Description

Technical Field

[0001] This utility model belongs to the field of water surface navigation mark technology, and in particular relates to a collision-proof water surface navigation mark. Background Technology

[0002] Surface navigation aids are specialized navigational aids placed on or in water to assist ships in navigation, positioning, and warning of dangerous areas. They serve as "visual signal towers" and "safety warning signs" for the maritime transportation system. The core function of surface navigation aids is to provide ship operators with clear information about the aquatic environment through standardized shapes, colors, lights, or signals, ensuring navigation safety and efficiency.

[0003] A search revealed a navigation mark with publication number CN207328759U published on the China Patent website. This navigation mark combines a buoy and a steel structure, reducing the volume of the buoy and lowering the overall cost while ensuring the buoy's buoyancy. However, it has some defects and shortcomings that need to be improved: (1) Most existing surface navigation marks lack anti-collision structures. When a ship traveling on the water collides with the navigation mark, the navigation mark is difficult to effectively decompose the impact force, making the overall structure of the navigation mark prone to deformation or even disintegration, thus causing it to malfunction; (2) Most existing surface navigation marks are usually equipped with There are navigation lights to assist navigation at night or in bad weather (fog, rain) through light signals. However, navigation lights often lack effective protection. When birds flying over the water land on the navigation light, they can easily damage it, thus affecting the navigation effect. (3) Some existing water navigation marks generally use the weight of the anchor to offset the thrust of wind, waves and currents on the buoy, so as to ensure that the navigation mark is always at the preset navigation point. However, after the anchor is connected to the buoy through the anchor chain or anchor cable, it often lacks effective limiting measures, which makes the anchor chain or anchor cable easy to sway under the action of water current, thus affecting the stability of the center of gravity of the buoy. Therefore, in view of the above problems, the anti-collision water navigation mark provided by this utility model is of great significance. Utility Model Content

[0004] This invention provides a collision-resistant navigational aid for waterways. When a vessel collides with the buoy, it will first come into contact with the various buffer cylinders. Upon impact, the buffer cylinders rotate around a positioning rod. This rotation of the buffer cylinders prevents the buoy from receiving direct impact from the vessel, and further reduces the impact force on the buoy, preventing deformation or even disintegration of the overall structure. When the buffer cylinders are struck by a vessel, the buffer rings within the slots separate the cylinders from the vessel and effectively absorb the impact force, thus buffering and absorbing energy, reducing the direct impact force on the cylinders and extending their service life. The navigation light signal can assist navigation at night or in inclement weather (fog, rain). A top cover is installed directly above the navigation light to protect it from dust and rain. In addition, when birds flying over the water land on the navigation light, the top cover can effectively protect the navigation light from damage and affect its navigational assistance effect. The anchor can be attached to the fixing ring at the bottom of the buoy by anchor chain or anchor cable to fix the position of the buoy. The anchor chain or anchor cable can pass through the center of the limiting cylinder, which can effectively limit the anchor chain or anchor cable to prevent it from swaying under the action of water flow and affecting the stability of the buoy's center of gravity. In summary, the problems in the background technology are solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a collision-resistant water surface navigation mark, comprising a float, which is cylindrical, with a column fixedly connected to its top. A bracket is fixedly connected to the top of the column, and a lamp holder is installed on the top of the bracket. A navigation light is electrically connected to the lamp holder. Connecting rods are fixedly connected to both sides of the bracket, and solar panels are fixedly connected to the ends of the connecting rods. A fixing ring is fixedly connected to the center of the bottom of the float, and several positioning frames are fixedly connected to the top of the float. The positioning frames are L-shaped and have positioning holes on their tops. Several positioning seats are fixedly connected to the side walls of the float, and each positioning seat has a positioning groove on its top surface. A buffer component is provided between each positioning seat and the positioning frame.

[0007] The buffer assembly includes a buffer cylinder, which is circular and has a through hole at its center. A positioning rod is inserted into the through hole, and the positioning rod has an external thread and is threaded to a nut that mates with it.

[0008] Furthermore, the wall of the buffer cylinder is provided with a number of slots, the slots are annular slot structures, and each slot is provided with a buffer ring. The buffer ring is annular, its inner diameter is equal to the inner diameter of the slot, and the outer end face of the buffer ring is arc-shaped.

[0009] Furthermore, the number of positioning rods and positioning seats is the same, and they are all distributed in an equidistant ring along the circumference of the float. The positioning groove is circular, and its diameter and the diameter of the positioning hole are both equal to the diameter of the positioning rod. Each positioning groove is located directly below its corresponding positioning hole.

[0010] Furthermore, each of the positioning frames has a reinforcing rib fixedly connected to its lower top surface. The reinforcing rib is triangular in shape, with one side of it fixedly connected to the side wall of the positioning frame.

[0011] Furthermore, a top cover is provided directly above the navigation light. The top end face of the top cover is spherical, and its area is larger than that of the light base and the navigation light. Several support rods are fixedly connected between the bottom of the top cover and the top of the bracket.

[0012] Furthermore, a limiting cylinder is provided directly below the fixing ring. The limiting cylinder is circular, and several fixing rods are fixedly connected to its wall. The fixing rods are L-shaped, and their other ends are fixedly connected to the bottom of the float. The fixing rods are distributed in an equidistant ring along the circumference of the limiting cylinder.

[0013] The present invention has the following advantages over the prior art:

[0014] (1) It can decompose the impact force from the ship and has a good anti-collision effect: When the ship traveling on the water surface collides with the navigation mark, it will first come into contact with each buffer cylinder. After being hit, the buffer cylinder will rotate around the positioning rod. At this time, the navigation mark can avoid being directly impacted by the ship through each buffer cylinder. Furthermore, the rotation of each buffer cylinder can dissipate some of the impact force, so as to further reduce the impact force on the navigation mark and prevent the overall structure of the navigation mark from deforming or even disintegrating. When the buffer cylinder is hit by the ship, the buffer ring in each slot can separate the buffer cylinder from the ship and fully absorb the impact force from the ship to play the role of buffering and energy absorption, thereby reducing the direct impact force on the buffer cylinder and extending its service life.

[0015] (2) It can protect the navigation light from damage by birds: The light signal of the navigation light can help navigation at night or in bad weather (fog, rain). A top cover is set directly above the navigation light to protect it from dust and rain. In addition, when birds flying over the water land on the navigation light, the top cover can effectively protect the navigation light to prevent birds from damaging the navigation light and affecting the navigation effect of the navigation light.

[0016] (3) The anchor chain or anchor cable connected to the anchor can be limited to ensure that the center of gravity stability of the float is not affected by the water flow: the anchor can be tied to the fixed ring at the bottom of the float by the anchor chain or anchor cable so as to fix the position of the float by the anchor. The anchor chain or anchor cable can pass through the center of the limiting tube. The limiting tube can effectively limit the anchor chain or anchor cable to prevent it from swaying under the action of the water flow and affecting the center of gravity stability of the float.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1-5 As shown, this utility model discloses a collision-resistant water surface navigation beacon, comprising a float 1, which is cylindrical, with a column 2 fixedly connected to its top. The float 1 is made of high-density polyethylene (PE) material, which provides buoyancy and supports the entire beacon to ensure it floats on the water surface. A bracket 3 is fixedly connected to the top of the column 2, and a lamp holder 4 is installed on the top of the bracket 3. A navigation light 5 is electrically connected to the lamp holder 4. The navigation light 5 can provide navigation assistance at night or in inclement weather (fog, rain) through light signals. Connecting rods 6 are fixedly connected to both sides of the bracket 3, and solar panels 7 are fixedly connected to the ends of the connecting rods 6. A lithium battery is installed inside the lamp holder 4 and is electrically connected to the solar panel 7 through wires. The solar panel 7 can absorb sunlight during the day and convert it into electrical energy, which is then stored in the lithium battery inside the lamp holder 4. At night or on cloudy or rainy days, the lithium battery can power the navigation light 5 to ensure uninterrupted signal (the range is typically ≥7 hours). (On cloudy or rainy days), solar power is a publicly available and mature technology, and its specific principle will not be elaborated here. A fixing ring 8 is fixedly connected to the bottom center of the float 1. Anchor chains or anchor cables can be attached to the fixing ring 8. An anchor (such as a concrete weight) is fixedly connected to the end of the anchor chain or anchor cable. The position of the float 1 can be fixed by the anchor to prevent the navigation mark from drifting due to wind, waves and water currents. Several positioning frames 9 are fixedly connected to the top of the float 1. The positioning frames 9 are L-shaped and have positioning holes 10 on their top. Several positioning seats 11 are fixedly connected to the side wall of the float 1. Each positioning seat 11 has a positioning groove 12 on its top surface, and a buffer component is provided between each positioning seat 11 and the positioning frame 9.

[0029] The buffer assembly includes a buffer cylinder 13, which is circular with a through hole 14 at its center. A positioning rod 15 is inserted into the through hole 14. The positioning rod 15 has an external thread and is threaded to a nut 16 that mates with it. The positioning rod 15 allows each buffer cylinder 13 to be installed between each positioning seat 11 and positioning frame 9. The buffer cylinder 13 can rotate around the positioning rod 15. When a ship traveling on the water accidentally collides with the navigation beacon, it will first come into contact with each buffer cylinder 13. After being impacted, the buffer cylinder 13 will rotate around the positioning rod 15. At this time, the buffer cylinder 13 can prevent the navigation beacon from being directly impacted by the ship. Furthermore, the rotation of each buffer cylinder 13 can dissipate part of the impact force, thereby further reducing the impact force on the navigation beacon and preventing the overall structure of the navigation beacon from deforming or even disintegrating. Specifically, the number of positioning frames 9, positioning seats 11, and buffer assemblies is set to six, and the central angle between adjacent buffer assemblies is 60°, ensuring that the ship can contact the buffer cylinder 13 when it impacts from any direction, thereby achieving all-round force dissipation.

[0030] The buffer cylinder 13 has several slots 17 on its wall. Each slot 17 is an annular groove structure, and each slot 17 contains a buffer ring 18. The buffer ring 18 is annular, and its inner diameter corresponds to the inner diameter of the slot 17. The outer end face of the buffer ring 18 is arc-shaped. The buffer ring 18 can be fitted into each slot 17 and adheres to the inner wall of the slot 17 for fixation by snap-fit. The buffer ring 18 is made of methyl vinyl silicone with a Shore hardness of 50-70HA, an elastic modulus of 0.8-1.2MPa, and an elongation at break of ≥300%, ensuring that it can absorb more than 60% of the impact force during impact. When the buffer cylinder 13 is hit by a ship, the buffer rings 18 in each slot 17 can separate the buffer cylinder 13 from the ship and fully absorb the impact force from the ship, thereby playing a role in buffering and absorbing energy, reducing the direct impact force on the buffer cylinder 13, and extending its service life.

[0031] The number of positioning rods 15 and positioning seats 11 is the same, and they are all distributed in an equidistant ring along the circumference of the float 1. The positioning grooves 12 are circular, and their diameters and the diameters of the positioning holes 10 are equal to the diameters of the positioning rods 15. Each positioning groove 12 is located directly below its corresponding positioning hole 10. After the positioning rod 15 passes through the positioning hole 10 and the through hole 14 in the center of the buffer cylinder 13, its bottom end can be inserted into and fit against the inner wall of the corresponding positioning groove 12. At this time, the nut 16 is threaded onto the positioning rod 15 and tightened to fix the position of the positioning rod 15 and the buffer cylinder 13. After use, the positioning rod 15, together with the buffer cylinder 13, can be removed from between the positioning frames 9 and the positioning seats 11 by unscrewing the nut 16, so as to perform regular maintenance and replacement of the buffer assembly. Specifically, the gap between the through hole 14 and the positioning rod 15 is 0.5-1mm to ensure that the buffer cylinder 13 can rotate flexibly around the positioning rod 15. The length of the positioning rod 15 is 8mm longer than the sum of the height of the positioning frame 9 and the height of the buffer cylinder 13. The part of the top of the positioning rod 15 that extends beyond the positioning frame 9 is machined with an external thread (M10). After the nut 16 is tightened, the distance between it and the top surface of the positioning frame 9 is ≥5mm to avoid obstructing the rotation of the buffer cylinder 13.

[0032] Each positioning frame 9 has a reinforcing rib 19 fixedly connected to its lower top surface. The reinforcing rib 19 is triangular, with one side fixedly connected to the side wall of the positioning frame 9. The reinforcing rib 19 can strengthen the structure of the positioning frame 9, thereby improving the structural strength of the positioning frame 9 and preventing it from deforming after being subjected to force for a long time, which would affect the installation and operation of the buffer assembly.

[0033] The navigation light 5 is equipped with a top cover 20. The top end of the top cover 20 is spherical and its area is larger than that of the light base 4 and the navigation light 5. Several support rods 21 are fixedly connected between the bottom of the top cover 20 and the top of the bracket 3. The top cover 20 can cover the navigation light 5 to prevent dust and rain. In addition, when birds flying over the water land on the navigation light, the top cover 20 can effectively protect the navigation light 5 to prevent the birds from damaging the navigation light 5 and affecting the navigation aid effect.

[0034] The limiting cylinder 22 is located directly below the fixing ring 8. The limiting cylinder 22 is circular, and several fixing rods 23 are fixedly connected to its wall. The fixing rods 23 are L-shaped, and their other ends are fixedly connected to the bottom of the float 1. The fixing rods 23 are distributed in a ring at equal intervals along the circumference of the limiting cylinder 22. When the anchor is connected to the fixing ring 8 through the anchor chain or anchor cable, the anchor chain or anchor cable can pass through the center of the limiting cylinder 22. At this time, the limiting cylinder 22 can effectively limit the anchor chain or anchor cable to prevent it from swaying under the action of water flow and affecting the stability of the center of gravity of the float 1. Specifically, the limiting cylinder 22 is a stainless steel cylinder with an inner diameter of 25-30mm (suitable for common anchor chains / anchor cables with a diameter of 8-10mm). The inner diameter is 2-5mm larger than the diameter of the anchor chain / anchor cable to ensure that the anchor chain / anchor cable can pass through smoothly without obvious swaying.

[0035] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0036] The working principle of this utility model is as follows:

[0037] In use, this invention allows for the attachment of an anchor chain or cable to the fixing ring 8 at the bottom of the float 1. The end of the anchor chain or cable is fixedly connected to an anchor (such as a concrete weight) to secure the position of the float 1. The anchor chain or cable passes through the center of the limiting cylinder 22, which effectively limits its movement to prevent it from swaying under water flow and affecting the stability of the float 1's center of gravity. When a vessel collides with a navigation beacon, it will first come into contact with each buffer cylinder 13. After impact, the buffer cylinders 13 rotate around the positioning rod 15. This rotation of the buffer cylinders 13 prevents the navigation beacon from being directly impacted by the vessel, further reducing the impact force on the navigation beacon. To prevent deformation or even disintegration of the overall structure of the navigation beacon, when the buffer cylinder 13 is hit by a ship, the buffer rings 18 in each slot 17 can separate the buffer cylinder 13 from the ship and fully absorb the impact force from the ship, thereby reducing the direct impact force on the buffer cylinder 13 and extending its service life. The navigation beacon is equipped with a navigation light 5, which can play a navigational aid role at night or in bad weather (fog, rain) through light signals. A top cover 20 is set directly above the navigation light 5, which can cover the navigation light 5 to play a role in dust and rain protection. In addition, when birds flying over the water land on the navigation beacon, the top cover 20 can effectively protect the navigation light 5 to prevent birds from damaging the navigation light 5 and affecting the navigational aid effect of the navigation beacon.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
