Description

Technical Field

[0001] This invention belongs to the field of light posts, specifically relating to a high-strength protective light post for waterways. Background Technology

[0002] Light beacons, also known as "light markers," are fixed navigational beacons with a columnar or trapezoidal iron frame structure topped with a light emitter. They are typically placed on islands, shorelines, or in shallow water near waterways, or at the ends of breakwaters, and their light range is generally short. They are used for ship positioning or as azimuth markers to indicate dangerous areas, and can also be stacked for navigation.

[0003] Existing light posts typically consist of a post and a top platform. The post is usually made up of a bracket and a metal cylinder welded to the outer perimeter of the bracket, while the top platform is fixed above the post so that signal lights can be installed on the top platform for illumination and indication.

[0004] In addition, the pillars are usually painted with pigments, resulting in a red and white striped coating on the outer circumference of the metal cylinder to make the light post more eye-catching. However, since the light posts are often used in environments such as islands and shorelines, the paint on the surface of the metal cylinder is prone to fading, thus affecting the light post's visibility. To solve the problem of fading on the outer circumference of the pillars, one possible improvement is to replace the metal cylinder with a plastic sleeve. Using a plastic sleeve with a specific color injection molding process instead of the painted metal cylinder can prevent fading. However, since the plastic sleeve is usually installed on the bracket with bolts, its installation strength is much lower than that of the welded metal cylinder, and the pressure-bearing capacity of the plastic sleeve is also lower than that of the metal cylinder. Therefore, in severe wind conditions (especially during typhoons), the plastic sleeve is very prone to pressure damage or detachment. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high-strength protective light post for waterways that can be controlled to connect the inside and outside of the light post to reduce the pressure on the plastic sleeve in strong winds and thus provide protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a column and a top platform are included, the top platform being positioned above the column.

[0019] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection of 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. Conventional choices and substitutions made by those skilled in the art under the guidance of the present invention should be considered within the scope of protection of the present invention.

[0020] like Figures 1-20 As shown, the present invention discloses a high-strength protective light beacon for waterways, comprising a column 1 and a top platform 2, wherein the top platform 2 is disposed above the column 1.

[0021] Specifically, in this embodiment, the column 1 includes a bracket 3 and several plastic sleeves 4. Each plastic sleeve 4 includes an inner mounting base 41 and an outer rotating base 42. Each inner mounting base 41 is arranged in a ring and surrounds the outer periphery of the bracket 3, and is fixedly installed with the bracket 3. Each outer rotating base 42 is arranged in a ring and surrounds the outer periphery of the corresponding inner mounting base 41, and is rotatably installed with the inner mounting base 41 in a circumferential manner. Each inner mounting base 41 has several first wind-resistant openings 411 (4 in this embodiment) arranged at equal intervals in a circumferential direction, and each inner mounting base 41 has a first sealing cover between adjacent first wind-resistant openings 411. The plate 412, each of the outer rotating seats 42 is provided with a plurality of second wind-resistant openings 421 (4 in this embodiment) arranged at equal intervals along the circumference, and each of the outer rotating seats 42 is provided with a second sealing cover plate 422 between adjacent second wind-resistant openings 421; the first wind-resistant opening 411 and the second sealing cover plate 422 are aligned, and the second wind-resistant opening 421 and the first sealing cover plate 412 are aligned to separate the inside of the bracket 3 from the outer periphery of the outer rotating seat 42, and the first wind-resistant opening 411 and the second wind-resistant opening 421 and the first sealing cover plate 412 and the second sealing cover plate 422 are aligned to connect the inside of the bracket 3 with the outer periphery of the outer rotating seat 42.

[0022] Therefore, 1. The plastic sleeves 4 are manufactured using plastic injection molding, so that vertically adjacent plastic sleeves 4 are arranged in alternating red and white patterns to enhance the visibility of the light post and prevent fading. 2. Under normal circumstances, the outer rotating seat 42 is rotated to align the first wind-resistant opening 411 with the second closed cover plate 422 and the second wind-resistant opening 421 with the first closed cover plate 412, so that the first wind-resistant opening 411 and the second wind-resistant opening 421 are completely covered. Therefore, from the appearance, each plastic sleeve 4 appears as a complete column to achieve the best visibility effect. 3. In strong wind conditions, the outer rotating seat 42 is rotated to ensure that the first wind-resistant opening 411 and the second wind-resistant opening 421 are completely covered. Therefore, from the appearance, each plastic sleeve 4 appears as a complete column to achieve the best visibility effect. The seat 42 rotates to align the first wind-resistant opening 411 with the second wind-resistant opening 421 and the first sealing cover 412 with the second sealing cover 422, so that the first wind-resistant opening 411 and the second wind-resistant opening 421 are connected. Therefore, most of the wind force enters the bracket 3 through the first wind-resistant opening 411 and the second wind-resistant opening 421, and then blows out through the space inside the bracket 3 and from the other first wind-resistant opening 411 and the second wind-resistant opening 421. The area of ​​the strong wind acting on the plastic sleeve 4 will be greatly reduced, so as to prevent the plastic sleeve 4 from being damaged or falling off due to excessive pressure, thus protecting the plastic sleeve 4 and ensuring the stable installation and use of the plastic sleeve 4.

[0023] In addition, each of the inner mounting bases 41 in this embodiment is provided with a climbing ladder 5 on its front side. Each climbing ladder 5 includes a ladder frame 51 and a guardrail 52. Each ladder frame 51 is fixedly installed on the inner mounting base 41, and each ladder frame 51 is arranged with a plurality of steps 53 at vertical intervals along the outer periphery of the corresponding outer rotating base 42. Each guardrail 52 includes a plurality of U-shaped rings 521, connectors 522, and positioning fasteners 523. Each U-shaped ring 521 is located on the side of the ladder frame 51 away from the inner mounting base 41 and is arranged at vertical intervals. The two ends of each U-shaped ring 521 are respectively hinged to the left and right sides of the ladder frame 51 so that the U-shaped ring 521 can be flipped up and down. Each connector 522 hinges the corresponding U-shaped rings 521 so that the corresponding U-shaped rings 521 flip synchronously. Specifically, the connector 522 is in the form of multiple vertical rods and cylindrical sleeves on the upper and lower sides of the rods. The U-shaped ring 521 is inserted through the cylindrical sleeve to achieve a hinge. In addition, each of the positioning fasteners 523 is connected to at least one U-shaped ring 521, and each of the outer rotating seats 42 is provided with a positioning fastener groove 423 on its outer periphery. When the first wind-resistant opening 411 is aligned with the second closed cover plate 422 and the second wind-resistant opening 421 is aligned with the first closed cover plate 412, the positioning fastener groove 423 is located on the movement trajectory of the positioning fastener 523, and the positioning fastener 523 moves into the positioning fastener groove 423 and abuts against the outer rotating seat 42 to position the guardrail 52. When the first wind-resistant opening 411 is aligned with the second wind-resistant opening 421 and the first closed cover plate 412 is aligned with the second closed cover plate 422, the second wind-resistant opening 421 is located on the movement trajectory of the positioning fastener 523, and neither the inner mounting seat 41 nor the outer rotating seat 42 is located on the movement trajectory of the positioning fastener 523.

[0024] Therefore, 1. When the first wind-resistant opening 411 is aligned with the second closed cover plate 422 and the second wind-resistant opening 421 is aligned with the first closed cover plate 412, that is, under normal use, the guardrail 52 is positioned by the positioning fastener 523 moving into the positioning fastener groove 423 and abutting against the outer rotating seat 42, so that the guardrail 52 is in a supported state. Figure 2 The lower half of the railing 52 allows the user to climb between the railing 52 and the ladder 51 to reach the top platform 2 for operation. In addition, the positioning buckle groove 423 and the positioning buckle 523 have the same circumferential limiting effect on the outer rotating seat 42 to prevent the outer rotating seat 42 from opening. 2. When the first wind-resistant opening 411 is aligned with the second wind-resistant opening 421 and the first closing cover 412 is aligned with the second closing cover 422, that is, in strong wind conditions, since the positioning buckle 523 is not supported by the contact between the inner mounting seat 41 and the outer rotating seat 42, the railing 52 will flip downward under the action of gravity. Figure 2 The upper half of the platform 2 is used to eliminate the space between the guardrail 52 and the ladder 51, making climbing impossible and thus preventing people from being in danger when climbing the top platform 2 in strong winds.

[0025] Preferably, in this embodiment, each of the positioning fasteners 523 is elongated, and there are four U-shaped rings 521. The positioning fasteners 523 are hinged to the two middle U-shaped rings 521. In addition, the U-shaped rings 521 are provided with a first hinge position 5211 that is hinged to the ladder frame 51 and a second hinge position 5212 that is hinged to the positioning fasteners 523. The second hinge position 5212 is located below the side of the corresponding first hinge position 5211 that is horizontally facing the outer rotating seat 42. Each of the positioning fasteners 523 is provided with a vertically extending abutting surface 5231 on the side facing the corresponding outer rotating seat 42.

[0026] Therefore, by hinged positioning fastener 523 to two U-shaped rings 521, the planar abutting surface 5231 abuts against the outer rotating seat 42, thereby improving the stability of positioning and preventing the positioning fastener 523 from coming off due to insufficient depth of the positioning fastener groove 423, thus failing to effectively position the guardrail 52. Since the second hinge position 5212 is located below the side of the corresponding first hinge position 5211 that is horizontally facing the outer rotating seat 42, after the abutting surface 5231 abuts against the outer rotating part, the U-shaped ring 521 will flip downwards, causing the abutting surface 5231 to flip towards the outer rotating part, thereby increasing the interaction force and ensuring the stability of the abutment.

[0027] Specifically, in this embodiment, the bracket 3 includes support rods 31 located on both sides of the inner mounting base 41 along the circumferential direction of each first wind-resistant opening 411. Each support rod 31 abuts against the inner circumference of the inner mounting base 41 so that the support rod 31 provides support when the inner mounting base 41 is subjected to force on the outside of the inner mounting base 41. Each plastic sleeve 4 is provided with an inner pressure plate 6 corresponding to each first closed cover 412. Each inner pressure plate 6 is located on the radial inner side of the corresponding first closed cover 412 along the inner mounting base 41, and each inner pressure plate 6 abuts against the corresponding two support rods 31 on both sides of the inner mounting base 41 along the radial inner side of the bracket 3, so that the inner pressure plate 6 replaces the first closed cover to bear the force on the inner side of the inner mounting base 41 and transmits the force to the support rods 31.

[0028] Therefore, 1. When the inner mounting base 41 is subjected to force on the outside, the support rod 31 provides support by pressing against the inner circumference of the inner mounting base 41, making the inner mounting base 41 more resistant to external force. 2. The strong wind entering the inner side of the bracket 3 cannot act on the first closed cover 412 under the action of the inner bearing plate 6. Therefore, the wind force acting on the inner mounting base 41 is smaller, which protects the inner mounting base 41. In addition, the force acting on the inner bearing plate 6 is transmitted to the support rod 31 by pressing against the inner bearing plate 6, which increases the bearing capacity of the inner bearing plate 6.

[0029] Preferably, in this embodiment, each of the inner bearing plates 6 has a plurality of mounting holes 61 extending radially through the inner mounting base 41. Each of the first closed cover plates 412 is provided with mounting screw holes 413 corresponding to each mounting hole 61, so that bolts are inserted through the mounting holes 61 and threadedly connected to the mounting screw holes 413 to fix the inner bearing plate 6, support rod 31, and inner mounting base 41. The upper and lower ends of each of the inner bearing plates 6 are respectively provided with circumferential positioning parts 62 that abut against the two support rods 31 along the circumference of the inner mounting base 41, thereby achieving a stable connection between the inner bearing plate 6, support rod 31, and inner mounting base 41.

[0030] Furthermore, in this embodiment, the number of brackets 3 corresponds to the number of plastic sleeves 4, and each bracket 3 is arranged vertically, so that different combinations of brackets 3 and plastic sleeves 4 can be selected according to needs to build light posts of different heights.

[0031] Specifically, each of the brackets 3 in this embodiment further includes an upper bracket ring 32 and a lower bracket ring 33. The two ends of each support rod 31 are respectively welded to the corresponding upper bracket ring 32 and lower bracket ring 33. Two upper folding rods 71 ​​and two lower folding rods 72 are provided between adjacent brackets 3. Each upper bracket ring 32 has an upper through hole 321 through its radial sides, and each lower bracket ring 33 has a lower through hole 331 through its radial sides. The through direction of the upper through hole 321 is the same as that of the lower through hole 331. The insertion directions are perpendicular to each other. Each upper folding rod 71 includes an upper middle section 711 and upper insertion sections 712 located at both ends of the upper middle section 711. Each lower folding rod 72 includes a lower middle section 721 and lower insertion sections 722 located at both ends of the lower middle section 721. Each upper insertion section 712 is inserted with a corresponding upper through hole 321, and each lower insertion section 722 is inserted with a corresponding lower through hole 331. The upper middle section 711 is located above the lower middle section 721, and the two abut against each other to perform axial positioning of adjacent brackets 3.

[0032] Therefore, when two adjacent brackets 3 are spliced, the upper folding rod 71 and the lower folding rod 72 are first arranged in a mesh shape so that the upper middle section 711 and the lower middle section 721 abut against each other. Then, each upper insertion section 712 is inserted into the corresponding upper through hole 321 (horizontal movement is possible, and disassembly is the same). Each lower insertion section 722 is inserted into the corresponding lower through hole 331 (horizontal movement is possible, and disassembly is the same) to achieve vertical limiting connection between the upper frame ring 32 and the lower frame ring 33 of the adjacent brackets 3. The vertical limiting strength is provided by the mesh upper folding rod 71 and the lower folding rod 72 abutting against each other, resulting in greater strength.

[0033] Furthermore, in this embodiment, adjacent brackets 3 are provided with mounting components 8 corresponding to each upper folding rod 71 and each lower folding rod 72. Each mounting component 8 includes a mounting bolt 81, a mounting nut 82, and a threaded seat 83. The upper frame ring 32 and the lower frame ring 33 have C-shaped cross-sections with the opening facing radially outward. The upper frame ring 32 is provided with a first through hole 84 vertically through each upper folding rod 71 and each lower folding rod 72, and the lower frame ring 33 is provided with a first through hole 84 vertically through each upper folding rod 71 and each lower folding rod 72. A second through hole 85 is provided, and each upper folding rod 71 and each lower folding rod 72 is provided with a third through hole 86 through it vertically. Each threaded seat 83 corresponding to the upper folding rod 71 is provided in the lower frame ring 33, and each threaded seat 83 corresponding to the lower folding rod 72 is provided in the upper frame ring 32. The mounting bolt 81 passes through the first through hole 84, the second through hole 85, and the third through hole 86 respectively, and is threadedly connected to the corresponding mounting nut 82 and threaded seat 83. The head of the mounting bolt 81 is located above the corresponding first through hole 84.

[0034] Therefore, 1. The mounting bolt 81 is inserted through the first through hole 84, the second through hole 85, and the third through hole 86 and cooperates with the mounting nut 82 to limit the connection of the upper frame ring 32, the lower frame ring 33, the upper folding rod 71, and the lower folding rod 72. 2. The setting of the nut seat not only supports the gap between the C-shaped upper frame ring 32 or the lower frame ring 33, making the vertical bearing effect better, but also cooperates with the mounting bolt 81 to prevent the mounting bolt 81 from loosening and losing its installation force when the mounting nut 82 loosens and falls, which would cause the lamp post to collapse (at this time, the upper folding rod 71 and the lower folding rod 72 provide axial limiting force, and the mounting bolt 81 mainly provides radial and circumferential limiting function). 3. The head of the mounting bolt 81 is on the upper side to prevent the mounting bolt 81 from falling off.

[0035] Preferably, in this embodiment, each inner mounting base 41 includes two horizontally separated inner bases 414, which are fixedly connected by bolts. Each outer rotating base 42 includes two horizontally separated outer bases 424. The outer periphery of each inner base 414 is provided with a semi-circular guide groove 415, and the two guide grooves 415 on the corresponding two inner bases 414 are spliced ​​to form a ring. The inner periphery of each outer base 424 is provided with a semi-circular guide rail 425, which cooperates with the guide groove 415 to realize the sliding installation of each outer base 424 on the inner mounting base 41. This allows the inner mounting base 41 to be installed and removed horizontally by the separated inner bases 414. The outer bases 424 are similarly arranged, making the installation and removal of the plastic sleeve 4 more convenient.
