[0002] Fender, also known as ship's fender, is an elastic buffer device used on the edge of dock or ship. It can be made of wood or rubber. It is mainly used to reduce the impact force between the ship and the dock or between the ship and the dock during docking or mooring, and reduce or eliminate the damage to the ship and dock. The conical rubber fender is the third generation of the drum fender. Its conical shape enables the fender to withstand forces at various complex angles, with increased deformation, high energy absorption and longer service life.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 4 As shown, a conical rubber fender device with a groove structure drainage function includes a dock structure 1, and a rubber fender 4 is arranged on the dock structure 1:

[0036] The rubber fender 4 is composed of a conical and hollow fender portion 41, a mounting portion 42 and a buffer portion 45. The mounting portion 42 is located at the bottom of the fender portion 41 and is fixedly connected to the dock structure 1, so that the axis of the fender portion 41 can be parallel to the water surface and perpendicular to the vertical surface of the dock structure 1. The buffer portion 45 is located at the top of the fender portion 41, so that the buffer portion 45 can be located outside the rubber fender 4 and can first contact with the force when the ship is docked.

[0037] The bottom of the mounting portion 42 is provided with a flow guide channel communicated with the inner cavity of the fender portion 41, which can provide a channel for the water in the rubber fender 4 to flow out when the rubber fender 4 is squeezed and deformed after contacting the ship, so that the water in the rubber fender 4 can be quickly discharged, and the deformation rate of the rubber fender 4 is accelerated, thereby reducing the reaction force on the rubber fender 4 and the ship caused by the water in the rubber fender 4 flowing out slowly, ensuring that the rubber fender 4 can more easily absorb the impact energy when the ship is berthing, thereby protecting the structural safety of the ship and the dock structure 1;

[0038] The buffer portion 45 has a buffer position for compression deformation after contacting the ship and a support position for elastic restoration after separation from the ship in its stroke. When the ship collides with the buffer portion 45, the force exerted by the ship on the rubber fender 4 from different angles can be buffered and pressure-relieved, and the buffer portion 45 can be moved from the support position to the buffer position, ensuring that the impact forces at different angles can act on the fender portion 41 along the axial direction of the rubber fender 4, thereby effectively reducing the shear force on the rubber fender 4, making it safer, more reliable, stronger and more durable.

[0039] The diversion channel is a diversion groove 44, and the number of the diversion grooves 44 is several, and they are distributed in an equiangular ring at the bottom of the mounting portion 42. When the ship berths and collides with the rubber fender 4, the impact force of the ship berthing will act on the rubber fender 4, so that the rubber fender 4 is squeezed and compressed and deformed. At this time, the water flow in the rubber fender 4 will be squeezed and discharged outward from the diversion groove 44, which can accelerate the deformation rate of the rubber fender 4, thereby reducing the reaction force on the rubber fender 4 and the ship caused by the slow outflow of the water flow in the rubber fender 4, ensuring that the rubber fender 4 can more easily absorb the impact energy when the ship berths, thereby protecting the structural safety of the ship and the dock structure 1.

[0040] The mounting portion 42 is provided with a plurality of positioning holes 43 which are offset from the guide groove 44, and positioning bolts 3 extending into the dock structure 1 are penetrated through the positioning holes 43. The mounting portion 42 is placed at the installation location of the dock structure 1, and the positioning bolts 3 are penetrated through the positioning holes 43 and driven into the dock structure 1, so that the position of the rubber fender 4 can be installed and fixed.

[0041] The buffer portion 45 includes a buffer base 451 arranged on the top of the fender portion 41, a buffer groove 453 is provided on the buffer base 451, and a rubber ball 455 is arranged in the buffer groove 453, and a buffer block 454 is arranged on the outside of the rubber ball 455, and a buffer touch plate 452 is arranged on the outside of the buffer block 454, and the rubber balls 455 are distributed in the buffer groove 453 in two rows of annular structures. When the buffer touch plate 452 is not under pressure, the rubber ball 455 is in a normal state, so that the buffer touch plate 452 is in a supporting position. When the ship berths and generates pressure on the rubber fender 4, the buffer touch plate 452 will be compressed and the pressure will be transmitted to the buffer block 454, so that the buffer block 454 squeezes the rubber ball 455 to deform it, so as to buffer and relieve the pressure of the instantaneous large impact force on the rubber fender 4, and prevent the rubber fender 4 from being seriously deformed due to the instantaneous excessive force.

[0042] The buffer block 454 includes a conducting portion 4541 in contact with the buffer touch plate 452, the end of the conducting portion 4541 is provided with a contact portion 4542 extending into the buffer groove 453, the outer wall of the contact portion 4542 is provided with an annular groove 4543 adapted to the rubber ball 455, the outer diameter of the contact portion 4542 is smaller than the inner diameter of the buffer groove 453, when the ship is in a tilted state when berthing, the force of the ship berthing will act on the buffer touch plate 452 from different angles and directions, and the buffer touch plate 452 is subjected to different angles and directions. The force in the direction will be transmitted to the contact part 4542. At this time, the rubber ball 455 at the pressure position that is in direct contact with the berthing ship will be compressed and deformed in the annular groove 4543, and the buffer touch plate 452 will be deformed accordingly, so that the impact force of the ship berthing will act linearly on the rubber fender 4 and keep in stable contact with the contact surface of the ship, ensuring that the impact forces at different angles can act on the fender part 41 along the axial direction of the rubber fender 4, thereby effectively reducing the shear force on the rubber fender 4, making it safer, more reliable, stronger and more durable.

[0043] The outer wall of the buffer touch plate 452 is provided with a force plate 7, which can increase the contact surface area between the rubber fender 4 and the ship, and also prevent the rubber fender 4 from being excessively worn due to frequent collisions and contacts with the ship.

[0044] The inner wall of the load-bearing plate 7 is respectively provided with an upper traction steel cable 5 and a lower traction steel cable 6, and the free ends of the upper traction steel cable 5 and the lower traction steel cable 6 are provided with buried parts 2 located in the dock structure 1. The number of the upper traction steel cable 5 and the lower traction steel cable 6 is at least two, and they are symmetrically connected at the upper position and the lower position of the load-bearing plate 7, which can play a role in traction and reinforcement of the load-bearing plate 7 and prevent the load-bearing plate 7 from shaking or even falling off from the rubber fender 4.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
