Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic power generation technical field, concretely is a kind of folding photovoltaic board strip base support structure. BACKGROUND

[0002] Solar photovoltaic system, also known as photovoltaic, refers to the facilities that convert solar energy into direct-current electric energy by using the photovoltaic effect of photovoltaic semiconductor materials. In recent years, due to the increasing construction and investment needs of China's electric power, telecommunications, mobile, and network communication, traditional photovoltaic power stations are generally built outdoors and installed on the ground through supports. Building a photovoltaic power station on the ground requires ground treatment, the construction of supports, and other processes. The station construction period is long, the construction load is high, and the setting to ground treatment, support installation, and photovoltaic panel installation require more professional division of labor. There are many problems in the professional connection during on-site construction, which further leads to the demand for mobile and easy-to-install photovoltaic systems to support agricultural and water resource management plans for construction sites, emergency areas, and off-grid charging stations to provide auxiliary power. They can also serve as additional power sources to support existing generators or power remote areas. Their ability to operate in grid-connected and off-grid environments further expands their utility, meeting the needs of activities, sites, and communities that require reliable and sustainable power solutions.

[0003] Most existing solutions involve folding multiple photovoltaic panels relative to each other to form a structure consistent with the size of a standard container. The folded photovoltaic panels are then transported to the designated installation location by a transport vehicle and finally deployed linearly at the installation location. This deployment process is relatively simple and can be completed by 3-4 installers in a day, achieving the effect of rapid deployment and power generation.

[0004] For example, a mobile folding solar photovoltaic power generation device with publication number CN219780087U includes a bottom plate, a front side plate, a rear side plate, and a top plate. A first mounting bracket is provided on the bottom plate, and a first telescopic frame and a second telescopic frame are vertically arranged with the first mounting bracket, with the first telescopic frame and the second telescopic frame arranged at both ends of the first mounting bracket. Sliding grooves are provided on the first telescopic frame and the second telescopic frame. A telescopic frame body is provided on the first mounting bracket, which includes a solar panel mounting frame for setting solar panels, a first connecting plate, and a second connecting plate. A first fixing member is provided on one side of the solar panel mounting frame, and a second fixing member is provided on the other side of the solar panel mounting frame. Adjacent solar panel mounting frames are connected by the first connecting plate and the second connecting plate. A support member connected with a sliding block is provided on the first connecting plate, and the sliding block is arranged in the sliding groove and can move along the sliding groove. The device is transported in a box and utilizes its folding structure to achieve rapid installation on site, save installation time, and achieve the purpose of rapid use.

[0005] However, the above-mentioned solutions have the following disadvantages: However, the above-mentioned solutions have the following disadvantages:

[0006] 1. The photovoltaic panel hinge position of the above patent adopts the traditional wheel support. When unfolding and erecting, it is necessary to lay the slide groove under the support wheel in advance. During installation, the slide groove needs to be spliced ​​and placed first, which wastes a lot of installation time.

[0007] 2. The above-mentioned patent uses a wheel support combined with a sliding groove for deployment, which requires a high degree of flatness of the installation location. If the ground at the installation location is not flat, part of the sliding groove will be suspended in the air, making it difficult to provide a stable support effect. Utility Model Content

[0008] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by replacing the original wheeled support method with a support base. The support base directly contacts the ground, and during the unfolding of the photovoltaic panel, friction between the support base and the ground prevents damage caused by direct dragging and friction between the frame and the photovoltaic panel. Furthermore, the unfolding process can be completed without pre-laying a chute, simplifying use, saving installation time, and improving efficiency. By setting a first and second connecting rod, the frame, first hinge, first connecting rod, and second connecting rod form a parallelogram connecting rod, ensuring the first hinge and support base remain vertical during the unfolding process, preventing the support base from tipping over and causing damage to the frame and photovoltaic panel due to dragging and friction. The adjustment groove and fastening bolts allow for adjustment of the extended length of the support legs on uneven ground, ensuring stable contact between the legs and the uneven surface and maintaining the horizontal state of the support base, thus guaranteeing the stability of the frame and photovoltaic panel after installation.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a foldable photovoltaic panel strip base support structure, including a frame, multiple frames are arranged at an angle to each other, the bottoms of adjacent frames are hinged together by a first hinge, the tops of adjacent frames are hinged together by a second hinge, a photovoltaic panel is fixedly connected inside each frame, and a support strip base for supporting the structure is fixedly connected to the bottom of each first hinge.

[0010] Furthermore, each of the first hinges is hinged to two first links at both ends, and the ends of the two first links away from the first hinges are hinged to second links, and the end of each second link away from the first link is hinged to the corresponding side of the frame.

[0011] Furthermore, two sets of legs are fixedly connected to both ends of the support strip base, and the end of each set of legs does not exceed the range of the first hinge.

[0012] Furthermore, the end of each of the aforementioned legs is bent upwards and tilted upwards.

[0013] Further, a through pin hole is formed on the vertical part of each of the supporting legs.

[0014] Further, an adjusting slot is formed on the vertical part of each of the supporting legs, and a set of fastening bolts are arranged through the adjusting slots and the supporting strip base between each set of the supporting legs.

[0015] In summary, compared with the prior art, the beneficial effects of the utility model lie in that:

[0016] (1) By arranging the supporting strip base, the original wheel type supporting mode is replaced, the supporting strip base is directly contacted with the ground, and the supporting strip base is rubbed with the ground when the photovoltaic panel is dragged to be unfolded, so that the damage caused by the direct ground rubbing of the frame body and the photovoltaic panel is avoided, and the unfolding work can be completed without laying the sliding groove in advance, which is convenient to use, saves the installation time and improves the installation efficiency.

[0025] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment.

[0026] As shown in Figures 1-5 , a folding photovoltaic panel strip base support structure comprises a frame 10, a plurality of frame 10s are arranged in sequence with their heads and tails connected, a photovoltaic panel 11 is fixedly connected in each frame 10, a first hinge 12 is hingedly arranged between the bottoms of every two adjacent frame 10s, a second hinge 13 is hingedly arranged between the tops of every two adjacent frame 10s, and a support strip base 14 is fixedly connected to the bottom of each first hinge 12.

[0027] By arranging the support strip base 14, the original wheel type support mode is replaced, the support strip base 14 is directly contacted with the ground, and the support strip base 14 is rubbed with the ground when the photovoltaic panel is dragged to be unfolded, so that the damage of the frame 10 and the photovoltaic panel 11 caused by direct ground rubbing is avoided, and the unfolding work can be completed without laying a sliding groove in advance, which is convenient to use, saves installation time and improves installation efficiency.

[0028] As shown in Figure 2 , Figure 3 and Figure 5 , two groups of support legs 15 are fixedly connected to the two ends of the support strip base 14 respectively, the ends of each group of support legs 15 do not exceed the range of the first hinge 12, and the end of each support leg 15 is upwardly bent and raised.

[0029] By arranging the support leg 15, additional support effect can be provided, the support strip base 14 and the first hinge 12 are prevented from toppling, the support strip base 14 can more stably provide support for the frame 10 and the photovoltaic panel 11, and by arranging the end of the support leg 15 to be bent and raised, the end of the support leg 15 is prevented from being stuck due to the obstruction of the ground gully in the process of dragging and unfolding the photovoltaic panel.

[0030] As shown in Figure 2 , Figure 3 and Figure 5 , a through pin hole 18 is formed in each support leg 15 and support strip base 14, an adjusting groove 16 is formed in the vertical part of each support leg 15, and a fastening bolt 17 penetrating through the adjusting groove 16 and the support strip base 14 is arranged between each group of support legs 15.

[0031] By setting the adjusting groove 16 and the fastening bolt 17, the length of the supporting leg 15 can be adjusted when the ground is uneven, so that the supporting leg 15 stably contacts the uneven ground and the horizontal state of the support strip base 14 is ensured, thereby ensuring the stability of the frame body 10 and the photovoltaic panel 11 after being erected. By setting the pin hole 18, a pin can be inserted into the pin hole 18 after the frame body 10 and the photovoltaic panel 11 are erected to firmly fix the support strip base 14 to the ground, thereby improving the stability of the support strip base 14 in supporting the frame body 10 and the photovoltaic panel 11.

[0032] As shown in Figure 1 , Figure 2 and Figure 3 , each first hinge 12 is hingedly connected with two first connecting rods 19 at both ends, respectively, and each first connecting rod 19 is hingedly connected with a second connecting rod 20 at the end away from the first hinge 12. Each second connecting rod 20 is hingedly connected with a corresponding side of the frame body 10 at the end away from the first connecting rod 19. The second connecting rod 20 always maintains a horizontal state. The hinged position of the first connecting rod 19 and the first hinge 12 and the hinged position of the frame body 10 and the first hinge 12 are on the same horizontal plane.

[0033] By setting the first connecting rod 19 and the second connecting rod 20, the frame body 10, the first hinge 12, the first connecting rod 19, and the second connecting rod 20 form a parallelogram connecting rod, which can always maintain the vertical state of the first hinge 12 and the support strip base 14 during the process of dragging and unfolding the photovoltaic panel, thereby avoiding the support strip base 14 from tilting and causing the frame body 10 and the photovoltaic panel 11 to rub against the ground and be damaged.

[0034] In this embodiment, initially, the frame body 10 and the photovoltaic panel 11 are in a folded storage state, and the supporting leg 15 is in the highest position and is fixed. When it is necessary to unfold the photovoltaic panel, an installer drags the outermost frame body 10 to unfold the photovoltaic panel, and then continues to drag it to move to the distal end.

[0035] During this process, the support strip base 14 slides to the distal end together with the photovoltaic panel, and the bottom of the support strip base 14 is separated from the ground and does not rub against the ground. The support strip base 14 isolates the ground from the frame body 10, thereby avoiding the frame body 10 and the photovoltaic panel 11 from directly contacting the ground. During the process of unfolding the frame body 10, the support strip base 14 always maintains a vertical state due to the setting of the first connecting rod 19 and the second connecting rod 20, thereby avoiding the support strip base 14 from tilting and causing the frame body 10 and the photovoltaic panel 11 to rub against the ground. The support strip base 14 can always stably support the frame body 10 and the photovoltaic panel 11.

[0036] Meanwhile, the support leg 15 slides on the ground together with the support base 14. The raised end of the support leg 15 can prevent the end of the support leg 15 from getting stuck by ditches or stones on the ground, or prevent the end of the support leg 15 from directly inserting into the ground when dragging on soft ground, which would prevent the support base 14 from being dragged any further.

[0037] After the frame 10 and photovoltaic panel 11 are fully unfolded, if the ground is uneven, the installer will adjust the corresponding support legs 15 according to the actual undulation of the ground, so that the support legs 15 move down along the direction of the adjustment groove 16 and ensure that each support leg 15 can contact the ground, while ensuring that the support base 14 is in a horizontal state. Then, the installer will tighten the fastening bolts 17 to fix the position of the support legs 15.

[0038] Subsequently, the installers inserted pins into each pin hole 18 to fix the support base 14 and the support leg 15 to the ground, thus completing the installation work.
