Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic supports, and in particular to a foldable photovoltaic support frame. Background Art

[0002] The construction of existing photovoltaic systems usually involves first selecting a site and installing brackets based on the terrain. After completion, the system is basically unable to be moved. However, in some cases, such as short-term electricity needs or frequent changes of location, the existing construction method is costly.

[0003] In response to the above-mentioned problems, there are corresponding improvements in the existing technology. For example, a Chinese patent application with a publication date of 2018-07-20 and publication number CN207638609U discloses a container-type photovoltaic support structure, including a container and a photovoltaic support assembly. The photovoltaic support assembly is composed of a plurality of foldable support units, which are connected by connecting rods. The support units include a plurality of rectangular support frames, front columns and rear columns arranged at the lower part of the support frames, and the support frames are hinged. The front columns and rear columns are connected to the support frames by locating pins. The back of the support frames is provided with grooves, the bottom of the container is provided with guide rails, and the bottom of the photovoltaic support assembly is provided with a bottom support. When folding, the structure is folded from the far end toward the container. First, the locating pins are pulled out and the front and rear columns of the photovoltaic support are placed in the grooves of the support frames. Then, the locating pins are tightened. The locating pins on the support frames are pulled out, and the upper and lower components are folded in half and fixed with the locating pins. Then, the left and right components are folded in half and fixed with the locating pins, and the stacking of the first unit is completed. A bottom bracket is placed under the collapsed modules to support the stacked photovoltaic rack modules. The modules are then pushed into the container, slid along the guide rails, and secured with latches. This solution has the disadvantage of requiring the front and rear columns of each support frame to be disassembled and reassembled one by one to fold or unfold each support frame, and then to store or unfold multiple support frames, making the operation cumbersome and inconvenient. Utility Model Content

[0004] The purpose of this application is to solve the problem of cumbersome and inconvenient operation of foldable photovoltaic support frames in the prior art. Therefore, this application provides a foldable photovoltaic support frame that simplifies operation and improves operational convenience through the synchronous linkage of multiple connected photovoltaic frames. In addition, the connected photovoltaic frames improve connection stability, linkage reliability, and state stability through the connection components.

[0005] The embodiment of the present application provides a foldable photovoltaic support frame, comprising a plurality of photovoltaic brackets connected in sequence, and two connecting components symmetrically arranged on both sides of the photovoltaic brackets;

[0006] The photovoltaic bracket includes a mounting frame, a support column supporting the mounting frame, and two connecting rods symmetrically arranged on both sides of the mounting frame; the connecting rods are cross-rotatably connected to the corresponding side edges of the mounting frame, and one end of the connecting rod is rotatably connected to the rear end of the corresponding side edge of the mounting frame in the previous photovoltaic bracket, and the other end is rotatably connected to the front end of the corresponding side edge of the mounting frame in the next photovoltaic bracket;

[0007] The connecting assembly includes a first connecting rod and a second connecting rod that are cross-rotatably connected; the first connecting rod is also rotatably connected to the two connecting rods connected to the corresponding sides of the photovoltaic bracket, and extends to be connected to one of the support columns connected to the corresponding sides of the photovoltaic bracket, and the connection position is adjustable; the second connecting rod is also rotatably connected to the corresponding sides of the two mounting frames connected to the photovoltaic bracket, and extends to be connected to the other support column connected to the corresponding side of the photovoltaic bracket, and the connection position is adjustable.

[0008] By adopting the above technical solution, multiple photovoltaic brackets are continuously connected in rotation through the mounting frame and the connecting rod, that is, a continuous retractable quadrilateral structure is formed, so that the operation of a single photovoltaic bracket can synchronously link the folding or unfolding of the entire photovoltaic support frame, which simplifies the operation and improves the convenience of operation; and, the sides of the connected photovoltaic brackets are provided with connecting components, that is, the relative edges are cross-connected in the quadrilateral structure, which enhances the connection stability and linkage reliability. At the same time, the connection position of the first connecting rod and the second connecting rod of the connecting component and the corresponding support column is adjustable, that is, the different folding angles of the photovoltaic bracket can be adjusted and fixed accordingly, thereby locking the folding angle, achieving a stable state of the photovoltaic bracket, and thereby improving the stability, reliability and flexibility of the entire photovoltaic support frame.

[0009] In some embodiments, the rotation connection point between the previous connecting rod and the next mounting frame connected to the corresponding sides of the photovoltaic bracket, the rotation connection point between the next connecting rod and the previous mounting frame, and the rotation connection point between the first connecting rod and the second connecting rod are located on the first straight line.

[0010] By adopting the above technical solution, the positions of some rotating connection points in the quadrilateral structure formed by the connected photovoltaic brackets are limited, which further improves the stability of the linked folding of the connected photovoltaic brackets, thereby improving the folding smoothness of the entire photovoltaic support frame and further improving the convenience of operation.

[0012] The adoption of the above technical solution improves the stability of the linkage between the connecting component and the photovoltaic support, thereby further improving the folding smoothness of the entire photovoltaic support frame and further improving the convenience of operation.

[0014] The above technical solution is adopted, that is, the quadrilateral structure formed by the connected photovoltaic brackets is a diamond structure, which further improves the stability of the linked folding of the connected photovoltaic brackets, and makes each installation frame almost horizontal when the entire photovoltaic support frame is fully unfolded. While controlling the site area occupied by the photovoltaic support frame in this state, the edge overlap of the photovoltaic components installed in the installation frame is small, thereby improving the utilization rate of the photovoltaic components; when the entire photovoltaic support frame is fully stored, it can fit the installation frame and shrink into a nearly identical rectangle, with a small overall volume and high regularity, which is convenient for storage in a container.

[0015] In some embodiments, the first connecting rod is rotatably connected to the quarter points of the two corresponding connecting rods; the second connecting rod is rotatably connected to the quarter points of the two corresponding sides of the photovoltaic installation frame.

[0016] The adoption of the above technical solution further improves the stability of the linkage between the connecting component and the photovoltaic support, thereby further improving the folding smoothness of the entire photovoltaic support frame and further improving the convenience of operation.

[0017] In some embodiments, the support column is provided with a plurality of positioning holes along its height direction;

[0018] The first connecting rod, the second connecting rod and the positioning holes corresponding to the support columns are connected through positioning pins.

[0019] The above technical solution improves the convenience of position adjustment of the first connecting rod, the second connecting rod and the corresponding support column, and has a simple structure, low cost and high reliability.

[0020] In some embodiments, a universal wheel is provided at the bottom end of the support column.

[0021] By adopting the above technical solution, the support column is driven to move by the universal wheel, which improves the convenience of movement of the entire photovoltaic support frame and thus improves the convenience of operation.

[0022] In some embodiments, front support assemblies are symmetrically arranged on both sides of the first photovoltaic bracket among the multiple photovoltaic brackets; the front support assembly includes a front support column and a front connecting rod; the front support column is arranged parallel to the support column on the corresponding side of the photovoltaic bracket, and the front end of the corresponding side of the mounting frame in the photovoltaic bracket is connected to the front support column and the position is adjustable; one end of the front connecting rod is rotatably connected to the front support column, and the other end is connected to the support column on the corresponding side of the photovoltaic bracket and the position is adjustable.

[0023] By adopting the above technical solution, the stability of the first photovoltaic bracket is improved through the front support component, thereby improving the stability of the entire photovoltaic support frame; and the front support component can be linked with the photovoltaic bracket, thereby improving the convenience of operation.

[0024] In some embodiments, the last photovoltaic bracket of the plurality of photovoltaic brackets is symmetrically provided with rear support assemblies on both sides; the rear support assembly includes a rear support column, a first connecting rod, a second connecting rod, and a third connecting rod and a fourth connecting rod connected in a cross-rotating manner;

[0025] The rear support column is arranged parallel to the support column on the corresponding side of the photovoltaic bracket;

[0026] The first connecting rod and the second connecting rod are both rotatably connected to the same position of the rear support column, and the first connecting rod is also rotatably connected to the rear end of the corresponding side of the mounting frame in the photovoltaic bracket, and the second connecting rod is also rotatably connected to the rear end of the connecting rod of the corresponding side of the photovoltaic bracket;

[0047] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0048] It should be noted that, for the convenience of structural display, the drawings in this application are schematic diagrams of the assembled photovoltaic support frame and photovoltaic module 1. In addition, usually two photovoltaic units constitute a photovoltaic module 1.

[0049] See Figure 1-2 , Figure 1 A schematic diagram of a partial three-dimensional structure of an embodiment of the present application; Figure 2 This is a side structural diagram of an embodiment of the present application.

[0050] An embodiment of the present application provides a foldable photovoltaic support frame, comprising a plurality of photovoltaic brackets 10 connected in sequence, and two connecting components 20 symmetrically arranged on both sides of the connected photovoltaic brackets 10. The synchronous linkage of the plurality of connected photovoltaic brackets 10 simplifies the operation and improves the convenience of operation. In addition, the connected photovoltaic brackets 10 improve the connection stability, linkage reliability and achieve state stability through the connecting components 20.

[0051] Specifically, the photovoltaic support 10 includes a mounting frame 11, a support column 12 supporting the mounting frame 11, and two connecting rods 13 symmetrically arranged on both sides of the mounting frame 11. Preferably, the support column 12 is height-adjustable to suit different installation requirements.

[0052] The mounting frame 11 is used to mount the photovoltaic module 1. To improve the stability of the mounting frame 11, two support columns 12 are usually provided and symmetrically arranged on both sides of the mounting frame 11.

[0053] The connecting rod 13 is cross-rotatably connected to the corresponding side of the mounting frame 11, and one end of the connecting rod 13 is rotationally connected to the rear end of the corresponding side of the mounting frame 11 in the previous photovoltaic bracket 10, and the other end is rotationally connected to the front end of the corresponding side of the mounting frame 11 in the next photovoltaic bracket 10, forming a continuous retractable quadrilateral structure, so that the operation of a single photovoltaic bracket 10 can synchronously link the folding or unfolding of the entire photovoltaic support frame, without the need to fold or unfold each photovoltaic bracket 10 one by one, which simplifies the operation and improves the convenience of operation.

[0054] The connecting assembly 20 includes a first connecting rod 21 and a second connecting rod 22 that are cross-rotatably connected.

[0055] The first connecting rod 21 is also rotatably connected to the two connecting rods 13 on the corresponding sides of the connected photovoltaic bracket 10, and extends to connect to a supporting column 12 on the corresponding side of the connected photovoltaic bracket 10, and the connection position is adjustable.

[0056] The second connecting rod 22 is also rotatably connected to the corresponding side edges of the two mounting frames 11 in the connected photovoltaic bracket 10 , and extends to connect to another supporting column 12 on the corresponding side edge of the connected photovoltaic bracket 10 , and the connection position is adjustable.

[0057] This method achieves cross-connection of opposing sides of the quadrilateral structure formed by the connected photovoltaic racks 10 through the connecting assembly 20, enhancing connection stability and linkage reliability. Furthermore, the connection positions of the first and second connecting rods 21, 22 of the connecting assembly 20 and the corresponding support column 12 are adjustable, meaning they can be adjusted and fixed accordingly to different folding angles of the photovoltaic rack 10, thereby locking the folding angle and achieving a stable state of the photovoltaic rack 10, thereby improving the stability, reliability, and flexibility of the entire photovoltaic support rack.

[0058] When unfolding, the last photovoltaic bracket 10 can be fixed and the first photovoltaic bracket 10 can be pulled to continuously unfold the middle photovoltaic bracket 10 to the desired angle. Then, by fixing the positions of the first connecting rod 21, the second connecting rod 22 and the corresponding support column 12, the photovoltaic support frame can be stabilized. Compared with the existing structure, this operation does not require each photovoltaic bracket 10 to be unfolded and adjusted in angle one by one, which can greatly simplify the operation. At the same time, when the position is fixed, only a few photovoltaic brackets 10 can be selected for fixing, and the state can also be stabilized, further improving the convenience of operation. It is understandable that the opposite operation can be used to store the photovoltaic support frame.

[0059] In a specific embodiment, the support column 12 is provided with a plurality of positioning holes along its height direction. The first connecting rod 21 and the second connecting rod 22 are connected to the positioning holes of the corresponding support column 12 via positioning pins.

[0060] In this method, the connection position adjustment is achieved through the cooperation of the hole and the pin, which improves the convenience of position adjustment of the first connecting rod 21, the second connecting rod 22 and the corresponding support column 12, and has a simple structure, low cost and high reliability.

[0061] In one embodiment, the rotation connection point of the front connecting rod 13 and the rear mounting frame 11 on the corresponding sides of the connected photovoltaic bracket 10, the rotation connection point of the rear connecting rod 13 and the front mounting frame 11, and the rotation connection point of the first connecting rod 21 and the second connecting rod 22 are located on the first straight line. That is, by limiting the position of some rotation connection points in the quadrilateral structure formed by the connected photovoltaic brackets 10, the stability of the linked folding of the connected photovoltaic brackets 10 is further improved, thereby improving the folding smoothness of the entire photovoltaic support frame and further improving the convenience of operation.

[0062] In one embodiment, the lines connecting the first connecting rod 21, the second connecting rod 22, the two connecting rods 13 and the four rotating connection points of the two mounting frames 11 on the corresponding sides of the photovoltaic bracket 10 form a parallelogram, and one of the sides is parallel to the first straight line, which can improve the stability of the linkage between the connecting component 20 and the photovoltaic bracket 10, thereby further improving the folding smoothness of the entire photovoltaic support frame and further improving the convenience of operation.

[0063] See Figure 3-5 , Figure 3 FIG4( a ) is a schematic diagram of the fully expanded state of the embodiment of the present application; FIG4( a ) is a schematic diagram of the front view of the embodiment of the present application in the fully retracted state; FIG4( b ) is a schematic diagram of the side view of the embodiment of the present application in the fully retracted state; Figure 5 This is a schematic diagram of the state of the embodiment of the present application being stored in the container 2.

[0064] In one embodiment, the length of the connecting rod 13 is the same as the side length of the mounting frame 11, the height of the support column 12 is 1 / 2 the side length of the mounting frame 11, and the midpoint of the connecting rod 13 is rotatably connected to the midpoint of the side of the mounting frame 11, that is, the quadrilateral structure formed by the connected photovoltaic brackets 10 is a diamond structure, which further improves the stability of the linked folding of the connected photovoltaic brackets 10.

[0065] Moreover, this structure allows each mounting frame 11 to be in a nearly horizontal state when the entire photovoltaic support frame is fully unfolded. While controlling the site area occupied by the photovoltaic support frame in this state, it also reduces the edge overlap of the photovoltaic components 1 installed in the mounting frame 11, thereby improving the utilization rate of the photovoltaic components 1.

[0066] This structure also allows the entire photovoltaic support frame to shrink into a nearly identical rectangle when it is fully stored, fitting the mounting frame 11 . The overall volume is small and the regularity is high, making it easy to store in the container 2 .

[0067] In one embodiment, the first connecting rod 21 is rotatably connected to the quarter points of the corresponding two connecting rods 13. The second connecting rod 22 is rotatably connected to the quarter points of the corresponding two sides of the photovoltaic mounting frame 11, further improving the stability of the linkage between the connecting assembly 20 and the photovoltaic support 10, thereby further improving the folding smoothness of the entire photovoltaic support frame and further improving the convenience of operation.

[0068] In one embodiment, a universal wheel 14 is provided at the bottom end of the support column 12, and the universal wheel 14 drives the support column 12 to move, thereby improving the convenience of movement of the entire photovoltaic support frame and further improving the convenience of operation.

[0069] Please see again Figure 2 In one embodiment, front support components 30 are symmetrically arranged on both sides of the first photovoltaic bracket 10 among multiple photovoltaic brackets 10. The front support components 30 improve the stability of the first photovoltaic bracket 10, thereby improving the stability of the entire photovoltaic support frame; and the front support components 30 can be linked with the photovoltaic bracket 10 to improve the convenience of operation.

[0070] In one embodiment, the front support assembly 30 includes a front support column 31 and a front link 32 .

[0071] The front support column 31 is arranged parallel to the support column 12 on the corresponding side of the photovoltaic bracket 10. The front end of the corresponding side of the mounting frame 11 of the photovoltaic bracket 10 is connected to the front support column 31 and the position is adjustable. One end of the front connecting rod 32 is rotatably connected to the front support column 31, and the other end is connected to the support column 12 on the corresponding side of the photovoltaic bracket 10 and the position is adjustable.

[0072] It can be understood that since the front end of the connecting rod 13 of the first photovoltaic bracket 10 is not connected to the photovoltaic bracket 10, the connecting rod 13 can be only half the length of the connecting rod 13 located in the middle, that is, the connecting rod 13 can be rotatably connected to the corresponding support column 12 at its end.

[0073] In one embodiment, rear support components 40 are symmetrically arranged on both sides of the last photovoltaic bracket 10 among multiple photovoltaic brackets 10. The rear support components 40 improve the stability of the last photovoltaic bracket 10, thereby improving the stability of the entire photovoltaic support frame; and the rear support components 40 can be linked with the photovoltaic bracket 10 to improve operational convenience.

[0074] In a specific embodiment, the rear support assembly 40 includes a rear support column 41 , a first connecting rod 42 , a second connecting rod 43 , and a third connecting rod 44 and a fourth connecting rod 45 that are cross-rotatably connected.

[0075] The rear support column 41 is arranged parallel to the support column 12 on the corresponding side of the photovoltaic bracket 10 .

[0076] The first connecting rod 42 and the second connecting rod 43 are both rotatably connected to the same position of the rear support column 41, and the first connecting rod 42 is also rotatably connected to the rear end of the corresponding side of the mounting frame 11 in the corresponding photovoltaic bracket 10, and the second connecting rod 43 is also rotatably connected to the rear end of the connecting rod 13 on the corresponding side of the corresponding photovoltaic bracket 10.

[0077] The third connecting rod 44 is also rotatably connected to the first connecting rod 42 and the connecting rod 13 on the corresponding side of the photovoltaic bracket 10, and extends to connect to the support column 12 on the corresponding side of the photovoltaic bracket 10, and the connection position is adjustable. The fourth connecting rod 45 is also rotatably connected to the corresponding side of the mounting frame 11 of the photovoltaic bracket 10 and the second connecting rod 43, and extends to connect to the rear support column 41, and the connection position is adjustable.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
