Abstract
Description
Technical Field
[0001] This utility model relates to the field of rooftop photovoltaic installation technology, specifically to photovoltaic clamps and rooftop photovoltaic systems. Background Technology
[0002] The development of distributed photovoltaic (PV) systems on industrial and commercial rooftops is rapid, with corrugated steel roofs being the most common type of roof in these settings, accounting for a large share of installations. PV fixtures are a crucial component of rooftop PV systems and a significant factor influencing power plant costs and construction timelines.
[0003] The common method for installing photovoltaics on corrugated steel roofs involves fixing brackets to the surface of the corrugated steel roof, installing long guide rails on the brackets, and then using clamps to secure the photovoltaic modules to the guide rails. However, the guide rails are often several meters long, making transportation and installation inconvenient and resulting in high implementation costs.
[0004] To address this, some related technologies have replaced long guide rails with short guide rails that are integrally molded with the bracket. This reduces the number of parts and lowers manufacturing and transportation costs. However, the short guide rails make the photovoltaic modules less securely fixed, increasing the risk of positional displacement during the use of the photovoltaic modules. Utility Model Content
[0005] In view of this, the present invention provides a photovoltaic clamp and a roof photovoltaic system to solve the problem of insufficiently secure fixing of photovoltaic modules.
[0006] In a first aspect, this utility model provides a photovoltaic clamp, including a bracket, a clamping weight, and a first fastening assembly. The bracket extends in a first direction and is used to be mounted on a roof. The bracket includes a support plate and two first side plates, which are spaced apart in a second direction, forming a first connecting groove between them. The support plate is mounted on top of the first side plates and is used to support a photovoltaic module. The surface of the support plate supporting the photovoltaic module is provided with friction teeth. The clamping weight extends in the second direction and is used to be mounted on the support plate to press the photovoltaic module. The first fastening assembly includes a first fastener and a second fastener. The second fastener is disposed in the first connecting groove. The first fastener passes through the clamping weight and the support plate to connect the second fastener, so that the clamping weight presses the photovoltaic module.
[0007] Beneficial effects: First, the photovoltaic clamp uses a tray to support the photovoltaic module. The interaction between the first and second fasteners causes the pressure plate to press against the tray, thereby securing the photovoltaic module. The photovoltaic clamp does not require a continuous guide rail, which helps reduce the number of parts and lowers manufacturing and transportation costs. Second, the tray increases the contact area between the bracket and the photovoltaic module, as well as between the bracket and the pressure plate, which helps increase friction and thus securely fix the photovoltaic module. Finally, the friction teeth form an uneven contact surface on the tray, which further increases the contact area between the bracket and the photovoltaic module, as well as between the bracket and the pressure plate, after clamping, which helps to secure the photovoltaic module even more firmly.
[0008] In one optional embodiment, the number of trays is two, the two trays are symmetrically arranged on the two first side plates, the two trays are spaced apart from each other in the second direction, and the entrance to the first connecting groove is formed between the two trays.
[0009] Beneficial effects: On the one hand, the symmetrically designed trays can support photovoltaic modules more evenly and avoid the brackets from being subjected to bending moments; on the other hand, the entry points formed between the trays allow the first fastener to pass directly through the entry point to connect to the second fastener, eliminating the need to drill through holes in the trays, simplifying the installation process of photovoltaic modules and making the use of photovoltaic clamps more convenient.
[0010] In one alternative embodiment, a cable passage groove is formed between the two first side plates, and the bracket further includes a first flange disposed on the first side plate, the first flange separating the first connecting groove and the cable passage groove.
[0011] Beneficial effects: The installation of cable trays makes it easier to store and organize the cables connecting the photovoltaic modules, making the wiring of the photovoltaic modules more standardized and orderly.
[0012] In one optional embodiment, the bracket further includes a first base plate and two second side plates. The first side plate is disposed on one side of the first base plate, and the second side plates are disposed on the other side of the first base plate. The two second side plates are spaced apart in the second direction, and a second connecting groove is formed between the second side plates for embedding the corrugated roof.
[0013] Beneficial effects: First, the corrugated section has relatively higher strength and resistance to deformation. The bracket is set on the corrugation through the second connecting groove, which helps the roof better bear the weight of the photovoltaic modules. Second, this setting makes the position of the first connecting groove higher than the corrugation, which helps to prevent the first connecting groove from being submerged in rainwater. Finally, at this time, the first direction is parallel to the extension direction of the corrugation, and the second direction is perpendicular to the corrugation direction. Therefore, the clamps press the upper and lower sides of the photovoltaic modules tightly, making it suitable for the photovoltaic modules to be arranged with the short side along the corrugation direction, which helps to improve the photovoltaic coverage rate of the roof.
[0014] In an alternative embodiment, a second fastening assembly is further included, the second fastening assembly including a third fastener that connects to the corrugation through the second side plate.
[0015] Beneficial effect: The third fastener passes through the corrugated roof, which helps to prevent the perforation of the third fastener from being submerged in rainwater, reducing the risk of roof leaks.
[0016] In an alternative embodiment, a sealing gasket is also included, which is disposed between the second side plate and the corrugations.
[0017] Beneficial effects: Installing a sealing gasket can further improve the sealing effect between the third fastener and the corrugated sheet, reducing the risk of roof leaks.
[0018] In an alternative embodiment, a sealant is further included, disposed within the second connecting groove, to connect the second side plate and the corrugated plate.
[0019] Beneficial effects: Using adhesive bonding can prevent perforations in the roof and reduce the risk of roof leaks.
[0020] In one optional embodiment, the first direction is parallel to the extension direction of the corrugations of the roof. The pressure plate includes a third side plate, a second bottom plate, and a pressure plate. The third side plate is used to contact and position the side of the photovoltaic module. The pressure plate is disposed on the top of the third side plate and is located on the side of the third side plate facing the photovoltaic module. The second bottom plate is disposed at the bottom of the third side plate and is located on the side of the third side plate away from the photovoltaic module.
[0021] Beneficial effect: The force exerted by the photovoltaic module on the pressure plate located on the lower side can generate a component force that presses the second base plate against the support plate, thereby enhancing the friction between the pressure plate and the support plate and preventing the pressure plate from loosening.
[0022] In one alternative embodiment, the pressure plate includes a second flange disposed at the bottom of the second base plate and located at one end of the second base plate away from the third side plate.
[0023] Beneficial effects: The second flange allows for a certain gap between the second base plate and the support plate, which facilitates the compensation of assembly errors. At the same time, the second flange reduces the contact area and increases the pressure of the pressure bar on the support plate, which helps to make the connection between the pressure bar and the support plate more secure.
[0024] Secondly, this utility model also provides a roof photovoltaic system, including a roof, photovoltaic modules, and a photovoltaic clamp provided by this utility model. The photovoltaic clamp is disposed on the roof, and the photovoltaic modules are disposed on the photovoltaic clamp.
[0025] Beneficial effects: The roof photovoltaic system includes the photovoltaic clamp provided by this utility model, and therefore has the corresponding beneficial effects brought by the photovoltaic clamp, which will not be elaborated here. Attached Figure Description

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.
[0034] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.
[0035] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium.

The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.
[0037] Common photovoltaic module installation methods require the use of long guide rails. The guide rails are first installed on the bracket 101, and then multiple photovoltaic modules 3 are installed on the same guide rail. The excessive length of the guide rails makes transportation and assembly inconvenient and increases implementation costs. Furthermore, the guide rail specifications limit the lead time for stocking, resulting in lower installation efficiency and a longer construction period.
[0038] Some related technologies integrate the structure of the guide rail and the bracket together, with each photovoltaic module placed on its corresponding bracket, effectively reducing implementation costs. However, compared to the guide rail installation method, the contact area between the photovoltaic module and the bracket is reduced, the friction force provided by the bracket to the photovoltaic module is reduced, and the photovoltaic module is more prone to slippage relative to the bracket, resulting in decreased installation reliability.
[0039] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.
[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 According to an embodiment of the present invention, a photovoltaic clamp 1 is provided, including a bracket 101, a clamp 102, and a first fastening assembly. The bracket 101 extends in a first direction and is used to be mounted on a roof 2. The bracket 101 includes a support plate 1011 and two first side plates 1012, which are spaced apart in a second direction. A first connecting groove 1013 is formed between the two first side plates 1012. The support plate 1011 is disposed on the top of the first side plates 1012 and is used to support... The photovoltaic module 3 is supported by a support plate 1011. The surface of the support plate 1011 is provided with friction teeth. The pressure bar 102 extends in the second direction and is used to be set on the support plate 1011 to press the photovoltaic module 3. The first fastening component includes a first fastener 1031 and a second fastener 1032. The second fastener 1032 is set in the first connecting groove 1013. The first fastener 1031 passes through the pressure bar 102 and the support plate 1011 to connect the second fastener 1032 so that the pressure bar 102 presses the photovoltaic module 3.
[0041] During assembly, multiple photovoltaic clamps 1 are set on the roof 2, and the multiple photovoltaic clamps 1 press the photovoltaic modules 3 from different positions, thereby fixing the photovoltaic modules 3.
[0042] First, the photovoltaic clamp 1 uses the support plate 1011 to support the photovoltaic module 3. The first fastener 1031 and the second fastener 1032 interact to press the pressure bar 102 against the support plate 1011, thereby tightening the photovoltaic module 3. The photovoltaic clamp 1 serves the dual purpose of roof anchoring and fixing the photovoltaic module 3. It does not require a continuous guide rail, which helps to reduce the number of parts in the photovoltaic clamp 1, reduce manufacturing and transportation costs, and also helps to shorten the preparation cycle and construction cycle.
[0043] Secondly, the addition of the support plate 1011 increases the contact area between the bracket 101 and the photovoltaic module 3, as well as between the bracket 101 and the pressure plate 102, which helps to increase the friction and thus securely fix the photovoltaic module 3.
[0044] Finally, the friction teeth form an uneven contact surface on the support plate 1011, thereby further increasing the contact area between the bracket 101 and the photovoltaic module 3, as well as between the bracket 101 and the pressure plate 102 after clamping, which helps to fix the photovoltaic module 3 more securely.
[0045] Understandably, the support 101 can be formed by extrusion molding using a mold. Figure 2 , Figure 3 In the illustrated embodiment, the friction teeth also extend in the first direction, making it suitable for direct formation during extrusion molding and simplifying the processing of the support 101. In embodiments not shown, the friction teeth can also be designed in other ways, such as extending in the second direction, or having two sets of friction teeth extending in two intersecting directions to form an interlocking texture, as long as the friction teeth can form an uneven surface. This invention does not limit this.
[0046] In some embodiments, the two first side plates 1012 are symmetrical with respect to the reference plane, and the support plate 1011 is also symmetrical with respect to the reference plane. The support plate 1011 with the symmetrical design can support the photovoltaic module 3 more evenly, so that the force of the photovoltaic module 3 on the bracket 101 is equivalent to the force in the reference plane, and the bracket 101 is not subjected to bending moment.
[0047] Optionally, in some embodiments, there are two trays 1011, which are symmetrically arranged on the two first side plates 1012, thereby achieving symmetry of the trays 1011 with respect to the reference plane. The two trays 1011 are spaced apart in the second direction, and an entrance to the first connecting groove 1013 is formed between the two trays 1011. With the entrance formed between the trays 1011, the first fastener 1031 can directly pass through the entrance to connect to the second fastener 1032, eliminating the need to machine through holes in the trays 1011, simplifying the installation process of the photovoltaic module 3, and making the use of the photovoltaic clamp 1 more convenient.
[0048] Optionally, the first fastener 1031 can be a fastening bolt, and the second fastener 1032 can be a fastening nut, and the fastening nut can also be a T-nut, so as to stably position it in the first connecting groove 1013.
[0049] In some embodiments, a cable tray 1014 is formed between the two first side plates 1012. The bracket 101 also includes a first flange 1015, which is disposed on the first side plate 1012 and separates the first connecting groove 1013 and the cable tray 1014. The cable tray 1014 facilitates the storage and organization of cables connecting the photovoltaic module 3, making the wiring of the photovoltaic module 3 more standardized and orderly.
[0050] Furthermore, referring to Figure 3 In some embodiments, the gap between the first flanges 1015 is greater than the diameter of the first fastener 1031, and the first fastener 1031 can pass through the wire groove 1014, so that the wire groove 1014 is also suitable for compensating for the excessive length of the first fastener 1031, which facilitates the setting of the first fastening assembly.
[0051] In some embodiments, the bracket 101 further includes a first base plate 1016 and two second side plates 1017. The first side plate 1012 is disposed on one side of the first base plate 1016, and the second side plate 1017 is disposed on the other side of the first base plate 1016. The two second side plates 1017 are spaced apart in a second direction, and a second connecting groove is formed between the second side plates 1017. The second connecting groove is used to embed the corrugated 201 of the roof 2.
[0052] Understandably, at this time, the roof 2 is a corrugated steel roof 2. The strength and deformation resistance of the corrugated part 201 on the roof 2 are relatively higher. The bracket 101 is set on the corrugated part 201 through the second connecting groove, which helps the roof 2 to better bear the weight of the photovoltaic module 3 and reduce the adverse effects of concentrated load on the roof 2.
[0053] Furthermore, when it rains, rainwater will flow into the groove formed between two adjacent corrugations 201 and then flow downwards along the direction of the corrugations 201. Setting the bracket 101 on the corrugations 201 so that the position of the first connecting groove 1013 is higher than that of the corrugations 201 helps to prevent the first connecting groove 1013 and the wire passage groove 1014 from being submerged in rainwater.
[0054] In addition, when installing photovoltaic module 3, it is customary to set the support point (that is, the connection point between photovoltaic module 3 and photovoltaic clamp 1) on the long side of photovoltaic module 3 to avoid photovoltaic module 3 forming an excessively long simply supported beam. In some related technologies, the long side of photovoltaic module 3 is along the extension direction of corrugated 201, and the photovoltaic coverage rate of roof 2 needs to be improved.
[0055] Reference Figure 1 and Figure 3 Since the bracket 101 extends in the first direction and the corrugated 201 is embedded in the second connecting groove, the first direction is parallel to the extension direction of the corrugated 201 and the second direction is perpendicular to the direction of the corrugated 201. The pressure bar 102 is suitable for pressing the upper and lower sides of the photovoltaic module 3, so that the photovoltaic module 3 is suitable for adopting an arrangement with the short side along the direction of the corrugated 201, which helps to improve the photovoltaic coverage rate of the roof 2.
[0056] In some embodiments, the photovoltaic clamp 1 further includes a second fastening assembly, which includes a third fastener 1041 that passes through the second side plate 1017 and connects to the corrugated 201. Optionally, the third fastener 1041 can be a self-tapping screw. The self-tapping connection method simplifies the installation process of the photovoltaic module 3 and makes the photovoltaic clamp 1 more convenient to use. At the same time, the third fastener 1041 passes through the roof 2 from the corrugated 201, which helps to prevent the perforation of the third fastener 1041 from being submerged in rainwater and reduces the risk of water leakage from the roof 2.
[0057] In some embodiments, the photovoltaic clamp 1 further includes a sealing gasket 105 disposed between the second side plate 1017 and the corrugated 201. The sealing gasket 105 further improves the sealing effect between the third fastener 1041 and the corrugated 201, reducing the risk of leakage from the roof 2.
[0058] Of course, in addition to using the second fastening component, the connection between the corrugated 201 and the second side panel 1017 can also be achieved by welding, bonding, or other methods. In some embodiments not shown, the photovoltaic clamp 1 also includes sealant, which is disposed in the second connecting groove to connect the second side panel 1017 and the corrugated 201. Using adhesive bonding can avoid forming perforations in the roof 2 and reduce the risk of water leakage in the roof 2.
[0059] In some embodiments, the first direction is parallel to the extension direction of the corrugated 201 of the roof 2. The pressure plate 102 includes a third side plate 1021, a second bottom plate 1022 and a pressure plate 1023. The third side plate 1021 is used to contact and position the side of the photovoltaic module 3. The pressure plate 1023 is disposed on the top of the third side plate 1021 and is located on the side of the third side plate 1021 facing the photovoltaic module 3. The second bottom plate 1022 is disposed at the bottom of the third side plate 1021 and is located on the side of the third side plate 1021 away from the photovoltaic module 3.
[0060] Understandably, the photovoltaic module 3 is placed at an angle on the roof 2. The weight of the photovoltaic module 3 can be decomposed into a first component perpendicular to the support plate 1011 and a second component along a first direction. The reaction force exerted by the support plate 1011 on the photovoltaic module 3 is used to balance the first component. The friction between the photovoltaic module 3 and the support plate 1011, and the reaction force exerted by the third side plate 1021 of the pressure plate 102 located on the lower side of the photovoltaic module 3 on the photovoltaic module 3, are used to balance the second component. The pressure exerted by the photovoltaic module 3 on the third side plate 1021 can generate torque, forming a force that presses the second base plate 1022 against the support plate 1011, thereby increasing the friction between the pressure plate 102 and the support plate 1011 and preventing the pressure plate 102 from loosening.
[0061] In some embodiments, the pressure plate 102 includes a second flange 1024, which is disposed at the bottom of the second base plate 1022 and located at the end of the second base plate 1022 away from the third side plate 1021. The second flange 1024 provides a certain gap between the second base plate 1022 and the support plate 1011, which facilitates compensation for assembly errors. At the same time, the second flange 1024 reduces the contact area and increases the pressure of the pressure plate 102 on the support plate 1011, which helps to make the connection between the pressure plate 102 and the support plate 1011 more secure.
[0062] Secondly, this utility model also provides a roof photovoltaic system, including a roof 2, a photovoltaic module 3, and a photovoltaic clamp 1 provided by this utility model. The photovoltaic clamp 1 is disposed on the roof 2, and the photovoltaic module 3 is disposed on the photovoltaic clamp 1.
[0063] The rooftop photovoltaic system 2 includes the photovoltaic clamp 1 provided by this utility model, and therefore has the beneficial effects brought by the photovoltaic clamp 1, which will not be described in detail here.
[0064] Reference Figure 1 and Figure 3 In some embodiments, the photovoltaic clamps 1 are arranged in pairs, and the two photovoltaic clamps 1 in pairs are placed at intervals on the roof 2 along the direction of the corrugation 201, respectively pressing the upper side and lower side plate of the photovoltaic clamps 1 to realize the installation and fixation of the photovoltaic module 3.
[0065] 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.
