Technical Field

[0001] This application relates to the technical field of photovoltaic power generation, and more specifically, to a fixture and a photovoltaic module. Background Art

[0002] Photovoltaic modules are usually fixed on purlins through fixtures and thus installed on the roof. In winter, snow easily accumulates on the photovoltaic modules. Since the photovoltaic modules are usually inclined, the accumulated snow easily slides off, posing a safety hazard. Summary of the Utility Model

[0003] Embodiments of this application provide a fixture and a photovoltaic module.

[0004] The fixture according to the embodiments of this application is used to fix a photovoltaic module on a purlin. The fixture includes a support plate, a pressing block, and a fastener. The fastener tightly connects the support plate and the pressing block so that the pressing block presses the photovoltaic module and the purlin against the support plate. The pressing block includes a baffle, and the baffle extends in a direction away from the photovoltaic module and is configured to cut the snow on the photovoltaic module.

[0005] The fixture in the embodiments of this application can fix a photovoltaic module on a purlin. In addition, by providing a baffle on the pressing block of the fixture, when the snow on the photovoltaic module slides off, the baffle will cut the snow into small pieces, thus avoiding the generation of large-area falling snow, reducing the weight of the falling snow, and reducing the safety hazard caused by the falling snow.

[0006] In some embodiments, the support plate includes a first connecting portion and a first clamping portion. The first connecting portion is used to connect the fastener, and the first clamping portion is used to clamp the photovoltaic module. The support plate further includes a first limiting portion, and the first limiting portion is arranged on the side of the support plate that bears the purlin and is used to limit the position of the purlin.

[0007] In this way, the position of the purlin can be limited by the first limiting portion, avoiding damage to the purlin caused by incorrect installation position of the purlin.

[0008] In some embodiments, the support plate further includes a second limiting portion, and the second limiting portion is arranged on the side of the support plate away from the purlin and is used to limit the installation position of the fixture.

[0009] In this way, the installation position of the fixture can be limited by the second limiting portion, thereby limiting the installation position of the photovoltaic module.

[0010] In some embodiments, the support plate further includes an anti-slip portion, and the anti-slip portion is arranged on the side of the first clamping portion in contact with the purlin.

[0011] Thus, the anti-slip portion is provided to prevent the purlin from slipping out of the fixture during the clamping process.

[0012] In some embodiments, the pressing block includes a second connecting portion and a second clamping portion. The second connecting portion includes a first support plate, a connecting plate, and a second support plate. One end of the connecting plate is connected to the first support plate, and the other end of the connecting plate is connected to the second support plate. The first support plate and the second support plate are located on both sides of the connecting plate. The second clamping portion is provided at one end of the second support plate away from the connecting plate. A first through hole is provided on the connecting plate, and the first through hole is located between the first support plate and the second support plate. The first support plate is configured to be pressed against the pallet when the fastener passes through the first through hole to fasten and connect the pallet and the pressing block.

[0013] Thus, when the fastener fastens and connects the pallet and the pressing block, the first support plate presses against the pallet to form a fulcrum, so that the second clamping portion can obtain a greater clamping force.

[0014] In some embodiments, the angle between the second clamping portion and the second support plate is 80° - 90°.

[0015] Thus, the second clamping portion inclines downward to facilitate better clamping of the purlin.

[0016] In some embodiments, the second support plate extends upward to form the baffle.

[0017] Thus, the baffle and the second support plate are integrally formed, which is convenient for processing.

[0018] In some embodiments, the baffle includes a protruding portion, and the protruding portion is provided at an end of the baffle away from the second clamping portion.

[0019] Thus, the protruding portion can improve the structural strength of the baffle and can also assist in cutting snow.

[0020] In some embodiments, the baffle further includes a reinforcing portion, and the reinforcing portion is provided on a side of the second support plate and the baffle away from the second clamping portion.

[0021] Thus, the reinforcing portion can improve the structural strength of the second support plate and the baffle.

[0022] In some embodiments, the reinforcing portion is arc-shaped, and a hollow is formed between the reinforcing portion and the second support plate and the baffle.

[0023] Thus, the arc-shaped reinforcing portion has higher strength, and at the same time, the formation of the hollow is beneficial to saving production materials and reducing production costs.

[0038] Photovoltaic modules are usually fixed on purlins by clamps and thus installed on the roof. In winter, snow easily accumulates on the photovoltaic modules. Since the photovoltaic modules are usually inclined, the accumulated snow easily slides off, posing a safety hazard.

[0039] Please refer to Figure 1 , an embodiment of the present application provides a photovoltaic module 100, including a photovoltaic component 10, a purlin 20, and a clamp 30. The clamp 30 clamps the purlin 20 so that the purlin 20 is installed at the edge of the photovoltaic component 10. The clamp 30 includes a support plate 31, a pressing block 32, and a fastener 33. The fastener 33 tightly connects the support plate 31 and the pressing block 32 so that the pressing block 32 presses the photovoltaic component 10 and the purlin 20 against the support plate 31. The pressing block 32 includes a baffle 323, and the baffle 323 extends in a direction away from the photovoltaic component 10 and is configured to cut the snow accumulated on the photovoltaic component 10.

[0040] The clamp 30 in the embodiment of the present application can fix the photovoltaic component 10 on the purlin 20. In addition, by providing the baffle 323 on the pressing block 32 of the clamp 30, when the snow accumulated on the photovoltaic component 10 slides off, the baffle 323 will cut the snow into small pieces, thus avoiding the generation of large-area falling snow, reducing the weight of the falling snow, and reducing the safety hazard brought by the falling snow.

[0041] Please refer to Figure 1 and Figure 2 , specifically, the photovoltaic component 10, also known as a solar panel or a photovoltaic panel, is a device that converts sunlight into electrical energy. It is the core part of a solar power generation system, responsible for converting solar energy into direct current electrical energy and providing power for various applications.

[0042] The purlin 20 generally refers to a metal material perpendicular to the photovoltaic component 10 and used to fix the photovoltaic component 10. It is usually located on both sides or around the photovoltaic component 10 and is one of the important materials of the photovoltaic component 10. It plays a key role in supporting and fixing the photovoltaic component 10.

[0043] In the embodiments of the present application, since the photovoltaic module 10 is usually inclined, the fixture 30 can be installed on the purlin 20 at the lowest position of the photovoltaic module 10. When snow begins to accumulate on the photovoltaic module 10, affected by gravity, the snow will slide downward along the upper surface of the photovoltaic module 10. At this time, the baffle 323 extending in the direction away from the photovoltaic module 10 will support the lower part of the snow. When the snow reaches a certain weight, the part of the baffle 323 in contact with the snow will break because it cannot bear the overweight snow, so that the snow can continue to slide along the photovoltaic module 10, and the position where the snow contacts the baffle 323 will be cut open by the baffle 323, causing the sliding snow to be divided into two pieces. Further, a plurality of fixtures 30 can be evenly installed on the purlin 20 at the lowest position of the photovoltaic module 10, so as to divide the snow into more pieces and reduce the volume of the snow.

[0044] In the embodiments of the present application, when the fastener 33 tightly connects the support plate 31 and the pressing block 32, a clamping space for fixing the purlin 20 is formed between the support plate 31 and the pressing block 32. And as the fastener 33 continues to be tightened, the clamping space can be gradually reduced so as to stably clamp the purlin 20.

[0045] Further, the fastener 33 can be selected from screw nuts, rivets, pins, etc. In the embodiments of the present application, the fastener 33 is a screw nut.

[0046] In some embodiments, the support plate 31 and the pressing block 32 can also be connected by other connection methods. Optionally, the connection method between the support plate 31 and the pressing block 32 can also be welding, mortise and tenon connection, snap connection, threaded connection, etc. The specific connection method can be selected according to actual needs and will not be elaborated here.

[0047] In some embodiments, the support plate 31 and the pressing block 32 can also be set as an integrally formed structure, and elastic deformation is generated on the support plate 31 and the pressing block 32 by the compression of the fastener 33 to compress the clamping space, so as to realize the fixation of the purlin 20.

[0048] Please refer to Figure 3 and Figure 4 , in some embodiments, the support plate 31 includes a first connection portion 311 and a first clamping portion 312. The first connection portion 311 is used to connect the fastener 33, and the first clamping portion 312 is used to clamp the photovoltaic module 10. The support plate 31 further includes a first limiting portion 313. The first limiting portion 313 is arranged on the side of the support plate 31 bearing the purlin 20, and the first limiting portion 313 is used to limit the position of the purlin 20.

[0049] In this way, the position of the purlin 20 can be limited by the first limiting portion 313, avoiding damage to the purlin 20 caused by incorrect installation position of the purlin 20.

[0050] Specifically, in the embodiment of the present application, the support plate 31 is an integral structure formed by integral processing, and the support plate 31 is in the shape of a rectangular plate, one end of which is a first connecting portion 311, and the other end is a first clamping portion 312. The first connecting portion 311 is also provided with a second through hole 3111, and the second through hole 3111 is used to install a fastener 33. Further, in the embodiment of the present application, the number of fasteners 33 is two, and therefore, the number of second through holes 3111 is two, and the second through holes 3111 and the fasteners 33 are arranged one by one.

[0051] In the embodiment of the present application, the support plate 31 further includes a first position-limiting portion 313, which is a long strip-shaped protrusion and is located at the boundary between the first connecting portion 311 and the first clamping portion 312. Further, the height of the first position-limiting portion 313 is approximately equal to the thickness of the support plate 31, so that while ensuring the position-limiting function of the first position-limiting portion 313, it is helpful to reduce the difficulty of processing, and a large number of production defects will not be caused due to the excessive height of the first position-limiting portion 313.

[0052] In other embodiments, the first limiting portion 313 may also be designed to be other shapes and / or other sizes, which can be selected according to actual needs and will not be elaborated herein.

[0053] In some embodiments, the first limiting portion 313 can also be formed by separate processing and installed on the support plate 31 through fastening parts. The specific type of fastening parts or the installation form of the first limiting portion 313 can be selected according to actual needs and will not be elaborated here.

[0054] See also Figure 3 and Figure 4 In some embodiments, the support plate 31 further includes a second limiting portion 314 , which is disposed on a side of the support plate 31 away from the purlin 20 , and is used to limit the installation position of the clamp 30 .

[0055] In this way, the installation position of the clamp 30 can be limited by the second limiting portion 314 , thereby limiting the installation position of the photovoltaic assembly 10 .

[0056] Specifically, when the photovoltaic assembly 10 is actually installed and used, the second limiting portion 314 can be used to limit the installation position of the clamp 30 to limit the installation position of the photovoltaic assembly 10 .

[0057] In some embodiments, the photovoltaic assembly 10 is installed at the installation position by means of a mounting frame. When the photovoltaic assembly 10 is installed on the mounting frame, the second limiting portion 314 abuts against the mounting frame to limit and fix the installation position of the photovoltaic assembly 10 .

[0058] In the embodiment of the present application, the pallet 31 further includes a second limiting portion 314. The second limiting portion 314 is a strip-shaped protrusion and is located on the surface of the pallet 31 facing away from the first limiting portion 313. Further, the height of the second limiting portion 314 is approximately equal to the thickness of the pallet 31. In this way, while ensuring the limiting function of the second limiting portion 314, it is beneficial to reduce the processing difficulty and avoid a large number of production defects caused by the excessive height of the second limiting portion 314.

[0059] In the embodiment of the present application, the number of the second limiting portions 314 is two. The two second limiting portions 314 are respectively arranged at the bottoms of the first connecting portion 311 and the first clamping portion 312, and are located on both sides of the second through hole 3111 and the first limiting portion 313.

[0060] In other embodiments, the second limiting portion 314 can also be designed with other numbers, shapes, and / or sizes, which can be specifically selected according to actual needs and will not be elaborated here.

[0061] In some embodiments, the second limiting portion 314 can also be formed by split processing and installed on the pallet 31 through fastening parts. The form of the specific fastening parts or the installation form of the second limiting portion 314 can be selected according to actual needs and will not be elaborated here.

[0062] Please refer to Figure 4 , in some embodiments, the pallet 31 further includes an anti-slip portion 315. The anti-slip portion 315 is arranged on the side where the first clamping portion 312 contacts the purlin 20.

[0063] In this way, the anti-slip portion 315 can prevent the purlin 20 from slipping out of the fixture 30 during the clamping process.

[0064] Specifically, the anti-slip portion 315 is provided on the surface of the first clamping portion 312 that abuts against the purlin 20. In the embodiment of the present application, the anti-slip portion 315 is a toothed anti-slip pattern provided on the surface of the first clamping portion 312 that abuts against the purlin 20. In other embodiments of the application, the anti-slip pattern can also be selected in other forms, such as a linear anti-slip pattern, a convex dot anti-slip pattern, etc.

[0065] In some embodiments of the application, the anti-slip portion 315 can also be a part separated from the pallet 31. That is, the anti-slip portion 315 can be an anti-slip pad or an anti-slip strip provided on the surface of the first clamping portion 312 that abuts against the purlin 20. Optionally, the material of the anti-slip pad or the anti-slip strip is rubber, latex, plastic, or foam, etc. Further, anti-slip patterns can also be provided on the anti-slip pad or the anti-slip strip to further enhance the anti-slip effect. Optionally, the anti-slip pattern is a toothed anti-slip pattern, a linear anti-slip pattern, a convex dot anti-slip pattern, etc.

[0066] In some embodiments, it is also possible to detachably mount the purlin 20 on the supporting plate 31. For example, a third through-hole can be formed in the first clamping portion 312, and a fourth through-hole can be formed at the bottom of the purlin 20. The supporting plate 31 and the purlin 20 are connected by fasteners passing through the third through-hole and the fourth through-hole to achieve a rigid connection, so as to prevent the purlin 20 from detaching from the fixture 30 during use. It is easy to understand that the supporting plate 31 and the purlin 20 can also be connected by other detachable connection methods, such as snap connection, mortise and tenon connection, etc. The specific connection method can be selected according to actual needs and will not be elaborated here.

[0067] In some embodiments, it is also possible to non-detachably mount the purlin 20 on the supporting plate 31. Specifically, the supporting plate 31 and the purlin 20 can be connected by means of adhesive bonding, welding, etc. It should be noted that this method is not applicable to the case where the photovoltaic module 10 needs to be frequently disassembled. The specific connection method can be selected according to actual needs and will not be elaborated here.

[0068] Please refer to Figure 5 and Figure 6 , in some embodiments, the pressing block 32 includes a second connecting portion 321 and a second clamping portion 322. The second connecting portion 321 includes a first supporting plate 3211, a connecting plate 3212, and a second supporting plate 3213. One end of the connecting plate 3212 is connected to the first supporting plate 3211, and the other end of the connecting plate 3212 is connected to the second supporting plate 3213. The first supporting plate 3211 and the second supporting plate 3213 are located on both sides of the connecting plate 3212. The second clamping portion 322 is provided at one end of the second supporting plate 3213 away from the connecting plate 3212. A first through-hole 3214 is formed in the connecting plate 3212, and the first through-hole 3214 is located between the first supporting plate 3211 and the second supporting plate 3213. The first supporting plate 3211 is configured to be pressed against the supporting plate 31 when the fastener 33 passes through the first through-hole 3214 to fasten and connect the supporting plate 31 and the pressing block 32.

[0069] In this way, when the fastener 33 fastens and connects the supporting plate 31 and the pressing block 32, the first supporting plate 3211 is pressed against the supporting plate 31 to form a fulcrum, so that the second clamping portion 322 can obtain a greater clamping force.

[0070] Specifically, in the embodiment of the present application, the pressing block 32 is an integrally formed one-piece structure. The first supporting plate 3211 and the second supporting plate 3213 are respectively provided at both ends of the connecting plate 3212. The first supporting plate 3211 and the second supporting plate 3213 are parallel to each other and extend in opposite directions. When the fastener 33 fastens and connects the supporting plate 31 and the pressing block 32, the first supporting plate 3211 is pressed against the supporting plate 31 to form a fulcrum, and the pressing block 32 as a whole forms a lever structure to transmit the fastening force of the fastener 33 to the second clamping portion 322.

[0071] Further, in order to enhance the structural strength of the first support plate 3211 and avoid damaging the support plate 31 by the first support plate 3211, a resisting portion is provided at the end of the first support plate 3211 in contact with the support plate 31. The resisting portion is in the shape of a long strip plate, the width of the resisting portion is greater than that of the first support plate 3211, and the resisting portion is provided at the end of the first support plate 3211 in contact with the support plate 31 and is perpendicular to the first support plate 3211.

[0072] Further, in order to enhance the strength of the second clamping portion 322, the cross-sectional shape of the second clamping portion 322 is set as a trapezoid, that is, along the end of the second clamping portion 322 to the root of the second clamping portion 322, the thickness of the second clamping portion 322 gradually increases. In the embodiment of the present application, the cross-sectional shape of the second clamping portion 322 is a right trapezoid, wherein the right-angled side of the right trapezoid is close to the purlin 20 to avoid affecting the fixing effect of the second clamping portion 322.

[0073] Further, in order to enhance the strength of the second clamping portion 322, the cross-sectional shape of the second clamping portion 322 can also be set as other shapes that can improve the clamping force, and can be specifically selected according to actual needs, and will not be elaborated here.

[0074] In some embodiments, an anti-slip pad or anti-slip strip can be installed on the surface of the second clamping portion 322 in contact with the purlin 20. Optionally, the material of the anti-slip pad or anti-slip strip is rubber, latex, plastic, foam, etc. Further, anti-slip patterns can also be provided on the anti-slip pad or anti-slip strip for further enhancing the anti-slip effect. Optionally, the anti-slip patterns are tooth-shaped anti-slip patterns, linear anti-slip patterns, convex dot anti-slip patterns, etc.

[0075] In some embodiments, anti-slip patterns can be directly provided on the surface of the second clamping portion 322 in contact with the purlin 20. Optionally, the anti-slip patterns can be tooth-shaped anti-slip patterns, linear anti-slip patterns, convex dot anti-slip patterns, etc.

[0076] Please refer to Figure 6 , in some embodiments, the included angle between the second clamping portion 322 and the second support plate 3213 is 80° to 90°.

[0077] In this way, the second clamping portion 322 inclines downward to facilitate better clamping of the purlin 20.

[0078] Specifically, the included angle between the bottom surface of the second clamping portion 322 and the second support plate 3213 is 80° to 90°. In the embodiment of the present application, the cross-sectional shape of the second clamping portion 322 is a right trapezoid, and the included angle between the bottom surface of the second clamping portion 322 and the second support plate 3213 is 90°. In other embodiments, the cross-sectional shape of the second clamping portion 322 can also be non-right trapezoid. At this time, the included angle between the bottom surface of the second clamping portion 322 and the second support plate 3213 can be less than 90°.

[0079] In some embodiments, the angle between the second clamping portion 322 and the second support plate 3213 may also be 0 to 90°. Specifically, the angle between the second clamping portion 322 and the second support plate 3213 can be selected according to the objective reasons and actual requirements of the shape of the purlin 20, and will not be elaborated here.

[0080] Please refer to Figure 5 and Figure 6 , in some embodiments, the second support plate 3213 extends upward to form a baffle 323.

[0081] In this way, the baffle 323 and the second support plate 3213 are integrally formed, which is convenient for processing.

[0082] Specifically, in the embodiment of the present application, the second support plate 3213 extends upward to form a baffle 323. When the fixture 30 is installed on the photovoltaic module 10, the snow sliding along the photovoltaic module 10 will be cut by the baffle 323, thereby reducing its volume.

[0083] In some embodiments, the baffle 323 may also be a separate component. The baffle 323 is disposed on the top of the pressing block 32 and extends away from the pressing block 32. Preferably, the baffle 323 is disposed at the topmost part of the pressing block 32 and extends upward.

[0084] In some embodiments, the baffle 323 includes a protruding portion 324, and the protruding portion 324 is disposed at an end of the baffle 323 away from the second clamping portion 322.

[0085] In this way, the protruding portion 324 can improve the structural strength of the baffle 323 and at the same time assist in cutting snow.

[0086] Specifically, the protruding portion 324 is disposed at an end of the baffle 323 away from the second clamping portion 322 and is located on the side close to the photovoltaic module 10. In the embodiment of the present application, the protruding portion 324 protrudes away from the baffle 323 in a long strip rib shape and forms a 90° angle with the baffle 323, so as to play a role in cutting and breaking ice when the snow slides.

[0087] Preferably, a sharp angle can be designed on the side of the protruding portion 324 away from the baffle 323 to facilitate better cutting of snow and breaking ice.

[0088] Please refer to Figure 5 and Figure 6 , in some embodiments, the baffle 323 further includes a reinforcing portion 325, and the reinforcing portion 325 is disposed on the side of the second support plate 3213 and the baffle 323 away from the second clamping portion 322.

[0089] In this way, the reinforcing portion 325 can improve the structural strength of the second support plate 3213 and the baffle 323.

[0090] Specifically, in the embodiments of the present application, the pressing block 32 further includes a reinforcing portion 325. The reinforcing portion 325 is disposed on the side of the second support plate 3213 and the baffle 323 away from the second clamping portion 322, with one end connected to the second support plate 3213 and the baffle 323, and the other end connected to the connecting plate 3212.

[0091] In some embodiments, the reinforcing portion 325 may be a reinforcing rib. The reinforcing rib may be in the shape of a right triangle. One right side of the right triangle-shaped reinforcing rib is connected to the connecting plate 3212, and the other right side is connected to the second support plate 3213 or the baffle 323. The thickness of the reinforcing rib is approximately equal to the thickness of the connecting plate 3212, the second support plate 3213, or the baffle 323. Further, the number of reinforcing ribs may be multiple, and the multiple reinforcing ribs are arranged at intervals.

[0092] In some embodiments, the reinforcing portion 325 may be a reinforcing rib. The reinforcing rib may be in the shape of a trapezoid. One side of the trapezoid-shaped reinforcing rib is connected to the connecting plate 3212, and the other side is connected to the second support plate 3213 or the baffle 323. The thickness of the reinforcing rib is approximately equal to the thickness of the connecting plate 3212, the second support plate 3213, or the baffle 323. Further, the number of reinforcing ribs may be multiple, and the multiple reinforcing ribs are arranged at intervals.

[0093] Please refer to Figure 6 , in some embodiments, the reinforcing portion 325 is arc-shaped, and a hollow is formed between the reinforcing portion 325 and the second support plate 3213 and the baffle 323.

[0094] In this way, the arc-shaped reinforcing portion 325 has higher strength, and at the same time, the formation of the hollow is beneficial to saving production materials and reducing production costs.

[0095] Specifically, in the embodiments of the present application, the reinforcing portion 325 is arc-shaped. It is easy to understand that the arc-shaped reinforcing portion 325 has relatively greater strength compared to the reinforcing portions 325 of other shapes, and is more material-saving. In addition, the appearance is also more beautiful.

[0096] Further, one end of the arc-shaped reinforcing portion 325 is connected to the end of the baffle 323, and the other end is connected to the connecting plate 3212. A hollow is formed between the reinforcing portion 325 and the second support plate 3213 and the baffle 323. Further, the pressing block 32 further includes a plurality of support ribs. One end of the support rib is connected to the reinforcing portion 325, and the other end is connected to the second support plate 3213 or the baffle 323, thereby dividing the hollow into multiple regions to further increase the strength of the reinforcing portion 325.
