Description

Technical Field

[0002] The edges and corners of the tempered glass (photovoltaic laminate) in photovoltaic modules are fragile. In order to protect the tempered glass, it is necessary to wrap a frame around the edge of the tempered glass, and use the frame and silicone to seal the edge of the tempered glass to provide support and protection for the tempered glass.

[0003] At present, most of the frames of photovoltaic modules have C-side frames, such as Figure 1 As shown, the C surface is commonly referred to by technicians in this field as the side of the frame away from the tempered glass. A mounting hole is set on the C surface. Due to the setting of the mounting hole and the insufficient wall thickness of the C surface, the mounting hole on the frame of the photovoltaic module is very easy to deform, affecting the installation of the photovoltaic module.

[0004] At the same time, when actually installing a photovoltaic module using this type of frame (a frame with a C surface), it is necessary to place the photovoltaic module, align the mounting holes on the photovoltaic module with the screw holes at the mounting location, and connect and fix them with bolts. Two adjacent photovoltaic modules also need to be fixed with a pressing block. During the entire installation process, there are often problems such as misalignment of the holes (mounting holes and screw holes) and falling of the screws. The installation process is complicated, which greatly increases the installation cost of the photovoltaic module and prolongs the installation period.

[0005] In addition, when the frame of this structure (frame with C surface) is installed on the roof, there is a gap between two adjacent photovoltaic modules, and rainwater will flow from the gap between the two adjacent photovoltaic modules to the roof, making the photovoltaic module not suitable for rooftop distribution.

[0043] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] Example:

[0045] This embodiment provides a photovoltaic system, such as Figure 2 As shown, it includes a photovoltaic component 1 and a connector 2; wherein,

[0046] See also Figure 3 , a connecting portion A1114 is provided on the side of the photovoltaic module 1;

[0047] The connector 2 is a columnar structure, which makes it easier and more convenient to confirm the position of the connector 2. A mounting hole 21 is provided on the connector 2. The mounting hole 21 on the connector 2 can be easily aligned with the screw hole at the installation location, so that the connector 2 can be connected and fixed with the screw hole at the installation location through a fastener passing through the mounting hole 21; both sides of the connector 2 are provided with a connecting part B22 that matches the connecting part A1114, and the photovoltaic component 1 is detachably clamped on the connector 2 through the cooperation of the connecting part A1114 and the connecting part B22 to complete the installation and fixation of the photovoltaic system.

[0048] The photovoltaic assembly 1 in the photovoltaic system can be mounted on the connector 2 by means of the matching of the connector A1114 and the connector B22;

[0049] During the installation of the photovoltaic system, since the columnar structure of the connector 2 has fewer constraints, the staff can easily align the mounting hole 21 on the connector 2 with the screw hole at the installation location, and use fasteners to install and fix the connector 2 at the installation location;

[0050] The photovoltaic component 1 is then clamped on the connector 2 through the connection part A1114 and the connection part B22 to easily complete the installation of the photovoltaic system, thereby effectively reducing the construction period of the photovoltaic system, and the two adjacent installation components 1 do not need to be fixed with a pressure plate to reduce the use of materials, thereby effectively reducing the installation cost of the photovoltaic system.

[0051] Specifically, the number of the photovoltaic modules 1 is N, and the number of the connectors 2 is N+1; when installing the photovoltaic system, the staff can first install and fix all the connectors 2 at the installation location, and make the distance between two adjacent connectors 2 match the width of the photovoltaic module 1;

[0052] Then, the photovoltaic assembly 1 is connected and matched with the connection parts B22 on two adjacent connection members 2 through the connection parts A1114 on both sides thereof to fix the photovoltaic assembly 1, thereby completing the installation of the photovoltaic system;

[0053] This installation method can reduce the difficulty of installing the photovoltaic system, and when the photovoltaic module 1 has not entered the installation site, the staff can install the connector 2 according to the size of the photovoltaic module 1. After the photovoltaic module 1 enters the site, the installation of the photovoltaic module 1 can be completed quickly to improve construction efficiency.

[0054] It should be noted that the length of the above-mentioned connector 2 can be selected as needed, and it only serves to fix the photovoltaic module 1. Therefore, the length of the connector 2 is not necessarily the same as the length of the photovoltaic module 1. Shortening the length of the connector 2 can achieve the effect of saving materials, thereby further reducing the installation cost of the photovoltaic module 1. In order to better illustrate the photovoltaic system, in this embodiment, the length of the connector 2 is greater than or equal to the length of the photovoltaic module 1.

[0055] The above-mentioned fasteners refer to fastening devices commonly used in the prior art such as screws, bolts and pins that can fasten two components.

[0056] See also Figure 6 , Figure 7 Figure 8 , the above-mentioned connection part A1114 is a tenon, and the connection part B22 is a tenon groove; specifically, the cross-sectional shape of the connection part A1114 is a "T"-shaped tenon, such as Figure 6 As shown, the connection portion A1114 extends along the length direction of the photovoltaic assembly 1;

[0057] The connection part B22 is a "T"-shaped groove matching the connection part A1114. Figure 7 As shown, the connecting portion B22 extends along the length direction of the connecting member 2;

[0058] When installing the photovoltaic module 1, the staff only needs to insert the photovoltaic module 1 into the connection part B22 from one end of the connector 2, and slide the photovoltaic module 1 along the length direction of the connector 2 until the two ends of the photovoltaic module 1 are flush with the two ends of the connector 2 or the two ends of the photovoltaic module 1 are located between the two ends of the connector 2, so as to complete the connection and fixation of the photovoltaic module 1 and the connector 2, that is, to complete the installation of the photovoltaic system, making the installation of the photovoltaic system simpler and more convenient, thereby effectively shortening the installation period of the photovoltaic system;

[0059] Of course, the above-mentioned connection part A1114 and the connection part B22 can also adopt the following structure arrangement:

[0060] The connection part A1114 is a mortise and tenon, and the connection part B22 is a tenon (not shown in the figure);

[0061] Specifically, the connection portion A1114 is a “T”-shaped groove, and the connection portion A1114 extends along the length direction of the photovoltaic module 1;

[0062] The cross-sectional shape of the connection portion B22 is a “T” shape, and the connection portion B22 extends along the length direction of the connection member 2 ; this arrangement can also achieve a quick connection between the connection member 2 and the photovoltaic module 1 .

[0063] Optimally, the above-mentioned mounting hole 21 is a screw hole, and the mounting hole 21 passes through the bottom surface of the connecting member 2 from the top surface of the connecting member 2, and the axis of the mounting hole 21 is perpendicular to the top surface of the connecting member 2, so that the installation of the connecting member 2 is more convenient.

[0064] Optimally, the photovoltaic system also includes a waterproof pressing block 3, see Figure 7 , the fixing surface of the waterproof pressure block 3 is provided with a connecting portion C31;

[0065] The top surface of the connector 2 is provided with a connecting portion D23 matching the connecting portion C31. The waterproof pressure block 3 is detachably mounted on the connector 2 through the matching of the connecting portion C31 and the connecting portion D23. The width of the waterproof pressure block 3 is greater than the width of the connector 2, so that the waterproof pressure block 3 can cover the joint between the connector 2 and the photovoltaic module 1. Fig. 9 As shown, rainwater is prevented from leaking out from the joint between the connector 2 and the photovoltaic module 1, so that the photovoltaic system can be used for rooftop distribution, which can protect the roof and provide waterproofing.

[0066] Optimally, the connection portion C31 is a clamping portion, the cross-section of which is in a T-shape, and the clamping portion extends along the length direction of the waterproof pressure block 3;

[0067] The connecting portion D23 is a slot that matches the clamping portion, that is, the slot is a "T"-shaped slot, and the slot extends along the length direction of the connecting member 2;

[0068] When installing the waterproof pressure block 3, the staff only needs to insert the connection part C31 on the waterproof pressure block 3 into the connection part D23 from one end of the connector 2, and slide the waterproof pressure block 3 along the length direction of the connector 2 until the two ends of the waterproof pressure block 3 are flush with the two ends of the connector 2 to complete the installation of the waterproof pressure block 3.

[0069] It should be noted that the depth of the mounting hole 21 is greater than the depth of the slot. Figure 8As shown, during the installation process, the staff can first use the fastener to pass through the installation hole 21 and connect with the screw hole at the installation location to fix the connecting piece 2, and then clamp the waterproof pressure block 3 in the clamping groove. Since the depth of the installation hole 21 is greater than the depth of the clamping groove, there will be no conflict between the clamping part and the fastener, and thus the fastener will not affect the sealing of the waterproof pressure block 3.

[0070] Optimally, the end of the connecting member 2 is provided with a sliding hole 24, see Figure 7 and Figure 8 , the sliding hole 24 extends along the length direction of the connecting member 2 and penetrates the connecting member 2;

[0071] An opening 25 is provided on a side of the connecting member 2 facing away from the connecting portion D23. The opening 25 is connected to the sliding hole 24, and the width of the opening 25 is smaller than the width of the sliding hole 24.

[0072] When installing the connector 2, the worker can place the nut in the slide hole 24. The width of the selected nut matches the width of the slide hole 24, so that the nut can only slide along the length direction of the slide hole 24, but cannot rotate in the slide hole 24.

[0073] Then the bolt is screwed out from the screw hole at the installation location, passes through the opening 25 and is connected with the nut in the sliding hole 24 , so that the connection member 2 is installed and fixed.

[0074] The provision of the sliding hole 24 can increase the installation methods of the connecting member 2, and the staff can make a selection according to the situation to make the installation of the connecting member 2 more convenient.

[0075] It should be noted that the width of the above-mentioned nut refers to the distance between the two opposite sides of the nut. The two opposite sides of the nut are respectively clamped on both sides of the sliding hole 24, so that the nut can only slide along the length direction of the sliding hole 24, and cannot rotate in the sliding hole 24. During the process of tightening the bolt, the nut will not rotate, so that the bolt can be easily threaded with the nut, making the installation of the connecting member 2 more convenient.

[0076] Optimally, the photovoltaic assembly 1 comprises a frame 11 and a photovoltaic laminate 12; wherein,

[0077] The photovoltaic laminate 12 in this embodiment is in the shape of a quadrilateral. Figure 4 As shown, the shape of the frame 11 matches the shape of the photovoltaic laminate 12, that is, a quadrilateral frame 11. The frame 11 is wrapped around the edge of the photovoltaic laminate 12 to protect the corners of the photovoltaic laminate 12. The connection portion A1114 is arranged on the side of the frame 11 away from the photovoltaic laminate 12, so that the installation of the photovoltaic module 1 is more convenient.

[0078] Of course, the shape of the photovoltaic laminate 12 can also be a triangle, a pentagon, a hexagon, etc., which is not specifically limited here. The quadrilateral photovoltaic laminate 12 mentioned in this embodiment is only to better illustrate the structure of the photovoltaic module 1.

[0079] Optimized, the above-mentioned frame 11 includes a plurality of side strips 111. For the quadrilateral photovoltaic laminate 12 in this embodiment, the number of side strips 111 is four. The heads and tails of the four side strips 111 are sequentially connected to form a quadrilateral frame 11. The connecting portion A1114 is arranged on the side of the side strip 111 away from the center of the frame 11, and the edge of the photovoltaic laminate 12 is clamped on the side of the four side strips 111 away from the connecting portion A1114, so as to protect the corners of the photovoltaic laminate 12.

[0080] Optimally, the frame 11 further comprises a corner piece 13, see Figure 5 ;in,

[0081] The end of the side strip 111 is provided with a socket 1111 matching the shape of the cross section of the corner piece 13, and the sockets 1111 of two adjacent side strips 111 are respectively plugged into the two ends of the corner piece 13 to make the connection of the side strip 111 more stable.

[0082] In this embodiment, the corner piece 13 is an “L”-shaped structure, and the included angle between the two ends of the extension direction is 90°. Two adjacent side strips 111 are respectively inserted at the two ends of the corner piece 13 to complete the connection and fixation of the side strips 111.

[0083] Preferably, screws may be used to penetrate the side wall of the side strip 111 and connect it to the corner piece 13 to further improve the tightness of the connection between the corner piece 13 and the side strip 111 and prevent the side strip 111 from coming off the corner piece 13.

[0084] More preferably, the insertion holes 1111 set at both ends of the side strip 111 are connected to form a cavity to reduce the amount of material used to make the side strip 111, thereby reducing the production cost of the photovoltaic module 1; at the same time, the weight of the side strip 111 is reduced to make the handling and transportation of the photovoltaic module 1 more convenient.

[0085] Optimally, the side of the edge strip 111 facing the center of the frame 11 is provided with a mounting groove 1112 for covering the edge of the photovoltaic laminate 12, and the inner side wall of the mounting groove 1112 away from the plug hole 1111 is provided with a glue cavity 1113, see Figure 6 The sealing cavity 1113 is connected to the mounting groove 1112 , so that the injected sealant can seal and support the photovoltaic laminate 12 , thereby providing good protection for the photovoltaic laminate 12 .

[0086] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
