Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage technology, specifically to a photovoltaic folding and retracting device for a hybrid energy storage power station. Background Technology

[0002] Hybrid energy storage power stations are a new type of energy storage model developed to address the limitations of single energy storage technologies. By integrating energy storage technologies with different characteristics (such as electrochemical, mechanical, and electromagnetic energy storage), they achieve complementary advantages to meet the diverse needs of the power system. With the increasing penetration of fluctuating renewable energy sources such as wind and solar power, the power grid places higher demands on the power response speed, energy duration, and economic efficiency of energy storage systems. Single energy storage technologies struggle to achieve all these goals; for example, lithium batteries have high energy density but slow power response, supercapacitors have fast response but limited capacity, and flow batteries have long cycle life but low energy density. Hybrid energy storage, through optimized configurations (such as combinations of lithium iron phosphate + supercapacitors, or vanadium redox flow batteries + lithium batteries), can simultaneously achieve millisecond-level frequency regulation, hourly peak shaving, and ultra-long-duration energy storage, improving system stability and economic efficiency. At the policy level, the Ministry of Industry and Information Technology and other departments encourage the exploration of various types of hybrid energy storage technologies, promoting their large-scale application on the grid side, user side, and in new energy supporting scenarios, making them a key support for the new power system.

[0003] Currently, most photovoltaic panels in hybrid energy power stations and lighthouses, both domestically and internationally, are fixed to the ground and are not easy to move. In the actual process of collecting solar energy, the photovoltaic panels may need to be moved according to power supply needs. Therefore, there is a need to provide a photovoltaic folding and retraction device for hybrid energy storage power stations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a photovoltaic folding and retraction device for hybrid energy storage power stations, so as to solve the technical problem that the photovoltaic panels of most hybrid energy power stations and lighthouses at home and abroad are fixed on the ground and are not easy to move. In the actual process of collecting light energy, the photovoltaic panels may need to be moved according to the power supply demand.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A photovoltaic folding and unfolding device for a hybrid energy storage power station includes a trailer. The trailer has wheels at its bottom and guide wheels at its front end. A control cabinet is fixedly installed on the top of the trailer. An inclined bracket is fixed on the top of the control cabinet. A photovoltaic panel unfolding and unfolding device is fixed on the top of the bracket. A photovoltaic panel is installed on the top of the photovoltaic panel unfolding and unfolding device.

Example

[0023] Please see Figure 1-6 The present invention provides a technical solution: a photovoltaic folding and unfolding device for a hybrid energy storage power station, comprising a trailer 3, a traveling wheel at the bottom of the trailer 3, a guide wheel 1 at the front end of the trailer 3, a control cabinet 2 fixedly installed at the top of the trailer 3, an inclined bracket 8 fixedly installed at the top of the control cabinet 2, a photovoltaic panel unfolding and unfolding device 7 fixedly installed at the top of the bracket 8, and a photovoltaic panel 5 installed at the top of the photovoltaic panel unfolding and unfolding device 7.

[0024] The trailer 3 has four outriggers 13 along its edge, and these outriggers 13 are retractable. Specifically, in this embodiment, the present invention includes a trailer at the bottom of the photovoltaic panel deployment and retraction device. The trailer is equipped with wheels at its bottom for easy movement and transfer of the device. Guide wheels are located at the front of the trailer for easy directional control during movement. Four support legs are provided along the edge of the trailer to improve stability when parked. A control cabinet is fixedly mounted on the top of the trailer, and an inclined bracket is fixed to the top of the control cabinet to facilitate tilting and fixing the photovoltaic panels, thereby improving the light energy absorption of the panels.

[0025] Example 2 Please see Figure 1-6 This is another technical solution provided by the present invention. This embodiment has the same features as the above embodiment 1, and the similarities will not be described in this embodiment. The specific differences are as follows: The photovoltaic panel receiving and discharging device 7 has symmetrical photovoltaic panel receiving slots 14 on its left and right sides, and a side photovoltaic panel 15 is slidably connected in the photovoltaic panel receiving slot 14 on each side.

[0026] Each side of the photovoltaic panel recovery groove 14 is provided with a self-locking guide rail 4 on its upper and lower walls. The upper and lower ends of the side photovoltaic panel 15 in the photovoltaic panel recovery groove 14 are slidably connected to the self-locking guide rail 4.

[0027] The photovoltaic panel 5 and the side photovoltaic panels 15 on both sides are connected to the control cabinet 2 by three photovoltaic panel connecting cables 9.

[0028] The photovoltaic panel take-up and take-down device 7 has reciprocating sliding pins 6 symmetrically arranged on the left and right sides. Each photovoltaic panel 5 has an ear plate 16 on its surface, and the ear plate 16 has a pin hole that matches the pin 6.

[0029] The purpose of this utility model is to design a photovoltaic folding device, which is small in size, easy to operate, has neat wiring, beautiful appearance, and strong adaptability, providing customers with an energy-saving and safe power supply environment.

[0030] Specifically, in this embodiment, the present invention significantly reduces the volume of the three photovoltaic panels after folding through a compact structural design. Specifically, in this embodiment, the present invention hides the photovoltaic panel's cables inside by controlling the gaps to a smaller size, thereby improving the overall aesthetics and rainproof performance. Specifically, in this embodiment, the present invention uses a redundant limiting design after the photovoltaic panel is retracted. The guide rail itself has a self-locking mechanism, and an additional set of pins is installed to avoid the risk caused by the failure of the guide rail self-locking mechanism. Specifically, in this embodiment, the present invention uses a modular design to facilitate the assembly of the photovoltaic receiving and discharging device. After assembly, the entire device can be lifted onto the hybrid power supply equipment.

Four LED lights 10 are fixedly installed on the top of the lifting rod 11 to provide ambient lighting for the photovoltaic panel 5 during operation. For convenient construction, a winch 12 is fixedly installed at the bottom of the lifting rod 11. The winch 12 winds up the cable that powers the LED lights 10, making it easy to control the cable length during the extension and retraction of the lifting rod 11 and preventing excess cable from getting tangled on the surface of the lifting rod 11, which would affect the safety of the cable.
