[0041] As a further improvement of this utility model, the connecting plate 3 is provided with several connecting holes, which are arranged side by side in sequence.

[0044] Specifically, the fixing buckle 5 is made of 1.5mm galvanized sheet bent into shape, and has a locking part 8 inside.

That is, the fixing buckle 5 is fixed to the four corners of the slot through the locking part 8 and hooked onto the inclined beam 4 for fixing the concentrator.

[0045] It should be noted that in this embodiment, there are three bases 1 and three inclined beams 4. Fixing buckles 5 are respectively provided on the two opposite sides of the middle inclined beam 4, while fixing buckles 5 are respectively provided on the two outer inclined beams 4 facing the middle inclined beam 4.

[0046] The fixed bracket of this utility model is characterized by simple installation, ensuring installation accuracy and improving fixing strength; by setting multiple adjustment holes 7, each adjustment hole 7 is spaced at 1°, it has the characteristics of simple installation tilt angle adjustment, high accuracy (adjustment per degree), and meeting the installation requirements of different dimensions; by using purlins 6 to evenly support the concentrator, it releases the thermal expansion deformation of the concentrator under large temperature difference and solves the problem of concentrator deformation.

During specific design, the structural form is designed through three-dimensional simulation, combined with the design principle of triangular stable structure and sheet metal processing technology to design the bracket and ensure its stability. The shape of the sheet metal interface and the thickness of the sheet are determined through finite element simulation calculation; the bracket is processed with loose parts and installed and formed in a modular combination method.

[0048] This bracket is divided into components such as base 1, inclined beam 4, brace 2, connecting plate 3, purlin 6, and fixing buckle 5.

Its lower end is fixed to the base 1 with a single point.

[0052] The brace 2 selects a 1.5mm galvanized sheet as the material and is bent into a trough - shaped structure. Its lower end is fixed to the base 1 with a single point and is fixed to the inclined beam 4 through the connecting plate 3 to form a triangular stable structure.

[0053] The purlin 6 selects a 1.5mm galvanized sheet as the material and is bent into a "concave" - shaped structure by sheet metal bending, and is installed between the triangular stable brackets to evenly support the concentrator.

[0054] The fixing buckle 5 also uses a 1.5mm galvanized sheet and is formed by sheet metal bending. It is fixed to the four corners of the trough body and hooked to the inclined beam 4 to fix the concentrator. Such a fixing method not only achieves the purpose of fixation but also achieves the free release function.
