[0002] Photovoltaic panel brackets are an important part of solar power generation systems. They are used to support and fix photovoltaic panels to ensure that they can effectively receive sunlight and convert it into electrical energy. Depending on the installation environment and requirements, the design of photovoltaic panel brackets is also varied, and can be mainly divided into ground brackets, roof brackets, and tracking brackets.

[0003] Stress testing is a very important step in the production process of photovoltaic panel brackets, which helps to ensure the stability and safety of the brackets in actual use. Existing stress testing mainly involves stress testing of individual bracket rods before the brackets are assembled into finished products to confirm the mechanical properties of each bracket rod.

[0031] See also Figure 1 to Figure 7The present invention provides a stress detection device for the production of photovoltaic panel brackets, including a base 101, a fixing component 102, a loading component 103 and a testing component 104, wherein the fixing component 102 is arranged on the base 101, and is used to fix the photovoltaic panel bracket to be produced, and the loading component 103 is arranged above the fixing component 102, and is used to place a load on the fixed photovoltaic panel bracket, and the testing component 104 includes a stress detector 105, a support frame 106, a plurality of force application modules 107 and a control module 108, wherein the support frame 106 is arranged on one side of the base 101, the stress detector 105 is arranged on the photovoltaic panel bracket, and the plurality of force application modules 107 are slidably arranged on the support frame 106, and the control module 108 is used to control the force application module 107 to apply pressure to the force points on the photovoltaic panel bracket.

[0032] In this embodiment, the base 101 serves as the foundation of the entire device. The base 101 provides a stable support platform to ensure the stability of the device during the stress test.

[0033] The fixing assembly 102 is installed on the base 101, and its function is to firmly fix the photovoltaic panel bracket to be produced. The design of this assembly needs to take into account photovoltaic panel brackets of different sizes and shapes to ensure that it can adapt to various types of brackets, while ensuring that the bracket will not move or loosen during the test.

[0034] The loading assembly 103 is located directly above the fixing assembly 102, and its function is to place a preset load on the already fixed photovoltaic panel support. This step simulates the situation where the photovoltaic panel is installed on the photovoltaic panel support.

[0035] The test assembly 104 performs specific stress detection tasks. The stress detector 105 is directly installed at the key position of the photovoltaic panel support to monitor the stress changes of the support in real time when it is subjected to different loads. Through high-precision sensor technology, the stress distribution data can be accurately obtained. The support frame 106 is set up on one side of the base 101, providing a moving track for the force module 107.

[0036] In summary, this stress detection device can not only efficiently complete the stress test of the photovoltaic panel bracket, but also provide strong technical support for improving the quality and reliability of the photovoltaic panel bracket through its precise control and measurement capabilities.

[0037] The fixing assembly 102 includes a sliding plate 109, an adjusting screw 110, a fixing plate 111 and a driving unit 112. The sliding plate 109 is slidably arranged on the base 101. The adjusting screw 110 is threadedly connected to the sliding plate 109 and is rotatably connected to the base 101. The driving unit 112 is arranged on the sliding plate 109, and the fixing plate 111 is connected to the output end of the driving unit 112.

[0038] The sliding plate 109 is mounted on the base 101 and can move smoothly along the surface of the base 101. This design allows the lateral position to be adjusted according to the actual size and shape of the photovoltaic panel support, ensuring that each test can be accurately aligned with the target area.

[0039] The adjusting screw 110 is connected to the sliding plate 109 by threads and is rotatably connected to the base 101. By rotating the adjusting screw 110, the position of the sliding plate 109 can be finely adjusted, thereby achieving accurate fixation of the photovoltaic panel bracket in the longitudinal direction. This mechanism not only improves the fixing accuracy, but also increases the adaptability of the equipment, and can cope with brackets of different specifications.

[0040] The drive unit 112 is mounted on the sliding plate 109 and is the power source of the fixing assembly 102. It can be electrically, pneumatically or hydraulically driven, and the specific choice depends on the needs of the actual application. The main task of the drive unit 112 is to push the fixing plate 111 closer to the photovoltaic panel bracket to be fixed, and finally achieve fastening.

[0041] The fixing plate 111 is connected to the output end of the driving unit 112 and directly contacts the photovoltaic panel support to achieve physical fixation.

[0042] The fixing assembly 102 further includes a return spring 113 , and the return spring 113 is disposed between the driving unit 112 and the fixing plate 111 .

[0043] The return spring 113 is installed between the driving unit 112 and the fixing plate 111 to play the role of buffering and resetting.

[0045] The reel unit 115 is installed above the base 101 and is the power source of the loading assembly 103. It usually includes a motor and a drum, and the motor drives the drum to rotate, thereby realizing the reeling and unreeling of the connecting rope 114. The design of the reel unit 115 needs to ensure sufficient torque and precise control to adapt to the requirements of loads of different weights and sizes.

[0046] The connecting rope 114 is a key component for transmitting force in the loading assembly 103. The loading plate 116: The loading plate 116 is a component directly placed on the photovoltaic panel support, and its function is to simulate the load encountered in actual use. The design of the loading plate 116 needs to consider the following aspects: Weight and size: The weight and size of the loading plate 116 should be determined according to the test standard and the expected application scenario of the photovoltaic panel support to ensure the representativeness and effectiveness of the test.

[0047] Materials and surface treatment: The material of the loading plate 116 should be non-deformable and corrosion-resistant, and the surface treatment should take into account the need to prevent slipping and protect the photovoltaic panel bracket to avoid unnecessary damage during the test.

[0048] Connection method: The loading plate 116 is connected to the winding unit 115 through the connection rope 114, ensuring that it can be smoothly raised and lowered under the drive of the winding unit 115.

[0049] The connecting rope 114 includes a driving rope 117, multiple stabilizing ropes 118 and multiple connecting plates 119. The driving rope 117 is connected to the winding unit 115. The multiple stabilizing ropes 118 are connected to the driving rope 117. The connecting plate has multiple connecting grooves.

[0050] One end of the driving rope 117 is connected to the reel of the winding unit 115, and the other end is connected to the loading plate 116 through a series of guide devices (such as pulleys). The material of the driving rope 117 is usually a high-strength steel wire rope or fiber rope to ensure reliability and durability when bearing heavy loads.

[0051] A plurality of stabilizing ropes 118 are connected to the driving rope 117 and are distributed on both sides of the driving rope 117. The main function of the stabilizing ropes 118 is to ensure that the loading plate 116 remains level during the ascending and descending process to prevent test errors caused by deflection. The number and layout of the stabilizing ropes 118 need to be optimized according to the size and weight of the loading plate 116 to achieve optimal stability.

[0052] The connecting plate is a special middle piece having a plurality of connecting grooves for connecting the loading plate 116 and the photovoltaic panel support. A connecting rod may be provided on the photovoltaic panel support so as to be inserted into the connecting grooves for positioning.

[0053] The stress detector 105 includes multiple stress detection units 120, a data acquisition unit 121 and an alarm unit 122. The multiple stress detection units 120 are installed on the photovoltaic panel bracket, the data acquisition unit 121 is used to connect with the multiple stress detection units 120, and the alarm unit 122 is connected to the data acquisition unit 121.

[0054] The stress detection unit 120 is a sensor installed on the photovoltaic panel bracket, usually using a high-precision strain gauge or optical fiber sensor. These sensors are attached to the key stress-bearing parts of the bracket, such as connection nodes, support beams, etc., to monitor the stress changes in these parts in real time. Each stress detection unit 120 has high sensitivity and response speed, and can capture tiny stress changes.

[0055] The data acquisition unit 121 is the central processing unit of the stress detector 105. It is connected to multiple stress detection units 120 by wire or wireless means to collect data transmitted by each detection unit. The data acquisition unit 121 usually has the functions of data acquisition, storage and processing, can display stress data in real time, and perform data analysis, generate stress distribution diagrams and time curves, etc. In addition, the data acquisition unit 121 can also be connected to an external computer system to realize remote monitoring and analysis of data.

[0056] The alarm unit 122 is connected to the data acquisition unit 121 and is used to issue an alarm when the stress exceeds a preset threshold. The alarm unit 122 can use an audible and visual alarm to promptly remind the operator of potential safety hazards. The alarm threshold can be set according to actual test requirements to ensure that a timely response can be obtained in any abnormal situation.

[0057] The force applying module 107 includes a force applying unit 123, a force sensor 124, a lifting block 125, a fixer 126 and a contact block 127. The lifting block 125 is slidably arranged on the support frame 106. The fixer 126 is arranged on one side of the lifting block 125 to lock the position of the lifting block 125. The force applying unit 123 is arranged on the lifting block 125. The contact block 127 is rotatably arranged at the output end of the force applying unit 123. The force sensor 124 is arranged between the contact block 127 and the force applying unit 123.

[0058] The force unit 123 is the core part of the force module 107, generating and applying pressure. The force unit 123 is usually driven by electricity, pneumatic or hydraulic, and can accurately adjust the size and direction of the force according to the instructions of the control module 108. The design of the force unit 123 needs to consider the range and accuracy of its output force to meet different test requirements.

[0059] The force sensor 124 is installed between the contact block 127 and the force applying unit 123, and is used to monitor the magnitude of the force generated by the force applying unit 123 in real time. The force sensor 124 usually has high precision and high response speed, and can provide real-time feedback on the change of force to ensure the accuracy and stability of the force application. The data of the force sensor 124 is transmitted to the control module 108 through the signal line, and is used to adjust the output force of the force applying unit 123 in real time.

[0060] The lifting block 125 is slidably disposed on the support frame 106 and can move freely in the vertical direction. The sliding track of the lifting block 125 usually adopts a high-precision guide rail and slider system to ensure the smoothness and stability of its movement. The movement of the lifting block 125 is driven by the control module 108 through a motor or a cylinder, and its height position can be accurately adjusted.

[0061] The fixture 126 is disposed on one side of the lifting block 125 and is used to lock the position of the lifting block 125. The fixture 126 is usually provided by a locking screw or an electromagnetic lock, etc., which can ensure that the position of the lifting block 125 remains unchanged during the force application process, thereby avoiding test errors caused by accidental movement. The design of the fixture 126 needs to consider its convenience and reliability of operation.

[0062] The contact block 127 is rotatably arranged at the output end of the force applying unit 123, and is used to contact the force point of the photovoltaic panel bracket. The contact block 127 is usually made of wear-resistant material, and the surface is specially treated to reduce friction and wear. The rotation design of the contact block 127 can ensure good contact with the bracket surface during the force application process, avoiding stress concentration or damage caused by poor contact. The shape and size of the contact block 127 need to be optimized according to the force point of the bracket to ensure uniformity and reliability of force application.

[0063] The control module 108 includes a stress analysis unit 128, a force data acquisition unit 129, a conversion unit 130 and a control unit 131. The stress analysis unit 128 is used to set the load applied to the bracket by wind; the force data acquisition unit 129 is used to obtain the force distribution data of the force point of the bracket after the load is applied; the conversion unit 130 is used to calculate the alternative force data of the detection point based on the force distribution data; the control unit 131 is used to control the operation of the force application unit 123 based on the alternative force data.

[0064] The stress analysis unit 128 is mainly used to set and simulate external forces that may be encountered in actual use, especially the load imposed by wind on the photovoltaic panel bracket. This unit can set the load parameters under different wind speed and wind direction conditions according to actual engineering data and meteorological data. The stress analysis unit 128 can simulate complex wind field environments using stress analysis software. Users can input parameters such as wind speed, wind direction, duration and wind pressure distribution through a graphical interface, and the stress analysis unit 128 will generate corresponding load curves and distribution diagrams based on these parameters to provide a basis for subsequent tests.

[0065] The force data acquisition unit 129 acquires the force distribution data of each force point of the photovoltaic panel support in real time after the load is applied. These data are generated in the stress analysis software and are used to evaluate the key information of the safety and stability of the support structure. These data usually include stress values, stress distribution diagrams and time curves.

[0066] The conversion unit 130 calculates the alternative force data of each detection point based on the force distribution data provided by the force data acquisition unit 129. The alternative force data refers to the conversion of the complex real force situation into a set of simplified force values ​​based on the key force points in order to simplify the force application process and improve the test efficiency in the actual test. Specifically, the key force points on the photovoltaic panel bracket can be identified based on the stress distribution data. The key force points are usually locations with higher stress values ​​or larger stress changes.

[0067] A stress distribution model of the photovoltaic panel bracket is established to describe the stress relationship between each stress point. Commonly used modeling methods include finite element analysis (FEA) and numerical simulation methods. Key features such as maximum stress value, average stress value and stress gradient are extracted from the stress distribution model. These features will be used for subsequent alternative force calculations.

[0068] According to the stress distribution characteristics, the total load is reasonably distributed to each key stress point. The principle of force distribution is to make the stress value of each stress point as close to the actual stress condition as possible.

[0069] Construct a simplified mechanical model to simplify the complex real force situation into a set of force values ​​based on key force points. The simplified model usually adopts the linear combination method.

[0070] The control unit 131 controls the operation of the force applying unit 123 according to the alternative force data provided by the conversion unit 130. The control unit 131 ensures that the stress value of each force-bearing point meets the preset requirements by precisely controlling the output force of the force applying unit 123. The control unit 131 usually adopts a high-performance embedded controller or PLC (programmable logic controller) with powerful data processing capabilities and real-time control functions. The control unit 131 sends control instructions through the communication interface with the force applying unit 123 to adjust the output force of the force applying unit 123. The control unit 131 also has fault detection and self-diagnosis functions, which can stop the test in time when an abnormal situation occurs to protect the safety of equipment and personnel.
