DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 4 As shown, the technical solution adopted in this specific embodiment is: it includes a main frame 3, a solar panel 1 is installed on the top of the main frame 3, an LED display screen 6 is installed on the surface end of the main frame 3, and a supporting base plate 4 is provided at the bottom of the main frame 3, the main frame 3 includes a protective frame 32, an air supply fan 31 is installed above the surface end of the protective frame 32, and the LED display screen 6 is installed in the middle of the protective frame 32, a heat sink 36 is installed on the back of the LED display screen 6, a heat sink 33 and a temperature sensor 35 are installed on the side of the heat sink 36 away from the LED display screen 6, side ventilation holes 34 are opened on the left and right sides of the protective frame 32, and bottom ventilation holes 37 are opened at the bottom of the protective frame 32.

[0022] To be more specific, the main frame 3 is provided with a camera 2 for acquiring images and a speaker 5 for playing sound sources.

[0023] More specifically, a top rain shield 7 is installed above the main frame 3 where the camera 2 is installed. The top rain shield 7 can block a certain amount of rainwater to prevent the rainwater from entering the camera 2, causing the camera 2 to malfunction and be damaged.

[0024] More specifically, the temperature sensor 35 is electrically connected to the air supply fan 31, and the air supply fan 31 is electrically connected to the solar panel 1. The solar panel 1 is used to power the air supply fan 31, and when the temperature inside the main frame 3 is too high, the temperature sensor 35 will sense it and start the air supply fan 31 to dissipate heat and cool down the LED display 6 and the heat sink 36.

[0025] More specifically, a plurality of heat dissipation columns 33 are provided and are distributed on the heat dissipation plate 36. The heat dissipation columns 33 can enhance the heat dissipation capacity of the heat dissipation plate 36.

[0026] More specifically, the side vents 34 are provided with isolation screens 38 that can isolate insects and dust.

[0027] More specifically, the contact surface of the heat sink 36 is larger than the contact surface of the LED display screen 6. The heat sink 36 can better dissipate heat for the LED display screen 6, thereby ensuring the heat dissipation capacity of the LED display screen 6.

[0028] More specifically, at least one temperature sensor 35 is provided, and all are distributed on the back of the heat sink 36. Multiple temperature sensors 35 can better monitor the surface temperature of the heat sink 36 and better ensure the heat dissipation and cooling capability of the LED display screen 6.

[0029] The working principle of the utility model is as follows: when using the utility model, the staff should first install the device to the designated position, and the solar panel 1 can convert its light source into electricity and supply power to the device, and the LED display screen 6 can display and exhibit relevant information. When in use, when there is air flow from the outside, the flowing air will enter the inside of the main frame 3 through the side vents 34 on both sides, and take away the heat on the heat sink 36 and the heat sink 33, thereby ensuring the cooling and heat dissipation effect of the LED display screen 6. When there is no air flow from the outside and the temperature inside the main frame 3 is too high, the temperature sensor 35 will sense it and start the air supply fan 31, and the air supply fan 31 will cool it down. Among them, the camera 2 can obtain images to increase the practicality of the device, and the speaker 5 can play the sound source.

[0030] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
