In order to adapt to the slope change, the conventional method includes: 1) adjusting the verticality of a single stand by cutting the bottom end of the stand or using an adjustable base; 2) installing purlins on the main beam with a preset inclination to support photovoltaic modules. These structures rely on manual measurement and leveling one by one, and it is necessary to ensure that the top plane of the support is horizontal or forms a uniform inclined plane.

[0027] As shown in the accompanying Figure 1 to the accompanying Figure 7 drawings:

[0028] Example one:

[0029] The present application provides a photovoltaic support suitable for slope terrain, which comprises a column assembly 1, the column assembly 1 is composed of a mounting column 101, a first column 102 and a second column 103, the mounting column 101 is installed on a slope-poured base 2, the first column 102 and the second column 103 are respectively movably arranged in the mounting column 101, and the mounting column 101 is internally provided with a height alignment assembly for adjusting the height of the first column 102 and the second column 103.

[0031] It should be noted that: by pouring the base 2 on the slope, the mounting column 101 is installed on the base 2, the first column 102 and the second column 103 are respectively installed in the mounting column 101 at different positions, the height alignment assembly is arranged in the mounting column 101 to adjust the height of the first column 102 and the second column 103, the top surfaces of the first column 102 and the second column 103 are adjusted to be consistent by the laser range finder, thereby facilitating the installation of the photovoltaic panel 6 in the later stage, so that the photovoltaic panel 6 does not need to be cut and repeatedly checked for levelness after being installed on the slope, the installation support is more flexible, and the installation efficiency of the photovoltaic panel 6 is improved.

[0032] Working principle: after pouring the base 2 at different positions of the slope and installing the mounting column 101, the first column 102 and the second column 103 are respectively inserted into the corresponding mounting column 101, the height alignment assembly is used to independently adjust the extension height of the first column 102 and the second column 103 in the mounting column 101, and a laser range finder or other tools are used to accurately adjust all the column top to the design height, usually the same horizontal plane, then the universal joint one 3, the universal joint two 4, the driving part 5 and the universal joint three 25 are installed on the column top, and finally the photovoltaic panel 6 is fixed on the universal joint one 3 and the universal joint three 25.

[0033] In this embodiment: the mounting column 101 is vertically installed on the base 2, the base 2 is poured on the slope by using concrete material, the top of each base 2 is symmetrically provided with a threaded sleeve 7, the mounting column 101 is made of steel material, the bottom of the mounting column 101 is provided with a threaded fastening part 8, and the threaded fastening part 8 is matched with the threaded sleeve 7.

[0034] It should be noted that: the concrete base 2 is directly poured on the slope, can be stably anchored in the complex terrain, provides strong anti-overturning ability, the threaded sleeve 7 embedded in the top of the base 2 can be matched with the threaded fastening part 8 at the bottom of the mounting column 101 by using a pre-buried nut or a sleeve with internal threads, and the threaded connection can be quickly and firmly achieved by rotating the mounting column 101, this connection method not only has convenient installation without on-site welding or complex fasteners, but also has strong disassembly, which is convenient for later maintenance or adjustment of the support position, and the steel mounting column 101 ensures the strength and durability of the overall structure.

[0035] Working principle: excavate the foundation pit at the selected position of the slope, place the base 2 steel reinforcement cage with symmetric threaded sleeves 7 embedded, pour concrete to form the base 2, after the base 2 solidifies, align the threaded fastening part 8 at the bottom of the mounting column 101 with the threaded sleeve 7 at the top of the base 2, rotate the mounting column 101 until it is stably screwed on the base 2, and ensure that the mounting column 101 is vertically erected on the slope surface.

[0036] In this embodiment: the top of the mounting column 101 is provided with a guide circular groove 9, the first column 102 and the second column 103 are movably installed in the guide circular groove 9, the first column 102 and the second column 103 are respectively located below the photovoltaic panel 6 and arranged along the long direction, vertical limiting holes 10 are symmetrically arranged in the guide circular groove 9, the top of the limiting hole 10 penetrates the mounting column 101 upward, the outer wall of the first column 102 and the second column 103 is symmetrically provided with a welded guide block 11, the guide block 11 is matched with the limiting hole 10, the top of the mounting column 101 is provided with a cover plate 12 for plugging the top of the limiting hole 10, and the cover plate 12 is detachably connected with the mounting column 101 by screws.

[0037] It should be noted that the guide circular groove 9 provides precise insertion guide and accommodation space for the first column 102 and the second column 103, the vertically limiting holes 10 arranged symmetrically and the guide blocks 11 welded on the outer walls of the first column 102 and the second column 103 constitute a sliding pair, so that the first column 102 and the second column 103 can only move up and down in the vertical direction within the mounting column 101, effectively preventing the first column 102 and the second column 103 from rotating or horizontally deviating during adjustment and use, and ensuring the pure linearity and stability of height adjustment.

[0038] The cover plate 12 is fixed by screws, which is convenient for disassembly. On the one hand, it closes the top of the limiting hole 10 after the first column 102 and the second column 103 are installed, preventing rainwater, dust and other foreign matters from entering the inside of the mounting column 101, protecting the internal mechanism from corrosion and pollution, and prolonging the service life. Moreover, when the cover plate 12 is removed, the first column 102 and the second column 103 can be taken out from the mounting column 101, which is better for maintenance.

[0039] Working principle: Before installation, the cover plate 12 can remain open or removed. Align the guide blocks 11 on the side walls of the first column 102 and the second column 103 with the limiting holes 10 at the top of the mounting column 101 and insert them into the guide circular groove 9, so that the guide blocks 11 are embedded in the limiting holes 10. The first column 102 and the second column 103 are lifted and lowered in the vertical direction defined by the limiting holes 10 in the guide circular groove 9 under the action of the height alignment assembly. After the installation of the first column 102 and the second column 103 is completed, the cover plate 12 is covered on the top of the mounting column 101 and fastened with screws to seal the opening at the top of the limiting hole 10.

[0040] When adjusting the height of the first column 102 and the second column 103, the operator places the laser range finder at a pre-set reference level position or fixed reference point, respectively measures the distance L1 from the laser range finder to the top of the first column 102 and the distance L2 from the laser range finder to the top of the second column 103, and adjusts the height of the first column 102 or the second column 103 by operating the corresponding height alignment assembly until L1 is equal to L2 or equal to the design value, that is, the top heights of the first column 102 and the second column 103 are consistent.

[0041] The universal joint one 3, the universal joint two 4 and the universal joint three 25 are all single-degree-of-freedom hinges, and their rotation axes are parallel to the width direction of the photovoltaic panel 6 (i.e. along the contour line direction of the slope), which enables the photovoltaic panel 6 to perform pitching rotation around the axis, and meanwhile, the universal joint two 4 and the universal joint three 25 allow the two ends of the driving member 5 to deflect at a small angle during adjustment to adapt to the change of the connection point position.

[0042] In this embodiment: the height alignment assembly comprises a vertical screw rod 13, a lifting block 14, an abutting disc 15, a bevel gear one 16 and a bevel gear two 17, the bottom of the vertical screw rod 13 is rotatably connected in the bottom of the guide circular groove 9 through a bearing, the lifting block 14 is installed on the vertical screw rod 13 through a ball nut, the lifting block 14 is fixedly connected with the ball nut, the side wall of the lifting block 14 is symmetrically provided with a vertical auxiliary plate 18, the abutting disc 15 is installed on the top of the auxiliary plate 18, and the top surface of the abutting disc 15 movably abuts against the bottom of the first vertical column 102 and the second vertical column 103.

[0043] It should be noted that: the height alignment assembly adopts a screw nut transmission mechanism, the vertical screw rod 13 is stably supported through the bottom bearing, the rotation is smooth, the lifting block 14 is fixed with the ball nut, the rotational motion of the screw rod is accurately converted into linear lifting motion, the symmetrically arranged auxiliary plates 18 enhance the structural rigidity and motion stability of the lifting block 14, the abutting disc 15 fixed on the top of the auxiliary plate 18 is directly supported on the bottom of the first vertical column 102 and the second vertical column 103, and the first vertical column 102 and the second vertical column 103 can be precisely and stably jacked up or lowered by driving the lifting block 14 to rise and fall through the rotation of the vertical screw rod 13, so that the height of the first vertical column 102 and the second vertical column 103 is steplessly adjusted.

[0044] Working principle: when the height of the first vertical column 102 and the second vertical column 103 needs to be adjusted, the vertical screw rod 13 is driven to rotate, the rotation of the vertical screw rod 13 drives the ball nut engaged therewith to move linearly, the lifting block 14 drives the abutting disc 15 to synchronously rise or fall through the auxiliary plate 18, the rising abutting disc 15 jacks up the first vertical column 102 and the second vertical column 103, so that they are raised in the vertical direction under the constraint of the guide block 11 and the limiting hole 10; the descending abutting disc 15 is lowered along with the first vertical column 102 and the second vertical column 103 under the action of the self-weight of the first vertical column 102 and the second vertical column 103, and the extension height of the first vertical column 102 and the second vertical column 103 can be accurately controlled by controlling the angle and direction of the rotation of the vertical screw rod 13.

[0047] Working principle: the externally applied rotating force drives the bevel gear two 17 to rotate around its horizontal axis, since the bevel gear two 17 is engaged with the bevel gear one 16 fixed at the bottom of the vertical screw rod 13, the rotation of the bevel gear two 17 drives the bevel gear one 16 to rotate around the vertical axis, thereby driving the vertical screw rod 13 to rotate synchronously, finally realizing the lifting movement of the lifting block 14, the first column 102 and the second column 103.

[0048] In this embodiment: the side wall of the mounting column 101 where the bevel gear two 17 extends out is provided with a directional column 19, the side away from the bevel gear two 17 of the directional column 19 is provided with a matching groove 20, the vertical cross-section profile of the matching groove 20 is "cross" shape, the matching groove 20 is provided with a rotating part 21 matched therewith, the rotating part 21 is detachably connected in the matching groove 20, the other end of the rotating part 21 is provided with a manual turntable 22.

[0050] Working principle: the present application is provided with two first columns 102 and second columns 103 at the bottom of each photovoltaic panel 6, since the first column 102 and the second column 103 are respectively located on the two sides below the photovoltaic panel 6, when the height position or angle of the photovoltaic panel 6 needs to be adjusted, the number of operators is also two, the cross end of the rotating part 21 is inserted into the cross matching groove 20 at the end of the directional column 19, two operators simultaneously rotate the manual turntable 22 clockwise or counterclockwise, drive the rotating part 21 and the directional column 19 engaged therewith to rotate synchronously, the rotation of the directional column 19 directly drives the rotation of the bevel gear two 17 connected therewith, and then drives the vertical screw rod 13 to rotate through the gear pair, realizes the height adjustment of the first column 102 or the second column 103, and keeps the change of the height of one side of the photovoltaic panel 6 and the angle adjustment.

[0051] In this embodiment: the lower half of the universal joint one 3 is detachably connected with the first column 102 by screwing, the bottom of the photovoltaic panel 6 is provided with a horizontally distributed plate 23, the horizontally distributed plate 23 is a component made of steel material, the upper half of the universal joint one 3 is rotatably connected at the bottom of the horizontally distributed plate 23 by shaft body.

[0052] It is necessary to explain that: the lower half of the universal joint 3 is detachably connected with the top of the first column 102 by screws, which is convenient for installation and maintenance. The steel plate 23 is welded on the bottom frame of the photovoltaic panel 6 to provide a firm support point. The upper half of the universal joint 3 is hinged with the bottom of the plate 23 through a shaft body (such as a pin shaft). The shaft body usually allows the upper half of the universal joint to swing in one direction (usually along the slope direction) relative to the plate 23. This connection provides the photovoltaic panel 6 with the ability to adapt to the angle in this direction, so that it can better fit the ups and downs of the slope.

[0053] In this embodiment: the longitudinal rods 24 are arranged between the plates 23. The longitudinal rods 24 are welded to the bottom of the photovoltaic panel 6. The lower half of the universal joint 4 is also installed on the top of the second vertical rod by screws. The upper half of the universal joint 4 is fixedly connected to the bottom of the driving member 5. The upper half of the universal joint 3 is also rotatably connected to the plate 23 through a shaft body. The lower half of the universal joint 3 is connected to the top of the driving member 5.

[0054] It is necessary to explain that: the longitudinal rods 24 are welded to the bottom of the photovoltaic panel 6 and constitute a stable support frame together with the plate 23. The lower half of the universal joint 4 is also detachably installed on the top of the second column 103 by screws. The driving member 5 is a hydraulic cylinder. The bottom of the cylinder body of the hydraulic cylinder is hingedly connected to the upper half of the universal joint 4 through a pin shaft. The top of the piston rod of the hydraulic cylinder is hingedly connected to the lower half of the universal joint 3 through a pin shaft. The bottom of the driving member 5 is connected to the second column 103 through the upper half of the universal joint 4, and the top is connected to the second column 103 through the lower half of the universal joint 3. The upper half of the universal joint 3 is hingedly connected to the plate 23 at the bottom of the photovoltaic panel 6 through a shaft body. The axis direction of the shaft body is usually parallel to the axis direction of the shaft body of the universal joint 1. The universal joint 4 and the universal joint 3 work together to make both ends of the driving member 5 adapt to the angle change: the universal joint 4 allows the bottom of the driving member 5 to move slightly with the second column 103, and the universal joint 3 allows the top of the driving member 5 to rotate with the hinge of the photovoltaic panel 6. The telescopic movement of the driving member 5 itself is the core power source for adjusting the inclination angle of the photovoltaic panel 6, so that the photovoltaic panel 6 can be flexibly adjusted to the best sunlight inclination angle on the slope and keep the structure stable.

[0055] Working principle: when the inclination of photovoltaic panel 6 needs to be adjusted, the drive 5 is controlled by the controller, the controller (not shown in the figure), the controller is electrically connected with the hydraulic cylinder, the controller is configured to receive instructions (such as manual input or signals from light sensor), and send control signals to the hydraulic cylinder to control the extension or retraction of its piston rod, so as to realize the adjustment of the pitch angle of photovoltaic panel 6, the controller is further configured to control the synchronous action of multiple drives 5 when multiple photovoltaic panel 6 units need to be adjusted synchronously, so as to ensure that the movement of multiple drives 5 remains synchronous, the extension and retraction movement of drive 5 is transmitted through universal joint three 25, which pushes or pulls the photovoltaic panel 6 cross plate 23 connected with it, so that the whole photovoltaic panel 6 rotates around the hinge axis of universal joint one 3, in this process, universal joint two 4 and universal joint three 25 automatically compensate the slight displacement of the connection point caused by the change of angle, ensure the smooth driving without jamming, universal joint one 3 also swings with the change of the inclination of photovoltaic panel 6, finally realize the accurate and flexible adjustment of the pitch angle of photovoltaic panel 6, more importantly, when the drive 5 moves to the maximum stroke, if the position of photovoltaic panel 6 still needs to be adjusted, the second stand column 103 can be lowered, so that the angle of photovoltaic panel 6 continues to deflect, further improve the angle adjustment range of photovoltaic panel 6.

[0056] The above only describes some exemplary embodiments of the present application by way of illustration. It is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above figures and description are illustrative in nature and should not be understood as limiting the scope of the claims of the present application.
