Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation technology, and more specifically, to a photovoltaic module installation structure. Background Technology

[0002] As a clean energy source, solar energy is being used more and more widely. One way to utilize solar energy is to collect the sun's light energy using photovoltaic modules (also known as photovoltaic panels or solar panels) and convert it into the electrical energy that people need.

[0003] Currently, the existing technology for installing photovoltaic modules on corrugated steel roofs mostly uses a bracket structure. This bracket typically includes a fixing clamp, a profile guide rail, pads, and pressure blocks. For example, patent documents with publication numbers "CN207819817U" and "CN219834023U" disclose similar bracket structures. The fixing clamp is clamped and fixed to the corrugated steel roof ribs. The profile guide rail is installed on top of the fixing clamp, and the pads are installed on top of the profile guide rail and serve as supports for the photovoltaic modules. The pressure blocks are connected and fixed to the profile and pads with bolts and nuts, pressing the photovoltaic modules firmly. The fixing clamp includes two clamps, the lower ends of which match the shape of the corrugated steel roof ribs. The middle of the two clamps is detachably connected by fasteners. One clamp has a horizontal section at its top for connecting the profile guide rail. However, the horizontal section is biased towards one side of the corrugated steel roof ribs, which can easily lead to uneven stress on both sides of the fixing clamp, resulting in excessive bending moment on one side and deformation of the clamp. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic module installation structure to overcome the aforementioned deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution: A photovoltaic module mounting structure includes a fixing clamp, a profile guide rail, a central pressure block, and a side pressure block. The profile guide rail is connected to the top of the fixing clamp. The central pressure block and the side pressure block are both connected to the profile guide rail. Adjacent photovoltaic modules in the middle are pressed together by the central pressure block, and adjacent photovoltaic modules on the periphery are pressed together by the side pressure blocks. The fixing clamp includes a support member and two clamps. The lower ends of the two clamps match the shape of the corrugated steel sheet. The support member includes a support frame and a connecting plate located at its bottom. The connecting plate is located between the upper ends of the two clamps, and the three are connected by bolts.

[0006] Optionally, the mounting structure also includes a center pad and a side pad connected to the top of the profile guide rail, with the center pad and the center pressure block corresponding one-to-one, and the side pad and the side pressure block corresponding one-to-one.

[0007] Optionally, the central pressure block, the central pad, and the profile guide rail are connected by a first bolt; the side pressure block, the side pad, and the profile guide rail are connected by a second bolt.

[0008] Optionally, the top of the profile guide rail is provided with an upper nut groove along the length direction, and a first square nut is provided in the upper nut groove at the corresponding positions of the first bolt and the second bolt. The first bolt passes through the middle pressure block and the middle pad in sequence and is then tightened with the corresponding first square nut; the second bolt passes through the side pressure block and the side pad in sequence and is then tightened with the corresponding first square nut.

[0009] Optionally, the support frame is connected to the profile guide rail by a third bolt. The bottom of the profile guide rail is provided with a lower nut groove along the length direction. A second square nut is provided at the corresponding position of the third bolt in the lower nut groove. The third bolt passes through the top of the support frame and is tightened with the second square nut.

[0010] Optionally, the top of the middle pad is provided with four right-angle blocks for fitting the corners of the middle photovoltaic module; the top of the side pad is provided with two strip blocks side by side, one of which is used to fit the outer edge of the outer photovoltaic module.

[0011] Optionally, an auxiliary pad is fixedly connected to the top of the side pad, the height of the auxiliary pad being equal to the thickness of the photovoltaic module, and the side pressing block pressing on the top of both the photovoltaic module and the auxiliary pad simultaneously.

[0012] Optionally, the edge pressure block and the middle pressure block have the same structure, both including a U-shaped part and pressure edges provided on both sides of the opening of the U-shaped part.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, a support member is added to the fixing fixture, and the connecting plate of the support member is clamped and fixed between the two clamps. The support frame of the support member supports the profile guide rail. With this setting, on the one hand, the load can be more evenly distributed on the two clamps, avoiding deformation of the clamps due to excessive bending moment on one side; on the other hand, the support frame can increase the distance between the photovoltaic module and the color steel tile while ensuring strength, which is beneficial for ventilation and heat dissipation.

Detailed Implementation

[0015] refer to Figures 1-7 A photovoltaic module installation structure includes a fixing clamp 2, a profile guide rail 3, a central pressure block 4, and a side pressure block 5; the profile guide rail 3 is connected to the top of the fixing clamp 2, adjacent photovoltaic modules 9 in the middle are pressed together by the central pressure block 4, and adjacent photovoltaic modules 9 on the periphery are pressed together by the side pressure block 5, and both the central pressure block 4 and the side pressure block 5 are connected to the profile guide rail 3.

[0016] The fixing clamp 2 includes a support member 202 and two clamps 201. The lower ends of the two clamps 201 match the shape of the protrusions of the corrugated steel sheet 1. Typically, the protrusions of the corrugated steel sheet 1 on which the photovoltaic module 9 is to be installed are diamond-shaped. In this way, after the clamps 201 hold the protrusions, they can prevent them from falling off. After the clamps 201 are locked, the position of the fixing clamp 2 is defined. Further, the support member 202 includes a support frame 2022 and a connecting plate 2021 located at its bottom (it is easy to understand that the support frame 2022 is symmetrical about the connecting plate 2021). The connecting plate 2021 is located between the upper ends of the two clamps 201 and the three are connected by bolts.

[0017] As can be seen, this utility model adds a support member 202 to the fixing clamp 2. The connecting plate 2021 of the support member 202 is clamped and fixed between the two clamps 201, and the support frame 2022 of the support member 202 supports the profile guide rail 3. With this setting, on the one hand, the load can be more evenly distributed on the two clamps 201, avoiding deformation of the clamps 201 due to excessive bending moment on one side. On the other hand, the support frame 2022 can increase the distance between the photovoltaic module 9 and the color steel tile 1 while ensuring strength, which is beneficial for ventilation and heat dissipation. In the prior art, if you want to increase the distance between the photovoltaic module 9 and the color steel tile 1, you can only extend the upper length of the two clamps 201, which can easily weaken the strength of the clamps 201 themselves.

[0018] Based on the above, the installation structure in this embodiment also includes a central pad 6 and a side pad 7 connected to the top of the profile guide rail 3. The central pad 6 corresponds one-to-one with the central pressure block 4, and the side pad 7 corresponds one-to-one with the side pressure block 5. That is, adjacent photovoltaic modules 9 in the middle are supported by the central pad 6 and pressed tightly by the central pressure block 4, while the outer photovoltaic modules 9 are supported by the side pad 7 and pressed tightly by the side pressure block 5. It is worth noting that this arrangement avoids the photovoltaic modules 9 being directly installed on the profile guide rail 3, with the profile guide rail 3 only acting as a support. This helps to reduce the size of the profile guide rail 3 and facilitates cost reduction.

[0019] In this embodiment, the central pressure block 4, the central pad 6, and the profile guide rail 3, as well as the side pressure block 5, the side pad 7, and the profile guide rail 3, are all connected by bolts. Specifically, the central pressure block 4, the central pad 6, and the profile guide rail 3 are connected by a first bolt 10; the side pressure block 5, the side pad 7, and the profile guide rail 3 are connected by a second bolt 11. Further, the top of the profile guide rail 3 is provided with an upper nut groove 301 along its length. A first square nut 13 is provided in the upper nut groove 301 at the corresponding positions of the first bolt 10 and the second bolt 11. The first bolt 10 passes through the central pressure block 4 and the central pad 6 in sequence and is then tightened with the corresponding first square nut 13; the second bolt 11 passes through the side pressure block 5 and the side pad 7 in sequence and is then tightened with the corresponding first square nut 13.

[0020] The support frame 2022 and the profile guide rail 3 are also connected by bolts. Specifically, the support frame 2022 and the profile guide rail 3 are connected by a third bolt 12. The bottom of the profile guide rail 3 is provided with a lower nut groove 302 along the length direction. The lower nut groove 302 is provided with a second square nut 14 at the corresponding position of the third bolt 12. After the third bolt 12 passes through the top of the support frame 2022, it is tightened with the second square nut 14.

[0021] It is worth noting that using square nuts in the upper nut groove 301 and lower nut groove 302 of the profile guide rail 3 to connect with the corresponding bolts can prevent the nuts from rotating and facilitate quick installation. Furthermore, under the above concept, it should be understood that using square-head bolts and ordinary round nuts should belong to the same concept and should also fall within the protection scope of this utility model. In this method, the head of the square-head bolt is set in the upper nut groove 301 and lower nut groove 302 of the upper profile guide rail 3.

[0022] refer to Figure 8 In this embodiment, the top of the middle pad 6 is provided with four right-angled blocks 601, which are used to fit the corners of the middle photovoltaic module 9, facilitating the rapid positioning of the photovoltaic module 9 and also serving as a limiting function. (Reference) Figure 9 Furthermore, two strip-shaped blocks 701 are arranged side by side on the top of the side pad 7. One of the strip-shaped blocks 701 is used to fit the outer edge of the outer photovoltaic module 9, thereby limiting the outward displacement of the outer photovoltaic module 9.

[0023] refer to Figure 2 , Figure 4 , Figure 5 , Figure 10 and Figure 11 In this embodiment, an auxiliary pad 8 is fixedly connected to the top of the side pad 7. Preferably, the fixed connection is a bolt connection. Specifically, a countersunk hole is provided on the top of the auxiliary pad 8 to accommodate the head of the bolt. After the bolt passes through the side pad 7, it is locked with a nut. The height of the auxiliary pad 8 is equal to the thickness of the photovoltaic module 9. The side pressure block 5 presses on the top of both the photovoltaic module 9 and the auxiliary pad 8. This arrangement allows for the selection of an auxiliary pad 8 of appropriate thickness according to the thickness of the photovoltaic module 9, facilitating the installation of photovoltaic modules 9 of different thicknesses. Furthermore, the side pressure block 5 and the middle pressure block 4 can be shared, meaning that the side pressure block 5 and the middle pressure block 4 have the same structure. Specifically, both include a U-shaped portion 401 and pressure edges 402 provided on both sides of the opening of the U-shaped portion 401.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
