[0002] Photovoltaic power generation is widely used in various fields, among which the application ratio in building energy conservation is increasing year by year. Photovoltaic sun sheds, as a new type of building structure integrating power generation, sunshade and aesthetics, are becoming more and more popular in the market. During the installation of photovoltaic sun sheds, photovoltaic modules are generally installed on the mounting brackets (such as purlins and beams) on the roof of the building.

[0003] The existing photovoltaic module fixing technology generally uses a pressing block, the upper end of which presses the photovoltaic module frame, and the lower end of which is connected to the purlin by bolts. Reference can be made to a photovoltaic array collapse prevention pressing block disclosed in publication number CN110677103A; the photovoltaic module frame is placed on the photovoltaic module rail, and the pressing plate is located on the top surface of the photovoltaic module frame. The fixing bolts pass through the bolt holes and the photovoltaic module rail in sequence and are tightly connected and fixed, so that the first pressing foot and the second pressing foot are firmly fixed on the photovoltaic module rail, and the photovoltaic module frame is pressed and fixed by the pressing plate to prevent the photovoltaic array from moving and flipping. However, this method requires fastening from the front of the photovoltaic module during installation. During construction, the construction personnel need to be on top of the photovoltaic module to perform the fastening operation, and it is inevitable to step on the photovoltaic module, which is easy to cause hidden cracks and ruptures of the photovoltaic module. In addition, in the later maintenance and disassembly of the components, it is necessary to return to the photovoltaic module to perform the disassembly operation, which is difficult and has a high risk factor. Summary of the invention

[0004] In view of this, the present application proposes a photovoltaic module installation structure with a grounding function, which adopts a fixing method of pressing under the photovoltaic panel and does not require workers to work on top of the module.

[0005] According to one aspect of the present application, a photovoltaic assembly installation structure with a grounding function is provided, comprising: a first pressing plate, a second pressing plate and a U-shaped bolt;

[0006] The photovoltaic panel mounting frame is suitable for clamping the photovoltaic panel, and the mounting plate of the photovoltaic panel mounting frame is suitable for being placed on the purlin; the mounting plate and the purlin are located between the first pressing plate and the second pressing plate, and the two ends of the U-shaped bolt pass through the first pressing plate, the purlin and the second pressing plate in sequence, and are suitable for pressing the mounting plate between the first pressing plate and the purlin;

[0007] A locking groove is formed on the top surface of the first pressing plate, and the locking groove matches the closed end of the U-shaped bolt, and the closed end of the U-shaped bolt can be embedded in the locking groove;

[0008] One side of the first pressing plate contacting the mounting plate is provided with more than two conductive piercing portions.

[0009] In a possible implementation, the first pressing plate includes: a pressing plate and a supporting plate; the pressing plate is arranged on one side of the supporting plate, the pressing plate contacts the mounting plate, and the supporting plate contacts the purlin;

[0010] The locking groove is arranged on the supporting plate, and more than two conductive piercing parts are arranged on the side where the pressing plate contacts the mounting plate.

[0011] In a possible implementation, the cross-section of the support plate is a "Π"-shaped structure.

[0012] In a possible implementation, the conductive piercing portion includes: a round hole and two or more sharp spikes;

[0013] The circular hole is formed on the pressing plate, and two or more sharp spikes are arranged in sequence along the circumferential direction of the circular hole; the tips of the sharp spikes face the mounting plate.

[0014] In a possible implementation manner, two conductive piercing portions are provided.

[0015] In a possible implementation, the main body of the second pressing plate is a rectangular plate-shaped structure.

[0016] In a possible implementation, the device further includes: a rain collector;

[0017] The rain collector is arranged between the photovoltaic panel installation frame and the purlin, and the opening of the rain collector faces the photovoltaic panel installation frame.

[0018] Beneficial effects: This application is easy and quick to install, and the grounding method has a simple structure, which reduces the safety hazards caused by poor equipotential connection. It achieves safe and stable installation of photovoltaic sun shed components, simplifies the installation process, and improves work efficiency. The traditional upper pressure fixing method requires workers to go above the components to work, which poses a safety risk. However, this application adopts a fixing method of pressing the bottom of the photovoltaic panel, which does not require workers to work above the photovoltaic panel. While avoiding risks, it ensures the stable installation of the photovoltaic components, and the entire installation process is safe and efficient.

[0032] Figure 5 The front view of the U-shaped bolt of the embodiment of the present application is shown. Figure 1 As shown, the photovoltaic component installation structure with grounding function includes: a photovoltaic panel installation frame 100 suitable for being placed on a purlin 600; a mounting plate 130 of the photovoltaic panel installation frame 100 and the purlin 600 are located between a first pressing plate 200 and a second pressing plate 300, and two ends of a U-shaped bolt 400 pass through the first pressing plate 200, the purlin 600 and the second pressing plate 300 in sequence, and are suitable for pressing the mounting plate 130 between the first pressing plate 200 and the purlin 600; a locking groove 212 is provided on the top surface of the first pressing plate 200, and the locking groove 212 matches the closed end of the U-shaped bolt 400, and the closed end of the U-shaped bolt 400 can be embedded in the locking groove 212; and one side of the first pressing plate 200 contacting the mounting plate 130 is provided with more than two conductive piercing portions.

[0033] Here, it should be noted that the photovoltaic assembly includes a photovoltaic panel mounting frame 100 and a photovoltaic panel 500; the photovoltaic panel mounting frame 100 is suitable for clamping the photovoltaic panel 500 and fixing the photovoltaic panel 500 on the purlin 600, wherein the mounting plate 130 of the photovoltaic panel mounting frame 100 is placed on the upper surface of the purlin 600, the first pressing plate 200 is pressed on the top of the mounting plate 130, and the second pressing plate 300 is pressed on the bottom of the purlin 600, and the U-shaped bolt 400 fixes and locks the first pressing plate 200, the mounting plate 130, the purlin 600 and the second pressing plate 300, and the locking groove 212 on the first pressing plate 200 It is suitable for improving the stability of the U-bolt 400 after installation. The conductive piercing part directly contacts the mounting plate 130 to achieve a reliable conductive connection and a strong grounding effect. The overall installation process of the present application is to first install the first pressing plate 200 and the U-bolt 400 at the specified position of the purlin 600, and then place the photovoltaic module as a whole at the position to be installed on the purlin 600. After that, the first pressing plate 200 is operated below the photovoltaic module to hold the mounting plate 130 of the photovoltaic panel mounting frame 100, and finally the second pressing plate 300 is installed below the purlin 600 and the nut 410 is tightened on the U-bolt 400. The present application is simple and fast to install, and the grounding method has a simple structure, which reduces the safety hazards caused by poor equipotential connection. It realizes the safe and stable installation of photovoltaic modules, simplifies the installation process, and improves work efficiency. The traditional upper pressure fixing method requires staff to go above the module to work, which poses a safety risk. The present application adopts a fixing method of pressing the photovoltaic panel 500 from below, which does not require workers to work on top of the components. This avoids risks while ensuring the stable installation of the photovoltaic components, making the entire installation process safe and efficient.

[0034] In a possible implementation, the first pressing plate 200 includes: a pressing plate 220 and a supporting plate 210; the pressing plate 220 is arranged on one side of the supporting plate 210, the pressing plate 220 contacts the mounting plate 130, and the supporting plate 210 contacts the purlin 600; a locking groove 212 is provided on the supporting plate 210, and two or more conductive piercing portions are arranged on the side of the pressing plate 220 contacting the mounting plate 130. The pressing plate 220 and the supporting plate 210 are integrally formed, such as Figure 2 As shown, the support plate 210 is a strip-shaped structure, and its cross section is a "Π"-shaped structure, the open side of the "Π"-shaped structure is buckled on the purlin 600, and the clamping plate 220 on one side of the support plate 210 covers the mounting plate 130. It should be noted that the support plate 210 is set at a certain height to increase the clamping force of the clamping plate 220 on the mounting plate 130, so as to prevent the support plate 210 from tilting up and causing a gap between the clamping plate 220 and the mounting plate 130.

[0035] In one possible implementation, the support plate 210 is provided with two bolt holes 211, and the two bolt holes 211 are suitable for inserting the U-shaped bolt 400; the locking groove 212 is opened between the two bolt holes 211, and when the U-shaped bolt 400 completely passes through the two bolt holes, the closed end of the U-shaped bolt 400 is embedded in the locking groove 212 to ensure that the U-shaped bolt 400 does not slide or deviate during the tightening process.

[0036] In a possible implementation, the conductive piercing portion includes: a circular hole 221 and two or more spikes 222; the circular hole 221 is provided on the pressing plate 220, and the two or more spikes 222 are arranged in sequence along the circumferential direction of the circular hole 221; the tip of the spike 222 faces the mounting plate 130. Here, it should be noted that in order to achieve equipotential connection between the photovoltaic panels 500 and between the photovoltaic panels 500 and the photovoltaic panel mounting frame 100, the traditional method requires a separate puncture gasket, which increases the complexity and cost of the installation. However, the present application directly sets a spike 222 structure under the pressing plate 220. When the photovoltaic panel 500 is installed, these raised spikes 222 will pierce the oxide film of the photovoltaic panel mounting frame 100, thereby ensuring that a good conductive connection is formed between the photovoltaic panel mounting frame 100 and the purlin 600, thereby realizing the grounding function. Through this design, not only the installation steps are simplified, but also the work efficiency is improved, and the safety hazards caused by poor equipotential connection are reduced.

[0037] Further, such as Figure 3 As shown, there are ten spikes 222 , and the ten spikes 222 are evenly arranged around the circular hole 221 .

[0038] In a possible implementation, two conductive piercing portions are provided. Figure 3 As shown, the main body of the pressing plate 220 is a rectangular plate-shaped structure, and the two conductive piercing portions on the pressing plate 220 have the same structure and are arranged along the body length direction of the pressing plate 220.

[0039] In a possible implementation, the main body of the second pressing plate 300 is a rectangular plate-shaped structure. As shown in the figure, the second pressing plate 300 is provided with two bolt holes 310, and the two bolt holes 310 are suitable for inserting two ends of the U-shaped bolt 400.

[0040] In one possible implementation, the U-shaped bolt 400 is provided with two matching nuts 410, the two nuts 410 are sleeved on the two screws of the U-shaped bolt 400, and are arranged close to the second pressure plate 300. Under the locking action of the U-shaped bolt 400 and the two nuts 410, the first pressure plate 200 and the second pressure plate 300 tightly clamp the middle mounting plate 130 and the purlin 600.

[0041] In a possible implementation, the photovoltaic panel mounting frame 100 includes: a support portion 120 , a clamping portion 110 and a mounting plate 130 ; the support portion 120 is disposed between the clamping portion 110 and the mounting plate 130 . Figure 1 A cross-sectional view of a photovoltaic panel mounting frame 100 is shown. Figure 1 As shown, the clamping part 110 is a strip-shaped structure with a "C"-shaped cross-section, the photovoltaic panel 500 is suitable for inserting into the inner side of the opening of the clamping part 110, and the mounting plate 130 is a rectangular plate-shaped structure; the support part 120, the mounting plate 130, and the clamping part 110 are integrally formed. The photovoltaic panel mounting frame 100 is a photovoltaic module self-contained device, which is a prior art and will not be described in detail here.

[0042] In a possible implementation, it further includes: a rain collector 700; the rain collector 700 is arranged between the photovoltaic panel mounting frame 100 and the purlin 600, and the opening of the rain collector 700 faces the photovoltaic panel mounting frame 100. Here, it should be noted that the rain collector 700 is suitable for drainage and preventing rainwater from penetrating into the system. Further, the main body of the rain collector 700 is a strip structure with a "U"-shaped cross-section, and the open end of the rain collector 700 faces the photovoltaic panel 500. Since there are inevitably gaps between each photovoltaic panel 500 after the overall structure is installed, in order to prevent rainwater from flowing into the purlin 600 through the gap and causing the purlin 600 to rust, a rain collector 700 is set at the bottom of the mounting plate 130 of each two adjacent photovoltaic panel mounting frames 100. The rain collector 700 is tightly held between the mounting plate 130 and the purlin 600 by the first pressing plate 200, the second pressing plate 300, and the U-shaped bolt 400, so as to collect rainwater between the two photovoltaic panel mounting frames 100 and prevent rainwater from directly contacting the purlin 600.

[0043] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
