Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic panel installation, and particularly relates to a photovoltaic bracket. Background Art

[0002] In recent years, the installation and construction of photovoltaic power stations are characterized by large scale, high proportion and high cost. Steel structure workshops generally have large spans and occupy a large area, which are more suitable for the installation of photovoltaic panels. Therefore, more and more photovoltaic power stations are being built on steel structure roofs. In traditional practice, photovoltaic panels built on steel structure roofs are usually installed with fixed brackets on the roof panels first, and then the guide rails for laying photovoltaic panels are installed on the fixed brackets in sequence, and finally the photovoltaic panels are laid on the guide rails. This method not only consumes a large amount of raw materials for the guide rails, but also increases the load on the roof panels. It is also inconvenient to install, and the construction progress of the photovoltaic panels is affected by the progress of the bracket installation.

[0003] To this end, the Chinese utility model patent with application number CN202321707611.0 discloses a photovoltaic connection structure suitable for a standing seam roof, including multiple crest structures, multiple photovoltaic panels, a main pressure block and multiple top pressure blocks. When in use, the main pressure block is first clamped to the crest structure, and then the top pressure block is fixed with bolts. The photovoltaic panel is fixed by cooperating between the horizontal limbs of the top pressure block and the top edge of the crest structure.

[0004] For another example, the Chinese invention patent with application number 201980032371.9 discloses a PV module mounting assembly with a clamp / support device, which proposes a variety of mounting assemblies that can be applied to photovoltaic panel installation, and the mounting assembly may include a clamp fixed to a column by a clamping fastener. The mounting assembly may also include a mounting plate, which may be fixed to the mounting device by a column. The mounting assembly can be used, for example, to fix photovoltaic modules (or other devices or structures) of different heights to a roof or other building surface.

[0005] However, the above solutions have at least the following problems:

[0006] 1. The installation flexibility of photovoltaic panels needs to be improved;

[0007] 2. There are many parts, the structure is complex, and the installation process is cumbersome.

[0008] Therefore, there is an urgent need for a photovoltaic bracket that is easy to install and has high flexibility. Summary of the invention

[0009] The purpose of the present invention is to provide a photovoltaic bracket suitable for seamless installation of batch photovoltaic panels, so as to partially alleviate or solve the above-mentioned problems, and to improve the flexibility and convenience of photovoltaic panel installation while ensuring installation stability.

[0010] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: a photovoltaic bracket, comprising a mounting seat, a fixing member and a rectangular mounting plate arranged in sequence from bottom to top, wherein the bottom of the mounting seat is provided with a mounting groove for matching with the vertical seam of the roof, and the top and the first side wall of the mounting seat are respectively provided with a first threaded hole and at least one second threaded hole;

[0011] A mounting hole is provided at the center of the mounting plate, and at least two buckles are symmetrically provided on the second surface of the mounting plate; the mounting plate protrudes upward from the mounting hole to both sides in sequence to form two limiting protrusions, is recessed downward to form two first limiting edges, and is bent upward again to form two second limiting edges, the limiting protrusions and the second limiting edges located on the same side of the mounting hole cooperate to form a limiting path for limiting the photovoltaic panel connector, the extending direction of the limiting path is perpendicular to the plane where the roof vertical seam is located, and the two first limiting edges cooperate with the buckles to form a clamping structure for circumferentially clamping the mounting seat;

[0012] A light hole is provided at the center of the fixing member, and at least one side edge of the fixing member extends outward and is bent to form a clamping edge; when the fixing member is fixed to the mounting plate and the mounting seat using a long bolt, the clamping edge cooperates with the limiting path to limit the photovoltaic panel connector in the height direction;

[0013] The portion of the screw rod of the long bolt close to the bolt head is a smooth screw rod, and the end of the screw rod away from the bolt head is a threaded rod.

[0014] As an improvement, a positioning sleeve is fixedly provided on the first surface of the mounting plate, and a through hole of the positioning sleeve is connected to the mounting hole; correspondingly, two side edges of the fixing member respectively extend downward to form positioning grooves that cooperate with the positioning sleeve.

[0015] As an improvement, the mounting hole and the through hole of the positioning sleeve are both smooth, and the diameter of the mounting hole and the diameter of the through hole are both larger than the maximum diameter of the screw rod; during installation, when the long bolt is screwed into the first threaded hole and rotated to the maximum limit, the bolt head of the long bolt abuts against the top of the fixing member.

[0016] As an improvement, the distance between the two buckles is the same as the width of the mounting seat, the distance between the two first limiting edges is the same as the length of the mounting seat, and the buckle is an elastic buckle; when the buckle is placed against the side wall of the mounting seat and pressed downward, the distance between the two buckles becomes larger, and when pressed into place, the two buckles are reset and clamped on the mounting seat.

[0017] As an improvement, the limiting protrusion, the first limiting edge and the second limiting edge are all arranged in the length direction of the mounting plate, and correspondingly, the line connecting the center points of the two buckles is parallel to the extension line of the length direction of the mounting plate.

[0018] As an improvement, a first groove is formed between the two limiting protrusions, and the mounting hole is located in the first groove; a second groove is formed between the first limiting edge and the second limiting edge located on the same side of the mounting hole.

[0019] As an improvement, a plurality of cable through holes are circumferentially arranged on the edge of the mounting plate, and the plurality of cable through holes are respectively located in the first groove and the second groove.

[0020] As an improvement, two second threaded holes are provided, and the two second threaded holes are evenly distributed on the first side wall of the mounting seat.

[0021] As an improvement, at least one recessed portion cooperating with a headless bolt is provided on the inner wall of the second side wall of the installation groove; when the roof upright seam is installed inside the installation groove, the headless bolt is installed into the second threaded hole, so that the contact portion between the roof upright seam and the headless bolt is pressed into the recessed portion, and a clamping structure for clamping the roof upright seam is formed between the second side wall of the installation groove and the headless bolt.

[0022] As an improvement, the first surface of the mounting plate is provided with at least one tooth-shaped protrusion.

[0023] The principles and beneficial effects of the present invention are:

[0024] The present application provides a mounting plate with multiple limiting structures, and cooperates with the mounting plate and the fixing parts to form more limiting structures, thereby comprehensively providing a photovoltaic bracket with multiple limiting structures, which can ensure the installation stability of the photovoltaic panels while flexibly adjusting the position of the photovoltaic panels.

[0025] Specifically, a circumferential clamping structure is first formed by the buckle and the two first limiting edges, so that the mounting plate can be stably clamped on the mounting seat by means of a snap connection, which is easy to install and can effectively prevent the mounting plate from rotating in the horizontal direction.

[0026] Furthermore, when the photovoltaic panel connector is installed in the limiting path formed between the second limiting edge and the limiting protrusion, firstly, the second limiting edge and the limiting protrusion can limit the photovoltaic panel connector in the width direction, and secondly, the mounting plate cooperates with the clamping edge of the fixing member to limit the photovoltaic panel connector in the height direction, that is, a limiting space is formed between the mounting plate and the fixing member; after the photovoltaic panel is installed, it can slide back and forth in the limiting path without leaving the limiting space, thereby achieving flexible and stable adjustment.

[0027] The prior art (the U.S. invention patent with publication number US2024014770A1) discloses a photovoltaic bracket, which is provided with a disc-shaped mounting plate. On the one hand, the disc-shaped mounting plate cannot limit the direction of the photovoltaic panel when the photovoltaic panel is installed, that is, the photovoltaic panel can swing freely forward, backward, left and right along the circumference of the disc, which will cause the photovoltaic panels to be unable to be aligned and tightly connected, and also increase the difficulty of installation; in addition, the scheme also sets a substrate between the mounting plate and the mounting device, and there is a gap between the photovoltaic panel and the flange on the side of the substrate to limit the movable range of the photovoltaic panel, that is, the flange of the substrate cannot cooperate with the mounting plate to clamp and fix the photovoltaic panel, and the toothed structure of the inner wall of the flange also makes it impossible for the photovoltaic panel to move back and forth easily on the mounting plate, and the installation of the substrate will affect some functions of the mounting plate: for example, the spikes of the disc and the structure at the bottom of the disc cannot play any role; when installing photovoltaic panels over a large area, it is best to ensure that there is no gap between the photovoltaic panels, so as to improve resource utilization. The structure in the above scheme is not suitable for seamless installation of batch photovoltaic panels.

[0028] As mentioned above, the clamping structure in the present invention cooperates with the limiting path, so that multiple photovoltaic panels can always move stably along the length direction of the limiting path, so that the photovoltaic panels can be aligned and tightly connected to form a whole large photovoltaic panel, thereby improving space utilization and reducing installation difficulty. At the same time, when the photovoltaic panel slides in the limiting path, the force exerted on the mounting plate is always perpendicular to the vertical seam of the roof, which can prevent the mounting base from sliding on the vertical seam of the roof due to force.

[0029] In summary, the present application uses multiple limiting structures and clever directional design between the limiting structures to enable the photovoltaic panels to be stably and flexibly adjusted on the bracket, thereby allowing the photovoltaic panels to be seamlessly spliced ​​together to form a whole large photovoltaic panel.

[0056] Herein "and / or" includes any and all combinations of one or more of the associated listed items.

[0057] Herein, "plurality" means two or more than two, ie, it includes two, three, four, five, etc.

[0058] This embodiment is basically Figure 1-Figure 20 As shown:

[0059] like Figure 1 The present invention provides a photovoltaic bracket, comprising a mounting seat 1, a mounting plate 2 and a fixing member 3 which are arranged in sequence from bottom to top.

[0060] In some embodiments, the mounting base and the fixing member are both made of aluminum alloy.

[0061] Among them, see Fig.10 The bottom of the mounting seat is provided with a mounting groove for cooperating with the vertical seam of the roof, and the top and the first side wall (one of the side walls can be any one of the two side walls) of the mounting seat are respectively provided with a first threaded hole 101 and at least one second threaded hole 102. Exemplarily, the cross section of the mounting seat is similar to the shape of "π";

[0062] like Figure 11-13, a mounting hole 201 is provided at the center position of the mounting plate 2, a positioning sleeve is provided on the first surface of the mounting plate 2 (the side not in contact with the mounting seat), the through hole of the positioning sleeve is connected to the mounting hole, and at least two buckles 202 are symmetrically provided on the second surface of the mounting plate; the mounting plate 2 protrudes upward from the mounting hole 201 to both sides to form two limiting protrusions 203, is recessed downward to form two first limiting edges 204, and is bent upward again to form two second limiting edges 205, the limiting protrusions 203 and the second limiting edges 205 located on the same side of the mounting hole cooperate to form a limiting path for limiting the photovoltaic panel connector, the extending direction of the limiting path is perpendicular to the plane where the roof vertical seam is located, and the two first limiting edges 204 cooperate with the buckles 202 to form a clamping structure for circumferentially clamping the mounting seat;

[0063] The second limiting edge is formed by rolling up the edge of the mounting plate, and the angle between the second limiting edge and the plane where the mounting plate is located is 90°-100° (preferably 90°).

[0064] In some embodiments, since the positioning sleeve only needs to play a guiding and positioning role during installation, the fixing strength between the positioning sleeve and the mounting plate does not need to be very large, so the positioning sleeve can be welded to the first surface of the mounting plate by spot welding.

[0065] Exemplarily, the mounting plate may be rectangular in shape as a whole. Accordingly, the length direction in this article refers to the length extension direction of the mounting plate, and the width direction refers to the width extension direction of the mounting plate; the horizontal direction refers to the direction parallel to the plane where the mounting plate is located, and the vertical direction refers to the direction perpendicular to the plane where the mounting plate is located.

[0066] When the buckle is clamped on two opposite sides of the mounting seat (for example, two side edges in the width direction), and the two first limiting edges are pressed against the other two sides of the mounting seat (for example, two side edges in the length direction), the mounting plate and the mounting seat are relatively fixed, and the mounting hole and the first threaded hole are coaxial;

[0067] Through the above structure, the mounting plate can be fixed on the mounting seat by its own structure without the need for other auxiliary fixing structures (such as bolts and nuts), and the buckle and the first limiting edge cooperate to be circumferentially clamped on the four sides of the mounting seat, which can effectively prevent the mounting plate and the mounting seat from rotating relative to each other. After the two are relatively fixed, it is also convenient to install other components on the mounting plate.

[0068] When the photovoltaic panel connector is inserted into the limiting path formed between the limiting protrusion and the second limiting edge, the limiting protrusion and the second limiting edge can limit the bottom of the photovoltaic panel connector in the width direction, and the photovoltaic panel connector can slide along the length direction within the limiting path.

[0069] Furthermore, when installing the fixing, the positioning groove is directly stuck on the outside of the positioning sleeve, so the installation position of the fixing can be quickly determined. In addition, the positioning sleeve can preliminarily locate the installation positions of the first threaded hole, the mounting hole and the light hole. At the same time, the positioning sleeve can guide the installation direction of the long bolt, further simplifying the installation process.

[0070] like Figure 14-16 A light hole 301 is provided at the center position of the fixing member 3, and the two side edges of the fixing member 3 respectively extend downward to form a positioning groove 302 that cooperates with the positioning sleeve, and at least one side edge extends outward and bends to form a clamping edge 303; when the fixing member is fixed to the mounting plate and the mounting seat using long bolts, the clamping edge cooperates with the limiting path to limit the photovoltaic panel connector in the height direction.

[0071] Specifically, Fig.14 and Fig.15 A fixing member is shown, and both sides of the fixing member are provided with pressing edges, so that photovoltaic panels can be installed on both sides of the fixing member; Fig.16 Another fixing member is shown, in which only one side of the fixing member is provided with a clamping edge. The fixing member is suitable for situations where only one photovoltaic panel needs to be installed thereon, such as the installation of a photovoltaic panel at the edge of a roof.

[0072] During specific installation, first, the mounting groove at the bottom of the mounting base is clamped on the vertical joint of the roof, at this time the two can move relatively, then screw the bolt (preferably a headless bolt) into the second threaded hole, and the screwed-in end of the bolt is against the side wall of the vertical joint of the roof, so as to achieve the fixation of the two, and then the buckle and the first limiting edge of the mounting plate are respectively against or clamped on the four side edges of the mounting base for fixation, at this time the first threaded hole and the mounting hole correspond, and then the photovoltaic panel mounting piece is clamped into the limiting path for pre-fixation, and then the positioning groove of the fixing piece is clamped on the positioning sleeve, so that at least the upper half of the positioning sleeve is located in the positioning groove, and the light hole is aligned with the through hole of the positioning sleeve, and the fixing piece is pressed downward so that the pressing edge of the fixing piece is fitted on the upper surface of the photovoltaic panel connector, and finally the long bolt is passed through the light hole, the through hole and the mounting hole in turn, and screwed into the first threaded hole to achieve the locking of all the above structures. The structure after the installation is completed can be seen in Figure 1 and Figure 2 .

[0073] In some embodiments, Figure 3The clamping edge is arc-shaped. Specifically, at least one side edge of the fixing member first extends outward in the horizontal direction to form a horizontal portion 3031, and then extends obliquely downward to form a bending portion 3032. The horizontal portion 3031 cooperates with the mounting plate to limit the photovoltaic panel connector in the vertical direction (also referred to as the height direction in this article). The bending portion 3032 cooperates with the side wall of the fixing member to limit the photovoltaic panel connector in the horizontal direction. Thus, the photovoltaic panel connector can be limited at multiple angles, making the photovoltaic panel installation more stable.

[0074] In some embodiments, the portion of the screw rod of the long bolt close to the bolt head is a smooth screw rod, and correspondingly, the mounting hole and the through hole of the positioning sleeve are both smooth, and the diameter of the mounting hole and the diameter of the through hole are both larger than the maximum diameter of the screw rod; during installation, when the long bolt is screwed into the first threaded hole and rotated to the maximum limit, the bolt head of the long bolt rests against the top of the fixing member.

[0075] Through the design of the above structure, the long bolt encounters little or almost no resistance when extending into the light hole, the through hole and the mounting hole, and force is only required when the long bolt is screwed into the first threaded hole, which can greatly reduce the installation workload.

[0076] In some embodiments, the distance between the two buckles is the same as the width of the mounting seat, and the distance between the two first limiting edges is the same as the length of the mounting seat.

[0077] In some embodiments, the buckle is an elastic buckle; when the mounting plate is pressed downward, the buckle on the mounting plate is stretched open, so that the mounting seat is smoothly inserted into the clamping structure, and after being installed in place, the buckle automatically resets and clamps on both sides of the mounting seat. In this process, the clamping structure space enclosed by the buckle and the first limiting edge changes from small to large and then to small, which can make installation easier.

[0078] In some embodiments, the limiting protrusion, the first limiting edge and the second limiting edge are all arranged in the length direction of the mounting plate, and correspondingly, the line connecting the center points of the two buckles is parallel to the extension line of the length direction of the mounting plate.

[0079] In some embodiments, a first groove is formed between two limiting protrusions, and the mounting hole is located in the first groove; a second groove is formed between a first limiting edge and a second limiting edge located on the same side of the mounting hole, and the mounting hole is located in the first groove, and the buckle is arranged between the first groove and the second groove.

[0080] In some embodiments, a plurality of cable through holes are circumferentially arranged at an edge of the mounting plate, and the plurality of cable through holes are respectively located in the first groove and the second groove.

[0081] In some embodiments, two second threaded holes are provided, and the two second threaded holes are evenly distributed on the first side wall of the mounting base.

[0082] In some embodiments, at least one recessed portion cooperating with the headless bolt is provided on the inner wall of the second side wall of the mounting slot;

[0083] When the roof vertical seam is installed inside the installation groove and the headless bolt is installed into the second threaded hole, the contact portion between the roof vertical seam and the headless bolt is pressed into the recessed portion, and a clamping structure for clamping the roof vertical seam is formed between the second side wall of the installation groove and the headless bolt.

[0084] When the present solution uses headless bolts for fixing, the screw-in length of the headless bolts can be freely adjusted within the length range of the headless bolts without being restricted by the bolt heads, thereby adapting to the distance between the roof standing seams and the inner wall of the mounting base.

[0085] In some embodiments, see Fig.13 The first surface of the mounting plate is provided with at least one tooth-shaped protrusion 209 for piercing the oxide film or other coating on the surface of the photovoltaic panel connector.

[0086] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0087] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
