[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The core of the present invention is to provide a segmented smart lamp pole, in which two adjacent lamp pole units are connected by an interference fit between a guide column and a guide groove. The connection structure is simple and easy to disassemble and assemble, thereby realizing the rapid disassembly and assembly of the smart lamp pole.

[0029] The segmented smart lamp pole provided by the present invention includes a plurality of lamp pole units 10. A snap-fit structure is provided between two adjacent lamp pole units 10. The snap-fit structure includes a guide column 2 and a guide groove 1 respectively provided at the connecting ends of the two lamp pole units 10. The guide column 2 is snap-fitted into the guide groove 1 by interference fit.

[0030] Please refer to Figure 1 The smart lamp pole is formed by splicing several lamp pole units 10, and various functional modules 20 such as lighting fixtures, solar panels, monitoring probes, etc. are installed on each lamp pole unit 10. Considering the maintenance and replacement of the functional modules 20, the functional modules 20 and the lamp pole units 10 are usually set to be detachably connected.

[0031] For example, the lamp pole barrel of the lamp pole unit 10 is provided with a functional connection port 4 for detachable connection with the functional module 20, and the mounting seat of the functional module 20 is connected to the functional connection port 4 through a functional connector; the functional connector is usually configured as a connecting screw, a connecting pin, etc.

[0032] Taking into account the wiring requirements of different functional modules 20, the corresponding lamp pole unit 10 structure can be customized according to the specific functions of the functional module 20;

[0033] However, in order to improve the versatility of the lamp pole unit 10, it is preferred to provide a wire hole 3 in the center of the connecting end plate of the lamp pole unit 10. The wire hole 3 is used for the passage of the ring bus, power interface, and data interface. The size of the wire hole 3 is determined according to the size of the data line, power line and other connecting lines of each functional module 20 in actual production to prevent the wire hole 3 from being scratched against the connecting line, causing the insulation layer on the surface of the connecting line to peel off, thereby affecting the electrical safety of the lamp pole unit 10.

[0034] Preferably, an insulating elastic ring can be provided inside the wire hole 3. The insulating elastic ring is used to separate the inner wall of the wire hole 3 and the insulating layer of the connecting wire, and can restrain the horizontal shaking of the connecting wire in the wire hole 3, which is beneficial to improving the service life of the connecting wire and ensuring the electrical safety of the lamp pole unit 10.

[0035] Two adjacent lamp pole units 10 are connected by a snap-fit structure. In order to ensure a stable and reliable connection between the two adjacent lamp pole units 10, the two adjacent lamp pole units 10 are usually connected by at least three snap-fit structures according to the three-point circle principle.

[0036] The snap-fit structure includes a guide column 2 and a guide groove 1 respectively provided at the connecting ends of the two lamp pole units 10. The guide column 2 and the guide groove 1 are interference fit to prevent relative misalignment of the two adjacent lamp pole units 10 after assembly, thereby ensuring the connection stability and reliability of the connection of the lamp pole units 10.

[0037] In this embodiment, two adjacent lamp pole units 10 are snap-connected by the interference fit of the guide column 2 and the guide groove 1. Compared with the existing welding connection or bolt connection, the connection structure is simple and easy to disassemble and assemble, which can realize the rapid disassembly and assembly of the smart lamp pole and significantly shorten the assembly time required.

[0038] Preferably, a sealing ring may be provided between two adjacent lamp pole units 10 , and at least one of the connecting ends of the two adjacent lamp pole units 10 may be provided with a sealing groove for installing the sealing ring.

[0039] The sealing ring can be specifically set as a rubber sealing ring, a silicone sealing ring, etc. In order to ensure the waterproof performance and sealing performance between two adjacent lamp pole units 10, in a specific embodiment, the sealing ring can reach the IP67 protection level when the compression amount is ≥30%.

[0040] The shape of the sealing groove is adapted to the shape of the sealing ring. Considering the processing cost of the connecting end plate of the lamp pole unit 10, the connecting end plate is usually provided with only one circle of sealing groove.

[0041] The above-mentioned sealing groove can be a groove structure provided on the connecting end plate of the lamp pole unit 10, or a sealing edge provided on the outer edge of the connecting end plate of the lamp pole unit 10, and the sealing edge is lower than the central area of the connecting end plate for installing the guide column 2 or the guide groove 1.

[0042] Based on the above examples, please refer to Figure 2 , the lamp pole unit 10 includes a lamp pole cylinder and a connecting end plate, the connecting end plate is connected to the end surface of the lamp pole cylinder through a connecting piece, and the connecting piece is evenly arranged along the circumferential direction of the lamp pole cylinder;

[0043] The connecting end plate is provided with at least one guide column 2 or at least one guide groove 1, and the guide columns 2 or guide grooves 1 are evenly arranged along the circumferential direction of the connecting end plate.

[0044] Among them, at least one end of the lamp pole cylinder is provided with a connecting end plate. When the lamp pole unit 10 is the lamp pole unit 10 at the bottom of the smart lamp pole, one end of the lamp pole cylinder is provided with a grounding fixing seat for installing a grounding bolt to connect the smart lamp pole and the ground, and the other end is provided with a connecting end plate;

[0045] When the lamp pole unit 10 is the lamp pole unit 10 at the top or the middle of the smart lamp pole, both ends of the lamp pole cylinder are provided with connecting end plates.

[0046] The connecting end plate is connected to the end face of the lamp pole barrel through a connecting piece, which can be specifically set as a connecting screw, a connecting pin, etc.; in order to make the connection and tightening force of the lamp pole unit 10 in all directions roughly the same, the connecting pieces need to be evenly arranged along the circumferential direction of the lamp pole barrel.

[0047] The guide posts 2 or guide grooves 1 are both provided on the connecting end plates. In order to evenly distribute the connection and fastening force of the clamping structure on two adjacent lamp pole units 10 in all directions, the guide posts 2 or guide grooves 1 can be evenly provided along the circumferential direction of the connecting end plates.

[0048] In this embodiment, the lamp pole unit 10 is a detachable connection between the lamp pole cylinder and the connecting cylinder, which facilitates the internal wiring of the lamp pole unit 10. Compared with the lamp pole unit 10 being an integrated structure, it is helpful to shorten the assembly time required for the lamp pole unit 10 and the entire smart lamp pole.

[0049] The connecting pieces and the snap-fit structures are evenly distributed along the circumference of the lamp pole units 10 , ensuring that the forces on the lamp pole units 10 are relatively even in all directions, which is beneficial to improving the connection stability and reliability between the lamp pole units 10 .

[0050] Based on the above examples, please refer to Figure 4 and Figure 5 , the guide groove 1 is provided on the connecting end plate through the guide groove mounting plate 5, and the guide groove mounting plate 5 is connected to the connecting end plate through the guide groove connector;

[0051] The guide groove connection is usually provided as a connection screw or a fastening pin, e.g. Figure 4As shown, the guide groove mounting plate 5 is evenly provided with four bolt mounting holes for mounting connecting screws along the circumferential direction of the guide groove 1 .

[0052] On the basis of the above embodiment, the structure of the guide column 2 is defined. The guide column 2 includes a cylindrical section, a frustum section and a hemispherical section. The small end of the frustum section is connected to the cylindrical section, and the large end of the frustum section is connected to the hemispherical section. The diameter of the hemispherical section is larger than the inner diameter of the guide groove 1. Figure 3 As shown, an interference fit between the guide column 2 and the guide groove 1 is achieved.

[0053] On the basis of the above embodiment, in order to prevent the guide column 2 from escaping from the guide groove 1 , at least two fixing plates 7 may be provided in the guide groove 1 along the circumferential direction, and the fixing plates 7 are connected to the inner circumference of the guide groove 1 via springs 6 .

[0054] The spring 6 can be arranged along the radial direction of the guide groove 1, that is, one end of the spring 6 is arranged vertically or obliquely on the inner circumference of the guide groove 1, and the other end of the spring 6 is connected to the fixing plate 7;

[0055] The spring 6 can also be arranged along the axial direction of the guide groove 1. The guide groove 1 is provided in the center of the guide groove mounting plate 5. The lower end of the guide groove mounting plate 5 is provided with a spring mounting seat 8. A spring 6 is provided in the guide groove 1. A fixing plate 7 is provided at one end of the spring 6. The shape of the fixing plate 7 is adapted to the shape of the guide column 2 so that after the guide column 2 is snapped into place, the fixing plate 7 can limit the axial movement of the guide column 2. The other end of the spring 6 is abutted or connected to the spring mounting seat 8 so that the pre-tightening force of the spring 6 can be used to realize the effective snap-fit positioning of the fixing plate 7 on the guide column 2.

[0056] Please refer to Figure 6 , the guide groove mounting plate 5 includes a mounting top plate and a mounting sleeve, the upper end of the mounting sleeve is threadedly connected to the mounting top plate, and the lower end of the mounting sleeve is threadedly connected to the spring mounting seat 8 to facilitate disassembly and replacement of the spring 6;

[0057] Of course, the mounting top plate and the mounting sleeve, as well as the mounting sleeve and the spring mounting seat 8 may be connected by common connecting pieces such as connecting screws and connecting pins.

[0058] In this embodiment, the preload force of the spring 6 is used in conjunction with the fixing plate 7 to perform axial guiding and limiting on the guide column 2, thereby preventing the guide column 2 from disengaging from the guide groove 1, further improving the connection stability and reliability of the snap-fit unit of the lamp pole unit 10, and thereby improving the installation stability and reliability of the smart lamp pole.

[0059] Preferably, please refer to Figure 2In order to facilitate the separation of the guide column 2 and the guide groove 1, an inspection port 9 can be provided on the outer periphery of the lamp pole cylinder of the lamp pole unit 10, and the inspection port 9 is provided with an inspection plate, which is connected to the lamp pole cylinder through an inspection connector; the inspection connector can be specifically set to common connectors such as connecting screws and connecting pins.

[0060] When it is necessary to dismantle the connection between two adjacent lamp pole units 10, remove the inspection plate and disconnect the spring mounting seat 8 from the guide groove mounting plate 5 through the inspection port 9, so that the spring 6 and the fixing plate 7 lose their axial limiting effect on the guide column 2, and then apply a relative separation pulling force to the two adjacent lamp pole units 10 to disengage the guide column 2 from the guide groove 1, thereby separating the two adjacent lamp pole units 10.

[0061] On the basis of the above embodiments, considering that the lamp pole unit 10 is mostly a thin-walled part, in order to improve the bending strength of the smart lamp pole, the lamp pole unit 10 can be provided with at least one reinforcement ring in the axial direction inside the lamp pole barrel, and the reinforcement ring is used to enhance the bending strength of the lamp pole barrel.

[0062] The reinforcement ring is usually made of high carbon steel with high bending strength and can be embedded in the lamp pole cylinder of the lamp pole unit 10 by welding or integral processing;

[0063] The number and spacing of the reinforcement rings are determined by calculation based on the material and wall thickness of the lamp pole unit 10 and the material and size of the reinforcement rings in actual production according to the design bending strength requirements.

[0064] In addition, a reinforcing rib or reinforcement bar may be provided between two adjacent reinforcing rings, and the reinforcing rib or reinforcement bar extends along the axial direction of the lamp pole unit 10 .

[0065] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
