Problems solved by technology

[0003] In daily life, billboards can be seen everywhere, and there are many types, but most of the existing billboards need to be connected to the mains when they are illuminated and displayed, which consumes a lot of energy
Although some billboards use solar energy for power supply, many of them are just forms. The conversion efficiency of their solar energy collection devices is not high, and a large amount of electricity is still needed; even if some billboards have solar energy collection devices that can improve conversion efficiency to a certain extent, But in fact, the conversion efficiency is still not ideal, and the structure of the solar energy concentration device is complicated and expensive, so it is not suitable for large-scale promotion and use.

Embodiment 1

[0042] Such as figure 1 As shown, it is a functional block diagram of a solar billboard provided in this embodiment. The solar billboard includes a main body, a controller, a display screen, an electric energy storage device and an automatic adjustment solar energy collection system. The controller is connected with the display screen to control The device and the electric energy storage device are placed in the main body, the display screen and the automatic adjustment solar energy collection system are placed on the main body, and the automatic adjustment solar energy collection system is respectively connected with the controller and the electric energy storage device through the control circuit. Such as Figure 12 As shown, it is a structural schematic diagram of a solar billboard in this embodiment. The display screen 102 is arranged on the outer wall of the main body 101 for displaying advertisement pictures, and the automatic adjustment solar energy collection system 10...

Embodiment 2

[0046] Such as image 3 As shown, it is a schematic structural diagram of the guiding device of this embodiment. The guiding device 2 includes a refractive layer 21 , a heat absorbing layer 22 , a thermodeformable layer 23 , a piezoelectric layer 24 and an electrode layer 25 from top to bottom. Among them, the refraction layer 21 is provided with several light-guiding surfaces 211, each light-guiding surface 211 has a different angle with the horizontal plane, and different light-guiding surfaces correspond to different sun positions. , sunlight can enter the refraction layer 21. If the sunlight does not directly strike the light-introducing surface 211, the sunlight will obliquely enter the other light-introducing surface 211 and be refracted away, and cannot fall on the heat absorbing layer. Preferably, the heat absorbing layer 22 is made of graphite or graphene with good thermal conductivity, which can effectively absorb the heat of the sun and transmit it to the thermodef...

Embodiment 3

[0051] Such as Figure 4 Shown is a schematic structural view of the guiding device of this embodiment. The difference between this embodiment and the above-mentioned embodiments is that a gap 212 is provided between adjacent light-introducing surfaces on the refraction layer in this embodiment. Since sunlight needs to be directly irradiated to enter the refraction layer, the setting of the gap 212 prevents sunlight from entering the refraction layer all the time, that is, the guiding device 2 will not send information on the position of the deformation to the processor 3 every moment, and then the processor 3 It is not necessary to control the driving motor 52 all the time to adjust the angle between the solar tube 1 and the incident light of the sun to keep it vertical.

[0052] Due to the setting of the gap 212, the processor 3 will control the drive motor 52 to adjust the solar tube 1 at intervals, thereby reducing the working time of the drive motor 52 and providing energ...

Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to a solar billboard. Background technique [0002] Now, people are more and more aware of the important value of solar energy, especially in the current situation that countries around the world are facing increasing energy shortages. People have regarded solar energy as one of the main modern new energy sources for development and utilization. With the continuous development of science and technology, People are also increasingly extensive and in-depth to the utilization of solar energy. [0003] In daily life, billboards can be seen everywhere, and there are many types, but most of the existing billboards need to be connected to the mains when they are illuminated and displayed, which consumes a lot of energy. Although some billboards use solar energy for power supply, many of them are just forms. The conversion efficiency of their solar energy collection devic...
