DETAILED DESCRIPTION

[0026] The present invention is further described below through specific implementation methods.

[0027] like Figure 1 As shown, the utility model provides a vertical rail assembly of a solar photovoltaic support, comprising a plurality of rails 1 and at least one connecting member 2.

[0028] like Figure 1 , 4As shown, the guide rail 1 includes a first top wall 101, a first bottom wall 102 and two first side walls 103 arranged opposite to each other. The first top wall 101, the first bottom wall 102 and the two first side walls 103 form a hollow first cavity 104. A first thickened protrusion 111 is provided in the middle of the inner side surface of the two first side walls 103. The first thickened protrusion 111 is in the shape of an elongated strip and extends along the length direction of the first side wall 103. In this embodiment, the first top wall 101 is plane and parallel to the first bottom wall 102. The width of the first top wall 101 is smaller than the width of the first bottom wall 102. The two first side walls 103 are parallel to each other and perpendicular to the bottom wall and connected at both ends in the width direction thereof. They are perpendicular to the first top wall 101 and connected at both ends in the width direction thereof through an inclined surface. The closed inner cavity thus formed can provide sufficient torsional rigidity for the structure. Figure 3 , 5 As shown, a wave-shaped protrusion 110 is respectively provided in the middle of the outer side surface of the first side wall 103 . The wave-shaped protrusion 110 extends along the length direction of the first side wall 103 , and the head of the self-tapping screw 3 abuts against the wave-shaped protrusion 110 .

[0029] like Figure 1 , 2 As shown, the connecting member 2 includes a second top wall 205, a second bottom wall 206 and two second side walls 207, and the second top wall 205, the second bottom wall 206 and the two second side walls 207 form a hollow second cavity 201; a guide groove 202 is provided in the middle of the outer side surface of the second side wall 207, and the guide groove 202 is long and extends along the length direction of the second side wall 207, and the first thickened protrusion 111 enters the guide groove 202. The middle of the inner side surface of the second side wall 207 is provided with a second thickened convex portion 203, which is in a strip shape and extends along the length direction of the second side wall 207; the inner side surfaces of the two second side walls 207 are also provided with two convex ribs 204, each convex rib 204 extends along the length direction of the second side wall 207, the second thickened convex portion 203 is located between the two convex ribs 204, and the protrusion of the two convex ribs 204 relative to the inner side surface of the second side wall 207 is greater than the protrusion of the thickened convex portion relative to the inner side surface of the second side wall 207, the self-tapping screw 3 passes through the second thickened convex portion 203, and the two convex ribs 204 clamp the tail of the self-tapping screw 3. The second thickened convex portion 203 has an outwardly convex arc surface, which is distributed up and down at both ends in the circumferential direction. In this embodiment, the connecting member 2 and the matching guide rail 1 also have a closed inner cavity structure. The second thickened protrusion 203 and two ribs 204 in the middle of the closed inner cavity can effectively cooperate with the self-tapping screw 3 to provide sufficient shear strength and bending strength.

[0030] like Figure 1 , 5As shown, the multiple guide rails 1 are distributed in sequence along the length direction, and the two ends of the connecting member 2 are respectively inserted into two adjacent guide rails 1. The first side wall 103 of each guide rail 1 is connected together with the corresponding second side wall 207 of the connecting member 2 by a self-tapping screw 3, and the self-tapping screw 3 passes through the wavy protrusion 110, the first thickened protrusion 111, and the second thickened protrusion 203 in sequence, and is clamped by the two ribs 204.

[0031] like Figure 4 As shown, the guide rail 1 also includes two upper side walls 105, which are respectively arranged at the two ends of the top of the first top wall 101 in the width direction. The inner side tops of the two upper side walls 105 are respectively provided with inner retaining edges 106, and a notch 107 is formed between the inner retaining edges 106 of the two upper side walls 105. The tail end of the inner retaining edge 106 is provided with a downward hook 108, which is convenient for the photovoltaic panel to be reliably connected with it through fasteners such as a card block. The outer side tops of the two upper side walls 105 are respectively provided with outer retaining edges 109, which can strengthen the strength of this open space, and at the same time increase its contact area with the photovoltaic panel and increase friction. Since the photovoltaic panel is pressed on the top of the two upper side walls 105 during installation, it also encloses a closed space, providing sufficient torsional rigidity for the structure. The first bottom wall 102 is respectively provided with outwardly extending card edges 112 at both ends in the width direction, and a card slot 113 is formed between the card edge 112 and the corresponding lower side wall for connecting an external bracket. The cross-sectional height a of the guide rail 1 is 71-78 mm, and the cross-sectional width b of the guide rail 1 is 43-48 mm. The cross-sectional shape of the guide rail 1 is flat "pot" shaped, and compared with other guide rails 1 with higher height and wider width, it is stronger and more reliable under the same weight of material.

[0032] During construction, first, half of the length of the matching connector 2 is inserted into the first cavity 104 of one guide rail 1 to be connected, and then self-tapping screws 3 are fixed at the designated positions at both ends of the guide rail 1; then, the other end of the connector 2 is inserted into the first cavity 104 of the other guide rail 1 to be connected, and then self-tapping screws 3 are fixed at the designated positions at both ends of the guide rail 1, and the connection work of the two guide rails 1 is completed. The designated position is located at the trough of the wave-shaped protrusion 110 of the guide rail 1 and the second thickened protrusion 203 of the connector 2. The guide groove 202 of the connector 2 and the first thickened protrusion 111 of the guide rail 1 are mutually adapted, and at the same time play a guiding role.

[0033] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
