[0026] The utility model provides Figure 1-Figure 5 The street lamp with automatic brightness adjustment based on the road traffic flow is applied to the gantry, and the high stability support characteristics of the gantry are used to improve the purpose of supporting multiple lighting mechanisms 2 at the same time. In addition, several cameras and processors are installed on the gantry, and the cameras upload the photos or videos taken to the processor, and the processor obtains the change of traffic flow through a series of algorithms, and uploads the results to the control unit, and the control unit controls the following structure according to the change.
[0027] Example 1
[0028] In one case of this embodiment, the push-pull mechanism 1 has a linear push capability, such as a telescopic cylinder structure such as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, which can use its own telescopic rod to drive the components to telescopically move. Due to cost constraints, a pneumatic cylinder or an electric cylinder is preferred.
[0029] The cylinder seat of the telescopic cylinder is fixed on the gantry, a telescopic rod is slidably connected in the cylinder seat, a controller for controlling the operation of the telescopic rod is arranged in the cylinder seat, and the controller is electrically connected to the control unit.
[0030] In another situation of this embodiment, the push-pull mechanism 1 includes a motor 11 and a screw rod 12. The motor 11 is installed on the gantry and electrically connected to the mains. The output shaft of the motor 11 is fixedly connected to the screw rod 12. The housing of the lighting mechanism 2 farthest from the motor 11 is threadedly connected to the motor 11. The housing of the lighting mechanism 2 closest to the motor 11 is rotationally connected to the screw rod. The housings of the remaining lighting mechanisms 2 can be slidably mounted on the screw rod 12. The housings of two adjacent lighting mechanisms 2 are connected by a retractable connecting piece 5. The housings of the lighting mechanisms 2 can be slidably connected to the gantry.
[0031] Preferably, the retractable connecting member 5 is a rigid folding rod, including a plurality of rods hinged end to end in sequence, and the ends of the rods at the two ends are hinged to the corresponding housings of the illumination mechanism 2 respectively.
[0032] Preferably, the retractable connecting member 5 is a flexible rope, and both ends of the flexible rope are fixedly connected to the corresponding outer shell of the lighting mechanism 2 respectively.
[0033] Therefore, whether using a rigid part or a flexible part, the farthest lighting mechanism 2 can be driven to move first under the driving action of the thread, and then the subsequent lighting mechanisms 2 can be driven to follow the movement through the pulling action of the retractable connecting member 5, so as to achieve the purpose of gradually unfolding several lighting mechanisms 2. Similarly, when it is necessary to retract several lighting mechanisms 2, the screw rod 12 is turned over, and the farthest lighting mechanism 2 is used to squeeze the subsequent lighting mechanisms 2 in sequence through the driving action of the thread, so as to gradually retract the lighting mechanisms 2.
[0034] The above structure enables the purpose of unfolding or folding a plurality of illumination mechanisms 2, thereby achieving the purpose of changing the illumination range of the illumination mechanism 2.
[0035] Example 2
[0036] On the basis of the above structure, a pressure swing mechanism 3 is also provided, including a motor 2 31 and a pressure plate 32. The motor 2 31 is installed on the gantry, and the output shaft of the motor 2 31 is fixedly connected to the pressure plate 32; the lighting mechanism 2 includes a street lamp body 21 and a lamp holder 22. The street lamp body 21 includes all working components required for a lamp when in use. The outer shell of the street lamp body 21 is elastically rotatably connected to the lamp holder 22, and the back of the street lamp body 21 is located on the rotation path of the pressure plate 32. When the motor 2 31 controls the pressure plate 32 to rotate and squeeze the street lamp body 21 under the drive of the control unit, the street lamp body 21 will change the viewing range during the swinging process, so as to achieve the purpose of further adjusting the lighting range.
[0037] Example 3
[0038] On the basis of the above structure, a power connection mechanism 4 is also provided, through which the illumination mechanism 2 is electrically connected to the mains. Based on the operation of the power connection mechanism 4, the connection reliability between the mobile street lamp body 21 and the mains is improved.
[0039] In one case of this embodiment, the power supply mechanism 4 is a plurality of bundles of wires, and a plurality of street lamp bodies 21 are electrically connected to the mains through corresponding wires, and each wire is in a loose state.
[0040] In another situation of this embodiment, the power supply mechanism 4 includes a shell 41 and a conductive sheet 1. The shell 41 is installed on the gantry, and the conductive sheet 1 is installed on the shell. The number of the conductive sheets 1 is equal to the number of the street lamp bodies 21. The lamp holder 22 is fixed with a conductive sheet 2. Both the conductive sheet 1 and the conductive sheet 2 are electrically connected to the AC power. The conductive sheet 1 is located on the moving path of the conductive sheet 2. When the conductive sheet 1 and the conductive sheet 2 are in contact, the circuit is connected and the street lamp body 21 is energized.
[0041] Furthermore, a slide groove 42 is opened on the shell 41, and the number of the slide grooves 42 is equal to the number of the conductive sheet 1. The conductive sheet 1 with a smaller length is fixed in the corresponding slide groove 42 with a longer length. A connecting rod 43 is arranged between the lamp holder 22 and the slide groove 42. One end of the connecting rod 43 is fixedly connected to the lamp holder 22 and the other end is slidably connected to the slide groove 42. The conductive sheet 2 is installed on the end face of the connecting rod 43 close to the slide groove 42.
[0042] Through the above structure, not only the stability of the electrical connection can be improved, but also the purpose of powering on only when the street lamp body 21 moves to the specified position can be achieved, thereby improving the operability of turning on or off the street lamp bodies 21 one by one, and realizing another control method of successively increasing or decreasing the lighting range and light intensity.
[0043] In summary, the main improvement of this design is that it utilizes the linear driving capability of the push-pull mechanism 1 to push a number of street lamp bodies 21 to move in sequence, and combines it with the ability of the swing mechanism 3 to control the flipping of the street lamp body 21, thereby achieving control over the illumination range of the street lamp body 21 in two degrees of freedom, thereby improving the control diversity and reliability of the illumination range of the smart street lamp using this structure.
[0044] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
