Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel installation, and specifically relates to a special-shaped aluminum alloy connector for installing photovoltaic panels. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that can convert solar energy into electrical energy. It consists of multiple photovoltaic cells, which are usually thin sheets made of semiconductor materials (such as silicon). When a photovoltaic panel is exposed to sunlight, it generates direct current. The principle of photovoltaic panels is based on the photovoltaic effect, that is, when sunlight shines on a photovoltaic panel, photons are absorbed and converted into electrons, which flow through the circuit to form a current, thereby generating electricity. BIPV (Building Integrated Photovoltaic), that is, building photovoltaic integration, is a technology that integrates solar power generation equipment into buildings and building materials. It belongs to a type of distributed photovoltaic power station. The biggest difference between installing photovoltaic BIPV on a new roof to replace traditional roof building materials is that the integration of photovoltaics and buildings is deeper. Using waterproof brackets to install photovoltaic BIPV, the components not only have photovoltaic power generation performance, but also become a building material in terms of basic properties. At the same time, because the building material properties of photovoltaic BIPV are more prominent, its application scenarios in buildings are also richer. Photovoltaic BIPV can be installed in application scenarios such as flat roofs and sloping roof awnings. Compared with traditional roof building materials, photovoltaic building integrated BIPV has more outstanding weather resistance, waterproofness, and economy.

[0003] Photovoltaic panel BIPV installation method, components can be installed through mounting holes or pressing blocks, pressing block installation involves adjusting the position of components and pressing blocks, and fixing them with bolts and pressing blocks to ensure that components are not struck during installation to avoid hidden cracks. The existing photovoltaic panel BIPV installation method is inconvenient to install, has high cost, and is highly dangerous for workers during installation.

[0004] The use of this technical solution in the installation of BIPV photovoltaic panels can minimize the gaps between the longitudinal and transverse joints of the photovoltaic panels. Only a small amount of rainwater dripping on the surface of the photovoltaic panels flows through the gaps into the longitudinal and transverse special-shaped main water tanks, and then converges in the longitudinal drainage tank to flow to the main water tank. The components in this solution system are tightly connected, with small gaps. The amount of rainwater flowing into the connecting tank is small, and the flow rate of the main water tank is large, achieving all-round waterproofing and water conduction with a fast flow rate, which can withstand extreme rainy days for a long time. At the same time, it can enable construction workers to install below the photovoltaic panels, avoiding the traditional BIPV photovoltaic panel top installation method where installation workers stand on the photovoltaic panel surface and step on the photovoltaic panel, causing damage to the solar cells in the photovoltaic panel to ensure the quality of the photovoltaic power station.

[0008] One side of the top of the two wedge-shaped clamping parts is integrally provided with a resistance block, one side of the two wedge-shaped clamping parts is penetrated with a screw hole 1, and the upper part of the two sides of the M-shaped middle support is penetrated with a screw hole 2, and both sides of the M-shaped middle support are provided with threaded fastening bolts that penetrate through the screw hole 1 and the screw hole 2, and the ends of the bolts are in contact with the resistance block to push the wedge-shaped clamping parts to the appropriate position to press the bottom frame of the photovoltaic panel to fix the photovoltaic panel.

[0009] Preferably, a positioning bar is integrally formed on the top of the M-shaped middle support between the two slots and is used to block and position the photovoltaic component.

[0010] Preferably, a mounting hole is formed through the folded edge at the bottom of the M-shaped middle shoulder, and a hexagonal self-tapping screw inserted into the mounting hole is arranged directly above the mounting hole.

[0012] Preferably, anti-leakage grooves are arranged on the inner sides of both sides of the main water tank, which can effectively prevent leakage at the place where the secondary main water tank overlaps the main water tank, and prevent deformation during use.

[0013] The working principle and beneficial effects of the utility model are:

[0014] The M-shaped middle shoulder mainly plays the role of supporting the weight of the entire photovoltaic component, which can effectively reduce the material cost of the main water tank. It spans the top of the main water tank. Screw holes 2 are opened on the upper part of both sides of the M-shaped middle shoulder, and slots are provided in the downward recessed part.
