Description

Technical Field

[0001] This invention relates to the field of municipal pole equipment technology, and in particular to a modular and scalable integrated pole supply system and its rapid installation structure. Background Technology

[0002] Currently, most functional poles used in urban infrastructure construction are single-function fixed poles, such as streetlights, surveillance cameras, and traffic signals. The independent placement of these poles not only occupies urban space and creates a cluttered roadscape, but also increases construction, maintenance, and renovation costs. While existing integrated poles have achieved some functional integration, they still have many technical shortcomings.

[0003] Currently, most mainstream smart municipal integrated pole products on the market are manufactured using an integrated welding process. The crossbars and main poles are welded together, with fixed lengths and non-adjustable installation positions. The overall pole structure is simple and cannot be flexibly adapted to different construction scenarios, road widths, installation heights, and functional configuration requirements. This type of integrated pole has shortcomings in practical applications: In terms of functional adaptability, the crossbars of existing integrated poles are mostly fixed-length welded structures with no adjustable extension length. They cannot flexibly adjust the extension distance according to the width of the road, lane distribution, coverage of surveillance lighting, and the number of devices deployed. This often results in crossbars that are too long, encroaching on road boundaries, or too short, causing blind spots in equipment coverage. The equipment installation adaptability and scenario versatility are poor, making it difficult to adapt to complex and ever-changing urban road construction scenarios.

[0004] During the on-site construction and installation phase, traditional composite poles typically use a direct butt-fitting method with ordinary flat flanges to connect the crossbars and main poles, without dedicated positioning pins, guide grooves, or alignment references. During high-altitude installation, the lack of positioning references between the crossbar flange connection holes and the main pole flange holes necessitates repeated fine-tuning and manual visual calibration by construction personnel at height. Alignment accuracy relies entirely on individual experience, making high-altitude operations extremely difficult and time-consuming. Furthermore, prolonged exposure at height significantly increases the safety risks for construction personnel, making it difficult to guarantee both construction safety and installation efficiency.

[0005] While some improved modular integrated pole solutions have gradually emerged in the industry, most existing modular solutions focus on segmented splicing of the main pole, lacking reasonable design for the rapid disassembly, length adjustment, and positioning of the crossbars. Their crossbar extension structures are cumbersome and complex, with redundant disassembly and assembly steps. The positioning accuracy of modular splicing is poor, and the locking reliability is low. They are unable to withstand long-term bending moments caused by wind loads and the weight of the equipment itself. Furthermore, they lack compatibility with the installation interfaces of various municipal equipment such as cameras and lighting fixtures. They cannot meet the core requirements of flexible extension and retraction adjustment of crossbars, rapid functional expansion, and convenient disassembly and assembly of equipment. They have not fundamentally solved the industry pain points of crossbars that cannot be adjusted to be too long, too short, too slow to be installed, or cannot be aligned accurately. They are unable to meet the requirements for the implementation and use of current urban smart transformation and large-scale standardized, modular, and rapid construction of municipal poles.

A pair of limiting blocks are fixedly connected to the surface of the mounting pole, and the limiting blocks are slidably connected to the limiting grooves.

[0008] Preferably, the drive mechanism includes a driven bevel gear fixedly connected to the surface of the threaded rod, the surface of the driven bevel gear meshing with a driving bevel gear, a motor being provided on the outer surface of the fixed base rod, and the output end of the motor passing through the fixed base rod and connected to one side of the driving bevel gear.

[0009] Preferably, a sliding positioning structure is provided between flange one and flange two, and the connection holes are aligned between them through the sliding positioning structure. The sliding positioning structure includes a pair of arc-shaped grooves opened inside flange one, and a pair of cylinders are fixedly connected to the side of flange two near flange one. The cylinders can slide along their arc-shaped trajectory in the arc grooves.

[0010] Preferably, a quick-connect structure is provided between adjacent pole segments. The quick-connect structure includes a circular slot inside the top of the base pole segment, square slots on both sides of the circular slot, and the square slots communicating with the circular slot. A circular block is fixedly connected to the bottom of the functional extension pole segment, and a pair of square blocks are fixedly connected to both sides of the circular block. The square blocks are slidably connected to the square slots, and the circular slots are slidably connected to the circular blocks. A clamp is provided at the connection point of adjacent pole segments.

[0016] Preferably, the top of the top pole segment is provided with a rain cap, which is a conical structure. The lower edge of the rain cap extends 30mm to 50mm beyond the outer wall of the top pole segment to prevent rainwater from flowing into the interior along the outer wall of the top pole segment. The top of the rain cap is provided with a lightning rod mounting base for installing a lightning rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention adopts a segmented modular structure consisting of a basic pole segment, an addable and subtractable functional extension pole segment, and a top pole segment. The number of functional extension pole segments can be flexibly increased or decreased according to the on-site construction height and functional requirements, adapting to the pole height requirements of different scenarios. It breaks away from the limitations of traditional integrated poles with fixed specifications and no adjustability, reduces production and customization costs, and is suitable for various usage scenarios such as urban roads, parks, and residential areas.

[0018] 2. This invention features a dedicated quick-connect structure. Through the sliding fit of circular and square slots with corresponding circular and square blocks, combined with clamp reinforcement, it enables quick engagement, positioning, and fixation of the pole segments, ensuring the coaxiality and structural stability of the pole segment connection and preventing loosening over long-term use. In conjunction with the arc-shaped groove and cylindrical sliding positioning structure between flanges, it can quickly complete the alignment of connection holes without the need for repeated manual calibration, thus improving assembly and construction efficiency.

[0019] 3. The crossbar module of the present invention adopts a telescopic structure. The extension length of the installation rod can be adjusted by driving the threaded rod to rotate through the drive mechanism. The coverage range of the crossbar can be flexibly adjusted according to different road widths and equipment layout requirements. There is no need to pre-customize crossbars of different lengths, which further improves adaptability.

[0020] 4. The mounting rod in this invention has vertical and horizontal grooves inside. Through the threaded engagement between the rod and the mounting base, devices such as cameras and lights can be securely locked in a preset position, preventing angular displacement caused by wind vibration or their own weight, and ensuring the long-term stability of the device's working posture. At the same time, the vertical and horizontal groove design provides multi-dimensional adjustment space for device installation, and the through holes at the bottom of the grooves can promptly drain any small amount of water that may accidentally enter.

Detailed Implementation

[0023] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0024] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0025] Example: Please see Figures 1-9 This embodiment proposes a modular and scalable integrated pole supply system and its rapid installation structure. The device mainly consists of four parts: a base 1, a base pole segment 2, at least one functional extension pole segment 3, and a top pole segment 4.

[0026] The foundation base 1 is a steel flange structure pre-embedded in the ground, with its top welded to the bottom of the foundation pole segment 2. The foundation pole segment 2, serving as the load-bearing base of the entire pole, is made of large-diameter, thick-walled steel pipe to ensure the overall structural bending strength and stability. The top of the foundation pole segment 2 is detachably connected to the bottom of the functional extension pole segment 3 via a quick-connect structure, and the top of the functional extension pole segment 3 is also connected to the bottom of the top pole segment 4 via a quick-connect structure. This modular, segmented design allows the total height of the pole to be flexibly combined and expanded according to the actual needs of different application scenarios (such as traffic monitoring, smart lighting, and 5G communication coverage), eliminating the need to redesign and manufacture an integral pole, reducing production and storage costs, and improving on-site deployment efficiency.

[0027] Several flanges 5 are fixedly connected circumferentially to the outer periphery of the top segment 4. The number and arrangement angle of the flanges 5 are pre-set according to the mounting requirements of the crossbar module 7, for example, two are arranged symmetrically or four are arranged at a 90° angle. A flange 6 is detachably connected to one side of each flange 5, and the crossbar module 7 is fixedly connected to the side of the flange 6 away from the flange 5. The crossbar module 7 is the core unit for mounting functional equipment in this embodiment. It consists of two sections: a fixed base rod 8 and a mounting rod 9. One end of the fixed base rod 8 is welded to the flange 6, and its interior is hollow and accommodates the drive mechanism 16 and the threaded rod 14. The mounting rod 9 serves as an extension arm for mounting terminal equipment such as cameras and lighting lamps.

[0028] In order to achieve the guiding and anti-rotation functions of the mounting rod 9 inside the fixed base rod 8, the present invention designs a guiding and limiting structure between the fixed base rod 8 and the mounting rod 9.

[0029] like Figure 4 and Figure 9 As shown, a circular groove 23 is formed inside the fixed base rod 8, extending through its inner cavity along the axial direction of the fixed base rod 8. The inner diameter of the groove 23 matches the outer diameter of the mounting rod 9, allowing the mounting rod 9 to slide smoothly within the groove 23. A pair of limiting grooves 22 are formed on opposite sides of the inner wall of the circular groove 23 in the diametrical direction. The limiting grooves 22 extend along the axial direction of the fixed base rod 8 and communicate with the circular groove 23. A pair of limiting blocks 24 are fixedly connected to the outer surface of the mounting rod 9 at corresponding positions. The limiting blocks 24 extend along the axial direction of the mounting rod 9, and their cross-sectional dimensions match the cross-sectional dimensions of the limiting grooves 22. The limiting blocks 24 are slidably connected to the limiting grooves 22. When the drive mechanism 16 drives the threaded rod 14 to rotate, the limiting blocks 24 slide within the limiting grooves 22. Due to the rectangular cross-section fit between the limiting blocks 24 and the limiting grooves 22, the mounting rod 9 cannot rotate circumferentially relative to the fixed base rod 8 and can only move linearly along the axial direction. This guide and limiting structure ensures that the helical drive between the threaded rod 14 and the internal thread groove 15 can be reliably converted into the extension and retraction of the mounting rod 9, avoiding the extension and retraction failure caused by the mounting rod 9 rotating together with the threaded rod 14.

[0030] The mounting rod 9 has several mounting seats 10 inside, which are spaced apart along the axial direction of the mounting rod 9. These mounting seats 10 are used to install smart city terminal equipment such as cameras, lights, and environmental sensors. The mounting seats 10 adopt an embedded layout inside the mounting rod 9, which can effectively prevent the equipment from being damaged by wind and rain and accidental impacts compared with traditional external brackets, thus improving the long-term reliability and service life of the equipment.

[0031] To achieve rapid, electric adjustment of the crossbar length, a threaded rod 14 is axially arranged inside the fixed base rod 8, while an internal threaded groove 15 coaxial with it is opened inside the mounting rod 9. The threaded rod 14 and the mounting rod 9 form a transmission engagement through a thread 29. A drive mechanism 16 is also provided inside the fixed base rod 8, which is connected to the threaded rod 14 and used to drive the threaded rod 14 to rotate. Specifically, the drive mechanism 16 includes a driven bevel gear 161 fixedly connected to one end of the threaded rod 14, and a driving bevel gear 162 meshes with the surface of the driven bevel gear 161. A servo motor 163 is fixedly mounted on the outer surface of the fixed base rod 8. The output end of the servo motor 163 passes through the side wall of the fixed base rod 8 and is connected to the central shaft of the driving bevel gear 162. When the servo motor 163 is powered on, its output end drives the driving bevel gear 162 to rotate. The driving bevel gear 162 transmits power to the driven bevel gear 161 through a bevel gear pair, thereby driving the threaded rod 14 to rotate smoothly under the support of bearings inside the fixed base rod 8. The meshing action between the threaded rod 14 and the internal thread groove 15 of the mounting rod 9 converts the rotational motion into linear motion of the mounting rod 9 along the axial direction, thereby achieving stepless adjustment of the crossbar length. This electric adjustment function is suitable for scenarios that require periodic adjustment of equipment coverage or equipment maintenance. It can be operated from the ground via a controller without the need for working at height, improving maintenance convenience and operational safety.

[0032] Furthermore, in order to achieve rapid and precise docking between flange 5 and flange 6, the present invention integrates a sliding positioning structure 11 into the flange connection structure.

[0033] like Figures 3-4As shown, a sliding positioning structure 11 is provided between flange 5 and flange 6, which aligns the connecting holes between them. This sliding positioning structure 11 includes a pair of arc-shaped grooves 12 formed inside flange 5. These grooves 12 are centrally symmetrically distributed on the end face of flange 5, with the center of their arc trajectory coinciding with the axis of flange 5. A pair of cylinders 13 are fixedly connected to the end face of flange 6 near flange 5, and the positions of these cylinders 13 correspond one-to-one with the positions of the arc-shaped grooves 12. When assembling the crossbar module 7, the operator only needs to align the two cylinders 13 on flange 6 with the opening ends of the two arc-shaped grooves 12 on flange 5, and then rotate flange 6 clockwise by a certain angle. The cylinders 13 then slide along their arc trajectory within the arc-shaped grooves 12 until they reach the end limit of the arc-shaped grooves 12. At this point, all connecting holes on flange 5 and flange 6 are automatically circumferentially aligned, without the need for repeated manual adjustments or auxiliary tooling. Subsequently, the operator can easily insert the bolts and tighten the nuts to complete the flange connection. This sliding positioning structure 11 transforms the traditional blind hole-fitting operation into a two-step operation of insertion followed by rotation, reducing the difficulty of working at heights and the hole-fitting time, and is especially suitable for installation environments at night or in low light.

[0034] In addition, in order to achieve rapid assembly and reliable locking between adjacent pole segments, the present invention provides a quick connection structure at the pole segment connection.

[0035] like Figure 2 and Figure 7As shown, the quick-connect structure includes a circular slot 17 formed inside the top of the base segment 2. This circular slot 17 is a cylindrical cavity recessed downwards from the top end face of the base segment 2, its inner diameter matching the outer diameter of the functional extension segment 3. Vertically extending square grooves 18 are formed on opposite sides of the inner wall of the circular slot 17 in the diametrical direction. The square grooves 18 communicate with the circular slot 17 and extend from the top end face of the base segment 2 to the bottom of the circular slot 17. Correspondingly, a circular block 19 is fixedly connected to the bottom of the functional extension segment 3, the outer diameter of which forms a clearance fit with the inner diameter of the circular slot 17. A pair of square blocks 20 are fixedly connected to the outer peripheral wall of the circular block 19 at corresponding positions, the outline dimensions of which match the cross-sectional dimensions of the square grooves 18. When assembling the functional extension pole segment 3, the operator vertically lifts the segment, aligning the bottom circular block 19 and square block 20 with the circular slot 17 and square slot 18 at the top of the base pole segment 2, respectively. Then, the functional extension pole segment 3 is lowered vertically. During the lowering process, the square block 20 slides down along the square slot 18 until the bottom surface of the circular block 19 contacts the bottom surface of the circular slot 17. At this point, the functional extension pole segment 3 has reached the predetermined installation position. A clamp 21 is fitted onto the outside of the connection between adjacent pole segments and tightened. The inner wall of the clamp 21 is tightly fitted against the outer walls of the base pole segment 2 and the functional extension pole segment 3, further securing the connection through radial clamping force. This also serves to seal and waterproof the connection while enhancing its rigidity. This quick-connect structure eliminates the traditional flange bolt connection method, simplifying the cumbersome connection process that originally required dozens of bolts into three steps: insertion, rotation, and clamp tightening. In large-scale municipal engineering installation scenarios, this can shorten the construction cycle and reduce labor costs.

[0036] Regarding the installation and fixing of the mounting base 10 inside the mounting rod 9, the present invention adopts a unique cross-positioning structure design.

[0037] like Figure 5As shown, a vertical groove 25 and a horizontal groove 26 are formed inside one end of the mounting rod 9. The vertical groove 25 extends axially along the mounting rod 9, with its opening facing upwards, for accommodating and mounting equipment. The horizontal groove 26 extends radially along the mounting rod 9, intersecting the vertical groove 25 at right angles in space. The mounting base 10 is disposed inside the vertical groove 25, with its bottom surface abutting against the bottom surface of the vertical groove 25. A insertion rod 27 is provided inside the horizontal groove 26. The insertion rod 27 is inserted into the mounting rod 9 along the guiding direction of the horizontal groove 26, with its front end passing through the horizontal groove 26 and extending into the area of ​​the vertical groove 25, and inserting into the positioning hole opened on the side wall of the mounting base 10, thereby locking the axial position of the mounting base 10 within the vertical groove 25. The portion of the insertion rod 27 near its front end is provided with an external thread 29, and the mounting base 10 has a threaded hole 30 inside that matches the external thread 29. The front end of the insertion rod 27 passes through the horizontal groove 26 and is threadedly connected to the threaded hole 30 of the mounting base 10. The portion of the insert 27 away from the external thread 29 is a smooth surface. This smooth surface slides into the inner wall of the transverse groove 26, allowing the insert 27 to slide freely along the transverse groove 26 before being screwed into the mounting base 10, facilitating adjustment of the insertion position. Once the mounting base 10 is adjusted to the predetermined position within the vertical groove 25, the insert 27 is pushed into the transverse groove 26 until its front external thread 29 contacts the threaded hole 30 of the mounting base 10. Then, the rear end of the insert 27 is rotated (e.g., using an Allen wrench), and the external thread 29 is screwed into the threaded hole 30, tightening and fixing the mounting base 10 within the vertical groove 25. One side of the insert 27 is tightly pressed against the outer wall of the groove opening. Simultaneously, the smooth surface portion of the insert 27 remains within the transverse groove 26, serving as a guide and support. This cross-positioning structure allows the mounting base 10 to be flexibly adjusted in the vertical groove 25 according to the size and center of gravity of the equipment, without the need to open additional fastener through holes on the outer wall of the mounting rod 9, ensuring the integrity and aesthetics of the outer wall of the mounting rod 9, while also avoiding the risk of rainwater seeping into the interior through the fastener gaps.

[0038] To ensure good drainage inside the mounting rod 9 and prevent corrosion of equipment or circuits due to rainwater or condensation accumulation, this invention provides several through holes 31 at the bottom of both the horizontal groove 26 and the vertical groove 25. These through holes 31 are connected to the horizontal groove 26 and the vertical groove 25 respectively, and extend to the outer surface of the mounting rod 9. When rainwater accidentally enters the vertical groove 25 or the horizontal groove 26, it can quickly flow into the through holes 31 under the action of gravity and smoothly drain out of the mounting rod 9, thereby keeping the internal environment dry and extending the service life of the internal electrical equipment and connecting cables.

[0039] To facilitate on-site construction and subsequent maintenance, at least one inspection window 32 is provided on the side wall of both the functional extension pole segment 3 and the top pole segment 4. This inspection window 32 is located at a predetermined height on the side wall of the pole segment, with an opening size sufficient to accommodate an operator's arm or specialized tools. An inspection cover 33 is detachably installed at the inspection window 32. The inspection cover 33 is fixedly connected to the side wall of the pole segment by screws or clips, and a sealing gasket is provided at the connection point to prevent rainwater ingress. When routine inspections, troubleshooting, or software upgrades are required for the wiring terminals, communication modules, or power modules, maintenance personnel only need to unscrew the screws or open the clips to remove the inspection cover 33 and operate the internal equipment through the inspection window 32, without disassembling the entire pole segment, significantly reducing maintenance difficulty and time costs.

[0040] In this embodiment, the basic pole segment 2, the functional extension pole segment 3, and the top pole segment 4 are all vertically arranged hollow cylindrical 13-shaped steel pipe structures with the same outer diameter. This hollow structure has a dual function: on the one hand, the hollow cavity can be used for cables and optical cables to pass through, realizing the integrated design of the pole structure and cable channel, avoiding the mess and safety hazards caused by traditional external wiring on poles; on the other hand, the hollow section has a higher bending section modulus with the same amount of material, which can provide better structural strength and stiffness compared to solid poles, while reducing the overall weight and facilitating transportation and hoisting.

[0041] To prevent rainwater from flowing into the pole body along the outer wall of the pole section, a rain cap 34 is provided at the top of the top pole section 4. This rain cap 34 has a conical structure, with its lower edge extending 30mm to 50mm beyond the outer wall of the top pole section 4, forming a ring of eaves. This effectively guides rainwater, causing it to drip along the conical surface of the rain cap 34 to the ground, preventing it from flowing down the outer wall of the top pole section 4 and seeping into the connection gaps between adjacent pole sections or the maintenance window 32. A mounting base 10 is also provided at the top of the rain cap 34 for installing a lightning rod 28, giving the pole lightning protection functionality and protecting the equipment on the pole and surrounding facilities from lightning strikes.

[0042] In summary, this invention deeply integrates modular pole assembly, electric crossbar extension and retraction, quick flange positioning, rapid pole segment connection, internal equipment installation and drainage, and rain and lightning protection into a single unit. Once assembled, the device forms a complete and flexibly expandable integrated pole supply system, eliminating the need for additional external brackets and wiring conduits. This simplifies the construction process for urban infrastructure, improves structural compactness and aesthetic harmony, and provides reliable structural support for the large-scale deployment and efficient operation and maintenance of multifunctional poles in smart cities.

[0043] Based on the above embodiments, the modular expansion structure of the present invention can be flexibly adapted to different construction scenarios. In low-height scenarios such as low-rise roads and small parks, the functional expansion pole segment 3 can be eliminated, and the top pole segment 4 can be directly spliced ​​with the basic pole segment 2 to reduce the overall height of the pole. In high-height and multi-functional scenarios such as urban main roads and large venues, multiple sets of functional expansion pole segments 3 can be added to increase the height of the pole. At the same time, multiple sets of flanges and crossbar modules 7 can be added according to functional requirements to carry more monitoring and lighting equipment, making it highly expandable.

[0044] In this embodiment, the integrity of the device is first confirmed. During installation, the base base 1 is first fixed in the preset construction position, and the base segment 2 is welded and fixed to the base base 1 to complete the bottom foundation construction. According to the actual required height of the poles, the corresponding number of functional extension pole segments 3 are selected. The round blocks 19 and square blocks 20 at the bottom of the functional extension pole segments 3 are aligned with the round slots 17 and square slots 18 at the top of the base segment 2 and slid in to complete the quick positioning and splicing. After the splicing is completed, the clamps 21 are installed at the connection to lock and fix it. In the same way, the top pole segment 4 is assembled on the top of the uppermost functional extension pole segment 3 to complete the segmented assembly of the entire pole.

[0045] When installing the crossbar module 7, align the cylinder 13 of flange 2 6 with the arc groove 12 of flange 1 and insert it. Slide flange 2 6 along the arc groove 12 to quickly align the two sets of flange connection holes. Secure flange 1 and flange 2 6 with bolts to achieve rapid assembly of the crossbar module 7.

[0046] During equipment use, if it is necessary to adjust the extension length and coverage of the camera and lighting, the motor 163 on the outside of the fixed base rod 8 is started. The motor 163 drives the active bevel gear 162 to rotate, and through the bevel gear meshing transmission, it drives the driven bevel gear 161 and the threaded rod 14 to rotate synchronously. The threaded rod 14 cooperates with the threaded groove 15 inside the mounting rod 9, driving the mounting rod 9 to smoothly extend and retract along the circular groove 23 of the fixed base rod 8. The limiting block 24 slides within the limiting groove 22 to prevent it from falling off, thereby realizing the flexible adjustment of the position of the functional equipment.

[0047] When disassembling and maintaining cameras and lighting fixtures, simply rotate the insert rod 27 inside the horizontal slot 26 to release the locking relationship between the insert rod 27 and the external thread 29 of the mounting base 10, and the mounting base 10 along with the equipment can be removed from the vertical slot 25. For installation, the reverse operation allows for quick locking and fixation, making the process convenient. During daily use, rainwater entering the vertical slot 25 and horizontal slot 26 will be quickly discharged through the bottom through hole 31, preventing water accumulation and corrosion of the equipment and rod structure.

[0048] All cables inside the pole are concealed for enhanced protection. The conical rain cap 34 at the top prevents rainwater from seeping into the pole. The lightning rod 28 mounting base 10 can be fitted with a lightning rod 28 for lightning protection.
