Description

Technical Field

[0002] Smart street lights integrate some functional devices on street lights, making them more functional. With the acceleration of urbanization and the advancement of smart city construction, smart street lights, as an important part of smart cities, will continue to grow in market demand.

[0003] Some existing smart street lights integrate multiple functions, resulting in too many external devices, the overall shape is not simple enough, and the coordination with the urban landscape is poor. Some street lights have a single function and do not have a spray function. In arid and dusty areas, the spray function can effectively reduce dust in the air and improve air quality. It can also play a cooling role in hot weather. However, many existing smart street lights are not equipped with this function, which limits their application in environmental improvement. Some street lights do not have the cleaning function of the lighting unit, resulting in the problem of reduced lighting effect due to dust and dirt accumulation on the light-transmitting mirror after the street lights have been used for a period of time. In addition, the heat dissipation effect of some lighting units is not good, which affects the lighting effect and service life of the street lights. Summary of the invention

[0027] Thereby, the drive motor is stably installed and fixed.

[0028] Furthermore, the end of the transfer pipe has a first flange, and the end of the water inlet pipe has a second flange connected to the first flange.

[0029] Furthermore, the first side plate unit has a water inlet pipe installation channel for installing the water inlet pipe; the second side plate unit has a wire threading channel.

[0030] This makes it easy to install the water inlet pipe and wires. During installation, the water inlet pipe and wires will extend into the interior of the light pole.

[0031] Furthermore, the top ends of the first lower side plate and the second lower side plate are both curved; the radius of the curved surface of the top end of the first lower side plate, the inner diameter of the first curved panel, the radius of the curved surface of the top end of the second lower side plate and the inner diameter of the second curved panel are equal.

In some cases, the water inlet pipe can also be multiple pipes spliced ​​together, for example, two pipes are spliced ​​together, one at the lamp holder unit and one in the lamp pole, and the joints of the two pipes are fixedly connected. Of course, flanges can also be installed at the joints of the two pipes, and the two pipes are connected through flanges.

[0038] Furthermore, the lamp pole includes a bottom flange, a lamp holder connected to the flange, and a rod connected to the lamp holder.

[0039] Furthermore, the LED smart street light can be in a heat dissipation mode, in which the cleaning nozzle is in a vertical state, the cooling fan is turned on, and the heat dissipation airflow generated by the cooling fan passes through the motor mounting groove, a part of which passes through the first connecting groove and the first groove part to enter the first air inlet, and the other part passes through the second connecting groove and the second groove part to enter the second air inlet.

[0040] Furthermore, in the heat dissipation mode, all the first nozzles are shielded by the first arc panel, and all the second nozzles are shielded by the second arc panel.

[0041] Furthermore, in the heat dissipation mode, the insertion rod passes through the card slot.

[0044] Furthermore, the LED smart street light can be in a mounting plate use mode, in which the U-shaped rod abuts against the mounting plate.

[0045] Furthermore, in the use mode of the mounting plate, the mounting plate is in a horizontal state.

[0046] This allows for easy access to components at the mounting plate.

[0047] Beneficial effects:

[0048] 1. The street lamps of this application are multifunctional and integrate various sensors, information display, broadcasting, monitoring and other functions, thus providing strong support for building smart cities, improving urban management levels and enhancing public service capabilities.

[0049] 2. The street lamp of the present application has a spray function, and can spray into the air through the first nozzle and the second nozzle, thereby helping to improve the air humidity in the city and create a more pleasant living environment for citizens.

[0073] like Figure 3 As shown, the heat dissipation airflow generated by the heat dissipation fan at this time enters the motor mounting groove, is split into the first connecting groove and the second connecting groove, respectively enters the first air inlet of the first lamp holder shell through the first groove portion, and enters the second air inlet of the second lamp holder shell through the second groove portion.
