Description

Photovoltaic module mounting frame for high latitude environment

technical field

The invention relates to a photovoltaic module installation frame, in particular to a photovoltaic module installation frame that can ensure economical efficiency, improve practicality and aesthetics, and is more suitable for high-latitude belt environments.

Background technique

Affected by the photovoltaic environment, large-scale photovoltaic power station projects have been expanding rapidly in the past two years, and competition among enterprises has intensified. Among them, the construction of photovoltaic power plants also needs to comprehensively consider the structural economy, practicality and aesthetics of the photovoltaic module mounting racks used.

Most of the existing mounting frames are made of carbon steel. Since carbon steel has high hardness and strength, its plasticity is also low. The mounting frame made of this carbon steel is also limited to be made into a relatively regular shape, such as a rectangle or a simple bent shape, so this type of mounting frame can only play a simple supporting role for the photovoltaic module, and its mechanical performance Generally poor, it also affects the practicality of the mounting bracket. Simultaneously, since the shapes of such mounting frames are some relatively common shapes, the aesthetics thereof are generally poor.

In addition, most of the existing mounting frames are general-purpose mounting frames used in various terrain environments, and have not fully considered the installation angle of photovoltaic power plants in some specific environments, especially in high-latitude environments. The difference between the installation angles under the latitude belt will inevitably affect the force effect of the installation frame on the photovoltaic module, so it will also affect the practicability of the installation frame to a certain extent.

Therefore, we urgently need a new type of photovoltaic module mounting frame that can ensure economics, improve practicability and aesthetics, and is more suitable for high-latitude environments.

Contents of the invention

The purpose of the present invention is to overcome the defects of the prior art, and provide a photovoltaic module mounting frame that can ensure economic efficiency, improve practicality and aesthetics, and is more suitable for high-latitude environments.

The technical solution for realizing the purpose of the present invention is: a photovoltaic module mounting frame for high-latitude environment, including:

The upper mounting surface and the lower mounting surface are arranged parallel to each other;

At least one main rib, which is arranged between the upper installation surface and the lower installation surface, and forms a Z-shaped structure with the upper installation surface and the lower installation surface, and the at least one main rib is also connected to the upper installation surface and the lower installation surface. The lower mounting surface forms an included angle, and the included angle is 50°-130°;

A plurality of inclined ribs, the two ends of which are respectively arranged on the main rib and the upper mounting surface and/or the lower mounting surface to form a triangular cross-section;

The upper mounting surface, the lower mounting surface, the main reinforcement and the oblique reinforcement are aluminum profiles.

Further, there are two oblique bars, and the two oblique bars are arranged in parallel.

Further, the upper mounting surface, the lower mounting surface, the main ribs and the inclined ribs are integrally formed.

Further, the thickness of the main rib is 2.5-3.0mm.

Further, the thickness of the oblique ribs is 1.5-2.0mm.

Further, the thickness of the upper installation surface is 2.5-2.8 mm, and the thickness of the lower installation surface is 2.5-2.8 mm.

The present invention has positive effects: the photovoltaic module mounting frame of the present invention is mainly composed of an upper mounting surface made of aluminum profiles, a lower mounting surface, at least one main rib and multiple heel bars, wherein the upper mounting surface and the lower mounting surface are mutually Arranged in parallel, the main reinforcement is arranged between the upper installation surface and the lower installation surface, and forms a Z-shaped structure with the upper installation surface and the lower installation surface. Form a triangular cross-section, because the plasticity of the aluminum profile is strong, so the present invention makes full use of the plasticity to make the structure of the mounting frame through a process such as hot-melt extrusion molding. In this structure, the main rib forms a vertical direction for the photovoltaic module. That is, the support in the direction of gravity, multiple oblique ribs support the photovoltaic module laterally, that is, support in a direction at a certain angle to the horizontal direction, so that the cooperation between the oblique ribs and the main ribs can form multi-directional support for the photovoltaic module , compared with the prior art, it has a better force bearing effect, which improves the practicability of the mounting frame, and the oblique ribs can also enhance the twist resistance of the mounting frame during the extrusion molding process; the main ribs are also in contact with the upper mounting surface and the The lower installation surface forms an included angle of 50° to 130°. The setting of the included angle fully considers the installation angle of photovoltaic power plants in high latitudes. After testing, the installation frame with this installation angle is more suitable than the existing technology. The installation angle of the photovoltaic power station in the latitude zone has better stress effect and stronger practicability; the new shape design of the photovoltaic module installation frame of the present invention breaks the regular shape design of the installation frame in the prior art , on the basis of not increasing the production cost, the practicability of the present invention is ensured, and the economy of the installation frame is also ensured.
