Description

Technical Field

[0001] This invention relates to the field of angle measuring device technology, and in particular to a measuring device for photovoltaic brackets. Background Technology

[0002] In the current context of the rapid development of the solar photovoltaic industry, the accuracy of photovoltaic panel installation directly affects power generation efficiency and system stability. Traditional photovoltaic support system installation presents numerous challenges in measuring verticality and photovoltaic panel tilt. Some measurement methods rely on manual methods using tools such as tape measures and levels, which are not only cumbersome and inefficient but also prone to human error and insufficient tool precision. This can lead to deviations in photovoltaic support verticality and photovoltaic panel tilt angles that do not meet design requirements, thereby reducing the power generation efficiency of the photovoltaic system. Furthermore, existing measuring devices often have limited functionality and cannot simultaneously measure both support verticality and photovoltaic panel tilt, necessitating multiple measurements and repeated adjustments during installation, significantly increasing construction and time costs. Summary of the Invention

[0003] This invention provides a measuring device for photovoltaic brackets to solve the problem of limited measurement functions in existing devices.

[0004] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0005] A measuring device for a photovoltaic bracket includes a clamping mechanism, on which a vertical measuring mechanism and an inclined measuring mechanism are connected, and the clamping mechanism is connected to the photovoltaic bracket.

[0006] The vertical measuring mechanism includes a horizontal bar with a measuring rod hinged to its end. The horizontal bar can slide toward the photovoltaic bracket so that the measuring rod fits against the photovoltaic bracket. When the horizontal bar is perpendicular to the measuring rod, the photovoltaic bracket is in a vertical state.

[0007] The tilt measuring mechanism includes a mounting plate with two vertical rods symmetrically slidably connected on it. The mounting plate is positioned on the upper part of the photovoltaic panel. After the two vertical rods fall and contact the photovoltaic panel, the falling distance and radial distance of the two vertical rods are obtained, thereby determining the tilt of the photovoltaic panel.

[0008] Furthermore, the clamping mechanism includes a U-shaped block with a screw threaded onto it. A clamping plate is rotatably connected to the end of the screw, and when the screw is tightened, the clamping plate can abut against the photovoltaic bracket.

[0009] Furthermore, it also includes a calibration mechanism, which includes a cylinder fixedly connected to the U-shaped block, a rotating rod rotatably connected inside the cylinder, an installation rod fixedly connected to the end of the rotating rod, a tilt measuring mechanism connected to the top of the installation rod, and a counterweight fixedly connected to the bottom of the installation rod.

[0010] Furthermore, the correction mechanism also includes an electric telescopic rod fixedly connected to the U-shaped block. The output end of the electric telescopic rod is fixedly connected to a straight telescopic rod, and the end of the straight telescopic rod is fixedly connected to a locking block. The cylinder has a hole that mates with the locking block. A first spring is sleeved on the straight telescopic rod, and the two ends of the first spring are respectively connected to the electric telescopic rod and the locking block. When the electric telescopic rod extends, the locking block can abut against the rotating rod to lock the mounting rod.

[0011] Furthermore, the vertical measuring mechanism also includes a mounting bracket fixedly connected to the mounting rod, a locking pin slidably connected to the mounting bracket, and an insertion hole that mates with the locking pin on the horizontal rod;

[0012] A first tension spring is connected between the pin cap of the locking pin and the mounting bracket, and a pull rope is connected between the locking pin and the output end of the electric telescopic rod. When the electric telescopic rod extends to lock the mounting rod, the electric telescopic rod pulls the pull rope and lifts the locking pin away from the horizontal rod.

[0013] Furthermore, a guide rod is fixedly connected to the mounting bracket, a through hole is provided on the horizontal rod to cooperate with the guide rod, and a second tension spring is connected between the horizontal rod and the mounting bracket.

[0014] Furthermore, a rotating shaft is fixedly connected to the middle of the measuring rod, and the rotating shaft is rotatably connected to the end of the horizontal rod. An angle sensor for detecting the rotation angle of the rotating shaft is connected to the horizontal rod.

[0015] Furthermore, the tilt measuring mechanism also includes a mounting base connected to the top of the mounting rod. A cylindrical rod is fixedly connected to the middle of the mounting plate. The cylindrical rod is rotatably connected to the mounting base. A rectangular tube is fixedly connected to the top of the cylindrical rod. Two limiting rods are symmetrically slidably connected inside the rectangular tube. The two limiting rods can move closer to or further away from the two vertical rods, thereby locking or unlocking the vertical rods to the mounting plate.

[0016] Furthermore, the mounting plate is provided with two displacement sensors for detecting the sliding distance between the two mounting plates.

[0017] Furthermore, a piston cylinder is fixedly connected to the mounting bracket, and an air pipe connects the piston cylinder and the rectangular cylinder. A piston rod is slidably connected inside the piston cylinder, and a connecting bracket is fixedly connected to the end of the piston rod. The connecting bracket is fixedly connected to the pull rope. When the pull rope pulls the locking pin, the piston rod can slide, thereby drawing gas from the rectangular cylinder to unlock the vertical rod.

[0018] The beneficial effects of this invention are analyzed as follows:

[0019] A measuring device for a photovoltaic (PV) mounting bracket includes a clamping mechanism with a vertical measuring mechanism and an inclined measuring mechanism connected to it. The clamping mechanism is connected to the PV mounting bracket. The vertical measuring mechanism includes a horizontal rod with a measuring rod hinged to its end. The horizontal rod can slide towards the PV mounting bracket so that the measuring rod fits against the PV mounting bracket. When the horizontal rod is perpendicular to the measuring rod, the PV mounting bracket is in a vertical state. The inclined measuring mechanism includes a mounting plate with two vertical rods symmetrically slidably connected to it. The mounting plate is positioned on the upper part of the PV panel. After the two vertical rods fall and contact the PV panel, the falling distance and radial distance of the two vertical rods are obtained, thereby determining the inclination of the PV panel.

[0020] When testing the verticality of a photovoltaic (PV) mounting bracket, the horizontal bar is brought closer to the bracket, maintaining a horizontal position. The measuring rod is perpendicular to the horizontal bar. After the horizontal bar is brought close to the bracket, ensuring the measuring rod remains perpendicular to the bracket, the PV bracket is considered vertically installed. When measuring the tilt of the PV panel, the direction of the line connecting the centers of the two vertical bars is aligned with the tilt direction of the PV panel. The two vertical bars are then released, ensuring their bottom ends contact the PV panel surface, and the distance between the axes of the two vertical bars is pre-defined. Knowing and determining the downward distance of the two vertical rods, the tilt of the photovoltaic panel can be obtained. The specific calculation formula is: tilt θ = arctan(L / d), where L is the height difference between the bottom ends of the two vertical rods in the tilt direction (i.e., the opposite side of the right triangle), and d is the horizontal projection distance of the line connecting the centers of the two vertical rods (i.e., the adjacent side of the right triangle). Through this measuring device, the verticality of the photovoltaic support and the tilt of the photovoltaic panel can be accurately and quickly detected, which provides convenience for the installation of photovoltaic panels and improves the accuracy of photovoltaic panel installation.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figures 1-7 As shown, a measuring device for a photovoltaic (PV) bracket includes a clamping mechanism 100, on which a vertical measuring mechanism 300 and an inclined measuring mechanism 400 are connected. The clamping mechanism 100 is connected to the PV bracket. The vertical measuring mechanism 300 includes a horizontal rod 320, with a measuring rod 321 hinged to the end of the horizontal rod 320. The horizontal rod 320 can slide toward the PV bracket so that the measuring rod 321 fits against the PV bracket. When the horizontal rod 320 is perpendicular to the measuring rod 321, the PV bracket is in a vertical state. The inclined measuring mechanism 400 includes a mounting plate 420, on which two vertical rods 450 are symmetrically slidably connected. The mounting plate 420 is disposed on the upper part of the PV panel. After the two vertical rods 450 fall and contact the PV panel, the falling distance and radial distance of the two vertical rods 450 are obtained, thereby determining the inclination of the PV panel.

[0035] The working mechanism of the measuring device provided in this embodiment:

[0036] In use, the device is fixed to the photovoltaic panel bracket by the clamping mechanism 100. The vertical measuring mechanism 300 detects the verticality of the photovoltaic panel, and the tilt measuring mechanism 400 detects the tilt of the photovoltaic panel after installation. When detecting the verticality of the photovoltaic bracket, the horizontal rod 320 moves closer to the photovoltaic bracket and is in a horizontal state. The measuring rod 321 is perpendicular to the horizontal rod 320. Thus, the horizontal rod 320 moves closer to the photovoltaic bracket in a horizontal state so that the measuring rod 321 is in contact with the photovoltaic bracket. If the measuring rod 321 and the horizontal rod 320 are still in a vertical state, it means that the photovoltaic bracket is installed vertically.

[0037] When measuring the tilt of a photovoltaic panel, the direction of the line connecting the centers of the two vertical rods 450 is aligned with the tilt direction of the photovoltaic panel. The two vertical rods 450 are then released so that their bottom ends contact the surface of the photovoltaic panel. The distance between the axes of the two vertical rods 450 is known and definite. By measuring the downward distance of the two vertical rods 450, the tilt of the photovoltaic panel can be determined. The specific calculation formula is: tilt θ = arctan(L / d), where L is the height difference between the bottom ends of the two vertical rods 450 in the tilt direction (i.e., the opposite side of the right triangle), and d is the horizontal projection distance of the line connecting the centers of the two vertical rods 450 (i.e., the adjacent side of the right triangle). This measuring device can accurately and quickly detect the verticality of the photovoltaic support and the tilt of the photovoltaic panel, facilitating the installation of the photovoltaic panel and improving its accuracy.

[0038] Regarding the structure of the clamping mechanism 100, specifically:

[0039] The clamping mechanism 100 includes a U-shaped block 110, on which a screw 130 is threadedly connected. A clamping plate 120 is rotatably connected to the end of the screw 130. When the screw 130 is tightened, the clamping plate 120 can abut against the photovoltaic bracket.

[0040] Insert the U-shaped block 110 into the photovoltaic bracket, tighten the screw 130, and ensure that the clamp 120 is tightly attached to the bracket to ensure the stability of the device.

[0041] Regarding the structure of the correction mechanism 200, specifically:

[0042] The calibration mechanism 200 includes a cylinder 230 fixedly connected to the U-shaped block 110, a rotating rod 220 rotatably connected inside the cylinder 230, an installation rod 210 fixedly connected to the end of the rotating rod 220, an inclination measuring mechanism 400 connected to the top of the installation rod 210, and a counterweight 270 fixedly connected to the bottom of the installation rod 210.

[0043] When the rotating rod 220 is not locked to the cylinder 230, it can rotate freely, so that the gravity of the counterweight 270 can keep the mounting rod 210 in a vertical state and the horizontal rod 320 in a horizontal state, thus ensuring measurement accuracy.

[0044] Among the optional methods in this embodiment, the more preferred one is:

[0045] The calibration mechanism 200 also includes an electric telescopic rod 240 fixedly connected to the U-shaped block 110. The output end of the electric telescopic rod 240 is fixedly connected to a straight telescopic rod 250, and the end of the straight telescopic rod 250 is fixedly connected to a locking block 260. The cylinder 230 has a hole that mates with the locking block 260. A first spring 251 is sleeved on the straight telescopic rod 250. The two ends of the first spring 251 are respectively connected to the electric telescopic rod 240 and the locking block 260. When the electric telescopic rod 240 extends, the locking block 260 can abut against the rotating rod 220 to lock the mounting rod 210.

[0046] After the mounting rod 210 is in a vertical position, the electric telescopic rod 240 is extended, causing the straight telescopic rod 250 to push the locking block 260 into the hole of the cylinder 230, so that the locking block 260 abuts against the side wall of the rotating rod 220, thereby locking the rotating rod 220 and ensuring that the mounting rod 210 remains vertical, further improving the measurement stability and accuracy. Due to the setting of the straight telescopic rod 250 and the first spring 251, it is ensured that the electric telescopic rod 240 can continue to extend after the locking block 260 abuts against the rotating rod 220, ensuring that after the subsequent extension of the electric telescopic rod 240 locks the mounting rod 210, it can continue to extend so that the subsequent locking pin 340 can be driven.

[0047] Among the optional methods in this embodiment, the more preferred one is:

[0048] The vertical measuring mechanism 300 also includes a mounting bracket 310 fixedly connected to the mounting rod 210. A locking pin 340 is slidably connected to the mounting bracket 310. A socket for the locking pin 340 is provided on the horizontal rod 320. A first tension spring 341 is connected between the pin cap of the locking pin 340 and the mounting bracket 310, and a pull rope 350 is connected between the locking pin 340 and the output end of the electric telescopic rod 240. When the electric telescopic rod 240 extends so that the mounting rod 210 is locked, the electric telescopic rod 240 pulls the pull rope 350 and lifts the locking pin 340 away from the horizontal rod 320.

[0049] After the electric telescopic rod 240 extends and the mounting rod 210 is locked, the electric telescopic rod 240 continues to extend, thereby the electric telescopic rod 240 further pulls the locking pin 340 through the pull rope 350, so that the locking pin 340 overcomes the elastic force of the first tension spring 341 and pulls out of the insertion hole of the horizontal rod 320. At this time, the horizontal rod 320 is unlocked, so that the horizontal rod 320 can move closer to the photovoltaic panel.

[0050] The mounting bracket 310 is also rotatably connected to two guide wheels 351, which guide the pull rope 350 so that the pull rope 350 is Z-shaped, thereby changing the transmission force applied by the electric telescopic rod 240 to the locking pin 340.

[0051] Among the optional methods in this embodiment, the more preferred one is:

[0052] A guide rod 330 is fixedly connected to the mounting bracket 310. A through hole is provided on the horizontal rod 320 to cooperate with the guide rod 330, and a second tension spring 331 is connected between the horizontal rod 320 and the mounting bracket 310.

[0053] The guide rod 330 guides the movement of the horizontal rod 320, ensuring that the horizontal rod 320 slides smoothly along the guide rod 330. Thus, after the locking pin 340 is pulled out of the socket, the horizontal rod 320 moves closer to the photovoltaic bracket under the action of the second tension spring 331 to perform the verticality measurement operation of the photovoltaic bracket.

[0054] Among the optional methods in this embodiment, the more preferred one is:

[0055] A rotating shaft 322 is fixedly connected to the middle of the measuring rod 321. The rotating shaft 322 is rotatably connected to the end of the horizontal rod 320. An angle sensor for detecting the rotation angle of the rotating shaft 322 is connected to the horizontal rod 320.

[0056] When the horizontal bar 320 is in its initial position, the measuring rod 321 is attached to the mounting bracket 310, and the angle sensor obtains the initial angle value of the rotating shaft 322 at this time. When the horizontal bar 320 moves closer to the photovoltaic bracket so that the measuring rod 321 is attached to the photovoltaic bracket, the angle sensor detects the angle value again. The verticality of the photovoltaic bracket is obtained by comparing the difference between the initial angle value and the detected angle value. That is, when the difference is zero, the photovoltaic bracket is vertical, and otherwise the photovoltaic bracket is tilted.

[0057] Among the optional methods in this embodiment, the more preferred one is:

[0058] The tilt measuring mechanism 400 also includes a mounting base 410 connected to the top of the mounting rod 210. A cylindrical rod 421 is fixedly connected to the middle of the mounting plate 420. The cylindrical rod 421 is rotatably connected to the mounting base 410. A rectangular tube 430 is fixedly connected to the top of the cylindrical rod 421. Two limiting rods 440 are symmetrically slidably connected inside the rectangular tube 430. The two limiting rods 440 can approach or move away from the two vertical rods 450, thereby locking or unlocking the vertical rods 450 to the mounting plate 420.

[0059] When measuring the tilt of the photovoltaic panel, the two limit rods 440 are brought closer together. At this time, the two vertical rods 450 are unlocked and can slide down under gravity until they contact the photovoltaic panel. The tilt of the photovoltaic panel is accurately calculated by the sliding distance of the vertical rods 450 to ensure the accuracy of the measurement results.

[0060] Among the optional methods in this embodiment, the more preferred one is:

[0061] The mounting plate 420 is equipped with two displacement sensors for detecting the sliding distance between the two mounting plates 420.

[0062] Reference Figure 6Two displacement sensors acquire sliding displacement data of the two vertical rods 450 respectively. After the control system acquires the sliding displacement data of the two vertical rods 450, it calculates the tilt of the photovoltaic panel according to the formula tilt θ=arctan(L / d).

[0063] Reference Figure 7 Change the direction of the line connecting the axes of the two vertical rods 450 to be perpendicular to the tilt direction of the photovoltaic panel, and release the two vertical rods 450 to contact the photovoltaic panel. If the difference in position distance between the two vertical rods 450 is zero, it means that the height of the photovoltaic brackets on both sides of the tilt direction of the photovoltaic panel is the same; otherwise, they are not the same.

[0064] Among the optional methods in this embodiment, the more preferred one is:

[0065] A piston cylinder 470 is fixedly connected to the mounting bracket 310. An air pipe 460 connects the piston cylinder 470 and the rectangular cylinder 430. A piston rod 480 is slidably connected inside the piston cylinder 470. A connecting bracket 481 is fixedly connected to the end of the piston rod 480. The connecting bracket 481 is fixedly connected to the pull rope 350. When the pull rope 350 pulls the locking pin 340, the piston rod 480 can slide, thereby extracting gas from the rectangular cylinder 430 to unlock the vertical rod 450.

[0066] When the locking pin 340 is pulled by the pull rope 350, the pull rope 350 simultaneously drives the piston rod 480 to slide through the connecting frame 481, causing the piston cylinder 470 to draw gas from the rectangular cylinder 430 through the air pipe 460, reducing the internal pressure. This causes the limit rods 440 to move closer to each other under negative pressure, thereby unlocking the vertical rod 450. This ensures that the vertical rod 450 slides smoothly down to the photovoltaic panel surface under the action of gravity, achieving precise contact, further improving the accuracy and reliability of the inclination measurement, and simplifying the manual operation steps.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
