Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic components, and in particular relates to a highly stable and easy-to-install photovoltaic frame. Background Art

[0002] When installing existing photovoltaic frames, the connection between the two frames can be installed by screw installation. However, the connection may be unstable, and the strength of the frame itself is insufficient, which will cause the overall stability of the photovoltaic frame to be insufficient, affecting the service life of the photovoltaic frame.

[0003] If ultrasonic welding is used for connection, the photovoltaic frame will still be unstable because the welding and bonding area is too small.

[0004] At the same time, when the existing photovoltaic frame is installed, the horizontal direction between the two frames cannot be limited, and auxiliary parts are required to ensure the vertical state between the two frames, which makes it difficult to connect and install the frames.

[0005] At the same time, if there is an error in the length of the frame or the length and width of the photovoltaic panel assembly during the cutting process, it will be difficult to connect effectively, making the photovoltaic frame difficult to install. At the same time, gaps may appear at the frame connection, causing frame stability. Summary of the Invention

[0006] The purpose of the present invention is to provide a highly stable and easy-to-install photovoltaic frame. By setting a first inclined plate, a second inclined plate and a third inclined plate, the strength of the frame can be improved. At the same time, the first inclined plate, the second inclined plate, the third inclined plate, the inner plate, the upper groove plate, the lower groove plate and the supporting edge can be used in combination to form a first rectangular cavity, a second rectangular cavity, a first triangular cavity and a second triangular cavity, thereby greatly improving the strength of the frame and solving the problem of insufficient stability of the existing photovoltaic frame.

[0007] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The present invention is a highly stable and easy-to-install photovoltaic frame, comprising two sets of frames and two sets of connection components. The frames include side walls, the inner sides of which are provided with an upper groove plate, a lower groove plate and a supporting edge in sequence from top to bottom, and an inner side plate is provided between the supporting edge and the lower groove plate.

[0009] A triangular plate is fixed between one side of the lower trough plate and the inner side plate, a first inclined plate is fixed between the supporting edge and the lower trough plate, the first inclined plate is perpendicular to the inner side of the triangular plate, a second inclined plate is fixed between the first inclined plate and the inner side plate, the first inclined plate is perpendicular to the second inclined plate, a third inclined plate is fixed between the second inclined plate and the inner side of the triangular plate, the third inclined plate is parallel to the first inclined plate;

[0010] A first rectangular cavity is formed between the first inclined plate, the second inclined plate, the third inclined plate and the triangular plate, and a second rectangular cavity is formed between the inner side plate, the side wall, the supporting edge and the lower groove plate;

[0011] The connecting assembly includes a connecting block, wherein a first rectangular block and a second rectangular block are fixed to adjacent surfaces of the connecting block, the first rectangular block is gap-matched with the first rectangular cavity, and the second rectangular block is gap-matched with the second rectangular cavity;

[0012] An L-shaped reinforcement plate is fixed to the other adjacent surface of the connecting block, and a group of threaded holes are opened on an opposite side of the L-shaped reinforcement plate and the second rectangular block. The first rectangular block is located inside the first rectangular cavity, and the second rectangular block is located inside the second rectangular cavity. The L-shaped reinforcement plate and the second rectangular block are respectively located on both sides of the supporting edge and are fixedly connected to the supporting edge through threaded holes and screws.

[0013] Furthermore, an L-shaped cover plate is fixed to the outer edge of the top surface of the connecting block, and the two frames form an L-shaped frame through a connecting component, and a first receiving groove is formed between the L-shaped cover plate and the top surface of the connecting block.

[0014] Furthermore, the two L-shaped frames form a rectangular frame, a second receiving groove is formed between the upper groove edge, the lower groove edge and the side wall on the frame body, and the first receiving groove and the second receiving groove on the rectangular frame are combined into a receiving cavity.

[0015] Furthermore, a first triangular cavity is formed between the supporting edge, the second inclined plate and the first inclined plate, and a second triangular cavity is formed between the third inclined plate, the second inclined plate and the inner plate.

[0016] Furthermore, glue grooves are provided at the edges of the inner side surfaces of the upper trough plate and the inner side surfaces of the L-shaped cover plate, and the cross-section of the glue grooves is a right-angled triangle structure.

[0017] Furthermore, the connecting block is provided with a notch at the corner between the two first rectangular blocks, an inner wall of the notch is flush with a surface of a first inclined plate of one frame body on the L-shaped frame, and another inner wall of the notch is flush with a surface of a first inclined plate of another frame body on the L-shaped frame.

[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention can improve the strength of the frame by arranging the first inclined plate, the second inclined plate and the third inclined plate. At the same time, the first inclined plate, the second inclined plate, the third inclined plate, the inner plate, the upper groove plate, the lower groove plate and the supporting edge can be used in combination to form a first rectangular cavity, a second rectangular cavity, a first triangular cavity and a second triangular cavity. The strength of the frame can be further reinforced by the use of the first triangular cavity and the second triangular cavity, thereby greatly improving the strength of the frame. The photovoltaic frame of the frame combination can greatly improve the stability of the photovoltaic frame.

[0020] 2. The present invention can improve the strength between the frame and the connection component through the coordinated use of the first rectangular block, the second rectangular block, the first rectangular cavity and the second rectangular cavity. At the same time, in conjunction with the L-shaped reinforcement plate, the installation screws pass through the L-shaped reinforcement plate, the second rectangular block and the supporting edge, which greatly improves the fixing ability of the screw installation position and can improve the fixing ability between the connection points of the two frames, thereby indirectly improving the stability of the photovoltaic frame.

[0021] 3. The present invention uses the first rectangular block, the second rectangular block, the first rectangular cavity and the second rectangular cavity in combination. During installation, the length of the first rectangular block and the second rectangular block inserted between the first rectangular cavity and the second rectangular cavity can be adjusted, thereby avoiding the situation where the frame length is inconsistent due to processing errors, the length and width of the photovoltaic panel are not relative to the length of the frame and cannot be effectively connected, or there is a gap at the connection, resulting in insufficient frame stability.

[0022] 4. The present invention facilitates the docking between the connecting component and the frame through the coordinated use of the first rectangular block, the second rectangular block, the first rectangular cavity and the second rectangular cavity, and can pre-limit the position of the frame and the connecting component before or after the screws are installed, thereby facilitating the installation and removal of the photovoltaic frame.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
