Reel 121 is used for winding flexible solar panel 130, and electric motor drives reel 121 to realize the unfolding and retraction of solar panel. Flexible solar panel 130 is made of flexible photovoltaic material that can be curled, usually is made of flexible material base (such as polyimide film, PET film, EVA film) on which photovoltaic unit (battery piece) is coated or embedded, common material is: flexible monocrystalline silicon wafer, flexible copper indium gallium selenium (CIGS) film, flexible organic photovoltaic material (OPV) etc., and flexible solar panel 130 can be curled, bent, even twist to a certain extent without damaging. Flexible solar panel 130 one end is fixed on reel 121, and the other end can be connected between the two guide rails of electrically reversible guide rail 140 through sliding. Flexible solar panel 130 can be stretched from the storage bin 120 to the outside of the shell under the guidance of the two guide rails, and is unfolded to form a substantially flat surface to absorb solar energy. In order to ensure that the flexible solar panel 130 can be smoothly slid out and unfolded, a self-adaptive guide mechanism needs to be set up to solve the problem of different angle docking, including elastic transition structure in the prior art, specifically, a flexible guide plate or an elastic pressing strip is arranged between the outlet of the storage bin 120 and the electrically reversible guide rail 140, the flexible guide plate can naturally bend and dock with the guide rail angle changes slightly, and play the role of "guiding sliding". When the solar panel is extended, no matter how much the guide rail angle changes, the flexible plate can guide the panel into the guide rail track. In addition, universal hinge or other solutions can also be considered, as prior art, no more description is made.

[0024] Further, the electrically reversible guide rail 140 is arranged on the rear side or top of the main body casing 100, including two parallel guide rails and a reversible hinge. One end of the guide rail is connected to the outlet of the storage bin 120, and the other end is connected to the reversible hinge. The reversible hinge can be reversed under the action of the stepping motor connected thereto. The wind speed sensor 150 is installed on the outside of the main body casing 100 or the lamp pole 200, and monitors the environmental wind speed data in real time. The control module is arranged in the main body casing 1, and is electrically connected with all electrical elements such as the stepping motor and the wind speed sensor 150. The control module can determine the wind force according to the detection result of the wind speed sensor 150, and issue instructions to control the winding of the flexible solar panel 130 and the reversal of the electrically reversible guide rail 140.

[0025] Further, the storage bin 120 is internally provided with a winding mechanism, which includes a winding shaft 121 and an electric motor. The storage bin 120 is a hollow cavity, which is internally provided with a space for mounting the winding mechanism. The winding shaft 121 is transversely arranged and penetrates the inside of the storage bin 120. The winding shaft 121 is a solid cylinder made of lightweight aluminum alloy. Bearings are generally arranged at both ends of the winding shaft 121 to ensure stable rotation of the winding shaft. The electric motor is a small DC motor, which is connected with the winding shaft 121 through a shaft coupling or a synchronous pulley. The electric motor is driven by the control module and can control the winding shaft 121 to wind or release the flexible solar panel 130 in forward rotation or reverse rotation. One end of the flexible solar panel 130 is fixed on the surface of the winding shaft 121 through bonding, riveting or mechanical clamping structure. It is ensured that the flexible solar panel 130 can be naturally wound or released along with the rotation of the winding shaft 121.

[0026] Further, the electrically reversible guide rail 140 is connected with the main body shell 100 through a reversible hinge. The reversible action is realized by a step motor. The reversible hinge includes a fixed end and a rotating end. The reversible hinge is located at the rear side of the main body shell 100. The step motor is directly driven. The output shaft of the step motor is directly connected with the rotating shaft of the reversible hinge to realize the rotation output and the reversible action of the electrically reversible guide rail 140. In other embodiments, a gear drive or a connecting rod drive can be adopted. The electrically reversible guide rail 140 can be adjusted according to the sunlight angle. The control module is provided with a sunlight angle detection function. A small light sensor array (such as a four-quadrant photosensitive sensor or a multi-point light intensity detector) is generally arranged on the lamp head. The array can detect the light intensity in different directions. The main incident direction of the sunlight is calculated by comparing the light intensity data in different directions (such as front, back, left and right). The control module determines the position of the sun in the sky according to the calculated direction, so as to determine the angle of the guide rail which needs to be adjusted to optimally receive light. The control module is provided with a wireless communication module. The working state of the flexible solar panel 130 and the wind speed information can be transmitted to a remote server or a terminal device in real time. The control module is provided with an MCU main control chip and integrates data collection of various sensors, such as solar panel output detection and wind speed sensor data. The wireless communication module includes a WiF module and a 4G / 5G cellular module. The packaged data is uploaded to a remote cloud server or sent to a user mobile phone App or a PC terminal platform through the wireless communication module. The lamp head can be remotely and real-timely monitored, so that the management personnel can see the unfolding and folding state of the solar panel, the wind condition and whether the solar panel is faulty of each set of street lamp in the background at any time without on-site inspection. Or, the solar panel folding action is automatically triggered according to the real-time wind speed to improve the safety and avoid damage caused by strong wind. The guide rail angle can also be remotely adjusted according to the sunlight intensity to improve the power generation efficiency.

[0027] Further, the storage bin 120 is provided with a sealing cover at the opening, which can be closed to prevent dust and rain from entering the storage bin 120 when the flexible solar panel 130 is retracted. The sealing cover is a flexible or hard plate material (such as a rubber cover, a plastic cover or a thin metal plate) installed at the edge of the opening of the storage bin 120, which is usually elastic. The size of the sealing cover is slightly larger than the opening of the storage bin, which can cover the entire opening, and is provided with a sealing ring (waterproof rubber strip) around the opening to prevent dust and water. Generally, the sealing cover is also provided with a spring return structure to achieve automatic closing. Specifically, the sealing cover is connected to one side of the storage bin 120 through a hinge. A torsional spring is arranged in the hinge position. When the flexible solar panel 130 is unfolded, the solar panel body or the guide rail mechanism pushes the sealing cover to open it. When the solar panel is retracted, the pressure is released, and the torsional spring naturally returns to the original position, and the sealing cover is popped back and pressed against the opening. In this way, the sealing cover will automatically close and press the storage bin.

[0028] Further, a street lamp comprising the street lamp head described above further comprises a lamp pole 200 and a foundation installation component connected with the street lamp head, the lamp pole 200 is used for supporting the street lamp head and providing a power line connection channel, and the top of the lamp pole 200 is provided with a mounting seat or a flange plate matched with the bottom of the street lamp head to realize stable connection. The foundation installation component usually comprises an anchor bolt, a grounding device and a concrete foundation.

[0029] In the utility model, the working process of the street lamp head is as follows:

[0030] When the street lamp is in normal working state and the environmental wind speed is lower than the preset safety threshold, the control module sends out an instruction to control the electric motor to drive the reel 121 to rotate in the positive direction, so as to slowly unfold the flexible solar panel 130 in the storage bin 120 through the guide rail of the electrically reversible guide rail 140. In the unfolding process, the flexible solar panel 130 is transitioned through the flexible guide plate or elastic pressing strip arranged at the opening of the storage bin 120 and smoothly slides into the track of the electrically reversible guide rail 140, and finally is unfolded into a plane approximately horizontal or inclined to maximize the absorption of solar light and perform photovoltaic power generation. After the solar panel 130 is completely unfolded, the electric motor stops rotating, and the solar panel remains in the unfolded state. The control module can determine the current sunlight incidence direction according to the built-in sunlight angle detection function and drive the stepping motor to adjust the angle of the electrically reversible guide rail 140 to optimize the light receiving area of the flexible solar panel 130 and thus improve the power generation efficiency. At the same time, the wind speed sensor 150 monitors the environmental wind speed data in real time and transmits the data to the control module. When it is detected that the environmental wind speed exceeds the preset threshold (such as 10 m / s or more), the control module automatically starts the retraction program and sends out an instruction that the electric motor reverses to drive the reel 121 to rotate, slowly winding the flexible solar panel 130 into the storage bin 120; during the winding of the solar panel 130, the guide rail continues to guide the solar panel to smoothly slide into the storage bin 120; when the flexible solar panel 130 is completely stored in the bin, the sealing cover at the opening of the storage bin 120 is automatically closed under the action of the torsional spring and tightly seals the sealing ring to prevent rainwater and dust from entering the inside of the storage bin; at the same time, the stepping motor continues to act to drive the electrically reversible guide rail 140 to be reversed to the top or side of the main body shell 100 to reduce the wind area of the street lamp as a whole, improve the wind resistance, and avoid damage or falling of the solar panel due to strong wind.
