Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to an LED smart street lamp based on a novel extended installation structure. Background Art

[0002] Smart street lights have become an important part of smart city construction with their versatility, efficiency and intelligence. Smart street lights can also serve as ports for the Internet of Things and play a greater role as a "complex". As the most densely distributed and evenly distributed information infrastructure in the city, driven by the construction of smart cities and base stations, smart street lights will gradually change from a single lighting function to a new type of public infrastructure.

[0003] Existing smart street lights have the problem of fixed installation positions of functional equipment, lack of flexibility and scalability. With the rapid development of technologies such as the Internet of Things, big data, and artificial intelligence, cities' functional requirements for smart street lights are also constantly changing and upgrading. However, due to their limitations, traditional smart street lights are often difficult to adapt to these new application scenarios and functional requirements, resulting in limited overall performance and effects of street lights. In addition, traditional smart street lights have deficiencies in heat dissipation design. Since street lights generate a lot of heat during use, if the heat dissipation effect is not good, it is easy to cause the street lights to overheat, which in turn affects their service life and performance. Overheating may also cause a series of safety hazards. In addition, traditional smart street lights lack effective monitoring of installation stability. When functional equipment becomes loose, it may not be discovered and handled in time, which will not only affect the performance of the equipment, but may also cause damage or fall off of the equipment, further exacerbating safety hazards.

The number of the mounting seats 4 is greater than or equal to three, at least one mounting seat 4 is connected to a video monitoring unit 20, and at least one mounting seat 4 is installed with an air quality sensor 21.

[0053] Working principle: The smart street lamp of the present application, as shown in the figure, the functional mechanism can be in a lifting state, a heat dissipation state and a detection state. In the lifting state, the rotating block is in a vertical state; in the heat dissipation state, the air outlet pipe is inserted into the air inlet of one of the mounting seats; in the detection state, at least one pressure sensor of the functional mechanism is pressed by the abutment plate of one of the mounting seats.

[0054] During installation, loosen the fixing bolts, and adjust the bolts to make the translation plate approach the rotating plate. The mounting seat can be inserted into the vertical slide groove through the slot, so that the mounting seat can be installed, and the mounting seat can be fixed by the locking bolt. Then rotate the movable plate unit, fix the fixing bolts, and then adjust the bolts to make the translation plate abut against the mounting seat. The mounting seat can locate the installation position of the mounting seat through the cooperation of the locking bolts and the positioning holes, and the cooperation of the positioning protrusions and the through-holes, and can also support and fix the mounting seat.

[0055] Furthermore, the lifting mechanism can be lifted and lowered under the drive of the top electric winding device and the bottom electric winding device, and in the lifting state, the functional mechanism does not affect the lifting and lowering of the lifting mechanism. The first connecting plate and the second connecting plate can also guide and limit the lifting mechanism. Furthermore, when the temperature inside the micro base station or the LED lamp holder is too high, the air outlet duct can be inserted into the air inlet of the corresponding mounting seat to achieve high-power rapid active heat dissipation. In addition, each mounting seat can be tested to see if it is loose. Figure 7 As shown, after the lifting mechanism reaches the detection position, the electric telescopic rod is extended, and its movable end is pressed against the second connecting plate, thereby further locking the position of the lifting mechanism. The driving motor drives the rotating block to rotate, and the pressure sensor of the semi-cylindrical column is used to abut the abutment plate at the mounting seat. If the mounting seat is not loose, there is almost no transition value between the measured value of the pressure sensor from zero to the pressure generated by the driving motor driving the rotating block. If the mounting seat is loose, the measured value of the pressure sensor will have an intermediate value between zero and the maximum value for a certain period of time (the intermediate value is mainly caused by the downward pressure of the gravity of the mounting seat when the semi-cylindrical protrusion lifts the mounting seat upward slightly when the mounting seat is loose, and the lifting process). Therefore, according to the measured value of the pressure sensor, it is possible to detect whether each mounting seat is loose.

[0056] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
