[0039] This specification provides an embodiment of a flexible support photovoltaic module IV testing device. Please refer to... Figures 1 to 4 The diagram shows a structural schematic, a cross-sectional view, and two partial schematics of a flexible support photovoltaic module IV testing device according to one embodiment of this specification. Figure 1 and Figure 2 As shown, the flexible bracket photovoltaic module IV testing device includes: testing mechanism 10, connecting seat 20, push rod mechanism 30, support mechanism 40 and handheld column 50.

[0040] like Figure 1 and Figure 3 As shown, the testing mechanism 10 may include four testing instruments arranged symmetrically in a circle. The testing surfaces of the testing instruments are facing downwards. The four testing instruments are distributed symmetrically in a 90° circle, and a single test can simultaneously cover four standard photovoltaic modules. Four sets of IV curve data are collected synchronously, supporting parallel data analysis. The testing efficiency is 300% higher than that of a traditional single testing instrument, avoiding the time-consuming repetitive positioning of single-device, cell-by-cell testing.

[0041] Each detector is equipped with a connecting seat 20 on top. A push rod mechanism 30 is installed between two connecting seats 20 located in the same row. The push rod mechanism 30 may include a push rod and a first drive mechanism. The first drive mechanism can drive the push rod to adjust the horizontal position of the detector 10. After the push rod mechanism 30 is activated, it can adjust the horizontal position of the detector 10. Figure 1 and Figure 3 As shown, the push rod mechanism 30 can push or pull back the connecting seat 20 along the extension direction of the push rod, thereby driving the detector to move along the extension direction of the push rod.

[0042] In one embodiment, before reaching the detection position, the push rod can drive the detector to move inward to reduce the lateral area of ​​the detection mechanism, making it easier for the detection mechanism to reach the detection position. After reaching the detection position, the push rod can be driven to move outward to drive the detector to move outward and contact the corresponding photovoltaic module.

[0043] In one embodiment, the first drive mechanism can be driven by a cylinder. For example, a double-acting cylinder can be used for drive. In one embodiment, the cylinder piston rod can be connected to the push rod via a spherical connector to eliminate lateral forces caused by installation misalignment.

[0044] The support mechanism 40 is located below the push rod mechanism 30 and is used to support the detection mechanism 10.

[0045] A handheld column 50 is installed at the lower end of the support mechanism 40. During photovoltaic module testing, the handheld column 50 can be held by a worker or fixedly installed at the work site. The handheld column 50 may include a telescopic tube and a second drive mechanism. The second drive mechanism can drive the telescopic tube to extend or retract to adjust the vertical position of the testing mechanism 10. After the second drive mechanism is activated, it can drive the telescopic tube to extend or retract, causing the support mechanism 40 to move vertically, thereby adjusting the vertical position of the testing mechanism 10.

[0046] In one embodiment, the second drive mechanism can be driven by a cylinder. For example, a multi-stage telescopic cylinder can be used to drive the telescopic tube to extend or retract.

[0047] In one embodiment, the handle of the handheld column 50 is provided with an anti-slip texture. In another embodiment, the handheld column 50 may also be equipped with a wireless control button to control the raising and lowering of the handheld column 50 and to control the movement of the push rod mechanism 30.

[0048] In one embodiment, the horizontal adjustment range of the detection mechanism 10 is ±30cm (single push rod stroke), and the positioning of any point in the 60cm×60cm plane (positioning accuracy ±1mm) can be achieved through the linkage of push rods on two axes (X / Y direction).

[0049] In one embodiment, the vertical adjustment range of the detection mechanism 10 is 0.5-3m (covering the typical installation height of flexible supports, such as 1.2-2.5m for floating supports on water and 1.5-3m for mountain supports).

[0050] In one embodiment, the collaborative control logic of the detection mechanism 10 can be a preset height-priority → horizontal fine-tuning strategy, first quickly positioning the component height using the handheld column 50, and then fine-tuning the horizontal position using the push rod.

[0051] In one embodiment, the type of flexible support may include: a suspension support, which compensates for height differences by vertical lifting and lowering, and adjusts the detection angle by a horizontal push rod; and a tension membrane support, in which the detector has a built-in tilt sensor to automatically calibrate the detection probe to be perpendicular to the component surface.

[0052] In one embodiment, the flexible support photovoltaic module IV inspection device can also integrate a visual recognition module (such as an industrial camera) to automatically identify the position of the module and achieve fully automatic positioning.

[0053] In one embodiment, the flexible support photovoltaic module IV inspection device can also be equipped with an EL imaging inspection module to simultaneously acquire images of internal defects in the module, thereby achieving the integration of IV characteristics and visual inspection.

[0054] In the above embodiments, the horizontal position adjustment of the connecting base 20 and the detector below it can be achieved, that is, the detection purpose of photovoltaic modules at different horizontal positions can be realized, which can improve the overall working efficiency of the device and thus improve the IV detection efficiency of flexible bracket photovoltaic modules. It can also adjust the vertical direction of the entire support mechanism 40 and the detection mechanism 10 above it, thus avoiding the need to carry portable equipment through ladders for detection, effectively reducing safety hazards and improving the safety of personnel during detection. The above solution solves the problems of low efficiency and easily overlooked manual safety issues when performing IV detection on flexible bracket modules in the prior art, effectively improving the detection efficiency of photovoltaic modules and enhancing the safety of manual detection.

[0055] In some embodiments of this specification, such as Figure 1 , Figure 2 and Figure 4As shown, the support mechanism 40 may include a support base 41, a support column 42, a support seat 43, a top seat 44, a connecting shaft 48, a support plate 45, a base 46, and a fixed seat 47. The support base 41 is located below the push rod and is used to support the push rod mechanism 30. The support base 41 can serve as a stable base for the push rod mechanism 30, ensuring the installation stability of the push rod mechanism 30 and the detection mechanism 10. In one embodiment, the support base 41 may be made of aluminum alloy. The support column 42 is installed at the lower end of the support base 41 and is used to support the support base 41. The support seat 43 is located below the support column 42, and two symmetrically arranged top seats 44 are installed at the lower end of the support seat 43. A support plate 45 is connected to the lower part of each top seat 44. The base 46 is connected to the lower part of the two support plates 45. By setting the top seat 44, support plate 45, and base 46, the transmission path of vertical load through top seat 44 → support plate 45 → base 46 can be made closer to axial force, reducing the bending stress of the support plate 45. The mounting base 47 is installed below the base 46. A hand-held post 50 is installed at the lower end of the mounting base 47.

[0056] like Figure 1 and Figure 2 As shown, in one embodiment, the support area of ​​the support base 43 is larger than the support area of ​​the fixed base 47, so that the support mechanism 40 is generally an inverted trapezoidal structure (wider at the top and narrower at the bottom).

[0057] The inverted trapezoidal structure enhances mechanical stability, increases the base support area, and improves resistance to overturning. The inverted trapezoidal support plate 45 may employ a multi-stage telescopic design, with each stage gradually narrowing for easy disassembly and transportation. The inverted trapezoidal shape allows the handheld column 50 to be positioned closer to the center, facilitating operator grip and reducing arm fatigue. Furthermore, during lifting and lowering, the inverted trapezoidal support structure distributes stress more evenly across components, reducing stress concentration and extending service life.

[0058] The inverted trapezoidal design of the support mechanism 40 effectively solves the problems of equipment stability, terrain adaptability, and operational convenience in the testing of flexible bracket photovoltaic modules through three core advantages: enhanced mechanical stability, optimized spatial adaptability, and improved modular portability. This design not only improves testing accuracy and safety, but also reduces material costs and transportation difficulties through structural innovation. It is a key technological improvement that balances functionality and engineering practicality, and can be widely applied to various high-altitude operations and mobile testing equipment.

[0059] In some embodiments of this specification, the support mechanism 40 may further include a connecting shaft 48 and fasteners 49. The top seat 44 is detachably connected to the support plate 45 via the connecting shaft 48. The support plate 45 is detachably connected to the base 46 via the connecting shaft 48. Fasteners 49 are detachably mounted on the surfaces at both ends of the connecting shaft 48. The connecting seat 20 is detachably connected to the push rod mechanism 30. A handheld column 50 is detachably mounted on the lower end of the fixed seat 47.

[0060] During transportation, the top seat 44 is detachably connected to the support plate 45 via the connecting shaft 48, and the support plate 45 is detachably connected to the base 46 via the connecting shaft 48. Fasteners 49 can be detachably installed on both ends of the connecting shaft 48, allowing the support mechanism 40 to be disassembled into multiple parts, reducing space occupation and transportation costs. Upon arrival at the installation site, the various parts can be quickly assembled using the connecting shaft 48 and fasteners 49, improving installation efficiency. If a component of the support mechanism 40 is damaged or requires upgrades, only the corresponding connecting shaft 48 and fastener 49 need to be disassembled to easily replace the damaged component, without needing to replace the entire support mechanism 40, thus reducing maintenance costs. The detachable connection allows the support mechanism 40 to be adjusted and recombined according to different usage scenarios and needs. For example, the number of support plates 45 can be increased or decreased according to the height requirements of the testing equipment.

[0061] The detachable connection between the connecting seat 20 and the push rod mechanism 30 can be achieved by bolting. Corresponding bolt holes are machined on both the connecting seat 20 and the push rod mechanism 30, and the two are secured together with bolts and nuts. This connection method is simple, reliable, and convenient for disassembly and installation. Alternatively, a snap-fit ​​connection can be used. A snap-fit ​​is provided on the connecting seat 20 or the push rod mechanism 30, and a corresponding slot is provided on the other component. The detachable connection is achieved through the cooperation of the snap-fit ​​and the slot. This connection method is simple to operate and fast. During installation, the position and angle of the push rod mechanism 30 can be adjusted according to the actual situation to ensure that it can accurately support and drive the detection equipment. If the push rod mechanism 30 malfunctions or needs to be upgraded, it can be easily removed from the connecting seat 20 for repair or replacement.

[0062] The detachable connection between the fixed base 47 and the handheld column 50 can be achieved through a threaded connection. The fixed base 47 has an internal thread at its lower end, and the handheld column 50 has an external thread at its upper end. The detachable connection is achieved through the threaded engagement of both. This connection method provides a tight fit and can withstand significant tensile and torque forces. Alternatively, a plug-in connection can be used. The fixed base 47 has a slot at its lower end, and the handheld column 50 has a plug at its upper end. The plug is inserted into the slot and secured using a locating pin or clip. This connection method is convenient for both installation and disassembly, suitable for applications requiring rapid assembly and disassembly. When not in use, the handheld column 50 can be detached from the fixed base 47, reducing the overall length of the support mechanism 40 and facilitating portability. During use, operators can replace the handheld column 50 with different types as needed to meet various operational requirements.

[0063] In some embodiments of this specification, each connector 20 has a countersunk hole on its inner side, and a tapered connecting block is installed on the outer side of the push rod's output shaft, with the tapered connecting block and the countersunk hole having an interference fit. The countersunk hole is located on the inner side of the connector 20, and its shape is adapted to the tapered connecting block. The countersunk hole requires high dimensional accuracy and surface roughness to ensure a good interference fit with the tapered connecting block. Typically, the bottom of the countersunk hole may have a certain rounded corner or chamfer design to avoid damage to the tapered connecting block during installation. The tapered connecting block is installed on the outer side of the push rod's output shaft and is conical in shape. This tapered design allows the tightness of the fit to gradually increase as the tapered connecting block is gradually inserted into the countersunk hole during installation. The taper of the tapered connecting block is a key parameter and needs to be precisely designed according to the specific application scenario and the required connection strength. Its surface is generally smoothed to reduce friction during installation and also helps to improve the sealing performance of the fit. An interference fit refers to a fit where the hole size is smaller than the shaft size. During assembly, a certain external force is applied to press the shaft into the hole, creating pressure and friction between the two to achieve a tight connection. For an interference fit between a countersunk hole and a tapered connecting block, when the tapered connecting block is pressed into the countersunk hole, the inner wall of the countersunk hole undergoes elastic deformation and a certain degree of plastic deformation because the size of the countersunk hole is smaller than the maximum diameter of the tapered connecting block. The tapered connecting block also experiences a certain compressive force. The interaction force generated by this deformation forms a strong connection between the two, effectively transmitting torque and axial force. An interference fit provides a large connection force, ensuring a reliable connection between the push rod and the connecting seat 20. Compared to other connection methods, such as welding or riveting, the tapered connection of an interference fit is relatively convenient for assembly and disassembly. During assembly, a special tool can be used to press the tapered connecting block into the countersunk hole; when disassembly is required, a reverse force can be applied to pull the tapered connecting block out of the countersunk hole. This repeatable assembly and disassembly characteristic makes equipment maintenance and component replacement easier. The interference fit effectively fills the gap between the countersunk hole and the tapered connecting block, providing excellent sealing performance. The tapered connecting block is designed with self-centering capabilities. When the tapered connecting block is inserted into the countersunk hole, its tapered shape automatically adjusts its position, aligning the output shaft of the push rod with the center of the connecting seat 20. This self-centering function improves assembly accuracy and efficiency, reducing problems caused by installation deviations.

[0064] In some embodiments of this specification, the upper end of the support 41 has an installation groove, and the lower end of the push rod is disposed within the installation groove. The mating design of the installation groove of the support 41 and the lower end of the push rod, through three core functions—rigid limiting, uniform load distribution, and rapid positioning—solves the problems of stability and installation efficiency during horizontal adjustment of the testing device. This design not only improves the accuracy and reliability of IV testing of flexible bracket photovoltaic modules, but also reduces operational difficulty and maintenance costs through structural innovation, thereby achieving efficient and reliable testing.

[0065] In some embodiments of this specification, a positioning post is installed at the lower end of the support post 42, and a positioning hole is provided at the center of the support base 43, with the positioning post installed in the positioning hole.

[0066] The design of the positioning column 42 and the positioning hole 43 of the support base, through rapid and accurate positioning, stable vertical load transfer, and quick assembly and disassembly, solves the problems of cumbersome installation, low positioning accuracy, and poor stability of traditional support mechanisms 40. This design not only improves the efficiency and accuracy of IV testing of flexible bracket photovoltaic modules, but also reduces equipment operation and maintenance costs through a modular concept.

[0067] In some embodiments of this specification, slots are provided at both the upper and lower ends of the support plate 45, and the top seat 44 and the base 46 are installed in the slots. The design of the slots in the support plate 45 and the fit between the top seat 44 and the base 46, through geometric limiting, surface contact bearing, and modular assembly / disassembly, solves the problems of low connection efficiency, stress concentration, and difficult maintenance of traditional support mechanisms 40. This not only improves the stability and environmental adaptability of the flexible bracket photovoltaic module IV testing device, but also achieves a balance between lightweight and high strength through structural innovation, enabling efficient and reliable testing.

[0068] In some embodiments of this specification, the circumferential surfaces at both ends of each connecting shaft 48 are provided with external threads, the fastener 49 is provided with internal threads, the connecting shaft 48 and the fastener 49 are connected by threads, and the outer walls at the upper and lower ends of each support plate 45 are provided with grooves, and the fastener 49 is installed in the grooves.

[0069] In the above embodiments, the threaded connecting shaft 48 and the countersunk fastener 49 achieve a balance of high efficiency, reliability, and environmental adaptability in detachable connections through precision threads and concealed installation. This not only solves the problems of traditional exposed threads being prone to corrosion and loosening, but also reduces manufacturing costs and maintenance difficulty through standardization and lightweight improvements, ensuring the long-term stable operation of the support mechanism 40.

[0070] In some embodiments of this specification, a fixing block is installed on the upper end of the output shaft of the handheld column 50, and a fixing hole is opened at the center of the lower end of the fixing seat 47, and the fixing block is inserted into the fixing hole.

[0071] In the above embodiments, the plug-in design of the handheld column 50 fixing block and the fixing hole of the fixing base 47, through geometric positioning, quick insertion and removal, and sealing and vibration resistance, solves the shortcomings of traditional connection methods in terms of efficiency, accuracy, and environmental adaptability. This not only improves the portability and reliability of the flexible bracket photovoltaic module IV testing device, but also enables rapid component replacement and functional expansion through a modular concept.

[0072] In some embodiments of this specification, the first drive mechanism and / or the second drive mechanism may include a cylinder. As a core component of the first / second drive mechanism, the cylinder, through its rapid response, high reliability, and environmental adaptability, can meet the complex testing requirements of flexible support photovoltaic modules. It not only solves the problems of low efficiency and high safety risks associated with traditional testing equipment, but also, through modular design and cost optimization, becomes a key technological support for promoting intelligent and unmanned photovoltaic testing.

[0073] The following is an example of a specific embodiment; please refer to [link / reference]. Figures 1 to 4 The flexible bracket photovoltaic module IV testing device may include: a testing mechanism 10, which includes four testing instruments arranged symmetrically in a circle. Each testing instrument is equipped with a connecting seat 20 above it. A push rod mechanism 30 is detachably installed between two connecting seats 20 in the same row. A support seat 41 is provided below the push rod mechanism 30. A support column 42 is installed at the lower end of the support seat 41.

[0074] The support column 42 supports the support base 41, which in turn supports the push rod mechanism 30. The push rod mechanism 30 ensures the installation stability of the connecting seat 20 and the testing instrument. By disassembling and assembling the support column 42 and the support base 41, the testing mechanism 10 above them can be disassembled and assembled, facilitating assembly and installation. After activating the push rod mechanism 30, the horizontal position of the connecting seat 20 and the testing instrument below it can be adjusted, thus enabling the testing of photovoltaic modules at different horizontal positions. Setting up four testing instruments can improve the overall working efficiency of the device.

[0075] A support base 43 is provided below the support column 42. Two symmetrically arranged top seats 44 are installed at the lower end of the support base 43. A support plate 45 is detachably connected to the lower end of each top seat 44 via a connecting shaft 48. A base 46 is detachably connected to the lower end of the two support plates 45 via a connecting shaft 48. A fixing seat 47 is installed below the base 46. A hand-held column 50 is detachably installed at the lower end of the fixing seat 47. Fasteners 49 can be detachably installed on the circumferential surfaces at both ends of each connecting shaft 48.

[0076] The handheld column 50 provides support for the fixed base 47, which in turn provides support for the base 46. The base 46, in conjunction with the connecting shaft 48, provides support for the base 46. The connecting shaft 48, in conjunction with the support plate 45, provides support for the top seat 44. The top seat 44 provides support for the support seat 43, and the support seat 43 provides support for the components above, thus ensuring the stability of the testing mechanism 10.
