inboard bottom surface of buffering inoxidizing coating 8 begins to give off the light, thereby make the surface of rubber fender body 1 demonstrate conspicuous light, when making boats and ships carry out the bank at night, can effectively find the pier place, and can be accurate go up rubber fender body 1 place, effectively cushion.
If when a certain buffering inoxidizing coating 8 takes place to damage, through artifical manual outside pulling in the both ends of buffering inoxidizing coating 8, make the magnet separation of attracting each other between blow vent 7 and the buffering inoxidizing coating 8, make buffering inoxidizing coating 8 break away from rubber fender side body 1 to accomplish the dismantlement, adsorb the butt joint with new buffering inoxidizing coating 8 again with blow vent 7, can accomplish the change.
