During the extension and retraction of the telescopic lamp pole 3, the operating rod 802 is pulled outward, which drives the slide plate 803 to approach one side of the fixed plate 801. The compression spring 804 is in a compressed state at this time, and the block 805 is close to the fixed plate 801. The carrying plate 800 can slide to the bottom end. At this time, the telescopic lamp pole 3 is not limited by the carrying plate 800 and can be smoothly extended and retracted. When the telescopic lamp pole 3 is in use and is extended to the top end, the carrying plate 800 is moved by the fixed plate 801. When the top of the carrying plate 800 is in contact with the When the bottom of the telescopic lamp pole 3 is reached, the two groups of blocks 805 are just aligned with the two groups of upper positioning holes 13. After the operating pull rod 802 is released, the compressed compression spring 804 can automatically return to its position, driving the block 805 to move toward the side of the fixed lamp pole 2 until the block 805 is connected to the corresponding upper positioning hole 13, thus fixing the position of the supporting plate 800. At this time, the supporting plate 800 supports the bottom of the telescopic lamp pole 3, thereby improving the stability of the combined smart street lamp during use. Among them, the block 805 can also be connected to the lower positioning hole 14. At this time, the supporting plate 800 is at the bottom, and the supporting plate 800 does not support the telescopic connecting rod 3.

[0038] Embodiment 2:

[0039] Reference Figure 7 This embodiment is different from the first embodiment in that: an anti-skid layer is provided on the outer surface of the block 805, a pull ring 806 is installed at the end of the operating rod 802 away from the block 805, and the hand-held end of the pull ring 806 is covered with an anti-skid rubber sleeve; the anti-skid layer plays an anti-skid role, improves the stability of the connection between the block 805 and the upper positioning hole 13 and the lower positioning hole 14, and improves the stability of the carrier plate 800 when the position is determined, the pull ring 806 facilitates the operation of the operating rod 802, and the anti-skid rubber sleeve plays an anti-skid role, preventing the hand from slipping when holding the pull ring 806.

[0040] Working principle: Before using the present invention, first, install all components, and the electrical ends of all electrical equipment are electrically connected to the external power supply and the electrical ends of the controller through wires. The smart street lamp pole is composed of a base 1, a fixed lamp pole 2, a telescopic lamp pole 3 and a connector 4. The smart street lamp is a modular type; when it is necessary to repair or replace the modular smart street lamp, the two sets of operating rods 802 are pulled outward, which drives the slide plate 803 to move closer to one side of the fixed plate 801. The compression spring 804 is in a compressed state at this time, and the block 805 is separated from the upper positioning The hole 13 is close to the fixed plate 801, and the bearing plate 800 can slide to the bottom position. At this time, the telescopic lamp pole 3 can be smoothly extended and retracted without restriction, and then the reduction motor 7 is started by the controller. The operation of the reduction motor 7 can drive the rotating gear 10 fixedly connected to the rotating shaft to rotate forward or reverse. Since the rotating gear 10 is meshed and connected with multiple groups of meshing grooves 11, after the telescopic lamp pole 3 passes through the limit of the inner cavity space of the fixed lamp pole 2, the telescopic lamp pole 3 can slide vertically in the fixed lamp pole 2 to adjust the height. When repairing or replacing, the telescopic lamp pole 3 is lowered to the lowest end;

[0041] Then, the stepper motor 501 on the folding component 5 works, that is, it drives the driving gear 503 fixedly connected to the bottom of the driving rod 502 to rotate. Since the driving gear 503 is meshed and connected with the mounting toothed disc 504, and the mounting toothed disc 504 is rotationally connected with the telescopic lamp pole 3 through the bearing, the mounting toothed disc 504 can drive the welded connector 4 to fold at an angle. When the lighting fixture 19 and the camera 21 are working normally, the connector 4 is distributed in a vertical direction. When the lighting fixture 19 and the camera 21 are repaired or replaced, the connector 4 is rotated to an angle that is convenient for repair and replacement.

[0042] When removing the lighting fixture 19 and the camera 21, the rotating rod 24 is rotated to rotate the cover 17 and move it away from the top of the connecting piece 16. After the top position of the connecting piece 16 is not restricted, it can be removed in the vertical direction. When the connector 4 is in normal use, the inner side of the cover 17 fits on the top of the connecting piece 16, which limits the vertical direction of the connecting piece 16. Among them, the two sets of side baffles 22 limit the positions of the two ends of the connecting piece 16 to prevent the lighting fixture 19 and the camera 21 from moving left and right. After the telescopic lamp pole 3 is lowered, the connector 4 can be bent to the side position, which is convenient for the maintenance and replacement of the lighting fixture 19 and the camera 21 on the combined smart street lamp, replacing the traditional maintenance and replacement with climbing tools, and effectively improving the maintenance efficiency.

[0043] When the telescopic lamp pole 3 is in use and extends to the top, the supporting plate 800 is moved by the fixing plate 801. When the top of the supporting plate 800 is in contact with the bottom of the telescopic lamp pole 3, the two groups of clamping blocks 805 are aligned with the two groups of upper positioning holes 13. After the operating pull rod 802 is released, the compressed compression spring 804 can automatically return to its original position, thereby driving the clamping block 805 to move toward the side of the fixed lamp pole 2 until the clamping block 805 is connected with the corresponding upper positioning hole 13, thereby fixing the position of the supporting plate 800. At this time, the supporting plate 800 supports the bottom of the telescopic lamp pole 3, thereby improving the stability of the combined smart street lamp during use.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
