Description

Technical Field

[0001] The present invention relates to a rapid leveling device and construction method for photovoltaic panel installation. Background Art

[0002] With the transformation of the global energy structure and the rapid development of renewable energy, photovoltaic power generation technology has been widely used due to its clean and sustainable characteristics. As the core component of a photovoltaic power generation system, the installation quality of photovoltaic panels directly affects the power generation efficiency and system stability. During the actual installation process, due to the different inclinations of building roofs, ground or support bases, the leveling of photovoltaic panels becomes a key link. Traditional photovoltaic panel installation methods usually use fixed brackets or simple adjustable feet, which have problems such as low adjustment accuracy, poor adaptability, and low construction efficiency. Especially when installing on complex terrains or non-standard building structures, it is difficult to quickly and accurately achieve the horizontal adjustment of photovoltaic panels.

[0003] Currently, the photovoltaic panel leveling devices on the market mainly rely on bolt adjustment or gasket compensation. Not only are the operations cumbersome, but the adjustment range is also limited, making it difficult to meet the requirements of different inclined walls and complex installation environments. In addition, most traditional photovoltaic panel angle adjustment mechanisms use single-point adjustment methods, which easily lead to uneven stress on the photovoltaic panels, affecting structural stability and even potentially reducing the service life of the photovoltaic panels due to long-term stress concentration.

[0004] Therefore, there is an urgent need for a new type of rapid photovoltaic panel leveling device and construction method that can achieve multi-stage gear adjustment of the feet to adapt to installation bases at different angles, and at the same time have an independent adjustment function for both ends of the photovoltaic panel to improve the leveling efficiency and installation flexibility, thereby enhancing the overall performance and reliability of the photovoltaic system. Summary of the Invention

[0005] The present invention provides a rapid leveling device and construction method for photovoltaic panel installation, which can effectively solve the above problems.

[0006] The present invention is implemented as follows:

[0007] A rapid leveling device for photovoltaic panel installation includes a base plate, an upper plate, a support plate, and a photovoltaic panel body.

[0008] Four groups of gear - type rotary support mechanisms are distributed at the four corners of the bottom of the substrate, and each group of the gear - type rotary support mechanisms can be independently adjusted at multiple angles; the gear - type rotary support mechanism includes a support base, on the top of which a pair of side plates with shaft holes are symmetrically arranged, a universal joint penetrates through the shaft holes of the side plates, and first gear members are fixed at both axial ends thereof. A side plate rotatably arranged on the universal joint, a fixing member arranged between the two side plates, and an upper mounting plate fixed between the side plates through the fixing member, and a second gear member meshing with the first gear member is integrally formed on the lower surface thereof, so as to realize the rotational adjustment of the support base relative to the upper mounting plate, enabling the substrate to adapt to installation walls at different angles;

[0009] An angle adjustment mechanism is arranged on the top of the substrate, which is detachably connected to the photovoltaic panel body and realizes the adjustment of its pitch angle; the angle adjustment mechanism includes a positioning base fixed on the top of the substrate, guide grooves are arranged on both sides thereof, an I - beam parallel to one end of the length direction of the positioning base, a screw drive assembly penetrating through the I - beam, an upper positioning slide fixed on the positioning base, a sliding frame slidably arranged on the upper positioning slide, and a four - link angle adjustment assembly cooperatively connected with the sliding frame;

[0010] The gear - type rotary support mechanism and the angle adjustment mechanism form a cooperative adjustment system to jointly maintain the horizontal reference plane and the preset inclination angle of the photovoltaic panel body;

[0011] A clamping mechanism is arranged on the top of the support plate for clamping and fixing the photovoltaic panel body.

[0012] The beneficial effects of the present invention are as follows:

[0013] (1) Through the cooperative cooperation of four groups of independently adjustable gear - type rotary support mechanisms at the bottom and the angle adjustment mechanism at the top, the present invention realizes the rapid and precise leveling of the photovoltaic panel in a complex installation environment: among them, the gear - type rotary support mechanism adopts an elastic gear meshing design driven by a universal joint, which can automatically compensate for the inclination deviation of non - uniform installation surfaces such as Y - shaped walls and sloping roofs, ensuring that the substrate is dynamically leveled to the horizontal reference plane; and the four - link angle adjustment assembly at the top realizes the stepless precision adjustment of the pitch angle of the photovoltaic panel through the linkage mechanism of screw drive and guide groove constraint; cooperating with the radially synchronous clamping mechanism driven by a spiral groove, a three - level control system from base leveling, angle fine - tuning to stable clamping is formed, and at the same time, it has excellent adaptive ability (the elastic gear members still maintain stable meshing under vibration conditions), significantly solving the technical problems of low leveling efficiency, poor accuracy and limited application scenarios existing in the installation of photovoltaic systems on complex building structures.

[0014] (2) The present invention realizes the automation and high-precision control of the angle adjustment of the photovoltaic panel through an innovative turbine-worm drive system: the servo motor drives the worm to mesh with the turbine teeth on the connecting arc plate, forming a screw drive with self-locking characteristics, driving the sliding base to slide smoothly along the arc-shaped chute of the semi-circular base, and cooperating with the precise alignment of the angle scale and the positioning cursor, the inclination adjustment accuracy of the photovoltaic panel can reach ±0.1°; the design of the limiting edge and the reinforced connecting arc plate not only ensures the controllable movement range of the sliding base (preventing overtravel), but also enhances the overall structural rigidity. It is especially suitable for photovoltaic systems that need to frequently track the sun's angle. Through electric control, seamless integration with the sun tracking system can be achieved. At the same time, the self-locking characteristic of the turbine-worm drive effectively prevents angle deviation caused by wind vibration or vibration, significantly improving the power generation efficiency and operation stability of the photovoltaic system in an automated scenario.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0038] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0039] Embodiment 1

[0040] Referring to Figure 1-2 As shown, a quick leveling device for photovoltaic panel installation includes a base plate 10, an upper plate 50, a support plate 70, and a photovoltaic panel body 90. Among them, sliding grooves 40 are symmetrically arranged on both sides of the top of the base plate 10, and sliding baffles 20 are slidably connected to the sliding grooves 40.

[0041] Specifically, the sliding baffle 20 not only serves as an auxiliary positioning structure for photovoltaic panel installation but also has an aerodynamic optimization function. After the photovoltaic panel body 90 is installed in place, the extended length and position distribution of the two sliding baffles 20 can be flexibly adjusted along the sliding grooves 40 according to the local wind direction characteristics. The turbulence structure formed by the baffles effectively decomposes the frontal wind pressure and reduces the wind vibration effect; its edge adopts a diversion inclined plane design, which blocks the direct impact of strong winds on the edge of the photovoltaic panel while guiding the air flow to smoothly pass through the plate surface gap, achieving a dynamic wind-breaking effect. This slidable and adjustable baffle design not only maintains the lightweight characteristics of the installation structure but also significantly improves the wind uplift resistance and operating stability of the photovoltaic panel system in a harsh wind environment.

[0042] It should be noted that the actual sizes of the sliding baffle 20 and the photovoltaic panel body 90 need to be designed according to actual data, and the sizes of the sliding baffle 20 and the photovoltaic panel body 90 in this case are not set precisely.

[0043] Referring to Figure 1 、 3As shown in FIGS. 8 and 9, four groups of gear - type rotary support mechanisms 30 are distributed at the four corners of the bottom of the substrate 10, and each group of gear - type rotary support mechanisms 30 can be independently adjusted at multiple angles; the gear - type rotary support mechanism 30 includes a support base 300, on the top of which a pair of side plates 301 with shaft holes are symmetrically arranged. The universal joint 302 passes through the shaft holes of the side plates 301, and first gear members 303 are fixed at both axial ends thereof. A side plate 304 rotatably arranged on the universal joint 302, a fixing member 305 arranged between the two side plates 304, and an upper mounting plate 306 fixed between the side plates 304 through the fixing member 305. A second gear member 307 integrally formed on its lower surface meshes with the first gear member 303, thereby realizing the rotational adjustment of the support base 300 relative to the upper mounting plate 306, so that the substrate 10 can adapt to installation walls at different angles. It should be noted that the first gear member 303 and the second gear member 307 are made of nylon or spring steel. When swinging, the tooth surfaces of the gears elastically deform to maintain meshing. Further, the side plate 304 is also provided with a swing - angle limit groove to prevent tooth disengagement caused by excessive deflection.

[0044] Referring to Figure 8-9 shown, the present case also includes an explanation of the adaptive adjustment of the gear - type rotary support mechanism 30 to the Y - shaped wall and the roof slope of the inclined wall:

[0045] Installation situation of the Y - shaped wall:

[0046] The Y - shaped wall usually has a certain forking angle, and its shape is similar to the letter "Y". This structure can be used for specific space division or decorative effects in architecture;

[0047] The gear - type rotary support mechanism 30 can adapt to the complex angle requirements of the Y - shaped wall through its multi - angle adjustment function. Specifically, the four groups of gear - type rotary support mechanisms 30 at the bottom of the substrate 10 can be independently adjusted at multiple angles, so that the substrate can closely fit each forked surface of the Y - shaped wall. The meshing transmission of the first gear member 303 and the second gear member 307 can realize the rotational adjustment of the support base 300 relative to the upper mounting plate 306, so that the substrate 10 can flexibly adjust the angle to adapt to the angle changes of different branches of the Y - shaped wall;

[0048] The design of this support mechanism enables the substrate 10 to quickly find a suitable angle when installed on the Y - shaped wall, reducing the adjustment time and labor intensity during the installation process, and improving the installation accuracy and stability at the same time.

[0049] Roof slope of the inclined wall

[0050] The roof slope usually has a certain inclination angle, and its design is mainly used for drainage, aesthetics or to meet specific building functions. The roof slope angles of different buildings may vary, so the installation equipment needs to be able to adapt to multiple angles;

[0051] The gear - type rotary support mechanism 30 can be adapted to the installation on roof slopes with different gradients. Through its unique gear meshing and rotation adjustment mechanism, the substrate 10 can be flexibly adjusted in angle to match the inclination angle of the roof slope. The first gear member 303 and the second gear member 307 are made of nylon or spring steel, and can maintain elastic deformation of the tooth surface during swinging, so as to maintain a stable meshing state at different angles;

[0052] During the installation process on the roof slope, the multi - angle adjustment ability of the gear - type rotary support mechanism 30 can ensure that the substrate 10 is closely attached to the slope surface, avoiding insecure or unstable installation caused by mismatched angles. In addition, the design of the swing - angle limit groove on the side plate 304 can effectively prevent tooth disengagement caused by excessive deflection, further improving the safety and reliability of the installation.

[0053] Refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, an angle adjustment mechanism 60 is provided at the top of the substrate 10, which is detachably connected to the photovoltaic panel body 90 and realizes the adjustment of its pitch angle; the angle adjustment mechanism 60 includes a positioning base 600 fixed to the top of the substrate 10, with guide grooves 6000 provided on both sides thereof, an I - beam 602 parallel to one end of the positioning base 600 in the length direction, a screw drive assembly passing through the I - beam 602, the screw drive assembly including a screw 6024 and a handwheel 6022 passing through the I - beam 602, an upper positioning slide 6002 fixedly arranged on the positioning base 600, a sliding frame 604 slidably arranged on the upper positioning slide 6002, and a four - link angle adjustment assembly used in cooperation with the sliding frame 604.

[0054] The four-bar angle-adjusting assembly includes first inclined arms 606 symmetrically hinged to both sides of the sliding frame 604, a positioning rod 6060 and a first connecting rod 6066 connecting the sliding frame 604 and the first inclined arms 606, a side fixing plate 6082 for fixing the first inclined arms 606 and the positioning rod 6060, a collar 6084 provided on the side fixing plate 6082 and sleeved on the positioning rod 6060, a pivot seat 608 provided on the adjacent side of the I-beam 602, a second connecting rod 6080 provided between the two pivot seats 608, a second inclined arm 6086 rotatably provided on the second connecting rod 6080, connecting plates 610 symmetrically provided at the other ends of the two first inclined arms 606, a third connecting rod 6102 for connecting the connecting plates 610 and the two first inclined arms 606, and a movable mounting groove 6100 formed on the connecting plates 610; the first inclined arms 606 and the second inclined arm 6086 are linked by the first connecting rod 6066 to form a parallelogram lifting mechanism; a guide post 6064 sleeved on the positioning rod 6060 is slidably connected to the guide groove 6000.

[0055] The gear-type rotary support mechanism 30 and the angle adjustment mechanism 60 constitute a cooperative adjustment system to jointly maintain the horizontal reference plane of the photovoltaic panel body 90 and the preset inclination angle;

[0056] Refer to Figure 6-7 As shown, the clamping mechanism 80 is provided on the top of the support plate 70 for clamping and fixing the photovoltaic panel body 90; the clamping mechanism 80 includes a clamping seat 800, an edge bayonet 8000 formed on the clamping seat 800, an inner ring seat 802 rotatably provided in the middle of the clamping seat 800, a handle 8020 fixedly provided on the inner ring seat 802, a spiral groove 8022 formed on the inner ring seat 802, a slider 8024 slidably provided on the spiral groove 8022, a clamping member 8026 fixedly provided on the top of the slider 8024, and a central shaft 8028 provided in the middle of the clamping seat 800 and the inner ring seat 802; a positioning ring plate 804 is provided on the top of the clamping seat 800, an adaption groove 8040 formed on the positioning ring plate 804 and slidably connected to the clamping member 8026, and an auxiliary member 806 provided on the top of the positioning ring plate 804.

[0057] Specifically, the linkage logic between the gear-type rotary support mechanism 30 and the substrate 10 is as follows;

[0058] When there is an inclination angle on the installation surface, the support base 300 is subjected to an inclined force and deflects. The linkage process is as follows: Due to the inclination of the installation surface, the angle between the support base 300 and the ground contact surface changes, driving the universal joint 302 to deflect. The universal joint 302 allows the support base 300 to swing left and right by ±15°. At the same time, the axial rotation force is transmitted to the first gear members 303 at both ends. The first gear members 303 rotate and mesh with the second gear members 307 on the upper mounting plate 306, pushing the second gear members 307 to rotate. The gear tooth surfaces can be slightly elastically deformed to ensure meshing is maintained during swinging, avoiding jamming or tooth disengagement. The rotation of the second gear members 307 drives the upper mounting plate 306 to axially deflect around the universal joint 302, compensating for the inclination angle of the installation surface. Thus, the four groups of gear-type rotary support mechanisms 30 independently respond to inclination angles in different directions and automatically adjust the height of each angle through gear transmission to make the substrate 10 level. The swing angle limit groove limits the maximum deflection angle of the side plate 304 to prevent gear disengagement caused by excessive swinging.

[0059] The linkage logic flowchart is as follows:

[0060] The installation surface is inclined

[0061] ↓

[0062] The support base 300 deflects → The universal joint 302 rotates

[0063] ↓

[0064] The first gear members 303 rotate → Mesh with the second gear members 307

[0065] ↓

[0066] The angle of the upper mounting plate 306 is adjusted → The substrate 10 is dynamically leveled

[0067] ↓

[0068] The four groups of mechanisms cooperate to compensate → Maintain the horizontal reference plane within an error of ±0.5°.

[0069] Among them, the linkage logic between the angle adjustment mechanism 60 and the photovoltaic panel body 90 is as follows:

[0070] The hand crank 6022 drives → The lead screw 6024 advances → The four-link angle adjustment assembly unfolds → The pitch angle of the photovoltaic panel is precisely adjusted:

[0071] Rotate the hand crank 6022 to drive the lead screw 6024 to rotate, pushing the sliding frame 604 to linearly move along the guide groove 6000. The displacement of the sliding frame 604 pulls the first inclined arm 606 through the first connecting rod 6066. The first inclined arm 606 and the second inclined arm 6086 form a parallelogram linkage through the second connecting rod 6080. The guide post 6064 slides in the guide groove 6000 to constrain the movement trajectory. The connecting plate 610 is driven by the third connecting rod 6102. The inner diameter of the movable mounting groove 6100 is larger than the outer diameter of the third connecting rod 6102, so that the third connecting rod 6102 can move in the movable mounting groove 6100 and drive the photovoltaic panel body 90 to be adjusted.

[0072] The cooperation logic between the clamping mechanism 80 and the leveling system is as follows:

[0073] Rotate the handle 8020 → Radially drive the spiral groove 8022 → Synchronously clamp / release the clamping piece 8026:

[0074] When rotating the handle 8020, the spiral groove 8022 of the inner ring seat 802 forces the slider 8024 to slide radially along the central axis 8028. The clamping piece 8026 moves centripetally synchronously under the guidance of the fitting groove 8040 to achieve four-point synchronous clamping.

[0075] Linkage effect: One-sided operation can balance the clamping force. The pressure sensor feedbacks to the handle LED light. When overloaded, the red light alarms (not shown in the figure) and can be set according to actual needs in actual applications.

[0076] System linkage innovation three-level collaborative control logic

[0077] Wall surface inclination compensation → Substrate leveling → Photovoltaic panel fine adjustment → Clamping and fixing

[0078] ↑ Gear-type rotary support mechanism 30 ↑ Angle adjustment mechanism 60 ↑ Clamping mechanism 80

[0079] The horizontal state of the substrate 10 is fed back to the angle adjustment mechanism 60 through an inclination sensor (not shown in the figure). If the substrate 10 tilts due to wind load, the system automatically triggers the fine adjustment of the lead screw 6024 to maintain the preset inclination angle of the photovoltaic panel. The gear-type rotary support mechanism 30 is responsible for the macroscopic reference plane adjustment, and the angle adjustment mechanism 60 is responsible for the microscopic angle optimization. The two achieve functional decoupling through independent control, but form a synergy through the physical connection of the substrate 10, with an efficiency improvement of 40% compared to the traditional single adjustment method.

[0080] In summary, in this case, a composite transmission chain of gears + four-link + spiral grooves is used to achieve multi-stage motion conversion from the wall to the photovoltaic panel. The gear-type rotating support mechanism 30 and the angle adjustment mechanism 60 form a cascade compensation to cope with the deformation of the installation surface and wind load disturbances. The integrated force feedback module of the hand-cranked wheel 6022 is not shown in the figure and can be set according to actual needs. When the mechanism reaches the limit position, the rotation resistance tactile prompt is automatically increased.

[0081] The macro-leveling of the base plate 10 is achieved through the four sets of gear-type rotating support mechanisms 30 at the bottom. When the installation wall is uneven, the universal joint 302 drives the first gear member 303 to rotate, and meshes with the second gear member 307 at the bottom of the upper installation plate 306 for transmission, and the elastic deformation characteristics of the gears made of nylon / spring steel are used to maintain the meshing, and the limit grooves of the side plates 304 are used to prevent the teeth from coming off, so that the support base 300 can be deflected in multiple directions to adapt to walls with different inclination angles; the angle adjustment mechanism 60 at the top of the base plate 10 drives the screw rod 6024 through the hand-cranked wheel 6022 to push the sliding frame 604 to move along the upper positioning slide 6002, driving the four-bar linkage angle adjustment assembly to work together - the first tilting arm 606 is connected to the guide column 606 through the positioning rod 6060 064 slides along the guide groove 6000, and at the same time, the first connecting rod 6066, the second connecting rod 6080 and the third connecting rod 6102 form a parallelogram transmission, so that the connecting plate 610 drives the support plate 70 to rise and fall through the movable mounting groove 6100, so as to achieve fine adjustment of the pitch angle of the photovoltaic panel body 90; the clamping mechanism 80 drives the inner ring seat 802 to rotate by rotating the handle 8020, and the spiral groove 8022 drives the slider 8024 to move radially, so that the clamping member 8026 slides along the adapter groove 8040 of the positioning ring plate 804 to clamp / loosen the edge of the auxiliary member 806, and finally the gear-type rotating support mechanism 30 and the angle adjustment mechanism 60 cooperate to maintain the horizontal reference plane and the preset inclination angle of the photovoltaic panel, so as to complete rapid leveling and fixation.

[0082] The present invention also includes a construction method of a rapid leveling device for photovoltaic panel installation, as follows:

[0083] S1. Construction preparation:

[0084] Tool and material inspection: confirm that the gear-type rotating support mechanism 30, the angle adjustment mechanism 60, the clamping mechanism 80 and other components are complete, and prepare the hand wheel 6022, screwdriver, level and other tools. At the same time, measure the flatness and inclination angle of the installation wall or ground to determine the preset inclination angle of the photovoltaic panel body 90;

[0085] S2. Installation of the substrate 10 and the gear-type rotary support mechanism 30: Distributively fix the support bases 300 of the four groups of gear-type rotary support mechanisms 30 on the installation surface such as a wall surface or a bracket, ensuring symmetric arrangement. Drive the support base 300 to rotate at multiple angles through the first gear member 303 and the second gear member 307. Then, use a level to detect the levelness of the substrate 10, and independently adjust each group of gear-type rotary support mechanisms 30 until the substrate 10 is completely level;

[0086] S3. Installation and leveling of the angle adjustment mechanism 60: Fix the positioning base 600 on the top of the substrate 10, ensuring that the directions of the two side guide grooves 6000 are parallel to the I-beam 602. Rotate the handwheel 6022 to drive the lead screw 6024, driving the sliding frame 604 to slide along the guide groove 6000. When the sliding frame 604 moves, it pushes the first inclined arm 606 and the second inclined arm 6086 through the first connecting rod 6066, forming a parallelogram lifting mechanism. Observe the position of the movable installation groove 6100 of the connecting plate 610, and adjust it to the preset pitch angle such as the local optimal sunlight angle;

[0087] S4. Installation of the support plate 70 and the photovoltaic panel body 90: Fix the support plate 70 to the connecting plate 610 of the angle adjustment mechanism 60 with bolts. At the same time, fix the photovoltaic panel body 90 to the positioning ring plate 804 through the auxiliary part 806. Rotate the handle 8020, and drive the spiral groove 8022 of the inner ring seat 802 to push the slider 8024 and the clamping part 8026 to move towards the center, clamping the auxiliary part 806;

[0088] S5. Cooperative leveling and final verification: If the installation surface is uneven, compensate for the inclination of the substrate 10 through the gear-type rotary support mechanism 30, and then precisely adjust the inclination angle of the photovoltaic panel body 90 through the angle adjustment mechanism 60. Then, use a level to recheck the horizontal reference plane of the photovoltaic panel body 90, and use a protractor to confirm whether the pitch angle meets the design requirements.

[0089] In step S2, a laser crosshair instrument is used to assist in calibrating the levelness of the substrate 10, and the laser receiver is embedded in the central groove of the substrate 10 "(to improve the installation accuracy).

At the same time, measure the flatness and inclination angle of the installation wall or ground, and determine the preset inclination angle of the photovoltaic panel body (90). S2. Installation of the substrate (10) and the gear-type rotary support mechanism (30): Distributively fix the support bases (300) of the four groups of gear-type rotary support mechanisms (30) on the installation surface (such as a wall or a bracket), ensure symmetric arrangement, drive the support base (300) to rotate at multiple angles through the first gear member (303) and the second gear member (307), and then use a level to detect the levelness of the substrate (10), and independently adjust each group of gear-type rotary support mechanisms (30) until the substrate (10) is completely level. S3. Installation and leveling of the angle adjustment mechanism (60): Fix the positioning base (600) on the top of the substrate (10), ensure that the directions of the two guide grooves (6000) are parallel to the I-beam (602), rotate the handwheel (6022) to drive the lead screw (6024), drive the sliding frame (604) to slide along the guide groove (6000).
