Description

An angle-adjustable photovoltaic bracket

technical field

The utility model relates to the technical field of new energy, in particular to an angle-adjustable photovoltaic bracket.

Background technique

Photovoltaic power station refers to a photovoltaic power generation system that is connected to the grid and transmits electricity to the grid. It is a green energy project encouraged by the state. It can be divided into grid-connected power generation systems with batteries and without batteries. Solar power generation is divided into photothermal power generation and photovoltaic power generation. Generally speaking, solar power refers to solar photovoltaic power generation. Photovoltaic power generation products are mainly used in three aspects: one is to provide power for non-electric places; This has been implemented on a large scale in developed countries.

The function of photovoltaic support is to fix and support photovoltaic modules. The inclination angle of the existing photovoltaic support is fixed. When in use, first install and fix the photovoltaic support, then install the solar photovoltaic components on the support, and fix the components on the feet with bolts or other methods. Due to the fixed angle, photovoltaic modules can only absorb a certain amount of sunlight, and the conversion efficiency of sunlight is very limited. Generally, the angle of the existing photovoltaic support can only be adjusted before installing the photovoltaic module. If you need to adjust the angle of the bracket after installation, you need to reinstall the bracket, wasting time and labor. Application number 201520701890.9, angle-adjustable photovoltaic support. It includes a mounting mechanism for fixing photovoltaic modules, a column and an adjusting beam, the mounting mechanism is hinged on the upper end of the column, the column is provided with a through hole, the adjusting beam passes through the hole, and both ends of the adjusting beam are fixed on the installation In terms of mechanism, two locking devices are set on the adjusting beam, and the locking devices are respectively located on both sides of the column. After adopting the above structure, when adjusting the photovoltaic module, the friction between the adjustment beam and the column is reduced. One person adjusts the position of the locking device, and one person applies force to the installation mechanism to rotate the installation mechanism to a predetermined position and then lock the locking device. Yes, the operation is convenient and simple, saving time and effort, employing fewer people, reducing the torque on the installation mechanism, reducing the possible torque on the photovoltaic module, and ensuring the quality and safety of the photovoltaic module.
