Description

Technical Field

[0001] This utility model relates to the field of ship technology, and more specifically, to a collision protection structure for inland waterway vessels. Background Technology

[0002] Inland waterway vessels are a type of vessel that navigates inland rivers, lakes, reservoirs, and other waterways. They are primarily used for inland waterway travel and generally do not travel at sea. Inland waterway vessels navigating in different navigation areas have different requirements for stability and anti-sinking properties.

[0003] For example, the ship's side collision protection structure disclosed in authorization announcement number CN219790481U allows the tires to be suspended on the ship's side at the bow position by setting three ring straps on each tire. The ring straps allow the tires to sway slightly, and can be squeezed and deflected during a collision to buffer the impact.

[0004] In the above-mentioned method, the tires are fixed to the ship's side by a ring-shaped strap. The left and right straps cross and connect adjacent tires, which will cause some straps to be subjected to shear force during a collision, making them prone to breakage or wear, thereby reducing the service life of the anti-collision structure. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a more durable anti-collision structure for inland waterway vessels.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A collision avoidance structure for an inland waterway vessel includes a vessel body with multiple threaded mounting holes symmetrically arranged on both sides of the vessel body, each threaded mounting hole being connected to a collision avoidance component.

[0008] The anti-collision assembly includes a support frame that is threaded to the ship body. The end of the support frame is provided with a connection hole corresponding to the threaded mounting hole, and a fastening rod is inserted into the connection hole.

[0009] Symmetrical guide tracks are provided on both sides of the connecting hole, and anti-collision balls are connected to each guide track by hinges.

[0010] Two sets of vertical connecting rods are symmetrically hinged on the outer surface of the anti-collision ball. One end of the vertical connecting rod extends into the guide slide to form a sliding fit. The two sets of vertical connecting rods are distributed in a mirror symmetrical manner along the vertical center line of the anti-collision ball.

[0011] Multiple sets of elastic support arms are distributed circumferentially on the outer side of the support frame. Each elastic support arm is connected to a guide plate at its end, and the outer surface of the guide plate is formed with a wave-shaped structure.

[0012] The present invention is further configured such that: the supporting frame adopts a composite layered structure, including an inner pressure plate, an outer protective plate and a sandwich reinforcement structure, wherein the sandwich reinforcement structure is composed of multiple hexagonal reinforcing ribs arranged in a honeycomb array, and the two ends of each hexagonal reinforcing rib are welded and fixed to the inner pressure plate and the outer protective plate respectively.

[0013] The present invention is further configured such that: a rubber ball is embedded inside the cavity of the hexagonal reinforcing rib, and the surface of the rubber ball is provided with a matrix-distributed air-permeable microporous structure.

[0014] The present invention is further configured such that: the fastening rod adopts a segmented rod structure, including a threaded fastening section that mates with the threaded mounting hole and a smooth positioning section that mates with the connection hole.

[0015] The present invention is further configured such that: the elastic support arm is made of high-damping rubber composite material, and its cross-sectional dimensions are gradually reduced along the direction of the guide plate.

[0016] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0017] The detachable anti-collision components on both sides of the hull allow for flexible adaptation to different collision scenarios and facilitate rapid replacement of damaged parts. The honeycomb-patterned hexagonal reinforcing ribs within the anti-collision components, combined with internally perforated rubber balls, absorb energy through deformation and mitigate impact through airflow, providing dual protection for the hull. The ingenious combination of the anti-collision balls and sliding linkages achieves multi-angle collision buffering, while the outer corrugated guide vanes effectively disperse water flow impact and collision energy. Specially designed threaded fastening rods and elastic support rods ensure overall structural stability and further dissipate collision kinetic energy through their elastic deformation. The entire system achieves both high anti-collision performance and lightweight design, significantly improving the navigation safety and structural durability of inland waterway vessels.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Working principle: During use, the construction personnel first clean the threaded mounting holes 2 reserved on both sides of the ship body 1, align the connecting holes 5 of the support frame 4 with the threaded mounting holes 2, and then insert the fastening rod 6 so that the threaded fastening section 16 of the fastening rod 6 engages and fixes with the threaded mounting hole 2, thereby achieving precise positioning of the support frame 4. When the hull encounters a collision, the wave-shaped groove of the outer guide plate 11 first disperses the impact force laterally, and the elastic support arm 10 then bends and deforms to absorb part of the kinetic energy; under severe impact, the anti-collision ball 8 drives the vertical connecting rods 9 on both sides to slide and unfold along the slide, buffering the collision force at different angles through multi-directional rotation. At the same time, the hexagonal reinforcing ribs 14 of the honeycomb structure inside the support frame 4 are deformed under pressure, and the internal rubber ball 15 is squeezed and air is discharged through the vent hole to achieve flexible buffering. After the collision, each component automatically resets due to the elasticity of the material.

[0025] like Figures 1 to 3 As shown,

[0026] The anti-collision structure 3 of the inland waterway vessel includes the vessel body 1. Multiple threaded mounting holes 2 are symmetrically opened on both sides of the vessel body 1. Each threaded mounting hole 2 is connected to an anti-collision component, which protects the vessel body 1.

[0027] The anti-collision component includes a support frame 4 that is threadedly connected to the ship body 1. The support frame 4 adopts a composite layered structure, including an inner pressure plate 12, an outer protective plate 13, and a sandwich reinforcement structure. The sandwich reinforcement structure is composed of multiple hexagonal reinforcing ribs 14 arranged in a honeycomb array. The two ends of each hexagonal reinforcing rib 14 are welded and fixed to the inner pressure plate 12 and the outer protective plate 13, respectively. The honeycomb sandwich reinforcement structure makes the structural strength of the support frame 4 higher.

[0028] The cavity of the hexagonal reinforcing rib 14 is fitted with a rubber ball 15. The surface of the rubber ball 15 has a matrix-distributed breathable microporous structure, which can absorb energy through deformation and reduce impact through air flow when impacted.

[0029] The end of the support frame 4 is provided with a connection hole 5 corresponding to the threaded mounting hole 2. A fastening rod 6 is inserted into the connection hole 5. The fastening rod adopts a segmented rod structure, including a threaded fastening section 16 that mates with the threaded mounting hole 2 and a smooth positioning section 17 that is clearance-fitted with the connection hole 5. While fixing the support frame 4 to the ship body 1, the smooth positioning section 17 will not affect the support frame 4, thus avoiding friction between the fastening rod 6 and the inner wall of the connection hole 5, which could cause scratches.

[0030] The connecting hole 5 has symmetrical guide slides 7 on both sides. Each guide slide 7 is connected to an anti-collision ball 8 by a hinge. The ingenious combination of the anti-collision ball 8 and the sliding link realizes multi-angle collision buffering.

[0031] Two sets of vertical connecting rods 9 are symmetrically hinged on the outer surface of the anti-collision ball 8. One end of the vertical connecting rod 9 extends into the guide slide 7 to form a sliding fit. The two sets of vertical connecting rods 9 are distributed in a mirror symmetrical manner along the vertical center line of the anti-collision ball 8, which facilitates buffering when the anti-collision ball 8 is subjected to force.

[0032] Multiple sets of elastic support arms 10 are distributed circumferentially on the outer side of the support frame 4. The elastic support arms 10 are made of high-damping rubber composite material, and their cross-sectional dimensions are gradually reduced along the direction of the guide plate 11.

[0033] Each elastic support arm 10 is connected to a guide plate 11 at its end. The outer surface of the guide plate 11 is formed with a wave-shaped structure, which can effectively disperse the impact force and collision energy of the water flow.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
