Description

Technical Field

[0002] Solar photovoltaic power generation is one of the fastest growing and most promising renewable energy industries. With the rapid development of solar photovoltaic power generation technology, the construction of solar photovoltaic power stations has become the most important link in the development process. Solar brackets, as the main components of solar photovoltaic power generation, are the most basic safety guarantee in solar photovoltaic power generation.

In the utility model, by using the first clamping block, the first slot, the vertical bar, the first clamping block, the second clamping block and other structures in coordination, stainless steel screws are not required for connection, materials are saved, costs are saved, and installation efficiency is improved. The stress point is placed in the middle from the traditional side, so that the stress of the color steel tile is balanced, the service life of the color steel is improved, and the original amount of aluminum used is reduced, making the overall structure lighter.

[0004] However, the existing technology has the following disadvantages when used: Most of the rooftop distributed projects in the industry currently use aluminum alloy rails or tripods for support. Aluminum alloy profiles are light and beautiful, and are particularly suitable for installation on light roofs or color steel tile roofs. When the photovoltaic bracket needs to be installed at a high angle on a color steel tile or light roof, a double-layer rail mode is required, i.e., an upper rail and a lower rail. At the same time, some connectors cannot splice the rails, so there are certain limitations. Utility Model Content

The aluminum alloy profile is light and beautiful, and is particularly suitable for installation on light roofs or color steel tile roofs. When the photovoltaic bracket is installed on a color steel tile or light roof and needs to be raised at an angle, a double-layer rail mode is required, that is, an upper rail and a lower rail.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] 1. The upper guide rail is supported by a connecting block, and a hexagonal bolt is movably embedded in the elliptical mounting hole, and the hexagonal bolt can be moved in the elliptical mounting hole. At the same time, an anti-gasket is movably sleeved on the surface of the hexagonal bolt, and the anti-gasket is movably connected to the surface of the slide groove, thereby preventing the hexagonal bolt from damaging the slide groove when moving. At the same time, an anti-gasket is provided on the threaded sleeve on the surface of the hexagonal bolt and is movably connected to the bottom surface of the connecting block through the anti-gasket, thereby fixing the upper guide rail, and two sets of connecting parts are provided on the surface, and the upper guide rail can be spliced ​​and installed, thereby improving the applicable scenarios.

[0017] 2. The U-shaped frame on the surface is fixed by a connecting block, and a limiting groove is opened through the inner wall of one side of the U-shaped frame. When the bidirectional screw rod on the inner wall of the limiting groove is rotated, the sliders on the opposite surfaces are driven to move relative to each other, and one side surface of the slider is slidably embedded in the inside of the limiting groove to prevent the slider from deviating from the direction when moving, resulting in the inability to perform subsequent installation. The movement of the slider drives the fixed plate on the surface to move, so that it is engaged on the surface of the lower guide rail, and can be installed on lower guide rails of different sizes at the same time, thereby improving the overall stability and simplifying the operation.
