Description

A photovoltaic bracket with manual angle adjustment

technical field

The utility model relates to a photovoltaic support for manually adjusting the angle.

Background technique

The solar energy industry is developing at an astonishing speed in my country. Since 2011, domestic photovoltaic applications have been encouraged by policies, and the construction of large-scale power stations has developed rapidly. Some factors such as construction cost, capital recovery cycle, and annual power generation are the main factors affecting the promotion of solar power plants. Since solar power generation is directly related to sunlight intensity, time, and the placement and inclination angle of photovoltaic modules, the power generation will fluctuate with time, especially affected by seasonal factors, which will affect the stability of the power supply of the main grid. Therefore, during the construction of the power station, it is necessary to reduce the fluctuation of power supply as much as possible within the controllable range.

At present, there are mainly two types of photovoltaic supports on the market: fixed-angle photovoltaic supports and all-day tracking photovoltaic supports. Fixed-angle photovoltaic support, that is, according to the latitude of the power station construction site, the inclination angle of the support can not be adjusted. All-day tracking photovoltaic support, that is, the photovoltaic support has a braking force, and can adjust the angle at any time according to the different incident angles of solar light, so as to ensure that the sunlight can always be perpendicular to the surface of the photovoltaic module.

Since the photovoltaic support for all-day tracking can ensure the maximum incident sunlight, the power generation is much higher than that of the fixed-angle photovoltaic support. The rotation and signal processing components of the system are far from meeting the requirements of unmanned and remote management of solar power plants in terms of system stability. These components need to be maintained and repaired at any time, and the initial investment and use costs are high.

The fixed-angle photovoltaic bracket cannot be adjusted after the construction of the solar power station is completed. The sun’s altitude angle differs greatly in summer and winter, and the power generation of photovoltaic modules is greatly affected by the intensity of light. The output change is also larger. This increases the difficulty of large power grid power deployment.

Detailed ways

Below, with reference to the accompanying drawings, the utility model is described more fully, and exemplary embodiments of the utility model are shown in the accompanying drawings. However, the invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative specifications used herein interpreted accordingly.

In use, the left and right mechanism units cooperate and act synchronously in the same direction. Rotate the manual adjustment rocker 1, which drives the rotating rod 3 to rotate, and the movable part 4 will move forward or backward relative to the rotating rod 3 on it. When moving forward, the movable part 4 will approach the front support 5, thereby supporting the upper part of the photovoltaic module connection part 8, and the photovoltaic module connection part 8 will rotate around the first rotation axis 9 to reduce the pitch angle: that is, to increase its angle with the ground. When moving backward, the movable part 4 will approach the rear support 2, so that the upper part of the photovoltaic module connection part 8 will fall, and the photovoltaic module connection part 8 will rotate around the first rotation axis 9 to increase the pitch angle: that is, to reduce its angle with the ground.
