Description

Technical Field

[0001] This utility model relates to the field of photovoltaics, and in particular to a photovoltaic tracking device. Background Technology

[0002] With the development of social technology, environmental pollution has become increasingly serious, and the contradiction between green mountains and clear waters and economic growth has become increasingly apparent. In order to ensure green mountains and clear waters while not affecting economic growth, it is an inevitable trend to reduce the proportion of petrochemical energy and increase the utilization of renewable energy.

[0003] Existing renewable energy sources, such as solar and wind power, are mostly concentrated in remote areas to reduce land costs, while energy consumption is concentrated in cities, which in turn leads to increased transportation costs.

[0004] To reduce energy transmission costs, distributed photovoltaic (PV) systems have been proposed to bring solar-powered photovoltaic devices closer to end users. However, in application scenarios suitable for distributed PV, such as roads, parks, and courtyards, increasing the power generation of individual PV devices has become the industry's primary goal.

[0005] To increase the power generation of a single photovoltaic (PV) device, some solutions have proposed photovoltaic tracking to align the PV panels as perpendicular to the sunlight as possible. Others have proposed directly increasing the area of ​​the PV panels in a single PV device by enlarging their size to capture more solar energy, thereby effectively increasing the power generation of the single PV device.

[0006] However, existing tracking brackets either connect the photovoltaic panels to the bracket via the back of the panels, which greatly limits the application scenarios of the photovoltaic system, meaning that the photovoltaic panels can only be installed at the very top of the tracking bracket to track sunlight; or they connect the photovoltaic panels to one side or the back of the bracket. In this case, the weight of the photovoltaic panels has a significant impact on the connection point, and when the photovoltaic panels are exposed to wind, the connection point can easily be damaged, or even the entire device can be destroyed.

[0007] Therefore, while increasing the size of photovoltaic panels, how to connect the enlarged photovoltaic panels with tracking devices in a more reasonable way is a key issue that urgently needs to be solved. Utility Model Content

[0008] This utility model first proposes a photovoltaic tracking device to solve the above-mentioned problems caused by connecting the photovoltaic panel to the existing tracking bracket after the area of ​​the photovoltaic panel is increased; secondly, it proposes a photovoltaic tracking device.

[0009] As a first aspect of this utility model, a photovoltaic tracking device is proposed, characterized in that:

[0010] Includes a pillar, a first photovoltaic panel, a rotating component, and a first folding component;

[0011] The rotating assembly includes a rotating part and a fixed part. The fixed part is fixedly connected to the column. The rotating part can rotate around the column relative to the fixed part. The rotating assembly is used to drive the first photovoltaic panel and the first folding assembly to rotate around the column.

[0012] The first folding assembly includes a first push rod and a support rod. The support rod is divided into a head and a tail. The head of the support rod is hinged to the rotating part, and the tail of the support rod is connected to the part of the first photovoltaic panel away from the column. The first folding assembly is used to drive the first photovoltaic panel to rotate. One end of the first push rod is hinged to the rotating part, and the other end of the first push rod is hinged to the support rod.

[0013] Preferably, a first middle section is provided between the head and the tail of the support rod, and the first push rod is hinged to the first middle section of the support rod;

[0014] Alternatively, the first push rod is hinged to the end of the support rod.

[0015] Preferably, the support rod further includes a second middle section between the head and the tail, and the first folding assembly further includes a second push rod. One end of the second push rod is hinged to the second middle section of the support rod, the tail of the support rod is hinged to the first photovoltaic panel, and the other end of the support rod is hinged to the first photovoltaic panel.

[0016] Preferably, the end of the support rod is hinged to the side of the first photovoltaic panel, and the other end of the second push rod is hinged to the side of the first photovoltaic panel.

[0017] Preferably, it also includes a bracket, the head of the support rod is fixedly connected to the rotating part through the bracket, the overall structure of the bracket is "X" shaped, and it is fixedly connected to the rotating part through its central part.

[0018] Preferably, the device further includes a second folding component and a second photovoltaic panel. One end of the second folding component is connected to the first photovoltaic panel, and the other end is connected to the second photovoltaic panel. The second folding component is provided with a second axis, and the second folding component can drive the second photovoltaic panel to rotate around the second axis.

[0019] Preferably, the rotating component is driven by a helical drive.

[0020] Preferably, the number of the first folding components is at least two sets, and the at least two sets of the first folding components are symmetrically arranged on both sides of the column.

[0021] Preferably, at least two sets of the first photovoltaic panels are respectively disposed on the first folding components on both sides of the column;

[0022] The photovoltaic tracking device also includes a plug and a plug slot. When the plug and the plug slot are engaged, the first photovoltaic panels on both sides of the column are located on the same plane.

[0023] Preferably, the end of the plug portion is provided with a first guide area, and the plug interface of the plug groove is provided with a second guide area.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. After increasing the area of ​​the photovoltaic panel, the photovoltaic tracking device often requires an increased power source to operate normally. In this invention, the first photovoltaic panel is connected to the end of the support rod. When the first folding component drives the first photovoltaic panel to rotate, the first push rod, while pushing the support rod, transmits the force to the first photovoltaic panel through the end of the support rod. This reduces the power source requirement of the photovoltaic tracking device after increasing the photovoltaic panel area, thus lowering the cost.

[0026] 2. By incorporating a rotating component and a first folding component, the photovoltaic panel can rotate to achieve solar azimuth and solar altitude angle tracking, i.e., dual-axis tracking. This increases the amount of sunlight absorbed by the solar energy device, thereby improving solar power generation efficiency. The first push rod's travel distance during operation should not be too large, as an excessively long travel distance reduces the overall structural stability. Therefore, the first push rod typically only rotates the first photovoltaic panel by a small angle, making it impossible to ensure the photovoltaic panel is perpendicular to the sunlight at all times in some high-latitude regions. In this case, since the first folding component also includes a second push rod, the second push rod can further increase the rotation angle of the first photovoltaic panel based on the first push rod's travel distance. This allows the photovoltaic tracking device to achieve complete tracking of the solar altitude angle in any region, further improving solar power generation efficiency.

[0027] 3. When the photovoltaic panels are in the folded state, the photovoltaic panels on both sides of the column are folded up close to the column and perpendicular to the ground plane. This can effectively avoid the adverse effects of extreme weather conditions such as rain and snow on the photovoltaic tracking device, enhance the overall adaptability, stability and durability of the photovoltaic device, and ensure that the photovoltaic system can maintain high efficiency and stable energy conversion efficiency under various environmental conditions.

[0028] 4. By incorporating a second folding component, the photovoltaic tracking device can enter a secondary folding state when photovoltaic power generation is not required or when encountering adverse conditions. The secondary folding state refers to the two second photovoltaic panels rotating around their respective first and second photovoltaic panels along an axis until the light-receiving surfaces (photovoltaic power generation surfaces) of the first and second photovoltaic panels are facing each other. At this point, the second photovoltaic panels completely block the light-receiving surface of the first photovoltaic panels. Therefore, in the second fold, most of the photovoltaic power generation surfaces of the first and second photovoltaic panels are mutually blocked, which greatly protects the first and second photovoltaic panels. Furthermore, in adverse external conditions such as rain, snow, or dust, the impact of these conditions on the photovoltaic tracking device proposed in this invention can be further reduced.

[0029] 5. The strut is L-shaped, divided into a first part and a second part by the inflection point of the L-shape. The first part includes the end of the strut, and the second part includes the beginning, a first middle part, and a second middle part. The shape of the L-shaped strut and the placement of the first and second middle parts allow the first and second push rods to adjust the rotation of the first photovoltaic panel by only advancing or retracting a short distance during their reciprocating pushing and retracting movements. Furthermore, in applications using photovoltaic tracking devices with paired photovoltaic panels on both sides, the gap between the photovoltaic panels on both sides can be eliminated, preventing shading problems caused by photovoltaic panels at different positions on both sides during operation and improving photovoltaic power generation efficiency.

[0030] 6. This utility model features a connector on the first side of one photovoltaic panel and a slot on the first side of the other. Upon startup, both photovoltaic panels unfold simultaneously, with the connectors engaging with the slots to form a sliding structure. During photovoltaic tracking, the angles of the two panels adjust according to changes in sunlight. Simultaneously, the distance between the first sides of the two panels changes, but the connectors and slots ensure that the two panels function as a single unit, further guaranteeing that the light-receiving surfaces of the two panels remain on the same plane and increasing the stability of the photovoltaic tracking device.

[0031] 7. In various embodiments proposed in this utility model, the hinge positions of the support rod and the second push rod with the first photovoltaic panel are set far away from the column. When the photovoltaic tracking device performs solar tracking, there is only a small gap or even no gap between the first photovoltaic panels on both sides. Such a setting can increase the photovoltaic power generation area and aesthetics to a certain extent. Attached Figure Description

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] A photovoltaic tracking device is proposed, in situations such as Figures 1 to 10In some embodiments shown, the components include a column 1, a first photovoltaic panel 5, a rotating assembly 3, and a first folding assembly 4. The rotating assembly 3 has a first axis and includes a rotating part and a fixed part, which are capable of rotating relative to each other around the first axis. The first axis is parallel to the column 1, and the fixed part is fixedly connected to the column 1. The first folding assembly 4 includes a first push rod 41 and a support rod 42. The support rod 42 is sequentially divided into a head, a first middle part, and a tail. The head of the support rod 42 is hinged to the rotating part, and the tail of the support rod 42 is hinged to the first push rod 41. One end of the first push rod 41 is hinged to the rotating part, and the other end of the first push rod 41 is hinged to the support rod 42.

[0047] Regarding the hinge position between the first push rod 41 and the support rod 42, as follows: Figure 4 In the first embodiment of the photovoltaic tracking device shown, the first push rod 41 is hinged to the first middle part of the support rod 42. During its extension and retraction, the first push rod 41 drives the first photovoltaic panel 5 to rotate via the first middle part hinged to the support rod 42. The rotation of the first photovoltaic panel 5 is around the hinge axis between the head of the support rod and the rotating part. In other embodiments, such as... Figure 8 and Figure 9 In the second embodiment of the photovoltaic tracking device shown, the difference in the connection position of the first push rod 41 compared with the first photovoltaic tracking device is that one end of the first push rod 41 is hinged to the rotating part, and the other end of the first push rod 41 is hinged to the end of the support rod 42. The motion state is similar to that of the first embodiment, and will not be described in detail here.

[0048] The first push rod 41 in the photovoltaic tracking device functions to push the support rod 42. This not only allows the first photovoltaic panel 5 to rotate, thereby achieving continuous tracking of the solar altitude angle to maximize solar energy collection efficiency, but also allows the first photovoltaic panel 5 to be pushed to... Figure 2 The folded state shown. When the photovoltaic panel is in such a state... Figure 2 When folded as shown, the photovoltaic panels on both sides of the column 1 are folded up close to the column 1 and perpendicular to the ground plane. This effectively avoids the adverse effects of extreme weather conditions such as rain and snow on the photovoltaic tracking device, enhances the overall adaptability, stability and durability of the photovoltaic device, and ensures that the photovoltaic system can maintain high efficiency and stable energy conversion efficiency under various environmental conditions.

[0049] In some embodiments, a second middle section is also included between the head and tail of the strut 42, such as... Figure 5Specifically, between the head and the first middle section of the support rod 42, the first folding assembly 4 also includes a second push rod 43. One end of the second push rod 43 is hinged to the second middle section of the support rod 42, and the other end is hinged to the first photovoltaic panel 5. The second middle section can also be located between the tail and the first middle section of the support rod 42, or directly located at the head of the support rod 42, or directly located on the first middle section of the support rod.

[0050] It should be noted that the strut 42 can be divided into a head, a first middle section and a tail section according to its length. The relative positions of the head, the first middle section and the tail section can also be adjusted according to actual needs to meet specific implementation requirements. For example, when the first photovoltaic panel 5 is long and heavy, the first middle section is close to the tail section. At this time, the torque of the force applied by the first push rod 41 on the strut 42 is larger, making it easier to push the heavier first photovoltaic panel 5.

[0051] Furthermore, in some implementations, in such... Figure 4 In some embodiments shown, the support rod 42 is L-shaped, divided into a first part and a second part by the inflection point of the L-shape. The first part includes the end of the support rod 42, and the second part includes the head, a first middle part, and a second middle part of the support rod 42. The shape of the L-shaped support rod 42 and the placement of the first and second middle parts allow the first push rod 41 and the second push rod 43 to adjust the rotation of the first photovoltaic panel 5 by only advancing or retracting a short distance during their reciprocating pushing and retracting movements. Moreover, in Figure 3 and Figure 4 The application uses photovoltaic tracking devices arranged in pairs on both sides, which can eliminate the gap between the photovoltaic panels on both sides during the tracking of sunlight, so that there will be no shading problem between photovoltaic panels at different positions on both sides during operation, thus improving the photovoltaic power generation efficiency.

[0052] In some embodiments, the hinge positions of the first photovoltaic panel 5, the support rod 42, and the second push rod 43 with the first photovoltaic panel 5 are set far away from the column 1. When the photovoltaic tracking device performs solar tracking, there is only a small gap or even no gap between the first photovoltaic panels 5 on both sides. Such a setting can increase the photovoltaic power generation area and aesthetics to a certain extent.

[0053] exist Figures 1 to 5 In the first embodiment shown, the end of the support rod 42 is hinged to the back of the first photovoltaic panel 5, and one end of the second push rod 43 is hinged to the second middle part of the support rod 42, while the other end is hinged to the back of the first photovoltaic panel 5. Furthermore, the support rod 42 and / or the second push rod 43 can be positioned at the center of the back of the first photovoltaic panel 5 (this can be flexibly adjusted when other photovoltaic panels are connected, and will not be elaborated further below). When the first photovoltaic panel 5 is subjected to external wind forces, the connection point of the first photovoltaic panel 5 is less likely to be damaged, making the photovoltaic tracking device more stable and reliable.

[0054] In such Figures 6 to 9 In the second embodiment shown, the end of the support rod 42 is hinged to the side of the first photovoltaic panel 5, and one end of the second push rod 43 is hinged to the second middle part of the support rod 42, and the other end is hinged to the side of the first photovoltaic panel 5. The rotation angle of the first photovoltaic panel 5 is controlled by the first folding assembly 4. In the first folding assembly 4, the length of the support rod 42 should not be too short; otherwise, the first push rod 42 will require a large force to push the support rod 42 with a smaller lever arm. The above arrangement ensures that when the first folding assembly 4 drives the first photovoltaic panel 5 to rotate, the first folding assembly 4 can... Figure 6 The light-receiving surface of the first photovoltaic panel 5, as shown, increases the rotation angle range of the first photovoltaic panel 5 while ensuring a certain length of the support rod 42, thereby improving the ability of the photovoltaic tracking device to track sunlight and increasing the overall power generation.

[0055] In some embodiments, the strut 42 and / or the second push rod 43 are directly hinged to both sides of the frame of the first photovoltaic panel 5, which means that the first photovoltaic panel 5 can be connected without additional installation processing or reinforcement, improving the convenience of the connection method, simplifying the processing and assembly process, and thus reducing costs.

[0056] By incorporating a rotating component 3 and a first folding component 4, the solar tracking device of this invention can rotate the solar azimuth and solar altitude angles to track the directions of these angles. This increases the amount of sunlight absorbed by the solar device, thereby improving solar power generation efficiency. However, it should be noted that the set stroke of the first push rod 41 during operation should not be too large, as an excessively long stroke may reduce the stability of the overall structure. Therefore, the first push rod 41 can typically only rotate the first photovoltaic panel 5 by a small angle, making it impossible to ensure that sunlight is perpendicular to the photovoltaic panel at all times in some high-latitude regions. In this case, since the first folding component 4 also includes a second push rod 43, the second push rod 43 can further increase the rotation angle of the first photovoltaic panel 5 based on the stroke of the first push rod 41, enabling the solar tracking device to achieve complete tracking of the solar altitude angle in any region, further improving solar power generation efficiency.

[0057] In some embodiments, the photovoltaic tracking device further includes a bracket 2, and the support rod 42 is fixedly connected to the rotating part through the bracket 2. It should be noted that in other embodiments of this example, the hinge connection with the rotating part can be understood as an indirect hinge connection through the bracket 2. In such cases… Figure 4 In some embodiments shown, the bracket 2 is arranged in an "X" shape and is fixedly connected to the rotating part through its central part. This structure can improve the overall stability and make the photovoltaic tracking device operate more reliably.

[0058] In such Figures 1 to 5 In some embodiments shown, the photovoltaic tracking device includes two sets of first folding components 4 and two sets of first photovoltaic panels 5. The first folding components 4 and the first photovoltaic panels 5 are arranged in pairs on both sides of the column 1, which can balance the pressure generated by the components other than the column 1 on the column 1 and improve the stability of the device. Furthermore, second photovoltaic panels 6 can also be arranged on both sides.

[0059] In some embodiments, multiple sets of first folding components 4 are also included. These multiple sets of first folding components 4 are disposed on one side of the column 1, and are respectively hinged to the first smooth plate and the rotating part. In such cases... Figure 3 In the embodiment shown, two sets of first folding components 4 are provided, which can synchronously drive the first photovoltaic panel 5 to rotate and track or fold up, and can also improve the strength of the photovoltaic tracking device and enhance the overall stability and reliability.

[0060] The first push rod 41 and the second push rod 43 are telescopic actuating components (such as electric push rods). The first photovoltaic panel 5 rotates by the reciprocating extension and retraction of the first push rod 41. In embodiments without multiple sets of first folding components 4, in order to avoid the problem of poor balance, it is necessary to add auxiliary connecting rods to keep it stable. The same applies to the second push rod 43.

[0061] In some embodiments, a second folding assembly and a second photovoltaic panel 6 are also included. One end of the second folding assembly is connected to the first photovoltaic panel 5, and the other end is connected to the second photovoltaic panel 6. The second folding assembly has a second axis, which is the line between the first photovoltaic panel 5 and the second photovoltaic panel 6. The second folding assembly can drive the second photovoltaic panel 6 to rotate around the second axis. Figure 1 and Figure 2 In the illustrated embodiment, by providing a second folding component, the photovoltaic tracking device can enter a secondary folding state when photovoltaic power generation is not required or when encountering adverse conditions. The secondary folding state refers to the two second photovoltaic panels 6 rotating around their respective second axes until the light-receiving surfaces (photovoltaic power generation surfaces) of the first photovoltaic panel 5 and the second photovoltaic panel 6 are positioned opposite each other. At this time, the second photovoltaic panels 6 can completely block the light-receiving surface of the first photovoltaic panel 5. Therefore, in the second fold, most of the photovoltaic power generation surfaces of the first photovoltaic panel 5 and the second photovoltaic panel 6 are mutually blocked, which can greatly protect the first photovoltaic panel 5 and the second photovoltaic panel 6. In the event of adverse external conditions such as rain, snow, or dust, the impact of rain, snow, or dust on the photovoltaic tracking device proposed in this invention can be further reduced.

[0062] The rotating component 3 drives the first photovoltaic panel 5 (and the second photovoltaic panel 6) to rotate around the first axis, enabling the solar tracking device to track the solar azimuth angle. In some embodiments, the rotating component 3 and the second folding component are driven by a helical drive, which is typically achieved through a helical drive assembly of a helical pair. Regarding the structure of the rotating component 3 and the second folding component, both components can be composed of helical drive assemblies, or one of them can be composed of a helical drive assembly. The specific structure of the rotating component 3 and / or the second folding component has been disclosed in several patents of this company with application numbers CN2022116054218, CN2022116053126, CN2023230217106, CN202323021713X, and CN2023114847154, and therefore will not be elaborated further.

[0063] exist Figure 3 In the embodiment shown, the first axis of the rotating component 3 is coaxial with the column 1, the fixed part of the rotating component 3 is fixedly connected to the column 1, the rotating part of the rotating component 3 is fixedly connected to the bracket 2, and the rotating component 3 can drive the bracket 2 to rotate around the column 1.

[0064] In some embodiments, the first push rod 41 and the second push rod 43 are respectively electric push rods, pneumatic push rods, or hydraulic push rods. These two types of push rods each have their unique advantages and applicable scenarios. Electric push rods, as devices that use an electric motor as a power source and convert electrical energy into mechanical energy through a transmission device to achieve push-pull actions, are typically used in environments where the push-pull force requirement is not high, but where operational convenience and electrical control requirements are high. Hydraulic push rods, on the other hand, rely on pressurized oil in a hydraulic system as a power source, converting hydraulic energy into mechanical energy through the action of a hydraulic cylinder to complete the push-pull operation. Their strong load-bearing capacity and adaptability make hydraulic push rods superior in places requiring large push-pull forces or in harsh environments. Pneumatic push rods use compressed air as a power source, driving the piston movement through a cylinder to drive the push rod action. They possess the characteristics of fast response speed and no pollution associated with pneumatic systems. Therefore, both electric and hydraulic push rods can be flexibly applied to diverse implementation scenarios according to actual needs to serve the photovoltaic tracking device proposed in this application.

[0065] In some embodiments, the number of first folding components 4 is at least two sets, and at least two sets of first folding components 4 are symmetrically arranged on both sides of the column 1. For example... Figures 1 to 5 In the embodiment shown, two sets of first folding components 4 are symmetrically arranged on both sides of the column 1 by means of "X"-shaped brackets 2. Two sets of first folding components 4 are provided on one side of the column 1. The two sets of first folding components 4 support and control the rotation of the first photovoltaic panel 5, thereby improving the stability of the transmission.

[0066] Furthermore, in this embodiment, to increase the stability of the two first photovoltaic panels 5, such as... Figure 10 As shown, the first photovoltaic panels 5, which are respectively disposed on both sides of the column 1, have a plug-in part 21 on the first side of one and a plug-in groove 22 that cooperates with the plug-in part 21 on the first side of the other.

[0067] The plug-in part 21 and the plug-in slot 22 can be directly set on the first photovoltaic panel 5 on both sides, or they can be connected to the first photovoltaic panel 5 through other intermediate parts and then cooperate with the plug-in part 21 or the plug-in slot 22.

[0068] It should be noted that when the first photovoltaic panel 5 starts to generate electricity, the two first photovoltaic panels 5 are unfolded at the same time. At the same time as unfolding, the insertion part 21 of the two first photovoltaic panels 5 is connected to the insertion slot 22. When the two first photovoltaic panels 5 are in a horizontal state, the distance between the two first photovoltaic panels 5 is the largest, and the insertion part 21 and the insertion slot 22 form a sliding structure.

[0069] During the dynamic tracking of sunlight by the photovoltaic tracking device, the two first photovoltaic panels 5 work together through the insertion part 21 and the insertion slot 22 to finely adjust their tilt angle to maximize sunlight reception. Although the relative distance between them adjusts with the angle, thanks to the sliding engagement of the insertion part 21 and the insertion slot 22, the two first photovoltaic panels 5 remain a stable whole, ensuring that their light-receiving surfaces are highly consistent and on the same horizontal plane. This not only optimizes the light-receiving efficiency of the first photovoltaic panels 5 but also significantly enhances the overall stability and reliability of the photovoltaic tracking device.

[0070] Furthermore, in this embodiment, while the two first photovoltaic panels 5 are unfolded, to facilitate the connection between the insertion part 21 and the insertion slot 22, as follows: Figure 10 As shown, the end of the plug-in portion 21 is provided with a first guide area 211, and the plug-in interface of the plug-in groove 22 is provided with a second guide area.
