Description
Technical Field
[0001] This invention relates to the field of photovoltaic module support technology, specifically to a photovoltaic panel support device and method based on helical piles. Background Technology
[0002] A photovoltaic (PV) panel is a semiconductor device that directly converts solar radiation energy into electrical energy using the photovoltaic effect. It is typically composed of multiple photovoltaic cells connected in series and parallel and is the core component of a solar power generation system. The PV panel support structure, as an important part of the PV power generation system, has the main function of fixing the PV panels in a specific position according to the designed tilt angle and azimuth angle. It must not only withstand various static and dynamic loads such as the weight of the PV panels, wind load, and snow load, but also ensure that the PV panels maintain the optimal installation angle over a long period of time to obtain the maximum solar radiation reception, thereby ensuring the power generation efficiency and operational safety of the PV power generation system.
[0003] Chinese patent document (publication number: CN119675555A) discloses a photovoltaic panel and its supporting device, belonging to the field of photovoltaic panel technology. It includes a photovoltaic panel body, a support frame fixedly installed on the lower side of the photovoltaic panel body, a support column fixedly connected to the bottom of the support frame, a rotating frame rotatably connected to the support column, an adjustment mechanism rotatably connected to the rotating frame, a protective cover fixedly connected to the adjustment frame, a weeding mechanism rotatably connected to the bottom of the adjustment frame, and a movable frame slidably fitted inside the adjustment frame. In this invention, during the use of the photovoltaic panel, when the weeds under the photovoltaic panel grow to a certain height, the rotating frame can drive the blade to rotate, allowing the blade to automatically weed the weeds under the photovoltaic panel. This ensures that the sunlight in the area under the photovoltaic panel is not blocked, reducing the potential threat to the photovoltaic system, ensuring the long-term stable operation of the photovoltaic equipment, maintaining the power generation efficiency of the photovoltaic panel, reducing manual maintenance costs, and improving the overall management level.
[0004] In existing permafrost areas, photovoltaic support structures experience multi-directional composite displacements in the pile foundations due to seasonal freeze-thaw cycles, including rising, falling, tilting, and horizontal shifting. This can lead to asynchronous displacements at various support points of the photovoltaic panel brackets, posing safety hazards to the photovoltaic panel support frame and even causing the photovoltaic panels to malfunction. Furthermore, traditional solutions employ a single pile foundation arrangement with uniform deep burial or all shallow burial, which cannot reconcile the conflict between construction costs and stability benchmarks. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic panel support device and method based on helical piles. By employing a differentiated arrangement of shallowly buried helical piles and deeply buried reference piles at both ends, cost and stability are balanced. A three-dimensional adjustment mechanism is installed on the top of the support plate, transmitting pile displacement to the detection frame via an offset transmission component. This, combined with distributed electrode contact plates and electrode plates, constructs a triple detection mechanism for height, tilt, and lateral offset. The spatial layout of the electrodes enables automatic signal differentiation and prevents false triggering. When pile displacement occurs due to changes in permafrost, the corresponding electrode conducts, triggering a motor for reverse compensation. After returning to the initial position, the motor automatically disconnects, achieving closed-loop correction. Simultaneously, a sliding plate design combined with a spherical hinge and clearance fit is used to achieve flexible decoupling of composite displacement transmission, avoiding stress concentration and significantly improving the safety and service life of the device in permafrost regions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A photovoltaic panel support device based on a helical pile includes a support plate fixedly installed on the top of the helical pile. A three-dimensional adjustment mechanism is provided on the top of the support plate, with the top of the mechanism connected to the bottom of a support rod. A connecting plate is fixedly mounted on the support rod, extending to one side and fixedly connected to a state transmission frame. A reference rod passes vertically through the state transmission frame, and a movable sleeve is movably fitted onto the reference rod. The outer side of the movable sleeve is connected to the inner wall of the state transmission frame via an offset transmission component. Reference frames are spaced apart on the outer periphery of the state transmission frame and fixedly connected to the outer surface of the reference rod. Electrode plates are respectively installed on the reference frames and the reference rod, and electrode contact plates are respectively installed on the state transmission frame and the movable sleeve. The electrode plates and electrode contact plates are electrically connected to control the three-dimensional adjustment mechanism. When the helical pile extending into the ground displaces, it drives the corresponding electrode plate to connect with the electrode contact plate, controlling the three-dimensional adjustment mechanism to bring the support rod and the reference rod to their initial height and parallel position.
[0008] Preferably, the connecting plate has a U-shaped structure, and both ends of the connecting plate are fixedly connected to the outer wall of the state transmission frame by connecting rods. The connecting rods pass through the reference frame and maintain a distance from the through opening. The offset transmission component includes an n-shaped plate, a sliding plate, and a spherical hinge. The end of the n-shaped plate away from its own opening is fixedly connected to the inner wall of the state transmission frame. The opening end of the n-shaped plate faces the moving sleeve, and the sliding plate is slidably installed inside the opening. The sliding plate and the moving sleeve are connected by a spherical hinge. A pin is inserted through the n-shaped plate perpendicular to its own opening direction. An enlarged diameter hole is opened on the sliding plate. The inner diameter of the enlarged diameter hole is larger than the outer diameter of the pin and is sleeved on the pin.
[0009] Preferably, fixed rings are provided at intervals on the reference rod at both ends of the movable sleeve. The ends of the fixed rings close to the movable sleeve are connected to the third electrode contact plates by return springs. Both third electrode contact plates are slidably sleeved on the reference rod. Third electrode plates are provided at both ends of the movable sleeve. When the movable sleeve is displaced vertically due to the misalignment of the helical pile, the third electrode plate at one end of the movable sleeve and the adjacent third electrode contact plate come into contact and connect. The electrical connection triggers the three-dimensional adjustment mechanism to move in the opposite direction until the movable sleeve returns to its initial position. The third electrode plate and the third electrode contact plate are disconnected, so that the support rod remains in the initial position to maintain the stability of the photovoltaic panel.
[0010] Preferably, a first electrode contact plate is provided on the top of the outer periphery of the state transmission frame, and a first electrode plate is provided on the top of the inner periphery of the reference frame corresponding to the first electrode contact plate. The first electrode plate is fixedly connected to the inner wall of the reference frame by a reset spring. The first electrode plate is located below the first electrode contact plate and does not intersect with it when it moves horizontally. When the state transmission frame tilts to one side, the first electrode contact plate on this side contacts and connects with the adjacent first electrode plate. The electrical connection triggers the three-dimensional adjustment mechanism to move in the opposite direction until the state transmission frame returns to its initial position. The first electrode plate is disconnected from the first electrode contact plate, so that the support rod remains in the initial position to maintain the stability of the photovoltaic panel.
[0011] Preferably, a second electrode contact plate is provided on the outer periphery of the state transmission frame, and a second electrode plate is provided on the inner periphery of the reference frame corresponding to the second electrode contact plate. The second electrode plate is fixedly connected to the inner wall of the reference frame by a reset spring. The second electrode contact plate and the second electrode plate are on the same horizontal plane. When the state transmission frame moves horizontally to one side, the second electrode contact plate on this side contacts and connects with the adjacent second electrode plate. The electrical connection triggers the three-dimensional adjustment mechanism to move in the opposite direction until the state transmission frame returns to its initial position. The second electrode contact plate and the second electrode plate are disconnected, so that the support rod remains in the initial position to maintain the stability of the photovoltaic panel.
[0012] Preferably, reference piles are set at both ends of several spiral piles arranged in a linear array, an extension rod is fixed at the top of the reference pile, a truss is fixedly connected between two extension rods, and a reference rod is fixed on the truss in the vertical direction.
[0013] Preferably, the three-dimensional adjustment mechanism includes a first translation adjustment frame fixed to the top of the support plate, a second translation adjustment frame fixed on the first translation adjustment frame, and the adjustment directions of the two sets of translation adjustment frames being perpendicular; a first tilt adjustment frame is provided on the second translation adjustment frame, a second tilt adjustment frame is fixed on the first tilt adjustment frame, and the adjustment directions of the two sets of tilt adjustment frames being perpendicular; a lifting adjustment frame is fixed on the second tilt adjustment frame; and a support rod is fixedly connected to the lifting adjustment frame.
[0014] Preferably, the lifting adjustment frame includes a base, which is a hollow cavity structure. A guide sleeve is provided through the top of the base, and a stabilizing frame is fixed on the outer periphery of the guide sleeve. A lifting rod is provided inside the guide sleeve through a keyway. The end of the lifting rod away from the base is fixedly connected to the bottom end of a support rod. The lifting rod is a hollow structure with threads on its inner wall. A lifting screw is screwed into the hollow threaded structure of the lifting rod. One end of the lifting screw extends into the base and is provided with a first bevel gear at its end. A fifth motor is provided in the base located on one side of the first bevel gear. The fifth motor is mounted with a second bevel gear through a rotating shaft. The meshing of the first bevel gear and the second bevel gear adjusts the vertical displacement of the lifting rod.
[0015] Preferably, a protective cylinder is fixed to the top of the support plate, the top of the protective cylinder extends upward to the guide sleeve, a protective sleeve is fixed to the top of the protective cylinder, the protective sleeve is a retractable deformable sleeve, and the top of the protective sleeve is fixed to the bottom of the support rod.
[0016] A method of using a photovoltaic panel support device based on helical piles includes the following steps:
[0017] S1. Multiple spiral piles are arranged in a linear array and shallowly buried in the permafrost layer. Reference piles are deeply buried on the outside of the spiral piles at both ends of each linear array.
[0018] S2. A support plate is fixed at the top of the helical pile by a flange. A three-dimensional adjustment mechanism is installed on the support plate. A support rod is fixedly connected to the top of the three-dimensional adjustment mechanism. A photovoltaic panel bracket is installed at the top of the support rod. A U-shaped connecting plate is fixed in the middle of the support rod. A state transmission frame is fixedly connected to both ends of the connecting plate.
[0019] S3. An extension rod is fixed at the top of the reference piles at both ends, and a truss is fixed between the extension rods. A reference rod is vertically installed on the truss. A movable sleeve is movably fitted on the reference rod, and the movable sleeve is connected to the state transmission frame through the offset transmission component.
[0020] S4. A reference frame is fixed on the outer periphery of the reference rod. Electrode plates are installed on the reference frame and the reference rod. Electrode contact plates are installed on the state transmission frame and the moving sleeve.
[0021] S5. When the helical pile undergoes displacement:
[0022] S51. If the moving sleeve slides up and down along the reference rod, the trigger electrode plate and the third electrode contact plate are connected, driving the fifth motor of the lifting adjustment frame to move in the opposite direction; if the state transmission frame is tilted, the first electrode contact plate at its top contacts the first electrode plate of the reference frame, driving the motor of the tilt adjustment frame; if the state transmission frame is horizontally offset, the second electrode contact plate in its middle contacts the second electrode plate, driving the motor of the translation adjustment frame.
[0023] S52, the three-dimensional adjustment mechanism performs reverse compensation motion until the support rod and the reference rod are restored to parallel and at the initial height.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. In this invention, the three-dimensional adjustment mechanism set on the top of the support plate is organically combined with the displacement detection component based on the electrode plate and electrode contact plate to construct a triple detection mechanism for height, tilt, and lateral offset. This mechanism can capture the displacement of the helical pile caused by seasonal permafrost changes in real time and accurately trigger the corresponding motor to perform reverse compensation movement, avoiding the instability problem of the support rod caused by the rise or fall or tilt of the foundation in traditional photovoltaic support structures. More importantly, the use of electrode contact detection to replace the traditional displacement sensor has higher reliability and anti-interference ability in the extreme environment of low temperature and strong vibration in the permafrost region. It avoids false alarms or failures caused by electronic sensors due to temperature drift, condensation, freezing failure, etc. At the same time, the closed-loop control mode of starting adjustment when the electrode is turned on and stopping when it is turned off does not require complex signal processing and threshold calibration, ensuring that the support rod always remains parallel to the reference rod and at the initial height, effectively maintaining the optimal tilt angle and stress state of the photovoltaic panel.
[0026] 2. This invention constructs a bidirectional height detection mechanism by setting fixed rings at intervals between the two ends of the movable sleeve on the reference rod, and connecting the third electrode contact plate slidably sleeved on the reference rod via a return spring. Corresponding third electrode plates are set at both ends of the movable sleeve. Simultaneously, first electrode contact plates are set at the top periphery of the state transmission frame, and a first electrode plate fixedly connected to the top periphery of the reference frame via a return spring is set at a corresponding position on the top periphery of the reference frame. The first electrode plate is positioned below the first electrode contact plate, with the two horizontally shifted without intersecting, thus constructing a detection mechanism specifically for tilt deviation. Furthermore, second electrode contact plates are set in the middle portion of the outer periphery of the state transmission frame, on the reference... A second electrode plate, fixedly connected by a reset spring, is installed at the corresponding position in the center of the frame. The second electrode contact plate and the second electrode plate are placed on the same horizontal plane, constructing a detection mechanism specifically for horizontal displacement. This triple detection mechanism can accurately identify multiple displacements of the helical pile caused by changes in permafrost, such as rising, falling, tilting, and horizontal displacement. It can also achieve automatic signal differentiation through clever spatial layout, effectively avoiding false triggering between different types of displacements and ensuring independent and reliable control of height adjustment, tilt adjustment, and translation adjustment. This effectively maintains the optimal installation angle and stress state of the photovoltaic panel, extending the service life and long-term reliability of the support device in high-altitude and cold regions.
[0027] 3. In this invention, the displacement of the helical pile is transmitted to the state transmission frame by the planar sliding of the sliding plate in the opening of the n-shaped plate in the offset transmission component, combined with the multi-degree-of-freedom transmission of the spherical hinge. This triggers the corresponding electrode contact to achieve correction, which not only improves the structural safety of the photovoltaic panel in complex geological environments, but also extends the service life of the support device. More importantly, the clearance fit design with the inner diameter of the enlarged hole being larger than the outer diameter of the pin allows the sliding plate and the n-shaped plate to move relative to each other while maintaining planar contact. This achieves automatic decoupling and precise transmission of the composite displacement caused by uneven frost heave of frozen soil, avoids fatigue cracking of the connectors caused by stress concentration in rigid connections, and enhances the device's adaptability to freeze-thaw cycles and long-term durability.
[0028] 4. This invention constructs a system combining differentiated depth arrangement and benchmark positioning by burying multiple helical piles in a linear array at shallow intervals in the frozen soil layer, and deeply burying reference piles on the outer side of the helical piles at both ends of each linear array. This system can fully adapt to the seasonal freeze-thaw cycle of the frozen soil layer by utilizing the shallow burial design of the helical piles, and can also reduce construction costs. Furthermore, the deep burial of the reference piles penetrates the active freeze-thaw layer to reach the stable soil layer, providing a fixed benchmark for the entire photovoltaic support system that is not affected by seasonal changes. This avoids the problem of pile uplift or breakage caused by the uniform burial depth of traditional photovoltaic pile foundations in frozen soil areas. The reference piles are buried below the active freeze-thaw layer to form a highly stable spatial benchmark line. The benchmark rod is fixed to the top of the benchmark pile. The state transmission frame and the moving sleeve always use the benchmark rod as a reference for displacement detection and trigger the corresponding electrode to achieve independent correction. This not only improves the overall flatness and installation accuracy of the photovoltaic array in the frozen soil environment, but also enhances the ability of the support system to resist the cumulative deformation of freeze-thaw settlement.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

Furthermore, terms such as "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0042] Example 1:
[0043] Figures 1-10 As shown, a photovoltaic panel support device based on a helical pile includes a support plate 19 fixedly installed on the top of the helical pile 15. A three-dimensional adjustment mechanism is provided on the top of the support plate 19, and the top of the three-dimensional adjustment mechanism is connected to the bottom end of a support rod 12. A connecting plate 18 is fixedly installed on the support rod 12, and the connecting plate 18 extends to one side and is fixedly connected to a state transmission frame 33. A reference rod 32 is vertically inserted inside the state transmission frame 33, and a movable sleeve 39 is movably fitted on the reference rod 32. Offset transmission occurs between the outer side of the movable sleeve 39 and the inner wall of the state transmission frame 33. The components are connected, with reference frames 20 spaced apart on the outer periphery of the state transmission frame 33. The reference frames 20 are fixedly connected to the outer periphery of the reference rod 32. Electrode plates are respectively set on the reference frames 20 and the reference rod 32, and electrode contact plates are respectively set on the state transmission frame 33 and the movable sleeve 39. The electrode plates and electrode contact plates are electrically connected to control the three-dimensional adjustment mechanism. When the helical pile 15 extending into the ground is displaced, it will drive the corresponding electrode plate to connect with the electrode contact plate, controlling the operation of the three-dimensional adjustment mechanism to make the support rod 12 and the reference rod 32 at the initial height and parallel position.
[0044] Among them, the helical pile 15 is screwed into the ground along the helical direction, and the support plate 19 is fixedly connected to the flange at the top of the helical pile by bolts; the top of the support rod 12 is fixedly connected to the photovoltaic panel frame, and a suitable diagonal brace is set between the photovoltaic panel frame and the support rod 12 to provide support and stability.
[0045] The two ends of the reference frame 20 along the axial direction of the reference rod 32 are fixedly connected to the outer peripheral surface of the reference rod 32 by a horizontal plate. Since the reference rod 32 is fixedly connected to a structure with a vertical standard, it provides a reference for this device. The reference rod 32 transmits the vertical standard to the reference frame 20 and provides a reference for the state transmission frame 33.
[0046] The motor in the three-dimensional adjustment mechanism can be directly controlled to make adjustments through the connection between the electrode plate and the electrode contact plate; the electrode plate, the electrode contact plate and the corresponding motor are electrically connected and connected to an external power supply, which is a technical phenomenon and will not be elaborated here.
[0047] Alternatively, the signal output system can be controlled by the connection between the electrode plate and the electrode contact plate. The signal output system is connected to the PLC control system, and the PLC then controls the corresponding motor to adjust its position. A low-voltage power supply, generally below 5V, is used between the electrode plate and the electrode contact plate. The low-voltage power supply helps to reduce the risk of electric arcing during the contact process. A stepper motor or a servo motor is selected as the motor.
[0048] In this invention, a three-dimensional adjustment mechanism set on the top of the support plate 19 is organically combined with a displacement detection component based on the electrode plate and electrode contact plate to construct a triple detection mechanism for height, tilt, and lateral offset. This mechanism can capture the displacement of the helical pile 15 caused by seasonal permafrost changes in real time and accurately trigger the corresponding motor for reverse compensation movement, avoiding the instability of the support rod caused by the rise or fall or tilt of the foundation in traditional photovoltaic support structures. More importantly, the use of electrode contact detection to replace the traditional displacement sensor has higher reliability and anti-interference ability in the extreme environment of low temperature and strong vibration in the permafrost region. It avoids false alarms or failures caused by electronic sensors due to temperature drift, condensation, freezing failure, etc. At the same time, the closed-loop control mode of starting adjustment when the electrode is turned on and stopping when it is turned off does not require complex signal processing and threshold calibration, ensuring that the support rod 12 always remains parallel to the reference rod 32 and at the initial height, effectively maintaining the optimal tilt angle and stress state of the photovoltaic panel 11.
[0049] Furthermore, the connecting plate 18 has a U-shaped structure, and both ends of the connecting plate 18 are fixedly connected to the outer wall of the state transmission frame 33 by connecting rods 34 respectively; the offset transmission assembly includes an n-shaped plate 42, a sliding plate 41, and a spherical hinge 40. The end of the n-shaped plate 42 away from its own opening is fixedly connected to the inner wall of the state transmission frame 33. The opening end of the n-shaped plate 42 faces the moving sleeve 39, and the sliding plate 41 is slidably installed inside the opening. The sliding plate 41 and the moving sleeve 39 are connected by the spherical hinge 40; a pin 43 is inserted through the n-shaped plate 42 perpendicular to its own opening direction. An enlarged diameter hole 46 is opened on the sliding plate 41. The inner diameter of the enlarged diameter hole 46 is larger than the outer diameter of the pin and is sleeved on the pin 43.
[0050] It should be noted that the sliding plate 41 slides between the openings of the n-shaped plate 42, forming a planar sliding pair. Since the inner diameter of the enlarged hole 46 is larger than the outer diameter of the pin 43, the sliding plate 41 and the n-shaped plate 42 can maintain relative movement even when they are in planar contact. In seasonally frozen soil areas, if frozen soil occurs or the frozen soil thaws, the helical pile 15 will shift or tilt with the change of the soil. When the helical pile 15 shifts or tilts, the sliding plate 41, the n-shaped plate 42, etc., in conjunction with the spherical hinge 40, transmit the position change of the helical pile 15 to the state transmission frame 33 and the moving sleeve 39, and compare it with the reference frame 20 and the reference rod 32. If there is a deviation, the electrode plate will be connected. The electrical connection triggers the three-dimensional adjustment mechanism to automatically adjust the structure of the top of the support plate 19. Finally, the support rod 12 and the reference rod 32 are in the initial height and parallel position, so that every support at the bottom of the photovoltaic panel structure is in a stable state, ensuring the stability of the overall structure of the photovoltaic panel.
[0051] The spherical hinge 40 includes a ball head and a ball socket. The spherical end of the ball head is placed in the spherical cavity of the ball socket to form a spherical fit. The outer wall of the ball socket is provided with an opening groove. The other end of the ball head is connected to the slide plate 41 to be slide. The bottom of the ball socket is fixed to the outer wall of the movable sleeve 39.
[0052] The connecting rod 34 passes through the reference frame 20, and a clearance is maintained between the connecting rod 34 and the through opening on the reference frame 20 to form a clearance space; when the connecting rod 34 deflects, the connecting rod 34 and the reference frame 20 do not come into contact, thus avoiding interference.
[0053] Furthermore, fixing rings 44 are respectively set at intervals on the reference rod 32 at both ends of the movable sleeve 39. The ends of the fixing rings 44 close to the movable sleeve 39 are respectively connected to the third electrode contact plate 45 through the return spring. Both third electrode contact plates 45 are slidably sleeved on the reference rod 32. Third electrode plates are respectively set at both ends of the movable sleeve 39. When the movable sleeve 39 is affected by the misalignment of the helical pile 15 and causes vertical displacement, the third electrode plate at one end of the movable sleeve 39 and the adjacent third electrode contact plate 45 come into contact and connect. The electrical connection triggers the three-dimensional adjustment mechanism to move in the opposite direction until the movable sleeve 39 returns to the initial position. The third electrode plate and the third electrode contact plate 45 are disconnected, so that the support rod 12 is kept in the initial position to maintain the stability of the photovoltaic panel.
[0054] The electrode plate includes a first electrode plate 36, a second electrode plate 38, and a third electrode plate; the electrode contact plate includes a first electrode contact plate 35, a second electrode contact plate 37, and a third electrode contact plate 45.
[0055] The connecting wires of the symmetrically arranged electrode plates and electrode contact plates can control the same motor, but control the motor to run in opposite directions, ensuring that the adjustment tends to be close to the center position.
[0056] like Figure 8 As shown, when the reference frame 20 and the state transmission frame 33 are only close to each other in the horizontal direction, the second electrode contact plate 37 will contact and communicate with the second electrode plate 38, while the first electrode contact plate 35 and the first electrode plate 36 will not contact each other, thus avoiding false triggering. Since the second electrode contact plate 37 and the second electrode plate 38 are located near the rotation center of the state transmission frame 33, when the state transmission frame 33 only tilts (for example, rotates around the rotation center), the horizontal offset of the second electrode contact plate 37 is small and insufficient to contact the second electrode plate 38. Therefore, the horizontal correction action will not be falsely triggered, further ensuring the accuracy of detection and avoiding false triggering and misalignment. Furthermore, a first electrode contact plate 35 is respectively provided on the top of the outer periphery of the state transmission frame 33, and a first electrode plate 36 is respectively provided on the top of the inner periphery of the reference frame 20 corresponding to the first electrode contact plate 35; the first electrode plate 36 is fixedly connected to the inner wall of the reference frame 20 by a reset spring, and the first electrode plate 36 is located below the first electrode contact plate 35 and does not intersect when horizontally translated; when the state transmission frame 33 tilts to one side, the first electrode contact plate 35 on this side contacts and connects with the adjacent first electrode plate 36, and the electrical connection triggers the three-dimensional adjustment mechanism to move in the opposite direction until the state transmission frame 33 returns to the initial position, the first electrode plate 36 disconnects from the first electrode contact plate 35, so that the support rod 12 is kept in the initial position to maintain the stability of the photovoltaic panel. Furthermore, a second electrode contact plate 37 is respectively provided on the outer periphery of the state transmission frame 33, and a second electrode plate 38 is respectively provided on the inner periphery of the reference frame 20 corresponding to the second electrode contact plate 37. The second electrode plate 38 is fixedly connected to the inner wall of the reference frame 20 by a reset spring. The second electrode contact plate 37 and the second electrode plate 38 are on the same horizontal plane. When the state transmission frame 33 moves horizontally to one side, the second electrode contact plate 37 on this side contacts and connects with the adjacent second electrode plate 38. The electrical connection triggers the three-dimensional adjustment mechanism to move in the opposite direction until the state transmission frame 33 returns to its initial position. The second electrode contact plate 37 and the second electrode plate 38 are disconnected, so that the support rod 12 is kept in the initial position to maintain the stability of the photovoltaic panel.
[0057] The multi-detection mechanism can accurately identify the displacement of the helical pile 15 in multiple directions, such as rising, falling, tilting, and horizontal offset, caused by changes in permafrost. It can also achieve automatic signal differentiation through clever spatial layout, effectively avoiding false triggering between different types of displacement, and ensuring independent and reliable control of height adjustment, tilt adjustment and translation adjustment. It can effectively maintain the optimal installation angle and stress state of the photovoltaic panel 11, and extend the service life and long-term reliability of the support device in high-altitude and cold regions.
[0058] Furthermore, reference piles 16 are respectively set at both ends of several spiral piles 15 arranged in a linear array. An extension rod 17 is fixed at the top of the reference pile 16, and a truss 13 is fixedly connected between the two extension rods 17. A reference rod 32 is fixed on the truss 13 along the vertical direction.
[0059] It should be noted that the reference pile 16 can be a deep foundation helical pile, a concrete pile, or a rock anchor. A stable pile foundation can be used as a reference.
[0060] A monitoring instrument can also be installed on truss 13 to monitor the horizontal, vertical, or tilt angles to ensure the reliability of the standard.
[0061] Furthermore, the three-dimensional adjustment mechanism includes a first translation adjustment frame 21 fixedly mounted on the top of the support plate 19, a second translation adjustment frame 23 fixedly mounted on the first translation adjustment frame 21, and the adjustment directions of the two sets of translation adjustment frames being perpendicular; a first tilt adjustment frame 25 is provided on the second translation adjustment frame 23, a second tilt adjustment frame 27 is fixedly mounted on the first tilt adjustment frame 25, and the adjustment directions of the two sets of tilt adjustment frames being perpendicular; a lifting adjustment frame 29 is fixedly mounted on the second tilt adjustment frame 27; and a support rod 12 is fixedly connected to the lifting adjustment frame 29.
[0062] The first translation adjustment frame 21 and the second translation adjustment frame 23 have similar structures and are used to adjust the displacement in the X and Y directions. Both sets of translation adjustment frames have spaced-apart brackets. Two guide rods and a screw are connected between the two brackets. A translation plate is slidably sleeved on the guide rods. The screw is connected to the translation plate by a screw connection. The end of the screw is connected to a motor. The first translation adjustment frame 21 is controlled by a first motor 22, and the second translation adjustment frame 23 is controlled by a second motor 24. The second translation adjustment frame 23 is fixedly installed on the translation plate of the first translation adjustment frame 21.
[0063] The first tilt adjustment frame 25 and the second tilt adjustment frame 27 have similar structures and are used to adjust the tilt angles in the X and Y directions. Both tilt adjustment frames have a base plate, on which two sets of arc-shaped guide plates are fixed at intervals. A worm gear tooth segment is fixed between the two arc-shaped guide plates. Tilt adjustment plates are set on the two arc-shaped guide plates along the arc direction. Arc-shaped sliding connection is achieved by limiting sliders and limiting rods. A worm is rotatably set on the tilt adjustment plate. A motor is set at one end of the worm. The worm meshes with the worm gear to drive the tilt angle of the tilt adjustment plate. The first tilt adjustment frame 25 is controlled by a third motor 26, and the second tilt adjustment frame 27 is controlled by a fourth motor 28. The second tilt adjustment frame 27 is mounted on the tilt adjustment plate of the first tilt adjustment frame 25.
[0064] Furthermore, the lifting adjustment frame 29 includes a base, which is a hollow cavity structure. A guide sleeve 47 is provided through the top of the base. A stabilizing frame 30 is fixedly provided on the outer periphery of the guide sleeve 47. A lifting rod 31 is provided inside the guide sleeve 47 through a keyway. The end of the lifting rod 31 away from the base is fixedly connected to the bottom end of the support rod 12. The lifting rod 31 is a hollow structure with threads on its inner wall. A lifting screw is screwed into the hollow threaded structure of the lifting rod 31. One end of the lifting screw extends into the base and is provided with a first bevel gear at its end. A fifth motor is provided in the base located on one side of the first bevel gear. The fifth motor is mounted with a second bevel gear through a rotating shaft. The first bevel gear and the second bevel gear mesh to adjust the vertical displacement of the lifting rod 31.
[0065] Among them, multiple legs of the stabilizing frame 30 are fixed to the tilt adjustment plate of the second tilt adjustment frame 27;
[0066] When the electrode plate is connected to the electrode contact plate, it drives the first motor, the second motor, the third motor, the fourth motor and the fifth motor respectively to further adjust the displacement or angle and maintain the initial height and vertical position.
[0067] Furthermore, a protective sleeve 14 is fixedly provided on the top of the support plate 19, the top of the protective sleeve 14 extends upward to the guide sleeve 47, and a protective sleeve 48 is fixedly provided on the top of the protective sleeve 14. The protective sleeve 48 is a retractable deformable sleeve, and the top of the protective sleeve 48 is fixed to the bottom of the support rod 12.
[0068] It should be noted that both the protective cylinder 14 and the protective sleeve 48 are for protecting the three-dimensional adjustment mechanism to prevent external impurities from entering and affecting the operation of the components. The protective cylinder 14 is mainly for structural support and protection, while the protective sleeve 48 is a retractable corrugated or pleated sleeve. The upper end is fixed to the bottom of the support rod 12 and can be secured by a buckle or pressure ring. The middle part is corrugated or pleated to allow the structure to move forward, backward, left, right, or tilt and deform. The lower end is sealed and fixed to the support plate 19 to prevent dust and moisture from entering the mechanism and to keep the lubrication system clean.
[0069] Working principle:
[0070] In use, multiple helical piles 15 are arranged in a linear array and shallowly buried in the soil. At the outer sides of the helical piles 15 at both ends of each linear array, deeply buried reference piles 16 are respectively set. The tops of the helical piles 15 and the reference piles 16 are supported by support rods 12. The reference piles 16 at both ends of the array are fixedly connected by trusses 13. At the position of the trusses 13 near the helical piles 15, reference rods 32 are vertically fixed.
[0071] The top of the helical pile 15 is fixedly connected to the support plate 19 via a fixed flange. A three-dimensional adjustment mechanism is fixedly mounted on the support plate 19, and a support rod 12 is fixedly connected to the top of the three-dimensional adjustment mechanism. The top of the support rod 12 is fixedly connected to the bracket of the photovoltaic panel 11, and the middle of the support rod 12 is fixedly connected to the U-shaped connecting plate 18. The two ends of the U-shaped structure of the connecting plate 18 are fixedly connected to the state transmission frame 33. When the helical pile 15 is displaced, causing the state transmission frame 33 to shift, a relative movement occurs between the state transmission frame 33 and the reference rod 32, thereby triggering the conductive connection between the electrode plate and the electrode contact plate, driving the corresponding motor to rotate. This realizes the reverse compensation movement of the three-dimensional adjustment mechanism for adjustment, ultimately restoring the support rod 12 to its initial height and vertical position, maintaining the stability of the photovoltaic panel 11.
[0072] When seasonal freezing causes displacement or tilting of the shallowly buried helical pile 15, the support plate 19 at the top of the helical pile 15 drives the three-dimensional adjustment mechanism to shift, causing the connecting plate 18 fixed to the middle of the support rod 12 to drive the state transmission frame 33 to shift; at this time, relative movement occurs between the state transmission frame 33 and the reference rod 32, triggering the following automatic correction mechanism:
[0073] Height deviation correction: When the helical pile 15 sinks or rises, the moving sleeve 39 is driven to slide along the reference rod 32 through the offset transmission component (the sliding plate 41 slides in the n-shaped plate 42 and is transmitted through the ball hinge 40); if the moving sleeve 39 moves upward, its top third electrode plate contacts the upper adjacent third electrode contact plate 45; if it moves downward, the bottom third electrode plate contacts the bottom adjacent third electrode contact plate 45, the electrode conduction triggers the fifth motor of the lifting adjustment frame 29, driving the lifting rod 31 to move in the opposite direction until the moving sleeve 39 is reset, maintaining the initial height of the support rod 12;
[0074] Tilt deviation correction (see) Figure 8 When the state transmission frame 33 is tilted, the first electrode contact plate 35 at its top contacts the first electrode plate 36 inside the reference frame 20; the electrode conduction controls the third motor 26 of the first tilt adjustment frame 25 or the fourth motor 28 of the second tilt adjustment frame 27 to adjust the tilt angle of the support rod 12 to the reset.
[0075] Lateral offset: When the state transmission frame 33 is horizontally offset, the middle second electrode contact plate 37 contacts the second electrode plate 38 of the reference frame 20, triggering the first motor 22 of the first translation adjustment frame 21 or the second motor 24 of the second translation adjustment frame 23 to move laterally for correction.
[0076] Displacement transmission mechanism: The offset is transmitted to the slide plate 41 via the spherical hinge 40. The slide plate 41 slides within the n-shaped plate 42. The clearance fit between the enlarged hole 46 and the pin 43 allows for planar displacement.
[0077] The displacement of the helical pile 15 is transmitted to the state transmission frame 33 through components such as the connecting plate 18 and the connecting rod 34, triggering electrode contact;
[0078] During the calibration process, the adjustment stops when the electrode is disconnected, ensuring that the support rod 12 and the reference rod 32 remain parallel and at the preset height. The protective cylinder 14 and the corrugated protective sleeve 48 seal the three-dimensional adjustment mechanism to prevent dust and moisture. The deeply buried reference pile 16 provides a stable reference through the truss 13, and a monitoring instrument can be added if necessary to enhance reliability.
[0079] By combining a triple electrode detection mechanism (height / tilt / lateral offset) with a multi-degree-of-freedom adjustment mechanism (XYZ translation + XY tilt + Z lifting), real-time compensation for permafrost displacement is achieved, ensuring the power generation efficiency and structural safety of photovoltaic panel 11.
