Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a bracket and a photovoltaic system using the bracket. Background Technology

[0002] The application of solar energy to generate electricity through photovoltaic modules is becoming increasingly widespread. Photovoltaic modules consist of photovoltaic panels and brackets used to support them. In related technologies, most brackets have a fixed and non-adjustable angle during installation, making it difficult to adapt to installations in different regions. Utility Model Content

[0003] The main objective of this application is to propose a bracket and photovoltaic system that aims to improve the problem of traditional brackets being unadjustable.

[0004] To achieve the above objectives, the bracket proposed in this application includes a base and a column. The base extends along a first preset direction to support one end of the photovoltaic panel assembly. One end of the column is connected to the base, and the other end of the column extends along a second preset direction to support the other end of the photovoltaic panel assembly. The second preset direction is set at an angle to the first preset direction. The column includes N first counterweights stacked along the second preset direction, where N is greater than or equal to 1. And / or, the base includes M counterweights arranged along the first preset direction, where M is greater than or equal to 1. The counterweights are provided with limiting slots and limiting protrusions on opposite sides along the first preset direction and / or on opposite sides along the second preset direction, respectively, and the limiting slots and limiting protrusions are adapted to each other.

[0005] In one embodiment, the limiting slot includes a first limiting slot, and the limiting protrusion includes a first limiting protrusion. The first limiting slot and the first limiting protrusion are respectively disposed on opposite sides of the counterweight in the first preset direction, and the first limiting protrusion is adapted to the first limiting slot.

[0006] In one embodiment, the first limiting card protrusion includes a first protrusion and a second protrusion. The first protrusion protrudes from the counterweight, and the second protrusion is connected to the side of the first protrusion away from the counterweight. The size of the second protrusion in the second preset direction is greater than the size of the first protrusion in the second preset direction.

[0007] In one embodiment, the first limiting slot penetrates the surface of the counterweight in a third preset direction, wherein both the first preset direction and the second preset direction are set at an angle to the third preset direction.

[0008] In one embodiment, the first limiting slot includes:

[0009] An insertion port, wherein the size of the insertion port in the second preset direction is smaller than the size of the second protrusion in the second preset direction, and the size of the insertion port in the third preset direction is greater than or equal to the size of the second protrusion in the third preset direction; wherein the first preset direction and the second preset direction are both set at an angle to the third preset direction; and

[0010] A rotational clearance space is provided, which is connected to the insertion port, and the second protrusion is installed in the rotational clearance space and can rotate within the rotational clearance space.

[0011] In one embodiment, the insertion port has a first stop wall and a second stop wall disposed opposite to each other in the third preset direction, for limiting the opposite sides of the first protrusion in the third preset direction.

[0012] In one embodiment, the limiting slot includes a second limiting slot, and the limiting protrusion includes a second limiting protrusion. The second limiting slot and the second limiting protrusion are respectively disposed on opposite sides of the counterweight in the second preset direction, and the second limiting protrusion can be engaged into the second limiting slot.

[0013] In one embodiment, the top of the counterweight is provided with a mounting groove, and the bracket also includes a fastener and an adapter. One end of the fastener is inserted into the mounting groove, and the other end extends out of the mounting groove and is connected to the adapter.

[0014] In one embodiment, the support further includes a connecting member, wherein at least two of the counterweights are threaded through the connecting member in the first preset direction and / or the second preset direction to connect the at least two counterweights in series.

[0015] And / or, at least one of the counterweight blocks of the column and the base is provided with a fixing part; the bracket also includes a connector, which is fixedly connected to the fixing part.

[0016] This application also proposes a photovoltaic system, including a photovoltaic panel assembly and the aforementioned support frame, wherein one end of the photovoltaic panel assembly is mounted on the top of the column and the other end is connected to the base.

[0017] The technical solution of this application, by setting a base and a column, with the base extending along a first preset direction and one end of the column connected to the base and the other end extending in a second preset direction, allows the base and column to support the opposite ends of the photovoltaic panel module, thereby achieving a stable support effect for the photovoltaic panel module. Furthermore, by including N counterweights stacked along the second preset direction in the column, users can stack any number of counterweights to change the height of the column, thus changing the support angle for the photovoltaic panel module and improving the problem of traditional non-adjustable brackets. By including at least one counterweight extending along the first preset direction in the base, users can arrange any number of counterweights in the first preset direction to change the length of the base, thereby also changing the support angle for the photovoltaic panel module and improving the problem of traditional non-adjustable brackets. Additionally, by changing the number of counterweights arranged in the first and / or second preset directions, it is possible to accommodate photovoltaic panel modules of different sizes. In addition, by providing limiting slots and limiting protrusions on opposite sides of the counterweight along the first preset direction and / or on opposite sides of the second preset direction, and by matching the limiting protrusions with the limiting slots, the effect of connecting and limiting adjacent counterweights to each other is achieved, thereby improving the stability of the base.

[0045] The application of solar energy to generate electricity through photovoltaic (PV) modules is becoming increasingly widespread. A PV module consists of a photovoltaic panel and a support frame. Understandably, PV modules are typically installed at a certain angle to the horizontal plane to more effectively utilize solar energy for power generation. However, the angle and duration of sunlight exposure vary across different regions, so it's better to adopt different installation angles for different areas when installing PV modules. The support frame is used to support the PV modules, so an adjustable frame is needed to adjust the installation angle. However, in related technologies, most support frames have a fixed, non-adjustable angle during installation, making it difficult to adapt to installations in different regions.

[0046] To address the issue of non-adjustable stents, this application proposes a stent.

[0047] Please refer to the reference. Figures 1 to 7 In one embodiment of this application, the bracket includes a base 100 and a column 200. The base 100 extends along a first preset direction to support one end of the photovoltaic panel assembly 300. One end of the column 200 is connected to the base 100, and the other end of the column 200 extends along a second preset direction to support the other end of the photovoltaic panel assembly 300. The second preset direction is set at an angle to the first preset direction. The column 200 includes N counterweights 110 stacked along the second preset direction, where N is greater than or equal to 1. And / or, the base 100 includes M counterweights 110 arranged along the first preset direction, where M is greater than or equal to 1. The counterweights 110 are provided with limiting slots 110A and limiting protrusions 110B on opposite sides along the first preset direction and / or on opposite sides along the second preset direction, respectively. The limiting slots 110A and limiting protrusions 110B are adapted to each other.

[0048] When supporting the photovoltaic panel module 300, the base 100 can serve as a component supporting one end of the photovoltaic panel module 300. In this application, the base 100 extends along a first preset direction, for example, the first preset direction can be a horizontal direction or a direction forming an acute or obtuse angle with the horizontal direction. The support also includes a column 200, one end of which is connected to the base 100, and the other end extends along a second preset direction, so that the top end of the column 200 can be used to support the other end of the photovoltaic panel module 300. By having the top end of the column 200 and the base 100 jointly support the photovoltaic panel module 300, the photovoltaic panel module 300, after installation, has a state that forms a certain angle with the horizontal plane. Specifically, when the other end of the column 200 extends along the second preset direction, the second preset direction can be set perpendicular to the first preset direction, or it can be set at an acute or obtuse angle with the first preset direction.

[0049] When the support column 200 includes N counterweights 110 stacked along a second preset direction, where N is greater than or equal to 1, N can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. The number of counterweights 110 is related to the thickness of the counterweights 110 and the installation angle of the photovoltaic panel module 300. That is, the support column 200 may include only one counterweight 110, or it may include at least two counterweights 110 stacked along the second preset direction. It is understandable that when the column 200 includes different numbers of counterweights 110, the height of the column 200 will also be different, and thus the support height of the column 200 supporting the other end of the photovoltaic panel module 300 will also be different, resulting in different tilt angles of the photovoltaic panel module 300 relative to the horizontal plane after installation. Therefore, in this application, the height of the column 200 is changed by changing the number of counterweights 110 stacked, thereby achieving the effect of changing the support angle of the bracket on the photovoltaic panel module 300, so that the bracket in this application can adapt to the different installation angle requirements of the photovoltaic panel module 300 in different regions.

[0050] The base 100 includes M counterweights 110 arranged along a first preset direction, where M is greater than or equal to 1. When at least one counterweight 110 is connected to at least one other counterweight 110, M can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. Users can select any number of counterweights 110 according to actual needs, thereby changing the length of the base 100 along the first preset direction. Similarly, by adjusting the number of counterweights 110 in the base 100, the support angle of the photovoltaic panel module 300 can be changed. Furthermore, this arrangement can accommodate photovoltaic panel modules 300 of different sizes. The placement direction of the counterweights 110 in the column 200 can be the same as or different from the placement direction of the counterweights 110 in the base 100. For example, when the counterweight 110 is rectangular, the counterweight 110 in the base 100 can be positioned such that its length extends along a first preset direction, while the counterweight 110 in the column 200 can be positioned such that its length extends along the first preset direction or its length extends along a second preset direction. When at least one counterweight 110 in the column 200 is connected to at least one counterweight 110 in the base 100, the connection can be achieved by using an external connecting component, or by setting a mutually engaging or plugging structure on the counterweight 110 and the counterweight 110 to achieve the mutual connection effect.

[0051] Specifically, the counterweight 110 can be a cement counterweight, but without considering cost, it can also be a metal counterweight. The counterweight 110 can be rectangular, circular, polygonal, or other irregular shapes. When the counterweight 110 is rectangular, its length can extend along a second preset direction, or its length can extend horizontally. At least two counterweights 110 are provided, and these two counterweights 110 can be stacked along the second preset direction; or at least two counterweights 110 can be stacked in a stepped manner, i.e., they can be stacked in a staggered manner to form a stepped shape. To ensure stability after at least two counterweights 110 are stacked, the support may further include a connecting component that connects the at least two counterweights 110; or, a first connecting portion and a second connecting portion may be provided on opposite sides of the counterweights 110, with the first connecting portion of one of two adjacent counterweights 110 connected to the second connecting portion of the other, thereby achieving a good connection effect between the two adjacent counterweights 110 and reducing the risk of tipping over after the counterweights 110 are stacked. When the counterweights 110 are cylindrical or regular polygonal, when the counterweights 110 are stacked in the second preset direction, in order to maintain a good support effect, their thickness direction can be arranged along the second preset direction. When the counterweights 110 are stacked in the first preset direction, their circular or regular polygonal surfaces can be oriented towards the second preset direction. In addition, when the column 200 is connected to the base 100, the column 200 can be connected to the top of the base 100 or to the side wall of the base 100. When the column 200 is connected to the top of the base 100, it can also be connected using a connecting component, such as an L-shaped connecting piece threaded together. Alternatively, the column 200 and the top of the base 100 can be connected by snap-fit ​​or plug-in. When the column 200 is connected to the side wall of the base 100, it can also be connected using a connecting component, or by snap-fit ​​or plug-in.

[0052] In this application, by providing limiting slots 110A and limiting protrusions 110B on opposite sides along a first preset direction and / or on opposite sides along a second preset direction, and by ensuring that the limiting protrusions 112 and limiting slots 111 are compatible, when at least two counterweights 110 are provided in the column 200 or base 100, the limiting protrusion 110B of one of two adjacent counterweights 110 can be engaged into the limiting slot 110A of the other, thereby achieving the effect of mutual connection and mutual limiting between adjacent counterweights 110, thus improving the stability of the base 100. Specifically, the limiting protrusions 110B can be cylindrical, prismatic, T-shaped, dovetail-shaped, etc., and the limiting slots 110A only need to be compatible with the limiting protrusions 110B.

[0053] The technical solution of this application, by setting a base 100 and a column 200, with the base 100 extending along a first preset direction and one end of the column 200 connected to the base 100 and the other end extending in a second preset direction, allows the base 100 and column 200 to support the opposite ends of the photovoltaic panel module 300, thereby achieving a stable support effect for the photovoltaic panel module 300. Furthermore, by including N counterweights 110 stacked along the second preset direction in the column 200, users can stack any number of counterweights 110 to change the height of the column 200, thereby changing the support angle for the photovoltaic panel module 300 and improving the problem of traditional non-adjustable supports. By including at least one counterweight extending along the first preset direction in the base 100, users can arrange any number of counterweights 110 in the first preset direction to change the length of the base 100, thereby also changing the support angle for the photovoltaic panel module 300 and improving the problem of traditional non-adjustable supports. Furthermore, by changing the number of counterweights 110 arranged in the first preset direction and / or the second preset direction, it is possible to accommodate photovoltaic panel modules 300 of different sizes. Additionally, by providing limiting slots 110A and limiting protrusions 110B on opposite sides of the counterweights 110 along the first preset direction and / or on opposite sides of the second preset direction, and by ensuring that the limiting protrusions 112 and limiting slots 111 are compatible, the effect of interconnecting and mutually limiting adjacent counterweights 110 is achieved, thereby improving the stability of the base 100.

[0054] Please refer to the reference. Figures 1 to 6 Furthermore, the limiting slot 110A includes a first limiting slot 111, and the limiting protrusion 110B includes a first limiting protrusion 112; the first limiting slot 111 and the first limiting protrusion 112 are respectively disposed on opposite sides of the counterweight 110 in a first preset direction, and the first limiting protrusion 112 is adapted to the first limiting slot 111.

[0055] By providing a first limiting slot 111 and a first limiting protrusion 112 on opposite sides of the counterweight 110 along the first preset direction, and by adapting the first limiting protrusion 112 to the first limiting slot 111, when there are at least two counterweights 110 arranged in the first preset direction, the first limiting protrusion 112 of one of the two adjacent counterweights 110 can be inserted into the first limiting slot 111 of the other, thereby achieving the effect of connecting the two adjacent counterweights 110 to each other in the first preset direction, thus improving the stability of the base 100.

[0056] Please refer to the reference. Figures 2 to 5In some other embodiments of this application, the first limiting protrusion 112 includes a first protrusion 1121 and a second protrusion 1122. The first protrusion 1121 protrudes from the counterweight 110, and the second protrusion 1122 is connected to the side of the first protrusion 1121 away from the counterweight 110. The size of the second protrusion 1122 in the second preset direction is larger than the size of the first protrusion 1121 in the second preset direction.

[0057] This configuration ensures that once the first limiting protrusion 112 is inserted into the first limiting slot 111, it is difficult for the first limiting protrusion 112 to come out along the first preset direction, thereby improving the connection strength of the two adjacent counterweights 110 in the first preset direction.

[0058] Specifically, the first protrusion 1121 of the first limiting protrusion 112 can be a column, a cube, a cuboid, etc., and the second protrusion 1122 can be a cuboid, a hemisphere, or other shapes. That is, the first protrusion 1121 and the second protrusion 1122 of the first limiting protrusion 112 can together form a dovetail shape, a T-shape, or other shapes. The goal is to ensure that after the counterweight 110 is installed, the dimension of the second protrusion 1122 in the second preset direction is greater than the dimension of the first protrusion 1121 in the second preset direction. The first limiting protrusion 112 can be a dovetail protrusion, a T-shaped protrusion, or an L-shaped protrusion, etc.

[0059] Please refer to the reference. Figures 1 to 6 Based on the scheme that the counterweight 110 is provided with a first limiting slot 111 and a first limiting protrusion 112 on opposite sides in the first preset direction, in some embodiments of this application, the first limiting slot 111 penetrates the surface of the counterweight 110 in the third preset direction, wherein the first preset direction and the second preset direction are both set at an angle to the third preset direction.

[0060] Specifically, the first limiting protrusion 112 can be a dovetail-shaped protrusion, a T-shaped protrusion, or an L-shaped protrusion, etc., and the cross-sectional shape of the first limiting groove 111 is adapted to the cross-sectional shape of the first limiting protrusion 112. By having the first limiting groove 111 penetrate the surface of the counterweight 110 in the third preset direction, it is convenient to insert the first limiting protrusion 112 into the first limiting groove 111 along the third preset direction, thereby facilitating the mutual assembly of the first limiting groove 111 and the first limiting protrusion 112.

[0061] Please refer to the reference. Figures 3 to 6The first limiting slot 111 includes an insertion port 1111 and a rotation clearance space 1112. The size of the insertion port 1111 in the second preset direction is smaller than the size of the second protrusion 1122 in the second preset direction, and the size of the insertion port 1111 in the third preset direction is greater than or equal to the size of the second protrusion 1122 in the second preset direction. The first preset direction and the second preset direction are both set at an angle to the third preset direction. The rotation clearance space 1112 is connected to the insertion port 1111, and the second protrusion 1122 is installed in the rotation clearance space 1112 and can rotate in the rotation clearance space 1112.

[0062] By making the size of the insertion port 1111 of the first limiting slot 111 in the second preset direction smaller than the size of the second protrusion 1122 in the second preset direction, and by making the second protrusion 1122 able to be installed in the rotation clearance space 1112 communicating with the insertion port 1111, the second protrusion 1122 can be located in the rotation clearance space 1112, and the second protrusion 1122 can be stopped by the insertion port 1111, thereby reducing the risk of the second protrusion 1122 coming out of the insertion port 1111.

[0063] Furthermore, by making the size of the insertion port 1111 in the third preset direction greater than or equal to the size of the second protrusion 1122 in the second preset direction, the second protrusion 1122 can rotate within the rotation clearance space 1112. This makes it convenient for the user to assemble two counterweights 110 with the same placement direction together. One of the counterweights 110 can be rotated 90° first, so that the second protrusion 1122 and the first protrusion 1121 of the first limiting protrusion 112 of the counterweight 110 can be aligned with the insertion port 1111 and inserted into the rotation clearance space 1112 through the insertion port 1111. After the second protrusion 1122 enters the rotation clearance space 1112, the counterweight 110 is rotated in the opposite direction to the initial position. At this time, the second protrusion 1122 can be limited by the insertion port 1111, thereby reducing the risk of the first limiting protrusion 112 coming off from the insertion port 1111. It is understood that the structure of the first limiting slot 111 and the first limiting protrusion 112 in this embodiment makes the assembly process of the two include rotation, insertion, and then reverse rotation. This setting reduces the possibility of the user sliding the first limiting protrusion 112 along the opening direction of the vertical insertion port 1111, and instead allows the first limiting protrusion 112 to be directly aligned with the insertion port 1111 and inserted into the insertion port 1111, thereby facilitating user operation and ensuring that the first limiting slot 111 and the first limiting protrusion 112 have a good limiting engagement effect.

[0064] Specifically, the insertion port 1111 can penetrate the surfaces of the counterweight 110 on both sides of the counterweight 110 along the third preset direction, or it can not penetrate the surfaces of the counterweight 110 on both sides of the counterweight 110 along the third preset direction.

[0065] Please refer to the reference. Figure 3 and Figure 6 Furthermore, the insertion port 1111 has a first stop wall 111a and a second stop wall 111b disposed opposite to each other in a third preset direction, for limiting the opposite sides of the first protrusion 1121 in the third preset direction.

[0066] This configuration allows the first stop wall 111a and the second stop wall 111b to limit the opposite sides of the first protrusion 1121 in the third preset direction, thereby enabling the two adjacent counterweights 110 to be in phase with each other in the third preset direction after assembly. This reduces the need for separate limiting components to limit the counterweights 110, for example, the aforementioned connecting component 120 can be omitted.

[0067] Please refer to the reference. Figures 1 to 6 In some embodiments of this application, the limiting slot 110A includes a second limiting slot 115, and the limiting protrusion 110B includes a second limiting protrusion 113. The second limiting slot 115 and the second limiting protrusion 113 are respectively disposed on opposite sides of the counterweight 110 in a second preset direction, and the second limiting protrusion 113 can be inserted into the second limiting slot 115.

[0068] By providing a second limiting protrusion 113 and a second limiting groove 115 in the second preset direction, and by having the second limiting protrusion 113 able to engage with the second limiting groove 115, the two counterweights 110 stacked in the second preset direction can also limit each other, thereby reducing the risk of the counterweights 110 slipping off the counterweights 110.

[0069] Specifically, in one example, the second limiting groove 115 extends through both opposite sides of the counterweight 110 in a third preset direction, wherein the first and second preset directions are both set at an angle to the third preset direction. This arrangement facilitates the sliding of the second limiting protrusion 113 into the second limiting groove 115 along the third preset direction. Alternatively, in another example, the sidewall of the second limiting groove 115 can be a cylindrical body, such as a round or rectangular cylinder. This arrangement ensures that the second limiting protrusion 113, once positioned within the second limiting groove 115, can be stopped by the sidewall of the second limiting groove 115 in any horizontal direction, thereby further improving the stability of the counterweight 110 mounted on the counterweight 110.

[0070] Please refer to the reference. Figures 7 to 12 In some embodiments of this application, the top of the counterweight 110 is provided with a mounting groove 116, and the bracket also includes a fastener 400 and an adapter 500. One end of the fastener 400 is inserted into the mounting groove 116, and the other end extends out of the mounting groove 116 and is connected to the adapter 500.

[0071] Specifically, in order to achieve the effect that one end of the fastener 400 can be inserted into the mounting slot 116, in one example, please refer to the reference. Figures 7 to 10 The longitudinal cross-sectional shape of the mounting groove 116 can be an inverted T-shaped groove. In this case, the opening of the mounting groove 116 is stepped from the bottom to the top of the column 200, and the opening area at the bottom of the mounting groove 116 is larger than the opening area at the top of the mounting groove 116. The corresponding fastener 400 can be a bolt with a nut or other T-shaped snap-fit ​​component that can fit into the mounting groove 116. This allows the fastener 400 to be limited in the vertical direction by the mounting groove 116 after being installed in it, thereby ensuring the stability of the adapter 500 connected to the fastener 400. Alternatively, in another example, please refer to the reference... Figure 11 and Figure 12 The mounting groove 116 can be an inverted trapezoidal groove. In this case, the opening of the mounting groove 116 gradually decreases from the bottom to the top of the column 200. The corresponding fastener 400 can be a bolt with a nut or other snap-fit ​​component that can be inserted into the inverted trapezoidal groove. This allows the fastener 400 to be limited in the vertical direction by the mounting groove 116 after it is installed in the mounting groove 116, thereby ensuring the stability of the adapter 500 connected to the fastener 400.

[0072] To facilitate the installation of the fastener 400 into the mounting groove 116, the mounting groove 116 can penetrate through the side wall of the counterweight 110, thereby allowing the fastener 400 to slide from the side wall of the counterweight 110 into the mounting groove 116. In addition, when the longitudinal cross-sectional shape of the mounting groove 116 is an inverted T-shaped groove, and the fastener 400 is also T-shaped, that is, the fastener 400 may include a base 410 adapted to the bottom opening of the mounting groove 116 and a fastening part 420 connected to the base 410. The fastening part 420 is at least partially inside the top opening of the mounting groove 116. In this case, the fastener 400 can be rotated 90° around the vertical axis so that the base 410 of the fastener 400 can be inserted through the top of the mounting groove 116. After it is inserted into the bottom of the mounting groove 116, it is rotated in the opposite direction to the initial angle. At this time, the base 410 is inserted into the opening at the bottom of the mounting groove 116 and is stopped in the vertical direction by the inner wall of the opening at the top of the mounting groove 116, thereby achieving the effect of fastener 400 being engaged with the mounting groove 116.

[0073] In this embodiment, the fastener 400 can connect the counterweight 110 to the adapter 500, and then connect it to the photovoltaic panel assembly 300 through the adapter 500.

[0074] like Figure 1As shown, the support further includes a connector 120, through which at least two counterweights 110 are inserted in a first preset direction and / or a second preset direction to connect the at least two counterweights 110 in series.

[0075] Specifically, the connector 120 can be a rope or a connecting rod, etc.

[0076] By threading at least two counterweights 110 through the connector 120 along a first preset direction and / or a second preset direction, the effect of connecting at least two counterweights 110 in series is achieved. In addition, this arrangement further reduces the risk of at least two counterweights 110 sliding off each other in a direction that forms an angle with the connector 120 and thus disengaging from each other.

[0077] Please refer to the reference. Figure 7 and Figure 8 In some embodiments of this application, at least one of the column 200 and the base 100 has a fixing part 117 on the counterweight 110; the bracket also includes a connector 700, which is fixedly connected to the fixing part 117.

[0078] Specifically, at least one counterweight 110 of the column 200 is provided with a fixing part 117, so that the connector 700 fixes the counterweight 110 on the column 200. Alternatively, at least one counterweight 110 of the base 100 is provided with a fixing part 117, so that the connector 700 fixes the counterweight 110 on the base 100. Or, at least one counterweight 110 of the column 200 is provided with a fixing part 117, and at least one counterweight 110 of the base 100 is provided with a fixing part 117, so that the fixing parts 117 on at least one counterweight 110 of the base 100 and at least one counterweight 110 of the column 200 are respectively connected by the two ends of the connector 700, so as to achieve the effect of fixing the column 200 and the base 100.

[0079] The fixing part 117 can be a fixing bolt, bolt hole, fastener, or snap hole, etc. The connecting part can be a connecting plate, connecting rod, connecting support frame, etc., as long as the connecting part can be connected to the fixing part 117.

[0080] This application also proposes a photovoltaic system; please refer to the relevant references. Figure 1 , Figure 3 as well as Figure 7The photovoltaic system includes a photovoltaic panel assembly 300 and a support frame. The specific structure of the support frame is as described in the above embodiments. Since this photovoltaic system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. One end of the photovoltaic panel assembly 300 is installed on the top of the column 200, and the other end is connected to the base 100.

[0081] By installing one end of the photovoltaic panel module 300 on the top of the column 200 and connecting the other end to the base 100, the photovoltaic panel module 300 is installed at an angle relative to the horizontal plane, thereby making more efficient use of solar energy for power generation.

[0082] Specifically, an adapter 500 can be installed at the top of the column 200. The adapter 500 serves as an intermediate connection between the photovoltaic panel module 300 and the counterweight block 110. The adapter 500 can be connected to the counterweight block 110 via fasteners 400, welding, or other methods. Furthermore, a pressure block 600 can be connected to the adapter 500 to press the photovoltaic panel module 300 firmly onto the adapter 500, thereby reducing the risk of the photovoltaic panel module 300 slipping.
