Description

Technical Field

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

[0002] With increasing global environmental awareness and the continued growth in demand for clean energy, the photovoltaic industry is entering a period of rapid development. Bifacial photovoltaic modules, with their ability to generate electricity using both the light-receiving and back-shielding sides, significantly improve the utilization rate of photovoltaic power generation sites, becoming an important direction for technological innovation in the industry. However, traditional photovoltaic mounting systems have revealed many problems limiting the performance of ultra-high bifaciality modules when adapted to them.

[0003] In related technologies, such as Figure 1 The vertical mounting bracket photovoltaic structure shown in this scheme requires an independent mounting slot for each photovoltaic module, which significantly increases the amount of material used and production costs. At the same time, the photovoltaic modules need to be inserted into the mounting slots from top to bottom during installation, which is difficult and inconvenient to operate.

[0004] like Figure 2 The vertically mounted solar photovoltaic panels shown can achieve vertical installation of photovoltaic modules, but they suffer from complex structure and high energy consumption. Their design relies on external force or electric drive, increasing system operating costs. Furthermore, the back of the bracket has partial shading, severely affecting the light reception of the back side of the bifacial photovoltaic modules, leading to a reduction in overall power generation efficiency.

[0005] Based on this, a novel photovoltaic bracket and photovoltaic system have been developed in this utility model to solve the above problems. Utility Model Content

[0006] The first objective of this utility model is to provide a photovoltaic support bracket, the installation space of which can simultaneously accommodate photovoltaic modules of different specifications, the number and type of photovoltaic modules can be freely adjusted, and the spacing of the pressure blocks can be adjusted to adapt to changes in the width of the photovoltaic modules; at the same time, only the first and second columns on both sides are needed to support multiple photovoltaic modules, reducing material usage and manufacturing costs.

[0007] This utility model adopts the following technical solution: a photovoltaic support bracket, comprising:

[0008] The first column extends vertically;

[0009] The second column is parallel to the first column and forms an installation space between the first column and the second column to accommodate multiple photovoltaic modules.

[0010] The first limiting member has one end connected to the bottom of the first column and the other end connected to the bottom of the second column; and the first limiting member is provided with a support part for supporting the lower edge frame of the photovoltaic module, the support part extending in the horizontal direction.

[0011] Multiple pressure blocks are spaced apart along the horizontal extension direction of the support portion. The pressure blocks are used to fix the photovoltaic module to the first limiting member.

[0012] Furthermore, the photovoltaic support also includes a second limiting member, which is disposed opposite to the first limiting member. The second limiting member is used to abut against the frame of the upper edge of the photovoltaic module, and both ends of the second limiting member are respectively connected to the top of the first column and the second column.

[0013] Furthermore, the second limiting member is provided with a limiting guide groove, the opening of which faces the first limiting member.

[0014] Furthermore, the second limiting component includes a first limiting baffle and a second limiting baffle located on both sides of the limiting guide groove. The first limiting baffle is used to limit the light-receiving side of the photovoltaic module, and the second limiting baffle is used to limit the back-light side of the photovoltaic module. The height of the first limiting baffle in the vertical direction is less than the height of the second limiting baffle.

[0015] Furthermore, the bottom of both the first and second columns has multiple sets of corresponding positioning grooves spaced vertically at intervals.

[0016] The two ends of the first limiting member are selectively inserted into a set of limiting grooves of the first column and the second column.

[0017] Furthermore, the cross-sectional shape of the limiting groove is one of H-shaped, L-shaped, U-shaped or T-shaped;

[0018] The cross-sectional shape of the first limiting component is adapted to the cross-sectional shape of the limiting groove.

[0019] Furthermore, the cross-sectional shape of the first limiting member is one of T-shaped, H-shaped, U-shaped, L-shaped, or type I.

[0020] Furthermore, both the first column and the second column are provided with a U-shaped receiving cavity, with the U-shaped receiving cavity of the first column and the U-shaped receiving cavity of the second column being arranged opposite to each other.

[0021] Furthermore, multiple sets of mounting holes are provided at vertical intervals between the first and second columns;

[0022] And / or, both the bottom of the first column and the second column are provided with flange support feet, and the flange support feet are fixedly connected to the first column and the second column.

[0023] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0024] In this utility model, the photovoltaic bracket is first arranged vertically with the first and second columns spaced parallel to each other, ensuring the spacing between the columns is suitable for the width of multiple photovoltaic modules. Then, the two ends of the second limiting member are connected to the bottom of the columns, and the support portion extends horizontally. Next, the photovoltaic modules are lifted to a certain height and placed in the installation space between the first and second columns, so that the lower edge of the photovoltaic modules is supported and lifted by the support portion of the first limiting member. Combined with the locking action of the pressure block, this ensures that the photovoltaic modules are not at risk of loosening.

[0025] In this invention, the first column, second column, and first limiting member of the photovoltaic bracket only obstruct the edges of the photovoltaic modules, avoiding the obstruction of the back surface of the photovoltaic modules by traditional brackets, thus improving the bifaciality and enhancing the power generation efficiency of the photovoltaic panels. An installation space is formed between the first and second columns, which can simultaneously accommodate photovoltaic modules of different specifications. The number and type of photovoltaic modules can be freely adjusted, and the spacing of the clamps can be adjusted to adapt to changes in the width of the photovoltaic modules. Furthermore, the vertical arrangement of the first and second columns ensures that the photovoltaic modules are installed vertically. On one hand, the gravity of rainwater along the vertical surface of the photovoltaic modules accelerates the scouring effect, quickly removing dust, bird droppings, and other attachments, improving scouring efficiency compared to inclined surfaces. On the other hand, the vertical installation of the photovoltaic modules increases the probability that dust, bird droppings, and other debris will naturally slide off under gravity, effectively avoiding the accumulation problem of attachments in traditional inclined or horizontal installation methods.

[0026] Meanwhile, only the first and second pillars on both sides are needed to support multiple photovoltaic modules, reducing material usage and manufacturing costs. Furthermore, during installation, the photovoltaic modules only need to be raised to the height of the support structure, eliminating the need to lift them very high, thus simplifying installation.

[0027] Furthermore, the support and the pressure block form a double constraint, effectively preventing the photovoltaic modules from sliding horizontally or tipping over due to wind or vibration. When a single photovoltaic module is damaged, it can be replaced simply by removing the corresponding pressure block, without dismantling the entire support structure.

[0028] The second objective of this utility model is to provide a photovoltaic system, which includes the aforementioned photovoltaic bracket and at least one set of photovoltaic modules disposed within the installation space of the photovoltaic bracket. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] The following is in conjunction with the appendix Figure 3 To be continued Figure 8 The present invention will be described in detail with specific embodiments:

[0041] like Figures 3 to 8 As shown, this utility model provides a photovoltaic support bracket, which includes a first column 1, a second column 2, a first limiting member 3, and multiple pressure blocks 4.

[0042] The first column 1 extends vertically, and the second column 2 is parallel to the first column 1, forming an installation space between the first column 1 and the second column 2 to accommodate multiple sets of photovoltaic modules 5.

[0043] One end of the first limiting member 3 is connected to the bottom of the first column 1, and the other end is connected to the bottom of the second column 2; and the first limiting member 3 is provided with a support part 30 for supporting the lower edge frame of the photovoltaic module 5, the support part 30 extending horizontally to provide support for the lower edge of the photovoltaic module 5.

[0044] Multiple pressure blocks 4 are spaced apart along the horizontal extension direction of the support portion 30. The pressure blocks 4 are used to fix the photovoltaic module 5 to the first limiting member 3. Specifically, the pressure blocks 4 can be fixed to the first limiting member 3 by means of bolts, welding or riveting, and form a limiting constraint on the lower edge frame of the photovoltaic module 5, thereby fixing the photovoltaic module and preventing the photovoltaic module 5 from sliding horizontally.

[0045] In this utility model, the photovoltaic bracket is first arranged vertically with the first column 1 and the second column 2 spaced parallel to each other, ensuring that the distance between the two columns is suitable for the width of multiple photovoltaic modules 5. Then, the two ends of the second limiting member 6 are connected to the bottom of the first column 1 and the second column 2 respectively, and the support part 30 extends horizontally. Next, the photovoltaic module 5 is lifted to a certain height and placed in the installation space between the first column 1 and the second column 2, so that the lower edge frame of the photovoltaic module 5 is supported and lifted by the support part 30 of the first limiting member 3. Combined with the locking effect of the pressure block 4, it is ensured that there is no risk of the photovoltaic module 5 loosening.

[0046] In this invention, the first column 1, second column 2, and first limiting member 3 of the vertical mounting bracket structure only obstruct the edges of the photovoltaic module 5, avoiding the obstruction of the back surface of the photovoltaic module by traditional brackets, thus improving the bifaciality and enhancing the power generation efficiency of the photovoltaic panel. An installation space is formed between the first column 1 and the second column 2, which can simultaneously accommodate photovoltaic modules 5 of different specifications. The number and type of photovoltaic modules 5 can be freely adjusted, and the spacing of the pressure blocks 4 can be adjusted to adapt to changes in the width of the photovoltaic module 5. Furthermore, the vertical arrangement of the first column 1 and the second column 2 ensures that the photovoltaic module 5 is installed vertically. On the one hand, the gravity of rainwater along the vertical surface of the photovoltaic module 5 accelerates the scouring effect, quickly removing dust, bird droppings, and other attachments, improving scouring efficiency compared to inclined surfaces. On the other hand, the vertical installation of the photovoltaic module 5 increases the probability that dust, bird droppings, and other debris will naturally slide off under gravity, effectively avoiding the problem of attachment accumulation in traditional inclined or horizontal installation methods.

[0047] Meanwhile, only the first column 1 and the second column 2 on both sides are needed to support multiple sets of photovoltaic modules 5, reducing material usage and manufacturing costs. Furthermore, during installation, the photovoltaic modules 5 only need to be raised to the height of the support section 30mm, eliminating the need to raise them very high, thus saving effort during installation.

[0048] Furthermore, the support 30 and the pressure block 4 form a double constraint, effectively preventing the photovoltaic module 5 from sliding horizontally or tipping over due to wind or vibration. When a single photovoltaic module 5 is damaged, it can be replaced simply by removing the corresponding pressure block 4, without dismantling the entire support structure.

[0049] Furthermore, in some specific embodiments, such as Figure 1 , 7 As shown, the photovoltaic support also includes a second limiting member 6, which abuts against the upper edge frame of the photovoltaic module 5, forming a limiting constraint on the upper edge frame of the photovoltaic module 5. Simultaneously, both ends of the second limiting member 6 are fixedly connected to the tops of the first column 1 and the second column 2, respectively. This rectangular support area for the photovoltaic module 5, formed by the second limiting member 6, the first limiting member 3, and the first and second columns 1 and 2 on both sides of the installation space, constructs a stable mechanical structure that can effectively resist external loads such as strong winds and snow accumulation, providing good support stability.

[0050] It should be noted that the second limiting member 6 can be fixedly connected to the tops of the first and second columns 1 and 2 on both sides in various ways. For example, it can be directly locked and fixed using bolts, screws, or other locking devices, or it can be fixedly connected by snap-fit ​​or welding. However, preferably, the second limiting member 6 is fixedly connected to the tops of the first and second columns 1 and 2 on both sides using bolts or other locking devices. This fixing method is simple and reliable, and facilitates subsequent installation, disassembly, and maintenance.

[0051] Specifically, the second limiting member 6 is provided with a limiting guide groove 60, the opening of which faces the first limiting member 3. During installation, the limiting guide groove 60 of the second limiting member 6 is fastened and installed at the upper edge frame of the photovoltaic module 5, so that the upper edge frame of the photovoltaic module 5 is embedded in the limiting guide groove 60, forming a wrapping limiting constraint on the upper edge frame of the photovoltaic module 5, thereby enhancing the installation stability of the photovoltaic module 5. In this embodiment, the limiting guide groove 60 is a U-shaped limiting guide groove.

[0052] More specifically, the second limiting member 6 includes a first limiting baffle 61 and a second limiting baffle 62 located on both sides of the limiting guide groove 60. The first limiting baffle 61 is disposed on the light-receiving side of the photovoltaic module 5, forming a limiting constraint on the light-receiving side of the photovoltaic module 5; the second limiting baffle 62 is disposed on the back side of the photovoltaic module 5, forming a limiting constraint on the back side of the photovoltaic module 5, and the height of the first limiting baffle 61 in the vertical direction is less than the height of the second limiting baffle 62, forming a design similar to short in the front and long in the back, reducing the shading of the light-receiving side of the photovoltaic module 5.

[0053] Furthermore, in some specific embodiments, such as Figure 1 , 4 As shown in Figure 6, the bottom of both the first column 1 and the second column 2 has multiple sets of corresponding limiting grooves 10 at intervals along the vertical direction. In other words, the bottom of the first column 1 has multiple first limiting grooves, and the bottom of the second column 2 has multiple second limiting grooves that correspond to the first limiting grooves. The corresponding first limiting grooves and second limiting grooves constitute a set of limiting grooves 10 mentioned above.

[0054] The two ends of the first limiting member 3 are selectively inserted into a set of limiting grooves 10 of the first column 1 and the second column 2, thereby adjusting the vertical installation position of the photovoltaic module 5. Since the vertical installation position of the first limiting member 3 is adjustable, this vertical mounting bracket structure can be adapted to the installation requirements of photovoltaic modules 5 at different heights.

[0055] Specifically, the cross-sectional shape of the limiting groove 10 is adapted to the cross-sectional shape of the first limiting member 3. During installation, after inserting the end of the first limiting member 3 into the corresponding limiting groove 10, it can also be fixedly connected to the first column 1 and the second column 2 by bolts, screws and other locking parts. The installation method is simple, reliable and can further enhance the connection strength.

[0056] It should be noted that the cross-sectional shape of the limiting groove 10 can be H-shaped, T-shaped, L-shaped, U-shaped, etc.; correspondingly, the cross-sectional shape of the first limiting member 3 can be T-shaped, H-shaped, U-shaped, L-shaped, I-shaped, etc. It should be noted that the T-shaped includes both vertically arranged T-shaped and horizontally arranged T-shaped (i.e., ┝-shaped) formed by rotating a T-shaped member 90°. Furthermore, the cross-sectional shape of the limiting groove 10 and the cross-sectional shape of the first limiting member 3 can be compatible; they can be the same shape, or the end of the first limiting member 3 can be directly inserted into the limiting groove 10. For example, a T-shaped first limiting member 3 can be inserted into an H-shaped limiting groove 10, or an I-shaped first limiting member 3 can be inserted into a T-shaped limiting groove 10, etc.

[0057] Preferably, the cross-sectional shape of the limiting groove 10 is H-shaped, L-shaped, or U-shaped, and the cross-sectional shape of the first limiting member 3 is a horizontal L-shape or a T-shape rotated 90°. Correspondingly, a limiting part 31 is formed on the side of the first limiting member 3 near the back surface of the photovoltaic module, forming a limiting constraint on the photovoltaic module 5 and further enhancing the connection stability; at the same time, it does not constrain the light-receiving surface of the photovoltaic module 5, facilitating the installation of the photovoltaic module 5. In addition, the first limiting member 3 can better cooperate with the pressure block 4 to clamp the photovoltaic module, and the pressure block 4 is directly pressed onto the frame of the photovoltaic module 5. In this embodiment, as Figure 4 As shown, the cross-sectional shape of the limiting groove 10 is H-shaped; the cross-sectional shape of the first limiting member 3 is T-shaped rotated 90°, and the size of the limiting groove 10 is larger than the outer diameter of the first limiting member 3, which facilitates the installation of the first limiting member 3 in the limiting groove 10.

[0058] Furthermore, in some specific embodiments, the first column 1 and the second column 2 can take many forms, such as square columns, prisms, I-shaped columns, U-shaped columns, Z-shaped columns, etc., and no specific limitation is made in this utility model.

[0059] Preferably, both the first column 1 and the second column 2 are provided with a U-shaped receiving cavity, with the U-shaped receiving cavities of the first column 1 and the second column 2 arranged opposite to each other, meaning that the openings of the U-shaped receiving cavities both face the photovoltaic module 5. During installation, the two side edges of the photovoltaic module 5 are embedded into the U-shaped receiving cavities, enhancing the connection stability between the photovoltaic module 5 and the first column 1 and the second column 2. Simultaneously, multiple sets of mounting holes 11 can be provided at intervals in the vertical direction of the first column 1 and the second column 2. The mounting holes 11 can be used to fix the first limiting member 3, the second limiting member 6, and the side edge frames of the photovoltaic module 5. In this embodiment, both the first column 1 and the second column 2 are U-shaped columns, and the mounting holes 11 penetrate the two side walls of the U-shaped receiving cavities.

[0060] Furthermore, in some specific embodiments, such as Figure 5 As shown, both the first column 1 and the second column 2 are equipped with flanged support feet 7 at their bottoms. The flanged support feet 7 are fixedly connected to the bottom of the column 1. By setting the flanged support feet 7, the contact area between the column and the foundation is increased, thereby reducing the foundation stress. In this invention, the specific shape and size of the flanged support feet 7 are not specifically limited, as long as they are larger than the bottom size of the column. Anchor bolt holes can also be provided on the flanged support feet 7 for fixed connection between the flanged support feet 7 and the foundation. Alternatively, the fixed connection between the column and the foundation can be achieved by pouring cement columns at the bottom of the first column 1 and the second column 2.

[0061] Furthermore, there are various ways to fix the flange support foot 7 to the bottom of the column, such as welding, bolt connection, snap-fit ​​connection, etc. In this embodiment, the two are welded together, which is a simple and highly stable connection method.

[0062] Meanwhile, an L-shaped connecting plate 8 can be provided at the bottom of the first column 1 and the second column 2. One side of the L-shaped connecting plate 8 is locked and fixed to the first column 1 and the second column 2 with bolts, etc., and the other side is fixedly connected to the flange support foot 7, further enhancing the connection strength between the column and the flange support foot 7.

[0063] It should be noted that the first column 1, the second column 2, the second limiting member 6, the first limiting member 3, and the L-shaped connecting plate 8 in this utility model are preferably made of carbon steel and their surfaces are hot-dip galvanized. Carbon steel is relatively inexpensive, which saves production costs. At the same time, hot-dip galvanizing can prevent it from rusting for 30 years when used outdoors, thus extending its service life.

[0064] Based on the aforementioned photovoltaic bracket, this utility model also provides a photovoltaic system, which includes the aforementioned photovoltaic bracket and at least one set of photovoltaic modules 5 disposed within the installation space of the photovoltaic bracket. Specifically, as shown... Figure 8 As shown, the photovoltaic system includes multiple photovoltaic brackets arranged side by side. The photovoltaic system provided by this utility model includes all the technical solutions of all the above-described embodiments of the photovoltaic brackets, and therefore has at least all the beneficial effects brought about by the technical solutions of the above-described embodiments of the photovoltaic brackets, which will not be described in detail here.

[0065] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
