Description

A lattice-structured monopole photovoltaic support that can be rotated as a whole Technical Field

[0001] This invention belongs to the field of building structure technology, and specifically relates to a lattice-structured single-column photovoltaic support that can be rotated as a whole. Background Technology

[0002] In photovoltaic (PV) power generation systems, PV mounting systems are key support structures used to carry and fix PV modules. Their design directly affects the stability, installation efficiency, and power generation performance of the PV system. Existing PV mounting systems are typically fixed structures, whose core function is to reliably support PV panels over a long period at specific tilt and azimuth angles to maximize the reception of solar radiation.

[0003] Common fixed photovoltaic (PV) mounting systems mainly consist of base columns, horizontal or vertical diagonal beams, and reinforcing braces. The diagonal beams typically serve as the supporting framework for the PV panels, while the double or single columns provide vertical support and connect to the foundation. The diagonal braces enhance the overall structure's resistance to wind and deformation. This type of structure uses bolts or clamps to rigidly fix the PV panels at a pre-set angle, ensuring that their tilt angle and orientation remain fixed after installation.

[0004] However, existing fixed support structures have significant drawbacks: due to their non-adjustable structural angle, photovoltaic panels can only achieve optimal solar reception within a limited period of the day when the solar altitude angle matches the set angle of the support. In the morning, evening, or when the sun is at an angle, the angle between the incident light and the panel increases, leading to increased reflection losses and a decrease in effective power generation. This fixed reception angle cannot adaptively adjust to follow the sun's daily trajectory and seasonal changes, thus limiting the system's overall daily and annual power generation efficiency and preventing it from reaching ideal levels. Summary of the Invention

[0005] This invention provides a rotatable lattice-structure monocoque photovoltaic (PV) support, which solves the technical problem of the limitation on the power generation efficiency of PV modules caused by the structural defects of existing PV support systems. The specific technical solution is as follows: This invention provides a rotatable lattice-structure monocoque PV support, including a support body and an adjustment mechanism. The support body includes a vertical support section and a rotating shaft. A support beam arranged at an angle to the top of the vertical support section is provided. The rotating shaft is vertically inserted through the bottom of the vertical support section and fixedly connected to it. The adjustment mechanism includes a base groove, a base, and a controllable push-pull rod motor. The bottom of the vertical support section is located within the base groove. The base is located within the base groove and beside the vertical support section. The rotating shaft is rotatably connected to the base. The controllable push-pull rod motor is located inside one side wall of the base groove. The output end of the controllable push-pull rod motor is hinged to the bottom of the vertical support section via a rotating hinge. The hinge axis of the rotating hinge is parallel to the axis of the rotating shaft.

[0006] Optionally, the vertical support section includes two parallel, spaced-apart vertical arms, with a plurality of web members connecting the two vertical arms, the plurality of web members being spaced apart along the extension direction of the vertical arms.

[0007] Optionally, two adjacent web members are arranged at an obtuse angle.

[0008] Optionally, the two ends of the abdominal rod are connected to the vertical limb by bolts.

[0009] Optionally, two parallel and spaced limiting rods are also provided between the two vertical limbs, and the rotating shaft is fixedly connected between the two limiting rods.

[0010] Optionally, the top of the two vertical arms is provided with angled arms, and the supporting inclined beam is connected to the other end of the two inclined arms.

[0011] Optionally, the supporting inclined beam is bolted to the other end of the two inclined arms.

[0012] Optionally, the web member includes a box beam with a rectangular cross-section and connecting lugs disposed at both ends of the box beam, wherein bolt holes are provided on the connecting lugs.

[0013] Optionally, it also includes an automatic adjustment mechanism, which includes a cable and a tension machine and a tension sensor connected in series on the cable. The tension sensor is communicatively connected to the tension machine. The automatic adjustment mechanism is provided in two sets, and each set is connected to one end of the cable to both ends of the supporting inclined beam. The other end of the cable is vertically connected to the ground.

[0014] Optionally, the cross-section of the supporting inclined beam is cap-shaped.

[0015] Compared with existing technologies, the beneficial effects of the embodiments of the present invention include at least the following: Using the rotatable lattice-structure monocoque photovoltaic support provided in the embodiments of the present invention, the controllable push-pull rod motor, upon receiving a control signal, drives the push-pull rod to extend or shorten. The end of the push-pull rod applies a pushing or pulling force to the bottom of the vertical support section through a rotating hinge. Since the rotating shaft and the base form a rotating pair, the vertical support section rotates around the rotating shaft under the action of the pushing and pulling force, thereby driving the top support beam and the photovoltaic modules installed on it to rotate together. This rotation allows the orientation and tilt angle of the photovoltaic modules to be adjusted in real time according to changes in the sun's position, always maintaining the optimal incident angle with sunlight, significantly improving the power generation efficiency of the photovoltaic modules. This effectively solves the technical problem of the limitations on the power generation efficiency of photovoltaic modules caused by structural defects in existing photovoltaic support systems.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Figure 1 is a three-dimensional structural diagram of a rotatable lattice monocoque photovoltaic support provided in an embodiment of the present invention; Figure 2 is a front view of the rotatable lattice monocoque photovoltaic support provided in an embodiment of the present invention; Figure 3 is a front view of the rotatable lattice monocoque photovoltaic support provided in an embodiment of the present invention after rotation; Figure 4 is a three-dimensional structural diagram of another rotatable lattice monocoque photovoltaic support provided in an embodiment of the present invention; Figure 5 is a cross-sectional schematic diagram of the inclined arm provided in an embodiment of the present invention; Figure 6 is a three-dimensional structural diagram of the web member provided in an embodiment of the present invention; Figure 7 is a cross-sectional schematic diagram of the web member provided in an embodiment of the present invention; Figure 8 is a three-dimensional structural diagram of the base trench provided in an embodiment of the present invention. As shown in Figures 1 to 8, an embodiment of the present invention provides a rotatable lattice monocoque photovoltaic support, including a support body 1 and an adjustment mechanism 2.

[0020] The support body 1 includes a vertical support section 11 and a rotating shaft 12. The top of the vertical support section 11 is provided with a support inclined beam 13 arranged at an angle to the vertical support section 11. The rotating shaft 12 is vertically inserted through the bottom of the vertical support section 11 and is fixedly connected to the vertical support section 11.

[0021] The adjustment mechanism 2 includes a base 21, a base 22, and a controllable push-pull rod motor 23. The bottom of the vertical support section 11 is located inside the base 21, the base 22 is located inside the base 21 and is situated beside the vertical support section 11, the rotating shaft 12 is rotatably connected to the base 22, and the controllable push-pull rod motor 23 is located inside one side wall of the base 21. The output end of the controllable push-pull rod motor 23 is hinged to the bottom of the vertical support section 11 via a rotating hinge 24, and the hinge axis of the rotating hinge 24 is parallel to the axis of the rotating shaft 12.

[0022] In this embodiment of the invention, the support body 1 is the main structure supporting the photovoltaic modules, and it includes a vertical support section 11 and a rotating shaft 12. The vertical support section 11 is a vertically arranged lattice column structure, with its bottom extending vertically into the base trench 21 and its top extending upward to a certain height. At the top of the vertical support section 11, a support beam 13 is arranged at a certain angle to the vertical support section 11. The support beam 13 extends obliquely from the top of the vertical support section 11, forming an inclined plane suitable for the installation of photovoltaic modules. The photovoltaic panels can be fixed to the support beam 13 by clamps. The angle between the support beam 13 and the vertical support section 11 can be optimized according to the local latitude and sunlight conditions, and is usually set between 15° and 45°, so that a good sunlight reception angle can be obtained when the support is in the initial position.

[0023] The rotating shaft 12 is a key component for achieving overall rotation. It is vertically inserted into the bottom region of the vertical support section 11, and its axial direction is perpendicular to the vertical extension direction of the vertical support section 11. The rotating shaft 12 is fixedly connected to the vertical support section 11 by welding or bolting, making the rotating shaft 12 a fixed component of the vertical support section 11. Both ends of the rotating shaft 12 extend to both sides of the vertical support section 11, reaching both sides of the base groove 21.

[0024] The adjustment mechanism 2 is the power and support system that drives the rotation of the support body 1, and includes three main components: a base groove 21, a base 22, and a controllable push-pull rod motor 23. The base groove 21 is a recessed structure set in the ground foundation, and its depth is sufficient to accommodate the bottom of the vertical support section 11 and the related rotation mechanism. The bottom area of ​​the vertical support section 11 is entirely placed inside the base groove 21, which lowers the center of gravity of the entire support and enhances its stability.

[0025] The base 22 is located at the inner bottom of the foundation trench 21, on one or both sides of the vertical support section 11. The base 22 is fixedly connected to the foundation trench 21 by concrete pouring or embedded parts, forming a stable support point. The two ends of the rotating shaft 12 are rotatably connected to the corresponding base 22. This rotatable connection is achieved by providing bearing holes on the base 22, installing bearings in the bearing holes, and inserting the rotating shaft 12 into the bearings. The use of bearings allows the rotating shaft 12 to rotate smoothly relative to the base 22, while also being able to withstand the vertical loads from the support body 1 and the photovoltaic modules.

[0026] The controllable push-pull rod motor 23 is the power source for the entire adjustment mechanism. It is embedded inside one side wall of the foundation trench 21, typically located near the bottom of the vertical support section 11. The motor body of the controllable push-pull rod motor 23 is fixed to the concrete side wall of the foundation trench 21 by embedded parts. The output end of the motor is a telescopic push-pull rod, which is hinged to the bottom of the vertical support section 11 via a rotating hinge 24. The hinge axis of the rotating hinge 24 is parallel to the axis of the rotating shaft 12. This parallel arrangement ensures that the push-pull motion of the push-pull rod can be effectively converted into the rotational motion of the vertical support section 11 around the rotating shaft 12 without generating additional torsion or offset.

[0027] With the cooperation of the above structures, the controllable push-pull rod motor 23, upon receiving a control signal, drives the push-pull rod to extend or retract. The end of the push-pull rod applies a pushing or pulling force to the bottom of the vertical support section 11 through the rotating hinge 24. Since the rotating shaft 12 and the base 22 form a rotating pair, the vertical support section 11 rotates around the rotating shaft 12 under the action of the pushing and pulling force, thereby driving the top support beam 13 and the photovoltaic modules installed on it to rotate together. This rotation allows the orientation and tilt angle of the photovoltaic modules to be adjusted in real time according to the changes in the sun's position, always maintaining the optimal incident angle with sunlight, significantly improving the power generation efficiency of the photovoltaic modules.

[0028] The rotating shaft 12, connected to the base 22, provides a stable pivot point for the support body 1, ensuring the overall structure remains balanced during rotation and preventing overturning. Precise angle control is achieved through the cooperation of the controllable push-pull motor 23 and the rotating hinge 24, allowing for automatic adjustment of the support angle based on a light sensor or preset program. Compared to traditional multi-point adjustment methods, this overall rotation method is simpler in structure, easier to maintain, and ensures even stress distribution across components during rotation, resulting in a longer service life. The overall rotation of the support can follow the sun's daily trajectory, improving power generation efficiency by 15%-25% compared to fixed supports, with particularly noticeable gains during the morning and evening hours.

[0029] Referring to Figure 4, optionally, the rotatable lattice-structure monocoque photovoltaic support also includes an automatic adjustment mechanism, specifically an automatic adjustment mechanism 3. The automatic adjustment mechanism 3 includes a cable 31 and a tensioning machine 32 and a tension sensor 33 connected in series on the cable 31. The tension sensor 33 is communicatively connected to the tensioning machine 32. Two sets of automatic adjustment mechanisms 3 are provided, each connected to one end of the cable 31 to both ends of the supporting inclined beam 13, with the other end of the cable 31 vertically connected to the ground. Exemplarily, in this embodiment of the invention, when the direction of the photovoltaic panel needs to be adjusted due to varying light intensity, in addition to using a controllable push-pull rod motor 23 to push the support body 1 around the rotation axis 12 for angle adjustment, it can also be achieved through the automatic adjustment mechanism 3 additionally located between the two ends of the supporting inclined beam 13 and the ground. The tension sensor 33 detects the tension value of the two cables 31, thereby acquiring the winding and unwinding stroke of the automatically controlled tensioning machine 32. Control commands are sent from a remote control room or a nearby host computer to the tensioning machine 32 to tighten or loosen the corresponding side cable 31 to apply tension, thereby adjusting the tilt angle at both ends of the supporting inclined beam 13. By sending pre-integrated control commands to the tensioning machine 32 of the automatic adjustment mechanism 3 on both sides according to a preset timing, the orientation and tilt angle of the photovoltaic modules can be automatically controlled, further improving practicality.

[0030] Optionally, the vertical support section 11 includes two parallel, spaced-apart vertical arms 111, with multiple web members 112 connecting the two vertical arms 111. The web members 112 are spaced apart along the extension direction of the vertical arms 111. Exemplarily, in this embodiment of the invention, based on the above embodiments, to effectively reduce the self-weight of the support and lower material costs while ensuring load-bearing capacity, the vertical support section 11 preferably adopts a lattice column structure. The two vertical arms 111, as the main load-bearing components of the lattice column, extend along the vertical direction of the vertical support section 11, and their spacing is determined according to the load-bearing and stability requirements of the support, typically set to 300mm to 800mm. The vertical arms 111 can be made of angle steel, channel steel, or square tubing, preferably equilateral angle steel or square tubing, to facilitate the connection of the web members 112. The bottom end of the vertical arm 111 extends into the base groove 21 and connects to the rotating shaft 12; the top end extends upward to a set height and connects to the inclined arm 114. Multiple web members 112 are arranged at intervals along the extension direction of the vertical arms 111, connecting two vertical arms 111 into a whole lattice structure. The number of web members 112 is determined according to the height of the vertical support section 11, and is usually one web member 112 every 600mm to 1000mm. The two ends of the web members 112 are connected to the two vertical arms 111 respectively, so that the two vertical arms 111 form a stable connection and jointly bear the load from the photovoltaic modules as well as external forces such as wind load and snow load.

[0031] Under the same load-bearing capacity, the self-weight of the lattice column is only 60%-70% of that of the solid column, which effectively reduces the overall weight of the support, reduces the load requirements on the foundation, and also reduces the driving power requirements of the rotating mechanism. The open structure of the lattice column allows wind loads to partially pass through the support, reducing the effect of wind loads and improving the wind resistance of the structure.

[0032] Optionally, adjacent web members 112 are arranged at an obtuse angle. Exemplarily, in an embodiment of the invention, as shown in Figures 1 and 2, viewed from the side of the vertical support section 11, multiple web members 112 are arranged sequentially along the height direction of the vertical limbs 111. The first web member 112 extends obliquely upward from the lower left connection point of the vertical limb 111 to the connection point of the right vertical limb 111; the second web member 112 extends obliquely upward from the connection point of the right vertical limb 111 to the connection point of the left vertical limb 111, and so on, alternating between the two. The included angle formed between adjacent web members 112 is an obtuse angle, typically set to 100° to 150°, preferably 120° to 135°. The obliquely arranged web members 112 not only bear axial forces but also effectively resist shear forces, significantly improving the overall stiffness of the lattice column, especially its lateral stiffness in the horizontal direction.

[0033] Optionally, the two ends of the web member 112 are bolted to the vertical arm 111. Exemplarily, in this embodiment of the invention, to facilitate on-site assembly, maintenance, and possible disassembly of the lattice column, the two ends of the web member 112 are bolted to the vertical arm 111. This connection method involves providing connecting lugs at both ends of the web member 112 and connecting plates at corresponding positions on the vertical arm 111, or utilizing the flanges of the vertical arm 111 itself, to fix the web member 112 to the vertical arm 111 with bolts. Using bolted connections eliminates the need for welding equipment during on-site assembly, resulting in faster construction speeds, easier quality control, and immunity to weather conditions. Bolted connections are also detachable, facilitating later maintenance and repair. If a damaged web member 112 needs replacement or structural adjustments are required, only the bolts need to be removed, eliminating the need for cutting and re-welding. For the batch construction of large-scale photovoltaic power plants, bolted connections offer a high degree of standardization, enabling factory prefabrication and rapid on-site assembly, significantly shortening the construction period and reducing overall costs.

[0034] Optionally, two parallel, spaced-apart limiting rods 113 are further provided between the two vertical arms 111, and the rotating shaft 12 is fixedly connected between the two limiting rods 113. Exemplarily, in this embodiment of the invention, to enhance the stability of the connection between the rotating shaft 12 and the vertical support section 11 and the synchronization of rotation, two parallel, spaced-apart limiting rods 113 are further provided between the two vertical arms 111. The two ends of the two limiting rods 113 are respectively welded or bolted to the two vertical arms 111, making the two limiting rods 113 transverse members connecting the two vertical arms 111. The rotating shaft 12 passes between the two limiting rods 113, and the rotating shaft 12 is fixedly connected between the two limiting rods 113 by welding, clamping, or bolting. Specifically, a connecting plate or reinforcing plate can be installed between the two limiting rods 113, and the rotating shaft 12 can be welded or fixed to the connecting plate, or the middle part of the rotating shaft 12 can be directly welded between the two limiting rods 113. The two limiting rods 113 form a stable frame structure, providing a reliable fixed foundation for the rotating shaft 12 and ensuring that the rotating shaft 12 will not bend or displace due to load. The presence of the limiting rods 113 significantly improves the rigidity of the bottom of the vertical support section 11. When the support rotates, the two vertical arms 111 can rotate synchronously without relative misalignment. When the push-pull rod motor 23 pushes the vertical support section 11 to rotate, the limiting rods 113 can effectively resist the local bending caused by the deviation of the point of application of the thrust from the rotation axis, protect the vertical arms 111 from plastic deformation, and extend their service life.

[0035] Optionally, the tops of the two vertical arms 111 are provided with angled inclined arms 114, and the supporting inclined beam 13 is connected to the other ends of the two inclined arms 114. Exemplarily, in this embodiment of the invention, to achieve a smooth transition from the vertical support section 11 to the inclined supporting inclined beam 13 and to provide a stable installation foundation, the tops of the two vertical arms 111 are respectively provided with angled inclined arms 114. The inclined arms 114 extend obliquely upwards or forwards from the top of the vertical arms 111, forming an inclination angle with the vertical arms 111, which typically corresponds to the desired photovoltaic module installation tilt angle. The starting ends of the two inclined arms 114 are respectively connected to the tops of the two vertical arms 111, and the connection method can be welding or bolting. The extending direction of the inclined arms 114 forms a certain angle with the vertical arms 111, which is determined according to the installation tilt angle requirements of the photovoltaic module. The other end of the inclined arm 114 (the end away from the vertical arm 111) is used to connect to the support inclined beam 13, thereby supporting the support inclined beam 13 in the desired inclined position.

[0036] The inclined arm 114 can use the same profile specifications as the vertical arm 111, or a slightly smaller profile can be selected depending on the stress conditions. In order to enhance the strength of the connection between the inclined arm 114 and the vertical arm 111, a reinforcing rib plate is usually set at the connection or double-sided welding is used to ensure that the connection node can withstand the bending moment and shear force from the supporting inclined beam 13 and the photovoltaic module.

[0037] Optionally, the web member 112 includes a box beam 1121 with a rectangular cross-section and connecting lugs 1122 disposed at both ends of the box beam 1121. Bolt holes 1123 are provided on the connecting lugs 1122. Exemplarily, in this embodiment of the invention, to meet the load-bearing requirements of the lattice column and facilitate bolt connection with the vertical arms 111, the web member 112 adopts a composite structure. The box beam 1121 is the main body of the web member 112, which is made of square or rectangular steel tubing, with the four sides of the tubing forming a closed rectangular cross-section. The length of the box beam 1121 is determined according to the distance between the two vertical arms 111 and the arrangement angle of the web member 112. The connecting lugs 1122 are welded to both ends of the box beam 1121, with one or a pair of lugs provided at each end. The connecting lugs 1122 are made of steel plate to withstand the concentrated force transmitted by the bolts. The connecting ear plate 1122 has bolt holes 1123. The number, diameter and spacing of the bolt holes 1123 are designed according to the connection strength requirements.

[0038] The closed section of the box girder 1121 has high torsional stiffness and bending stiffness. Under the same material usage, its load-bearing capacity is better than that of open sections (such as angle steel and channel steel), making it particularly suitable for bearing combined compression and bending. The setting of the connecting ear plate 1122 strengthens the concentrated force area and avoids local deformation or damage caused by the bolts acting directly on the thin wall of the box girder 1121.

[0039] Optionally, the cross-section of the supporting inclined beam 13 is hat-shaped. Exemplarily, in this embodiment of the invention, the cross-section of the supporting inclined beam 13 is hat-shaped, an optimized cross-sectional form specifically designed for photovoltaic module installation. The hat-shaped cross-section, viewed from the side, resembles an inverted hat, having a downward-opening U-shaped or C-shaped body and two outward-folding edge flanges. Specifically, the top of the hat-shaped cross-section is a flat web, with the two sides of the web bending downwards to form two sidewalls, the lower ends of which then fold outwards to form horizontal or slightly upward-sloping flanges. The entire cross-section thus forms a structure with a hollow center and flanges on both sides. This cross-section can be processed from steel plate or strip using a cold-bending forming process, or it can be mass-produced using roll forming.

[0040] The downward-facing opening of the hat-shaped cross-section allows components such as guide rails and crossbeams for photovoltaic module installation to be easily inserted into or overlapped on the flange of the hat-shaped beam, making the installation method flexible and diverse. The shape of the hat-shaped cross-section gives it a large moment of inertia and modulus, resulting in excellent bending performance. It is not prone to excessive deflection when bearing the weight of photovoltaic modules and wind and snow loads.

[0041] Optionally, both the vertical support section 11 and the supporting inclined beam 13 are steel structural components. Exemplarily, in this embodiment of the invention, both the vertical support section 11 and the supporting inclined beam 13 are steel structural components, meaning that steel is used as the manufacturing material. The steel used here includes, but is not limited to, carbon structural steel (such as Q235, Q345), low-alloy high-strength structural steel (such as Q355, Q420), and weathering steel.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
