Description

Technical Field

[0001] The invention discloses a photovoltaic bracket which is convenient for loading, unloading and migration and belongs to the technical field of photovoltaic brackets. Background Art

[0002] At present, the construction of photovoltaic brackets is mainly completed through prefabricated cement foundations. However, this cement foundation, as the base of the photovoltaic bracket, is not convenient for subsequent position movement and adjustment. In reality, when encountering special circumstances such as expiration of property rights, demolition, change of site use, etc., and the photovoltaic array needs to be relocated, the bracket cement foundation needs to be destroyed to dismantle the corresponding photovoltaic bracket and recycle it. The cost of foundation migration is too high, resulting in the inability to continue to use it in the future. When it is installed again, a new cement base foundation needs to be remade. Building a new photovoltaic panel array wastes extra time and increases unnecessary economic expenditures.

[0003] In addition, according to the feedback from photovoltaic panel maintenance personnel, due to the lack of additional piling, most of the precast cement foundations are not firmly connected to the ground. When encountering extreme weather such as wind and rain, the entire bracket is prone to large movement, and it will also cause the entire photovoltaic bracket to deform as a whole. The precast cement foundations that are currently used frequently in the industry can no longer meet the requirements of photovoltaic bracket construction and relocation. Summary of the invention

[0048] At least two groups of the mounting grooves 21 are installed in a vertical direction of the support base 1;

[0056] The distance between two adjacent support bases is 100 - 200 cm;

[0057] The size of the support base 1 is: diameter 30 - 60 cm, height 30 - 50 cm.

[0058] The present invention provides a fixed and easily relocatable photovoltaic support for existing photovoltaic power generation systems. Usually, the foundation of a photovoltaic support is completed by precasting cement. The precast foundation is not convenient to move. When it is necessary to relocate the photovoltaic array in some special cases, the relocation cost is high, resulting in its inability to continue being used. When reinstalling, a new precast foundation is required again, which not only prolongs the relocation progress but also increases the economic expenditure. To address the above problems, the present invention improves the structure of the photovoltaic support to meet the requirements of weight balance and convenient assembly and disassembly at the same time.

[0059] The photovoltaic support foundation provided by the present invention is composed of modules. The provided base foundation of the photovoltaic support mainly consists of a shell made of galvanized steel material and slots provided on the surface and inside, enabling flexible disassembly and assembly of the entire photovoltaic support. In some special cases, the foundation can be directly disassembled and relocated. In addition, the external connecting components of the galvanized steel shell can be directly connected to grounding components such as angle steel, increasing the wind resistance of the entire photovoltaic support array.

[0060] In the embodiment of the present invention, the dimensional specifications of the components used are as follows:

[0061] The present invention forms a support array by setting fixed brackets and crossbeams, and installs photovoltaic modules on the formed support array. The photovoltaic modules adopt industry-standard polysilicon 60 modules. The module dimensional specifications are 1650mm×992mm, the frame thickness is 35mm, the module arrangement method is vertical double-row arrangement, and the column spacing between the front and rear support bases is 2m.

[0062] The structure of the support base foundation is a cylinder, and it can also be adjusted to the shape of a regular tetrahedron, a rectangular body, etc. according to needs during use. The size of the support base foundation is 500mm (diameter)×400mm (height), and the actual size can be flexibly adjusted according to the design configuration requirements. The support base consists of two parts: an outer shell and a top surface. The outer vertical surface and the bottom surface are directly welded together. The top of the outer shell is movably installed with a top cover through a locking device.

[0063] All the component modules used in the present invention are made of hot-dip galvanized steel plates. The thickness of the steel plates is preferably 4mm. Except for the top cover of the support base, the outer vertical surface and the bottom surface are directly welded together. When prefabricating the foundation, the filler is directly placed into the support base. When closing the top cover, it is required that the U-shaped connecting piece inside the top cover is buried in the filler. The foundation U-shaped embedded part is connected to the bottom surface through the installation holes. Before filling the filler, it is also necessary to ensure that the support base is reliably connected to the ground through binding to prevent the base foundation from shifting due to environmental factors. In addition, universal wheels can be additionally provided at the bottom of the base foundation according to needs to facilitate fine position adjustment and improve the adaptability of the photovoltaic support in use.

[0064] Connection holes are reserved inside the base foundation, aiming to connect and reinforce adjacent base foundations through additional connecting rods, similar to the reinforcement bar implantation of precast foundations. After the foundation assembly is completed, the contents are loaded into the foundation. According to the size of the base foundation, the total weight of fine sand of the same volume is 102 kg (basis for fine sand weight conversion: 1.3 t / cubic meter). After the foundation is filled with fine sand, the total weight is required to be greater than 110 kg. Through design verification, this weight can meet the counterweight requirements of the above-mentioned support array scheme.

[0065] The components connected to the outside of the base foundation are independent components. Installation grooves for external connectors are provided in their south, north, and side directions. The installation grooves are connected and fixed to the side wall of the base through bolts. The front and rear column foundations of the support can be connected and fixed through purlins by external connectors, which increases the stability of the entire photovoltaic array. In addition, the external connectors on the other side of the foundation can be connected to the grounding device according to requirements, further increasing the wind resistance of the whole.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
