Large-turning-angle scaffolding photovoltaic power station

Abstract

The invention discloses a large-turning-angle scaffolding photovoltaic power station comprising a component installing bracket and installing columns. The component installing bracket is hinged on the upper end of the installing columns. At least one telescopic supporting member is hinged on the component installing bracket. As for the distance L between the two ends of the telescopic supporting members, the maximum value of stretching is 2.5m-8m and the minimum value of contraction is 0.3m-0.8m. The component installing bracket is connected with a bracket swing device in a transmission way. A telescopic locking device is arranged on the telescopic supporting members. With application of the large-turning-angle scaffolding photovoltaic power station, large-angle overturning of the component installing bracket can be realized, and the power station has large installing capacity and reliable supporting.

Description

technical field [0001] The invention relates to photovoltaic power generation equipment, in particular to a large-scale photovoltaic power station equipment that can be turned over at a large angle. Background technique [0002] The rapid development of distributed photovoltaic power stations is mainly based on the use of vast roof resources in cities and rural areas. In addition to such roof resources, many family courtyards and square open spaces of enterprises and institutions also have good light. If it is well utilized, it can also become a good resource for the construction site of distributed photovoltaic power stations. However, such family courtyards and open spaces in the squares of enterprises and institutions are not really free and unused lands. They normally have other functions. Parking place, and the open spaces of the squares of enterprises and institutions are mostly built with parking carports and so on. There are many precedents for using the roof of th...

[0004] The above structural requirements are similar to photovoltaic power plants with altitude tracking function. In order to increase the power generation of photovoltaic power plants, a structure with altitude angle tracking function is usually adopted, that is, the pitch angle of the photovoltaic modules on the photovoltaic power plant relative to the ground can be adjusted in a timely manner. , to track the height position of the sun, there are many patent applications for this tracking structure, but usually most of the photovoltaic power generation devices of this type of tracking structure are only arranged in two rows of modules in the height direction. When the number of modules is more than two rows, the modules The size of the mounting bracket will inevitably increase. For each additional row, the front and rear dimensions of the component mounting bracket will increase by more than 1.6 meters. If the structure of an independent middle pillar is adopted, the overhang length of the component mounting bracket will increase and the rigidity will deteriorate. , if the overall rigidity of the power station is improved by simply relying on the component mounting bracket, it will inevitably increase its volume and weight, increase the burden on the column, and increase the load on the corresponding transmission mechanism, resulting in a high failure rate in actual operation and making it difficult to work normally , the use effect is not ideal; if the structure of the front and rear double columns is adopted, the structural rigidity will be better, but the tracking purpose must be achieved through the length change of the front and rear two columns, and the range of column length changes will be large. The maximum length The ratio of the minimum length to the dimension is usually more than four times, which is difficult to achieve for a telescopic column with a common structure, and for the structure of a double column, the length of the column needs to be changed to adjust the height angle. The force of the driving mechanism is very large, so it is also difficult to achieve

[0005] For the aforementioned elevation angle tracking photovoltaic power station, the variation range of the elevation angle is usually about 65 degrees. If the requirements of the above-mentioned carport type power station are to be realized, especially for the requirements of the power station in rural family gardens, the angle variation range is larger; and For the aforementioned carport power station or rural courtyard power station, usually the installed components must reach more than three rows, and the length in the north-south direction must be more than six meters in order to have a corresponding shielding effect on the vehicle. requirements with large corners will be more difficult to achieve
