[0002] In order to further respond to environmental protection policies, photovoltaic power generation is constantly being used. Photovoltaic power generation is mainly achieved through photovoltaic panels. Photovoltaic panels convert light energy into electrical energy under photosynthesis, and store the electrical energy in batteries connected to the photovoltaic panels to facilitate the conversion and utilization of light energy.

[0003] The storage space and service life of the batteries equipped on the solar photovoltaic panels are limited, so the batteries on the photovoltaic panels need to be replaced regularly. Some batteries are fixedly connected to the brackets on the solar photovoltaic panels, which makes it inconvenient to replace the batteries later. The installation of other battery groups requires the use of specially designed battery cabinets. Battery cabinets usually have protection and heat dissipation functions, which can provide a safer and more stable environment. However, due to the limitations of the internal space of the energy storage cabinet, when the operator takes the battery, the operator's hands will be blocked by the energy storage cabinet, making it impossible to hold the battery stably, and it is also inconvenient to repair the cables later.

[0004] Finally, the existing solar power generation devices are generally placed outdoors for use, directly contacting the outside to absorb energy from the sun. When encountering adverse conditions, such as strong winds and sand, the solar power generation devices will be damaged. Therefore, a solar photovoltaic panel replacement battery is proposed to solve the above problems.

Multiple battery bodies 8 are connected in parallel inside the energy storage box 1 to convert and utilize light energy.

[0036] The rotating frame 5 includes a gear 51, and two rotating shafts 52 are provided at the upper end of the gear 51. A connecting column 54 fixed to the gear 51 is installed in the middle of the two rotating shafts 52.

The applicable temperature of the battery core 84 is -40°C to +70°C. A battery slot 74 is provided in the middle of the mounting frame 71. After the battery body 8 is installed inside the battery slot 74, the cover plate 82 slides into the slide groove 76 and upwardly connects to the conductive sheet 77 through the electrical connection plate 83. The cover plate 82 squeezes downward to fix the battery core 84, so that the battery core 84 is stably mounted in the battery holder 7. The conductive connection is quickly made while being installed through the battery holder 7, which facilitates the subsequent replacement and maintenance of the battery body 8.

[0039] Specifically, when the solar photovoltaic panel replacement battery is in use: the heat exchange box 13 is buried deep in the sand, and the sunshade of the photovoltaic panel 2 and the low temperature deep in the sand are used to cool the energy storage box 1, ensuring that the temperature of the energy storage box 1 and the battery body 8 is stable during energy storage and is not affected by the external temperature. The battery body 8 is pushed into the battery holder 7, and the battery body 8 is conveniently and quickly installed on the battery holder 7, and is conductively connected to the power rail 4. The first metal rail 41 and the second metal rail 42 are connected to the battery body 8 as the positive and negative poles respectively, and multiple battery bodies 8 are connected in parallel inside the energy storage box 1 to convert and utilize light energy. The electric energy (DC) generated by the battery assembly on the solar photovoltaic panel is transmitted to the battery body 8 through the control component inside the control box 3, and is stored in the battery body 8 for the subsequent load. The components used are convenient for converting and utilizing light energy. At the same time, the rotating frame 5 and the rotating mechanism 6 are driven by an external driving motor to rotate continuously at a uniform speed, and the position of the battery body 8 is replaced. The protective box 12 is installed under the photovoltaic panel 2. At the same time, the bottom of the gear 51 is equipped with fan blades 55 that penetrate into the heat exchange box 13. When the fan blades 55 rotate, the cold air inside the heat exchange box 13 is rolled up, and maintenance side doors are opened on both sides of the energy storage box 1. The rotating frame 5 is equipped with a support seat 9 and an electric push rod 10 pointing to the side door.
