Description

Technical Field

[0001] The present application relates to the field of street lamps, and in particular to a deployable high-efficiency power generation solar street lamp. Background Art

[0002] Solar street lights are a common type of street light currently available. Their main advantage is that they can achieve self-energy storage through sunlight, thereby realizing the integration of power generation, energy storage, and power supply. Their main technical point is to improve the power generation efficiency, so that the energy supply time can be long enough. However, improving the power generation efficiency of solar panels per unit area requires gradual technological progress and iteration.

[0052] As shown in the figure, the solar street light of the present application has a lighting unit that is fixedly connected to the lamp pole through a connecting unit, so that the connection is convenient. When installing on site, it is only necessary to connect the lighting unit to the lamp pole unit through the connecting unit. The lighting unit has three LED lamp heads, so that farther lighting and a larger range of lighting can be achieved. In addition, the battery and the control unit can be installed in the storage box, so that the structure is more compact. A temperature sensor is installed in the storage box, so that the cooling fan can be started to dissipate heat when the temperature is too high.

[0053] In any case, the fixed solar panels on the top can be used to generate electricity, always maintaining a certain power generation efficiency. In good weather, the first and second solar panels on both sides can be unfolded for power generation, and in bad weather, the first and second solar panels can be stored in the storage box, so that the lighting unit will not be damaged in strong winds. The specific steps of unfolding and storing are as follows: Figure 1 This is a schematic diagram in the storage state. At this time, the first and second solar panels are both stored in the storage box, and the first limit abutment plate abuts the outer side of the first end plate, and the second limit abutment plate abuts the outer side of the second end plate, thereby protecting the first and second solar panels. The first and second limit abutment plates can prevent the drive motor from overdriving and limit the position, thereby protecting the entire lighting unit. Next, the drive motor drives the transmission belt to move, and the movement distance of the first movable block and the second movable block is always kept equal. With the transmission of the synchronous belt, it will first change to Figure 2 In the first transition state shown, the first and second solar cell panels are partially extended out of the container; then the transmission continues, as shown in FIG. Figure 5 As shown, the first solar panel is completely extended out of the storage box, the second solar panel is mostly extended out of the storage box, and the second slide bar and the second solar panel have been relatively displaced; then continue to rotate, as shown in FIG. Figure 6 As shown, the limiting pin of the first solar cell panel enters the second limiting groove; then the transmission continues, as shown in FIG. Figure 7 As shown, the position of the first solar cell panel is relative to Figure 6 The first solar panel remains unchanged, but the position of the movable panel moves toward the inside of the storage box, and the second solar panel continues to extend out of the storage box. Thus, the first solar panel is fully unfolded, and although only a small part of the first and second solar panels are located in the storage box, most of them extend out of the storage box. However, since the first solar panel is supported by the movable box and the second solar panel is supported by two slide rod units, a large part of the movable panel and the two slide rod units are located in the storage box. Therefore, the support for the first and second solar panels is very stable as a whole, which not only obtains a larger power generation area of ​​the solar panel, but also obtains a higher stability of the solar panel after unfolding. When it is necessary to switch to the storage state, just reverse the above process.

[0054] 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.
