Description

Technical Field

[0001] The present invention relates to the technical field of containerized solar panels, and in particular to automatic extending equipment for containerized solar panels. Background Art

[0002] Solar energy is a renewable energy source. It refers to the thermal radiation energy of the sun, which is mainly manifested in the so-called sunlight. In modern times, it is generally used to generate electricity or provide energy for water heaters.

[0003] Since the birth of life on Earth, it has mainly survived on the heat radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and as a method of making food, such as making salt and drying salted fish. With the decreasing fossil fuels, solar energy has become an important part of human energy and is constantly developing. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy is the main source of global electricity growth and a highlight of renewable energy development.

[0004] In related technologies, solar panels are often used to realize the photoelectric reaction of solar energy. Since the efficiency of solar panels in converting electrical energy is not high, a certain sunlight collection area must be achieved when they are used, that is, solar panels need to be laid over a large area.

[0005] When the solar panels need to be moved, multiple solar panels need to be stacked and stored in a box, such as a container, for transportation. After the transportation location is transferred, the stacked solar panels are unfolded to generate solar power.

[0006] Folding solar panels are manually operated during storage and deployment, and there is no fully automated operation equipment with integrated power. Related technologies include bottom rope dragging, but after folding, manual fixation and positioning are required, and mutual pulling positioning is performed on the sides to prevent shaking; it also includes power transmission through chains or other structures, such as rope structures or train track structures, or gear rack structures to achieve solar panel storage and deployment operations, all of which require manual operation.

[0007] Due to the weight and size of solar panels, it is inconvenient to store and unfold the solar panels, and the efficiency of manual storage and unfolding of solar panels is relatively low.

[0008] Application number: 202110009476.1, patent name: An energy-saving photovoltaic solar device that can be automatically stored and unfolded, discloses an energy-saving photovoltaic solar device that can be automatically stored and unfolded, including a box body, a gear ring cavity is arranged in the box body, a central axis is fixedly arranged between the upper and lower end walls of the gear ring cavity, and three storage and unfolding mechanisms for photovoltaic solar panels that rotate corresponding angles to fully spread are evenly arranged at the gear ring cavity. The storage and unfolding mechanism includes three positioning annular blocks evenly fixed on the central axis, and the central axis is evenly rotated and connected with three gear rings, and the inner ring wall of the gear ring is fixedly provided with a positioning annular groove opening to the central axis. The right side of the gear ring is provided with a turning mechanism that uses tooth segments of different lengths to control the rotation angle of each photovoltaic panel. The present invention uses a simple rotation and pneumatic lifting mechanism to realize the automatic storage and unfolding of solar arc photovoltaic panels, and ensures that only the photovoltaic solar panel device in use is powered. The above invention has a simple structure and is not suitable for the storage and unfolding of multiple folding solar panels.

[0009] Therefore, there is a need for a containerized solar panel automatic extension device to realize the fully automated operation of folding solar panels for storage and unfolding, replace manpower, and improve the efficiency and safety of solar panel operation. Summary of the invention

[0057] The auxiliary power motor 61 is connected to the stirring rod 63 through the power transmission component 62. The stirring rod 63 can be lifted up or lowered under the action of power. A telescopic rod 64 is provided at the end of the stirring rod 63. The telescopic rod 64 is connected to the telescopic motor through a screw and can reciprocate and telescopic along the stirring rod 63. A gripper 65 is provided on the top of the telescopic rod 64.
