Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and specifically relates to a photovoltaic power generation device. Background Art

[0002] With the rapid development of renewable energy, photovoltaic power generation, as a clean and sustainable energy form, is increasingly being applied in various fields. While the application of photovoltaic panels in existing drilling technologies has certain advantages, it also presents some inconveniences, limiting its widespread use in this field.

[0003] First, traditional photovoltaic units are usually fixed structures, large in size and heavy in weight, which makes them inconvenient to transport and install at the drilling site. Drilling operations are often carried out in remote areas with complex site conditions. The handling and installation of traditional photovoltaic units require a lot of manpower and time, which reduces work efficiency.

[0004] Secondly, in drilling operations, the arrangement of equipment and tools needs to be flexibly adjusted according to the site conditions. Traditional photovoltaic units are inconvenient to transport and cannot adapt to such dynamic changes, resulting in the inability to effectively utilize available space in some cases, which affects the overall flexibility of the operation.

[0005] Based on the above analysis, improving the handling flexibility and assembly speed of photovoltaic units in drilling operations has become a pressing technical challenge. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0025] Example 1: This example provides a photovoltaic power generation device, including at least one set of retractable photovoltaic power generation units 100, preferably one set. The photovoltaic power generation unit 100 includes a photovoltaic panel 101 and a support rod 102. The photovoltaic panel 101 includes multiple panels, and the sides of the multiple photovoltaic panels 101 are provided with a first connector 103. The support rod 102 is provided with a second connector 104. The first connector 103 and the second connector 104 are rotatably connected to form a hinge structure. The multiple photovoltaic panels 101 are connected to the support rod 102 with the cooperation of the hinge structure and can rotate relative to the support rod 102 to achieve folding and unfolding.

[0026] Specifically, multiple photovoltaic panels 101 are rotatably fixed to the support rod 102 via the first connector 103 and the second connector 104. When needed, the photovoltaic panels 101 can be rotated and unfolded relative to the support rod 102 for direct use. When not needed, the photovoltaic panels 101 can be rotated and folded relative to the support rod 102 to reduce the width of the photovoltaic power generation unit 100 and thus reduce its volume. It is understood that, for ease of unfolding and folding, the hinge structure formed by the first connector 103 and the second connector 104 is preferably rotated at an angle of 90°, which facilitates quick unfolding and folding.

[0027] Multiple photovoltaic panels 101 are arranged along the length of the support rod 102 and installed symmetrically or staggered on both sides of the support rod 102. This not only facilitates folding but also reduces the mutual interference between multiple photovoltaic panels 101.

[0028] In summary, this solution adopts a modular design for the photovoltaic power generation device, with each photovoltaic power generation unit 100 designed as a retractable structure. When not in use, it can be folded and stored for easy transportation and storage. When in use, it can be quickly unfolded and fixed in the required position, adapting to different operating environments and spatial layouts, improving operational efficiency and reducing labor costs. Furthermore, when multiple sets of photovoltaic power generation units 100 are used in combination, the modular design allows for the use of individual photovoltaic power generation units 100 as the detection target, facilitating rapid location of abnormal units and improving maintenance efficiency. Therefore, this modular and foldable photovoltaic power generation device effectively solves the inconveniences of using photovoltaic panels 101 in existing drilling technologies, improves operational and maintenance efficiency, reduces labor costs, and promotes the further application of renewable energy in the drilling field.

[0029] like Figure 1 The diagram shown is a front view of a photovoltaic power generation unit 100 provided in this embodiment. In this scheme, the support rod 102 has a straight structure, and multiple photovoltaic panels 101 are arranged along the length of the support rod 102 and symmetrically installed on both sides of the support rod 102.

[0030] like Figure 2 The diagram shown is a front view of another photovoltaic power generation unit 100 provided in this embodiment. In this design, the support rod 102 is a rotatable and foldable structure. The support rod 102 of this structure includes at least a first rod segment 1021 and a second rod segment 1022 of equal size. The first rod segment 1021 and the second rod segment 1022 are connected at their ends by a linkage. The first rod segment 1021 and the second rod segment 1022 can rotate and swing in the horizontal or vertical direction about the linkage as an axis to realize the folding or unfolding of the rod body, thereby realizing the length adjustment of the photovoltaic power generation unit 100. Compared with the support rod 102 of the straight structure, the support rod 102 of this structure can be folded, which can further reduce the volume of the photovoltaic power generation unit 100 and facilitate transportation and storage. It is understood that an equal number of photovoltaic panels 101 should be arranged on the first rod segment 1021 and the second rod segment 1022, and the photovoltaic panels 101 should be arranged in the same position on each rod segment, so as to facilitate the folding of the rod body.

[0031] The first rod segment 1021 and the second rod segment 1022 are arranged in parallel with a parallel gap between them. The linkage is arranged in the parallel gap to connect the first rod segment 1021 and the second rod segment 1022 end to end. The first rod segment 1021 and the second rod segment 1022 rotate and swing in the vertical direction with the linkage as the axis, thereby realizing the folding or unfolding of the rod body.

[0032] The linkage includes a rotating shaft 1023 and a locking member 1024. A shaft hole and a locking hole communicating with the shaft hole are respectively provided at the corresponding ends of the first rod segment 1021 and the second rod segment 1022. Both ends of the rotating shaft 1023 are rotatably fitted into the shaft hole. The locking member 1024 can penetrate into the locking hole to lock the first rod segment 1021 to the rotating shaft 1023 and the second rod segment 1022 to the rotating shaft 1023, improving the stability of the support rod 102 during retraction and extension. In this embodiment, the locking member 1024 is any one of a bolt or a pin. It is understood that the specific folding method of the rod is determined according to the structure of the linkage. In this embodiment, the linkage can also be any one of a conventional hinge, a rotary joint with a locking device, or a ball joint, as long as it enables the relative folding of the first rod segment 1021 and the second rod segment 1022.

[0033] When the first pole segment 1021 and the second pole segment 1022 are arranged in parallel, the largest parallel gap between them is greater than the thickness of at least one photovoltaic panel 101, ensuring that the two pole segments do not interfere with each other during folding and that 180° folding is possible; Figure 3 The figure shows a schematic diagram of the folded state of the photovoltaic power generation unit 100 provided in this embodiment. As can be seen from the figure, when the photovoltaic power generation unit 100 is not in use, it can be folded in two stages to obtain a smaller volume, which facilitates transportation and storage. Specifically, firstly, the photovoltaic panels 101 on the photovoltaic power generation unit 100 are folded relative to the support rod 102 to reduce the width dimension. Secondly, the rod body of the support rod 102 is rotated and folded around the linkage as the axis to reduce the length dimension. After folding, the photovoltaic panels 101 are arranged side by side, and the rod body of the support rod 102 is located at the upper end. The advantage of setting the upper end of the rod body is that it can reduce the gap between the photovoltaic panels 101 after folding, thereby reducing the volume. On the other hand, it can also serve as a force-bearing component to assist workers in handling.

[0034] The first connector 103 is arranged along the length of the photovoltaic panel 101. Of course, it can also be arranged along the width when necessary, depending on the installation space. In this embodiment, the former is preferred, and this arrangement structure can reduce the width of the photovoltaic power generation unit 100.

[0035] The first connector 103 and the second connector 104 are rotatably connected by a pivot, and at least one of them is a movable connector. In this embodiment, the first connector 103 and the second connector 104 are preferably ear-shaped fasteners with shaft holes. After the first connector 103 and the second connector 104 are mated together, the hinge shaft passes through the shaft hole to hinge the first connector 103 and the second connector 104. It can be understood that in order to improve the stability of the photovoltaic panel 101 when it is extended and retracted, the hinge shaft can be a pivot with a locking element, that is, a pivot that automatically locks after being rotated to the correct position. Alternatively, a locking element such as a pin or screw can be provided on the ear-shaped fastener to lock the first connector 103 and the second connector 104 to each other after being rotated to the correct position. Of course, the above is a preferred structure of the first connector 103 and the second connector 104 in this embodiment. Other connectors that can achieve the purpose of this embodiment are also within the protection scope of this embodiment.

[0036] Example 2: This example provides a photovoltaic power generation device. Compared with Example 1, this example includes multiple sets of photovoltaic power generation units 100. This example uses two sets as an example for illustration. Figure 4 As shown, a third connector 105 is provided on the outer side of the photovoltaic panel 101. Two adjacent photovoltaic power generation units 100 are connected by the third connector 105 to achieve overall assembly and splicing. In this embodiment, the third connector 105 is any one of a plug groove, a threaded hole or a flexible connecting strip. In this embodiment, a plug groove is preferred.

[0037] In practical use, when a large-power photovoltaic power generation device is required, two or more photovoltaic power generation units 100 can be assembled into a whole through the plug-in slots; it can be seen that the photovoltaic power generation device in this embodiment not only has the retraction and extension functions of the photovoltaic power generation device described in Embodiment 1, but also can flexibly assemble each unit according to the power demand, thereby improving the convenience of use.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
