[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] like Figure 1 As shown, in one embodiment, a flexible support load testing device 10 is provided, including a support body 100, a load-bearing component 200, and a first stress adjustment mechanism 300. The load-bearing component 200 includes a connecting cable 210, which is suspended on the support body 100. The first stress adjustment mechanism 300 is mounted on the support body 100 and connected to the connecting cable 210. The first stress adjustment mechanism 300 is used to adjust the prestress of the connecting cable 210.

[0029] In the above embodiment, the flexible support load testing device 10 is used by installing the photovoltaic module 20 on the connecting cable 210 and then adjusting the prestress of the connecting cable 210 through the first stress adjustment mechanism 300, so that the test conditions of the photovoltaic module 20 on the connecting cable 210 are consistent with the actual use conditions of the photovoltaic module 20, ensuring that the tested load is more stable and reliable, and improving the accuracy of the test of the flexible support load testing device 10.

[0030] It should be noted that the connecting cable 210 is suspended on the support body 100. This can be achieved by having both ends of the connecting cable 210 directly mounted on the support body 100 to suspend it, or by having both ends of the connecting cable 210 mounted on the support body 100 and the first stress adjustment mechanism 300 respectively to suspend it, or by having both ends of the connecting cable 210 mounted on the support body 100 via the first stress adjustment mechanism 300 to suspend it. Suspending the connecting cable 210 means that, except for the fixed connection points at both ends, the rest of the connecting cable 210 does not contact the support.

[0031] The number of connecting cables 210 and the first stress adjustment mechanism 300 can be flexibly adjusted according to actual usage needs.

[0032] like Figure 1 and Figure 2 As shown, the first stress adjustment mechanism 300 further includes a connector 310 and an adjusting member 320. The connector 310 is mounted on the support body 100. One end of the adjusting member 320 is connected to the connector 310, and the other end is connected to the end of the connecting cable 210 near the connector 310. The adjusting member 320 is used to adjust the distance between the connector 310 and the connecting cable 210. Thus, by adjusting the distance between the connector 310 and the connecting cable 210 through the adjusting member 320, the tension of the connecting cable 210 is adjusted, thereby adjusting the prestress of the connecting cable 210. The operation is simple and convenient, improving the practicality of the flexible support load testing device 10.

[0033] It should be noted that adjusting the distance between the connector 310 and the connecting cable 210 can be achieved by adjusting the connection position between the connector 310 and the adjusting member 320, and / or by adjusting the connection position between the connecting cable 210 and the adjusting member 320. Alternatively, the adjusting member 320 can be a telescopic structure that can extend and retract along its own axis, and the adjustment can be achieved by adjusting the axial length of the adjusting member 320.

[0034] In other embodiments, the first stress adjustment mechanism 300 may also be configured as a winding structure, which is mounted on the connecting cable 210 and used to adjust the tension of the connecting cable 210.

[0035] like Figure 1 and Figure 2As shown, optionally, the two ends of the adjusting member 320 are respectively provided with a first threaded portion and a second threaded portion with opposite rotation directions. One end of the connecting member 310 is rotatably connected to the support body 100, and the other end is provided with a third threaded portion that is threadedly connected to the first threaded portion. The end of the connecting cable 210 near the connecting member 310 is provided with a fourth threaded portion 211 that is threadedly connected to the second threaded portion. Thus, rotating the adjusting member 320 in a preset direction can tighten the connecting cable 210, thereby increasing the prestress of the connecting cable 210; rotating the adjusting member 320 in a direction opposite to the preset direction can loosen the connecting cable 210, thereby reducing the prestress of the connecting cable 210, thus improving the ease of operation of the flexible support load testing device 10.

[0036] Specifically, in this embodiment, one of the first and third threaded portions is configured as a threaded hole, and the other is configured as a threaded post. The second threaded portion is configured as a threaded hole or a threaded post, and the fourth threaded portion 211 is configured as an external threaded sleeve or an internal threaded sleeve.

[0037] like Figure 2 As shown, in one embodiment, the first stress adjustment mechanism 300 further includes a first locking member 330 and a second locking member 340. The first locking member 330 is configured to lock the adjusting member 320 and the connecting member 310 together when the prestress on the connecting cable 210 is adjusted to a first preset value. The second locking member 340 is configured to lock the adjusting member 320 and the connecting cable 210 together when the prestress on the connecting cable 210 is adjusted to the first preset value. Thus, when the prestress of the connecting cable 210 is adjusted to the first preset value, the first locking member 330 locks the connecting member 310 and the adjusting member 320 together to ensure that there is no relative movement between the connecting member 310 and the adjusting member 320, and the second locking member 340 locks the connecting cable 210 and the adjusting member 320 together to ensure that there is no relative movement between the adjusting member 320 and the connecting cable 210, thereby ensuring that the connecting cable 210 can maintain the prestress at the first preset value and improving the accuracy of the test by the flexible support load testing device 10.

[0038] The value of the first preset value can be flexibly adjusted according to actual needs. Both the first locking member 330 and the second locking member 340 can be equipped with locking buckles, locking clamps, or other locking structures. The number of the first locking member 330 and the second locking member 340 can be flexibly adjusted according to actual usage needs.

[0039] like Figure 2As shown, optionally, the adjusting member 320 is configured as an adjusting sleeve. Both the first and second threaded portions are configured with first threaded holes 321, with the two first threaded holes 321 located on the end faces of both ends of the adjusting sleeve. The outer walls of both ends of the adjusting sleeve are provided with second threaded holes 322, which communicate with the two first threaded holes 321. The first locking member 330 and the second locking member 340 are both configured as self-tapping set screws. These two self-tapping set screws are configured to pass through the two second threaded holes 322 when the prestress on the connecting cable 210 is adjusted to a first preset value, and abut against the third and fourth threaded portions 211 respectively.

[0040] like Figure 1 and Figure 3 As shown, in one embodiment, there are two connecting cables 210, which are spaced apart along a first direction. The load-bearing assembly 200 also includes a load-bearing cable 220 and a fixed support frame 230. The load-bearing cable 220 is suspended on the support body 100 and located below the two connecting cables 210. The fixed support frame 230 is detachably connected to the load-bearing cable 220 and the two connecting cables 210. The flexible support load testing device 10 also includes a second stress adjustment mechanism 400, which is mounted on the support body 100 and connected to the load-bearing cable 220. The second stress adjustment mechanism 400 is used to adjust the prestress of the load-bearing cable 220. In this way, the load-bearing cable 220 can structurally level the two connecting cables 210 through the fixed support frame 230, thereby increasing the reliability of the photovoltaic module 20 and improving the accuracy of the test by the flexible support load testing device 10. In addition, the two connecting cables 210, the load-bearing cable 220 and the fixed support frame 230 cooperate to form a three-cable support structure. The fixed support frame 230 can adjust the cable shape of the two connecting cables 210 and the load-bearing cable 220, so that the stress condition of the three-cable support structure used for testing is consistent with the stress condition of the three-cable support structure actually used, thereby improving the accuracy of the test of the flexible support load testing device 10.

[0041] In this specific embodiment, the structure and connection relationship of the second stress adjustment mechanism 400 are the same as or similar to the structure and connection relationship of the first stress adjustment mechanism 300, and will not be described in detail here.

[0042] Specifically, in this embodiment, two connecting cables 210 and one load-bearing cable 220 form a support space. A fixed support frame 230 is located within the support space. The fixed support frame 230 includes three support rods 231 and three connecting clips 232. The three connecting clips 232 are respectively clamped onto the two connecting cables 210 and the load-bearing cable 220. Adjacent connecting clips 232 are connected by support rods 231, so that the three support rods 231 and the three connecting clips 232 cooperate to form a triangular structure. The lengths of the three support rods 231 are customized according to the actual working conditions, or the three support rods 231 are all set as telescopic structures that can extend and retract along their own axis.

[0043] like Figure 1 and Figure 3 As shown, furthermore, both ends of the two connecting cables 210 are connected to a first stress adjustment mechanism 300. Both ends of the load-bearing cable 220 are connected to a second stress adjustment mechanism 400. All four first stress adjustment mechanisms 300 and two second stress adjustment mechanisms 400 are mounted on the support body 100. Thus, by providing multiple first stress adjustment mechanisms 300 and multiple second stress adjustment mechanisms 400, the prestress on the connecting cables 210 and the load-bearing cable 220 can be adjusted, improving the practicality of the flexible support load testing device 10.

[0044] Specifically, in this embodiment, the connecting cable 210 is detachably connected to the first stress adjustment mechanism 300. The load-bearing cable 220 is detachably connected to the second stress adjustment mechanism 400. Thus, the load-bearing cable 220 and the fixed support frame 230 can be selectively installed according to actual needs, enabling the application of existing two-cable support structures (i.e., support structures with two connecting cables 210 but without load-bearing cables 220 and fixed support frames 230) and three-cable support structures, thus broadening the testing range and improving the load testing device 10 for flexible supports.

[0045] It should be noted that when the flexible support load testing device 10 is used to test the two-cable support structure, only two connecting cables 210 and the corresponding first stress adjustment mechanism 300 need to be installed on the support body 100.

[0046] like Figure 1 and Figure 3As shown, optionally, the support body 100 includes a mounting member 110, a first sliding member 120, and a second sliding member 130. There are two mounting members 110, spaced apart along a direction that forms an angle with the first direction. Each mounting member 110 has two first sliding members 120 and one second sliding member 130 that can slide along the first direction. Four first stress adjustment mechanisms 300 are correspondingly mounted on the four first sliding members 120. Two second stress adjustment mechanisms 400 are correspondingly mounted on the two second sliding members 130. Thus, by sliding the first sliding members 120 and / or the second sliding members 130 on the mounting member 110, the spacing between the two connecting cables 210 and the spacing between the connecting cable 210 and the load-bearing cable 220 can be adjusted, thereby adapting to various installation conditions of photovoltaic modules 20 and improving the practicality of the flexible support load testing device 10.

[0047] Specifically, in this embodiment, the mounting member 110 can be configured as a groove-shaped structural plate. The first sliding member 120 is located above the mounting member 110, and the second interactive member is located below the mounting member 110. Both the first sliding member 120 and the second sliding member 130 can be configured as sliding blocks and are installed on the mounting member 110 using any of the sliding connection methods in the prior art. The spacing direction between the two mounting members 110 is perpendicular to the first direction. The first direction can be configured as the length direction or the width direction of the bracket body 100.

[0048] like Figure 1 and Figure 3 As shown, optionally, the support body 100 also includes a base 140, on which at least one of the two mounting members 110 is movably mounted, so that the distance between the two mounting members 110 is adjustable. Thus, the distance between the two mounting members 110 can be adapted to the length of the connecting cable 210, meaning that connecting cables 210 of different lengths can be installed on the support body 100 to meet the needs of different working conditions, improving the practicality of the flexible support load testing device 10.

[0049] Specifically, in this embodiment, two mounting members 110 are movably mounted on the base 140 by bolts. When the bolts are not tightened, the mounting members 110 can slide relative to the base 140; when the bolts are tightened, they lock the mounting members 110 and the base 140 together, preventing the mounting members 110 from sliding relative to the base 140. There are two bases 140, and both ends of the two mounting members 110 are connected to the two bases 140 respectively to form a test chamber, within which the load-bearing component is located.

[0050] like Figure 1As shown, in one embodiment, the flexible support load testing device 10 further includes an adapter 500, which is used to assemble the photovoltaic module 20 onto the connecting cable 210. Thus, the adapter 500 can be pre-fixed onto the photovoltaic module 20, and then, during the installation of the photovoltaic module 20, the adapter 500 can be correspondingly installed onto the connecting cable 210, improving the convenience of the flexible support load testing device 10.

[0051] The quantity of adapter 500 can be flexibly adjusted according to actual usage needs. Adapter 500 can be configured as adapter blocks, adapter bases, or adapter clips, etc. Adapter 500 can be fixedly assembled onto the photovoltaic module 20 through methods such as adhesive bonding, snap-fitting, or threaded connection. Adapter 500 can also be fixedly assembled onto the photovoltaic module 20 through methods such as socketing or snap-fitting.

[0052] It should be noted that this application uses the application of the flexible support load testing device 10 to the load testing of photovoltaic module 20 as an example for illustration. In other embodiments, the flexible support load testing device 10 can also be applied to the load testing of other components.

[0053] Optionally, the flexible support load testing device 10 also includes a prestress detection mechanism, which is used to measure the magnitude of prestress on the connecting cable 210 and the load-bearing cable 220.

[0054] The prestress testing mechanism can be any existing mechanism capable of measuring the magnitude of prestress on the steel cable.

[0055] Optionally, the flexible support load testing device 10 also includes a pressure-applying component, which is used to apply pressure to the photovoltaic module 20. Specifically, the pressure-applying component can be a pressure cylinder or multiple weighted sandbags. According to the test requirements, the pressure-applying component is used to apply pressure to the photovoltaic module 20, thereby simulating the stress situation after the connecting cable 210 and the photovoltaic module 20 are assembled.

[0056] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0057] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0059] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0060] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0061] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
