Description

Technical Field

[0001] This utility model relates to the field of photovoltaic brackets, specifically providing a photovoltaic bracket and a photovoltaic power generation system. Background Technology

[0002] Currently, flexible support systems are mainly used in mountainous areas, fishponds, and sewage treatment plants. Most of them have a fixed tilt angle, which affects the power generation of the modules and reduces the power generation revenue. In terms of structural composition, existing photovoltaic support systems usually include side columns and central columns. The structure of side columns plus central columns leads to higher pile foundation costs, greater construction difficulty, and longer construction period, and also puts forward higher requirements for the installation of other subsequent structures.

[0003] For sites such as sewage treatment plants, fish ponds, agricultural land, and breeding farms, traditional flexible brackets generally require a clearance of more than five meters due to limitations in working space and the underlying building. This high clearance brings inconvenience to installation, requiring workers to use equipment or be suspended in the air to carry out the work. This further increases the installation cost of photovoltaic brackets, reduces the installation efficiency of photovoltaic brackets, and increases the difficulty of later maintenance. In addition, the safety of construction workers is difficult to guarantee.

[0004] In addition, existing flexible photovoltaic (PV) brackets do not have good solutions for dealing with extreme weather such as strong winds and hail, and PV brackets and PV panels are easily damaged under extreme weather conditions.

[0005] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0009] In the specific embodiment of the photovoltaic support described above, the photovoltaic support further includes: a first magnetic element disposed on the sliding rod; and a second magnetic element disposed vertically on one side of the first magnetic element, wherein the magnetic force generated between the second magnetic element and the first magnetic element is used to push the sliding rod to slide within the groove.

[0010] In the above-described specific embodiment of the photovoltaic support, the photovoltaic support further includes: a third magnetic element disposed on the sliding end; and a fourth magnetic element disposed in the groove. The third magnetic element and the fourth magnetic element have the same magnetism, and the magnetic force generated between the third magnetic element and the fourth magnetic element separates the sliding end from the inner wall of the groove.

[0011] In the specific embodiment of the photovoltaic support described above, the linkage assembly further includes: a second linkage, which is disposed on the first rotating shaft and rotates with the first rotating shaft; one end of the support bracket is disposed on the second linkage and is disposed on the first rotating shaft via the second linkage.

[0012] In the specific embodiment of the photovoltaic support described above, the linkage assembly further includes a third linkage, which is disposed on one side of the second linkage and is used to provide the second linkage with support force for the load-bearing support.

[0013] In the specific embodiment with photovoltaic support described above, the linkage assembly further includes: a third rotating shaft, the axis of which is coaxial with the axis of the second rotating shaft; a fourth rotating shaft, the axis of which is coaxial with the axis of the first rotating shaft; the second link, the third link, and the sliding rod are each provided with a mutually perpendicular head end and a tail end; the head ends and tail ends of the first link, the second link, the third link, and the sliding rod are sequentially connected in a ring around each other; the tail end of the first link and the head end of the second link are rotatably connected via the first rotating shaft; the tail end of the sliding rod and the head end of the first link are connected via the second rotating shaft; the head end of the third link and the tail end of the second link are rotatably connected via the third rotating shaft; and the tail end of the third link and the head end of the sliding rod are rotatably connected via the fourth rotating shaft.

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0027] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Furthermore, in order to more clearly demonstrate the core technical solution of this utility model, the description of the known structure of photovoltaic modules is omitted in the following description. However, this omission is only for the convenience of description and does not mean that photovoltaic modules can be without these structures.

[0030] like Figure 1-7 As shown, this utility model proposes a photovoltaic support bracket, including: a support column 1; a mounting frame 2, which is disposed on the support column 1 and the support column 1 is used to support the mounting frame 2; a connecting rod assembly, which includes a first rotating shaft 3 that is rotatably disposed on the mounting frame 2 in a vertical direction; and a load-bearing bracket 4, which is used to install photovoltaic modules 20. One end of the load-bearing bracket 4 is disposed on the first rotating shaft 3 and rotates with the first rotating shaft 3. After the first rotating shaft 3 rotates, it drives the other end of the load-bearing bracket 4 to move closer to the mounting frame 2 or unfold from one side of the mounting frame 2.

[0031] In this embodiment, to simultaneously address the problems of high cost, difficult construction, and poor resistance to extreme weather associated with existing photovoltaic support pile foundations, the structure of the photovoltaic support is improved. Support columns 1 support the mounting frame 2 from below, and load-bearing supports 4 are then installed on the mounting frame 2, reducing the number of side columns and lowering the pile foundation cost. To enable the mounting frame 2 to support more load-bearing supports 4, the length of the mounting frame 2 can be extended, with multiple load-bearing supports 4 spaced apart along its length. Simultaneously, multiple support columns 1 are installed below the mounting frame 2 along its length. To avoid an imbalance caused by too many load-bearing supports 4 installed on one side of the mounting frame 2, the load-bearing supports 4 can be symmetrically installed on both sides of the mounting frame 2, such as... Figure 3 As shown, with fewer side columns, only support column 1 needs to be constructed, which reduces the amount and difficulty of construction and improves construction efficiency.

[0032] In addition to supporting the mounting frame 2 solely with the support column 1, this embodiment also includes a first rotating shaft 3 (the vertical direction is indicated by X in the figure). The bearing bracket 4 is mounted on the mounting frame 2 via the first rotating shaft 3. Rotating the first rotating shaft 3 changes the state of the bearing bracket 4 relative to the mounting frame 2. In calm weather, the first rotating shaft 3 is driven to rotate forward by an extension drive device (not shown in the figure), causing the bearing bracket 4 to unfold from one side of the mounting frame 2, and the photovoltaic module 20 on the bearing bracket 4 generates electricity normally. In extreme weather such as hail and strong winds, the first rotating shaft 3 is driven to rotate in the opposite direction by the extension drive device, causing the bearing bracket 4 to move closer to the mounting frame 2 from the unfolded state, and in turn, causing the photovoltaic module 20 to move closer to the mounting frame 2, so that the back of the photovoltaic module 20 is in a close contact with the side of the mounting frame 2 at a certain angle, reducing the windward area of ​​the photovoltaic bracket and the photovoltaic module 20. When the photovoltaic module 20 is mounted vertically on the bearing bracket 4, the area of ​​the photovoltaic module 20 subjected to hail impact can also be reduced, maximizing the protection of the photovoltaic bracket and the photovoltaic module 20.

[0033] The structure of this utility model, which supports the mounting frame 2 only through the support column 1, reduces the number of pile foundations and costs. When combined with the first rotating shaft 3, it can also reduce the damage to the photovoltaic support and photovoltaic modules caused by extreme weather. In addition, for scenarios such as fish ponds and agricultural land, the photovoltaic support in this utility model uses fewer piles and the structural feature that allows the photovoltaic modules 20 to move closer to the mounting frame 2 makes the working space below more flexible and reduces the restrictions on clearance.

[0034] The mounting frame 2 has installation space, allowing construction personnel to install the tracking components and the first rotating shaft 3, as well as perform subsequent maintenance. Since rotating the first rotating shaft 3 allows the support bracket 4 to move closer to the mounting frame 2, after installing the support bracket 4 on the first rotating shaft 3 with the aid of a crane, the first rotating shaft 3 can be rotated to bring the support bracket 4 closer to the mounting frame 2. Then, the photovoltaic module 20 can be laid on the support bracket 4 on the mounting frame 2. When maintenance of the photovoltaic module 20 or the support bracket 4 is required later, rotating the first rotating shaft 3 brings the support bracket 4 closer to the mounting frame 2, and then disassembling and repairing the photovoltaic module 20 and the support bracket 4 on the mounting frame 2. The structure of the photovoltaic module in this invention reduces the time spent working at heights, ensures worker safety, and improves the safety and convenience of installation and subsequent maintenance.

[0035] Furthermore, such as Figures 3-6As shown, in this embodiment, in order to improve the power generation of the photovoltaic module 20, the linkage assembly further includes: a second rotating shaft 5 and a first connecting rod 6. The second rotating shaft 5 is rotatably mounted on the mounting frame 2 in a horizontal direction. A tracking drive device (not shown in the figure) is used to drive the second rotating shaft 5 to rotate. The extension drive device and the tracking drive device can be motors. Since the axial direction of the first rotating shaft 3 is perpendicular to the axial direction of the second rotating shaft 5, the first connecting rod 6 is provided with a head end and a tail end that are perpendicular to each other. The head end is provided on the second rotating shaft 5 and rotates with the second rotating shaft 5. The tail end is provided with the first rotating shaft 3. The first rotating shaft 36 is mounted on the mounting frame 2 through the first connecting rod and the second rotating shaft 5. The second rotating shaft 5 is configured to drive the first rotating shaft 3 and the support bracket 4 to rotate in the direction of the sun's rotation after it rotates. In the diagram, the Y-direction represents the axial direction of the second rotating shaft 5, which is in the north-south direction. When the second rotating shaft 5 rotates, it drives the support bracket 4 to rotate from east to west. At the same time, the support bracket 4 rotates from east to west, driving the photovoltaic module 20 to rotate from east to west as well, so as to achieve solar tracking. During the tracking process, the tilt angle between the photovoltaic module 20 and the ground changes continuously, so that the photovoltaic module 20 can receive light energy to the maximum extent and convert it into electrical energy, thereby increasing the power generation.

[0036] In addition, by rotating the second rotating shaft 5, the tilt angle between the photovoltaic module 20 on the support bracket 4 and the ground can be controlled. In extreme weather conditions, the photovoltaic module 20 can be controlled to be perpendicular to the ground to reduce the range of the photovoltaic module 20 being impacted by hail.

[0037] Furthermore, such as Figure 6 and Figure 7 As shown, for ease of later maintenance and replacement, the photovoltaic bracket also includes: a guide 7, which is mounted on the mounting frame 2 and has a vertically extending groove 8, with the top of the groove 8 serving as an outlet; a sliding rod 10, which has a sliding end 11 that slides into or out of the groove 8 from the outlet and is slidably mounted within the groove 8; and a second rotating shaft 5 mounted on the sliding rod 10 and sliding with the sliding rod 10. The second rotating shaft 5 is mounted on the mounting frame 2 via the sliding rod 10.

[0038] In actual use, multiple rows of support brackets 4 may be installed on the mounting frame 2. If one of the support brackets 4 or the photovoltaic module 20 on it is damaged, the maintenance of it will inevitably affect the power generation of the photovoltaic modules 20 on other rows. In this invention, a guide 7 and a sliding rod 10 are provided on the photovoltaic support. During installation, the sliding end 11 is first slid into the groove 8 from the outlet. Under the action of gravity, the sliding end 11 drives the sliding rod 10 to slide vertically to the bottom of the groove 8. At the same time, the second rotating shaft 5, the first connecting rod 6, the first rotating shaft 3 and the bearing bracket 4 set on the second rotating shaft 5 also slide downward to the use position. When it is necessary to repair or replace a single bearing bracket 4 or photovoltaic module 20, the corresponding sliding rod 10 can be pushed upward a certain distance in the groove 8. The sliding rod 10 will drive the second rotating shaft 5, the first connecting rod 6, the first rotating shaft 3 and the bearing bracket 4 to slide upward to the repair position. Then, the first rotating shaft 3 is rotated to make the bearing bracket 4 move closer to the mounting frame 2. Finally, it is disassembled or repaired on the mounting frame 2. This can avoid affecting the normal power generation of photovoltaic modules 20 on other rows during repair.

[0039] Those skilled in the art can adjust the length of the slide 8 in the vertical direction and the distance by which the sliding rod 10 is pushed upward as needed, as long as the bearing bracket 4 does not collide with the bearing brackets 4 and photovoltaic modules 20 of other rows during the rotation with the first rotating shaft 3.

[0040] Furthermore, such as Figure 6 As shown, in order to facilitate the upward sliding of the sliding rod 10, the photovoltaic bracket also includes: a first magnetic element (not shown in the figure) and a second magnetic element 12. The first magnetic element is disposed on the sliding rod 10; the second magnetic element 12 is disposed on one side of the first magnetic element in a vertical direction, and the magnetic force generated between the second magnetic element 12 and the first magnetic element is used to push the sliding rod 10 to slide in the groove 8.

[0041] The first magnetic component can be a permanent magnet, and the second magnetic component 12 can be configured to generate the same magnetism as the first magnetic component when energized. When a certain support bracket 4 or photovoltaic module 20 needs to be repaired or replaced, the corresponding second magnetic component 12 is first energized to give it the same magnetism as the first magnetic component. This causes the first magnetic component to generate a repulsive force and be pushed upward. As the first magnetic component rises, it also drives the corresponding sliding rod 10, second rotating shaft 5, first connecting rod 6, first rotating shaft 3, and support bracket 4 to rise. As the current increases, the repulsive force increases, and the first magnetic component continues to rise. The slide groove 8 provides guidance for the sliding rod 10, and finally pushes the sliding rod 10 and others upward to the repair position.

[0042] By energizing the second magnetic component 12 to generate magnetism, the sliding rod 10 can be controlled to be pushed only when maintenance is required; in addition, by pushing the sliding rod 10 to slide by magnetic force, high-altitude work can be avoided, making it easier to carry out maintenance later.

[0043] The photovoltaic support also includes a third magnetic component (not shown in the figure) and a fourth magnetic component (not shown in the figure). Both the third and fourth magnetic components can be permanent magnets. The third magnetic component is disposed on the sliding end 11, and the fourth magnetic component is disposed in the sliding groove 8. The third and fourth magnetic components have the same magnetism. The magnetic force generated between the third and fourth magnetic components separates the sliding end 11 from the inner wall of the sliding groove 8 (i.e., the sliding end 11 does not contact the inner wall of the sliding groove 8), thereby reducing the friction between the sliding end 11 and the sliding groove 8, and keeping the sliding end 11 stable in the sliding groove 8, reducing the shaking of the support bracket 4.

[0044] Furthermore, such as Figure 6 and Figure 7 As shown, in order to facilitate the installation of the mounting bracket 4 on the first rotating shaft 3, the linkage assembly further includes: a second link 16, which is disposed on the first rotating shaft 3 and rotates with the first rotating shaft 3; one end of the mounting bracket 4 is disposed on the second link 16 and is disposed on the first rotating shaft 3 through the second link 16.

[0045] Furthermore, such as Figure 6 and Figure 7 As shown, if the bearing bracket 4 is supported only by the first link 6 and the second link 16, a large torque may be generated on the first link 6 and the second link 16, and the bearing bracket 4 may easily sway. Therefore, the link assembly also includes a third link 17, which is disposed on one side of the second link 16 and is used to provide the second link 16 with a supporting force for the bearing bracket 4.

[0046] Since the second link 16 changes position with the rotation of the first rotating shaft 3 and the second rotating shaft 5, the third link 17 can be a telescopic rod. One end of the third link 17 can be set on the second link 16, and the other end can be set on the mounting bracket 2 below the second link 16 to support the bearing bracket 4. The third link 17 and the second link 16, as well as the third link 17 and the mounting bracket 2, can be connected by ball joints.

[0047] In addition, those skilled in the art can use an elastic rope to pull the support bracket 4 in order to reduce the torque on the first link 6 and the second link 16 and the sway of the support bracket 4.

[0048] Furthermore, such as Figure 6 and Figure 7As shown, the linkage assembly also includes a third rotating shaft 18 and a fourth rotating shaft 19. The axis of the third rotating shaft 18 is on the same straight line as the axis of the second rotating shaft 5 and is located on the side of the second rotating shaft 5 away from the mounting bracket 2. The axis of the fourth rotating shaft 19 is on the same straight line as the axis of the first rotating shaft 3.

[0049] To prevent the third link 17 from affecting the rotation of the first rotating shaft 3 and the second rotating shaft 5, the second link 16, the third link 17, and the sliding rod 10 are all provided with mutually perpendicular beginning and end points; the beginning and end points of the first link 6, the second link 16, the third link 17, and the sliding rod 10 are connected in sequence around each other. The end point of the first link 6 is rotatably connected to the beginning point of the second link 16 via the first rotating shaft 3; the end point of the sliding rod 10 is connected to the beginning point of the first link 6 via the second rotating shaft 5. The beginning point of the third link 17 is rotatably connected to the end point of the second link 16 via the third rotating shaft 18, and the end point of the third link 17 is rotatably connected to the beginning point of the sliding rod 10 via the fourth rotating shaft 19. After the first rotating shaft 3 rotates, it drives the third link 17 to rotate around the fourth rotating shaft 19 through the second link 16 and the third rotating shaft 18; after the second rotating shaft 5 rotates, it drives the second link 16 to rotate around the third rotating shaft 18 through the first link 6 and the first rotating shaft 3. The first link 6, the second link 16, the third link 17, and the sliding rod 10 constitute a link assembly.

[0050] Both the third link 17 and the first link 6 are connected to the second link 16, which reduces the torque on the first link 6 and the second link 16, and provides support for the second link 16 in two directions, thereby reducing the sway of the support bracket 4.

[0051] Furthermore, such as Figure 3 As shown, the support bracket 4 includes: a main support beam 13, one end of which is mounted on a second connecting rod 16, and the main support beam 13 is mounted on a first rotating shaft 3 via the second connecting rod 16. Rotation of the first rotating shaft 3 drives the main support beam 13 to rotate via the second connecting rod 16; tension beams 14, two tension beams 14 respectively positioned at both ends of the main support beam 13, forming a space between the two tension beams for installing the photovoltaic module 20; and steel strands 15, which are threaded between the two tension beams 14 to clamp the photovoltaic module 20. When installing the support bracket 4, the main support beam 13 can be first installed on the first rotating shaft 3 using a crane. Then, the first rotating shaft 3 is rotated to bring the main support beam 13 closer to the mounting frame 2. The subsequent tension beams 14, steel strands 15, and photovoltaic modules 20 can then be installed on the mounting frame 2.

[0052] To at least address or improve, to some extent, the existing photovoltaic (PV) support systems' difficulties in resisting extreme weather, high pile foundation costs, and complex construction, this invention also provides a PV power generation system. This PV power generation system includes the PV support system described in any of the above embodiments.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
