[0002] Photovoltaic power generation is a pollution-free, renewable, and widely distributed clean energy source, and a leading energy source for promoting the implementation of "dual-carbon" goals. Photovoltaic energy storage devices collect solar energy through photovoltaic panels and convert it into electrical energy, storing it in battery packs for use on cloudy days, at night, and in areas with limited power supply. With continuous societal progress and the increasing demand for clean energy, traditional mobile power sources, such as fuel generators and small mobile energy storage batteries, while still holding a place, are increasingly showing their limitations. At the same time, photovoltaic power generation technology is no longer limited to fixed installations or a single mode of powering only small devices, but is gradually evolving towards more flexible and portable photovoltaic energy storage devices. This development trend not only responds to the urgent global demand for energy conservation, emission reduction, and environmental protection, but also provides ample space and strong impetus for the innovation and application of photovoltaic energy storage technology.

Detailed Implementation

[0027] It should be noted that the terms "upper," "lower," "left," "right," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0028] The following is in conjunction with the appendix Figure 1-6The present invention is further described in detail as follows: A high-power mobile photovoltaic energy storage device adopts a modular design, which includes a photovoltaic acquisition module at the top, an energy storage module in the middle, and a traction module at the bottom; all components are connected by bolts to enhance the stability and reliability of the connection.

[0029] like Figure 1-4 As shown, the photovoltaic data acquisition module is located at the top of the assembly and consists of an inner frame 6, an outer frame 12, photovoltaic panels 11, a photovoltaic support 10, a guide rail 25, pulleys 26, and a winch 23. The inner frame 6 and the outer frame 12 are designed with a nested structure and can both work independently. The outer frame 12 is fixed to the carriage by fastening bolts. The inner frame 6 can slide along the length of the outer frame 12. A limiting part is set at one end of the inner frame 6. When the inner frame 6 is completely inside the outer frame 12, the limiting part is located outside the end of the outer frame 12 away from its sliding outlet. When both ends of the inner frame 6 slide out of the sliding outlet of the outer frame 12, the limiting part restricts the inner frame 6 from sliding further to prevent the inner frame 6 from detaching from the outer frame 12. That is, the size of the limiting part is larger than the inner diameter of the sliding outlet of the outer frame 12. There are multiple photovoltaic panels 11, which are installed in the inner frame 6 and the outer frame 12 respectively. The bottom of the outer frame 12 is installed on the energy storage module.

[0030] like Figure 2-4 As shown, two rows of sliders 14 are arranged parallel to each other at the lower end of the outer frame 12. The sliders 14 move along the guide rail 25 set at the bottom of the inner frame 6. The guide rail 25 and the sliders 14 form a slide rail mechanism. A lifting ring 24 is installed at the tail of the inner frame 6. The wire rope on the winch 23 is connected to the lifting ring 24 along the pulley 26 installed from the lower end of the outer frame 12. Because the photovoltaic panel 11 is not in a horizontal state, and under the combined action of the active traction force provided by the winch 23 and the weight of the photovoltaic panel 11, the slide rail mechanism realizes a smooth and controllable linear extension and retraction movement of the photovoltaic panel. Using this mechanical limiting method, it is ensured that the inner frame 6 can be braked when it moves to the designated position to prevent damage to the equipment due to overtravel. At the same time, the top limiting part (outer extension frame) of the inner frame 6 can serve as a support structure. After the inner frame 6 is fully extended, it works in conjunction with the continuous pulling force provided by the winch 23 to jointly form the key support force for the unfolding of the inner frame 6. At this point, the tension of the wire rope and the rigid support of the outer structure combine to form a stable couple or lever support system, effectively resisting the overturning moment of the inner frame 6 and photovoltaic panel 11 due to their own weight, wind load, etc., ensuring the overall rigidity and stability of the deployed state. Driven by the winch 23, it extends outward to expand the working area and complete its expansion function.

[0031] As a preferred embodiment of this example, Figure 3-6As shown, the photovoltaic acquisition module also includes a baffle 8 and a slide rail 7. The baffle 8 is installed at both ends of the inner frame 6 and the outer frame 12 along their length, and its length direction is consistent with the width direction of the inner frame 6 and the outer frame 12. The slide rail 7 is set at one end of the photovoltaic bracket 10 and can slide along the length direction of the baffle 8. The other end of the photovoltaic bracket 10 is a free end. Both ends of the photovoltaic panel 11 are installed inside the photovoltaic bracket 10. Each photovoltaic panel 11 is independently distributed in each layer, and slide rail 7 is installed at both ends, so that it can work independently in the working layer.

[0032] As a preferred embodiment of this example, Figure 1 As shown, the photovoltaic data acquisition module also includes a locking mechanism, which mainly consists of a latch 15 and a plunger 13. The latch 15 is installed at a specific position at the connection between the inner frame 6 and the outer frame 12. Its main function is to mechanically lock the inner frame after the photovoltaic panel is fully retracted, preventing it from sliding down due to gravity or accidental vibration. The plunger 13 is installed in the limiting holes opened at corresponding positions on the inner frame 6, outer frame 12, baffle 8, and slide rail 7, thereby limiting the photovoltaic panel 11 within the inner frame 6 and outer frame 12 respectively. This component works in conjunction with the self-locking device integrated into the slide rail 7. Its core function is to engage in real-time or in stages during the system's retraction process, effectively resisting the forces that may cause the photovoltaic support 10 to unfold unexpectedly due to motion inertia or slope gravity, ensuring a smooth and controllable retraction process, and providing temporary locking in the middle position to prevent the photovoltaic panel 11 from moving along the slide rail 7 when retracted.

[0033] The energy storage module includes a carriage 9, which houses a photovoltaic energy storage battery and a photovoltaic-energy storage integrated unit 22. One end of the integrated unit 22 is connected to the photovoltaic data acquisition module, and the other end is connected to the photovoltaic energy storage battery. The integrated unit 22 is connected to a distribution box, which in turn connects to the vehicle's electrical circuitry. Specifically, the middle layer consists of battery modules and a power management module. The entire module includes a battery 20, a high-voltage electrical box 21, an inverter, and various switches and interfaces. Photovoltaic panels 11 collect solar energy, which is transmitted via cables to the inverter for energy conversion and then stored in the battery 20, achieving photovoltaic-energy storage integration. The electronic equipment of the power management module is installed in the middle carriage, while the inverter and electrical control box are installed on both sides of the carriage, equipped with observation windows and operating doors. The battery 20 and high-voltage boxes are installed and secured in the middle of the carriage. Cooling fans are installed at the front and rear ends of the carriage to facilitate ventilation and heat dissipation of the electronic components. Mains charging and output interfaces are also provided on both sides of the carriage, and a communication interface is designed at the front, allowing the tractor to control the taillights to alert following vehicles.

[0034] Specifically, carriage 9 also includes an electrical box 4, taillights 16, a fan 7, a battery 20, a high-voltage electrical box 21, and a photovoltaic-energy storage unit 22. The electrical box 4 and the photovoltaic-energy storage unit 22 are installed on both sides of carriage 9. The electrical box 4 contains switches, indicators, and other equipment to control the start and stop of the equipment. The battery 20 and the high-voltage electrical box 21 are installed in the middle of carriage 9 to store the electrical energy generated by the photovoltaic panels 11.

[0035] As a preferred embodiment of this invention, in order to prevent the temperature inside the compartment 9 from getting too high during operation, a temperature sensor is installed inside the box. The photovoltaic storage unit and battery pack will release a lot of heat energy when they are working. If the temperature is too high, it will affect the stable operation of the equipment. When the thermocouple temperature sensor detects that the temperature inside the box exceeds the preset temperature, the fans on both sides of the box will start. The real-time temperature inside the compartment 9 can be displayed on the temperature controller to observe the temperature status inside the box.

[0036] The side of carriage 9 is equipped with power interface 5, which can be used according to the site conditions. It has three output terminals, including one single-phase output and two three-phase outputs, and one mains power input terminal.

[0037] The traction module is based on a flatbed trailer, with a traction ball joint 2 installed at the front and support columns 19 on both sides. The entire device can be lifted by a rocker arm. The trailer tires are front wheels 1, tubeless tires 18, and equipped with shock-absorbing steel plates.

[0038] After the traction equipment transports the device to the designated position, release the traction ball joint 2 and lower the uprights 19 on both sides of the chassis 3 to raise the entire vehicle body to ensure that the vehicle body remains level.

[0039] like Figure 4-6 As shown, after the entire equipment is transported to the appropriate location, the column 19 is raised, the equipment is placed stably, the battery 20, the high-voltage electrical box 21, and the photovoltaic-storage integrated unit 22 are started, and the power supply is turned on to power the winch 23. The latch 15 is opened, and the inner frame 6 separates along the guide rail 25 under the combined action of gravity and the winch 23, stopping its movement after reaching the preset position. The plunger 13 is opened, and the photovoltaic panel 11 can unfold to both ends along the slide rail 7.

[0040] The above embodiments are merely preferred embodiments of this utility model and do not constitute a limitation thereof. The photovoltaic panels are not limited to the four panels in this embodiment and can be adjusted as needed. Any extensions, modifications, etc., made by those skilled in the art without departing from the principles of this utility model should be included within the protection scope of this utility model.
