For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

The term "multiple" means two or more, unless otherwise clearly and specifically defined.

[0050] The ship lock protection structure provided by the present invention is now described. Figure 1 and Figure 2 The ship lock protection structure 1 includes a base frame 10, a support frame 20, a buffer device 30 and a plurality of energy absorbing panels 40, wherein the base frame 10 is fixed on a protected object, such as a lock chamber, a lock head, a gate and / or a pilot channel, the support frame 20 is arranged at intervals on one side of the base frame 10, and the buffer device 30 is arranged between the base frame 10 and the support frame 20, that is, the support frame 20 is connected to the base frame 10 through the buffer device 30, and the energy absorbing panel 40 is detachably connected to the support frame 20, and the plurality of energy absorbing panels 40 are respectively arranged at intervals in the longitudinal and transverse directions on the side of the support frame 20 away from the base frame 10.

[0051] Optionally, the buffer device 30 may be a spring buffer, a hydraulic buffer or a cement buffer commonly used in the art; a plurality of energy absorbing panels 40 may be arranged on the support frame 20 at equal intervals in the longitudinal and transverse directions. It is understood that the ship lock protection structure 1 provided by the present invention may be used in multiple fields such as dock berthing protection, elevator shaft impact protection, and rail vehicle impact protection in addition to ship lock protection.

[0052] When the ship lock is hit by a ship, if the impact force is small, the ship lock protection structure 1 can absorb the energy generated by the collision through the buffer device 30, thereby protecting the ship lock and the ship from damage. At this time, since the buffer device 30 has an automatic reset function, the ship lock protection structure 1 does not need to be repaired or replaced; if the impact force is large, when the buffer device 30 is compressed to the maximum threshold, the energy absorption panel 40 will undergo plastic deformation to absorb the remaining energy generated by the collision, thereby protecting the support frame 20, the buffer device 30 and the base frame 10 from damage. At this time, only the damaged energy absorption panel 40 needs to be repaired or replaced; if the energy generated by the collision exceeds the maximum threshold of the energy that the energy absorption panel 40 can absorb, the support frame 20 will undergo plastic deformation to absorb the remaining energy generated by the collision, thereby protecting the buffer device 30 and the base frame 10 from damage. At this time, the energy absorption panel 40 and the support frame 20 need to be repaired or replaced. In this way, most of the energy generated during the accidental collision can be absorbed, ensuring that the ship lock body is not damaged.

[0053] The ship lock protection structure 1 provided by the present invention adopts a support frame 20, a buffer device 30, an energy absorbing panel 40 and a base frame 10. The energy generated during the collision of the ship with the ship lock is absorbed by the three-level protection structure of the buffer device 30, the energy absorbing panel 40 and the support frame 20, thereby ensuring that the ship lock body is protected from damage. Moreover, since the energy absorbing panel 40 is detachably connected to the support frame 20, the energy absorbing panel 40 is easy to repair and replace, thereby effectively solving the technical problems of poor buffering efficiency and difficulty in repair of the ship lock protection structure, improving the impact resistance and service life of the ship lock protection structure, enhancing the safety of the ship lock, and reducing the maintenance cost of the ship lock.

Specifically, according to actual needs and the specific shape of the panel 41, the energy absorbing panel 40 may include one, two or more side panels, the side panels are arranged circumferentially along the edges of the panels 41, and are enclosed with the two symmetrically distributed panels 41 to form a receiving space, and the receiving space may be filled with one, two or more energy absorbing elements 42. When the energy absorbing panel 40 is collided, the panel 41 squeezes the side panels and the energy absorbing element 42, and the collision energy is absorbed by plastic deformation of the side panels and the energy absorbing element 42, thereby enhancing the buffering efficiency of the ship lock protection structure 1.

[0055] For further information, see Figures 3 to 5As a specific embodiment of the ship lock protection structure provided by the present invention, the energy absorbing panel 40 also includes a corrugated skin 43, which is fastened to the panel 41, and the corrugated skin 43 divides the above-mentioned accommodating space into a plurality of accommodating chambers 400, and the energy absorbing elements 42 are placed in the accommodating chambers 400. Specifically, the outer contour of the panel 41 is rectangular, that is, the panel 41 has four edges, and the corrugated skin 43 includes a main body 431 and two shielding parts 432, wherein the cross-sectional profile of the main body 431 is wavy, the outer surface of the main body 431 is bonded or welded to the inner surface of the panel 41, and the two shielding parts 432 are respectively warped outward from the opposite ends of the main body 431, bonded or welded to the two edges of the panel 41, and enclosed together with the two side panels and the two panels 41 to form a closed accommodating space, so that the corrugated skin 43 cooperates with the side panels to support The support panel 41 can effectively improve the ability of the energy absorbing panel 40 to resist vertical and lateral impacts, and enhance the stability of the structure of the energy absorbing panel 40; the main body 431 divides the accommodating space into a plurality of accommodating chambers 400, and each accommodating chamber 400 is filled with an energy absorbing element 42, so that when the energy absorbing panel 40 is collided, the corrugated skin 43 and the energy absorbing element 42 absorb the energy generated during the collision through their own plastic deformation, effectively protecting the support frame 20, the buffer device 30 and the base frame 10 from damage, thereby enhancing the buffering efficiency of the lock protection structure 1.

[0056] Optionally, as a specific embodiment of the lock protection structure provided by the present invention, the energy absorbing element 42 is a porous solid material piece, that is, the energy absorbing element 42 is made of porous solid materials such as aluminum foil honeycomb material, stainless steel foil honeycomb material, acrylic corrugated paper, foam aluminum, etc., so that the energy absorbing element 42 has the characteristics of light weight and good energy absorption effect, which is beneficial to reduce the overall weight of the lock protection structure and enhance the buffering efficiency of the lock protection structure 1. In addition, since the manufacturing technology of the energy absorbing element 42 made of porous solid material is mature and the cost is low, the maintenance cost of the lock protection structure 1 is reduced.

When the ship lock protection structure 1 is hit, the pressure plate 32 transmits the energy generated by the collision to the spring assembly 33. The spring assembly 33 converts the collision energy into internal energy or heat energy through its own compression or extension for absorption, thereby ensuring that all the collision energy is absorbed when the impact force is small, thereby protecting the ship lock protection structure 1 from damage caused by the collision.

Specifically, the outer contour of the bottom plate 311 is rectangular, the support plate 312 is convexly arranged on the side surface of the bottom plate 311 away from the base frame 10, and the length direction of the support plate 312 is parallel to the length direction of the bottom plate 311, two support plates 312, one end plate 313 and one end of the bottom plate 311 are surrounded to form a receiving groove, and the other two support plates 312, another end plate 313 and the other end of the bottom plate 311 are surrounded to form another receiving groove, and the two spring seats 331 and the two springs 333 are respectively accommodated in the two receiving grooves, and the opposite ends of the spring 333 can be respectively It is abutted against or welded with the spring seat 331 and the end plate 313, one end of the guide rod 332 is welded or integrally formed with the spring seat 331, the other end of the guide rod 332 passes through the spring 333 and the end plate 313 in sequence and is connected with a limit nut or a retaining spring, one end of the connecting shaft 334 is welded or integrally formed with the spring seat 331, the other end of the connecting shaft 334 passes through the end of the connecting arm 335 and extends into the guide hole 3120, and is slidably connected with the support plate 312 through a pulley or a bearing, that is, the other end of the connecting arm 335 is clamped between the spring seat 331 and the support plate 312.When the spring 333 is a compression spring and the pressure plate 32 is subjected to external force, the pressure plate 32 gradually approaches the bottom plate 311, and drives the four connecting arms 335 hinged on the opposite side edges of the pressure plate 32 to push the two spring seats 331 to move along the extension direction of the guide hole 3120, and gradually approach the two end plates 313.
