Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and particularly relates to the installation technology of photovoltaic modules.

Background Art

[0002] With the increasing size of photovoltaic modules, due to material, structural and technological limitations, the cost reduction space of existing aluminum alloy frames is relatively small. At present, steel frames and composite material frames have emerged in the market as cost reduction solutions. Since the materials of such frames are quite different from those of aluminum alloy frames, it has a certain impact on the traditional installation methods of photovoltaic modules. The pressing plate installation structure adopted in the prior art realizes the fixation of the photovoltaic module by pressing and fixing the C side of the module frame. Since the pressing plate is fixed by pressing plate bolts, mainly a downward pressure is applied to the C side of the module frame, and there is no limit in the horizontal direction. Under strong wind or other horizontal external forces, horizontal misalignment and up-and-down loosening are likely to occur between the pressing plate and the C side of the part frame.

Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a pressing plate installation structure for photovoltaic modules with enhanced limiting, so as to solve the problems of easy horizontal misalignment and up-and-down loosening between the pressing plate and the C side of the part frame in the prior art.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] A pressing plate installation structure for photovoltaic modules with enhanced limiting includes a back pressing plate pressed on the C side of the photovoltaic module frame. A bent edge is provided at the edge of the C side. Pressing feet and supporting feet are respectively provided on the opposite sides of the back pressing plate. The pressing feet are pressed on the C side, and the pressing feet are provided with locks that cooperate with the bent edge.

[0006] Preferably, the bent edge is an L-shaped structure, and the lock is provided with a lock groove for locking the bent edge.

[0007] Preferably, the back pressing plate is further provided with a connecting part connecting the pressing feet and the supporting feet. A high position section is provided in the middle of the connecting part. A first strengthening section connected to the pressing feet is provided on the first side of the high position section, and a second strengthening section connected to the supporting feet is provided on the second side.

[0008] Preferably, the bottom surfaces of the pressing feet and the first strengthening section both extend horizontally, and the bottom surface of the first strengthening section is higher than the bottom surface of the pressing feet. A convex edge extending downward below the bottom surface of the first strengthening section is provided at the bottom of the pressing feet, and the convex edge and the bottom surface of the first strengthening section cooperate to form a lock groove.

[0009] Preferably, the first strengthening section and / or the pressing feet are provided with longitudinally penetrating hollow cavities; and / or, a top groove is formed between the first strengthening section and the second strengthening section and the high position section.

[0010] Preferably, the top surface of the pressing foot and the first reinforcing section extends obliquely upward to the high-position section to form an integral slope; and / or, the bottom surface of the pressing foot is provided with an anti-slip concave-convex surface.

[0011] Preferably, the top surface of the second reinforcing section is provided with a reinforcing groove; and / or, the second reinforcing section is arc-transitionally connected to both the high-position section and the supporting foot.

[0012] Preferably, the back pressing plate is made of stainless steel or aluminum alloy profile; and / or, the bottom surfaces of the C side and the supporting foot are flush.

[0013] Preferably, the upper part of the B side of the frame is provided with a bending structure for clamping the photovoltaic panel in cooperation with the A side.

[0014] Preferably, the frame is made of stainless steel or composite material.

[0015] The utility model adopts the above technical solutions and has the following beneficial effects:

[0016] 1. Pressing feet and supporting feet are respectively arranged on the opposite sides of the back pressing plate. The supporting feet support on the purlin to provide stable support for the back pressing plate, and the pressing feet press on the C side, so that the photovoltaic module is tightly fixed on the purlin through the back pressing plate.

[0017] Since the pressing foot is provided with a lock for cooperating with the bending edge, after the pressing foot and the C side are locked and fixed, it has the functions of horizontal limit and up-down limit. Cooperating with the conventional bolt fixation, the pressing on the C side of the component frame is more reliable. When the power station encounters extreme weather, the component frame may slide. At this time, the back pressing plate can lock the component frame to prevent it from coming off, solving the problems of easy horizontal misalignment and up-down looseness between the pressing plate and the C side of the component frame in the prior art.

[0018] 2. The bending edge is of an L-shaped structure and is formed by steel closing. The lock is provided with a lock groove for locking the bending edge, that is, by horizontally sliding the pressing foot, the bending edge is buckled and fixed with the lock groove, which is convenient for installing the back pressing plate.

[0019] 3. The connecting part connects the pressing foot and the supporting foot, and can connect fasteners such as bolts to fix the back pressing plate. The first reinforcing section and the second reinforcing section are used to increase the overall structural strength of the back pressing plate.

[0020] 4. The convex edge and the bottom surface of the first reinforcing section cooperate to form a lock groove, and the bottom surface of the first reinforcing section can also play a role in limiting the bending edge.

[0021] 5. The design of the hollow cavities on the first reinforcing section and the pressing foot, as well as the design of the top groove, can not only save materials and reduce costs, but also have the effect of increasing strength.

[0022] 6. The design of the pressing foot and the overall slope on the first strengthening section can save materials, while the anti-slip concave-convex surface is used to increase friction, making the back pressure plate not easy to slide.

[0023] 7. The top surface of the second strengthening section is provided with strengthening grooves, which can not only save materials and reduce costs, but also have the effect of increasing strength.

[0024] 8. The back pressure plate is made of stainless steel or aluminum alloy profiles, which not only prevents rust and extends the service life, but also has the advantage of low mass production cost.

[0025] The bottom surface of the C side is flush with the supporting feet, so as to ensure that when the pressing foot presses on the C side, the supporting feet are stably supported on the purlin.

[0026] 9. The upper part of the B side of the frame is provided with a bending structure for clamping the photovoltaic panel in cooperation with the A side, which also has the effect of increasing the overall structural strength of the frame.

[0027] 10. The frame is made of stainless steel or composite materials, which can further reduce costs compared with aluminum alloy frames.

[0040] Referring to the prior art, several photovoltaic modules are distributed in a rectangular array and installed on a photovoltaic bracket. A plurality of photovoltaic modules are arranged side by side both horizontally and vertically. The photovoltaic modules are provided with frames, and the photovoltaic bracket is provided with a plurality of purlins. The purlins are fixedly connected with a pressing plate assembly to fix the frames of the photovoltaic modules.

[0041] Refer to Figures 1 to 4As shown, the frame 100 has side A 101, side B 102, and side C 103. A bent edge 104 is provided at the edge of side C 103. The frame 100 is made of stainless steel or composite material, which can reduce costs compared to an aluminum alloy frame. In this embodiment, a mounting structure for a photovoltaic module pressing plate with enhanced limiting function is designed for the frame with the above structure, which includes a back pressing plate 1 pressed on side C of the photovoltaic module frame. Pressing feet 11 and supporting feet 12 are respectively provided on opposite sides of the back pressing plate 1. The pressing feet 11 are pressed on side C 103, and the pressing feet 11 are provided with latches that cooperate with the bent edge.

[0042] In the above technical solution, the supporting feet support on the purlin to provide stable support for the back pressing plate, and the pressing feet are pressed on side C, so that the photovoltaic module is tightly fixed on the purlin through the back pressing plate. Since the pressing feet are provided with latches that cooperate with the bent edge, after the pressing feet are locked and fixed with side C, they have horizontal limiting and up-and-down limiting functions. Combined with conventional bolt fixing, the pressing of side C of the module frame is more reliable. When the power station encounters extreme weather, the module frame may slide. At this time, the back pressing plate can lock the module frame to prevent it from coming off, solving the problems of easy horizontal misalignment and up-and-down looseness between the pressing plate and side C of the module frame in the prior art.

[0043] Wherein, the bottom surfaces of side C 103 and the supporting feet 12 are flush to ensure that while the pressing feet are pressed on side C, the supporting feet support on the purlin.

[0044] Specifically, the bent edge 104 is of an L-shaped structure and has a bending arc, which is formed by steel closing. The latch is provided with a locking groove 14 for locking with the bent edge. As Figure 1 and Figure 2 shown, by horizontally sliding the pressing feet, the bent edge is buckled and fixed with the locking groove, which is convenient for installing the back pressing plate.

[0045] Furthermore, the back pressing plate 1 is also provided with a connecting portion 13 connecting the pressing feet 11 and the supporting feet 12, and fasteners such as bolts can be connected to fix the back pressing plate to form a pressing plate assembly. A high-position section 131 is provided in the middle of the connecting portion 13. A first strengthening section 132 connected to the pressing feet is provided on the first side of the high-position section, and a second strengthening section 133 connected to the supporting feet is provided on the second side. The first strengthening section and the second strengthening section are used to increase the overall structural strength of the back pressing plate.

[0046] Specifically, the bottom surfaces of the pressing feet 11 and the first strengthening section 132 both extend horizontally, and the bottom surface of the first strengthening section is higher than the bottom surface of the pressing feet. A convex edge 112 extending downward below the bottom surface of the first strengthening section is provided at the bottom of the pressing feet, and the convex edge 112 cooperates with the bottom surface of the first strengthening section 132 to form a locking groove 14. The bottom surface of the first strengthening section can also play a role in limiting the bent edge.

[0047] Preferably, the first strengthening section 132 and the pressing foot 11 are provided with a longitudinally penetrating hollow cavity 15. A top groove is formed between the first strengthening section, the second strengthening section and the high-position section. This can not only save materials and reduce costs, but also has the effect of increasing strength.

[0048] Furthermore, the top surfaces of the pressing foot 11 and the first strengthening section 132 extend obliquely upward to the high-position section and form an integral slope 16; the bottom surface of the pressing foot 11 is provided with an anti-slip concave-convex surface 111. The design of the integral slope can save materials and there is no need to design this part too high, while the anti-slip concave-convex surface is used to increase friction so that the back pressure plate is not easy to slide. The top surface of the second strengthening section 133 is provided with a strengthening groove 17; this can not only save materials and reduce costs, but also has the effect of increasing strength. The second strengthening section is arc-transitionally connected to the high-position section and the support feet.

[0049] Preferably, the back pressure plate 1 is made of stainless steel or aluminum alloy profile. This not only prevents rust and extends the service life, but also has the advantage of low mass production cost. The upper part of the B side of the frame is provided with a bending structure 105 for clamping the photovoltaic panel in cooperation with the A side, which also has the effect of increasing the front strength of the overall structure of the frame. The cross-section of the support foot is a T-shaped structure, so the support area at the bottom is increased to provide stable support for the back pressure plate.

[0050] As described above, it is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
