[0002] With the rapid advancement of the construction of smart cities, the urban road lighting system no longer only performs the lighting function but gradually develops into a smart street lamp system integrating multiple functions such as lighting, monitoring, communication, and environmental monitoring. Such a system requires installing various controllers, communication modules, and other equipment inside the lamp post, which puts strict requirements on the installation method of the equipment. In practical applications, more than 80% of the equipment in the smart street lamp renovation project is installed inside the lamp post. Such equipment usually includes core components such as intelligent controllers, communication gateways, and power modules.
[0003] Currently, there are mainly three ways to install equipment inside the lamp post: one is to directly fix it on the inner wall of the lamp post with bolts, the second is to use the rail fixing method, and the third is to use the bracket suspension method. Among them, although the direct fixing method has a simple structure, it takes a long time to install, and once the equipment is fixed, it is difficult to adjust the position and angle; although the rail fixing method is flexible in installation, it requires embedding rails inside the lamp post, increasing the upfront construction cost; the bracket suspension method has problems such as poor stability and limited bearing capacity.

Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0036] like Figure 1-3The diagram shows a structural schematic of a device for installing equipment inside a light pole, provided by this utility model. It includes a fixing plate 10 and two support plates 20. The fixing plate 10 is rectangular, with a length ranging from 200-600mm, preferably 300-400mm, and a width ranging from 100-300mm, preferably 150-200mm. The fixing plate 10 is made of a metal material with a thickness of 2-5mm, preferably 304 stainless steel or Q235 carbon steel, with 304 stainless steel being the most preferred. First connecting portions 11 are provided on both sides of the fixing plate 10. The first connecting portions 11 can adopt a folded edge structure or a welded structure, preferably a welded structure to improve connection strength. The fixing plate 10 is provided with several fixing members 12, which are equally spaced mounting holes with a diameter ranging from 6-12mm, preferably 8-10mm. The two support plates 20 are arranged parallel to each other and perpendicularly connected to the fixing plate 10. The support plate 20 is rectangular, with a length ranging from 150-400mm, preferably 200-300mm, and a width ranging from 50-150mm, preferably 80-100mm. The support plate 20 is made of the same material as the fixing plate 10, with a thickness ranging from 2-5mm. A second connecting portion 21 is provided on one side of the support plate 20. The two corners of the support plate 20 away from the second connecting portion 21 are arc-shaped, with a radius of 8-15mm, preferably 10-12mm. An L-shaped opening 22 is provided inside the support plate 20, comprising a first side 221 and a second side 222. The included angle β between the first side 221 and the second side 222 is 70°-120°, preferably 85°-95°; the included angle α between the first side 221 and the second connecting portion 21 is 15°-45°, preferably 25°-35°. The width of the L-shaped opening 22 is 0.5-2 mm larger than the bolt diameter, preferably 1-1.5 mm larger. An anti-slip strip, made of wear-resistant polyurethane material, is provided on the inner wall of the L-shaped opening 22. Simultaneously, a wear-resistant layer is also provided on the inner wall of the L-shaped opening 22, with a surface roughness Ra value of 1.6-3.2 μm, preferably 2.0-2.5 μm. This device is mainly used for mounting the panel 30 of the equipment. The panel 30 is cuboid or cube-shaped, and bolts 31 for mounting are provided on it. The bolts 31 are located at the center of the circumcircle of the panel 30 and on two outer walls of the panel 30.
[0037] like Figure 4-6 As shown, the method of using this device is as follows:
[0038] 1. First, fix the fixing plate 10 to the inner wall of the lamp post using the fastener 12;
[0039] 2. Then, align the bolts 31 of the device panel 30 with the L-shaped opening 22;
[0040] 3. Slide bolt 31 along the first side 221 of the L-shaped opening 22;
[0041] 4. When the bolt 31 reaches the corner of the L-shaped opening 22, rotate the equipment panel 30;
[0042] 5. Slide the bolt 31 along the second side 222 until it is in place. At this time, the equipment panel 30 is in a downwardly inclined state;
[0043] 6. Finally, tighten the bolt 31 to complete the installation.
[0044] Specifically, the principle of the present utility model is as follows: Analyzed from the perspective of mechanical principles, the L-shaped guide groove structure of the present utility model has unique kinematic characteristics. The included angle between the first side and the second side of the guide groove is designed within the range of 70° to 120°. The setting of this angle range is based on three considerations: First, this angle range ensures a smooth and continuous movement trajectory of the equipment during rotation, avoiding rotation dead angles; Second, this angle range can provide sufficient torque support to keep the equipment stable at any position; Third, this angle range matches the position of the equipment's center of gravity to ensure that the equipment can obtain the maximum gravity fixing effect when in the downward position.
[0045] The included angle between the first side of the guide groove and the second connecting portion is designed within the range of 15° to 45°. This design directly affects the final installation angle of the equipment. Through theoretical calculation and experimental verification, when the equipment panel forms an included angle of 15° to 45° with the horizontal plane, it can prevent rainwater from entering the equipment to the greatest extent. This is because within this angle range, rainwater will naturally flow down along the surface of the equipment without forming water accumulation on the surface of the equipment. At the same time, this angle range also ensures that the heat dissipation performance of the equipment is not affected.
[0046] The present utility model also innovatively proposes a mathematical relationship between the side length of the guide groove and the size of the equipment: . The establishment of this relational expression is based on kinematic analysis to ensure the integrity of the equipment's movement trajectory during rotation. Among them, the coefficient 1.5 is the optimal value obtained through a large number of experiments. It not only ensures sufficient movement space but also avoids excessive structural dimensions. The item reflects the influence of the equipment size on the guide groove design, ensuring the general adaptability of the device.
[0047] From the perspective of structural design, the present utility model adopts as Figure 2 shown, the interface forms an overall "匚"-shaped layout, and this layout has good mechanical properties. The two parallel support plates provide stable lateral support, and the vertically arranged fixed plate bears the main bearing role. The arc-shaped corners on the support plates not only avoid stress concentration but also improve the safety of the structure. This structural design not only ensures sufficient strength but also realizes the optimal utilization of materials.
[0048] The 5° slight tilt angle between the guide channel and the horizontal plane, seemingly simple, actually embodies profound physical principles. The lateral force generated by this angle, under the influence of gravity, forms a preload, effectively preventing equipment swaying. At the same time, this angle does not affect the normal installation and operation of the equipment. Finite element analysis has verified that this angle maintains good stability under various working conditions.
[0049] Furthermore, this invention employs a wear-resistant layer with a specific roughness on the inner wall of the guide groove, a design based on tribological principles. The surface roughness range of 1.6-3.2 μm ensures smooth rotational operation of the equipment while providing sufficient friction. This surface treatment not only extends the service life of the guide groove but also improves the overall reliability of the device.
[0050] In summary, this utility model proposes a device solution that is easy to install and maintain by comprehensively considering the principles of gravity, kinematic characteristics, and mechanical properties. The various technical features of this solution complement each other and are organically unified, together forming a complete technical solution.
[0051] A specific embodiment of this utility model is provided below; see [link / reference] Figures 1-3 This utility model provides a device for installing equipment inside a light pole, including a fixing plate 10 and two support plates 20. This device is suitable for light poles with a diameter of 100-300mm, and is particularly suitable for installing equipment such as intelligent lighting controllers and communication gateways.
[0052] The fixing plate 10 is rectangular, with a length ranging from 200-600mm, preferably 300-400mm, and a width ranging from 100-300mm, preferably 150-200mm. The fixing plate 10 is preferably made of 304 stainless steel sheet with a thickness of 3mm, which has good corrosion resistance and mechanical strength. First connecting parts 11 are provided on both sides of the fixing plate 10. The first connecting parts 11 are angle steel structures and are connected to the fixing plate 10 by welding. Argon arc welding is used, with a weld height of 2-3mm. This connection method ensures structural strength. Four fasteners 12 are evenly spaced along the length of the fixing plate 10. The fasteners 12 are M8 mounting holes with a hole spacing of 100mm. This layout ensures that the fixing plate 10 is evenly stressed.
[0053] Two support plates 20 are arranged in parallel and perpendicularly connected to the fixing plate 10. The distance between the two support plates 20 is 100-200mm, preferably 150mm. Each support plate 20 is rectangular, with a length of 250mm and a width of 100mm. The support plates 20 are made of 304 stainless steel sheet of the same specifications as the fixing plate 10. One side of each support plate 20 forms a second connecting part 21 via an angle steel structure. The second connecting part 21 is connected to the first connecting part 11 using the same welding process. The height of the second connecting part 21 is 30-50mm, preferably 40mm. The two corners of the support plate 20 furthest from the second connecting part 21 are arc-shaped, with an R10 rounded transition. This design helps avoid stress concentration.
[0054] The support plate 20 has an L-shaped opening 22. The L-shaped opening 22 is characterized in that its inner corner is positioned relative to the second connecting part 21. Specifically, the inner corner is 80mm from the upper edge of the support plate 20 and 60mm from the connecting edge between the support plate 20 and the second connecting part 21. The L-shaped opening 22 includes a first side 221 and a second side 222. The first side is 80mm long, the second side is 50mm long, and both sides are 10mm wide. The angle between the first side and the second side is 90°, and the angle between the first side and the second connecting part 21 is 30°.
[0055] The L-shaped opening 22 intersects the left side of the support plate 20, dividing the side into upper and lower segments. The first segment, closer to the second connecting part 21, is 100mm long, and the second segment, farther from the second connecting part 21, is 70mm long. The length of the first segment is greater than the radius of the outer circle of the device panel 30 (the radius of the outer circle of the device panel 30 is 80mm), and this dimensional design ensures the stability of the equipment during installation. The distance between the point of the L-shaped opening 22 closest to the second connecting part 21 and the second connecting part 21 is 90mm, which is also greater than the radius of the outer circle of the device panel 30.
[0056] The inner wall of the L-shaped opening 22 is provided with anti-slip strips 23, which are made of polyurethane material with a hardness of 95A and a thickness of 1mm. The inner wall of the L-shaped opening 22 is also plasma-sprayed to form a wear-resistant layer 24, with a surface roughness Ra value of 2.0μm. The width of the opening is 1mm larger than the diameter of the equipment mounting bolt 31. This gap design ensures smooth movement of the bolt while preventing wobbling.
[0057] The device panel 30 installed with this device is a cuboid controller measuring 200mm × 150mm × 60mm. An M8 mounting bolt 31 is located on each side of the device panel 30, specifically at the center of the outer circle of the device panel 30, 80mm from the top edge and 100mm from the left and right edges.
[0058] During installation, first, fix the mounting plate 10 to the inner wall of the light pole with four M8 bolts, with a fixing torque of 20 N·m. Then, align the two mounting bolts 31 on the left and right sides of the equipment panel 30 with the L-shaped openings 22 on the two bracket plates 20. Insert the bolts 31 into the upper end of the L-shaped opening 22 and slide them downwards along the first side for approximately 60 mm. When the bolts 31 reach the corner of the L-shaped opening 22, rotate the entire equipment panel 30 forward by approximately 60°. At this point, the bolts 31 will slide into place along the second side, ultimately causing the equipment panel 30 to tilt downwards at a 15° angle. Finally, tighten the bolts 31 to 18 N·m to complete the installation.
[0059] The present invention also provides a second embodiment, which differs from the first embodiment in that the fixing plate and the support plate are both made of galvanized sheet, a first magnet 32 is provided at the midpoint of the two side walls of the panel, and a second magnet 33 is provided at the midpoint of the second connecting part of the support plate. The first magnet 32 and the second magnet 33 are arranged with opposite poles attracting each other, so as to fix the panel by the magnetic force between the magnets during the rotation of the panel. Furthermore, the first magnet and the second magnet are both made of strong magnet blocks.
[0060] It should be noted that the panel mentioned in this utility model can also be a device box.
[0061] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
