Description

Technical Field

[0001] This invention relates to the field of aluminum profile technology, and in particular to a corrosion-resistant aluminum profile for embedded street light poles. Background Technology

[0002] Streetlights are municipal structures installed along roadsides to provide illumination for people or vehicles. The lights are mounted on streetlight poles, most of which are pre-embedded structures, and some are made of aluminum profiles. Most aluminum profile streetlight tubes are hollow, with wiring running through the hollow portion. It is well known that aluminum alloys can have their corrosion resistance increased through heat treatment; however, the heat treatment effect on the hollow portion of the streetlight pole is not as good as on the outer surface. Therefore, the inner wall of the aluminum alloy streetlight pole has lower corrosion resistance than the outer surface. Furthermore, since the bottom of the streetlight pole is exposed to the ground, moisture can easily accumulate in the hollow portion, increasing the risk of corrosion in the center of the pole. Additionally, the existing hollow structure of the streetlight pole makes it susceptible to deformation under significant external forces. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention proposes a corrosion-resistant aluminum profile for pre-embedded street light poles.

[0004] The present invention proposes a corrosion-resistant aluminum profile for pre-embedded street light poles, comprising a tubular profile made of aluminum alloy, the tubular profile comprising an outer tube and an inner tube sleeved inside the outer tube, the inner tube being detachably installed inside the outer tube, a wiring loop cavity being formed between the outer tube and the inner tube, and a pre-embedded plate being installed at the bottom of the outer tube;

[0005] The cable routing ring cavity is provided with a support positioning ring that abuts against the outer tube and the inner tube. The support positioning ring has a through hole for the cable routing tube to pass through. The cable routing tube is arranged in the cable routing ring cavity and passes through the support positioning ring. There are at least two sets of support positioning rings, and at least two sets of positioning rings are distributed along the axial direction of the inner tube. A closed cavity is formed between any two adjacent sets of support positioning rings.

[0006] The corrosion resistance of the wiring ring cavity is increased by setting at least two sets of support positioning rings. Furthermore, the strength of the street light pole is increased to a certain extent by the structure of the outer tube and inner tube, making it less prone to deformation when subjected to external forces.

[0007] Preferably, the outer wall of the outer tube has a limiting through hole, and a limiting support member for supporting and positioning the supporting positioning ring is detachably installed in the limiting through hole. The limiting support member has a portion extending between the outer tube and the inner tube to support the supporting positioning ring. Preferably, the limiting support member is snapped into the limiting through hole. If the street light pole is hit by an external force and the force is large, the limiting support member will disengage from the limiting through hole, thereby allowing the supporting positioning ring to move relative to the outside tube, which reduces the force on the inner tube and the outer tube to a certain extent and plays a role in shock absorption.

[0008] Preferably, the outer wall of the inner tube has a support groove, and the portion of the limiting support extending into the wiring ring cavity extends into the support groove.

[0009] Preferably, the portion of the limiting support member located in the wiring ring cavity is arranged to gradually slope downwards from the end closer to the inner tube to the end farther away from the inner tube.

[0010] Preferably, the limiting through hole is opened in the horizontal direction, and the limiting support has a portion that contacts the limiting through hole.

[0011] Preferably, the bottom of the outer pipe is fitted with an embedded plate via a column, and there is an internal pouring distance between the embedded plate and the inner pipe. A pouring pipe extends from the inner pipe, which can be used to connect with the pouring system. A sealing plate is provided at the lower end of the inner pipe, and the pouring pipe is placed on the sealing plate and communicates with the inner pipe. During the pouring process, the outer pipe, inner pipe, and embedded plate are first placed in the embedded pit. Then, the discharge port of the external cement equipment is connected to and sealed with the inner pipe, thereby creating a downward force in the inner pipe. This ensures the positioning of the street light tube during the pouring process. Cement is then discharged through the pouring pipe onto the embedded plate. Since there is a pouring distance between the inner pipe and the embedded plate, cement is also poured between the inner pipe and the embedded plate, increasing the support of the inner pipe. At the same time, since the wiring ring cavity is located above and opposite the embedded plate, some cement is also filled at the bottom of the wiring ring cavity, increasing the corrosion resistance of the street light tube.

[0012] Preferably, a sleeve is installed on the pre-embedded plate, the sleeve is fitted over the outer pipe and an outer casting cavity is formed between the sleeve and the outer pipe, and the outlet of the casting pipe is opposite to the casting cavity.

[0013] Preferably, the outlet of the casting pipe is located between the outer pipe and the pre-embedded plate.

[0014] Preferably, the sleeve is vertically rotatably mounted on the pre-embedded plate.

[0015] Preferably, the inner wall of the sleeve is provided with fan blades extending into the casting cavity, and the cement discharged from the casting pipe impacts the fan blades.

[0016] The corrosion-resistant aluminum profile for pre-embedded street light poles proposed in this invention has a simple structure. The structure of the pre-embedded plate, outer tube, inner tube and support positioning ring increases the corrosion resistance of the street light pole to a certain extent; and further improves the strength of the street light pole to prevent deformation.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figure 1-3 As shown, the present invention proposes a corrosion-resistant aluminum profile for pre-embedded street light poles, comprising a tubular profile made of aluminum alloy. The tubular profile includes an outer tube 1 and an inner tube 2 sleeved inside the outer tube 1. Both the outer tube 1 and the inner tube 2 are made of aluminum alloy. The inner tube 2 is detachably installed inside the outer tube 1. Specifically, the bottom of the outer tube 1 is provided with an extension rod, which is used to support the inner tube 2. The inner tube 2 can be installed on the extension rod by a snap-fit ​​method. The outer tube 1 and the inner tube 2 are coaxially arranged, and the height of the inner tube 2 is equal to the height of the outer tube 1. A wiring loop cavity is formed between the outer tube 1 and the inner tube 2 for wiring. A pre-embedded plate 3 is installed at the bottom of the outer tube 1. During construction, the pre-embedded plate 3 is buried underground.

[0024] The cable routing ring cavity is provided with a support positioning ring 4 that abuts against the outer tube 1 and the inner tube 2. The support positioning ring 4 has a through hole for the cable routing tube 7 to pass through. The cable routing tube 7 is set in the cable routing ring cavity and passes through the support positioning ring 4. There are at least two sets of support positioning rings 4, and at least two sets of positioning rings are distributed along the axial direction of the inner tube 2. A closed cavity is formed between any two adjacent sets of support positioning rings 4.

[0025] The corrosion resistance of the wiring ring cavity is increased by setting at least two sets of support positioning rings 4. Furthermore, the strength of the street light pole is increased to a certain extent by the structure of the outer tube 1 and the inner tube 2, making it less prone to deformation when subjected to external forces.

[0026] The support positioning ring 4 can be directly sleeved between the outer tube 1 and the inner tube 2 and fixed by welding. In some embodiments, preferably, the outer wall of the outer tube 1 has a limiting through hole 10, and a limiting support member 5 for supporting and positioning the support positioning ring 4 can be detachably installed in the limiting through hole 10. The limiting support member 5 is a support plate, which facilitates the positioning and support of the support positioning ring 4, and also facilitates the disassembly and installation of the support positioning ring 4. When disassembling the support positioning ring 4, the support positioning ring 4 can be disassembled by pulling a part of the support positioning ring 4 outward and shaking the support positioning ring 4 up and down.

[0027] To facilitate the shaking of the support positioning ring 4, preferably, the thickness of the limiting support 5 extending between the outer tube 1 and the inner tube 2 is less than the thickness of the portion where the limiting support 5 connects to the limiting through hole 10.

[0028] Specifically, a rubber sealing ring can be provided on the side of the support positioning ring 4 to increase the sealing performance.

[0029] Preferably, the outer wall of the inner tube 2 has a support groove 20, and the portion of the limiting support member 5 extending into the wiring ring cavity extends into the support groove 20, further increasing the support of the limiting support member 5 for the supporting positioning ring 4.

[0030] In order to better support the support positioning ring 4, and to support the outer tube 1 and the inner tube 2, preferably, the portion of the limiting support member 5 located in the wiring ring cavity is arranged to gradually slope downward from the end closer to the inner tube 2 to the end farther away from the inner tube 2.

[0031] Preferably, the limiting through hole 10 is opened in the horizontal direction, and the limiting support member 5 has a portion that contacts the limiting through hole 10, and this portion matches the limiting through hole 10.

[0032] In some preferred embodiments, the bottom of the outer pipe 1 is fitted with a pre-embedded plate 3 via a column 8. There is an internal pouring distance between the pre-embedded plate 3 and the inner pipe 2. A pouring pipe 11 extends from the inner pipe 2. The inner pipe 2 can be used to connect with the discharge end of the cement equipment. A sealing plate 9 is provided at the lower end of the inner pipe 2. The pouring pipe 11 is placed on the sealing plate 9 and communicates with the inner pipe 2. During the pouring process, the outer pipe 1, the inner pipe 2, and the pre-embedded plate 3 are first placed in the pre-embedded pit. Then, the discharge port of the external cement equipment is connected to the inner pipe 2 and sealed, thereby creating a downward force in the inner pipe 2. This ensures the positioning of the street light tube during the pouring process. Then, the cement is discharged through the pouring pipe 11 onto the pre-embedded plate 3. Since there is a pouring distance between the inner pipe 2 and the pre-embedded plate 3, cement is also poured between the inner pipe 2 and the pre-embedded plate 3, increasing the support of the inner pipe 2. At the same time, since the wiring ring cavity is located above the pre-embedded plate 3 and is opposite to the pre-embedded plate 3, some cement is also filled at the bottom of the wiring ring cavity, increasing the corrosion resistance of the street light tube.

[0033] Preferably, a sleeve 6 is installed on the pre-embedded plate 3. The sleeve 6 is fitted outside the outer pipe 1 and an outer pouring cavity is formed between the sleeve 6 and the outer pipe 1. The outlet of the pouring pipe 11 is opposite to the pouring cavity, which increases stability. The height of the sleeve 6 is higher than the bottom of the inner pipe 2, so that some cement can enter the inner pipe 2 and the space between the inner pipe 2 and the outer pipe 1.

[0034] Preferably, the outlet of the pouring pipe 11 is located between the outer pipe 1 and the pre-embedded plate 3, so that the cement discharged from the pouring pipe 11 impacts the part located between the sleeve 6 and the outer pipe 1.

[0035] Preferably, the sleeve 6 is vertically rotatably mounted on the pre-embedded plate 3, so that the sleeve 6 can rotate relative to the pre-embedded plate 3. Since the outlet of the pouring pipe 11 is opposite to the direction of the sleeve 6, the sleeve 6 can rotate relative to the pre-embedded plate 3 during the pouring process, thereby agitating the cement and allowing the cement to enter between the outer pipe 1 and the inner pipe 2, increasing the sealing performance and stability.

[0036] Preferably, the inner wall of the sleeve 6 is provided with a fan blade 12 extending into the pouring chamber. The cement discharged from the pouring pipe 11 impacts the fan blade 12, which in turn drives the sleeve 6 to rotate, further increasing the mixing of the cement and allowing the cement to enter between the outer pipe 1 and the inner pipe 2. Preferably, there are at least two sets of fan blades 12 and at least two sets of pouring pipes 11, with one set of pouring pipes 11 opposite to one set of fan blades 12. In order to increase the fluidity of the cement, the fan blade 12 is provided with a through hole.

[0037] It should be noted that, like existing street light tubes, the outer tube 1 has a groove 14 on its side wall to facilitate users climbing the street light tube.
