Description

Technical Field

[0001] This utility model relates to the field of anti-collision technology, specifically an anti-collision device for marine vessels. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation capable of navigating or anchoring on water for transport or operations. Different vessels have different technical specifications, equipment, and structural forms depending on their intended use. A ship is a man-made means of transportation that primarily operates in geographical waters. Furthermore, civilian ships are generally called boats, military ships are called warships, and small boats are called vessels or dinghies; collectively, they are referred to as ships or dinghies.

[0003] When a ship docks, its own inertia causes it to collide with the shore. Because the structures on the shore are very hard, this can easily damage the ship's hull and affect its service life. Therefore, existing ships are equipped with anti-collision devices on their sides.

[0004] A search of patent document CN 220640190 U reveals a ship collision avoidance device. This device uses multiple sets of collision avoidance components to buffer impacts and achieve a protective effect. However, in use, the collision avoidance components of the prior art only form buffer support in the vertical direction. When an impact occurs, the buffer device is subjected to lateral forces generated by friction, making the vertically supported buffer device extremely prone to deformation and damage to the side under the action of lateral forces. Therefore, a new marine ship collision avoidance device is proposed to optimize the above-mentioned prior art. Utility Model Content

[0005] The purpose of this invention is to provide a marine vessel anti-collision device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A marine vessel anti-collision device includes an anti-collision structure comprising a transverse groove and a vertical groove. The transverse groove is fixedly connected to the vertical groove, and the transverse groove and the vertical groove are centered and perpendicular to each other. A first sliding block and a second sliding block are respectively provided at the upper and lower parts of the vertical groove. Two first support arms are rotatably connected to the second sliding block, and a second support arm is rotatably mounted on the first sliding block. The two first support arms are parallel to each other, and the second support arm is symmetrically arranged with the first support arm. The first support arm and the second support arm are of equal length, and their corresponding ends are rotatably connected to an abutment component. Two third sliding blocks are symmetrically arranged in the transverse groove, and a third support arm is rotatably mounted on each third sliding block. The ends of the third support arms are rotatably mounted on the sidewall of the abutment component.

[0008] As a further embodiment of this utility model: the abutting component includes a U-shaped groove, and a plurality of stacked guide rollers are provided on the inner side of the opening of the U-shaped groove. The stacking height of the guide rollers is adapted to the inner cavity height of the U-shaped groove. A first long bolt is provided through the U-shaped groove. The first long bolt passes through the plurality of guide rollers at the same time. A locking nut is threadedly connected to the threaded end of the first long bolt.

[0009] As a further embodiment of this invention: the first sliding block and the second sliding block are adapted to the vertical groove, and a first spring is provided on both sides of the first sliding block and the second sliding block within the vertical groove. The first spring between the first sliding block and the second sliding block is a single unit. A second long bolt passes through the vertical groove, and a nut is threaded to the threaded end of the second long bolt. The second long bolt slides through both the first sliding block and the second sliding block simultaneously, and also passes through the first spring.

[0010] As a further embodiment of this invention: the third sliding block is adapted to the transverse groove, and a second spring is provided on both sides of the third sliding block within the transverse groove, with the second springs between the third sliding blocks forming a single unit. A third long bolt passes through the transverse groove, and a nut is threaded to the threaded end of the third long bolt. The third long bolt slides through both third sliding blocks simultaneously and passes through the second spring.

[0011] As a further embodiment of this utility model: multiple anti-collision structures are provided, and each anti-collision structure is fixedly connected to a fixed base plate. The fixed base plate has mounting holes. The multiple anti-collision structures are staggered vertically at equal intervals. The vertical grooves are fixedly connected to the fixed base plate and are set at equal intervals. The horizontal grooves are staggered vertically and fit together with each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model forms vertical support in the vertical groove by using the first and second support arms in conjunction with the first and second sliding blocks, and forms lateral support in the horizontal groove by using the third support arm in conjunction with the third sliding block, thus forming four-sided support. It can provide elastic buffering from the sides when subjected to lateral friction force, effectively reducing the possibility of deformation and damage.

[0014] 2. In this invention, a guide roller is installed on the inner side of the U-shaped groove by a long rod bolt. In the event of an impact, the guide roller can form a sliding steering action, allowing the vessel to adjust its direction more quickly and escape the collision danger zone.

[0015] 3. This utility model uses a first spring to provide elastic support for the first and second sliding blocks, and a second spring to provide elastic support for the third sliding block. Thus, when an impact occurs, the first and second sliding blocks can compress the first spring, and the third sliding block can compress the second spring, thereby providing elastic buffering against the impact.

[0016] 4. In this utility model, the first sliding block, the second sliding block, and the first spring are assembled and installed in the vertical groove by the second long rod bolt, and the third sliding block and the second spring are assembled and installed in the horizontal groove by the third long rod bolt. The horizontal grooves are staggered and the vertical grooves are parallel to each other, which makes it easy to disassemble and install the first long rod bolt and the second long rod bolt, thus facilitating the replacement and maintenance of components when the device is damaged.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4In this embodiment of the present invention, a marine vessel anti-collision device includes an anti-collision structure 17, which includes a transverse groove 1 and a vertical groove 2. The transverse groove 1 is fixedly connected to the vertical groove 2. The transverse groove 1 and the vertical groove 2 are arranged vertically and centered on each other. The upper and lower parts of the vertical groove 2 are respectively provided with a first sliding block 3 and a second sliding block 4. Two first support arms 5 are rotatably connected to the second sliding block 4. A second support arm 6 is rotatably installed on the first sliding block 3. The two first support arms 5 are parallel to each other. The second support arm 6 is symmetrically arranged with the first support arm 5. The first support arm 6 and the second support arm 5 are of equal length. The corresponding ends of the first support arm 5 and the second support arm 6 are rotatably connected to an abutment component 7.

[0024] The first support arm 5 and the second support arm 6, together with the first sliding block 3 and the second sliding block 4, form vertical support in the vertical groove 2. The third support arm 9, together with the third sliding block 8, forms support on both sides in the horizontal groove 1, thus forming four-sided support. This allows for elastic buffering from the sides when subjected to lateral friction, effectively reducing the possibility of deformation and damage.

[0025] The abutment component 7 includes a U-shaped groove 10. Multiple stacked guide rollers 11 are provided inside the opening of the U-shaped groove 10.

A shaft hole for the first long bolt 12 to pass through is opened at the center of the guide roller 11. A circular hole for the first long bolt 12 to pass through is opened on the U-shaped groove 10.

[0026] Guide rollers 11 are installed on the inner side of the U-shaped groove 10 by long rod bolts 12, so that the guide rollers 11 can form a sliding steering action during the impact, and the ship can adjust its direction more quickly and get away from the collision danger zone.

[0027] The first sliding block 3 and the second sliding block 4 are adapted to the vertical groove 2. The first spring 13 is provided in the vertical groove 2 on both sides of the first sliding block 3 and the second sliding block 4.

[0029] The first spring 13 provides elastic support for the first sliding block 3 and the second sliding block 4, and the second spring 15 provides elastic support for the third sliding block 8. Thus, when an impact occurs, the first sliding block 3 and the second sliding block 4 can compress the first spring 13, and the third sliding block 8 can compress the second spring 15, thereby providing elastic buffering against the impact.

[0030] A second long bolt 14 passes through the vertical groove 2. A round hole is provided in the vertical groove 2 for the second long bolt 14 to pass through. A nut is threaded to the threaded end of the second long bolt 14. The second long bolt 14 slides through the first sliding block 3 and the second sliding block 4.

[0031] A third long bolt 16 passes through the transverse groove 1. A round hole is provided in the transverse groove 1 for the third long bolt 16 to pass through. A nut is threaded to the threaded end of the third long bolt 16. The third long bolt 16 slides through two third sliding blocks 8 at the same time. A round hole is provided in the third sliding block 8 for the third long bolt 16 to pass through and slide. The third long bolt 16 passes through the second spring 15.

[0032] The first sliding block 3, the second sliding block 4, and the first spring 13 are assembled in the vertical groove 2 by the second long rod bolt 14, and the third sliding block 8 and the second spring 15 are assembled in the horizontal groove 1 by the third long rod bolt 16. The horizontal grooves 1 are staggered and the vertical grooves 2 are parallel to each other, so that the first long rod bolt 14 and the second long rod bolt can be easily disassembled and installed, thus facilitating the replacement and maintenance of components when the device is damaged.

[0033] Multiple anti-collision structures 17 are provided, and all multiple anti-collision structures 17 are fixedly connected to the fixed base plate 18. The fixed base plate 18 is provided with mounting holes. The multiple anti-collision structures 17 are arranged at equal intervals and staggered vertically. The vertical groove 2 is fixedly connected to the fixed base plate 18 and is arranged at equal intervals. The horizontal groove 1 is staggered vertically and fits together with each other. The fixed base plate 18 is fixedly installed to the marine vessel through the mounting holes.

[0034] The first long rod bolt 12, the second long rod bolt 14, and the third long rod bolt 16 are all threaded at the ends, while the remaining rod sections are plain rods, which can provide rotational and sliding guidance.

[0035] The working principle of this utility model is as follows:

[0036] In use, the first spring 13 provides elastic support for the first sliding block 3 and the second sliding block 4, and the second spring 15 provides elastic support for the third sliding block 8. Thus, upon impact, the first sliding block 3 and the second sliding block 4 can compress the first spring 13, and the third sliding block 8 can compress the second spring 15, providing elastic cushioning against the impact.
