Description

Technical Field

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

[0002] Ship anti-collision protection device refers to a device that prevents direct collision between ships and berthing buildings, and is used to absorb and reduce the impact energy when ships approach or leave the dock. It is also called rubber fender. Rubber fender has the characteristics of good elasticity, high energy absorption, easy maintenance, long service life and convenient mass production. It is widely used in Japan, Europe, the United States and Southeast Asian countries. Rubber fender can not only protect ships and docks, but also reduce the horizontal load acting on the dock and improve the dock's berthing capacity. Rubber fenders mainly include shear type, rotation type, compression type, inflatable type and water pressure type. Among them, the compression type rubber fender has the characteristics of simple structure, easy manufacturing and convenient installation.

[0003] When a ship is docked and in contact with the dock, it will be impacted and squeezed by the ship. Since the surface of the protective device is set with chains and the rubber is deformable, there will be slippage between the pressure plate and the dock due to insufficient friction when squeezed. As a result, the ship is not stable enough when docking and is prone to lose balance, and the protective device is also easily damaged.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-3 and Figure 8 As shown, a ship mooring anti-collision protection device comprises a hull 1, a side wall of the hull 1 is provided with an anti-collision mechanism, the anti-collision mechanism comprises a rubber tube 202 and a pressing sheet 201, the surface of the pressing sheet 201 is fixed to the end face of the rubber tube 202, a round block 2071 is fixed to the other end of the rubber tube 202, and a cylinder is installed inside the hull 1;

[0033] A fixing frame 206 is fixed on the back of the pressing sheet 201, and rollers I 203 are slidably connected to the upper and lower ends of the fixing frame 206. Openings are provided on the upper and lower surfaces of the pressing sheet 201, and rollers I 203 penetrate the openings and are located on the front surface of the pressing sheet 201. A fixing ring 207 is rotatably connected to the front surface of the round block 2071, and 210 is fixed to the side surface of the hull 1. Fixing rods I 2051 are distributed on the circumference of the surface of 210, and the ends of the fixing rods I 2051 are rotatably connected to the pressing wheel 205;

[0034] The two ends of the roller I 203 are rotatably connected with the telescopic block 2031, and the two ends of the roller I 203 pass through the interior of the telescopic block 2031. The telescopic block 2031 is located inside the fixed frame 206 and slides through the spring III 2062. A fixed rod I 2064 is fixed to one side of the inner wall of the fixed frame 206. The spring III 2062 is sleeved on the surface of the fixed rod I 2064 and the end thereof is against the surface of the telescopic block 2031. The interior of the telescopic block 2031 is slidably connected with the moving rod II 2063 through the spring I. The end of the fixed rod I 2064 can be inserted into the interior of the telescopic block 2031 and contact the end of the moving rod II 2063 to push it to move.

[0035] A clamping block 2065 with a clamping function is slidably connected inside the telescopic block 2031 through a spring I. There are two clamping blocks 2065 and they are symmetrically distributed around the roller I 203 to clamp it. A slide groove II 2066 is provided on the surface of the clamping block 2065. A roller III 2061 is movably provided inside the slide groove II 2066. The surface of the roller III 2061 is rotatably connected to the end of the moving rod II 2063. A rotating ring 208 is rotatably installed on the back of the pressing plate 201. A hinged rod 204 is hinged between the rotating ring 208 and the fixed ring 207. When the pressing plate 201 moves to a position close to the cylinder, the pressing plate 201 and part of the round block 2071 move into the hull 1. When the hinged rod 204 moves into the hull 1, it contacts the pressing wheel 205 to stretch it and straighten it and move it into the hull 1. A spring III 2062 is fixed inside the fixing frame 206.

[0036] When the ship is docked, the cylinder driving shaft pushes the pressing sheet 201, the rubber cylinder 202 and the round block 2071 to the outside of the hull 1, and then the roller I 203 and the pressing sheet 201 contact the dock surface, and the rubber cylinder 202 is compressed to buffer the impact force generated when the ship contacts the dock.

[0037] The roller Ⅰ 203 first contacts the dock surface, and the impact force of the ship causes the roller Ⅰ 203 and the telescopic block 2031 to move toward the inside of the fixed frame 206. At this time, the moving rod Ⅱ 2063 moves in the same direction as the telescopic block 2031. The telescopic block 2031 moves toward the direction of the fixed rod Ⅰ 2064 inside the fixed frame 206. The fixed rod Ⅰ 2064 penetrates the inside of the telescopic block 2031 and contacts the end of the moving rod Ⅱ 2063, pushing the moving rod Ⅱ 2063 toward the clamping block 20 65, roller III 2061 moves laterally inside the slide groove II 2066 along with the moving rod II 2063, and when roller III 2061 moves horizontally through the inclined surface of the slide groove II 2066, the symmetrical clamping block 2065 clamps roller I 203 to prevent it from rotating, so that when the ship contacts the dock, roller I 203 is prevented from rotating, thereby increasing the friction between roller I 203 and the dock, so that the ship remains stable when docking;

[0038] When the pressing piece 201 contacts the dock, the rubber tube 202 is made of a relatively soft material and is easily deformed when squeezed, causing the pressing piece 201 to slide down along the dock surface. Therefore, by setting the hinged rod 204, the original chain design is replaced with the hinged rod 204. Since the hinged rod 204 has a relatively high stability, the hinged rod 204 forms a folded shape when the rubber tube 202 is compressed, and can prevent the pressing piece 201 from sliding down and deforming when contacting the dock, so that the pressing piece 201 and the round block 2071 can always be kept at the same level; and when the ship is traveling, the pressing piece 201 and the fixing ring 207 need to be stored in the hull 1 through the cylinder. When entering the hull 1, the hinged rod 204 contacts the surface of 205 to flatten it and then enter the hull 1, so that it can be stored during traveling, and avoid being eroded by seawater for a long time in the outside world and shortening its service life.

[0039] Embodiment 2

[0040] Based on Example 1, please refer to Figure 4-7 As shown, wiping pads 2042 are provided on both sides of the hinged rod 204 for vertical sliding. A slide groove Ⅰ 2049 is provided on the surface of the wiping pad 2042. A push rod 2048 is movable inside the slide groove Ⅰ 2049. A sleeve frame 2047 is fixed on the outer wall of the push rod 2048. The sleeve frame 2047 is a U-shaped structure. The sleeve frame 2047 is respectively sleeved on both ends of the moving rod Ⅰ 2044; a moving rod Ⅰ 2044 is fixed on the surface of the sleeve frame 2047. A gear 2046 is meshed between the two moving rods Ⅰ 2044. The gear 2046 is rotatably installed inside the hinged rod 204 through a connecting rod 2043.

[0041] A notch is provided at the end of the hinged rod 204, and the end of the push rod 2048 extends to the outside of the groove of the hinged rod 204, and the end of the push rod 2048 is an arc-shaped block structure; the two ends of the wiping pad 2042 are located inside the hinged rod 204 and are connected with a spring II, and the spring II is located at the bottom of the two ends of the wiping pad 2042; a circular groove is provided on the edge of the round block 2071, and a plurality of circumferentially distributed rotating rods 2072 are fixed on the edge of the fixed ring 207, and the rotating rod 2072 is embedded in the circular groove on the edge of the round block 2071 and rotates, and the rotating rod 2072 is connected to the end of the piston, and the cylinder drives the rubber tube 202 and the pressing sheet 201 to move linearly and drives the fixed ring 207, the hinged rod 204 and the rotating ring 208 to rotate through the rotating rod 2072.

[0042] When the cylinder pushes the pressing sheet 201 outward to make the hinge rod 204 in a plane shape, the ends of the two push rods 2048 inside the hinge rod 204 push each other to move inside the hinge rod 204 when they touch each other, and the roller II 2050 moves horizontally inside the slide groove I 2049, and pushes the wiping pad 2042 to move to the surface of the rubber tube 202 and contact it when passing through the inclined surface of the slide groove I 2049, and then the cylinder is started to drive the rotating rod 2072, the fixed ring 207, the hinge rod 204 and the rotating ring 208 to rotate, and the wiping pad 2042 is located on the surface of the rubber tube 202 to automatically wipe the seawater adhered to it, so as to avoid the seawater from being located on the surface of the rubber tube 202 for a long time to corrode it and affect its subsequent use;

[0043] In the above, when one of the push rods 2048 moves inside the hinged rod 204, the end of one of the moving rods I 2044 engages with the gear 2046 to drive the other moving rod I 2044 and the rotating ring 208 to move in the opposite direction, so that the two ends of the wiping pad 2042 are symmetrically lowered, thereby preventing the wiping pad 2042 from getting stuck due to uneven force when it descends; and through the setting of spring II, when not in use, the two ends of the wiping pad 2042 are pushed upward by the deformation expansion generated by spring II, so that it does not contact the surface of the rubber tube 202 and does not protrude from the bottom of the hinged rod 204. When not in use, the wiping pad 2042 can be protected to prevent it from being wetted and corroded by seawater.
