But the elastic modulus of aluminum profile is low and the cost is high, and the price is much higher than that of carbon steel material. Carbon steel material cannot be extruded like aluminum profile, and is usually used as track by punching holes on C-shaped steel up and down, but because of the diversity of assembly specifications and the difference of column span, C-shaped steel needs to make different number of holes and hole positions according to the different needs of actual scheme on site, which leads to low universality of carbon steel track. Therefore, it is necessary to design a photovoltaic support assembly with good universality, low cost and reliable assembly. SUMMARY

[0010] Further, the upper side wall and the lower side wall of the groove are both inclined downward from the groove opening to the groove bottom, and the inclination angle of the upper side wall is greater than that of the lower side wall.

[0011] Further, the first connecting portion is a pre-embedded groove which is arranged along the length direction of the box type slide rail and is made of a plate material through a roll forming process.

[0029] As Figures 1-5 shown, a track type photovoltaic support assembly includes a box type slide rail 1, a support beam 2, a first pressing block 3 and a second pressing block 4. The specific structure of each component will be described one by one below.

[0030] (I) Box type slide rail

[0031] AsFigure 2 and Figure 3 As shown in FIG. 1, the box-shaped slide rail 1 is made of a plate material through a roll forming process. As preferred, the plate material is a carbon steel plate, especially a carbon steel plate with a layer of alloy plating on the surface. The alloy plating includes but is not limited to zinc-aluminum-magnesium.

[0032] Specifically, the box-shaped slide rail 1 includes an upper surrounding surface 11, one side surrounding surface 12, a lower surrounding surface 13 and another side surrounding surface 12, which are sequentially connected to form a box-shaped structure. During processing, the plate material is bent into the upper surrounding surface 11, the one side surrounding surface 12, the lower surrounding surface 13 and the another side surrounding surface 12 along the width direction through the roll forming process, and the two ends of the plate material in the width direction are arranged on the lower surrounding surface 13, and are welded with each other to form a welded joint 130.

[0033] The structure of the welded joint 130 is that the plate material is provided with a fourth bending section 131 and a first U-shaped bending section 132 which are sequentially connected at one end in the width direction, and is provided with a second U-shaped bending section 133 at the other end in the width direction through the roll forming process. The first U-shaped bending section 132 and the second U-shaped bending section 133 are mutually buckled and welded, and the fourth bending section 131 is attached to the bending part of the second U-shaped bending section 133, thereby forming the welded joint 130. Of course, the welded joint 130 can also be arranged on other surrounding surfaces.

[0034] As shown in FIG. 1, Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The upper surrounding surface 11 is provided with a first connecting part for fixing and assembling the photovoltaic panel 5 through the roll forming process, and the first connecting part includes but is not limited to a pre-buried groove 110. The cross-sectional inner profile of the pre-buried groove 110 is inverted T-shaped, and is arranged along the length direction of the box-shaped slide rail 1 (i.e. the length direction of the plate material).

[0035] As shown in FIG. 1, Figure 2 and Figure 3 The side surrounding surface 12 is provided with a groove 120 through the roll forming process, the groove 120 is arranged along the length direction of the box-shaped slide rail 1, and the lower side wall of the groove 120 is arranged downwardly inclined from the groove opening to the groove bottom.

[0036] Specifically, the first connecting section 121, the first bending section 122, the second bending section 123, the third bending section 124 and the second connecting section 125 which are sequentially connected from top to bottom are processed through the roll forming process, thereby forming the side surrounding surface 12. Among them, the first connecting section 121 is connected with the upper surrounding surface 11; the groove 120 is composed of the first bending section 122, the second bending section 123 and the third bending section 124; and the second connecting section 125 is connected with the lower surrounding surface 13.

[0037] As shown in FIG. 1, Figure 2, Figure 3 , Figure 7 and Figure 8 As shown, the upper sidewall of the groove 120 is formed by a first bent section 122; the lower sidewall of the groove 120 is formed by a third bent section 124. Preferably, both the upper and lower sidewalls of the groove 120 are inclined downwards from the groove opening to the groove bottom, and the inclination angle of the upper sidewall is greater than that of the lower sidewall. In this way, the groove opening of the groove 120 is larger than the groove bottom, which facilitates the placement of the first pressing block 3.

[0038] (ii) Supporting beam

[0039] like Figure 1 As shown, the support beam 2 includes, but is not limited to, hollow square steel with a rectangular cross-section.

[0040] (III) First pressing block

[0041] like Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, one end of the first pressing block 3 is provided with a first abutting part 31 that is inclined downwards, and a second abutting part 32 that is vertically downwards; the other end of the first pressing block 3 is provided with a third abutting part 33.

[0042] (iv) Second pressing block

[0043] like Figure 1 and Figure 5 As shown, the second pressure block 4 has an upper pressure plate 41 at one end and a lower pressure plate 42 at the other end. The upper pressure plate 41 is horizontally arranged, and the lower pressure plate 42 is vertically arranged.

[0044] (v) Assembly and use

[0045] like Figures 1-8 As shown, the assembly steps of this utility model are roughly as follows:

[0046] a. Assemble multiple support beams 2 in a spaced-out arrangement;

[0047] b. Multiple box-shaped slide rails 1 are placed on multiple support beams 2 at intervals, and each box-shaped slide rail 1 is locked to the support beam 2 by multiple first pressure blocks 3 in conjunction with bolts (including screws and nuts). Specifically, when the first pressure block 3 is locked to the support beam 2 by bolts, the first abutting part 31 abuts against the third bending section 124 (i.e., the lower side wall of the groove 120), the second abutting part 32 abuts against the second connecting section 125 of the side wall 12, and the third abutting part 33 abuts against the upper end face of the support beam 2, thereby locking the box-shaped slide rail 1 to the support beam 2.

[0048] c. Put the photovoltaic panel 5 on the plurality of box-shaped slide rails 1, and lock the photovoltaic panel 5 on the box-shaped slide rails 1 by cooperating the bolts (including screws and nuts) with the blocks. Repeat step c. for multiple times to lock the plurality of photovoltaic panels 5 on the plurality of box-shaped slide rails 1.

[0049] Taking the photovoltaic panel 5 installed at the edge position as an example, the photovoltaic panel 5 is locked on the box-shaped slide rail 1 by cooperating the bolts (including screws and nuts) with the second block 4. Specifically, the screw in the bolt is placed in the embedded groove 110 in advance, and then the second block 4 is locked on the box-shaped slide rail 1 through the embedded groove 110 by the nut; after the second block 4 is locked, the lower pressing plate 42 abuts against the embedded groove 110, and the upper pressing plate 41 abuts against the upper end face edge of the photovoltaic panel 5.

[0050] In addition, the existing blocks for locking the photovoltaic panel 5 on the box-shaped slide rail 1 are various, and the person skilled in the art can select the appropriate existing block according to the needs.

[0051] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-substantial change to the present application using this concept shall be deemed as an infringement of the protection scope of the present application.
