Description

Technical Field

[0001] This utility model relates to a retractable photovoltaic power generation device, belonging to the field of photovoltaic power generation technology. Background Technology

[0002] A photovoltaic (PV) power generation device is a device that directly converts solar energy into electrical energy using the photovoltaic effect. The core principle of a PV power generation device is the photovoltaic effect, which utilizes the semiconductor material (such as silicon) within a solar cell to absorb photons from sunlight, exciting electrons to form electron-hole pairs. Under the influence of the electric field inside the solar cell, the electrons and holes are separated and flow in an external circuit to form an electric current, ultimately outputting electrical energy.

[0003] Existing photovoltaic (PV) panels are laid flat on PV racks to expose themselves to sunlight, directly converting solar energy into electricity and achieving rapid energy collection. However, PV panels occupy a significant amount of space when not in use and are not easily folded for storage. Furthermore, the relatively fixed location of the PV panels and racks limits their relocation, thus restricting their application scenarios.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a retractable photovoltaic power generation device that can be extended or folded for storage as needed and is easy to move, thereby expanding its application scenarios.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A retractable photovoltaic power generation device includes two symmetrically arranged first support bases, with multiple second support bases between the two first support bases. The first support bases and the second support bases, as well as adjacent second support bases, are connected by a flip frame and connecting rods. A photovoltaic panel is fixed to the side of the flip frame, and the photovoltaic panel and the flip frame are arranged in a one-to-one correspondence. The bottom of the first support base has two symmetrically arranged universal brake wheels, one of which is connected to the bottom of the first support base via a fixed support leg, and the other of which is connected to the bottom of the first support base via a telescopic support leg. The bottom of the second support base has two symmetrically arranged directional wheels, one of which is connected to the bottom of the first support base via a fixed support leg, and the other of which is connected to the bottom of the first support base via a telescopic support leg.

[0008] Furthermore, both the first support base and the second support base are U-shaped structures.

[0009] Furthermore, a flipping frame is installed inside the first support base, and the bottom end of the flipping frame is hinged to the first support base.

[0010] Furthermore, two flipping frames are installed inside the second support base, and the bottom end of the flipping frame is hinged to the second support base.

[0012] Furthermore, the outer side of the top of the tilting frame within the adjacent second support is connected by a connecting rod.

[0013] Furthermore, the flipping frame has a square structure, and the outer end face of the photovoltaic panel is flush with the outer end face of the flipping frame.

[0014] Furthermore, the first support base and the second support base, as well as adjacent second support bases, are connected by a latch, which is located on the outer side of the ends of the first support base and the second support base along the length direction.

[0015] Furthermore, multiple fixed support legs are located on the same side of the device, while multiple telescopic support legs are located on the other side of the device.

[0016] Furthermore, each of the two first support seats has a handle fixedly connected to its opposite outer side.

[0027] like Figures 1-4 As shown in the figure, this utility model provides a retractable photovoltaic power generation device, including two first support bases 1 symmetrically arranged, and a plurality of second support bases 2 provided between the two first support bases 1. The first support bases 1 and the second support bases 2, as well as adjacent second support bases 2, are connected by a flip frame 9 and a connecting rod 10.

[0028] Both the first support base 1 and the second support base 2 are U-shaped structures.

[0029] A flipping frame 9 is installed inside the first support base 1, and the bottom end of the flipping frame 9 is hinged to the first support base 1.

[0030] The second support base 2 has two flipping frames 9 installed inside, and the bottom end of the flipping frame 9 is hinged to the second support base 2.

[0031] The outer top of the inner flip frame 9 of the first support base 1 is connected to the outer top of the inner flip frame 9 of the second support base 2 via a connecting rod 10, and the two ends of the connecting rod 10 are hinged.

[0032] The top outer side of the flipping frame 9 in the adjacent second support 2 is connected by a connecting rod 10.

[0033] The flipping frame 9 has a square structure, and a photovoltaic panel 11 is fixed to the side of the flipping frame 9. The photovoltaic panel 11 and the flipping frame 9 are arranged in a one-to-one correspondence, and the outer end face of the photovoltaic panel 11 is flush with the outer end face of the flipping frame 9.

[0034] The first support base 1 and the second support base 2, as well as adjacent second support bases 2, are connected by latches 8. The latches 8 are located on the outer sides of the ends of the first support base 1 and the second support base 2 along the length direction. The latches 8 can fix the first support base 1 and the second support base 2 together, and fix adjacent second support bases 2 together.

[0035] The bottom of the first support base 1 has two symmetrically arranged universal brake wheels 3. One of the universal brake wheels 3 is connected to the bottom of the first support base 1 through a fixed support leg 5, and the other universal brake wheel 3 is connected to the bottom of the first support base 1 through a telescopic support leg 6.

[0036] The bottom of the second support base 2 has two symmetrically arranged directional wheels 4.

[0040] When this invention is extended, the latches 8 on both sides are first opened, and the handle 7 drives multiple flip frames 9 to extend in sequence. The photovoltaic panel 11 is laid flat after the flip frames 9 are extended. After the photovoltaic panel 11 is laid flat, the length of the telescopic support leg 6 can be adjusted to make the photovoltaic panel 11 tilted to maintain the best incident angle with the sunlight and ensure power generation efficiency. When this invention is folded, the handle 7 drives the flip frames 9 and the photovoltaic panel 11 to fold. After folding, the latches 8 are closed. The whole device is easy to move with the cooperation of the universal brake wheel 3 and the directional wheel 4.
