Specific embodiments
[0026] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Embodiment:
[0028] As Figures 1 to 6 shown, a ship hull anti-collision protection device includes a back plate 11 and an anti-collision block 5. Trapezoidal anti-collision blocks 5 are fixedly provided on both the left and right sides of the front surface of the back plate 11. A buffer protection component 7 is provided between the two groups of anti-collision blocks 5. Connecting rings 16 are fixedly provided at both the upper and lower ends of the buffer protection component 7. A chain 15 passes through the inside of the connecting ring 16, and both ends of the chain 15 are fixedly connected to the anti-collision block 5;
[0029] The buffer protection component 7 includes a flexible cylinder 71, exhaust holes 74 and buffer filler 75. The flexible cylinder 71 is arranged between the two groups of anti-collision blocks 5. The inside of the anti-collision block 5 is filled with buffer filler 75. Multiple groups of exhaust holes 74 are provided on the surface of the flexible cylinder 71. This design solves the problem that most of the existing ship hull anti-collision devices adopt simple fender structures, and their anti-collision effects are limited, especially it is difficult to effectively protect the ship hull during high-speed collisions.
[0030] In this embodiment, a flexible sheath 72 is provided at the outer spacer of the flexible cylinder 71, and a plurality of buffer plates 73 with a bent structure are fixedly provided between the flexible sheath 72 and the flexible cylinder 71, and the exhaust hole 74 is located in the inner area of the buffer plate 73. The flexible sheath 72, as an additional layer of protection, can further absorb and disperse the energy during the collision. The flexible sheath 72 not only increases the overall thickness of the buffer protection assembly 7, but also enhances the wear-resistant protection effect, effectively reducing the wear of the internal flexible cylinder 71. The buffer plate 73 further enhances the buffering capacity of the anti-collision device. When a collision occurs, the buffer plate 73 with a bent structure can be deformed to absorb and disperse the collision energy.
[0031] In this embodiment, the flexible cylinder 71, the flexible sheath 72, the anti-collision block 5 and the buffer plate 73 are all made of rubber material. The rubber material has good elasticity, wear resistance and impact resistance, and can deform when impacted, thereby absorbing and dispersing energy. The buffer filler 75 is made of foam material. The foam material is light, highly elastic, has good energy absorption and cushioning properties, and can quickly compress and absorb energy when impacted, thereby reducing the impact of the collision on the hull.
[0032] In this embodiment, the interiors of the two groups of anti-collision blocks 5 are both hollow structures, a water hose 3 is provided on the top of the left anti-collision block 5, the upper end of the water hose 3 is connected to the output end of the water pump 2, and the two groups of anti-collision blocks 5 are connected through a connecting pipe 12. This design can infuse water into the interior of the anti-collision block 5 through the water pump 2, and by injecting water into the interior of the anti-collision block 5, its weight and rigidity can be increased, thereby improving the anti-collision effect, and at the same time, the buffering performance of the anti-collision block 5 can be enhanced, and the impact energy can be better absorbed and dispersed during a collision, reducing the direct impact on the hull.
[0033] In this embodiment, a drain pipe 13 is connected to the top of the anti-collision block 5, and a valve 14 is installed at the outer end of the drain pipe 13. This design enables the anti-collision block 5 to discharge the internal water when it is hit, and prevents the anti-collision block 5 from being broken due to excessive squeezing force.
[0034] In this embodiment, a bottom plate 4 is arranged at intervals on the upper side of the back plate 11, and an electric winder 1 is installed on the bottom plate 4. A steel wire rope 8 is wound on the electric winder 1, and the lower end of the steel wire rope 8 passes through the bottom plate 4 and is connected to the back plate 11 through a lifting ring 9. This design facilitates the device to be fixedly connected to the ship through the bottom plate 4, and the steel wire rope 8 can be wound by the electric control of the electric winder 1, thereby driving the device as a whole to move up and down, which is convenient for adjusting the position of the anti-collision block 5 and the buffer protection component 7 on the hull, and can provide anti-collision protection for different positions of the hull.
[0035] In this embodiment, pulleys 10 are installed on the bottom plate 4, and the steel wire rope 8 bypasses the pulleys 10 and is connected to the back plate 11. The main function of the pulleys 10 is to reduce the friction between the steel wire rope 8 and the bottom plate 4 during the winding and unwinding processes. Through the smooth surface of the pulleys 10, the steel wire rope 8 can move more smoothly, thereby reducing the risk of wear and damage.
[0036] In this embodiment, multiple groups of ear plates 6 are fixedly provided on both the left and right sides of the back plate 11. The multiple groups of ear plates 6 provided facilitate the connection between devices, making it easy to connect multiple groups of this device, thereby forming a larger coverage area on the hull and improving the anti-collision protection effect.
[0037] The working principle of this ship anti-collision protection device: During actual use, first, the bottom plate 4 is fixed to the edge of the ship through bolts, and the back plate 11 is connected to the steel wire rope 8 through the lifting ring 9. By controlling the electric winch 1, the steel wire rope 8 can be wound and unwound, thereby driving the back plate 11 and the buffer protection assembly 7 and the anti-collision block 5 thereon to move up and down, and adjusting them to an appropriate position on the ship. Start the water pump 2, and fill the anti-collision block 5 with water through the water pump 2 to increase its weight and rigidity and improve the anti-collision effect. When the ship is collided, the anti-collision block 5 first contacts and absorbs part of the impact force. The trapezoidal design of the anti-collision block 5 increases the contact area, which helps to disperse the impact force. The flexible cylinder 71 and the flexible sheath 72 deform when impacted, further absorbing and dispersing energy. The buffer plate 73 bends under the collision pressure, increasing the buffering effect.
[0038] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
