Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a photovoltaic support with built-in locking and anti-loosening features and a photovoltaic module installation method. Background Technology

[0002] Photovoltaic support structures are an important component of photovoltaic arrays in solar photovoltaic power generation systems and are an essential part of installing photovoltaic modules. Photovoltaic support structures are mainly divided into two types: fixed and tracking. Among them, fixed support structures are the most widely used in current engineering applications.

[0003] With the increasing demand for carbon neutrality, the demand for photovoltaic power generation construction is also growing, with construction capacity constantly increasing and the demand for land increasing. During the construction and installation process, the installation efficiency of photovoltaic modules will affect the construction progress and construction costs. The main problems with the current photovoltaic mounting system for fixing photovoltaic modules are that, on the one hand, the installation structure and installation procedures are relatively complex, affecting the installation efficiency; on the other hand, the installation process requires a large number of parts, resulting in high installation costs.

[0004] Currently, when installing rooftop or ground-mounted solar photovoltaic systems, clips are used to secure the upper frame of the photovoltaic modules. However, during subsequent use, the clips may come loose due to wind, aging, external forces, or deformation of the photovoltaic module frame, thus affecting the stability of the photovoltaic modules.

[0005] In view of this, it is necessary to develop a photovoltaic bracket and photovoltaic module installation method with built-in locking and anti-loosening features. Summary of the Invention

A fourth inclined plate is provided on the other side of the third horizontal section, and a seventh horizontal section is provided at the end of the fourth inclined plate. A seventh L-shaped buckle and an eighth L-shaped buckle are respectively provided on both sides of the seventh horizontal section. The seventh L-shaped buckle and the eighth L-shaped buckle are supported on the second support surface. The fifth horizontal section passes through the space enclosed by the seventh horizontal section, the seventh L-shaped buckle and the eighth L-shaped buckle.

[0010] Preferably, the first L-shaped buckle and the second L-shaped buckle are used to engage the upper frame of the photovoltaic module.

[0011] Preferably, the third L-shaped buckle and the fourth L-shaped buckle are used to hook and secure the lower frame of the photovoltaic module.

[0012] Preferably, the third inclined plate is provided with a first locking plate, which is locked into the first locking slot; The fourth inclined plate is provided with a second locking plate, which is locked into the second locking slot.

[0013] Preferably, the third inclined plate is close to one side of the inner wall of the trapezoidal groove, and the fourth inclined plate is close to the other side of the inner wall of the trapezoidal groove, and the third inclined plate and the fourth inclined plate are symmetrically arranged.

[0014] Preferably, the first card plate is inserted into the first card slot from the side, and the second card plate is inserted into the second card slot from the side.

[0015] Preferably, the first nut is loosened and the second horizontal part is pushed upward, so that the third L-shaped buckle and the fourth L-shaped buckle move away from each other; Tighten the first nut and press the second horizontal part downward, so that the third L-shaped buckle and the fourth L-shaped buckle are close to each other, and the third L-shaped buckle and the fourth L-shaped buckle hook the lower frame of the two adjacent photovoltaic modules respectively.

[0016] Based on the same inventive principle, and to achieve the second inventive objective mentioned above, this invention provides a photovoltaic module installation method, employing a photovoltaic bracket with built-in locking and anti-loosening features as described in the first invention, comprising the following steps: Several counterweights are arranged at predetermined intervals, and the front and rear ends of the counterweights are respectively provided with sloping support blocks. Each support block is equipped with a photovoltaic bracket with self-locking and anti-loosening features as described in the first invention; The upper frames of two adjacent photovoltaic modules are engaged by the first and second L-shaped buckles of the photovoltaic bracket with self-locking and anti-loosening features described in the first invention, and the lower frames of two adjacent photovoltaic modules are hooked by the third and fourth L-shaped buckles of the photovoltaic bracket with self-locking and anti-loosening features described in the first invention.

[0017] Preferably, the counterweight is an open container filled with sand or stones.

[0018] Preferably, the bottom plate, front plate, rear plate, first side plate, and second side plate form the container; The base plate, front plate, and rear plate are integrally formed, with a first crease between the base plate and the front plate, and a second crease between the base plate and the rear plate; The first side plate engages with the bottom plate, the front plate, and the rear plate, and the second side plate engages with the bottom plate, the front plate, and the rear plate.

[0019] Compared with the prior art, the technical effects of the present invention are as follows: (1) The buckle assembly engages the frames of two adjacent photovoltaic modules. The upper frames of the two adjacent photovoltaic modules are engaged by the first L-shaped buckle and the second L-shaped buckle of the buckle assembly, and the lower frames of the two adjacent photovoltaic modules are hooked by the third L-shaped buckle and the fourth L-shaped buckle of the buckle assembly. The top surface of the frame is pressed and the lower frame is hooked. The buckle assembly holds the frame of the photovoltaic module tightly, and the buckle assembly is not easy to detach from the frame of the photovoltaic module, making the engagement more secure. By adjusting the first nut, the second horizontal part can be pushed up or down, so that the third L-shaped buckle and the fourth L-shaped buckle move away from or closer to each other, thus adapting to different width dimensions of the lower frame. It is highly adaptable, and the degree of hooking the lower frame can be adjusted by tightening the first nut. Through the double nut locking cooperation of the first nut and the second nut, the buckle assembly securely fixes the frame of the photovoltaic module.

Before being assembled into an open container, the bottom plate, front plate and rear plate are flat, and the first side plate and second side plate are flat. Flat objects occupy little space, which can greatly improve the convenience of transportation and reduce transportation costs. When assembling the open container, the first crease and the second crease can be folded, and the first side plate and the second side plate can be assembled by convex and concave fitting. The assembly efficiency is high, and sand or stones can be quickly filled into the container. The forming efficiency of the counterweight is greatly improved.

[0021] (3) The front and rear ends of the counterweight are respectively set with support blocks with slope. When installing photovoltaic modules, the buckle assembly can be pushed into the trapezoidal groove from the side, so that the first buckle plate is locked in the first buckle groove and the second buckle plate is locked in the second buckle groove. The upper frame of the two adjacent photovoltaic modules is locked by the first L-shaped buckle and the second L-shaped buckle of the buckle assembly, and the lower frame of the two adjacent photovoltaic modules is hooked by the third L-shaped buckle and the fourth L-shaped buckle of the buckle assembly. The installation efficiency of the counterweight and the buckle assembly is greatly improved. Attached Figure Description
