[0048] When a collision occurs, the anti-collision strip 6 is impacted first, and the impact force is transmitted to the support rod 8, pushing the block 9 to move downward in the sleeve 7, causing the second spring 10 to be compressed to cushion the impact. When the impact load is released, the block 9 and the second spring 10 quickly return to their original state. The entire buffering process is stable, effectively protecting both parties of the collision and avoiding damage to the hull and injuries to personnel.

[0049] Embodiment three:

[0050] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on the above embodiment, further and optionally, the ship buffering and anti-collision device also includes a buffer mechanism arranged between the mounting seat 1 and the frame 5, and the buffer mechanism includes:

[0051] Two groups of slide grooves are symmetrically opened in the top of the base 4, and a slider 19 is slidably connected in each group of the slide grooves. The upper end of the slider 19 is movably connected to the inner top of the frame 5 through a second connecting rod 20. A push rod 21 is connected to the inner wall of one side of the slider 19, and a first air cavity is provided on one side of the push rod 21. A first piston 22 is slidably connected in the first air cavity, one end of the push rod 21 extends into the air cavity and is connected to the first piston 22, and one end of the first air cavity is connected to a first air pipe 23.

[0052] Specifically, the upper end of the second connecting rod 20 is hinged to the inner wall of the frame 5, and the lower end is hinged to the upper end of the slider 19. The side wall of the slider 19 is in sliding contact with the inner wall of the slide groove. One end of the slider 19 is fixedly connected to one end of the push rod 21, and the other end of the push rod 21 extends into the first air cavity and is fixedly connected to one end of the first piston 22. The side wall of the first piston 22 is in sliding contact with the inner wall of the first air cavity. The end of the first air cavity away from the push rod 21 is connected to the first air pipe 23, and the first air pipe 23 is connected to the interior of the first air cavity.

[0053] Further and optionally, the lower end of the first air pipe 23 passes through the support plate 2 and the block 3 in sequence and is connected to the second air pipe 24, one end of the second air pipe 24 is connected to the second air cavity, the second air cavity is located in the mounting seat 1, a third spring 27 is provided in the second air cavity, the top of the third spring 27 is connected to the second piston 26, the upper end surface of the second piston 26 is connected to the support rod 25, the upper end of the support rod 25 passes through the support plate 2 and is plugged into the bottom of the frame 5.

[0054] Specifically, the lower end surface of the first air pipe 23 is connected to the upper end surface of the second air pipe 24, so that the first air pipe 23 is connected to the second air pipe 24, one end of the second air pipe 24 is connected to the bottom of the second air cavity, the second air cavity is opened in the mounting seat 1, the bottom of the third spring 27 is fixedly connected to the bottom of the second air cavity, the upper end of the third spring 27 abuts against the lower end surface of the second piston 26, the side wall of the second piston 26 is in sliding contact with the inner wall of the second air cavity, the upper end surface of the second piston 26 is fixedly connected to the lower end of the support rod 25, the support plate 2 is provided with a hole allowing the support rod 25 to pass through, and the upper end of the support rod 25 passes through the hole and is plugged into the bottom of the frame 5;

[0055] When a collision occurs, the anti-collision strip 6 is impacted first, and the impact force is transmitted to the second connecting rod 20. The second connecting rod 20 pushes the slider 19 to move in the slide groove, and the slider 19 pushes the first piston 22 to move in the first air cavity toward the direction close to the first air pipe 23, so that the compressed air enters the first air pipe 23, and enters the second air pipe 24 through the first air pipe 23, and then enters the second air cavity;

[0056] When a collision occurs, the anti-collision strip 6 is impacted first, and the impact force is transmitted to the support rod 25. The support rod 25 pushes the second piston 26 to move downward in the second air cavity, so that the third spring 27 is compressed, so that the impact is buffered by the third spring 27. At the same time, the compressed air enters the second air pipe 24, and enters the first air pipe 23 through the second air pipe 24, and then enters the first air cavity;

[0057] In this way, the air in the first air cavity and the second air cavity are relative to each other, forming resistance to the first piston 22 and the second piston 26, thereby playing a buffering role. Multiple buffers are combined to improve the buffering effect of the device.

[0058] Further and optionally, the upper end surface of the second air pipe 24 is fitted with the lower end surface of the first air pipe 23 , and two groups of connecting rings 28 are provided inside the fitting portion, and the insides of the two groups of connecting rings 28 are filled with sealing rings 29 .

[0059] Specifically, when the upper end surface of the second air pipe 24 is fitted with the lower end surface of the first air pipe 23, two sets of connecting rings 28 are used to connect the fitting parts together, and sealing rings 29 are filled in the two sets of connecting rings 28 to seal the connection parts, thereby avoiding air leakage at the fitting parts.

[0060] Further and optionally, the rotating sleeve 11 and the torsion bar 17 are rotatably connected to the clamping block 3 and the frame 5 respectively through bearings, and a handle strap is provided at the upper end of the torsion bar 17.

[0061] The rotating sleeve 11 and the torsion bar 17 are rotatably connected to the block 3 and the frame 5 respectively through bearings, so as to fix the torsion bar 17 and the rotating sleeve 11 without affecting their rotation; by providing a handle belt at the upper end of the torsion bar 17, it is convenient to apply torque to the torsion bar 17.

[0062] Further and optionally, the cross-section of the slide groove is convex-shaped, and both ends of the second connecting rod 20 are hinged to the frame body 5 and the slider 19 respectively.

[0063] Such arrangement enables the slider 19 to be driven to move when the impact force is transmitted to the second connecting rod 20 .

[0064] Further and optionally, a sealing sleeve is provided between the first piston 22 and the first air cavity, and between the second piston 26 and the second air cavity.

[0065] Specifically, by providing sealing sleeves between the first piston 22 and the first air cavity, and between the second piston 26 and the second air cavity, it helps to provide a tight sealing effect and prevent gas from leaking from the gap between the first piston 22 and the inner wall of the first air cavity, and between the second piston 26 and the second air cavity.

[0066] Further and optionally, the cross-section of the connecting ring 28 is L-shaped, and two groups of the connecting rings 28 are fixedly connected to the inner walls of the first air pipe 23 and the second air pipe 24 respectively.

[0067] Specifically, the cross section of the connecting ring 28 is L-shaped, so that after the two sets of connecting rings 28 are attached, an annular groove for accommodating the sealing ring 29 is formed, thereby facilitating the installation of the sealing ring 29.

[0068] Further and optionally, the cross-section of the anti-collision strip 6 is semicircular.

[0069] Specifically, the structure of the anti-collision strip 6 can distribute the force on its curved surface, thereby improving the impact resistance.

[0070] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
