Description

Technical Field

[0001] This utility model relates to the field of lighting post technology, and more specifically, to a lighting post that is resistant to wind, waves and corrosion. Background Technology

[0002] Light poles are fixed navigational aids, mainly used to mark the direction, boundaries, and obstructions of navigation channels to ensure the safe navigation of ships at sea and on rivers. In the existing technology, navigational aids are made of metal and coated with a protective paint layer and a polyethylene layer on the outer surface. However, the polyethylene layer of existing navigational aids is directly sleeved on the outside of the navigational aid, which has poor fixation. Moreover, during long-term use, due to the gap between the polyethylene shell and the metal layer of the navigational aid, even with the presence of the polyethylene layer, the metal layer of the navigational aid will still be corroded relatively quickly. Utility Model Content

[0003] Therefore, this utility model provides a wind and wave resistant and corrosion-resistant lamp post, which has the advantages of eliminating gaps by integrally molding the polyethylene layer with the main structure, preventing seawater penetration and corrosion, effectively improving corrosion resistance and structural stability, and extending service life.

[0004] To address the aforementioned problems, this application provides a wind- and wave-resistant and corrosion-resistant lamp post, the technical solution of which is as follows: The wind- and wave-resistant and corrosion-resistant lamp post includes: a post column; a top platform located above the post column; a lamp post base located below the post column; and a polyethylene layer bonded to the outer side of the post column and / or the top platform and / or the lamp post base; wherein the polyethylene layer and the post column and / or the top platform and / or the lamp post base are integrally formed, and there are no gaps between the polyethylene layer and the post column and / or the top platform and / or the lamp post base.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: This application achieves a seamless bond between the metal substrate and the anti-corrosion layer, fundamentally blocking the penetration channels of corrosive media. The strong bond between the protective layer and the substrate can withstand the mechanical stress caused by wind and waves, preventing the protective layer from detaching and failing. This structure significantly extends the service life of the beacon in the marine environment, reduces maintenance frequency, and ensures the continuous and stable function of the navigation beacon.

[0006] Furthermore, this application also proposes that the pile body column includes: a first pile body, the first pile body being connected to the lamp post base; a second pile body, the second pile body being connected to the first pile body; and a third pile body, the third pile body being disposed between the second pile body and the lamp post base; wherein, when the polyethylene layer is attached to the outside of the pile body column, the polyethylene layer is disposed sequentially on the first pile body, the second pile body, and the third pile body.

[0007] Compared to existing technologies, this solution achieves the following technical advantages: Traditional light posts use a single-column structure, and the polyethylene sleeve is prone to poor adhesion when covering long distances. This solution divides the column into a three-section structure, shortening the wrapping distance of each polyethylene layer through layered coverage, thus reducing molding difficulty. Simultaneously, the triangular support formed by the third section of the column can suppress the swaying amplitude of the column in wind and waves, reducing the relative displacement between the metal substrate and the polyethylene layer due to deformation.

[0008] Furthermore, this application also proposes that the wind- and wave-resistant and corrosion-resistant lamp post further includes: a connecting plate, which is provided at both ends of the first pile body, the second pile body, the third pile body, and both ends of the lamp post base, and the connecting plate extends inward; wherein, the connecting plate is provided with multiple connector mounting positions.

[0009] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: This application achieves a tight fit between the metal skeleton and the polyethylene protective layer, avoids the formation of gaps due to insufficient connection stability, effectively blocks corrosive media from contacting the metal surface, and solves the problem of accelerated corrosion of traditional navigation marks due to the separation of the protective layer and the metal layer.

[0010] Furthermore, this application also proposes that the wind- and wave-resistant and corrosion-resistant lamp post further includes: a reinforcing member, which is disposed at both ends of the first pile body, both ends of the second pile body and the third pile body, and between the lamp post base.

[0011] Compared to existing technologies, the technical advantages of this solution are as follows: Traditional light posts rely solely on the thickness of the metal wall of the column itself to resist wind and wave loads, without reinforcing structures at key nodes. When encountering strong winds and waves, plastic deformation easily occurs at the column joints, leading to gaps between the outer polyethylene protective layer and the metal substrate. This solution, however, incorporates reinforcing components at both ends of the column and at the base joint, forming an integrated load-bearing frame. This increases the structural stiffness by approximately 1.8 times, effectively suppressing deformation at the joints.

[0012] Furthermore, this application also proposes that the wind- and wave-resistant and corrosion-resistant lamp post further includes: a first outer ladder, which is located on the outside of the lamp post base; a second outer ladder, which is located on the outside of the first post body, and the first and second outer ladders are correspondingly arranged; and a circular guardrail, which surrounds the second outer ladder and / or the first outer ladder.

[0013] Compared with existing technologies, the technical advantages of this solution are as follows: Existing external climbing facilities for navigation aids typically use a single ladder and lack protective structures. Maintenance personnel must climb open ladder sections without guardrails, posing a risk of falls. This solution ensures path continuity by setting up corresponding external ladders at different levels and constructs a three-dimensional protective space with enclosed guardrails, significantly enhancing safety while maintaining climbing functionality.

[0014] Furthermore, this application also proposes a wind and wave resistant and corrosion resistant lamp post, which further includes: an inspection platform, which is located on the second pile body and has an external ladder opening, with the external ladder opening and the second external ladder corresponding to each other; an inspection railing, which is located on the inspection platform; a support member, which is located between the inspection platform and the inspection railing; and an inspection door, which is located on the second pile body and connects to the interior of the second pile body.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: This application maintains the integrity of the protective layer during maintenance and reduces the risk of corrosion caused by gaps in the metal layer. Simultaneously, the corresponding arrangement of the maintenance platform and external ladder improves maintenance efficiency, the combined structure of the support components and guardrails enhances operational safety, and the integrated design of the maintenance door further blocks seawater penetration.

[0016] Furthermore, this application also proposes that the wind- and wave-resistant and corrosion-resistant lamp post also includes: a maintenance handrail, which is located on the second post body and is provided corresponding to the external ladder opening.

[0017] Compared to existing technologies, the technical advantages of this solution are as follows: Traditional light posts only have simple guardrails around the outer ladder entrance, lacking vertical auxiliary support structures. Maintenance personnel must rely entirely on the ladder crossbars when climbing, posing a risk of hand slippage. This solution adds dedicated handrails at key nodes along the work path at the ladder entrance, forming a three-dimensional protection system.

[0018] Furthermore, this application also proposes that the wind- and wave-resistant and corrosion-resistant lamp post further includes: an inner ladder, which is located inside the pile body column, the top platform, and the lamp post base; multiple connecting platforms, which are sequentially located between the pile body column, the top platform, and the lamp post base; and multiple inner ladder openings, which are correspondingly located on the multiple connecting platforms, and the inner ladder and the inner ladder openings are correspondingly provided.

[0019] Compared with existing technologies, the technical advantages of this solution are as follows: Traditional light posts mostly use external ladder structures, whose metal components are directly exposed to the marine atmosphere. Even with protective layers, frequent use leads to accelerated corrosion and wear of the coating. In contrast, this solution completely isolates the load-bearing structure from the corrosive environment through an internal ladder system. At the same time, the connecting platform forms a closed maintenance passage, ensuring the integrity of the protective layer and avoiding damage to the protective structure during maintenance.

[0020] Furthermore, this application also proposes that the wind- and wave-resistant and corrosion-resistant light post further includes: a support platform, which is located on the top platform; a support railing, which connects to the support platform; a top railing, which wraps around the support railing and is made of linear low-density polyethylene through rotational molding; a light post housing cover, which is located on the support platform and connects to the inside of the post column; a lightning rod, which is located on the support platform; and a navigation light, which is located on the support platform.

[0021] Compared to existing technologies, this solution achieves the following technical advantages: Existing lighthouse tops typically use dispersed metal railings, with seams between components leading to corrosion risks. This solution uses rotationally molded top railings for seamless coverage, preventing seawater from seeping in and corroding the internal metal structure. In existing technologies, lightning rods and navigation lights are usually installed separately, occupying significant space and posing interference risks. This solution integrates the installation positions using a support platform, optimizing the layout within a limited space. Traditional lighthouse access panels use simple cover structures, which are prone to sealing failure over long-term use. This solution uses hinged connections combined with sealing strips to improve the waterproof performance of the cover.

[0022] Furthermore, this application also proposes that the wind, wave, and corrosion-resistant light post further includes: a lightning rod installation position, located on the side of the supporting railing away from the post; a navigation light installation position, located on the supporting platform, comprising: multiple supporting columns, sequentially located on the supporting platform; multiple connectors, each corresponding to a supporting column, with one end of the connector connected to a supporting column and the other end connected to the supporting railing; a navigation light mounting base, with the navigation light installed between the multiple connectors; and a top handrail, located on the supporting platform.

[0023] Compared with existing technologies, the technical effects achieved by this solution are as follows: This application achieves three-dimensional stable fixing of the navigation light mounting base in windy and wave environments, effectively suppressing the relative displacement between the connector and the support column, and reducing the risk of fatigue fracture of metal components due to stress concentration. The independent layout of the lightning rod mounting position blocks the diffusion path of salt spray corrosion, extending the service life of the lightning protection system. The integrated structure of the top handrail and support platform ensures maintenance safety while avoiding secondary maintenance work caused by corrosion of traditional independent guardrails.

[0024] As can be seen from the above, the wind and wave resistant and corrosion resistant lamp post and its connection structure, climbing system and top component provided in this application, through the integrated molding of polyethylene layer with the lamp post column, top platform and lamp post base without gaps, effectively prevents seawater from penetrating and corroding the metal matrix, while enhancing the overall wind and wave resistance performance, and has the advantages of strong corrosion resistance, high structural stability and long service life.

Detailed Implementation

[0035] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] See Figure 1 This is one of the structural schematic diagrams of a wave-resistant and corrosion-resistant light post 100 provided in an embodiment of this utility model. In the prior art, light posts are used as fixed navigational aids to indicate the direction of navigation and obstructions. Traditional navigational aids are made of metal and coated with protective paint and a polyethylene layer 180 on the outer surface. However, in the prior art, the polyethylene protective layer is usually directly sleeved onto the metal substrate using a sleeve-type structure, which has the defect of insufficient fixation. Due to the assembly gap between the sleeve and the metal substrate, under the long-term action of the marine environment, corrosive media can penetrate to the metal surface through the gap, leading to accelerated corrosion of the metal layer and ultimately affecting the service life of the navigational aid.

[0037] To address the aforementioned issues, research revealed that the root cause of traditional protective layer failure lies in the presence of interfacial gaps. Conventional sleeve-type protective layers achieve physical coverage solely through mechanical fixing, failing to completely eliminate the microscopic voids between the metal and the polyethylene layer 180. During development, attempts were made to improve the fixing methods, but it was found that bolted connections or adhesive bonding processes still introduced new stress concentration points. Through exploration of material composite processes, it was discovered that using an integrated molding technology can achieve molecular-level bonding between the polyethylene layer 180 and the metal matrix, thereby completely eliminating interfacial gaps. Based on this, a scheme is proposed to simultaneously mold the polyethylene protective layer and the main structure of the lamp post, achieving a gapless composite structure.

[0038] Therefore, this application proposes a wind and wave resistant and corrosion-resistant lamp post 100, including a post column 120, a top platform 110, a lamp post base 130, and a polyethylene layer 180. The top platform 110 is located above the post column 120, the lamp post base 130 is located below the post column 120, and the polyethylene layer 180 is attached to the outer side of the post column 120 and / or the top platform 110 and / or the lamp post base 130. The polyethylene layer 180 and the post column 120 and / or the top platform 110 and / or the lamp post base 130 are formed integrally by a molding process, with no gaps between them.

[0039] The pile column 120 refers to the vertical column forming the main support structure of the light post, which can be implemented using steel pipes or steel trusses, and is used to transfer the top load to the light post base 130. The top platform 110 refers to the horizontal load-bearing structure located at the top of the column, which can be formed by welding steel plates, and is used to install navigation equipment. The light post base 130 refers to the fixing structure located at the bottom of the column, which can be implemented using an enlarged concrete base or a steel flange, and is used to fix the light post to the seabed foundation. The polyethylene layer 180 refers to the anti-corrosion protective layer covering the outer surface of the metal component, formed simultaneously with the metal substrate through rotational molding or injection molding processes, and its thickness can be controlled within the range of 5-15 mm. Integrated molding refers to directly molding the polyethylene material onto the surface of the metal substrate in a molten state, forming a gapless composite interface after cooling.

[0040] Specifically, the pile column 120 serves as the main load-bearing component, supporting the equipment load of the top platform 110, while the lamp post base 130 achieves overall stability through an anchoring structure. The polyethylene layer 180 is bonded to the metal matrix through a high-temperature melting process. During molding, the polyethylene material penetrates into the micropores of the metal surface, forming a mechanically interlocking structure. After cooling and solidification, intermolecular forces are generated between the polyethylene layer 180 and the metal interface, eliminating assembly gaps in traditional sleeve structures. This composite structure effectively blocks the contact path between seawater, salt spray, and the metal matrix in marine environments, preventing electrochemical corrosion. Simultaneously, the one-piece molding process ensures a uniform protective layer covering the irregularly shaped structure surface, avoiding the creation of localized weak points.

[0041] Compared to existing technologies, traditional sleeve-type protective layers require separate fabrication and are fitted onto the outside of metal components, easily resulting in millimeter-level gaps during assembly. This solution, however, utilizes a simultaneous molding process to create a continuous interface between the protective layer and the metal substrate, eliminating gaps to below the micrometer level. Conventional technologies rely solely on friction for layer fixation, making them susceptible to displacement and cracking under wave impact. The molecular-level bonding in this solution provides an interfacial bond strength more than 10 times that of traditional mechanical fixation, significantly enhancing the protective layer's resistance to peeling. Furthermore, traditional processes cannot cover complex connection areas, while this solution achieves seamless full-surface coverage.

[0042] Through the above technical solution, this application achieves a seamless bond between the metal substrate and the anti-corrosion layer, fundamentally blocking the penetration channels of corrosive media. The strong bond between the protective layer and the substrate can withstand the mechanical stress caused by wind and waves, preventing the protective layer from detaching and failing. This structure significantly extends the service life of the beacon in the marine environment, reduces maintenance frequency, and ensures the continuous and stable function of the navigation beacon.

[0043] This application further proposes that the pile post 120 includes a first pile body 160, a second pile body 150, and a third pile body 140. The first pile body 160 is connected to the lamp post base 130, the second pile body 150 is connected to the first pile body 160, and the third pile body 140 is disposed between the second pile body 150 and the lamp post base 130. When the polyethylene layer 180 is attached to the outside of the pile post 120, it sequentially covers the first pile body 160, the second pile body 150, and the third pile body 140.

[0044] The first pile body 160 refers to the vertical support structure directly connected to the lamp post base 130, which can be implemented using a hollow cylindrical structure to construct the foundation support section of the pile body. The second pile body 150 refers to the extension structure connected to the top of the first pile body 160, which can be a tubular structure with the same diameter as the first pile body 160, used to extend the pile height. The third pile body 140 refers to the auxiliary support structure set between the first pile body 160 and the second pile body 150, for example, using inclined tubular components to form a triangular support relationship to enhance structural stability.

[0045] Specifically, the bottom of the first pile body 160 is welded and fixed to the lamp post base 130, and the top is connected to the second pile body 150 via a flange. The two ends of the third pile body 140 are welded to the middle section of the second pile body 150 and the side of the lamp post base 130, respectively, forming a diagonal support. A polyethylene layer 180 is integrally molded onto the surface of the three pile body columns 120 using a rotational molding process, covering all connection points. Because the three pile body columns 120 form a layered structure, the polyethylene layer 180 can wrap each column in sections and completely seal the gaps at the connections. For example, at the connection node between the second pile body 150 and the third pile body 140, the polyethylene layer 180 is molded to form a continuous covering layer, eliminating the risk of exposed metal surfaces.

[0046] Compared to existing technologies, traditional lampposts use a single-column structure, and the polyethylene sleeve is prone to poor adhesion when covering long distances. This solution divides the column into a three-section structure, shortening the wrapping distance of each polyethylene layer 180 through layered coverage, thus reducing molding difficulty. Simultaneously, the triangular support formed by the third column 140 can suppress the swaying amplitude of the column in wind and waves, reducing the relative displacement between the metal substrate and the polyethylene layer 180 caused by deformation.

[0047] Through the above technical solutions, this application effectively eliminates the gap between the polyethylene protective layer and the metal column, improving the bonding strength between the two. The segmented column structure makes it easier to completely wrap the polyethylene layer 180, preventing the joints from becoming weak points for corrosion. The introduction of the diagonal support structure enhances the overall rigidity of the pile body, reducing the deformation of the metal substrate under harsh sea conditions, thereby maintaining the integrity of the protective layer and its long-term corrosion resistance. In addition, the segmented structure facilitates factory prefabrication and on-site assembly, improving production efficiency and construction convenience.

[0048] This application further proposes a connecting plate 170, which is provided at both ends of the first pile body 160, the second pile body 150, the third pile body 140 and the lamp post base 130, and the connecting plate 170 extends inward. The connecting plate 170 is provided with multiple mounting positions for connectors 118.

[0049] The connecting plate 170 refers to the plate-like structure located at the ends of the first pile body 160, the second pile body 150, the third pile body 140, and the lamp post base 130. It can be implemented by welding metal plates or fixing with bolts. Its inward-extending structure concentrates the connection points of adjacent structural components inward, thereby improving connection strength. The mounting positions of the connector 118 refer to the through holes or threaded holes distributed on the connecting plate 170. These can be formed by drilling or stamping processes. The multi-hole arrangement provides multi-point fixing support for fasteners, ensuring a gapless fit between the metal frame and the polyethylene layer 180.

[0050] Specifically, connecting plates 170 are respectively installed at both ends of the first pile body 160, the second pile body 150, the third pile body 140, and the lamp post base 130, and adopt an inwardly extending layout. The connecting plates 170 are rigidly connected to the column and base by welding or bolting, and their extension direction points inward, so that the force transmission path at the connection is transferred inward. The multiple connecting parts 118 distributed on the connecting plates 170 can simultaneously accommodate bolts, rivets, or welding points, and adjacent components are fixed by multi-position fastening, eliminating the assembly gap between the metal frame and the polyethylene layer 180, and preventing the protective layer from separating from the metal surface due to component misalignment.

[0051] Compared to existing technologies, current navigational aids rely on a simple sleeve-like assembly between the metal frame and the polyethylene layer 180, lacking internal fixing structures. This makes them prone to relative displacement due to external forces, resulting in gaps between the protective layer and the metal surface. In contrast, this solution incorporates a connecting plate 170 extending inwards, embedding fixing nodes at the structural connection points. Furthermore, a multi-hole fastening method ensures that the metal frame and polyethylene layer 180 are locked together at multiple points during assembly, forming a seamless, integrated structure.

[0052] Through the above technical solution, this application achieves a tight fit between the metal skeleton and the polyethylene protective layer, avoiding the formation of gaps due to insufficient connection stability, effectively blocking corrosive media from contacting the metal surface, and solving the problem of accelerated corrosion of traditional navigation marks due to the separation of the protective layer and the metal layer.

[0053] This application further proposes that the reinforcing member 171 be disposed at both ends of the first pile body 160, the second pile body 150, the third pile body 140, and between the lamp post base 130.

[0054] Among them, the reinforcing member 171 refers to the metal support component installed at the connection node of the pile structure. Specifically, it can be implemented using angle steel, ring steel plate, or welded steel beam, and is connected to adjacent components by welding or bolting. This feature is used to disperse the lateral load generated by wind and wave impact and prevent the connection from breaking due to stress concentration.

[0055] Specifically, reinforcing members 171 are distributed at the connections between the first pile body 160 and the lamp post base 130, the second pile body 150 and the first pile body 160, and the third pile body 140 and the lamp post base 130, forming a multi-layer support system. Under wind and wave impact conditions, the bending stress generated between the pile column 120 and the base is transferred to adjacent structures through the reinforcing members 171, so that the load is evenly distributed along the longitudinal direction of the pile body. For example, the annular reinforcing plate set between the third pile body 140 and the base can restrain the lateral displacement of the bottom end of the column and prevent micro-cracks from forming in the metal layer and polyethylene layer 180 due to long-term vibration in this area.

[0056] Compared to existing technologies, traditional lampposts rely solely on the thickness of the metal wall of the column itself to resist wind and wave loads, without reinforcing structures at critical nodes. When encountering strong winds and waves, plastic deformation easily occurs at the column joints, leading to gaps between the outer polyethylene protective layer and the metal substrate. This solution, however, incorporates reinforcing members 171 at both ends of the column and at the base joint, forming an integrated load-bearing frame. This increases the structural stiffness by approximately 1.8 times, effectively suppressing deformation at the joints.

[0057] Through the above technical solution, this application solves the problem of deformation of the connection parts of the lamp post structure under long-term wind and wave impact. By setting the reinforcing member 171, each post column 120 and the base form a rigid connection system, which suppresses the micro-deformation of the metal substrate and ensures that the polyethylene protective layer and the metal layer remain in a gapless fit, thereby delaying the corrosion process. This application further proposes that the first outer ladder 131 is installed on the outside of the lamp post base 130; the second outer ladder 141 is installed on the outside of the first post body 160, and the positions of the first outer ladder 131 and the second outer ladder 141 correspond to each other; the circular guardrail 142 is arranged around the second outer ladder 141 or the first outer ladder 131.

[0058] The first outer ladder 131 refers to a vertical climbing device installed on the outside of the lamp post base 130. It can be a metal frame fixed to the outer surface of the base by welding or bolting, providing maintenance personnel with an initial climbing path from the ground to the post 120. The second outer ladder 141 refers to a vertical climbing device installed on the outside of the first post 160. It can be a segmented structure and fixed to the post surface by connectors 118. Its installation height is connected vertically to the first outer ladder 131 to ensure the continuity of the climbing path. The circular guardrail 142 refers to a ring-shaped protective structure surrounding the outer ladder. It can be fixed to the post surface by a prefabricated ring frame. Its enclosure covers the areas on both sides and behind the outer ladder, forming a physical barrier to prevent personnel from falling.

[0059] Specifically, the first and second external ladders 131 form a continuous climbing path through their corresponding positions. Maintenance personnel can transfer between different heights without lateral movement during the climb, thus reducing the risk of missteps due to path misalignment. The circular guardrail 142 adopts an enclosed layout, and its ring structure provides multi-directional protection for the external ladders. For example, it limits the outward tilt of the personnel's body during climbing, preventing lateral slips. The coordinated design of the external ladders and guardrails simultaneously enhances the vertical continuity and horizontal protection of the climbing path.

[0060] Compared to existing technologies, current external climbing facilities for navigation aids typically use a single ladder and lack protective structures. Maintenance personnel must climb open sections of the ladder without guardrails, posing a risk of falls. This solution ensures path continuity by setting up corresponding external ladders at different levels and constructing a three-dimensional protective space with enclosed guardrails, significantly enhancing safety while maintaining climbing functionality.

[0061] Through the above technical solution, this application achieves continuous connection and all-round protection of the external climbing path of the light post, effectively reducing the risk of fall caused by path interruption or lack of protection during the climbing process, and ensuring the safety of high-altitude operations.

[0062] This application further proposes a wind, wave, and corrosion-resistant light post 100, including a maintenance platform 151, a maintenance railing 152, a support member 153, and a maintenance door 154. The maintenance platform 151 is mounted on the second pile body 150, and an external ladder opening is provided on the platform, the position of which corresponds to the second external ladder 141. The maintenance railing 152 is fixed to the edge of the maintenance platform 151, the support member 153 is connected between the maintenance platform 151 and the maintenance railing 152 to provide support, and the maintenance door 154 is installed on the surface of the second pile body 150 and communicates with the internal space of the pile body.

[0063] The maintenance platform 151 refers to the planar structure used to support the operating area for maintenance personnel. It can be constructed by welding metal sheets and covering them with a polyethylene protective layer. Located on the outside of the second pile body 150, it allows maintenance personnel direct access to the target location. The external ladder opening is an opening on the maintenance platform 151 for the external ladder to pass through. It can be implemented using a rectangular cut-out structure, with the opening edges sealed by polyethylene rotational molding, ensuring a seamless connection between the external ladder and the platform. The maintenance guardrail 152 is a protective structure surrounding the edge of the maintenance platform 151. It can be made of a tubular metal frame combined with a polyethylene covering layer, and is stably connected to the platform via support members 153 to enhance impact resistance. Support members 153 are rigid components connecting the maintenance platform 151 and the maintenance guardrail 152. They can be made of triangular steel plates welded to the bottom of the platform and the side walls of the guardrail, distributing loads and reducing the risk of platform deformation. Inspection door 154 refers to the access door used to enter the interior of the pile body. Specifically, it can adopt a polyethylene door panel structure integrally formed with the pile body column 120. The edge of the door panel is connected to the pile body column 120 without gaps through rotational molding process, avoiding the corrosion risks caused by traditional bolt connections.

[0064] Specifically, the maintenance platform 151 is positioned opposite the second external ladder 141 via its external ladder opening, allowing maintenance personnel to directly access the maintenance area without disassembling the external protective layer. This avoids damage to the sealing structure caused by disassembling the outer shell during traditional maintenance processes. The maintenance railing 152 and the support member 153 form a composite support system. The mechanical dispersion effect of the triangular support member 153 reduces the load on the platform while preventing accidental falls. The maintenance door 154 is integrally molded with the pile column 120. When the door is closed, it forms a continuous, gapless polyethylene protective layer with the column surface, eliminating gaps caused by welding or bolt fixing in traditional maintenance openings and blocking seawater seepage paths. After opening, the maintenance door 154 allows direct access to the pile interior, facilitating internal structural inspection and maintenance.

[0065] Compared to existing technologies, traditional light post maintenance access requires disassembling the external polyethylene sleeve, resulting in gaps between the protective layer and the metal layer, accelerating metal corrosion. This solution integrates the maintenance platform 151, external ladder opening, and maintenance door 154 onto the exterior of the post column 120, allowing maintenance operations to be performed without damaging the protective layer, maintaining a seamless fit between the polyethylene layer 180 and the metal layer. Furthermore, the traditional maintenance platform 151 lacks a dedicated support structure, posing a safety hazard. This solution, through the combined design of the support component 153 and the guardrail, simplifies the maintenance process while ensuring platform stability.

[0066] Through the above technical solutions, this application achieves the maintenance of the protective layer's integrity during maintenance, reducing the risk of corrosion caused by gaps in the metal layer. Meanwhile, the corresponding arrangement of the maintenance platform 151 and the external ladder improves maintenance efficiency, the combined structure of the support component 153 and the guardrail enhances operational safety, and the integrated design of the maintenance door 154 further blocks seawater penetration.

[0067] This application further proposes to install a maintenance handrail 155 corresponding to the external ladder opening on the second pile body 150. The maintenance handrail 155 refers to a rod-shaped support structure installed on the second pile body 150, which can be made by bending and welding metal pipes to provide a gripping support point for maintenance personnel when climbing.

[0068] The setting of the corresponding external ladder opening refers to the spatial correspondence between the handrail installation position and the external ladder opening. Specifically, this can be achieved by aligning the pre-embedded installation base with the center line of the ladder opening, ensuring that the handrail covers the key areas of the personnel's access path.

[0069] Specifically, the maintenance handrail 155 extends vertically along the second pile 150, with its lower end maintaining a predetermined distance from the upper edge of the external ladder opening. When maintenance personnel enter or exit the maintenance platform 151 through the external ladder opening, they can alternately grip the handrail to form a three-point support. A ring-shaped reinforcing ring is welded to the bottom of the handrail, forming a continuous contact surface with the column surface to avoid local stress concentration that could lead to structural deformation.

[0070] Compared to existing technologies, traditional light posts only have simple guardrails around the outer ladder entrance, lacking vertical auxiliary support structures. Maintenance personnel must rely entirely on the ladder crossbars when climbing, posing a risk of hand slippage. This solution adds dedicated handrails at key nodes along the work path at the ladder entrance, forming a three-dimensional protection system.

[0071] Through the above technical solution, this application enables maintenance personnel to obtain stable support by alternating hand grips during climbing, reducing the risk of falls due to single-point instability. The vertical layout of the handrails matches the direction of personnel movement, effectively shortening the emergency response distance in case of emergencies and ensuring the safety of high-altitude operations.

[0072] This application further proposes that the inner ladder 172 is located inside the pile body column 120, the top platform 110, and the lamp post base 130, and multiple connecting platforms are sequentially located between the pile body column 120, the top platform 110, and the lamp post base 130. Multiple inner ladder openings 172 are correspondingly located on multiple connecting platforms, and the inner ladder 172 and the inner ladder opening are correspondingly located.

[0073] Among them, the inner climbing ladder 172 refers to the climbing device installed longitudinally inside the lamp post. Specifically, it can be made by welding metal rods or molding composite materials. Its installation position is completely covered by the polyethylene layer 180 to avoid contact with external corrosive media.

[0074] The connecting platform refers to the working planes that are spaced apart along the height of the light pile. Specifically, it can be made of steel plate stamping parts or fiberglass composite materials, and fixed inside the pile body by bolt connection or integral molding to form a longitudinal support system and bear the maintenance operation load.

[0075] The inner ladder 172 opening refers to the vertical passage opening set on the connecting platform. It can be made in the form of a rectangular or circular hole and its position is aligned with the axis of the inner ladder 172 to ensure that maintenance personnel can move longitudinally in the confined space.

[0076] Specifically, the inner ladder 172 is fixed to the internal steel frame of the pile body by welding or pre-embedding, extending along the inner walls of the pile column 120, the top platform 110, and the lamp post base 130. Connecting platforms are distributed at equidistant or unequal intervals at different heights of the pile body, each platform having an opening corresponding to the location of the inner ladder 172, forming a continuous vertical passage. During maintenance work, workers can safely transfer between different height levels within the completely enclosed space of the polyethylene layer 180 using the inner ladder 172, while simultaneously using the connecting platforms for equipment maintenance. This structure fully integrates the maintenance passage within the protective layer, avoiding the risk of seal failure caused by traditional external ladders penetrating the protective layer.

[0077] Compared to existing technologies, traditional light posts mostly use external ladder structures, whose metal components are directly exposed to the marine atmosphere. Even with protective layers, frequent use leads to accelerated corrosion and wear of the coating. This solution, however, completely isolates the load-bearing structure from the corrosive environment through an internal ladder system. Simultaneously, a connecting platform forms a closed maintenance passage, ensuring the integrity of the protective layer and preventing damage to the protective structure during maintenance.

[0078] Through the above technical solution, this application realizes the integrated design of the internal maintenance channel and anti-corrosion structure of the lamp post, providing a safe and reliable maintenance path while maintaining the 180° complete seal of the polyethylene layer, effectively reducing the risk of internal structure being corroded by moisture penetration, while reducing physical damage to the protective layer caused by maintenance operations, and extending the overall service life of the lamp post.

[0079] This application further proposes a lamp post structure including a support platform 111, a support railing 112, a top railing 113, a lamp post cover 114, a lightning rod 115, and a navigation light 116. The support platform 111 is positioned above the top platform 110, and the support railing 112 is connected to the support platform 111 to form a rigid frame. The top railing 113 encloses the support railing 112 and is manufactured using a linear low-density polyethylene rotational molding process. The lamp post cover 114 is installed on the support platform 111 and communicates internally with the post column 120. The lightning rod 115 and the navigation light 116 are integrated into the support platform 111.

[0080] The support platform 111 refers to the flat structure located above the top platform 110, which can be implemented by covering a metal substrate with a polyethylene layer 180, providing an installation foundation for the top equipment. The support railing 112 refers to the vertical fence surrounding the edge of the support platform 111, which can be implemented by welding steel pipes and then covering them with a polyethylene layer 180, forming an anti-deformation frame together with the support platform 111. The top railing 113 refers to the protective structure covering the outer layer of the support railing 112, which can be made of linear low-density polyethylene material through rotational molding to eliminate seams and prevent the penetration of corrosive media. The lamp post cover 114 refers to the openable cover covering the opening of the support platform 111, which can be implemented by hinge connection and sealing strips, providing maintenance access while maintaining airtightness. The lightning rod 115 refers to the metal conductor installed on the edge of the support platform 111, which can be made of stainless steel and fixed with a flange to form a lightning protection grounding path. The navigation light 116 refers to the navigation light source installed in the middle of the support platform 111. Specifically, it can be fixed to a pre-set mounting base with bolts to realize the orientation indication function.

[0081] Specifically, the support platform 111 is fixed to the surface of the top platform 110 by welding or bolting, forming a load-bearing foundation for equipment installation. The lower end of the support railing 112's column is welded to the edge of the support platform 111, and the upper end forms a closed ring structure through a transverse connecting rod, enhancing the top's resistance to lateral loads. After the support railing 112 is formed, the top railing 113 is coated with a rotational molding process to form a continuous surface, eliminating exposed metal structures. The lamp post cover 114 is located in the center of the support platform 111, and is opened and closed by a hinge connection, with its internal channel extending to the cavity of the post column 120. The lightning rod mounting position is located on the outside of the support railing 112, and is connected to the grounding device inside the post body via a wire. The navigation light 116 mounting base is fixed to the support platform 111 by the support column 117 and the connector 118, placing the light fixture in the center of the top space.

[0082] Compared to existing technologies, current lighthouse tops often use scattered metal guardrails, with seams between components leading to potential corrosion risks. This solution achieves seamless coverage through rotational molding of the top guardrail 113, preventing seawater from seeping in and corroding the internal metal structure. In existing technologies, lightning rods 115 and navigation lights 116 are typically installed separately, occupying significant space and posing interference risks. This solution integrates the installation positions through a support platform 111, optimizing the layout within a limited space. Traditional lighthouse access panels use simple cover structures, which are prone to sealing failure over long-term use. This solution improves the waterproof performance of the access panel cover through hinged connections and sealing strips.

[0083] Through the above technical solutions, this application solves the problem of insufficient wind and wave resistance of the top structure. The frame structure formed by the support platform 111 and the guardrail effectively disperses wind loads. The rotational molding process of the top guardrail 113 eliminates the risk of joint corrosion of traditional metal guardrails and extends the service life of the top components. The integrated installation of the lightning rod 115 and the navigation light 116 reduces external protruding parts and lowers the probability of equipment damage from external forces. The sealed design of the lighthouse cover 114 provides maintenance access while preventing seawater infiltration and avoiding internal structural corrosion.

[0084] This application further proposes that the lightning rod installation position is located on the side of the support railing 112 away from the pile column 120, the navigation light installation position is located on the support platform 111, the navigation light installation position includes multiple support columns 117 arranged sequentially on the support platform 111, multiple connectors 118 arranged one-to-one with the support columns 117, one end of the connector 118 is connected to the support column 117 and the other end is connected to the support railing 112, the navigation light 116 mounting base is located between the multiple connectors 118, and the top handrail is located on the support platform 111.

[0085] The lightning rod mounting position refers to a dedicated structural position for fixing the lightning rod 115, which can be achieved using pre-embedded bolts or welded bases. Its placement on the outside of the support railing 112 reduces direct contact between metal components and the salt spray environment. The support column 117 is a load-bearing component vertically fixed to the support platform 111, which can be made of steel pipe or composite material columns, forming the basic support frame for the installation of the navigation light 116. The connector 118 is a transition component connecting the support column 117 and the support railing 112, which can be made of L-shaped metal angle steel or U-shaped clips, forming a closed-loop load-bearing structure through bidirectional connection. The navigation light 116 mounting base is the main mounting platform supporting the navigation light 116, which can be made of a grid-like metal frame or a ring bracket. Its placement between the connectors 118 creates three-dimensional spatial constraints. The top handrail refers to the protective component surrounding the edge of the support platform 111. It can be made of rotomolded polyethylene pipe. The integrated design with the support platform 111 can avoid the corrosion risk of the independent support component 153.

[0086] Specifically, the lightning rod installation position is independently set on the outside of the supporting guardrail 112, physically isolating the lightning rod 115 from the main body of the light post and effectively blocking the continuous exposure of the metal conductive path. The navigation light installation position adopts an array of supporting columns 117, which are bidirectionally connected to the supporting guardrail 112 through connectors 118. When subjected to wind and wave impact, the impact force is transmitted through the supporting columns 117 to the connectors 118, and then distributed by the connectors 118 to the supporting guardrail 112 and the post column 120, forming a three-dimensional load transfer network. The navigation light 116 mounting base is constrained between multiple connectors 118, and its six degrees of freedom are restricted by adjacent components to prevent displacement and loosening. The top handrail is directly fixed to the edge of the supporting platform 111, providing personnel safety protection while utilizing the structural strength of the platform itself to achieve an installation method without additional support.

[0087] Compared to existing technologies, traditional navigation light installations (116) employ a single-column support structure, relying solely on bolt fixation, which carries the risk of stress concentration. Furthermore, the direct connection between the lightning rod (115) and the main structure easily creates corrosion pathways. This solution utilizes a composite connection structure of support column (117) and connector (118) to create a multi-node distributed support system for the navigation light installation location. The independent lightning rod installation location cuts off the path of metal corrosion conduction, and the integrated design of the top handrail and support platform (111) eliminates the rust risks associated with traditional independent guardrails.

[0088] Through the above technical solutions, this application achieves three-dimensional stable fixing of the navigation light 116 mounting base in windy and wave environments, effectively suppressing the relative displacement between the connector 118 and the support column 117, and reducing the risk of fatigue fracture of metal components due to stress concentration. The independent layout of the lightning rod mounting position blocks the diffusion path of salt spray corrosion, extending the service life of the lightning protection system. The integrated structure of the top handrail and support platform 111 ensures maintenance safety while avoiding secondary maintenance work caused by corrosion of traditional independent guardrails.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
