[0034] Embodiment 2:

[0035] On the basis of the first embodiment, in this embodiment, most of the heat on the rear side of the inner part of the support plate 83 is absorbed by the heat absorbing vertical pipe 81 and dissipated outwardly, and at the same time, the external air will enter the hollow structure of the heat absorbing vertical pipe 81 to ventilate and cool it, and the heat sink 82 can also further increase the heat dissipation area of ​​the heat absorbing vertical pipe 81, thereby avoiding the easy accumulation of heat on the rear side of the inner part of the support plate 83, which will cause the back of the outdoor display screen 9 to overheat.

[0036] The support assembly 8 includes a heat absorbing vertical pipe 81, a support plate 83, an installation cavity 84 and a fixed frame 85. The support plate 83 is fixedly connected to the upper side of the left end surface of the support lamp pole 3. The support plate 83 is connected to the support lamp pole 3 by welding. The support plate 83 will support the outdoor display screen 9. The rear side of the support plate 83 is fixedly connected to a heat absorbing vertical pipe 81. There are three groups of heat absorbing vertical pipes 81 fixedly connected, and the specifications of the three groups of heat absorbing vertical pipes 81 are the same. The heat absorbing vertical pipe 81 is a hollow structure. The three groups of heat absorbing vertical pipes 81 with a hollow structure can not only absorb most of the heat on the rear side of the support plate 83, but also facilitate external air to enter the heat absorbing vertical pipe 81 for ventilation and cooling.

[0037] A mounting cavity 84 is provided on the front end surface of the support plate 83, and the mounting cavity 84 matches the outdoor display screen 9. The mounting cavity 84 facilitates the outdoor display screen 9 to be embedded in the front end surface of the support plate 83 for use.

The upper and lower sides of the annular side surface of the heat absorbing vertical pipe 81 are fixedly connected with heat sinks 82. There are multiple heat sinks 82 fixedly connected, and the multiple heat sinks 82 have the same specifications. The multiple heat sinks 82 can further increase the heat dissipation area of ​​the heat absorbing vertical pipe 81, so that the heat dissipation effect of the heat absorbing vertical pipe 81 is better. The heat absorbing vertical pipe 81 and the heat sink 82 are both made of high-conductivity copper, and the heat absorbing vertical pipe 81 and the heat sink 82 made of high-conductivity copper have good thermal conductivity.

[0038] Working principle: During the use of this device, the power regulator 11 can enable the street light controller 12, the intelligent temperature control switch 26, the intelligent camera and the outdoor display screen 9 to work normally under the rated working voltage. The street light controller 12 can control the automatic switch of the LED street light head 7 by time control or remote control to achieve the purpose of saving power and optimizing power supply. The wireless camera 4 enables the device to have shooting capabilities, and the outdoor display screen 9 will display the required screen when working, and the traffic sign 6 enables the device to have traffic indication capabilities, thereby making the device more intelligent and diversified; at the same time, when the intelligent temperature control switch 26 detects through the temperature sensor 23 that the temperature value inside the protection cavity 27 exceeds the preset maximum value, the intelligent temperature control switch 26 will energize the cooling fan 24 to work, and at this time the protection cavity 27 will suck the external air through the connecting cavity 21 and the air inlet cavity 22, and the inside of the connecting cavity 21 The hot air will be discharged to the outside through the through cavity 28 and the air outlet elbow 25, so as to actively ventilate and dissipate heat for the protection cavity 27, so as to avoid the heat accumulation inside the protection cavity 27 affecting the service life of the power stabilizer and the street lamp controller 12. When the intelligent temperature control switch 26 detects through the temperature sensor 23 that the temperature value inside the protection cavity 27 is lower than the preset minimum value, the cooling fan 24 will be stopped to reduce the power consumption of the device. During the use of the outdoor display screen 9, heat will be generated on its rear end face and transferred to the rear side of the support plate 83. At this time, the three groups of heat absorbing vertical pipes 81 will absorb most of the transferred heat. At the same time, the external air will also pass through the heat absorbing vertical pipe 81 with a hollow structure to ventilate and cool it, and the heat sink 82 can also further increase the heat dissipation area of ​​the heat absorbing vertical pipe 81, so as to avoid the heat accumulation on the rear side of the support plate 83 and cause the back of the outdoor display screen 9 to overheat.
