Description

Technical Field

[0001] This invention relates to the field of ship guidance equipment accessories, specifically designing a navigation beacon with a protective layer. Background Technology

[0002] Navigational aids are markers used to indicate the direction, boundaries, and obstructions of a waterway. These include river crossing markers, shore markers, guide markers, transitional guide markers, bow and stern guide markers, flank markers, port and starboard navigation markers, position markers, flood markers, and bridge / culvert markers. They are artificial markers used to guide ships, locate themselves, and indicate obstructions and warnings. For example, CN105947120A, "An Emergency Small Navigational Aid," consists of an upper buoy and a lower buoy body. The upper buoy is filled with polyurethane foam, but due to thermal expansion and contraction, gaps can form between the foam and the outer shell, affecting its effectiveness. Furthermore, existing navigational aids often have multi-layered functional frames that are welded together and cannot be disassembled, making overall maintenance and replacement difficult. Some functional frames have solar panels, but these panels cannot always be directly exposed to sunlight, resulting in low utilization rates. Additionally, dust easily adheres to the solar panels due to sea breezes, reducing conversion efficiency. Therefore, it is crucial to develop a navigational aid with a protective layer that overcomes these shortcomings. Summary of the Invention

[0003] To solve at least one of the above-mentioned technical problems, the present invention provides a buoy with a protective layer, comprising a buoy body, the buoy body including a protective shell on the outer side, a buoy body filled with a buoyant in the cavity of the protective shell, and a high-density polyethylene protective layer between the outer surface of the buoyant and the inner wall of the protective shell. The buoyant is a polyurethane layer. The protective shell is a low-density polyethylene layer. It also includes a functional frame, the functional frame being connected to the top of the buoy body via a detachable structure. The detachable structure includes a first column fixed to the bottom of the functional frame, a first limiting ring integrally formed at the bottom of the first column, a connecting ring formed at the top of the buoy body, a snap-fit ​​track on the connecting ring, and an insertion track formed at the end of the snap-fit ​​track. The width of the insertion track is greater than the diameter of the first limiting ring, and the width of the snap-fit ​​track is less than the diameter of the first limiting ring. A spring-loaded structure that curves upwards along the rotation direction of the first column is fixed at the bottom of the insertion track, so that the first limiting ring is limited between the top of the spring-loaded structure and the inner wall of the insertion track. The spring-loaded structure is wavy.

[0004] Through the above technical solution, the present invention allows the functional frame to be disassembled and connected via a detachable structure during installation, so as to replace and install different functional structures, and facilitate disassembly for maintenance and repair of the functional structures.

[0005] When put into use, the first limiting ring rotates into the snap-fit ​​track after being inserted into the track. The first limiting ring is limited between the top of the spring sheet structure and the inner wall of the insertion track, which facilitates the snap-fit ​​and fixation of the two. Since the spring sheet structure is wavy, it can increase elasticity and limiting effect.

[0006] A first recess is formed on the outer wall of the float, and a first protrusion that mates with the first recess is formed on the inner wall of the high-density polyethylene protective layer. A second recess facing the float is formed on the outer wall of the high-density polyethylene protective layer, and a second protrusion that mates with the second recess is formed on the inner wall of the protective shell. A third recess facing the high-density polyethylene protective layer is formed on the outer wall of the protective shell.

[0007] The first protrusion and the second recess are matched to ensure that the thickness of the high-density polyethylene protective layer remains consistent; the second protrusion and the third recess are matched to ensure that the thickness of the protective shell remains consistent.

[0008] The float comprises a first boss, a cylinder, and a second boss connected sequentially from top to bottom. The diameter of the first boss is smaller than the diameter of the cylinder. The second boss comprises several truncated cones with different angles, and the diameter of the second boss decreases from top to bottom. The high-density polyethylene protective layer and the protective shell are shaped to fit the float. A first connector is provided between the sidewall of the first boss and the upper surface of the cylinder, and the first connector has a first mounting hole. A second connector is provided around the second boss, and the second connector has a second mounting hole.

[0009] The functional frame includes a first support, which is positioned above the buoy body. The first support is equipped with markings and lighting, and a solar panel assembly is mounted on the outer wall of the first support.

[0010] The solar panel assembly includes a track plate fixed on a first bracket, a first gear rotatably connected to the track plate, a first circular track formed on the track plate outside the first gear, a second triangular track connected to the first circular track and the first circular track being tangent to the second triangular track, a second flip gear, a first slider and a second slider fixed on the second flip gear located on the first circular track or the second triangular track, a solar panel fixed on the second flip gear, and a flip control structure. A flip groove is formed on one side of the second triangular track. The flip control structure includes a rocker arm shaft connected to the flip groove. A spring is provided between the bottom of the first end of the rocker arm and the flip groove. When no external force is applied, the first end of the rocker arm blocks the second triangular track. When the first slider or the second slider compresses the spring, the second end of the rocker arm tilts upward, blocking the second triangular track, so that the second slider or the first slider enters the first circular track. A blocking block is fixed to the first end of the rocker, and an oblique or arc-shaped guide block is fixed to the second end of the rocker.

[0011] The second reversing gear has three parts, which are evenly distributed at 120 degrees.

[0012] Through the above technical solution, the first slider and the second slider of the present invention move simultaneously within the second triangular track. Subsequently, the first slider continues to enter the second triangular track, but the first slider lifts the second end of the rocker, which blocks the passage of the second slider to the second triangular track. Then, the second slider enters the first circular track according to the guide block, realizing the flipping. Through the above technical solution, when the present invention is not in use, or in cloudy or dark weather, the photovoltaic panel can face inward to prevent sea wind erosion. When the photovoltaic panel faces outward, the angle can be adjusted according to different directions of sunlight.

[0013] The functional frame also includes a second support, which is connected between the first support and the buoy body. The second support has a built-in battery. The first support and the second support are bolted together, and the second support is bolted to the buoy body.

[0014] It also includes a battery shock absorption structure, which includes a clamp with a spring sheet fixed to its inner wall. The surface of the spring sheet abuts against the surface of the battery. Bolt mounting holes are provided at both ends of the clamp. The battery shock absorption structure also includes a shock absorption spring, which includes an outer spring and an inner spring. The bottom of the inner spring is integrally formed with the bottom of the outer spring, and the diameter of the inner spring decreases from bottom to top. After the bolt passes through the bolt mounting hole, the shock absorption spring is sleeved and fixed to the inner wall of the second bracket.

[0015] The first and second supports mentioned above are made of low-density polyethylene.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This invention has a simple structure; the protective shell is a low-density polyethylene layer, which has good flexibility, extensibility, electrical insulation, and a certain degree of air permeability. It also exhibits good chemical stability, resistance to alkalis, and resistance to common organic solvents. This invention provides a high-density polyethylene protective layer between the outer surface of the float and the inner wall of the protective shell. This layer has strong tensile and creep resistance, low permeability to water vapor and air, and low water absorption, allowing it to adapt to the thermal expansion and contraction of the polyurethane float.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection claimed by the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention.

[0020] Referring to the accompanying drawings, the present invention adopts the following technical solution: a navigation buoy with a protective layer, comprising a buoy body, the buoy body including a protective shell 1 located on the outer side, a float 2 filled in the receiving cavity of the protective shell 1, and a high-density polyethylene protective layer 3 disposed between the outer surface of the float 2 and the inner wall of the protective shell 1. The float 2 is a polyurethane layer. The protective shell 1 is a low-density polyethylene layer.

[0021] A first recess 201 is formed on the outer wall of the float 2, and a first protrusion 301 that mates with the first recess 201 is provided on the inner wall of the high-density polyethylene protective layer 3. A second recess 302 facing the float 2 is formed on the outer wall of the high-density polyethylene protective layer 3, and a second protrusion 101 that mates with the second recess 302 is formed on the inner wall of the protective shell 1. A third recess 102 facing the high-density polyethylene protective layer 3 is formed on the outer wall of the protective shell 1.

[0022] It also includes a functional frame, which is connected to the top of the buoy body via a detachable structure. The detachable structure includes a first column 901 fixed to the bottom of the functional frame. A first limiting ring 902 is integrally formed at the bottom of the first column 901. A connecting ring 903 is formed at the top of the buoy body. A snap-fit ​​track 904 is provided on the connecting ring 903. An insertion track 905 is formed at the end of the snap-fit ​​track 904. The width of the insertion track 905 is greater than the diameter of the first limiting ring 902, and the width of the snap-fit ​​track 904 is less than the diameter of the first limiting ring 902. A spring sheet structure 906 that curves upward along the rotation direction of the first column 901 is fixed at the bottom of the insertion track 905 so that the first limiting ring 902 is limited between the top of the spring sheet structure 906 and the inner wall of the insertion track 905. The spring sheet structure 906 is wavy.

[0023] It is worth mentioning that, in such Figure 8 In this design, a limiting recess can be provided downward at the end of the spring sheet structure 906, and a limiting protrusion that mates with the limiting recess can be fixed downward at the bottom of the first limiting ring 902 to prevent them from dislodging when they are rotated into the locking position. It is worth mentioning that, in order to facilitate a secure locking position, a downward limiting recess 907 is provided on the convex part of the wavy spring sheet structure.

[0024] Through the above technical solution, the present invention allows the functional frame to be disassembled and connected via a detachable structure during installation, so as to replace and install different functional structures, and facilitate disassembly for maintenance and repair of the functional structures.

[0025] When put into use, the first limiting ring 902 rotates into the snap-fit ​​track 904 after being inserted into the insertion track 905. The first limiting ring 902 is limited between the top of the spring sheet structure 906 and the inner wall of the insertion track 905, which facilitates the snap-fit ​​and fixation of the two. Since the spring sheet structure 906 is wavy, it can increase elasticity and limiting effect.

[0026] The first protrusion 301 and the second recess 302 are matched to ensure that the thickness of the high-density polyethylene protective layer 3 remains consistent; the second protrusion 101 and the third recess 102 are matched to ensure that the thickness of the protective shell 1 remains consistent.

[0027] The float 2 includes a first boss 401, a cylinder 402, and a second boss 403 connected sequentially from top to bottom. The diameter of the first boss 401 is smaller than the diameter of the cylinder 402. The second boss 403 includes several frustums with different inclinations. The diameter of the second boss 403 decreases from top to bottom. The high-density polyethylene protective layer 3 and the protective shell 1 are shaped to match the float 2.

[0028] The above settings can increase the contact area between the three components, thereby increasing stability.

[0029] A first connector 5 is provided between the side wall of the first boss 401 and the upper surface of the cylinder 402, and a first mounting hole 501 is provided on the first connector 5; a second connector 6 is provided on the periphery of the second boss 403, and a second mounting hole 601 is provided on the second connector 6.

[0030] The functional frame also includes a first support 7, which is located above the buoy body. The first support 7 is equipped with an indicator 702 and a lighting lamp 701, and a solar panel assembly 703 is provided on the outer wall of the first support 7.

[0031] The solar panel 1008 assembly includes a track plate 1001 fixed on the top of a second support, i.e., the track plate is set below the first support. The track plate is connected to the first support through a connecting frame. The connecting frame is set to ensure a safe distance during the solar panel rotation adjustment process to prevent collisions. A first gear 1002 is rotatably connected in the track plate 1001. In this embodiment, the connecting frame passes through the track plate to connect the top of the second support and the top of the first support. A through hole is opened in the center of the first gear for the connecting frame to pass through. The first gear can be driven by fixing a drive motor on the connecting frame, and fixing a drive gear that meshes with the first gear at the output end of the drive motor.

[0032] A first circular track 1003 is formed on the track plate 1001 outside the first gear 1002, and a second triangular track 1004 is also provided. The second triangular track 1004 is connected to the first circular track 1003 and the first circular track 1003 is tangent to the second triangular track 1004. A second flip gear 1005 is also provided, on which a first slider 1006 and a second slider 1007 located on the first circular track 1003 or the second triangular track 1004 are fixed. A solar panel 1008 is fixed on the second flip gear 1005. A flip control structure is also provided. The structure includes a flipping groove 1009 on one side of the second triangular track 1004. The flipping control structure includes a rocker plate 1010 shaft-connected to the flipping groove 1009. A spring 1011 is provided between the bottom of the first end of the rocker plate 1010 and the flipping groove 1009. When no external force is applied, the first end of the rocker plate 1010 blocks the second triangular track 1004. When the first slider 1006 or the second slider 1007 compresses the spring 1011, the second end of the rocker plate 1010 tilts upward and blocks the second triangular track, so that the second slider 1007 or the first slider 1006 can enter the first circular track 1003.

[0033] A blocking block is fixed to the first end of the rocker 1010, and an oblique or arc-shaped guide block 1012 is fixed to the second end of the rocker 1010.

[0034] The second reversing gear 1005 has three parts, evenly distributed at 120-degree intervals. Limiting protrusions are formed on the inner walls of the top ends of the first circular track 1003 and the second triangular track 1004. Limiting grooves that cooperate with the limiting protrusions are formed on the first slider 1006 and the second slider 1007. These grooves cooperate to prevent the first slider 1006 and the second slider 1007 from sliding out of the tracks. The first slider 1006 and the second slider 1007 are spherical, meaning their contact portions with the first circular track 1003 and the second circular track are arc-shaped and tangent, reducing friction to a certain extent. A motor is fixed to the first bracket via a support, and the motor controls the rotation of the first gear 1002.

[0035] Through the above technical solution, the first slider 1006 and the second slider 1007 of the present invention move simultaneously within the second triangular track 1004. Subsequently, the first slider 1006 continues to enter the second triangular track 1004, but the first slider 1006 lifts the second end of the rocker 1010, which blocks the passage of the second slider 1007 to the second triangular track 1004. Then, the second slider 1007 enters the first circular track 1003 according to the guide block 1012, realizing the flipping. Through the above technical solution, when the present invention is not in use, or in cloudy or dark weather, the photovoltaic panel can face inward to prevent sea wind erosion, and when the photovoltaic panel faces outward, the angle can be adjusted according to different directions of sunlight.

[0036] The sides of the solar panel and the connecting frame do not contact each other, meaning that the solar panels do not touch each other during rotation.

[0037] A spherical protrusion 1013 is fixed to the top of the solar panel 1008. In this embodiment, a guide rail is provided downward at the top of the first bracket, and the spherical protrusion 1013 is installed on the guide rail. The bracket includes a top plate 1014, and a connecting column is welded between the bottom of the first bracket and the top plate 1014. The solar panel 1008 moves between the bottom of the first bracket and the top plate 1014.

[0038] The track plate 1001 can be circular, but in this embodiment it is triangular.

[0039] The functional frame also includes a second support 8, which is connected between the first support 7 and the buoy body. The second support 8 has a built-in battery. The first support 7 and the second support 8 are bolted together, and the second support 8 is bolted to the buoy body.

[0040] It also includes a battery shock absorption structure, which includes a clamp with a spring sheet fixed to the inner wall of the clamp. The surface of the spring sheet abuts against the surface of the battery. Bolt mounting holes are opened at both ends of the clamp. The battery shock absorption structure also includes a shock absorption spring 1011, which includes an outer spring 1101 and an inner spring 1102. The bottom of the inner spring 1102 is integrally formed with the bottom of the outer spring 1101, and the diameter of the inner spring 1102 decreases from bottom to top. After the bolt passes through the bolt mounting hole, the shock absorption spring 1011 is sleeved and fixed to the inner wall of the second bracket.

[0041] The first support 7 and the second support 8 mentioned above are made of low-density polyethylene.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a simple structure. The protective shell 1 is a low-density polyethylene layer, which has good flexibility, extensibility, electrical insulation, and a certain degree of air permeability. It also has good chemical stability and is resistant to alkalis and common organic solvents. The present invention provides a high-density polyethylene protective layer 3 between the outer surface of the float 2 and the inner wall of the protective shell 1. This layer has strong tensile and creep resistance, low permeability to water vapor and air, and low water absorption, and can adapt to the thermal expansion and contraction of the polyurethane float 2.

[0043] The above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
