Description

Technical Field

[0001] This application relates to the field of solar energy technology, and in particular to a photovoltaic system array with a synchronous detection system unit and a synchronous detection system. Background Technology

[0002] In existing technologies, photovoltaic (PV) system arrays consist of multiple PV system units. Any PV system unit may include PV panel modules and adjustable support modules. PV panel modules are primarily used to convert solar energy or light energy into electrical energy. Adjustable support modules support the PV panel modules and are mainly used to adjust their orientation. It is understood that the sun rises in the east and sets in the west relative to the Earth periodically. To improve the efficiency of solar energy reception, the orientation of the PV panel modules can be adjusted periodically. The adjustment period for one type of PV panel module may be on a daily basis, while for another type it may be on a yearly basis.

[0003] In the process of developing the existing technology, the inventors discovered that:

[0004] If the angle of the photovoltaic panel component in any photovoltaic system unit in the photovoltaic system array does not conform to the preset angle, it will affect the maximization of the photovoltaic conversion capacity of the entire photovoltaic system array.

[0005] However, the deployment of photovoltaic system units in a photovoltaic system array is relatively dense, making it difficult to detect photovoltaic system units whose angles are adjusted to be different from the preset angles.

[0006] Therefore, there is a need to provide a photovoltaic system array with a synchronous detection system unit and a synchronous detection system to solve the technical problem that the orientation angle deviation between photovoltaic system units is difficult to detect, resulting in a reduction in the overall power generation capacity of the photovoltaic system array. Summary of the Invention

[0083] By implementing a synchronous detection system unit comprising guiding components, flexible suspension cables, and a triggering mechanism, orientation angle deviations between photovoltaic (PV) system units within a PV system array can be detected at a lower cost. When an orientation angle deviation exists between PV system units in the array, the triggering mechanism sends a notification, alerting relevant personnel to perform adjustments and maintenance, ensuring timely maintenance and maximizing the overall power generation capacity of the PV system array. Furthermore, the synchronous detection system unit primarily relies on physical signals, resulting in a lower failure rate compared to electronic detection systems based on digital signals. In large-scale PV system array deployments, the maintenance cost of this synchronous detection system unit is significantly lower. Attached Figure Description

[0098] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0099] Please refer to Figures 1 to 2 This application provides a photovoltaic system array 100 with a synchronous detection system unit. The photovoltaic system array 100 is composed of multiple photovoltaic system units and is mainly installed in areas with abundant solar energy resources. Typically, the multiple photovoltaic system units are distributed in an array, and each photovoltaic system unit can be regarded as an independent photoelectric conversion functional unit.

[0100] Each photovoltaic system unit includes at least:

[0101] Photovoltaic panel modules are used to convert light energy into electrical energy;

[0102] An adjustable support assembly is provided for supporting the photovoltaic panel assembly and for adjusting the orientation of the photovoltaic panel assembly to receive light energy at an appropriate angle.

[0103] The photovoltaic (PV) panel assembly is used to convert light energy into electrical energy. The PV panel assembly can be primarily made of polycrystalline silicon or monocrystalline silicon, or other semiconductor materials with photoelectric effects. Sunlight shines on the PV panel assembly and is absorbed at its interface layer. The PV panel assembly, made of semiconductor materials, has a PN junction. Photons of sufficient energy in the absorbed sunlight can excite electrons in the PN junction from their covalent bonds, resulting in electron-hole pairs. Before recombination, the electrons and holes near the interface layer are separated by the electric field of the space charge. This charge separation at the interface layer generates a measurable outward voltage across the PN junction. The more electron-hole pairs generated at the interface layer of the PV panel assembly, the greater the current. The more light energy absorbed by the interface layer of the PV panel assembly, and the larger the area of ​​the interface layer (i.e., the irradiated area of ​​the PV panel assembly), the greater the current generated by the PV panel assembly. The current generated by the PV panel assembly can be collected through a busbar and used as a power source.

[0104] The adjustable support assembly supports the photovoltaic panel assembly and can adjust the orientation of the photovoltaic panel assembly to receive light energy at an appropriate angle. Specifically, the adjustable support assembly includes a support frame, a bracket that can pivot relative to the support frame, and an adjustment mechanism disposed between the bracket and the support frame. In a specific application scenario, the photovoltaic panel assembly is mounted on the bracket, and the weight of the photovoltaic panel assembly is supported vertically by the support frame. The bracket as a whole can pivot relative to the support frame, forming shapes with different angles to the ground. In one embodiment provided in this application, the adjustment mechanism can adopt a jack structure. Thus, the adjustment mechanism can essentially be regarded as a four-bar linkage structure, or represented as a rhombus structure in the side view projection. One of the two vertices of the rhombus is connected to the bracket, and the other of the two vertices is disposed on the support frame. The projection of the two vertices of the rhombus adjustment mechanism, the pivot point of the support or bracket, and the pivot axis in the side view forms the three vertices of a triangle. The projection of the jack, bracket, and support frame in the side view forms the three sides of the triangle. Since the support frame is fixed to the ground, the angle between the bracket and the support frame can be changed by adjusting the angle of the rhombus of the adjustment mechanism, thereby changing the angle between the bracket and the ground.

[0105] In the specific embodiment provided in this application, the adjustment mechanism is implemented using a jack structure. The projected length of the mechanism on the side is adjusted by changing the distance between the vertices of the rhombus perpendicular to the support direction of the photovoltaic panel assembly. Specifically, an adjustment rod is provided between the two vertices of the jack structure. Rotation of the adjustment rod changes the distance between the two vertices of the rhombus adjustment mechanism, ultimately changing the angle between the bracket and the ground. In this specific embodiment, the rotation of the adjustment rod can be achieved by a motor-driven assembly.

[0106] Meanwhile, to ensure the power generation capacity of the photovoltaic system unit, the photovoltaic panel components within the unit must be able to receive vertically incident sunlight. The angle at which the photovoltaic panel components receive vertically incident sunlight is referred to as the preset angle. The preset angle can be obtained through an astronomical algorithm, based on the geographical location of the photovoltaic system unit's longitude and latitude, combined with the changing pattern of the sun's altitude over time. The astronomical algorithm can be viewed as a database or algorithmic model of the sun's altitude, or the angle of sunlight, as a function of longitude, latitude, and time.

[0107] In practical implementation, the photovoltaic system unit can be equipped with a control component electrically connected to the photovoltaic panel assembly and the motor drive assembly. This control component controls the motor drive assembly to adjust the adjustable support assembly according to a preset movement pattern until the photovoltaic panel assembly reaches a preset angle, thereby receiving vertically irradiated light energy. The control component can be implemented using a microcontroller or a microprocessor with simple functions.

[0108] Of course, the above is the implementation scheme for any photovoltaic system unit in the photovoltaic system array 100. Multiple photovoltaic system units are distributed in an array to form the photovoltaic system array 100.

[0109] In such a scenario, to ensure the overall power generation capacity of the photovoltaic system array 100, each photovoltaic system unit in the photovoltaic system array 100 is required to receive vertically irradiated light energy.

[0110] However, in practical applications, the inventors found that it was difficult to detect photovoltaic system units in the photovoltaic system array 100 whose angles did not conform to the preset angles. If they could not be adjusted in time, it would be difficult to maximize the overall power generation capacity of the photovoltaic system array 100 in the long run.

[0111] Please refer to Figures 3 to 4 To address the technical problem that the orientation angle deviation between photovoltaic system units is difficult to detect, resulting in a reduction in the overall power generation capacity of the photovoltaic system array 100, the photovoltaic system array 100 described in this application is provided with a synchronous detection system unit 13. The synchronous detection system unit 13 is connected to multiple photovoltaic system units in the photovoltaic system array 100 and is used to detect the orientation angle deviation between photovoltaic system units in the photovoltaic system array 100.

[0112] The following describes the implementation scheme of a photovoltaic system array 100 having a synchronous detection system unit 13, taking the photovoltaic system array 100 including at least two photovoltaic system units as an example.

[0113] The photovoltaic system array 100 includes at least:

[0114] First photovoltaic system unit 11;

[0115] Second photovoltaic system unit 12;

[0116] At least a synchronous detection system unit 13 connected to the first photovoltaic system unit 11 and the second photovoltaic system unit 12 is used to detect the orientation angle deviation between the first photovoltaic system unit 11 and the second photovoltaic system unit 12;

[0117] The synchronous detection system unit 13 includes:

[0118] Guide components 131 are respectively installed in the first photovoltaic system unit 11 and the second photovoltaic system unit 12;

[0119] The flexible suspension cable 132 connected to the guide component 131 is used to reflect the orientation angle deviation of the first photovoltaic system unit 11 and the second photovoltaic system unit 12.

[0120] The triggering mechanism 133 connected to the flexible suspension cable 132 is used to set the orientation angle deviation threshold.

[0121] When the orientation angle deviation between the first photovoltaic system unit 11 and the second photovoltaic system unit 12 exceeds the orientation angle deviation threshold, the triggering mechanism 133 is also used to send a prompt message.

[0122] It is understood that the flexible suspension cable 132 at least has a flexible suspension cable 132 body. Typically, the flexible suspension cable 132 is connected to the guide assembly 131 and the triggering mechanism 133, thus the flexible suspension cable 132 has a connecting portion and a flexible suspension cable 132 body. In specific application scenarios, the flexible suspension cable 132 body is typically a metal wire rope.

[0123] In another specific embodiment provided in this application, the flexible suspension cable 132 has at least a flexible suspension cable 132 body and an anchor disposed at one end of the flexible suspension cable 132 body. The anchor is used to establish an anchoring relationship between the flexible suspension cable 132 body and the guide component 131.

[0124] The guide components 131 are respectively disposed on the first photovoltaic system unit 11 and the second photovoltaic system unit 12, and allow the flexible suspension cable 132 to pass through, so that the flexible suspension cable 132 reflects the orientation angle deviation of the first photovoltaic system unit 11 and the second photovoltaic system unit 12.

[0125] The working principle of the flexible suspension cable 132 in reflecting the orientation angle deviation of the first photovoltaic system unit 11 and the second photovoltaic system unit 12 is described below:

[0126] Guide components 131 are respectively disposed in the first photovoltaic system unit 11 and the second photovoltaic system unit 12, and the main body of the flexible suspension cable 132 passes through the guide components 131. When the photovoltaic panel components of the first photovoltaic system unit 11 and the photovoltaic panel components of the second photovoltaic system unit 12 have the same orientation angle, the photovoltaic panel components of the first photovoltaic system unit 11 and the photovoltaic panel components of the second photovoltaic system unit 12 are parallel to each other. When the photovoltaic panel components have the same orientation angle, the distribution interval of the guide components 131 is the shortest, and the main body of the flexible suspension cable 132 is subjected to tension from both ends of the flexible suspension cable 132. However, when there is a deviation in the orientation angle of the photovoltaic panel components, the distribution interval of the guide components 131 becomes longer, and there is a height difference, which causes the main body of the flexible suspension cable 132 passing through the guide components 131 to be subjected to shear force. Since the main body of the flexible suspension cable 132 has a fixed length, when the main body of the flexible suspension cable 132 is subjected to shear force, the main body of the flexible suspension cable 132 is displaced relative to the guide components 131, thereby converting the shear force into tension force and transmitting the tension force to the triggering mechanism 133 connected to the flexible suspension cable 132. As can be seen, the main body of the flexible suspension cable 132 can convert the orientation angle deviation of the first photovoltaic system unit 11 and the second photovoltaic system unit 12 into tension and transmit it to the triggering mechanism 133. This tension transmission is precisely how the flexible suspension cable 132 reflects the orientation angle deviation of the first photovoltaic system unit 11 and the second photovoltaic system unit 12.

[0127] The guide component 131 supports the passage of the flexible suspension cable 132. In the application scenarios provided in this application, the guide component 131 can have various forms.

[0128] Furthermore, in one specific embodiment provided in this application, the guide component 131 provides an abutment portion that allows the flexible suspension cable 132 to pass through. The guide component 131 includes at least a first fixed pulley disposed on the photovoltaic panel assembly corresponding to the first photovoltaic system unit 11 and a second fixed pulley disposed on the photovoltaic panel assembly corresponding to the second photovoltaic system unit 12.

[0129] The position of the pulley contact portion of the first fixed pulley is projected to the position of the pulley contact portion of the second fixed pulley;

[0130] One end of the flexible suspension cable 132 is fixed to the first fixed pulley;

[0131] The main body of the flexible suspension cable 132 passes sequentially through the pulley contact part of the first fixed pulley and the pulley contact part of the second fixed pulley;

[0132] The other end of the flexible suspension cable 132 is fixed to the triggering mechanism 133.

[0133] It is understood that, in this specific embodiment, the guide component 131 includes a plurality of fixed pulleys, each of which provides a pulley contact portion to support the passage of the main body of the flexible suspension cable 132. Each photovoltaic panel of any photovoltaic system unit in the photovoltaic system array 100 is provided with at least one fixed pulley. One end of the flexible suspension cable 132 is fixed to the fixed pulley of the photovoltaic system unit corresponding to the beginning of the photovoltaic system array 100. Specifically, the flexible suspension cable 132 can be attached to the fixed pulley of the photovoltaic system unit at the beginning of the array, forming the connecting portion of the flexible suspension cable 132.

[0134] Taking the photovoltaic system array 100 as an example, which includes at least a first photovoltaic system unit 11 and a second photovoltaic system unit 12, the photovoltaic panel of the first photovoltaic system unit 11 is equipped with a first fixed pulley, and the photovoltaic panel of the second photovoltaic system unit 12 is equipped with a second fixed pulley. The position of the pulley contact portion of the first fixed pulley and the position of the pulley contact portion of the second fixed pulley are projected onto each other. In other words, the first fixed pulley and the second fixed pulley have the same shape, and the installation position of the first fixed pulley on the photovoltaic panel assembly of the first photovoltaic system unit 11 is the same as the installation position of the second fixed pulley on the photovoltaic panel assembly of the second photovoltaic system unit 12. The first photovoltaic system unit 11 can serve as the starting photovoltaic system unit of the photovoltaic system array 100. Thus, one end of the flexible suspension cable 132 is fixed to the first fixed pulley corresponding to the first photovoltaic system unit 11.

[0135] Furthermore, in another specific embodiment provided in this application, the guide component 131 provides a through hole allowing the flexible suspension cable 132 to pass through. The guide component 131 includes at least a first lug disposed on the photovoltaic panel assembly corresponding to the first photovoltaic system unit 11 and a second lug disposed on the photovoltaic panel assembly corresponding to the second photovoltaic system unit 12;

[0136] The position of the through hole of the first lifting lug is projected to the position of the through hole of the second lifting lug;

[0137] One end of the flexible suspension cable 132 is fixed to the first lifting lug;

[0138] The main body of the flexible suspension cable 132 passes through the through hole of the first lug and the through hole of the second lug in sequence;

[0139] The other end of the flexible suspension cable 132 is fixed to the triggering mechanism 133.

[0140] It is understood that, in this specific embodiment, the guide component 131 includes a plurality of lugs, each lug having a through hole to support the passage of the main body of the flexible suspension cable 132. Each photovoltaic panel of any photovoltaic system unit in the photovoltaic system array 100 is provided with at least one lug. One end of the flexible suspension cable 132 is fixed to the lug of the photovoltaic system unit at the beginning of the corresponding photovoltaic system array 100. Specifically, the flexible suspension cable 132 can be tied to the lug of the photovoltaic system unit at the beginning of the corresponding array, forming the connecting part of the flexible suspension cable 132. Alternatively, the anchor of the flexible suspension cable 132 can establish an anchoring relationship with the lug of the photovoltaic system unit at the beginning of the corresponding array.

[0141] Taking the photovoltaic system array 100 as an example, which includes at least a first photovoltaic system unit 11 and a second photovoltaic system unit 12, the photovoltaic panel of the first photovoltaic system unit 11 is provided with a first lifting lug, and the photovoltaic panel of the second photovoltaic system unit 12 is provided with a second lifting lug. The through-hole position of the first lifting lug and the through-hole position of the second lifting lug are in a projection relationship. In other words, the first lifting lug and the second lifting lug have the same shape, and the installation position of the first lifting lug on the photovoltaic panel assembly of the first photovoltaic system unit 11 is the same as the installation position of the second lifting lug on the photovoltaic panel assembly of the second photovoltaic system unit 12. The first photovoltaic system unit 11 can serve as the starting photovoltaic system unit of the photovoltaic system array 100. In this way, one end of the flexible suspension cable 132 is fixed to the first lifting lug corresponding to the first photovoltaic system unit 11.

[0142] Furthermore, the photovoltaic system array 100 has a longitudinal array direction;

[0143] The first photovoltaic system unit 11 serves as the starting point, the second photovoltaic system unit 12 serves as the ending point, and the line connecting the first photovoltaic system unit 11 and the second photovoltaic system unit 12 defines the longitudinal array direction.

[0144] The flexible suspension cable 132 has an extension direction parallel to the longitudinal array direction.

[0145] It is understood that the guide component 131 defines the extension direction of the flexible suspension cable 132. In a scenario where a single fixed pulley or a single lug is provided on the photovoltaic panel of any photovoltaic system unit, the arrangement direction of the guide component 131 is naturally parallel to the extension direction of the photovoltaic system unit. However, in a scenario where multiple fixed pulleys or multiple lugs are provided on the photovoltaic panel of any photovoltaic system unit, this application preferably arranges the multiple fixed pulleys or multiple lugs in a longitudinal array. The multiple fixed pulleys or multiple lugs have a longitudinal array direction, and this longitudinal array direction is parallel to the longitudinal array direction of the photovoltaic system array 100. This minimizes the length of the flexible suspension cable 132 passing through the guide component 131, and ensures that the extension direction of the flexible suspension cable 132 is parallel to the longitudinal array direction.

[0146] The other end of the flexible suspension cable 132 is connected to a triggering mechanism 133, which is used to set an orientation angle deviation threshold. The triggering mechanism 133 can be set independently (i.e., not connected to the photovoltaic system unit) or attached to the photovoltaic system unit. Of course, in a specific embodiment where the triggering mechanism 133 is attached to the photovoltaic system unit at the end of the corresponding array, the triggering mechanism 133 is attached to the photovoltaic system unit at the end of the array. Taking the photovoltaic system array 100 as an example, which includes at least a first photovoltaic system unit 11 and a second photovoltaic system unit 12, with the first photovoltaic system unit 11 serving as the starting photovoltaic system unit of the photovoltaic system array 100, and the second photovoltaic system unit 12 serving as the ending photovoltaic system unit of the photovoltaic system array 100. In this case, the triggering mechanism 133 can be set on the photovoltaic panel assembly of the second photovoltaic system unit 12, or on the adjustable support assembly of the second photovoltaic system unit 12.

[0147] Please refer to Figures 5 to 6 The triggering mechanism 133 includes at least:

[0148] A movable rod 1331 connected to the flexible suspension cable 132 and guided by the flexible suspension cable 132 to make axial displacement;

[0149] The elastic element 1332 sleeved on the moving rod 1331 is used to guide the moving rod 1331 to reset;

[0150] A travel switch 1333, positioned in the compression direction of the elastic element 1332, is used to define an orientation angle deviation threshold.

[0151] It is understood that the movable rod 1331 includes at least a main body of the movable rod 1331 and a through hole disposed at one end of the main body of the movable rod 1331. The through hole is connected to the flexible suspension cable 132. When there is a deviation in the orientation angle of the photovoltaic panel assembly, and the main body of the flexible suspension cable 132 is subjected to shear force, the main body of the flexible suspension cable 132 is displaced relative to the guide component 131, thereby converting the shear force into tension and transmitting the tension to the movable rod 1331 connected to the flexible suspension cable 132, so that the movable rod 1331 is guided by the tension from the flexible suspension cable 132 to make axial displacement.

[0152] Of course, the orientation adjustments between photovoltaic system units in the photovoltaic system array 100 may be asynchronous for a short period of time, after which the asynchronous photovoltaic system units will adjust to the preset angle with a delay. In this case, although there will be deviations in the orientation angles between photovoltaic panel components, and these deviations will gradually increase, the deviations will gradually decrease after the remaining photovoltaic panel components adjust to the preset angles, until the asynchronous photovoltaic panel components also adjust to the preset angles, and the deviations will be eliminated.

[0153] If the moving rod 1331 fails to return to its original position after the deviation is eliminated, the main body of the flexible suspension cable 132 will not be subject to tension from both ends of the flexible suspension cable 132. Consequently, the main body of the flexible suspension cable 132 will droop over the guide assembly 131, making it prone to entanglement during subsequent orientation adjustments of the photovoltaic system array 100, potentially damaging the photovoltaic system units. Therefore, this application provides an elastic element 1332 over the main body of the moving rod 1331 to guide its return to its original position. The moving rod 1331 also includes a baffle at the other end of its main body. When an orientation angle deviation occurs between the photovoltaic panel components, the main body of the moving rod 1331 is guided by the tension from the flexible suspension cable 132 to make axial displacement, and the baffle compresses the elastic element 1332 in the compression direction. When the orientation angle between the photovoltaic panel components is eliminated, the elastic element 1332 returns to the original direction. The elastic force of the elastic element 1332 acts on the baffle, and the baffle drives the main body of the moving rod 1331 to make axial displacement until the elastic element 1332 returns to its original position or the moving rod 1331 resets.

[0154] It should be noted that the photovoltaic system units in the photovoltaic system array 100 are deployed relatively densely, making it difficult to detect photovoltaic system units whose angles do not conform to the preset angles. Therefore, the synchronous detection system unit 13 also includes a trigger mechanism 133 for sending prompt information. Typically, the trigger mechanism 133 is a prompt limit switch 1333. The trigger mechanism 133 is positioned in the compression direction of the elastic member 1332. Thus, once the main body of the moving rod 1331 is guided by the tension from the flexible suspension cable 132 to make axial displacement, the baffle triggers the prompt limit switch 1333, which then sends a prompt information, thereby reminding relevant personnel to perform adjustments and maintenance.

[0155] Of course, in the scenario where the orientation adjustment between photovoltaic system units in the photovoltaic system array 100 is asynchronous for a short period of time, and then the asynchronous photovoltaic system units adjust to the preset angle with a delay, although there will be a deviation in the orientation angle between the photovoltaic panel components, the deviation will be eliminated when the asynchronous photovoltaic panel components also adjust to the preset angle. In this case, no adjustment or maintenance is required. It can be seen that the sensitivity of the trigger mechanism 133 does not need to be set too high.

[0156] In specific application scenarios, the prompt limit switch 1333 is positioned in the compression direction of the elastic element 1332 and is spaced apart from the baffle position of the uncompressed elastic element 1332. This spaced distance defines the orientation angle deviation threshold. In other words, the spaced distance defines the sensitivity of the trigger mechanism 133; the longer the spaced distance, the lower the sensitivity of the trigger mechanism 133.

[0157] The following describes the implementation process of the prompt limit switch 1333 sending prompt information, taking the photovoltaic system array 100, which includes at least two photovoltaic system units, as an example. Specifically, the photovoltaic system array 100 is configured as follows:

[0158] When the first photovoltaic system unit 11 and the second photovoltaic system unit 12 adjust their orientation asynchronously, the distance between the guide component 131 set in the first photovoltaic system unit 11 and the guide component 131 set in the second photovoltaic system unit 12 increases, causing the flexible suspension cable 132 to pull the moving rod 1331 to make axial displacement along the compression direction of the elastic member 1332.

[0159] When the movable lever 1331 touches the prompt limit switch 1333, the prompt limit switch 1333 sends a prompt message.

[0160] Furthermore, the flexible suspension cable 132 has a length. Considering that if the length of the flexible suspension cable 132 is greater than the length of the photovoltaic system array 100, and the flexible suspension cable 132 is not subjected to tension from both ends, the flexible suspension cable 132 will droop over the guide component 131, easily becoming entangled during subsequent orientation adjustments of the photovoltaic system array 100, thereby damaging the photovoltaic system units, the flexible suspension cable 132 is configured with a length less than or equal to the length of the photovoltaic system array 100.

[0161] Furthermore, the flexible suspension cable 132 has a connected state. The flexible suspension cable 132 is configured such that when the main body of the flexible suspension cable 132 is subjected to tension from both ends of the flexible suspension cable 132, the connection state of the flexible suspension cable 132 is normal. When the main body of the flexible suspension cable 132 is not subjected to tension from both ends of the flexible suspension cable 132, the connection state of the flexible suspension cable 132 fails. The failure of the connection state of the flexible suspension cable 132 means that the connecting portion of the flexible suspension cable 132 may break, causing the main body of the flexible suspension cable 132 to droop over the guide assembly 131.

[0162] Furthermore, to detect the connection status of the flexible suspension cable 132, the triggering mechanism 133 also includes:

[0163] The detection limit switch 1334, located in the recovery direction of the elastic element 1332 and outside the deformation range of the elastic element 1332, is used to detect the connection status of the flexible suspension cable 132.

[0164] It is understood that the elastic element 1332 has a deformation stroke. Typically, the deformation stroke of the elastic element 1332 is defined by the distance of change from a first deformation state to a second deformation state. Preferably, the flexible suspension cable 132 is configured such that the sum of the length of the flexible suspension cable 132 and the deformation stroke of the elastic element 1332 is less than the length of the photovoltaic system array 100.

[0165] Thus, when the elastic element 1332 changes from the first degree of deformation state to the second degree of deformation state, the flexible suspension cable 132 becomes taut. At this time, the main body of the flexible suspension cable 132 is subjected to tension from both ends of the flexible suspension cable 132, and the connection state of the flexible suspension cable 132 is effective.

[0166] When the elastic element 1332 returns to its original state, it means that the connection part of the flexible suspension cable 132 is broken, which causes the baffle of the moving rod 1331 to touch the detection limit switch 1334. The detection limit switch 1334 sends a prompt message indicating that the connection state of the flexible suspension cable 132 has failed.

[0167] Furthermore, the flexible suspension cable 132 has a travel distance. The distance between the indication travel switch 1333 and the detection travel switch 1334 defines the travel distance of the flexible suspension cable 132. The flexible suspension cable 132 is configured such that the travel distance of the flexible suspension cable 132 is less than the deformation travel distance of the elastic element 1332, that is, the sum of the length of the flexible suspension cable 132 and the deformation travel distance of the elastic element 1332 is less than the length of the photovoltaic system array 100.

[0168] Furthermore, the triggering mechanism 133 is also used to detect the travel distance of the flexible suspension cable 132. The photovoltaic system array 100 is configured as follows:

[0169] When the connection of the flexible suspension cable 132 fails, the elastic force guides the moving rod 1331 of the elastic element 1332 to move axially along the recovery direction of the elastic element 1332 until the moving rod 1331 touches the detection limit switch 1334, and the prompt limit switch 1333 sends a prompt message.

[0170] Alternatively, when the travel of the flexible suspension cable 132 is greater than the deformation travel of the elastic element 1332, the elastic force of the elastic element 1332 guides the moving rod 1331 to make axial displacement along the recovery direction of the elastic element 1332 until the moving rod 1331 touches the detection limit switch 1334, and the prompt limit switch 1333 sends a prompt message.

[0171] Specifically, when the elastic element 1332 is in the first degree of deformation state, the baffle of the moving rod 1331 touches the prompt limit switch 1333, which sends a prompt message indicating that the orientation angle deviation between photovoltaic system units exceeds the orientation angle deviation threshold. When the elastic element 1332 is in the second degree of deformation state, the main body of the flexible suspension cable 132 is subjected to tension from both ends of the flexible suspension cable 132, the flexible suspension cable 132 is taut, and the connection state of the flexible suspension cable 132 is normal. When the elastic element 1332 returns to its original state, the elastic force of the elastic element 1332 guides the moving rod 1331 to make axial displacement along the return direction of the elastic element 1332 until the baffle of the moving rod 1331 touches the detection limit switch 1334, which sends a prompt message indicating that the connection state of the flexible suspension cable 132 has failed or the movement stroke of the flexible suspension cable 132 is greater than the deformation stroke of the elastic element 1332.

[0172] In summary, the photovoltaic system array 100 with synchronous detection system unit 13 provided in this application achieves the detection of orientation angle deviations between photovoltaic system units in the photovoltaic system array 100 at a lower cost by setting up the synchronous detection system unit 13, which includes a guide component 131, a flexible suspension cable 132, and a triggering mechanism 133. When there is an orientation angle deviation between photovoltaic system units in the photovoltaic system array 100, the triggering mechanism 133 sends a prompt message, thereby reminding relevant personnel to perform adjustments and maintenance, ensuring the timeliness of adjustments and maintenance, and maximizing the overall power generation capacity of the photovoltaic system array 100. Unlike electronic detection systems based on digital signals, the synchronous detection system unit 13 provided in this application is mainly based on physical signals, and its failure rate is lower than that of electronic detection systems based on digital signals. In application scenarios where photovoltaic system arrays 100 are deployed on a large scale, the maintenance cost of the synchronous detection system unit 13 is significantly lower.

[0173] Please refer to Figures 7 to 8 To address the technical problem that the orientation angle deviation between photovoltaic system units is difficult to detect, leading to a reduction in the overall power generation capacity of the photovoltaic system array, this application also provides a synchronous detection system 200.

[0174] The synchronous detection system 200 connects to multiple photovoltaic system units in the photovoltaic system array and is used to detect the orientation angle deviation between the photovoltaic system units in the photovoltaic system array; each photovoltaic system unit in the photovoltaic system array includes at least:

[0175] Photovoltaic panel modules are used to convert light energy into electrical energy;

[0176] An adjustable support assembly is provided for supporting the photovoltaic panel assembly and for adjusting the orientation of the photovoltaic panel assembly to receive light energy at an appropriate angle.

[0177] The following section uses the example of a photovoltaic system array comprising at least two photovoltaic system units to introduce the implementation scheme of the synchronous detection system 200.

[0178] The photovoltaic system array includes at least a first photovoltaic system unit and a second photovoltaic system unit;

[0179] The synchronous detection system 200 is connected to at least the first photovoltaic system unit and the second photovoltaic system unit, including:

[0180] Guide components 21 are respectively installed in the first photovoltaic system unit and the second photovoltaic system unit;

[0181] The flexible suspension cable 22 connected to the guide component 21 is used to reflect the orientation angle deviation of the first photovoltaic system unit and the second photovoltaic system unit;

[0182] The triggering mechanism 23, which is connected to the flexible suspension cable 22, is used to set the orientation angle deviation threshold.

[0183] When the orientation angle deviation between the first photovoltaic system unit and the second photovoltaic system unit exceeds the orientation angle deviation threshold, the triggering mechanism 23 is also used to send a prompt message.

[0184] It is understood that the flexible suspension cable 22 has at least a flexible suspension cable 22 body. Typically, the flexible suspension cable 22 is connected to the guide assembly 21 and the triggering mechanism 23, thus the flexible suspension cable 22 has a connecting portion and a flexible suspension cable 22 body. In specific application scenarios, the flexible suspension cable 22 body is typically a metal wire rope.

[0185] In another specific embodiment provided in this application, the flexible suspension cable 22 has at least a flexible suspension cable 22 body and an anchor disposed at one end of the flexible suspension cable 22 body. The anchor is used to establish an anchoring relationship between the flexible suspension cable 22 body and the guide component 21.

[0186] The guiding components 21 are respectively disposed in the first photovoltaic system unit and the second photovoltaic system unit, and allow the flexible suspension cable 22 to pass through, so that the flexible suspension cable 22 reflects the orientation angle deviation of the first photovoltaic system unit and the second photovoltaic system unit.

[0187] The working principle of the flexible suspension cable 22 in reflecting the orientation angle deviation of the first photovoltaic system unit and the second photovoltaic system unit is described below:

[0188] Guide components 21 are respectively disposed in the first photovoltaic system unit and the second photovoltaic system unit, and the main body of the flexible suspension cable 22 passes through the guide components 21. When the photovoltaic panel components of the first photovoltaic system unit and the photovoltaic panel components of the second photovoltaic system unit have the same orientation angle, the photovoltaic panel components of the first photovoltaic system unit and the photovoltaic panel components of the second photovoltaic system unit are parallel to each other. When the photovoltaic panel components have the same orientation angle, the distribution interval of the guide components 21 is the shortest, and the main body of the flexible suspension cable 22 is subjected to tension from both ends of the flexible suspension cable 22. However, when there is a deviation in the orientation angle of the photovoltaic panel components, the distribution interval of the guide components 21 becomes longer, and there is a height difference, which causes the main body of the flexible suspension cable 22 passing through the guide components 21 to be subjected to shear force. Since the main body of the flexible suspension cable 22 has a fixed length, when the main body of the flexible suspension cable 22 is subjected to shear force, the main body of the flexible suspension cable 22 is displaced relative to the guide components 21, thereby converting the shear force into tension force and transmitting the tension force to the triggering mechanism 23 connected to the flexible suspension cable 22. It can be seen that the main body of the flexible suspension cable 22 can convert the orientation angle deviation of the first photovoltaic system unit and the second photovoltaic system unit into tension force and transmit it to the triggering mechanism 23. This tension transmission is precisely how the flexible suspension cable 22 reflects the orientation angle deviation between the first photovoltaic system unit and the second photovoltaic system unit.

[0189] The guide component 21 supports the passage of the flexible suspension cable 22. In the application scenarios provided in this application, the guide component 21 can have various forms.

[0190] Furthermore, in one specific embodiment provided in this application, the guide component 21 provides an abutment portion that allows the flexible suspension cable 22 to pass through. The guide component 21 includes at least a first fixed pulley disposed on the photovoltaic panel assembly corresponding to the first photovoltaic system unit and a second fixed pulley disposed on the photovoltaic panel assembly corresponding to the second photovoltaic system unit.

[0191] The position of the pulley contact portion of the first fixed pulley is projected to the position of the pulley contact portion of the second fixed pulley;

[0192] One end of the flexible suspension cable 22 is fixed to the first fixed pulley;

[0193] The main body of the flexible suspension cable 22 passes sequentially through the pulley contact part of the first fixed pulley and the pulley contact part of the second fixed pulley;

[0194] The other end of the flexible suspension cable 22 is fixed to the triggering mechanism 23.

[0195] It is understood that in this specific embodiment, the guide component 21 includes a plurality of fixed pulleys, each of which provides a pulley contact portion to support the passage of the main body of the flexible suspension cable 22. Each photovoltaic panel of any photovoltaic system unit in the photovoltaic system array is provided with at least one fixed pulley. One end of the flexible suspension cable 22 is fixed to the fixed pulley of the photovoltaic system unit corresponding to the beginning of the photovoltaic system array. Specifically, the flexible suspension cable 22 can be attached to the fixed pulley of the photovoltaic system unit at the beginning of the array, forming the connecting portion of the flexible suspension cable 22.

[0196] Taking a photovoltaic system array comprising at least a first photovoltaic system unit and a second photovoltaic system unit as an example, the photovoltaic panel of the first photovoltaic system unit is equipped with a first fixed pulley, and the photovoltaic panel of the second photovoltaic system unit is equipped with a second fixed pulley. The position of the pulley contact portion of the first fixed pulley and the position of the pulley contact portion of the second fixed pulley are projected onto each other. In other words, the first and second fixed pulleys have the same shape, and the installation position of the first fixed pulley on the photovoltaic panel assembly of the first photovoltaic system unit is the same as the installation position of the second fixed pulley on the photovoltaic panel assembly of the second photovoltaic system unit. The first photovoltaic system unit can serve as the starting photovoltaic system unit of the photovoltaic system array. Thus, one end of the flexible suspension cable 22 is fixed to the first fixed pulley corresponding to the first photovoltaic system unit.

[0197] Furthermore, in another specific embodiment provided in this application, the guide component 21 provides a through hole allowing the flexible suspension cable 22 to pass through. The guide component 21 includes at least a first lug disposed on a photovoltaic panel assembly corresponding to the first photovoltaic system unit and a second lug disposed on a photovoltaic panel assembly corresponding to the second photovoltaic system unit.

[0198] The position of the through hole of the first lifting lug is projected to the position of the through hole of the second lifting lug;

[0199] One end of the flexible suspension cable 22 is fixed to the first lifting lug;

[0200] The main body of the flexible suspension cable 22 passes through the through hole of the first lifting lug and the through hole of the second lifting lug in sequence;

[0201] The other end of the flexible suspension cable 22 is fixed to the triggering mechanism 23.

[0202] It is understood that, in this specific embodiment, the guide component 21 includes several lugs, each lug having a through hole to support the passage of the main body of the flexible suspension cable 22. Each photovoltaic panel of any photovoltaic system unit in the photovoltaic system array is provided with at least one lug. One end of the flexible suspension cable 22 is fixed to the lug of the photovoltaic system unit at the beginning of the corresponding photovoltaic system array. Specifically, the flexible suspension cable 22 can be tied to the lug of the photovoltaic system unit at the beginning of the corresponding array, forming the connecting part of the flexible suspension cable 22. Alternatively, the anchor of the flexible suspension cable 22 can establish an anchoring relationship with the lug of the photovoltaic system unit at the beginning of the corresponding array.

[0203] Taking a photovoltaic system array comprising at least a first photovoltaic system unit and a second photovoltaic system unit as an example, the photovoltaic panel of the first photovoltaic system unit is provided with a first lifting lug, and the photovoltaic panel of the second photovoltaic system unit is provided with a second lifting lug. The through-hole positions of the first lifting lug and the through-hole positions of the second lifting lug are projected onto each other. In other words, the first and second lifting lugs have the same shape, and the installation positions of the first lifting lug and the second lifting lug on the photovoltaic panel assembly of the first photovoltaic system unit are the same. The first photovoltaic system unit can serve as the starting photovoltaic system unit of the photovoltaic system array. Thus, one end of the flexible suspension cable 22 is fixed to the first lifting lug corresponding to the first photovoltaic system unit.

[0204] Furthermore, the photovoltaic system array has a longitudinal array direction;

[0205] The first photovoltaic system unit serves as the starting point, the second photovoltaic system unit serves as the ending point, and the line connecting the first photovoltaic system unit and the second photovoltaic system unit defines the longitudinal array direction;

[0206] The flexible suspension cable 22 has an extension direction parallel to the longitudinal array direction.

[0207] It is understood that the guide component 21 defines the extension direction of the flexible suspension cable 22. In a scenario where a single fixed pulley or a single lug is provided on the photovoltaic panel of any photovoltaic system unit, the arrangement direction of the guide component 21 is naturally parallel to the extension direction of the photovoltaic system unit. However, in a scenario where multiple fixed pulleys or multiple lugs are provided on the photovoltaic panel of any photovoltaic system unit, this application preferably arranges the multiple fixed pulleys or multiple lugs in a longitudinal array. The multiple fixed pulleys or multiple lugs have a longitudinal array direction, and this longitudinal array direction is parallel to the longitudinal array direction of the photovoltaic system array. This minimizes the length of the flexible suspension cable 22 passing through the guide component 21, and ensures that the extension direction of the flexible suspension cable 22 is parallel to the longitudinal array direction.

[0208] The other end of the flexible suspension cable 22 is connected to a triggering mechanism 23, which is used to set an orientation angle deviation threshold. The triggering mechanism 23 can be set independently or attached to a photovoltaic system unit. Of course, in a specific embodiment where the triggering mechanism 23 is attached to a photovoltaic system unit, the triggering mechanism 23 is attached to the photovoltaic system unit at the end of the corresponding array. Taking an example where the photovoltaic system array includes at least a first photovoltaic system unit and a second photovoltaic system unit, with the first photovoltaic system unit serving as the starting photovoltaic system unit and the second photovoltaic system unit serving as the ending photovoltaic system unit, the triggering mechanism 23 can be set on the photovoltaic panel assembly of the second photovoltaic system unit or on the adjustable support assembly of the second photovoltaic system unit.

[0209] Please refer to Figures 9 to 10 The triggering mechanism 23 includes at least:

[0210] A movable rod 231 connected to the flexible suspension cable 22 and guided by the flexible suspension cable 22 to make axial displacement;

[0211] The elastic element 232 sleeved on the moving rod 231 is used to guide the moving rod 231 to reset;

[0212] A travel switch 233, positioned in the compression direction of the elastic element 232, is used to define an orientation angle deviation threshold.

[0213] It is understood that the movable rod 231 includes at least a main body of the movable rod 231 and a through hole disposed at one end of the main body of the movable rod 231. The through hole is connected to the flexible suspension cable 22. When there is a deviation in the orientation angle of the photovoltaic panel assembly, and the main body of the flexible suspension cable 22 is subjected to shear force, the main body of the flexible suspension cable 22 is displaced relative to the guide component 21, thereby converting the shear force into tension and transmitting the tension to the movable rod 231 connected to the flexible suspension cable 22, so that the movable rod 231 is guided by the tension from the flexible suspension cable 22 to make axial displacement.

[0214] Of course, the orientation adjustments between photovoltaic system units in a photovoltaic system array may be asynchronous for a short period of time, after which the asynchronous photovoltaic system units will adjust to the preset angle with a delay. In this case, although there will be deviations in the orientation angles between photovoltaic panel components, and these deviations will gradually increase, the deviations will gradually decrease after the remaining photovoltaic panel components adjust to the preset angles, until the asynchronous photovoltaic panel components also adjust to the preset angles, and the deviations will be eliminated.

[0215] If the moving rod 231 fails to return to its original position after the deviation is eliminated, the main body of the flexible suspension cable 22 will not be subjected to tension from both ends of the flexible suspension cable 22. Consequently, the main body of the flexible suspension cable 22 will droop over the guide component 21, making it prone to entanglement during subsequent orientation adjustments of the photovoltaic system array, potentially damaging the photovoltaic system units. Therefore, this application provides an elastic element 232 over the main body of the moving rod 231 to guide its return to its original position. The moving rod 231 also includes a baffle at the other end of its main body. When an orientation angle deviation occurs between the photovoltaic panel components, the main body of the moving rod 231 is guided by the tension from the flexible suspension cable 22 to make axial displacement, and the baffle compresses the elastic element 232 in the compression direction. When the orientation angle deviation between the photovoltaic panel components is eliminated, the elastic element 232 returns to its original position in the recovery direction. The elastic force of the elastic element 232 acts on the baffle, which causes the main body of the moving rod 231 to make axial displacement until the elastic element 232 returns to its original position or the moving rod 231 returns to its original position.

[0216] It should be noted that the photovoltaic system units in the photovoltaic system array are deployed relatively densely, making it difficult to detect photovoltaic system units whose angles do not conform to the preset angle. Therefore, the synchronous detection system 200 also includes a trigger mechanism 23 for sending prompt information. Typically, the trigger mechanism 23 is a prompt limit switch 233. The trigger mechanism 23 is positioned in the compression direction of the elastic member 232. Thus, once the main body of the moving rod 231 is guided by the tension from the flexible suspension cable 22 to make axial displacement, the baffle triggers the prompt limit switch 233, which then sends a prompt information, thereby reminding relevant personnel to perform adjustments and maintenance.

[0217] In specific application scenarios, the prompt limit switch 233 is positioned in the compression direction of the elastic element 232 and is spaced apart from the baffle position of the uncompressed elastic element 232. This spaced distance defines the orientation angle deviation threshold. In other words, the spaced distance defines the sensitivity of the trigger mechanism 23; the longer the spaced distance, the lower the sensitivity of the trigger mechanism 23.

[0218] The following describes the implementation process of the prompt limit switch 233 sending prompt information, taking the photovoltaic system array as an example, which includes at least two photovoltaic system units. Specifically, the photovoltaic system array is configured as follows:

[0219] When the first photovoltaic system unit and the second photovoltaic system unit adjust their orientation asynchronously, the distance between the guide component 21 set in the first photovoltaic system unit and the guide component 21 set in the second photovoltaic system unit increases, causing the flexible suspension cable 22 to pull the moving rod 231 to make axial displacement along the compression direction of the elastic member 232;

[0220] When the movable lever 231 touches the prompt limit switch 233, the prompt limit switch 233 sends a prompt message.

[0221] Furthermore, the flexible suspension cable 22 has a length. Considering that if the length of the flexible suspension cable 22 is greater than the length of the photovoltaic system array, and the flexible suspension cable 22 is not subjected to tension from both ends, the flexible suspension cable 22 will droop over the guide component 21, easily becoming entangled during subsequent orientation adjustments of the photovoltaic system array, thus damaging the photovoltaic system units. Therefore, the flexible suspension cable 22 is configured with a length less than or equal to the length of the photovoltaic system array.

[0222] Furthermore, the flexible suspension cable 22 has a connected state. The flexible suspension cable 22 is configured such that when the main body of the flexible suspension cable 22 is subjected to tension from both ends of the flexible suspension cable 22, the connection state of the flexible suspension cable 22 is normal. When the main body of the flexible suspension cable 22 is not subjected to tension from both ends of the flexible suspension cable 22, the connection state of the flexible suspension cable 22 fails. The failure of the connection state of the flexible suspension cable 22 means that the connecting portion of the flexible suspension cable 22 may break, causing the main body of the flexible suspension cable 22 to droop over the guide assembly 21.

[0223] Furthermore, to detect the connection status of the flexible suspension cable 22, the triggering mechanism 23 also includes:

[0224] The detection limit switch 234, located in the recovery direction of the elastic element 232 and outside the deformation range of the elastic element 232, is used to detect the connection status of the flexible suspension cable 22.

[0225] It is understood that the elastic element 232 has a deformation stroke. Typically, the deformation stroke of the elastic element 232 is defined by the distance of change from a first deformation state to a second deformation state. Preferably, the flexible suspension cable 22 is configured such that the sum of the length of the flexible suspension cable 22 and the deformation stroke of the elastic element 232 is less than the length of the photovoltaic system array.

[0226] Thus, when the elastic element 232 changes from the first degree of deformation state to the second degree of deformation state, the flexible suspension cable 22 becomes taut. At this time, the main body of the flexible suspension cable 22 is subjected to tension from both ends of the flexible suspension cable 22, and the connection state of the flexible suspension cable 22 is effective.

[0227] When the elastic element 232 returns to its original state, it means that the connection part of the flexible suspension cable 22 is broken, which causes the baffle of the moving rod 231 to touch the detection limit switch 234. The detection limit switch 234 sends a prompt message indicating that the connection state of the flexible suspension cable 22 has failed.

[0228] Furthermore, the flexible suspension cable 22 has a travel range. The distance between the indication travel switch 233 and the detection travel switch 234 defines the travel range of the flexible suspension cable 22. The sum of the length of the flexible suspension cable 22 and the deformation range of the elastic element 232 is less than the length of the photovoltaic system array.

[0229] Furthermore, the triggering mechanism 23 is also used to detect the travel distance of the flexible suspension cable 22. The photovoltaic system array is configured as follows:

[0230] When the connection of the flexible suspension cable 22 fails, the elastic force guides the moving rod 231 of the elastic element 232 to move axially along the recovery direction of the elastic element 232 until the moving rod 231 touches the detection limit switch 234, and the prompt limit switch 233 sends a prompt message.

[0231] Alternatively, when the travel of the flexible suspension cable 22 is greater than the deformation travel of the elastic element 232, the elastic force of the elastic element 232 guides the moving rod 231 to make axial displacement along the recovery direction of the elastic element 232 until the moving rod 231 touches the detection limit switch 234, and the prompt limit switch 233 sends a prompt message.

[0232] Specifically, when the elastic element 232 is in the first degree of deformation state, the baffle of the moving rod 231 touches the prompt limit switch 233, which sends a prompt message indicating that the orientation angle deviation between photovoltaic system units exceeds the orientation angle deviation threshold. When the elastic element 232 is in the second degree of deformation state, the main body of the flexible suspension cable 22 is subjected to tension from both ends of the flexible suspension cable 22, the flexible suspension cable 22 is taut, and the connection state of the flexible suspension cable 22 is normal. When the elastic element 232 returns to its original state, the elastic force of the elastic element 232 guides the moving rod 231 to make axial displacement along the return direction of the elastic element 232 until the baffle of the moving rod 231 touches the detection limit switch 234, which sends a prompt message indicating that the connection state of the flexible suspension cable 22 has failed or the movement stroke of the flexible suspension cable 22 is greater than the deformation stroke of the elastic element 232.

[0233] In summary, the synchronous detection system 200 provided in this application includes a guide component 21, a flexible suspension cable 22, and a triggering mechanism 23, enabling the detection of orientation angle deviations between photovoltaic system units in a photovoltaic system array at a relatively low cost. When an orientation angle deviation exists between photovoltaic system units in the photovoltaic system array, the triggering mechanism 23 sends a prompt message, thereby reminding relevant personnel to perform adjustments and maintenance, ensuring the timeliness of adjustments and maintenance, and maximizing the overall power generation capacity and revenue of the photovoltaic system array.
