Description

Technical Field

[0001] This application belongs to the technical field of engineering measurement auxiliary equipment, specifically relating to a platform and its usage method for quality control and inspection of photovoltaic bracket installation. Background Technology

[0002] In existing photovoltaic projects, photovoltaic mounting systems generally adopt a "foundation + support" installation method. By constructing an artificial "free surface," the installation of photovoltaic panels is ensured to be unaffected by environmental conditions such as terrain. While this installation method solves the environmental adaptability problem of photovoltaic panel deployment, it also significantly increases the technical difficulty of construction measurement and quality acceptance, making it difficult for existing measurement methods to meet the actual engineering needs. Specifically, the following technical defects exist:

[0003] Firstly, the stability of measurement points is poor, and the operation is difficult. Photovoltaic project construction scenarios are complex and varied, and the working environment varies significantly under different modes. For example, the fishery-solar hybrid project requires measurement operations to be carried out on a floating vessel. However, existing measuring instruments such as total stations are difficult to set up with high quality on unstable carriers such as floating vessels, which leads to easy deviation of measurement points, greatly increases the difficulty of measurement operations, and seriously affects the accuracy of measurement data, making it impossible to provide reliable positioning basis for the construction of photovoltaic support foundations.

[0004] Secondly, the quality acceptance process is inefficient. After the photovoltaic support system is installed, the purlins and other support components intertwine to form a complex spatial structure. Current quality acceptance methods, which rely on traditional tripods with ground-mounted measuring instruments, are limited by component obstructions and measurement angles, making it impossible to complete the installation quality inspection of a single photovoltaic array or even multiple arrays in one go. To cover all acceptance points, the measuring instruments must be moved multiple times and repeatedly adjusted, increasing the workload of acceptance personnel, significantly extending the acceptance cycle, and slowing down the overall construction progress.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See also Figure 1-3 As shown, according to a first aspect embodiment of this application, a platform for quality control and inspection of photovoltaic bracket installation is provided, comprising: Fixing base 1 is mounted on the purlin of the photovoltaic bracket; Lifting component 2, which is mounted on the fixed base 1, is used to provide vertical adjustment; Support platform 3, which is rotatably mounted on lifting assembly 2; A multi-degree-of-freedom leveling component 4 is disposed on the support platform 3. A measuring instrument 5 is disposed on the multi-degree-of-freedom leveling component 4. The multi-degree-of-freedom leveling component 4 is used to adjust the measuring instrument 5 to a horizontal state.

[0024] In this technical solution, the platform for quality control and inspection of photovoltaic bracket installation includes a fixed base 1, a lifting assembly 2, a support platform 3, a multi-degree-of-freedom leveling assembly 4, and a measuring instrument 5. The fixed base 1 is installed on the steel purlins of the photovoltaic bracket, providing a stable foundation for the entire device after installation. The lifting assembly 2 is connected to the fixed base 1 and rotatably connected to the support platform 3, used to adjust the height of the measuring instrument 5 according to usage requirements. The support platform 3 is rotatably positioned at the top of the lifting assembly 2, enabling preliminary fine-tuning of the horizontal direction of the measuring instrument 5. The multi-degree-of-freedom leveling assembly 4 is installed between the support platform 3 and the measuring instrument 5, providing higher precision horizontal adjustment to ensure the adjusted measuring instrument 5 is level, thus improving measurement accuracy. The lifting assembly 2 and the support platform 3 are rotated and installed between the measuring instrument 5 and the fixed base 1 via the multi-degree-of-freedom leveling assembly 4. The operator can first set the instrument height through the lifting assembly 2, then manually rotate the support platform 3 to align the measuring instrument 5 with the target area, and finally perform the final leveling through the multi-degree-of-freedom leveling assembly 4. After leveling, the measuring instrument 5 can be used for measurement. The operation process is simple and convenient, and the leveling accuracy of the measuring instrument 5 is high, ensuring the accuracy and reliability of the final measurement results of the measuring instrument 5.

[0025] The lifting component 2 allows the measuring instrument 5 to flexibly adjust its observation height to avoid obstruction by dense supports or cables and obtain a clear line of sight for measurement.

[0026] In one embodiment, the lifting assembly 2 includes: A lifting assembly is mounted on the fixed base 1. The lifting assembly includes an outer fixed rail 21, a middle fixed rail 22, and an inner fixed rail 23 that can slide relative to each other. Positioning pin 24 is disposed between the outer fixed rail 21 and the intermediate fixed rail 22 and between the intermediate fixed rail 22 and the inner fixed rail 23, and is used to lock the extension and retraction state between the outer fixed rail 21 and the intermediate fixed rail 22 and between the intermediate fixed rail 22 and the inner fixed rail 23.

[0027] In this technical solution, the lifting assembly includes an outer fixed rail 21, a middle fixed rail 22, an inner fixed rail 23, and positioning pins 24. The positioning pins 24 are respectively installed at the connection points between the outer fixed rail 21 and the middle fixed rail 22, and between the middle fixed rail 22 and the inner fixed rail 23. After the lifting assembly completes its extension and retraction adjustment, the relative positions of the fixed rails are locked, ensuring stable lifting. The outer fixed rail 21, the middle fixed rail 22, and the inner fixed rail 23 can slide relative to each other, enabling multi-stage extension and retraction of the lifting assembly, thereby allowing the measuring instrument 5 to adjust to different heights. When the lifting assembly is adjusted to the target extension and retraction state, adjusting the positioning pins 24 quickly locks the relative positions between the outer fixed rail 21 and the middle fixed rail 22, and between the middle fixed rail 22 and the inner fixed rail 23, thus ensuring stable height and improving the stability of the support for the measuring instrument 5.

[0028] Among them, the sliding parts of the outer fixed rail 21, the middle fixed rail 22 and the inner fixed rail 23 can be equipped with guide structures. For example, a fixed frame is installed between the outer fixed rail 21, the middle fixed rail 22 and the inner fixed rail 23 on both sides, and steel balls are installed in the fixed frame to realize the relative sliding between the outer fixed rail 21, the middle fixed rail 22 and the inner fixed rail 23. At the same time, multiple positioning holes can be evenly opened on the outer fixed rail 21, the middle fixed rail 22 and the inner fixed rail 23. The positioning pin 24 cooperates with the positioning hole to realize multi-position locking, making height adjustment more convenient and realizing flexible adjustment of the height of the measuring instrument 5 according to the usage requirements, and avoiding obstacles from blocking the measuring end of the measuring instrument 5.

[0029] In one embodiment, the two sides of the support platform 3 are connected to the inner fixed rail 23 via a connecting shaft 6, and the connecting shaft 6 is provided with a one-way bearing 7.

[0030] In this technical solution, the support platform 3 is connected to the inner fixed rail 23 on both sides via a connecting shaft 6, allowing the support platform 3 to rotate around the connecting shaft 6. This, in turn, drives the measuring instrument 5 mounted above to adjust its angle, meeting the requirements of different measuring angles during the quality inspection of photovoltaic bracket installation. The connecting shaft 6 is a one-way bearing 7, which has the characteristics of unidirectional rotation and reverse locking. By using the connecting shaft 6, after adjusting to the target height, the initial horizontal adjustment of the measuring instrument 5 is achieved by rotating the support platform 3.

[0031] In one embodiment, a circular level 8 is provided on the support platform 3.

[0032] In this technical solution, a circular level 8 is installed on the support platform 3. The circular level 8 is used to assist the operator in quickly completing the preliminary horizontal calibration of the support platform 3. When rotating the support platform 3, the operator can observe the offset state of the bubble in the circular level 8 to determine the direction of the horizontal deviation of the support platform 3. Then, by adjusting the rotation angle of the support platform 3, the bubble is centered, achieving the preliminary leveling of the support platform 3 and further improving the measurement accuracy of the measuring instrument 5.

[0033] Among them, the circular level 8 is installed on the side wall of the support platform 3. Its connection with the support platform 3 is made by embedding or bolt fastening to ensure a firm connection and prevent displacement or falling off during the rotation of the support platform 3 or on-site vibration, thus ensuring the reliability of the rough level benchmark.

[0034] In one embodiment, the multi-degree-of-freedom leveling component 4 includes: First mounting plate 41, the first mounting plate 41 is disposed on the support platform 3; The second mounting plate 42 is disposed on the first mounting plate 41, and the measuring instrument 5 is disposed on the second mounting plate 42; A leveling drive component 43 is provided, and multiple leveling drive components 43 are respectively disposed between the first mounting plate 41 and the second mounting plate 42. The two ends of the leveling drive component 43 are rotatably connected to the first mounting plate 41 and the second mounting plate 42 respectively. A dual-axis tilt sensor 44 is disposed on the second mounting plate 42 and is used to detect the tilt angle of the second mounting plate 42. The central control unit 45 is used to receive the tilt angle signal of the second mounting plate 42 detected by the dual-axis tilt sensor 44, and generate corresponding control commands according to the signal. The plurality of leveling drive members 43 are controlled by the central control unit 45 and perform telescopic movements according to the control commands to drive the second mounting plate 42 to reach and maintain a horizontal state.

[0035] In this technical solution, the multi-degree-of-freedom leveling component 4 is installed on the support platform 3, which can automatically level the second mounting plate 42, thereby ensuring that the measuring instrument 5 installed on it is in a horizontal working state. Specifically, the multi-degree-of-freedom leveling component 4 includes a first mounting plate 41, a second mounting plate 42, multiple leveling drive components 43, a dual-axis tilt sensor 44, and a central control unit 45. The first mounting plate 41 is set on the support platform 3, and the second mounting plate 42 is used to support the measuring instrument 5 and is set above the first mounting plate 41. The multiple leveling drive components 43 are evenly distributed between the first mounting plate 41 and the second mounting plate 42, and their two ends are rotatably connected to the first mounting plate 41 and the second mounting plate 42 respectively. Through the rotatable connection, the angle change during the leveling process can be adapted to ensure that the extension and retraction movement of the leveling drive components 43 can be converted into spatial posture adjustment of the second mounting plate 42. A dual-axis tilt sensor 44 is mounted on the second mounting plate 42, capable of detecting the tilt angle of the second mounting plate 42 in two vertical directions in real time. The detected angle signals are converted into electrical signals and transmitted to the central control unit 45. Upon receiving the signals, the central control unit 45 analyzes and calculates using a built-in algorithm to determine the required adjustment displacement for each area of ​​the second mounting plate 42, and then generates corresponding control commands, which are sent to each leveling drive component 43. Each leveling drive component 43 executes differentiated telescopic movements according to the control commands, driving the second mounting plate 42 to adjust its posture through multi-point coordinated driving until it reaches and maintains a horizontal state. Compared to traditional manual leveling methods, this multi-degree-of-freedom leveling component 4 eliminates the need for repeated manual calibration by operators, significantly reducing operational difficulty and improving leveling accuracy and efficiency. It is particularly suitable for the complex measurement environment of photovoltaic support sites. Even if the support platform 3 experiences posture shifts due to factors such as on-site vibration or slight deformation of the support, the dual-axis tilt sensor 44 can detect and trigger the leveling action in real time, ensuring that the second mounting plate 42 remains horizontal, providing a stable working reference for the measuring instrument 5, and guaranteeing the reliability of the measurement data.

[0036] Among them, multiple leveling drive components 43 are evenly distributed at the four corners of the first mounting plate 41 and the second mounting plate 42, so that the force on the second mounting plate 42 is more balanced and the mounting plate is not deformed due to force concentration during the leveling process. At the same time, the rotating connection structure between the leveling drive component 43 and the two mounting plates eliminates mechanical interference during the leveling process and ensures the smoothness of the leveling action.

[0037] Among them, the leveling drive component 43 can be an electric push rod, which facilitates electrical signal linkage with the central control unit 45; at the same time, the multi-degree-of-freedom leveling component 4 can also be equipped with a drive power supply to provide stable power to the dual-axis tilt sensor 44, the central control unit 45 and the leveling drive component 43.

[0038] In one embodiment, a linear guide rail 9 is provided between the support platform 3 and the first mounting plate 41. The linear guide rail 9 includes a slide rail 91 and a slider 92. The slide rail 91 is disposed on the support platform 3, and the slider 92 is slidably disposed on the slide rail 91 and connected to the first mounting plate 41.

[0039] In this technical solution, a linear guide rail 9 is provided between the support platform 3 and the first mounting plate 41 to enable fine-tuning of the horizontal direction of the first mounting plate 41, the multi-degree-of-freedom leveling component 4 above it, and the measuring instrument 5. The linear guide rail 9 includes a slide rail 91 and a slider 92. The slide rail 91 is fixedly mounted on the support platform 3, and the slider 92 is slidably mounted on the slide rail 91. The top surface of the slider 92 is fixedly connected to the first mounting plate 41 to ensure that the measuring instrument 5 can be moved. During the on-site measurement and installation of the photovoltaic support, when the measurement position needs to be changed horizontally, the operator does not need to disassemble and rebuild the entire device. They only need to push the first mounting plate 41, and the slider 92 can slide along the slide rail 91 to drive the measuring instrument 5 to make fine-tuning in the horizontal direction.

[0040] Among them, the support platform 3 is rotated through the connecting shaft 6 and the one-way bearing 7, which can adjust the pitch angle of the measuring instrument 5. The linear guide rail 9 realizes the horizontal translation fine adjustment. The combination of the two makes the adjustment range of the measuring instrument 5 more comprehensive and can adapt to the complex on-site environment where photovoltaic support components are intertwined.

[0041] In some embodiments, a limiting component is also installed on the slider 92. The limiting component is a limiting bolt, which is installed on one side of the slider 92. When the slider 92 moves to the target position, the limiting bolt can be rotated so that the limiting bolt contacts the slide rail 91, thereby limiting the slider 92.

[0042] In one embodiment, the fixing base 1 is a magnetic base, which is used to attach to the purlin of the photovoltaic bracket.

[0043] In this technical solution, the fixing base 1 is a magnetic base, which can be quickly and stably attached to the purlin of the photovoltaic bracket through magnetic attraction. This magnetic base is suitable for the characteristic that the purlins of the photovoltaic bracket are mostly made of steel. It can achieve rapid positioning and fixing of the device without the need for additional drilling or welding of fasteners on the bracket, which greatly simplifies the on-site installation work.

[0044] The magnetic mounting base 1 typically integrates a multi-layer magnetic circuit base body and a control switch. Operators simply need to attach the base to the channel steel of the photovoltaic bracket purlin or a designated steel part, and activate the magnetic function by turning on the switch. The multi-layer magnetic circuit then generates a strong attraction force, causing the mounting base 1 to fit tightly against the purlin, forming a stable connection. This magnetic fixing method is not only convenient, eliminating the need for complex tools such as wrenches and hammers, but also avoids damage to the original structure of the photovoltaic bracket, ensuring the structural integrity and load-bearing safety of the bracket.

[0045] In one embodiment, the second mounting plate 42 is further provided with a plurality of mounting holes.

[0046] In this technical solution, the second mounting plate 42 is also provided with multiple mounting holes for fixing the measuring instrument 5. These holes are compatible with different types and specifications of measuring instruments 5, enabling quick and stable installation. They can also be used to install various instruments such as levels, laser levels, and laser rangefinders. Operators can select the corresponding mounting hole position according to the actual model of the measuring instrument 5 being used, and securely connect the instrument base to the second mounting plate 42 using bolts or other fasteners, thus improving installation efficiency.

[0047] In one embodiment, the measuring instrument 5 is a total station.

[0048] See also Figure 4 As shown, the second aspect of this application also provides a method for using a photovoltaic support frame for quality control and inspection during installation. The photovoltaic support frame for quality control and inspection using the technical solution of the first aspect includes the following steps: S1. Fix the fixing seat 1 to the designated position on the purlin of the photovoltaic bracket.

[0049] In this technical solution, since the fixing seat 1 adopts a magnetic base, the operator first determines the measurement reference point on the photovoltaic bracket purlin, turns on the base switch to activate the magnetic function, and then the fixing seat 1 can be stably fixed on the photovoltaic bracket purlin. In this process, there is no need to drill or weld additional holes on the bracket, which avoids damage to the original structure of the photovoltaic bracket and can quickly complete the fixing. At the same time, the magnetic fixing method makes the fixing seat 1 and the rigid purlin more stable, reducing the shaking problem caused by the soft foundation of traditional ground installation.

[0050] S2. Adjust the lifting component 2 to adjust the height of the support platform 3 and the measuring instrument 5, and perform coarse horizontal positioning of the measuring instrument 5 by rotating the support platform 3.

[0051] In this technical solution, the lifting assembly 2, through the sliding cooperation of the outer fixed rail 21, the intermediate fixed rail 22, and the inner fixed rail 23, can adjust the height of the support platform 3 as needed. After the height adjustment is completed, the telescopic state between the outer fixed rail 21, the intermediate fixed rail 22, and the inner fixed rail 23 is locked by the positioning pin 24 to ensure height stability. Subsequently, the support platform 3 is rotated, causing the measuring instrument 5 to adjust the angle in the horizontal direction, and the circular level 8 is used to complete the coarse horizontal adjustment of the support platform 3.

[0052] S3. Activate the multi-degree-of-freedom leveling component 4. The central control unit 45 generates a control signal based on the tilt angle of the second mounting plate 42 detected by the dual-axis tilt sensor 44, and drives the leveling drive component 43 to make the second mounting plate 42 and the measuring instrument 5 reach and maintain a horizontal state.

[0053] In this technical solution, after the horizontal coarse adjustment is completed, the central control unit 45 generates a control signal based on the tilt angle of the second mounting plate 42 detected by the dual-axis tilt sensor 44, and drives the leveling drive 43 to make the second mounting plate 42 and the measuring instrument 5 reach and maintain a horizontal state. After the multi-degree-of-freedom leveling component 4 is activated, the dual-axis tilt sensor 44 installed on the second mounting plate 42 will detect the tilt angle of the plate in the X and Y vertical directions in real time, and convert the angle signal into an electrical signal and transmit it to the central control unit 45. The central control unit 45 quickly calculates the required adjustment displacement of each corner of the second mounting plate 42 through the built-in algorithm, and then generates differentiated pulse control signals, which are transmitted to multiple leveling drive components 43 respectively. Each leveling drive component 43 performs a telescopic action according to the control signal, pushing the second mounting plate 42 to adjust its spatial posture. The entire leveling process is fully automated and requires no manual intervention. When the dual-axis tilt sensor 44 detects that the levelness of the second mounting plate 42 meets the standard, the central control unit 45 issues a stop signal, and the leveling drive component 43 locks the current state, so that the measuring instrument 5 always remains in a horizontal working state, ensuring the accuracy of the measurement data.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application.
