Description
Technical Field
[0001] This utility model relates to the field of photovoltaic panel installation equipment technology, and in particular to a connector for photovoltaic panel installation. Background Technology
[0002] A photovoltaic panel, also known as a solar photovoltaic panel, is a core device that converts solar energy into electrical energy. It consists of photovoltaic cells, glass, a backsheet, and a frame. Through the photoelectric effect, it absorbs photons from sunlight, causing electrons in the cells to transition and generate an electric current, thus providing clean energy to the power grid.
[0003] Photovoltaic panel mounting connectors securely assemble dispersed photovoltaic panels into an array, ensuring a fixed angle and position in rooftop and ground-based applications, resisting external forces, guaranteeing smooth electrical connections between panels, and enabling efficient transmission of generated electricity.
[0004] During the installation of photovoltaic panels, if the photovoltaic panels are placed directly on the frame using bolts, the lack of a stable connection structure means that the photovoltaic panels will shift due to external forces and wind, making it impossible to maintain a stable installation posture. In existing technologies, connectors are used to connect the photovoltaic panels and the frame. The connectors establish a connection between the photovoltaic panels and the frame, fixing the photovoltaic panels to the frame through their own structure and limiting the displacement of the photovoltaic panels, effectively solving the problem of the photovoltaic panels collapsing when placed directly on the frame. However, in actual use, the right-angle structure of traditional connectors causes the stress to concentrate at the corners when external forces are applied. As the concentrated stress accumulates, it exceeds the bearing limit of the connector material, causing cracks to appear at the corners of the connectors and leading to connector breakage. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a connector for photovoltaic panel installation, aiming to improve the problem that the right-angle structure of traditional connectors in the prior art causes stress to concentrate at the corner when external forces are applied. The concentrated stress accumulates continuously and, after exceeding the bearing limit of the connector material, will cause cracks to appear at the corner of the connector, leading to the connector breakage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connector for photovoltaic panel installation, comprising an intermediate plate, wherein a connecting mechanism is provided at the top of the intermediate plate for fixed splicing with the photovoltaic panel, and a fixing mechanism is provided at the bottom of the intermediate plate for fixing a load-bearing cable; The connecting mechanism includes two side plates, the bottom of which is located at the top of the middle plate. Two circular holes are formed at the bottom of the two side plates. Bolts are threaded through the top left and right sides of the middle plate. Nuts are threaded to the bottom of the two bolts. The connecting mechanism also includes a single side plate, the bottom of which is located at the top of the middle plate. Two circular holes are formed on the inner side of the single side plate.
[0007] As a further description of the above technical solution: The fixing mechanism includes two bolts, the bottom of which penetrates the top of the intermediate plate, and the bottom of each bolt is threaded with a nut. A clamp is fixedly connected to the bottom of the intermediate plate, and the top of the clamp has two round holes.
[0008] As a further description of the above technical solution: The middle plate, double-sided plates, and single-sided plates are all made of Q235B steel, and the surfaces of the middle plate, double-sided plates, and single-sided plates are all galvanized.
[0009] As a further description of the above technical solution: The middle section of the middle plate adopts an inverted U-shaped protrusion structure, the top of the middle plate adopts a rounded rectangular structure, and the corners of the middle plate are all designed with rounded corners.
[0010] As a further description of the above technical solution: The double side panels adopt a U-shaped structure, and the corners of the double side panels are rounded.
[0011] As a further description of the above technical solution: The left and right sides of the single-sided panel are folded in opposite directions, and the corners of the single-sided panel are rounded.
[0012] As a further description of the above technical solution: The surfaces of both bolts (bolt 1 and bolt 2) are galvanized, and the tops of both bolts (bolt 1 and bolt 2) are provided with hexagonal grooves.
[0013] As a further description of the above technical solution: The top of the intermediate plate has two circular holes, and the top left and right sides of the intermediate plate have elongated holes. The front and back sides of the two elongated holes are both arc-shaped.
[0014] This utility model has the following beneficial effects: 1. In this utility model, double-sided plates are used to insert the mounting edges of photovoltaic panels on both sides, and single-sided plates are attached to the mounting edges of photovoltaic panels on one side. Bolts pass through the mounting holes of photovoltaic panels, the holes of side plates and the long holes of the middle plate, and are fixed by tightening nuts. The inverted U-shaped protrusion of the middle plate enhances the strength, and all corners are rounded to achieve a stable splicing of the photovoltaic panels on both sides and one side, prevent stress concentration cracking at corners, and enhance the structural support stability.
[0015] 2. In this utility model, the bolts of the fixing mechanism pass through the round holes of the middle plate, the side plate, and the clamp, and the nuts at the bottom are tightened to fix the multi-layer board. When fixing the photovoltaic panel, the bolts pass through the mounting holes of the middle plate and the photovoltaic panel, and the nuts are tightened by the hexagonal groove.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Reference Figures 1-5 The present invention provides an embodiment of a connector for photovoltaic panel installation, comprising a middle plate 1, the middle part of which adopts an inverted U-shaped protrusion structure, the top of which adopts a rounded rectangular structure, and the corners of the middle plate 1 are all designed with rounded corners. A connecting mechanism 2 is provided on the top of the middle plate 1 for fixing and splicing with the photovoltaic panel, and a fixing mechanism 3 is provided on the bottom of the middle plate 1 for fixing the load-bearing cable. The connecting mechanism 2 includes double side plates 21, which adopt a U-shaped structure. The corners of the double side plates 21 are rounded. The bottom of the double side plates 21 is set on the top of the middle plate 1. Two round holes 22 are opened at the bottom of the double side plates 21. Bolts 25 pass through the top left and right sides of the middle plate 1. Nuts 26 are threaded to the bottom of the two bolts 25. The middle plate 1 and the double side plates 21 are both made of Q235B steel. The surfaces of the middle plate 1 and the double side plates 21 are galvanized. Specifically, the intermediate plate 1 is the basic support structure, the connecting mechanism 2 realizes the fixed splicing with the photovoltaic panel, and the fixing mechanism 3 fixes the load-bearing cable, which together provide connection and support for the installation of the photovoltaic panel; The connectors cooperate with the connecting mechanism 2 and the intermediate plate 1 to fix and splice the photovoltaic panels. The double-sided plates 21 of the connecting mechanism 2 adopt a U-shaped structure, with their bottoms set on the top of the intermediate plate 1. Two round holes 22 are opened at the bottom of the double-sided plates 21. Bolts 25 are passed through the left and right sides of the top of the intermediate plate 1. When fixing with the photovoltaic panel, the mounting edge of the photovoltaic panel is placed on the left and right sides of the double-sided plates 21, so that the mounting hole of the photovoltaic panel is aligned with the long hole 5 of the intermediate plate 1. Then, the bolts 25 are passed through the edge of the photovoltaic panel, and then through the long hole 5 at the top of the intermediate plate 1. Nuts 26 are threaded to the bottom of the bolts 25. The nuts 26 are tightened to make the double-sided plates 21 fit with the photovoltaic panel. The intermediate plate 1 provides support for the double-sided plates 21 through the cooperation of the bolts 25 and nuts 26, restricting the displacement of the photovoltaic panel within the double-sided plates 21, and realizing the fixed splicing of the photovoltaic panels. The connector ensures support stability through the structural design of the intermediate plate 1. The middle part of the intermediate plate 1 adopts an inverted U-shaped protrusion structure, the top adopts a rounded rectangle structure, and the corners are all rounded. The inverted U-shaped protrusion structure can enhance the structural strength of the intermediate plate 1 itself and prevent the intermediate plate 1 from deforming when bearing the weight of the photovoltaic panel. The rounded rectangle structure at the top is adapted to the bottom of the double side plates 21 to ensure that the double side plates 21 are stably placed on the top of the intermediate plate 1. The rounded corner design at the corners reduces the risk of scratches on the intermediate plate 1 during installation and use, and at the same time avoids stress concentration that could cause cracks at the corners of the intermediate plate 1, thus achieving structural support and safety assurance for the intermediate plate 1. Both the intermediate plate 1 and the double-sided plates 21 are made of Q235B steel and have a galvanized surface. The corners of the double-sided plates 21 are rounded. Q235B steel has good mechanical properties and can withstand the weight transmitted by the photovoltaic panel and external loads, avoiding damage due to insufficient material strength. The galvanized surface treatment forms a protective layer on the surface of the intermediate plate 1 and the double-sided plates 21, isolating air and moisture from contact with the surface, preventing the components from rusting and corroding, and extending the service life of the components. The rounded corners of the double-sided plates 21 improve the safety of use and avoid damage to the photovoltaic panel caused by sharp corners, thus ensuring the durability and safety of the connectors.
[0019] Reference Figures 3-5 Another embodiment of this utility model provides: a connector for photovoltaic panel installation, including a middle plate 1, the middle part of the middle plate 1 adopts an inverted U-shaped protrusion structure, the top of the middle plate 1 adopts a rounded rectangular structure, the corners of the middle plate 1 are all designed with rounded corners, the top of the middle plate 1 is provided with a connecting mechanism 2, the connecting mechanism 2 is used for fixed splicing with the photovoltaic panel, and the bottom of the middle plate 1 is provided with a fixing mechanism 3, the fixing mechanism 3 is used for fixing the load-bearing cable; The connecting mechanism 2 includes a single-side plate 23, the left and right sides of the single-side plate 23 are folded in opposite directions, the corners of the single-side plate 23 are rounded, the bottom of the single-side plate 23 is set on the top of the middle plate 1, two round holes 24 are opened on the inner side of the single-side plate 23, and bolts 25 are passed through the top left and right sides of the middle plate 1, and nuts 26 are threaded to the bottom of the two bolts 25. The middle plate 1 and the single-side plate 23 are both made of Q235B steel, and the surfaces of the middle plate 1 and the single-side plate 23 are galvanized. Specifically, the intermediate plate 1 is the basic support structure, the connecting mechanism 2 realizes the fixed splicing with the photovoltaic panel, and the fixing mechanism 3 fixes the load-bearing cable, which together provide connection support for the installation of the photovoltaic panel; The photovoltaic panels are fixedly spliced by the connecting mechanism 2 in cooperation with the intermediate plate 1. The left and right sides of the single-side plate 23 of the connecting mechanism 2 are folded in opposite directions, and the corners are rounded. Its bottom is set on the top of the intermediate plate 1, and the left side of the single-side plate 23 is attached to the top left side of the intermediate plate 1. Two round holes 24 are opened on the inner side of the single-side plate 23. Bolts 25 pass through the top left and right sides of the intermediate plate 1. When fixing with the photovoltaic panel, the mounting edge of the photovoltaic panel is attached to the right side of the single-side plate 23, so that the mounting hole of the photovoltaic panel is aligned with the elongated hole 5 of the intermediate plate 1. Then... Bolt 25 passes through the photovoltaic panel mounting hole, through the round hole 24 of the single-side plate 23 and the photovoltaic panel mounting hole, and then through the long hole 5 on the top right side of the middle plate 1. Nut 26 is threaded to the bottom of bolt 25. Tightening nut 26 makes the single-side plate 23 fit tightly with the photovoltaic panel. The reverse folding structure of the single-side plate 23 forms a limit on the photovoltaic panel mounting edge. The middle plate 1 provides support for the single-side plate 23 through the cooperation of bolt 25 and nut 26, restricting the displacement of the photovoltaic panel inside the single-side plate 23, and realizing the fixed splicing of the photovoltaic panel. The connector ensures support stability through the structural design of the intermediate plate 1. The middle part of the intermediate plate 1 adopts an inverted U-shaped protrusion structure, and the top adopts a rounded rectangle structure. The corners are all rounded. The inverted U-shaped protrusion structure can enhance the structural strength of the intermediate plate 1 itself and prevent the intermediate plate 1 from deforming when bearing the weight of the photovoltaic panel. The rounded rectangle structure at the top is adapted to the bottom of the single-side plate 23, ensuring that the single-side plate 23 is stably placed on the top of the intermediate plate 1 and preventing the single-side plate 23 from shifting after installation. The rounded corner design at the corners reduces the risk of scratches on the intermediate plate 1 during installation and use, and at the same time avoids stress concentration that could cause cracks at the corners of the intermediate plate 1, thus achieving structural support and safety assurance for the intermediate plate 1. The connectors are made of Q235B steel with galvanized finish. The corners of the single-side plate 23 are rounded. Q235B steel has good mechanical properties and can withstand the weight transmitted by the photovoltaic panel and external loads, preventing damage to components due to insufficient material strength. The galvanized finish forms a protective layer on the surfaces of the intermediate plate 1 and the single-side plate 23, isolating air and moisture from contact with the surface, preventing rust and corrosion, and extending the service life of the components. The rounded corners of the single-side plate 23 further improve safety and prevent damage to the photovoltaic panel from sharp corners, thus ensuring the durability and safety of the connectors.
[0020] Reference Figures 1-6The fixing mechanism 3 includes two bolts 21, two bolts 1 25 and two bolts 2 31 are galvanized, the top of the two bolts 1 25 and two bolts 2 31 are provided with hexagonal groove structure, the bottom of the two bolts 2 31 penetrates the top of the intermediate plate 1, the bottom of the two bolts 2 31 is threaded with nuts 2 32, the bottom of the intermediate plate 1 is fixedly connected with a clamp 33, the top of the clamp 33 is provided with two round holes 34, the top of the intermediate plate 1 is provided with two round holes 4, the top of the intermediate plate 1 is provided with elongated holes 5 on the left and right sides, and the front and rear sides of the two elongated holes 5 are both provided with arc structure; Specifically, the middle plate 1 and the double-sided plates 21 or single-sided plates 23 are fixed by bolts 21 and nuts 22 of the fixing mechanism 3. The bottom of the two bolts 21 penetrates the round hole 4 at the top of the middle plate 1 and the round hole 1 22 at the top of the double-sided plate 21 or the round hole 24 at the top of the single-sided plate 23, and then penetrates the round hole 34 of the clamp 33, thus achieving simultaneous fixing of the multi-layer plates. Nuts 22 are threaded to the bottom of each bolt. The surfaces of the two bolts 1 25 and the two bolts 21 are galvanized, and the tops are provided with hexagonal groove structures. When fixing the intermediate plate 1 and the photovoltaic panel, align the mounting holes of the photovoltaic panel with the four round holes 4 on the top of the intermediate plate 1. Insert the bolt 2 31 through the top of the intermediate plate 1 and through the mounting holes of the photovoltaic panel. Thread the nut 2 32 to the bottom of the bolt 2 31. Use a tool to tighten the nut 2 32 with the help of the hexagonal groove structure to make the photovoltaic panel fit with the intermediate plate 1. Galvanizing prevents the bolt 2 31 and the nut 2 32 from rusting. The hexagonal groove structure facilitates tool operation and restricts the relative displacement between the photovoltaic panel and the intermediate plate 1, thus achieving a stable fixation between the intermediate plate 1 and the photovoltaic panel. The connector fixes the load-bearing cable through the clamp 33 of the fixing mechanism 3. The top of the clamp 33 is fixedly connected to the bottom of the intermediate plate 1. Two round holes 34 are opened on the top. When fixing the load-bearing cable, the load-bearing cable is placed inside the clamp 33. The position of the load-bearing cable is adjusted so that it is in the center area of the clamp 33. Then, the bolt 2 31 is passed through the round holes 34 of the clamp 33 to tighten the open end of the clamp 33, so that the inner wall of the clamp 33 contacts the load-bearing cable. The arc structure of the clamp 33 is adapted to the shape of the load-bearing cable, increasing the contact area with the load-bearing cable and preventing the load-bearing cable from sliding inside the clamp 33, so as to achieve a stable fixation of the load-bearing cable and provide load-bearing support for the installation of photovoltaic panels. The connector is installed and adapted through the four round holes 4 and the long holes 5 in the middle plate 1. The top of the middle plate 1 has two round holes 4, and the left and right sides have long holes 5. The front and back sides of the two long holes 5 are arc-shaped. The round holes 4 provide a through channel for the bolt 25 to ensure the installation of the bolt 31. When it is necessary to adjust the installation position of the connector and the photovoltaic panel, the external connector can move along the length of the long hole 5 to adapt to different installation spacing requirements. The arc structure on the front and back sides of the long hole 5 avoids stress concentration that could cause the edge of the long hole 5 to crack, thus realizing the adjustment of the connector installation position and structural protection, and improving the installation adaptability of the connector.
[0021] Working principle: According to the photovoltaic panel installation scenario and connection quantity requirements, select the corresponding type of connection mechanism 2. You can choose either double-sided plate 21 or single-sided plate 23. If you need to connect photovoltaic panels on both sides at the same time, select double-sided plate 21. Make the mounting surface of the bottom of double-sided plate 21 completely fit with the preset mounting area on the top of the middle plate 1, ensuring that the U-shaped structure opening of double-sided plate 21 faces upward, and the first round hole 22 at the bottom of double-sided plate 21 is initially aligned with the fourth round hole 4 at the top of the middle plate 1. If you only need to fix one photovoltaic panel, select single-sided plate 23. Place the bottom of single-sided plate 23 on the top of the middle plate 1, so that the left edge of single-sided plate 23 is aligned with the left edge of the top of the middle plate 1. The second round hole 24 on the inner side of single-sided plate 23 corresponds to the fourth round hole 4 of the middle plate 1. When using double-sided plates 21, since double-sided plates 21 can connect photovoltaic panels on both sides simultaneously, the mounting edges of the photovoltaic panels on both sides are slowly placed into the left and right sides of the U-shaped groove of the double-sided plates 21 respectively. The positions of the photovoltaic panels on both sides are adjusted so that the mounting holes on the edges of the photovoltaic panels on both sides are completely aligned with the long holes 5 on the corresponding sides of the top of the middle plate 1, ensuring that the bolts can pass through smoothly. Then, take bolt 25 and pass it through from the top of the photovoltaic panel mounting hole downwards. Bolt 25 passes through the photovoltaic panel mounting hole, the round hole 22 of the double-sided plates 21, and the long hole 5 of the middle plate 1 in sequence. Thread nut 26 is connected to the bottom of bolt 25. Use a tool to tighten nut 26 until the inner wall of the double-sided plates 21 and the mounting edges of the photovoltaic panels on both sides are tightly fitted. The middle plate 1 provides stable support for the double-sided plates 21 through the clamping force of bolt 25 and nut 26. When using a single-sided panel 23, since the single-sided panel 23 only fixes one side of the photovoltaic panel, the mounting edge of the single-sided photovoltaic panel is attached to the right side surface of the single-sided panel 23. The photovoltaic panel is moved so that the mounting hole is aligned with the elongated hole 5 of the middle plate 1. The bolt 25 is passed through the top of the photovoltaic panel mounting hole, and then through the photovoltaic panel mounting hole, the round hole 24 of the single-sided panel 23 and the elongated hole 5 of the middle plate 1 in sequence. The nut 26 is screwed into the bottom of the bolt 25 and tightened. The reverse folding structure of the single-sided panel 23 forms a lateral limit on the photovoltaic panel, preventing the photovoltaic panel from shifting laterally, and realizing the fixed splicing of the single-sided photovoltaic panel. Take bolt 2 31 and align its bottom with the round hole 4 at the top of the middle plate 1. Insert bolt 2 31 downwards through the round hole 4. If using double-sided plates 21, bolt 2 31 will also pass through the round hole 22 at the bottom of the double-sided plates 21. If using a single-sided plate 23, bolt 2 31 will also pass through the round hole 24 at the bottom of the single-sided plate 23. Continue downwards through the round hole 34 of the clamp 33 at the bottom of the middle plate 1. Thread nut 2 32 onto the bottom of bolt 2 31. Use a tool to engage the nut 2 32 in the hexagonal groove at the top of bolt 2 31. Tighten the nut 2 32 by rotating the tool, so that the middle plate 1... The connecting mechanism 2 is tightly connected to the clamp 33 to enhance the overall structural stability. Then, the load-bearing cable is placed in the inner arc-shaped area of the clamp 33, and the position of the load-bearing cable is adjusted to be in the center of the clamp 33 to avoid force deviation. Then, another set of bolts 2 31 is passed through the round hole 34 at the opening end of the clamp 33, and nuts 2 32 are screwed in and gradually tightened to make the inner wall of the clamp 33 in close contact with the surface of the load-bearing cable. The arc-shaped structure of the clamp 33 is adapted to the shape of the load-bearing cable, increasing the contact area to prevent the load-bearing cable from sliding and achieving stable fixation of the load-bearing cable. If it is necessary to adjust the installation position of the connector and the photovoltaic panel or external support structure, loosen the nuts of bolt 25 or bolt 31, and slowly move the external connector or photovoltaic panel along the length of the long hole 5 in the middle plate 1 until the appropriate installation spacing is achieved. The arc structure on the front and rear sides of the long hole 5 can disperse stress and prevent cracking at the edge of the long hole 5 due to stress concentration during the movement. After the adjustment is completed, tighten all nuts again to complete the splicing between photovoltaic panels and the connection and fixation of the load-bearing cable.
