Description

Technical Field

[0001] The present invention relates to the technical field of ship anti-collision devices, and in particular to a ship anti-collision device. Background Art

[0002] When loading and unloading, ships will dock at the dock. Since the ships are parked on the water, they will float with the waves. At this time, the ships are prone to collide with the dock, causing damage to the side walls of the ships and damage to the dock facilities. Therefore, buffer protection equipment needs to be installed.

[0003] A Chinese patent with announcement number CN114808853A discloses a ship mooring anti-collision stabilization device, which is equipped with an anti-collision plate and a rubber buffer bag. When the hull shakes, it will first hit the rubber buffer bag on the anti-collision plate to prevent the hull from directly colliding with the shore and being directly damaged. At the same time, through the cooperation of multiple buffer mechanisms, the ship mooring anti-collision stabilization device can have very good buffering performance, thereby ensuring the service life of the hull.

[0004] However, the above device can only cushion the ship in the direction perpendicular to the dock. Since the ship floats with the waves and moves in multiple directions, when the ship sways in the vertical direction, the rubber cushion bag is tightly attached to the side wall of the ship, the ship will generate lateral force on the rubber cushion bag, which will cause damage to the above device and fail to provide cushioning protection for the ship.

DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] Please refer to Figures 1 to 6 The present embodiment provides a ship anti-collision device for cushioning ships to avoid damage to ships. The device can be installed on ships or at locations such as docks. The ship anti-collision device of the present embodiment includes: a mounting body 1, an impact body 8, and a swing rod 2. The mounting body 1 is used for mounting and fixing the entire device. The impact body 8 is connected to a rubber anti-collision block 6 for bearing the impact force. The swing rod 2 is used to connect the mounting body 1 and the impact body 8. In the present embodiment, the swing rod 2 is connected to the mounting body 1 through a deflection buffer mechanism and an axial buffer mechanism. The deflection buffer mechanism is used to offset the lateral force and the axial force. The axial buffer mechanism is used to offset the axial force to avoid damage to the anti-collision device under the action of the lateral force, thereby causing the failure of the ship protection.

[0033] One end of the mounting body 1 is open, that is, it has an open end and a closed end. A fixing ring 10 is provided at the outer edge of the open end of the mounting body 1. A support ring 14 is provided inside the mounting body 1. The support ring 14 is arranged along the radial direction of the mounting body 1. One end of the swing rod 2 is connected to the impact body 8 through a ball hinge. The other end of the swing rod 2 passes through the support ring 14 and is connected to the mounting body 1 through a deflection buffer mechanism. The middle part of the swing rod 2 is connected to a support plate 11 through a deflection assembly. The support plate 11 is arranged along the radial direction of the mounting body 1 and slides with the inner side wall of the mounting body 1. The support plate 11 is connected to the swing rod 2 through an axial buffer mechanism. In this embodiment, the deflection buffer mechanism and the axial buffer mechanism are respectively located on both sides of the support ring 14.

[0034] The deflection assembly is arranged to provide a support point for the deflection of the swing rod 2. The deflection assembly includes a sphere 3 arranged on the swing rod 2 and a limit ring 4 arranged in the middle of the support plate 11. The outer side of the limit ring 4 is fixedly connected to the middle of the support plate 11, and the inner side wall of the limit ring 4 is a ring cut from a spherical surface, and the radius of curvature is the same as the radius of curvature of the sphere 3, and the inner side wall of the limit ring 4 is flush with the inner side wall of the sphere 3, and a plurality of first balls 20 are arranged between the inner side wall of the limit ring 4 and the sphere 3, and the first balls 20 can roll between the limit ring 4 and the sphere 3 to reduce the friction of the swing rod 2 during deflection. There is a gap between the two ends of the limit ring 4 and the swing rod 2, and the two ends of the limit ring 4 are provided with a closing section to prevent the first balls 20 from sliding out. This arrangement can prevent the first balls 20 from falling off, and can also ensure the contact between the swing rod 2 and the limit ring 4 during deflection.

[0035] The deflection buffer mechanism includes a plurality of deflection buffer components arranged between the mounting body 1 and the support ring 14, and all the deflection buffer components are evenly arranged around the swing rod 2. The deflection buffer component includes a fixed plate 19 slidably arranged on the mounting body 1, a second buffer 15 arranged between the fixed plate 19 and the support ring 14, a fixed column 22 arranged on the support ring 14, a roller frame 23 arranged on the fixed column 22, a guide roller 24 arranged on the roller frame 23, and a rope 17 passing around the guide roller 24. The sliding direction of the fixed plate 19 and the extension of the second buffer 15 are the same as the extension direction of the mounting body 1 (i.e., the axial direction of the mounting body 1, the same below), one end of the second buffer 15 is fixedly connected to the support ring 14, and the other end of the second buffer 15 is fixedly connected to the fixed plate 19. The two ends of the rope 17 are respectively connected to the fixed plate 19 and the swing rod 2, and the rope 17 always forms an acute angle after passing around the guide roller 24.

[0036] When the swing rod 2 deflects, different fixed plates 19 will be driven to have different displacements, thereby driving the corresponding second buffers 15 to move, thereby offsetting the lateral force that causes the swing rod 2 to deflect. Obviously, when the swing rod 2 is not deflected and is squeezed, all the fixed plates 19 are displaced in the same way, and at this time all the second buffers 15 also work synchronously, thereby offsetting the positive pressure on the swing rod 2. Therefore, the deflection buffer mechanism of this embodiment can not only offset the lateral force, but also offset the positive pressure.

[0037] The axial buffer mechanism includes a plurality of first buffers 13 arranged between the support ring 14 and the support plate 11. The number and position of the first buffers 13 correspond one-to-one to the second buffers 15. The extension direction of the first buffers 13 is the same as the extension direction of the mounting body 1, and the extension direction of the first buffers 13 is the same as the corresponding second buffers 15.

[0038] When the swing rod 2 is subjected to positive pressure, the swing rod 2 will drive the support plate 11 to move, thereby squeezing the first buffer 13, thereby offsetting the positive pressure. Since the second buffer 15 can also offset the positive pressure, and when offsetting the positive pressure, both the first buffer 13 and the second buffer 15 generate pressure on the support ring 14, therefore, the first buffer 13 corresponds to the second buffer 15 one by one, and the extension direction of the first buffer 13 and the corresponding second buffer 15 are consistent, which can ensure that the force positions on both sides of the support ring 14 correspond to each other, improve the force of the support ring 14, and increase the service life of the support ring 14.

[0039] In this embodiment, a plurality of first limiting slide rails 12 and a plurality of second limiting slide rails 16 are respectively provided on both sides of the support ring 14 along the extension direction of the mounting body 1. The first limiting slide rails 12 and the second limiting slide rails 16 are respectively fixedly connected to the inner side wall of the mounting body 1 and correspond one to one. The edge of the support plate 11 is slidably matched with all the first limiting slide rails 12, the fixed plate 19 corresponds one to one with the second limiting slide rails 16, and the fixed plate 19 is slidably matched with the corresponding second limiting slide rail 16. The sliding mode of the fixed plate 19 and the second limiting slide rail 16 includes but is not limited to T-type slide rails and the like.

[0040] In order to ensure the overall rigidity of the mounting body 1 , the mounting body 1 , the first limiting slide rail 12 , the second limiting slide rail 16 and the support ring 14 are integrally formed.

[0041] In order to ensure the normal operation of the deflection buffer mechanism and the axial buffer mechanism, in this embodiment, an elastic film 5 made of rubber is provided at the open end of the mounting body 1 to prevent dust from entering.

[0042] In order to improve the connectivity between the swing rod 2 and the impact body 8, in this embodiment, the swing rod 2 is connected to the impact body 8 through a plurality of first elastic telescopic rods 9. The first elastic telescopic rod 9 is arranged obliquely with the swing rod 2, and the two ends of the first elastic telescopic rod 9 are respectively hinged to the swing rod 2 and the impact body 8, the hinged position of the first elastic telescopic rod 9 and the swing rod 2 is located on the same cross section of the swing rod 2, and the hinged position of the first elastic telescopic rod 9 and the impact body 8 is located on the same circumference, and the center of the circumference is located at the ball hinge connection between the swing rod 2 and the impact body 8.

[0043] The impact body 8 has an open cavity and a mounting plate 7 on the side away from the swing rod 2. The side of the mounting plate 7 away from the impact body 8 is connected to a rubber anti-collision block 6. The impact body 8 is provided with a lateral buffer mechanism. The lateral buffer mechanism includes a fixed block 32 and a plurality of second elastic telescopic rods 30. The fixed block 32 is fixedly arranged at the center of the mounting plate 7, and the fixed block 32 and the rubber anti-collision block 6 are respectively located on both sides of the mounting plate 7. The fixed block 32 is provided with a third ball 33 rolling toward one side of the impact body 8, and the third ball 33 is in rolling cooperation with the bottom wall of the inner cavity of the impact body 8. All the second elastic telescopic rods 30 are evenly arranged around the fixed block 32, and the two ends of the second elastic telescopic rod 30 are respectively hinged to the impact body 8 and the fixed block 32, that is, the second elastic telescopic rod 30 can not only be telescopic, but also can be moved under the action of the hinge. The outer side of the sleeve of the second elastic telescopic rod 30 is provided with a second ball 31 facing the impact body 8, and the second ball 31 is also in rolling cooperation with the bottom wall of the inner cavity of the impact body 8.

[0044] When the rubber anti-collision block 6 slides under the action of the lateral force, it will drive the mounting plate 7 and the fixing block 32 to move synchronously, and all the second elastic telescopic rods 30 will be displaced and extended synchronously and coordinatedly, thereby offsetting the lateral force and ensuring that the entire device is not easily damaged under the action of the lateral force.

[0045] In this embodiment, in order to avoid damage to the entire device due to excessive lateral force, a mounting sleeve 25 is provided on the outer side of the mounting body 1 from its sealed end, and a mounting flange 26 is provided at the end of the mounting sleeve 25 away from the impact body 8 for connecting the entire device. The inner bottom wall of the mounting sleeve 25 is connected to the fixing ring 10 through an electric telescopic rod 27, and the extension direction of the electric telescopic rod 27 is consistent with the extension direction of the mounting body 1. At the same time, a pressure sensor 18 is provided between the fixing plate 19 and the second buffer 15, and the pressure sensor 18 and the electric telescopic rod 27 are communicated and connected with a controller, and the controller can optionally be a Siemens S7-200 series PLC controller.

[0046] The controller obtains the degree of deflection of the swing arm 2 based on the difference in pressure data fed back by each pressure sensor 18. When the threshold is exceeded, the electric telescopic rod 27 is retracted and then extended again to adjust the orientation of the impact body 8 and re-contact it, thereby effectively avoiding the failure of each buffer and elastic telescopic rod due to excessive lateral force.

[0047] In this embodiment, the structures of each buffer and the elastic telescopic rod, as well as the control principle of the controller belong to the prior art and will not be described in detail here.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
