Problems solved by technology

[0005] The present invention aims at the technical problem in the prior art that photovoltaic modules are damaged or cells are cracked due to uneven foundation settlement, which brings serious harm to the later operation of photovoltaic power stations, and provides a photovoltaic system suitable for foundation sites prone to foundation settlement. The component installation bracket solves the damage to the photovoltaic module caused by the sub-internal force generated in the support platform structure caused by the subsidence of the ground support pile foundation in the weak foundation site; at the same time, it solves the problem that the component surface is subjected to a large impact force when the component is subjected to a large wind load The problem of cracking cells in the module

Embodiment 1

[0035] Such as Figure 1-8 As shown, the photovoltaic module installation bracket of the present invention, which is suitable for foundation sites prone to foundation settlement, is used to fix the photovoltaic module 100 on the installation surface 101. A group of beams 2 on 1, the photovoltaic module 100 is installed on the beam 2, the photovoltaic module 100 is elastically arranged on the beam 2, and the column 1 is elastically arranged on the installation surface 101. The installation surface generally refers to the site where the photovoltaic module is installed, which may be a flat surface or a slope surface, which is not limited in the present invention.

[0036] Specifically, such as Figure 1-2 As shown, the beam 2 includes a slanted beam 21 and a crossbeam 22, the slant beam 21 is connected to the column 1, the crossbeam 22 is connected to the slant beam 21, the photovoltaic module 100 is arranged on the beam 22, and an inclined beam 21 and the column 1 are also pro...

Embodiment 2

[0041] Such as Figure 8-10 The difference between the shown embodiment and Embodiment 1 is that the column 1 is connected to the installation surface 101 through the preset steel pipe pile 5, a column base 12 is provided near the bottom end of the column 1, and a steel pipe pile 5 is provided with a There is a flange plate 51, the end of the column 1 is sleeved in the steel pipe pile 5, the column base 12 and the flange plate 51 are connected by bolts, and an elastic member 3 is arranged between the column base 12 and the flange plate 51. In the embodiment, the elastic member 3 is a spring.

[0042] Figure 9 It shows a schematic structural diagram of a spring arranged between the column 1 and the steel pipe pile 5 in this embodiment, Figure 10 A schematic structural view of the column base in this embodiment is shown.

[0043] Similarly, this embodiment also uses the elastic deformation of the elastic member to absorb the partial stress generated in the support member du...

Embodiment 3

[0045] Such as Figure 11-13 As shown, this embodiment is a further improvement on the basis of Embodiment 1 and Embodiment 2, specifically: each crossbeam 22 includes a left crossbeam 22a and a right crossbeam 22b respectively, and the passage between the left crossbeam 22a and the right crossbeam 22b A connecting plate 22c is hinged, the left beam 22a and the right beam 22b are respectively provided with photovoltaic modules 100 and the junction of the left beam 22a and the right beam 22b is not provided with a photovoltaic module. Such as Figure 11 As shown, eight pile foundations (four pairs in the north and south) are selected for the unit square array in this embodiment, and the photovoltaic modules and the beams are connected by bolts, in which a support beam is divided into two sections, and the middle connection is a hinged connection, and the photovoltaic modules cannot be bridged between two paragraphs.

[0046] Divide each support beam into two sections and conn...

Abstract

The invention discloses a photovoltaic module mounting bracket applicable to foundation sites prone to foundation settlement, and belongs to the technical field of photovoltaic modules. The photovoltaic module mounting bracket is used for fixing a photovoltaic module (100) to a mounting surface (101). The photovoltaic module mounting bracket comprises a set of columns (1) arranged on the mounting surface (101) and a set of beams (2) arranged on the columns (1). The photovoltaic module (100) is mounted on the beams (2). The photovoltaic module mounting bracket is characterized in that the photovoltaic module (100) is elastically arranged on the beams (2), and / or, the columns (1) are elastically arranged on the mounting surface (101). According to the invention, the photovoltaic module is elastically arranged on the beams, and / or, the columns are elastically arranged on the mounting surface, and elastic deformation is used to absorb part of the stress produced in the bracket component due to uneven foundation settlement, relieve bracket component deformation caused thereby, reduce the damage to the photovoltaic module due to bracket deformation and avoid hidden cracking of cells in the photovoltaic module.

Description

technical field [0001] The invention relates to a photovoltaic module installation bracket, in particular to a photovoltaic module installation bracket suitable for foundation sites prone to foundation settlement, and belongs to the technical field of photovoltaic modules. Background technique [0002] The large-scale ground photovoltaic power station is composed of many unit square arrays, and the unit square array is composed of photovoltaic brackets and photovoltaic modules, and its core components are photovoltaic modules. As a fixed platform for photovoltaic modules, the bracket needs to have sufficient safety, applicability, and durability, that is, it needs to have enough structural strength to withstand the loads transmitted from the surface of various components, and have sufficient strength to withstand various loads transmitted from the surface of the components. The effect of the load under working conditions meets the specified deformation of the support structu...
