Combined grating type intelligent photovoltaic power generation system

Abstract

The invention discloses a combined grating type intelligent photovoltaic power generation system. The system comprises an upright pillar, a biconcave crossbeam, a separating composite support, a square to circle self-lubricating composite shaft sleeve, a square shaft, photovoltaic panels, an intelligent control box, an angular sensor and a driving mechanism. The photovoltaic panel is installed on the square shaft. The square shaft is installed on the separating composite support. The separating composite support is installed on the biconcave crossbeam through T-type fastening bolts. The bottom of the crossbeam is installed on the ground through the upright pillar and a prefabricated basis. A plurality of photovoltaic panels are fixed on the square shaft to form a single row of photovoltaic row gratings. A distance is left for each row of photovoltaic row gratings. A plurality of rows of gratings form a power generation array. According to the invention, the problem of a sunshine dead zone of a traditional array-type photovoltaic power station is solved, the combined grating type intelligent photovoltaic power generation system can be combined with a fishpond water surface, farming-stockbreeding-forestry planting and breeding, an reverse-hanging agricultural greenhouse and the like, redundant sunlight is adopted for photovoltaic power generation in the upper space of the crossbeam, various kinds of agricultural breeding and production are performed in the bottom space of the crossbeam, and the multi-element three-dimensional usage of the ground is realized.

Description

technical field [0001] The invention relates to a photovoltaic system that can be combined with various types of agricultural production, in particular to a combined grid-type intelligent photovoltaic power generation system. Background technique [0002] With the development of society and the progress of science and technology; in the photovoltaic industry, the cost of photovoltaic power generation is decreasing day by day. It is expected that by 2020, clean energy with the same competitiveness as coal power generation will be realized, and the cost of power generation will be equivalent to that of coal power generation. The proportion of solar photovoltaic power generation in the human energy system will gradually increase rapidly, and the development prospects are very promising. At present, the vast majority of photovoltaic power generation systems use a wide array system with a fixed (or adjustable) inclination facing the north-south direction. The growth is unfavorab...

Problems solved by technology

[0005] Therefore, in order to solve the above-mentioned defects, the present invention solves the problem that the land under the photovoltaic panel or the agricultural shed has a large solar blind area, solves the cumbersome structure of the traditional flat single-axis independent control, and reasonably rotates the grid formed by multiple single-row photovoltaic modules. The type photovoltaic matrix avoids strong winds, reduces resistance, and also avoids the accumulation of snow on photovoltaic panels, avoids snow melting unevenly, easily leads to hot spot effects of photovoltaic modules and forms resistance damage to photovoltaic panels, greatly reducing wind and sand The damage to the photovoltaic power station reduces the operating cost and safety risk for the enterprise; at the same time, the upper beam and the secondary beam of the high support system are interwoven into a network, which is a combined grid-type intelligent photovoltaic power generation system with stronger stability, rigidity and strength; The invention interweaves into a network with strong stability, high rigidity and strength, and is suitable for installation and use in various environments; at the same time, it can track the sun for 8-10 hours throughout the day (except cloudy days), which is better than fixed electromagnetic with the same area and structure. The power generation efficiency of the module is increased by 15%-25%, thereby improving the power generation efficiency of the solar module; at the same time, the invention is small in size, light in weight, and easy to install. The power supply can be tracked, and the wind resistance performance is good

It solves the problem that the land under the photovoltaic panel or the agricultural shed has a large solar blind area; it also realizes the simplicity of the rotation control of the photovoltaic panel, and solves the cumbersome structure of the traditional flat single-axis independent control
