Description
Technical Field
[0001] The utility model relates to the technical field of ships, and more specifically, to an anti-collision device for ship berthing. Background Art
[0002] Ship or vessel refers to any means of transportation that uses the buoyancy of water, relies on power such as human power, sails, engines (such as steam engines, gas turbines, diesel engines, nuclear power units), etc., to pull, pull, push, row, or propel propellers and high-pressure nozzles to move on water. In addition, civilian ships are usually called ships, ships, engines, and boats, military ships are called ships, small ships are called boats, sampans, rafts or boats, and they are collectively called ships or vessels. When a ship is docked, the hull itself will have inertia, causing the side of the hull to collide with the shore.
[0003] For example, the authorization announcement number CN220640190U discloses a ship anti-collision device, in which a fixed plate is arranged on one side of a mounting plate, the fixed plate is slidably connected to the mounting plate through a limit sliding assembly, an adjustment assembly for moving the fixed plate up and down is arranged between the fixed plate and the mounting plate, a plurality of groups of anti-collision assemblies are arranged on a side of the fixed plate away from the mounting plate, the limit sliding assembly enables the fixed plate to move up and down only, and the anti-collision assembly on the fixed plate can be moved up and down to adjust the height by manually adjusting the adjustment assembly, so that it can cope with buildings on the shore of different heights and the hull can be better protected, and only the adjustment assembly needs to be adjusted, which is very convenient and simple to operate.
[0004] In the above scheme, the air cushion first contacts the impact object during collision. The air cushion material itself has the ability to buffer. Then the impact force is transmitted to the slider through the support rod. The slider pushes the springs on both sides respectively. However, the springs will deform during long-term use, resulting in reduced shock absorption effect and affecting the anti-collision effect. Utility Model Content

[0022] like Figure 1 As shown,
[0023] The anti-collision device for ship docking comprises a mounting plate 1 connected to the side wall of the ship. The side wall of the mounting plate 1 is provided with an anti-collision device. The anti-collision device has multiple groups, which are evenly distributed on the outer wall of the ship and are used to protect the side of the ship when the ship is docked.
[0024] The anti-collision device includes an anti-collision air cushion 1 2 , a rubber column 3 , an anti-collision air cushion 2 4 and a resistance unit 5 .
[0025] The inflation amount of the anti-collision air cushion 1 2 and the anti-collision air cushion 2 4 is 60% to 80% of the volume of the anti-collision air cushion 1 2 and the anti-collision air cushion 2 4, so as to prevent the anti-collision air cushion 1 2 and the anti-collision air cushion 2 4 from bursting due to over-inflation when being stressed.
[0026] The anti-collision air cushion 1 2 is connected to the side wall of the mounting plate 1, one side wall of the rubber column 3 is connected to the anti-collision air cushion 1 2, and the other side wall of the rubber column 3 is connected to the anti-collision air cushion 2 4. The side walls of the anti-collision air cushion 1 2 and the anti-collision air cushion 2 4 are both provided with a through hole 12 connected thereto, and the rubber column 3 is provided with a docking hole 13 connected to the through hole 12, so that the anti-collision air cushion 1 2 and the anti-collision air cushion 2 4 are connected to each other, and the force can be absorbed by the flow of airflow when subjected to force.
[0027] A metal bellows 14 is fixedly connected in the docking hole 13 to prevent the rubber column 3 from deforming and blocking the docking hole 13 when force is applied to the rubber column 3. At the same time, the metal bellows 14 can be relatively expanded and contracted according to the force applied to the rubber column 3.
[0028] An air-inflating hole is provided on the upper end surface of the anti-collision air cushion 2, and a sealing plug 15 is provided on the air-inflating hole. During long-term use, the anti-collision air cushion 2 can be inflated.
[0029] A connecting tube is provided in the air hole, a thread 1 is provided on the inner wall of the connecting tube, and a thread 2 is provided on the outer wall of the sealing plug 15. The anti-collision air cushion 2 is sealed by fastening the threads of the sealing plug 15 and the connecting tube to prevent the anti-collision air cushion 2 from being stressed and leaking.
[0030] The resistance unit 5 includes a connecting plate 6 connected to the anti-collision air cushion 2 4 and a resistance rod 7 placed on the connecting plate 6 . A sliding groove 8 is provided on the connecting plate 6 . Elastic columns 9 are provided at both ends of the sliding groove 8 .
[0031] The resistance rod 7 is connected to the elastic column 9. The two resistance rods 7 are cross-arranged. The intersection of the two resistance rods 7 is hinged. A rotating rod passing through the resistance rod 7 is provided at the intersection of the two resistance rods 7. Both resistance rods 7 are rotatably connected to the rotating rod. Both ends of the rotating rod are limited. When subjected to force and compression, the resistance rod 7 slides in the slide groove 8, causing the elastic column 9 to deform.
[0032] A spring 10 is embedded in the elastic column 9 , which can increase the strength of the elastic column 9 and enhance the anti-collision effect.
[0033] The end surface of the resistance rod 7 is provided with an air cushion ball 11 in contact with the dock, and the air cushion ball 11 absorbs the force in the first step.
[0034] Working principle: When the ship is docked, the air cushion ball 11 is first subjected to pressure. Under the action of pressure, the two resistance rods 7 slide in the slide groove 8, squeezing the elastic column 9. The elastic column 9 is squeezed and deformed. The elastic column 9 and the spring 10 located in the elastic column 9 absorb part of the force. Then the force continues to be transmitted, and the air in the anti-collision air cushion 2 4 is squeezed into the anti-collision air cushion 1 2. While unloading the force, it also avoids damage to the anti-collision air cushion 2 4 due to the force. If the gas in the anti-collision air cushion 1 2 and the anti-collision air cushion 2 4 is reduced, the sealing plug 15 can be opened and air can be pumped into the anti-collision air cushion 1 2 with an air pump.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
