Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment technology, and specifically to a photovoltaic module support structure that is easy to adjust the angle of. Background Technology

[0002] Fixed photovoltaic (PV) mounting systems are the most common type of residential or small-scale PV power generation systems. One of their core functions is to securely mount PV modules at the optimal tilt angle to maximize solar radiation reception and improve power generation efficiency. Typically, the optimal tilt angle of the PV panels is directly related to the latitude of the installation location, approximating the local latitude, and then slightly optimized based on seasonal power generation needs.

[0003] Currently, most fixed photovoltaic (PV) mounting systems on the market employ discrete angle adjustment schemes. For example, Chinese utility model patent CN203827249U discloses a "self-weight PV mounting system" that uses multiple discrete adjustment holes on the first and second connecting seats. By selecting different hole positions to fix the hooks, the tilt angle of the PV modules can be adjusted. However, because the number and position of the adjustment holes are fixed, the mounting system can only provide a limited number of preset tilt angle options, failing to achieve stepless tilt angle adjustment, resulting in poor adjustment flexibility. This makes it difficult for installers to accurately adjust the PV panels to the theoretically optimal tilt angle calculated from the local latitude, often forcing them to choose the closest hole position, leading to a certain loss in photoelectric conversion efficiency.

[0004] Therefore, a new type of photovoltaic support structure is needed to overcome the shortcomings of imprecise adjustment and achieve more convenient and continuous angle adjustment to meet the precise requirements of different latitude regions for the optimal tilt angle of photovoltaic modules. Utility Model Content

[0005] In order to enable the support structure to flexibly adapt to the different requirements of the tilt angle of the components in different latitude regions, this utility model provides a photovoltaic module support structure that is easy to adjust the angle.

[0006] The technical solution adopted by this utility model is as follows: a photovoltaic module support structure that is easy to adjust the angle includes four sets of mounting seats, which correspond to four mounting positions on both the upper and lower ends of the photovoltaic module. The photovoltaic module is provided with hook support feet at the four mounting positions. The mounting seat is provided with a first mounting hole and a second mounting hole. The hook support feet at the upper and lower ends of the photovoltaic module are connected and fixed to the first mounting hole and the second mounting hole respectively by bolts. At least one of the first mounting hole and the second mounting hole is an adjustment elongated hole.

[0007] Preferably, the first mounting hole is an adjustment elongated hole, and the second mounting hole is a round hole.

[0008] Preferably, the adjusting elongated hole is a straight elongated hole or an arc-shaped hole.

[0009] Preferably, an angle shim is provided in the first mounting hole, the angle shim having the same shape as the first mounting hole and having an angle limiting hole for the bolt to pass through.

[0010] Preferably, the bolt is fitted with a large washer on the outside of the angle washer, and the diameter of the large washer is greater than the width of the angle washer.

[0011] Preferably, the hook support includes an upper hook and a lower support portion. The hook is provided with a first fixing hole for fastening the photovoltaic module, and the support portion is provided with a second fixing hole for fixing to the mounting base.

[0012] Preferably, the material of the hook support leg is rigid plastic.

[0013] Preferably, both the hook and the inner contact surface of the support are provided with anti-slip teeth.

[0014] This utility model has the following beneficial effects: 1. Fine adjustment of tilt angle: The adjustment elongated hole breaks the limitation of the original fixed hole position on the angle selection, allowing installers to make continuous and stepless fine adjustments within the optimal theoretical tilt angle range calculated by local latitude and longitude. This allows the photovoltaic modules to be precisely fixed at the optimal angle with the highest power generation efficiency, maximizing the capture of solar radiation energy and thus improving the overall power generation efficiency of the photovoltaic system. 2. Simple structure: By improving the existing mounting base, the only change is by changing the standard round hole to an elongated hole, resulting in minimal structural changes and making it easy to produce and promote. 3. Adaptability: Adjusting the elongated hole can cover a wide range of angles. By equipping angle shims with different angle limit holes, the same bracket can flexibly adapt to the different requirements of component tilt angle in different latitude regions, enhancing the versatility of the product, reducing the types of bracket models, and lowering production and inventory costs. 4. Stability: By adding angle shims and large washers that match the shape of the adjustment elongated holes, sufficient bearing surface is provided for bolt tightening, ensuring that the photovoltaic modules are stably and reliably fixed, and guaranteeing the wind pressure resistance and durability of the support structure in long-term outdoor environments.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0020] In the embodiments, such as Figures 1-3 As shown, a photovoltaic module support structure for easy angle adjustment includes four sets of mounting bases 1, corresponding to four mounting positions on both the upper and lower ends of the photovoltaic module 2. The photovoltaic module 2 has hook supports 3 at each of the four mounting positions. Each mounting base 1 has a first mounting hole 1.1 and a second mounting hole 1.2. The hook supports 3 at the upper and lower ends of the photovoltaic module 2 are connected and fixed to the first mounting hole 1.1 and the second mounting hole 1.2 respectively by bolts 4. At least one of the first mounting hole 1.1 and the second mounting hole 1.2 is an adjustable elongated hole. This embodiment, by designing at least one mounting hole as an adjustable elongated hole, breaks the limitation of angle selection imposed by traditional discrete hole positions. This allows installers to perform continuous and precise angle installation of the photovoltaic module 2 based on the optimal theoretical tilt angle calculated according to the local latitude. This ensures that the photovoltaic module 2 can be precisely fixed at the optimal angle for highest power generation efficiency, maximizing the capture of solar radiation energy and significantly improving the overall power generation efficiency of the photovoltaic system.

[0021] In the embodiments, such as Figures 1-3 As shown, the first mounting hole 1.1 is an elongated adjustment hole, and the second mounting hole 1.2 is a round hole. This structure forms a rotating axis. During adjustment, the photovoltaic module 2 rotates around the bottom round hole as the axis, and slides along the elongated hole at the top. This structure ensures the stability of the bottom position of the module, making the adjustment process intuitive and controllable, and making installation more convenient and stable.

[0022] In this embodiment, the adjustment hole is either a straight or arc-shaped hole. A straight hole is simple to manufacture and has low cost; the center of an arc-shaped hole coincides with the axis of rotation of the photovoltaic module 2, making the movement trajectory of the hook support 3 smoother and the angle indication more linear during adjustment, thus optimizing the accuracy of adjustment.

[0023] In the embodiments, such as Figure 2As shown, an angle shim 5 is provided inside the first mounting hole 1.1. The angle shim 5 has the same shape as the first mounting hole 1.1 and has an angle limiting hole 5.1 for the bolt 4 to pass through. An angle shim 5 with angle markings or numbers is added, and the angle limiting hole 5.1 on the angle shim 5 provides a precise position for the bolt 4 to pass through. By selecting and equipping angle shims 5 with different angle limiting holes 5.1, the same bracket can flexibly adapt to the different tilt angle requirements of components in different latitude regions, enhancing the versatility of the product, reducing the number of bracket models, and lowering production and inventory costs. This structure eliminates the need for on-site measurement by installers, greatly improving installation convenience.

[0024] In the embodiments, such as Figure 2 As shown, bolt 4 is fitted with a large washer 6 on the outside of angle washer 5. The diameter of the large washer 6 is larger than the width of angle washer 5. This larger diameter ensures that the tightening force of bolt 4 is evenly transmitted to the surfaces of angle washer 5 and mounting base 1 through the large washer 6. This prevents misalignment or detachment of angle washer 5 and overcomes the problem of localized deformation or stripping of bolt 4 due to excessive pressure, thus ensuring the long-term stability of the structure under external forces such as wind loads.

[0025] In the embodiments, such as Figure 3 As shown, the latch support 3 includes an upper latch 3.1 and a lower support 3.2. The latch 3.1 has a first fixing hole 3.3 for fastening the photovoltaic module 2, and the support 3.2 has a second fixing hole 3.4 for fixing to the mounting base 1. The upper latch 3.1 of the latch support 3 securely grips the frame of the photovoltaic module 2 through the first fixing hole 3.3 and screws, while the lower support 3.2 is connected to the mounting base 1 through the second fixing hole 3.4 and bolts 4. This structure has good reliability and simplifies the installation process.

[0026] In this embodiment, the material of the hook support 3 is rigid plastic. Rigid plastic can be glass fiber reinforced nylon, polycarbonate, or acrylonitrile-butadiene-styrene copolymer. It is lightweight, which facilitates the manufacturing and processing of complex-shaped hook support 3. At the same time, its insulation properties enhance the safety of the system, and its certain toughness also helps to protect the frame of the photovoltaic module 2 from scratches or pressure damage during installation.

[0027] In the embodiments, such as Figure 3 As shown, the inner contact surfaces of the hook 3.1 and the support 3.2 are both provided with anti-slip toothed surfaces 3.5. The anti-slip toothed surfaces 3.5 increase the static friction between the photovoltaic module 2 frame and the mounting base 1, preventing accidental slight slippage of the photovoltaic module 2 when subjected to vibration or wind pressure, thus ensuring stability during long-term use.

[0028] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
