Description

Technical Field

[0001] This application relates to the field of street lighting technology, and more specifically, to a street light and a road lighting system for high-temperature areas. Background Technology

[0002] In related technologies, when connecting streetlights to the roadbed, site clearing and material and equipment preparation are necessary first. Then, on the side of the roadbed, an excavator is used to accurately dig a pit according to the design, controlling the dimensions, verticality, and bottom flatness, and properly stockpiling the excavated soil. Next, formwork is placed, and steel bars conforming to the drawings are processed, tied, and placed into the pit for fixation. Concrete is poured, evenly poured, and vibrated to prevent segregation. Simultaneously, reliable streetlight pole bases and connectors are accurately pre-embedded, using positioning devices to prevent displacement. After the foundation is poured, it is covered with moisture-retaining material and regularly watered for curing, avoiding disturbance during this period. Once the foundation reaches the design strength, the light pole and pole base are cleaned and inspected, securely connected with bolts and nuts, and the verticality of the light pole is adjusted to meet standards.

[0003] When the width of the roadbed is limited on both sides, the space available for construction around the roadbed is extremely limited. In this case, setting up the foundation using traditional methods becomes extremely difficult, or even impossible. Even if foundation construction is forced to proceed, the lack of space may increase the difficulty of construction, make it difficult to guarantee the quality of construction, and may also cause damage to the surrounding environment and existing facilities.

[0004] In order to at least address some of the deficiencies mentioned in the related technologies, this application provides a street light and a road lighting system for high-temperature areas.

[0005] To achieve the above objectives, this application provides a street light for use in high-temperature areas. The street light includes a base assembly and a pole assembly. The base assembly includes at least one fixing member with a connecting surface for mounting the fixing member to a retaining wall in a cut section; the fixing member has a snap-fit ​​portion located away from the connecting surface. The pole assembly includes at least one pole body with a light source at one end; the end of the pole body away from the light source can snap into the snap-fit ​​portion, thereby fixing the pole body relative to the fixing member.

[0006] Furthermore, the snap-fit ​​portion is located at the center of the fixing member, and the fixing member has evenly distributed connecting holes along its edge for inserting expansion bolts, so that the fixing member can be connected to the excavated section retaining wall. Marking points are provided on the excavated section retaining wall to identify the connection positions of the expansion bolts.

[0007] Furthermore, the locking part includes a stiffening plate, which is vertically disposed on the fixing member along the horizontal direction. The stiffening plate has a locking hole that communicates with the outside, and the rod can be locked into the locking hole. At least two stiffening plates are evenly distributed along the vertical direction on the locking part.

[0008] Furthermore, at least two of the aforementioned fasteners are vertically arranged on the retaining wall of the excavated section, and the snap-fit ​​holes in the plurality of fasteners are concentrically arranged. The rod body can pass through the plurality of snap-fit ​​holes in sequence and is fixed relative to the fasteners.

[0009] Furthermore, the diameters of the multiple concentrically arranged snap-fit ​​holes decrease sequentially from top to bottom in the vertical direction; the diameters of the rods are correspondingly arranged so that the rods can snap into the snap-fit ​​holes.

[0010] Furthermore, the lamp post assembly includes a first pole body and a second pole body, the first pole body being snapped onto the snap-fit ​​portion, and the second pole body being connected to the top of the first pole body.

[0011] Furthermore, both the first rod and the second rod are hollow, and the cavities inside the first rod and the second rod are interconnected. The light source is mounted on the end of the second rod away from the first rod.

[0012] Furthermore, the length of the first rod is L1, and the length of the second rod is L2, satisfying: L1≤L2.

[0013] Furthermore, the sum of the distance between the plurality of fasteners and the thickness of the fastener itself is L3, satisfying: L1≥L3.

[0014] This application also provides a road lighting system for high-temperature areas, including a cut section retaining wall and a street light as described in any of the above embodiments, wherein the street light is mounted on the cut section retaining wall via the base assembly.

[0015] With the above technical solution, when installing the streetlight of this application, the fixing component in the base assembly is installed on the retaining wall of the excavated section through the connecting surface. Then, the pole body in the light pole assembly is inserted into the snap-fit ​​part of the fixing component, so that the pole body and the fixing component are relatively fixed. The circuit-related components required by the light source are properly connected so that the light source can emit light normally.

[0016] When installing the streetlights of this application, the base components are directly installed on the retaining wall of the excavated section, eliminating the need to excavate pits and take into account the width of the roadbed on both sides. In actual construction, it will not be restricted by the space on both sides of the roadbed, nor will it cause damage to the surrounding environment and existing facilities. Construction is more flexible, less difficult, and more efficient.

[0026] This embodiment provides a street light to solve the problem in related technologies where the installation of street lights is limited by the space on both sides of the roadbed, resulting in many inconveniences during construction.

[0027] Please see Figure 1 , Figure 2 This embodiment provides a street light for use in high-temperature areas. The street light includes a base assembly 100 and a pole assembly 200. The base assembly 100 includes at least one fixing member 110, which has a connecting surface 111 for mounting the fixing member 110 to the cut section retaining wall 300; the fixing member 110 has a snap-fit ​​portion located away from the connecting surface 111. The pole assembly 200 includes at least one pole body, one end of which has a light source, and the end of the pole body away from the light source can be snapped into the snap-fit ​​portion to fix the pole body relative to the fixing member 110.

[0028] Specifically, when installing the streetlights of this embodiment, the fixing member 110 of the base assembly 100 is installed on the cut section retaining wall 300 via the connecting surface 111. Then, the pole body of the light pole assembly 200 is snapped into the snap-fit ​​part of the fixing member 110, so that the light source on the pole body is in the target position, and the streetlight installation is complete. The circuit-related components required for the light source to emit light are installed normally so that the light source can emit light normally, which will not be described in detail here.

[0029] It should be noted that the cut section retaining wall 300 is a structure used to support and stabilize excavated soil or rock slopes. During the construction of roads, railways, or other infrastructure, it is often necessary to excavate mountains or the ground to create road cuts, i.e., passages below the original ground level. A cut section refers to the road section formed by these excavation operations. To prevent landslides or erosion of the excavated slope, retaining walls are usually installed at the bottom of the slope or along the slope. These retaining walls can withstand pressure from the soil or rock and maintain slope stability. The types of retaining walls used in cut sections include, but are not limited to, gravity retaining walls, cantilever retaining walls, buttress retaining walls, and reinforced retaining walls, depending on the specific circumstances.

[0030] In this embodiment, the base component 100 is installed on the retaining walls 300 of the excavated sections already present on both sides of the road. That is to say, in this embodiment, it is not necessary to excavate pits on both sides of the roadbed to fix the base component 100 during installation. Accordingly, in actual construction, this embodiment is not limited by the space on both sides of the roadbed, nor does it cause damage to the surrounding environment and existing facilities. The construction is more flexible, less difficult, and more efficient.

[0031] It is worth mentioning that the connecting surface 111 is a plane, the purpose of which is to enable the fastener 110 to be stably and reliably attached to the cut section retaining wall 300. After the connecting surface 111 is attached in the appropriate position, the connecting surface 111 and the cut section retaining wall 300 can be relatively fixed by any existing equipment or components, such as expansion bolts, screws, welding, mortise and tenon joints, etc.

[0032] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the snap-fit ​​part is located at the center of the fixing member 110, and the fixing member 110 has evenly distributed connecting holes 113 on its edge for inserting expansion bolts, so that the fixing member 110 can be connected to the cut section retaining wall 300. Marking points are provided on the cut section retaining wall 300 to indicate the connection positions of the expansion bolts. The cut section retaining wall 300 itself has good load-bearing capacity and resistance to lateral earth pressure; using it as the supporting structure for the street light foundation can effectively improve the overall stability of the street light system. Compared with the traditional method of burying concrete foundations on both sides of the roadbed, the installation method in this embodiment can avoid safety hazards caused by foundation settlement or soil loosening.

[0033] The snap-fit ​​part is located at the center of the fixing member 110, which makes the force on the light pole assembly 200 more even, reduces eccentric bending moment, and lowers the risk of structural fatigue damage. Under the influence of external factors such as wind load and temperature changes, the central force helps maintain the verticality and stability of the light pole. The fixing member 110 has evenly distributed connecting holes 113 on its edges, which are used to fix it to the retaining wall with expansion bolts to form a multi-point anchoring structure, which greatly improves the connection strength between the fixing member 110 and the retaining wall. The evenly distributed design also prevents local stress concentration, making the force on the fixing member 110 more even, thereby improving the seismic and wind resistance of the overall structure.

[0034] Pre-marked points on the 300mm retaining wall of the excavated section are used to identify the installation positions of the expansion bolts, ensuring that each fastener 110 is installed according to a uniform standard, improving construction accuracy and consistency. This reduces on-site measurement errors and enhances the stability and safety of the overall structure.

[0035] In one embodiment, exemplarily, such as Figure 1 , Figure 2As shown, the snap-fit ​​part includes a stiffening plate 112, which is vertically mounted on the fixing member 110 along the horizontal direction. The stiffening plate 112 has snap-fit ​​holes that communicate with the outside, allowing the rod to be snapped into the holes. At least two stiffening plates 112 are evenly distributed along the vertical direction on the snap-fit ​​part. The stiffening plates 112, welded or fixed to the fixing member 110 as a reinforcing structure, significantly improve the bending and shear resistance of the snap-fit ​​part. Under stress caused by wind loads, earthquakes, or temperature changes, the stiffening plates 112 effectively prevent deformation or breakage of the snap-fit ​​part.

[0036] Multiple stiffening plates 112 are evenly distributed vertically, allowing the loads on the light pole, such as its own weight and wind loads, to be more evenly distributed to the fixing member 110 and the retaining wall, reducing local stress concentration. Especially in high-temperature areas, materials may generate internal stress due to thermal expansion and contraction; the distribution of stiffening plates 112 helps to alleviate the generated internal stress.

[0037] The snap-fit ​​hole is formed by multiple stiffening plates 112, which, compared to a single-sided or unstiffened structure, better encloses the rod and increases the friction and engagement force at the connection point. This effectively prevents the rod from loosening or falling off during use due to vibration, wind, or other reasons.

[0038] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, at least two fasteners 110 are vertically arranged on the retaining wall 300 of the excavation section, and the snap-fit ​​holes in the multiple fasteners 110 are concentrically arranged. The pole can pass through the multiple snap-fit ​​holes in sequence and be fixed relative to the fasteners 110. The multiple fasteners 110 are distributed vertically, and with the concentrically arranged snap-fit ​​holes, they are equivalent to providing multiple support points in the height direction for the light pole, further improving the installation reliability of this embodiment.

[0039] The weight and external load borne by the light pole can be shared by multiple fasteners 110, avoiding excessive stress on a single connection point. This reduces the risk of fatigue damage to individual connection parts and extends the service life of the street lighting system.

[0040] The concentric arrangement of the snap-fit ​​holes means that all the fasteners 110 have a unified reference axis for installation and positioning, which helps ensure the vertical installation accuracy of the light pole. For batch construction, this facilitates a standardized installation process and reduces on-site adjustment time. Furthermore, in this embodiment, in actual production, the multiple fasteners 110 in the base assembly 100, as well as the pole body, can all be pre-fabricated in the factory and then transported to the construction site for assembly, further reducing on-site construction difficulty and improving installation efficiency.

[0041] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the diameters of multiple concentrically arranged snap-fit ​​holes decrease sequentially from top to bottom in the vertical direction; the diameter of the rod is correspondingly set so that the rod can snap into the snap-fit ​​holes. The snap-fit ​​holes gradually decrease in diameter from top to bottom, and the rod also becomes thinner accordingly, generating a progressive clamping force between the mating surfaces after insertion. In this embodiment, the snap-fit ​​holes and the rod are configured with this wedge-shaped or tapered locking structure, which effectively enhances friction and engagement force, further preventing the rod from loosening or falling off under wind loads, vibrations, or earthquakes.

[0042] The thicker base of the rod creates greater mechanical resistance when inserted into a smaller hole, significantly improving the overall tensile strength of the structure. In high-temperature regions, thermal expansion and contraction of materials can lead to loosening of the connection; however, in this embodiment, this design effectively counteracts the effects of thermal expansion and contraction.

[0043] The larger diameter locking hole at the top acts as a guide, making it easier to insert the rod into the smaller hole below, avoiding installation difficulties due to deviation and improving construction efficiency. As the hole diameter gradually decreases, the rod is continuously constrained by the center during insertion, which also helps maintain its verticality and coaxiality.

[0044] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the light pole assembly 200 includes a first pole body 210 and a second pole body 220. The first pole body 210 is snapped onto a snap-fit ​​part, and the second pole body 220 is connected to the top of the first pole body 210. The first pole body 210 and the second pole body 220 are manufactured and transported separately, resulting in a smaller size and lighter weight, making them more suitable for construction environments in narrow roads or mountainous areas. Installation can be completed on-site simply by connecting the two parts, improving construction efficiency.

[0045] As for the connection method of the first rod 210 and the second rod 220, any existing equipment or components can be selected for connection according to the actual situation. For example, a flange is provided at one end of both the first rod 210 and the second rod 220. During installation, the first rod 210 and the second rod 220 can be directly fixed together by the flange and bolts.

[0046] During high-altitude installation, the shorter first pole 210 is installed first, and then the longer second pole 220 is connected to its top, which reduces the overall hoisting height and difficulty. If a part is damaged, only that part needs to be disassembled and replaced, without having to remove the entire street light. This is very practical for scenarios that require regular maintenance or upgrades to the lighting system.

[0047] Dividing the light pole into two sections allows for a more balanced distribution of weight and stress points. The first pole section 210 provides the primary support, while the second section 220 handles the lighting function. This reduces the risk of overturning due to a high center of gravity at the top and improves the overall structure's wind resistance and stability. Of course, in this embodiment, the length of the second pole section 220 can be flexibly selected based on the actual road width, slope height, or lighting requirements to achieve a customized configuration.

[0048] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, both the first pole 210 and the second pole 220 are hollow, and the cavities inside the first pole 210 and the second pole 220 are interconnected. The light source is installed on the end of the second pole 220 away from the first pole 210. The hollow structure provides a concealed wiring channel for power lines, control lines, etc., making the entire street light look neat and aesthetically pleasing. The wires can be directly passed from the ground junction box into the interior of the first pole 210 and reach the top light source position through the hollow channel without external binding or additional conduit. This avoids exposing external wiring and reduces the risk of failure caused by wind, sun, animal chewing, or human damage.

[0049] In addition, the hollow pole reduces its own weight and top load while ensuring strength, thereby improving the wind resistance stability of the street light system.

[0050] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the length of the first pole 210 is L1, and the length of the second pole 220 is L2, satisfying L1≤L2. The second pole 220 serves as the main lighting support; appropriately lengthening it allows the light source to be at a more ideal lighting height, improving the uniformity and coverage of road lighting. The first pole 210 serves as the basic support, and its length can be adjusted according to the height of the retaining wall for flexible adaptation.

[0051] In actual engineering projects, the height of the retaining wall in the excavation section may vary. By controlling the ratio of L1 ≤ L2, it is possible to adapt to various retaining wall heights without replacing the second pole 220, thus improving the equipment's versatility.

[0052] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the sum of the distance between the multiple fasteners 110 and the thickness of the fastener 110 itself is L3, satisfying: L1≥L3. In other words, after the first rod 210 is installed on the base assembly 100, both ends of the first rod 210 extend vertically beyond the base assembly 100.

[0053] Multiple fasteners 110 are vertically arranged on the retaining wall, with a certain distance between them. If L1 < L3, the length of the first rod 210 is insufficient to cover the height range of all the fasteners 110, which may result in the rod not being able to be fully inserted into the uppermost fastener 110, or only partially passing through some fasteners 110, causing an unstable connection and affecting the overall structural stability. In this embodiment, L1 ≥ L3 ensures that the first rod 210 completely penetrates all the fasteners 110 from bottom to top, and each snap-fit ​​hole can effectively support and constrain the rod, achieving multi-point support and enhancing structural safety.

[0054] In different projects, the height of the retaining wall, the number of fasteners 110, and their spacing may vary. The first pole 210 runs completely through all the fasteners 110 from bottom to top, allowing the same specification of the first pole 210 to be adapted to various fastener 110 layout schemes, improving the product's versatility and reusability. It is particularly suitable for standardized modular production and rapid deployment scenarios.

[0055] This embodiment also provides a road lighting system for high-temperature areas, including a cut section retaining wall 300 and a street light as described in any of the above embodiments. The street light is mounted on the cut section retaining wall 300 via a base assembly 100.

[0056] In this embodiment, the road lighting system for high-temperature areas includes the streetlights in any of the above embodiments, and thus possesses all the beneficial effects of streetlights, which will not be elaborated further here.

[0057] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
