Description

Technical Field

[0001] This invention relates to the field of photovoltaic power plant construction technology, and more specifically, to a photovoltaic support column installation verticality detection device and detection method. Background Technology

[0002] In photovoltaic (PV) power generation projects, the verticality of the PV support columns is a crucial factor affecting the structural stability of the support system. Excessive deviation in column verticality can lead to additional stress at the support connection nodes, potentially causing deformation of the support system over long-term operation, thereby affecting the normal operation and lifespan of the PV modules.

[0003] Currently, the verticality detection during the installation of photovoltaic support columns mainly relies on the visual experience of on-site construction personnel, lacking specific measurement methods and quantitative standards, and the technical means are relatively rudimentary.

[0004] The above-mentioned testing methods mainly rely on personal experience, are highly subjective, cannot make accurate quantitative judgments, and are difficult to provide accurate test data for construction personnel to refer to. This makes it difficult for construction personnel to accurately control the verticality of the columns within the range required by the specifications, and can easily lead to quality problems such as stress concentration and deformation of the support system due to excessive verticality deviation.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a photovoltaic support column installation verticality detection device and detection method.

[0007] According to one aspect of this disclosure, a photovoltaic support column verticality detection device includes: Rigid frame; An open-ring member is connected to a rigid frame. The opening of the open-ring member faces away from the rigid frame. The open-ring member is used to hold the outer circumferential surface of the photovoltaic support column. The axial direction of the open-ring member is defined as the first direction. An automatic leveling instrument is installed on the upper part of a rigid frame. The automatic leveling instrument is used to project a laser line downward in a vertical direction. The dial is installed at the bottom of the rigid frame and is positioned opposite the automatic leveling instrument along the first direction. The dial surface is provided with scale lines for indicating verticality deviation. When the first direction is vertical, the laser line is projected onto the zero position of the scale line.

[0008] In one embodiment, the automatic leveling instrument further includes: an inclination sensor, an alarm unit, and a control module, wherein the inclination sensor is used to detect the tilt angle of the photovoltaic support column; The control module stores a preset threshold. When the verticality of the column, calculated from the tilt angle detected by the tilt sensor, is greater than the preset threshold, the control module controls the alarm unit to issue an alarm signal.

[0009] In one embodiment, the scale range of the dial corresponds to a preset threshold. When the verticality of the photovoltaic support column exceeds the preset threshold, the laser line is projected outside the scale range of the dial, and the alarm unit emits an alarm signal; When the verticality of the photovoltaic support column is less than a preset threshold, the laser line is projected onto the scale range of the dial to indicate the verticality deviation value.

[0010] In one embodiment, the photovoltaic support column verticality detection device includes a variety of open ring components with different inner diameters; the rigid frame can be detachably connected to any one of the various open ring components with different inner diameters.

[0011] In one embodiment, the open ring member includes an upper open ring member and a lower open ring member; the upper open ring member and the lower open ring member are disposed on the same side of the rigid frame along a second direction, the second direction being perpendicular to the first direction; the axis of the upper open ring member coincides with the axis of the lower open ring member.

[0012] In one embodiment, the photovoltaic support column verticality detection device further includes a spirit level, which is installed on a rigid frame and used to determine the verticality of the photovoltaic support column.

[0013] In one embodiment, the scale lines are concentric circle scale lines with the zero position as the center, and the corresponding perpendicularity deviation value is marked next to the concentric circle scale lines.

[0014] In one embodiment, the rigid frame includes an upper crossbeam, a lower crossbeam, a left vertical bar, and a right vertical bar connected to each other; the upper and lower crossbeams extend in a second direction, the left and right vertical bars extend in a first direction, and the second direction is perpendicular to the first direction. The open ring component is connected to the left or right vertical bar, the automatic leveling instrument is installed on the upper horizontal beam, and the scale is installed on the lower horizontal beam.

[0015] According to another aspect of this disclosure, a method for detecting the verticality of photovoltaic support column installation, employing a photovoltaic support column installation verticality detection device, includes the following steps: S100: Hold the open ring component on the outer periphery of the photovoltaic support column; S200: Automatic leveling instrument projects a laser line vertically downwards onto the dial; S300: Observe the projection position of the laser line on the dial and read the corresponding perpendicularity deviation value; S400: If the verticality deviation value exceeds the allowable range, correct the posture of the photovoltaic support column and repeat step S300 until the verticality deviation value meets the allowable range.

[0016] In one embodiment, the photovoltaic support column verticality detection method further includes the following steps before step S300: S510: The tilt sensor of the automatic level instrument detects the tilt angle of the photovoltaic support column; S520: The control module of the automatic level converts the tilt angle into the verticality of the column and compares it with a preset threshold. S530: When the verticality of the column is greater than the preset threshold, the control module controls the alarm unit to issue an alarm signal, then corrects the posture of the photovoltaic support column, repeats steps S510 and S520 until the verticality of the column is less than the preset threshold and the alarm unit stops alarming.

[0017] In the above embodiment, the open ring component is fixedly connected to the rigid frame, snaps into one side of the photovoltaic support column, and holds it to the outer circumference of the photovoltaic support column, so that the detection device tilts synchronously with the photovoltaic support column. An automatic level is installed on the upper part of the rigid frame and projects a laser line downwards in a vertical direction. A scale is installed on the lower part of the rigid frame and is arranged vertically and correspondingly to the automatic level, so that the laser line can illuminate the surface of the scale. When the photovoltaic support column is vertical, the laser line is projected to the zero position of the scale. When the photovoltaic support column tilts, the open ring component and the rigid frame tilt synchronously with the photovoltaic support column, while the laser line remains vertical. This allows the direction and distance of the laser line deviating from the zero position on the scale to intuitively reflect the tilt direction and degree of the photovoltaic support column. The deviation value of the verticality of the photovoltaic support column can be directly read through the dial, providing construction personnel with accurate quantitative test data. This allows construction personnel to make targeted and precise adjustments to the column based on the test data, controlling the verticality of the column within the specified range and ensuring the installation quality of the photovoltaic support column.

[0026] See Figure 1 This disclosure provides a photovoltaic support column verticality detection device, including: a rigid frame 10, an open ring member 20, an automatic level 30, and a dial 40. The open ring member 20 is connected to the rigid frame 10, and the opening of the open ring member 20 faces away from the rigid frame 10. The open ring member 20 is used to hold the outer peripheral surface of the photovoltaic support column, and the axial direction of the open ring member 20 is defined as a first direction. The automatic level 30 is installed on the upper part of the rigid frame 10 and is used to project a laser line downward in the vertical direction. The dial 40 is installed on the lower part of the rigid frame 10 and is arranged opposite to the automatic level 30 in the first direction. The dial 40 has scale lines for indicating verticality deviation. When the first direction is vertical, the laser line is projected to the zero position of the scale line.

[0027] The rigid frame 10 is a frame structure welded from square steel, serving as the basic load-bearing component of the entire testing device and providing stable installation support for each part.

[0028] The open-ring component 20 can be a semi-circular or arc-shaped component, which is fixedly connected to the rigid frame 10. The open-ring component 20 is used to snap into and hold the outer circumference of the photovoltaic support column from one side, so that the detection device as a whole is relatively fixed to the photovoltaic support column. When the semi-circular open-ring component 20 is held to the outer circumference of the photovoltaic support column, the construction personnel only need to manually support the open-ring component 20 to keep it in contact with the outer circumference of the photovoltaic support column to ensure the relative fixation of the detection device and the photovoltaic support column. There is no need to use bolts, clips or other additional locking parts, avoiding the indentation or scratches caused by locking parts to the surface of the photovoltaic support column.

[0029] When the open-ring component 20 is held against the outer circumferential surface of the photovoltaic support column, the axial direction of the open-ring component 20 is consistent with the axial direction of the photovoltaic support column. The photovoltaic support column is a cylindrical structural component with a cylindrical outer circumferential surface. Correspondingly, the inner circumferential surface of the open-ring component 20 is an arc surface adapted to the outer circumferential surface of the photovoltaic support column. When the open-ring component 20 is inserted from one side of the photovoltaic support column, the arc portion of its inner circumferential surface forms a surface contact with the outer circumferential surface of the photovoltaic support column, allowing the open-ring component 20 to be stably held against the outer circumferential surface of the photovoltaic support column without easy relative slippage. Because the inner circumferential surface of the open-ring component 20 is adapted to the outer circumferential surface of the photovoltaic support column, and the axial direction of the open-ring component 20 is consistent with the axial direction of the photovoltaic support column, it ensures that there is no directional deviation when the entire detection device tilts synchronously with the photovoltaic support column.

[0030] The automatic level 30 is equipped with a laser. When powered on, the laser emits a laser line that is projected vertically downwards onto the scale 40. The laser line can be projected vertically directly from the laser, or it can be projected from the laser in other directions and then converted by optical elements inside the automatic level 30 before being emitted vertically.

[0031] The automatic leveling instrument 30 and the scale 40 are arranged vertically to correspond to each other, so that the laser line 30a projected by the automatic leveling instrument 30 can illuminate the surface of the scale 40. When the photovoltaic support column is in a vertical state, the laser line is projected onto the zero position of the scale 40. When the photovoltaic support column is tilted, the axial direction of the open ring component 20 tilts synchronously with the photovoltaic support column, and the automatic leveling instrument 30, which is fixed on the rigid frame 10, tilts synchronously with the photovoltaic support column. However, the laser line 30a projected by the automatic leveling instrument 30 always remains vertical. Therefore, the projection position of the laser line 30a on the scale 40 will deviate from the zero position. The verticality deviation of the photovoltaic support column can be determined by reading the direction and distance of the laser line 30a deviating from the zero position.

[0032] In the above embodiment, the open ring component 20 is fixedly connected to the rigid frame 10, and is inserted from one side of the photovoltaic support column and held on the outer circumference of the photovoltaic support column, so that the detection device tilts synchronously with the photovoltaic support column. The automatic level 30 is installed on the upper part of the rigid frame 10 and projects a laser line 30a vertically downward. The scale 40 is installed on the lower part of the rigid frame 10 and is arranged vertically and vertically corresponding to the automatic level 30, so that the laser line can illuminate the surface of the scale 40. When the photovoltaic support column is in a vertical state, the laser line is projected to the zero position of the scale 40. When the photovoltaic support column is tilted, the open ring component 20 and the rigid frame 10 tilt synchronously with the photovoltaic support column, while the laser line always remains vertical, so that the direction and distance of the laser line deviating from the zero position on the scale 40 can intuitively reflect the tilt direction and degree of the photovoltaic support column. The deviation value of the verticality of the photovoltaic support column can be directly read through the dial 40, providing construction personnel with accurate quantitative test data. This allows construction personnel to make targeted and precise adjustments to the column based on the test data, controlling the verticality of the column within the specified range and ensuring the installation quality of the photovoltaic support column.

[0033] The automatic leveling instrument 30 is equipped with a gravity compensator. When the rigid frame 10 tilts with the column, the gravity compensator automatically adjusts the internal optical path using gravity, ensuring that the laser line projected by the automatic leveling instrument 30 remains vertical and unaffected by the tilt of the rigid frame 10. This guarantees that the projection position of the laser line on the scale 40 reflects the tilt state of the column. The gravity compensator includes a sensitive element, a compensating element, and a damping system. The sensitive element senses the tilt direction and degree of the instrument under gravity. The compensating element makes corresponding displacement or deflection based on the sensing result of the sensitive element to correct the optical path. The damping system absorbs the vibration of the compensating element, allowing it to quickly stabilize. When the rigid frame 10 tilts along with the photovoltaic support column, the automatic level 30 installed on the upper part of the rigid frame 10 tilts accordingly. The sensitive element in the gravity compensator then senses the tilt and drives the compensating element to move. The compensating element corrects the optical path of the laser to keep the laser line vertical, thereby ensuring that the projection position of the laser line on the scale 40 depends only on the tilt of the column and is independent of the tilt posture of the rigid frame 10 itself, thus ensuring the accuracy and consistency of the measurement results under different installation postures.

[0034] The specific structure of the automatic leveling instrument 30 can be referenced from existing technologies, and will not be elaborated further.

[0035] In one embodiment, the scale lines are concentric circle scale lines with the zero position as the center, and the corresponding perpendicularity deviation value is marked next to the concentric circle scale lines.

[0036] The aforementioned concentric circle scale lines include multiple circular scale lines with different radii. Each circular scale line is arranged radially from the center of the scale dial 40 as the zero point. The radius of each concentric circle scale line corresponds to a different verticality deviation value. That is, the greater the distance of the laser line's projection position on the scale dial 40 from the zero point, the greater the corresponding verticality deviation value. The corresponding verticality deviation value is marked next to each concentric circle scale line. The marking method can be printing or etching the value directly on one end or above the scale line. When reading the laser line projection position, the construction personnel first observe which concentric circle scale line the laser line falls on, and then directly read the verticality deviation value marked next to that scale line to obtain the current verticality deviation of the photovoltaic support column without any additional conversion or calculation.

[0037] In the above embodiment, the concentric circle scale lines on the dial 40 establish a correspondence between the distance of the laser line from the zero position and the verticality deviation of the column. With the deviation values ​​marked next to each scale line, construction personnel can directly read the verticality deviation value while observing the laser line projection position, without the need for conversion or calculation. This simplifies the reading steps, improves detection efficiency, and avoids reading errors caused by manual conversion.

[0038] See Figure 1 In one embodiment, the rigid frame 10 includes an upper crossbeam 11, a lower crossbeam 12, a left vertical bar 13, and a right vertical bar 14 connected to each other. The upper crossbeam 11 and the lower crossbeam 12 extend in a second direction, while the left vertical bar 13 and the right vertical bar 14 extend in a first direction, with the second direction perpendicular to the first direction. An open ring member 20 is connected to either the left vertical bar 13 or the right vertical bar 14. An automatic leveling instrument 30 is mounted on the upper crossbeam 11, and a scale dial 40 is mounted on the lower crossbeam 12.

[0039] The upper crossbeam 11, lower crossbeam 12, left vertical rod 13, and right vertical rod 14 are all made of square steel and are welded together to form a rectangular rigid frame 10. The automatic leveling instrument 30 is installed at the center of the upper crossbeam 11 by bolts or other means, and the scale dial 40 is installed at the center of the lower crossbeam 12 by bolts or other means, so that the automatic leveling instrument 30 and the scale dial 40 are arranged vertically and vertically in a first direction. The automatic leveling instrument 30 and the scale dial 40 do not necessarily have to be located at the center of the upper crossbeam 11 and lower crossbeam 12, as long as they are aligned along the first direction.

[0040] In the above embodiment, the rigid frame 10 adopts a rectangular frame structure formed by the upper crossbeam 11, the lower crossbeam 12, the left vertical bar 13 and the right vertical bar 14. The automatic leveling instrument 30 is installed on the upper crossbeam 11 and the scale 40 is installed on the lower crossbeam 12. The two are arranged vertically and vertically along the first direction to ensure that the laser line can be accurately projected onto the surface of the scale 40. When the column is in a vertical state, the laser line falls exactly at the zero position of the scale 40, realizing precise control of the laser projection position.

[0041] See Figure 1 In one embodiment, the open ring member 20 includes an upper open ring member 21 and a lower open ring member 22. The upper open ring member 21 and the lower open ring member 22 are disposed on the same side of the rigid frame 10 along a second direction, which is perpendicular to the first direction. The axis of the upper open ring member 21 coincides with the axis of the lower open ring member 22.

[0042] For example, both the upper open-ring member 21 and the lower open-ring member 22 are fixedly connected to the left vertical rod 13, with the upper open-ring member 21 located at the upper part of the left vertical rod 13 and the lower open-ring member 22 located at the lower part of the left vertical rod 13, and the two are arranged at intervals along the first direction. The openings of both the upper open-ring member 21 and the lower open-ring member 22 face away from the rigid frame 10.

[0043] In the above embodiments, the upper open ring component 21 and the lower open ring component 22 are arranged at intervals along the first direction and their axes coincide. Both are set on the same side of the rigid frame 10 along the second direction, so that the detection device and the photovoltaic support column form two fixed points distributed along the first direction. This can limit the rigid frame 10 from tilting relative to the photovoltaic support column, ensure the relative posture stability between the rigid frame 10 and the photovoltaic support column, and avoid measurement errors caused by the swing of the detection device relative to the photovoltaic support column. At the same time, the openings of the upper open ring component 21 and the lower open ring component 22 are in the same direction, which makes it easy to insert from one side of the photovoltaic support column without having to put it on from the top of the photovoltaic support column, making the operation convenient and quick.

[0044] In one embodiment, the photovoltaic support column verticality detection device further includes a spirit level, which is installed on the rigid frame 10 and used to determine the verticality of the photovoltaic support column.

[0045] The spirit level is a bubble-type level indicator. It contains liquid and an air bubble, and the position of the bubble within the liquid indicates whether the column is level. The spirit level can be installed on the top of the upper crossbeam 11 of the rigid frame 10 or at the top of the left vertical bar 13 or the right vertical bar 14 for easy observation by construction personnel. After the open ring component 20 is positioned around the outer surface of the photovoltaic support column, construction personnel can initially determine the verticality of the photovoltaic support column by observing the position of the bubble in the spirit level. If the bubble is centered, it indicates that the photovoltaic support column is basically vertical; if the bubble is off-center, it indicates that the photovoltaic support column is tilted to that side. Construction personnel can adjust the posture of the photovoltaic support column based on the spirit level's indication to make it roughly vertical before proceeding with subsequent measurements.

[0046] In the above embodiment, the spirit level is installed on the rigid frame 10. After the construction personnel hold the open ring component 20 on the outer circumference of the column, they can quickly determine whether the column is roughly vertical by observing the position of the bubble in the spirit level. This makes it easier to screen out obviously tilted columns in the early stage of detection, avoid directly performing invalid laser measurements, and improve detection efficiency.

[0047] In one embodiment, the photovoltaic support column verticality detection device includes multiple open ring components 20 with different inner diameters. The rigid frame 10 can be detachably connected to any one of the multiple open ring components 20 with different inner diameters.

[0048] Different inner diameter open-ring components 20 are used to adapt to photovoltaic support columns with different outer diameters. The rigid frame 10 can be detachably connected to any of the various open-ring components 20 with different inner diameters. The detachable connection can be achieved by bolt connection, pin connection, or snap-fit ​​connection. At the construction site, the construction personnel select an open-ring component 20 with an inner diameter that matches the actual outer diameter of the photovoltaic support column to be tested, and fix the selected open-ring component 20 to the left vertical bar 13 or right vertical bar 14 of the rigid frame 10 using bolts or pins, thus completing the assembly of the testing device. When it is necessary to test photovoltaic support columns with different diameter specifications, simply remove the installed open-ring component 20 from the rigid frame 10 and replace it with another open-ring component 20 with an inner diameter that matches the photovoltaic support column to be tested.

[0049] When replacing the open ring component 20, the open ring component 20 is detachably connected to the rigid frame 10 through bolts or pins and other connecting parts to meet the adaptation requirements of columns of different diameters. After replacement, when the open ring component 20 is held on the outer circumference of the column during the inspection process, the construction personnel only need to manually support the open ring component 20 to keep it in contact with the outer circumference of the column to ensure the relative fixation of the device and the column.

[0050] In the above embodiments, construction personnel select an open-ring component 20 with an inner diameter that matches the actual outer diameter of the photovoltaic support column to be tested and install it on the rigid frame 10. This allows the same rigid frame 10 to be used for verticality testing of photovoltaic support columns with various diameters, eliminating the need to equip each photovoltaic support column with a complete testing device, thus reducing equipment costs and the complexity of on-site management. Furthermore, replacing the open-ring component 20 only requires disassembling and assembling the connecting parts, making the operation simple and quick, and improving the versatility and on-site adaptability of the testing device.

[0051] In one embodiment, the automatic leveling instrument 30 further includes: a tilt sensor, an alarm unit, and a control module. The tilt sensor is used to detect the tilt angle of the photovoltaic support column. The control module stores a preset threshold. When the verticality of the photovoltaic support column calculated from the tilt angle detected by the tilt sensor is greater than the preset threshold, the control module controls the alarm unit to issue an alarm signal.

[0052] The tilt sensor is used to detect the tilt angle of the laser automatic level 30, and can be implemented using existing angle detection elements such as MEMS accelerometers or electrolyte pendulum sensors. The alarm unit is used to issue alarm signals, and can be implemented using existing audible and visual alarm devices such as buzzers, speakers, or LED indicators. The control module is used to receive the detection signal from the tilt sensor, convert the tilt angle into column verticality and compare it with a preset threshold, and send a trigger signal to the alarm unit when the threshold is exceeded; it can be implemented using a microcontroller (MCU).

[0053] The tilt sensor, alarm unit, and control module are all integrated inside the automatic level 30. The tilt sensor is used to detect the tilt angle of the automatic level 30. Since the automatic level 30 is fixedly installed on the rigid frame 10, and the rigid frame 10 is held to the outer circumference of the photovoltaic support column by the open ring member 20, the tilt angle detected by the tilt sensor reflects the tilt angle of the photovoltaic support column.

[0054] The control module is electrically connected to both the tilt sensor and the alarm unit, and stores preset thresholds. The tilt sensor detects the tilt angle of the photovoltaic support column in real time and transmits the detected tilt angle signal to the control module. The control module converts the received tilt angle into the verticality of the photovoltaic support column and compares it with the preset thresholds stored internally.

[0055] When the verticality of the photovoltaic support column exceeds a preset threshold, the control module determines that the verticality of the photovoltaic support column exceeds the standard and sends a trigger signal to the alarm unit. Upon receiving the trigger signal, the alarm unit issues an alarm signal. The alarm signal can be an audible alarm, a flashing alarm, or a combination of audible and visual alarms. The preset threshold can be set and adjusted according to construction specifications, for example, set to 3%.

[0056] In the above embodiments, the tilt sensor, alarm unit, and control module are integrated into the automatic level instrument 30. The detection device not only completes the verticality detection of the photovoltaic support column, but also has automatic monitoring and early warning functions. The tilt sensor detects the tilt angle of the photovoltaic support column in real time, and the control module converts the tilt angle into the verticality of the photovoltaic support column and compares it with a preset threshold. The verticality of the photovoltaic support column can be monitored without continuous manual observation. When the verticality of the photovoltaic support column exceeds the standard, the alarm unit automatically sends an alarm signal to remind the construction personnel to make corrections, so that the verticality deviation during the construction process can be detected and corrected in a timely manner, effectively ensuring the installation quality of the photovoltaic support column.

[0057] In one embodiment, the scale range of the dial 40 corresponds to a preset threshold. When the verticality of the photovoltaic support column is greater than the preset threshold, the laser line is projected outside the scale range of the dial 40, and the alarm unit emits an alarm signal. When the verticality of the photovoltaic support column is less than the preset threshold, the laser line is projected within the scale range of the dial 40 to indicate the verticality deviation value.

[0058] The dial 40 has concentric circular scale lines centered at the zero position. The area enclosed by the outermost concentric scale lines is the scale range of the dial 40, and the maximum perpendicularity deviation value corresponding to this scale range is equal to a preset threshold. In this application, "outside the scale range" refers to the area beyond the outermost scale lines on the dial 40, including the blank area at the edge of the dial 40 and the area outside the dial 40.

[0059] When the verticality of the photovoltaic support column exceeds the preset threshold, the projection position of the laser line on the dial 40 exceeds the area enclosed by the outermost scale line. That is, the laser line is projected outside the scale range of the dial 40. At this time, there is no corresponding scale line on the dial 40 for the laser line to be read. The construction personnel cannot obtain a valid verticality deviation value through the dial 40. They need to know that the verticality of the column has exceeded the standard through the alarm signal of the alarm unit and make corrections.

[0060] When the verticality of the photovoltaic support column is less than the preset threshold, the laser line is projected within the scale range of the dial 40, and the construction personnel can directly read the corresponding deviation value for precise measurement. In this way, the upper limit of the measuring range of the dial 40 is consistent with the preset threshold. When the range is exceeded, an alarm is triggered; when the range is within the range, the reading is obtained from the dial.

[0061] In the above embodiment, the scale range of the dial 40 corresponds to a preset threshold. When the column's verticality exceeds the preset threshold, the laser line extends beyond the scale range of the dial 40 and cannot be read from it. The alarm unit issues an alarm signal, which the construction personnel use for correction. In this case, the alarm signal serves as a coarse measurement. When the column's verticality is not greater than the preset threshold, the laser line falls within the scale range of the dial 40. The construction personnel obtain the specific verticality deviation value by reading the projection position of the laser line on the dial 40. In this case, the laser, in conjunction with the dial, performs a fine measurement. That is, when the verticality exceeds the preset threshold, an alarm signal is used for coarse measurement; when the verticality is not greater than the preset threshold, the laser, in conjunction with the dial, performs a fine measurement. This allows the detection process to progress step by step from coarse to fine measurement, gradually improving the detection precision and preventing construction personnel from attempting to read invalid values ​​when the verticality exceeds the limit. This improves the efficiency and reliability of the entire detection process.

[0062] In this disclosure, the spirit level, tilt sensor, and dial 40 correspond to three different accuracy levels in the detection process. The spirit level is mounted on the rigid frame 10. After the operator holds the column on the outer circumference with the open ring component 20, they observe the position of the bubble in the spirit level to determine if the column is roughly vertical, achieving the lowest accuracy preliminary judgment and coarse adjustment. The tilt sensor detects the tilt angle of the column in real time and converts it into column verticality by the control module. When this verticality exceeds a preset threshold, the control module controls the alarm unit to issue an alarm signal. The operator corrects according to the alarm prompt until the alarm stops, achieving medium accuracy numerical detection and judgment. After the alarm stops, the automatic leveling instrument 30 projects a laser line onto the dial 40. The operator obtains the specific verticality deviation value by reading the projection position of the laser line on the dial 40, achieving the highest accuracy quantitative reading. The three levels of accuracy increase sequentially, corresponding to different detection requirements, making the entire detection process progressively from coarse to fine.

[0063] In one embodiment, the dial 40 is a transparent plate, such as a transparent acrylic plate. A laser line is projected from the automatic leveling instrument 30 onto the surface of the dial 40. The operator can observe the projection position of the laser line from the front of the dial 40, and simultaneously observe the transmission position of the laser line from the back of the dial 40, facilitating reading under different lighting conditions. The transparent plate material also facilitates the processing of scale lines on the dial 40; scale lines can be formed on the surface of the transparent plate using laser engraving or printing methods.

[0064] See Figure 2 This disclosure also provides a method for detecting the verticality of photovoltaic support column installation, using a photovoltaic support column installation verticality detection device. The method includes the following steps: S100: Hold the open ring component 20 on the outer periphery of the photovoltaic support column.

[0065] Specifically, the construction worker holds the rigid frame 10 and inserts the open ring component 20 from one side of the photovoltaic support column, so that the inner circumferential surface of the open ring component 20 fits against the outer circumferential surface of the photovoltaic support column. The construction worker can manually support the open ring component 20 to ensure the relative fixation of the detection device and the photovoltaic support column.

[0066] S200: Automatic leveling instrument 30 projects a laser line vertically downwards onto the dial 40.

[0067] After the automatic leveling instrument 30 is powered on, its internal laser emits a laser line, which shines vertically downwards onto the dial surface 40.

[0068] S300: Observe the projection position of the laser line on the dial 40 and read the corresponding perpendicularity deviation value.

[0069] Construction workers visually observe the position of the laser line on the dial 40, determine the direction and distance of deviation between the laser line and the zero position of the dial 40, and read the corresponding verticality deviation value.

[0070] S400: If the verticality deviation value exceeds the allowable range, correct the posture of the photovoltaic support column and repeat step S300 until the verticality deviation value meets the allowable range.

[0071] If the distance of the laser line deviating from the zero position exceeds the allowable range, it indicates that the verticality of the photovoltaic support column does not meet the requirements. The construction personnel will correct the posture of the photovoltaic support column, and after correction, observe the projection position of the laser line on the scale 40 again and read the deviation value. This process will be repeated until the projection position of the laser line on the scale 40 meets the allowable range.

[0072] In the above embodiment, the detection device is tilted synchronously with the photovoltaic support column by the open ring component 20 holding it on the outer circumference of the photovoltaic support column. The direction and distance of the laser line projected by the automatic level 30 on the scale 40 from the zero position reflect the tilt direction and degree of the photovoltaic support column. Construction personnel can intuitively read the corresponding verticality deviation value by observing the projection position of the laser line on the scale 40, realizing the quantitative detection of the verticality of the photovoltaic support column. When the deviation value exceeds the allowable range, the construction personnel correct the posture of the photovoltaic support column according to the reading of the scale 40 and then reproject and read, forming a closed-loop correction process, so that the verticality of the photovoltaic support column can finally meet the allowable range, ensuring the construction quality of the photovoltaic support column installation.

[0073] In one embodiment, the detection method described above further includes the following step before step S300: S510: The tilt sensor of the automatic level instrument 30 detects the tilt angle of the photovoltaic support column.

[0074] S520: The control module of the automatic level instrument 30 converts the tilt angle into the verticality of the photovoltaic support column and compares it with the preset threshold.

[0075] S530: When the verticality of the photovoltaic support column is greater than the preset threshold, the control module controls the alarm unit to issue an alarm signal, then corrects the posture of the photovoltaic support column, repeats steps S510 and S520, until the verticality of the photovoltaic support column is less than the preset threshold and the alarm unit stops alarming.

[0076] In the above embodiments, after the tilt sensor detects the tilt angle of the column, the control module converts it into the column verticality and compares it with a preset threshold. The control module automatically determines whether the column verticality exceeds the standard, realizing a rapid coarse measurement of the column verticality. When it exceeds the standard, the alarm unit issues an alarm signal, and the construction personnel correct it according to the alarm prompt. During the correction process, the tilt sensor continuously detects and the control module continuously compares until the column verticality reaches the standard and the alarm stops, forming a closed-loop correction process. This ensures that the column is basically vertical when entering the fine measurement stage, avoiding the problem of the laser line not falling into the effective range of the scale and thus being unable to read the value when the value exceeds the standard by directly projecting a laser for fine measurement. This ensures that the subsequent fine measurement steps can be carried out effectively, and the detection process progresses from coarse measurement judgment to fine measurement reading, improving detection efficiency.

[0077] In addition, when the value exceeds the preset threshold, an alarm signal is used to make a coarse judgment, and when the value does not exceed the preset threshold, a laser combined with a dial is used to make a fine reading. This allows the detection process to progress step by step from coarse to fine, and the detection precision is gradually improved. This avoids construction personnel trying to read invalid values ​​when the value exceeds the limit, and improves the efficiency and reliability of the entire detection process.

[0078] It should be noted that although the steps of the detection method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that these steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.
