Description

Technical Field

[0001] The utility model relates to a frame of a photovoltaic module. Background Art

[0002] The periphery of a photovoltaic module is protected by a frame, the main material of which is aluminum alloy, and the frame is composed of three parts, namely a long side, a short side and a corner connector, and the long side and the short side are connected by the corner connector.

[0003] In a project site, the photovoltaic module is installed on a bracket, and there are two installation methods, namely bolt installation and pressing block installation. The mainstream installation method is bolt installation, and when bolt installation is carried out, the frame and the bracket are connected through the installation holes on the long side. Due to different requirements of the project site, the positions of the installation holes are not the same, resulting in different drilling schemes for the same frame design, which causes great difficulties in the processing and manufacturing of the frame. Summary of the Utility Model

[0004] Purpose of the Utility Model: The purpose of the utility model is to provide a frame of a photovoltaic module with adjustable installation hole positions to solve the compatibility problem of the installation holes on the frame.

[0005] Technical Solution: A frame of a photovoltaic module with adjustable installation hole positions includes a long side, on which there is a hole position opening area. In the hole position opening area, taking a position as the center, an installation hole 1 is opened at the center position, and installation holes 2 are symmetrically opened on the left and right sides of the installation hole 1. There is a partition area between the installation hole 1 and the installation holes 2, and an installation hole 3 is opened above or below the partition area. The installation hole 3 and the installation hole 1 and the installation holes 2 have corresponding overlapping areas. The installation hole 1, the installation holes 2 and the installation hole 3 are all waist-shaped holes.

[0006] Furthermore, the installation hole 1 and the installation holes 2 are on the same horizontal line of the long side, the installation hole 3 is parallel to the installation holes 2. The installation hole 1 and the installation holes 2 are used as main installation holes to meet the installation adjustment requirements in the length direction. The installation hole 3 is used as an auxiliary installation hole, and when there is a connection deviation in the width direction, the connection is carried out with the installation hole 3.

[0007] Furthermore, two upper and lower sliding grooves are opened on the hole position opening area. The installation hole 1, the installation holes 2 and the installation hole 3 are all between the two sliding grooves. The retaining pieces are connected to the sliding grooves with two support plates arranged on the bottom surface of the retaining pieces, and the number of the retaining pieces is 2. When the bolt is connected to one of the installation holes, there will inevitably be more exposed installation holes on both sides of the bolt. The retaining pieces can move along the sliding grooves by relying on the support plates, so as to shield the installation holes.

[0008] Furthermore, the retaining pieces are made of flexible silicone material, which can meet the requirements of outdoor use, moving adjustment, filling gaps and shielding installation holes.

[0009] Further, two hole - opening areas are arranged on the long side. Each hole - opening area is installed and connected to a bolt assembly on the bracket to balance the stability and firmness of the installation structure of the entire photovoltaic module.

[0010] Beneficial effects: The advantages of the present utility model are as follows: The combination of the installation holes provides a free - adjustment space for the bolt - type installation connection between the long side of the frame and the bracket. There is no need to have a structure with a large number of circular installation holes formed on the existing long side to form a modular hole structure. The number of installation holes opened is relatively small, and the structural strength of the frame is relatively improved. Moreover, adjustable shielding flaps are provided for the possibly exposed installation holes, which provides a reliable guarantee for the installation connection between the frame and the bolt and the long - term use of the photovoltaic module.

[0012] Figure 2 It is a schematic structural diagram of the flap arranged on the hole - opening area. Detailed Embodiments

[0013] The present utility model will be further clarified below in conjunction with specific embodiments.

[0014] A photovoltaic module frame with adjustable installation holes includes a long side, a short side, and corner codes. The long side and the short side are connected by corner codes. The photovoltaic module is installed on the bracket in a bolt - type manner, and the bolt assembly arranged on the bracket is installed and connected to the long side of the photovoltaic module frame.

[0015] As shown in the Figure 1 drawing, on the long side 1 of the frame of the present application, there is a hole - opening area. Generally, two hole - opening areas are evenly distributed in the length direction of the long side. Each hole - opening area is installed and connected to a bolt assembly on the bracket to balance the stability and firmness of the installation structure of the entire photovoltaic module. In the hole - opening area, taking one position as the center, an installation hole one 2 is opened at this center position. On the left and right sides of the installation hole one 2, that is, in the length direction of the long side 1, installation holes two 3 are symmetrically opened. There is no continuity or communication between the two ends of the installation hole one 2 and the installation holes two 3 on their respective sides, that is, there is a partition area 5. Above or below the partition area 5, that is, in the width direction of the long side 1, an installation hole three 4 is opened. The length of the installation hole three 4 needs to make its two ends have corresponding overlapping areas 6 with the opposite installation hole one 2 and installation holes two 3. The installation hole one 2, installation holes two 3, and installation hole three 4 are all waist - shaped holes. The installation hole one 2 and installation holes two 3 are arranged on the same horizontal line of the long side, and the installation hole three 4 is parallel to the installation holes two 3.

[0016] The structure of the hole opening area. The length spaces of mounting hole 1, mounting hole 2, and mounting hole 3 each provide an adjustable space in the length direction of the long side. Mounting hole 1 and mounting hole 2 are the main mounting holes, meeting the installation adjustment requirements in the length direction. Mounting hole 3 is an auxiliary mounting hole, which is used for connection only when there is a connection deviation in the width direction. When the lower end of the bolt on the bracket extends into the connection, according to the construction conditions at the project site, there is a certain free adjustment space. At the same time, the overlapping area formed by mounting hole 3 and mounting holes 1 and 2 can also meet the connection requirements at the partition area. Since the width of the long side is limited, the distance between mounting hole 3 and mounting holes 1 and 2 in the width direction is also within the controllable deviation range for the installation of photovoltaic modules, without affecting the installation of photovoltaic modules. Since the general connection position is determined when the frame is installed and connected to the bracket, that is, the general range of the hole opening area on the long side is framed, the structure of the hole opening area can meet the adjustment requirements of bolt connection under this premise, and there is no need to have a structure with a large number of circular mounting holes opened on the long side like the existing modular holes. Relatively fewer mounting holes are opened, and the structural strength of the frame is relatively improved.

[0017] Combined with the attached Figure 2 As shown, two upper and lower chutes 11 are also opened on the hole opening area, that is, one is arranged in the width direction of the long side 1 respectively. The length direction of each chute is the same as the length direction of the long side. Mounting hole 1, mounting hole 2, and mounting hole 3 are all located between the two chutes 11. A retaining piece 7 is arranged between the two chutes 11. Two support plates are arranged on the bottom surface of the retaining piece 7. The retaining piece 7 is connected to the two chutes 11 respectively through the two support plates. The retaining piece can move along the chute relying on the support plates. The retaining piece 7 is made of flexible silica gel and the number is 2. After the bolt connection position is determined, the retaining piece is adjusted to be on both sides of the bolt, and then the bolt is connected, so as to shield the mounting hole. Combining each hole opening area with a bolt for connection, after the bolt connection, there will inevitably be more exposed mounting holes on both sides of the bolt. Even if there is a pressing plate for the bolt to pass through on the bolt assembly to partially shield the hole opening area, there will still be dust accumulation in the gaps on both sides of the pressing plate and between the pressing plate and the long side surface. At this time, the retaining piece is located between the pressing plate of the bolt assembly and the long side surface, which can play a role in filling the gap, and the two retaining pieces can completely shield the exposed mounting holes on both sides of the bolt. The material selection of the retaining piece can meet the requirements of outdoor use, moving adjustment on the hole opening area, filling the gap, and shielding.
