Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to an aluminum alloy inclined beam for a flat roof photovoltaic support. Background Technology

[0002] The inclined beams of the photovoltaic (PV) mounting system are installed on a flat roof and can be used to support the pressure blocks of the PV modules. Installing the pressure blocks on the inclined beams of the PV mounting system also serves to limit the movement of the PV modules connected to the pressure blocks.

[0003] The existing photovoltaic support inclined beams can fix the pressure blocks. However, with this type of inclined beam, it is inconvenient to adjust the relative position between the pressure blocks and the inclined beams, and it is also inconvenient to replace the pressure blocks. Utility Model Content

[0004] In view of this, the present invention provides an aluminum alloy inclined beam for a flat roof photovoltaic support to solve the problem of inconvenience in adjusting the position of the pressure block in the prior art.

[0005] This utility model provides an aluminum alloy inclined beam for a flat roof photovoltaic support, suitable for installing photovoltaic module clamps, including:

[0006] There are two support plates, and hinge points are provided at both ends;

[0007] A connecting plate is installed between two support plates;

[0008] The connecting plate forms a groove suitable for installing photovoltaic module clamping blocks, and the groove extends along the length of the support plate.

[0009] In this application, the support plate is the main load-bearing component, ensuring the stability of the inclined beam under load or bending. The photovoltaic bracket inclined beam of this application is made of aluminum alloy and is primarily used in planar photovoltaic bracket systems. The hinge point allows the inclined beam to be articulated in-plane. It has strong energy dissipation performance and facilitates easier adjustment of the photovoltaic module tilt angle. The pressure block can be positioned within a groove, allowing for easy adjustment of the relative position between the pressure block and the inclined beam, and also facilitating the replacement of the pressure block. The groove also limits the movement of the pressure block, preventing it from shifting in the width direction of the support plate.

[0010] In one optional embodiment, the two support plates are arranged in parallel, with the opening of the groove facing the middle of the two support plates. This makes the width direction of the support plates the main bending resistance direction, enhancing the bending strength of the inclined beam. The opening of the groove faces the middle of the two support plates, while the openings of the groove avoid the positions of the two support plates, facilitating the installation of photovoltaic module clamps.

[0011] In one alternative implementation, it further includes:

[0012] A stiffening rib is connected between two support plates and located on one side of the slide groove, with the opening of the slide groove located away from the stiffening rib. This connects the two support plates, enhancing the compressive strength of the inclined beam and preventing deformation of the support plates under pressure. The stiffening rib also shifts the neutral axis of the inclined beam cross-section (the boundary between the compression zone and the tension zone of the cross-section) upwards, thereby improving the load-bearing capacity of the inclined beam.

[0013] In one alternative implementation, it further includes:

[0014] A baffle is connected to one end of the slide groove. It can limit the pressure block along the length of the slide groove, preventing the pressure block from detaching from the slide groove along its length.

[0015] In one alternative implementation, it further includes:

[0016] A latch is provided on the inner wall of the slide groove, and the photovoltaic module pressing block is located between the latch and the bottom of the slide groove. The latch extends along the length direction of the slide groove. This can limit the photovoltaic module pressing block between the latch and the bottom of the slide groove, ensuring that the latch can only move along the length direction of the slide groove, preventing the latch from disengaging from the slide groove in the direction perpendicular to the length of the slide groove, i.e., the width direction of the support plate.

[0017] In one optional embodiment, the hinge point is a hinge hole. Hinges can be provided at both ends of the two support plates, allowing for in-plane hinged connection and connection to a column to form a hinged node.

[0018] In one alternative embodiment, the stiffening ribs are vertically positioned between the two support plates. This enhances the compressive and bending strength of the inclined beam.

[0019] In one alternative embodiment, the opening of the chute is flush with the end of the support plate in the width direction. This prevents interference between the photovoltaic module and the support plate when the photovoltaic module clamping block moves within the chute.

[0020] In one optional embodiment, the latch is positioned at the opening of the slide groove. This increases the movement space of the photovoltaic module pressing block within the slide groove, facilitating its sliding within the groove.

[0021] In one optional embodiment, two latches are provided, respectively on the two side walls of the slide rail. This further ensures that the slide rail will not detach from the support plate in the width direction. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, 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.

[0028] Currently, most photovoltaic (PV) mounting systems use magnesium-aluminum-zinc coated steel. However, the galvanized layer of hot-dip galvanized steel is easily damaged during transportation and installation, leading to reduced corrosion resistance and failure to meet design requirements. Generally, localized corrosion begins to appear on steel mounting systems three to four years after installation. If not addressed promptly, the galvanized layer will quickly deteriorate, gradually corroding the steel itself and posing a significant safety hazard to the stable operation of the PV power station. Furthermore, compared to aluminum alloys, hot-dip galvanized steel is heavier, limiting its application in building-integrated photovoltaic (BIPV) projects. Aluminum alloys, on the other hand, offer moderate strength and price, are lightweight, easy to process and form, abundant in resources, and possess strong corrosion and weather resistance. They require no maintenance during the 25-year operating life of a power station and are highly recyclable, making them a superior alternative to steel for manufacturing solar panel mounting systems in PV power stations.

[0029] Aluminum alloy structures are widely used in photovoltaic support systems due to their light weight and high strength. They also have better corrosion resistance than magnesium-aluminum-zinc coated steel. However, aluminum alloys have poor weldability, which makes the connection of aluminum alloy structures a problem. Especially at the connection nodes, aluminum alloy welding can make the nodes brittle, which poses certain safety hazards to the overall structure.

[0030] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0031] According to the embodiments of this utility model, as shown in the appendix Figure 1 As shown, an aluminum alloy inclined beam for a flat roof photovoltaic bracket is provided, suitable for installing photovoltaic module clamps, comprising:

[0032] There are two support plates 1, each with hinge points at both ends. Each support plate 1 has a length direction, a width direction, and a thickness direction. The length direction is the direction in which the support plate 1 extends. The width and thickness directions are also distinct. The hinge points are located at both ends of the support plate 1 along its length.

[0033] The connecting plate 2 is disposed between the two support plates 1; both ends of the connecting plate 2 can be connected to the ends of the support plates 1 in the width direction respectively.

[0034] The connecting plate 2 forms a groove 3 suitable for installing photovoltaic module clamping blocks, and the groove 3 extends along the length of the support plate 1. The groove 3 can be U-shaped or other shapes. The opening of the groove 3 should not be blocked by the support plate 1, so as to facilitate the installation of photovoltaic module clamping blocks.

[0035] Among them, the inclined beam is made of aluminum alloy. Specifically, the support plate 1, connecting plate 2, stiffening rib 4, buckle 6 and baffle 5 are all made of aluminum alloy.

[0036] In this application, the support plate 1 is the main load-bearing component, ensuring the stability of the inclined beam under load or bending. The photovoltaic bracket inclined beam of this application is made of aluminum alloy and is mainly used in planar photovoltaic bracket systems. The hinge point allows the inclined beam to be hinged in-plane. It has strong energy dissipation performance and facilitates adjustment of the photovoltaic module tilt angle. The pressure block can be set in the slide groove 3, which facilitates adjustment of the relative position between the pressure block and the inclined beam, and also facilitates the replacement of the pressure block. The slide groove 3 can also limit the pressure block, preventing it from moving in the width direction of the support plate 1.

[0037] In one optional embodiment, the two support plates 1 are arranged in parallel, and the opening of the slide groove 3 faces the middle position of the two support plates 1. This makes the width direction of the support plates 1 the main bending resistance direction, enhancing the bending strength of the inclined beam. The opening of the slide groove 3 faces the middle position of the two support plates 1, and the openings of the slide groove 3 avoid the positions of the two support plates 1, which facilitates the installation of photovoltaic module clamps.

[0038] In one alternative implementation, as shown in the appendix Figure 2 As shown, it also includes:

[0039] A stiffening rib 4 is connected between two support plates 1 and located on one side of the sliding groove 3, with the opening of the sliding groove 3 located away from the stiffening rib 4. This connects the two support plates 1, enhancing the compressive strength of the inclined beam and preventing deformation of the support plates 1 under pressure. The stiffening rib 4 also shifts the neutral axis of the inclined beam cross-section (the boundary between the compression zone and the tension zone of the cross-section) upwards, thereby improving the load-bearing capacity of the inclined beam.

[0040] In one alternative implementation, as shown in the appendix Figure 1 As shown, it also includes:

[0041] A baffle 5 is connected to one end of the slide groove 3. It can limit the pressure block along the length of the slide groove 3 to prevent the pressure block from disengaging from the slide groove 3 along the length of the slide groove 3.

[0042] In one alternative implementation, as shown in the appendix Figure 1 As shown, it also includes:

[0043] A latch 6 is disposed on the inner sidewall of the slide groove 3. The photovoltaic module pressing block is located between the latch 6 and the bottom of the slide groove 3, and the latch 6 extends along the length direction of the slide groove 3. This latch 6 can limit the photovoltaic module pressing block between the latch 6 and the bottom of the slide groove 3, ensuring that the latch 6 can only move along the length direction of the slide groove 3, preventing it from disengaging from the slide groove 3 in the direction perpendicular to its length, i.e., the width direction of the support plate 1. The latch 6 can be positioned at the opening of the slide groove 3, increasing the moving space of the pressing block within the slide groove 3 and facilitating adjustment of its relative position within the slide groove 3.

[0044] In one optional embodiment, the hinge point is a hinge hole 7. Hinges 7 can be provided at both ends of the two support plates 1, allowing for in-plane hinged connection and connection to a column to form a hinge node.

[0045] In one alternative embodiment, the stiffening rib 4 is vertically disposed between the two support plates 1. This enhances the compressive and bending strength of the inclined beam.

[0046] In one optional embodiment, the opening of the slide 3 is flush with the end side of the support plate 1 in the width direction. This prevents interference between the photovoltaic module and the support plate 1 when the photovoltaic module pressing block moves within the slide 3.

[0047] In one optional embodiment, the latch 6 is positioned at the opening of the slide groove 3. This increases the movement space of the photovoltaic module pressing block within the slide groove 3, facilitating its sliding within the groove 3.

[0048] In one optional embodiment, there are two latches 6, respectively disposed on the two side walls of the slide groove 3. This further ensures that the slide groove 3 will not detach from the support plate 1 in the width direction.

[0049] This application proposes a novel aluminum alloy cross-section inclined beam, which has excellent bending resistance, facilitates the placement of photovoltaic module clamps, and has a stable structure. The inclined beam is equipped with a baffle 5 at the end, which can effectively prevent the photovoltaic module from shifting laterally. Compared with the conventional solution, which is to arrange limiting rods, it has more economical advantages.

[0050] The groove 3 design proposed in this application is more convenient for the installation and positioning of photovoltaic module clamps compared to C-shaped steel purlins, and the snap-fit ​​6 design can provide sufficient constraints for the photovoltaic module clamps, making the structure stable.

[0051] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
