Description

Technical Field

[0001] The present invention relates to the technical field of power auxiliary equipment, and in particular to a composite material street code. Background Art

[0002] From two-line street codes to multi-line street codes, usually the most common way to install low-voltage lines (low-voltage output side of the transformer) in rural areas is through cement poles, but it is inconvenient to plant cement poles on the streets in towns, so street codes came into being.

[0003] The existing mounting frame of the street code has poor corrosion resistance. When in contact with air for a long time, the mounting frame is easily corroded, which leads to the loosening of the street code, and does not meet the use needs of existing users. At the same time, during the long-term use of the street code, the power supply circuit is in a floating state for a long time, which causes the street code components to become loose or broken.

[0004] Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the invention

[0014] Further, reinforcing holes are arranged at equal intervals along the length direction of the side wings.

[0015] Further, a plurality of connection holes corresponding to the support rods are arranged at equal intervals along the length direction on the top surface of the main body portion. One end of the support rod is inserted into the connection hole and is welded to the main body portion.

[0016] Further, one end of the support rod passing through the connection hole extends towards the concave portion to form an extension portion. A reinforcing rib connected to the extension portion is further provided inside the concave portion.

[0034] The embodiment of the patent of the present invention provides a composite material street code. By arranging a composite layer 500 coating composed of a composite material on the seat body, the support rod 200 and the iron core 300, the corrosion resistance of the street code during use can be effectively improved. At the same time, the technical solution can improve the stability of the street code, avoiding the loosening of various components of the street code caused by the shaking of the wires during long-term use.

[0035] Specifically, Figure 1-3 As shown, a composite material street code provided by an embodiment of the present invention includes: a base 100, a support rod 200, an iron core 300, an insulator 400 and a composite layer 500 for coating, wherein the base 100 includes a main body 110, and both side edges of the main body 110 are formed with side wings 120 extending along the width direction; there are multiple support rods 200, and the multiple support rods 200 are arranged side by side at equal intervals along the length direction of the main body 110, one end of which is connected to the main body 110, and the other end extends vertically away from the main body 110, and each support rod 200 is provided with a mounting hole 201, and the axes of the multiple mounting holes 201 are located at On the same straight line parallel to the main body 110; penetrated into all the installation holes 201, and anti-dropping parts 310 are formed at both ends; the insulator 400 includes a plurality of insulators, and at least is mounted on the part of the iron core 300 located between two adjacent support rods 200; the composite layer 500 is coated on the surface of the base 100, the support rod 200 and the iron core 300, and the composite layer 500 includes a first protective layer 510 and a second protective layer 520 coated in sequence, the first protective layer 510 includes an anti-corrosion galvanized layer 511 and an anti-aging passivation layer 512, and the second protective layer 520 includes a phenolic resin nano-spray paint layer 521 and a polyethylene powder dipping layer 522. In the present technical solution, an anti-corrosion galvanized layer 511, an anti-aging passivation layer 512, a phenolic resin nano-spray paint layer 521 and a polyethylene powder dipping insulation layer 522 are provided, which can improve the corrosion resistance, electrical insulation resistance, dust and water resistance of the I-shaped base of the support frame and the separating support column itself, further improve the service life of the street code, and meet the service life of existing users.

[0036] Through the above technical solution, a composite layer 500 is coated on the surfaces of the base 100, the support rod 200, and the iron core 300, so as to provide corrosion protection for the main components of the street clamp, ensuring that it can withstand the erosion of natural environments such as rain and sunlight during long-term outdoor installation and guaranteeing the service life of the street clamp. During the installation of the street clamp, the base 100 is fixed on the wall or column, and the support rod 200 is supported by the main body portion 110 to avoid direct contact between the support rod 200 and the wall or column, thereby preventing the erosion of the support rod 200. In addition, the side wings 120 are provided on both sides of the base 100 to play a stabilizing role and ensure the stability of the base 100 after installation. In this embodiment, there can be multiple insulation installation positions, which can be set at the position of the iron core 300 between the two support columns or at the position of the support rod 200 between the base 100 and the iron core, so as to meet the use requirements of various scenarios.

[0037] In this embodiment, a concave portion 111 recessed from the surface is provided on one side of the main body portion 110, so that the cross-section of the base 100 is in a "ji" shape, and a plurality of equally spaced fixing holes 112 are evenly opened along the length direction of the main body portion 110. During the installation of the street clamp, by setting the main body portion 110 in a "ji" shape structure, the distance between the support rod 200 and the installation surface such as the wall can be further increased or decreased, reducing the situation of mutual contact. At the same time, during the shaking process, the side walls on both sides of the main body portion 110 can absorb the shaking amount, thereby preventing the shaking amount from directly acting on the connection position between the base 100 and the wall. During the installation process, fixing holes 112 are provided on the top surface of the main body portion 110, and installation bolts pass through the fixing holes 112 to lock the main body portion 110 on the wall, improving the installation stability of the base 100.

[0038] In this embodiment, in order to further improve the firmness of installing the street clamp, equally spaced reinforcement holes 121 are opened along the length direction of the side wing 120. The reinforcement holes 121 also allow installation bolts to pass through and connect with the installation surface such as the wall, so that the side wing 120 can be closely attached to the wall under the clamping of the installation bolts, ensuring the stability of the base 100.

[0039] In this embodiment, in order to improve the firmness of the connection between the base 100 and the support rod 200, a plurality of connection holes 113 corresponding to the support rod 200 are provided at equal intervals on the top surface of the main body 110 along its length direction, and one end of the support rod 200 is inserted into the connection hole 113 and welded to the main body 110. In other words, the support rod 200 is inserted into the connection hole 113 in advance, and then the main body 110 and the support rod 200 are welded. At this time, since the support rod 200 is already in the connection hole 113, there is a mutual compressive force between the support rod 200 and the inner wall of the connection hole 113. Then, welding is performed, which can ensure the reliability and firmness of the connection between the support rod 200 and the main body 110.

[0040] In this embodiment, in order to further improve the reliability of the connection between the support rod 200 and the base 100, one end of the support rod 200 passing through the connection hole 113 extends toward the inner recess 111 to form an extension portion 202, and a reinforcing rib 114 connected to the extension portion 202 is also provided inside the inner recess 111. The extension portion 202 is formed with a through hole for the reinforcing rib 114 to pass through, and the reinforcing rib 114 is located at both ends of the extension portion 202 and is fixedly connected to the inner wall of the inner recess 111. In other words, by extending the bottom of the support rod 200, the length of the support rod 200 in the inner recess 111 is increased, the balance of the support rod 200 is improved, and the extension portion 202 is reinforced by the reinforcing rib 114, so that the firmness of the support rod 200 installed on the base 100 can be improved.

[0041] In this embodiment, if Figure 1-3 As shown, at least one end of the reinforcing rib 114 passes through the inner wall of the inner concave portion 111 and extends to the outside to form a reinforcing end 115, and the reinforcing end 115 is welded to the outer wall of the main body 110. By extending at least one end of the reinforcing rib 114 to the outside of the inner concave portion 111 and forming the reinforcing end 115, and then welding it to the outer wall of the main body 110, the strength of the reinforcing rib 114 can be increased, thereby increasing the firmness of the support rod 200. In this embodiment, the reinforcing rib 114 can be formed by riveting the main body 110 and the extension portion 202 with rivets, and the rivet head and tail located on the outside of the main body 110 are welded, so as to ensure that the rivet can be stably connected to the main body 110 without loosening.

[0042] In this embodiment, the support rod 200 is a circular tube structure, and the extension part 202 is provided with an oblate structure with a different arc from the support rod 200, so that the width of the extension part 202 is greater than the width of the support rod 200 located on the upper side of the connection hole 113. By flattening the extension part 202, the extension part 202 and the connection hole 113 can be clamped together during installation, and a certain pressure force is generated between them. Through the internal stress between the support rod 200 and the main body 110, it is ensured that the support rod 200 and the main body 110 can be stably connected.

[0043] In this embodiment, in order to prevent the insulator 400 from moving along the axial direction of the installed rod when installing it, thereby causing a large impact force on the street code and affecting the stability of the street code, the support rod 200 also includes a reinforcement sleeve 210. A blind hole is formed at one end of the reinforcement sleeve 210, in which the end of the support rod 200 away from the base 100 is sleeved, and a through hole 212 is opened radially along the reinforcement sleeve 210 for the iron core 300 to pass through.

[0044] In a further technical solution, the portion of the circumferential surface of the reinforcement sleeve 210 where the through hole 212 is provided is formed with a protrusion 213 extending toward the adjacent reinforcement sleeve 210, and the through hole 212 penetrates the protrusion 213 along the length direction of the protrusion 213 for the iron core 300 to pass through. By providing the protrusion 213, the spacing between the two support rods 200 can be reduced, so that the insulator 400 located between the two support rods 200 can be limited, avoiding excessive movement along the axial direction of the iron core 300, reducing the movement amplitude of the insulator 400, ensuring the jitter and vibration of the street code, and ensuring the stability of the street code.

[0045] In this embodiment, in order to facilitate the installation of the insulator 400 and the disassembly of the iron core 300, at least one anti-dropping member 310 on the iron core 300 is detachably connected to one end of the iron core 300. In this embodiment, one of the anti-dropping members 310 can be a protrusion fixedly assembled at one end of the iron core 300, and the other anti-dropping member 310 can be a nut threadedly connected to the iron core 300.

[0046] For those skilled in the art, various other corresponding changes and deformations can be obtained based on the structure and principle disclosed by the present invention, and all of these changes and deformations belong to the protection scope of the present invention.
