Description

AREA

[0001] The present application relates to the technical field of photovoltaic power generation, in particular a support frame for photovoltaic arrangements and a photovoltaic power generation system. BACKGROUND

[0002] In a photovoltaic power generation system, the mounting system for photovoltaic modules is used for installation and securing the modules and has a significant impact on the system's lifespan and power generation efficiency. Mounting systems for photovoltaic modules can be divided into tracking systems and fixed systems. Tracking systems can adjust their angle according to changes in the angle of incidence of sunlight and generally achieve higher power generation yields compared to fixed systems.

[0003] Conventional tracking support frames for photovoltaic arrays, for example a tracking support frame disclosed in publication WO2014093258A1, generally comprise a plurality of columns 1', and a torque tube 2' is provided between two adjacent columns 1', i.e. a total of N columns 1' and N-1 torque tubes 2' (see Fig. Figure 1 shows the 11 columns and 10 torque tubes). The torque tube 2' serves to support and drive the photovoltaic arrays in order to rotate them. Between these N-1 torque tubes 2', two adjacent torque tubes 2' must be firmly connected to each other via structural fasteners 3', thereby fixing and connecting the N-1 torque tubes 2' into a single unit and achieving sun tracking through a holistic rotation.

[0004] This structure has at least the following disadvantages: The torque tubes are connected to form a rigid, long shaft, and in the event of external disturbances, such as wind disturbances, especially strong winds, a large lateral external force can be rigidly transmitted to the columns. If the strength of the column or the base on which the column is mounted is insufficient, the tracking support frame can deform or even bend. To ensure that such tracking support frames are stable in bad weather, the column and its mounting base (if present) must have high strength, which results in high material consumption.

[0005] Similarly, conventional fixed frames for photovoltaic arrays also require high strength of the column or mounting base to ensure the stability of the photovoltaic systems.

[0006] For these reasons, the material costs for the column or mounting base of the tracking support frame and the fixed frame are high. Furthermore, due to the high demands on reinforcement and stability, as well as the complex structure of the components, extensive on-site construction and assembly work is required, which complicates installation and results in high installation and reinforcement costs.

[0007] Although the aforementioned disadvantages have existed for a long time and a solution to these problems is desired in the industry, the solution to these problems has not been significantly advanced so far due to the limitations imposed by cost factors. FORMS OF EXECUTION OF THE INVENTION

DETAILED DESCRIPTION OF THE DRAWINGS

[0108] To better explain the technical solutions and advantages of the embodiments of this disclosure, the embodiments of this disclosure and the associated technical content are explained in more detail below with reference to the accompanying drawings and the written description. It is understood that the embodiments described below serve only to illustrate the technical solutions of the embodiments of this disclosure and do not limit the scope of protection of this disclosure. The drawings are not necessarily to scale; some elements or configurations of elements may be exaggerated or simplified to better explain this disclosure.

[0109] It is noted that the terms "first," "second," and the like, as used herein, serve solely to distinguish one thing, state, or action from another, without necessarily indicating or implying any relative significance or order. The terms "includes," "comprehensive," or other variants thereof are intended to cover non-exclusive inclusion, and the inclusion may not be limited to the objects mentioned herein. The term "multiple" or other variants are used to indicate that the number of objects is two or more.

[0110] In a first aspect, some embodiments of the present disclosure offer a support frame for photovoltaic arrangements comprising upright elements, a support arrangement, a connecting element and a tension element.

[0111] Photovoltaic systems are configured to convert light energy into electrical energy, and their specific configuration can vary. Generally, photovoltaic systems take the form of solar modules. Common solar modules include glass, adhesive films, battery modules, backsheet modules, and frames. Of course, in other application scenarios, photovoltaic systems can also consist of solar cells and their accessories in other shapes or structures.

[0112] The uprights serve to maintain the support structure at the required working height during operation of the photovoltaic array support frame. Typically, the uprights can be positioned on the ground, on hills, on bodies of water, on buildings, on foundations, on platforms, on columns, or on other types of foundations, ensuring the support structure maintains a vertical distance from these structures. For example, the uprights can hold the support structure at a specific height above the ground, water surface, etc. Maintaining a specific working height is advantageous for optimizing the absorption of light energy by the photovoltaic components. For instance, a required tilt angle for the photovoltaic arrays can be achieved, or the amount of light obstructions to the arrays can be reduced.

[0113] At least two upright elements are connected to a support structure. In practice, there can of course be more upright elements. The distance between adjacent upright elements can be determined according to the actual requirements of the installation structure, such as the size of the photovoltaic arrays and the size of the support structure, and is not particularly limited.

[0114] The columns can be made of metal, wood, concrete, or another material. One of these configurations is in Fig. The support frame 100 for photovoltaic arrays comprises upright elements (columns) 1, a support assembly 300 consisting of a support beam 2 and support rods 3, and a connecting element 200. The photovoltaic arrays 4 are positioned on the support assembly 300. The support frame 100 further comprises: an arc-shaped bracket 5, a tension cable 6, and a mounting bracket 10, with a motor 9 attached to the mounting bracket 10.

[0115] In some embodiments, the upright elements 1 can be designed as a single-piece element. For example, an upright element can be a column.

[0116] In other embodiments, the upright elements 1 can be designed as a multi-part element. For example, the upright elements 1 can comprise a base and a column arranged on the base. Alternatively, the base can utilize a cement column, a screw pile, or the like to reinforce and stabilize a main body of the column, which may be a metal column arranged on these bodies.

[0117] The cross-section of the upright elements 1 can be circular, square, other regular or irregular shapes and is not particularly limited in this respect.

[0118] Furthermore, the angle of inclination of the upright elements 1 with respect to the base need not be particularly restricted. For example, the upright elements 1 need not necessarily be at an angle of 90 degrees or close to 90 degrees to the surface of the base. In particular, on level ground, the upright elements 1 may have a different angle of inclination than on sloping hillsides. The person skilled in the art may appropriately select the angle of inclination of the upright elements, taking into account various factors such as the physical properties of the upright elements, the actual terrain, the installation requirements of the main base body, or the local solar radiation conditions.

[0119] The upright elements 1 have a connection end for connecting to the connection element 200. The configuration of the connection end can depend on the configuration of the connection element 200, as long as it matches the configuration of the connection element 200.

[0120] In some embodiments, the upright elements 1 may have additional parts besides the connection end to the connecting element 200. For example, the upright elements 1 may also have a fastening section to raise and hold the support arrangement 300 at a desired mounting height, thus facilitating the assembly of the relative parts of the support frame 100 for the photovoltaic arrangements 4. Alternatively, the fastening section may use a suspension structure or a support structure. For example, the suspension structure may be a hanger, such as a hook or loop, that suspends the support arrangement to hold it at a desired mounting height. The support structure may be a support table, a support column, or the like, which supports the support arrangement to hold it at a desired mounting height.The assembly at this mounting height includes, among other things, the assembly of the components of the support assembly 300 itself, the assembly of the support assembly 300 with the photovoltaic assemblies 4, or the assembly of the support assembly with other components. Alternatively, the fastening section can be detachably connected to the main body of the upright elements 1, or the fastening section can be welded to the main body of the upright elements 1, or the fastening section can be integrally formed with the main body of the upright elements 1.

[0121] The support structure 300 serves to support the photovoltaic arrays 4. Depending on the actual requirements, a support structure 300 can support only one photovoltaic array 4 or two or more photovoltaic arrays 4. The arrangement of the photovoltaic arrays 4 supported by the support structure 300 can vary. For example, the photovoltaic arrays can be arranged in one or more rows, and adjacent photovoltaic arrays can have gaps or be closely connected. In addition, some parts of the support structure 300 can be located below or to the side of the photovoltaic modules 4.

[0122] The support structure 300 can have a variety of configurations depending on the actual requirements. The support structure 300 can be a single element, such as a support plate, a support frame, or a support beam. In this case, the photovoltaic arrays 4 can have a structure that is rigidly connected to them. The support structure 300 can also be a combination of several individual structural elements, such as a combination of a main beam and purlins, a combination of a support plate and several support rods, or a combination of a frame and support rods.

[0123] In some embodiments, the support arrangement 300 comprises at least one of the following support elements or a combination of at least one of the following: support beams, support rods, support plates, or support frames. The support beams, support plates, or support frames serve as the main load-bearing structures on which the support rods may be provided or which may extend outwards on the basis of these load-bearing structures. For example, the support arrangement 300 may, as is common, comprise a main beam and a plurality of support rods, which are referred to as purlins. Of course, in some cases, the support arrangement 300 may be formed from a plurality of support rods without a support beam or the like. For example, a plurality of support rods may be arranged to form a square or net-shaped support frame.

[0124] In some embodiments, at least two ends of at least one support element are each movably connected to a respective upright element 1 by a respective connecting element. For example, if the support arrangement comprises a support beam, the two ends of the support beam can each be movably connected to the two upright elements 1. If the support arrangement 300 comprises, for example, a support frame, two positions can be selected as two end sections on the support frame, and the two ends can each be movably connected to the two upright elements 1. Of course, in some cases, three or more ends of the support element can be movably connected to the upright elements 1, and there is no particular limitation.

[0125] In some embodiments, the support arrangement comprises 300, as in Fig. Figure 3 shows a support beam 2 and several support rods 3 arranged along a longitudinal direction or longitudinal axis of the support beam 2. Alternatively, the support rods 3 can be arranged parallel to each other, with the longitudinal direction or longitudinal orientation of the support rods 3 being substantially orthogonal to the longitudinal direction or longitudinal orientation of the support beam 2.

[0126] The support beam 2 serves to support a multitude of support rods 3, and the multitude of support rods 3 serves to support the photovoltaic arrangements 4.

[0127] The two ends of the support beam 2 are movably connected to the respective upright elements 1 via the respective connecting elements 260 and 270. For example, in Fig. 3 the left end of the support beam 2 on the left side is movably connected to the upright element 1 on the left side via a connecting element 260, and the right end of the support beam 2 on the right side is movably connected to the upright element 1 on the right side via a connecting element 270.

[0128] In some embodiments, the support arrangement 300, as in Fig. Figure 4 shows a support frame 450. A first end 451 and a second end 452 of the support frame 450 are each movably connected to the upright elements 1 on both sides.

[0129] Here, the support structure 300 and the object it supports can be collectively referred to as a photovoltaic module. Therefore, in some cases, the support structure 300 and the photovoltaic assemblies 4 can constitute a photovoltaic module, or the support structure 300 and the photovoltaic assemblies 4 can form a major part of the photovoltaic module. The photovoltaic module can also include fastening elements such as struts, strut connectors, strut stiffeners, or the like, which are provided on the support structure 300 and / or the photovoltaic assemblies 4.

[0130] The support assembly 300 can include a rotating shaft to rotatably support the photovoltaic arrays. In some cases, the drive mechanism can drive the rotating shaft directly or indirectly to adjust the tilt angle of the support assembly 300 and thus drive the tilt angle of the photovoltaic arrays 4, so that the support frame 100 can serve as a tracking support frame for the photovoltaic arrays 4.

[0131] Naturally, the support arrangement 300 cannot have a rotating shaft for rotating the photovoltaic arrangements 4. In some cases, the support frame 100 for the photovoltaic arrangements 4 cannot be driven by the drive mechanism to follow the sunlight and thus cannot serve as a fixed support frame.

[0132] Therefore, in some embodiments, the support arrangement 300 can rotate to follow the sun's movement. In other embodiments, the support arrangement 300 is not rotatable, and the support frame 100 for the photovoltaic arrays can be used as a fixed support frame. Naturally, the support arrangement 300 may sway slightly due to external forces (such as wind power), which is permissible.

[0133] The connecting element serves to movably connect the support assembly 300 to the upright element 1. In practice, at least two connecting elements movably connect two ends of the support assembly 300 to the respective upright element 1.

[0134] The term "movable connection" refers to a connection that allows the support arrangement 300 to move in two or more degrees of freedom within a certain range relative to the upright elements 1 when the support arrangement 300 is subjected to an external force. Thus, in some embodiments, some connecting elements may be movably connected to the support arrangement 300. In some embodiments, some connecting elements may be movably connected to the upright elements 1. Alternatively, in some embodiments, some of the connecting elements are movably connected to the support arrangement 300 or to the upright elements 1.

[0135] The aforementioned external force includes, among other things, wind force, force transmitted by the photovoltaic arrays 4, or force transmitted by the drive mechanism. Regardless of whether the support arrangement 300 can be rotated or not, the aforementioned specific range of motion includes the oscillation of the support arrangement 300 under the external force. Thus, the term "movable connection" or "movably connecting" can refer to a connection that allows the connected objects to oscillate.

[0136] Of course, the term "movable connection" or "movable connection" can also refer to a flexible connection between rigid objects in some cases. In this case, the term "flexible connection" can refer to a connection that allows the connecting section to expand and contract axially and to generate a certain displacement in the vertical axial direction.

[0137] In some conventional solutions, a rigid connection is used between the main beam, which is a horizontal uniaxial tracker, and the columns. For example, the main beam is welded or clamped to the column and cannot be moved; or the main beam can only rotate about its axis under the drive of the motor. The rigid connection in the conventional technical schemes means that the main beam can only move in one degree of freedom when rotating about its axis. In contrast to these rigid connections, the movable connection provided by the disclosed embodiments allows the support arrangement 300 to move in a range of degrees of freedom relative to the upright elements 1.

[0138] The term "degrees of freedom" used here refers to the degrees of freedom of motion of a rigid body in three-dimensional space. A rigid body in three-dimensional space has a total of six degrees of freedom: three translational degrees of freedom and three rotational degrees of freedom. The X-axis, Y-axis, and Z-axis are considered three coordinate axes in a Cartesian rectangular coordinate system and move in six degrees of freedom, including rotation about the X-axis, Y-axis, and Z-axis, and translation about the X-axis, Y-axis, and Z-axis.

[0139] In some embodiments, the movable connection of the support arrangement 300 allows it to move in six degrees of freedom. As in Fig. As shown in Figure 2, the support arrangement 300 can be driven by a drive mechanism to rotate about the X-axis. Furthermore, rotation about the Y-axis or about the Z-axis can be effected to a very small extent by an external force, and movement can also occur to a small extent in the X-axis, Y-axis, or Z-axis direction, with these small rotations and movements being limited in scope.

[0140] In some embodiments, the movable connection allows a first connecting end 201 of the connecting element 200, which is connected to the upright elements 1, to move in several degrees of freedom. As in Fig. As shown in Figure 5, the first connecting end 201 of the connecting element 200 is connected to the upright elements 1, and the first connecting end 201 can move in several degrees of freedom.

[0141] In some embodiments, the movable connection allows a second connecting end 202 of the connecting element 200, which is connected to the support arrangement 300, to move in several degrees of freedom. As in Fig. As shown in Figure 5, the second connecting end 202 of the connecting element is connected to the support arrangement 300, and the second connecting end 202 is movable in several degrees of freedom.

[0142] The movable connection enables the support arrangement 300 to move within a range of motion under the influence of an external force from nature, the range of motion being limited to an area in which the support arrangement 300 does not easily collide with the upright elements 1 due to the external force and does not easily generate an unexpected and large vibration at the inclination angle of the support arrangement 300.

[0143] The movable connection has the advantageous effect that, if the photovoltaic arrays 4 or the support structure 300 are disturbed by an external force (e.g., wind force in strong winds), the disturbance is no longer necessarily and rigidly transmitted to the vertical element in several degrees of freedom. The disturbance force absorbed by the photovoltaic module or the support structure 300 can be buffered and then transmitted to the upright elements 1. In some cases, the movable connection increases the time required for force transmission, thus slowing down the impact force. In some cases, the movable connection allows for a change in the force transmission angle of the support structure 300, thereby eliminating part of the impact force. Furthermore, the movable connection also allows some of the shocks to which the upright element 1 is subjected to to be transmitted non-rigidly to the support structure 300.The movable connection allows for a degree of self-balancing of the support structure 300, the upright elements 1, and even the entire support frame 100 of the photovoltaic arrays 4 under external influence. Therefore, the requirements for the mechanical strength of the support frame 100 for photovoltaic arrays, such as wind resistance, earthquake resistance, and the like, are reduced. This reduces the material and cost expenditure for the construction of the columns and facilitates the normal operation of the support frame 100 in various harsh environments such as strong storms, rain, snow, and earthquakes.

[0144] The range of motion and the number of degrees of freedom of the relative movement corresponding to the movable connection can be freely chosen according to the actual requirements of the user, depending on the structure of the connecting element and the type of connection of the connecting element 200 and the support arrangement 300 or the upright elements 1.

[0145] The configuration of the connecting element 200 can be varied to achieve the movable connection. For example, the connecting element 200 can comprise at least one of the following connecting elements or a combination of at least one of the following connecting elements: a loop element, wherein at least one loop element is connected to the support arrangement 300 or the upright elements 1; a hook element, wherein at least one hook element is connected to the support arrangement 300 or the upright elements 1; and a chain or rope, at least one end of which is connected to the support arrangement 300 or the upright elements 1.

[0146] The Fig. show some alternative configurations of the connector 200. As in Fig. As shown, the connecting element 200 uses the loop element 12 and the hook element 13. The loop element 12 is matched to the hook element 13, allowing the support assembly 300 not only to rotate about the axis of rotation but also to move left and right within a certain range along the direction of the axis of rotation or to oscillate in multiple directions. During solar radiation tracking, the influence of resonance and lateral shear forces generated by the existing rigid connecting structure is partially eliminated or reduced under windy conditions, thereby simplifying the upright elements 1 and the associated structure and reducing material consumption.

[0147] In Fig. 6 the connecting element 200 is designed as rope 14. Alternatively, the rope can be designed as a wire rope, wire cable, chain or the like.

[0148] In some embodiments, the loop element can comprise a closed metal loop or a metal loop with a notch. The hook element can comprise a metal hook. Alternatively, the metal hanger can also be connected to the support arrangement 300 via a pulley and a loop. Furthermore, the loop element can comprise a closed or notched composite loop made of two or more materials, for example, a metal material, a ceramic material, or a polymer material. Additionally, the hook element can comprise a composite hook made of two or more materials, for example, a metal material, a ceramic material, or a polymer material.

[0149] In some embodiments, such as in Fig. As shown in Figure 7B, the connecting element 200 comprises a lifting ring 210, a bearing arrangement 220, and an interface shaft 230, which is supported by the bearing arrangement 220. The lifting ring 210 has a first end that is movably connected to a connecting end 1010 of the upright elements 1, and a second end that is movably connected to the bearing arrangement 220. The first end is higher than the second end. One end of the interface shaft 230 is connected to the support arrangement 300.

[0150] In some possible cases, the first end of the lifting ring 210 is movably connected to the connecting end of the upright elements 1 by suspending the first end of the lifting ring 210 from a loop element or hook element provided on the upright elements 1. The second end of the lifting ring is movably connected to the bearing assembly, including, but not limited to, a hinge connection, or the top of the bearing assembly 220 is movably suspended from the second end of the lifting ring 210. The interface shaft serves to connect the support assembly 300, and one end of the rotating interface shaft 230 can be screwed or bolted to one end of the support assembly 300. Of course, other connecting means can also be used.After the interface shaft 230 is connected to the support arrangement 300, the support arrangement 300 can rotate due to the screw connection between the interface shaft 230 and the bearing arrangement 220.

[0151] At this point, the lifting ring 210, the bearing assembly 220, and the interface shaft 230 together form a universal lifting ring. The universal lifting ring can be rotated 360 degrees (universally), is suitable for lateral lifting, is flexible in its application, and has a high safety factor.

[0152] In some embodiments, the connecting element 200 is detachably connected to the support arrangement 300. In other embodiments, the connecting element 200 can be detachably attached to the upright elements 1. Of course, the connecting element 200 can also be permanently connected to the support arrangement 300 or the upright elements 1. In this case, it is only necessary to ensure that the components of the connecting element 200 can be movably connected to one another or that the support arrangement 300 can be movably connected to the upright elements 1.

[0153] To achieve the movable connection, the connecting element 200 can also include rigid elements. For example, the aforementioned connecting component can be rigid. Of course, in other cases, parts of the connecting element 200 can be rigid and other parts can be flexible.

[0154] To achieve the movable connection, the connecting element 200 can also be a lifting rod, at least one end of which is movably connected to the support arrangement 300 or the upright elements 1.

[0155] Of course, the connecting element 200 can also assume other configurations (e.g. the configuration of the double-bore bushing mentioned below) and is not particularly limited in this respect.

[0156] In some embodiments, such as in Fig. As shown in Figure 8, the connecting element 200 can also include other configurations. For example, the connecting element 200 can include the wire clamp 203, the pull rod 204, the adjusting screw 205, or the like, as shown in Figure 8. Fig. 8 shown.

[0157] A tension element for exerting a lateral tensile force on the support arrangement 300 in order to stabilize the support arrangement 300. If the support arrangement 300 has an axis of rotation, the "lateral direction" may refer to a direction that is not parallel to, and in particular substantially perpendicular to, an axial direction of the axis of rotation of the support arrangement 300. For example, the axial direction in Fig. 2 marked with “X”. If there is a first connection point where one end of the support arrangement 300 is connected to one of the connecting elements 200, and a second connection point where the other end of the support arrangement 300 is connected to the other connecting element 200, the “lateral direction” may also refer to a direction that is not parallel to, in particular substantially perpendicular to, a straight line connecting the first and second connection points. In particular, the direction of the tensile force does not completely overlap with the direction of gravity. In summary, the specific direction to which “lateral direction” refers serves to stabilize the support arrangement 300.

[0158] The tensile force can refer to a force that generates or corresponds to a tensile effect. The tensile element can stabilize the center of gravity of the support arrangement 300 or the inclination of the support arrangement 300 by exerting a lateral tensile force.

[0159] The Fig. 21, Fig. 22 and Fig. Figure 23 shows the direction (i.e., the lateral direction) of some possible tensile forces. In the Fig. 21, Fig. 22 and Fig. The support arrangement 300 comprises a support beam 2 and support rods 3. The photovoltaic assemblies 4 are fixedly attached to the support rods 3. In the illustrations, the center of gravity of the photovoltaic module is marked with the reference number 410. The lateral direction 21, i.e., the direction of the tensile force, can be the direction from the space on both sides of the center of gravity 410 to the ground 20. For example, the spaces on both sides comprise the lateral spaces 22 shown.

[0160] In the case of the support arrangement 300 with the rotating shaft 400, the tension element is used to exert a tensile force on one or both sides of the rotating shaft of the support arrangement 300 in order to stabilize and / or adjust the support arrangement 300. An example is shown in Fig. Figure 9B shows a first tension element 401 positioned on a first side of the rotary shaft 400 and a second tension element 402 positioned on a second side of the rotary shaft 400.

[0161] Fig. Figure 9C shows further locations where tension elements 401 and 402 are attached. Fig. 9C is the first end of the support arrangement 300 connected to the connecting element 200 on two sides of the connection point and connected to the first tension element 401 and the second tension element 402.

[0162] As in the Fig. As shown in Figures 9A-9C, the tension elements 401, 402 can be attached directly to the support element. Of course, in other embodiments, the tension element can be connected to other elements provided on the support element.

[0163] In the embodiments described in the present disclosure, the tension element, in addition to the connecting element, is an important part that limits the range of motion of the support arrangement 300. The tension element can interact with the connecting element 200 to stabilize the inclination angle of the support arrangement 300. The term "stable" here does not mean that the inclination angle is absolutely constant, but rather that the support arrangement is secured within a range of motion to prevent frequent, large fluctuations in the inclination angle.

[0164] The pulling element can be a cable, a chain, or any combination thereof. The cable can be made of various materials and with different weaves; for example, a stainless steel cable or a composite cable can be used. Naturally, the pulling element can also have other configurations. In some embodiments, the pulling element can be either a cable or a chain.

[0165] In some embodiments, at least one end of the pulling element can be provided with a shock absorber.

[0166] In some embodiments, the length of the pulling element is adjustable. In particular, a mechanism may be provided to receive and release the pulling element, thereby adjusting its length. The pulling rope, chain, or strap can be stored by winding it up or released by reversing the winding direction, thus changing the length. Of course, a person skilled in the art can also adjust the length of the pulling element by using other mechanisms commonly used in engineering or mechanical engineering for storing and releasing ropes, chains, etc.

[0167] In some embodiments, a first end of the tension element provides tension to the support arrangement 300, and a second end of the tension element is adjustable in its position. For example, the second end of the tension element can be attached to a different location on the ground or to a different foundation body, thereby changing the inclination angle of the support arrangement 300. Alternatively, the second end of the tension element can be attached to a movable mechanical structure to adjust the position of the second end of the tension element. Such a mechanical structure includes, among other things, a mechanical arm with a linear stroke, a push rod, and a sliding block on a slide rail.

[0168] Of course, the first end of the tension element can be attached in a similar manner at a different position, thereby changing the inclination angle of the support arrangement 300. For example, the support element can be provided with a variety of attachment points for the first end of the tension element.

[0169] In some alternative embodiments, the inclination angle of the support arrangement 300 and thus the inclination angle of the photovoltaic arrangements can be changed by adjusting the length of the first tension element and the length of the second tension element.

[0170] In some embodiments, the length of the tension element is not adjustable. For example, the tension element is a fixed-length rope, and the position of the attachment points at the ends of the rope is not adjustable. Alternatively, the first end of the tension element exerts the tensile force on the support arrangement 300, and the second end is anchored at a fixed point.

[0171] It should be noted that the length of the tensioning element is not adjustable; however, this does not mean that the length of the tensioning element is absolutely constant in actual application. In fact, the length of the tensioning element can vary or change very slightly due to changes in the tensile force.

[0172] According to the overall description of the upright elements, the support arrangement, the connecting elements, and the tensioning elements, the support arrangement for the photovoltaic arrays provided by the embodiments of the present disclosure can pull the support arrangement to rotate it when the tilt angle of the photovoltaic arrays needs to be adjusted, since the upright elements are movably connected to the support arrangement, thus fulfilling the requirement of tracking solar irradiance in some scenarios. In some scenarios, the support frame can be used as a fixed support frame without adaptation to a drive mechanism.

[0173] The upright elements 1 are movably connected to the support arrangement 300. The frictional force provided by the respective structure can generate a damping effect, and the movable connection allows the support arrangement 300 to move in multiple degrees of freedom. This eliminates or reduces the influence of resonance and lateral shear forces on the upright elements 1 under windy conditions. Most external forces or disturbances that act on the photovoltaic arrays or the support arrangement 300 in practice do not need to be rigidly transmitted to the upright elements 1, and their effects are reduced and buffered. Based on this, the upright elements 1 can be lightweight and miniaturized, resulting in significant material and cost savings.

[0174] The support structure for photovoltaic arrays provided in the embodiments of the present disclosure can be used in a large-scale photovoltaic power generation system. Since the adjacent support arrangements do not need to be rigidly connected to one another, each support arrangement can have a shorter length, thereby further improving the resonant frequency and reducing the probability of resonance in actual operation, while simultaneously reducing the torque acting on the support arrangements.

[0175] Based on this, the support frame for photovoltaic arrangements provided in the embodiments of the present disclosure exhibits good wind resistance, and the service life of several parts has been extended.

[0176] In contrast to the conventional requirements for precise butt joints and rigid connections between adjacent support arrangements and between the support arrangements and the upright elements, the support frame for photovoltaic arrangements provided in the embodiments of the present disclosure can be installed and connected more loosely and with less precision, and several parts can be self-balancing, thus saving manufacturing costs and allowing the arrangement to be assembled quickly and conveniently in a factory or on site.

[0177] The structure and other possible features of the support frame for photovoltaic arrays are explained in more detail below.

[0178] In some embodiments, the center of gravity of the photovoltaic module formed by the support block and the photovoltaic arrangement is not lower than a first connection point where the first connecting end of the connecting element is connected to the upright elements.

[0179] If the center of gravity (G) is higher than the first connection point, the support frame 100 for photovoltaic arrays exhibits the property of a self-tensioning structure, known as a tensegrity structure. The properties of a tensegrity structure include, at a minimum: it can absorb a certain amount of impact force when subjected to external disturbances and exhibits good self-balancing capabilities; furthermore, it can save material or reduce the strength requirements of components. In this case, the support frame 300 is movable in several degrees of freedom, or even six degrees of freedom, in practical applications.

[0180] Naturally, the first connection point is easy to drive or has good balance if the height of the first connection end is identical to the height of the center of gravity (G) of the photovoltaic module.

[0181] In Fig. 10 the center of gravity (G) of the photovoltaic module formed by the support arrangement 300 and the photovoltaic arrangements 4 is higher than the first connection end 201 of the connecting element which is connected to the upright elements 1, which means that the center of gravity (G) is higher than the first connection point.

[0182] In some embodiments, the center of gravity of the photovoltaic module is not higher than a second connection point where a second connection end 202 of the connecting element 200 is connected to the support arrangement 300.

[0183] If the center of gravity of the photovoltaic module is lower than the second connection point, the entire support frame 100 for the photovoltaic arrays exhibits a suspension characteristic, thus facilitating installation of the photovoltaic module at a lower height and also enabling maintenance at a lower height. The support frame 300 can also be movable in multiple degrees of freedom in practical applications. As shown in Fig. As shown in Figure 12, the second connection end 202 of the connecting element 200 is connected to the support arrangement 300, and the center of gravity (G) of the photovoltaic module is lower than the second connection end 202, which means that the center of gravity (G) is lower than the second connection point.

[0184] In some embodiments, the height of the center of gravity of the photovoltaic module lies between the height range of the connection ends at both ends of the connecting element. In other words, the height of the center of gravity lies between the height of the first connection point and the height range of the second connection point. At this point, the entire support structure 100 for photovoltaic arrays exhibits both suspension properties and a certain tensegrity property. In this case, the support structure 300 can also be movable in several degrees of freedom in practical applications. As in Fig. As shown in Figure 11, the height of the center of gravity (G) of the photovoltaic module is greater than the height of the second connection end 202 of the connecting element and less than the height of the first connection end 201 of the connecting element, which means that the height of the center of gravity (G) lies between the heights of the first connection point and the second connection point.

[0185] In some embodiments, the height of the upright elements 1 is adjustable. For example, the upright elements 1 have a telescopic configuration.

[0186] In some embodiments, the height of the connecting end of the upright elements 1 to the connecting element 200 is adjustable.

[0187] In some embodiments, the upright elements 1 can comprise a variety of differently positioned connecting ends that can be connected to the connecting element 200. For example, the upright elements 1 can, as in Fig. Figure 14 shows connecting ends 104 and 105, which are located at different positions on the upright elements 1.

[0188] By adjusting the height of the upright elements 1 or the height and position of the connecting ends 104 and 105 of the upright elements 1, the tilt angle of the support arrangement 300 can be changed to adapt to the change in the sun's altitude angle in different seasons.

[0189] Similarly, in some embodiments, the height of the connecting end of the support arrangement 300 to the connecting element 200 is adjustable. In other embodiments, the support arrangement 300 can comprise a plurality of differently positioned connecting ends that can engage with the connecting element 200. This allows the height of the center of gravity of the support arrangement 300 to be adjusted.

[0190] In some embodiments, the support arrangement includes a rotating shaft to provide a rotational support for the photovoltaic arrays, with tension elements exerting tensile forces on both sides of the rotating shaft to stabilize and adjust the support arrangement. Currently, the support frame 100 for photovoltaic arrays is a tracking support frame or a rotatable fixed support frame. The tracking support frame can have horizontal single-axis tracking or an inclined single-axis tracking structure, with the mount oriented in a north-south direction and the photovoltaic arrays being rotated by the mount unit to follow changes in the sun's angle.The rotatable fixed support can divide the entire year into several periods according to the geographical characteristics of the region and the solar radiation conditions, and the tilt angle of the support arrangement is adjusted according to the requirements for maximum generating capacity in each period.

[0191] Of course, in some possible cases, the tension elements can only exert tensile forces on one side of the axis of rotation.

[0192] If the support structure includes the rotating shaft, the center of gravity of the photovoltaic module cannot be lower than the axis of the rotating shaft, and the support structure for photovoltaic arrays exhibits the properties of a tensegrity structure. Of course, the center of gravity of the photovoltaic module can be lower than the axis of the rotating shaft, giving it a suspension property. Fig. show the height ratio between the center of gravity (G) of the photovoltaic module and the axis center of the rotating shaft 400.

[0193] In other embodiments, where the support arrangement does not include a rotating shaft, the support frame for photovoltaic arrays is a fixed, non-rotatable frame. For this fixed, non-rotatable frame, the optimal installation angle can be determined according to the geographical characteristics of the region where the fixed frame is located, the ratio of direct to scattered solar radiation throughout the year, and other factors, and the fixed installation can be carried out at the optimal installation angle.

[0194] In some embodiments, the support frame for photovoltaic arrangements may further include a drive mechanism for driving the tension element to move it, whereby the tension element pulls the rotating shaft to rotate or locks the rotating shaft in its position.

[0195] Depending on site conditions and other user requirements, the drive mechanism can utilize any suitable mechanism, including, for example, a rotary drive, a linear actuator, or an RV drive. These types of drive mechanisms are connected to and drive the tensioning element.

[0196] In some embodiments, the drive mechanism can be provided on the support 10 of the upright elements 1. The support 10 can be a fixed platform or another form of rigid structure. The support 10 can also be used to accommodate other components besides the drive mechanism. Fig. Figure 2 shows a case where the support 10 is a fixed platform. Fig. 2 the bracket 10 is provided on the upright elements 1, and components of the drive mechanism, such as the motor 9, are attached to the bracket 10.

[0197] In some embodiments, the drive mechanism is used to adjust the length of the pull element to drive the rotating shaft, or to wind or unwind the strip-shaped pull element to drive the rotating shaft. The strip-shaped pull element includes, among other things, the pull rope, pull chain, or pull belt. For example, the drive mechanism can set the rotating shaft 400 in motion by winding or unwinding the pull rope 6.

[0198] In some embodiments, such as in Fig. As shown in Figure 9A, the support arrangement can further comprise an arc-shaped bracket 5, and the arc-shaped bracket 5 is connected to the support beam 2, the support rod 3, the support plate, or the support frame. The arc-shaped bracket 5 has an approximately semicircular outline and is attached to the support arrangement, with two ends (or positions near the endpoints) of the arc-shaped bracket 5 each being provided with a fixed point of the pull rope 6. In this case, the pull element is the pull rope 6 connected to the arc-shaped bracket 5, and the drive mechanism comprises a rotating part and a motor 9. The rotating part is configured to retract the pull rope 6. The motor 9 is configured to drive the rotating part to rotate it, so that the arc-shaped bracket 5 is rotated by retracting and releasing the pull rope 6.The arc-shaped bracket 5 is advantageous for the precise calculation of the stroke of the pull cable 6, and the orientation angle of the photovoltaic modules 4 can be precisely adjusted by adjusting the motor 9 in combination with its size ratio. The motor 9 can drive one or more pull cables 6 and, via the pull cable 6, cause the arc-shaped bracket 5 to rotate. The arc-shaped bracket 5 drives the photovoltaic modules to rotate around the axis of rotation of the support arrangement 300. The wiring length and the angle of rotation remain in a fixed ratio to each other throughout operation, which simplifies the design of the entire drive mechanism. For illustration, see Figure 9. Fig. Figure 9A shows that the arc-shaped bracket 5 is connected to the support rods 3. The motor 9 can drive the rotating part to rotate it. The rotating part includes a drive wheel 7 and a drive gear 8. The rotating part can wind or unwind the pull rope 6, so that the pull rope 6 drives the arc-shaped bracket 5 to rotate.

[0199] In some optional embodiments, the arc-shaped bracket is provided with a guide groove for receiving the pull cable. The guide groove has a semi-spiral shape. The projection position of a first end of the guide groove on the axis of the rotating shaft is not the same as the projection position of a second end of the guide groove on the axis of the rotating shaft, with the axis of the rotating shaft serving as the reference. The semi-spiral structure allows for more precise control of the cable length, thereby improving the control accuracy of the drive mechanism with respect to the alignment angle of the photovoltaic modules.

[0200] In some alternative embodiments, the drive mechanism can further include a worm gear element for connecting the motor and the rotating part. In this case, the reverse self-locking function can be realized; that is, unless the motor is actively driven, the force transmitted by the wind to the photovoltaic modules cannot reverse the motor's rotation via the pull rope.

[0201] In some embodiments, the support frame for photovoltaic modules may further include a sensor device and a control device. The sensor device is configured to acquire environmental information. The control device is configured to control the drive mechanism to drive the rotating shaft or to lock the rotating shaft in its position according to the acquired environmental information. Environmental information includes, but is not limited to, lighting information, temperature information, humidity information, wind information, and other climate information. By using the sensor device and the control device, the support frame for photovoltaic arrays can be intelligently controlled and driven.In some alternative embodiments, for example, if it is necessary to track solar irradiance each day, the control unit can control the drive mechanism so that the photovoltaic arrays are indirectly rotated by 120 degrees based on the illumination information detected by the sensor unit. If the environmental information detected by the sensor unit indicates that it is currently snowing, the control unit can control the drive mechanism so that the photovoltaic module tilts towards the ground, forming an enclosed angle of approximately 75 degrees. If the environmental information detected by the sensor unit indicates that it is currently windy, the control unit can control the drive mechanism so that the photovoltaic module moves approximately parallel to the ground or the wind direction.

[0202] In some embodiments, such as in Fig. As shown in Figure 7A, the connecting element comprises a double-bore bushing 11. The two ends of the support arrangement 300 are each provided with a coupling shaft 301 of the support arrangement. The upright element 1 is provided with a coupling shaft 101 of the upright element. The double-bore bushing 11 comprises a first through-bore 111 for receiving the coupling shaft of the support arrangement and a second through-bore 112 for receiving the coupling shaft 101 of the upright element. The remainder of the upright elements 1, with the exception of the coupling shafts 101 of the upright element, can be considered the main body of the upright elements 1. The remainder of the support arrangement 300, with the exception of the coupling shaft 301 of the support arrangement, can be considered the main body of the support arrangement 300.

[0203] In some alternative embodiments, the opening of the first through-hole 111 is larger than the opening of the second through-hole 112.

[0204] In some alternative embodiments, the distance between the axial center of the first through-hole 111 and the axial center of the second through-hole 112 can be determined according to the center of gravity of the photovoltaic module, so that the center of gravity is not higher or lower than the axial center of the rotating shaft 400 for the rotation of the support arrangement.

[0205] In some optional embodiments, parameters such as the difference between the opening of the first through-hole 111 and the outer diameter of the coupling shaft 301 of the support arrangement, the difference between the opening of the second through-hole 112 and the outer diameter of the coupling shaft 101 of the upright element, the difference between the length of the first through-hole 111 and the length of the coupling shaft 301 of the support arrangement, the difference between the length of the second through-hole 112 and the length of the coupling shaft 101 of the upright element, or the like, can be determined according to the actual requirements, so that the adaptation of the coupling shaft 301 of the support arrangement and the first through-hole 111,the adaptation of the coupling shaft 101 of the upright element to the second through-hole 112 or the strength of the entire support frame for photovoltaic arrangements and the load-bearing capacity of the components can be rationalized.

[0206] In some alternative embodiments, the coupling shaft 301 of the support arrangement and / or the coupling shaft 101 of the upright element are provided with an injection channel for a lubricant, such as lubricating oil, which may have a passage at the corner end. The lubricating oil can be injected with a high-pressure oil gun to fulfill the functions of lubrication and dust prevention.

[0207] In some alternative embodiments, the support arrangement is provided with a mounting bore for attaching the coupling shaft of the support arrangement. The upright element 1 is provided with a mounting bore for attaching the coupling shaft 101 of the upright element.

[0208] In some alternative embodiments, the coupling shaft 301 of the support arrangement is detachable from the main body of the support arrangement 300. The coupling shaft 101 of the upright element is detachable from the main body of the upright element 1.

[0209] In some alternative embodiments, the connecting element may further comprise a metal sleeve provided between the first through-hole 111 and the connecting shaft of the support assembly. The metal sleeve may be made of copper. The thickness of the metal sleeve can be adjusted according to the actual requirements. The metal sleeve can enclose the lubricant and contributes to reducing abrasion and preventing dust formation. Since the rotational force required is relatively low, the coupling shaft 101 of the upright element may not require a metal sleeve. Furthermore, the connecting element may include a cover made of a composite material consisting of two or more materials, such as a metal, a ceramic, or a polymer.

[0210] In some alternative embodiments, the connecting element may further comprise a limiting element to limit a relative sliding path of the coupling shaft 301 of the support arrangement in the first through-bore 111 and also to limit a relative sliding path of the coupling shaft 101 of the upright element in the second through-bore 112.

[0211] In some alternative embodiments, the limiting element may include a threaded screw piece. In this case, the coupling shaft of the support arrangement is provided with a thread that meshes with the screw piece, and the coupling shaft 101 of the upright element is provided with a thread that meshes with the screw piece.

[0212] In some alternative embodiments, the coupling shaft 301 of the support arrangement and the coupling shaft 101 of the upright element can be screws, and the screw piece can be a nut.

[0213] In some alternative embodiments, the limiting element may further comprise a pin and a washer that mesh with the screw. After the screws have been inserted through the mounting holes of the upright elements 1 and the second through-holes 112, the nuts are tightened and the bolts inserted. The screw can be passed through the mounting hole and the first through-hole 111 provided on the support assembly, with the metal cover pre-inserted into the first through-hole 111 and having a precisely matched structure. The washer is in contact with the upright elements 1.

[0214] In some embodiments, the support frame for the photovoltaic arrays may further include a lifting element for adjusting the height of the support frame and / or the photovoltaic arrays during installation. The lifting element includes, but is not limited to, a winch, a lifting mechanism with a pulley, or another type of lifting mechanism. For example, the lifting element may include a pulley and a sling. One or more pulleys are suspended from the upright elements, and the support frame or the photovoltaic arrays can be raised to the height required for a particular installation connection by adjusting the sling and pulleys.

[0215] The lifting element can be attached to the upright elements or to an object other than the upright elements. It is intended that the lifting element can be attached to the ground, for example, if it is designed as a winch.

[0216] In some embodiments, the support frame for photovoltaic arrays can be applied to an array of photovoltaic power generation systems in which there are multiple support arrays and one or more support arrays are located between adjacent support elements. For example, there may be ten support arrays in a row, and each support array has upright elements on both sides of its outer surface, resulting in a total of eleven upright elements.

[0217] In some embodiments, the support arrangement comprises a rotating shaft and a bearing element connected to the rotating shaft for supporting the photovoltaic arrays. The bearing elements of at least two adjacent support arrangements are connected to each other by an interface element. The interface element may comprise a chain, a rope, or a rod. The bearing element may be provided with interface sections, each located on both sides of the axial center of the rotating shaft, to establish a connection with at least two interface elements. The bearing elements of at least two adjacent support arrangements may be movably connected to each other by the interface element.

[0218] The bearing element can be a support beam, a support rod, a support plate, or a support frame connected to the rotating shaft. As in Fig. As shown in Figure 3, in the case of two adjacent support arrangements, one support arrangement has connection points 1003 and 1005 (which are normally provided on the support arrangement of the support arrangement), and another support arrangement may have connection points 1004 and 1006 (which are normally provided on the support arrangement of the support arrangement). These connection ends are connected to each other by interface elements. That is, interface elements connect the connection points 1003 and 1004 ( Fig. 3) and connect connection points 1005 and 1006.

[0219] Fig. Figure 17 illustrates a case in which several support arrangements are interconnected in some embodiments. Fig. Figure 17 comprises a first support arrangement comprising a bearing element 501 and a rotary shaft 401. A second support arrangement comprises a bearing element 502 and a rotary shaft 402. The bearing element 501 is connected to the bearing element 502 via an interface element 1000. Fig. 17 The support frame for photovoltaic arrangements can further comprise a reinforcing element 1001 that connects the upright element 1 and a base body 1002 to increase the overall strength and stability of the support frame. Alternatively, the reinforcing element 1001 can be a rope or a rod.

[0220] In some alternative embodiments, the drive mechanism can drive the traction element to move it, so that the traction element simultaneously drives two or more support arrangements to rotate or simultaneously locks two or more support arrangements in their position.

[0221] In some alternative embodiments, of the several upright elements corresponding to the simultaneously driven support assemblies, the upright element in the middle position is used to attach the drive mechanism. For example, ten support assemblies are driven simultaneously, and the drive mechanism is attached to the most central upright element of the eleven upright elements.

[0222] In some alternative embodiments, the drive mechanism is used to drive a group of tension elements, and the group of tension elements may be connected to one or more support arrangements.

[0223] Fig. Figure 18 illustrates the case in which, according to some embodiments, a drive mechanism simultaneously drives two support arrangements. In particular, the drive mechanism 900 simultaneously drives the two support arrangements 300, which are located on the left and right sides of the upright elements 1, respectively, and the two support arrangements 300 are connected by the interface element 1000. The interface element 1000 is not limited to a rigid connecting element and can be a flexible connecting element.

[0224] The support structure for photovoltaic arrays provided by the embodiments of the first aspect of the present disclosure can be applied to a large-scale photovoltaic power generation system. Since the adjacent support arrangements do not need to be rigidly connected to one another, each support arrangement can be of a shorter length, thereby further improving the resonant frequency and reducing the likelihood of resonance in actual applications, while simultaneously reducing the torque acting on the support arrangements.

[0225] In summary, the support structure for photovoltaic arrangements provided in the embodiments of the disclosure has a simple overall structure, good self-balancing properties, is suitable for large-scale production and installation, significantly saves material and labor costs, and ultimately reduces electricity generation costs.

[0226] In a second aspect, some embodiments of the present disclosure offer a method for installing a support frame for photovoltaic arrangements, which is suitable for installing the support frame for photovoltaic arrangements provided by the embodiments of the present disclosure in the first aspect.

[0227] When installing conventional tracking support racks or fixed racks, the entire installation process can usually only be carried out on one side due to the complexity of the rack components. At this point, all components of the rack must be transported to the installation site.

[0228] However, according to the first aspect, compared to the conventional requirements for a precise butt joint and a rigid connection between adjacent support arrangements as well as between the support arrangements and the upright elements, the support frame for photovoltaic arrangements provided by the embodiments of the present disclosure can be installed and connected more loosely and with less precision, and a large number of parts can be self-balancing, thus saving manufacturing costs and allowing the arrangement to be assembled quickly and conveniently in a factory or on site.

[0229] The support frame for photovoltaic arrays provided in the embodiments of the disclosure can, in some cases, be used to pre-assemble parts of the support frame into an assembly module before it is transported to a site. Therefore, the assembly module only needs to be installed on-site, significantly reducing the on-site installation effort. Assembly can take place either at the factory where the parts are manufactured or at other locations after manufacturing and before shipment to the site.

[0230] The procedure for installing the support frame for photovoltaic arrays, which is provided in the second aspect, may include the following steps:

[0231] Assembling the photovoltaic arrays and the support structure to form an array module; and movable connection of the arrangement module to the support elements.

[0232] In some cases, the photovoltaic arrays can be pre-assembled with the support structures to form an array module before transport to the site. Therefore, the array module and the support elements only need to be movably connected on-site, saving considerable time during installation. Of course, on-site assembly is also practical and feasible.

[0233] The connecting element can be attached to the support elements on site, but can also be pre-assembled as part of the assembly module. Furthermore, other components intended for the struts, such as purlins, braces, strut connectors, strut stiffeners, or the like, can also be pre-assembled.

[0234] In some embodiments, the connecting element comprises a first connecting component element and a second connecting component that can be movably connected to one another. At this stage, the first connecting component and the support arrangement can be pre-connected or pre-connected, and the second connecting component and the upright elements can be connected; and the first connecting element is connected to the second connecting element to achieve the movable connection of the arrangement module and the upright elements.

[0235] In some embodiments, the first connecting component is a loop element or a hook element, and the second connecting component is a loop element or a hook element. Based on the [reference to the following] Fig. 2 and Fig. In the configuration shown in Figure 5, it is now possible to connect the loop element 12 to the support arrangement in advance or on site, the hook element 13 to the support elements 1 and the loop element 12 to the hook element 13 in order to create a movable connection between the arrangement module and the support elements 1.

[0236] In some embodiments, for example in the Fig. 2 and Fig. In the configuration shown in Figure 7, the connecting means comprise double-bore bushings 11 to movably connect the arrangement module to the upright elements 1. In particular, the coupling shaft 301 of the support arrangement is guided through the first through-bore 111 and subjected to a position-limiting fixation, and the coupling shaft 101 of the upright element is guided through the second through-bore 112 and subjected to a position-limiting fixation.

[0237] In some alternative embodiments, when the coupling shaft 301 of the support assembly is inserted through the first through-hole 111 and fixed by a stopper, a metal sleeve is inserted into the first through-hole 111 and the coupling shaft 301 of the support assembly is inserted through the metal sleeve.

[0238] In some alternative embodiments, the coupling shaft 301, which may also be referred to as the connecting shaft, of the support arrangement and the coupling shaft 101 of the upright element are bolts, and the following fastening is carried out: a metal sleeve is inserted into the first through-hole 111, so that the coupling shaft 301 of the support arrangement is passed through the metal sleeve; the nut is screwed onto the bolt, and the stud is placed on the bolt.

[0239] In some embodiments, which are characterized by the in Fig. As illustrated in Figure 19, the support element 1 includes a fastening section 2000 to raise and hold the support assembly at a desired mounting height. Once the photovoltaic array and the support assembly are mounted, the support assembly is suspended or supported by the fastening section 2000, and the photovoltaic arrays and the support assembly are mounted at the desired mounting height.

[0240] In some embodiments, which are characterized by the in Fig. As illustrated in Figure 13, the lifting element included in the support frame for photovoltaic arrays can be a 2900 winch. The 2900 winch can be attached to the upright elements to adjust the height of the support frame and / or the photovoltaic arrays in the assembled state. Furthermore, the lifting element included in the support frame for photovoltaic arrays can be, as shown in Figure 13, a 2900 winch. Fig. The configuration shown in diagram 20 uses a Winch 3000. The Winch 3000 can adjust the height of the support structure and / or the photovoltaic arrays during assembly and / or when making the movable connection.

[0241] In a third aspect, the present disclosure provides a method for setting a support frame for photovoltaic arrangements, which is suitable for an application in which the photovoltaic module support provided by the first aspect of the present disclosure is used as a support frame for tracking (i.e., as a tracker), wherein the support arrangement includes a rotating shaft to provide a rotating mount for the photovoltaic arrangements.

[0242] During the adjustment process of the conventional tracking support frame for photovoltaic arrays, the length of the support is very large due to the rigid connection of several main supports, so that the interconnected main supports must be rotated as one long single shaft.

[0243] However, according to the support frame for photovoltaic arrangements provided by the embodiments of the first aspect of the present disclosure, it is not necessary to rotate a long single shaft as in the conventional tracking support frame, but a relatively short support arrangement can be adjusted independently according to the environmental information, so that a more precise adjustment is achieved and the power generation efficiency is improved.

[0244] The method for adjusting the support frame for photovoltaic arrangements according to some embodiments of the present disclosure may include the following step:

[0245] Controlling the drive mechanism to move the traction element according to sunlight information, temperature information and / or climate information, so that the rotating shaft of the support arrangement is driven to rotate, and the photovoltaic arrangement has a preset tilt angle.

[0246] In some embodiments, the drive mechanism in the relevant area can be controlled such that the tilt angle of the photovoltaic arrays in that area is adjusted independently according to sunlight, temperature, and / or climate information from different areas, thus enabling local precision control. For example, if a cloud passes over the support frame, it may not cover a large area; however, the conventional tracking support frame adjusts the rotation of the entire long single shaft, altering the orientation angles of some photovoltaic arrays not covered by the cloud and negatively impacting power generation efficiency.The adjustment method provided by some embodiments of the disclosure can rotate the support arrangements of only one or more of the several shorter support frames, thus preventing all support arrangements from rotating together and achieving a more precise adjustment.

[0247] Apart from the captured environmental information, the drive mechanism can be controlled to move the traction element according to a control instruction entered by the user, so that the rotating shaft of the support arrangement is set in motion and the photovoltaic arrangements have a preset tilt angle.

[0248] The support structure is adjusted according to the change in the angle of incidence of sunlight, the orientation of the photovoltaic arrangements is adjusted according to the lighting conditions, the enclosed angle between the photovoltaic arrangements and the direct sunlight can be reduced, the amount of radiation of sunlight incident on the photovoltaic arrangements is increased and thus the power generation efficiency is effectively improved.

[0249] In some embodiments, the control of the drive mechanism in the adjustment procedure can be implemented by a controller or processor that issues the corresponding control commands.

[0250] In a fourth aspect, some embodiments of the present disclosure offer a photovoltaic power generation system.

[0251] A photovoltaic power generation system is a power generation system that directly converts solar radiation energy into electrical energy using the photovoltaic effect of a photovoltaic cell. Photovoltaic power generation systems have a wide range of applications, such as solar power plants, rooftops, buildings, agriculture, fishing, public facilities, landscaping, and similar uses.

[0252] A photovoltaic power generation system generally comprises photovoltaic arrays, an electrical energy storage array, an electrical power transmission array (including, but not limited to, a charge and discharge controller, an inverter, a power distribution cabinet, a cable line, etc.), or similar components. In some cases, the photovoltaic power generation system may further include a tracking control module, which may include components such as a communication control box, a sensor, a cloud platform, a switch cabinet, or similar equipment.The tracking control module can fully take into account factors and requirements such as shielding between photovoltaic modules, cloudy weather, self-cleaning on rainy days, protection from strong winds or the like, according to an astronomical algorithm or an artificial intelligence algorithm, calculate the angle of incidence of local sunlight in real time according to the longitude and latitude as well as the local time of the site and adjust the photovoltaic modules to a suitable orientation angle.

[0253] The photovoltaic power generation system provided in some embodiments of the present disclosure may comprise the support frame for photovoltaic arrays provided in the embodiments of the first aspect and at least one photovoltaic array. Furthermore, the photovoltaic array may also comprise other arrangements that are common in photovoltaic power generation systems, such as electrical power supply arrangements and electrical energy storage arrangements.

[0254] The photovoltaic power generation system provided by the embodiment of the disclosure exhibits excellent wind resistance, is suitable for large-scale manufacturing and installation, significantly saves material and labor costs, ultimately reduces power generation costs and improves the power generation efficiency of the photovoltaic power generation system.
