[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a height adjustment mechanism, the remaining first straight gears are driven to respectively drive a first threaded screw to rotate, so that all the first threaded screws can rotate synchronously, thereby driving multiple sliding plates to move upward. Since the pitches of the multiple first threaded screws are arranged in order from small to large, multiple photovoltaic energy storage panels are moved upward in a stepped manner toward the sun, so that when the solar altitude angle is low in the morning, low-angle sunlight can be captured more effectively, thereby improving the utilization rate of light and thus improving the overall practicality of the device;

[0017] 2. By setting a rotation adjustment mechanism, the second threaded screw is driven to move downward, so that the protective shell rotates under the action of the rotating shaft, so that the photovoltaic energy storage panel can rotate synchronously with the change of time and the different angles of the sun, and can always maintain a nearly vertical position with the sunlight. When the sunlight shines on the head at noon, the photovoltaic energy storage panel returns to the initial position. At this time, the photovoltaic energy storage panel is in a horizontal position, and when the angle of the sun continues to change, the PLC controller controls the first drive motor to start, so that the photovoltaic energy storage panel can move downward, and when the sun is close to setting, the multiple photovoltaic energy storage panels are also stepped, so that the device can continuously change the angle and position of the photovoltaic energy storage panel with the change of sunlight, so as to ensure the maximum absorption of light, thereby improving the utilization rate of light and enhancing the overall practicality of the device;

[0018] 3. By setting a protection mechanism, the first threaded screw is driven to rotate, so that the photovoltaic energy storage panel is stepped, and then the photovoltaic energy storage panel moves downward, and the second spur gear is driven to rotate under the action of the spur rack, so that the protective shell can continue to rotate, so that the photovoltaic energy storage panel can rotate to a position parallel to the top surface of the protective panel, and when the photovoltaic energy storage panel can rotate to a position parallel to the top surface of the protective panel (the spur rack is separated from the second spur gear), the photovoltaic energy storage panel continues to move downward until the photovoltaic energy storage panel is attached to the top of the protective panel, thereby protecting the photovoltaic energy storage panel, thereby preventing rain and snow from soaking on the photovoltaic energy storage panel when it rains and snows, causing damage to the photovoltaic energy storage panel, and extending the service life of the photovoltaic energy storage panel. At the same time, it also prevents rainwater from entering the inner side of the protective shell along the photovoltaic energy storage panel, causing a short circuit in the wires inside the protective shell, thereby improving the stability of the device;

[0019] 4. By setting up photovoltaic energy storage panels, rainwater from the outside can flow out through the gaps between multiple photovoltaic energy storage panels, thereby preventing rainwater from accumulating on the top of the photovoltaic energy storage panels. At the same time, it can reduce the reflection caused by rainwater accumulation on the top of the photovoltaic energy storage panels, thereby improving the stability of the device and increasing the efficiency of the photovoltaic energy storage panels in absorbing light, thereby enhancing the overall practicality of the device;

[0020] 5. By setting up a storage mechanism, the sliding block is driven to move toward the side of the second rotating rod, thereby releasing the wires. When the protective shell moves downward, the second drive motor drives the sliding block to move in the opposite direction of the second rotating rod, thereby realizing the winding of the wires. In this way, the wires can always remain in an orderly and non-loose state when the protective shell moves, preventing the wires from being entangled with other components during the movement of the protective shell, thereby improving the protection of the wires and thus improving the stability of the device.

[0033] A light sensor is provided on the top of the protective shell 2. The light sensor can be a direction sensor. The sensor is composed of light-emitting diodes, photosensitive receiving transistors and other parts, and can sense the direction of light. The first drive motor 10 is controlled by a PLC controller, which can control the first drive motor 10 to start. When the sun just rises in the morning, the direction sensor senses that the light is shining from the east. At this time, the direction sensor will generate an electrical signal and transmit it to the PLC controller. The PLC controller controls the first drive motor 10 to start. The output end of the first drive motor 10 drives a first threaded screw 8 to rotate, thereby driving a first spur gear 11 to rotate, thereby driving the chain 12 to rotate, thereby driving the remaining first spur gears 11 to drive a first threaded screw 8 to rotate respectively, so that all the first threaded screws 8 can rotate synchronously, thereby driving multiple sliding plates 7 to move upward.

[0035] At the same time, when the sliding plate 7 moves upward, it can drive the connecting seat 15 to move upward, thereby driving the second spur gear 19 to move upward, so that the second spur gear 19 is driven to rotate under the action of the spur rack 18, thereby driving the worm 16 to rotate, thereby driving the worm wheel 17 to rotate, thereby driving the rotating shaft 14 to rotate, thereby driving the protective shell 2 to rotate, thereby driving the photovoltaic energy storage panel 3 to rotate, so that when the photovoltaic energy storage panel 3 moves upward, the photovoltaic energy storage panel 3 can rotate while moving, so that the angle between the photovoltaic energy storage panel 3 and the light is as vertical as possible, thereby increasing the light capture area, thereby improving the light absorption efficiency, and thus improving the energy utilization rate of the device;

[0036] When the sun rises, the direction sensor can continuously sense the direction of light as time changes, so as to transmit the information to the PLC controller. The PLC controller controls the first drive motor 10 to start, so as to drive the first threaded screw 8 to rotate, thereby driving the sliding plate 7 to move slowly downward, and driving the second threaded screw 25 to move downward, so that the protective shell 2 rotates under the action of the rotating shaft 14, so that the photovoltaic energy storage panel 3 can rotate synchronously with the change of time and the different angles of the sun, and can always maintain a nearly vertical position with the sunlight. When the sunlight shines on the top of the head at noon, the photovoltaic energy storage panel 3 returns to the initial position.
