Embodiment 1

[0024] like figure 1 As shown, the cross-section of the profile is approximately L-shaped or inverted T-shaped. The profile is composed of a bottom plate 1, a top groove 3 and a support plate 2. The top groove 3 is provided with a groove 4 along the axis, and the groove 4 The opening is located on the side of the top groove 3. The bottom plate 1 extends horizontally toward the opening side of the groove 4 . The lower plane of the top groove 3 and the upper plane of the bottom plate are respectively provided with two raised ribs 5 .

Embodiment 2

[0026] All the other are identical with embodiment 1, and difference is, as figure 2 As shown, the lower plane of the top groove 3 and the upper plane of the bottom plate 1 are respectively provided with a raised rib 5, and the rib 5 is located on the extended side of the bottom plate.

Embodiment 3

[0028] All the other are identical with embodiment 1, and difference is, as image 3 As shown, the lower plane of the top groove 3 and the upper plane of the bottom plate 1 are respectively provided with a protruding rib 5, and the rib 5 is located on the other side of the extension of the bottom plate.

Abstract

A polyurethane section bar is used for a solar panel frame. The section bar is a strip component made of glass fiber reinforced polyurethane material, the cross section of the component is of an approximate L-shaped structure, and the L-shaped structure comprises a bottom plate, a top groove and a supporting plate, the supporting plate is arranged between the bottom plate and the top groove, and an opening of the top groove faces toward the side face. According to the section bar made of the glass fiber reinforced polyurethane material, the glass fiber reinforced polyurethane material is adopted to replace aluminum alloy material and is good in rigidity, corrosion resistance and insulativity, the section bar is stable in structure, good in anti-bending and anti-torsion performance and low in production cost, and the assembled frame is light in weight and high in anti-bending and anti-torsion strength and is a novel section bar.

Description

technical field [0001] The invention relates to a profile, in particular to a glass fiber reinforced polyurethane solar panel profile. Background technique [0002] Solar bracket photovoltaics on the market are generally assembled from aluminum alloy profiles. Although the aluminum alloy profile is economical and cheap, it has poor corrosion resistance and insulation, and the torsion coefficient is not high. The profile has a cavity structure, the mold structure is complex during production, and more materials are used. Poor bending and torsional performance. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a polyurethane profile with good bending and torsion resistance, light weight, low cost, good bending, torsion and corrosion resistance, and good insulation performance. [0004] In order to achieve the above object, the technical solution of the present invention is as follows: a glas...
