Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a briquetting device and a photovoltaic system. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic (PV) power generation, as a clean and renewable energy source, has been widely applied and promoted. The expanding scale of PV projects has placed higher demands on the installation efficiency, stability, and safety of PV modules. Due to their large area and high power output, full-screen PV modules require more reliable fixing methods during installation to ensure stable operation under various environmental conditions.

[0003] In related technologies, the clamping device of a full-screen photovoltaic module connects two photovoltaic modules by engaging the left and right ends with the mounting grooves on the frame of the side-by-side photovoltaic module. However, the clamping device structure in these technologies requires a large pushing force to clamp the frame onto one end of the clamping device when connecting the photovoltaic modules, resulting in time-consuming and labor-intensive installation.

[0006] The pressing block body is also provided with a support part, which abuts against the photovoltaic module, and the surface of the support part that abuts against the photovoltaic module is an inclined surface.

[0007] In one embodiment, the inclined surface slopes upward from the end of the support near the pressure block body to the end near the photovoltaic module.

[0008] In one embodiment, the support portion is disposed at the bottom of the pressure block, and / or the snap-fit ​​structure is disposed at the top.

[0012] The first support rib and the second support rib have different heights;

[0013] The first direction is the arrangement direction of two adjacent photovoltaic modules.

[0015] The pressure block body is connected to the mounting bracket, the first support rib has a gap with the mounting bracket, and the second support rib presses against the mounting bracket.

[0016] In one embodiment, the snap-fit ​​structure includes a top component extending from the pressure block body and a limiting protrusion provided on the top component;

[0017] The top component can be displaced in the vertical direction, and the limiting protrusion engages with the photovoltaic module.

[0018] In one embodiment, the limiting protrusion is disposed in the middle of the top component and protrudes in a direction away from the support portion.

[0019] In one embodiment, the snap-fit ​​structure and the support portion are located on the same side of the pressure block body.

[0026] The beneficial effects of this utility model are:

[0027] This utility model discloses a pressing device. The pressing block body is used for fixed connection with a mounting bracket, and both ends of the pressing block body are used to snap onto the frames of two adjacent photovoltaic modules, thereby achieving a fixed connection between the two adjacent photovoltaic modules and the mounting bracket, and thus realizing the installation of the photovoltaic modules. By setting a snap-fit ​​structure on the pressing block body, the device snaps onto the photovoltaic module. By setting a support part, the device abuts against the photovoltaic module, thereby achieving the connection between one end of the pressing device and the photovoltaic module under the combined action of the snap-fit ​​structure and the support part. Since the support part and the photovoltaic module limit each other through friction, the abutment is achieved. In this application, by setting the surface of the support part that abuts against the photovoltaic module as an inclined surface, the support part and the photovoltaic module generate friction through contact, thereby ensuring the reliability of the abutment between the two. Furthermore, setting the surface of the support part that abuts against the photovoltaic module as an inclined surface is beneficial for guiding the device when connecting it to the photovoltaic module, thus making the installation of both easier. With the above structure, the contact area between the support and the photovoltaic module is increased by the surface contact between the pressing device and the frame of the photovoltaic module, making the connection between the pressing device and the photovoltaic module more stable and reliable. In addition, by abutting the support against the frame of the photovoltaic module, the mounting groove of the frame is made deeper, which can accommodate the elastic deformation of the mounting body, so that the top part can be engaged with the frame to a greater extent, thereby improving the reliability and stability of the connection between the pressing device and the photovoltaic module.

[0040] See Figure 1 and Figure 2 An embodiment of the present invention provides a pressing device 100, which includes a pressing body 110. The pressing body 110 is provided with a snap-fit ​​structure 160 for snapping with a photovoltaic module 200. The pressing body 110 is also provided with a support part 140, which abuts against the photovoltaic module 200. The surface of the support part 140 that abuts against the photovoltaic module 200 is an inclined surface.

[0041] This technical solution provides a pressing device 100. The pressing body 110 is used to be fixedly connected to the mounting bracket 400. Both ends of the pressing body 110 are respectively used to engage with the frames 300 of two adjacent photovoltaic modules 200, thereby realizing the fixed connection between the two adjacent photovoltaic modules 200 and the mounting bracket 400, and thus realizing the installation of the photovoltaic modules 200. By providing a snap-fit ​​structure 160 on the pressing body 110, the pressing device 100 is engaged with the photovoltaic module 200 through the snap-fit ​​structure 160. By providing a support part 140, the support part 140 abuts against the photovoltaic module 200, thereby achieving the connection between one end of the pressing device 100 and the photovoltaic module 200 under the combined action of the snap-fit ​​structure 160 and the support part 140. Since the support portion 140 and the photovoltaic module 200 are mutually restrained by friction to achieve contact, in this application, by setting the surface of the support portion 140 that abuts against the photovoltaic module 200 as an inclined surface, the support portion 140 and the photovoltaic module 200 generate friction through surface contact, thereby ensuring the reliability of the contact between the two. Furthermore, setting the surface of the support portion 140 that abuts against the photovoltaic module 200 as an inclined surface is beneficial for guiding the connection of the pressing device 100 and the photovoltaic module 200, thereby making the installation of both easier.

[0042] With the above structure, the contact area between the support part 140 and the photovoltaic module 200 is increased by the surface contact between the pressing device 100 and the frame 300 on the photovoltaic module 200 through the surface contact abutment with the photovoltaic module 200, thereby making the connection between the pressing device 100 and the photovoltaic module 200 more stable and reliable. In addition, by abutting the support part 140 against the frame 300 of the photovoltaic module 200, the groove depth of the mounting groove 310 of the frame 300 is increased, thereby accommodating the elastic deformation of the mounting body, so that the top part 161 can be engaged with the frame 300 to a greater extent, thereby improving the reliability and stability of the connection between the pressing device 100 and the photovoltaic module 200.

[0043] It should be noted that the position of the support portion 140 on the pressing block body 110 is not limited; it can be located at the top or bottom of the pressing block body 110. In a specific embodiment, the support portion 140 is located at the bottom of the pressing block body 110, and the snap-fit ​​structure 160 is located at the top of the pressing block body 110.

[0044] It is understood that when the pressing device 100 provided in this application is connected to the frame 300 of the photovoltaic module 200, it is only necessary to align the snap-fit ​​structure 160 and the support part 140 of the pressing device 100 with the mounting groove 310 of the frame 300 of the photovoltaic module 200, and push the pressing device 100 towards the photovoltaic module 200 along the first direction X, that is, the arrangement direction of the two photovoltaic modules 200. The inclined surface of the support part 140 guides the pressing device 100 to snap-fit ​​with the limiting snap protrusion 320 on the frame 300, and the support part 140 abuts against the frame 300.

[0045] See Figure 1 and Figure 2 Furthermore, the inclined surface slopes upward from the end of the support portion 140 near the pressure block body 110 towards the end near the photovoltaic module 200. By setting the inclined surface on the support portion 140 that abuts against the photovoltaic module 200 in the above form, the support portion 140 gradually thickens from the end away from the pressure block body 110 towards the end near the pressure block body 110. This ensures that the inclined surface guides the installation of the pressure block body 110 and the frame 300 of the photovoltaic module 200 while maintaining the structural strength of the support portion 140, thereby ensuring the reliability and stability of the pressure block device 100 after it is connected to the photovoltaic module 200.

[0046] The specific structure of the pressing block body 110 is not limited. In this embodiment, the pressing block body 110 includes a base plate 111 and support plates 112 disposed at opposite ends of the base plate 111, with the two support plates 112 disposed on the same side of the base plate 111. A support portion 140 is disposed at one end of the base plate 111 along the first direction X.

[0047] In one embodiment, a first support rib 120 is provided on the side of the pressure block body 110 away from the snap-fit ​​structure 160; the pressure block body 110 is connected to the mounting bracket 400, there is a gap between the pressure block body 110 and the mounting bracket 400, and the first support rib 120 presses against the mounting bracket 400.

[0048] By providing a first support rib 120 on the side of the pressure block body 110 away from the snap-fit ​​structure 160, when assembling two adjacent photovoltaic modules 200 together, the end of the pressure block body 110 without the first support rib 120 can press against the frame 300 on the corresponding photovoltaic module 200. This makes the connection between the frame 300 on the photovoltaic module 200 and the end of the corresponding pressure block body 110 more secure and reliable, thereby improving the stability of the connection between the frame 300 and the mounting bracket 400. For the end of the pressure block body 110 with the first support rib, since the first support rib is supported on the mounting bracket, there is a gap between the side of the pressure block body at the corresponding end and the mounting bracket. This gap allows for the bottom insertion of the frame. Thus, while ensuring the reliability and stability of the connection between one side of the frame 300 and the pressure block device 100, it makes the installation of the other side of the frame 300 and the pressure block device 100 easier. The above structure not only ensures the reliability of the connection between the pressing device 100 and the frame 300, and the reliability of the connection between the frame 300 and the mounting bracket 400, but also makes the connection between the frame 300 and the pressing device 100 more convenient.

[0049] See Figure 1 and Figure 2 In one embodiment, the pressure block body 110 is provided with a first support rib 120 and a second support rib 130 on the side away from the snap-fit ​​structure 160; the first support rib 120 and the second support rib 130 are spaced apart along a first direction X; wherein the first support rib 120 and the second support rib 130 have different heights; the first direction X is the arrangement direction of two adjacent photovoltaic modules 200.

[0050] By providing a first support rib 120 and a second support rib 130 spaced apart along the first direction X on the side of the pressure block body 110 away from the snap-fit ​​structure 160, and setting the heights of the first support rib 120 and the second support rib 130 to different forms, it is possible to assemble two adjacent photovoltaic modules 200 together. The lower-height support ribs correspond to one end of the pressure block body 110, which can press against the frame 300 on the corresponding photovoltaic module 200. This makes the connection between the frame 300 on the photovoltaic module 200 and the end of the corresponding pressure block body 110 more secure and reliable, thereby improving the stability of the connection between the frame 300 and the mounting bracket 400. For the higher-height support ribs, the relatively high height of the support ribs results in a larger space between the bottom surface of the pressure block body 110 and the mounting bracket 400. This allows for greater space between the bottom of the pressure block body 110 and the mounting bracket 400 when the frame 300 on another photovoltaic module 200 is engaged with the corresponding pressure block body 110. This facilitates the insertion of the bottom of the frame 300, ensuring the reliability and stability of the connection between one side of the frame 300 and the pressure block device 100, while making the installation of the other side of the frame 300 and the pressure block device 100 easier. The above structure not only ensures the reliability of the connection between the pressing device 100 and the frame 300, and the reliability of the connection between the frame 300 and the mounting bracket 400, but also makes the connection between the frame 300 and the pressing device 100 more convenient.

[0051] In this embodiment, the height of the first support rib 120 can be set lower than that of the second support rib 130, or the height of the second support rib 130 can be set lower than that of the first support rib 120. However, regardless of which support rib is lower, during installation, the pressure block device 100 at the end corresponding to the support rib with the lower height and the corresponding side frame 300 are installed first; then the pressure block device 100 at the end corresponding to the support rib with the higher height and the corresponding side frame 300 are installed.

[0052] See Figure 1 and Figure 2 In one embodiment, the height of the first support rib 120 is lower than the height of the second support rib 130; the pressure block body 110 is connected to the mounting bracket 400, there is a gap between the first support rib 120 and the mounting bracket 400, and the second support rib 130 presses against the mounting bracket 400.

[0053] For ease of understanding, please refer to Figure 3 and Figure 4The description describes a configuration where the first support rib 120 is positioned lower than the second support rib 130. In this configuration, when installing the photovoltaic module 200, the frame 300 on the left side of the photovoltaic module 200 is first connected to the pressing device 100, and then the pressing device 100 is fixedly connected to the mounting bracket 400 using fasteners 150, such as bolts. Because the first support rib 120 is lower, the left end of the pressing device 100 can press the bottom of the frame 300 on the left side of the photovoltaic module 200 against the mounting bracket 400, thus making the connection between the frame 300 and the pressing device 100 more secure and stable. Finally, the mounting groove 310 of the frame 300 on the right side of the photovoltaic module 200 is aligned with the right end of the pressing device 100, and the photovoltaic module 200 is pushed towards the pressing device 100 so that the corresponding frame 300 engages with the pressing device 100. It is understandable that, due to the relatively high height of the second support rib 130, the space formed between the bottom right end of the pressure block body 110 and the mounting bracket 400 is relatively large, which makes it easier for the bottom of the frame 300 to be inserted between the pressure block body 110 and the mounting bracket 400.

[0054] See Figure 1 and Figure 2 In one embodiment, the snap-fit ​​structure 160 includes a top component 161 extending from the pressure block body 110 and a limiting protrusion 162 provided on the top component 161; the top component 161 can be displaced in the vertical direction, and the limiting protrusion 162 snaps into the photovoltaic module 200.

[0055] By configuring the top component 161 to extend beyond the top component 161, the top component 161 is suspended in the air, allowing it to move vertically and undergo elastic deformation. A limiting protrusion 162 is provided on the top component 161 to mutually abut and limit the movement of the top component 161 against the limiting protrusion 320 on the frame 300 of the photovoltaic module 200.

[0056] See Figure 1 and Figure 2 In one embodiment, the snap-fit ​​structure 160 and the support portion 140 are located on the same side of the pressure block body 110. Specifically, the top member 161 can rotate relative to the pressure block body 110 when subjected to external force, that is, it generates elastic deformation. The top member 161 extends along a first direction X. In some specific embodiments, the extension direction of the top member 161 can be the same as or opposite to that of the support portion 140. In one specific embodiment, the top member 161 and the support portion 140 are located on the same side of the same support plate 112.

[0057] See Figure 1 and Figure 2 In one embodiment, a limiting protrusion 162 is disposed in the middle of the top member 161 and protrudes in a direction away from the support portion 140. By providing a limiting protrusion 162 on the top member 161, and the limiting protrusion 162 protruding in a direction away from the support portion 140, when the frame 300 on the photovoltaic module 200 is connected to the pressing device 100, the deformation of the top member 161 causes the limiting protrusion 162 to pass over the limiting protrusion 320 on the frame 300 and enter the mounting groove 310 of the frame 300. When the top member 161 is no longer subject to the force of the limiting locking protrusion 320, the top member 161 returns to its original position, thereby causing the limiting protrusion 162 and the limiting locking protrusion 320 to mutually abut and limit each other, thereby achieving mutual limiting between the frame 300 and the pressing device 100, and making the connection between the frame 300 and the pressing device 100 more stable and reliable.

[0058] Understandably, to facilitate the installation of the pressing device 100 onto the frame 300 of the photovoltaic module 200, the top component 161 is designed to be elastically deformable. As a preferred embodiment, the top component 161 is made longer to improve its elastic deformation capability, thus making it easier for workers to install the pressing device 100 onto the frame 300. To allow the limiting protrusion 162 on the top component 161 to adapt to the limiting latching protrusion 320 on the frame 300, the limiting protrusion 162 can be positioned in the middle of the top component 161.

[0059] See Figure 1 and Figure 2 In one embodiment, a support portion 140 and a snap-fit ​​structure 160 are provided at each end of the pressing block body 110 along the first direction X. By providing a support portion 140 and a snap-fit ​​structure 160 at each end of the pressing block body 110 along the first direction X, the pressing block body 110 can be snap-fitted to the photovoltaic module 200 through the support portion 140 and snap-fit ​​structure 160 at both ends.

[0060] In some specific embodiments, the support portions 140 and the snap-fit ​​structures 160 at both ends of the pressing body 110 along the first direction X are symmetrically arranged. This arrangement ensures that the frame structures 300 on the two photovoltaic modules 200 connected to the pressing device 100 are identical, thereby facilitating the mass production and management of the frame structures 300, and also benefiting the installation of the pressing device 100 and the photovoltaic modules 200. Furthermore, the symmetrical arrangement simplifies the structure of the pressing device 100 and makes it easier to manufacture. In other embodiments, the support portions 140 and the snap-fit ​​structures 160 at both ends of the pressing body 110 can be configured as asymmetrical structures, allowing the pressing device 100 to adapt to frame structures 300 of different structures.

[0061] It can be understood that when the pressing block body 110 is only a structure with two oppositely arranged support plates 112 provided on both sides of the substrate 111, the pressing block body 110 is a U-shaped structure. In another embodiment, in order to improve the structural strength of the pressing block body 110, a reinforcing plate 113 is provided at the end of the support plate 112 facing away from the substrate 111, and both ends of the reinforcing plate 113 are respectively connected to the two support plates 112. In this way, the pressing block body 110 forms a structure similar to a "square" shape. This setting can improve the structural strength of the pressing block body 110, thereby preventing irreversible deformation of the pressing block device 100 caused by excessive load on the photovoltaic module 200. Specifically, the top member 161 can extend along the support plate 112 in the direction on the same side as the reinforcing plate 113, or can extend along the support plate 112 in the direction away from the reinforcing plate 113.

[0062] No specific limitation is imposed on the specific structure of the limiting protrusion 162. Hereinafter, the case where the top member 161 extends in the direction away from the reinforcing plate 113 will be taken as an example for description.

[0063] As Figure 1 and Figure 2 shown, in one embodiment, the surface of the end of the limiting protrusion 162 facing away from the support plate 112 is a guiding surface 1621, and the guiding surface 1621 forms an angle with the top member 161. Since when connecting the frame 300 of the photovoltaic module 200 to the pressing block device 100, the end face of the limiting protrusion 162 on the top member 161 facing away from the support plate 112 first contacts the limiting convex 320 on the frame 300, therefore, in order to facilitate the limiting protrusion 162 to cross over the limiting convex 320, this end face is configured as the guiding surface 1621 and the guiding surface 1621 is set as an inclined surface. Specifically, the distance between the guiding surface 1621 and the top member 161 gradually increases from the end away from the support plate 112 to the end close to the support plate 112, so as to guide when the limiting protrusion 162 crosses over the limiting convex 320 and enters the installation groove 310 through the inclination of the guiding surface 1621, thereby saving effort and facilitating the mutual clamping of the frame 300 and the pressing block device 100. Specifically, the guiding surface 1621 can be a flat surface or a curved surface with a certain curvature.

[0064] In one embodiment, the side surface of the end of the limiting protrusion 162 facing the support plate 112 is a resisting surface 1622; wherein, the resisting surface 1622 forms an angle with the top member 161.

[0065] The resisting surface 1622 is used for mutually resisting and limiting with the limiting convex 320 on the frame 300, thereby preventing the pressing block device 100 from disengaging from the installation groove 310. By setting the resisting surface 1622 to form an angle with the top member 161, it is convenient for the resisting surface 1622 to mutually resist and limit with the limiting convex 320 on the frame 300.

[0066] When the angle between the abutting surface 1622 and the top component 161 is acute, the cross-sectional structure of the limiting protrusion 162 formed by the abutting surface 1622 and the guide surface 1621 forms a hook-shaped structure. With this configuration, when one end of the pressing device 100 is installed into the mounting groove 310 of the frame 300, the limiting protrusion 162 on the pressing device 100 hooks with the limiting locking protrusion 320 on the mounting surface of the frame 300, thereby improving the mutual limiting performance of the limiting protrusion 162 and the limiting locking protrusion 320, thus preventing the pressing device 100 from detaching from the mounting groove 310, and ensuring the reliability of the connection between the pressing device 100 and the frame 300.

[0067] Specifically, there is no restriction on the type of angle between the abutting surface 1622 and the top component 161; it can be any one of an acute angle, a right angle, or an obtuse angle. When the angle between the abutting surface 1622 and the top component 161 is a right angle, the cross-sectional structure of the limiting protrusion 162 formed by the abutting surface 1622 and the guide surface 1621 is a right-angled triangle. With this configuration, when one end of the pressing device 100 is installed into the mounting groove 310, the abutting surface 1622 of the limiting protrusion 162 on the pressing device 100 abuts against the side surface of the limiting latching protrusion 320, thereby ensuring the mutual limiting performance of the limiting protrusion 162 and the limiting latching protrusion 320, preventing the pressing device 100 from detaching from the mounting groove 310, and thus ensuring the reliability of the connection between the pressing device 100 and the frame 300.

[0068] In another embodiment, the abutment surface 1622 can be configured to form an obtuse angle with the top component 161, so that the cross-sectional structure of the limiting protrusion 162 formed between the abutment surface 1622, the guide surface 1621, and the top component 161 is an obtuse triangle. This configuration ensures the reliability of the limiting protrusion 320 on the frame 300 in limiting the limiting protrusion 162 on the pressing device 100, while facilitating the removal of the pressing device 100 from the mounting groove 310.

[0069] It is understandable that the limiting protrusion 162 extends continuously along the length of the top component 161. This ensures the structural strength of the limiting protrusion 162.

[0070] like Figure 2 As shown, in one embodiment, the pressing device 100 further includes a fastener 150. The pressing body 110 has a connecting hole, and the mounting bracket 400 has a mounting hole. The fastener 150 passes through the connecting hole and is fastened to the mounting hole.

[0071] Specifically, the fastener 150 is a bolt. The bolt is fixedly connected to the mounting bracket 400 by passing it through the mounting hole on the pressure block body 110. This achieves a fixed connection between the pressure block device 100 and the mounting bracket 400. Furthermore, the bolt is a standard component, simple in structure, and readily available.

[0072] In one embodiment, the pressing body 110, the snap-fit ​​structure 160, and the support portion 140 are integrally formed. Specifically, the pressing body 110, the snap-fit ​​structure 160, and the support portion 140 are integrally formed by extrusion molding. This simplifies the molding process of the pressing device 100 while improving the overall structural strength of the pressing device 100.

[0073] like Figure 3 and Figure 4 The present invention also provides a photovoltaic system 1000, which includes the pressing device 100 as described above. The photovoltaic system 1000 also includes a photovoltaic module 200 and a frame 300. The frame 300 is connected to the four edges of the photovoltaic module 200 and has a mounting groove 310. The snap-fit ​​structure 160 snaps into the groove wall of the mounting groove 310, and the support part 140 abuts against another groove wall of the mounting groove 310.

[0074] By applying the above-mentioned pressing device 100 to the photovoltaic system 1000, the contact area between the pressing device 100 and the frame 300 on the photovoltaic module 200 can be increased through the surface contact between the support part 140 and the photovoltaic module 200, thereby making the connection between the pressing device 100 and the photovoltaic module 200 more stable and reliable. In addition, by abutting the support part 140 against the frame 300 of the photovoltaic module 200, the groove depth of the mounting groove 310 of the frame 300 is increased, thereby accommodating the elastic deformation of the mounting body, so that the top part 161 can be engaged with the frame 300 to a greater extent, thereby improving the reliability and stability of the connection between the pressing device 100 and the photovoltaic module 200.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
